[0002] In order to meet the development needs of high-speed and heavy-haul railway transportation, various types of speed-up turnouts are gradually updated and laid on railway lines every year. High-speed trains will exert greater dynamic loads and impact forces on these turnouts. The maintenance of speed-up turnouts has become an important part of the daily work of railway speed-up track maintenance departments;
[0003] In order to maintain the stability of the slide plate in the switch, pins are installed in both the vertical and horizontal directions. When maintaining and replacing the slide plate, it is necessary to first remove all the pins on the slide plate. When removing the vertically installed pins, since there is enough space above the pins, it is relatively convenient to remove them. However, when removing the pins on the side of the slide plate, since there is a track on the slide plate and the space under the slide plate from the ground is limited, traditional removal tools are not applicable when removing the horizontally installed pins on the side of the slide plate, and only manual removal can be used. When manually removing the pins, multiple workers need to cooperate together, and the entire removal process takes a long time, seriously affecting the efficiency of slide plate maintenance and replacement.
[0004] Based on this, the utility model designs a device for removing pins of a slide plate to solve the above problems. Content of the Utility Model

[0025] The following will detail the embodiments of the utility model with reference to the accompanying drawings. However, the utility model can be implemented in many different ways defined and covered by the following.
[0026] Please refer to Figures 1-4 , the utility model provides a device for removing the pins on the sliding bed plate, which is used to remove the pins inserted on the sliding bed plate. The device for removing the pins on the sliding bed plate includes a fixing frame 1 and an ejection mechanism 2. A contact surface 11 is provided on the fixing frame 1. By contacting the side surface of the sliding bed plate through the contact surface 11, a fulcrum is provided for the ejection mechanism 2 to facilitate the application of force by the ejection mechanism 2. The ejection mechanism 2 includes an ejection rod 21 and an adjusting member 22 for adjusting the position of the ejection rod 21 relative to the contact surface 11. The adjusting member 22 and the contact surface 11 are distributed at both ends of the fixing frame 1 in the length direction. During operation, first, the contact surface 11 contacts the side of the sliding bed plate near the nail head. At this time, the sliding bed plate is between the contact surface 11 and the ejection rod 21. Immediately afterwards, the distance between the ejection rod 21 and the contact surface 11 is reduced by the adjusting member 22, so that the ejection rod 21 approaches and contacts the tip end face of the pin. Continuing to shorten the distance between the ejection rod 21 and the contact surface 11 by the adjusting member 22, since the distance between the ejection rod 21 and the contact surface 11 decreases, and the contact surface 11 cannot move due to contacting the side surface of the sliding bed plate, the ejection rod 21 will push the tip of the pin towards the contact surface 11 to achieve the removal of the pin. The removal of the pin is achieved through the cooperation of the fixing frame 1 and the ejection mechanism 2. The overall device has a simple structure, low manufacturing cost and convenient use. A single person can complete the work of removing the pins on the sliding bed plate, and at the same time, it can greatly shorten the time required for pin removal.
[0027] The first example of the contact surface 11. In this example, a clamping groove is opened on the bottom surface of the fixing frame 1, and the contact surface 11 is the side surface of the clamping groove. The side surface of the clamping groove contacts the side surface of the sliding bed plate.
[0028] The second example of the abutting surface 11. In this example, a convex platform protruding downward is fixedly installed on the bottom surface of the fixing frame 1, and the side surface of the convex platform is the abutting surface 11. The side surface of the convex platform abuts against the side surface of the slide plate.
[0029] Figure 3 This is an example of the ejection mechanism 2. In this example, the adjusting member 22 in the ejection mechanism 2 is a threaded sleeve, which is fixedly installed at one end of the fixing frame 1 away from the abutting surface 11. The ejector rod 21 is a lead screw, and the lead screw is in threaded fit with the threaded sleeve. The position of the lead screw relative to the abutting surface 11 is adjusted by rotating the lead screw.
[0030] In order to ensure that the pin is not interfered by the abutting surface 11 when the lead screw ejects the pin, the threaded sleeve and the abutting surface 11 are installed offset in the width direction of the mounting frame, so that when the lead screw is aligned with the pin, the abutting surface 11 and the pin are offset in the width direction of the fixing frame 1 to make way for the movement of the pin.
[0031] Or, as Figure 4 shown, a relief hole 12 is opened at one end of the fixing frame 1 close to the abutting surface 11. The relief hole 12 penetrates through the end face of the fixing frame 1 and the abutting surface 11. The height and length of the relief hole 12 are respectively greater than the height and length of the pin head. Before the abutting surface 11 abuts against the slide plate, the pin on the side surface of the slide plate is first aligned with the relief hole 12. When the side surface of the abutting surface 11 fits with the side surface of the slide plate, the pin head is just located in the relief hole 12, providing space for the subsequent movement of the pin and preventing the abutting surface 11 or the fixing frame 1 from interfering with the movement of the pin.
[0032] In some examples, a top plate 23 is rotatably installed at one end of the lead screw for contacting the pin. Because during the process of the lead screw ejecting the pin, the lead screw itself needs to rotate, and the pin cannot rotate, which will cause wear on the contact surface between the lead screw and the pin. In order to increase the service life of the lead screw and the pin, a top plate 23 is rotatably arranged at the end face where the lead screw contacts the pin. During the jacking process, the top plate 23 remains stationary relative to the pin, reducing the wear on the pin. At the same time, the lead screw and the pin are spaced apart by the top plate 23, reducing the wear of the lead screw, so as to reduce the wear on the lead screw and the pin when removing the pin and increase the service life of the pin and the lead screw.
[0033] Figure 3 An installation example of the top plate 23 is shown. In this example, a socket hole 24 is opened at one end of the lead screw for contacting the pin, and a plug rod 25 is installed on the side surface of the top plate 23. The top plate 23 is rotatably connected to the lead screw by inserting the plug rod 25 into the socket hole 24, and the top plate 23 is detachable from the lead screw, which is convenient for replacing the top plate 23 later.
[0034] In some examples, a hexagonal knob 26 is installed on the side of the lead screw that does not contact the pin, and the lead screw can be rotated by a wrench, which is more labor-saving.
[0035] Specifically, the hexagonal knob 26 is inserted and matched with the lead screw to achieve the detachable of the hexagonal knob 26. When it is inconvenient to rotate with a wrench, the hexagonal knob 26 can be replaced. The insertion hole for the hexagonal knob 26 to be inserted and matched with the lead screw is a regular polygon to prevent the hexagonal knob 26 from slipping.
[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
