Description

Disconnecting switch Special lifting device
Technical field
The present invention relates to disconnecting switch disassemblerassembler more particularly to a kind of disconnecting switch Special lifting devices.
Background technique
With the swift and violent growth of regional economy, power demand also be increased dramatically, and be badly in need of increasing line segregation to substation It is extended.Meanwhile in order to ensure the safe and stable operation of entire power grid, disconnecting switch is also required to carry out according to relevant regulations big It repairs.Either newly-increased or overhaul, general there are two types of disconnecting switch arrangement and method for construction: first is that bus power cut construction, though this mode It is so comparatively safe, but the construction time is difficult to determine, workload is very huge and to power supply reliability there are larger threat, because This program is superseded.Second is that bus charging construction, is lifted by crane with crane in the case where not having a power failure and is installed, since crane takes up an area Area is big, is influenced by construction surrounding terrain, and crane cannot be introduced into, and lift disconnecting switch operation and its inconvenience.
Summary of the invention
The present invention is in order to solve the above-mentioned technical problem, to provide a kind of disconnecting switch Special lifting device, can reduce and account for Ground area is influenced from surrounding terrain, is lifted convenient for disconnecting switch.
The technical solution of the invention is as follows:
Disconnecting switch Special lifting device, including column are characterized in that the column is by support rod and to cover The support tube of support rod bottom is constituted;In support tube side wall, the electric pole oblique pull of about two groups arrangements and every group or so arrangement is set, The electric pole oblique pull is to be made of pull rod with the cuff that oblique pull outer end is arranged in;Motor, motor output shaft are set on support rod Reel is arranged in end, is wound with lifting rope on reel, in the fixed horizontal hanging arm of support bar top, boom bottom rear and front end is set respectively Pulley is set, the lifting rope free end bypasses each pulley from the front to the back and freely hangs through boom front end, and draws in lifting rope free end Two strands, suspension hook is respectively set in two strands of exits of lifting rope.
Further preferably, bearing is connected between the support rod and support tube, improves the rotational stability and reduction of support rod Frictional force between support rod and support tube.
Further preferably, support base is set in support tube bottom end, support tube is seated in ground by support base, improves whole The stability of structure.
The beneficial effects of the present invention are:
1, since the column is made of support rod and the support tube covered in support rod bottom, convenient for being arranged in support rod The boom on top horizontally rotates, and then the disconnecting switch position of lifting easy to remove.
2, it since about two groups arrangements and every group or so the electric pole oblique pull arranged are arranged in column side wall, will be stood by oblique pull Where column is indirectly fixed to disconnecting switch on electric pole, mounting structure is secured, stablizes, and reduces the occupied area of boom hoisting, exempts from It is influenced by surrounding terrain.
3, due to being wound with lifting rope on the reel at branch motor output shaft end, it is installed in the horizontal hanging arm bottom of support bar top Pulley is respectively set in portion rear and front end, and the lifting rope free end bypasses each pulley from the front to the back and freely hangs through boom front end, and Two strands are drawn in lifting rope free end, suspension hook is respectively set in two strands of exits of lifting rope, and two suspension hooks are hooked on disconnecting switch respectively Top two sides wind lifting rope by motor and are promoted in disconnecting switch promotion to the disconnecting switch mounting rack on electric pole, lifting isolation It is time saving and energy saving to switch, and lifts convenient for disconnecting switch.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention;
Fig. 2 is A-A cross-sectional view in Fig. 1;
1- support rod in figure, 2- support tube, 3- support base, 4- bearing, 5- pull rod, 6- cuff, 7- motor, 8- reel, 9- lifting rope, 10- boom, 11- pulley, 12- suspension hook.
Specific embodiment
As shown in Figure 1 and Figure 2, disconnecting switch Special lifting device, including column, the column are by support rod 1, cover The support tube 2 of 1 bottom of support rod and the support base 3 for being welded on 2 bottom end of support tube are constituted, and are connected between the support rod 1 and support tube 2 Joint bearing 4;The electric pole oblique pull of arrangement and every group or so arrangement about two groups of 2 sidewall weld of support tube, the electric pole oblique pull are It is made of pull rod 5 and the cuff 6 for being welded on oblique pull outer end;Motor 7 is installed on support rod 1,7 output shaft end of motor installs coiling 8 are taken turns, is wound with lifting rope 9 on reel 8, in 1 top weld horizontal boom 10 of support rod, 10 bottom rear and front end of boom is installed respectively Pulley 11,9 free end of lifting rope bypass each pulley 11 from the front to the back and freely hang through 10 front end of boom, and free in lifting rope 9 End draws two strands, and 9 two strands of exits of lifting rope are to have suspension hook 12 respectively.
When operation, support base 3 is seated in ground first, and cuff 6 is mounted on to the electric pole where disconnecting switch, then Two suspension hooks 12 are hooked on two sides at the top of disconnecting switch respectively, restarts motor 7 and winds lifting rope 9, disconnecting switch promotion is arrived On disconnecting switch mounting rack on electric pole and disconnecting switch is installed, finally takes suspension hook 12 from disconnecting switch, disassembly should be every Pass Special lifting device is left, operation is completed.
The above is only specific embodiments of the present invention, are not intended to restrict the invention, for those skilled in the art For member, the invention may be variously modified and varied.All within the spirits and principles of the present invention, it is made it is any modification, Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
