Description

Technical Field

[0001] The utility model relates to the technical field of track torsion processing devices, in particular to a steel track torsion processing device. Background Technique

[0002] The steel rail is the main component of the railway track. Its function is to guide the wheels of locomotives and vehicles to move forward, bear the huge pressure of the wheels, and transmit it to the sleeper. The steel rail must provide a continuous, smooth and least resistant rolling surface for the wheels. In electrified railways or automatic block sections, the steel rail can also be used as a track circuit. In China, the steel rails can be divided into three types according to the weight per meter in kilograms: crane rails, heavy rails and light rails. Crane rails are divided into four types: QU120, QU100, QU80, and QU70. The material is generally manganese steel, and the heaviest single weight is QU120, which can reach 118 kg / m. Heavy rails are divided into ordinary manganese-containing steel rails, copper-containing plain carbon steel rails, high-silicon copper-containing steel rails, copper rails, manganese rails, silicon rails, etc. There are mainly three types: 38, 43, and 50 kg.

[0003] For example, a steel track switch torsion processing device with the publication number of CN102527793A includes a first unit body and a second unit body. The first unit body and the second unit body are fixedly connected into one body through an intermediate connecting plate. The first unit body and the second unit body respectively include two spaced substrates, and the substrates are arranged parallel to each other. Symmetric mounting blocks are installed between the two substrates of the first unit body. A fixture sliding channel and a pin hole are opened in the mounting block. A fixture is installed in the fixture sliding channel. One ends of the left and right fixtures are respectively fixedly connected to the piston rods of the clamping cylinders. A locking mechanism is installed at the bottom of the mounting block. The locking mechanism includes a locking cylinder, a locking pin and a mounting plate. One end of the locking cylinder is fixedly connected to the bottom of the mounting block, and the piston rod at the other end of the locking cylinder is connected to the mounting plate.

[0004] The above device meets the processing and manufacturing of various different types of steel rails through the combination of multiple components such as unit bodies, reduces the cost of mold design and mold manufacturing, and can detect the extension stroke of the oil cylinder through a sensor and calculate the size of the torsion angle. However, due to the size of its shape, the above device often needs to be torsionally processed multiple times to torsionally process a section of steel rail completely, which takes a lot of time and results in low efficiency. Content of the Utility Model

[0006] To achieve the above object, the present utility model provides the following technical solutions: A steel rail torsion processing device includes a moving end face, a moving rail frame is arranged at the upper end of the moving end face, and fixing frames are arranged on both sides of the moving rail frame. At the same time, a torsion device is arranged in the center of the moving end face. An active layer is arranged in the middle of the moving rail frame, and moving bolts are arranged corresponding to the fixing frames on the active layer. At the same time, fixing ends are arranged on the outer surface of the fixing frames corresponding to the positions of the moving bolts. A control end is arranged at the upper end of the fixing frame, and a driving device is arranged at the upper end of the torsion device.

[0007] Preferably, the lower end of the driving device is connected to a starting device, and a downward pressure support arm is arranged at the lower end of the starting device. At the same time, a downward pressure torsion end is arranged at the lower end of the downward pressure support arm.

[0008] Preferably, a concave opening that meshes with the side surface of the steel rail is arranged at the bottom of the downward pressure torsion end.

[0009] Preferably, a fitting column is arranged inside the fixing frame, a rotating column is connected to the outside of the fitting column, and an external adjustment end is connected to the rotating column.

[0010] Preferably, a meshing column is arranged in the center of the fitting column, rotating gaskets are arranged at the upper and lower ends of the fitting column, and the rotating gaskets are connected to the upper control end.

[0011] Preferably, a follow-up meshing plate is arranged in the middle section of the rotating gasket.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] 1. Compared with other steel rail torsion processing devices, this device twists the steel rail through the fixing frame arranged on the moving end face and the torsion device arranged in the center. Since the bottom of the fixing end is stabilized by a stop bolt, it can be replaced in position on the moving end face, so that the fixing end can twist and process steel rails of different lengths as needed.

[0014] 2. In addition, the device is provided with adjustment ends inside the fixing frames. When the angle of the steel rail changes due to the downward pressure of the torsion device, the adjustment ends arranged on the sides of the two fixing frames will appropriately adjust the angle of the steel rail itself, preventing the middle section of the steel rail from twisting during the bending and torsion process while the two sides are fixed by the fixing frames, resulting in the phenomenon that the steel rail breaks due to relative force.

Specific implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 3 , the present invention provides a technical solution:

[0021] Figure 1 This is the front overall view of the device. The main body is the moving end face 1. The upper end of the moving end face 1 is provided with a moving rail frame 2, and fixed frames 3 are arranged on both sides of the moving rail frame 2. The arrangement of the moving rail frame 2 enables the fixed frame 3 to move freely on the moving end face 1, that is, it can adjust the twisting distance according to the length of the steel rail. At the same time, a twisting device is arranged in the center of the moving end face 1. An active layer is arranged in the middle of the moving rail frame 2, and a moving bolt is arranged corresponding to the fixed frame 3 on the active layer. At the same time, a fixed end 6 is arranged on the outer surface of the fixed frame 3 corresponding to the position of the moving bolt. When the fixed frame 3 is placed on the moving end face 1 and moves to the required position, the moving bolt is fixed in position by arranging fixed ends 6 at both ends, so as to achieve the effect of stabilizing and fixing the base of the fixed frame 3. The upper end of the fixed frame 3 is provided with a control end 4, and a driving device 5 is arranged at the upper end of the twisting device;

[0022] Figure 2 This is the internal view of the twisting device of the device. The main body is the driving device 5. The lower end of the driving device 5 is connected to the starting device 9, and a downward pressing support arm 10 is arranged at the lower end of the starting device 9. At the same time, a downward pressing and twisting end 8 is arranged at the lower end of the downward pressing support arm 10. A recess for meshing with the side surface of the steel rail is arranged at the bottom of the downward pressing and twisting end 8. The driving device 5 transmits kinetic energy to the starting device 9 to make it start to operate, moves the downward pressing support arm 10 downward, and meshes and presses and twists the embedded part of the steel rail with the front downward pressing and twisting end 8. And the angle of the downward pressing and twisting end 8 here is set in a bent shape so that the diffusion surface of the acting force can be kept wide and the force is evenly distributed when pressing and twisting downward;

[0023] Figure 3The figure is an internal view of the fixing frame 3 of the device. The main body is the fixing frame 3. The fixing frame 3 has a fitting column 12 disposed inside. The outer side of the fitting column 12 is connected to the rotating column 13. The rotating column 13 is connected to the external adjustment terminal 14. The arrangement of the outer terminal makes the device itself have rotational inertia, and a larger force is required to rotate it, so as to prevent the fitting column 12 from rotating when it is not pressed down and twisted, resulting in positional deviation and other errors. By adjusting the arrangement of the terminal 14, the change in the angle of the middle rail of the device when it is pressed down and twisted can be transmitted to the meshing columns 15 on both sides, and the fitting column 12 can be rotated to offset the change, so as to prevent The impact of force causes the rail to break. An engaging column 15 is arranged in the center of the fitting column 12, and a rotating gasket 11 is arranged at the upper and lower ends of the fitting column 12. At the same time, the rotating gasket 11 is connected to the upper control end 4, and a follower engaging plate is arranged in the middle section of the rotating gasket 11. The placement of the rotating gasket 11 and the follower engaging plate is mainly controlled by the upper control end 4. When the control end 4 feels the action of force, it will control the lower end connecting device to move in the same direction as the force according to the direction of the force offset. On the one hand, it can reduce the torque between the device and the fixed frame 3 when it rotates to avoid damage to the fixed frame 3. On the other hand, it can have a buffering and stabilizing effect when the angle changes.

[0024] In actual use, first, the rail is placed inside through the internal meshing lines of the meshing column 15 according to the effective torsion length of the rail, and then the meshing column 15 is placed along the inside of the bonding column 12. The follow-up meshing plate is pressed against the meshing column 15 through the control end 4, and the downward twisting of the rail can be started. The driving device 5 drives the starting device 9 to press down the pressing arm 10, and then the pressing and twisting end 8 is used to effectively press down the rail. As the downward pressure is carried out, the follow-up meshing plates and rotating patches arranged on the fixed frames 3 on both sides follow and rotate until the operation is completed.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
