Rail transport small car
Technical field
The present invention relates to storage and transportation means, particularly a kind of rail transport small car of storing and transporting of being used to.
Background technology
At present, during fortune dress manually is difficult to carry in small space article, generally adopt small rail car to solve problem between article turnover storage.At first the article of required transportation are fixed on the travelling bogie, travelling bogie relies between track turnover storage then.But because the space is narrow and small, people or instrument inconvenience or can't movable and work between storage cause small rail car to be difficult to fix.Fixing of this type of small rail car generally adopted or multiple spot fixed form at 4 at present.These fixed forms are complicated and be not easy loading and unloading, particularly for fixing dolly front end, because of the space narrow and small, and will be in confined space two side hole (door or window) so that fixingly reach operation such as loading and unloading.Like this with regard to make the space the air-tightness variation and can not satisfy the place that some is had relatively high expectations to air-tightness.Also a kind of situation increases confined space exactly making things convenient for people or tool operation, but space availability ratio will diminish like this.
Summary of the invention
Technical matters to be solved by this invention is: a kind of rail transport small car is provided, need not the people and enter and just can realize the fixing of rail transport small car between storage, and can realize the storage and the transportation of article in the narrow and small confined space that track is arranged.
The technical solution adopted for the present invention to solve the technical problems is: be provided with set of wheels, underframe and anchor fitting, anchor fitting comprises underframe latch assembly, side locking piece and goods catch gear.
The underframe latch assembly: two covers are arranged, and every cover comprises locking arm and locking bed.The upper and lower side of locking arm respectively has a hollow reel, and wherein, the lower end reel also can be rotated around this bolt in the groove of locking bed by bolted connection; During locking, pass the hole of upper end reel and the hole of left crossbeam, and lock underframe by fastening nut by bolt.
Underframe is formed by left crossbeam, right crossbeam with two side bars of their ends welding, and is provided with the channel crossbar that welds with side bar at two side bars and the place of linking, saddle assembly lower end; Left side crossbeam has the bolt hole of two groups of fixed frame latch assemblies.
Locking bed is by in being bolted between storage.
Side locking piece: have two, be welded on the both sides of left crossbeam; The side locking piece has tapped bore, is tightened between storage on the both sides to prevent the dolly play by bolt, is provided with black nut simultaneously.
The goods catch gear: comprise saddle assembly and the goods locking lever that links of upper saddle seat top middle portion with it, the left end of this locking lever is provided with two goods locking heads, and it is by nut locking.
The present invention compares with prior art, has following major advantage:
One. simple in structure, dependable performance, ratio of light weight to loading capacity is up to 0.075 (ratio of light weight to loading capacity is the ratio of dead weight of vehicle and vehicle load).
They are two years old. and simple to operate, use, easy to maintenance.When article are installed, only need article are fixed on the saddle, locking saddle locking lever gets final product; Utilizing the transition rail to get final product a people is transported to article between storage, utilize underframe front end automatic centring device, make center between dolly underframe front end automatic centering storage, and dolly front end upper and lower, left and right, the first five direction are fixed, lock the underframe latching device again, can make whole cart stationary.Coexist and two groups of side locking pieces are housed on the both sides of underframe left side crossbeam, and the two sides is adjacent between storage, is used to prevent whole dolly play.
They are three years old. locking mode advanced person, reliable.Only depend on two latching devices of a locking head and underframe rear end of underframe front end can finish the fixing of whole dolly.The locking head of front end is the evagination pyramidal structure with automatic centering, and when dolly entered between storage, a locking bed that can and be installed in the indent between storage that locks of evagination was close to.Can fix by the jam nut of fastening rear end then.In the locking process, the people need not enter between storage can finish locking operation.Simultaneously, only need unclamp two groups of underframe latching devices of underframe rear end when removing stage makeup and costume, can the transition rail transport goods out between storage outside.
