Abstract

This design lifting device is able to safely lift heavy objects and hooks of hydraulic crane at a high place such as a stack (heavy weight) of gas heater among natural gas supply facilities without requiring the worker to go up directly .

Description

{Heavy weight lifting device}

The present invention relates to a heavy lifting device capable of safely lifting a stack (heavy object) located at a high altitude by using a hydraulic crane when a gas heater is disassembled / maintained in a natural gas supply facility, The present invention relates to an apparatus for lifting a heavy object without raising it to a place where the object is lifted.

For example, gas facilities are operated at a high pressure at all times, but they are completely disassembled and serviced for 2 years / once or emergency maintenance, though they vary depending on the operating time.

Since it is heavy during decomposition and maintenance, it is disassembled / assembled using a hydraulic crane. Especially, there are facilities (machinery, electricity, instrument, etc.) .

Especially, in the case of the stack (STACK) installed at a height of 20M or more from the ground, when the lifting to the ground after disassembly, the worker directly buckets the shackle for towing and the sling belt to the lifting lugger (RUGGER) It has the hassle of installing it up and safety accident (risk of falling).

Korean Registered Patent No. 10-1329397 entitled "Device for decomposing a gas heater into a furnace," (Registered on Nov. 31, 2013)

It is an object of the present invention to provide a heavy lifting device for lifting a heavy object placed at a high altitude safely without having to go up to a position of a high altitude by a worker.

According to an aspect of the present invention, there is provided an apparatus for lifting a heavy object mounted on a crane by a crane hook,

A fixed bar fixed to an upper end of the heavy object and having a circumferential groove formed on an outer circumferential surface thereof,

A cap member having an upper portion formed with a hook to which the hook is coupled and an upper portion opened to be coupled to the fixing rod;

A fixing block fixed to a lower end of the cap member and having one side opened to surround the circumferential groove and to be seated on the weight;

A bracket fixed to an open side of the fixed block,

A pneumatic cylinder fixed to the bracket and having a coupling block which is coupled to or separated from the circumferential groove of the rod;

And a controller for controlling air supply to the pneumatic cylinder.

In addition, the present design lifting device has an illumination lamp and a camera attached to the fixed block,

And the controller displays a camera image on which the motion of the coupling block coupled to or detached from the peripheral groove is displayed.

And a proximity sensor is provided on the upper end of the heavy object or the fixed block so that the fixed block can be detected by being seated on the heavy object.

2 is a photograph showing a fixing rod fixed to the upper end of a heavy object,
Fig. 3 is a photograph of the main part of Fig. 1,
4 is a cross-sectional view showing a state where a cap member is coupled to a fixing rod,
5 is a schematic cross-sectional view of the main part of Fig.

The heavy lifting device of the present invention can safely load stacks (heavy objects) located at a high altitude in a gas heater disassembly / maintenance of a natural gas supply device by connecting hooks of a heavy crane and a hydraulic crane to a work site without going up to a high place So that it can be salvaged.

1 to 5 of the present embodiment, it is to be noted that the fixing rod 110 is fixed to the upper end of the heavy object 100 and has a circumferential groove 111 formed on the outer circumferential surface thereof, and a hook 201 The cap member 200 is fixed to a lower end of the cap member 200 and is opened at one side to surround the circumferential groove 111 and to be attached to the weighing rod 110. [ A bracket 220 fixed to the open side of the fixed block 210 and a bracket 220 fixed to the bracket 220. The bracket 220 is fixed to the rod 231, (Not shown) for controlling air supply of the pneumatic cylinder 230. The pneumatic cylinder 230 has a coupling block 232 to be coupled to or separated from the pneumatic cylinder 111. [

The fixed block 210 is provided with an illumination lamp 320 and a camera 310 and displays the camera image photographed when the coupling block 232 is coupled to or separated from the peripheral groove 111 A display unit (not shown) is provided in the controller.

The fixed block 210 or the bracket 220 may be provided with a proximity sensor 400 to detect that the fixed block 210 is seated on the heavy object 100.

Operation of the lifting device having the above-described configuration is as follows.

The hook of the crane is connected to the loop 201 of the cap member 200 on the ground and the cap member 200 is lifted by operating a crane to thereby couple the cap member 200 to the fixed rod 110. [

At this time, it is sensed that the cap member 200 is seated on the heavy object 100 by the sensing sensor 400, and after the sensing, the controller controls the coupling block 232 to move the fixed rod 110 to the peripheral groove 111.

An image of the coupling block 232 coupled to the circumferential groove 111 is displayed on the display unit of the cone crawler so that it can be confirmed by an operator on the ground, thereby enabling safe lifting.

The lifting device having the above-described structure can connect the hooks of the heavy-duty crane and the heavy-duty crane without lifting the worker directly to a high place such as the stack (heavy load) of the gas heater among the natural gas supply equipment, .
