Description

Technical Field

[0001] The utility model relates to the technical field of soil cleaning devices, in particular to a soil cleaning device for a groove of a steel sheet pile. Background Art

[0002] When burying large thermal pipelines, first drive the steel sheet piles on both sides vertically into the ground, then cut grooves between the two steel sheet piles, and bury the lower ends of the steel sheet piles on the lower side of the grooves. After cutting the grooves, the soil in the grooves on the steel sheet piles needs to be cleaned to prevent it from falling and injuring workers during the subsequent installation of the thermal pipelines.

[0003] A steel sheet pile quick cleaning device in the prior art (publication number: CN216225626U) uses a transmission drive device to drive the force transmission rod to generate downward force to drive the shovel to work. Compared with manual shoveling or water gun spraying, the efficiency is greatly improved, but it still has the following disadvantages:

[0004] 1. The cleaned soil often falls into the foundation of the pipeline groove in the form of lumps, which is not conducive to the subsequent personnel to carry out operations in the pipeline pit. Cleaning and transporting it out of the tunnel alone consumes manpower and financial resources. Therefore, it is urgent to design a steel sheet pile groove soil cleaning device that can shovel and crush the soil at the same time;

[0005] 2. When cleaning the soil, the equipment can only clean one side of the pipe groove at a time, which is not conducive to further improving the construction efficiency. Therefore, it is urgent to design a soil cleaning device that can clean the steel sheet piles on both sides at the same time. Utility Model Content

[0022] The following is a detailed description of a soil cleaning device for a steel sheet pile groove according to the present invention with reference to the accompanying drawings of the specification.

[0023] See also Figure 1-4 The utility model provides a technical solution: a soil cleaning device for a steel sheet pile groove, comprising a trolley 1, a shoveling mechanism, an equipment box 7, a slide 8, a rack 10, a screw 11, a motor 12, an adjustment support frame 13 and a driving mechanism. The top of the trolley 1 is provided with an equipment box 7, an internal cavity of the equipment box 7, and corresponding two sides of the equipment box 7 are respectively provided with a shoveling mechanism, and corresponding two sides of the equipment box are respectively provided with a slide 8, a square slot hole 9 and a rack 10, a screw 11 is provided at the center of the inner cavity of the equipment box 7, the lower end of the screw 11 is connected to the output shaft of the motor 12, one end of the shoveling mechanism is threadedly connected to the screw 11, and a driving mechanism is provided on one side of the shoveling mechanism, the gear of the driving mechanism is meshed with the rack 10 on the side wall of the equipment box, the motor 12 is arranged on the upper part of the adjustment support frame 13, the bottom of the adjustment support frame 13 is connected to the trolley 1, and the top of the adjustment support frame 13 is connected to the bottom of the equipment box 7. The shoveling mechanism includes a shovel blade 3, a fender 4, a connecting bracket 5 and a soil crushing roller 6. The shovel blade 3 is arranged at the lower part of the fender 4. The connecting bracket 5 is in a Y-shaped structure. The fender 4 is movably connected to the lower part of the forked end of the connecting bracket 5. The other end of the connecting bracket 5 is threadedly connected to the screw rod 11. The soil crushing roller 6 is rotatably installed at the bottom of the connecting bracket 5. The rotation of the screw rod 11 drives the shoveling mechanism to move up and down, and the up and down movement of the shoveling mechanism drives the rotation of the driving mechanism.

[0024] After the shovel blade 3 shovels the soil, it slides along the fender 4 to the top of the soil crushing roller 6 and falls down. After being broken up by the rotating soil crushing roller 6, it falls into the foundation of the pipeline groove, thus avoiding the caking of soil shoveled off in the pipeline groove affecting subsequent construction and improving the practicability of the equipment. At the same time, the two sets of soil shoveling mechanisms work synchronously, which can clean the steel sheet piles on the two opposite sides at the same time, thus improving the soil cleaning efficiency.

[0025] The cross section of the blade 3 is in the shape of a "J", which is more suitable for the groove of the steel sheet pile, and blades 3 of different structures can be matched according to the type of the steel sheet pile. The bottom of the mud guard 4 is in an arc structure, and the mud guard 4 is movably connected to the connecting bracket 5. By adjusting the installation position of the mud guard 4, the equipment can better adapt to pipeline grooves of different widths, so that the two blades 3 can better fit the steel sheet pile.

[0026] The driving mechanism includes a pulley 14, a gear 15 and a rubber belt 16. The gear 15 and the pulley 14 are rotatably connected to the connecting bracket 5 through a bracket and a rotating shaft. The gear 15 is meshed with the rack 10. The pulley 14 and the soil crushing roller 6 are driven by the rubber belt 16. The two ends of the roller body of the soil crushing roller 6 are rotatably connected to the connecting bracket 5 through a rotating shaft and a bracket. The outer circumferential wall of the roller body is evenly provided with a plurality of auxiliary rods 601, and one side of the roller body is provided with a belt groove 602 that cooperates with the driving mechanism. By setting the gear 14 and the rack 10 to mesh internally to drive the pulley 14 to rotate, and then drive the soil crushing roller 6 to rotate through the rubber belt 16, it is ensured that the equipment can break up the agglomerated soil while shoveling the soil, and improve the linkage consistency of the equipment.

[0027] The output end of the motor 12 passes through the bottom of the equipment box 7 and is fixedly installed with the rotation center of the screw rod 11. An adjustment support frame 13 is fixedly installed in the carriage of the cart 1. Multiple adjustment ends of the adjustment support frame 13 are fixedly connected to the bottom of the equipment box 7. Multiple lifting rings 2 are fixedly installed around the top of the cart 1. A handrail is provided on one side of the cart 1. Multiple universal wheels are installed at the bottom of the cart 1. Each universal wheel is provided with a brake pad to ensure that the equipment is more stable when working. The adjustment support frame 13 is a support device with adjustable height, which is usually composed of a main pillar and one or more support arms. The support arms can be retracted or locked as needed to achieve support at different heights and angles. The arrangement of the cart 1 improves the flexibility of the equipment movement, and the arrangement of multiple lifting rings 2 facilitates the equipment to be dropped into the pipeline groove by a crane.

[0028] Working principle: When in use, according to the width of the excavated pipeline trench and the type of steel sheet piles, select the connecting bracket 5 and the blade 3 of appropriate length. After assembly, raise the two sets of shoveling mechanisms, and put the entire equipment into the pipeline trench through the crane and the lifting ring 2 on the equipment, push the cart 1 to the appropriate position in the middle of the pipeline trench, so that the two blades 3 are aligned with the tops of the steel sheet piles on both sides, start the motor 12 to drive the screw rod 11 to rotate, and the screw rod 11 drives the two connecting brackets 5 to slide along the slide 8 opened in the equipment box 7. At the same time, the two blades 3 shovel soil close to the surface of the steel sheet piles, and the gear 15 on one side of the connecting bracket 5 rotates as it meshes with the rack 10, and drives the pulley 14 to rotate, and the pulley 14 drives the soil crushing roller 6 to rotate through the rubber belt 16, and the soil shoveled by the blade 3 falls from the top of the soil crushing roller 6 along the mud guard 4 and is broken by it, and then falls to the bottom of the pipeline trench.
