Description

Technical Field

[0001] The utility model relates to the field of railway engineering, in particular to a rail fixing and reinforcing device for railway line maintenance. Background Art

[0002] Railways are track lines for trains and other vehicles to travel on, and steel rails are a type of railway facility used on railways. They work with switches and turnouts to enable trains to travel without turning. Steel rails are usually welded to a steel base for use.

[0003] At present, after long-term use, the rails and the connecting parts will become loose or broken. Workers need to carry out regular maintenance to ensure the normal operation of the railway. Most of the maintenance is to limit and fix the extra parts on both sides of the lower part of the rails, but the middle part is not fixed, and the fixing range is small. Under the strong dynamic load of the train, the impact stress of the rails will increase, forming stress concentration, which can easily cause the middle part of the rails to break again, thereby causing a derailment accident.

[0004] In summary, there is an urgent need for a rail fixing and reinforcing device for railway line maintenance that can fix the middle part of the rail to solve the above problems. Utility Model Content

[0005] In order to overcome the disadvantage that only the extra parts on both sides of the lower part of the rail are fixed, which easily leads to the breakage of the middle part of the rail, the purpose of the utility model is to provide a rail fixing and reinforcement device for railway line maintenance that can fix the middle part of the rail.

[0006] The technical solution is as follows:

[0007] A rail fixing and reinforcement device for railway line maintenance comprises a steel base, a rail plate, a bonding plate, a protrusion, a connecting frame, a fixing piece, a stabilizing frame, a fastener, a limit frame and a stabilizer. Two rail plates are connected between the tops of the two steel bases. The rail plates are symmetrically arranged front and back and are in an inverted T shape. Bonding plates are connected to the front and back sides of the rail plates. Protrusions are slidably arranged on the bonding plates. A connecting frame is connected to the protrusions. A fixing piece is fixedly connected to the lower part of the connecting frame. The fixing piece is threadedly connected to the steel base. Two stabilizing frames form a group. A group of stabilizing frames are clamped on both sides of the lower part of the rail plates. The bottom of each group of stabilizing frames is connected by fasteners. The outer side of each group of stabilizing frames is connected to a limiting frame. The limiting frame is fixedly connected to a stabilizer.

[0008] As an improvement of the above scheme, it also includes a clamping plate, a connecting plate and a screw rod. The outer sides of two adjacent bonding plates are symmetrically slidably connected with a clamping plate, and at least two connecting plates are slidably connected to each bonding plate. The connecting plates are connected with screw rods, and the screw rods are in the same plane as the bottom of the stabilizer.

[0009] As an improvement of the above solution, a fixing frame is also included, the upper part of the screw rod is connected with the fixing frame, and the fixing frame is threadedly connected to the adjacent steel base.

[0010] As an improvement of the above solution, a damping block is further included. The damping blocks are connected to both sides of the interior of the fixing frame, and the damping blocks are in contact with and fit with the adjacent screw rods.

[0011] As an improvement of the above solution, it also includes a limiting plate, and the limiting plates are connected to the left and right sides of the bonding plate. The limiting plates are arranged in an L shape and abut against the protrusion.

[0012] As an improvement of the above solution, the lower part of the stabilizer is conical.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. The utility model fixes the middle part of the rail plate by welding the bonding plate to the front and rear sides of the rail plate, installing the protrusions on both sides of the bonding plate, and threadedly fixing them on the steel base, thereby achieving the purpose of reinforcement and reducing the risk of the rail plate breaking again.

[0015] 2. The utility model can further fix the plate by installing the clamping plate on both sides of the bonding plate, installing the connecting plate on the clamping plate with screws, installing the screw rod on the connecting plate, and finally inserting the screw rod into the ground.

[0016] 3. The utility model can fix the screw rod by installing the fixing frame on the screw rod and rotating the fixing frame to fix it on the steel base. BRIEF DESCRIPTION OF THE DRAWINGS

Two stabilizing frames 7 form a group. A group of stabilizing frames 7 are clamped on both sides of the lower part of the rail plate 2. The bottom of each group of stabilizing frames 7 is connected by a fastener 8. The fastener 8 includes a bidirectional screw that passes through the lower part of each group of stabilizing frames 7, and a fastener that is threadedly connected to both ends of the bidirectional screw. Nuts, when the fastening nuts are screwed toward the middle, the stabilizing frames 7 on both sides can be pressed against the rail plate 2, and the outer sides of the two adjacent stabilizing frames 7 are connected to the limiting frames 9, and the limiting frames 9 are welded with stabilizers 10, and the lower part of the stabilizer 10 is conical. The stabilizer 10 is inserted into the ground to fix the rail plate 2, and the left and right sides of the bonding plate 3 are connected to the limiting plates 11, which are L-shaped and abut against the protrusion 4, and the outer sides of the two adjacent bonding plates 3 are symmetrically connected with the clamping plates 1 2.
