The suspension type service platform
Technical field
The utility model belongs to electrician's equipment special field, is a kind of transformer coil suspension type service platform.
Background technology
When electrician trade was produced big-and-middle-sized voltage transformer, high-voltage mutual inductor, the coil vertical that coiling is good was placed, and needed manual operation when assigning iron core original paper, insulation original paper thereon.Because about 3 ~ 4 meters of coil height is so the workman need just can finish the work by liftable service platform.
Similar service platform in the past is that platform is rigidly connected by platform lifting mechanism and its column of four jiaos, and motor-driven spiral lifting mechanism moves up and down, the elevating function of implementation platform.
This structure since four jiaos all be rigidly connected, so it is serious to cross the location, has produced and much be difficult to the shortcoming that overcomes.
1) machining accuracy is had relatively high expectations and is also very high for the technical requirements of platform installation, and this will strengthen the difficulty of manufacturing, and improve the productive costs of equipment;
2) resistance of lifting platform increases, and needs expanded motor power to solve;
3) four jiaos of worm drive paranema thick sticks that drive lifting of platform easily produce mechanical oscillation, thereby reduce the service life of worm drive pair;
4) in the lifting platform process, whole platform will produce stronger vibration, bigger noise.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned prior art deficiency, and a kind of later-model suspension type service platform is provided, and it has simple in structure, and is energy-conservation, and cost is low, the characteristics of good reliability.
The technical solution of the utility model is, designs a kind of suspension type service platform, which comprises at least platform, column, lifting mechanism, suspension rod, and it is characterized in that: column is built-in with liftable lifting mechanism, and lifting mechanism flexibly connects by suspension rod and platform.
Described platform is a rectangular platform, and four jiaos of rectangular platform are equipped with four columns respectively, all are equipped with lifting mechanism in each column, and platform flexibly connects on lifting mechanism by four jiaos suspension rod.
Described flexibly connecting to hinged is hinged between suspension rod and platform and the lifting mechanism.
Described suspension rod is to be convenient to pivotally attached connecting rod or steel rope.
Described lifting mechanism is made up of support, positioning and guiding wheel, worm drive pair, propulsion source, cross universal coupling, propulsion source and cross universal coupling are in transmission connection, cross universal coupling is connected with the worm drive auxiliary driving, cross universal coupling is a Collapsible structure, the worm drive pair is fixed on the support, worm drive simultaneously are secondary to be in transmission connection with the screw mandrel that is fixed in the column, support also is fixedly connected with the positioning and guiding wheel, the guide rail that guiding is arranged in the column, the positioning and guiding wheel places in the guide rail.
Characteristics of the present utility model are: the power that will drive the electrical motor generation of lifting platform inserts the input end of worm drive pair in the lifting mechanism by telescopic cross universal coupling, make the secondary power that obtains lifting of worm drive, it promotes lifting mechanism and moves together; Roll on the guide rail of positioning and guiding wheel in column in the lifting mechanism simultaneously, produce guiding and positioning action; Lifting mechanism pulling suspension rod moves together; Suspension rod drags platform one lifting again.
Because lifting mechanism and platform are to flexibly connect, and cross orientation problem so eliminated all, thereby have following advantage:
1) production and processing difficulty, field engineering difficulty are reduced greatly, thereby save cost;
2) eliminated owing to cross the resistance of motion that bring the location, reduced the power of lifting motor, energy-conserving action has been arranged;
3) improve the applying working condition of worm drive pairs, improved service life;
4) improve the stationarity of lifting platform, reduced the noise in the lifting platform process.

The specific embodiment
Embodiment 1
The suspension type service platform of present embodiment mainly is made up of platform 1, column 2, lifting mechanism 3, suspension rod 4.
Column 2 is built-in with liftable lifting mechanism 3, and lifting mechanism 3 flexibly connects by suspension rod 4 and platform 1, because platform 1 is flexibly connecting of floating, has solved between each column 2 or all mistake orientation problems between column 2 and the platform 1.
Embodiment 2
Platform 1 in the present embodiment is a rectangular platform, and four jiaos of platform 1 are equipped with four columns 2 respectively, see Fig. 1, all are equipped with lifting mechanism 3 in each column 2, and platform 1 flexibly connects on lifting mechanism 3 by four jiaos suspension rod 4.
Above-mentioned flexibly connects to hinged, is hinged between suspension rod 4 and platform 1 and the lifting mechanism 3, so platform 1 floats, and crosses orientation problems by suspension rod 4 hinged thorough solutions.
Above-mentioned suspension rod 4 goes back except adopting the pivotally attached connecting rod but steel rope etc. only limit the suspension member of stretching degree of freedom.
Embodiment 3
Lifting mechanism 3 in the foregoing description is made up of support 7, positioning and guiding wheel 6, worm drive pair 5, propulsion source 9, cross universal coupling 10.
Propulsion source 9 is in transmission connection with cross universal coupling 10, cross universal coupling 10 is in transmission connection with worm drive pair 5, cross universal coupling 10 is Collapsible structures, worm drive pair 5 is fixed on the support 7, worm drive simultaneously secondary 5 are in transmission connection with the screw mandrel 11 that is fixed in the column 2, support 7 also is fixedly connected with positioning and guiding wheel 6, the guide rail 8 that guiding is arranged in the column 2, positioning and guiding wheel 6 places in the guide rail 8, propulsion source 9 is electrical motors, propulsion source 9 imports power into worm drive pair 5 by telescopic cross universal coupling 10, make worm drive pair 5 do the dipping and heaving of straight line along screw mandrel 11, worm drive secondary 5 drive support 7 and positioning and guiding wheel 6 guide rails 8 along column 2 move, and have realized the lifting of whole lifting mechanism 3.
Telescopic cross universal coupling 10 all is widely used in each field and its structure is not described in detail herein.
Because lifting mechanism and platform are to flexibly connect, and cross orientation problem so eliminated all, thereby have following advantage:
1) production and processing difficulty, field engineering difficulty are reduced greatly, thereby save cost;
2) eliminated owing to cross the resistance of motion that bring the location, reduced the power of lifting motor, energy-conserving action has been arranged;
3) improve the applying working condition of worm drive pairs, improved service life;
4) improve the stationarity of lifting platform, reduced the noise in the lifting platform process.
