Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Example 1:

[0021] This embodiment provides a safety lifting platform for a truck cargo compartment, specifically as follows: Figure 1 , Figure 2 As shown, it includes: an operating platform 10, a lifting platform 20, a transmission device 30, and a truck tarpaulin unveiling area 70;

[0022] The operating platform 10 is set up on one side of the truck tarpaulin area 70;

[0023] The operating platform 10 is connected to the lifting platform 20. The lifting platform 20 is located on the side of the operating platform 10 near the truck tarpaulin area 70. The height of the lifting platform 20 is the same as the height of the truck tarpaulin area 70. The lifting platform 20 is equipped with a foldable handrail 60, which can be folded as the lifting platform 20 rotates. The foldable handrail 60 is used to protect the safety of personnel when walking on the lifting platform 20.

[0024] The operating platform 10 is equipped with a transmission device 30, which is connected to the lifting platform 20. The transmission device 30 is used to control the rotation of the lifting platform 20 on one side of the operating platform 10. The rotation angle of the lifting platform 20 on the operating platform 10 is 0-80°. When the lifting platform 20 is in use, it is relatively parallel to the ground of the truck tarpaulin area 70. At this time, the rotation angle of the lifting platform 20 is zero degrees. This makes it convenient for the lifting platform 20 to adapt to trucks of different heights. At the same time, the lifting platform 20 can also be retracted to one side of the operating platform 10, which facilitates the entry and exit of trucks in the truck tarpaulin area 70.

[0025] Example 2:

[0026] This embodiment further expands the structure of the operating platform 10 based on embodiment 1, specifically as follows: Figure 1 , Figure 2As shown, the operating platform 10 is composed of a steel structure. The operating platform 10 is mainly erected above the ground by steel columns. The distance between the operating platform 10 and the ground is determined by the height of the cargo box of the truck at the truck tarpaulin area 70. The operating platform 10 is equipped with a platform staircase 40, which is located between the operating platform 10 and the ground to facilitate personnel movement up and down. The operating platform 10 is equipped with a fixed handrail 50 to prevent personnel from falling from a height. The fixed handrail 50 has an access opening on one side of the lifting platform 20 to facilitate operators to walk onto the lifting platform 20. When the lifting platform 20 is retracted onto the operating platform 10, the lifting platform 20 itself closes the access opening of the fixed handrail 50 to prevent personnel from falling from the access opening.

[0027] Example 3:

[0028] This embodiment further expands the structure of the transmission device 30 based on Embodiment 1, specifically as follows: Figures 1 to 3 As shown, the transmission device 30 includes a worm gear reducer 301, a connecting seat 302, a steering pulley 303, and a connecting steel cable 304. The connecting seat 302 is fixedly connected to the operating platform 10. An input wheel is provided on the connecting seat 302. The output shaft of the connecting seat 302 is fixedly connected to the worm gear reducer 301. The worm gear reducer 301 is rotatably connected to the operating platform 10. Multiple steering pulleys 303 are provided on the operating platform 101 to change the sliding direction of the connecting steel cable 304. One end of the connecting steel cable 304 is provided on the worm gear reducer 301, and the other end of the connecting steel cable 304 is provided on the lifting platform 20 to allow the lifting platform 20 to rotate. The connecting steel cable 304 is in contact with multiple steering pulleys 303.

[0029] After the user rotates the input wheel on the connecting seat 302, the worm gear reducer 301 will rotate after changing the transmission ratio, and then drive the lifting platform 20 to rotate on the operating platform 10 through the connecting steel cable 304.

[0030] Working principle: When there are no vehicles operating, this device is in the following state: Figure 2 As shown, the lifting platform 20 rotates to an angle of 80° with the ground. At this time, the lifting platform 20 is in a retracted state, which facilitates the entry and exit of vehicles. In this state, the lifting platform 20 closes the passage on the fixed handrail 50 to prevent people from falling from the operating platform 10.

[0031] When a truck needs its tarpaulin removed, the operator ascends to the operating platform 10 via the platform stairs 40. The operator then rotates the input wheel of the worm gear reducer 301 (which can also be replaced by an electric motor). The worm gear reducer 301 then drives the connecting seat 302 to rotate, which in turn drives the lifting platform 20 to rotate on the operating platform 10 via the connecting steel cable 304. At this point, one end of the lifting platform 20 is brought close to the top of the truck, so the connecting steel cable 304 is released. This allows the lifting platform 20 to rotate until it is parallel to the ground in the truck's tarpaulin removal area 70. The operator can then enter the lifting platform 20 through the access opening on the fixed handrail 50. The foldable handrails 60 on both sides of the lifting platform 20 ensure the operator's safety at height. This allows the operator to smoothly walk to the top of the truck to perform the work, improving work efficiency, reducing the operator's labor intensity, and avoiding the risk of falling while climbing to the top of the truck.

[0032] After the operation is completed, the operator can reverse the input wheel of the worm gear reducer 301. This will allow the connecting seat 302 to drive the lifting platform 20 to rotate via the connecting steel cable 304. At this time, one end of the lifting platform 20 is away from the top of the truck, so the connecting steel cable 304 is retracted. This will allow the lifting platform 20 to retract to its initial state. At this time, the lifting platform 20 will close the passage on the fixed handrail 50, preventing people from falling and providing a safety protection function.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
