Problems solved by technology

[0002] At present, the sleepers used for mine track laying mainly use concrete sleepers and wooden sleepers. On the one hand, there are short service life, complicated laying and installation, high maintenance cost and ecological damage, and are not environmentally friendly; on the other hand, traditional Sleepers are large in size and heavy in weight, inconvenient for transportation and storage, and cannot be recycled after being scrapped

Embodiment

[0014] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, a flexible combined steel sleeper, the sleeper 2 is stuck on the slot-shaped backing plate 1, and the sleeper 2 is fixed on the slot-shaped backing plate 1 by fastening bolts 3 to form a whole sleeper; on the sleeper 2 A fixed bayonet 4 for the gauge is provided, and the sleeper 2 is formed by pressing a steel plate with a trapezoidal cross section.

[0015] Fix the groove-shaped backing plate 1 on the flat concrete ground first, then install the sleeper 2 into the groove-shaped backing plate 1, fasten the bolts 3 to fix the sleeper 2 on the groove-shaped backing plate 1, so as to realize the connection between the sleeper 2 and the groove-shaped backing plate 1. The amount of elastic deformation between the slot-shaped backing plates 1 is adjusted; the sleeper 2 is molded by a whole piece of steel plate at one time, and its structural shape and size are standard, and the structural bearing capacity is str...

Abstract

The invention discloses a flexible combined steel sleeper. A sleeper body is clamped in a clamping-groove-shaped base plate, and the sleeper body is fixed to the clamping-groove-shaped base plate through fastening bolts. The flexible combined steel sleeper has the advantages that the sleeper body is of a trapezoidal steel structure which can generate micro deformation; due to the fact that a good angle and a good thickness are designed for the sleeper body, the purpose that the sleeper body cannot generate irreversible plastic deformation when bearing static pressure or dynamic load impact is achieved, the flexibility effect is achieved, and operating devices walking or working on a rail are protected; due to the fact that the flexible combined steel sleeper is made of a steel plate in a pressing forming mode, the structural dimensions are standard, interchangeability is good, assemblies which can be freely combined are produced with the smallest number of dies and the lowest die cost, the production cost is well controlled, and an excellent basis of price is provided for the later period.

Description

technical field [0001] The invention relates to a flexible steel track sleeper used for laying mine tracks. Background technique [0002] At present, the sleepers used for mine track laying mainly use concrete sleepers and wooden sleepers. On the one hand, there are short service life, complicated laying and installation, high maintenance cost and ecological damage, and are not environmentally friendly; on the other hand, traditional Sleepers are large in size and heavy in weight, inconvenient for transportation and storage, and cannot be recycled after being scrapped. Contents of the invention [0003] The object of the present invention is to provide a flexible steel sleeper for mine track laying. [0004] The technical solution of the present invention is: a flexible combined steel sleeper, the sleeper is stuck on the groove-shaped backing plate, and the sleeper is fixed on the groove-shaped backing plate by fastening bolts. [0005] There is a track gauge fixing bayo...
