Description

Technical Field

[0001] This invention relates to the field of crane rail technology, specifically to a conveniently detachable and assembled explosion-proof crane travel rail and its usage method. Background Technology

[0002] Explosion-proof hoist bridge crane, or simply "explosion-proof crane", is a double-girder bridge crane that uses an explosion-proof electric hoist as its lifting mechanism. It is technologically mature, reliable, simple in structure, small in size, light in weight, and easy to install, use, and maintain. It is suitable for maintenance and loading / unloading work in light to medium-duty machinery workshops, warehouses, material yards, and hydropower stations, and is a lifting equipment widely used in China.

[0003] After a certain period of operation, the steel rail flanges of a crane will show varying degrees of wear and damage. This condition poses a safety hazard to the user and must be replaced when it reaches a certain level. However, replacing the entire rail is costly and requires moving the trolley, which is very complicated. Therefore, overcoming the above-mentioned technical problems and defects has become a key issue that needs to be addressed. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects described in the background art, thereby realizing a conveniently detachable explosion-proof crane travel rail and its usage method. The travel rail is composed of multiple rail sections and is equipped with a mounting base that is easy to install and disassemble, which can save a lot of costs during rail maintenance and eliminates the need to move the trolley.

[0005] To achieve the above-mentioned objectives, the technical solution of this invention is: a conveniently detachable and assembleable explosion-proof crane travel rail, comprising a rail section and a mounting base. The rail section is mounted on a crossbeam via the mounting base. The mounting base includes a base frame and a limiting frame. The lower part of the limiting frame is disposed in a limiting groove in the lower part of the base frame, and a pressure plate is disposed in the upper part of the limiting frame. A pressure rod is disposed in a through groove in the middle of the rail section. The end of the pressure rod is disposed in a pressure groove between the limiting frame and the pressure plate. An adjustment frame that contacts the rail section is disposed in the middle of the pressure rod, and a hydraulic push rod is disposed at the end of the crossbeam.

[0006] Furthermore, the mounting bases are evenly arranged below the track sections, with a trapezoidal protrusion at one end of the track section and a groove corresponding to the trapezoidal protrusion at the other end.

[0007] Furthermore, the inner side of the base frame matches the outer surface of the crossbeam, and the base frame is fixedly connected to the crossbeam by fastening bolts provided on its side wall.

[0008] Furthermore, there are two limiting frames, which are symmetrically arranged on both sides of the base frame. One end of the limiting frame is hinged to the pressure plate, and the other end is fixedly connected by adjusting bolts.

[0009] Furthermore, the adjusting frame includes a roller ring and a pressure roller. The roller ring is rotatably connected to the pressure rod, and the pressure roller is symmetrically installed on the front and rear sides of the roller ring via a connecting axis.

[0010] Furthermore, a pressure rail is fixedly connected to the bottom of the track section at the bottom of the through groove, and the pressure roller is in contact with the pressure rail, and the cross-sectional shape of the pressure roller matches that of the pressure rail.

[0011] A method for using an explosion-proof crane travel rail that is easy to assemble and disassemble includes the following steps:

[0012] 1) Calculate the number of track sections and corresponding mounting bases according to the actual required track length, or calculate the appropriate length of track sections according to the required track length, and remake the track sections according to the calculated track section length.

[0013] 2) Drill holes at the designated locations on the crossbeam and use bolts to fix the mounting bracket to the crossbeam;

[0014] 3) After the pressure rod passes through the through groove, install the adjusting bracket on the pressure rod;

[0015] 4) Place the end of the pressure rod in the pressure groove between the limit frame and the pressure plate, and fix the limit frame and the pressure plate together with bolts to limit the pressure rod.

[0016] The beneficial effects of the easily disassembled and assembled explosion-proof crane travel rail of the present invention and its usage method are as follows:

[0017] The present invention relates to a convenient disassembly and assembly method for an explosion-proof crane travel rail. The rail is divided into multiple rail sections, which are fixed with mounting bases. This facilitates disassembly, replacement, and installation for later maintenance. Only the damaged or severely worn section needs to be replaced, eliminating the need for complete replacement, thus saving maintenance costs and avoiding resource waste. During maintenance, the trolley can be moved to a non-maintenance section, allowing for segmented construction without the need to move the trolley to another location. Compared to traditional maintenance methods, the process is simple, time-saving, and labor-saving, making it extremely convenient. Attached Figure Description
