Description

Mining underground auxiliary drill carriage

Technical Field

The invention relates to a mining underground auxiliary drill carriage, which is different from a drill carriage used for tunneling and mainly aims at punching holes in a tunneling roadway, such as a roadway wall.

Background

At present, auxiliary drilling work is carried out by a manually carried drilling machine when a water pipe, a cable fixing hook and the like in a mine underground tunneling roadway are fixed, and the drilling work difficulty and the labor intensity of workers are high due to the fact that the number of drilling holes is large and the working environment is bad. Especially, when the tunneling drilling machine is still in a working state, the conveyer belt for tunneling and conveying materials is also in a working state, the operation space of workers is limited, the conveyer belt can possibly collide with tunneling equipment due to slight carelessness, the operation safety coefficient is low, and the underground auxiliary punching operation becomes a difficult problem.

In addition, the height of the tunnel wall is relatively large, most of drilling positions exceed positions which are difficult to reach by workers when the workers are on the ground of the tunnel, the workers need to work by means of ladders or lifting equipment, and in more working situations, due to the small space between a conveying belt and a side wall, the lifting equipment is difficult to spread, the workers can only drill by means of the ladders, and the included angle between the ladders and the ground of the tunnel is limited by the small space, so that the stability of the drilling equipment is poor, the workers need to carry drilling equipment with low weight on the ladders, and the force for supporting the drilling equipment towards the tunnel wall or from the rear part acts against the ladders, so that the outward overturning force is expressed, and the working risk of the workers is aggravated.

Description of the embodiments

It should be noted that the direction in which the chassis 2 advances is generally referred to as the front direction, and the opposite direction is the rear direction, so that the right-left direction can be determined. In addition, the front-rear direction is also called a longitudinal direction in the technical field of chassis, and the left-right direction is correspondingly a transverse direction, for example, a cross beam and a longitudinal beam on the chassis 2 are defined based on the transverse direction and the longitudinal beam. The front-rear direction is also referred to as the longitudinal direction of the chassis 2, and the left-right direction is also referred to as the widthwise direction of the chassis 2.

It should be understood that the drill box 22 and the drill pipe that can be operated by a worker on the escalator are loaded by the mining underground auxiliary drill carriage in the embodiment of the present invention, it is obvious that the drill box 22 and the drill pipe that can be operated by the worker do not need to be loaded by a large chassis 2, and in the embodiment of the present invention, the chassis 2 with the width of less than or equal to 1000mm is selected to be enough to meet the requirement of the load capacity, and the chassis with the width of 800mm is generally also able to meet the requirement of the load capacity.

In order to obtain better support performance, the length of the chassis 2 is usually required to be more than 2000mm, so as to obtain a relatively large span and improve stability. As previously mentioned, the conveyor belt and the side walls are in a narrow region, in other words, the relatively long but relatively small width of the chassis 2 does not increase the probability of interference of the chassis 2 with the conveyor belt or the side walls.

In the preferred embodiment, the length of the chassis 2 is preferably set to be 350 mm-4500 mm, preferably 4000mm, and too long chassis 2 can affect the passing performance, such as a wheel chassis, if too long, the chassis is easy to contact with the ground. The crawler chassis has good long-direction support, so that the problem of contact with the ground of a roadway and a frame is not easy to occur. Thus, a tracked chassis is preferably employed in embodiments of the present invention. It should also be appreciated that embodiments of the present invention do not preclude the use of a wheeled chassis.

Regarding the height of the chassis 2, two parts are mainly considered, and too low and too high are not suitable, and too low may affect the trafficability, especially bad ground conditions of a roadway during tunneling. However, too high a gravity center of the chassis is not preferred, otherwise the gravity center of the chassis is high. Therefore, the height of the chassis 2 is preferably 1000 to 1500 mm.

The boom 12 shown in fig. 1 is a telescopic boom, which is a working device that is widely used, and the telescopic boom includes a fixed body and a movable body, wherein the fixed body is a concept with respect to the movable body, and means a portion of the telescopic boom connected to, for example, the support 7, and the movable body is a portion that is telescopic with respect to the fixed body. This is a standard term in the art, for example a three-stage telescopic arm comprising a fixed body and two moving bodies, nested one inside the other and driven by means of, for example, an internal or external telescopic cylinder.

The telescopic arm is carried by said chassis 2 and is also affected by the length of the chassis 2 itself, although it may be cantilevered forward a part of the way with respect to the chassis 2, its length of the fixed body being generally comparable to the length of the chassis 2, or slightly longer. Assuming that the length of the fixed body is 4000mm and a secondary telescopic arm is adopted, the maximum length of the fixed body is generally more than 8000mm, and the construction of auxiliary drilling of most roadways can be satisfied.

If three stages of telescopic arms are adopted, the fixed body can be slightly short, and still can have larger maximum elongation through three stages of adaptation.

In the structure illustrated in fig. 1 and 2, the telescopic arm adopts two stages of telescopic arms, so that most applications can be basically satisfied.

In view of stability during operation, as shown in fig. 1 and 3, a support leg 1 is further provided on the chassis 2, and the support leg 1 is preferably a hydraulic leg, and in operation, the leg of the hydraulic leg is lowered, and in a traveling state, the hydraulic leg is retracted.

The hydraulic legs are arranged at the four corners of the chassis 2, with such a relatively large span of support for a relatively good support stability.

In view of the fact that the roadway ground tends to be uneven in the tunneling stage, in order to obtain better supporting stability, the hydraulic support legs are controlled in a separate mode, and a hydraulic loop is arranged for each hydraulic support leg so as to control the elongation of the hydraulic support leg respectively.

As described above, hydraulic equipment such as telescopic cylinders has high power density, and in applications with relatively high explosion-proof requirements, only one explosion-proof motor or internal combustion engine driven hydraulic station is used, so that the explosion-proof nodes are fewer, and the safety is good.

In the configuration illustrated in fig. 1, the pump station 5, i.e. the hydraulic station, is driven by the motor 3, and accordingly the motor 3 is an explosion-proof motor. In an embodiment of the invention, the main driving part of the mining underground auxiliary drill carriage is a hydraulic part, such as a hydraulic cylinder, a hydraulic motor and the like. The boom swing assembly 6, as shown in fig. 1, may be driven by an electric motor or by a hydraulic motor which is naturally explosion proof, thus reducing the number of power points as a whole if the electric motor 3 must be used, also as a primary power point in the preferred embodiment.

In fig. 1 and 3, the motor 3 and the hydraulic station are mounted on the middle rear part of the chassis 2, and the two components are relatively heavy, and the load during operation of the boom 12 located at the middle front part can be balanced by the arrangement on the middle rear part of the chassis 2.

In view of the severe working conditions in the field during tunneling, the hydraulic station is preferably located in the equipment bay 4, while the electric motor 3 may also be located in the equipment bay 4. Regarding heat dissipation, the equipment cabin can be internally provided with an air inlet and an air outlet, and a fan is adapted to cool and exchange air.

Unlike, for example, an excavator, in the embodiment of the present invention, the boom 12 does not need to turn around, in which case, for example, the equipment bay 4 may be fixedly disposed at the middle rear side of the chassis 2, although the boom including the boom 12 is mounted on the chassis 2 by a turning support, so as to adapt to the working requirements thereof, the boom turning support formed by the boom 12 and the chassis 2 may be capable of satisfying the drilling operation requirements on one side of the roadway wall without considering 360 degrees of turning, for example, with a maximum turning angle of 90 degrees.

However, it should also be appreciated that in the condition in which the boom 12 is raised, no movement interference between the boom 12 and the fixedly arranged equipment bay 4 occurs, and that in the embodiment of the invention the implementation of a boom slewing support turnover is not precluded.

It will be appreciated that even though the equipment bay 4 is fixedly arranged, the boom swing support may be constructed as a conventional swing support structure on a construction machine, constituting the boom swing assembly 6 shown in fig. 3, which generally comprises a pair of swing bearings, the movable part of which is located on the support 7 for mounting the boom 12 shown in fig. 3, the lower end of the support 7 being provided with a gear ring, and on the chassis 2 being provided with, for example, a hydraulic motor, the output shaft of which is provided with an output gear which meshes with said gear ring for driving the support 7 in rotation.

The boom 12 is used as a part of a mechanical arm, and most of the mechanical arms used in general engineering are multi-stage telescopic arms, which are described above and will not be repeated here.

The robotic arm is used primarily to control the spatial position of components carried by the tip, commonly referred to as the tip, and for ease of description, in embodiments of the present invention, as a tip pose assembly.

It should be appreciated that the robotic arm is also generally used for tip pose adjustment, but in the embodiment of the present invention, the tip pose assembly is relatively complex, and more represents one pose adjustment, in other words, the tip pose assembly is also used for adjusting the final pose of the drill box 22, so that the drill rod is in a pose suitable for drilling.

Correspondingly, the end pose assembly is also powered by the hydraulic station; and the drill box 22 is mounted on the end pose assembly.

For remote control, the chassis side is provided with an on-board controller for controlling the operation of the chassis 2, the hydraulic station and the robotic arm and the drill box 22.

In view of the general content of the mechanical field, such as the travel control of the chassis 2, the start-stop control of the hydraulic station, the control of the mechanical arm and the drilling box work, the technical content described in the embodiments of the present invention can be combined without any creative effort by a person skilled in the art.

For example, the chassis 2 is controlled by walking, which is converted from manual start-stop on site to remote switching value transmission and execution. Therefore, the vehicle-mounted controller is controlled by a remote operation terminal, the vehicle-mounted controller side is provided with a first communication module, the remote operation terminal comprises a second communication module, and the first communication module and the second communication module are communicated through a agreed communication system, such as Bluetooth, star flash, mining local area network or other wireless communication modes. Those skilled in the art select an appropriate communication system according to the security distance and the communication quality.

In view of the fact that remote control requires operators to know on-site working conditions, and video information belongs to the most important information, video units are required to be distributed on site, the video units are defined as on-site video units, mainly cameras, two types of cameras can be configured, the first type of cameras are infrared cameras, and the second type of cameras are visible cameras, namely conventional cameras, wherein pictures of the visible cameras are clear, the content of the visible cameras is easy to recognize, and the infrared cameras can acquire information which cannot be acquired on site through the conventional cameras.

Video information is also transmitted to the operation terminal through the wireless communication module.

Accordingly, in view of the fact that the current camera itself is provided with a processing unit, the transmission of the camera can be controlled by the vehicle-mounted controller, and the processing of field information is not needed.

Regarding the camera, including at least the camera on the drill box 22 side, the current pose of the drill box 22 can be directly determined. The camera may also comprise a camera located on the front and rear side of the chassis 2 (for assisting in the forward or backward movement) or on the front and rear side of the equipment bay 4, the equipment bay 4 being located slightly higher relative to the chassis 2, so that a better view is easily obtained.

The on-board controller is connected with the on-board controller to provide on-site video information for the display module and at least comprises an on-site video unit arranged on the drill box side.

Above, regarding for example an infrared camera, an intrinsic safety type infrared camera should be used, and the rest of electric equipment or elements should all use explosion-proof or intrinsic safety type devices or equipment.

As a conventional construction of the working machine, the mechanical arm comprises a support 7 and a main arm, wherein the support 7 is used to form a swivel pair with the chassis 2 via a swivel bearing, which is then driven by, for example, a hydraulic motor.

While the main arm is used to define the working range of the arm, the boom 12 shown in fig. 1 and 3 forms the main body of the main arm, which employs a telescopic arm to define the working range of the arm.

Since it is a telescopic arm, it has at least one moving body, i.e. a secondary telescopic arm.

Accordingly, as an inherent configuration, the boom 12 should be provided with a telescopic ram and a pitching ram 10, and in fig. 1, one end of the pitching ram 10 is hinged to the underside of the fixed body of the boom 12, and the other end is hinged to the stand 7. The seat end of the fixed body of the drill boom 12 is also hinged to the support 7 by means of a hinge shaft 8.

The telescopic cylinder of the boom 12 may be internal or external, and is common knowledge in the art and will not be described in detail herein.

In a preferred embodiment, if the telescopic cylinder is located outside the boom 12 or comprises an telescopic cylinder located outside the boom 12, the mechanical arm further comprises a sub-arm 26 parallel to the boom 12, in fig. 3, the end seat 13 included in the end pose assembly constitutes a connecting rod, the boom 12 and the sub-arm 26 constitute two side frames, and the support 7 is used as a frame to constitute a parallelogram mechanism, so as to ensure that the main arm has better rigidity under the condition of relatively compact structure. And power may be achieved by telescoping of the secondary arm 26 by means of a parallelogram mechanism.

Correspondingly, the auxiliary arm 26 is provided with a push-up auxiliary cylinder.

In the structure illustrated in fig. 1 and 2, the support 7 is a vertical support, and an upper hinge support and a lower hinge support are provided on one side of the support 7, the upper hinge support is used for hinging the drill boom 12, and the lower hinge support is used for hinging the auxiliary boom 26.

In view of the fact that the mining underground auxiliary drill carriage which accords with the concept of the invention belongs to micro engineering equipment relative to conventional engineering machinery, the compactness is a remarkable characteristic. In the parallelogram mechanism, the maximum distance between the boom 12 and the auxiliary boom 26 is no more than one-eleventh to one-ninth of the length of the boom 12 in the retracted state, so that a good compactness is obtained.

The drill box 22 is mounted on the end seat 13 through an end pose adjusting mechanism, correspondingly, the main body of the mechanical arm is mainly used for conveying the drill box 22 to a given height position of a roadway preset position, the initial pose of the end pose adjusting mechanism is adjusted through driving the drill arm to rotate and support, and then the pose of the drill box 22 is finally determined through the end pose adjusting mechanism.

Accurate adjustment of the pose of the drill box 22 can be achieved with three rotational degrees of freedom, and therefore, in embodiments of the present invention, the tip pose adjustment mechanism includes three rotational degrees of freedom.

In the structure shown in fig. 1 and 3, the end position and posture adjusting mechanism includes a frame portion which cooperates with the end seat 13 to form an end rotation pair to provide a first rotation degree of freedom, and a triangle mechanism or a four-bar mechanism which takes the frame portion as a frame and has a driven member, the triangle mechanism belongs to a special modification of the four-bar mechanism, and the end cylinder 16 shown in fig. 1 includes two members, i.e., a cylinder body and a push rod, which cooperate to form a movement pair, which is also substantially the four-bar mechanism, according to a mechanism analysis theory.

The driven member, such as the rocker arm 15 shown in fig. 1, provides a second degree of rotational freedom by means of a four-bar or triangle mechanism turn-around or swing.

And the carriage of the drill box 22 is mounted to the swing arm 15 as shown in fig. 1 by a carriage swing pair to provide a third degree of freedom.

In the configuration shown in fig. 2 and 3, the carriage is a frame body with a revolving body 18 and a pushing slide rail 23 shown in the drawings, wherein the revolving body is provided with a journal to form a revolving pair by the cooperation of a bearing and a bearing seat on the swinging arm 15.

The push rail 23 cooperates with the push slide 20 shown in fig. 2 to form a track set for adjusting the position of the drill box 22 on the push rail 23. The pushing slide block 20 is driven by a pushing oil cylinder 19 shown in the figure, the cylinder body of the pushing oil cylinder 19 is arranged on the frame body, and the push rod is fixedly connected with the pushing slide block 20 so as to push the pushing slide block 20 to move on the pushing slide rail 23.

In some embodiments, the pushing achieved by the push cylinder may also be replaced with a screw-screw pair driven by a hydraulic motor. The rest of the structure is the same as the above.

In order to ensure the safety of construction, the mining underground auxiliary drill carriage is also provided with an on-board UWB (Ultra Wide Band) base station so as to carry out proximity warning on personnel provided with a UWB positioning card.

In addition, regarding the drill box 22, a commercially available drilling machine with an automatic rod withdrawing function is preferably adopted, and the characteristics and basic principles of the drilling machine are as follows: the drilling machine consists of a drilling self-return valve group, a feeding self-adaptive module, a collision valve, a limiting block and a pipeline assembly.

The drilling self-return valve group comprises an automatic control handle and a manual control handle, when the automatic handle is used, the drilling machine can automatically drill, and when the collision valve touches the limiting block, the drilling machine automatically retreats. The feeding self-adaptive module has the functions of automatically adjusting the drilling speed and the propelling pressure according to the drilling resistance, namely, when the drilling resistance is large, the rotating speed of a drilling machine motor is reduced, the torque is increased, and the propelling pressure of a propelling cylinder is increased; drilling resistance is small, and vice versa.
