Description

TECHNICAL FIELD

[0001] The utility model relates to the field of underground support moving, especially to a supporting support step -by -step pull -move equipment. BACKGROUND

[0002] Supporting support equipment needs to advance with tunneling in the tunneling process, due to the huge and heavy weight of the support equipment, pure reliance on manpower cannot advance the support equipment. The processing mode for the related problems in the prior art is to control the single hydraulic prop by the worker, make the piston part of the single hydraulic prop press against the support and drive the support to move. However, the single hydraulic prop exerts force with the roadway side as the fulcrum when performing the action, which leads to the inevitable inclination of the moving stroke of the support, so it is necessary to repeatedly push the support on both sides of the roadway in this case, and finally the support equipment is stably placed in the roadway. The operation process is very complicated, the physical loss is also large, especially the construction steps still need a large amount of manual participation, which is not conducive to construction safety.

[0004] The equipment comprises a walking unit and a support connecting unit.

[0005] The walking unit comprises a first pressing member, and the first pressing member is fixedly provided with a pull -move member.

[0006] The piston part of the pull -move member is fixedly connected with a second pressing member, the rear part of the second pressing member is provided with a support connecting unit, the support connecting unit comprises a support connecting body, the support connecting body is fixedly connected with the second pressing member, and the support connecting body is further provided with a support interlocking member.

[0007] The effect realized by the support interlocking member and the underground temporary support is locked connection, wherein the support connecting body synchronously plays a supporting role; that is, the support connecting body can be regarded as the front end of the temporary support.

[0008] The first pressing member acts, the top surface of the first pressing member abuts against the top surface of the roadway to form stable support, the pull -move member acts to drive the whole equipment to move forward, that is, to drive the temporary support to move forward.

[0009] The first pressing member acts, the piston moves downward to make the first pressing member separate from the roof of the roadway, the second pressing member moves upward to make the top surface of the second pressing member abut against the top surface of the roadway, and the pull -move member acts to push the first pressing member to move forward.

[0010] By repeating the above steps, the equipment can be made to move in a stepping manner, which means moving the temporary support frame.

[0011] The beneficial effects of this utility model are: it solves the problem of inconvenient relocation of temporary support supports in the prior art, and realizes the smooth and safe movement of temporary support supports. In particular, no human intervention is required during equipment implementation, and the walking path is smooth, eliminating the need for repeated adjustments. This greatly improves the safety of implementation. Attached Figure Description

[0020] The piston portion of the pulling member 4 is fixedly connected to the second pressing member 5. A bracket connecting unit is provided at the rear of the second pressing member 5. The bracket connecting unit includes a bracket connecting body 6. The bracket connecting body 6 is fixedly connected to the second pressing member 5. A bracket interlocking member 7 is also provided on the bracket connecting body 6.

[0021] The effect achieved is that the support interlocking component 7 is locked to the downhole temporary support, wherein the support connecting body 6 simultaneously plays a supporting role; that is, the support connecting body 6 can be regarded as the front end of the temporary support.

[0022] The first top pressing member 1 acts, and the top surface of the first top pressing member 1 abuts against the roof of the roadway, forming a stable support. The pulling and moving member 4 acts, driving the whole device to move forward, that is, driving the temporary support bracket to move forward.

[0023] The first top pressing member 1 acts, and the piston moves downward to make the first top pressing member 1 separate from the roof of the roadway. The second top pressing member 5 moves upward, and the top surface of the second top pressing member 5 abuts against the roof of the roadway. The pulling and moving member 4 acts, driving the first top pressing member 1 to move forward.
