Abstract
Electric expansion grandstand track driving mechanism, mainly it is made up of the driven pedrail of motor, reductor, drive shaft and the left and right sides, motor via reducer is connected with drive shaft, drive shaft two ends are connected by connecting shaft set and a power transmission shaft respectively, one drive is installed on power transmission shaft, driven pedrail one end is wound on drive, and the driven pedrail other end is connected with electric expansion grandstand support body, and connecting shaft set is mutually connected vertically by two U-shaped joints and forms at contiguous block.Electric expansion of the present utility model grandstand track driving mechanism Multi-stage linked Ceng Chu mechanism, simple in construction, easy to use, use mechanical linkage structure, greatly reduce production cost and the operating cost of electric expansion grandstand drive mechanism, be widely portable to TV broadcast, arenas, stadium, various rally and in-situ match.
Description
Technical field
This utility model relates to sports apparatus technical field, is specifically related to a kind of electric expansion grandstand track driving mechanism.
Background technology
Seeing table apparatus, for stadiums owner, change place purposes seems the most critically important the most at any time,
This makes one to invest huge gymnasium can undertake different types of match and other business activity, thus is greatly improved
Its utilization rate, for the multi-functional usage trend of sports buildings, movable stand system is arisen at the historic moment and (domestic is also called flexible grandstand
Or move grandstand).Movable stand major advantage is motility, safety and the high value of its height.Original many merits
Concept can be changed and can meet the movement needs of different team, open road for the most challenging public set, make limited
Unlimited application is made in space, brings novel concept for venue seat.
Existing seeing that table apparatus has multiple structure mostly, it is all to be entered by hydraulic drive mechanism that every layer of grandstand stretches out structure
Row cutting, hydraulic drive mechanism structure is complicated, and operating cost is high, takes up room big, and manufacturing cost is high, keeps in repair the most tired
Difficulty, have impact on the long-period stable operation seeing table apparatus.
Utility model content
The deficiency that this utility model exists for prior art, it is provided that a kind of electric expansion grandstand track driving mechanism.
This utility model solves its technical problem and be the technical scheme is that
A kind of electric expansion grandstand track driving mechanism, mainly by the transmission of motor, reductor, drive shaft and the left and right sides
Crawler belt forms, and motor via reducer is connected with drive shaft, and drive shaft two ends are connected by connecting shaft set and a power transmission shaft respectively,
Installing a drive on power transmission shaft, driven pedrail one end is wound on drive, and the driven pedrail other end and electric expansion see stand
Body is connected, and connecting shaft set is mutually connected vertically by two U-shaped joints and forms at contiguous block.
Above-mentioned reductor top arranges and is used for and the fixed disk being connected bottom electric expansion grandstand support body, and power transmission shaft is arranged
It is used for and the fixed hub being connected bottom electric expansion grandstand support body.
Operation principle of the present utility model is: start motor, and motor via reducer drives drive shaft turns, and drive shaft is led to
About crossing, two connecting shaft sets drive drive axis, and the drive on power transmission shaft drives driven pedrail to rotate, thus realizes electronic
Flexible grandstand support body moves.
Electric expansion of the present utility model grandstand track driving mechanism Multi-stage linked Ceng Chu mechanism, simple in construction, use
Convenient, use mechanical linkage structure, greatly reduce production cost and the operating cost of electric expansion grandstand drive mechanism, can be wide
General it is applicable to TV broadcast, arenas, stadium, various rally and in-situ match.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of this utility model connecting shaft set.
1 motor in figure, 2 reductors, 3 drive shafts, 4 connecting shaft sets, 5 power transmission shafts, 6 drives, 7 driven pedrails, 8 fixed disks, 9
Fixed hub, 41U oblique crank Z joint, 42 contiguous blocks.
Detailed description of the invention
As depicted in figs. 1 and 2: a kind of electric expansion grandstand track driving mechanism, mainly by motor 1, reductor 2, driving
The driven pedrail 7 of axle 3 and the left and right sides forms, and motor 1 is connected with drive shaft 3 by reductor 2, and drive shaft 3 two ends lead to respectively
Crossing connecting shaft set 4 to be connected with a power transmission shaft 5, power transmission shaft 5 is installed a drive 6, driven pedrail 7 one end is wound on drive 6,
Driven pedrail 7 other end is connected with electric expansion grandstand support body, and connecting shaft set 4 is mutually connected vertically even by two U-shaped joints 41
Connecing block 42 to form, reductor 2 top arranges and is used for and the fixed disk 8 being connected bottom electric expansion grandstand support body, and power transmission shaft 5 sets
Put for the fixed hub 9 being connected bottom electric expansion grandstand support body.
Operation principle of the present utility model is: start motor, and motor via reducer drives drive shaft turns, and drive shaft is led to
About crossing, two connecting shaft sets drive drive axis, and the drive on power transmission shaft drives driven pedrail to rotate, thus realizes electronic
Flexible grandstand support body moves.
Claims (2)
