Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering and relates to a travelling hammer type end bearing installation and removal tool. Background Art

[0002] In the actual inspection and maintenance process of the end bearing, in order to prevent the uneven force on the bearing end face, which may cause local damage and brittle cracking of the bearing, it is particularly important to protect the bearing and increase the force. Therefore, the utility model is manufactured to reduce the uneven force on the bearing end face during the process and prevent local damage and brittle cracking of the bearing. Utility Model Content

[0003] The utility model aims to provide a movable hammer type end bearing installation and removal tool to solve the problem that the end face of the end bearing is not subjected to balanced force during the inspection and maintenance of the end bearing, resulting in local damage and brittle cracking of the bearing.

[0004] To this end, the utility model adopts the following technical solutions:

[0005] A travelling hammer type end bearing installation and removal tool, characterized in that it includes a horizontally arranged bearing, a sleeve is provided on the top of the bearing, a column is provided in the middle of the sleeve, a travelling hammer is provided on the outside of the column, guide rods are symmetrically provided on both sides of the travelling hammer, one end of the guide rod is fixedly connected to the sleeve, and the other end is passed through by the travelling hammer, and a fixing nut is provided at the end of the guide rod.

[0006] Furthermore, the movable hammer can perform horizontal reciprocating movement along the column.

[0007] Furthermore, the traveling weight comprises a first circular ring and a second circular ring, and the guide rail rod passes through the first circular ring.

[0008] The beneficial effects of the utility model are:

[0009] During use, the utility model can reduce the problem of uneven force on the end face of the bearing during operation, prevent the bearing from being partially damaged or brittle, and reduce the work intensity of maintenance personnel. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural schematic diagram of the utility model;

[0011] In the figure, 1-bearing, 2-sleeve, 3-guide rod, 4-travelling weight, 4a-first circular ring, 4b-second circular ring, 5-column, 6-fixing nut. DETAILED DESCRIPTION

[0012] The technical solution of the utility model is described below in conjunction with the accompanying drawings and implementation methods.

[0013] like Figure 1 As shown, a travelling hammer type end bearing installation and removal tool comprises a horizontally arranged bearing 1, a sleeve 2 is arranged on the top of the bearing 1, a column 5 is arranged in the middle of the sleeve 2, and a travelling hammer 4 is arranged on the outside of the column 5.

[0014] The traveling hammer 4 includes a first circular ring 4a and a second circular ring 4b, wherein the radius of the first circular ring 4a is greater than the radius of the second circular ring 4b; the traveling hammer 4 can reciprocate horizontally along the column 5, and guide rods 3 are symmetrically arranged on both sides of the traveling hammer 4, wherein one end of the guide rod 3 is fixedly connected to the sleeve 2, and the other end passes through the first circular ring 4a.

[0015] In addition, a fixing nut 6 is provided at the end of the guide rail rod 3, and the fixing nut 6 plays a limiting role.

[0016] The use process of this utility model is as follows:

[0017] First, fix the sleeve 2 to the inner ring end face of the bearing 1. Then, use the movable hammer 4 to hammer down or up along the guide rod 3 by applying appropriate force to apply force to the inner ring of the bearing 1 to achieve the purpose of installing and disassembling the bearing, ensuring the safety of maintenance personnel and the requirements for bearing crack prevention.
