[0025] The present application will be described in detail below with reference to the drawings and in conjunction with embodiments. Each example is provided by way of explanation of the present application rather than a limitation of the present application. In fact, those skilled in the art will clearly understand that modifications and variations can be made to the present application without departing from the scope or spirit of the present application. For example, features shown or described as part of one embodiment can be used in another embodiment to yield yet another embodiment. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention should fall within the scope of protection of the embodiments of the present invention.

[0026] During the processes of mining and coal mining, transfer equipment is installed in a section of the transportation gateway near the front of the coal - mining face. At both ends of the transfer equipment, a set of power equipment (motor and reducer) is respectively arranged at the same time. The transfer equipment and its power equipment occupy most of the roadway cross - section space. Especially in the height direction of the roadway, the space available for installing strengthening support equipment is often very small. Since there is coal transfer equipment in this area, large - scale advanced support equipment cannot be used. Currently, multiple hydraulic single props or cribbing supports are mostly manually installed for strengthening support. As the coal - mining face advances continuously, the props or supports at the proximal end need to be withdrawn and transported to the distal end of the prop or support queue. After being re - installed after being aligned with the props or supports at the most distal end, the purpose of advanced support can be achieved.

[0027] In the aspects of withdrawing, transporting forward and re-erecting a single hydraulic prop, manual operation is adopted. On the one hand, in the processes of withdrawing and erecting, multiple people need to cooperate, and there is a potential safety hazard of the single hydraulic prop toppling and injuring people. On the other hand, during the transportation process, the labor intensity is high, the efficiency is low, and as the roadway height increases, the weight of the prop will increase accordingly, resulting in increasing difficulty in manual handling.

[0028] Based on this, the present application provides a corner hydraulic prop handling device, as Figure 1 、 Figure 2 shown. The corner hydraulic prop handling device for handling and transferring the hydraulic props in the supported roadway includes: a side-mounted base 100 and a swing telescopic arm 200 rotatably installed on the side-mounted base 100. Among them, the side-mounted base 100 is installed on the side of the transfer equipment arranged in the roadway and can move along the roadway trend (the first direction) and the roadway height direction (the second direction), driving the swing telescopic arm 200 to move; by using the telescopic movement and swing of the swing telescopic arm 200, the grasping, transferring and placing of the hydraulic prop can be realized in the narrow and limited roadway cross-section space.

[0029] In the present application, a transverse movement track 101 extending along the first direction is installed on the side of the transfer equipment (the second transfer loader). The side-mounted base 100 is installed on the transverse movement track 101 and forms a gear-rack mechanism with the transverse movement track 101, so as to realize the movement of the side-mounted base 100 along the roadway trend on the transverse movement track 101. Specifically, a transverse movement chute is arranged on the transverse movement substrate 104 of the side-mounted base 100. The transverse movement chute is slidably sleeved on the transverse movement track 101, and a transverse movement driving unit 103 (a servo motor or a motor) is installed on the transverse movement substrate 104. The driving gear installed at the output end of the transverse movement driving unit 103 is adapted to the rack 102 on the transverse movement track 101 to form a gear-rack mechanism. Furthermore, driven by the transverse movement driving unit 103, the transverse movement substrate 104 can move along the roadway trend on the transverse movement track 101.

[0030] An elevating slide rail extending along the roadway height direction is further arranged on the transverse movement substrate 104. An elevating chute adapted to the elevating slide rail is arranged on the elevating substrate 105 of the side-mounted base 100. Furthermore, the elevating substrate 105 is driven by an elevating driving oil cylinder 106 to move along the roadway height direction on the transverse movement substrate 104. Among them, the elevating chute penetrates through the elevating substrate 105 along the second direction and is slidably sleeved with the elevating slide rail by adopting a dovetail cross-section structure; the cylinder body of the elevating driving oil cylinder 106 is connected to the transverse movement substrate 104, and the lever of the elevating driving oil cylinder 106 is connected to the elevating substrate 105.

[0031] A rotating mounting earplate is provided on the lifting substrate 105. The tail of the swing telescopic arm 200 is rotatably connected to the rotating mounting earplate through a rotating shaft and is driven by a rotary drive motor 201 to achieve left - right swing in the horizontal plane relative to the side - hanging base 100. Among them, the rotary drive motor 201 is installed on the outside of the rotating mounting earplate, the swing telescopic arm 200 is installed between two rotating mounting earplates, and the output end of the rotary drive motor 201 is coaxial with the rotating shaft to drive the swing telescopic arm 200 to swing around the rotating shaft, so that the swing telescopic arm 200 realizes a swing within the angular range of [0°, 180°] in the horizontal plane relative to the side - hanging base 100.

[0032] In a specific example, the swing telescopic arm 200 includes: a fixed part 202 and a telescopic part 203. The tail end of the fixed part 202 is rotatably connected to the rotating mounting earplate through a rotating shaft, and the tail end of the telescopic part 203 is slidably sleeved in the fixed part 202 from the other end of the fixed part 202. Here, both the fixed part 202 and the telescopic part 203 are hollow shell structures with a rectangular cross - section, and the aspect ratio of the width to the height of the hollow rectangle of the fixed part 202 and the telescopic part 203 is less than 1 to effectively improve the bending resistance of the swing telescopic arm 200.

[0033] A swing drive cylinder is installed in the hollow rectangles of the fixed part 202 and the telescopic part 203. Specifically, the cylinder barrel of the swing drive cylinder is rotatably installed in the hollow rectangular structure of the fixed part 202 through a pin shaft, and the lever of the swing drive cylinder is rotatably installed in the hollow rectangular structure of the telescopic part 203 through a pin shaft. Furthermore, under the action of the swing drive cylinder, the telescopic part 203 can perform telescopic sliding relative to the fixed part 202. In other specific examples, an electric push rod, a cylinder, etc. can also be used as the power to drive the telescopic part 203 to perform telescopic sliding relative to the fixed part 202; in addition, the swing drive cylinder, the electric push rod, the cylinder, etc. can also be arranged outside the swing telescopic arm 200.

[0034] A mechanical gripper is installed at the end of the telescopic part 203 for gripping the outer wall of the hydraulic prop. Specifically, the mechanical gripper includes two symmetrically arranged arc-shaped clamping members 204, and the outer wall of the hydraulic prop is held tightly by the inner walls facing each other of the two arc-shaped clamping members 204 to achieve the gripping of the hydraulic prop. Among them, the rear end of the arc-shaped clamping member 204 is rotatably installed at the end of the telescopic part 203, and the axis of the rotational connection extends along the height direction of the roadway. A self-resetting spring 206 is arranged between the arc-shaped clamping part and the telescopic part 203, and the two arc-shaped clamping members 204 are automatically held tightly against the hydraulic prop by the self-resetting spring 206. Here, the self-resetting spring 206 can adopt a torsion spring or a leaf spring. When a torsion spring is used, the torsion spring is coaxially arranged with the axis of the rotational connection of the arc-shaped clamping member 204. One end of the torsion spring is fixedly connected to the telescopic part 203, and the other end is fixedly connected to the arc-shaped clamping member 204. When a leaf spring is used as the self-resetting device of the arc-shaped clamping member 204, both ends of the leaf spring are respectively arranged on the outer walls of the telescopic part 203 and the arc-shaped clamping member 204.

[0035] When it is necessary to grip the hydraulic prop, accurate clamping of the hydraulic prop is achieved through the symmetrically arranged guiding members 205 provided at the front ends of the two arc-shaped clamping members 204. Specifically, the symmetrically arranged guiding members 205 on the two arc-shaped clamping members 204 are in an inverted V-shaped structure, and the opening of the inverted V-shaped structure of the guiding member 205 faces the hydraulic prop. When the telescopic part 203 moves outwards, the inverted V-shaped opening contacts the outer wall of the hydraulic prop, and the arc-shaped clamping member 204 expands outwards under the action of the hydraulic prop. As the telescopic part 203 continues to move outwards, the arc-shaped clamping member 204 holds tightly against the outer wall of the hydraulic prop under the action of the self-resetting spring 206.

[0036] Then, the lifting base plate 105 moves upward, the telescopic part 203 retracts inward, and swings at the same time, so that the hydraulic support is retracted close to the transport device; driven by the transverse base plate 104, it moves along the direction of the lane to realize the transport and transfer of the hydraulic support. The side-mounted base 100 installed on the side of the transfer equipment arranged in the tunnel moves along the direction and height direction of the tunnel, driving the swing telescopic arm 200 installed on the side-mounted base 100 to move, so that after grabbing the hydraulic pillar, the swing telescopic arm 200 can move along the direction and height direction of the tunnel to realize the transportation and transfer of the hydraulic pillar; the telescopic nesting structure of the swing telescopic arm 200 enables it to perform linear telescopic movement along its length direction, and then, in a small and limited space, the hydraulic pillar is grabbed and retracted by the mechanical gripper installed at the end, so as to effectively reduce the space occupied relative to the side of the tunnel, and the transportation and transfer of the hydraulic pillar is realized under the drive of the side-mounted base 100, and the grabbed hydraulic pillar is installed in an appropriate position by swinging the swing telescopic arm 200 left and right relative to the side-mounted base 100 in a horizontal plane. After the hydraulic pillar is extended and supports the top plate above, the mechanical gripper releases the hydraulic pillar, the swing telescopic arm 200 retracts inward, and swings again to return to the initial state. In this way, the hydraulic props can be flexibly transported and transferred in the narrow and limited cross-sectional space of the tunnel, and the efficiency of transport and transfer is improved, effectively eliminating the safety hazards caused by manual transport.
