The hydraulic walking motor driving assembly is heavy in quality, and its installation needs to use a lifting appliance for hoisting. During hoisting, the stability and safety of the hydraulic walking motor driving assembly need to be ensured. In the prior art, a lifting hook or a binding belt is mainly used for hoisting. When the lifting hook is used for hoisting, the lifting hook can directly pass through the threaded hole of the hydraulic walking motor, thereby realizing the hoisting of the hydraulic walking motor driving assembly. However, the lifting hook passing through the threaded hole of the hydraulic walking motor may damage the threads of the threaded hole, resulting in assembly errors and installation connection strength of the hydraulic walking motor driving assembly. When the binding belt is used for hoisting, the binding belt is wound around some parts of the hydraulic walking motor driving assembly, and then the hydraulic walking motor driving assembly is hoisted by tightening the binding belt. In this way, the center of gravity of the hydraulic walking motor driving assembly is easy to deviate, and the hydraulic walking motor driving assembly is easy to fall during hoisting, which may cause personal injury and safety hazards.

[0018] Figure 2 is the connection schematic view of the hydraulic walking motor driving assembly lifting appliance of the utility model and the hydraulic walking motor driving assembly.

[0019] Names and serial numbers of parts in the drawing:

[0020] C-shaped hoop 10, hoop 11, extension 111, locking part 12, nut block 13, rubber pad 14, convex texture 141.

[0021] Lifting ring 20, fixed lifting ring seat 21, vertical bar 211, horizontal bar 212, movable lifting ring seat 22, ear 23, pin shaft 24.

[0022] Screw 30.

[0023] Hydraulic travel motor drive assembly lifting device 100, hydraulic travel motor drive assembly 200. Detailed Implementation

[0024] The specific implementation plan is described below with reference to the attached diagram.

[0025] like Figure 1 As shown, the hydraulic travel motor drive assembly lifting device 100 includes a C-shaped clamp 10, a lifting ring 20, and a locking device.

[0026] The C-shaped clamp 10 has its opening facing downwards, and the lifting ring 20 is located on the top of the C-shaped clamp 10.

[0027] The locking device includes a screw 30, with both ends of the screw 30 rotatably connected to the openings of the C-shaped clamp 10, and at least one end being threadedly connected. The rotatable connection means that when the screw is not rotated, it restricts the opening of the C-shaped clamp 10 from opening; when the screw is rotated, the opening of the C-shaped clamp 10 moves in the axial direction of the screw, tightening or opening accordingly. Rotating the screw 30 in the forward direction tightens the opening of the C-shaped clamp 10, allowing it to grip the hydraulic travel motor located within it. Rotating the screw 30 in the reverse direction opens the opening of the C-shaped clamp 10, allowing it to slide along the axial direction of the hydraulic travel motor and disengage from it. In this embodiment, the connection and disconnection between the hydraulic travel motor drive assembly lifting device 100 and the hydraulic travel motor assembly 200 are convenient and the connection is secure after connection.

[0028] Optionally, both ends of the screw 30 are threaded with opposite helical directions, and both ends of the opening of the C-shaped clamp 10 are fixed with nut blocks 13 that mate with the threads at both ends of the screw 30. The screw 30 has threads with opposite helical directions at both ends, and rotating the screw 30 allows for faster tightening or loosening of the opening of the C-shaped clamp 10, thereby achieving quick connection and disconnection.

[0029] Optionally, the C-shaped clamp 10 includes a clamp band 11 and locking portions 12 fixed to both ends of the clamp band, with nut blocks 13 fixed to the locking portions 12. The locking portions 12 are buckle-shaped and have receiving holes for accommodating the nut blocks 13. Further, the end of the clamp band 11 has an extension portion 111 extending in an arc direction to the other end, with the extension portion 111 located above the corresponding locking portion 12. The extension portion 111 reduces the gap at the opening when the clamp band 11 locks the hydraulic travel motor, while ensuring sufficient gap between the locking portions 12 at both ends for easy locking operation.

[0030] Optionally, the nut block 13 is cylindrical, and the axis of the threaded hole on the nut block 13 is perpendicular to the center line of the nut block 13. After the screw rod 30 is disengaged from the nut block 13, the nut block 13 can be moved axially to disengage from the locking portion 12.

[0031] Optionally, the inner side of the hoop 11 opposite to the side provided with the rubber pad 14 is provided with a protruding texture 141 for preventing slipping. The hoop 11 is usually made of steel, and the rubber pad 14 is arranged on the inner side of the hoop 11 to avoid the hard contact between the steel hoop 11 and the hydraulic traveling motor, which can cause damage to the surface of the hydraulic traveling motor.

[0032] Optionally, the lifting ring 20 includes a fixed lifting ring seat 21 and a movable lifting ring seat 22. The lower part of the fixed lifting ring seat 21 is fixedly connected to the arc-shaped top of the hoop 11. The movable lifting ring seat 22 is rotatably connected to the top of the fixed lifting ring seat 21 by a pin shaft 24. A lifting lug 23 is arranged at the central position of the top of the movable lifting ring seat 22. The fixed lifting ring seat 22 includes a plurality of vertical strips arranged at intervals and fixedly connected to the hoop 11 at the lower end in the length direction of the hoop 11. The top of each vertical strip 211 is fixedly connected to a horizontal strip 212. The top of each of the two vertical strips 211 located at the most side is connected to the movable lifting ring seat 22 by a pin shaft 24.

[0033] In this embodiment, when the lifting device lifts the hydraulic traveling motor driving assembly 200, the screw rod 30 is reversely rotated to expand the opening of the C-shaped hoop 10, and the C-shaped hoop 10 is sleeved on one end of the hydraulic traveling motor, as shown in Figure 2 After the screw rod 30 is forwardly rotated, the C-shaped hoop 10 is locked, and the C-shaped hoop 10 is fixedly connected to the hydraulic traveling motor. This connection mode makes the hydraulic traveling motor driving assembly 200 firm, safe and reliable during lifting, and the connection and disconnection of the lifting device and the hydraulic traveling motor driving assembly is convenient.
