Description

Technical Field

[0001] The utility model relates to the technical field of building foundation pits, in particular to a tool shovel for clearing soil between Larsen steel sheet piles. Background Art

[0002] Larsen steel sheet piles are used in most foundation pit support and foundation pit cofferdam projects. They are widely used in the construction industry because of their good water sealing effect, high rigidity, good toughness, modularization, and easy construction. However, when the foundation pit is excavated, the grooves of the Larsen steel sheet facing the pit will adhere to the earth, which is difficult to excavate and remove mechanically. If not removed in time, the earth will shrink and fall off, which poses a great safety hazard to the workers in the foundation pit. Therefore, they must be removed simultaneously when the foundation pit is excavated.

[0003] In the prior art, the bonded soil in the groove of the Larsen steel plate is generally removed manually. Workers use tools such as shovels to clean the soil between the piles, and they clean as they dig, which is time-consuming and labor-intensive. In addition, due to the inconsistent sizes of Larsen steel sheet piles, the width of the shovel cannot be matched with the groove of the Larsen steel plate, and the bonded soil in the groove cannot be removed at one time, resulting in low construction efficiency. Utility Model Content

[0035] The tool shovel for clearing soil between Larsen steel sheet piles comprises a threaded rod 1, a shovel plate 5, two rotating plates 4, a threaded sleeve 2, two connecting rods 3 and a driving mechanism;

[0036] The driving mechanism includes a driving motor 7, a gear 8, a rack 9, a moving rod 10 and a moving frame 6. The driving motor 7 is fixedly connected to the moving frame 6, the moving rod 10 is vertically slidably connected to the moving frame 6, the gear 8 is fixedly connected to the output shaft of the driving motor 7, the rack 9 is fixedly connected to the moving rod 10, the gear 8 and the rack 9 are meshed, the lower end of the moving rod 10 is rotatably connected to the upper end of the threaded rod 1, and the lower end of the threaded rod 1 is rotatably connected to the shovel plate 5. The driving motor 7 can drive the gear 8 to rotate, thereby driving the rack 9 to move, so that the moving rod 10 moves downward on the moving frame 6, so that the shovel plate 5 descends, and the shovel plate 5 is inserted between the groove of the Larsen steel sheet pile and the earthwork, so that the earthwork is separated from the groove of the Larsen steel sheet pile, and a roller is provided at the bottom of the moving frame 6, which facilitates the moving frame 6 to drive the device to move, thereby clearing the earthwork inside each groove of the Larsen steel sheet pile.

[0037] The top of the shovel plate 5 is fixedly connected with a reinforcement plate 503, the lower end of the threaded rod 1 is rotatably connected to the reinforcement plate 503, and the two sides of the back of the shovel plate 5 are fixedly connected with fixed shafts 502. Rotation holes 402 are opened on the two rotating plates 4, and each fixed shaft 502 passes through a rotation hole 402, so that the two rotating plates 4 can rotate around the fixed shaft 502, and the threaded sleeve 2 is threadedly connected to the outside of the threaded rod 1. The upper ends of the two connecting rods 3 are rotatably connected to the outside of the threaded sleeve 2, and the lower ends are rotatably connected to the two rotating plates 4 respectively. The two rotating plates 4 are symmetrically arranged, and the threaded rod 1 is rotated to make the threaded sleeve 2 move up and down, thereby driving the two rotating plates 4 to rotate and close or rotate and open respectively through the two connecting rods 3. The closing and opening of the two rotating plates 4 will change the width, so that the two rotating plates 4 can be adapted to fit with Larsen steel sheet pile grooves of different sizes. In the process of descending the shovel plate 5 and the two rotating plates 4, the earthwork inside the Larsen steel sheet pile groove is completely cleared at one time, thereby improving the efficiency of clearing the earthwork inside the Larsen steel sheet pile groove.

[0038] In order to facilitate the separation of soil and Larsen steel sheet piles when the shovel plate 5 is lowered, a first shovel blade 401 is provided on the side of the two rotating plates 4, and a second shovel blade 501 is provided at the bottom of the shovel plate 5. The first shovel blade 401 and the second shovel blade 501 are located on the same vertical plane, so that when the shovel plate 5 is lowered, the first shovel blade 401 and the second shovel blade 501 are attached to the surface of the Larsen steel sheet pile and descend to shovel up the adhered soil. The bottom of the shovel plate 5 is in a pointed cone shape, which is convenient for the shovel plate 6 to penetrate into the soil. A fixed plate 403 is provided on the front of the two rotating plates 4. The front of the shovel plate 5 and the front of the fixed plate 403 have ridge-like protrusions, which facilitate peeling the soil from the groove of the Larsen steel sheet pile.

[0039] The working principle of the tool shovel for clearing soil between Larsen steel sheet piles is as follows: firstly, the two rotating plates 4 are adjusted according to the width of the Larsen steel sheet pile groove, that is, the threaded rod 1 is rotated to move the threaded sleeve 2 up and down, thereby driving the two rotating plates 4 to rotate and close or rotate and open through the two connecting rods 3 respectively. The closing and opening of the two rotating plates 4 will change the width, so that the two rotating plates 4 can be adapted to fit the width of the Larsen steel sheet pile groove;

[0040] Then, the gear 8 is driven to rotate by the driving motor 7, thereby driving the rack 9 to move, so that the moving rod 10 moves downward on the moving frame 6, so that the shovel plate 5 descends, and the pointed cone of the shovel plate 5 is inserted between the groove of the Larsen steel sheet pile and the earth. Then, the first shovel blade 401 and the second shovel blade 501 descend in contact with the surface of the Larsen steel sheet pile, and the adhered earth is shoveled up, and the ridge-like protrusions on the front of the shovel plate 5 and the front of the fixed plate 403 peel off the earth from the groove of the Larsen steel sheet pile, so that the earth is separated from the groove of the Larsen steel sheet pile. Since the width of the two rotating plates 4 is consistent with the width of the Larsen steel sheet pile groove, the earth inside the Larsen steel sheet pile groove can be completely cleared at one time, thereby improving the efficiency of clearing the earth inside the Larsen steel sheet pile groove;

[0041] Finally, the device is driven to move by the rollers at the bottom of the mobile frame 6, so that the device moves above each groove of the Larsen steel sheet pile, thereby clearing the earth inside each groove of the Larsen steel sheet pile.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
