Background

In the engineering construction site, a large number of pipeline workpieces often need to be transported, and large-scale transportation equipment often cannot enter the engineering construction site and is often carried by manpower. However, these pipes are generally long, and require two or more persons to cooperate during transportation, which occupies a lot of manpower, and many persons are not easy to coordinate, and the transportation efficiency is not high. Most of the existing pipeline transportation schemes use a two-wheel vehicle with a fixed arc-shaped car hopper, but the car hopper with a fixed shape corresponding to a certain diameter has poor fixing effect on other pipelines with different diameters.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a: the problem of among the prior art artifical transport pipe way occupy the manpower big, unable single transportation is solved, a manpower vehicle of transport pipe way is provided.

In order to realize the purpose, the utility model discloses a technical scheme be:

When a long pipeline is carried purely manually, two or more persons are often required to carry the pipeline at the same time; when the pipeline is transported by the scheme, the left side baffle and the right side baffle clamp the pipeline through the elastic force of the spring and fix the pipeline on the supporting plate, the pipeline is equivalent to the hand of a second person, and the wheels are equivalent to the foot of the second person, so that the pipeline transportation device has the function of replacing the second person; and compared with walking, the wheels are more labor-saving, easier to transport at a higher speed and higher in efficiency.

The side block is arranged on two sides, namely the pipeline axis is parallel to the front and back directions of the two-wheel vehicle during transportation, and compared with the scheme that the pipeline axis is parallel to the left and right directions, the arrangement is stronger in trafficability and more accords with the operation intuition of ordinary people.

Meanwhile, compared with some arc-shaped supporting plate schemes with fixed shapes, the scheme can be suitable for pipelines with different diameters within a certain range because the distance between the left side baffle and the right side baffle is variable; and because bottom plate, left side fender and right side fender still are the plane, take to transport ordinary goods and also can guarantee the face contact like the carton, and can not lead to carton and inside goods impaired because the shape reason can only line contact like fixed arc layer board, consequently when needs, the article kind of transportation is also more. The left and right movement can be realized through various modes such as a slide rail, a linear bearing and the like.

As a preferable scheme of the invention, sliding shafts with axes parallel to the moving directions of the left side baffle and the right side baffle are processed on the left side baffle and the right side baffle; the left side and the right side of the supporting plate are both provided with bulges; the bulge is provided with a sliding hole; the left side baffle is arranged on the corresponding sliding hole through the sliding shaft on the left side baffle; the right side block is arranged on the corresponding sliding hole through the sliding shaft on the right side block. The left side baffle and the right side baffle are installed on the supporting plate through the matching of the hole shaft, and the required translation freedom degree in the left and right directions is reserved. Compared with other schemes such as a slide rail, a screw rod and the like, the scheme has a simple and reliable structure and is more suitable for engineering construction sites with poor working environments; and meanwhile, the cost is lower.

As a preferable aspect of the present invention, the spring is a compression spring; springs are arranged between the bulge and the left side block and between the bulge and the right side block; the spring is sleeved on the sliding shaft. Compare in extension spring, compression spring is small, arranges well, can not lead to the bicycle volume to increase by a wide margin and influence the trafficability characteristic. Meanwhile, because the springs are arranged on the two sides, when the moving distances of the left side baffle and the right side baffle relative to the supporting plate are different, the gravity center of the clamped pipeline deviates to one side of the two-wheel vehicle, the sliding distance of the side baffle which is further away from the center of the two-wheel vehicle is large, and the deformation of the springs is large; the side with large deformation has larger elasticity, so that the side stopper can be pushed to move towards the center of the two-wheel vehicle, and the pipeline is pushed to move towards the center of the two-wheel vehicle; namely, the scheme can automatically center the gravity center of the pipeline left and right; the spring is sleeved on the sliding shaft, so that the elastic force and the movement axis are superposed, the redundant torque is reduced, and a fixing structure of the spring can be omitted.

As a preferable scheme of the present invention, the supporting plate further comprises a lower latch; the left side baffle and the right side baffle also comprise rotatable handles; an upper latch is fixed on the handle; the handle can enable the upper latch and the lower latch to be engaged and disengaged through rotation.

As a preferable scheme of the invention, a handlebar is fixed on one side of the supporting plate; the handlebar is provided with a holding section which is bent downwards at an angle of 30 to 45 degrees relative to a horizontal plane. The handle bar is fixed on one side only, so that the operation of personnel on one side is not hindered by an overlong pipeline; the downwardly curved handlebar is more comfortable to hold.

As a preferable aspect of the present invention, the wheel includes a brake-by-wire device; and a brake handle for controlling the brake-by-wire device is arranged on the handlebar. The braking device gives the braking capability to the scheme so as to deal with the situations of sudden stop, downhill and parking. The brake handle is arranged on the handlebar, so that the operation of personnel is facilitated.

As a preferable scheme of the present invention, the top surface of the supporting plate, the inner side surfaces of the left side stopper and the right side stopper are provided with anti-slip belts. The friction coefficient of the contact surface can be increased by the anti-skid band, so that the pipeline is firmly fixed, and safety accidents caused by accidental falling of the pipeline are prevented.

As the preferable scheme of the invention, the anti-skid belt is a wave-shaped steel plate; the wave extending direction of the anti-skid belt is along the front and back directions of the rickshaw; the surface of the anti-slip belt is covered with a passivation coating. The glass-shaped steel plate covered with a passivation coating such as inorganic zinc-rich paint has the advantages of corrosion resistance, large friction coefficient and more durability compared with a rubber anti-slip belt.

As a preferable aspect of the present invention, a shock absorbing device is connected between the wheel and the hopper. Because the scheme is mainly applied to engineering construction sites, the road surface is often in a bad condition, and when a long pipeline is transported, the small jolt can be amplified at the two ends of the pipeline, accidents are easily caused by unexpected movement or the pipeline is easily damaged; therefore, the damping device is introduced, so that the trafficability can be increased, the road surface impact can be absorbed, and the transportation pipeline is protected.

As a preferable aspect of the present invention, the damping means is a plate spring. Compared with other damping devices, the plate spring is small in longitudinal size, and the gravity center of the vehicle cannot be too high; simple structure, reliable operation and suitability for severe environment of engineering construction site.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

1. use layer board, left side fender and right side fender centre gripping pipeline, transport with the wheel again, be equivalent to introducing the second personnel, thereby use alright reduction personnel to occupy when transporting the pipeline.

2. The left side keeps off and the right side keeps off can the adjustment interval, can both guarantee to stabilize the centre gripping when dealing with the pipeline of different diameter scopes.

3. The wheels are more labor-saving than walking, so that the speed of personnel can be increased conveniently, and the transportation efficiency is improved.

4. Because the shape of the car hopper is still square, when goods outside the transportation pipeline are transported, the goods and the interior of the goods are not easy to be damaged due to line contact caused by the inconformity of the shapes.
