Problems solved by technology

[0002] In the crane industry, most of the current rails are spliced ​​and welded by processed profiles. In this process, the defect is that the processing process is cumbersome, resulting in waste of processing costs. The most important thing is to enhance its rigidity after splicing. Tight support points must be added during installation

Embodiment Construction

[0010] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the embodiments and accompanying drawings. The embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0011] figure 1 It shows an embodiment of an improved electric hoist track of a crane according to the present invention, the cross section of the track 1 is in the shape of a "U" with the opening downward, and the lower edge carrying the pulley of the electric hoist is arranged on both sides of the opening 2. The lower edge 2 is inclined downward toward the center of the opening and the horizontal plane, the inclination angle is 1-5 degrees, and the end of the lower edge 2 is provided with a protrusion 3, and the protrusion 3 is semicircular shape. The lower edge of the track and the horizontal plane have a very small bevel angle, which can aut...

Abstract

The invention discloses an improved electric hoist track of a crane. The cross section of the track is in a "U" shape with the opening facing downwards. Lower edges for carrying electric hoist pulleys are arranged on both sides of the opening, and the lower edges face toward the center of the opening. and the horizontal plane are inclined downward, and the inclination angle is 1-5 degrees. The track of the present invention replaces the traditional splicing and welding process. This invention technology is direct roll forming. Its rigidity performance is further enhanced. The lower edge of the track has a small bevel angle with the plane, which can realize the automatic correction route function of the gourd trolley in the process of traveling in the track, so that the gourd always walks in the center of the track. In the process of use, a large-span connection point can also be realized. Compared with the traditional track, the technology of the present invention integrates the market demand to achieve a large-span, easy installation, high-load working process and low-cost processing process.

Description

technical field [0001] The invention relates to the field of crane equipment, in particular to an improved electric hoist track of a crane. Background technique [0002] In the crane industry, most of the current rails are spliced ​​and welded by processed profiles. In this process, the defect is that the processing process is cumbersome, resulting in waste of processing costs. The most important thing is to enhance its rigidity after splicing. Tight support points must be added during installation. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides an improved crane electric hoist track which is light, high-load and easy to install. [0004] The technical solution adopted by the present invention in order to solve the technical problem is: an improved crane electric hoist track, the cross section of the track is a "U" shape with the opening downward, and the two sides of the opening are provided with pull...
