Description

Technical Field

[0001] This utility model relates to the field of track engineering equipment technology, and in particular to a pin-pulling device suitable for turnout slide plates. Background Technology

[0002] To adapt to the rapid development of urban rail transit projects, the number of track lines and various types of turnouts laid is increasing year by year. Turnout maintenance has become an important part of track engineering construction, and removing the slide plate pins is one of the operations involved in turnout maintenance. Before installation, the turnout slide plate pins are already installed in the side holes that match the slide plates. During construction, the common method of dismantling them is to repeatedly and forcefully strike them with a hammer. This not only easily damages the finished product but also poses certain safety hazards. The process of removing the pins is particularly dependent on the operator's experience and is inconvenient. Furthermore, after the track has been in operation for a period of time, the slide plate pins often rotate to a certain angle. Most existing pin removal tools are of a fixed structure and cannot be adjusted according to the position of the slide plate pins, making them unsuitable for maintenance. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pin-pulling device suitable for turnout slide plates, which can simplify the pin-pulling process of turnout slide plates and adjust the angle of pin-pulling.

[0004] The purpose of this utility model is achieved through the following technical solution: a pin-removing device suitable for turnout slide plates, comprising a support frame, an actuating rod mounted on the support frame and capable of lifting and lowering, and a clamping plate rotatably mounted on the end of the actuating rod. The actuating rod is a double-ended threaded rod, with a force-applying part at one end and a positioning part at the other end. The clamping plate is a double-ended clamping plate, with a first limiting groove at one end for limiting the pin and a second limiting groove at the other end for limiting the positioning part. The first limiting groove is a through groove and the first limiting groove and the second limiting groove are interconnected.

[0005] The force-applying part is also equipped with a rotating rod, which drives the actuating rod to perform reciprocating lifting and lowering movements. The first and second limiting grooves both have T-shaped cross-sections, and their wide ends are interconnected. The width of the narrow end of the first limiting groove is greater than the diameter of the actuating rod, facilitating the installation and removal of the actuating rod. The support frame consists of a support plate and legs fixed to the support plate. The support plate has threaded holes for the actuating rod to pass through. The stroke of the actuating rod is greater than the height of the legs.

[0006] Before use, the support frame, actuating rod, and clamping plate are assembled. The flat-head side of the turnout slide plate pin is placed in the first limiting groove of the clamping plate. Rotating the actuating rod moves it upward, causing the clamping plate to move. At this time, the clamping plate moves the pin outward simultaneously, finally pulling out the pin. It should be noted that the clamping plate and actuating rod are rotated and installed by the positioning part and the second limiting groove. Since the height of the turnout slide plate pin is pre-installed, some pins will rotate after running on the track for a period of time. This application can use the clamping plate to rotate and place the flat-head side of the turnout slide plate pin in the first limiting groove of the clamping plate to accommodate pins in different positions. At the same time, since the first limiting groove and the second limiting groove are connected, the actuating rod can be installed through the first limiting groove, which is convenient for operation.

[0007] The beneficial effects of this utility model are as follows: by rotating and installing a double-headed clamping plate on the double-headed actuating rod, the rotating clamping plate can be used for turnout slide plate pins at different positions and angles. At the same time, the first limiting groove and the second limiting groove are connected to each other, and the actuating rod can be installed through the first limiting groove, which facilitates the installation of the actuating rod, makes the structure of the entire device more reasonable, simplifies the process of removing the pins from the turnout slide plate, and realizes the adjustment of the angle of removing the pins.

[0013] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] like Figures 1-3As shown, a pin-removing device suitable for turnout slide plates includes a support frame 1, an actuating rod 2 mounted on the support frame 1 and capable of lifting and lowering, and a clamping plate 3 rotatably mounted on the end of the actuating rod 2. The actuating rod 2 is a double-ended threaded rod, with a force-applying part 201 at one end and a positioning part 202 at the other end. The clamping plate 3 is a double-ended clamping plate, with a first limiting groove 301 for limiting the pin 4 at one end and a second limiting groove 302 for limiting the positioning part 202 at the other end. The first limiting groove 301 is a through groove and the first limiting groove 301 and the second limiting groove 302 are interconnected.

[0015] A rotating rod 203 is also provided on the force-applying part 201. The first limiting groove 301 and the second limiting groove 302 both have a T-shaped cross-section. The support frame 1 consists of a support plate 101 and legs 102 fixed to the support plate 101. Figure 4 As shown, the support plate 101 is provided with a threaded hole 103 for the passage of the actuating rod 2. The stroke of the actuating rod 2 is greater than the height of the support leg 102.

[0016] The support plate 101 is made of a steel plate with a length of 130mm, a width of 50mm, and a thickness of 50mm. The support leg 102 is made of two round steel bars with a length of 150mm and a diameter of 20mm. The support plate 101 and the support leg 102 are welded together to form the support frame 1. A bolt hole with a diameter of 16mm is reserved in the center of the support plate 101, and the actuating rod 2 passes through the threaded hole 103. In use, the two round steel bars of the support frame 1 support the side of the slide plate to provide support and bear the force. The clamping plate 3 is made of a steel plate with a length of 58mm, a width of 46mm, and a thickness of 20mm. The actuating rod 2 is 230mm long and 16mm in diameter. The force-applying part 201 is hexagonal, and the positioning part 202 is round-headed. In use, the round-headed side is placed in the second limiting groove 302 of the clamping plate 2.

[0017] In use, the actuating rod 2 passes through the slots (first limiting slot 301 and second limiting slot 302) in the clamping plate 3. The positioning part 202 (round end) of the actuating rod 2 is locked in the second limiting slot 302 and can rotate within the second limiting slot 302. The force-applying part 201 of the actuating rod 2 passes through the threaded hole 103. Then, the first limiting slot 301 is placed on the flat head side of the pin, and the two supporting round steels of the support frame 1 are pressed against the side of the track bed slide plate. The force-applying part 201 is twisted at a uniform speed to make the bolt extend outward. At the same time, through the bidirectional connection of the clamping plate 3, the pin is pulled outward until the pin and the slide plate are no longer under force, thus completing the pin removal work of the slide plate.

[0018] As can be seen, the tool of this application is simple to operate, lightweight and portable, safe and efficient. Compared with the "hammering" method, the pin removal process will not damage the finished product, ensuring construction quality and greatly improving construction safety. At the same time, the pin removal tool for turnout slide plates has a simple structure, and the raw materials for manufacturing this tool are steel plates, bolts, etc., which are readily available and inexpensive, reducing manufacturing costs.
