Description

Technical Field

[0001] This utility model relates to the field of slope construction technology, specifically to a sand and gravel transport device for slope protection. Background Technology

[0002] Slope protection by paving with gravel involves spreading large quantities of pebbles, sand, and gravel in a specific gradation and layering pattern along a sloping bank. This increases the density of the soil on the slope, thereby enhancing its resistance to collapse. This method of bank protection on water bodies not only helps stabilize the slope but also provides excellent greening and beautification of the slope surface.

[0003] Currently, for backfilling sand and gravel on slopes with long horizontal distances, the main method is to use cranes for transportation, supplemented by excavators and loaders. However, during on-site construction, due to the different backfilling requirements at different locations and elevations of the slope, cranes cannot accurately transport sand and gravel to the designated locations on the slope. Moreover, large-tonnage cranes are often limited by the construction site and difficult to carry out lifting operations. Furthermore, the cost of operating large-tonnage cranes is high, resulting in high operating costs. Therefore, using cranes is not only inefficient but also has high mechanical costs. Utility Model Content

[0004] To address the problems of the prior art, this utility model provides a sand and gravel transport device for slope protection, which can transport sand and gravel to a designated location on the slope, improving the transport efficiency of sand and gravel, and with low mechanical cost.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sand and gravel transport device for slope protection, comprising a main truss, a sand and gravel transport mechanism mounted on the main truss, a lateral walking mechanism capable of moving the main truss laterally, and a positioning mechanism capable of transporting sand and gravel to a designated location.

[0006] The above structural design enables the transport of sand and gravel to designated locations on the slope, improving the efficiency of sand and gravel transport while keeping mechanical costs low.

[0007] Preferably, the sand and gravel transport mechanism includes a power roller rotatably connected to the lower end of the main truss, a drive motor connected to the power roller, a driven roller rotatably connected to the upper end of the main truss, a support roller rotatably connected to the main truss, and a sand and gravel conveyor belt that is sleeved on the power roller, the driven roller, and the support roller. The drive motor is fixedly connected to the main truss.

[0008] With the above structural design, the motor starts and drives the power roller to rotate. The power roller can drive the driven roller to rotate together through the sand and gravel conveyor belt. The sand and gravel conveyor belt carries the sand and gravel together. The idler roller supports the sand and gravel conveyor belt, thereby conveying the sand and gravel.

[0009] Preferably, the positioning mechanism includes a first sliding rod slidably connected to the main truss, a baffle fixedly connected to the sliding rod, and a fastening bolt passing through the first sliding rod. The main truss has multiple mounting holes that match the fastening bolts, and the lower end of the baffle is in contact with the surface of the sand and gravel conveyor belt.

[0010] With the above structural design, the first sliding rod moves the baffle to the designated position. The baffle blocks the sand and gravel. After the sand and gravel are transported to the baffle position, they will fall along the baffle from both sides of the sand and gravel conveyor belt and finally fall to the designated position of the slope protection.

[0011] Preferably, the two ends of the baffle are folded inward along its centerline to form an inner angle of less than 10 degrees.

[0012] The above structural design makes it easier for the baffles to separate the sand and gravel, which then fall from both sides of the sand and gravel conveyor belt.

[0013] Preferably, a brush strip is fixedly connected to the lower end of the baffle, and the brush strip is in contact with the surface of the sand and gravel conveyor belt.

[0014] With the above structural design, the brush strips fit tightly with the sand and gravel conveyor belt, preventing the baffle from contacting the sand and gravel conveyor belt and thus avoiding the baffle affecting the conveying of the sand and gravel.

[0015] Preferably, both ends of the baffle are fixedly connected to side plates, and the lower surface of the side plates is fixedly connected to a second sliding rod, with a second fixing bolt that matches the mounting hole passing through the second sliding rod.

[0016] With the above structural design, the side plates can help the sand and gravel fall from both sides of the sand and gravel conveyor belt, preventing the sand and gravel from falling into the interior of the device and affecting its operation.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This device can transport sand and gravel to designated locations on the slope, adapting to backfilling needs at different elevations and locations on the slope, improving the efficiency of sand and gravel transportation, and with low mechanical costs. Attached Figure Description

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 This utility model provides a technical solution: a sand and gravel transport device for slope protection, including a main truss 1, a sand and gravel transport mechanism set on the main truss 1, a lateral walking mechanism 6 capable of moving the main truss 1 laterally, and a positioning mechanism capable of transporting sand and gravel to a designated location.

[0024] The main truss 1 is equipped with a transverse traveling mechanism 6 at both the upper and lower ends. The transverse traveling mechanism 6 can carry the main truss 1 to travel laterally. The transverse traveling mechanism 6 is a track-type traveling mechanism. Usually, steel rails need to be laid on the roads on both sides of the slope, and this device can then travel along the steel rails; or the transverse traveling mechanism 6 is a crawler-type traveling mechanism, which makes this device more suitable for the construction environment.

[0025] The sand and gravel transport mechanism includes a power roller 21 rotatably connected to the lower end of the main truss 1, a drive motor 22 driven by the power roller 21, a driven roller 23 rotatably connected to the upper end of the main truss 1, a support roller 24 rotatably connected to the main truss 1, and a sand and gravel conveyor belt 25 sleeved on the power roller 21, driven roller 23, and support roller 24. The drive motor 22 is fixedly connected to the main truss 1. A tension roller 26 for tensioning the sand and gravel conveyor belt 25 is installed on the main truss 1, and the tension roller 26 contacts the inner wall of the sand and gravel conveyor belt 25. The sand and gravel transport mechanism can transport sand and gravel from the lower end to the upper end of the sand and gravel conveyor belt 25.

[0026] The positioning mechanism includes a first sliding rod 31 slidably connected to the main truss 1, a baffle 32 fixedly connected to the sliding rod 31, and a fastening bolt 33 passing through the first sliding rod 31. The main truss 1 has a plurality of mounting holes 34 that match the fastening bolt 33. The lower end of the baffle 32 is in contact with the surface of the sand and gravel conveyor belt 25.

[0027] The two ends of the baffle 32 are folded inward along its centerline to form an inner angle of less than 180 degrees. The size of the inner angle is between 15 degrees and 150 degrees. In this embodiment, the size of the inner angle is 60 degrees. An inner support plate 33 is provided between the two ends of the baffle 32. The left end of the inner support plate 33 is fixedly connected to the left end of the baffle 32, and the right end of the inner support plate 33 is fixedly connected to the right end of the baffle 32.

[0028] The lower end of the baffle 32 is fixedly connected to the brush strip 4, which is in contact with the surface of the sand and gravel conveyor belt 25 and is in close contact with the outer surface of the sand and gravel conveyor belt 25.

[0029] Both ends of the baffle 32 are fixedly connected to the side plate 5. The lower surface of the side plate 5 is fixedly connected to the second sliding rod 51. The second sliding rod 51 is provided with a second fixing bolt 52 that matches the mounting hole 34. The upper end of the side plate 5 is flush with the sand and gravel conveyor belt 25 so that the sand and gravel can fall along the side plate 5.

[0030] Working principle: Steel rails are laid on the roads on both sides of the slope. This device is installed on the steel rails. Then, the operator moves the positioning mechanism. For example, if sand and gravel need to be transported to the middle of the slope, the operator can move the baffle 31 to the middle of the main truss 1. Then, the operator passes the fastening bolt 33 through the first sliding rod 31 and the main truss 1, and then tightens the fastening bolt 33 with a nut. The second fixing bolt 52 is then passed through the second sliding rod 51 and the main truss 1, and then tightened with a nut. Finally, the operator starts the drive motor. Machine 22 and drive roller 21 rotate, which in turn drives the sand and gravel conveyor belt 25 mounted on drive roller 21, driven roller 23 and idler roller 24. The sand and gravel on the sand and gravel conveyor belt 25 are then conveyed. When the sand and gravel are conveyed to baffle 32, they are blocked by baffle 32. The sand and gravel are first separated by baffle 32 to both sides of baffle 32, and then fall from both sides of sand and gravel conveyor belt 25. Finally, the sand and gravel fall along side plate 5. When there is enough sand and gravel in the middle of the slope, the workers start the lateral walking mechanism 6 to move the main truss 1 laterally and continue to convey sand and gravel.
