Problems solved by technology

[0004] The main purpose of the present invention is to provide an adjustable hoist for hoisting formwork and its use method, to solve the situation that the length of the formwork dimension in the horizontal bridge direction does not change, and the length of the longitudinal bridge direction changes, so that the formwork size in a single direction changes. Changes, it is necessary to design corresponding spreaders for different sizes of templates, which increases the consumption of manpower and materials

Embodiment 1

[0036] Such as Figure 1~8 As shown, an adjustable spreader for hoisting formwork includes at least two main girders 1, adjacent main girders 1 are connected by a plurality of support beams 4 to form a spreader frame, and the spreader frame is also equipped with A plurality of lifting lugs 5, splints 2 are provided at both ends of the main beam 1 of the spreader frame, the splints 2 are slidably connected with the main beam 1, and the splints 2 are locked on the main beam 1 by a locking device. Such as figure 1 In the shown structure, the splint 2 slides on the main beam 1, and the multiple splints 2 clamp the formwork 10, and then use the locking device to lock the position of the formwork 10, so as to clamp the formwork 10 laterally.

[0037] In the preferred solution, a plurality of hydraulic cylinders 3 are also provided on the main beam 1, and the telescopic rod of a single hydraulic cylinder 3 is connected to the splint 2, and a crossbeam 6 is passed between adjacent su...

Embodiment 2

[0046] Further illustrate in conjunction with embodiment 1, as Figure 1-8 As shown, the two main beams 1 are assembled through two supporting beams 4, and the two supporting beams 4 are connected through a crossbeam 6, and a hand pump 7 is installed on the crossbeam 6.

[0047] Hydraulic cylinders 3 are installed at both ends of the two main girders 1, the hydraulic pipes of the hydraulic cylinders 3 communicate with the hydraulic ports of the hand pump 7, and the oil return ports of the hydraulic cylinders 3 communicate with the oil return ports of the hand pump 7.

[0048] A splint 2 is installed at the end of the main beam 1 , and the sliding body 205 of the splint 2 is connected with the telescopic rod of the hydraulic cylinder 3 .

[0049] Utilize the crane to connect with the lifting lug 5 of the sling through the steel cable, lift the whole sling, make the sling rise into the air, hang the whole sling on the formwork to be hung, and open the reversing valve 702 of the ...

Abstract

The invention provides an adjustable lifting appliance for lifting formworks and a using method thereof. The adjustable lifting appliance comprises at least two main beams, the adjacent main beams are connected through a plurality of supporting beams to form a lifting appliance frame, a plurality of lifting lugs are further arranged on the lifting appliance frame, clamping plates are arranged at the two ends of the main beams of the lifting appliance frame, the clamping plates are in sliding connection with the main beams, and the clamping plates are locked on the main beams through locking devices. The lifting appliance can be directly connected with the formworks, a sling is not needed, the distance between a lifting hook of lifting equipment and the lifted formworks is shortened, and the formworks can be lifted under the condition that the vertical space is limited; and meanwhile, the lifting appliance is provided with adjustable end part accessories and can adapt to formworks with different sizes, so that the utilization rate of the lifting appliance is improved, and manpower and material consumption are reduced.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to an adjustable hanger for hoisting formwork and a method for using the same. Background technique [0002] During the construction of cast-in-place concrete box girders, when the formwork is installed and removed with hoisting equipment and slings, due to the height limit of the hoisting equipment, there will be a situation where the hoisting work space is small. At the same time, the length of the formwork in the horizontal bridge direction remains unchanged and the length of the longitudinal bridge direction changes. In this way, the formwork size changes in a single direction. It is necessary to design corresponding specifications for different size formwork spreaders, which increases the labor and material costs. consume. [0003] Chinese patent CN208037831U is a template hoisting tool, which is used in conjunction with a steel wire rope, and includes a frame with...
