Detailed description of the invention
Below in conjunction with Figure of description, the present invention is described below.
As shown in the figure, a kind of electric power overhaul lifting appliance, comprise lifting case 4, lifting power plant and jacking system, wherein said jacking system comprises fixed pulley group 8, running block 7 and stay cord 10, the head end of described stay cord 10 is connected with described fixed pulley group 8, end is walked around running block 7 successively and is connected with described lifting power plant with after fixed pulley group 8, described fixed pulley group 8 is provided with top clips 9, when lifting, top clips 9 is arranged on one of them electric pole, described lifting case 4 is provided with some lifting ropes 6, described lifting rope 6 top pools together and is connected with described running block 7, easy to operate when lifting like this, not only can guarantee the steady lifting lifting case 4, but also certain protective effect can be played to voltage transformer, detouchable stay bearing plate 5 is provided with bottom described lifting case 4, after voltage transformer hangs assigned address, directly stay bearing plate 5 is dismantled from lifting case 4, such voltage transformer just can directly drop out from the bottom of lifting case 4, thus complete whole lifting work.
Described lifting power plant comprises cabinet 1, and be positioned at the motor 12 of cabinet 1, bottom clips 2 is provided with outside described cabinet 1, by bottom clips 2, cabinet 1 is fixed on the bottom of electric pole during lifting, two bracing frames 171 are at least provided with in described cabinet 1, support frame as described above 171 is provided with transmission shaft 17, described transmission shaft 17 is connected with support frame as described above 171 by bearing 172, bracing frame 171 is for supporting shaft 17, described motor 12 is connected with one end of described transmission shaft 17, the switch rotated for controlling described motor 12 is had at described cabinet 1 peripheral hardware, described transmission shaft 17 is provided with wire spool 11, the end of described stay cord 10 is fixedly connected with described wire spool 11, the rotation of motor 12 drives wire spool 11 to rotate, thus pull stay cord 10 to drive lifting case 4 to rise.
Reel 18 is provided with at the other end of described transmission shaft 17, joystick 19 is provided with outside described reel 18, described transmission shaft 17 is provided with stop mechanism, when adopting manual mode to lift by crane, drive reel 18 to rotate by shake joystick 19, then drive wire spool 11 to rotate by transmission shaft 17, in lifting process when workman needs to leave, now can be pinned by transmission shaft 17 by stop mechanism, what prevent transmission shaft 17 rotates backward the situation that voltage transformer is dropped.
Described stop mechanism is disc brake system, described transmission shaft 17 is provided with disc 16, cabinet 1 above described disc 16 is provided with clamp 15, and the useful spiral button 13 with controlling the opening and closing of described clamp 15 at described cabinet 1 peripheral hardware, spiral button 13 is connected with clamp 15 by steel rope 14.
Side outside described lifting case 4 is provided with socket, with the lifting case 4 of described socket same level position in be provided with support chute, be connected with described lifting case drawing and pulling type by supporting chute after described stay bearing plate 5 inserts described socket, described stay bearing plate 5 is provided with some roller bearings 51, the front end of described stay bearing plate 5 is ramp structure, after voltage transformer is lifted into assigned address, directly by stay bearing plate 5 from pull bottom lifting case 4 out, when pulling stay bearing plate 5, owing to being provided with roller bearing 51 on the supporting plate, thus the friction reduced between stay bearing plate 5 and voltage transformer, simultaneously because the front end of stay bearing plate 5 is ramp shaped, make voltage transformer can slowly reduction height, final pulsation-free is fallen on support.
Skid off in lifting case 4 to prevent stay bearing plate 5, therefore above described socket, locating dowel pin 40 is provided with, the knock hole 52 that can coordinate with described locating dowel pin 40 is provided with at described stay bearing plate 5 end, when lifting, locating dowel pin 40 being inserted in knock hole 52, so just can play positioning action to stay bearing plate 5.
Be provided with slip hoop 3 in the side of described lifting case 4, in described slip hoop 3, be provided with some balls 31, during lifting, slip hoop 3 be stuck in outside electric pole, in lifting process, just well avoid the situation that lifting case 4 swings like this.
Its principle of work is: be first fixed in fixed pulley group 8 by the head end of stay cord 10 before lifting, then the end of stay cord 10 to be had mercy on successively running block 8 and fixed pulley group 7, finally the end of stay cord 10 is fixed on wire spool 11, stay cord 10 was when having mercy on fixed pulley group 8 and running block 7, the suitable winding number of turns can be selected according to the weight of voltage transformer, dynamics required when this reduces hand-operated lifting, then by top clips 9, fixed pulley group 8 is fixed on the top of electric pole, by bottom clips 2, cabinet 1 is fixed on the bottom of electric pole, first the lifting rope 6 on lifting case 4 is suspended on running block 7 when lifting, then lifting case 4 slip hoop 3 is once fitted with electric pole, when lifting by crane, lifting case 4 just can move up along electric pole like this, well avoid the situation that lifting case 4 swings, after voltage transformer is lifted into assigned address, lifting case 4 is placed on after on the support between electric pole, first the taking out positioning pin in knock hole 52 will be inserted in, then hold handle 53 on stay bearing plate 5 slowly pull stay bearing plate 5, now because be provided with roller bearing 51 on stay bearing plate 5, so the friction force between voltage transformer and stay bearing plate 5 is very little, after stay bearing plate 5 is completed extraction, voltage transformer has also just dropped on support completely, finally direct lifting case 4 to be hung away, in whole hoisting process, if when needing midway stopping lifting work, can by rotating spiral button 13, then pull steel rope 14 to control the closed of clamp 15, after clamp 15 are closed, clamp 15 are also just by disc 16 fixing inflexibly, disc 16 cannot be rotated again, and then play the restriction that transmission shaft 17 is rotated, even if voltage transformer is suspended in mid air and also can not drops like this, when needs proceed lifting, spiral button 13 is reversed, clamp 15 are unclamped from disc 16, so just crane lifting service can be proceeded.
