As an important component for fixing the rail, the installation quality of the elastic rail clip directly affects the stability and safety of the railway line. Traditionally, the installation of elastic rail clips mostly adopts manual or semi-mechanized methods, which not only have low efficiency, but also the installation quality is easily affected by human factors, and there are relatively large potential safety hazards.

[0003] With the continuous development of railway technology and the increasing requirements for operation efficiency, the technology of quickly, accurately and stably installing elastic rail clips has become the focus of the industry. In this context, the research and application of quick elastic rail clip installing machines are particularly important. However, the existing quick elastic rail clip installing machines often have deficiencies in the design of the clamping mechanism, such as insufficient clamping force and poor stability, which directly affect the installation efficiency and installation quality of the elastic rail clip.

[0004] In view of the above problems, it is particularly important to design a clamping mechanism for a quick elastic rail clip installing machine that is efficient and stable. This clamping mechanism needs to be able to firmly clamp the rail, prevent lateral and vertical displacement during installation, so as to ensure that the elastic rail clip can be accurately and quickly installed in place. At the same time, this clamping mechanism should also have the characteristics of simple structure, convenient operation and easy maintenance to adapt to different working environments and operation requirements.

Detailed Embodiment

[0031] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0032] Embodiment 1: As shown in Figures 1-4 , a clamping mechanism for a quick elastic clip installing machine, comprising a clamping frame 301, clamping plates 302 symmetrically installed on the lower side of the clamping frame, and the clamping frame is rotatably connected to the clamping plates; at the bottom position inside the clamping plates, a clamping assembly for clamping the rail web and restricting the vertical displacement of the clamping frame is installed. The clamping assembly includes a rail web wheel 305 for clamping the rail web and a T-shaped wheel 306 for restricting the vertical displacement of the installing machine. Specifically, the rail web wheel 305 and the T-shaped wheel 306 are respectively rotatably installed inside the clamping plates through a rail web wheel shaft 315 and a T-shaped wheel shaft 314. Two T-shaped wheels are installed, and the rail web wheel 305 is installed at the bottom position of the clamping plate 302. The two T-shaped wheels and the rail web wheel are distributed in a triangular shape. A keyway 316 is correspondingly formed on the clamping plate 302 and the rail web wheel shaft 315, and the rail web wheel shaft 315 and the clamping plate 302 are connected by a nut and a key pin 317, that is, the rail web wheel shaft 315 is fixedly installed on the clamping plate and cannot rotate.

[0033] The design of the above clamping assembly has the following advantages: (1) Enhance clamping stability: The rail web wheel directly acts on the rail web part of the rail. Through its rotatable installation method, it can closely fit and effectively clamp the rail, preventing the rail from sliding or shifting during the installation process. At the same time, the two T-shaped wheels and the rail web wheel are distributed in a triangular shape, and this stable geometric structure further enhances the clamping effect of the clamping assembly on the rail, ensuring the stability during the installation process. (2) Restrict vertical displacement: The design of the T-shaped wheels not only plays an auxiliary clamping role, but more importantly, they can restrict the vertical displacement of the installing machine. Due to the special shape of the T-shaped wheels, when they contact the rail and are subjected to pressure, an upward reaction force will be generated, and this force is transmitted to the clamping frame through the clamping plate, thereby effectively restricting the vertical movement of the clamping frame. This is crucial for maintaining the stability of the installing machine during operation. (3) Improve adaptability: Both the rail web wheel and the T-shaped wheel are rotatably installed inside the clamping plate. This design enables the clamping assembly to flexibly adapt to rails of different specifications and shapes. Whether the width or height of the rail web changes, the clamping assembly can ensure close fit with the rail by adjusting its position and angle, thereby improving the adaptability and flexibility of the clamping mechanism. (4) Since both the rail web wheel and the T-shaped wheel are rotatably installed, they can reduce the direct friction with the rail during the clamping process, thereby reducing the risk of wear and damage. This design not only improves the service life of the clamping assembly, but also reduces the noise and vibration generated by wear, enhancing the overall working environment and user experience.

[0034] A push plate mechanism is installed on the outer side of the clamping plate, which enables the clamping assembly to move toward the rail 318 to clamp the rail and limit the lateral and vertical deviation of the clamping frame; the push plate mechanism includes a thrust handle 303, which is hingedly installed on the outer side of the clamping plate, and the thrust handle is connected to the clamping plate through a pin shaft. A tension spring 304 is installed between the clamping frame and the clamping plate, and two groups of tension springs are symmetrically installed.

[0035] The design of the push plate mechanism has the following advantages: (1) Enhanced clamping force: The push plate mechanism uses the design of the push handle to enable the operator to easily apply thrust to push the clamping assembly toward the rail, thereby achieving tight clamping of the rail. This design not only improves the efficiency and strength of clamping, but also ensures the stability and reliability of the clamping process. (2) Limiting displacement: When the push handle is pushed, the clamping assembly moves toward the rail and fits tightly. In this process, not only the rail is clamped, but also the lateral and vertical displacement of the clamping frame is limited through the interaction force between the clamping assembly and the rail. This double guarantee ensures that the installation machine can maintain a stable posture during use, improving installation accuracy and safety. (3) Buffering and resetting: The tension spring installed between the clamping frame and the clamping plate plays a role in buffering and resetting. During the clamping process, the tension spring can absorb part of the impact force and reduce the vibration and noise caused by sudden clamping. At the same time, after the clamping is completed, the elastic force of the tension spring can also help the clamping plate return to its initial position to prepare for the next clamping operation. This design not only improves the durability of the clamping mechanism, but also simplifies the operation process. (4) Improve the convenience of operation: The thrust handle is hingedly installed on the outside of the clamping plate and is connected to the clamping plate through a pin. This design allows the thrust handle to rotate flexibly, making it convenient for the operator to apply thrust at different angles and positions. At the same time, the symmetrical installation of the tension spring also ensures that the clamping mechanism can maintain balance when under force, further improving the convenience and stability of operation. (5) Reduce maintenance costs: The structure of the push plate mechanism and its related components is relatively simple and easy to disassemble and replace. This enables the operator to quickly complete the relevant work when maintenance or replacement of parts is required, reducing maintenance costs and time costs. At the same time, the simple structure also reduces the failure rate and improves the reliability and service life of the clamping mechanism.

[0036] A limiting mechanism is installed between the clamping frame and the clamping plate, and the limiting mechanism is used to lock the position of the clamping plate. With respect to the limiting mechanism, the limiting mechanism includes a limiting slot 307 provided on the clamping plate; limiting holes 308 are symmetrically provided on both sides of the clamping frame, and limiting pins 309 and reset springs 310 are installed in the limiting holes, and the reset spring is sleeved on the limiting pin, and a limiting boss 311 is installed on the limiting pin at a position corresponding to the bottom of the reset spring, and the limiting pin is opposite to the limiting hole; a spring cover plate 312 is installed above the limiting hole; and a T-shaped handle 313 is installed on the upper side of the limiting pin.

[0037] The design of the above-mentioned limit mechanism has the following advantages: (1) Enhance clamping stability: Through the mutual cooperation of the limit card slot, the limit pin and the return spring, the limit mechanism realizes the precise locking of the position of the clamping plate. When the clamping plate moves to the predetermined position, the limit pin automatically pops into the limit card slot under the action of the return spring, thus firmly fixing the position of the clamping plate. This design effectively prevents the clamping plate from shifting due to vibration or external forces during operation, enhancing the stability of the clamping mechanism. (2) Improve operation convenience: The T-shaped handle installed on the upper side of the limit pin enables the operator to conveniently control the entry and exit of the limit pin. When it is necessary to adjust the position of the clamping plate, simply pull the T-shaped handle gently to make the limit pin withdraw from the limit card slot, thus unlocking the clamping plate. This design simplifies the operation process and improves the operation efficiency. (3) Protect the return spring: The installation of the spring cover plate not only plays a role in dust and dirt prevention, but also protects the return spring from being eroded by the external environment. At the same time, the spring cover plate also limits the expansion range of the return spring, preventing it from being damaged or failing due to excessive expansion. This design extends the service life of the return spring and improves the reliability of the limit mechanism. (4) Ensure safety performance: The setting of the limit boss prevents the limit pin from popping out of the limit hole excessively under the action of the return spring, thus avoiding potential safety hazards caused by the detachment of the limit pin. This design ensures the stability and safety of the limit mechanism in the locked state. (5) Strong adaptability: The design of the limit mechanism takes into account the adaptability under different working environments and operation requirements. By adjusting the positions and quantities of the limit card slots and the limit holes, it can adapt to clamping plates of different specifications and shapes as well as different clamping requirements. This design improves the flexibility and versatility of the limit mechanism. In summary, the design of the limit mechanism shows significant beneficial effects in enhancing clamping stability, improving operation convenience, protecting the return spring, ensuring safety performance and improving adaptability.

[0038] The working principle of the clamping mechanism is as follows: After the installation machine is placed on the rail, the clamping plate is rotated by pushing the thrust handle, so that the rail waist wheel presses against the rail waist. At the same time, the rectangular spring pushes the limit pin to move downward to the limit card slot to lock the limit plate; when the installation machine passes through the door or is disassembled, the limit pin is pulled upward by the T-shaped handle to pull the limit pin out of the limit card slot, and the tension spring drives the clamping plate to rotate upward to lift the rail waist wheel off the rail waist, making the installation and disassembly more convenient. The simple operation is beneficial for the staff to quickly master the use of the installation machine.
