Description

Technical Field

[0001] The invention relates to the technical field of hangers for hoisting prefabricated components, and in particular to a hanger for hoisting an assembled high-voltage protective shed and a use method thereof. Background Art

[0002] At present, there are many intersections between newly built railways and local high-voltage lines. In order to meet safety and use requirements, the construction method of relocating high-voltage lines is usually adopted. This method has some disadvantages: 1. The relocation procedures are cumbersome and the relocation period is long. It is necessary to coordinate with the provincial power supply department and coordinate with many large power users; 2. The power outage time is short and the relocation construction is difficult, especially the 500KVA high-voltage line generally only has a power outage once a year for one day. 3. It restricts the construction period. Due to the long relocation period, the project at the location of the high-voltage line is often the last railway through node control project.

[0003] In order to solve the difficulties in the construction of the intersection of railways and local high-voltage lines, a concrete assembled high-voltage line protection shed is set up above the newly built railway under the high-voltage line, which has no impact on the local high-voltage line, shortens the railway construction period, and ensures the safety of train operation. During the construction of the high-voltage line protection shed, a special lifting device is required to lift the prefabricated parts of the protection shed to the installation site to ensure the safety of the construction process.

[0004] When the existing lifting device is in use, the lifting device lacks a device to remind workers in the lifting area to stay away from the lifting area, so that during the operation of the lifting device, the construction workers below are not warned to stay away, increasing the safety risk of the lifting process. Secondly, when the existing lifting device is lifting prefabricated plate components, the lower sides of the two hooks lack a safety assurance structure, so that when the hooks encounter shaking of the plates and tilting from the hooks, the prefabricated plate components cannot be supported and protected, increasing the risk of the lifted components falling. Therefore, there is an urgent need for a lifting device for lifting assembled high-voltage protective sheds to solve the existing problems. Summary of the invention

[0005] The purpose of the present invention is to provide a hoisting device and a method for using an assembled high-voltage protective shed in order to solve the above-mentioned problem.

[0006] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0007] A lifting device for lifting an assembled high-voltage protective shed, comprising two symmetrically arranged lower cross beams and lifting rings installed at the centers of the upper side surfaces of the two lower cross beams, rotating cameras are installed at both ends of the lower cross beams, a loudspeaker is installed on one side of the lower portion of the lifting ring, dual-axis inclination sensors are installed on the upper side surfaces of the two lower cross beams, an intelligent pan-tilt platform is installed at the center of the lower side surfaces of the lifting rings, a wide-angle camera is installed on the intelligent pan-tilt platform, lower hanging hole plates are symmetrically arranged on the lower side surfaces of the lower cross beams, a cross bar is passed through the lower hanging hole plates, hooks are sleeved at both ends of the cross bar, an electric push rod is installed between the hooks, and connecting iron chains are arranged between the lower horizontal structures of the hooks.

[0008] Furthermore, shoulder pole beams are installed on the upper sides of both ends of the lower cross beam, upper ear plates are welded to the upper side surfaces of the shoulder pole beams, and the shoulder pole beams are welded to the lower cross beam.

[0009] Furthermore, side ear plates are symmetrically arranged on the outer side of the lifting ring, a tensioning steel cable is installed between the side ear plate and the upper ear plate, and a limiting block is welded on the lower side of the shoulder pole beam.

[0010] Furthermore, the limit block is arranged between the two lower cross beams, and the side ear plate is welded to the lifting ring.

[0011] Furthermore, both ends of the electric push rod are connected to the hook via bolts respectively, and the upper end of the hook is connected to the cross bar via a sliding bearing.

[0012] Furthermore, both ends of the cross bar are penetrated with limit pins, the speaker is connected to the hanging ring by bolts, and the rotating camera housing is connected to the lower cross beam by bolts.

[0013] Furthermore, the method comprises the following steps:

[0014] When hoisting the prefabricated components of a general protective shed, fix the upper end of the hoisting rope required for hoisting on the lower hoisting hole plate on the lower side of the lower crossbeam, and then hang the hook at the lower end of the hoisting rope and connect it to the prefabricated component to be hoisted;

[0015] The upper side of the hoist is connected to the hook of the lifting equipment through a lifting ring, and the lifting equipment lifts the prefabricated component;

[0016] The rotating camera and wide-angle camera can clearly capture the situation of the prefabricated components being hoisted, so that the hoisting operator can understand the movement of the hoisted prefabricated components in real time. The dual-axis inclination sensor can monitor the horizontal inclination of the lower beam and the shoulder beam in real time, and transmit the monitored signal to the hoisting equipment end. During the hoisting process, the speaker can broadcast voice in real time to remind the surrounding personnel to stay away from the hoisting area.

[0017] When lifting multi-layer stacked plate prefabricated parts, the crossbar and the hook are passed through the lower lifting hole plate so that the hook on each crossbar is installed on the inner side of the lower lifting hole plate, and the two ends of the electric push rod are connected and fixed to the hook. When the plate prefabricated part needs to be lifted, the electric push rod pushes the two hooks apart so that the hooks can span across the two sides of the plate prefabricated part. Then the electric push rod moves the two hooks toward each other so that the hooks clamp and fix the plate prefabricated part to ensure the stability of the lifting process. At the same time, the two hooks are connected together with a connecting chain so that the connecting chain can provide a guarantee for the stability of the hooks.

[0018] Furthermore, the position of the lower hanging hole plate is selected according to the size of the lifting component, and a reinforcing layer plate is welded at a right angle position on the lower side of the hook.

[0019] Furthermore, the hook angle is 85 degrees, and the dual-axis inclination sensor has a built-in battery module and a wireless transmission module.

[0020] Furthermore, the rotating camera and the wide-angle camera both have built-in battery modules.

[0021] The beneficial effects of the present invention are:

[0022] The present invention provides a dual-axis inclination sensor, a rotating camera, a wide-angle camera and a loudspeaker, so that the lifting operator can use the camera to monitor the situation of the lifting object in real time during the lifting process, and use the dual-axis inclination sensor to monitor the moving stability of the lifting equipment in real time. At the same time, the loudspeaker can give voice reminders to the construction workers below the lifting path, so that the construction workers can avoid it in time and reduce safety risks. The present invention provides a connecting chain, so that the two ends of the connecting chain are connected to the hooks on both sides through tongue-belt sliding hooks. When the prefabricated plate component lifted on the hook tilts from the hook due to shaking, the connecting chain can support the lower side of the prefabricated plate component and reduce the risk of the prefabricated plate component falling.
