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.

[0025] The specific implementation scheme is described below with reference to the accompanying drawings.

[0026] like Figure 3 As shown, the guide wheel assembly 200 includes a wheel seat 220 and a guide wheel 210. The wheel seat 220 includes a wheel seat body 222 and two guide wheel mounting arms 221 extending forward from the wheel seat body 222 for connecting the guide wheel 210. The guide wheel assembly 200 is used for crawler walking equipment, such as an excavator.

[0027] The lifting tool 100 is used to be placed between the two guide wheel mounting arms 221 in the guide wheel assembly 200 to lift the guide wheel assembly 200. The lifting tool 100 includes:

[0028] The first main body 10 has a lifting lug 5 disposed on its top and a recessed portion 111 on its front side that can cooperate with the wheel surface of the guide wheel 210; the lifting lug is used to be connected to the sling bolt.

[0029] The second body 20 is rotatably connected to the first body 10 in a cross shape through a left-right connecting pin shaft 3. The lower part of the second body 20 is provided with a lifting part 21 extending backward and capable of contacting the bottom surface of the wheel seat body 222;

[0030] The locking device 4 is detachably arranged between the top of the first body 10 and the top of the second body 20, and is used to lock and fix the first body 10 and the second body 20 relative to each other.

[0031] like Figure 1 Figure 2 As shown, the first body 10 and the second body 20 are basically rigid parts extending up and down. In one embodiment, the first body 10 includes main boards 11 arranged vertically at intervals on the left and right, and a top plate 12 connecting the two main boards 11, and the ear 5 is set on the top plate 12; the second body 20 is arranged between the two main boards 11 and is rotatably connected by the connecting pin 3. The second body 20 can be a rod-shaped or long strip-shaped component, which can rotate around the connecting pin 3, and the second body 20 and the main board 11 in the first body 10 are approximately cross-connected in an X shape.

[0032] A support 6 is provided on the top plate 12, and the locking device 4 includes a locking rod 41 and a bolt portion 42 fixedly arranged on the top of the second main body 20. The rear end of the locking rod 41 is rotatably connected to the support 6 through a locking pin shaft 44 extending left and right, and a card slot 411 for the bolt portion 42 to be embedded is provided on the lower side surface of the front part of the locking rod 41.

[0033] Optionally, there are two locking rods 41 and they are arranged in parallel on the left and right sides, and the two locking rods 41 are arranged on the left and right sides of the support 6 respectively. The locking device 4 also includes a connecting rod 43, which is arranged between the two locking rods 41 and fixedly connected to the locking rods 41 at both ends. The connecting rod 43 connects the two locking rods 41 into a rigid body, and the two locking rods 41 rotate synchronously around the locking pin 44. The bolt part 42 is a horizontal rod-shaped component running left and right, and the middle part is fixedly connected to the second body 20. The locking pin 44 can be composed of a bolt and a nut.

[0034] Optionally, the lifting ear 5 is plate-shaped and arranged in a front-to-back direction, and a plurality of lifting holes 51 arranged at intervals in the front-to-back direction are provided on the lifting ear 5. The lifting ear 5 is fixedly mounted on the support 6 by a lifting ear mounting bolt 53. Optionally, two or more lifting ear mounting holes 52 for cooperating with the lifting ear mounting bolt 53 are provided on the lifting ear 5, and each lifting ear mounting hole 52 is arranged at intervals in the front-to-back direction. The lifting ear 5 can select two adjacent lifting ear mounting holes 52 to cooperate with the lifting ear mounting bolt 53 to achieve its installation. By selecting the lifting ear mounting holes 52 at different positions to cooperate with the lifting ear mounting bolt 53 on the support 6, the position of the lifting ear 5 in the front-to-back direction can be adjusted, which is convenient for adjusting the position of the tie-down point according to the center of gravity when the guide wheel assembly 200 is hoisted.

[0035] like Figure 1 Figure 2 As shown, the front side of the main board 11 is bent in a bracket shape, thereby forming a recessed portion 111 on the front side of the first body 10. When the recessed portion 111 is matched with the wheel surface of the guide wheel 210, there are at least two contact points in the circumferential direction of the wheel surface. When the first body 10 does not move in the radial direction relative to the guide wheel 210, the first body 10 and the guide wheel 210 cannot move.

[0036] like Figure 3 Figure 4 As shown, when the lifting tool 100 is used to lift the guide wheel assembly 200, the lifting tool 100 is inserted into the guide wheel assembly 200 and is located at the rear side of the guide wheel 210. The recessed portion 111 on the front side of the first body 10 cooperates with the wheel surface of the guide wheel 210, and the second body 20 is rotated relative to the first body 10, so that the lifting portion 21 at the lower part of the second body 20 moves backward and extends to the bottom of the wheel seat body 222, and the locking rod 41 is rotated to insert the bolt portion 42 at the top of the second body 20 into the card slot 411 of the locking rod 41, so that the first body 10 and the second body 20 are relatively fixed. The operation is as follows: Figure 4 As shown by the arrow in the middle. Selecting a suitable lifting hole 51 to connect with the lifting rope can realize the lifting of the guide wheel assembly 200. When it is necessary to remove the connection between the lifting tool 100 and the guide wheel assembly 200, after releasing the locking device 4 from the first body 10 and the second body 20, the second body 20 is rotated relative to the first body 10, and the lifting part 21 at the lower part of the second body 20 is separated from the wheel seat body 222, the lifting tool 100 can be taken out.

[0037] The lifting tool in this embodiment lifts the guide wheel assembly, and the connection and disassembly of the lifting tool and the guide wheel assembly are convenient, and the connection is firm and safe.
