Problems solved by technology

At present, in the field of lifting, fully enclosed guardrails and grid guardrails are mainly used. The quality of the fully enclosed guardrails is relatively heavy, which can prevent things on the lifting platform from falling from the lifting platform and cause accidents; the grid guardrail is lighter. , but the maintenance tools on the lifting platform are easy to fall from the surrounding area, which will lead to low work efficiency, delay the speed of repair, affect the heating safety of the unit, and seriously cause safety accidents

Embodiment 1

[0031] refer to Figure 1 to Figure 3 , which is the first embodiment of the present invention, which provides a new type of lifting equipment for inspecting water-cooled wall tubes inside a boiler, including a lifting assembly 100 and a rotating assembly 200. The lifting assembly 100 includes a lifting platform 101, a grid guardrail 102 and a lifting device The plate 103, the grid guardrail 102 is fixed on the top of the lifting platform 101, the lifting plate 103 is arranged in the grid guardrail 102; the rotating assembly 200, the rotating wheel 201 and the rotating member 202, the rotating member 202 is fixed on the top of the grid guardrail 102, the rotating member 202 passes through the rotating wheel 201.

[0032] Preferably, the grid guardrail 102 is lighter in quality than the guardrails that are fully enclosed around it. The use of the lift plate 103 can solve the problem that the maintenance tool has fallen from the periphery of the lift table 101; the addition of t...

Embodiment 2

[0036] refer to Figure 1 to Figure 6 , is the second embodiment of the present invention, which is different from the previous embodiment in that: the grid guardrail 102 includes a first column 102a, a second column 102b and a third column 102c, and the first column 102a is fixed on the lifting platform At the top of 101, the first column 102a and the third column 102c are connected by the second column 102b.

[0037] The lift plate 103 reciprocates between the first column 102a and the second column 102b.

[0038] Preferably, the rotating assembly 200 is arranged on the top of the first column 102c, and the rotating member 202 can be rotated, so that the rotating wheel 201 can retract and pay off the pull rope, and drive the lifting plate to rise or fall, and the lifting plate 103 is pulled by the pull rope. Back and forth between the first column 102a and the second column 102b.

[0039] A connecting member 203 is provided on the outside of the rotating wheel 201. The con...

Embodiment 3

[0047] refer to Figure 1 to Figure 9 , is the third embodiment of the present invention, which is different from the previous two embodiments in that the telescopic member 205 passes through the rotating member 202 and the rotating disk 204 .

[0048] Preferably, the telescopic member 205 passes through the rotating member 202 and the rotating disk 204 first, and locks and unlocks the rotating disk 204 .

[0049] The telescopic member 205 includes a moving rod 205a, a connecting sleeve 205b and a push rod 205c. The moving rod 205a passes through the rotating member 202 and the rotating disk 204. The connecting sleeve 205b is fixedly arranged on the other side of the rotating disk 204, and the sliding groove 204c is opened at the The other side of the rotating disk 204, one side of the sliding block 204d is arranged in the sliding groove 204c, and one end of the push rod 205c is rotatably connected with the moving rod 205a.

[0050] Further, the connecting sleeve 205b is fixe...

Abstract

The invention discloses a novel lifting device for inspection of a water wall tube in a boiler, the novel lifting device comprises a lifting assembly and a rotating assembly, the lifting assembly comprises a lifting table, a grid guardrail and a lifting plate, the grid guardrail is fixed at the top of the lifting table, and the lifting plate is arranged in the grid guardrail; the rotating assembly, the rotating wheel and the rotating piece are fixed to the top end of the grid guardrail, and the rotating piece penetrates through the rotating wheel. The grid guardrail is combined with the lifting plate, so that the problem of heavy weight of the guardrail with totally closed periphery can be solved, maintenance tools on the lifting platform cannot fall from the periphery, and safety accidents are avoided; the lifting of the lifting plate can be better controlled through the rotating assembly, operation is easy, and use is easy.

Description

technical field [0001] The invention relates to the technical field of lifting equipment, in particular to a novel lifting equipment for inspecting water-cooled wall tubes inside a boiler. Background technique [0002] In power plants, boiler water-cooled wall tube maintenance, anti-wear and explosion-proof inspections, and emergency repairs are important maintenance methods for unit heating safety, and lifting equipment is particularly important. At present, the fully enclosed guardrail and grid guardrail are mainly used in the lifting field. The fully enclosed guardrail is heavier and can prevent the things on the lifting platform from falling from the lifting platform and causing accidents; the grid guardrail is lighter. , but the maintenance tools on the lifting platform are easy to fall from the surrounding area, which will lead to low work efficiency, delay the speed of emergency repair, affect the heating safety of the unit, and cause serious safety accidents.
