Description

Technical Field

[0001] The utility model belongs to the technical field of cranes, and in particular relates to a horizontal wheel device for cranes. Background Art

[0002] Crane refers to a multi-action lifting machine that can lift and carry heavy objects vertically and horizontally within a certain range. It is also called overhead crane, overhead crane, and crane. In order to improve the sliding stability of the crane, horizontal wheels need to be installed at both ends of the crane's traveling mechanism.

[0003] When the existing horizontal wheel device for crane is in use, the horizontal wheels are directly installed at both ends of the traveling mechanism, and the horizontal wheels will wear when working, resulting in a larger gap between the horizontal wheels and the guide rails. After long-term use, the horizontal wheels are easily separated from the guide rails. In view of this, we propose a horizontal wheel device for crane. Utility Model Content

[0004] The utility model aims to solve the above-mentioned technical problems and provide a horizontal wheel device for a crane, so as to avoid the problem that the horizontal wheel is easily separated from the guide rail after long-term use.

[0005] In view of this, the utility model provides a horizontal wheel device for a crane, comprising a mounting frame, bolts are provided on both side outer walls of the mounting frame, connecting slide plates are threadedly connected to the outer walls of the bolts, both ends of the connecting slide plates are fixedly connected to positioning hole plates slidably connected to the outer walls of the mounting frame, the bottom end of the positioning hole plates is slidably connected to a limiting strip fixedly connected to the outer wall of the mounting frame, a connecting slide groove is provided at one end of the positioning hole plates, a connecting slide groove is movably connected to a connecting column on the inner wall, an adjusting slide groove is provided at the connecting portion between the mounting frame and the connecting column, a horizontal roller is sleeved on the outer wall of the connecting column, a connecting gasket is sleeved on the outer wall of the horizontal roller, and a guide rail is rollingly connected to the outer wall of the connecting gasket;

[0006] A lubrication assembly is located inside the mounting frame and is used to automatically add lubricating oil to the connection gasket.

[0007] Based on the above structure, the rotation of the bolt drives the positioning hole plates connecting the two ends of the sliding plate to slide along the outer wall of the limiting strip through the thread, and the sliding of the positioning hole plates drives the connecting column to slide along the outer wall of the adjusting groove through the connecting groove. By setting two groups of adjusting grooves distributed in an eight-shaped pattern, it is beneficial for the sliding of the connecting column to drive the connecting gasket on the outer wall of the horizontal roller to fit closely with the guide rail, thereby preventing the horizontal roller from detaching from the guide rail.

[0008] Preferably, the connecting column forms a sliding structure between the connecting slide groove and the adjusting slide groove.

[0009] Preferably, two groups of connecting grooves are provided, and the two groups of connecting grooves are distributed in an eight-shaped shape.

[0010] Preferably, the cross section of the horizontal roller is I-shaped.

[0011] Preferably, the lubrication assembly comprises:

[0012] A lubrication frame, wherein a lubrication frame fixedly connected to the outer wall of the connecting column is arranged inside the mounting frame, a lubrication block fitted with the outer wall of the connecting gasket is fixedly connected to the inner wall of the lubrication frame, a support plate is fixedly connected to the top of the mounting frame, a mounting plate is fixedly connected to one end of the mounting frame, and a cleaning brush slidably connected to the outer wall of the guide rail is fixedly connected to the outer wall of the mounting plate.

[0013] Preferably, two groups of lubricating blocks are provided, and the connection parts between the lubricating blocks and the connection gaskets are in an arc shape.

[0014] Preferably, the cross-section of the working surface of the cleaning brush is the same as the cross-section of the guide rail.

[0015] The beneficial effects of the utility model are:

[0016] 1. The horizontal wheel device for the crane is provided with an adjusting slot. The bolt rotates through the thread to drive the positioning hole plates connected to both ends of the slide plate to slide along the outer wall of the limit strip. The positioning hole plates slide through the connecting slots to drive the connecting column to slide along the outer wall of the adjusting slot. By providing two groups of adjusting slots distributed in an eight-shaped pattern, it is beneficial for the connecting column to slide and drive the connecting gasket on the outer wall of the horizontal roller to fit closely with the guide rail, thereby preventing the horizontal roller from being separated from the guide rail.

[0017] 2. The crane uses a horizontal wheel device, which is equipped with a lubrication block. The sliding of the mounting frame drives the cleaning brush on the outer wall of the mounting plate to slide along the outer wall of the guide rail to clean the dust attached to the outer wall of the guide rail. At the same time, the horizontal roller rolls along the outer wall of the guide rail, and the horizontal roller rolls relative to the lubrication block on the inner wall of the lubrication frame to automatically lubricate the connecting gasket on the outer wall of the horizontal roller to avoid serious wear of the connecting gasket.

[0030] In one embodiment, the connecting column 7 forms a sliding structure by connecting the sliding groove 6 and the adjusting sliding groove 8 .

[0031] In this embodiment, the positioning hole plate 4 slides through the connecting slide groove 6 to drive the connecting column 7 to slide along the outer wall of the adjusting slide groove 8, thereby realizing the sliding operation of the connecting column 7.

[0032] In one embodiment, two groups of connecting grooves 6 are provided, and the two groups of connecting grooves 6 are distributed in an eight-shaped shape.

[0033] In this embodiment, two groups of adjusting grooves 8 distributed in an eight-shaped manner are provided, which facilitates the sliding of the connecting column 7 to drive the connecting gasket 10 on the outer wall of the horizontal roller 9 to fit closely with the guide rail 11.

[0034] In one embodiment, the cross section of the horizontal roller 9 is in an I-shape.

[0035] In this embodiment, by providing a horizontal roller 9 with an I-shaped cross section, it is beneficial to improve the stability of the connection between the horizontal roller 9 and the guide rail 11.
