An automatic lifting machine for water conservancy projects with increased resistance and anti-detachment

Abstract

The invention discloses an automatic lifting machine with resistance enhancement and anti-falling functions for a water conservancy project. The automatic lifting machine structurally comprises a base, a supporting rod, a main rod, a movable hinge, a coiling device, an adjusting frame, a cable and an anti-falling device. The automatic lifting machine with the resistance enhancement and anti-falling functions for the water conservancy project has the beneficial effects that the cable protection is realized through an anti-friction ring, the breaking phenomenon of the cable is avoided under theshaking of the over-transition and the friction effect of an object, the interaction effect between a resistance increasing plate and a gas through plate is utilized, the fastening effect of the device and the object contact surface is increased, the occurred phenomenon of loss of balance caused by falling or local slippage and then unnecessary high-altitude falling object damage is caused is prevented, meanwhile, through convex particles which are made of wet rubber materials, the cementation is realized when a plastic pipeline is grabbed and the abrasion is prevented from being generated onthe grabbing surface of the plastic pipeline, and the downward strong airflow blowing is achieved under the action of segmented torsion spring rings, so that the grabbed object has a downward air pressure stabilizing effect so as to realize the balance effect on the central part of the grabbed object.

Description

technical field [0001] The invention relates to the field of water conservancy engineering equipment, more precisely, it is an automatic lifting machine for water conservancy engineering with increased resistance and anti-detachment. Background technique [0002] Facing a series of major problems such as rapid population growth, insufficient available water resources, and urban water supply shortages, the construction of water conservancy projects plays an important role in the development and utilization of water resources, which solves people's water problems. . In the construction of water conservancy projects, because the project is relatively large and the required pipelines are several times larger than the normal pipelines, it needs to be moved and installed by machines. Usually, lifting machinery is used to move the pipelines. Solve the transition output of manpower. [0003] However, when the traditional lifting equipment lifts the pipeline, it directly uses cable...

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an automatic lifting machine for water conservancy projects with increased resistance and anti-detachment, so as to solve the problem that the traditional lifting equipment in the prior art is directly passing through when the pipeline is lifted. The bundled lifting and moving of cables and cables between the pipes leads to local slippage during the transfer process. Because the pipes are lifted and moved in an outdoor and relatively open position, the air flow is relatively large and in the There is movement resistance during the movement, which will cause the pipe to shake greatly, causing wear on the surface of the pipe. At the same time, under the action of the large shake, the contact surface between the cable and the pipe will produce friction. And wear the cable to cause it to be cut, resulting in the defect of falling objects from high altitude
