Disclosure of Invention

In order to overcome the defects of the working state of the pipe coiling device in the prior art, an improved pipe coiling device water pipe vehicle with a buffering pipeline window is produced. The technical scheme for solving the problem of locking at any position is various, and mainly aims to improve a crank pin of the position lock; yet another aspect is to improve the racker so as to prevent too rapid retraction of the pipeline.

Further, in order to overcome the disadvantages of the prior art of the pipe winding machine, an improvement of the damper device has been made, and a position lock mechanism of a crank pin (10) type which runs along inner and outer cam grooves of the bottom surface of the damper box housing (3) is adopted, so that it is desired to make the slow retraction damper and the lock device of an arbitrary position more reliable.

Position lock device by turning handle round pin (10), establish the interior outer cam groove that has far and near many control points along the planar of the bottom surface of damping box shell (3), damping carousel, damping lid and pinion constitute, its bright spot lies in: the crank pin shaft (30) is vertical to the transverse shaft (32), the long shaft (33) is also vertical to the transverse shaft (32), and the crank pin shaft (30) is parallel and opposite to the long shaft (33); the crank pin shaft (30) is movably inserted into the inner cam groove and the outer cam groove, the long shaft (33) is movably inserted into the damping rotating disc, and the long shaft (33) is longer than the crank pin shaft (30), is reliable when being longer, and is locked and runs forwards and backwards; the bottom surface of the box shell (3) is also provided with an observation hole (3a) and an observation hole (3 b); the bottom surface of the damping box shell (3) is provided with a convex part (3c), a convex part (3d) and a locking convex part (3 e); when an operator pulls the pipeline, the upper large disc, the main wheel, the pipe joint and the lower disc rotate relative to the outer shell because the pipe joint is assembled on the main wheel, the pipeline is installed on the pipe joint and wound on the main wheel, the main wheel and the lower disc are fixedly connected into a whole through screws, and the pipe joint is movably sleeved and inserted on a smooth outer shaft of the central large pipe of the lower shell in a rotating way through the central large pipe shaft of the lower disc; when the pipeline is pulled out, the main wheel (14) drives the pinion (9) to enable the damping turntable to drive the crank pin shaft (30) of the crank pin (10) to run along the inner groove on the bottom surface of the damping box shell (3); and drives the damping rotary table of the damping box shell (3) assembled on the main wheel (14); when the pulling is stopped, the crank handle pin shaft (30) can be locked at the locking convex part (3e) due to the reaction of the spring; the point is pulled again and the pipeline is loosened, the crank pin shaft (30) is unlocked along the outer ring groove, and the hose or the cable is automatically rewound under the reaction force of the spring. However, contrary to the above, the position lock is usable, and sometimes it is not known how failure occurs, which may be a problem of pre-balancing of the crank pin, or jamming due to rolling friction of the crank pin shaft, and the spiral of the inner and outer cam grooves having curvature away from the center of the circle and tangent angle should be adapted to some function curve of higher mathematics. In addition, the pipeline (113) and the blocking ball (95) are matched with a pipe arranging handle (107) of the pipe arranging device without tacit, and the brake failure and the pipe arranging disorder are caused when the pipe arranging device retracts too fast; and solving the occasional failure is an old and difficult problem. To this end, improved position locks and rackers for pipeline winders, in particular rolling sleeve balanced position locks for pipe winders and rolling ball balanced position locks for pipe winders, have been created. Yet another problem is that the pipeline is not long enough to be produced and a long distance hydromotor driven trolly with road wheels is required, for this reason, on the basis of the position lock and the pipe arranger of the improved pipeline winder, especially the long distance hydromotor walking wheel hose car hose reel and hydrokinetic walking wide spray hose car and hydrokinetic walking logarithmic spiral groove pipe reel improved according to the position lock of the inner and outer cam grooves of the hose reel are produced.

The pre-balance of the crank pin is probably a problem, while the technical innovation is solved by groping for many times, and the key is to arrange a positive and negative torsion spring on the crank pin. The key is to balance the position lock by using the rolling ball head. Still another problem is that the pipeline is not long enough and long distance water pipe vehicle with running wheels driven by water motor is needed in production; the water-driven walking poking hand slow retraction pipe coiling device adopts a poking hand arrangement scheme on a pipe arranging device of the pipe coiling device to seek slow retraction; therefore, on the basis of an improved position lock of a pipeline winder and a pipe arranging device, in particular on the basis of a long-distance pipe winder with a water motor walking wheel water pipe vehicle and a water motor walking and poking hand slow retraction pipe winder which are improved according to the position lock of an inner cam groove and an outer cam groove of a spiral pipe of the pipe winder, the pipe winder water pipe vehicle with a buffering pipeline window is produced.
