Problems solved by technology

[0003] The lifting speed of the current hoisting device is often determined by the driving equipment. In order to improve work efficiency, high-power driving equipment is often required, and the cost is relatively high. However, the general driving equipment has a fixed lifting speed, which is not practical enough and needs to be optimized.

Embodiment 1

[0024] Such as Figure 1-4 The lifting device for bridge construction shown includes a base 1, the upper end of the base 1 is fixedly equipped with a fixed column 4 and a rotating motor 16, the upper end of the fixed column 4 is fixedly installed with a fixed plate 8, and the bottom side of the fixed plate 8 is A plurality of first pulleys 9 are installed, a suspension rope 11 is installed above the first pulley 9, a lifting mechanism 10 is installed above the suspension rope 11, and the lifting mechanism 10 is arranged in the fixed column 24. The rotating motor The output end of 16 is fixedly installed with rotating shaft 14, and described rotating shaft 14 is sheathed with the fixed plate 15 that is fixedly connected with it, and one end of described suspension rope 11 is connected with fixed plate 15, and the other end is connected with hanging basket 13, when rotating motor 16 rotates Rotate with the fixed plate 15 during rotation, thereby shrink or stretch with the sling ...

Embodiment 2

[0028] This embodiment is further optimized on the basis of embodiment 1, as Figure 5-7 As shown, the first bevel gear 2 is rotatably connected to the rotating shaft 14, and the end of the rotating shaft 14 away from the rotating motor 16 is equipped with a clutch mechanism for controlling the first bevel gear 2, that is, the first bevel gear is adjusted by setting the clutch mechanism. Whether the shape gear 2 is fixedly connected to the rotating shaft 14 is controlled, so that the lifting speed is controlled according to the usage situation, which is more practical and efficient.

[0029] Further, the clutch mechanism includes a telescopic motor 29, the telescopic motor 29 is fixedly installed on the rotating shaft 14, the output end of the telescopic motor 29 is fixedly installed with a sleeve 28, and the sleeve 28 is sleeved on the outside of the rotating shaft 14 And it is slidingly connected with it. For the convenience of the installation of the clutch mechanism, a lim...

Abstract

The invention relates to a lifting device for bridge construction, and belongs to the technical field of bridge equipment. The lifting device comprises a base, wherein a fixing column and a rotating motor are mounted at the upper end of the base; a fixing plate is mounted at the upper end of the fixing column; a plurality of first pulleys are mounted on one side of the bottom of the fixing plate;a lifting rope is mounted above the first pulleys; a lifting mechanism is mounted above the lifting rope; a rotating shaft is mounted at the output end of the rotating motor; a fixing disc is mountedoutside the rotating shaft; one end of the lifting rope is connected with the fixing disc, and the other end of the lifting rope is connected with a lifting basket; and one end of the rotating shaft penetrates through the fixing column and is connected with the lifting mechanism. According to the lifting device, the lifting mechanism is arranged, the distance between a second pulley and the firstpulleys is synchronously adjusted in the process of contracting and extending the lifting rope, so that the lifting speed is adjusted, and the working efficiency is improved; and the working states ofa clutch mechanism and the lifting mechanism are controlled, so that the lifting speed is controlled according to the use condition, the selectivity is high, and the lifting device is more practicaland convenient.

Description

technical field [0001] The invention relates to the technical field of bridge equipment, in particular to a lifting device for bridge construction. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. During the construction of the bridge, it is necessary to send various materials and parts used to the construction site, and as the construction height changes, it is often necessary to use the corresponding lifting device. [0003] The lifting speed of the current hoisting device is often determined by the driving equipment. In order to improve work efficiency, high-power driving equipment is often required, and the cost is high. However, the g...
