[0032] In order to better explain the utility model, so as to facilitate understanding, the following will be combined with the specific embodiments, the utility model is described in detail.

[0033] Example 1:

[0034] Referring to Figures 1 to 4 , the embodiment provides a dismounting platform for fully mechanized hydraulic support, for dismounting roof beam in fully mechanized hydraulic support. Specifically, the dismounting platform for fully mechanized hydraulic support of the embodiment comprises platform body 1 and dismounting device 2, multiple clamping devices 3 and two hoisting fixing devices 4 fixed on platform body 1, as described below.

[0035] The clamping device 3 in the embodiment can fix the roof beam below the platform body 1. Two hoisting fixing devices 4 are transversely and side by side on the platform body 1, each hoisting fixing device 4 comprises a first jack 41 and two fixing pins 42 at both ends of the hoisting fixing device 4, the fixing pin 42 is matched with the hoisting hole on the roof beam, and the two fixing pins 42 in the same hoisting fixing device 4 are inserted into and pulled out of the hoisting hole through the first jack 41. The dismounting device 2 is fixed at one end of the platform body 1, and the dismounting device 2 comprises two second jacks 21 and two connecting bolts 23 driven and connected one by one, the two connecting bolts 23 can be detachably connected with two to-be-dismounted pin shafts 5 one by one, and the pulling out and insertion of the to-be-dismounted pin shaft 5 are realized through the second jack 21.

[0036] Specifically, the embodiment is for dismounting a top beam in a fully mechanized hydraulic support. One end of the top beam is connected with a shield beam through two pin shafts 5. Therefore, dismounting the top beam is to dismount the two pin shafts 5 connecting the top beam with the shield beam. The two pin shafts 5 are inserted from both sides of the connecting end of the top beam and the shield beam. One end of each pin shaft 5 close to the side edge of the top beam has a threaded hole 51. The top beam has two equal long edges and two equal short edges. The top beam is axisymmetric about the connecting line of the midpoints of the short edges. The top beam further has four hoisting holes arranged axisymmetrically on both sides. The distance between the two hoisting holes on one side is equal. The dismounting device 2, the clamping device 3 and the hoisting fixing device 4 are fixedly connected with the platform body 1 by welding, screwing or clamping. The multiple clamping devices 3 are arranged on both sides of the platform body 1 and can clamp the top beam to fix the top beam below the platform body 1. The two hoisting fixing devices 4 are distributed transversely above the platform body 1. The distance between the two hoisting fixing devices 4 is equal to the distance between the two hoisting holes on one side of the top beam. The first jack 41 on each hoisting fixing device 4 can drive the fixed pin 42 to displace to increase or decrease the distance between the two fixed pins 42. Therefore, when each fixed pin 42 is aligned with the hoisting hole, the first jack 41 drives the fixed pin 42 to contract inward to insert the fixed pin 42 into the hoisting hole, thereby fixing the hoisting fixing device 4 with the hoisting hole. The dismounting device 2 is fixed to one end of the platform body 1 opposite to the pin shaft 5 to be dismounted. The two second jacks 21 are center-symmetric about the center of the dismounting device 2. The two connecting bolts 23 can simultaneously align with and insert into the threaded holes 51 on the pin shaft 5 to be dismounted. Therefore, driving the two second jacks 21 can realize the dismounting of the pin shaft 5.

[0037] In summary, compared with the prior art, the damage of the pin shaft 5 caused by traditional gas cutting dismounting is avoided, the pin shaft 5 is reused, and the cost of parts and consumables is reduced. Mechanized operation replaces manual high-intensity operation, reduces the dependence on skilled workers, and improves the dismounting efficiency. The multi-dimensional fixing structure ensures the stability and reliability of the top beam during operation, eliminates the safety hazards caused by gas cutting, and integrates the functions of dismounting and mounting to meet the dismounting and mounting requirements. The modular design forms the systematic advantages of positioning, fixing and power transmission, and solves the problems of high cost, low efficiency and poor safety in the prior art. It has high industrial application value of high efficiency, safety and low cost.

[0038] Further, each hoisting fixing device 4 includes two symmetrically arranged support arms 43. The hoisting space accommodating the top beam is formed between the support arms 43. The fixed pin 42 is arranged on the inner side of the support arm 43. The hoisting fixing device 4 includes two support arms 43 which are axisymmetric about the vertical line passing through the midpoint. The hoisting space through which the fixed pin 42 is inserted into the hoisting hole to fix the top beam below the platform body 1 is formed between the two support arms 43.

[0039] Furthermore, the disassembly and assembly device 2 also includes a connecting block 22. One end of the connecting block 22 is fixedly connected to the lifting end of the second jack 21, and the other end of the connecting block 22 is detachably connected to a connecting bolt 23. The connecting bolt 23 extends from the connecting block 22 toward the top beam. The connecting bolt 23 can be detachably connected to the threaded hole 51 at the outer end of the pin 5 to be disassembled near the top beam, and the axial displacement of the second jack 21 drives the pin 5 to be disassembled to move. Since the two second jacks 21 are arranged side by side, one second jack 21 is located directly above the pin 5 to be disassembled, and the other second jack 21 is located diagonally above the pin 5 to be disassembled. Therefore, the connecting block 22 of the other second jack 21 extends from the lifting end of the other second jack 21 to the connecting bolt 23 connected to the connecting block 22. One end of the connecting block 22 is fixedly connected to the second jack 21 by welding, screwing or riveting. The other end of the connecting block 22 has a smooth hole. The connecting bolt 23 is inserted into the disassembly and assembly device 2 from the other end of the connecting block 22. Therefore, through the threaded connection between the connecting bolt 23 and the threaded hole 51, the second jack 21 can drive the pin to be disassembled and assembled to move axially, so as to realize the disassembly and assembly of the pin to be disassembled and assembled.

[0040] Furthermore, a distance measuring instrument is provided on the connecting block 22 to measure the distance from the connecting block 22 to the side of the top beam. The distance between the connecting block 22 and the side of the top beam can be calculated when the pin 5 to be disassembled is pulled out or fully installed. The distance measuring instrument can measure the distance between the connecting block 22 and the side of the top beam in real time. When the distance measuring instrument reaches the pre-calculated distance, the disassembly and assembly of the pin 5 to be disassembled is considered complete.

[0041] Furthermore, the thread length of the connecting bolt 23 is greater than the depth of the threaded hole 51 in the pin 5 to be disassembled. In order to enhance the connection strength between the connecting bolt 23 and the threaded hole 51, the thread length of the connecting bolt 23 is greater than the depth of the threaded hole 51 in the pin 5 to be disassembled, and when the connecting bolt 23 is screwed into the bottom of the threaded hole 51, the remaining length of the connecting bolt 23 is fixed, which facilitates the calculation of the distance between the connecting block 22 and the side of the top beam.

[0042] Furthermore, the width of the platform body 1 is equal to the width of the top beam. The top beam is mass-produced and has uniform specifications; therefore, the size of the top beam is fixed. When the width of the platform body 1 and the top beam are the same, it is convenient for the clamping device 3 and the hoisting and fixing device 4 to fix the top beam.

[0043] Furthermore, multiple clamping devices 3 are distributed on both sides of the platform body 1, and anti-slip pads are provided on the inner side of the clamping devices 3. In order to achieve better anti-slip effect, the clamping devices 3 are distributed on both sides of the platform body 1, and the friction between the clamping devices 3 and the top beam can be increased by setting the anti-slip pads on the inner side.

[0044] Further, the fixed pin 42 is sleeved with a rubber ring at one end close to the support arm 43 to prevent the fixed pin 42 from damaging the lifting hole. In order to protect the top beam from being damaged after being disassembled, the rubber ring is arranged at one end of the fixed pin 42 close to the support arm 43, and the fixed pin 42 abuts against the lifting hole through the rubber ring when the fixed pin 42 is completely inserted into the lifting hole.

[0045] Embodiment 2:

[0046] With reference to Figure 5 The embodiment provides that the bridge crane and the disassembling platform work together to transfer the top beam after the disassembly and assembly of the pin shaft 5 are completed, and details are as follows.

[0047] In the embodiment, the platform body 1 is provided with a plurality of lifting positions connected with the bridge crane and used for adjusting the angle of the disassembling platform and driving the disassembling platform to move. The plurality of lifting positions are distributed in an equilateral triangle on the platform body 1. The lifting positions are connected with hooks on the bridge crane, and the equilateral triangle distribution is beneficial to maintaining the stability of the top beam in the lifting process. In addition, the top beam has a certain angle on the fully-mechanized hydraulic support, and in order to make the disassembling platform and the top beam fit better when the disassembling platform is fixed to the top beam, the up-down position of the hook is adjusted to make the angle of the disassembling platform consistent with that of the top beam. When the pin shaft 5 is disassembled, the bridge crane can lift the top beam to prevent the top beam from falling and hurting people, and the top beam can be moved to a suitable place for stacking and inspection. When the pin shaft 5 is assembled, fewer people can complete the assembly of the pin shaft 5, thereby saving labor and speeding up the assembly.
