[0002] The factory workshop will involve the carrying of production materials in many places, and most of the carrying is by people, and when the carrying object is heavy, the carrying strength is very large. Especially for the occasion with large material demand and high carrying frequency, the staff often bend down to carry, which is very unfavorable to the work intensity and the safety and health protection of the staff.

[0003] A common problem in production is that when the baskets need to be stacked on the carrying trolley for circulation, for example, three baskets are stacked from bottom to top, since the support base of the carrying trolley is fixed in height, the workers need to bend down greatly when placing the lower two baskets, which is labor-intensive for a long time, resulting in damage to the workers' waist. UTILITY MODEL CONTENT

[0004] In view of the deficiencies in the prior art, the main purpose of the utility model is to provide a labor-saving carrying trolley which facilitates the placement of the basket and reduces the bending action.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a labor-saving carrying trolley, comprising a trolley body with universal casters, a support frame is arranged on the trolley body, a fixed pulley mechanism is arranged on the support frame, a damping mechanism is connected to one side of the fixed pulley mechanism through a rope, and a lifting platform mechanism is connected to the other side of the fixed pulley mechanism through a rope, a support base for placing the baskets is arranged on the lifting platform mechanism, the damping mechanism drives the support base to rise to a position where the worker does not need to bend down when placing the first basket, and the damping mechanism provides a pulling force that can support the weight of one or several baskets.

[0006] Preferably, the fixed pulley mechanism comprises one or more pulley blocks, each pulley block comprises a support rod fixedly arranged on the support frame, one or more fixed pulleys are arranged on the support rod, and a rope is wound around the fixed pulleys.

[0007] Preferably, the damping mechanism is arranged in one-to-one correspondence with the pulley blocks, the bottom of the damping mechanism is fixedly arranged on the trolley body, and the top of the damping mechanism is connected to the fixed pulley mechanism through a rope.

[0008] Preferably, the damping mechanism is one or more springs or elastic bands.

[0009] Preferably, the lifting platform mechanism comprises a sliding rod fixedly arranged on the trolley body, and the support base is fixedly connected with a linear rolling sleeve arranged on the sliding rod.

[0010] Preferably, the bottom of the support base is fixedly provided with omnidirectional casters.

[0011] Preferably, the support frame is provided with a trolley handle.

[0012] This invention has the following advantages over existing technologies: it employs a fixed pulley combined with a damping mechanism to achieve the vertical lifting of the support base. Through the combination of the tension of the damping structure (such as a spring) and the fixed pulley, the placement height of the material box is automatically adjusted, ensuring that the material box is always placed at the optimal working height, allowing the operator to work without bending over. Different damping systems (such as springs) can be designed according to the weight of the material box to achieve adjustment for material boxes of different weights. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figure 1 As shown, a labor-saving handling trolley includes a trolley body 1 with swivel casters 2. A support frame 3 is provided on the trolley body 1, and a fixed pulley mechanism 4 is provided on the support frame 3. One side of the fixed pulley mechanism 4 is connected to a damping mechanism 5 via a rope 43, and the other side is connected to a lifting platform mechanism 6 via a rope 43. A support base 61 for placing material baskets is provided on the lifting platform mechanism 6. The damping mechanism 5 drives the support base 61 to rise to a position where the worker does not need to bend over when placing the first material basket via the rope 43, and the pulling force provided by the damping mechanism 5 can support the weight of one or more material baskets.

[0017] Preferably, the fixed pulley mechanism 4 includes one or more pulley groups, each pulley group including a support rod 41 fixedly mounted on the support frame 3, and one or more fixed pulleys 42 and a rope 43 wound around the fixed pulleys 42 are provided on the support rod 41.

[0018] Preferably, the damping mechanism 5 is provided in a one-to-one correspondence with the pulley group, the bottom of the damping mechanism 5 is fixedly mounted on the trolley body 1, and the top of the damping mechanism 5 is connected to the fixed pulley mechanism 4 through the rope 43.

[0024] Refer to the accompanying Figure 1 Taking the example that three material baskets need to be placed on the support base 61, the action process is as follows:

[0025] Initial state: the universal caster 2 fixes the trolley body 1, the support base 61 is not placed with the material frame, the damping mechanism 5 pulls the upper surface of the support base 61 to the best working height point through the rope 43, and the position of the best working height point is the position that does not need to bend down or lift high when placing the material basket.

[0026] The worker places the A frame on the support base 61, the support base 61 descends after the weight increases, and the damping mechanism 5 is stressed, and the upper surface of the A frame after the descending height is ensured to be at the best working height point through the rope 43; the worker places the B frame on the support base 61, the support base continues to descend after the weight increases, and the damping mechanism 5 is stressed, and the upper surface of the B frame after the descending height is ensured to be at the best working height point through the rope 43; the worker places the C frame on the upper surface of the B frame to complete the stacking, releases the brake, and pushes the trolley handle 7 to perform the material turnover.
