Description

Technical Field

[0001] This utility model relates to the field of electric flatbed cart technology, specifically to a safety anti-collision device for electric flatbed carts. Background Technology

[0002] Electric flatbed carts, also known as electric flatbed trucks, electric level carts, trolleys, cross-pass carts, electric railcars, ground crawlers, etc., are a type of rail-mounted electric transport vehicle used in factories. First, it is a rail-type transport vehicle, requiring tracks to be laid on the ground. The tracks are generally I-beam shaped with surface contact. Second, it is an electrically driven vehicle, running automatically under the drive of a motor and reducer. Third, it is a flatbed cart with a flat platform and no cover. In special cases, it can be non-flat but without a cover. The vehicle body has no steering wheel, only forward and backward directions.

[0003] Electric flatbed carts are frequently used in the production process, especially in workshop environments with overlapping operations and dense personnel and equipment. They are usually equipped with anti-collision devices at the front of the electric flatbed carts. However, the protective structure of electric flatbed carts on the market is relatively simple, mainly relying on baffles as a means of protection. Their anti-collision performance is limited. Once an electric flatbed cart collides, the baffles alone cannot provide sufficient protection, which may lead to damage to surrounding equipment or injury to production personnel. Utility Model Content

[0004] The purpose of this utility model is to provide a safety anti-collision device for electric flatbed carts, which has the advantage of good protective effect and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety anti-collision device for an electric flatbed cart, comprising an electric flatbed cart body, with rollers fixedly connected to the four corners of the bottom of the electric flatbed cart body, housings embedded in both sides of the electric flatbed cart body, baffles provided on both sides of the electric flatbed cart body, a long rod fixedly connected to the inner cavity of the housing, two sleeve blocks slidably connected to the surface of the long rod, a first spring sleeved on the surface of the long rod, both ends of the first spring being fixedly connected to the sleeve blocks, a first connecting member fixedly connected to the surface of the sleeve blocks, an adjusting block rotatably connected to the inner cavity of the first connecting member, a second connecting member rotatably connected to one side of the adjusting block, and one side of the second connecting member being fixedly connected to the baffle.

[0006] Furthermore, as a preferred embodiment of this utility model, telescopic rods are fixedly connected to both sides of the inner cavity of the housing. The output end of the telescopic rod extends through to the outside of the housing and is fixedly connected to the baffle. A second spring is sleeved on the surface of the telescopic rod, and the two ends of the second spring are fixedly connected to the housing and the baffle, respectively.

[0007] Furthermore, as a preferred embodiment of this utility model, two sliding grooves are formed on one side of the inner cavity of the housing, and a slider is slidably connected to the inner cavity of the sliding groove, with one side of the slider being fixedly connected to the sleeve block.

[0008] Furthermore, as a preferred embodiment of this utility model, a protective pad is fixedly connected to one side of the baffle, and the protective pad has inclined surfaces on both sides.

[0009] Furthermore, as a preferred embodiment of this utility model, fixing blocks are fixedly connected to both sides of the housing, and a bolt is threadedly connected to one side of the fixing block. The housing and the electric flatbed vehicle body are detachably connected by bolts.

[0010] Beneficial effects: The technical solution of this application has the following technical effects: This utility model has the advantage of good protection effect. In actual use, the dual buffering effect of the first spring and the second spring can effectively absorb and disperse the impact force when the electric flatbed car body collides with the external object. The rotational connection of the adjusting block, the first connecting piece and the second connecting piece allows the baffle to have a certain range of motion when it is hit, thereby more effectively dispersing the impact force and reducing the damage caused by rigid collision. The telescopic rod not only serves as an additional buffer element, but also enhances the connection stability between the baffle and the shell, ensuring that the baffle can move smoothly during the collision, while maintaining the integrity of the overall structure and reducing the damage of the collision to the electric flatbed car body and the surrounding environment.

[0018] As attached Figure 1 To be continued Figure 3 As shown: This embodiment provides a safety anti-collision device for an electric flatbed cart, including an electric flatbed cart body 1. Rollers 3 are fixedly connected to the four corners of the bottom of the electric flatbed cart body 1. Housings 4 are embedded in both sides of the electric flatbed cart body 1. Baffles 5 are provided on both sides of the electric flatbed cart body 1. A long rod 6 is fixedly connected to the inner cavity of the housing 4. Two sleeve blocks 7 are slidably connected to the surface of the long rod 6. A first spring 8 is sleeved on the surface of the long rod 6. Both ends of the first spring 8 are fixedly connected to the sleeve blocks 7. A first connecting member 9 is fixedly connected to the surface of the sleeve blocks 7. An adjusting block 10 is rotatably connected to the inner cavity of the first connecting member 9. A second connecting member 11 is rotatably connected to one side of the adjusting block 10. One side of the second connecting member 11 is fixedly connected to the baffle 5.

[0019] Specifically, telescopic rods 12 are fixedly connected to both sides of the inner cavity of the housing 4. The output end of the telescopic rod 12 extends through to the outside of the housing 4 and is fixedly connected to the baffle 5. A second spring 13 is sleeved on the surface of the telescopic rod 12. The two ends of the second spring 13 are fixedly connected to the housing 4 and the baffle 5 respectively.

[0020] In this embodiment, the telescopic rod 12 and the second spring 13 work together to guide the baffle 5, so that the baffle 5 can move horizontally when it moves. At the same time, the telescopic rod 12 can provide effective support for the baffle 5, thereby improving the stability of the baffle 5 when it is placed.

[0021] Specifically, two sliding grooves 14 are provided on one side of the inner cavity of the housing 4. A slider 15 is slidably connected to the inner cavity of the sliding groove 14. One side of the slider 15 is fixedly connected to the sleeve block 7.

[0022] In this embodiment, the combined use of the slide groove 14 and the slider 15 serves to limit the movement of the sleeve block 7, thereby improving the stability of the sleeve block 7 during movement.

[0023] Specifically, a protective pad 16 is fixedly connected to one side of the baffle 5, and both sides of the protective pad 16 are provided with inclined surfaces.

[0024] In this embodiment, the protective pad 16 serves to protect the baffle 5, reducing the contact between the baffle 5 and external objects, thus making the baffle 5 less prone to wear.

[0025] Specifically, fixing blocks 2 are fixedly connected to both sides of the housing 4, and bolts are threadedly connected to one side of the fixing blocks 2. The housing 4 and the electric flatbed body 1 are detachably connected by bolts.

[0026] In this embodiment, the use of fixing block 2 and bolts together serves to fix the housing 4, while also making it easy for the user to disassemble and replace it.

[0027] The working principle and usage process of this utility model are as follows: When the electric flatbed cart body 1 collides with an external object, the protective pad 16 will first come into contact with the external object. The protective pad 16 drives the baffle 5 to move, the baffle 5 drives the second connecting member 11 to move, the second connecting member 11 drives one end of the adjusting block 10 to move, and when the adjusting block 10 moves, the other end will drive the first connecting member 9 to move. The first connecting member 9 drives the sleeve block 7 to slide on the surface of the long rod 6, so that the two sleeve blocks 7 move relative to each other. When the sleeve block 7 moves, it will drive the first spring 8 to compress. When the baffle 5 moves, it will drive the telescopic rod 12 and the second spring 13 to compress, thereby achieving the purpose of buffering, so that the electric flatbed cart body 1 is not easily damaged when it collides.

[0028] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
