It also acts as a supporting wheel to ensure the normal operation of the excavator's working performance and traveling performance, and plays a vital role in the safety of excavator operation. The existing guide wheel assembly of the excavator consists of a guide wheel and a tensioning device, which is usually not provided with a tie-down lifting lug for lifting. It needs to be tied or bound with a wire rope during lifting. In this lifting method, the center of gravity of the guide wheel assembly is offset, and it is difficult to ensure that the tensioning device remains horizontal during lifting, which brings inconvenience to the installation of the guide wheel assembly. In addition, the lifting rope is easy to wear. It is difficult to firmly tie the guide wheel assembly with a lifting rope, which does not meet safety requirements, has safety hazards, does not meet ergonomics, and is difficult and inefficient to lift with a lifting rope, affecting production efficiency.

[0022] The specific implementation scheme is described below with reference to the accompanying drawings.

[0023] In this embodiment, the directions of "front", "rear", "left", "right", "up" and "down" are based on the lifting tool. Figure 1 The status in is the reference benchmark.

[0024] like Figure 1 As shown, the lifting tool in this embodiment is used for lifting the guide wheel assembly, and includes a lifting rod 10, the lifting rod 10 has a horizontal section 11 extending forward and backward, and a lifting hole 110 is provided on the horizontal section 11. The lifting hole 110 is used to be tied with a lifting rope or a sling.

[0025] At the rear end of the horizontal section 11, there is a downward extending section 12 extending downward, and two clamping plates 14 extending to the left and right sides below the horizontal section 11 are provided on the downward extending section 12. The two clamping plates 14 are parallel to each other and the front ends are both provided with a clamping groove 141 for the guide wheel mounting arm to slide horizontally from front to rear; there is a gap space between the two clamping plates 14 to accommodate the guide wheel in the guide wheel.

[0026] Optionally, the horizontal section 11 and the downwardly extending section 12 are transitionally connected by an arc section 13. The suspension rod 10 is plate-shaped, and the width of the suspension rod 10 in the radial direction of the guide wheel of the guide wheel assembly is greater than the width of the suspension rod 10 in the left-right direction (the thickness of the steel plate used to make the suspension rod). The suspension rod 10 can be formed by cutting a steel plate.

[0027] Optionally, there are multiple lifting holes 110 provided on the horizontal section 11, and the lifting holes 110 are arranged at intervals in the front-rear direction. When lifting the guide wheel assembly 2, the corresponding lifting hole 110 can be selected according to the center of gravity position after the guide wheel assembly 2 is connected to the lifting tool 1, so that when the horizontal section 11 of the suspension rod 10 is in a horizontal state, the center of gravity is located completely below the selected lifting hole 110.

[0028] Optionally, baffles 15 extending to the left and right sides are welded on the downward extension section 12, and the clamping plate 14 is welded to the left end or right end of the corresponding baffle 15. The two baffles 15 located on the left and right sides of the downward extension section 12 can be two pieces, or they can be composed of a single integrated plate, which is welded to the front side of the downward extension section 12.

[0029] Optionally, the clamping plates 14 and baffles 15 located on the left and right sides of the suspension rod 10 can also be formed by an integrated structure of a steel plate bent into a U shape. By bending a whole steel plate to form two clamping plates 14 and two baffles 15, the length of the weld can be reduced.

[0030] Optionally, a plurality of reinforcing ribs 16 are welded between the rear side surfaces of the left and right side surfaces of the baffles 15 and the corresponding side surfaces of the left and right side surfaces of the downward extending section 12 to strengthen the connection strength between the baffles 15 and the downward extending section 12. Furthermore, a support plate 17 is welded to the top of each baffle 15, and the side of the support plate 17 opposite to the suspension rod 10 is welded to the suspension rod 10. Reinforcing plates 18 are vertically welded to the left and right side surfaces of the rear end of the horizontal section 11, and the top ends of the left and right support plates 17 are welded to the rear side surfaces of the reinforcing plates 18 on the corresponding sides.

[0031] Optionally, a handle 19 is welded on the rear side of the arc segment 13. When the guide wheel assembly 2 is hoisted, the handle 19 can be held to stabilize the hoisting tool 1, prevent the hoisted guide wheel assembly 2 from shaking, and improve stability.

[0032] like Figure 2 As shown, the guide wheel assembly 2 is composed of a guide wheel 21 and a tensioning device 20. The tensioning device 20 includes a wheel seat 22. The wheel seat 22 has two guide wheel mounting arms. The guide wheel 21 is mounted between the two guide wheel mounting arms of the wheel seat 22 through a pin shaft. The guide wheel assembly 2 is used for crawler walking equipment, such as an excavator. The guide wheel mounting arms on both sides of the wheel seat 22 are block-shaped. When the guide wheel assembly 2 is hoisted, the guide wheel mounting arms on both sides of the wheel seat 22 are correspondingly inserted into the slots 141 of the left and right side clamps 14. In the guide wheel assembly 2, the weight of the guide wheel 21 occupies most of the weight, and the center of gravity of the guide wheel assembly 2 is located near the center of the guide wheel. When the wheel seat 22 is inserted into the slot 141, the center of gravity of the guide wheel assembly 2 is located below the horizontal section 11 of the suspension rod 10. The lifting rope is tied to the corresponding lifting hole 110 on the horizontal section 11 for lifting, and the lifting tool 1 and the guide wheel assembly 2 can be lifted smoothly. The guide wheel assembly 2 is hoisted in this posture, which is convenient for installing the guide wheel assembly 2 on the excavator. The connection and disassembly of the hoisting tool 1 and the guide wheel assembly 2 are also convenient and simple.
