Description

Technical Field

[0001] This utility model relates to the field of rail construction technology, specifically to a clamping device for rail construction that can be quickly positioned and calibrated. Background Technology

[0002] Rail construction is a core component of railway construction, involving multiple aspects such as rail laying, connection, adjustment, and quality control. Its construction quality directly affects the smoothness, safety, and service life of the railway line. In rail construction, clamping devices are one of the key pieces of equipment, mainly used for fixing, hoisting, moving, and precisely positioning rails to ensure the safety and efficiency of the construction process.

[0003] However, some existing clamping devices require manual rotation of the threaded rod by the operator to adjust the distance between the two positioning frames to clamp the rail. This clamping method requires rotating the threaded rod several times, which not only increases the workload of the operator but also reduces the clamping efficiency of the rail. Furthermore, the device requires reverse rotation to release the rail, which is not only cumbersome but also affects the efficiency of the positioning frame reset, thus reducing the applicability of the device. Utility Model Content

[0004] The purpose of this invention is to provide a clamping device for rail construction that can be quickly positioned and calibrated, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for rapid positioning and calibration in rail construction, comprising a mounting base and a connecting ring fixed to its top, and further comprising:

[0006] A positioning frame is rotatable at two points on the surface of the mounting base. A fixed rod is rotatably connected to the surface of the mounting base. A movable frame is slidably connected to the surface of the fixed rod. Fixed grooves are provided at two points on the surface of the fixed rod. A positioning groove is provided on one side of the inner cavity of the fixed groove.

[0007] Positioning rods are fixed to both sides of the inner cavity of the movable frame. A support rod is rotatably connected to the surface of the movable frame. A fixed seat is rotatably connected to the other end of the support rod. A locking mechanism is installed on the surface of the mounting seat.

[0008] Preferably, the locking mechanism includes a connecting frame fixed to the surface of the mounting base and a locking rod sliding on its inner wall, wherein a magnet is embedded in the inner wall of the fixing rod.

[0009] Preferably, a locking block is fixedly connected to the surface of the locking rod, and the surface of the locking block is slidably connected to the inner wall of the fixing rod.

[0010] Preferably, the locking rod is made of iron, and the magnet is used in conjunction with the locking rod.

[0011] Preferably, two actuating rods are fixedly connected to the surface of the fixed rod at two locations, and the actuating rods are used in conjunction with the mounting base.

[0012] Preferably, there are several positioning grooves, and the height of the inner cavity of the positioning groove is the same as the width of the inner cavity of the fixing groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention, through the cooperation of the positioning rod and the fixing groove, allows for a significant adjustment of the movable frame, making it more convenient to clamp the rails. Furthermore, the locking mechanism limits the movement of the fixing rod, making rail clamping more convenient and efficient, and improving the device's overall performance.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5As shown, a clamping device for rapid positioning and calibration of rails during construction includes a mounting base 1. A connecting ring 2 is fixedly connected to the top of the mounting base 1, facilitating the hoisting of the device and thus the rail. Positioning frames 3 are rotatably connected to two points on the surface of the mounting base 1. The positioning frames 3 can clamp and limit the rail by their shape, thereby connecting the device to the rail. A fixed rod 4 is rotatably connected to the surface of the mounting base 1, and a movable frame 5 is slidably connected to the surface of the fixed rod 4. Fixed grooves 6 are formed at two points on the surface of the fixed rod 4. A positioning groove 7 is formed on one side of the inner cavity of the fixed groove 6. The number of positioning grooves 7 is several, and the height of the inner cavity of the positioning groove 7 is the same as the width of the inner cavity of the fixed groove 6. The movable frame 5 can enter the positioning groove 7 once it can enter the fixed groove 6. Positioning rods 8 are fixedly connected to both sides of the inner cavity of the movable frame 5. The surface of the positioning rods 8 is slidably connected to the inner walls of both the fixed groove 6 and the positioning groove 7. This allows the positioning rods 8 to be moved into the fixed groove 6, and the position of the movable frame 5 to be adjusted. After adjusting to the appropriate position, the fixed rod 4 is rotated to embed the positioning rods 8 into the positioning groove 7, thus limiting the movable frame 5 and facilitating its subsequent use. Furthermore, by adjusting the positioning rods 8 to different positions within the positioning groove 7, the position of the movable frame 5 can be adjusted, allowing it to be fixed at different positions on the surface of the fixed rod 4. A support rod 9 is movably connected to the other end of the movable frame 5, and a fixed seat 10 is rotatably connected to the other end of the support rod 9. The surface of the fixed seat 10 is fixedly connected to the surface of the positioning frame 3. Under this action, the tilt angle of the support rod 9 can be adjusted by adjusting the position of the movable frame 5, thereby adjusting the distance between the two positioning frames 3. After the movable frame 5 is moved below the surface of the fixed rod 4, the two positioning frames 3 can be brought closer together with the cooperation of the support rod 9 and the fixed seat 10, which facilitates the clamping of the rail. This not only makes it more convenient and effectively improves the clamping efficiency of the device, but also allows the positioning rod 8 to move inside the fixed groove 6 when releasing the rail, so that the movable frame 5 can move significantly through the support rod 9. The position of the positioning frame 3 is adjusted to make it easier for the positioning frame 3 to return to its original position, thus facilitating subsequent use. The surface of the mounting base 1 is equipped with a locking mechanism 11, which can limit the fixed rod 4, so that it can be relatively stable when it does not need to be rotated, avoiding its instability from affecting the limiting effect on the movable frame 5, and effectively improving the stability of the fixed rod 4. Two toggle rods 13 are fixedly connected to the surface of the fixed rod 4. The toggle rods 13 are used in conjunction with the mounting base 1. Under this action, it is more convenient to rotate the fixed rod 4 when it is necessary, providing the operator with an effective force application point, thereby improving the clamping efficiency of the device on the rail.

[0023] The locking mechanism 11 includes a connecting frame 111 fixed to the surface of the mounting base 1. A locking rod 112 is slidably connected to the inner wall of the connecting frame 111. The surface of the locking rod 112 is slidably connected to the inner wall of the fixed rod 4. Under this action, the locking rod 112 can be limited after entering the interior of the fixed rod 4, preventing it from rotating easily, effectively improving the stability of the fixed rod 4 when rotation is not required. A magnet 113 is embedded in the inner wall of the fixed rod 4. The locking rod 112 is made of iron. The magnet 113 works in conjunction with the locking rod 112. Under this action, it can... With the cooperation of the magnet block 113, the locking rod 112 is limited, preventing it from moving easily and affecting the limiting effect on the fixing rod 4, thus effectively improving the stability of the fixing rod 4. The locking rod 112 is fixedly connected to the surface of the locking rod 112, and the surface of the locking block 12 is slidably connected to the inner wall of the fixing rod 4. Under this action, the locking rod 112 can be blocked by the locking block 12, so that the locking rod 112 will not easily detach from the connecting frame 111, thus preventing the locking rod 112 from detaching from the inside of the connecting frame 111 and affecting subsequent use.

[0024] It is worth noting that the technical features such as the mounting base 1 and the positioning frame 3 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0025] Working principle: First, the rail is positioned between the two positioning frames 3. Then, the operator rotates the fixed rod 4, causing the positioning rod 8 to move into the fixed groove 6. The position of the movable frame 5 is then significantly adjusted. With the cooperation of the movable frame 5, support rod 9, and fixed seat 10, the positioning frame 3 is adjusted to clamp the rail. Next, the fixed rod 4 is rotated to slide the positioning rod 8 into the positioning groove 7, thus limiting the movable frame 5. Then, with the cooperation of the locking rod 112, the fixed rod 4 is limited. Finally, the rail is hoisted using a crane and connecting ring 2. This method is not only convenient but also allows for significant adjustment of the position of the positioning frame 3, making rail clamping easier and faster, effectively improving the device's applicability. After hoisting, the operator releases the limitation on the fixed rod 4, rotates the fixed rod 4 to move the positioning rod 8 into the fixed groove 6, and then quickly releases the clamping of the rail by moving the movable frame 5.
