Description

Technical Field

[0001] This utility model relates to the field of vehicle frame clamping technology, and in particular to a safety vehicle frame clamping device. Background Technology

[0002] Aerial work platforms (ALPs) are vehicles with a height of 3 meters or more that use electric and hydraulic systems for vertical lifting operations. As a specialized engineering vehicle, ALPs require stable clamping devices to ensure their safety and stability. The design of their frame clamps must fully consider the needs of engineering practice. For example, the clamps need to be adaptable to different models and specifications of ALP frames to ensure versatility and flexibility. Simultaneously, the clamps must possess sufficient strength and rigidity to withstand various loads and impacts on the frame during operation, and they must firmly hold the frame in place to prevent loosening or detachment during operation.

[0003] When the clamping method for fixing the side of the frame is not simple, the frame may slide horizontally, affecting the efficiency of operation. In view of this, a safe frame clamp is provided. Utility Model Content

[0004] The main purpose of this utility model is to provide a safe frame clamp to solve the problem that the horizontal sliding of the frame affects the work efficiency when the clamp proposed in the related technology is not simple in fixing the side of the frame.

[0005] To achieve the above objectives, according to one aspect of the present invention, a safety frame clamp is provided, including a lower clamping plate, with fixed plates fixedly disposed at both ends on one side of the lower clamping plate, an upper clamping plate slidably disposed on the fixed plates, and side plates for limiting the left and right movement of the frame symmetrically disposed inside the upper clamping plate, a rubber tube fixedly connected to one end of the side plate, and a retractable corrugated tube fixedly disposed at the center of the bottom of the upper clamping plate, the other end of the rubber tube being fixedly connected to the inner wall of the corrugated tube.

[0006] Furthermore, an anti-slip pad is fixedly provided on the side wall of the upper clamping plate, and an arc-shaped groove is formed at the center of the anti-slip pad. One end of the corrugated pipe is fixedly connected to the inner wall of the groove.

[0007] Furthermore, the side plate is inverted L-shaped, and a limiting block is fixedly connected to each side plate. The upper clamping plate is symmetrically provided with sliding grooves, and the limiting block is slidably installed in the sliding groove.

[0008] Furthermore, when the upper clamping plate and the lower clamping plate approach each other to clamp the frame, the side plate slides outward, and the distance between the protruding ends of the side plate is 5~10cm.

[0009] Furthermore, slots are provided at both ends of the other side of the lower clamping plate, and connecting rods are rotatably engaged in the slots.

[0010] Furthermore, both ends of the upper clamping plate on the same side are provided with through holes.

[0011] Furthermore, several shock-absorbing rubber pads are fixedly installed inside the lower clamping plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In this type of safety frame clamp, a corrugated tube and a rubber tube are provided. When the corrugated tube is subjected to pressure on the surface of the frame, it will gradually shorten and push the rubber tube to bend, thereby pushing the side plate to slide outward. This allows the clamp to automatically adapt to frames of different sizes and provide them with stable lateral clamping force, preventing the frame from moving horizontally during the clamping process.

[0014] 2. In this type of safety frame clamp, a connecting rod is provided to provide stable support between the upper and lower clamping plates. This not only enhances the overall stability of the clamp but also improves its load-bearing capacity, ensuring that the frame will not be displaced or damaged during the clamping process.

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0027] Please see Figures 1-7 As shown, the purpose of this embodiment is to provide a safety frame clamp, including a lower clamping plate 1. Both ends of one side of the lower clamping plate 1 are fixedly provided with fixing plates 11. An upper clamping plate 2 is slidably provided on the fixing plates 11. Side plates 5 for limiting the left and right movement of the frame are symmetrically slidably provided inside the upper clamping plate 2. A rubber tube 51 is fixedly connected to one end of the side plate 5. A retractable corrugated tube 3 is fixedly provided at the center of the bottom of the upper clamping plate 2. The other end of the rubber tube 51 is fixedly connected to the inner wall of the corrugated tube 3.

[0028] An anti-slip pad 21 is fixedly installed on the side wall of the upper clamping plate 2. Its main purpose is to increase the friction between the upper clamping plate 2 and the frame, prevent the frame from sliding during clamping, and ensure the stability of the clamp. An arc-shaped groove 211 is opened in the center of the anti-slip pad 21. One end of the corrugated tube 3 is fixedly connected to the inner wall of the groove 211, and the other end of the corrugated tube 3 is a closed design. This means that the corrugated tube 3 forms a closed space inside to accommodate one end of the rubber tube 51 and ensure that the rubber tube 51 can bend smoothly when pushed by the corrugated tube 3. The closed end design also prevents external impurities or liquids from entering the interior of the corrugated tube 3, ensuring the durability and reliability of the corrugated tube 3.

[0029] The rubber tube 51 is fixedly connected to the closed end side wall of the corrugated tube 3. The rubber tube 51 has good flexibility and elasticity, and can bend when subjected to external force. When the corrugated tube 3 is gradually shortened by the pressure of the frame surface, the rubber tube 51 will bend towards the side plate 5. This bending characteristic allows the rubber tube 51 to push the side plate 5 to slide outward, thereby fixing the left and right positions of the frame.

[0030] The side plate 5 is inverted L-shaped. The inverted L-shaped structure gives the side plate 5 a vertical part and a horizontal part. The vertical part is used to contact the frame and provide support, while the horizontal part slides horizontally in the upper clamping plate 2. Limiting blocks 52 are fixedly connected to each side plate 5. The upper clamping plate 2 is symmetrically provided with sliding grooves 22, and the limiting blocks 52 are slidably installed in the sliding grooves 22.

[0031] When the upper clamping plate 2 and the lower clamping plate 1 approach each other to clamp the frame, the bellows 3 gradually shortens under the pressure of the frame surface. This shortening process causes the rubber tube 51 to bend and push the side plate 5, which slides outward. The protruding end of the side plate 5 is 5-10 cm away, and the vertical sidewall of the side plate 5 fits tightly against both sides of the frame, thereby preventing the frame from moving horizontally during clamping. This design not only improves the clamping stability of the clamp but also helps protect the frame from damage.

[0032] A slot is provided on one side of the fixing plate 11, and a connecting block is provided on one side of the upper clamping plate 2. The connecting block slides in the slot in the fixing plate 11. A screw 111 is threaded through the fixing plate 11 and the connecting block. A power source is fixedly connected to the top of the screw 111. The power source is preferably a micro motor. The output shaft of the motor is fixedly connected to the center of the screw 111. The motor drives the screw 111 to rotate, thereby driving the connecting block and the upper clamping plate 2 connected to it to move downward. As the upper clamping plate 2 gradually descends, it gradually approaches the lower clamping plate 1 and applies a clamping force to the frame.

[0033] As the upper clamp 2 descends, one end of the bellows 3 contacts the frame surface and gradually receives pressure. Due to the elasticity of the bellows 3, it gradually shortens under pressure, causing the rubber tube 51 connected to the closed end of the bellows 3 to bend towards the side plate 5. The bending of the rubber tube 51 pushes the side plate 5 to move horizontally outward. As the upper and lower clamps clamp the frame, the side plate 5 gradually pushes outward and makes close contact with the side of the frame through its extended end, thereby fixing the left and right position of the frame. At the same time, the upper and lower clamps fix the vertical position of the frame.

[0034] In order to provide stable support for the upper clamping plate 2 and the lower clamping plate 1 when using the clamp, slots 13 are provided at both ends on one side of the lower clamping plate 1. A connecting rod 4 is rotatably installed in the slot 13. The connecting rod 4 can be locked in the slot 13 and can rotate freely in it.

[0035] Both ends of the upper clamping plate 2 on the same side are provided with through holes 23. When the upper clamping plate 2 is driven to move downward by the motor, the connecting rod 4 is first rotated to make it vertical and one end of it is aligned with the through hole 23. As the upper clamping plate 2 gradually approaches, the connecting rod 4 gradually enters the through hole 23. Through the cooperation between the connecting rod 4 and the through hole 23, a stable and reliable support system is established between the upper clamping plate 2 and the lower clamping plate 1. This not only ensures the coordinated work of the two during the clamping process, but also improves the overall stability and load-bearing capacity of the clamp.

[0036] Several shock-absorbing rubber pads 12 are fixedly installed inside the lower clamping plate 1 to absorb and disperse the impact and vibration generated during the clamping process, thereby protecting the frame from damage and ensuring the clamping stability of the clamp.

[0037] Support legs 6 are provided at the four corners of the bottom edge of the lower clamping plate 1.

[0038] In practical use, the lower clamping plate 1 is placed under the frame, and the lower clamping plate 1 is made to fit against the bottom surface of the frame by adjusting the support leg 6. Then, the drive motor drives the screw 111 to rotate, thereby moving the upper clamping plate 2 downward. During the descent of the upper clamping plate 2, the corrugated tube 3 is subjected to pressure from the surface of the frame, and it will gradually shorten, causing the rubber tube 51 to bend towards the side plate 5, thereby pushing the side plate 5 to slide outward. The protruding end of the side plate 5 is in close contact with the side of the frame, fixing the left and right position of the frame. During this process, as the upper clamping plate 2 descends, one end of the connecting rod 4 gradually aligns with the through hole 23 and fits tightly with the through hole 23, providing stable support for the upper clamping plate 2.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
