Description

Meter box lifting tool

technical field

The utility model relates to the technical field of power transmission line auxiliary equipment in the electric power industry, in particular to a hoisting tool for an electric meter box. It is used to lift the box when installing the meter box.

Background technique

With the rapid growth of electricity consumption, a large number of new users and the transformation of the old network, the installation and transformation of the meter box is a heavy task. Just take the 0.4 kV power distribution line as an example. The meter box is usually installed in a small space, and due to environmental restrictions, it is not possible to use large-scale hoisting equipment. At present, the installation and operation of the meter box usually use the staff to manually lift the box to a higher place, and then fix it by other personnel. On the wall, many people are required to cooperate to complete it. The construction method is backward, time-consuming and labor-intensive, the labor intensity of the workers is high, the work efficiency is low, and there are potential safety hazards during operation.

Contents of the invention

The purpose of the utility model is to provide a meter box hoisting tool, which overcomes the deficiencies in the prior art, saves labor, saves time and effort, and improves work efficiency.

The technical scheme of the utility model is: comprising a ratchet type wire tensioner, and also including a rod body, a fixed pulley, an arc support arm, and a suspension rope; a fixed pulley is installed on the top of the rod body, and two legs are fixed at the lower end of the rod body; The middle part of the arm is fixed on one side of the upper part of the rod body, the ratchet type wire tensioner is assembled in the middle part of the other side of the rod body, the arc-shaped support arm and the ratchet type wire tensioner are respectively located on both sides of the rod body; Through the fixed pulley at the top of the rod body, the other end of the stay rope is connected with the middle part of the suspension rope; a hook is respectively installed at both ends of the suspension rope.

Further, the rod body is a two-section telescopic structure, and the upper rod body is inserted into the lower rod body and positioned by bolts.

The utility model has the advantages of simple and reasonable structure and low production cost. When installing the electric meter box, the arc-shaped support arm of the hoisting tool rod body is pressed against the wall, and the box body is lifted by a ratchet-type wire tensioner, and the ratchet is used for self-locking. The mechanism makes the box hang in the air instead of manual work, which saves time and effort, reduces the labor intensity of construction personnel, shortens the installation time, and improves work efficiency.

The technical scheme of the utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is a schematic diagram of the working state of the utility model.

Detailed ways

Among the figure: 1. rod body, 2. supporting feet, 3. ratchet type wire tensioner, 4. fixed pulley, 5. arc support arm, 6. sling, 7. hook, 8. electric meter box, 9. wall.

Example

As can be seen from Fig. 1, the utility model includes a ratchet type wire tensioner 3, and also includes a rod body 1, a fixed pulley 4, an arc support arm 5, and a suspension rope; the rod body 1 is a two-section telescopic structure, and the upper section rod body is inserted into the lower section The rod body is positioned by bolts; the top of the upper rod body is welded with two parallel struts, the fixed pulley 4 is fixed and installed on the struts through pin shafts, and the lower end of the lower rod body is welded and fixed with two legs 2; The support arm 5 is semicircular, and its middle part is welded and fixed on the upper side of the upper section of the rod body; the ratchet type wire tensioner 3 is welded and fixed on the middle part of the other side of the lower section of the rod body, that is, the arc-shaped support arm 5 and the ratchet type wire tensioner 3 They are respectively located on both sides of the rod body 1; the stay rope of the ratchet type wire tensioner 3 goes upwards around the fixed pulley 4 at the top of the rod body, and the other end of the stay rope is connected to the middle part of the suspension rope 6; a hook 7 is installed at each end of the suspension rope 6 .

When the utility model is in use, first adjust the length of the rod body 1 to the required height, and place the hoisting tool on the side of the wall, so that the legs 2 stand on the ground, and the two ends of the arc support arm 5 are supported on the wall, and the rod body The fixed pulley 4 at the top of 1 is close to the wall, and a triangular hoisting working space is formed below the rod body. Rotate the rocking handle of the ratchet type wire tensioner 3, loosen the wire tensioner stay rope, then the wire tensioner stay rope passes between the inner side of the arc support arm 5 and the wall; then hang the hooks 7 at both ends of the suspension rope 6 on On both sides of the meter box; reversely turn the handle of the wire tensioner to tighten the pull rope, and lift the meter box along the wall to the installation height. Due to the self-locking mechanism of the ratchet-type wire tensioner 3, the meter box can be hovered at any height, instead of manual lifting, which solves the problems of time-consuming and labor-intensive installation of the meter box and low installation efficiency, especially when installing a large meter box. It greatly reduces the labor intensity and work difficulty of the staff, reduces the number of construction workers, ensures the safety of the staff, eliminates potential safety hazards in the work, and effectively improves work efficiency.

Finally, it should be noted that: the above examples are used to illustrate the technical solution of the utility model rather than to limit it. Those skilled in the art can modify the implementation or equivalently replace some technical features without departing from the technology of the utility model. The essence of the scheme should be covered within the scope of protection required by the utility model.
