Description

Technical Field

[0001] The present invention relates to the technical field of mine transportation, and in particular, to a transportation device. Background Art

[0002] A hydraulic support is a structure for controlling the mine pressure in a coal mining face. The mine pressure in the mining face acts on the hydraulic support in the form of external load.

[0003] In the related art, when transporting a hydraulic support, the hydraulic support needs to be hoisted onto a special transport vehicle first. After the transport vehicle transports the hydraulic support to a designated location, a mine hydraulic frame lifting device, a hydraulic support transfer device, a folding hydraulic support installation forklift, etc. are used to unload the hydraulic support from the transport vehicle. However, the height and width of the roadway in the coal mine shaft are limited, resulting in that large engineering cranes such as mine hydraulic frame lifting devices, hydraulic support transfer devices, and folding hydraulic support installation forklifts cannot be used in the roadway. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems in the related art to some extent. For this purpose, an embodiment of the present invention provides a transportation device, which can realize the transportation of a hydraulic support in the roadway of a coal mine shaft and reduce the construction cost.

[0005] The transportation device according to the embodiment of the present invention includes: a load-bearing frame, where there are at least two load-bearing frames, the at least two load-bearing frames are arranged at intervals along a first direction, and at least a part of the load-bearing frame is adapted to be connected to the hydraulic support; the load-bearing frame includes a main board, a first mounting member, a first side board, and a second side board, the first mounting member is arranged on the main board, the first side board and the second side board are arranged at intervals along the first direction on the main board and are located at the lower end of the main board, and the first side board, the second side board, and the first mounting member are located on the same side of the main board; wheels, where there are at least two wheels, the at least two wheels are provided in one-to-one correspondence with the at least two load-bearing frames, the wheels are arranged between the first side board and the second side board and are rotatable relative to the first side board and the second side board, and the wheels are adapted to abut against a track; jacks, where there are at least two jacks, the at least two jacks are provided in one-to-one correspondence with the at least two load-bearing frames, the lower part of the jack is connected to the first mounting member, and the upper part of the jack is connected to the hydraulic support so that the jack can drive the hydraulic support to move up and down.

[0006] In the transportation device according to the embodiment of the present invention, the wheels run on the track and drive the load-bearing frame to also run on the track. The lower part of the jack is connected to the first mounting member, and the upper part of the jack is connected to the hydraulic support. When the jack moves in the up and down direction, it can drive the hydraulic support to also move in the up and down direction.

Detailed implementation manners

[0023] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] As Figures 1-6 shown, the transportation device according to an embodiment of the present invention includes a load-bearing frame 1, wheels 2 and a jack 3. There are at least two load-bearing frames 1, and the at least two load-bearing frames 1 are arranged at intervals in the first direction, and at least a part of the load-bearing frame 1 is adapted to be connected to the hydraulic support 10. The load-bearing frame 1 includes a main board 11, a first mounting member 12, a first side plate 13 and a second side plate 14. The first mounting member 12 is provided on the main board 11. The first side plate 13 and the second side plate 14 are arranged at intervals in the first direction on the main board 11 and are located at the lower end of the main board 11. The first side plate 13, the second side plate 14 and the first mounting member 12 are located on the same side of the main board 11.

[0025] Specifically, as Figure 3 shown, the first side plate 13, the second side plate 14 and the first mounting member 12 are all located in front of the support plate 15. Openings 131 are provided at the lower parts of the first side plate 13 and the second side plate 14. Clamping plates 18 are provided at the openings 131. The wheels 2 are arranged between the first side plate 13 and the second side plate 14 and are connected to the first side plate 13 and the second side plate 14 through the clamping plates 18.

[0026] As Figure 4 shown, the first mounting member 12 includes two first mounting plates 121. The two first mounting plates 121 are arranged oppositely. The two first mounting plates 121 are arranged at intervals in the first direction on the main board 11, and the two first mounting plates 121 are located between the first side plate 13 and the second side plate 14. First mounting holes 122 are provided on the first mounting plates 121.

[0027] As Figure 1As shown in the figure, there are at least two wheels 2. The at least two wheels 2 are arranged in one-to-one correspondence with at least two load-bearing frames 1. The wheels 2 are arranged between the first side plate 13 and the second side plate 14 and are rotatable relative to the first side plate 13 and the second side plate 14. The wheels 2 are adapted to abut against the track. There are at least two jacks 3. The at least two jacks 3 are arranged in one-to-one correspondence with at least two load-bearing frames 1. The lower part of the jack 3 is connected to the first mounting member 12, and the upper part of the jack 3 is connected to the hydraulic support 10 so that the jack 3 can drive the hydraulic support 10 to move up and down.

[0028] Specifically, as Figure 3 shown, the jack 3 includes a cylinder barrel 31 and a piston rod 32. The piston rod 32 is arranged inside the cylinder barrel 31 and can expand and contract relative to the cylinder barrel 31 along the extension direction of the cylinder barrel 31. A connecting block 33 is provided at the lower part of the cylinder barrel 31. The connecting block 33 is connected to the first mounting member 12 so that the cylinder barrel 31 is connected to the main board 11 of the load-bearing frame 1, and the upper part of the piston rod 32 is connected to the hydraulic support 10.

[0029] In the transportation device according to the embodiment of the present invention, the wheels 2 run on the track and drive the load-bearing frame 1 to also run on the track. The lower part of the jack 3 is connected to the first mounting member 12, and the upper part of the jack 3 is connected to the hydraulic support 10. When the jack 3 moves in the up and down direction, it can drive the hydraulic support 10 to also move in the up and down direction. Compared with the operation process of moving the traditional hydraulic support 10 to a new face, the process of unloading the hydraulic support 10, transporting the hydraulic support 10 over a long distance, and loading the hydraulic support 10 is omitted. The complex work of moving the hydraulic support 10 to a new face is changed into a relatively simple transportation method. Therefore, the transportation device according to the embodiment of the present invention can not only move the hydraulic support 10 along the track in the roadway, but also move the hydraulic support 10 in the up and down direction under the action of the jack 3, so that the handling process during the installation or withdrawal of the hydraulic support 10 is simple, and the construction cost is reduced.

[0030] In some embodiments, as Figure 1 shown, the load-bearing frame 1 further includes a support plate 15. The support plate 15 is arranged on the main board 11. The support plate 15 is located above the first mounting member 12. The support plate 15 abuts against the upper parts of the first side plate 13 and the second side plate 14. A through hole 151 is formed in the support plate 15. The lower part of the jack 3 passes through the through hole 151 and is connected to the first mounting member 12.

[0031] Specifically, as Figure 3 and Figure 4As shown, the support plate 15 is arranged in front of the main board 11, and the bottom surface of the support plate 15 is connected to the upper part of the first side plate 13 and the upper part of the second side plate 14. The through hole 151 is located on the side surface of the support plate 15 close to the main board 11. The connecting block 33 at the lower part of the cylinder 31 passes through the through hole 151 and is located between the two first mounting plates 121, and screws are penetrated on the connecting block 33. The screws pass through the first mounting hole 122, the connecting block 33 and the first mounting hole 122 in sequence to connect the connecting block 33 with the two first mounting plates 121, so that the jack 3 is arranged on the load-bearing frame 1, and the upper part of the piston rod 32 extends upward in the up-down direction and is connected to the hydraulic support 10. The bottom surface of the cylinder 31 is against the top surface of the support plate 15. When the piston rod 32 drives the hydraulic support 10 to move up and down in the up-down direction, the stability of the jack 3 can be ensured when it is used.

[0032] In some embodiments, Figure 2 As shown, the load-bearing frame 1 also includes a first rib plate 16 and a second rib plate 17, which are arranged on the main board 11 at intervals along the first direction, and at least parts of the first rib plate 16 and the second rib plate 17 are connected to the top of the support plate 15, and the jack 3 is located between the first rib plate 16 and the second rib plate 17.

[0033] Specifically, Figure 3 As shown, the first rib plate 16 and the second rib plate 17 are both located in front of the main board 11, and the jack 3 is located between the first rib plate 16 and the second rib plate 17, so that the first rib plate 16 and the second rib plate 17 can play a guiding role, ensuring that the jack 3 can remain stable when jacking up the hydraulic support 10, thereby ensuring the stability of the hydraulic support 10 on the transportation device of the embodiment of the present invention.

[0034] In some embodiments, the transport device further comprises a connecting member 4, a second mounting member 5 and a stop member 6. The connecting member 4 is disposed on the side of the main board 11 away from the first mounting member 12 (eg Figure 1 The connecting member 4 is connected to the main board 11 and can move in the up and down direction relative to the main board 11. One end of the connecting member 4 (as shown in FIG. Figure 1 The lower end of the connecting member 4 shown in FIG. 1 is connected to the hydraulic support 10, and the other end of the connecting member 4 (as shown in FIG. Figure 1 The upper end of the connecting member 4 shown in the figure is connected to the top of the jack 3, and the jack 3 drives the connecting member 4 to move in the up and down direction. The second mounting member 5 is arranged at the upper end of the connecting member 4, and the upper part of the jack 3 is connected to the second mounting member 5. The limiting member 6 is arranged at the upper end of the connecting member 4 and is located below the second mounting member 5. The limiting member 6 is suitable for contacting with the top of the jack 3 and keeping the jack 3 in an extended state.

[0035] Specifically, Figure 3As shown, the connecting member 4 is provided at the rear of the main board 11 and can move relative to the main board 11 in the up and down direction. The lower part at the rear of the connecting member 4 is connected to the hydraulic support 10. The second mounting member 5 is located at the upper part in front of the connecting member 4. The second mounting member 5 includes two relatively arranged second mounting plates 51. The two second mounting plates 51 are arranged at intervals in the left and right direction at the upper part in front of the main board 11. Second mounting holes 52 are formed in the second mounting plates 51. The upper part of the piston rod 32 is located between the two second mounting plates 51, and the upper part of the piston rod 32 is connected to the second mounting plate 51 by screws, so that when the piston rod 32 moves up and down, it can drive the connecting member 4 to move up and down relative to the main board 11, thereby driving the hydraulic support 10 to move up and down. Thus, when the transportation device of the embodiment of the present invention drives the hydraulic support 10 to move in the up and down direction, the operation is simple and convenient.

[0036] As Figure 1 shown, the track includes a left track and a right track. The limiting member 6 includes a second rotating shaft 61 and a limiting plate 62. The second rotating shaft 61 is provided at the upper part on the front side of the connecting member 4 and extends in the up and down direction. The second rotating shaft 61 is located outside the second mounting member 5. The limiting plate 62 is located below the second mounting member 5. One end of the limiting plate 62 is provided on the second rotating shaft 61 and the limiting plate 62 can rotate around the central axis of the second rotating shaft 61.

[0037] It should be noted that, as Figure 1 shown, the "outside" in the outside of the second mounting member 5 is based on the center of the hydraulic support 10. The direction away from the center of the hydraulic support 10 is outward, and the direction towards the center of the hydraulic support 10 is inward. Specifically, as Figure 1 shown, the outside of the left second mounting member 5 is the side where the left second mounting member 5 is away from the right second mounting member 5, that is, the left side of the left second mounting member 5; the outside of the right second mounting member 5 is the side where the right second mounting member 5 is away from the left second mounting member 5, that is, the right side of the right second mounting member 5.

[0038] As Figures 1-3As shown, the transportation device further includes a control valve (not shown), and the jack 3 is connected to the control valve. The working principle of the transportation device according to the embodiment of the present invention is as follows: Operate the control valve to extend the piston rod 32 of the jack 3 upward. At least two jacks 3 will synchronously push the connecting member 4 upward with the wheel 2 as the fulcrum. The connecting member 4 will lift the hydraulic support 10. Twist the limit plate 62 so that the limit plate 62 is located between the top surface of the cylinder barrel 31 of the jack 3 and the bottom surface of the second mounting member 5. Operate the reversing valve to move the piston rod 32 of the jack 3 downward. The bottom surface of the limit plate 62 abuts against the top surface of the cylinder barrel 31 of the jack 3 to stop the connecting member 4 from falling, so that the hydraulic support 10 stops falling. At this time, there is a specified distance between the bottom surface of the hydraulic support 10 and the top surface of the track. Connect a towing rope (not shown) to the hydraulic support 10 to pull the hydraulic support 10 to move through the towing rope. After the hydraulic support 10 reaches the specified position, operate the reversing valve to move the piston rod 32 of the jack 3 upward, then twist the limit plate 62 to the non-support position, and then operate the reversing valve to move the piston rod 32 of the jack 3 downward. The hydraulic support 10 descends to the top surface of the track, thus completing the entire working process of lifting, transporting, and descending the hydraulic support 10.

[0039] Therefore, the transportation device according to the embodiment of the present invention is easy to operate when transporting the hydraulic support 10 in the roadway. When the piston rod 32 is in the extended state, the distance between the bottom surface of the hydraulic support 10 and the top surface of the track tends to be the closest, so that the center of gravity of the hydraulic support 10 is reduced, and the swing amount of the hydraulic support 10 during driving on the track can be reduced, thereby reducing the potential safety hazards during the transportation of the hydraulic support 10 in the roadway. In addition, during the process of the hydraulic support 10 landing or being lifted, the process of lifting it off or onto the transport vehicle with a lifting device is avoided, thereby eliminating the potential safety hazards existing during the lifting process and saving costs.

[0040] In some embodiments, as Figure 5 shown, the transportation device further includes a slideway 7. The slideway 7 is provided on the side of the main board 11 facing away from the first mounting member 12 (such as Figure 1 the back of the main board 11 shown). The slideway 7 extends in the up and down direction. The connecting member 4 is arranged in the slideway 7 and can slide in the slideway 7.

[0041] Specifically, as Figure 5 shown, the slideway 7 is provided on the back of the main board 11 through bolts, and the slideway 7 extends in the up and down direction. The connecting member 4 is slidably installed in the slideway 7 and is not easily detached from the slideway 7 in the front and back directions. When the piston rod 32 of the jack 3 moves in the up and down direction, the piston rod 32 drives the connecting member 4 to move up and down relative to the main board 11. Thus, the installation method of the connecting member 4 on the main board 11 is simple and cost-saving.

[0042] In some embodiments, as Figure 5As shown, the transportation device further includes a mounting member 8, and the mounting member 8 is located on the side of the connecting member 4 facing away from the second mounting member 5 (such as Figure 1 behind the connecting member 4 shown), one end of the mounting member 8 is connected to the connecting member 4, and the other end of the mounting member 8 is connected to the hydraulic support 10.

[0043] Specifically, the mounting member 8 includes a first connecting section 81 and a second connecting section 82. One end of the first connecting section 81 is connected to the lower end of the rear surface of the connecting member 4, and the other end of the first connecting section 81 is connected to the second connecting section 82.

[0044] Such as Figure 5 and Figure 6 shown, the hydraulic support 10 includes a main body 101 and side plates 102. There are two side plates 102, and the two side plates 102 are respectively arranged in front of and behind the main body 101. Through holes 103 are formed at both ends of the side plates 102. The second connecting section 82 passes through the through holes 103 to connect the mounting member 8 to the side plates 102, so as to connect the mounting member 8 to the hydraulic support 10. Thus, the connection method between the transportation device and the hydraulic pressure in the embodiment of the present invention is simple and convenient for disassembly.

[0045] In some embodiments, such as Figure 5 shown, the transportation device further includes a swing assembly 9. The swing assembly 9 is arranged on one side of the main board 11. The swing assembly 9 can rotate around the up-down direction, and the swing assembly 9 can abut against the hydraulic support 10.

[0046] Specifically, the swing assembly 9 rotates around the up-down direction to the rear of the connecting member 4, and the swing assembly 9 abuts against the top surface of the side plate 102 of the hydraulic support 10. When the jack 3 drives the hydraulic support 10 to move in the up-down direction, the stability of the hydraulic support 10 during the movement can be ensured.

[0047] In some embodiments, such as Figure 5 shown, the swing assembly 9 includes a first rotating shaft 91 and a swinging member 92. The first rotating shaft 91 is arranged on one side of the main board 11, and the first rotating shaft 91 extends along the up-down direction. One end of the swinging member 92 is connected to the first rotating shaft 91, and the swinging member 92 can rotate around the central axis of the first rotating shaft 91. When the swinging member 92 rotates to the side of the main board 11 facing away from the first mounting member 12, the swinging member 92 abuts against the hydraulic support 10, and the connecting member 4 is located between the main board 11 and the swinging member 92.

[0048] Specifically, as Figure 5 shown, the swing assembly 9 further includes a setscrew 93. The setscrew 93 is arranged on the swinging member 92. When the swinging member 92 rotates along the central axis of the first rotating shaft 91 to the rear of the connecting member 4, the bottom surface of the setscrew 93 abuts against the top surface of the side plate 102 of the hydraulic support 10, so as to make the movement of the jack 3 driving the hydraulic support 10 in the up-down direction more stable.

[0049] In some embodiments, at least two wheels 2 are divided into multiple groups. Each group of wheels 2 includes two wheels arranged at intervals in a first direction, and the multiple groups of wheels 2 are arranged at intervals in a second direction. The second direction is orthogonal to the first direction. At least two load-bearing frames 1 are divided into multiple groups. Each group of load-bearing frames 1 includes two load-bearing frames arranged at intervals in the first direction, and the multiple groups of load-bearing frames 1 are arranged at intervals in the second direction. The load-bearing frames 1 and the wheels 2 are arranged in one-to-one correspondence.

[0050] Specifically, as Figure 1 shown, there are four wheels 2. The four wheels 2 are evenly divided into two groups. The two groups of wheels 2 are arranged at intervals in the front-rear direction. Each group of wheels 2 includes two wheels 2, and the two wheels 2 are arranged at intervals in the left-right direction. There are also four load-bearing frames 1. The four load-bearing frames 1 are evenly divided into two groups. The two groups of load-bearing frames 1 are arranged at intervals in the front-rear direction. Each group of load-bearing frames 1 includes two load-bearing frames 1, and the two load-bearing frames 1 are arranged at intervals in the left-right direction. Moreover, the load-bearing frames 1 and the wheels 2 are arranged in one-to-one correspondence. Thus, when the transportation device according to the embodiment of the present invention runs on the track, it is more stable.

[0051] In some embodiments, at least two jacks 3 are divided into multiple groups. Each group of jacks 3 includes two jacks arranged at intervals in a first direction, and the multiple groups of jacks 3 are arranged at intervals in a second direction. The jacks 3 and the load-bearing frames 1 are arranged in one-to-one correspondence.

[0052] Specifically, as Figure 1 shown, there are four jacks 3. The four jacks 3 are evenly divided into two groups. The two groups of jacks 3 are arranged at intervals in the front-rear direction. Each group of jacks 3 includes two jacks 3, and the two jacks 3 are arranged at intervals in the left-right direction. The jacks 3 and the load-bearing frames 1 are arranged in one-to-one correspondence. Thus, when the transportation device according to the embodiment of the present invention drives the hydraulic support 10 to move up and down through the jacks 3, it is more stable and safe.
