Description

Safety rope hanging device for climbing operation

Technical Field

The utility model relates to a high-altitude operation safety protection device, in particular to a safety rope hanging device for climbing operation, and belongs to the technical field of safety facilities.

Background

Products such as large pressure vessels are commonly required to be operated at heights of 2 meters or more during the manufacturing process. According to the safety management program of high-altitude operation and the safety operation regulation of high-altitude operation, reliable safety protection is required during operation, and the safety belt is worn and hung at a high position for low use. However, due to the limitation of site resource conditions, it is often difficult to conveniently take effective protective measures for climbing operations, and potential safety hazards are easy to exist. Especially when the job site needs to be constantly moved and changed.

Disclosure of Invention

The utility model aims to: to the problem that above-mentioned exists, provide one kind can be by the suitability of operation personnel regulation and control strong, use convenient operation safety rope of ascending a height and rely on the device to for the operation personnel of ascending a height provide reliable safety guarantee, and the device does not occupy work piece handling space, helps improving the operating efficiency.

In order to achieve the purpose, the utility model adopts the following basic technical scheme: the safety cable hanging device comprises an upper sleeve and a lower sleeve which are fixed on a stand column, wherein the upper sleeve and the lower sleeve respectively extend out of a horizontal upper connecting seat and a horizontal lower connecting seat;

the sleeve is fixedly connected with a porous pin seat with positioning holes distributed at intervals in the circumferential direction; the lower sleeve is provided with a remote control telescopic positioning pin;

when the positioning pin is lifted and inserted into the positioning hole of the porous pin base, the sleeve is positioned angularly; the sleeve has angular freedom when the locating pin is retracted out of the locating hole of the porous pin holder.

Therefore, the utility model not only can provide safety guarantee, but also can control the rotation positioning of the cantilever beam by the high-altitude operation personnel according to the requirement, thereby having the advantages of strong applicability and convenient use. And when not operating, the cantilever beam can rotate and stop in the position that does not influence work piece handling space, helps improving the operating efficiency.

The utility model is further perfected in that the cantilever beam is provided with lifting ring bolt mounting holes distributed at intervals, so that the hanging position of the safety belt or the safety cable can be adjusted according to the operation requirement.

The utility model is further perfected in that the end part of the positioning pin is a ball head, so that the positioning pin can be conveniently and smoothly inserted into the positioning hole.

Detailed Description

Example one

The aerial work safety rope hanging device of the embodiment is as shown in fig. 1, an upper sleeve 3 ' and a lower sleeve 3 are respectively fixed at a proper height of a vertical column 11 by fasteners, and a horizontal upper connecting seat 4 ' and a horizontal lower connecting seat 4 extend from the lower end of the upper sleeve 3 ' and the upper end of the lower sleeve 3 respectively.

The vertical pin shaft 5 with the upper end passing through the cap head and the lower end axially positioned by the nut is inserted into the corresponding position through holes of the upper connecting seat 4' and the lower connecting seat 4. A sleeve 6 positioned between the upper connecting seat 4' and the lower connecting seat 4 is sleeved outside the vertical pin shaft 5, and the sleeve 6 is welded and extended to form a horizontal cantilever beam 1 which is used for hooking the safety cable and is provided with a reinforcing rib 2. The cantilever beam 1 is provided with lifting ring bolt mounting holes which are distributed at intervals, and the hanging position of the safety belt or the safety cable 12 can be adjusted according to the requirement.

The lower end of the sleeve 6 is fixedly connected with a porous pin base 7 with positioning holes distributed at intervals in the circumferential direction in a welding mode. The lower sleeve 3 is provided with a telescopic positioning pin 9 driven by a remote control motor 10 through a mounting plate 8 fixedly connected with the lower sleeve. The upper end reducing end part of the positioning pin 9 is a ball head and is easy to insert into the positioning hole.

When the motor 10 is controlled by a remote controller to drive the positioning pin 9 to lift up one of the positioning holes inserted into the porous pin seat 7, the sleeve 6 and the cantilever beam 1 fixedly connected with the sleeve are positioned angularly. Thereafter, as shown in fig. 2, the operator standing on the large pressure vessel 13 can work safely. When the motor 10 is controlled by the remote controller to drive the positioning pin 9 to retract and exit the positioning hole of the porous pin seat 7, the sleeve 6 has angular degree of freedom, and the angular position of the cantilever beam 1 can be adjusted as required and then repositioned; for example, the lifting mechanism can be adjusted to a position which does not affect the lifting space of the workpiece after the operation is finished, so that convenience is provided for subsequent work.

In addition to the single-arm operation state shown in fig. 2, two groups of safety rope suspension devices for ascending operation can be used in a matched manner as shown in fig. 3, namely the safety rope suspension devices are fixedly connected to two bearing upright columns 11 of a factory building respectively, and the two cantilever beams 1 are rotated to parallel positions for angular positioning. And then, the end parts of the two cantilever beams 1 are tensioned by a steel wire rope 14 with a safety buckle at the end (see fig. 4), and the steel wire rope 14 is hung with a safety rope 12, so that the long-distance ascending operation requirement of one or more operators can be met.

Practice shows that in the embodiment, the high-altitude operation personnel can control the rotation positioning of the cantilever beam by self, so that the operation is very convenient and is more beneficial to ensuring the safety; and the operation of the subsequent work is not influenced after the operation.

In addition to the above embodiments, the present invention may have other embodiments, and all technical solutions formed by equivalent transformation fall within the scope of the claims of the present invention.
