Description

A priority

Priority is claimed from application No. AU 2013903212 for Australian provisional patent, the entire contents of which are incorporated herein by reference.

The technical field of the invention

The present invention relates to a guiding movement of a conveyance device up and down a shaft shaft. It has a special, but not exclusive, application for transport guides that transport materials and personnel up / down the shaft from the top of the shaft to the recess during the formation of the shaft, and it can also be used for other purposes, such as delivery personnel and materials up / down the shaft between successive lateral branches of the shaft at various underground depths.

The present invention also relates to shaft transportation systems for raising and / or lowering a shaft transportation device.

BACKGROUND OF THE INVENTION

Conventional shaft sinking operations are performed by drilling and blasting to remove materials from the shaft. The removed material is removed by means of a cleaning system, by means of which the removed material is picked up and placed in tubs (large cylindrical buckets), which are lifted to the surface on ropes running down from the mine head containing the elevator in the upper part of the mine shaft.

The methods of sinking the shaft and creating the mine, using the processes of blasting and cleaning, are slow and interrupted. In this context, “intermittent” refers to the construction of the trunk, which occurs slowly when each stage in the drilling, blasting and harvesting cycle is performed sequentially with minimal parallel execution of the processes. For example, the time between the stages of cleaning is long, because after the completion of one stage of cleaning, the cleaning equipment is removed from the bottom of the mine, the drilling equipment is lowered to the bottom of the shaft for drilling wells, then charges are installed in the wells, all equipment is removed from the bottom of the shaft, the charges are undermined, and then the next cleaning step begins.

Recently, there have been proposals to increase the speed at which sinking can occur by applying mechanical excavation technology similar to horizontal tunneling used in the civilian industry. International Patent Publication No. WO 2011/000037 A1 discloses a proposal for mine shaft drilling in which rock taken out by a drilling machine is transferred to large-capacity conveying devices in the form of skips, which are raised and lowered using a lifting system installed in the upper part of the shaft the trunk. After completion of the sinking, the lifting system and skips can then be operated to transport materials taken out during the production phase of the mine’s production life.

In the equipment disclosed in WO 2011/000037 A1, the entire contents of which are incorporated herein by reference, each loaded skip or other transportation device must be moved down the shaft shaft and through the work site, or “Galloway”. The requirements for a system that monitors and / or directs the movement of the respective transportation device change as the transportation device passes through different sections (for example, passes through Galloway, as opposed to passing from the top of the shaft into Galloway) of the shaft. The present invention provides a system that must satisfy one or more changes in system requirements.

The term "skip" refers inter alia, to a transport device used to deliver the mined material to the top of a shaft shaft. Skips of various sizes and shapes are made for both vertical and inclined trunks, and usually they include the type of transport devices with discharge from the lower hatch.

Skips differ from "buckets" in the following:

a) skips are self-tipping;

b) the properties of the skips make them suitable for use in production trunks, and until the present invention they have never been used in the creation / sinking of the barrel;

c) the skips during normal operation are permanently attached to the hoisting cable; and

d) the skips should not be able to stand freely at the bottom of the shaft (i.e. they can be extremely long and thin).

The “bucket” and “bucket”, as a rule, are cylindrical conveying devices used to transport dumped rock from the bottom of the trunk during the construction (sinking) of the trunk.

Compared to bucket skips:

a) require manual tipping

b) must be unloaded by tipping

c) attached to a lifting cable with a detachable hook to the hanging chains (or rods) at the top of the bucket (minimum 3 to maintain stability)

d) should be used in conjunction with a guide frame to provide direction in the shaft (above the working platform)

e) are uncontrollable (both in terms of rotation and vibration) below the guide system of the barrel or within the working platform, as well as below the working platform

f) regularly disconnected from the hoisting cable (usually for loading at the bottom of the barrel) during loading operations

g) must be round and have a height to diameter ratio that is stable and stand without support at the bottom of the barrel

h) must have a smooth outer surface to allow the bucket to work with shock guides, to prevent swaying, and accordingly cannot have guide joints attached to its outer surface.

Unless the context otherwise defines, the term "guide", as used herein, refers to an element along which a conveyance device moves down the shaft shaft and which counteracts or prevents both rotation of the conveyance device and lateral movements of the conveyance device relative to the shaft . Such a “guide” does not provide a driving or traction force for driving the transport device.

Summary of the invention

The present invention provides a transportation system for moving a transportation device along a shaft shaft during barrel construction, comprising:

first guide section;

a second guide section located along the shaft of the shaft in series with the first guide section, the transport device being able to move along the first guide section; and

the head section for receiving the transport device, while the head section interacts with the first guide section to enable the transport device to move from the second guide section along the first guide section when received by the head section.

The head section may include a holding section, which at least partially receives the transportation device while moving the transportation device along the first guide section.

The head section may include a landing element, which is placed on the transportation device while moving the transportation device along the first guide section.

The landing element rests against the transportation device.

The head section may be configured to depend on the transportation device while moving the transportation device and the head section along the first guide section.

The head section may be configured to allow the passage of a hoisting cable attached to the transport device, with which the transport device is raised and / or lowered along the shaft shaft.

The head section can be designed so that the lifting cable can pass through the head section to the transport device.

The transportation system can be designed so that the head section is placed on the platform when the transportation device moves from the first guide section along the second guide section.

The transportation system can be designed so that the head section does not move along the second guide section.

The shaft shaft may be substantially vertical.

The first guide section may be a variable length guide section, and the second guide section may be a constant length guide section.

The first guide section and the second guide section may limit the rotational movement and the oscillatory movement of the conveying device.

The first guide section and the second guide section can substantially prevent rotational movement and oscillatory movement of the conveying device.

The transportation system can simultaneously direct multiple transportation devices.

The first and second guide sections may guide each of several transport devices.

Personnel and / or materials may be transported in excellent or excellent transportation devices from one or more transportation devices that transport the extracted material.

The present invention further provides a guiding system for guiding the conveying device during the construction of the barrel, while raising and / or lowering the conveying device in the shaft, the system comprising:

intermediate guide section of constant length; and

the upper guide section of variable length emerging from the intermediate section to adapt to changes in the distance between the intermediate section and the upper region of the shaft shaft,

moreover, the guide system limits the rotational motion and the oscillatory motion of the transportation device.

The guides can be configured to transfer the transport device from one guide section to another.

The guide system may further comprise a lower guide section of variable length extending from the intermediate section to accommodate changes in the distance between the intermediate section and the lower region of the shaft shaft.

The lower guide section may be elongated without corresponding extension and / or contraction of the upper guide section.

The lower guide section may contract when the upper guide section lengthens. The upper guide section can actually be elongated with downward movements of the intermediate section. The lower guide section may extend between the intermediate section and the barrel forming device and extend with the movements of the barrel forming device from the intermediate section, and shorten with the movement of the intermediate section towards the barrel forming device.

In some embodiments, the upper guide section extends from the top of the barrel down to the platform where the upper guide section intersects with the intermediate section. The intermediate section is fixed on the platform and passes through the platform to the variable length guide system. The lower guide section can extend from the working platform to the barrel forming device, elongating as the barrel is formed and decreasing as the working platform (and with it the intermediate section) moves down the shaft to the barrel forming device.

The upper guide section and the intermediate section may intersect in the transition region, and the conveying device may comprise a head section and a base section, wherein the transition region is adapted to stop the downward movement of the head section, while allowing the base section to continue downward movement in the intermediate section.

The present invention may be intended for use in a substantially vertical shaft shaft.

The present invention also relates to a conveyor system for a shaft containing a guide system as described above and a lift system for raising and / or lowering the conveyor device along the guide system.

Embodiments of the system of the present invention can achieve higher shaft shaft penetration rates along with safer operation of conveyance devices along the shaft shaft.

Detailed Description of a Preferred Embodiment

• TRADITIONAL PASSAGE

Traditionally, the processes of sinking the trunk to deepen the shaft use methods of blasting and cleaning. The material is drilled at the bottom of the shaft, explosive charges are set, the bottom of the shaft is blown up and the blasted rock is loaded into the transportation device for transportation to the top of the shaft. Finally, people and materials are transported from the top of the barrel down the barrel to the bottom of the barrel and to jobs such as the job site.

• BUCKETS - TUBS

In traditional trunk sinking, tubs (large buckets) are used to transport people and breeds. This type of transportation device has been used for hundreds of years.

There are many reasons why tubs are traditionally used during trunk sinking. In order to allow easy loading of the transportation device (for example, buckets) at the bottom of the shaft, the transportation device must be:

- "open top" to allow material to be dumped into it by a loader;

- "freely movable" to allow the transportation device to be located in a desired location at the bottom of the shaft. The bottom of the shaft shaft, as a rule, is extremely uneven due to the fact that it is an exploded rock. A freely movable transport device can therefore be stably located in a specific place for filling with a loader;

- “cylindrical”, so that the open top of the conveying device is equally accessible regardless of where the conveying device is located relative to the loader during loading of the conveying device; and

- "attached to the top of the hoisting cable" is the only logical way of lifting a freely movable cylindrical transportation device.

Obviously, buckets and buckets (large buckets) provide these signs and, thus, are the main form of transportation device used in the processes of sinking / construction of the shaft.

• DISADVANTAGES OF BUCKS AND TUBS

Buckets and buckets are freely suspended and cannot have mechanisms attached to their outer surface that allow the bucket or tub to connect to the guide. One reason for this is indicated above in paragraph (h) of the BACKGROUND OF THE INVENTION. When the guide frame reaches Galloway (the work site), the bucket hangs freely, it is limited only horizontally within the work platform, but can rotate. When the bucket is below the platform, it is not possible to limit horizontal vibrations or rotation. As a result of the above, the lifting speeds of the transportation device are reduced within the work site and below the work site.

In addition, the lack of full direction of the transportation device and the general inability to fully direct the transportation device lead to health and safety risks when transporting people. This is because the absolute alignment of the transportation device with, for example, a landing pad designed with tight tolerance is not possible. This creates crushing zones and large hazardous gaps that must be closed during the landing and disembarkation of people.

Significant time is also required to level the bucket or bucket with unloading platforms, etc. and for the safe tipping of a bucket or bucket for unloading the extracted material.

Thus, buckets and tubs slow down the process of sinking the shaft and are the main cause of some health and safety risks associated with the movement of people and material in the shaft.

As part of the initiative to double the speed of the construction of the trunk and improve the health and safety of the miners, the tunnel has been developed a new system of penetration of the barrel. This system replaces drilling and rock blasting with disk cutters crushing the rock. This system also employs a material handling system that replaces buckets with skips for transporting rock and a cage for transporting people and materials.

A mechanical excavation system using disk cutters for crushing rock is implemented by a machine 12 for drilling a shaft or for passing through it located in a shaft 10, as shown in FIG. 1. Machine 12 comprises a barrel forming device, namely a cutting head 14, for digging a shaft 10, and a platform 16, on which workers install a concrete finish and tooling for the shaft in parallel with digging the shaft. Such a shaft hole drilling machine is described in WO 2011/000037, in which a rotary cutting head is mounted on the lower end of the machine’s main frame and is equipped with disk cutters for digging the rock. Drill cuttings from the cutting head are transferred up to the unloading / loading station on the working platform and moved to the skips for lifting along the barrel to the upper part of the barrel.

• DISADVANTAGES THAT YOU NEED TO OVERCOME WHEN USING SKIPS DURING CONSTRUCTION

Based on the skips used in industrial production, the present inventors realized that if the skips could be used in some way while drilling the barrel to transport and unload the material, the speed of the shaft would be higher than in the case of buckets. Also, if a single cage, which can be moved in the trunk regardless of skips, could be used to transport people and material instead of a bucket, it would be safer and more efficient. Both of these capabilities needed to solve the same problems, including ensuring the full direction of the transport device at any time along several guide systems, where the guide systems combine systems with both fixed and adaptable lengths.

In the embodiment of FIG. 1, the cutting head 14 and the working platform 16 will also lower at different times. Therefore, the height of the working platform 16 relative to the bottom of the shaft 10 will vary. In addition, for safety reasons, the guides along which the skip will move through the job site are ideally stationary.

For these reasons, more than one type of guide system is needed - in other words, a variable-length guide extending from the top of the shaft to the work site and a fixed guide passing through the work site.

In the embodiment of FIG. 1, an additional variable length guide system is required to cover the gap between the bottom of the platform and the cutting head or bottom of the shaft.

The disadvantage of such systems is that skips do not easily cross between different types of rails.

Although skips can be used during the production phase of a mine, on which a single type of guide can be used, skips are not traditionally used during the construction phase of a mine. One reason for this is that skips always require full direction. Therefore, skips are not suitable for applications in which there are several guide systems.

The authors of the present invention realized that these disadvantages are significant contributing factors to the prevailing belief that skips are not suitable for use during the construction phase.

• SYSTEM FOR THE PRESENT INVENTION

To guide the movement of the transport device, in this case represented by skip 18, the shaft 10 is equipped with a transport system 100 for the shaft containing a guide system 20, as described below, and a lifting system 102 for lifting and / or lowering the skip 18 along the guide system 20.

The lifting system 102 is attached to the upper part of the skip 18 in a known manner and applies the force necessary for the controlled lifting and lowering of the skip 18 in the shaft 10.

The guide system 20 directs the movement of the skip 18 to ensure, for example, that it does not rotate freely during the ascent / descent of the shaft 10. The skips 18 move or run along the guide system 20 for directional movement (i.e., ascent and / or descent) skip 18 in the shaft 10.

As shown in FIG. 1, the guide system 20 extends down the length of the shaft 10 to the cutting head 14.

The guide system 20 can be divided into 3 sections:

1. first or "upper" guide section 24

2. the second, "lower" or guide section 22 of the "platform", and

3. The third or guide section 26 of the "recess area."

The guide sections 24, 22, 26 sequentially extend from the upper region 28 of the shaft 10 to the recess region 29, in which the material is removed from the shaft 10 to deepen the shaft 10.

To speed up the construction phase of the mine, it is advisable not to have to provide and extend (i.e. during the deepening of the shaft shaft) separate systems for transporting the extracted material and transporting personnel and / or equipment. Therefore, it is useful if personnel and materials are transported to the work site using the same system that is used to deliver the extracted material.

TOP GUIDE SECTION 24

The upper guide section 24 extends from the guide section 22 of the platform to accommodate changes in the distance between the guide section 22 of the platform and the upper region 28 of the shaft 10. Thus, the skip 18 can move along the upper guide section 24, as shown in FIG. 1, between the upper part of the trunk (for example, above the rock loading / unloading area) and the working platform 16. It will be understood that for use in a gozenka, the upper region 28 will not be a surface level, but will be below the surface level.

As the shaft shaft 10 expands, the distance from the upper region 28 to the platform 16 increases. As a result, the distance from the upper region 28 to the guide section 22 of the platform also increases.

Therefore, the upper guide section 24 has a variable length to accommodate such changes in the distance between the upper region 28 and the guide section 22 of the platform. It may also be desirable to raise the platform 16, so the upper guide section 24 may be shortened in addition to or alternatively because it is elongated.

The upper guide section 24 comprises a pair of shelf cables 30 that extend up the shaft of the shaft 10, as shown in FIG. 2. It will be understood that, if desired, any number of cables or alternative guiding means can be used, and that the cables can be made of any suitable material (usually steel). For example, the upper guide section 24 may be wire cables or ropes, twisted steel pipe or pipe in a bay, steel tapes, chains, etc. As the upper guide section 24, any other elongated material or structure that can be wound and unwound can be used.

In a preferred embodiment, the upper guide section 24 contains several pairs of cables 30 shelf, allowing you to simultaneously direct up and down the barrel several transport devices. In one such embodiment, the upper guide section 24 contains 3 or 4 pairs of cables 30 shelf, allowing you to simultaneously direct up and down the trunk 3-4 transport device.

With further reference to FIG. 1, the shelf cables 30 are received in coils or cable drums 34, which are unwound and reeled up to extend and shorten the shelf cables 30. Thus, the upper guide section 24 is configured to extend and contract. The coils 34 are mounted in a mine head 36 extending above the open upper end of the shaft 10. The cables 30, therefore, extend straight down from the coils 34 down the shaft 10.

The coils 34 maintain sufficient tension in the cables 30 of the shelf to ensure that the transport device 18 can move up / down along the upper guide section 24 without significant rotation or deviation to the side. In other words, the shelf cables 30 help maintain the orientation and position of the conveyance device 18 when it is raised / lowered along the shaft shaft 10. In some embodiments, despite the possibility of extension and contraction, the cables 30 of the shelf will be substantially tensioned from the suspended working platforms 16 and / or other equipment, so that they will form essentially rigid elements relative to any force applied by skip 18 to the cables 30 of the shelf.

The opposite ends of the cables 30 of the shelf are connected to the upper part of the working platform 16 by any appropriate cable guy wires or other means (for example, ears, swivels). The cables 30 of the shelf can alternatively be wound through coils installed on the work platform 16. In alternative devices, the first (upper) guide section 24 can pass into the work platform 16 so that the work platform 16 is suspended at a lower point or even at the bottom of the work platform 16. It is implied that all such options are part of the present invention.

In addition, the shelf cables 30 can be connected directly to the guide section of the platform 22. However, the existing cables 30 of the shelf are connected to the platform 16, and the platform section 22 runs along a parallel rather than perpendicular path, as shown in FIG. 1. This is due to various guiding means, namely bushings 32 and channels 40, which are preferred guiding means for use with various types of guides, namely wire ropes or ropes 30 of a shelf of the upper guide section 24 and the fixed rails 38 of the guide section 22 of the platform, respectively.

GUIDING SECTION 22 OF THE WORK AREA

As mentioned above, the length of the upper guide section 24 is desirably adapted to allow it to lengthen along with the recess of the shaft 10. In contrast, the length of the platform 16 is relatively constant so that there is no flexibility (i.e., extension / contraction) for the guide section 22 working sites are not needed.

In addition, when unloading personnel and materials from the transport device 18 when it is on the work platform 16, it is desirable that the transport device 18 be stably oriented at the loading / unloading points on the work platform 16. For this reason, the guide section 22 of the work platform is rigid and fixed in place relative to the working platform 16. Thus, the skip 18 and the cage can be stopped in a stable position on the guide section 22 of the working platform, with a stable, known orientation to ensure Fast and efficient loading of the rock into the skip and safe exit of workers and equipment from the cage.

As shown in FIG. 3, the guide section 22 of the platform contains several fixed rails 38 that are rigidly fixed at various intervals on the platform 16. The fixed rails 38 slide in the channels 40 (discussed with reference to FIGS. 8 and 9) so that the skip 18 can move through work site 16.

The channels 40 are necessarily open on one side to allow the skip 18 to slip past the joints (not shown) between the fixed rails 38 and the work platform 16.

It is desirable to ensure that the skip 18 is securely mounted on the guide section 22 of the platform before it passes from the end of the upper guide section 24. Therefore, the fixed rails 38 extend a short distance above the connection between the cables 30 of the shelf (i.e., the upper guide section 24) and the working platform 16, so that the direction of the skip 18 on the fixed rails 38 begins before the cables 30 of the shelf cease to guide the head section 18 'when the transport device 18 is received into it.

A slight overlap in the direction of the skip 18 by the cables 30 of the shelf through the head section 18 'and the direction of the skip 18 directly by the fixed rails 38 also ensures that the orientation of the skip 18 is always under control.

GUIDING SECTION 26 DIGGING AREAS

Although the guide section 26 of the recess area is part of the embodiment of FIG. 1, it will be understood that such a guide section 26 may not be necessary, and that the upper guide section 24 and the lower guide section 22, or the guide section of the platform, may also be provided without providing the guide section 26 of the recess area.

Similarly, it may be desirable to provide a guide section 26 of the recess area also without providing an upper guide section 24 and a guide section 22 of the platform.

The guide section 26 of the recess area has the possibility of extension and contraction to accommodate the movements of the work platform 16 or components (for example, the cutting head 14) relative to the work platform 16. In other words, the guide section 26 of the recess area shown in FIG. 1 also represents a variable length guide section.

As the cutting head 14 moves away from the working platform 16, the guide section 2 6 of the recess area extends. Similarly, as the platform 16 moves toward the cutting head 14, the guide section 26 of the recess area is reduced.

The ability to advance the working platform 16 and the cutting head 14 at different times can be critical for the proper formation of the shaft 10. Workers on the working platform 16 finish the shaft 10 while digging the shaft 10 with the cutting head 14. Thus, the cutting head 14 will be move forward, although work platform 16 remains stationary. To this end, the guide section 26 of the recess area has a variable length and can be extended without corresponding extension and / or contraction of the guide section 22 of the platform.

In the embodiment of FIG. 1, the cutting head 14 can advance 10.5 m and then stop drilling, at this time the working platform 16 is moving 10.5 m down the shaft 10 to the cutting head 14, and finishing of the next 10 may begin on the working platform 16, 5 m of the shaft shaft section 10. Thus, when the cutting head 14 is advanced, the guide section 26 of the recess area is lengthened so that the platform 16 can remain in place until concrete is set and / or service equipment is installed (for example, pipelines , wiring, etc.), and when working The platform 16 is advancing, the guide section 26 of the recess area is shortened.

In contrast, the guide section 26 of the recess area is shortened when the upper guide section 24 lengthens. This is because the extension of the upper guide section 24 leads to a decrease in the working platform 16 to the cutting head 14. It should be noted that the upper guide section 24 is extended with the downward movements of the working platform 16 and the guide section 22 of the working platform.

The guide section 26 of the recess area comprises an assembled telescopic guide which includes several telescopic guides, such as the telescopic guide 44 shown in FIG. 5. The telescopic guides 44 ensure that there is always a guide extending the entire distance between the working platform 16 and the cutting head 14, so that the conveying device can be guided between them even when the distance changes. Rotation of the conveying device when moving along the lower guide section 26 of variable length is undesirable due to limited space and the critical nature of the equipment located between the work platform 16 and the cutting head 14 and in them. Thus, telescopic rail systems are preferred because they restrict the rotational and lateral / horizontal movement of the transport device moving along the rail system, even though the length of the rail system varies. In addition to telescopic rails, other adjustable length rails, such as cables and the like, can be used in this section.

In traditional barrel sinking operations, buckets are used during harvesting to deliver blasted rock from the shaft. Because the buckets are round, rotating is not a big problem. In contrast, the transport devices 18 provided herein have a different shape, for example, they may have a square or rectangular cross section, and therefore rotation is undesirable. For this reason, the guide section 26 of the recess area may be a system that is supplied completely separately from the entire guide system 20 described above, and be designed to be attached to an existing barrel drilling system. Such a guide section 26 of the recess area (i.e., a variable length guide system) would also be designed to guide the conveyance device along the shaft 10 and extend from the platform 16, the guide section 26 of the recess area being elongated or reduced to accommodate changes in the distance between the working platform 16 and the lower region 42 of the shaft 10.

The guide section 26 of the recess area, as shown in FIG. 5 extends to, or in the direction of, a barrel forming device, such as a cutting head 14, and thus lengthens or contracts with changes in the distance between the working platform 16 and the barrel forming device.

The telescopic guide 44 of the guide section 26 of the recess area comprises an upper rail 46 and a lower rail 48, which is slidably received at the lower end of the upper rail 46. The lower end of the fixed rail 38 is received at the upper end of the upper rail 46. When the cutting head 14 is advanced, the lower rail 48 exits the upper rail 46. In contrast, when the platform 16 advances toward the cutting head 14, the lower rail 48 is pulled into the upper rail 46.

Since the larger of any two concentrically arranged rails will represent the edge into which the channel 40 of the transport device 18 may abut during the ascent or descent (depending on whether the larger diameter rail is an upper or lower rail of two concentrically arranged rails), the channels 40 extended at their upper and lower ends.

It will be understood that the telescopic rail assembly may comprise any number of concentrically arranged rails. For example, the telescopic rail 44 may contain only one rail (for example, the upper rail 46), which receives a fixed rail 34 attached to the platform 16. The substantially fixed rail 34 and the upper rail 46 together will form a system 44 of telescopic rails. Similarly, the lower rail 48 can be sized to fit into the fixed rail 34, thus not requiring the upper rail 46.

It will also be understood that the upper rail 46 can actually extend upward along the fixed rail 38 as the work platform 16 advances and exit the fixed rail 38 as the cutting head advances, provided that there is no connection between the fixed rail 38 and the work platform 16 for a substantial length at the lower end of the fixed rail 38.

Thus, the guide system 20 comprises an upper guide section 24 of variable length extending upward from the platform 16, a guide section 22 of the platform of constant length attached to the platform 16 between the other guide sections 24, 26, and a lower guide section 26 of variable length ( i.e., the guide section of the recess area) extending downward from the platform 16 to the lower area in the shaft 10.

ο SKIP

The use of skips 18 (and 64, as described below) as transport devices is especially advantageous since the skips can be filled from above or from the side, unloaded from below, for example, when using skips with a sector shutter and corresponding valves located in the place where the skips will be unloaded. On the contrary, buckets need to be turned over, usually by hand, and therefore they usually have an open top to allow the material to fall out during unloading. For this, buckets usually have chains hanging down to the sides, which makes proper alignment of the bucket with, for example, the loading / unloading point more difficult than for skips that are fully guided all the time. Thus, skips are a safer and more effective alternative to buckets.

To allow the skip 18 to move along the cables 30 of the shelf, the cables 30 of the shelf pass in the running sleeves 32 provided on the head section 18 '(shown in Figs. 2 and 3), which receives the skip 18. The head section 18' directs the movement of the skip 18 between the upper the area 28 of the shaft 10 and the working platform 16.

Although the skip 18 may have any suitable structure, in the present embodiment it is represented by the structure indicated by the number 64, as shown in FIG. 8 and 9. In other alternative embodiments, skip 18 may comprise another device, such as an auxiliary cell 18 ''. For illustrative purposes, such an auxiliary cell 18 ″ is shown in FIG. 2 adopted in the head section 18 ′, and separately in FIG. 3.

The head section 18 '(hereinafter referred to interchangeably as the "guide frame" or "traverse") receives the auxiliary cell 18 "and helps guide the auxiliary cell 18" along the upper guide section 24 of the guide system 20, as shown in FIG. 2.

Auxiliary cage 18 ″ is used for transporting personnel (in lower cage 50), but can also be used for transporting materials (for example, exhaust pipe 41, as shown in upper cage 52 in FIG. 2).

To transition between the upper guide section 24 and the guide section 22 of the working platform, the head section 18 'is detached from the auxiliary cage 18 ". To facilitate this separation, the upper guide section 24 and the guide section 22 of the platform intersect in a transition region (not shown) where the head section 18 'is separated from the auxiliary cell 18' '.

The transition region can simply be the endpoints of the shelf cables 30 and is designed to stop the downward movement of the head section 18 ', while allowing the auxiliary cell 18' 'to continue downward movement along the guide section 22 of the platform.

For this reason, it is also desirable that separate guide means are provided on the head section 18 ′ and the auxiliary cage 18 ″. To this end, bushings 32 are provided on the head section 18 'to guide the head section 18' along the upper guide section 24, and channels 40 are provided on the auxiliary cell 18 '' to guide the auxiliary cell 18 '' along the guide section 22 of the platform as the head section 18 'is placed on the platform 16.

In FIG. 6 and 7 are side views of the head section 18 '. The head section 18 'comprises a holding section 54, a head landing section 56, a landing landing section 58, a clutch assembly 60, and guide elements 62.

In the most elementary embodiment, the guide system of the transportation device for moving the transportation device or skip 18 along the shaft shaft will contain a guide section 22 of the working platform, and skip 18 (which may contain an auxiliary cell 18 '', as shown in Fig. 2 and 3, skip 64, as shown in Fig. 8 and 9, or another type of transportation device) has the ability to move along the guide section 22 of the platform, the upper guide section 24, located along the shaft with the barrel 10 in series with the guide section 22 of the platform, and the head section 18 'for receiving the transport device 18. The head section 18 ′ cooperates with the upper guide section 24 to allow the transport device 64 ″ 18 to move from the guide section 22 of the platform along the upper guide section 24 when received by the head section 18 ′. Skip 18 has a landing element (e.g., skip landing section 114) that cooperates with a landing element (e.g., head landing section 56) of the head section 18 '. The landing element (for example, the skip landing section 114) of the skip 64 or the auxiliary cage 18 ″ is in contact with the landing element (for example, the head landing section 56) of the head section 18 'to place the transport device 18 in the head section 18'.

The head section 18 'is essentially a passive element of the system. It is passive to the extent that the movement of the head section 18 'is allowed by the movement of the transport device 18 on which the head section 18 is placed, or by the downward movement of the platform 16 when the head section 18' is placed on the platform 16. In other words, the head section 18 'depends on the transport device 18 while the transport device 18 and the head section 18' are moving along the first or upper guide section 24.

The holding section 54 is designed to hold or receive a transport device 18, such as a skip 64, as described below, or an auxiliary cell 18 ″, as described above. The holding section 54 directs the movement of the transport device 18 during movement between the work platform 16 and the upper level (e.g., surface level) of the shaft 10.

The holding section 54 is bounded by four vertical and substantially parallel corner posts 66, the ends of which are connected by beams. Beams include a group of four horizontal beams 68 in the region of the head landing section 56 and a similar group of four horizontal beams 70 in the region of the landing section 58 of the base. The corner posts 66 and beams 68, 70 together define the substantially rectangular sides, the upper and lower parts of the holding section 54.

At various latitudes of the head section 18 ', as shown in FIG. 6 and 7, it can be seen that each group of horizontal beams 68, 70 includes two shorter beams and two longer beams, so that the upper and lower parts of the holding section 54 are substantially rectangular. Therefore, the holding section 54 has two short sides and two long sides, which, respectively, are sides along which short beams and long beams extend.

Racks 66 and beams 68, 70 can be formed from any suitable material and in the present case are formed from a rectangular hollow steel profile that is closed at the ends to prevent jamming inside the debris.

The holding section 54 further has fixing beams 72 extending between the corner posts 66, typically in the plane of the rectangular sides of the holding section 54, at the points between the ends of the corner posts 66. In the present embodiment, the beams 72 are substantially horizontal and parallel to the beams 68, 70. The beams 72 are equidistant from the head landing section 56 and the landing section 58 of the base and connected at their ends to the vertical corner posts 66 by means of bolts 74.

On the longer sides of the holding section 54 (as shown in FIG. 6), pairs of diagonal struts 76 extend from opposite sides (bottom and top) of one end of one beam 72 to the opposite end of the next beam 72 vertically above and below. Only one such diagonal strut 76 extends from the uppermost and lowermost beams 72, since these beams 72 have only one adjacent beam 72, which is respectively lower and higher than the beam 72 under consideration. Together, the beams 72 and the struts 76 resist the formation of the mechanism by the holding section 54 (i.e., they resist the relative rotation of the structural members 66, 68, 72 and 76 around the bolts 74), thereby providing structural rigidity to the holding section 54.

On the short sides of the holding section 54 (as shown in FIG. 7) there are no such diagonal struts.

The number of beams 72 and spacers 76 may be selected as necessary and may, for example, be 2 or more beams 66 with an appropriate number of spacers 76.

Racks 66, beams 68, 70, 72 and struts 76 are all oriented and / or dimensioned to prevent debris from accumulating. For example, the mounting beams 72 and diagonal struts 76 may be formed from a standard steel corner profile opening inside the holding section 54. Since debris will typically fall around the holding section 54 rather than through it, the corner profile will most likely not be collect debris.

The struts, beams 68, 70, 72 and struts 76 together constitute a lattice structure or structural connection forming the holding section 54. These structural elements define the volume of the holding section 54, in which goods, transport devices, and produced material can be moved in an appropriate tank or skip. To provide the required strength, structural members are preferably made of steel, but alternatively can be made of other materials, such as aluminum, for some applications.

Passing up the inner side of the holding section 54, guides 55 are arranged for guiding the transport device 18 to and from the holding section 54 (described below). The guides 55 have the same shape as the guides of the second guide section 22 or the guide section of the platform. The guides 55 according to the present invention are made of a steel profile extending upward along the inside of the holding section 54 at the corners. The steel profile aligns (i.e., becomes jointly extended or collinear c) with the steel profile of the same size and caliber, which extends down into the work platform 16 and forms part of the guide section 22 of the work platform. The guides 55 and the guide section 22 of the working platform have a corresponding shape and go into alignment when the head section 18 'is placed on the working platform 16 to provide a consistent guide path for the skip 18 moving into or out of the holding section 54. The head landing section 56 is designed to land on the skip 18, so that the head section 18 'and the transport device 18 are moved in abutment upward from the platform 16 along the upper guide section 24. The head landing section 56 provides a rigid frame structure, from which during moving up the weight of the head section 18 'may depend on the platform 16. The head landing section 56 is bounded on the sides by corner struts 66, in the upper part by beams 68 and the head landing bars 77 and, across the long sides of the holding section 54, by the transverse elements 78. On the short sides of the holding section 54, the head landing section 56 is limited by the transverse elements 80 The transverse elements 80 extend across the short sides of the holding section 54 at a level slightly higher than the transverse elements 78 so as to be at a distance from the next lower beam 72, which is so m the same as the distance between that beam 72 and lower beam 72 next.

The head landing section 56 abuts or "fits" onto the transportation device 18 when the transportation device 18 is lifted from the platform 16 to the holding section 54. After the transportation device 18 is placed on the head landing section 56, the head section 18 'moves with the transportation device 18 when it is lifted up the upper guide section 24 from the platform 16.

The head landing bars 77 are located symmetrically around the central axis Y of the holding section 54. The symmetrical arrangement ensures that the transport device 18 is centered in the head section 18 'while lifting along the upper guide section 24. The head landing bars 77 extend substantially perpendicular between the beams 68, which extend across the long sides of the holding section 54, substantially parallel to the beams 68, which extend across the short side of the holding section 54. Head support bars 77 support the upper ends of the diagonal landing bars 82 which extend between the head landing bars 77 and the transverse elements 78 are formed. The diagonal landing bars 82 are placed on the upper part of the transport device 18, as discussed below (described below with reference to FIGS. 10 and 11).

As best seen in FIG. 7, the diagonal landing bars 82 are paired, with a pair of diagonal landing bars 82 located toward each end of the corresponding head landing beam 77, symmetrically about the central axis Y of the holding section 54.

The shock pads 84 are attached to the diagonal landing bars 82 in any suitable way to reduce the impact of the transport device 18 when it is placed on the diagonal landing bars 82. In a preferred embodiment, each shock pad is a sleeve for receiving a corresponding diagonal landing beam 82, until the diagonal landing beam 82 with the head landing bars 77 and the transverse elements 78. Impact pads 84 are located on the lower hundred onach diagonal landing bars 82. Although in the present case, each individual diagonal landing beam 82 is provided with a separate shock pad 84, a single shock pad 84 may extend along the underside of more than one diagonal landing beam 82. For example, a single shock pad 84 may extend along the lower sides two diagonal landing bars 82 of a specific pair of diagonal landing bars 82.

Impact pads 84 may be formed from any suitable material, such as rubber, neoprene, or soft metal. Impact pads 84 instead may not be designed to absorb strong impacts, or impacts in general, but may instead be formed of wear-resistant material. To compensate for the absence of shock absorption on the diagonal landing bars 82, the lifting speed of the transport device 18 can be slowed down to a “creeping speed”, which is the speed at which the landing does not cause significant vibration in the head section 18 '.

The use of shock pads 84 is preferred since they eliminate the need to Slow transport device 18 to “creep speed”. Accordingly, the time required for the transport device 18 to cross the barrel is reduced, which, in turn, contributes to an overall increase in the rate of excavation and, consequently, the rate of penetration of the barrel.

Landing section 58 of the base is designed to land on the working platform 16 after the head section 18 'has landed on it. In practice, the head section 18 'will be placed on the platform 16 when the skip 18 moves from the upper guide section 24 along the guide section 22 of the platform. After shrinkage or shortly before shrinkage of the head section 18 'on the working platform 16, the skip 18 is released from the head section 18' to continue immersion through the working platform 16 for unloading and / or loading.

The landing section 58 of the base is bounded at its corners by vertical struts 66, usually in the lower part by beams 70, and in the upper part by transverse elements 86. The transverse elements 86 extend across the sides of the holding section 54 between the corner posts 66 to which the transverse elements 86 are bolted. The base section 58 actually provides a rigid impact structural frame to support the weight of the head section 18 'when it is placed on the work platform 16.

The landing section 58 of the base has four guide plates 90 extending from the corner posts 66 on the opposite short sides of the head section 18 ', essentially perpendicular to the outside of the short sides. Each guide plate 90 is flat and lies in a vertical plane, the corresponding plate 90 tapers towards the top in the direction of the corresponding corner post 66.

The landing section 58 of the base is also equipped with shock absorbers or stops 88 extending downward from the lower ends of the vertical corner posts 66. The shock absorbers or stops 88 reduce the shock or impulse load when the head section 18 'is placed on the platform 16.

Shock absorbers or stops 88 may be mounted on corner posts 66 (or along bars 70, if necessary) by any appropriate means. At present, shock absorbers or stops 88 contain small square pieces of rubberized shock absorbing material formed on a plate (not shown), from which a bolt (not shown) protrudes. The bolt protrudes through a hole in the edge cover of the corner post 66 or another hole and is secured in place by a nut (not shown) screwed onto the bolt.

Since the platform 16 will typically be provided with rubber shock pads (described below), it may not be necessary to provide shock absorbers or stops 88.

During movement, the head section 18 'is guided along the upper guide section 24. For this, the head section 18' is provided with two pairs of bearing guide wires 92. One guide cable bearing 92 'from each pair of bearing guide wires 92 is welded or otherwise attached to the head section 18 'on the head landing section 56. Another guide wire bearing 92' 'of the corresponding pair of bearing guide wires 92 is welded or otherwise attached to the head section 18' on the landing section 58 of the base.

Each guide wire bearing 92 ', 92' 'contains a set of 96 rollers that runs along the shelf cables (indicated by a broken line Z) of the upper guide section 24. A set of rollers 96 is attached to the support 94 to mount the corresponding set of rollers 96 to the holding section 54.

Each support 94 comprises a U-shaped curved plate, the ends of the U-shaped shoulders being attached (for example, welded) to the holding section 54, and the corresponding set of 96 rollers attached (for example, welded) to the base of the U-shaped. In specific circumstances, other types of supports will be suitable, or there will be no supports at all when the sets of 96 rollers are mounted directly on the holding section 54 and it is believed that all such options fall within the scope of the present invention.

Each set 96 of rollers contains a plurality of ring rollers (not shown) located in the cylindrical casing 98. The casing 98 has two halves hinged so that the casing 98 can be closed around the cable Z of the shelf when the head section 18 'is installed.

A tapering (eg, torpedo-shaped) plate 110 is attached to the outside of the casing 96. When the head section 18 ′ moves up into the shaft shaft transport system 100, the plates 110 enter the enclosing guides (not shown) to stabilize the head section 18 ′.

It will be appreciated that the cable guide bearings 92 can be replaced with another guide mechanism (e.g., replaceable bronze bushings and / or needle slide sliders) to suit a different type of upper guide section 24 (e.g. rails mounted in the shaft shaft trim).

The head section 18 'is thus configured to extend the hoisting cable through the head section 18' to the skip 18. Therefore, when the skip 18 is placed in the head section 18 'on its ascending path, both the head section 18' and the skip 18 rise along shaft shaft 10 with a lifting cable pulling the transport device 18.

It will be understood that all the various interconnected elements (for example, elements 66, 68, 70, 72) can be connected with nuts and bolts, welding, pairs of pressure plates and other fixing methods, all of which can be used and are supposed to fall into the volume of the present invention. In addition, these elements can be formed from any suitable material having any corresponding cross section.

Shutter 60 is a Kimberly type safety shutter, although any suitable shutter may be used. The shutter has an eyelet 124 mounted on the transverse members 86 on both long sides of the holding section 54. The lever 126 is pivotally mounted in the eyelet 124 to pivot between the locked position (not shown, but the shoulder of the lever 126 is horizontal therein) and the non-locked position, as shown. The lever 126 is displaced in a locked position by a spring box 130, which extends from the diagonal strut 76 to about halfway along the shoulder of the lever 126.

The lever 126 is shaped so that it is locked in its “resting position”. The locked position at rest is achieved by locating the lever arm 126 at an angle (in this case 90 °) to the gripper 128, and not by aligning (i.e., 180 °) with the gripper 128, so that the lever 126 falls under its own weight, the gripper 128 rotates to pin 132 (see FIG. 6) of skip 18 (in the present case, skip 64, which is a skip with a sector shutter, although it will be understood that the description below can similarly be applied to other types of skip 18, such as an auxiliary cell 18 '') to thereby capture pin 132.

In FIG. 8 and 9 show a skip 64 for transporting the extracted material from the working platform 16 to a dump in the region of the upper part of the shaft lift system 100. Skip 64 has a frame 112 defining a vessel that contains the material mined during transportation.

At the top of the frame is the skip landing section 114. The skip landing section 114 forms part of the frame 112 and comprises diagonal plates 116 mounted at the same angle as the diagonal landing bars 82.

From the upper point of the skip 64, that is, where the diagonal plates 166 intersect, the sheath 118 of the rope exits. The rope cover 118 is attached to the lower end of the hoisting cable 120, thereby attaching the cable 120 to the skip 64. The hoisting cable 120 is lifted by the shaft shaft lifting system 100 to raise and lower the skip 64 along the shaft shaft (for example, along the guide section 22 of the working platform and the upper guide section 24).

The skip 64 further has runners 122. The runners 122 go along the guides 55 when the skip 64 moves into and out of the holding section 54. The runners 122 comprise angular section wear plates extending around and protruding from the corners of the frame 112. However, it will be appreciated that the runners 122 may comprise a series of rollers or any other mechanism suitable for engaging with the guides 55 to ensure proper alignment of the skip 64 with the head section 18 upon entering or leaving the holding section 54.

The "in use" case of the head section 18 'and skip 64 is shown in FIG. 10 and 11, which show a skip 64 contained in the holding section 54 of the head section 18 '. As shown in FIG. 11, during the ascent from the platform 16 or the descent to the platform 16, the diagonal landing plates 116 of the skip 64 are placed (i.e., abut) with shock pads 84 of the head section 18 '. Since the sliders 122 at the corners of the skip 64 are abutted with the guides 55 of the holding section 54, the skip 64 remains aligned with the head section 18 '.

A cable sheath 118 extends between the head landing bars 77, so that the hoist cable 120 raises and lowers both the skip 64 and the head section 18 ′ together. In this sense, the head section 18 'actually hangs from the skip 64 when moving.

In the upper part of the lifting system 100, the plates 110 of the guide rails of the bearings 92 are received into female guides to stabilize the head section 18 'and, therefore, also stabilize the skip 64. The sector shutter door 134 is then opened to release the extracted material from the skip 64. The sector shutter door 134 then closes, preparing skip 64 for the descent.

When the descent begins, the plates 110 of the guide rods of the bearings 92 slip out of the enclosing guides, and the skip 64 continues to move down the upper guide section 24. During the descent, the head section 18 'hangs from the skip 64 using the stop between the diagonal plates 116 of the skip 64 and the diagonal landing bars 82 of the head section 18 '. Thus, the descent speed of the head section 18 'is the descent speed of the skip 64.

When approaching the working platform 16, the shutters 60 are moved to the unsecured position by the trigger device 136 mounted on the platform 16. The trigger device 136 has the shape of a curved plate. The plate of the trigger device 136 extends vertically upward from the platform 16 and has a bend, so that the upper section 138 of the trigger device 136 is at an angle to the vertical, passing away from the head section 18 '.

During the descent, the head section 18 'and the skip 64 are engaged together, with the shoulder 126 of the shutter lever 60 extending horizontally and protruding from the short side of the holding section 54. When the head section 18' approaches the platform 16, the shoulder 126 of the lever engages with the upper section 138 of the release device 136. When the head section 18 'is lowered, the upper section 138 of the release device 136 overcomes the displacement of the spring box 130 and pushes the lever arm 126 to the unlocked position. Since the head section 18 'actually hangs from the skip 64, the head section 18' moves even lower towards the platform 16 in synchronization with the skip 64 even after the skip 64 has been detached from the head section 18 '.

Shortly before the head section 18 'is placed on the platform 16, the descent speed slows down to a "creeping speed" and the landing plates 90 of the head section 18' are received in the enclosing guides (not shown) on the platform 16. This ensures that the head section 18 ′ is properly aligned with the platform 16, thereby ensuring that the guides 55 are aligned with the guide section 22 of the platform on the platform 16.

The head section 18 'then stops on the shock pad installed on the platform 16. At this point, the skip 64 slides along the guides 55 from the head section 18' and onto the guide section 22 of the platform. While the cap or sheath 118 of the rope and the cable 120 are lowered between the head landing bars 77 and down through the volume of the holding section 54.

It will be understood that whenever the skip 64 is within the work platform 16, the rope passes between the head landing beams 77 through the holding section 54.

After the skip 64 has been filled and lifted, the skip 64 is moved from the guide section 22 of the platform to the holding section 54 along the guides 55. The lifting speed of the skip 64 immediately before shrinkage with the head section 18 'is lowered to "creeping speed" to ensure that landing is controllable. When the diagonal landing plates 11 of the skip 64 are seated on the diagonal landing bars 82 of the head landing section 56 of the head section 18 ′, with the rope sheath 118 being centrally located between the head landing bars 77, the speed of the skip 64 is increased.

Immediately after the head section 18 ′ is fitted with a skip 64, the end of the lever arm 126 moves up against the vertical portion of the trigger device 136. When the end of the lever arm 126 reaches a bend, it begins to move along the upper section 138 of the trigger device 136. At this time, the spring box 130 gradually pushes the lever arm 126 back to the locked position as the head section 18 'and the skip 64 rise.

Thus, the skip 64 and the head section 18 'are automatically engaged together to rise from the platform 16 to the upper part of the shaft shaft lifting system 100 to discharge the contents of the skip 64.

The head section 18 'is therefore only capable of lifting or lowering synchronously (that is, when planted) with the skip 64. The head section 18' is essentially a passive structure that allows the skip 64 to smoothly transition between a rigid fixed guide system, such as a guide section 22 of the platform, and a variable length guide system, such as shelf cables, forming part of the upper guide section 24. In fact, the head section 18 'is part of the movable guide frame that it picks up skip 64, when the skip 64 moves along the upper guide section 24, the head section 18 'acts as an interface between the skip 64 and the guides of the upper guide section 24. The person skilled in the art will understand that the shutters 60 are, in many cases, only a precaution, since the position of the head section 18 'on the skip 64 is established by the interaction between the guides 55 and the sliders 122 and the fit of the diagonal landing beams 82 of the head section 18' on the diagonal plates 116 of the skip 64.

In FIG. 12-14 show an alternative version of the head section 142 and transport device 140 for transporting both parts and workers up and down the shaft.

The head section 142 comprises a frame 144 having a square horizontal cross section. Frame 144 comprises a combination of horizontal and diagonal struts and brackets, together constituting a rigid structure. The frame 144 is open on one side to facilitate access to a section 146 for transporting parts on top of a part 148 for transporting personnel of the transport device 140.

The frame 144 again comprises corner posts 150 formed of a steel profile and bearings 92 ', 92' ', as discussed above with respect to the head section 18'.

The head section 142 comprises flat head landing beams 152 onto which the transport device 140 is placed while the transport device 140 is moved between the work platform 16 and the upper part of the mine shaft lifting system 100. The flat head landing bars 152 and the head section work in the same way as the head section 18 ', and the features of the head section 142 will be apparent from the description above associated with the head section 18'.

The section 146 for transporting the parts of the transport device 140 is limited to four corner posts 154. The upper end 156 of each corner post 154 is narrowed or tilted inward to help align the corner posts 154 with the corner profile of the corner posts 150. To reduce friction between the corner posts 154 of the transport device 140 and wear racks 158 are attached to the corner posts 150 of the head section 142, wear plates 158 are attached above and below the section 146 for transporting parts in pairs. The wear plates 158 of each pair abut against opposite edges or shoulders of the angular profile of the corner posts 150 of the used head section 142.

Wear plates can be fastened together using any suitable method and can be formed from any suitable material.

The transport device 140 has a landing block 160. The landing block 160 contains a pair of landing bars 162 attached to the upper part of the transportation device 140 and located for landing on the landing bars 152 of the head section 142, and a rope block 164 that extends between the head landing bars 152 of the head section 142, when the transport device 140 is seated in the head section 142. The rope block 164 is extended outwardly in a lower direction to help align the rope block 164 in the center between the head boarding b Rus 152 of the head section 142, thereby locating the landing bars 162 of the transport device 140 on the head landing bars 152 of the head section 142.

The personnel transport part 148 is located below the part transport section 146. The length of the section 146 for transporting parts is the same as the length of the head section 142, so that the part 148 for transporting personnel is located under the lowest beam 166 of the head section 142, while the head section 142 and the transport device 140 are moved together.

The personnel transporting part 146 comprises guides of the working platform in the form of female guide brackets 168 that move along the first guide section 22. In contrast to the head section 18 ′ and the skip 64 described above, the guides (i.e. the corner posts) 144 the head section 142 do not become jointly extended with the first guide section 22. Instead, when the transport device 140 moves to or from the head section 142, the corner posts 154 are guided to the head section 142 by the corner posts 150 section 142. When the transport device 140 moves along the guide section 22 of the platform extending along the platform 16, the female guide brackets 168 slide along the rails, in this case a C-shaped steel profile, with the C-profile side open, facing away from the device 140 transportation guide section 22 of the platform.

Although no shutter is shown in the present embodiment, it will be appreciated that a shutter or other connecting device will be used to connect the transport device 140 to the head section 142. In fact, especially when the transport device carries people, there will often be a legal requirement for such a safety device. installed to ensure the existence of a mechanical connection between the head section 142 and the transport device 140.

In the upper part of the lifting system 100, the plates 110 of the guide rods of the bearings 92 are received in the female guides in order to stabilize the head section 142 and thereby also stabilize the transport device 140. Then people and materials may be loaded into or unloaded from the transport device 140.

When the descent begins, the bearing guide rails 110 of the bearings 92 slide out of the female guides and the transport device 140 continues to move down the upper guide section 24. During the descent, the head section 142 hangs from the transport device 140 by means of an abutment between the landing bars 162 of the transport device 140 and the upper landing bars 152 of the head section 142. Thus, the descent speed of the head section 142 is the descent speed of the transport device 140.

Shortly before the head section 142 is placed on the work platform 16, the female landing brackets 170 of the head section 142 receive incoming pins (not shown) on the work platform 16. Shortly before the head section 142 is placed on the work platform 16, the female guides 168 receive the end of the incoming guide rails of the platform section 22 extending upward a short distance from the platform 16. The lower portion of the female guide rails 168 is widened outward so as to compensate There is a slight mismatch between the female guide brackets 168 and the guide rail of the platform section 22.

The lower female guide brackets 168 receive the upwardly extending upstream portion of the platform guide section 22 and, as the transport device 140 gradually descends, the upper female guide brackets 168 eventually receive the upstream projection section of the platform guide section 22.

Just before the transport device 140 and the head section 142 are lowered until the head section 142 comes into contact with the working platform, the landing brackets 170 of the head section 142 receive incoming pins (not shown) on the working platform 16. This ensures that the head section 142 is correctly aligned with the working platform 16.

At this time, the head section 142 stops on the shock pad installed on the work platform 16. At this point, the transport device 140 slides along the guides (constituting the corner posts 150) from the head section 142 and onto the guide section 22 of the work platform. While the cap or sheath 118 of the rope and the cable 120 are lowered between the head landing beams 152 and down through the volume of the head section 142.

The landing process can occur while the transport device 18 moves down to the platform 16 at substantially the same speed as the transport device 18 descends along the first guide section 24. Alternatively, the transport device 18 may be slightly slowed down before the head section 142 is placed on the work platform 16. In both of these cases, shock pads may be provided to reduce the shock load of the head section 142 on the work platform 16. As another alternative, the device GUT transport 18 can be slowed to a "creeping speed," before planting head section 142 on the platform 16.

It will be understood that whenever the transport device 140 is within the work platform 16, the rope passes between the head landing bars 142 through the head section 142.

After the transportation device 140 has been filled and / or its load has been laid out and the transportation device 140 has been lifted, the transportation device 140 is moved from the guide section 22 of the platform to the head section 142 along the guides (corner posts 150). The lifting speed of the transport device 140 immediately prior to shrinkage with the head section 142 is lowered to a “creeping speed” to ensure that the landing is controllable. When the landing beams 162 of the transport device 140 are seated on the upper landing beams 152 of the head section 142, with the rope sheath 118 being centrally located between the head landing beams 152, the lifting speed of the transportation device 140 increases.

The head section 142, therefore, is only able to rise or fall in synchronization with the transport device 140 (i.e., when placed on it). The head section 142 is essentially a passive structure that allows the transport device 140 to smoothly transition between a rigid fixed guide system, such as the guide section 22 of the platform, and a variable length guide system, such as shelf cables, which are part of the upper guide section 24. In fact, the head section 142 forms part of the movable guide frame, which picks up the transport device 140 when the transport device 140 moves in the upper direction the main section 142, the head section 142 acts as an interface between the transport device 140 and the guides of the upper guide section 24.

Finally, several transport devices can operate simultaneously in the barrel. The first and second guide sections of the conveying system can guide each of several conveying devices. Personnel and / or materials may be transported in excellent or excellent transportation devices from one or more transportation devices that transport the extracted material.
