Abstract

The invention discloses a cross arm installer of a power distribution line. A primary hoop and a secondary hoop are butted to form a round form; a vertical plate is fixed at the lower end of the front side of the primary hoop; a brake bayonet lock is hinged with the left side of the lower part of the vertical plate and is flush with a plate; a bearing is inserted into the right side of the lower part of the vertical plate; the centers of a wheel disk and a brake gear pass through the bearing respectively; the upper end of a hand shank is fixed at the front end of the bearing; and the right end of the brake bayonet lock can be clamped to the upper edge of any sawtooth of the brake gear when inclining upwards, so that the brake gear cannot anticlockwise rotate and can clockwise rotate. The cross arm installer is convenient to carry; and cross arm installation through one-man high-place operation can be achieved, so that operation is time-saving and labor-saving.

Description

A kind of distribution line cross-arm erector

Technical field

The present invention relates to a kind of device for installing distribution line cross-arm for lifting and auxiliary.

Background technology

Power industry is at new frame line construction, track remodelling at present, and the lifting of cross-arm and installation are without specific purpose tool.Primarily now there is two ways: one is manpower lifting, fixing on two people's bars, another kind of crane lifting, fixing on two people's bars.The lifting of both mode manpowers is laborious, and crane lifting Financial cost is higher, and double operation on bar, narrow space, and the security risk that pendant thing and personnel fall easily occurs.

Summary of the invention

For solving the problem that prior art exists, the invention provides a kind of distribution line cross-arm erector, its technical scheme taked is:

Including hooping structure, wheeling disk structure and brake structure, hooping structure includes main anchor ear, secondary anchor ear and riser, main anchor ear and the secondary anchor ear rounded shape of docking and its front end are hinged, riser is fixed on the lower end, front side of main anchor ear, wheeling disk structure includes wheel disc, bearing and hands handle, brake structure includes spragging gear and braking bayonet lock, braking bayonet lock be hinged on riser lower left side and with plate face level, bearing insert riser bottom on the right side of and vertical with plate face, the center of wheel disc and spragging gear is each passed through bearing and is fixed on bearing, wherein wheel disc is positioned at before spragging gear, the adjustable in length of handle, the upper end of handle is fixed on the front end of bearing, the upper edge of the arbitrary sawtooth of spragging gear is may be stuck in when braking the right-hand member updip of bayonet lock, make spragging gear not rotate counterclockwise and can rotate clockwise.

Main anchor ear and secondary anchor ear are for securing the device to the top of electric pole, spragging gear on braking bayonet lock and wheel disc collectively constitutes backstop, prevent falling and temporarily holding cross-arm height in cross-arm lifting process, by adjusting the length of telescoping handle, rotary handle, cross-arm is gradually risen to precalculated position by the steel wire rope being wound around on wheel disc.The present invention is applicable to new frame line construction, track remodelling etc. needs to install the operation of cross-arm, greatly improve cross-arm installation effectiveness, shorten the engineering time, solve the problem that traditional-handwork is wasted time and energy, operating personnel on the most less bar, improves the safety of construction.

Detailed description of the invention

The present invention will be further described below in conjunction with the accompanying drawings.

As in figure 2 it is shown, hooping structure includes main anchor ear 1, secondary anchor ear 2 and riser 3, main anchor ear 1 docks rounded shape with secondary anchor ear 2 and its front end is hinged, and riser 3 is fixed on the lower end, front side of main anchor ear 1.As shown in Figure 3 and Figure 4, wheeling disk structure includes wheel disc 4, bearing 5 and handle 6, brake structure includes spragging gear 7 and braking bayonet lock 8, braking bayonet lock 8 be hinged on riser 3 lower left side and with plate face level, bearing 5 inserts on the right side of the bottom of riser 3 and vertical with plate face, the center of wheel disc 4 and spragging gear 7 is each passed through bearing 5 and is fixed on bearing 5, wherein wheel disc 4 is positioned at before spragging gear 7, wheel disc 4 uses H type structure, facilitate lay winding wire ropes, the upper end of handle 6 is fixed on the front end of bearing 5, handle 6 is made up of outdoor handle 9 and inner handle 10, inner handle 10 embeds inside outdoor handle 9, fixed by handle bolt 15, make adjustable.

As it is shown in figure 1, when installing cross-arm 13, operating personnel carry this device, open the secondary anchor ear 2 on hooping structure and be buckled in the top of electric pole 14, penetrate bolt at main anchor ear 1 and secondary anchor ear 2 rear end so that it is fixedly secure on electric pole 14.Braking bayonet lock 8 is placed in A condition, and both its upper end "Left"-deviationist was shelved on pivot pin 11, and pivot pin 11 is fixed on riser 3, and the steel wire rope 12 on 6 wheel discs 4 of handle puts down.When ground paraprofessional personnel is fixed on cross-arm 13 on steel wire rope 12, braking bayonet lock 8 being placed in B state, the right-hand member updip both having braked bayonet lock 8 may be stuck in the upper edge of the arbitrary sawtooth of spragging gear 7, makes spragging gear 7 not rotate counterclockwise.Adjust the length of handle 6, rotary handle 6, make bearing 5 drive wheel disc 4 to rotate clockwise, gradually cross-arm 13 is risen to precalculated position, penetrate U-bolt or yoke plate and both may be used fixing for cross-arm 13.
