Description

Technical Field

[0001] This utility model relates to the field of coal mine support equipment, specifically to an anchoring bracket and a transfer machine with an anchoring bracket. Background Technology

[0002] In some mines, due to conditions such as fractured roofs, soft floors, and abundant loose coal in the roadways, it is difficult to move the transfer conveyor forward. Therefore, external force is needed to drag the transfer conveyor forward. Current technologies mostly employ auxiliary push-pull jacks added to the side, single auxiliary push-pull jacks, or other auxiliary equipment such as winches for dragging. However, these auxiliary devices have drawbacks such as the transfer conveyor easily interfering with the advanced support frame during forward movement, causing jamming, affecting the normal advance of the coal face, and posing safety hazards.

[0003] To avoid interference, patent application CN103527233A discloses an integrated support and transfer device for a fully mechanized mining face transport roadway. Specifically, it includes four sets of columns arranged on the left and right sides. A first connecting rod is installed between the upper ends of the two outer columns, and a second connecting rod is installed between the upper ends of the two inner columns. Pushing jacks are installed on the outer sides of both outer columns. The cylinders of the pushing jacks are connected to the first connecting rods, and the piston rods of the pushing jacks are connected to the second connecting rods. Sliding pins are installed on both the first and second connecting rods directly above the columns, and top beams are fitted onto the sliding pins. Side-tilting plates are hinged to the left and right ends of the two inner top beams, and side-tilting jacks are installed between the side-tilting plates and the top beams. A transfer machine is installed between the two inner columns, and the bases of the two inner columns are set within the slides on the transfer machine's chute, and the two inner columns are connected to the transfer machine. This integrated support and transfer device for the fully mechanized mining face haulage roadway achieves integrated support and transfer, eliminating the jamming phenomenon caused by interference between the transfer machine and the advanced support frame when the transfer machine moves forward. However, the disclosed structure of this integrated support and transfer device for the fully mechanized mining face haulage roadway does not have the function of self-moving transfer machine, and the degree of freedom of the top of the column cannot fully adapt to the needs of the roadway terrain undulations. Utility Model Content

[0004] In order to enable the anchor bracket to move the transfer machine base forward and adapt to the undulating terrain of the tunnel, the technical solution adopted by this utility model is: an anchor bracket, which is connected to the transfer machine base in a transverse manner, including a pushing mechanism, a telescopic support mechanism, a top beam and a pair of bracket bases. The pushing mechanism is connected between a pair of the support bases and is used to push the transfer machine base; Each of the bracket bases is movably connected to a telescopic support mechanism for supporting the top beam. The top beam is rotatably connected to the top of a pair of telescopic support mechanisms via a reset rotation mechanism. The reset rotation mechanism is used to deflect the top beam when subjected to external force and to automatically reset and return the top beam to its original position when not subjected to external force.

[0005] Based on the above, in order to facilitate the movement of the transfer machine base, the moving mechanism includes a jack fixing seat, a moving jack, and a push plate; The jack fixing seat is connected between a pair of the bracket bases; The push jack is installed upside down on the jack base, the push plate is slidably connected to the jack base, and the push plate is connected to the telescopic end of the push jack. The pusher jack is used to extend itself to move the push plate forward, thereby pushing the transfer machine base forward.

[0006] That is, by reversing the installation of the push jack, the thrust is greater than that used in the existing auxiliary moving transfer machine when pulling, making it easier to move the transfer machine.

[0007] Based on the above, in order to facilitate connection, a connecting pin is provided on the front end of the push plate for connecting the transfer machine base. The transfer machine base is connected to the front end of the push plate through the connecting pin in a forward-low-back-high posture, so as to move forward by the thrust of the push jack.

[0008] That is, this structure allows the transfer machine base to pass through the middle of the anchor support, and ear plates are set at the bottom of the transfer machine base to connect the anchor support. The anchor support structure on both sides can be made narrower, occupying less space, and can better adapt to the changes in the cross-sectional width of the underground roadway.

[0009] Based on the above, in order to facilitate guidance during extension and retraction, the telescopic support mechanism includes a guide column and a pair of telescopic columns. The guide column is located between the pair of telescopic columns and is used to guide the pair of telescopic columns during extension and retraction. Based on the above, in order to better adapt to the roadway terrain, the reset rotation mechanism includes a rotation component and a self-resetting component. The rotation component includes a T-shaped rotary joint, a first pin, and a second pin. The first pin and the second pin are arranged vertically. The T-shaped rotary joint is movably connected to the top beam through the first pin, and the T-shaped rotary joint is movably connected to the top of the guide column through the second pin. The self-resetting assembly includes a column ball head, a spring, a limiting block, and a reset rubber. The lower part of the column ball head is installed on the top of the telescopic column. The spring is disposed between the side of the column ball head and the side of the top beam. The reset rubber is sleeved on the column ball head and fixed in the cavity of the top beam. The top of the reset rubber is connected to the limiting block for limiting the column ball head.

[0010] That is, because the top beam is reset by both springs and reset rubber, the top beam has a good reset effect after detaching from the roof of the underground roadway, and can automatically straighten itself when no external force is applied. At the same time, the top beam and the guide column are connected by a rotating assembly, which creates two degrees of freedom of swing, which can satisfy the swing of the top beam in both forward and backward and left and right.

[0011] Based on the above, a slag discharge port is provided on the side of the support base to facilitate the discharge of coal slag inside the anchor support. When it is not necessary to discharge the coal slag accumulated inside the support base, a baffle is used to block the slag discharge port to prevent external debris from entering.

[0012] Based on the above, in order to improve the friction of the top beam, several anti-slip strips are provided on the top of the top beam.

[0013] Based on the above, the guide column is arranged parallel to the pair of telescopic columns.

[0014] This utility model also provides a transfer machine with an anchor bracket, including a transfer machine base and the aforementioned anchor bracket. The transfer machine base is disposed on the anchor bracket, and the anchor bracket is used to move the transfer machine base by means of thrust.

[0015] This utility model has substantial features and progress compared to the prior art. Specifically, the present utility model provides an anchoring bracket and a transfer machine with the anchoring bracket. By connecting the anchoring bracket to the transfer machine base in a transverse manner, the transfer machine base passes through the middle of the anchoring bracket. A reset rotation mechanism is set on the anchoring bracket, so that the anchoring bracket has a high degree of freedom, thereby adapting to the undulations of the tunnel terrain when the transfer machine base is moved forward by using the anchoring bracket.

[0016] Furthermore, the push jacks are installed in reverse. Compared with the existing transfer machines that use pulling force to assist in moving, the push jacks use thrust, which is greater and makes it easier to move the transfer machine. Attached Figure Description

[0023] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0024] Example 1 This embodiment provides an anchoring bracket, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it is connected across the transfer machine base 19 and includes a pushing mechanism, a telescopic support mechanism, a top beam 10 and a pair of support bases 3.

[0025] The pushing mechanism is connected between a pair of support bases 3 and is used to push the transfer machine base 19. Each support base 3 is movably connected to a telescopic support mechanism for supporting the top beam 10.

[0026] The top beam 10 is rotatably connected to the top of the pair of telescopic support mechanisms via a reset rotation mechanism. The reset rotation mechanism is used to deflect the top beam 10 when subjected to external force, and to cause the top beam 10 to automatically reset and return to its original position when not subjected to external force.

[0027] Specifically, to facilitate the movement of the transfer machine base 19, the moving mechanism includes a jack fixing seat 1, a moving jack 2, and a push plate 5. The jack fixing seat 1 is connected between a pair of support bases 3.

[0028] The push jack 2 is mounted upside down on the jack base 1. The push plate 5 is slidably connected to the jack base 1. The push plate 5 is connected to the telescopic end of the push jack 2. The push jack 2 is used to move the push plate 5 forward by extending itself, thereby pushing the transfer machine base 19 forward.

[0029] To facilitate guidance during extension and retraction, the telescopic support mechanism includes a guide post 9 and a pair of telescopic uprights 7. The guide post 9 is located between the pair of telescopic uprights 7 and is used to guide the extension and retraction of the pair of telescopic uprights 7. Specifically, the guide post 9 is arranged parallel to the pair of telescopic uprights 7.

[0030] Example 2 This embodiment provides an anchoring bracket, the main difference from Embodiment 1 being that in this embodiment: Figure 3 and Figure 4 As shown, in order to better adapt to the terrain of the tunnel, the reset rotation mechanism includes a rotation component 11 and a self-resetting component 8.

[0031] The rotating assembly 11 includes a T-shaped rotary joint 18, a first pin 13, and a second pin 12. The first pin 13 and the second pin 12 are arranged vertically. The T-shaped rotary joint 18 is movably connected to the top beam 10 via the first pin 13, and the T-shaped rotary joint 18 is movably connected to the top of the guide column 9 via the second pin 12.

[0032] The self-resetting assembly includes a column ball head 15, a spring 17, a limiting block 14, and a reset rubber 16.

The top of the reset rubber 16 is connected to the limiting block 14 for limiting the column ball head 15.

[0033] That is, because the top beam 10 is reset by both spring 17 and reset rubber 16, the top beam 10 has a good reset effect after being separated from the roof of the underground roadway, and the top beam 10 can automatically straighten when it is not subjected to external force. At the same time, the top beam 10 is connected to the guide column 9 through the rotating assembly 11, which forms two degrees of freedom of swing, which can satisfy the swing of the top beam 10 in the front and back and left and right.

[0034] Example 3 This embodiment provides an anchoring bracket, the main difference from Embodiment 1 being that in this embodiment: Figure 2As shown, a slag discharge port 4 is provided on the side of the support base 3 to facilitate the discharge of coal slag inside the anchor support. When it is not necessary to discharge the coal slag accumulated inside the support base, the slag discharge port 4 is blocked by a baffle to prevent external debris from entering.

[0035] Example 4 This embodiment provides an anchoring bracket. The main difference from Embodiment 1 is that, in order to improve the friction of the top beam, the top of the top beam 10 is provided with several anti-slip strips.
