Description

Technical Field

[0001] This utility model belongs to the technical field of wind-resistant rail clamps, specifically a wind-resistant rail clamp. Background Technology

[0002] Wind-resistant rail clamps are safety devices specifically designed to enhance the stability of cranes under windy conditions.

[0003] Wind-resistant rail clamps, also known as windproof rail clamps, are primarily used to prevent cranes (especially tower cranes, bridge cranes, gantry cranes, and other similar cranes) from swaying, tilting, or shifting due to wind force in strong winds, thus ensuring construction safety. They clamp the rails to ensure a tight connection between the crane and the ground, improving the crane's wind resistance.

[0004] Conventional wind-resistant rail clamps use bolts to clamp and fix the rail body on both sides. Users need to operate multiple wind-resistant rail clamps multiple times, and the operation requires frequent tightening of bolts, which makes fixing the wind-resistant rail clamps cumbersome and inconvenient, reducing the effectiveness of the device.

[0005] Therefore, a wind-resistant rail clamp is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies and solve the problems mentioned in the background art, a wind-resistant rail clamp is proposed.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The wind-resistant rail clamp of this utility model includes a transverse support rod, a limit groove is opened inside the transverse support rod, a motor groove is opened inside the transverse support rod, an electric motor is detachably installed inside the motor groove, a threaded rod is fixedly connected to the output end of the electric motor, an internal threaded sleeve is threadedly connected to the outer side of the threaded rod, a fixing rod is fixedly installed at the bottom of the internal threaded sleeve, and a left clamping rod is fixedly connected to the bottom of the fixing rod. The left clamping rod is located directly below the transverse support rod. The cooperation of the electric motor, the threaded rod and the internal threaded sleeve reduces the tedious steps of repeatedly using bolts for fixing and improves installation efficiency.

[0008] Preferably, a bearing is installed at the connection between the threaded rod and the limiting groove, and the threaded rod is rotatably connected to the limiting groove through the bearing; by fixing the bearing inside the limiting groove, it plays a positioning role when the threaded rod rotates, ensuring the smoothness and reliability of the rotation, maintaining linear rotation without any tilting or offset, and conveniently reducing the friction between the threaded rod and the limiting groove.

[0009] Preferably, a right clamping rod is fixedly connected to one side of the bottom of the transverse support rod, and anti-slip textures are evenly provided on the opposing surfaces of the left and right clamping rods; the right clamping rod installed in this device is fixedly connected to the transverse support rod, the purpose of which is to clamp the track by moving only one side of the clamping rod, and the internal arrangement of the left and right clamping rods can increase the friction.

[0010] Preferably, the cover plate and the heat dissipation holes on it not only facilitate the replacement and maintenance of components inside the motor slot, but also allow the heat generated inside to be exchanged with the outside cold air through these heat dissipation holes, thereby achieving effective heat dissipation and cooling, and ensuring the stable operation of the equipment.

[0011] Preferably, the limiting groove and the motor groove are two different areas; by carefully designing and opening two different areas inside the transverse support rod, different types of components can be installed in a categorized manner, which not only optimizes space utilization and maximizes the value of every inch of space, but also improves the flexibility and convenience of component installation.

[0012] Preferably, the cover plate is positioned directly above the motor slot; by positioning the cover plate directly above the motor slot, the heat generated by the electric motor during operation can be better dissipated to the outside, reducing the temperature inside the motor slot, ensuring the working safety of the electric motor, and improving the protection effect of the electric motor.

[0013] The beneficial effects of this utility model are:

[0014] This utility model provides a wind-resistant rail clamp. By setting up a precise matching mechanism of electric motor, threaded rod and internal threaded sleeve, a highly efficient and controllable clamping action is achieved. The electric motor serves as the power source, and its rotational motion is transmitted to the internal threaded sleeve through the threaded rod, thereby driving the internal threaded sleeve to move linearly along the axial direction of the threaded rod. This movement process is cleverly transformed into pushing or pulling the left clamping rod connected to the bottom of the fixed rod, so that the left clamping rod can be precisely displaced directly below the transverse support rod, reducing the tedious steps of repeatedly using bolts for fixing and improving installation efficiency.

[0015] This utility model provides a wind-resistant rail clamp, which, by fixing the bearing inside the limiting groove, plays a positioning role when the threaded rod rotates, ensuring the smoothness and reliability of the rotation, maintaining linear rotation without any tilting or deviation, and conveniently reducing the friction between the threaded rod and the limiting groove, effectively avoiding unnecessary wear, thereby greatly increasing the service life of the threaded rod.

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figures 1-5This utility model provides a wind-resistant rail clamp, including a transverse support rod 1; a mounting bracket 14 is fixedly connected to the top of the transverse support rod 1; characterized in that: a limiting groove 2 is formed inside the transverse support rod 1, a motor groove 3 is formed inside the transverse support rod 1, an electric motor 4 is fixedly connected inside the motor groove 3, a threaded rod 5 is fixedly connected to the output end of the electric motor 4, an internal threaded sleeve 7 is threadedly connected to the outer side of the threaded rod 5, a fixing rod 8 is fixedly installed at the bottom of the internal threaded sleeve 7, and a left clamping rod 9 is fixedly connected to the bottom of the fixing rod 8, the left clamping rod 9 being located directly below the transverse support rod 1; during operation, the lifting equipment and the transverse support rod 1 are fixedly connected by using the mounting bracket 14; by setting a precise matching mechanism of the electric motor 4, the threaded rod 5 and the internal threaded sleeve 7, a high-performance rail clamp is achieved. The effective and controllable clamping action is achieved through the electric motor 4 as the power source. Its rotational motion is transmitted to the internal threaded sleeve 7 via the threaded rod 5, which in turn drives the internal threaded sleeve 7 to move linearly along the axis of the threaded rod 5. This movement is cleverly transformed into pushing or pulling the left clamping rod 9 connected to the bottom of the fixed rod 8, allowing the left clamping rod 9 to move precisely below the transverse support rod 1. The movement of the left clamping rod 9 is not isolated; it works in coordination with the right clamping rod 10 located on the other side of the transverse support rod 1. When the left clamping rod 9 approaches the track under the drive of the electric motor 4, the right clamping rod 10 acts as a cooperating part to clamp the track together. The double-sided clamping design not only enhances the stability and reliability of the clamping but also reduces the tedious steps of repeatedly using bolts for fixing, thus improving installation efficiency.

[0027] Furthermore, such as Figure 2 and Figure 4 As shown, a bearing 6 is installed at the connection between the threaded rod 5 and the limiting groove 2. The threaded rod 5 is rotatably connected to the limiting groove 2 through the bearing 6. During operation, by fixing the bearing 6 inside the limiting groove 2, it plays a positioning role when the threaded rod 5 rotates, ensuring the smoothness and reliability of the rotation, maintaining linear rotation without any tilting or deviation, and conveniently reducing the friction between the threaded rod 5 and the limiting groove 2, effectively avoiding unnecessary wear, thereby greatly increasing the service life of the threaded rod 5.

[0028] Furthermore, such as Figure 1 and Figure 4As shown, a right clamping rod 10 is fixedly connected to one side of the bottom of the transverse support rod 1. Anti-slip textures 11 are evenly provided on the opposite surfaces of the left clamping rod 9 and the right clamping rod 10. During operation, the right clamping rod 10 installed on the device is connected to the transverse support rod 1 in a robust manner, ensuring that the track can be effectively and stably clamped when only one side of the clamping rod moves. This single-sided operation design not only simplifies the operation process but also improves the response speed and efficiency of the clamping action. In order to further enhance the stability and reliability of the clamping, the friction between the clamping rod and the contact surface of the track can be significantly increased inside the left clamping rod 9 and the right clamping rod 10, thereby effectively preventing slippage or loosening caused by external forces during the clamping process, improving the firmness of the clamping, and ensuring the stable operation of the equipment under complex or harsh working conditions, providing a solid and reliable guarantee for various application scenarios.

[0029] Furthermore, such as Figure 5 As shown, a cover plate 12 is installed on one side above the horizontal support rod 1. The cover plate 12 is located directly above the motor slot 3. Strip-shaped air outlets 13 are evenly distributed on the upper side of the cover plate 12. During operation, the removable cover plate 12 allows for easy observation of the inside of the motor slot 3, thus facilitating the replacement and maintenance of the electric motor 4. This improves the maintainability of the equipment and ensures that components can be quickly handled when malfunctions occur, effectively reducing production losses caused by downtime for maintenance. The multiple strip-shaped air outlets 13 above the cover plate 12 play a crucial role in heat dissipation. When the device inside the motor slot 3 is running, it generates a large amount of heat. If this heat is not dissipated in time, it may cause the components to overheat, thereby affecting their performance and lifespan. The design of the cover plate 12 and the strip-shaped air outlets 13 above it not only facilitates the replacement and maintenance of the components inside the motor slot 3, but also allows the heat generated inside to be exchanged with the outside cold air through these strip-shaped air outlets 13, thereby achieving effective heat dissipation and cooling, and ensuring the stable operation of the equipment.

[0030] Furthermore, such as Figure 2As shown, the limiting groove 2 and the motor groove 3 are two different areas. During operation, by carefully designing and opening two different areas inside the transverse support rod 1, different types of components can be installed efficiently and in a categorized manner. This not only optimizes space utilization, maximizing the value of every inch of space, but also improves the flexibility and convenience of component installation. The first area can be specifically used to install heavy or complex components. The reinforced design and load-bearing capacity of this area ensure the stability and safety of these key components. The second area can be used for customized installation of drive components. Through reserved interfaces, slots, or special fixing devices, these components can be easily connected and maintain good working condition, improving the compactness and aesthetics of the overall structure. It also facilitates subsequent maintenance, upgrades, and troubleshooting, providing a strong guarantee for the long-term stable operation of the equipment.

[0031] Furthermore, such as Figure 1 and Figure 3 As shown, the cover plate 12 is set directly above the motor slot 3. During operation, by setting the cover plate 12 directly above the motor slot 3, the heat generated by the electric motor 4 during operation can be better dissipated to the outside, reducing the temperature inside the motor slot 3, ensuring the working safety of the electric motor 4, and improving the protection effect of the electric motor 4.

[0032] Working principle: By starting the electric motor 4, the electric motor 4 drives the threaded rod 5 on one side to rotate. The rotation of the threaded rod 5 causes the inner threaded sleeve 7 to move parallel to the outside of the threaded rod 5, so that the bottom left clamping rod 9 moves closer to the right clamping rod 10 to clamp the track. The cover plate 12 is set to allow the replacement of the components inside the motor slot 3. Multiple strip-shaped air outlets 13 are opened above the cover plate 12. The purpose is to dissipate the heat generated by the device inside the motor slot 3 during use. The design of the cover plate 12 and the strip-shaped air outlets 13 above it not only provides convenience for the replacement and maintenance of the components inside the motor slot 3, but also allows the heat generated inside to be exchanged with the outside cold air through these strip-shaped air outlets 13, thereby achieving effective heat dissipation and cooling, and ensuring the stable operation of the equipment.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
