Abstract
The utility model discloses a chain transmission mechanism in a train examination trolley. The chain transmission mechanism comprises a plurality of sections of U-shaped grooves, a chain, a track, a chain wheel, a chain wheel seat and magnetic columns. The chain penetrates through the sections of U-shaped grooves, the two ends of the chain are fixedly arranged at the two ends of the track respectively, one side of the chain wheel is connected with the chain, a hole is formed in the center of the chain wheel, a boss is formed in the center of the chain wheel seat, holes are formed in the circumferential direction of the chain wheel seat, the magnetic columns are inserted in the holes, the chain wheel seat is fixed on a transmission mechanism of the train examination trolley, the chain wheel seat is connected with the chain wheel through magnetic force of the magnetic columns, and the boss on the chain wheel seat is matched with a hole in the chain wheel. Horizontal movement of the train examination trolley is achieved through chain transmission, elastic sliding and slipping phenomenon does not exist, the trolley can operate more stably, the requirement for environment is not high, the chain transmission mechanism can be applied to the bad environment like high temperature and dense dust, and is suitable for long-distance transmission, in addition, chain transmission is more reliable, and the chain wheel is convenient to mount and dismount.
Description
Technical field
The utility model relates to a kind of for being listed as the chain drive of inspection dolly.
Background technology
In existing row inspection dolly, by the friction force between roller and track, realize the horizontal motion of row inspection dolly, easily cause overload to skid, when occurring inclement weather and environment, or the distortion of track itself, resistance between track and roller is strengthened, and row inspection dolly is prone to the situation of skidding and cannot advance in original place.
Summary of the invention
The purpose of this utility model is in order to address the above problem, and proposes a kind of for being listed as the chain drive of inspection dolly.
For being listed as a chain drive for inspection dolly, it is characterized in that, comprise some sections of U-shaped grooves, chain, track, sprocket wheel, chain pulley seat, magnetic post;
U-shaped groove is by chain upper mounting plate, mounting screw, chain lower installation board forms, one end of chain upper mounting plate and one end of lower installation board fixed installation are in orbit, the other end of chain upper mounting plate and the other end of lower installation board form U-shaped groove, chain is through some sections of U-shaped grooves, two ends are separately fixed at track two ends, one side of sprocket wheel connects chain, centre of sprocket is provided with hole, chain pulley seat center is provided with boss, circumferencial direction is provided with hole, in hole, insert magnetic post, chain pulley seat is fixed on the transmission device of row inspection dolly, chain pulley seat is connected with sprocket wheel by the magnetic force of magnetic post, the boss of chain pulley seat coordinates with the hole of sprocket wheel.
The utility model has the advantage of:
Chain gear of the present utility model realizes the horizontal motion of row inspection dolly, nonelastic slip and skidding, trolley travelling is more steady, not high to environmental requirement, can be used for the comparison rugged environment that high temperature, dust are larger etc., and be applicable to longer-distance transmission, and in the utility model, chain gear is more reliable in addition, and sprocket wheel removes and installs conveniently.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The utility model be a kind of for be listed as inspection dolly chain drive as shown in Figure 1, comprise some sections of U-shaped grooves, chain 2, track 3, sprocket wheel 6, chain pulley seat 7, magnetic post 8.
U-shaped groove is comprised of chain upper mounting plate 1, mounting screw 4, chain lower installation board 5, one end of one end of chain upper mounting plate 1 and lower installation board 5 is fixedly mounted on track 3 by mounting screw 4, the other end of the other end of chain upper mounting plate 1 and lower installation board 5 forms U-shaped groove, some sections of U-shaped grooves divide multistage to be fixed on track 3, are convenient to safeguard.
Chain 2 is through some sections of U-shaped grooves, two ends are separately fixed at track 3 two ends, in the utility model, chain 2 two ends are separately fixed at track 3 two ends, in whole transmission process, the relative position of chain 2 is constant, different from other chain gears, in prior art, be generally to be provided with and between principal and subordinate wheel, use chain gear.
One side of sprocket wheel 6 connects chain 2, and sprocket wheel 6 centers are provided with positive hexagonal hole, and sprocket wheel 6 can move along chain 2;
As shown in Figure 2, center is provided with hexagon boss to chain pulley seat 7, and circumferencial direction is provided with 8 holes, and 8 magnetic posts 8 are inserted respectively in the inside, hole;
Described chain upper mounting plate 1, chain lower installation board 5 form U-shaped protective trough, and U-shaped protective trough plays rest and protective action to chain 2, is embodied in:
(1) U-shaped protective trough protection chain 2 is avoided foreign impacts, can also stop the invasion and attack of extraneous a large amount of dust and erosion etc.
(2) U-shaped protective trough has the effect of holder chain, and chain 2 positions are fixed, degree of tightness appropriateness; effectively protection chain 2 can not rupture and become flexible because of the unexpected startup of row inspection dolly; also prevent that sprocket wheel 6 and chain 2 from departing from, make row inspection moving of car steady, the reliability of operation of raising.
Described sprocket wheel 6 is connected with chain pulley seat 7 by magnetic post 8, sprocket wheel 6 easy installation and removals, the positive six side's boss in chain pulley seat 7 centers positive hexagonal hole corresponding to sprocket wheel 6 centers coordinates, conduction moment of torsion, vertical direction relies on the magnetic force of magnetic post 8 to connect, and installing/dismounting can be realized without other instruments.
