Description

Power pole climbing protector

technical field

The utility model relates to a tool for climbing a tower in electric power construction, in particular to an anti-falling protection device for electric power construction personnel to go up and down a pole tower. the

Background technique

The power line part (Trial) of the "Electricity Safety Work Regulations" issued by the State Grid Corporation stipulates: "Any work carried out at a location 2m or above from the ground (fall height datum) shall be regarded as a high-altitude operation; When working at heights on pole towers, double safety safety belts with backup ropes should be used. The safety belts and safety ropes should be hung on the firm components of different parts of the tower respectively to prevent the safety belt from falling out of the top of the pole or being damaged by sharp objects. , the hand-held components must be firm, and must not lose the protection of the backup rope." During construction on poles and towers, safety ropes are often used. A safety rope (that is, a safety rope) is tied around the operator’s waist, and the safety buckle on the outer end of the safety rope is hung on the structural angle steel of the tower. The rope will stop the human body from falling downward. But existing safety rope can not be used for the anti-drop protection of personnel when going up and down the tower pole. the

In addition, for a long time, the power sector has used pedals or foot buckles to work on the upper and lower towers in the construction, maintenance, and repair of power lines. Its safety is poor and it cannot provide reliable safety protection for the safety of construction personnel. the

Utility model content

The purpose of the utility model is to provide a convenient, practical, safe and reliable power tower climbing protector. the

The purpose of this new model is achieved in this way: a climbing protector for power poles and towers, including a speed difference automatic controller, the metal hook is welded on the connecting rod, the connecting rod is fixed on the top of the insulating rod, and the speed difference automatic controller is fixed on the connecting rod , the lower end of the steel cable of the speed difference automatic controller is fixed with a safety buckle for the safety rope to be inserted into. the

The above-mentioned speed difference automatic controller is fixed on the connecting rod through the wire rope. the

The above-mentioned insulating rod is a multi-section insulating rod: its basic unit consists of a rod member screwed between two pipe joints. the

The above connecting rod is screwed and fixed on the top of the insulating rod. the

The above-mentioned speed difference automatic controller is a 3m speed difference automatic controller. the

The beneficial effects of the utility model are:

1. Simple structure and low manufacturing cost.

2. The upper and lower towers are easy to use, safe and reliable. the

The speed difference automatic controller (prior art) is also called a fall arrester, which can quickly brake and lock falling objects within a limited distance. It uses the speed difference of falling objects for self-control, and its safety rope (steel cable) is always in a tense state, so that construction workers can work easily and freely. Once a fall occurs, the pull-out speed of the safety rope is accelerated, and the control system inside the device is automatically locked, so that the (wire rope) safety rope does not fall more than 0.2 meters. It can effectively guarantee the personal safety of personnel. Before climbing up the pole tower, put the upper end of the insulating pole (generally 4-5m long, three-section telescopic structure can be used, such as the existing rod antenna structure, which is formed by inserting the lower part of the previous pipe joint into the upper part of the next pipe joint) The metal hook is hung on the structural angle steel of the tower at a height of 4-5m above, and the outer end of the safety rope tied on the person is set in the safety buckle (that is, the steel cable with the speed difference automatic controller, also known as the speed difference The safety rope of the automatic controller is fixed). The steel cable of the speed difference automatic controller is slowly pulled out as the person climbs upwards. If a person falls during the climbing process, the pulling speed of the steel cable rises sharply, and the control system in the speed difference controller is automatically locked, so that the steel rope The length of the sudden extension of the cable does not exceed 0.2m, even if the height of the person falling does not exceed 0.2m, it provides an effective protection against falling for the personnel on and off the tower during the climbing process. the

Detailed ways

Fig. 1 shows that the utility model includes a speed difference automatic controller 4, and the metal hook 3 is welded on the connecting rod 2, and the connecting rod 2 is fixed on the top of the insulating rod 1, and the speed difference automatic controller 4 is fixed on the connecting rod 2, and the speed difference automatic controller 4 is fixed on the connecting rod 2. A safety buckle 5 for the safety rope to be inserted is fixed on the steel cable 4a lower end of the differential automatic controller. The speed difference automatic controller 4 is fixed on the connecting rod 2 through a wire rope. The insulating rod 1 is a multi-section insulating rod: its basic unit consists of a rod member screwed between two pipe joints. The connecting rod 2 is screwed and fixed on the top of the insulating rod. The speed difference automatic controller 4 is a 3m speed difference automatic controller. Figure 2 shows the existing safety buckle. A downward force is applied to the upper left side of the safety buckle (the upper and lower parts are on the left), and the left upper and lower parts that are fastened to each other are separated (that is, the upper part is shifted inward) to form an opening, which can be removed from the opening. Put the safety rope into the buckle, and after losing the external force, the safety buckle can return to the locked state in Figure 2. the

The insulating rod is 4-5m long (three high-strength brake rods can be selected, which is easy to carry), with a metal hook at one end (the metal hook should have strong mechanical strength and can be reliably hung with the metal hook frame), and the speed difference automatic controller 3 m speed difference automatic controller can be selected. Before going up (down) the tower, the safety rope around the waist of the operator can be reliably connected with the steel cable (that is, the safety rope) of the speed difference automatic controller. Before going up (down) the tower, slowly pull out the steel cable of the speed difference automatic controller, first hang the metal hook of the protector up (down) on the reliable frame (or foot nail) of the tower, and then up ( Down) climbing, at this time the steel cable of the speed difference automatic controller will automatically shrink into the speed difference automatic controller (the steel cable of the speed difference automatic controller will move down slowly with the person when the tower is lowered, and it will automatically move the steel cable in the speed difference automatic controller Slowly pull out the cable), this method is simple and practical, and under the condition of correct use, it provides a reliable protection against falling for the tower high-altitude workers in the process of going up and down. After passing the test, this product complies with relevant technical characteristics and relevant national safety standards. the
