In order to replace the existing solid guide rail, reduce the specific gravity of unit volume, logistics transportation cost and vertical installation and maintenance cost, the hollow guide rail is closed, and reinforcing ribs are added in the filling of the composite material, so that the problems of structural rigidity and strength are solved, and the solid guide rail is replaced. Meanwhile, the existing solid guide rail is used as a coupling piece of a braking component, rust-preventive oil is coated on the surface of the guide rail when the guide rail leaves a factory, and when the guide rail is installed on a construction site, due to the sensitivity of the safety braking component to the rust-preventive oil, the rust-preventive oil needs to be removed, and then lubricating oil is coated, so that the safety braking is seriously affected due to improper field treatment of the construction site, and meanwhile, the environment pollution and the subsequent maintenance cost are increased due to the lubricating oil.
Therefore, how to essentially replace a solid guide rail by a closed hollow guide rail structure and adding reinforcing ribs in a filling material, thereby reducing the weight of the guide rail, lowering the cost and improving the guiding performance of the guide rail is a problem to be solved in the current guiding and braking fields.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
Example 1
As shown in fig. 1, the guide rail of the present embodiment includes an active surface 100, a transition surface 200, and a mounting surface 300, where the active surfaces 100 on two sides transition to the mounting surface 300 through the transition surfaces 200 on the same side respectively; the action surface 100, the transition surface 200 and the mounting surface 300 form a cavity, and the cavity is filled with a composite material, and the composite material is internally provided with a metal reinforcing rib 400.
The composite material is filled in the guide rail, and one or more metal reinforcing ribs are arranged in the cavity, so that the guide rail disclosed by the invention has the effect of being completely equivalent to and exceeding that of a solid guide rail, has higher bearing capacity and lighter weight, and can be used for realizing braking of a safety tongs. The guide rail of the present invention may be used in place of two solid guide rails, T75 and T89, with different metal plate structures selected to form the guide rail of the present invention instead of different solid guide rails.
Compared with a solid guide rail, the guide rail provided by the invention has a thinner wall thickness of only 1.5mm, the weight of the traditional solid guide rail is 7.8g/cm 3, and the weight of the guide rail provided by the invention is 2.0-2.1g/cm 3.
In this embodiment, the composite material is an elastic, compressive, and bending resistant composite material, and includes one or more combinations of cement and engineering plastics, carbon fibers, mineral fillers, and metal fibers (filaments), etc. Compared with solid steel, the composite material can achieve higher bearing capacity and lower weight.
As shown in fig. 2, the active surface 100 of the guide rail includes a first active surface 110, a second active surface 120, and a third active surface 130, and the second active surface 120 is disposed between the first active surface 110 and the third active surface 130. The metal reinforcing ribs 400 extend from the mounting surface 300 toward the second active surface 120 to increase the bearing capacity of the rail. The number and size of the metal reinforcing bars 400 are determined by the specific working conditions and can be designed and adjusted according to the requirements.
Example 2
As shown in fig. 3 and 4, the guide rail provided in this embodiment is formed by integrally forming a metal plate into a working surface 100, a transition surface 200, a mounting surface 300 and a metal reinforcing rib 400, where the working surface 100 transitions to the mounting surface 300 through the transition surface 200; the metal plate is welded to the mounting surface 300. The active surface 100, the transition surface 200 and the mounting surface 300 form a cavity; the active surface 100 of the guide rail comprises a first active surface 110, a second active surface 120 and a third active surface 130, the second active surface 120 being arranged between the first active surface 110 and the third active surface 130.
The metal plate of the mounting surface 300 is divided into a first mounting plate 310 and a second mounting plate 320, and the second mounting plate 320 and the metal reinforcing rib 400 are in arc transition, and the arc transition is welded at the end surface of the first mounting plate 310.
The guide rail in this embodiment is integrally formed by a metal plate, and the terminal end (the second mounting plate 320) of the metal plate extends towards the second acting surface 120 to form the metal reinforcing rib 400, which is convenient for processing and can ensure the strength of the guide rail.
In order to ensure accurate positioning of the guide rail on the mounting surface, when the first mounting plate 310 and the second mounting plate 320 are welded, the welding surface cannot be higher than the mounting surface 300 of the guide rail, so that the guide rail forms a closed cavity in the welding direction, and the strength of the guide rail in the welding direction is increased. Preferably, the first mounting plate 310 and the metal reinforcing rib 400 are in arc transition, and the arc transition is welded on the end face of the first mounting plate. The first mounting plate 310 and the metal reinforcing ribs 400 are welded through arc transition, so that the guide rail forms a closed cavity, and the composite material is convenient to directly fill. Compared with the welding area without the welding area, the welding method is simpler and more convenient and efficient, and meanwhile, the subsequent processing is avoided from being increased because the welding seam is higher than the third plane.
As shown in fig. 5, the first mounting plate 310 forms an arc bend at the welding position, and the second mounting plate 320 is welded to the bend, so as to further increase the strength of the guide rail in this direction. Simultaneously, two circular arcs form a welding area, so that the welding is convenient, and meanwhile, the welded seam after the welding can meet the requirement lower than the mounting surface 300, and the subsequent processing procedure of welding the welded seam surface is reduced.
The shape of the metal reinforcing rib 400 in this embodiment may be determined according to specific working conditions, such as any one of fig. 3 to 5, and may also be other structural forms. Preferably, the metal reinforcing rib 400 is extended to the top of the acting surface, or is made into a curved shape, and at least one curved inflection point of the reinforcing rib 400 contacts with the inner wall of the acting surface to meet the bearing requirements under different working conditions.
In order to further achieve the effects of green, environmental protection, energy conservation and the like, the action surface of the guide rail is subjected to laser electroplating treatment so as to avoid pollution and potential safety hazard caused by coating rust preventive oil on the guide rail when the guide rail leaves a factory.
To further reduce the noise of the guide rail, a sound absorbing material is added to the composite material to absorb part of the noise.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention; thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
