Description
Technical Field
[0001] This utility model belongs to the field of foundation pit construction, and in particular relates to a handwheel shovel for cleaning soil between Larssen steel sheet piles. Background Technology
[0002] When using Larssen sheet piles for trench support, the grooves inherent in the sheets make it difficult to effectively clear the soil between the piles during excavation. Some soil remains trapped within these grooves, easily detaching as the soil dries and shrinks, posing a significant safety hazard to trench construction. Current solutions primarily involve manually removing soil from the edge or inside the pit using steel pipes and shovels. However, manual soil removal carries the risk of falls from heights and is inefficient. Summary of the Invention
[0003] The problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a hand-wheeled shovel for cleaning the soil between Larssen sheet piles.
[0004] This invention is achieved through the following technical solution: A handwheeled shovel for cleaning soil between Larssen sheet piles includes a vertical fixed rod with fixed plates welded to its left and right sides. A vertical rack with the same width as the fixed rod is attached to the front side of the fixed rod. The rack meshes with a gear fixed to a rotating shaft, which is mounted on the fixed plate via a bearing. The rotating shaft passes through one of the fixed plates and has a crank handle connected to its outer end. A connecting rod is fixed to the outer side of the fixed plate on the side away from the crank handle. The lower end of the connecting rod is fixed to the upper end of a U-shaped clamp. A bolt is threaded onto the front side of the U-shaped clamp, and a clamping plate is fixed to the end of the bolt that extends into the U-shaped clamp. The lower part of the rear side of the rack is beveled, and a U-shaped shovel plate is fixed to the beveled surface. The width of the U-shaped shovel plate is smaller than the inner width of the groove of the Larssen sheet pile, and the bottom end of the U-shaped shovel plate can abut against the inner wall of the groove of the Larssen sheet pile.
[0005] Preferably, the rack comprises several racks, each with a threaded hole on its upper and lower end faces, and adjacent racks are joined together by a screw connected to the threaded hole.
[0006] Preferably, a handle is vertically fixed outward at the upper part of the connecting rod.
[0007] Preferably, both the upper and lower parts of the fixing rod are fixed with limit plates.
[0008] Preferably, the bolt end is provided with a flat knob.
[0009] Using the device of this invention, workers can manually clean the soil between piles above the foundation pit, avoiding the safety risks of manual soil cleaning and greatly improving the soil cleaning efficiency. The device of this invention can extend the rack according to the groove depth of the Larssen sheet pile, thereby adjusting the length of the rack, which is suitable for cleaning the soil between piles at different depths. In addition, the U-shaped clamp of the device can be clamped on Larssen sheet piles of different thicknesses, making it highly versatile. Attached Figure Description

Detailed Implementation
[0012] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.
[0013] This embodiment includes a vertical fixing rod 1, which is rectangular. Fixing plates 2 are welded to the left and right sides of the fixing rod 1, respectively. The two fixing plates 2 are parallel and extend forward. A vertical rack 3 is provided against the front side of the fixing rod 1. The rack 3 can move up and down, and its width is equal to the width of the fixing rod 1. The rack 3 passes between the two fixing plates 2. To further limit the rack 3, preferably, limiting plates 15 are symmetrically fixed to the left and right sides of the upper and lower parts of the fixing rod 1.
[0014] The aforementioned rack 3 meshes with a gear 4, which is located between two fixed plates 2. The gear 4 is fixed on a rotating shaft 5, which is perpendicular to the fixed plates 2. The rotating shaft 5 is mounted on the fixed plates 2 on both sides via bearings and can rotate within the bearings. The rotation of the rotating shaft 5 drives the gear 4 to rotate, which in turn drives the rack 3 to move up and down. The rotating shaft 5 passes outward through one of the fixed plates 2, and a crank 6 is connected to the outer end of the rotating shaft 5. The rotating shaft 5 is manually rotated by the crank 6, thereby rotating the gear 4. Since the depth of the Larssen sheet piles that need to be cleared varies, the total length of the rack 3 can be adjusted by joining several racks 3 together. Preferably, the rack 3 consists of several racks, each with threaded holes on its upper and lower end faces. A screw 13 is threaded into the threaded holes, and adjacent racks 3 are joined together by the screw 13 in the threaded holes. This can be used to clear soil between piles at different depths. Of course, a single, longer rack 3 can also be used.
[0015] A vertical connecting rod 7 is fixed to the outer surface of the fixing plate 2 on the side away from the crank handle 6. The lower end of the connecting rod 7 is fixed to the upper end of a U-shaped clamp 8. A bolt 9 is threadedly connected to the front side of the vertical U-shaped clamp 8. A clamping plate 10 is fixed to the end of the bolt 9 that extends into the U-shaped clamp 8. The device can be fixed to the steel plate at the groove of the Larssen sheet pile through the U-shaped clamp 8 and the clamping plate 10. The U-shaped clamp 8 designed in this embodiment can also be adjusted according to the thickness of the Larssen sheet pile steel plate. The U-shaped clamp 8 is clamped downwards onto the steel plate at the end of the groove of the Larssen sheet pile, and then the bolt 9 is tightened until the clamping plate 10 is tightly pressed against the outer wall of the groove steel plate, thus realizing the fixation between the U-shaped clamp 8 and the Larssen sheet pile, thereby fixing the entire device to the end of the Larssen sheet pile. To facilitate the tightening of the bolt 9, it is preferable that the end of the bolt 9 is provided with a flat knob 16. To facilitate the movement of the entire device, it is preferable that a lifting handle 14 is vertically fixed outwards on the upper part of the connecting rod 7.
[0016] The lower rear side of the lowest rack 3 is a beveled surface 11, which is inclined toward the outside of the pit. A U-shaped shovel 12 is fixed on the beveled surface 11. The width of the U-shaped shovel 12 is smaller than the inner width of the groove of the Larssen sheet pile. The U-shaped shovel 12 is placed in the groove, and the U-shaped shovel 12 and the beveled surface 11 are inclined at the same angle. The U-shaped shovel 12 is inclined toward the inner wall of the groove of the Larssen sheet pile. When the U-shaped clamp 8 is clamped on the Larssen sheet pile, the bottom end of the U-shaped shovel 12 can abut against the inner wall of the groove of the Larssen sheet pile. The U-shaped shovel 12 moves up and down to remove and clean the soil between the piles on the inner wall of the groove.
[0017] In use, hold the handle 14 to clamp the U-shaped clamp 8 onto the steel plate at the end of the groove of the Larssen sheet pile, and tighten the bolt 9 to make the U-shaped clamp 8 firmly clamp onto the steel plate of the groove. At this time, the bottom end of the U-shaped shovel also abuts against the inner wall of the groove. The worker turns the crank handle 6 to rotate the shaft 5. The shaft 5 drives the gear 4 to rotate. The rotation of the gear 4 causes the rack 3 to move downward. The downward movement of the rack 3 drives the U-shaped shovel plate 12 to move downward along the inner wall of the groove, thereby removing and cleaning the soil between the piles on the inner wall of the groove. When the rack 3 is not long enough, it can be extended upward by the screw 13. The U-shaped shovel plate 12 can be moved up and down repeatedly to clean the soil. After cleaning this position, move the U-shaped clamp 8 to the next position to clean the soil.
[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; those skilled in the art should understand that modifications can still be made to the technical solutions described in the above embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
