The climbing work step stool comprises a frame body, traveling wheels and wiring holes, wherein the traveling wheels are symmetrically arranged at the upper end of the frame body and are used for supporting the frame body; and the wiring holes are formed at the two ends of the frame body. The climbing work step stool is characterized by also comprising a seat, a pair of limiting devices and a lifting device, wherein the pair of limiting devices are symmetrically arranged at the lower ends of the traveling wheels; the lifting device is used in cooperation with the limiting devices; the frame body and the seat are hinged through a supporting seat fixedly arranged on the frame body; and safety belt fixed holes are symmetrically formed on the seat. In the lifting process, a limiting clamp of a self-locking device automatically opens; and after an ultrahigh voltage cable contacts with the traveling wheels successfully, a rope of a lifting pull ring is loosened and the limiting clamp of the self-locking device automatically closes, so the locking work is finished.
Description
Technical field
The utility model relates to a kind of truck work step stool that has the rumble seat that is used for electrification in high voltage work.
Background technology
Livewire work at present is as an important indicator that reduces the electric power maintenance cost, and charged functions of the equipments and the structure of ascending a height commonly used at present is comparatively simple, can't satisfy the safety requirements standard of livewire work; Or use inconvenient, thereby fatiguability when causing the long-term charged work of staff, thereby cause various safety problems; When ascend operation; The rope ladder head of ascending a height only carries out spacing through gravity, if personal position run-off the straight or accidentally drop and will cause people's height to fall causes personal injury.Existing livewire work rope ladder head does not install the high-altitude self-locking device additional; Can only be that the operating personnel arrives aerial finger lock and seals up a door; Open earlier before the following rope ladder and seal up a door, otherwise rope ladder head can't extract, this has just caused the work high above the ground personnel up and down during rope ladder; There is the danger that comes off in rope ladder head, and steps on the hidden danger that the rope ladder personnel exist height to fall.
The utility model content
The utility model technical problem to be solved provides a kind of truck work step stool that has the rumble seat that is used for electrification in high voltage work.
The utility model adopts following technical scheme:
The utility model comprises support body, is arranged at the symmetrically arranged road wheel that is used for supporting frame of support body upper end and the wiring hole that is arranged at the support body two ends; It is characterized in that it also comprises seat, is symmetricly set in a pair of stopping means of road wheel lower end and the lifting appliance that is used with stopping means; Said support body and seat are symmetrically arranged with the safety belt fixing hole through being fixedly set in the supporting seat hinge mutually on the support body on the said seat; Said stopping means is made up of spacing card, bearing pin and position-limiting spring leaf, and described spacing card and support body have position-limiting spring leaf around the home through pin hinge on the said bearing pin, and said position-limiting spring leaf one end and support body closely cooperate, the other end and spacing chucking close fit; Said lifting appliance by symmetrically arranged contiguous block, wire clamp, control line and be arranged at support body central authorities hoisting frame, hoisting frame limited post, promote draw ring and locking cap is formed; The lower end of said contiguous block is through wire clamp and control the line fixed-link; The said other end of controlling line is connected with hoisting frame through locking cap; The lower end of said hoisting frame is provided with the hoisting frame limited post that penetrates the support body crossbeam; Said hoisting frame limited post lower end is provided with stop nut, and said hoisting frame upper end is provided with the lifting draw ring.
Said support body is provided with wire clamp.
The good effect of the utility model is following:
The utility model has been set up rumble seat on original equipment of ascending a height, both reduced the work fatigue that the staff works long hours, and is simultaneously easy to carry, not extra taking up room; Also be provided with simultaneously the safety belt fixing hole on the seat; Between the equipment of ascending a height and its contacted high-voltage line, be provided with spacing card, ensured staff's safety problem; When promoting, only need lanyard on the lifting draw ring, in lifting process, the spacing card of self-locking device opens automatically; When super-pressure cable success with after road wheel contacts; Only need unclamp the rope of the draw ring of lifting, the spacing card auto-closing of self-locking device is accomplished locking work.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the A portion structure for amplifying sketch map of Fig. 1.
The specific embodiment
Like accompanying drawing 1, shown in 2; The utility model comprises support body 1, is arranged at the symmetrically arranged road wheel 2 that is used for supporting frame 1 of support body 1 upper end and the wiring hole 3 that is arranged at support body 1 two ends; It is characterized in that it also comprises seat 5, is symmetricly set in a pair of stopping means of road wheel 2 lower ends and the lifting appliance that is used with stopping means; Said support body 1 and seat 5 are symmetrically arranged with safety belt fixing hole 6 through being fixedly set in supporting seat 4 hinge mutually on the support body 1 on the said seat 5; Said stopping means is made up of spacing card 7, bearing pin 8 and position-limiting spring leaf 9; Described spacing card 7 passes through bearing pin 8 hinges with support body 1; On the said bearing pin 8 position-limiting spring leaf 9 is arranged around the home, said position-limiting spring leaf 9 one ends and support body 1 closely cooperate, and the other end and spacing card 7 closely cooperate; Said lifting appliance by symmetrically arranged contiguous block 10, wire clamp 11, control line 12 and be arranged at support body 1 central authorities hoisting frame 13, hoisting frame limited post 14, promote draw ring 15 and locking cap 16 is formed; The lower end of said contiguous block 10 is through wire clamp 11 and control line 12 fixed-link; The said other end of controlling line 12 is connected with hoisting frame 13 through locking cap 16; The lower end of said hoisting frame 13 is provided with the hoisting frame limited post 14 that penetrates support body 1 crossbeam; Said hoisting frame limited post 14 lower ends are provided with stop nut, and said hoisting frame 13 upper ends are provided with and promote draw ring 15.
The utility model has been set up rumble seat 5 on original equipment of ascending a height, both reduced the work fatigue that the staff works long hours, and is simultaneously easy to carry, not extra taking up room; Also be provided with simultaneously safety belt fixing hole 6 on the seat; Between the utility model and its contacted high-voltage line, be provided with spacing card 7, ensured staff's safety problem; When promoting, only need lanyard on lifting draw ring 15, in lifting process, the spacing card 7 of self-locking device opens automatically; When super-pressure cable success with after road wheel 2 contacts; Only need unclamp the rope that promotes draw ring 15, spacing card 7 auto-closings of self-locking device are accomplished locking work.
