DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0026] like Figures 1 to 4 As shown, the hydraulic lifting flatbed cart comprises a chassis and a top plate arranged in parallel, a lifting support device and a lifting drive device are installed between the chassis and the top plate, a loading platform 11 is slidably installed on the top plate, a walking wheel is installed at the bottom end of the platform 11, and a control handle 17 is installed on the platform 11;

[0027] The lifting support device includes a first support frame 21 and a second support frame 22 which are rotatably connected together to form a scissor-type structure, wherein the bottom end of the first support frame 21 is rotatably connected to the chassis, and the top end of the first support frame 21 is slidably connected to the top plate; the top end of the second support frame 22 is rotatably connected to the top plate, and the bottom end of the second support frame 22 is slidably connected to the chassis.

[0028] The bottom plate includes a lower frame 31, and a lower slide groove 32 is provided on the inner wall facing the lower frame 31. The bottom end of the second support frame 22 extends into the lower frame 31, and pulleys 33 cooperating with the lower slide grooves 32 on both sides are installed on both sides of the bottom end of the second support frame 22. The top plate includes an upper frame 41, and an upper slide groove 42 is provided on the inner wall facing the upper frame 41. The top end of the first support frame 21 extends into the upper frame 41, and pulleys 33 cooperating with the upper slide grooves 42 on both sides are installed on both sides of the top end of the first support frame 21. The pulley 33 includes a pulley 33 shaft connected to the second support frame 22 or the first support frame 21, one end of the pulley 33 shaft extends into the lower slide groove 32 or the upper slide groove 42 and is rotatably installed with a pulley 33 body, and a ball bearing is installed between the pulley 33 body and the pulley 33 shaft.

[0029] The walking wheels include a rear wheel 13 located at one end of the platform 11 and close to the control handle 17 and a front wheel 12 located at the other end of the platform 11. The rear wheel 13 is a universal wheel. Figure 5 As shown, the universal wheel includes a universal wheel shaft 14 rotatably connected to the platform 11, one end of the universal wheel shaft 14 is rotatably connected to the platform 11, and the other end is installed with a universal wheel seat 15, and a universal wheel body 16 is rotatably installed in the universal wheel seat 15.

[0030] The lifting drive device includes a hydraulic cylinder 51 for driving the scissor structure to move. The cylinder body of the hydraulic cylinder 51 is hinged to the top plate, and the outer end of the plunger rod of the hydraulic cylinder 51 is hinged to the first support frame 21 or the second support frame 22. The first support frame 21 is located on the inner side of the second support frame 22. A crossbeam 23 is installed on the first support frame 21, and the outer end of the plunger rod of the hydraulic cylinder 51 is hinged to the crossbeam 23.

[0031] A control box 52 that also serves as a counterweight is installed at one end of the top plate. A lifting controller (not shown in the figure) that controls the action of the hydraulic cylinder 51 is installed in the control box 52. A control button 53 connected to the lifting controller is provided on the control box 52. Handles 54 extending to both sides are installed on both sides of the control box 52. A counterweight block (not shown in the figure) is installed in the control box 52. When the table 11 slides forward, the counterweight block located at the rear end of the top plate can maintain balance and prevent the entire device from tipping forward. When the table 11 slides outward when loaded with goods, it is necessary to slide the table 11 onto a support platform, such as a car or the ground, and it cannot slide out in the air.

[0032] The two sides of the table plate 11 are provided with side panels 18 extending downward to the two sides of the top plate, and a slide rail 19 is installed between the side panel 18 and the top plate. Only a simple slide groove slide rail 19 is shown in the figure. In order to further optimize the product, the slide rail 19 is preferably a ball silent slide rail 19. The ball slide rail 19 is used to make pushing more labor-saving and smooth.

[0033] Flatbed carts are mostly used for loading and unloading cargo from small and medium-sized trucks, so the height of the platform 11 is designed to be consistent with the height of the conventional small and medium-sized truck compartments. For example, when the cargo in the compartment needs to be carried down, the hydraulic cylinder 51 controls the scissor structure to move the platform 11 to the height of the compartment floor, and then pushes the platform 11 outward so that the running wheels of the platform 11 cooperate with the compartment floor, pushes the cargo in the compartment onto the platform 11, and then slides the platform 11 back to its original position, and the hydraulic cylinder 51 controls the scissor structure to move the platform 11 to the bottom, the running wheels contact the ground, and then the flatbed cart is used to transport the cargo to the designated location. During the unloading process, there is no need to carry the cargo from a high place, which saves manpower and improves the handling efficiency.

[0034] If you want to move the goods to the vehicle, the process is basically the opposite of the above-mentioned unloading process. First, put the goods on the table 11 of the flatbed cart, and then push the cart to the opening at the rear of the car. The hydraulic cylinder 51 controls the scissor structure to lift the table 11 to the same height as the floor of the car, and then push the table 11 into the car to transport the goods. The table 11 retracts, falls, and resets; or after pushing the table 11 into the car, the hydraulic cylinder 51 controls the scissor structure to drive the chassis structure to rise. After the chassis and the top plate are combined into one, the chassis and the top plate are pushed to slide toward the table 11, and the flatbed cart and the goods are put into the car together, which is convenient for unloading the goods after arriving at the destination.

[0035] From the above description, it can be seen that the lifting type flatbed cart solves the technical problems in the prior art that the goods need to be moved up or down, which consumes a lot of manpower and has low work efficiency. In addition, the flatbed cart has a stable structure and flexible operation, and is suitable for small and medium-sized cargo transportation. It not only saves manpower, but also greatly improves the transportation efficiency.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
