Abstract

PURPOSE:To facilitate even the removal of mud blocking a tire in its groove by providing a lift path to be formed in a smooth staircase state and circulating water pipe, providing many injection nozzles in the surface, along a corner part of each staircase. CONSTITUTION:A smooth staircase-shaped lift path 1 is formed toward a water storage pit in its recessed direction. This lift path 1, by forming its kickup surface 1a short further tread surface 1b long, enables a work truck to pass through. A transverse groove 3 is recessed along each staircase-shaped corner part, and a circulating water pipe 4, forming many injection nozzles 5 in the pipe wall surface, is arranged in a semi-sinking state in each transverse groove 3. A washing pump P1 and a mud discharging pump P2 are contained in the water storage pit 2, and connecting a delivery port of the washing pump P1 to the circulating water pipe 4 through a delivery flow pipe 9, mud is removed from a tire surface by water injected from the injection nozzle 5 of the pipe 4.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a cleaning device for cleaning mud from the tires of work vehicles such as trucks used at civil engineering sites.

[Prior art and its problems]

Traditionally, mud from the tires of work vehicles used at civil engineering sites is
Work 4 on the flat section formed below the slope-shaped hoistway.
Cleaning is performed in the normal state with L stopped. However, washing out the highly viscous mud that has gotten stuck in the tires requires a long cleaning process, and often requires manual mud removal.

[Purpose of the invention]

An object of the present invention is to provide a cleaning device f that makes it easy to remove mud that has clogged the tires, and that ensures reliable mud removal in a short time without the need for manual assistance. It is in.

[Structure of the invention]

The tire cleaning device for work vehicles used at civil engineering sites according to the present invention has a hoistway formed in the shape of gentle steps, and a circulating water pipe led out from the discharge port of a cleaning pump. It is arranged horizontally along the corner part of each of the stairs, and has an injection port arranged on the bottom surface of the circulating water pipe.

〔Example〕

In the drawings of the embodiment, 1 is a shaft with a gentle staircase shape, which is lowered by 1 toward the concave direction of the water storage bit 2, and the riser surface 1a of each stair portion is shortened, and the tread surface 1b is lengthened. By forming horizontal grooves 3 to allow passage of work vehicles, and recessed horizontal grooves 3 along the corners of each staircase...
...3, a Fusaki circulating water pipe 4...4 is installed horizontally in a semi-submerged manner, and the circulating water pipe 4...4
No. 1! ! ? Injection ports 5...5 are arranged on the wall surface. The length of the riser surface 1a and the depth of the lateral groove 3 are set so as to protect the circulating water pipe 4 and prevent it from being crushed by tires. 6...6Vi This protector protects the edge of each staircase from the weight and impact of the work vehicle. The upper surface of the water storage pit 2 has a hoistway 1. 1
A roadbed 7 is installed horizontally so as to connect the lower parts between the two, and L-shaped steels 8...8 are attached and fixed at predetermined intervals on the roadbed 7. A cleaning pump P1 and a sludge pump P2 are housed inside the water storage pit 2. The suction port of the cleaning pump P1 is opened in the middle part of the pit 2, and the discharge port is connected to the circulating water pipe 4 through the discharge conduit 9.
・・・・・・Connected to 4. Further, the suction port of the mud removal pump P2 is opened as far down as possible within the pit 2, and the discharge port is connected to a mud removal pipe 1Ot- to lead it out to the outside. In the center of the roadbed 7, there is an inlet 1 leading into the pit 2.
1 has been established.

When a work vehicle such as a truck enters one of the lift MII 51, the cleaning pump P1 is activated by the signal from the detector.
The water in the pit 2 is sucked and the circulating water pipe 4...
Tires are cleaned by spraying from the injection port 5 of No. 4, but since the hoistway l is formed in a step-like manner, the spray gets stuck in the tires due to the vibration effect when the work vehicle descends. This produces the effect of removing the muddy dirt that has settled in, and in combination with the jetting action of the washing water, the mud from the tire surface can be easily removed.

Even when all the work vehicles have passed through the hoistway and reached the horizontal roadbed 7, the L-beams 8 are lowered at predetermined intervals...
- The vibration action of 8 promotes the removal of mud, and when the work vehicle ascends the other lifting NIl, effective mud removal is performed by the jet of washing water and the vibration action. In this way, the work vehicle descends from one hoistway 1 and the horizontal roadbed 7
Reliable mud removal will be performed during the process of ascending from the other hoistway l through the top. And the work vehicle is on the other hoistway.
, the cleaning pump P1 stops operating due to the signal from the detector.

The cleaning water injected from the injection port 5...5 not only cleans the tires but also cleans the hoistway l.
It flows down into the pit 2 from the inlet 11 at the center of the lower part together with the washed-off mud. Therefore, the mud does not accumulate on the treads lb of each staircase, and can be efficiently carried into the pit 2.

The water in the middle part of the pit 2 is reused as washing water, but the mud that has settled in the lower part of the bit 24 is discharged to the outside by the mud removal pump P2. Circulating water pipe 4 installed horizontally along the corner of each staircase...
4 is protected in one direction by the upper surface 1a of the husband 4, and is not crushed by the tires.

[Effects of the Invention J] According to the present invention, the effect of removing mud from the tire surface due to @operation when the work vehicle passes through the stair-shaped hoistway 1,
This, combined with the cleaning water injection action from the injection port 5...5, makes it easy to remove mud from the tire surface, and the cleaning work can be done in a short time, ensuring reliable mud removal without the need for input input. It has the advantage of being carried out. In addition, since the washed mud flows down together with the washing water sprayed from the injection ports 5...5, it does not accumulate on the treads lb of each staircase, and also serves as a cleaner for the hoistway 1. Become. Furthermore, circulation#/
Since the X-vibe 4...4 is installed horizontally at the corner of each staircase, it is protected by the riser surface 1a and is safe because it will not be crushed by the tires.
