Description

Technical Field

[0001] The present invention relates to the technical field of inspection and maintenance of mining support equipment, in particular to an assembly platform and an assembly method of a hydraulic support. Background Art

[0002] like Fig. 9 In the repair and maintenance work of the hydraulic support shown, the installation of the top beam 1 and the base 4 is the most critical and main process of the hydraulic support assembly. Due to the structural characteristics of the hydraulic support, the disassembly and assembly of the top beam 1 and the base 4 are still completely completed manually with the assistance of lifting equipment. The specific process is: first install the front and rear four columns 2 and the front and rear four connecting rods 5 on the base 4, lift the top beam 1 to the top of it through the gantry crane, manually adjust the columns 2 and the connecting rods 5 to the correct angle position, and then place the top beam 1 on the columns 2 and the connecting rods 5, and then manually complete the installation of the pins on the top of the columns 2 and the upper part of the connecting rods 5. During the process, when the top beam 1 is not installed in place, the columns 2 and the connecting rods 5 are not positioned. At this time, the column 2 is only positioned by the spherical surface at the bottom and the spherical socket of the base 4, and can swing freely in the front, back, left and right directions without positioning; the connecting rod 5 is connected to the hinge support of the base 4 by the pin, and can swing freely around the circumferential direction of the pin. And because the top beam 1 is almost completely covered above the base 4, it is impossible to use a crane to lift the columns 2 or the connecting rods 5, and the four columns 2 and the front and rear four connecting rods 5 can only be manually straightened or adjusted to the correct position corresponding to the top beam 1.

[0003] This results in the following technical problems in the assembly of the top beam 1 and the base 4:

[0004] High labor intensity: the column 2, the connecting rod 5 and the pin are all heavy parts (components), and the manpower consumption during the installation process is large, and more assembly workers are required.

[0005] There are safety hazards: Since the top beam 1 is located directly above the construction workers during installation, there are great safety hazards. If the wire rope for hoisting the top beam 1 fails, the columns 2 and the connecting rods 5 will be in an unstable state, which will seriously threaten the lives of the construction workers working below.

[0006] Low overall efficiency: The assembly time of a single bracket is 1 hour or more. Due to the large loss of manpower during assembly, continuous work cannot be performed, and only 2-3 brackets can be assembled per shift. Summary of the invention

DETAILED DESCRIPTION

[0035] like Figure 1 As shown, an assembly platform of a hydraulic support of the present invention is used as follows Fig. 9 The continuous assembly of the hydraulic support shown mainly includes a transfer system of the hydraulic support and an assembly system of the hydraulic support. The transfer system is used to send the base 4 equipped with the column 2 and the connecting rod 5 into the assembly system, and receive the hydraulic support assembled by the assembly system and send it out. The assembly system is used to adjust the column 2 and the connecting rod 5 on the hydraulic support to the designed angle, and assemble the top beam 1 on the upper end of the column 2 and the connecting rod 5 to complete the assembly of the hydraulic support.

[0036] Combination Figure 1 and Figure 2 As shown, the transfer system includes a second longitudinal track 3 arranged on the ground and a second pallet 9 slidably arranged on the second longitudinal track 3. The second pallet 9 is provided with a first pallet 10 for directly carrying the base 4 equipped with the column 2 and the connecting rod 5. The first pallet 10 is slidably mounted on the third transverse track 34 arranged on the second pallet 9. The first pallet 10 and the second pallet 9 cooperate through a track-slider structure (not shown in the figure) distributed in the transverse direction, so that the first pallet 10 and the base 4 thereon can slide in the transverse direction. A second transverse track 6 is provided on the ground on the right side of the middle of the second longitudinal track 3, and the above-mentioned assembly system is arranged on the right side of the second transverse track 6, so that a waiting station B is formed on the second longitudinal track 3 corresponding to the left end of the second transverse track 6, and a travel preparation station A and a finished product station C are respectively arranged on both sides of the waiting station B on the second longitudinal track 3.

[0037] Preparation station A is used to carry the base 4, and personnel or other equipment connect the columns 2 and the connecting rods 5 to the base 4 respectively. After the assembly of the columns 2 and the connecting rods 5 is completed, the base 4 enters the waiting station B along the second longitudinal track 3 from the second pallet 9. The slider at the bottom of the first pallet 10 in the waiting station B can slide to the right from the track on the top of the second pallet 9 to the second transverse track 6 under the action of external force (conventional technical means in this field, not shown in the figure), so that the base 4 on the first pallet 10 enters the assembly system for assembly. After assembly, the hydraulic support still returns to the left with the first pallet 10 to the second pallet 9 on the waiting station B, and then moves upward with the second pallet 9 to the finished product station C, and is hoisted away by related equipment. The above track system is arranged in a T-shape, which realizes the continuous assembly production of the base 4 and the top beam 1 of the hydraulic support, greatly improving the degree of automation and assembly efficiency of the present invention.

[0038] The assembly system includes a base adjustment device 32 for adjusting the angle of the column 2 and the connecting rod 5 on the base 4 and a top beam adjustment device 33 for assembling the top beam 1 on the upper end of the column 2 and the connecting rod 5 adjusted to the designed angle, which are described below respectively:

[0039] Combination Figure 1 , Figure 3 and Figure 4 As shown, the base adjustment device 32 includes two bases 12 which are respectively distributed laterally, and an assembly station F is formed between the two bases 12. The bottoms of the two bases 12 are provided with flaps 11 which are distributed away from the assembly station F. The bottoms of the flaps 11 are slidably matched with the first longitudinal track 8 which is longitudinally arranged on the ground and located on the outside of the second transverse track 6, so that the two bases 12 are respectively fitted to the two sides of the base 4 located in the assembly station F to complete the angle adjustment of the column 2 and the connecting rod 5, or are respectively away from the assembled hydraulic support in the assembly station F, so that the assembled hydraulic support can return to the left with the first pallet 10 to the second pallet 9 on the waiting station B.

[0040] In order to adjust the angles of the column 2 and the connecting rod 5, a column adjustment mechanism 13 and a connecting rod adjustment mechanism 15 are respectively provided on the two bases 12. The column adjustment mechanism 13 is used to adjust the rotation angle of the column 2 and support the positioning, and the connecting rod adjustment mechanism 15 is used to adjust the rotation angle of the connecting rod 5 and support the positioning.

[0041] The column adjustment mechanism 13 includes a third driving member 1303, a column adjustment arm 1302 and a column clamping member 1301. The third driving member 1303 is a motor reducer assembly having an output shaft that provides rotary motion, and the following driving members are the same. The housing of the third driving member 1303 is fixed on the base 12, and its output end is fixedly connected to the lower end of the column adjustment arm 1302, and its output end coincides with the rotation center of the column 2 at the corresponding position on the base 4. The column clamping member 1301 includes an L-shaped pressing block 1301-1 fixed to the upper end of the column adjustment arm 1302, a locking pressure plate 1301-2 hinged on the L-shaped pressing block 1301-1, and a third push-pull element 1301-3 arranged at the end position of the L-shaped pressing block 1301-1. The third push-pull element 1301-3 in this embodiment is a cylinder, and the following push-pull elements are all cylinders or oil cylinders. The cylinder body of the third push-pull element 1301-3 is hingedly connected to the L-shaped pressure block 1301-1, and the telescopic end is hingedly connected to the middle part of the locking pressure plate 1301-2, so that the locking pressure plate 1301-2 can be driven toward or away from the L-shaped pressure block 1301-1 by the telescopic end of the third push-pull element 1301-3, and the column 2 can be clamped or released.

[0042] The connecting rod adjustment mechanism 15 includes a fifth driving member 1503, a connecting rod adjustment arm 1502 and a connecting rod clamping block 1501. The housing of the fifth driving member 1503 is fixed on the base 12, and its output end is fixedly connected to the lower end of the connecting rod adjustment arm 1502, and its output end coincides with the rotation center of the corresponding connecting rod 5 located on the base 4. The connecting rod clamping block 1501 has a U-shaped cross section, and its inner groove width corresponds to the width of the connecting rod 5, so that the connecting rod 5 is limited in its own rotation direction by the two side walls of the inner groove of the connecting rod clamping block 1501, so as to support and fix the position of the connecting rod 5.

[0043] Based on the above structure, the implementation process of the base adjustment device 32 is as follows:

[0044] After the base 4 equipped with the column 2 and the connecting rod 5 enters the assembly station F, the two bases 12 are moved along the first longitudinal track 8 to the two sides of the base 4, and the connecting rod 5 is correspondingly inserted into the connecting rod block 1501, and the column 2 is correspondingly inserted into the column clamping piece 1301, and the third push-pull element 1301-3 drives the locking plate 1301-2 to move to clamp and fix the column 2. Figure 4 After the third driving member 1303 and the fourth driving member 1401 are respectively started and the column 2 and the connecting rod 5 are respectively rotated to the assembly angle, the top beam adjustment device 33 can assemble the top beam 1 to the upper ends of the column 2 and the connecting rod 5 until Figure 5 Status shown.

[0045] In order to solve the problem of pin hole misalignment caused by the self-rotation of the piston rod of the column 2 during the extension process, the present invention also includes a limit plate 20 imitating the top beam 1 to limit the self-rotation of the piston rod of the column 2 during the lifting process of the column 2. Figure 6 As shown, the limit plate 20 is rectangular, and base blocks 18 are respectively provided at the four corners of the lower edge thereof. The base block 18 is provided with a circular groove 19 adapted to the upper end of the piston rod of the column 2. U-shaped grooves 17 are respectively provided on both sides of the circular groove 19 on the base block 18, and corresponding positioning holes 16 are respectively provided on the groove walls on both sides of the U-shaped groove 17. When the piston rod of the column 2 is not extended, the limit plate 20 is buckled and installed on the upper ends of all four columns 2. Then, the pin is inserted into the upper end of the piston rod of the column 2 through the U-shaped groove 17, and the positioning pin is passed through the positioning hole 16 for positioning. Finally, the oil cylinder of the column 2 is filled with oil to make the four piston rods extend synchronously, and through Figure 4The two column adjustment mechanisms 13 on the right side adjust the corresponding columns 2 to the set position, and the column adjustment arms 1302 in the two column adjustment mechanisms 13 on the left side move accordingly. After the limit plate 20 is smoothly and horizontally raised to the assembly height, the column adjustment arms 1302 in the two column adjustment mechanisms 13 on the right side are fixed, and the column adjustment arms 1302 of the two column adjustment mechanisms 13 on the left side are driven to rotate, so that the two columns 2 on the left side are rotated to the set position. After all four columns 2 are rotated to the set position, the limit plate 20 can be removed and the top beam 1 can be assembled.

[0046] Combination Figure 1 , Figure 7 and Figure 8 As shown, the top beam adjustment mechanism H includes a rectangular frame-type adjustment frame 22, and the two long sides of the bottom of the adjustment frame 22 are slidably matched with the two first transverse rails 7 arranged on the outside of the second transverse rail 6 in the transverse direction. Lifting plates 25 are respectively arranged at the positions of the two ends of the adjustment frame 22, and the lifting plates 25 are rectangular and distributed along the width direction of the adjustment frame 22. First driving members 23 are respectively arranged at the two ends of the lifting plates 25, and the output shaft of the first driving member 23 is provided with a gear 27, and the gear 27 is meshed with the rack 26 arranged along the high side of the adjustment frame 22, so that the two lifting plates 25 are synchronously lifted and lowered in the process of the four first driving members 23 synchronously driving the gear 27 to rotate. In order to prevent the lifting plates 25 from moving in the transverse direction, in this embodiment, a vertically distributed sliding column is provided in the adjustment frame, and the sliding column is slidably matched with the linear bearing arranged on the lifting plates 25 and distributed in the vertical direction, so as to ensure that the gear 27 and the corresponding rack 26 are always in a meshing state. The above structures in which the sliding column and the linear bearing cooperate to realize the lifting and lowering of the lifting plate 25 only in the vertical direction are not conventional technical means in the art. In order to avoid being blocked in the drawings, they are not shown in the drawings of the present invention.

[0047] A second driving member 24 is provided in the middle of the lifting plate 25. The output shafts of the two second driving members 24 are concentric and arranged opposite to each other. A flip plate 21 is connected to the output shafts of the two second driving members 24. Thus, the flip plate 21 is rotated synchronously and in the same amplitude by the two second driving members 24. The flip plate 21 is a rectangular plate, and a flip station G is formed on its plate surface. A positioning mechanism for fixing the top beam 1 is provided on the flip station G. Figure 7 As shown, the positioning mechanism includes two side plates 28 fixed at intervals on the flip plate 21, and the side plates 28 are provided with positioning pin holes 29, and positioning pins connected to the process holes at the base position of the base 4 are inserted into the positioning pin holes 29. Two strip holes 31 are provided at intervals on the flip plate 21, and a first push-pull element 30 is penetrated through the strip hole 31. The cylinder body of the first push-pull element 30 is hingedly connected to the flip plate 21, and an adjustment pin is provided at the telescopic end, and the adjustment pin is used to connect with the process hole at the rotating body position of the base 4.

[0048] Based on the above structure, during the assembly process, first, when the adjustment frame 22 is moved to the right out of the base adjustment device 32, and the lifting plate 25 and the flip plate 21 are both in the low position, the top beam 1 is fixed to the flip station G through the positioning mechanism, and the top beam 1 is connected to the telescopic end of the first push-pull element 30. Then, the lifting plate 25 drives the flip plate 21 to rise to the high position, and the flip plate 21 rotates 180°, so that the various assembly positions at the bottom of the top beam 1 are distributed downward, and the right side of the top beam 1 is controlled to rotate to the designed state through the first push-pull element 30. Finally, the adjustment frame 22 is moved to the left to the assembly station F, and then the lifting plate 25 is lowered to make the various assembly positions at the bottom of the top beam 1 dock with the upper ends of the columns 2 and the connecting rods 5 respectively, and the corresponding pins can be inserted to complete the assembly of the top beam 1 and the base 4 of the hydraulic support.

[0049] Finally, in order to facilitate the assembly of the pin shaft at the top of the connecting rod 5, the present invention further provides a pin-installing mechanism 14 on the base 12 of the base adjustment device 32. The pin-installing mechanism 14 is used to assemble the pin shaft for hinged connection between the upper end of the connecting rod 5 and the top beam 1 into place after the top beam 1 of the hydraulic support is assembled to the column 2 and the upper end of the connecting rod 5. Figure 3 and Figure 4 As shown, the pinning mechanism 14 includes a fourth driving member 1401 fixed on the base 12, a rocker arm 1404 whose lower end is fixed on the fourth driving member 1401, and a second push-pull element 1403 fixed at the upper end of the rocker arm 1404. The cylinder of the second push-pull element 1403 is fixed to the rocker arm 1404, and the telescopic end penetrates the thickness distribution of the rocker arm 1404. A bracket 1402 is provided on the other side of the second push-pull element 1403 on the rocker arm 1404, and the bracket 1402 is concentrically corresponding to the telescopic end of the second push-pull element 1403, and is used to place the pin to be installed. After the top beam 1 of the hydraulic support is equipped with the column 2 and the upper end of the connecting rod 5, and the pin at the upper end of the connecting rod 5 is placed in the bracket 1402, the fourth driving member 1401 drives the rocker arm 1404 to rotate to the corresponding pin hole, and the telescopic end of the second push-pull element 1403 extends to penetrate the pin into the corresponding pin hole.
