Description

Technical Field

[0001] This invention relates to the field of mining machinery technology, and more specifically, to a support transport vehicle. Background Technology

[0002] Currently, the main method for retracting hydraulic supports in fully mechanized mining faces is as follows: first, a fixed winch device is used to pull the support to be transported out of the hydraulic support area; then, a shovel truck is used to transport the support position over a short distance to the transport channel for hydraulic support posture correction; finally, a support transport vehicle is used to complete the transport of the hydraulic support.

[0003] In existing technologies, support transport vehicles can only transport supports. When moving, they cannot exert maximum traction to move heavy supports of large tonnage, nor can they correct the posture of the supports. Therefore, they cannot independently complete the entire retraction process of hydraulic supports. Currently, the pulling, correction, and transporting of supports requires at least three heavy machinery units to complete. The retraction process for hydraulic supports is complex and has low transportation efficiency. Summary of the Invention

[0004] This invention provides a support transport vehicle to solve the problem of low efficiency in the retraction and transportation of hydraulic supports in the prior art.

[0005] This invention provides a bracket transport vehicle, comprising: a vehicle body having a placement cavity and an opening, the placement cavity being for placing a bracket, and the opening being located at the end of the vehicle body and communicating with the placement cavity; a hinge assembly disposed on the vehicle body, the hinge assembly having a hook and a hinge, the hook being used to drag the bracket and move the bracket into the placement cavity; and a support device disposed at the end of the vehicle body and located on the side of the vehicle body, the support device having a first support end and a second support end, the first support end being movable upward in a vertical direction, and the second support end being movable downward in a vertical direction, the support device having a fixed state and a clearance state. When the support device is in a fixed state, the first support end moves upward and abuts against the top of the tunnel, and the second support end moves downward and abuts against the ground. The first and second support ends cooperate to fix the vehicle body. When the support device is in a clearance state, the first support end is set away from the top of the tunnel, and the second support end is set away from the ground. The guide assembly is located at the end of the vehicle body and on the side of the vehicle body. The guide assembly has a fixed end and a guide end that are arranged opposite to each other. The fixed end is used to fix the guide assembly, and the guide end has a guide hole for the hook and hinge to pass through in order to guide the movement of the hook.

[0006] Furthermore, the support device includes: a housing; a first telescopic member disposed on the housing, with a first end fixed to the housing and a second end facing upward, forming a first support end; and a second telescopic member disposed on the housing, with a first end fixed to the housing and a second end facing downward, forming a second support end.

[0007] Furthermore, the guide assembly has an unfolded state and a retracted state that are set relative to each other. When the guide assembly is in the unfolded state, the guide end unfolds in a direction away from the fixed end, and the extension direction of the guide assembly is the same as the extension direction of the vehicle body. When the guide assembly is in the retracted state, the guide end moves in a direction closer to the fixed end.

[0008] Furthermore, the guide assembly includes a first connecting segment, a second connecting segment, and a third connecting segment connected in sequence. The first connecting segment is fixed to the housing, the second connecting segment is hinged to the first connecting segment, and the third connecting segment is hinged to the second connecting segment. The guide assembly has an inner side and an outer side that are relatively arranged along the width direction of the vehicle body. When the guide assembly switches from the unfolded state to the retracted state, the third connecting segment bends from the outer side of the guide assembly toward the direction of the second connecting segment.

[0009] Furthermore, a first connecting seat is provided on the housing, the first connecting seat is located outside the guide assembly, the guide assembly also includes: a connecting rod, the first end of the connecting rod is hinged to the second connecting segment, the end of the second connecting segment near the third connecting segment is also provided with a second connecting seat, the second end of the connecting rod can be selectively connected to the first connecting seat or the second connecting seat, when the guide assembly is in the unfolded state, the second end of the connecting rod is connected to the first connecting seat to restrict the rotation of the second connecting segment relative to the first connecting segment.

[0010] Furthermore, the support device and the guide assembly form an auxiliary assembly, and a set of auxiliary assemblies are respectively provided on both sides of the vehicle body along the width direction.

[0011] Furthermore, the bracket transport vehicle also includes a lifting assembly, which is mounted on the vehicle body and is used to lift the bracket located in the placement cavity.

[0012] Furthermore, the lifting assembly includes: a third telescopic member, the first end of which is hinged to the vehicle body; a swing member, the first end of which is hinged to the vehicle body, and the second end of which is hinged to the second end of the third telescopic member, wherein the third telescopic member drives the second end of the swing member to swing in the vertical direction; and a hook member, which is connected to the second end of the swing member and is used to hook onto the bracket, wherein the third telescopic member drives the bracket to lift and lower via the swing member and the hook member.

[0013] Furthermore, the support transport vehicle includes multiple lifting components, which are spaced apart along the periphery of the placement cavity.

[0014] Furthermore, the vehicle body includes a crossbeam and two fixed frames, which are spaced apart along the width of the vehicle body. The crossbeam is located at the end of the vehicle body and is connected to one end of each of the two fixed frames. An opening is located at the other end of the two fixed frames, and a placement cavity is formed between the crossbeam and the two fixed frames. A hinge assembly is mounted on the crossbeam.

[0015] By applying the technical solution of this invention, a support device is installed at the end of the vehicle body. When the support device is in an avoidance state, the first support end is away from the top of the tunnel, and the second support end is away from the ground, allowing the vehicle body to move. When the support device is in a fixed state, the first support end abuts against the top of the tunnel, and the second support end abuts against the ground. At this time, the first and second support ends cooperate to restrict the movement of the vehicle body, thereby fixing it in place. With this configuration, the support can be pulled and moved through the cooperation of the hinge assembly and the guide assembly. Furthermore, the support device prevents displacement of the vehicle body during the pulling of the support, maximizing the traction force of the hinge and quickly moving the support to the vicinity of the vehicle body. Subsequently, the position of the vehicle body relative to the support is adjusted, and the support is placed inside the vehicle body before transportation. Thus, only one transport vehicle is needed to complete the support retraction, eliminating the need for multiple mechanical devices and greatly improving the efficiency of support retraction and transportation.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figure 1 and Figure 2As shown, the present invention provides a bracket transport vehicle, comprising: a vehicle body 10, a hinge assembly 20, a support device 30, and a guide assembly 40. The vehicle body 10 has a placement cavity 11 and an opening 12. The placement cavity 11 is used to place the bracket, and the opening 12 is located at the end of the vehicle body 10 and communicates with the placement cavity 11. The hinge assembly 20 is disposed on the vehicle body 10 and has a hook 21 and a hinge 22. The hook 21 is used to drag the bracket and move it into the placement cavity 11. The support device 30 is located at the end of the vehicle body 10 and on the side of the vehicle body 10. The support device 30 has a first support end 31 and a second support end 32. The first support end 31 can move upward in the vertical direction, and the second support end 32 can move downward in the vertical direction. The support device 30 has a fixed state and a clearance state. When the support device 30 is in the fixed state, the first support end 31 moves upward and abuts against the top of the tunnel, and the second support end 32 moves downward and abuts against the ground. The first support end 31 and the second support end 32 cooperate to fix the vehicle body 10. When the support device 30 is in the clearance state, the first support end 31 is set away from the top of the tunnel, and the second support end 32 is set away from the ground. The guide assembly 40 is located at the end of the vehicle body 10 and on the side of the vehicle body 10. The guide assembly 40 has a fixed end 41 and a guide end 42 arranged opposite to each other. The fixed end 41 is used to fix the guide assembly, and the guide end 42 has a guide hole 421 for the hook 21 and the hinge 22 to pass through in order to guide the movement of the hook 21.

[0034] Applying the technical solution of this invention, a support device 30 is provided at the end of the vehicle body 10. When the support device 30 is in an avoidance state, the first support end 31 is away from the top of the tunnel, and the second support end 32 is away from the ground, allowing the vehicle body 10 to move. When the support device 30 is in a fixed state, the first support end 31 and the second support end 32 abut against the top of the tunnel and the ground, respectively. At this time, the first support end 31 and the second support end 32 cooperate to restrict the movement of the vehicle body 10, thereby fixing the vehicle body 10. With this configuration, the support can be pulled and moved through the cooperation of the hinge assembly 20 and the guide assembly 40. Furthermore, the support device 30 prevents the vehicle body 10 from shifting during the pulling of the support, thus maximizing the traction force of the hinge 22 and quickly pulling the support to the vicinity of the vehicle body 10. Subsequently, the position of the vehicle body 10 relative to the support is adjusted, and the support is placed inside the vehicle body 10 before transportation. In this way, the support can be retracted using only one transport vehicle, without the need for multiple mechanical equipment, which greatly improves the efficiency of support retraction and transportation.

[0035] The guide hole 421 is also equipped with a roller 422. This arrangement reduces the friction between the hinge 22 and the guide hole 421 when the bracket is pulled, thereby further improving the traction force of the hinge 22 and the pulling efficiency of the bracket. The roller 422 can be configured to rotate in the guide hole 421 and is arranged in a vertical direction.

[0036] like Figure 2 and Figure 3 As shown, the support device 30 includes a housing 33, a first telescopic member 34, and a second telescopic member 35. The first telescopic member 34 is mounted on the housing 33, with its first end fixed to the housing 33 and its second end facing upwards, forming a first support end 31 that abuts against the top of the tunnel. The second telescopic member 35 is mounted on the housing 33, with its first end fixed to the housing 33 and its second end facing downwards, forming a second support end 32 that abuts against the ground. By having the first telescopic member 34 and the second telescopic member 35 abut against the top of the tunnel and the ground, the vehicle body 10 is supported and limited, preventing displacement of the vehicle body 10 when the support is pulled, thus ensuring maximum traction.

[0037] Furthermore, the first telescopic member 34 and the second telescopic member 35 can be coaxially arranged or staggered; they can be simultaneously arranged inside the housing 33, or only one telescopic member can be arranged inside the housing 33. In this embodiment, the housing 33 also has a cover plate 333 and a fixing seat 334. The cover plate 333 is detachably connected to the housing 33 by bolts, facilitating the inspection and maintenance of the components inside the housing 33. The fixing seat 334 is used to fix the second telescopic member 35 to one side of the housing 33. The first telescopic member 34 includes a first telescopic rod 341 and a first telescopic cavity 342. The first telescopic cavity 342 is fixed inside the housing 33 by bolts. One end of the first telescopic rod 341 is movably arranged inside the first telescopic cavity 342, and the other end of the first telescopic rod 341 has a first support seat 343. The second telescopic member 35 includes a second telescopic rod 351 and a second telescopic cavity 352. The second telescopic cavity 352 is fixed in the fixed seat 334 by bolts. One end of the second telescopic rod 351 is movably disposed in the second telescopic cavity 352, and the other end of the second telescopic rod 351 has a second support seat 353. The above-mentioned structure is simple and easy to control. Moreover, the provision of the support seat increases the contact area between the first telescopic member 34 and the second telescopic member 35 and the top of the tunnel and the ground, thereby improving the limiting effect on the vehicle body 10. In this application, the specific form of the first telescopic member 34 and the second telescopic member 35 is not limited, and they can be cylinders, hydraulic cylinders, or electric cylinders.

[0038] like Figure 4 and Figure 5As shown, the guide assembly 40 has an unfolded state and a retracted state arranged opposite to each other. When the guide assembly 40 is in the unfolded state, the guide end 42 unfolds away from the fixed end 41, and the extension direction of the guide assembly 40 is the same as the extension direction of the vehicle body 10. When the guide assembly 40 is in the retracted state, the guide end 42 moves towards the fixed end 41. With the above arrangement, when the support needs to be pulled, the guide assembly 40 is controlled to be in the unfolded state, and when the pulling work of the support is completed, the guide assembly 40 is controlled to be in the retracted state. This can reduce the space occupied by the guide assembly 40 and also prevent the guide assembly 40 from scraping against other facilities in the roadway when the vehicle body 10 moves, thus avoiding damage to the guide assembly 40.

[0039] Specifically, the guide assembly 40 includes a first connecting segment 43, a second connecting segment 44, and a third connecting segment 45 connected in sequence. The first connecting segment 43 is fixed to the housing 33, the second connecting segment 44 is hinged to the first connecting segment 43, and the third connecting segment 45 is hinged to the second connecting segment 44. The guide assembly 40 has an inner side and an outer side that are relatively arranged along the width direction of the vehicle body 10. When the guide assembly 40 switches from the unfolded state to the retracted state, the third connecting segment 45 bends from the outer side of the guide assembly 40 toward the direction of the second connecting segment 44. This arrangement makes the relative rotation between the different connecting segments more flexible. When the hinge 22 pulls the bracket, the third connecting segment 45 can rotate relative to the second connecting segment 44, thereby preventing the second connecting segment 44 and the first connecting segment 43 from breaking during the pulling process of the hinge 22. Moreover, the above-mentioned structure is simple and easy to process and install. Preferably, the third connecting segment 45 is connected to the second connecting segment 44 by a hinge. In this way, the third connecting segment 45 can only be bent from the outside of the guide component 40 toward the second connecting segment 44. If the third connecting segment 45 is bent from the outside of the guide component 40 toward the inside, it is easy to bring the third connecting segment 45 into a bent state when the bracket is pulled, which will reduce the pulling efficiency of the bracket. With the hinge, the third connecting segment 45 can remain in an unfolded state when the bracket is pulled, ensuring the smoothness of the bracket pulling.

[0040] Furthermore, the housing 33 is provided with a first connecting lug 335, and the end of the third connecting segment 45 away from the second connecting segment 44 is provided with a second connecting lug 336 that cooperates with it. When the guide assembly 40 switches from the extended state to the retracted state, the third connecting segment 45 bends from the outside of the guide assembly 40 toward the second connecting segment 44, and then the second connecting lug 336 is connected to the first connecting lug 335 by a pin or screw to prevent the guide assembly 40 from swinging in the retracted state. The housing 33 is also provided with a cable hole on the side near the vehicle body 10 for passing through the cable that provides driving force for the first telescopic member 34 and the second telescopic member 35.

[0041] In this application, a first connecting seat 331 is provided on the housing 33, located outside the guide assembly 40. The guide assembly 40 also includes a connecting rod 46, the first end of which is hinged to a second connecting segment 44. A second connecting seat 332 is also provided at the end of the second connecting segment 44 near the third connecting segment 45. The second end of the connecting rod 46 can be selectively connected to either the first connecting seat 331 or the second connecting seat 332. When the guide assembly 40 is in the extended state, the second end of the connecting rod 46 is connected to the first connecting seat 331 to restrict the rotation of the second connecting segment 44 relative to the first connecting segment 43. When the guide assembly 40 is in the retracted state, the second end of the connecting rod 46 is connected to the second connecting seat 332, allowing the second connecting segment 44 to rotate relative to the first connecting segment 43. With this configuration, the guide assembly 40 can be quickly switched between the extended and retracted states through the cooperation of the connecting rod 46 with either the first connecting seat 331 or the second connecting seat 332. Furthermore, when the guide component 40 is in the unfolded state, it can not only support the guide component 40 to prevent it from being damaged or broken, but also ensure the stability of the guide component 40 in supporting the hinge 22 during the pull-out process of the bracket, thereby improving the pull-out effect of the hinge 22 on the bracket.

[0042] Furthermore, the support device 30 and the guide assembly 40 form an auxiliary assembly 50, and a set of auxiliary assemblies 50 is respectively provided on both sides of the vehicle body 10 along the width direction. With the above arrangement, the support on which side of the vehicle body 10 needs to be retracted can be selected and the corresponding auxiliary assembly 50 can be opened, which improves the applicability and flexibility of the support transport vehicle operation.

[0043] The support transport vehicle also includes a lifting assembly 60, which is mounted on the vehicle body 10. The lifting assembly 60 is used to lift the support located in the placement cavity 11. With the above configuration, the support can be lifted off the ground for transport, eliminating the need for a base plate inside the vehicle body 10 to place the support, thus simplifying the structure of the transport vehicle.

[0044] like Figure 6As shown, the lifting assembly 60 includes a third telescopic member 61, the first end of which is hinged to the vehicle body 10. The first end of a swing member 62 is hinged to the vehicle body 10, and the second end of the swing member 62 is hinged to the second end of the third telescopic member 61. The third telescopic member 61 drives the second end of the swing member 62 to swing vertically. A hook member 63 is connected to the second end of the swing member 62 and is used to hook onto a bracket. The third telescopic member 61 drives the bracket to rise and fall through the swing member 62 and the hook member 63. The lifting assembly 60 also includes a chain 64 and a sprocket 65, with the sprocket 65 connected to the swing member 62 via a pin. Thus, by controlling the extension and retraction of the third telescopic member 61, the second end of the swing member 62 can be driven to swing left and right vertically, thereby causing the sprocket 65 to rotate counterclockwise and clockwise, thus extending and shortening the chain 64, and consequently raising and lowering the bracket.

[0045] Specifically, the support transport vehicle includes multiple lifting components 60, which are spaced apart along the periphery of the placement cavity 11. This arrangement allows for simultaneous circumferential engagement of the support, ensuring its stability during lifting and transportation. Preferably, the multiple lifting components 60 are symmetrically arranged around the periphery of the placement cavity 11 to prevent tilting or tipping during lifting or transportation.

[0046] like Figure 1 As shown, the support transport vehicle also includes a drive unit 70 for driving the vehicle body 10 to move. The vehicle body 10 includes a crossbeam 13 and two fixed frames 14, which are spaced apart along the width of the vehicle body 10. The crossbeam 13 is located at the end of the vehicle body 10 and is connected to one end of each of the two fixed frames 14, with openings at the other ends of the two fixed frames 14. A placement cavity 11 is formed between the crossbeam 13 and the two fixed frames 14. A hinge assembly 20 is mounted on the crossbeam 13. By placing the hinge assembly 20 at the end of the vehicle body 10, the support can be pulled and moved without the need for a separate winch, simplifying the retraction operation and process.

[0047] Specifically, when using the support transport vehicle provided in this application to retract the support, the operating steps are as follows:

[0048] S1: Stent removal.

[0049] 1. The drive device 70 controls the movement of the support transport vehicle, so that the opening of the support transport vehicle is placed in front of the support. The first telescopic rod 341 and the second telescopic rod 351 are controlled to extend from the first telescopic cavity 342 and the second telescopic cavity 352 respectively, so that the first support seat 343 abuts against the top surface of the roadway and the second support seat 353 abuts against the ground of the roadway.

[0050] 2. Pull out the pin or screw to make the second connecting section 44 and the third connecting section 45 float. Rotate the second connecting section 44 and the third connecting section 45 to make the guide assembly 40 unfold. Connect one end of the connecting rod 46 to the first connecting seat 331 to lock the second connecting section 44.

[0051] 3. By controlling the hinge assembly 20, the hinge 22 extends, and the hinge 22 and hook 21 bypass the guide hole 421 of the third connecting section 45 and connect to the bracket to be transported.

[0052] 4. By controlling the hinge assembly 20 to retract the hinge 22, the bracket is pulled out of the bracket support area;

[0053] S2: Bracket posture correction.

[0054] 1. One end of the connecting rod 46 is connected to the second connecting seat 332, so that the guide assembly 40 is in the retracted state, and at the same time, the first telescopic rod 341 and the second telescopic rod 351 are retracted, so that the first support seat 343 leaves the top surface of the roadway and the second support seat 353 leaves the ground.

[0055] 2. The drive unit 70 controls the movement of the support transport vehicle, so that the support is parallel to the side of the vehicle body 10;

[0056] S3: Support transport.

[0057] 1. The vehicle is driven by the drive device 70 to move and the bracket is placed inside the placement cavity 11.

[0058] 2. The third telescopic component 61 of the control lifting assembly 60 is retracted to lift the bracket off the ground, and the bracket is transported to the designated location by the drive device 70.
