Abstract
Description
Technical Field
[0001] This utility model relates to the field of fully mechanized hydraulic support technology, specifically a fully mechanized hydraulic support transfer device. Background Technology
[0002] A fully mechanized hydraulic support is a support device used in fully mechanized mining faces. It utilizes hydraulic energy to support, protect, and control the working face. Its main function is to provide support in fully mechanized mining faces, prevent face collapse, and ensure the safety of coal mining operations. At the same time, it can also control the shape and size of the working face to ensure the normal operation of the coal mining machine.
[0003] Due to the large weight and size of fully mechanized hydraulic supports, and the limitations imposed by existing mine conditions, it is difficult to transport them as a whole within the mine. Current technology typically involves disassembling them into modules such as the base, top beam assembly, front beam assembly, main column, and rear connecting rod before transport. These modules are then categorized and placed on a transfer vehicle, secured with ropes, and finally transported using a winch. However, because operators rely solely on visual judgment to determine the module's placement on the transfer vehicle, it is impossible to ensure the module's center of gravity is in the correct position. This leads to decreased stability of the transfer vehicle during mine transport, especially on sloping sections, where the module may slide downwards relative to the transfer vehicle, causing a further shift in its center of gravity and increasing the risk of derailment of both the module and the transfer vehicle. Utility Model Content
[0004] To address the problem that existing technologies rely solely on visual judgment to determine the placement of modules on the transport vehicle, making it impossible to ensure the module's center of gravity is in the correct position, this invention provides a fully mechanized hydraulic support transport device. This device ensures that the placement of modules can be determined according to the indication of the indicator slot, guaranteeing the center of gravity is in the correct position and enhancing the stability of the transport device.
[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a fully mechanized hydraulic support transfer device, including a support base for carrying the disassembled fully mechanized hydraulic support, two opposite indicator slots are opened on the support base, and the placement position can be determined based on the indicator slots when the disassembled fully mechanized hydraulic support is placed on the support base. Several wheels and multiple support plates are provided at the bottom of the support base. Two opposite upright plates are provided on the support base along its traveling direction. Both the support plates and the upright plates extend towards the lower side of the support base, and there is a gap between the support plates and the upright plates and the ground.
[0006] As a further optimization of the fully mechanized hydraulic support transfer device of the utility model: the support base includes a bearing plate and a base plate distributed vertically, the bearing plate and the base plate are connected by a plurality of first bolts, the first bolts are fastened by first nuts, the indicator groove is opened on the bearing plate, and the wheel, the support plate and the upright plate are all set on the base plate.
[0007] As a further optimization of the fully mechanized hydraulic support transfer device of the utility model: the indicator groove passes through one side of the bearing plate, and the extension direction of the indicator groove is perpendicular to the travel direction of the support seat. Several liner blocks are slidably arranged in the indicator groove, and a baffle for preventing the liner blocks from falling off is provided at the through end of the indicator groove. The baffle is fixedly connected to the bearing plate by a second bolt.
[0008] As a further optimization of the fully mechanized hydraulic support transfer device of the utility model: the surface of the liner extending out of the indicator groove is provided with a downwardly concave arc surface.
[0009] As a further optimization of the fully mechanized hydraulic support transfer device of the utility model: the extension direction of the indicator groove is parallel to the travel direction of the support base, and several liner blocks are slidably arranged in the indicator groove.
[0010] As a further optimization of the fully mechanized hydraulic support transfer device of the utility model: the portion of the liner block located outside the indicator groove is inclined toward the periphery of the bearing plate.
[0011] As a further optimization of the fully mechanized hydraulic support transfer device of the utility model: two rectangular grooves are provided between the two indicator grooves, and the extension direction of the grooves is parallel to the travel direction of the support.
[0012] As a further optimization of the utility model of a fully mechanized hydraulic support transfer device: the support base is provided with multiple third bolts, which limit the disassembled fully mechanized hydraulic support, and the support base is provided with mounting screw holes corresponding to the third bolts one by one.
[0013] As a further optimization of the fully mechanized hydraulic support transfer device of the utility model: the support base is detachably connected to a rope for binding and fixing the disassembled fully mechanized hydraulic support to the support base, and the support base is provided with multiple through holes corresponding to the rope.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1) This utility model provides a support base for supporting the disassembled fully mechanized hydraulic support. The support base has two opposing indicator slots. When the disassembled fully mechanized hydraulic support is placed on the support base, the placement position can be determined based on the indicator slots. The placement position of the disassembled fully mechanized hydraulic support can be determined according to the indication of the indicator slots, ensuring that the center of gravity of the disassembled fully mechanized hydraulic support is in a suitable position and enhancing the stability of the transfer device.
[0016] 2) The bottom of the support base is equipped with several wheels and multiple support plates. The support base has two opposing upright plates along its direction of travel. Both the support plates and the upright plates extend downwards and to the side of the support base.

Detailed Implementation
[0023] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of this utility model should be understood as prior art known or should be known by those skilled in the art, such as the specific structure of the fully mechanized hydraulic support, the structure of the underground conveying track, and the cooperation between the wheel 8 and the underground conveying track.
[0024] Example 1
[0025] A hydraulic support transfer device for fully mechanized mining, such as Figure 1 and Figure 2As shown, the system includes a support base 1 for supporting the disassembled fully mechanized hydraulic support. The support base 1 has two opposing indicator slots 2, which allow the disassembled fully mechanized hydraulic support to be placed on the support base 1 to determine its placement position based on the indicator slots 2. The bottom of the support base 1 is provided with several wheels 8 and multiple support plates 14. The support base 1 has two opposing upright plates 13 along its direction of travel. Both the support plates 14 and the upright plates 13 extend downward toward the side of the support base 1, and both the support plates 14 and the upright plates 13 have a gap between them and the ground.
[0026] The support base 1 is numbered in advance. After disassembling the fully mechanized hydraulic support, the components of the disassembled hydraulic support are classified and placed on the support base 1 based on the numbering to avoid confusion among the disassembled hydraulic supports. In this embodiment, the indicator groove 2 is set as a strip, and the wheel 8 cooperates with the underground conveying track. When placing the disassembled hydraulic support, the operator determines the placement position of the disassembled hydraulic support by the position of the indicator groove 2, thereby avoiding the risk of derailment between the subsequent transfer device and the disassembled hydraulic support due to excessive deviation of the center of gravity from the appropriate position.
[0027] To further prevent the transfer device and the disassembled fully mechanized hydraulic support from tipping over, multiple support plates 14 are installed at the bottom of the support base 1. Two opposing vertical plates 13 are also installed along the direction of travel of the support base 1. Both the support plates 14 and the vertical plates 13 extend downwards towards the side of the support base 1, and there is a gap between them and the ground. If the support base 1 tipps over, the vertical plates 13, or a portion of the support plates 14, will contact the ground, providing some support to the support base 1 and preventing it from tipping over. Furthermore, because there is a gap between the support plates 14 and the vertical plates 13 and the ground, their installation will not interfere with the normal transportation of the disassembled fully mechanized hydraulic support.
[0028] The above are the basic embodiments of this utility model. Further improvements, optimizations, and limitations can be made based on the above to obtain the following embodiments:
[0029] Example 2
[0030] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 3 and Figure 4 As shown, to facilitate the processing of the support base 1, the support base 1 includes a bearing plate 5 and a base plate 4 distributed vertically. The bearing plate 5 and the base plate 4 are connected by multiple first bolts 17, and the first bolts 17 are fastened by first nuts 18. The indicator groove 2 is formed on the bearing plate 5, and the wheel 8, the support plate 14, and the upright plate 13 are all set on the base plate 4.
[0031] Example 3
[0032] This embodiment is an improvement on embodiment 2. Its main structure is the same as that of embodiment 2, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 1 As shown, in this embodiment, both the support plate 5 and the base plate 4 are rectangular, with their lengths parallel to their travel direction. An indicator groove 2 extends through one side of the support plate 5, and its extension direction is perpendicular to the travel direction of the support base 1. The disassembled fully mechanized hydraulic support is placed on the support plate 5 according to the two indicator grooves 2. Since the disassembled fully mechanized hydraulic support contains large columns, several liner blocks 3 are slidably arranged inside the indicator groove 2 to facilitate placement of the large columns on the support plate 5. When the large columns are stacked on the support plate 5, they rest on and contact the liner blocks 3, resulting in better support of the support plate 5 against the large columns. If other components need to be placed, the liner blocks 3 can be removed from the indicator groove 2, leaving more space. A baffle 6 is provided at the through end of the indicator groove 2 to prevent the liner blocks 3 from falling off. The baffle 6 is fixedly connected to the support plate 5 by a second bolt 7. To better support the large columns, the surface of the liner blocks 3 extending out of the indicator groove 2 has a downwardly concave arc-shaped surface. The concave arc-shaped surface on both sides limits the movement of the main column, improving the stability of the support for the main column.
[0033] Example 4
[0034] like Figure 2 As shown, in this embodiment, both the bearing plate 5 and the base plate 4 are rectangular, and their length directions are parallel to their travel direction. The extension direction of the indicator groove 2 is parallel to the travel direction of the support base 1. Since there is a large column in the disassembled fully mechanized hydraulic support, several liner blocks 3 are slidably arranged in the indicator groove 2 to facilitate the placement of the large column. The portion of the liner block 3 extending out of the indicator groove 2 can limit the movement of the large column.
[0035] Example 5
[0036] This embodiment is an improvement on embodiment 4. Its main structure is the same as embodiment 4, but the improvement lies in the following: the liner blocks 3 in the two indicator slots 2 face each other, forming a receiving area for the large column. The large column is placed within this area, and the liner blocks 3 limit its position, preventing instability when placed on the support plate 5. To provide a larger receiving area for the large column, the portion of the liner block 3 located outside the indicator slots 2 is inclined towards the periphery of the support plate 5.
[0037] Example 6
[0038] This embodiment is an improvement on embodiment 4. Its main structure is the same as embodiment 4, but the improvement lies in the following: to further increase the stability of the large column when placed on the support plate 5, two rectangular grooves 15 are provided between the two indicator slots 2. The extending direction of the grooves 15 is parallel to the traveling direction of the support base 1. The grooves 15 can limit the movement of the large column.
[0039] Example 7
[0040] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 1 and Figure 2 As shown, the support base 1 is equipped with multiple third bolts, which limit the movement of the disassembled fully mechanized hydraulic support. The support base 1 has mounting screw holes 9 corresponding to the third bolts. When the disassembled fully mechanized hydraulic support is placed on the bearing plate 5, the third bolts can limit its movement, preventing the disassembled fully mechanized hydraulic support from shifting on the bearing plate 5.
[0041] The support base 1 is detachably connected to ropes for binding and fixing the disassembled fully mechanized hydraulic support to the support base 1, and the support base 1 has multiple through holes 10 corresponding to the ropes. After the components of the disassembled hydraulic support are placed on the bearing plate 5, the components are bound to the support base 1 using ropes, thereby fixing the position of the components. The connection method between the rope and the bearing plate 5 is as follows: after the end of the rope passes through the through hole 10, it is fixed by a limiting rod. Specifically, a collar is formed around the end of the rope, and the collar is fitted onto the limiting rod. The length of the limiting rod is greater than the diameter of the through hole 10, which can restrict the position of the rope end and prevent the rope end from passing through the through hole 10 in the opposite direction, thereby fixing the rope to the bearing plate 5.
[0042] Example 8
[0043] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 5 As shown, to facilitate the installation of the wheel 8 and the axle 20 that mates with the wheel 8, two opposing extension brackets 19 are provided on the base plate 4, and the axle 20 is mounted on the two extension brackets 19. A support plate 14 is provided on the extension brackets 19. To prevent the wheel 8 from falling off the underground conveying track, a retaining ring 16 is fixedly installed on the inner side of the wheel 8. A connecting plate 11 is connected to the bearing plate 5, and a connecting hole 12 is provided on the connecting plate 11 for the winch's connecting rope to pass through. The connecting ring passes through the connecting hole 12 and is then fixed.
[0044] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
