Abstract

The utility model relates to the technical field of maintenance and overhauling equipment for power transmission lines in the electric power industry, in particular to a portable lift. The operation of replacing old equipment on poles in transformer substations is commonly carried out by adopting sand wedge manual hoisting or large cranes. The problems of insufficient safety distances and the like exist in the sand wedge manual hoisting, and hoisting of the large cranes is often limited by sites. The portable lift comprises an electric motor, a speed reducing winch, vertical rods, a rotating mechanism and a suspension arm, wherein the vertical rods are connected through flanges, the middle portions of the vertical rods are connected with hoops through support arms, the rotating mechanism is composed of an inserting rod and a vertical shaft, the lower section of the vertical shaft is inserted into the inserting rod, the suspension arm is fixed at the top end of the vertical shaft, and the lower section of the inserting rod is inserted into the first section of the vertical rod at the upper end of the inserting rod and is connected with the first section of the vertical rod though a flange on the outer wall of the inserting pole. The portable lift has the advantages of being simple in structure and convenient to use. Detachable type design is adopted, and thus transportation and storage are convenient. The portable lift is free of the limitation of construction sites, reduces the labor intensity of operating personnel and improves the construction efficiency.

Description

A kind of Portable lifting machine

Technical field

The utility model relates to the Maintenance and Repair equipment technical field of power industry transmission line of electricity, specifically a kind of Portable lifting machine.

Background technology

Substation's day-to-day operation maintenance is changed aging and exists in the old equipment work of hidden danger, and the prior art lifting operation adopts husky bar manpower lifting or goliath operation usually.

Traditional husky bar manpower lifting mode is fixed because of Heave Here, after the lifting killer switch, must with rope, to the side traction, with chain sling, be lifted by crane again by the special messenger, have the problems such as the interval safety distance is not enough, work capacity is large, inefficiency, and husky pole length is long, transportation inconvenience; Application goliath lifting operation, although time saving and energy saving, limited by the substation place, sometimes need to enlarge power failure range and keeped in repair, and service expenditure is higher.Two kinds of forms of construction work all can not well meet on-the-spot needs.

Summary of the invention

The purpose of this utility model is to provide a kind of Portable lifting machine, to overcome deficiency of the prior art, reduces the labour intensity of operating personal, has improved work efficiency.

The technical solution of the utility model is: comprise electrical motor, deceleration winch, handwheel; Also comprise vertical rod, rotating mechanism and arm; The end of vertical rod is provided with flange, between every two joint vertical rods, by flange and bolt, connects; The vertical rod middle part connects anchor ear by support arm; Deceleration winch, electrical motor and handwheel are assemblied in the minor details vertical rod of lower end;

Rotating mechanism is comprised of insertion rod, vertical shaft; The vertical shaft top is fixed with arm, and a pulley respectively is equipped with at the arm two ends; Lifting rope is walked around two pulleys, and two ends connect respectively deceleration winch and suspension hook; The vertical shaft hypomere is inserted in insertion rod, between insertion rod and vertical shaft, passes through bearing fit; The vertical shaft lower end is provided with outside thread, and spacing by nut locking;

The outer wall of insertion rod epimere is provided with flange, and the hypomere of insertion rod is inserted in the first segment vertical rod of upper end, and the flange of first segment rod end is connected with the flange of insertion rod outer wall.

Further, the bearing fit between described rotating mechanism insertion rod and vertical shaft is, top is pressure bearing, and below is antifriction-bearing box.

Further, between the epimere of described vertical shaft and arm, strut bar is housed.

The utility model has the advantages that: simple in structure, easy to use, easy and simple to handle, solved the deficiency that the modes such as the husky bar lifting of prior art or crane loading exist, vertical rod adopts dismountable design, is convenient to transportation and storage, be not subject to the restriction of workyard, operating efficiency is high.

Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is elaborated.

The accompanying drawing explanation

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

The assembling schematic diagram that Fig. 2 is the utility model rotating mechanism and vertical rod.

The specific embodiment

In figure: 1, vertical rod, 2, vertical shaft, 3, flange, 4, arm, 5, pulley, 6, strut bar, 7, electrical motor, 8, the deceleration winch, 9, anchor ear, 10, insertion rod, 11, support arm, 12, electric pole.

Embodiment

As can be seen from Figure 1, the utility model comprises electrical motor 7, deceleration winch 8, handwheel; Also comprise vertical rod 1, rotating mechanism and arm 4; The two ends of vertical rod 1 are provided with flange, and middle part is connected with anchor ear 9 by support arm 11; Between every two joint vertical rods 1, by flange and bolt, connect; Deceleration winch 8, electrical motor 7 and handwheel are assemblied in minor details vertical rod 1 bottom, and the power take-off shaft of electrical motor 7 is connected with hand wheel shaft, and handwheel drives deceleration winch 8 by belt; In power failure or power free situation, can manually rotate the lifting that handwheel carries out equipment.

Rotating mechanism is comprised of insertion rod 10 and vertical shaft 2; Vertical shaft 2 hypomeres are inserted in insertion rod 10, and between insertion rod 10 and vertical shaft 2, by two bearing fits, top is pressure bearing, and below is antifriction-bearing box; Vertical shaft 2 lower ends are provided with outside thread, and spacing by nut locking; The outer wall of insertion rod 10 epimeres is provided with flange 3, and the hypomere of insertion rod 10 (being the following part of flange 3) is inserted in upper end first segment vertical rod 1, and the flange on first segment vertical rod 1 top and the flange 3 of insertion rod 10 are bolted; Arm 4 is assemblied in vertical shaft 2 tops, and a pulley 5 respectively is equipped with at arm 4 two ends; Lifting rope is walked around two pulleys 5, and two ends connect respectively deceleration winch 8 and suspension hook; Be equipped with oblique strut bar 6 between the epimere of vertical shaft 2 and arm 4.
