Description

Technical Field

[0001] The utility model relates to the field of high-altitude hoisting devices, in particular to a hoisting device for a high-altitude fixed track. Background Art

[0002] The existing methods of high-altitude lifting mainly include manual lifting method, simple lifting device method and crane lifting method. The manual lifting method usually involves workers standing at a high place and using ropes to stretch heavy objects to a high place by manpower. This traditional method is simple to operate, but has high labor intensity and high safety risks. It can only achieve simple up and down movements and is suitable for intermittent work with small loads, short time and low heights. The simple lifting device method is an improved method of the manual lifting method. It uses a simple lifting device to replace part of the manual operation, but it can also only achieve simple up and down movements. The crane lifting method uses a mechanical power device for lifting, which can achieve a higher lifting height, lift heavier goods, and has a larger lifting movement and range. However, the lifted goods shake severely in the air, have poor stability, and are difficult to position in the air.

[0003] At present, in the maintenance construction of bridge pier caps, manual lifting is usually adopted to hang and unfold the curing film roll in the air. There is an urgent need for a high-altitude fixed track lifting device with high efficiency and strong adaptability.

[0010] A further technical solution is that, in the above-mentioned hoisting device for the high-altitude fixed track, the track is a C-shaped steel structure.

[0011] A further technical solution is that in the hoisting device for the high-altitude fixed track, end surface limit devices are installed at both ends of the track.

[0012] A further technical solution is that, in the above-mentioned hoisting device for the high-altitude fixed rail, the end face limiting device is a longitudinal through bolt sleeved in the longitudinal through hole of the rail to limit the position.

[0013] A further technical solution is that, in the above-mentioned hoisting device for the high-altitude fixed track, limited position fixing devices are installed at both ends of the track at a distance equal to that of the pulley.

[0014] A further technical solution is that, in the above-mentioned hoisting device for a high-altitude fixed track, the pulley comprises four pulleys, two on the left and two on the right, and the pulleys are nested in the track of the track.
