Description

Technical Field

[0001] The utility model relates to the technical field of railway construction, in particular to a low-disturbance reinforcement construction device for heavy-haul lines. Background Technique

[0002] Heavy-haul railway transportation has been widely emphasized by railways around the world due to its large transportation capacity, high efficiency, and low transportation cost. Especially in some countries with vast territories, rich resources, and a large proportion of bulk cargo transportation such as coal and ore, it has developed particularly rapidly. At present, heavy-haul transportation has been internationally recognized as the direction of railway freight development and has become an important trend in the development of the world's railways.

[0003] The Shuohuang Railway Line is a heavy-haul railway with relatively high construction difficulty. To ensure the safety of railway operation and construction, it is necessary to reinforce the railway line. However, the effect of the ordinary reinforcement scheme of adding I-beams is average, and it is not convenient to replace in case of cracks in a certain section in the future, which brings inconvenience to the overall maintenance in the future.

[0004] Therefore, it is particularly important to design a low-disturbance reinforcement construction device for heavy-haul lines to change the above technical defects and improve the overall practicability. Content of the Utility Model

[0005] The purpose of the utility model is to provide a low-disturbance reinforcement construction device for heavy-haul lines to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical scheme:

[0007] A low-disturbance reinforcement construction device for heavy-haul lines includes two groups of rails symmetrically distributed left and right. A plurality of sleepers with the same interval are fixed between the two groups of rails. A track reinforcement structure is arranged between the two groups of rails and at the bottom of the sleepers.

[0008] The described track reinforcement structure includes multiple groups of longitudinally arranged reinforcement girders that are evenly arranged horizontally. On the left and right sides of the tops of multiple groups of the reinforcement girders, connecting ear plates are jointly connected. At the left and right ends of the top of each group of the reinforcement girders, limit sockets are fixed. Inside each group of the limit sockets, reinforcement taper rods are inserted. On the front and back sides of each group of the reinforcement girders, connecting slots are symmetrically opened left and right. Between every two adjacent groups of the reinforcement girders, cross-beam sleeves are symmetrically arranged left and right. On the left and right sides of each group of the cross-beam sleeves, waist-shaped sliding grooves are symmetrically opened front and back. Inside each group of the cross-beam sleeves, reinforcement cross-beams are symmetrically slidably connected front and back. On the left and right sides of each group of the reinforcement cross-beams, guide buckles that are slidably matched with the waist-shaped sliding grooves are arranged. On the opposite sides of the two groups of the reinforcement cross-beams at the same position, connecting plug blocks are arranged. At the front end of the reinforcement cross-beam located at the rear side, a telescopic outer rod is fixed. At the rear end of the reinforcement cross-beam located at the front side, a telescopic inner rod that is slidably connected with the telescopic outer rod is fixed. Inside the telescopic inner rod, fixing card holes are evenly opened. At the top of the telescopic outer rod, a fixing plug rod that is clamped and matched with the fixing card holes is movably inserted.

[0009] As a preferred solution of the present utility model, each group of the connecting ear plates is fixedly connected to the rail and the reinforcement girder through bolts.

[0010] As a preferred solution of the present utility model, through hole grooves for the reinforcement taper rods to pass through are opened at the left and right ends inside each group of the reinforcement girders and at positions corresponding to the limit sockets.

[0011] As a preferred solution of the present utility model, the connection method between the reinforcement taper rod and the limit socket is a sliding connection.

[0012] As a preferred solution of the present utility model, the external structure size of the reinforcement cross-beam is adapted to the internal structure size of the cross-beam sleeve.

[0013] As a preferred solution of the present utility model, the connection method between the connecting slot and the connecting plug block at the same position is a plug-in connection.

[0014] As a preferred solution of the present utility model, the bottom end of the fixing plug rod penetrates through the telescopic inner rod and extends to the bottom of the telescopic outer rod and is threadedly connected with a locking nut.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] In the present utility model, a low-disturbance reinforcement construction device for heavy-load lines is provided. After comparative analysis, the reinforcement structure uses a crossbeam system for line reinforcement. Reinforcement longitudinal beams are evenly connected between two groups of steel rails through connecting ear plates, and reinforcement cone rods are added at both ends of the reinforcement longitudinal beams to enhance the connection force with the ground, making the grip at both ends of the reinforcement longitudinal beams stronger. Then, adjustable reinforcement crossbeams are symmetrically arranged on the left and right between every two adjacent reinforcement longitudinal beams. By sliding the front and rear two groups of reinforcement crossbeams inside the crossbeam socket, the connecting plug can be inserted into the corresponding connecting slot for fixed connection of the crossbeam and longitudinal beam. Then, the telescopic outer rod and the telescopic inner rod are fixed by inserting the fixed plug rod into the corresponding fixed card hole, completing the sequential fixation of the reinforcement crossbeams. This not only has a fast installation efficiency but also is convenient for replacement when a certain part is damaged, ultimately realizing the effective connection between the railway and the highway network.
