Description

Technical Field

[0001] The utility model relates to the field of general maintenance tools, in particular to a climbing device for pipeline maintenance. Background Art

[0002] Continuous production processes such as thermal power and chemical industry often involve a large number of overhead pipelines. In order to ensure the safe operation of pipelines, regular inspections are required. The inspection work involves airtight inspection of connection positions, pipeline anti-rust process treatment, etc. In the prior art, related maintenance work is completed by workers standing on the pipeline with a safety rope tied. This working method is less safe, and many operations are inconvenient to perform due to the unstable standing of personnel. There are also ladder equipment specially used for pipeline suspension in the current commercial products, but there is a general situation where the pipe diameter is limited, which can easily cause the workers to stand unstable during work. For the above situation, there is currently a lack of corresponding solutions. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a pipeline maintenance climbing device with a simple structure, suitable for pipeline maintenance operations with multiple diameters, especially suitable for double rows or more of parallel pipelines, which enables workers to stand stably and is safe to use.

[0004] The equipment includes a ladder frame body, which is the assembly base of the equipment, including two side handrails arranged at intervals, and a stepping crossbar is evenly arranged in an array between the side handrails;

[0005] The side handrails of the ladder frame body are hingedly provided with a flap at the lower part; the flap is the standing base for the workers during construction, thereby providing a larger standing area for the workers;

[0006] An assembly base is arranged on the side handrail, a suspension hook body is passed through the assembly base, and the suspension hook body is in the form of a vertically bent curved rod. A fastener is also arranged on the assembly base.

[0007] The effect achieved in this way is that by maintaining the pipe diameter, the distance between the bending section of the suspension hook body and the side handrail can be flexibly adjusted so that it can be tightly clamped and hung on the pipe, and the flap is flipped down to form a large standing surface for personnel, thereby achieving the effect of suspension and stable operation of the equipment.

[0008] Furthermore, the fastener is a screw with a hand-tightened sleeve, that is, the suspension hook body is fixed in the form of a hard limit.

[0009] Furthermore, the side handrail is provided with a safety rope hanging ring, which is used to configure the equipment's own safety rope and the personnel's safety rope.

[0010] The beneficial effects of the utility model are as follows: the utility model solves the problem of unstable use of hanging ladder-type equipment in the prior art, realizes full locking of pipes of different diameters, and provides a wider standing surface for operators on this basis. It is particularly suitable for the hanging of double-row or multi-row parallel pipelines, and the assembly effect is more stable. In particular, the equipment has a simple structure and low cost, and has great safety promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0018] Reference Figure 1 , Figure 2 The utility model discloses a climbing device for pipeline maintenance, comprising a ladder frame body, which is the assembly base of the device, and comprises two side handrails 4 arranged at intervals, and a stepping crossbar is evenly arranged in an array between the side handrails 4;

[0019] On the side handrail 4 of the ladder frame body, a flap 6 is hingedly provided at the lower part thereof; the flap 6 is a standing base for workers during construction, thereby providing a larger standing area for the workers;

[0020] An assembly base 2 is provided on the side handrail 4, and a suspension hook body 1 is passed through the assembly base 2. The suspension hook body 1 is in the form of a vertically bent curved rod. A fastener is also provided on the assembly base.

[0021] The effect achieved in this way is that the distance between the bending section of the suspension hook body 1 and the side handrail 4 can be flexibly adjusted by maintaining the pipe diameter, so that it can be tightly clamped and hung on the pipe, and the flap 6 is flipped down to form a large area of ​​standing surface for personnel, thereby achieving the effect of suspension and stable operation of the equipment.

[0022] Furthermore, the fastener is a screw with a hand-tightened sleeve, that is, the suspension hook body 1 is fixed in the form of a hard limit.

[0023] Further, a safety rope hanging ring 3 is provided on the side handrail 4. The safety rope hanging ring 3 is used to configure the safety rope of the equipment itself and the safety rope of the personnel.

[0024] In the first embodiment, a flap ear plate is arranged on the flap 6, a ladder ear plate is arranged in front of the ladder frame body, the flap 6 and the ladder frame body are hingedly connected with the ladder frame ear plate through the flap ear plate, and the length of the flap 6 below the flap ear plate is greater than the length of the side handrail 4 at the lower part of the ladder frame ear plate;

[0025] The effect achieved by this is that the flap 6 is flipped down, with the bottom of the side armrest 4 as a limit, so that the flap 6 is folded to a certain angle to form a supporting table surface;

[0026] The bottom of the side handrail 4 is a slope, and the slope refers to a slope opened from the front of the side handrail 4 to the rear.

[0027] The effect achieved by this is shown in the attached figure of the specification Figure 2 As shown, the flap is arranged according to the center of gravity of a person standing, so that the flap 6 forms a substantially horizontal supporting table surface after the person stands.

[0028] Embodiment 2, a pull claw 5 is hingedly provided on the side of the ladder frame body, and the pull claw 5 includes a telescopic sleeve, and a fastening bolt is provided on the telescopic sleeve;
