Description

Supporting device

Technical Field

The present disclosure relates to the field of support and protection of a winding chamber, and in particular, to a support device for supporting a winding chamber.

Background

The winch chamber is a space dug in the underground rock mass and used for placing a winch device. The roof of the winch chamber is affected by the factors of ground pressure, rock burst and the like, and has the phenomenon of separation layer falling. In view of the potential for equipment damage and injury to personnel from the rock falling off, support devices are typically provided within the windlass chamber to support the canopy and protect the equipment and personnel.

The winch chamber is usually constructed in a full face tunneling mode, and is formed at one time and then is used for centralized deslagging. The conventional supporting device has a complex structure, is difficult to construct and requires a large construction space, so that the supporting device is usually reconstructed after slag discharge is completed.

However, the occurrence of the delamination phenomenon is random, which may occur in the construction process of concentrated slag tapping. In the construction of concentrated slag discharging process, the space exposure area is larger, the roof control height is higher, the roof control difficulty is higher, and therefore the separation layer falling phenomenon can bring about larger potential safety hazard.

Disclosure of Invention

In view of the above, the present disclosure provides a supporting device for supporting a winch chamber, so as to at least solve the problem of greater potential safety hazard in the centralized deslagging process.

The supporting device is used for supporting the winch chamber. The present disclosure provides a support device comprising: the anchor net comprises a plurality of rectangular anchor net units; the plurality of anchor net units are arranged in an array manner, and any two adjacent anchor net units are partially overlapped, so that the anchor net covers the roof of the winch chamber and avoids a rope outlet for a rope to extend out of the winch chamber; and a plurality of groups of anchor rods embedded into the rock stratum of the roof of the winch chamber to anchor the plurality of anchor net units to the roof of the winch chamber respectively; each group of anchor rods comprises a central anchor rod and four surrounding anchor rods, the central anchor rod anchors the middle part of a corresponding anchor net unit, the four surrounding anchor rods anchor four corners of the anchor net unit respectively, and any two adjacent groups of anchor rods share two adjacent surrounding anchor rods.

Compared with an anchor net which can completely cover the roof of the winch chamber, the anchor net formed by smaller anchor net units can bring flexibility for construction. On the one hand, the space of the winch chamber before slag concentration is relatively narrow, and the smaller anchor net unit is more convenient for construction. On the other hand, the anchor net composed of a plurality of anchor net units can more conveniently avoid a rope outlet for the rope to extend out of the winch chamber during construction, compared with the whole anchor net, the whole anchor net needs to be cut off after being unfolded to shield the part of the rope outlet, and the difficulty of construction in a narrow space is increased. Meanwhile, the anchor net units and the anchor rods are arranged in the arrangement mode, so that the overall strength of the spliced anchor net is ensured to be close to that of a whole anchor net on the basis that the anchor net is reliably anchored at the roof of the winch chamber. Therefore, the supporting device has the advantages of simpler structure, more convenient construction, suitability for construction in a narrower space and better overall strength. Therefore, after the winch chamber is formed and constructed and before the centralized slag is discharged, the supporting device can be constructed to serve as a temporary supporting device, so that constructors are protected, and the construction safety in the centralized slag discharging process is improved.

In addition, the supporting device can be used as a construction foundation of a subsequent permanent supporting device. That is, after the completion of the concentrated slag discharge, the bracket mechanism may be further constructed on the basis of the temporary supporting device to upgrade the temporary supporting device to a more solid permanent supporting device. In this way, the aim of protecting the constructors during the concentrated deslagging process can be achieved, and the workload of the subsequent construction of the permanent supporting device can be reduced (that is, the temporary supporting device does not need to be dismantled, and the top supporting part does not need to be built again).

In one possible implementation, the support device further comprises a support structure located on the underside of the anchor net to support the anchor net.

After the centralized deslagging is finished, a support structure can be constructed on the lower side of the anchor net, and the anchor net is supported by the support structure, so that the temporary supporting device is upgraded into a permanent supporting device with better balance.

In one possible implementation, the support device further comprises cement that bonds the roof of the windlass chamber, the anchor net and the top of the bracket together.

After the support structure is built, the roof of the winch chamber, the anchor net and the top of the support can be glued into a whole by using the cementing agent, so that the strength of the supporting device is further improved, the safety of the winch chamber is further improved, and better protection effect is achieved on personnel and winch equipment.

In one possible implementation, the support structure includes: the longitudinal beam is positioned in the middle of the winch chamber in the transverse direction and extends longitudinally; the arched struts are divided into a plurality of pairs of arched struts which are arranged at intervals in the longitudinal direction, and each pair of arched struts is respectively positioned at two sides of the longitudinal beam in the transverse direction and is opposite to the longitudinal beam in the transverse direction; the inner end of each arch support is fixed on the longitudinal beam, and each arch support gradually extends downwards along with outwards; and the plurality of upright posts comprise a plurality of first upright posts extending along the up-down direction, and the upper ends of the plurality of first upright posts are respectively fixed at the outer ends of the plurality of arch support rods so as to support the plurality of arch support rods.

The support structure has the advantages of simple structure, convenient construction, high structural stability and the like. The supporting device with the support structure can reliably support the winch chamber, and personnel and winch equipment in the winch chamber can be better protected. In addition, for such a stent structure, the stringers and the plurality of arched struts of the stent structure may be glued with cement to the roof and anchor net of the windlass chamber.

In one possible implementation, the plurality of columns further includes a plurality of second columns extending in the up-down direction and arranged at intervals in the longitudinal direction, top ends of the plurality of second columns being fixed to the stringers to support the stringers.

Since the stringers are subjected to the greatest stresses, they need to be supported more. By arranging a plurality of second uprights at intervals in the longitudinal direction, the stringers can be supported more reliably, thereby greatly improving the overall strength of the bracket structure.

In one possible implementation, the stringers have an i-shaped cross section such that the stringers define a pair of recesses on each side in the transverse direction, the two inner ends of each pair of arch struts being respectively embedded in a pair of recesses and fixed to the stringers by means of welding.

With this configuration, the arched struts will be able to exert an upward thrust on the stringers, thereby supporting them more reliably. In addition, the inner ends of the arch support rods are embedded in the concave parts of the longitudinal beams and welded to the longitudinal beams, so that the connection between the arch support rods and the longitudinal beams has higher strength, and the support structure has higher overall strength.

In one possible implementation, the support structure further comprises a plurality of abutments, each of which is at least partially buried under the ground of the firing chamber, and a plurality of posts are respectively fixed to the plurality of abutments.

By the implementation mode, the bottom ends of the upright posts can be conveniently and reliably fixed on the ground of the winch chamber, so that the support structure is ensured to have enough integral strength.

In one possible implementation, the plurality of base stations includes a plurality of first base stations and a plurality of second base stations, the plurality of first base stations are respectively fixed to the plurality of first upright posts, and the plurality of second base stations are respectively fixed to the plurality of second upright posts; any two longitudinally adjacent first base stations are respectively fixed at two ends of a first connecting rod buried under the ground of the winch chamber, any two transversely opposite first base stations are respectively fixed at two ends of a second connecting rod buried under the ground of the winch chamber, and any two adjacent second base stations are respectively fixed at two ends of a third connecting rod buried under the ground of the winch chamber and above the second connecting rod.

Through burying a plurality of connecting rods in the underground, can connect into overall structure with a plurality of baseplates, and then can further improve supporting structure's bulk strength. In addition, in view of the fact that the second upright is subjected to a relatively high pressure, the second abutment to which it is fixed tends to sag, and therefore, in the present implementation, the third connecting rod is arranged above the second connecting rod. Thus, the second connecting rod and the first base station provide good support for the third connecting rod and the second base station, and the second base station is prevented from sinking.

In one possible implementation, the support device further comprises at least one stress sensor attached to the at least one upright, respectively.

The stress condition of the stand column can be monitored through the stress sensor, and then the stress condition of the top plate (namely the whole of the anchor net, the longitudinal beam and the arch support rod which are glued together) of the supporting device can be monitored. When the roof is monitored to be stressed beyond a preset threshold, a safety strategy, such as evacuating personnel, dismantling equipment or reinforcing bracket devices, and the like, can be formulated in time.

In one possible implementation, the support device further comprises: a controller in communication with the at least one stress sensor to receive stress signals from the at least one stress sensor; and the controller is in communication connection with the alarm device so as to send an alarm starting signal obtained according to the stress signal to the alarm device.

In such an implementation, when the stress sensor senses that the roof is stressed beyond a preset threshold, the controller generates and sends an alarm on signal to the alarm device. Upon receipt of the alarm activation signal, the alarm device activates an alarm, for example by means of sound or light. In this way, the relevant personnel can notice potential safety hazards at the first time and then timely formulate a safety strategy.

Detailed Description

Embodiments of the present disclosure are exemplarily described below with reference to the accompanying drawings. It should be understood that the implementations of the present disclosure may be varied and should not be construed as limited to the embodiments set forth herein, which are presented only for a more thorough and clear understanding of the present disclosure.

A windlass chamber 20 with windlass means 10 positioned therein is shown in fig. 1 and 2. Referring to fig. 1 and 2, the winding chamber 20 is provided with a rope outlet 22 communicating with a rope passage 21 extending obliquely upward, and the rope 11 wound on the winding shaft of the winding device 10 extends into the rope passage 21 through the rope outlet 22. A support device 30 for supporting a windlass chamber 20 provided in an embodiment of the present disclosure is shown in fig. 3. Referring to fig. 3, the support device 30 includes an anchor net 31 and a plurality of sets of anchor rods 32. In one example, the hoisting device 10 may be used to hoist ore excavated from a mine shaft, or to lower and/or hoist personnel and/or other items.

The anchor net 31 is composed of a plurality of anchor net units 311, wherein each anchor net unit 311 has a rectangular shape. The plurality of anchor net units 311 are arranged in an array, and any adjacent two anchor net units 311 are partially overlapped such that the anchor net 31 covers the ceiling of the winding chamber 20 and avoids the rope outlet 22 through which the rope extends out of the winding chamber 20. Multiple sets of anchor rods 32 are embedded in the rock strata of the roof of the windlass chamber 20 to anchor multiple anchor net units 311 to the roof of the windlass chamber 20 respectively.

Fig. 4 shows four adjacent anchor net units 311 and corresponding anchor bar sets 32. It should be understood that the anchor net 31 is not limited to include only four anchor net units 311, and that other anchor net units 311 may be arranged in the manner described with reference to fig. 4. Referring to fig. 4, a right edge portion of the anchor net unit 311a overlaps a left edge portion of the anchor net unit 311b, a lower edge portion of the anchor net unit 311a overlaps an upper edge portion of the anchor net unit 311c, a lower edge portion of the anchor net unit 311b overlaps an upper edge portion of the anchor net unit 311d, and a right edge portion of the anchor net unit 311c overlaps a left edge portion of the anchor net unit 311 d.

With continued reference to fig. 4, each set of anchors 32 includes a central anchor 32a and four surrounding anchors 32b,32c,32d,32e. The central anchor rod 32a anchors the middle portion of a corresponding anchor net unit 311, and four surrounding anchor rods 32b,32c,32d,32e anchor the four corners of the anchor net unit 311, respectively. Any two adjacent sets of anchors 32 share two adjacent surrounding anchors 32. For example, the anchor group corresponding to the anchor net unit 311a shares anchors 32b,32e with the anchor group corresponding to the anchor net unit 311b, the anchor group corresponding to the anchor net unit 311a shares anchors 32d,32e with the anchor group corresponding to the anchor net unit 311c, the anchor group corresponding to the anchor net unit 311c shares anchors 32b,32e with the anchor group corresponding to the anchor net unit 311d, and the anchor group corresponding to the anchor net unit 311b shares anchors 32d,32e with the anchor group corresponding to the anchor net unit 311 d.

The anchor net 31 composed of the smaller anchor net units 311 can provide flexibility for construction as compared to the anchor net 31 which can entirely cover the ceiling of the windlass chamber 20. On the one hand, the space of the winch chamber 20 before centralized deslagging is smaller, and the smaller anchor net unit 311 is more convenient to construct. On the other hand, the anchor net 31 composed of the plurality of anchor net units 311 can more conveniently avoid the rope outlet 22 for the rope 11 to extend out of the windlass chamber 20 during construction, in contrast to the whole anchor net 31, which requires cutting out the part for shielding the rope outlet 22 after being unfolded, which increases the difficulty of construction in a narrow space. Meanwhile, the anchor net units 311 and the anchor rods 32 are arranged in the arrangement mode, so that the overall strength of the spliced anchor net 31 can be ensured to be close to that of a whole anchor net 31 on the basis that the anchor net 31 is reliably anchored at the roof of the winch chamber 20. Therefore, the support device 30 has simple structure, convenient construction, suitability for construction in a narrow space and better overall strength. Therefore, after the molding construction of the winch chamber 20 and before the centralized slag discharge, the supporting device 30 can be constructed as a temporary supporting device 30 so as to protect constructors and improve the construction safety in the centralized slag discharge process.

In addition, such a supporting device 30 may serve as a construction foundation for a subsequent permanent supporting device 30-1 (a description about the supporting device 30-1 will be given below). That is, after the completion of the concentrated slag discharge, a bracket mechanism may be further constructed on the basis of such temporary supporting means 30 to upgrade such temporary supporting means 30 to a more solid permanent supporting means 30-1. In this way, it is possible to achieve both the purpose of protecting the constructors during the concentrated slag discharge and the effort of the subsequent construction of the permanent supporting means 30-1 (that is, without dismantling the temporary supporting means 30 and without setting up the top supporting portion again).

The support device 30 provided by one embodiment of the present disclosure is exemplified above, and the support device 30-1 provided by another embodiment of the present disclosure is exemplified below. It should be noted that the supporting device 30 and the supporting device 30-1 have many identical or similar elements, and for the sake of brevity, identical or similar elements will be given identical reference numerals to omit duplicate descriptions. The support device 30 may be referred to as a temporary support device, the support device 30-1 may be referred to as a permanent support device, and the permanent support device 30-1 may be constructed based on the temporary support device 30.

Referring to fig. 5 to 7, the supporting device 30-1 may include a supporting structure located at an underside of the anchor net 31 to support the anchor net 31, in addition to the anchor net 31 and the plurality of group anchors 32. After the concentrated slag discharge is completed, a bracket structure can be constructed at the lower side of the anchor net 31, and the anchor net 31 is supported by the bracket structure, so that the temporary supporting device 30 is upgraded into a permanent supporting device 30-1 which is more compatible.

Referring to fig. 5 and 6, the support device 30-1 may further include cement 34, the cement 34 bonding the roof of the windlass chamber 20, the anchor net 31 and the top of the bracket as a whole. The cement is not particularly limited in this disclosure, as long as the roof of the windlass chamber 20, the anchor net 31 and the top of the bracket can be glued together. As one example, the cement may be concrete. As a more specific example, the cement may be a C25 strength concrete, and wet mix concrete may be sprayed onto the roof of the windlass chamber 20 during construction to integrate the roof of the windlass chamber 20, the anchor net 31 and the top of the support.

According to the implementation manner, after the bracket structure is constructed, the roof of the winch chamber 20, the anchor net 31 and the top of the bracket can be glued into a whole by using the glue 34, so that the strength of the supporting device 30-1 is further improved, the safety of the winch chamber 20 is further improved, and a better protection effect is achieved for personnel and winch equipment.

Referring to fig. 7, the bracket structure may include a stringer 331, a plurality of arched struts 332, and a plurality of uprights 333. Stringers 331 are located in the middle of the windlass chamber 20 in the transverse direction and extend longitudinally. The plurality of arch struts 332 are divided into a plurality of pairs of arch struts 332 spaced apart in the longitudinal direction, each pair of arch struts 332 being located on both sides of the stringers 331 in the lateral direction and being opposed in the lateral direction, respectively. The inner end of each arch post 332 is secured to the stringer 331 and each arch post 332 extends progressively downwardly as it goes outwardly. The plurality of columns 333 includes a plurality of first columns 333a extending in the up-down direction, and upper ends of the plurality of first columns 333a are respectively fixed to outer ends of the plurality of arch struts 332 to support the plurality of arch struts 332.

The support structure has the advantages of simple structure, convenient construction, high structural stability and the like. The supporting device 30-1 with the supporting structure can reliably support the winch chamber 20, and personnel and winch equipment in the winch chamber are better protected. In addition, for such a bracket structure, stringers 331 and a plurality of arched struts 332 of the bracket structure may be glued with cement 34 to the roof of the firing chamber 20 and the anchor net 31.

It is to be understood that in this disclosure, directional descriptions such as "upper," "lower," "transverse," and "longitudinal" are relative and not absolute. These directional descriptions are applicable when the elements of the disclosure are in the pose and pose positions shown in the figures. In the drawings of the present disclosure, an arrow z+ and an arrow Z-are used to indicate an upper side and a lower side in the up-down direction, respectively; arrow x+ and arrow X-are used to indicate opposite sides in the lateral direction, respectively; arrow y+ and arrow Y-are used to indicate opposite sides in the longitudinal direction, respectively.

With continued reference to fig. 7, the plurality of upright posts 333 may further include a plurality of second upright posts 333b extending in the up-down direction and spaced apart in the longitudinal direction, with top ends of the plurality of second upright posts 333b being fixed to the stringers 331 to support the stringers 331. Since the stringers 331 are subjected to the greatest pressure, they need to be supported separately. By the plurality of second upright posts 333b being arranged at intervals in the longitudinal direction, the side member 331 can be supported more reliably, thereby greatly improving the overall strength of the bracket structure.

In one particular example, the plurality of second uprights 333b may be two second uprights 333b, the two second uprights 333b being located at respective ends of the stringer 311. Of course, in other examples, the plurality of second posts 333b may also be three or more second posts 333b.

Referring to fig. 8, as one example, the stringers 331 have an i-shaped cross section such that both sides of the stringers 331 in the lateral direction define a pair of recesses 3311, respectively. The two inner ends of each pair of arch struts 332 are respectively embedded in a pair of recesses 3311 and fixed to the stringers 331 by welding.

With this configuration, the arched struts 332 will be able to apply an upward thrust to the stringers 331, thereby more reliably supporting the stringers 331. In addition, the inner ends of the arch struts 332 are embedded in the concave portions 3311 of the stringers 331 and welded to the stringers 331, which results in a high strength of the connection of the arch struts 332 to the stringers 331 and thus a high overall strength of the stent structure.

With continued reference to fig. 7, the support structure may further include a plurality of abutments 334, each abutment 344 at least partially embedded in the ground of the firing chamber 20, with a plurality of posts 333 secured to the plurality of abutments 334, respectively. By this implementation, the bottom ends of the plurality of columns can be conveniently and reliably fixed to the ground of the windlass chamber 20, thereby ensuring that the support structure has sufficient overall strength. As one implementation, the abutment 334 may be implemented as a concrete casting 334. As a particular implementation, referring to fig. 9, a embedment 3341 is embedded on a concrete casting 334, and the post 334 is secured to the embedment 3341 and, in turn, to the concrete casting 334. As a more particular implementation, the embedment 3341 may be implemented as a steel plate.

Referring back to fig. 7, the support device 30-1 may further include at least one stress sensor 351, the at least one stress sensor 351 being attached to the at least one upright 333, respectively. By means of the stress sensor 351, the stress condition of the upright 333, and thus of the top plate of the supporting device 30-1 (i.e. the whole of the anchor net 31, the stringers 331 and the arched struts 332 glued together) can be monitored. When the roof is monitored to be stressed beyond a preset threshold, a safety strategy, such as evacuating personnel, dismantling equipment or reinforcing bracket devices, and the like, can be formulated in time.

With continued reference to FIG. 7, the support device 30-1 may also include a controller 352 and an alarm device 353. The controller 352 is communicatively coupled to the at least one stress sensor 351 to receive stress signals from the at least one stress sensor 351. Meanwhile, the controller 352 is communicatively connected with the alarm device 353 to transmit an alarm-on signal obtained from the stress signal to the alarm device 353. As one example, the alarm device 352 may include a light alarm unit and a sound alarm unit to implement an alarm function through an acoustic, optical signal.

In such an implementation, when the stress sensor 351 senses that the roof force exceeds a preset threshold, the controller 352 will generate and send an alarm on signal to the alarm device 353. Upon receipt of the alarm activation signal, the alarm device 352 activates an alarm, such as by sound or light. In this way, the relevant personnel can notice potential safety hazards at the first time and then timely formulate a safety strategy.

A bracket structure of a support device according to another embodiment of the present disclosure is shown in fig. 10. Referring to fig. 10, in the current embodiment, the plurality of abutments 334 includes a plurality of first abutments 334a and a plurality of second abutments 334b, the plurality of first abutments 334a being fixed to the plurality of first posts 333a, respectively, and the plurality of second abutments 334b being fixed to the plurality of second posts 333b, respectively. Any two longitudinally adjacent first base stations 334a are respectively fixed at two ends of a first connecting rod 335 buried under the ground of the winch chamber 20, any two transversely opposite first base stations 334a are respectively fixed at two ends of a second connecting rod 336 buried under the ground of the winch chamber 20, and any two adjacent second base stations 334 are respectively fixed at two ends of a third connecting rod 337 buried under the ground of the winch chamber 20 and positioned above the second connecting rod 336.

The plurality of base stations 334 can be connected to form a unitary structure by the plurality of connecting rods 335,336,337 buried under the ground, and the overall strength of the bracket structure can be further improved. Further, in consideration of the large pressure borne by the second upright 333b, the second abutment 334b fixed thereto is easily depressed, and therefore, in the current implementation, the third connection bar 337 is disposed above the second connection bar 336. In this way, the second connecting bar 336 and the first abutment 334a will provide good support for the third connecting bar 337 and the second abutment 334b, avoiding sagging of the second abutment 334 b.

The term "according to" is based, at least in part, on. The term "one embodiment" means "a pair of embodiments"; the term "another embodiment" means "a pair of additional embodiments".

It should be understood that, although the terms "first" or "second," etc. may be used in this disclosure to describe various elements (e.g., a first column and a second column), these elements are not provided by these terms, which are merely used to distinguish one element from another element.
