Description

Technical Field

[0001] This utility model relates to the field of track welding point repair technology, and more specifically, to a track welding point repair and reinforcement device. Background Technology

[0002] With the acceleration of global urbanization and the increasing frequency of economic exchanges between regions, rail transit, with its significant advantages such as large capacity, high efficiency, low energy consumption, and environmental friendliness, has become a key component of the modern transportation system. Whether it's subways and light rail in urban rail transit, or high-speed and conventional railways in the national railway network, they are all constantly expanding in scale and improving in operating speed and service quality. Rails are typically composed of multiple steel rails connected by welding. The welding points are critical parts of the track structure; the quality of the welding directly affects the overall strength, stability, and durability of the track. Under ideal welding conditions, the welding points should possess mechanical properties similar to the base material, capable of withstanding the enormous dynamic loads, impact loads, and thermal stresses caused by temperature changes generated during train operation.

[0003] However, in the actual rail welding process, due to the influence of various factors, some defects and problems inevitably occur at the weld points. For example, improper control of welding process parameters may lead to defects such as porosity, slag inclusion, and lack of fusion inside the weld; welding environmental factors such as humidity, temperature, and wind speed may cause welding cracks if they do not meet the requirements; in addition, during long-term use, the rail is subjected to repeated action of train wheel-rail forces, uneven settlement of the rail foundation, and erosion by the natural environment, which can easily cause fatigue damage, wear, and corrosion at the weld points, resulting in a decrease in the strength and stability of the weld points.

[0004] A search revealed that patent application number CN202210999013.9 discloses a portable rail damage welding and repair device. This device, relying on the cooperation of a first and second traveling component, can move along the damaged rail line. The welding and repair component completes the welding repair of the rail damage. A welding adjustment mechanism adjusts the angle of the welding head to align it with the damaged area for welding and repair. This avoids the time-consuming, labor-intensive, and safety issues associated with manual welding, thus improving the efficiency and reliability of rail damage welding and repair.

[0005] For defects and damage at rail welding points, common repair and reinforcement methods mainly include manual welding repair and mechanical reinforcement. The portable rail damage welding repair equipment designed in the above patent uses the method of controlling the lifting and rotation of the welding head to weld and repair the rail. The drawback of this method is that each welding can only be performed on a single rail, and it cannot weld and repair two rails at the same time. For broken or top-view rail sections, welding only on the surface is not reliable. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, this utility model provides a track welding point repair and reinforcement device.

[0008] As a further improvement to the technical solution of this utility model, the bottom of the fixing frame and the top of the support base are fixedly connected by bolts, and a distribution box is fixedly installed on the top of the support base on one side of the fixing frame, and a control switch is provided on the outer wall of the distribution box.

[0009] As a further improvement to the technical solution of this utility model, the support base is provided with a through hole for the discharge pipe to pass through, and the drive motor is fixedly connected to the outer wall of the end of the fixed shell by screws.

[0010] As a further improvement to the technical solution of this utility model, the adjustment mechanism includes a fixed plate fixedly connected to the inner sidewalls of both ends of the first side plate, a first screw connected between the two fixed plates, and a first servo motor for driving the first screw to rotate is fixedly installed on the outer wall of one of the fixed plates. A first movable seat is connected to the outside of the first screw. The adjustment mechanism also includes a second movable seat connected to the inner sidewall of the second side plate corresponding to the position of the first movable seat. A second screw is connected between the first movable seat and the second movable seat in the horizontal direction. A second servo motor for driving the second screw to rotate is installed inside the second movable seat, and a movable block is connected to the outside of the second screw. A mounting plate is fixedly connected to the front end of the movable block. A telescopic cylinder is fixedly installed on the outer wall of the mounting plate. A lifting plate is fixedly connected vertically downward at the output end of the telescopic cylinder. The welding torch is installed at the bottom of the lifting plate. A limiting ring for fixing the position of the repair paste outlet is connected to the outer wall of the lifting plate. The bottom of the repair paste outlet is located near the side where the welding torch is located.

[0011] As a further improvement to the technical solution of this utility model, the outer wall of the first movable seat is provided with a first T-shaped slider connected to the inner wall of the first side plate, and the inner wall of the first side plate is provided with a first T-shaped groove in the horizontal direction corresponding to the outer side of the first T-shaped slider.

[0012] As a further improvement to the technical solution of this utility model, the end of the second movable seat is provided with a second T-shaped slider connected to the inner side wall of the second side plate, and the inner side wall of the second side plate is provided with a second T-shaped groove in the horizontal direction corresponding to the outer side of the second T-shaped slider.

[0013] As a further improvement to the technical solution of this utility model, the movable block is provided with a screw hole matching the external thread structure of the second screw, and a limiting rod is fixedly connected between the first movable seat and the second movable seat through the top of the movable block in the horizontal direction, and a limiting hole is provided inside the movable block corresponding to the outside of the limiting rod.

[0014] The beneficial effects of this utility model are: 1. By setting an adjustment mechanism, the first servo motor drives the first screw to rotate. The first movable seat is limited by the T-shaped slider / groove to maintain displacement in the horizontal Y-axis direction, thereby driving the second movable seat and the second screw to move in the Y-axis direction. This causes the movable block connected to the second screw, as well as the welding gun and repair paste outlet head, to move in the Y-axis direction. At the same time, by controlling the second servo motor to drive the second screw to rotate, the movable block is limited by the limit rod to maintain stable movement in the horizontal X-axis direction, thereby driving the welding gun and repair paste outlet head to move in the X-axis direction. The piston rod of the telescopic cylinder can be extended and retracted to easily control the vertical Z-axis displacement of the welding gun and repair paste outlet head. This allows for convenient control of the welding position of the track as needed during use, achieving welding reinforcement of the track welding point. It enables simultaneous dual-track welding operations, allowing operators to stand and observe without squatting or bending over, reducing labor intensity. 2. By setting up a metal repair paste tank, during use, opening the solenoid valve and starting the drive motor will rotate the spiral extrusion auger. This allows the metal repair paste flowing out of the tank under gravity to enter the discharge pipe through spiral extrusion. The discharge pipe is connected to the repair paste outlet by a flexible hose. The length of the hose can be set as needed to accommodate movement in the X, Y, and Z axes during use. This facilitates the extruded metal repair paste flowing into the track to be repaired, allowing the metal repair paste to penetrate into the broken track steel. Combined with a welding torch, this achieves the repair and reinforcement of the track welding points. Attached Figure Description

[0026] Working principle: This utility model designs a device for repairing and reinforcing rail welding points. The specific structure is shown in the attached instruction manual. Figure 1-5 As shown, in use, the wheels 4 on both sides of the bottom of the device are placed on both sides of the track, so that the position to be welded and repaired is placed at the bottom of the device. At this time, through the set adjustment mechanism, the first servo motor 17 drives the first screw 16 to rotate. The first movable seat 18 is limited by the T-shaped slider / groove to maintain displacement in the horizontal Y-axis direction, thereby driving the second movable seat 21 and the second screw 22 to move in the Y-axis direction, and causing the movable block 24 connected to the second screw 22, as well as the welding gun 28 and the repair paste outlet 30, to move in the Y-axis direction.

The vertical Z-axis displacement of the repair paste outlet 30 and the 8-section allows for convenient control of the welding position on the track during use, enabling welding reinforcement of the track welding points. Simultaneously, the metal repair paste tank 6, when used, allows the solenoid valve 9 to be opened and the drive motor 11 to rotate the screw extruder 10. This causes the metal repair paste flowing from the tank 6 under gravity to be extruded into the discharge pipe 12 via a screw extrusion. The discharge pipe 12 is connected to the repair paste outlet 30 by a flexible hose 31. The length of the hose 31 can be adjusted as needed to accommodate movement in the X, Y, and Z axes, facilitating the flow of the extruded metal repair paste into the track to be repaired. This, combined with the welding torch 28, repairs and reinforces the track welding points. After repairing one location, the device can be moved to the next repair location as needed.
