Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

The utility model discloses a large-scale bearing replacement support, which is mainly used in the process of bearing replacement. The support can be used to lift the bearing conveniently and quickly, and then accurately and quickly connect the hole on the bearing seat with the case hole on the machine base. align. The utility model is especially suitable for replacing large and heavy bearings.

The bearing replacement bracket of the utility model is provided with a support seat 1, and a support mechanism is provided on the lower end surface of the support seat 1, and the support mechanism is used to lift the support seat 1 together with the shaft. There are many ways to set up the supporting mechanism in the specific implementation process, and the combination of the hydraulic cylinder 3 and the universal wheel 4 is preferentially used as the supporting mechanism. Both the hydraulic cylinder 3 and the universal wheel 4 are fixed on the lower end surface of the bracket seat 1 .

In the utility model, the bracket seat 1 is generally arranged as a rectangular block, and the material of the rectangular block is selected from steel or iron. One hydraulic cylinder 3 is respectively arranged at the four corners of the lower end surface of the bracket seat 1 rectangle, and one universal wheel 4 is respectively arranged at the four corners of the rectangular lower end surface of the bracket seat 1 . The setting of the universal wheel in the utility model can move the bearing replacement bracket conveniently, and the hydraulic cylinder is used for lifting the bracket seat. In the utility model, the cylinder barrel 3-1 of the hydraulic cylinder 3 is fixedly connected with the support seat 1. In the specific implementation process, the cylinder barrel 3-1 of the hydraulic cylinder 3 is generally fixed in the support seat 1. The specific structure is shown in the figure 1. Specifically, the mounting hole 1-3 for fixing the cylinder barrel 3-1 of the hydraulic cylinder 3 is provided on the lower end surface of the support seat 1, and the cylinder barrel 3-1 is fixed in the mounting hole 1-3, and the specific structure is shown in Figure 2 Show. The depth of the installation hole 1-3 is consistent with the length of the cylinder 3-1, ensuring that the end face of the cylinder 3-1 is flush with the lower end face of the bracket seat 1, so that the telescopic rod 3-2 can be recovered in the normal non-working state Only the shorter rod head part is exposed outside, which will not affect the transfer and storage of the bracket base 1 . When the support base 1 is transferred, the caster 4 plays a supporting role, and the telescopic rod 3-2 of the hydraulic cylinder 3 stretches out to contact the ground when lifting operations are required, and then the support base 1 is lifted to a required height. The universal wheel 4 of the utility model is limitedly configured as a universal wheel with a self-locking function to ensure that the bearing replacement support is in a stable state when not working.

In the utility model, the universal wheel 4 is preferably arranged on the inner side of the hydraulic cylinder 3, that is, the rectangle formed by the universal wheels 4 on the four corners is smaller than the rectangle formed by the hydraulic cylinders 3 on the four corners.
