Description

A kind of portable Work tool drop-proof lifting device

Technical field

The utility model relates to a kind of Work tool lifting device, relates in particular to a kind of Work tool drop-proof lifting device during for power transmission lines overhauling.

Background technology

In power transformation operation work, often there is 10kV circuit to turn the operation of maintenance.Operations staff need to climb to the position of 7-10 rice and carry out operation along the cat ladder of outlet isolating switch steel tower, and need to take the Work tools such as earth connection, electroscope to job position.According to power industry relevant regulations, during high-rise working, transmit up and down object and should transmit with rope bolt jail, in real work, need to carry out in strict accordance with this regulation.So earth connection operation will be carried out following steps: 1) toggle Work tool on ground with rope; 2) operating personnel carry the rope other end and climb to operation plane; 3) operator fixes the safety belt of oneself; 4) with rope, Work tool is pulled to operation plane; 5) Work tool is fixed.These work, dismounting is frequent, complex steps, Work tool is heavier, tractive effort, required time is long, and exists because operating personnel's hand is slided or is short of physical strength and draws the danger that incessantly rope causes Work tool to fall and damage, and severe patient can cause injury to personnel.

Utility model content

Technical problem to be solved in the utility model is, overcomes the above defect, and a kind of laborsaving, quick, safe portable Work tool drop-proof lifting device is provided.

In order to solve the above technical problem, a kind of portable Work tool drop-proof lifting device of the utility model, comprises anti-fall device, arrange junction button, hook be connected with the upper/lower terminal of described anti-fall device respectively; In the side of described anti-fall device, be provided with and carry galvanoscopic fastener.

Further, hook described in the utility model is that triangle is opened or trapezoidal, and described triangle or each trapezoidal angle are fillet.

The beneficial effects of the utility model: owing to having used the above technical scheme, the utlity model has advantage easy and simple to handle, time saving and energy saving, fast and safely, for operating personnel have alleviated burden, reduced the risk of high-rise working, guaranteed the person and device security.

Fig. 2 is the structural representation of triangular hook;

The structural representation of the trapezoidal hook of Fig. 3;

Fig. 4 is the structural representation of fastener.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

A kind of portable Work tool drop-proof lifting device of the utility model, comprises anti-fall device 1, junction button 2 is set, hook 3 is connected with the upper/lower terminal of described anti-fall device 1 respectively; In the side of described anti-fall device 1, be provided with and carry galvanoscopic fastener 4.

Further, hook 3 described in the utility model is triangle or trapezoidal, and described triangle or each trapezoidal angle are fillet.

Embodiment: anti-fall device 1 described in the utility model adopts the catching device on market to improve and forms, and because catching device can be used in conjunction with the existing track of shaft tower, has the sliding function of automatic limiting, can directly prevent from falling.The safety rope of existing catching device is removed, moved a hole clipping and fix on the brace at catching device middle part, two holes of side opening at catching device, obtain anti-fall device 1 described in the utility model; Junction button 2 adopts the safety buckle of existing catching device, soon quick-mounting, tear open, anti-fall reliability is high, abrasion resistance properties is strong, load-bearing is greater than 10kg; Described hook 3 is earth connection sprung parts, selects reinforcing bar material, is made into triangle or trapezoidal, each angle is made into fillet, and opening part welding, is connected with described anti-fall device 1 lower end bayonet socket, can hang up three-phase ground line, hang solid and reliablely, be convenient to fix; Insert the tube and pipe of aluminium alloy that galvanoscopic fastener 4 adopts diameter 5cm, Material Strength is high, not yielding, both artistic and practical, in the inside and outside both sides of pipe upper/lower terminal, correspondence is made a call to four holes, two holes of inner side are smaller, fixing for linking with screw and anti-fall device 1 side, two holes in pipe outside are bigger, when fastener 4 links with anti-fall device 1, facilitate screw and instrument to enter operation in pipe, with this, fastener 4 is fixed on to the side of anti-fall device 1; Fastener 4 can insert conventional 10kV electroscope.

During use, portable Work tool drop-proof lifting device described in the utility model is linked together by junction button 2 and the catching device for staff, successively the catching device for staff and the described anti-fall device 1 of this practicality are placed in iron tower falling-proof track, earth connection is hung on described hook 3, electroscope inserts fastener 4 and fixes, the active force of upwards stepping on tower by human body takes the Work tools such as earth connection and electroscope to service position, in this process, person catching device and Work tool drop-proof lifting device possess anti-drop function separately, realize " dual fail-safe ", the safety and the Work tool that guarantee staff do not drop.

Use the utility model, before stepping on tower during setting tool device, no longer need rope to fasten, but " hanging steady ", Work tool is transported to after operation plane, also do not need other extra operations, Work tool just can firmly be clamped on anti-fall track under the effect of self gravitation and the sliding function of device limit, has greatly reduced the operating time; Because device has the sliding function of automatic limiting, even if there is the situation of being short of physical strength, hand is sliding in personnel, Work tool also can be when gliding automatic locking, avoided falling, reduce operating risk.

Claims (2)

1. a portable Work tool drop-proof lifting device, comprises orbit cage dog part (1), it is characterized in that, arrange junction button (2), hook (3) be connected with the upper/lower terminal of described orbit cage dog part (1) respectively; In the side of described orbit cage dog part (1), be provided with and carry galvanoscopic fastener (4).

2. a kind of portable Work tool drop-proof lifting device according to claim 1, is characterized in that, described hook (3) is triangle or trapezoidal, and described triangle or each trapezoidal angle are fillet.
