DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1~Figure 2As shown, this embodiment proposes a lifting device for casting bridge ground sheet formwork, including a connecting tube 1 and a hanging rod 2, the hanging rod 2 is movably set on the connecting tube 1; a bracket 3, having a fixed part 301 and a supporting part 302, the supporting part 302 is hingedly set on the connecting tube 1, the fixed part 301 is in contact with the ground, and after the bracket 3 rotates, the fixed part 301 approaches or moves away from the connecting tube 1; a positioning member 4, one end of the positioning member 4 is movably set on the connecting tube 1, and the other end of the positioning member 4 is hingedly set on the bracket 3.

[0026] In this embodiment, the positioning member 4 includes a positioning portion 401 and a connecting rod 402. The positioning portion 401 is movably set on the connecting tube 1. One end of the connecting rod 402 is hingedly set on the positioning portion, and the other end is sleeved on the bracket 3. The bracket 3 is an H-shaped steel frame. One end of the connecting rod 402 is sleeved on the crossbeam 303 in the middle of the H-shaped steel frame. When in use: the supporting portion 302 abuts against the ground, and the connecting tube 1 is supported by the fixing portion 301 to fix the position of the positioning member 4. The fixing method can be clamping fixation or bolt tightening, so as to fix the angle between the fixing portion 301 and the supporting portion 302, limit the relative movement of the fixing portion 301 and the supporting portion 302, so that the bracket 3 cooperates with the positioning member 4 to form a stable fulcrum, and then move the suspension rod 2 out of the connecting tube 1 and move it to a suitable length for lifting materials. The position of the suspension rod 2 is fixed by bolts or clamping to lift the materials.

[0027] When in the storage state, loosen the tightening bolt of the positioning member 4 or cancel the clamping of the positioning member 4 so that the positioning member 4 can move on the connecting tube 1, rotate the supporting part 302 toward the positioning member 4 to make it close to the fixing part 301 of the bracket 3, so that the bracket 3 can be retracted. After the bracket 3 is retracted, cancel the bolt tightening or the positioning hole clamping of the suspension rod 2, and push the suspension rod 2 extending outside the connecting tube 1 into the connecting tube 1 to complete the retraction of the suspension rod 2. The retraction of the lifting device can be achieved in the height and length directions, which effectively reduces the storage space.

[0028] Furthermore, the support portion 302 is slidably disposed on the connecting tube 1 parallel to the axial direction of the connecting tube 1 .

[0029] In this embodiment, when the lifting device is used to lift materials, different materials have different weights. In order to improve the adaptability of the lifting process, the sliding of the support part 302 is designed.

[0030] When in use, the support part 302 can be first slid to move it to a suitable position, and then tightened by bolting to make it a lifting fulcrum. When adjustment is needed during use, the bolts can be first loosened and then adjusted according to the weight of the material. When the support part 302 is away from the lifting part of the boom 2, the force arm between the material and the support part 302 increases, and more manpower is required to lift it. When the support part 302 is close to the lifting part of the boom 2, the force arm between the material and the support part 302 decreases, and relatively less manpower is required to lift it. It can be adjusted according to the habits of the staff and the actual weight of the material, thereby improving adaptability.

[0031] Furthermore, the fixing portion 301 has two rollers 5 .

[0032] In this embodiment, when in use: the staff lifts the material and then pushes the lifting device, and under the action of the roller 5, the material can be lifted to the corresponding position.

[0033] When storing, the two rollers 5 follow the support part 302 to rotate close to the connecting tube 1. At this time, by pushing the lifting device, the retracted lifting device can be pushed to the designated storage area. When it is needed, the retracted lifting device can be pushed to the working area and then extended, which improves the convenience during the movement.

[0034] Furthermore, it also includes: a push rod 6 movably arranged on the connecting tube 1 , and a push handle 7 is arranged at one end of the push rod 6 located outside the connecting tube 1 .

[0035] In this embodiment, when in use, the lifting rod 2 is located on one side of the bracket 3. The object needs to be lifted, and the position is high and difficult to adjust. Therefore, a retractable push rod 6 is designed. By extending and retracting the push rod 6, the distance between the push handle 7 and the support part 302 can be adjusted. Therefore, when the distance from the material to the support part 302 is constant, the force arm between the push handle 7 and the support part 302 is increased or decreased, and the force required for lifting is adjusted. After the adjustment is completed, the position is fixed using bolts or a clamping structure.

[0036] When pushing or storing is required, the push handle 7 can better push the lifting device to move.

[0037] Furthermore, it also includes: a hanging member 8, which is arranged on the connecting tube 1, and the hanging member 8 is used to hang the counterweight, and the hanging member 8 is located between the push rod 6 and the positioning member 4.

[0038] In this embodiment, during the construction process, the weight of the materials is often too heavy to be lifted by manpower, so a hanging member 8 is designed. A certain counterweight can be hung on the hanging member 8 through a rope or other tool, which can help manpower to press one side of the push rod 6 downward to form a balance with the lifting end, thereby lifting the material.

[0039] At the same time, since the counterweight often has a certain weight, in order to avoid safety problems such as the counterweight crushing the workers' feet when the workers push the lifting device, the hanging part 8 is designed to be a certain distance in front of the push rod 6, so that the workers can observe the hanging and position of the counterweight simultaneously.

[0040] Furthermore, the hanging member 8 is movably arranged on the connecting tube 1 , and the hanging member 8 has a hanging portion 801 and a moving portion 802 , the hanging portion 801 is hingedly arranged on the moving portion 802 , and the moving portion 802 is movably arranged on the connecting tube 1 .

[0041] In this embodiment, it takes a certain amount of manpower to hang the counterweight on the hanging part 8. Therefore, in order to improve the usability of a single counterweight in multiple scenarios, the movable part 802 is movably set on the connecting tube 1. After the movement, the hanging part 8 can be close to or away from the lifting device, thereby changing the force arm between the counterweight and the fulcrum. When the counterweight is at the farthest distance from the support part 302, the assistance provided is the greatest.

[0042] Furthermore, it also includes: a hanging rope hook, which is arranged on the push handle 7 and has a rope release opening 10.

[0043] In this embodiment, in order to improve the control effect of the staff on the lifting device, a hanging rope hook 9 is designed. When lifting heavier materials, the rope can be passed through the hanging rope hook 9 and tied to the staff, so that the material can be lifted more conveniently through the push handle 7. When the material is too heavy or when placing the material, the hanging rope hook 9 rises upward, and the rope is separated from the hanging rope hook 9, ensuring the safety of the staff.

[0044] Furthermore, it also includes: a stabilizing frame 11, which is arranged on the connecting tube 1.

[0045] In this embodiment, a stabilizing frame 11 is provided on the connecting tube 1 , and the stabilizing frame 11 can improve the stability and strength of the connecting tube 1 .

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
