Abstract

The utility model discloses a traction type mobile car. A hydraulic drum of a traction mechanism (1) of the traction type mobile car winds a first and a second steel wire ropes (3, 3'), wherein one end of the first steel wire rope (3) is connected with one side of the car (2) through a first reversing pulley (5); and one end of the second steel wire rope (3') is connected with the other side of the car (2) through a second reversing pulley (5'). A hydraulic drum coil of the traction mechanism (1) rotates in forward/reverse direction, so that one end of the first steel wire rope (3) is folded and one end of the second steel wire rope (3') is released; therefore, the traction car (2) goes forward or backward on a rail (6). The traction type mobile car has the advantages of adopting simple structure, being stable and reliable to drive, having low failure rate and being convenient to maintain and the like; the traction type mobile car does not skid easily when being started and braked during the operation; steel wheels are not easy to deviate off the rail; and the whole height is reduced.

Description

Towed travelling car

Technical field

The utility model relates to a kind of Beam transportation vehicle travelling car of new structure, particularly relates to a kind of towed travelling car.

Background technology

In present high ferro construction equipment, unit in charge of construction generally all adopts Beam transportation vehicle to transport the beam operation, it is used for and the travelling car of bridge formation machine coordinating operation adopts sprocket wheel chain drive and motor reducer directly to drive two kinds of forms usually, these two kinds of type of drive exist weak point to show the car load excessive height, along with country builds high-speed railway energetically, the construction of railways in the many tunnels of regional many bridges, southwest is crossed tunneling operation to Beam transportation vehicle is made troubles, thereby the weak point of above two kinds of drive forms is more obvious.

In the prior art, the type of drive that mainly adopts of the travelling car of Beam transportation vehicle has the motor-driven reductor to drive the sprocket wheel chain drive and the steel wheel that directly is connected by motor reducer in the car frame drives dual mode.The motor-driven reductor drives sprocket wheel chain type of drive (see figure 2), it is the vehicle structure that available technology adopting motor-driven reductor drives sprocket wheel chain drive scheme, in this structure, drive car traction vehicle frame, rely on chain dolly to be moved forward and backward to the traction drives wheel of vehicle frame, this type of drive dolly is difficult for skidding, but overall dimensions is bigger, highly is difficult for reducing.Motor reducer directly is connected type of drive (see figure 3) in the car frame, it is the structure that the available technology adopting motor reducer directly is connected steel wheel drive scheme in the car frame, in this kind structure, frictional force makes trolley travelling between drive car driving trolley wheel dependence wheel and the track, this type of drive is simply direct, easy for installation, drive reliably, but have many weak points, promptly because adhesion of wheels is little, whole unbalance stress, play braking and easily skid, dolly location inaccuracy is unfavorable for using under the outdoor climate conditions of rainy or easy frost, overall dimensions is bigger, highly is difficult for reducing.

Summary of the invention

Easily skid, locate inaccuracy, dolly overall dimensions for a braking that overcomes the prior art existence and be difficult for deficiencies such as reduction greatly and highly, the utility model provides a kind of towed travelling car, this towed travelling car overall dimensions is little, highly low, is specially adapted to pack in the high ferro construction Beam transportation vehicle and the bridge formation machine coordinating operation of concrete box girder.

The technical scheme that its technical problem that solves the utility model adopts is: described haulage gear comprises fluid pressure type reel and wire rope, the fluid pressure type reel of haulage gear twines first, second wire rope, wherein, one end of first wire rope is connected in a side of dolly by first angle pulley, and an end of second wire rope is connected in the opposite side of dolly by second angle pulley.The fluid pressure type reel of haulage gear is installed on Beam transportation vehicle or other parts.The fluid pressure type reel volume of haulage gear is done forward and reverse rotation, the end traction other end of first, second wire rope is discharged, thereby trailer wagon advances or retreats in orbit.

The utility model can be used as the travelling car that transports on the concrete box girder Beam transportation vehicle, and the rotating of described travelling car by the fluid pressure type reel realize advancing of dolly or retreat, and satisfies and the needs of bridge formation machine coordinating operation.

The beneficial effects of the utility model are: whole height reduces, and starting during operation, braking are difficult for skidding, and steel wheel is difficult for sideslip and agree rail, and is simple in structure, and driving is steadily reliable, and fault rate is low, and is easy to maintenance.

In accompanying drawing 1,1. haulage gear, 2. dolly, 3. first wire rope, 3 '. second wire rope, 4. dolly wheel, 5. first angle pulley, 5 '. second angle pulley, 6. track.

The specific embodiment

Further describe the technical solution of the utility model below in conjunction with embodiment.

Fig. 1 is the structural representation of the towed travelling car of present embodiment, this towed travelling car comprises haulage gear 1, first, second wire rope (3,3 '), the fluid pressure type reel of haulage gear 1 is installed on Beam transportation vehicle or other parts, first, second wire rope (3,3 ') is separately fixed at the both sides of dolly 2, be wrapped on the fluid pressure type reel then respectively, forward and reverse rotation by the fluid pressure type reel makes an end of first, second wire rope (3,3 ') pack up the other end to discharge, and dolly wheel 4 is rotated finish dolly 2 to advance on track 6 or retreats.

Usually, the utility model is specially adapted to high ferro and packs on the Beam transportation vehicle of concrete box girder, the machine coordinating operation of finishing and build bridge.

Claims

1. towed travelling car, comprise dolly (2) and track (6), it is characterized in that: the fluid pressure type reel of haulage gear (1) twines first, second wire rope (3,3 '), wherein, one end of first wire rope (3) is connected in a side of dolly (2) by first angle pulley (5), and an end of second wire rope (3 ') is connected in the opposite side of dolly (2) by second angle pulley (5 ').

2. towed travelling car according to claim 1, it is characterized in that: the fluid pressure type reel volume of haulage gear (1) is done forward and reverse rotation, an end that makes an end of first wire rope (3) pack up second wire rope (3 ') discharges, thereby trailer wagon (2) advances on track (6) or retreats.
