Description

A ground rail type aluminum alloy mobile pulley

Technical Field

The present application relates to the field of mobile pulleys, and in particular to a ground rail type aluminum alloy mobile pulley.

Background Art

With the rapid development and growth of the automobile industry, automobile maintenance has also rapidly emerged as an important derivative industry. In the daily maintenance process, it is often encountered that the vehicle is damaged and cannot be moved, which requires the transfer and movement of the vehicle to be repaired. In this case, in order to facilitate vehicle inspection and maintenance, the transfer and movement of the vehicle to be inspected becomes a necessary operation. Among them, the use of mobile pulleys has become increasingly common. Mobile pulleys are specially designed tools that can easily move damaged or faulty vehicles from one location to another.

In the current automobile maintenance process, when a vehicle arrives at a maintenance center or vehicle maintenance area, the staff will conduct a preliminary inspection and assessment. If it is found that more in-depth maintenance operations are required, the vehicle needs to be moved to a fixed maintenance station. However, in the absence of appropriate tools, such as when the car breaks down and cannot move on its own, maintenance workers usually can only rely on manpower to push or pull the vehicle, move the vehicle to a fixed maintenance station, and then perform lifting and other operations to repair the vehicle.

With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: during vehicle maintenance, the vehicle to be inspected needs to be transported and moved. However, relying solely on manpower to transfer and move the vehicle consumes a lot of physical strength and involves certain risks, so there is room for improvement.

A floor rail type aluminum alloy mobile pulley comprises no less than two groups of floor rails, brackets and multiple groups of vehicle loading plates, each group of the floor rails being embedded in the ground; the brackets comprise eight groups of support assemblies vertically distributed in pairs and four groups of slide rails parallel in pairs, the extension direction of each group of the slide rails being perpendicular to the extension direction of the floor rails, and each group of the slide rails spans each group of the floor rails; the vertical lower end of each group of the support assemblies is slidably connected to the floor rails, and the two sides of the lower end surface of each group of the slide rails are respectively fixedly connected to the support assemblies inside the floor rails on each side; various vehicle loading plates comprise a plate surface and wheels rotatably connected to the four corners of the plate surface, each group of the vehicle loading plates is located above each group of the slide rails, and each group of the wheels on the same side is engaged and slidably connected to the slide rails.

By adopting the above technical scheme, the mobile pulley includes a ground rail, and the support assembly is slidably installed on the ground rail, so that the support assembly can move in the direction of the ground rail, and the upper end of the support assembly is fixedly connected with the slide rail, and the wheels of the vehicle loading plate are engaged and slid with the slide rail, so that the vehicle loading plate can move in the direction of the slide rail. In the process of automobile maintenance, the vehicle enters the ground rail position, and each set of wheels is located on the vehicle loading plate. At this time, the maintenance personnel push each set of support assemblies, and the car can slide in the direction of the ground rail and park at an appropriate position; when the position of the car needs to be further adjusted, the maintenance personnel can hold each set of vehicle loading plates and push them, and the car can move in the direction of the slide rail. In summary, the car to be repaired can be adjusted in two dimensions, the horizontal vertical direction and the vertical direction. By quickly moving the position of the car, it is convenient for maintenance personnel to carry out maintenance and improve work efficiency.

Preferably, the support assembly includes a connecting member for sliding connection with the ground rail and a first cylinder vertically installed above the connecting member, the first cylinder includes a cylinder body and a push rod inserted and slidably connected to the cylinder body, the lower end of the cylinder body is fixedly connected to the connecting member, and the upper end of the first cylinder is fixedly connected to the slide rail.

By adopting the above technical solution, the upper end of each group of first cylinders is fixedly connected to the slide rail. When the push rod extends out of the cylinder body, the first cylinder pushes the slide rail upward; and when the push rod contracts inward, the slide rail will also drop accordingly. Maintenance personnel can control the extension and retraction of the first cylinder to achieve the lifting and lowering of the vehicle, so that there is enough working space under the vehicle for maintenance personnel to enter.

Preferably, a rack is integrally formed on the horizontal upper end surface of each group of the ground rails, a motor is mounted on the connecting member, a gear is coaxially rotatably connected to the output shaft of the motor, and the gear is meshed with the rack for transmission.

By adopting the above technical solution, the horizontal ends of the second cylinder are respectively fixedly connected to the cylinder bodies of the second and third groups of the first cylinders inside the ground rail on the same side. When the second cylinder extends outward, it will drive the second and third groups of the first cylinders to slide to both sides. At this time, the front and rear wheel wheelbases can be adjusted according to specific needs to adapt to different vehicle models or needs. In addition, the installation of the second cylinder improves the integrity between the groups of slide rails on both sides, improves the overall structural strength, and is less likely to shake.

Preferably, each group of the slide rails includes two groups of limit screws, and the two groups of limit screws are threadedly connected to the upper end surface of the slide rails.

Preferably, two groups of the slide rails on the same side are tension-connected with horizontally distributed cross bars.

By adopting the above technical solution, a horizontally distributed cross bar is provided between the two sets of slide rails on the same side for tension connection, which can provide further support and fixation in the horizontal direction. When the slide rail needs to withstand a large horizontal force or vibration, the use of a cross bar for tension connection can effectively disperse and transmit the external force, evenly distribute the external force to each slide rail, and improve the overall structural strength and bearing capacity.

Preferably, two groups of rollers are rotatably mounted on the lower end of the connecting member, and the upper end surface of the ground rail is provided with two groups of parallelly distributed grooves; each group of the rollers is slidably mounted inside the grooves.

By adopting the above technical solution, two sets of parallel grooves are provided on the upper end surface of the ground rail, which can guide the pulley to achieve smooth movement on the ground rail along a specific direction. By installing the pulley in the groove, a relatively sliding contact surface is formed between the pulley and the ground rail. Compared with direct contact with the surface of the ground rail, the use of the pulley can greatly reduce friction and achieve labor-saving operation.

Preferably, the loading plate is made of aluminum alloy, including a plate surface and two groups of guide plates, the upper end surface of the plate surface is integrally formed with a first anti-slip pattern; the two groups of guide plates are respectively fixedly connected to the two ends of the plate surface in the length direction; the end of the guide plate away from the plate surface is inclined downward; the guide plate includes two groups of handles and several groups of second anti-slip patterns, the upper end surface of the guide plate is integrally formed with a second anti-slip pattern, and the handles are recessed at both ends of the guide plate away from the plate surface.

By adopting the above technical scheme, aluminum alloy is used as the material of the vehicle loading plate, which is lighter than other materials, and can improve the load-bearing capacity of the vehicle loading plate, while reducing the total weight of the entire pulley system; the guide plates at both ends of the plate surface are tilted downward to facilitate the vehicle to get on and off the loading plate, and a handle is provided on the end of the guide plate away from the plate surface. Maintenance personnel can move the position of the vehicle loading plate by grasping the handle. The upper end surface of the vehicle loading plate surface and the upper end surface of the guide plate surface are both provided with anti-slip textures to increase friction and prevent wheels from slipping.

In summary, the car to be repaired can be quickly adjusted in the horizontal, vertical and vertical directions. By quickly moving the position of the car, it is convenient for maintenance personnel to carry out maintenance and improve work efficiency.

2. The slide rail is fixedly connected to the first cylinder, and the slide rail is raised and lowered by controlling the extension and retraction of the first cylinder, so that there is enough working space under the vehicle for maintenance personnel to enter; the motor drives the gear to rotate, and no manpower is required to push it.
