Preferably, a reinforced fixing structure is provided between the middle part of the counterweight and the base, specifically: several diagonal braces are arranged between the side wall of the counterweight and the base, and the upper end of each brace is connected to the counterweight. The middle side wall is welded and fixed, and the lower end is welded and fixed with the base.

Preferably, triangular reinforcing ribs are welded between the inner sides of the two lifting lugs of the first lifting lug set and the third lifting lug set and the base.

Beneficial effects of the utility model: 1. When in use, the driver's cab is fixed on the driver's cab supporting area of the base, and the lifting point formed by the fixed-length steel wire rope group and the upper end of the chain hoist group is used to connect with the lifting device hook, and then the whole base is connected with the The driver's cab is hoisted to the outside of the installation position of the tire crane's cab, and the driver's cab support area of the base is extended into the installation position, and then the driver's cab and the frame of the tire crane are connected and fixed. The use of this tool prevents the driver's cab from The small frame interferes so that the installation can proceed smoothly; 2. After installing the driver's cab on the tire crane, readjust the center of gravity of the entire tooling through the chain hoist to ensure the safety of the tooling when it is put down. 3. The chain hoist can be used to adjust the center of gravity corresponding to different types of cabs, which has a wide range of applications and small limitations.

Detailed ways

Example 1

The hoisting tooling for the cab of the tire crane in this embodiment mainly includes a base 1, a counterweight 2, a fixed-length wire rope group, and a chain hoist group.

As shown in Figures 1, 2, 3 and 4, the base 1 is a rectangular frame structure composed of several transverse bars and several longitudinal bars. In this embodiment, the base 1 has an overall length of 6000 mm and a width of 2400 mm. The base 1 is divided into a counterweight area on the left side and a driver's cab support area on the right side. On both sides of the base 1 along its long axis, a first lifting lug group 11, a second lifting lug group 12, a third lifting lug group Lifting lug group 13 and fourth lifting lug group 14, wherein the first lifting lug group 11 and the third lifting lug group 13 are the lifting lug groups for lifting, the second lifting lug group 12 and the fourth lifting lug group 14 are fixed to the cab Use lugs. Triangular reinforcing ribs 17 are welded between the inner sides of the two lifting lugs of the first lifting lug set 11 and the third lifting lug set 13 and the base.

As shown in FIG. 5 , the counterweight 2 is placed in the counterweight area of the base 1 , and counterweight limit stops 15 are provided on the base 1 around the bottom of the counterweight 2 . In order to ensure safety during the lifting process, a reinforced fixing structure is provided between the middle of the counterweight 2 and the base 1, specifically: several diagonal braces 16 are arranged between the side wall of the counterweight and the base, and each diagonal brace The upper end of 16 is welded and fixed with counterweight 2 middle part side walls, and the lower end is welded with base 1 and fixed.

The fixed-length steel wire rope group includes two fixed-length steel wire ropes 3, and the lower ends of the two fixed-length steel wire ropes 3 are respectively connected with the two lifting lugs of the first lifting lug group 11; The lower ends of the chain hoists 4 are respectively connected with the two lifting lugs of the third lug group 13, and the upper ends of the two hand chain hoists 4 are connected and fixed with the upper ends of the two fixed-length steel wire ropes 3 to form a lifting point for lifting.

working principle:

Fix the driver's cab on the driver's cab supporting area of the base 1, and connect the lifting point formed by the fixed-length steel wire rope group and the upper end of the chain hoist group to the hook of the lifting device; hoist the entire base 1 together with the driver's cab to the driver's cab of the tire crane Outside the installation position, extend the driver's cab support area of the base 1 into the installation position, and then connect and fix the driver's cab with the frame of the tire crane.

After the installation is completed, the center of gravity of the entire tooling changes due to the detachment of the driver's cab, as shown in Figure 6. It is necessary to adjust the chain block to ensure that the base is still in a balanced state, and then put down the base.
