[description of drawings]
Accompanying drawing 1 is the structural representation of a kind of scalable lift platform that dwindles of the utility model.。
[specific embodiment]
Below in conjunction with embodiment and with reference to accompanying drawing the utility model is further described.
The Reference numeral and the ingredient that relate in the accompanying drawing are as follows:
1. fixed platform 2. scaling platforms
3. support 31. main structure supports
32. auxiliary structure support 33. branch head screws
311. water jacket steel pipe 312. inside groove steel pipes
321. round steel pipe in the outer round steel pipe 322.
Please refer to accompanying drawing 1, accompanying drawing 1 is the structural representation of a kind of scalable lift platform that dwindles of the utility model.Described lift platform is made up of fixed platform 1, scaling platform 2 and support 3.Described fixed platform 1 is circular steel plate, and described support 3 is welded on below the fixed platform 1.Described support 3 is made up of 8 main structure supports 31 and 8 auxiliary structure supports 32, main structure support 31 and auxiliary structure support 32 cross-distribution, from the center of circle of fixed platform 1 to around disperse, with whole circumference 16 five equilibriums.Described main structure support 31 is made up of water jacket steel pipe 311 and inside groove steel pipe 312, described water jacket steel pipe 311 is that a cross section is rectangular steel pipe, place by two 12# channel-section steel tile verticallies, and carry out Two bors d's oeuveres and be welded, described inside groove steel pipe 312 also is that cross section is rectangular steel pipe, be welded by two 8# channel-section steel Two bors d's oeuveres, described inside groove steel pipe 312 is inserted in the middle cavity of water jacket steel pipe 311, can extend and shorten, inside groove steel pipe 312 and water jacket steel pipe 311 are undertaken fastening by branch head screw 33.Described auxiliary structure support 32 is made up of outer round steel pipe 321 and interior round steel pipe 322, described outer round steel pipe 321 is external diameter 108mm, the round steel pipe of thickness of pipe wall 5mm, round steel pipe 322 is external diameter 89mm in described, the round steel pipe of thickness of pipe wall 5mm, round steel pipe 322 is inserted in the middle cavity of outer round steel pipe 321 in described, can extend and shorten, interior round steel pipe 322 and outer round steel pipe 321 are undertaken fastening by branch head screw 33, it mainly is when reinforcing platform that described auxiliary structure support 32 is selected round steel for use, alleviates the weight of lift platform.Flexible by inside groove steel pipe 312 and interior round steel pipe 322 can be realized the expansion of lift platform and dwindle.Described scaling platform 2 is to adopt the checkered steel plate of thickness 3mm to carry out prefabricated according to platform angle, length and width, described inside groove steel pipe 312 and interior round steel pipe 322 are stretched out water jacket steel pipe 311 and outer round steel pipe 321, and with branch head screw 33 fixing after, prefabricated scaling platform 2 is laid on fixed platform 1 outer ring, can realizes the expansion of lift platform.
