[0001] The present invention belongs to the technical field of large mining height tunnel support, and specifically relates to a variable arrangement large working resistance super-high advance hydraulic support. Background Art

[0002] my country is rich in coal resources, and the mining of thick and extra-thick coal seams plays an important role in ensuring coal production and supply capabilities. In recent years, with the continuous development of mechatronics, comprehensive mining mechanization and automated control, my country's mining industry has been pushed into a fast track. Among them, the development of large-height comprehensive mining technology has played an important role in the mining of thick and extra-thick coal seams.

[0003] In the existing technology, due to the continuous development of large-height comprehensive mining technology, the equipment in the mining area is getting larger and larger, which puts higher requirements on the tunnel support equipment on both sides of the mining area. If the support equipment on both sides of the tunnel is not upgraded, the tunnel surrounding rock environment is complicated, and it is difficult to achieve effective protection of personnel and equipment. It is also inconvenient for operators to transport it conveniently, which may affect the efficiency of normal coal mining work. It is also troublesome for operators to disassemble the equipment, which increases the workload of operators and reduces practicality.

[0004] Therefore, we propose a variable arrangement large working resistance super-high advance hydraulic support to solve the surrounding rock environment of tunnels in different situations. It can achieve the purpose of effective protection of personnel and equipment, and also facilitate transportation and installation. Summary of the invention

[0005] The purpose of the present invention is to solve the problems mentioned in the above background technology, and to propose a variable arrangement large working resistance super high advance hydraulic support.

[0006] The object of the present invention can be achieved by the following technical scheme: A variable arrangement large working resistance super-high advance hydraulic support, comprising a front frame, a middle frame is arranged at the top position in front of the front frame through a connector, and the number of the middle frames is three, and a rear frame is arranged at the bottom position in front of the middle frame through a connecting assembly;

[0007] The rear frame includes two bottom plates, and the front of the upper surfaces of the two bottom plates are fixedly connected with support frames, and the number of the support frames is four, and the bottom position in front of the two bottom plates is fixedly connected with a fixed plate, and a pin shaft 1 is arranged inside the four support frames, and a connecting rod is arranged on the outer surface of the pin shaft 1.

[0008] As a preferred embodiment of the present invention, a movable frame is provided at the top of the connecting rod through a second pin, a fixed frame is provided above the inner wall of the movable frame through a third pin, and the number of the fixed frames is four.

[0009] As a preferred embodiment of the present invention, load-bearing plates are fixedly connected to the upper surfaces of the four fixing frames, and the number of the load-bearing plates is two.

[0010] As a preferred embodiment of the present invention, lifting jacks are provided on the lower surfaces of the two load-bearing plates, and the number of the lifting jacks is four.

[0011] As a preferred embodiment of the present invention, the connecting assembly includes a push beam, a square fixing groove is fixedly connected to the middle position of the upper surface of the push beam, and the number of the square fixing grooves is two, and a threaded limiting groove is opened at the front position of the upper surface of the push beam.

[0012] As a preferred embodiment of the present invention, a limiting frame 1 is arranged in the middle position in front of the push beam, a square groove is opened on the inner wall of the limiting frame 1, and a reinforcing clip is arranged on the inner wall of the square groove, and the number of the reinforcing clips is two, and a threaded fixing rod is threadedly connected to the side of the two reinforcing clips away from the limiting frame 1, and two limiting frames 2 are arranged on the left and right sides in front of the push beam.

[0013] As a preferred embodiment of the present invention, a card block is arranged inside the limit frame 1, a square block is inserted at the bottom position of the inner wall of the card block, two circular plates are fixedly connected to the front of the two limit frames 2, and a push jack is fixedly connected to the middle position in front of the two circular plates.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) This group of supports is usually arranged and combined in a single-in-front-double-in-back manner using a push beam, a connecting assembly, a connecting head and a push jack, and the support is moved forward and backward by the hydraulic pressure of the push jack. When the stress in the tunnel changes, the double-row supports in the last row can be changed to a single-row support according to the support required by the tunnel, and placed in the last row of the group of supports, thereby turning five groups of supports into six groups of supports. The push beam can connect two supports to increase the support width and improve the working resistance. It can also be connected to a support to narrow the width of the support for easy transportation, so that it can be applied to tunnel surrounding rock environments in different situations to achieve the purpose of effective protection of personnel and equipment.

DETAILED DESCRIPTION

[0024] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Embodiment 1:

[0026] See also Figure 1 - Figure 3 As shown, a variable arrangement large working resistance ultra-high advance hydraulic support comprises a front frame 1, a middle frame 2 is arranged at the top position in front of the front frame 1 through a connector 28, and the number of the middle frames 2 is three, and a rear frame 4 is arranged at the bottom position in front of the front middle frame 2 through a connecting assembly 3;

[0027] The rear frame 4 includes two bottom plates 5, and the front of the upper surfaces of the two bottom plates 5 are fixedly connected with support frames 6, and the number of the support frames 6 is four. The bottom position in front of the two bottom plates 5 is fixedly connected with a fixing plate 7, and a pin shaft 8 is arranged inside the four support frames 6, and a connecting rod 9 is arranged on the outer surface of the pin shaft 8.

[0028] In the existing technology, due to the continuous development of large-height comprehensive mining technology, the equipment in the mining area is getting larger and larger, which puts higher requirements on the tunnel support equipment on both sides of the mining area. If the support equipment on both sides of the tunnel is not upgraded, the tunnel surrounding rock environment will be complicated, making it difficult to effectively protect personnel and equipment, and it will be inconvenient for operators to transport them conveniently, which may affect the efficiency of normal coal mining work.

[0029] When the operator uses the device to work, he first connects the front frame 1 to the rear of the middle frame 2 through the connector 28, and then connects the rear frame 4 to the front of the middle frame 2 through the connector assembly 3. Then, the lifting action of the lifting jack 15 will cause the load-bearing plate 14 to move up and down, thereby providing support. This group of brackets is usually arranged and combined in a single-front and double-back manner using a push beam 16, a connector assembly 3, a connector 28 and a push jack 27, and the brackets are moved forward and backward by the hydraulic pressure of the push jack 27. When the stress of the roadway changes, the double-row brackets in the last row can be changed into a single-row bracket according to the required support of the roadway, and placed in the last row of the bracket group, so that five groups of brackets can be changed into six groups of brackets. The push beam 16 can connect two brackets to increase the support width and improve the work resistance. It can also connect one bracket to narrow the bracket width for easy transportation, so that it can be applied to the surrounding rock environment of the roadway in different situations, achieving the purpose of effective protection of personnel and equipment, and can also be arranged and combined to facilitate transportation and installation.

[0030] Embodiment 2:

[0031] Please refer to Figure 4 - Figure 5As shown, a movable frame 11 is provided at the top of the connecting rod 9 through a pin shaft 2 10, a fixing frame 13 is provided above the inner wall of the movable frame 11 through a pin shaft 3 12, and the number of the fixing frames 13 is four, and the upper surfaces of the four fixing frames 13 are fixedly connected with a load-bearing plate 14, and the number of the load-bearing plates 14 is two, and the lower surfaces of the two load-bearing plates 14 are provided with lifting jacks 15, and the number of the lifting jacks 15 is four, and the connecting assembly 3 includes a push beam 16, and a square fixing groove 17 is fixedly connected to the middle position of the upper surface of the push beam 16, and the number of the square fixing grooves 17 is two, and a threaded limit groove 18 is provided at the front position of the upper surface of the push beam 16 A limit frame 19 is provided in the middle position in front of the push beam 16, and a square groove 20 is provided on the inner wall of the limit frame 19. A reinforcing clip 21 is provided on the inner wall of the square groove 20, and the number of the reinforcing clips 21 is two. The two reinforcing clips 21 are threadedly connected with a threaded fixing rod 22 on one side away from the limit frame 19. Two limit frames 23 are provided on the left and right sides in front of the push beam 16. A card block 24 is provided inside the limit frame 19, and a square block 25 is inserted at the bottom position of the inner wall of the card block 24. Two circular plates 26 are fixedly connected to the front of the two limit frames 23, and a push jack 27 is fixedly connected to the middle position in front of the two circular plates 26;

[0032] In the prior art, it is also troublesome for operators to disassemble the device, and a large amount of manpower is required to disassemble the rear frame 4, and then reinstall the rear frame 4, changing the five sets of brackets into six sets of brackets, thereby increasing the workload of operators and reducing practicality;

[0033] When the operator uses the connecting assembly 3 to disassemble the rear frame 4, the left rear frame 4 is moved by the hydraulic pressure of the pushing jack 27. After the pushing jack 27 is moved, the operator removes the square block 25 from the lower surface of the block 24, and then rotates the threaded fixing rods 22 on both sides of the pushing beam 16, removes the threaded fixing rods 22 from both sides of the pushing beam 16, and then removes the block 24 on the upper surface of the reinforcing clip 21, and moves the right rear frame 4 to the middle position of the pushing beam 16. The operator then inserts the block 24 through the limiting frame 23, the reinforcing clip 21 and the pushing beam 16, and then uses the square block 25 for limiting. After fixing the right rear frame 4 in front of the middle frame 2, the operator moves the left rear frame 4 to the back of the right rear frame 4 for fixing, thereby avoiding the operator consuming a lot of manpower to disassemble and shift the rear frame 4, reducing the operator's workload, while also improving the operator's work efficiency, simplifying the entire disassembly steps, and improving practicality.

[0034] The specific working process of the present invention is as follows:

[0035] When the operator uses the device to work, he first connects the front frame 1 to the rear of the middle frame 2 through the connector 28, and then connects the rear frame 4 to the front of the middle frame 2 through the connector assembly 3. Then, the lifting action of the lifting jack 15 will cause the load-bearing plate 14 to move up and down, thereby providing support. This group of brackets is usually arranged and combined in a single-in-front and double-in-back manner using a push beam 16, a connector assembly 3, a connector 28, and a push jack 27, and the brackets are moved forward and backward by the hydraulic pressure of the push jack 27. When the stress of the lane changes, the double-row brackets in the last row can be changed to single-row brackets according to the support required by the lane, and placed in the last row of the bracket group, so that five groups of brackets can be changed to six groups of brackets, and the push beam 16 can connect two brackets;

[0036] When the operator uses the connecting assembly 3 to disassemble the rear frame 4, the left rear frame 4 is moved by the hydraulic pressure of the push jack 27. After the push jack 27 is used to move the frame, the operator removes the square block 25 from the lower surface of the block 24, and then rotates the threaded fixing rods 22 on both sides of the push beam 16, removes the threaded fixing rods 22 from both sides of the push beam 16, and then removes the block 24 on the upper surface of the reinforcement clip 21, and moves the right rear frame 4 to the middle position of the push beam 16. The operator then inserts the block 24 through the limiting frame 23, the reinforcement clip 21 and the push beam 16, and then uses the square block 25 for limiting. After fixing the right rear frame 4 in front of the middle frame 2, the operator moves the left rear frame 4 to the back of the right rear frame 4 for fixing.
