Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a tunnel mud cleaning vehicle. Background Art

[0002] During tunnel construction, it is necessary to clean the accumulated mud on the tunnel floor. During the cleaning process, a mud cleaning vehicle with a bucket is generally used to scoop up the accumulated mud first and then load it into the mud loading vehicle. The mud cleaning vehicle is generally replaced by a forklift. When unloading the mud, the bucket needs to be turned over by a large angle. In order to ensure the large-angle turning of its bucket, the forklift is provided with a long arm and has a large volume, which is not suitable for the relatively narrow construction environment in the tunnel.

[0003] To ensure the width of the working surface, the bucket is generally as wide as possible, and due to the limitation of the tunnel space, the mud loading vehicle selects a bucket with a smaller width. During the unloading process, the bucket turns over, and the accumulated mud is discharged along the relatively wide shovel opening and is difficult to enter the bucket with a smaller width. It is necessary to continuously adjust the angle, which is cumbersome to operate and reduces the construction progress. Content of the Utility Model

[0004] The purpose of the utility model is to provide a tunnel mud cleaning vehicle, which is suitable for the relatively narrow construction environment in the tunnel, does not require a large-angle turning of the bucket when unloading the mud, and at the same time reduces the width of the mud discharge, which is beneficial to discharging into the bucket and does not require excessive adjustment of the bucket angle.

[0034] For a clearer description of the specific structural composition of the tunnel mud cleaning vehicle, in combination with the attached Figure 1-8 Describe this embodiment:

[0035] As Figure 1 and Figure 2 shown, a tunnel mud cleaning vehicle includes a vehicle body 1 and a bucket at the head of the vehicle body 1. The bucket includes a bottom surface 2. A shovel opening is formed at the front side of the bottom surface 2, and side and rear baffles 3 are provided on other sides. The entire bottom surface 2 is concave-arc-shaped in the cross-section in the width direction. The bucket is divided into two independent left buckets 4 and right buckets 5 along the dividing surface passing through the arc bottom of the bottom surface 2;

[0036] The bucket adopts a left-right split structure. When shoveling mud, it closes as Figure 5 shown, and opens as Figure 6 shown. The accumulated mud falls along the joint of the left bucket 4 and the right bucket 5. The width of this joint is smaller than that of the shovel opening, and the falling mud is more concentrated, which is convenient for accurately falling into the trolley. The bottom surface of the bucket is arc-shaped and can fit the ground of the tunnel, with high mud shoveling efficiency. At the same time, the joint of the left bucket 4 and the right bucket 5 is at the arc bottom. When the two are opened, the accumulated mud can slide out under the action of gravity, and there is no need to flip the bucket to unload the mud.

[0037] Refer to Figure 7 , a seal 6 is provided at the dividing place of the bottom surface 2. For mud with a large water content, it can prevent excessive seepage of muddy water from the joint during the mud shoveling process. Specifically, the seal 6 includes a rubber pressing plate 601 and a screw 602. Accommodating grooves are respectively provided on the bottom surface 2 on both sides of the dividing place. The rubber pressing plate 601 is fixed in the accommodating groove through the screw 602. When the left bucket 4 and the right bucket 5 are closed, the two rubber pressing plates 601 are in contact without gaps.

The lifting seat 8 is rotatably connected to one end of an inclination adjustment hydraulic cylinder 11. The other end of the inclination adjustment hydraulic cylinder 11 is rotatably connected to the upper end of the back surface of the slide rail 9. The inclination adjustment hydraulic cylinder 11 is used to adjust the inclination of the slide rail 9 and the entire bucket. When shoveling mud, the cylinder arm of the inclination adjustment hydraulic cylinder 11 extends outwards, making the height of one side of the shovel opening lower, which is beneficial for fitting the ground and shoveling up the accumulated mud;

[0042] Refer to Figure 3 and Figure 4 As shown in FIGS. and, the opening and closing mechanism includes two sliders 12 arranged in the chute of the slide rail 9. The two sliders 12 are respectively fixedly connected to the left bucket 4 and the right bucket 5. Two transverse hydraulic cylinders 13 are fixed on the slide rail 9. The cylinder arms of the two transverse hydraulic cylinders 13 are respectively fixedly connected to the left bucket 4 and the right bucket 5. The transverse hydraulic cylinders 13 are used to drive the sliders 12 and the corresponding left bucket 4 / right bucket 5 to move along the slide rail, so as to open or close the left bucket 4 and the right bucket 5. To reduce the friction when the slider 12 slides, a pulley 14 that is in rolling contact with the slide rail 9 is provided on the slider 12.

[0043] Refer to Figure 2 and Figure 8 As shown in FIGS. and, the vehicle body 1 is specifically a conventional engineering vehicle with power. A trolley 15 is hung on the vehicle body 1. One side of the trolley is provided with an open mouth for loading and unloading materials, and the size of the other side away from the open mouth is reduced. Two wheel frames 17 are fixed to the bottom of the trolley 15 near the open mouth. One end of the trolley 15 away from the open mouth is suspended. The wheel frames 17 are in an inverted L shape in the vertical plane and in an eight shape in the horizontal plane. Travel wheels 16 are arranged at the bottom of the wheel frames 17. The travel wheels 16 on the two wheel frames 17 are also in an eight shape in the vertical plane. A plurality of trolleys are connected in sequence by steel wires 18. A plurality of trolleys can be nested together. When nesting the trolleys, the end of the nested trolley away from the open mouth slides into the open mouth of the adjacent trolley, and the two rows of travel wheels 16 of the nested trolley are located between the two rows of travel wheels 16 of the adjacent trolley. When in use, a plurality of trolleys are pulled out and unfolded, and a ton bag is put on the trolley 15 to be used for loading mud. The trolley 15 can be pulled into the tunnel by the vehicle body 1, and after being filled with mud, it can be pulled out of the tunnel by other power equipment.
