Abstract
The utility model discloses a portable hoister, in particular a device special for electric power operation. The portable hoister comprises a clamping hoop, a hoisting support and a pulley, wherein the clamping hoop is fixedly connected to one end of the hoisting support, and the pulley is connected to the other end of the hoisting support; the clamping hoop comprises a left clamping hoop and a right clamping hoop which have a semi-circular structure; wing plates which extend outwards and are provided with bolt holes are arranged at two ends of the left clamping hoop and the right clamping hoop; and according to the left clamping hoop and the right clamping hoop, one end of the left clamping hoop and one end of the right clamping hoop are connected by a pin, and the other end of the left clamping hoop and the other end of the right clamping hoop are provided with clamping buckles which are matched with each other. According to the portable hoister, the personal safety of operating personnel on poles is ensured effectively by the connection of two protective ropes and the clamping hoop; and operating personnel on the ground pulls cross arm hardware to the tops of the poles by the pulley, so that the labor intensity of the operating personnel on the poles is reduced greatly.
Description
Technical field
The utility model relates to a kind of electric power operation isolated plant, and a kind of homework of supplying power personnel draw high the portable hoisting device that the cross-arm gold utensil is used toward masthead to the electric pole construction operation time specifically.
Background technology
Along with the fast development of China's economic construction, to the also sharply increase of demand of electric power, shaft tower in a large number therefore just need to erect power transmission lines.The operating personnel is in to the electric pole construction operation at present; before the masthead gold utensil is not installed; the operating personnel can't install two pipe protection ropes on bar; can only rely on both hands to encircle electric pole; play and support operation above the waist; both hands can't be discharged, and operating personnel's personal safety has been consisted of great threat.And the operating personnel is when drawing the cross-arm gold utensil with rope on the bar, stressed falling fully on the bar with it the operating personnel, and safety hazard further strengthens, and labour intensity is larger when boosting metal tool, is unfavorable for operating personnel's construction operation.
The utility model content
The utility model technical issues that need to address provide a kind of simple and reasonable, easy to use safe portable hoisting device that is applicable to use on the electric pole.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of portable hoisting device comprises hoisting bracket, an end jointing clip of hoisting bracket, and the other end is connected with pulley.
Further improvement of the utility model is: described clip comprises the left clip of semi-circular structure, right clip.
Further improvement of the utility model is: the equal correspondence in two ends of described left clip, right clip is provided with outward extending wing plate with bolt hole.
Further improvement of the utility model is: described left clip, right clip one end connect with pin, and the other end arranges the buckle of mutual coupling.
Because the technological advance that has adopted technique scheme, the utility model to obtain is:
The utility model has related to a kind of portable hoisting bracket; the operating personnel is when the operation of electric pole masthead; be fastened on the electric pole with bolt or the buckle clip with portable hoisting device, and with its with it two pipe protection ropes be fixed on the clip, effectively protected operating personnel's inherently safe on the bar.The pulley gear of Ground Operation personnel by hoisting bracket one end draws high masthead with the cross-arm gold utensil, makes on the bar operating personnel be convenient to fitting operation, greatly alleviated operating personnel's labour intensity on the bar.The left clip of the utility model design, the two ends of right clip connect with bolt, and the convenient elasticity of adjusting clip is applicable to the electric pole of different-diameter.

Fig. 2 is birds-eye view of the present utility model;
Wherein, 1, clip, 2, hoisting bracket, 3, pulley, 4, bolt.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further details.
Embodiment 1
A kind of portable hoisting device as shown in Figure 1 and Figure 2, comprises clip 1, hoisting bracket 2, pulley 3.Described clip 1 comprises the left clip of semi-circular structure, right clip; The two ends of described left clip, right clip arrange outward extending wing plate, on the described wing plate bolt hole are set; Described hoisting bracket 2 is fixedly welded on the right clip, and the end of hoisting bracket 2 connects the pulley 3 that is used for the handling gold utensil.
The operating personnel is upper during to the electric pole masthead; at first with rope portable hoisting device is risen to masthead; then clip 1 is enclosed within the electric pole masthead; with bolt 4 with left clip, right clip captive joint; support hoisting bracket; then the operating personnel with its with it two pipe protection ropes be fixed on the clip 1, thereby reach the inherently safe purpose of operating personnel on the guard bar.After clip 1 is fixing, by pulley 3 devices of Ground Operation personnel by hoisting bracket one end, the cross-arm gold utensil is drawn high masthead, assist that the operating personnel implements operation on the bar, play the effect that alleviates operating personnel's labour intensity on the bar.The left clip of the utility model design, the two ends of right clip connect with bolt, and the convenient elasticity of adjusting clip is applicable to the electric pole of different-diameter.
Embodiment 2
Embodiment 2 is with the difference of embodiment 1: described left clip, right clip one end are connected with pin, and the other end arranges the buckle of mutual coupling.In implementation process, the operating personnel rotates take pin as axle the left clip of clip 1, right clip is stuck in the electric pole masthead after separately again, and then the buckle of the mutual coupling by other end setting is fixed.
Claims (4)
1. portable hoisting device is characterized in that: comprise hoisting bracket (2), and an end captive joint clip (1) of hoisting bracket (2), the other end is connected with pulley (3).
2. described a kind of portable hoisting device according to claim 1, it is characterized in that: described clip (1) comprises the left clip of semi-circular structure, right clip.
