Technical Field

[0001] The utility model relates to the technical field of guide wheel shaft sleeve installation, in particular to a guide wheel shaft sleeve installation device. Background Art

[0002] The guide wheel is also called the guide wheel, which is used to guide the crawler to rotate correctly to prevent the crawler from running off the track. In addition, the guide wheel tightens the crawler through the tensioner and buffers the impact of external loads on the whole machine.

[0003] At present, the guide wheels have different sizes depending on the type of engineering machinery used. During the assembly of the guide wheels, sleeves need to be installed at both ends of the shaft to increase the wear resistance of the shaft. In order to improve the installation efficiency of the sleeves, the general installation method is to place the guide wheels vertically, and then press the two sleeves onto the shaft at the same time through the tooling.

[0004] However, since the size of each type of guide wheel is different, when placed vertically, the height between the axis and the ground is different, and the existing sleeve installation equipment has a fixed height for installing the sleeve, which can only be used for the installation of large quantities of guide wheels with the same diameter, but not for the installation of sleeves of guide wheels with different diameters.

[0005] Therefore, the utility model proposes a guide wheel shaft sleeve installation device, which is suitable for installing the shaft sleeve of guide wheels with different diameters. Utility Model Content

[0006] In view of the above technical problems, the utility model provides a guide wheel sleeve installation device, which is used to solve the problem that the height of the sleeve installed in the existing sleeve installation equipment is fixed, and it can only be used for the installation of large quantities of guide wheels with the same diameter, but cannot be used for the installation of guide wheels with different diameters.

[0007] The above technical objectives of the utility model are achieved through the following technical solutions:

[0008] A guide wheel sleeve installation device comprises a base, a gantry is arranged on the base, a cantilever is arranged inside the gantry, the gantry comprises a guide column fixed on the base, a crossbeam is arranged on the guide column in a horizontal and vertical manner and slidingly, the cantilever is connected to the crossbeam, a first oil cylinder is arranged at the other end of the crossbeam, a support column is arranged at the output end of the first oil cylinder, and the support column is fixed on the base;

[0009] An accommodating opening is provided through the middle of the cantilever, and two second oil cylinders are symmetrically provided on both sides of the cantilever at the accommodating opening, and the two second oil cylinders move towards each other.

[0010] Furthermore, a pressing sleeve is detachably mounted on the output end of the second oil cylinder.

[0011] Furthermore, a sliding sleeve is provided at the joint between the cross beam and the guide column.

[0012] Furthermore, a V-shaped placement groove is provided at the position of the base located at the accommodating opening.

[0013] Furthermore, the guide column and the base are detachably connected.

[0014] Furthermore, the crossbeam and the cantilever are detachably connected.

[0015] Furthermore, the end of the output end of the second oil cylinder is tapped with an external thread, and the compression sleeve is threadedly connected to the output end of the second oil cylinder.

[0016] In summary, the beneficial technical effects of the utility model are:

[0017] (1) The guide wheel is placed vertically in the receiving opening of the cantilever using the base. According to the height position of the guide wheel axle, the first oil cylinder drives the crossbeam to slide up and down along the guide column so that the output ends of the two second oil cylinders are in a concentric position with the axle of the guide wheel. The two bushings are simultaneously pressed into the axle of the guide wheel by the second oil cylinder for installation. Therefore, the height of the two second oil cylinders is adjusted by the sliding cooperation between the first oil cylinder, the crossbeam and the guide column, thereby enabling the installation of bushings for guide wheels of different sizes.

[0018] (2) The use of the sliding sleeve improves the stability of the sliding of the beam on the guide column on the one hand, and reduces the friction between the beam and the guide column on the other hand, avoiding the problem of jamming.

[0019] (3) The threaded connection between the output end of the second oil cylinder and the pressing sleeve facilitates replacement of the corresponding pressing sleeve according to the size of the shaft sleeve. BRIEF DESCRIPTION OF THE DRAWINGS
