Description

Technical Field

[0001] This utility model relates to the field of foundation pit construction technology, and in particular to a foundation pit construction soil removal device. Background Technology

[0002] Currently, in recent years, with the gradual improvement of environmental and safety awareness, traditional methods of foundation pit excavation, such as ramp excavation and step relay excavation, have been widely criticized. However, there is still no mature equipment or method specifically designed for deep foundation pit excavation to replace them.

[0003] A search of Chinese patent CN211998554U reveals a device for removing excavated soil during foundation pit construction. The device includes a foundation pit, a first base plate placed on the upper surface of the foundation pit, a transport box placed on the right side of the first base plate, a first fixing plate detachably connected to the upper surface of the first base plate, a cylinder fixedly connected to the upper surface of the first fixing plate, a fixing rod fixedly connected to the upper surface of the cylinder, and a second wall plate fixedly connected to the upper surface of the fixing rod.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] Existing excavation equipment for foundation pit construction typically uses steel strands to lift the soil upwards. However, due to the uneven amount of soil inside the soil container, the rising container is prone to shaking, which reduces the practicality of the equipment. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a soil removal device for foundation pit construction. The starting motor drives the rotating shaft to rotate, which in turn drives the worm and worm wheel to rotate. When the friction angle between the worm wheel and the worm is less than the helix angle of the worm, self-locking can be achieved. This drives the gear on the rotating column to rotate, which in turn drives the fixed shell on the rack to move. The stability of the fixed shell during movement can be improved by the setting of slide rails and sliding blocks. Then, the soil loading box is rotated by the hydraulic telescopic rod and rotating rod on the bottom plate, so that it is inserted into the foundation pit.

[0007] The technical solution to achieve the purpose of this utility model is: a soil removal device for foundation pit construction, including a base plate, a soil loading box on one side of the base plate, a plurality of support plates fixedly connected to the bottom of the soil loading box, and a fixed shell fixedly connected to the top of each of the plurality of support plates, and also including;

[0008] An adjustment mechanism is located on the base plate;

[0009] The adjustment mechanism includes a power unit and an adjustment unit. The power unit includes an outer shell that is fitted onto multiple fixed shells. A motor is fixedly connected to one side of each of the multiple outer shells. The output ends of the multiple motors are fixedly connected to rotating shafts via couplings. A worm is fixedly connected to one end of each of the multiple rotating shafts. Rotating columns are rotatably connected to the inner walls on both sides of the multiple outer shells. Worm wheels are keyed to each of the multiple rotating columns. The worm and the worm wheel mesh with each other.

[0010] In some embodiments, the adjustment unit includes slide rails formed on the inner wall of one side of multiple housings, sliding blocks slidably connected to each slide rail, one side of each sliding block fixedly connected to a fixed housing, racks fixedly connected to the top of each fixed housing, two gears keyed to each of multiple rotating columns, a worm gear located between the two gears, the gears meshing with the racks, and a square block fixedly connected to the top of each of the multiple housings.

[0011] In some embodiments, a stop block is fixedly connected to one side of the inner wall of each of the plurality of housings, and a movable block is fixedly connected to one side of each of the plurality of racks.

[0012] In some embodiments, a hydraulic telescopic rod is mounted on the top of the base plate, an installation plate is fixedly connected to the output end of the hydraulic telescopic rod, a rotating rod is mounted on the top of the installation plate, and an elongated plate is fixedly connected to the top end of the rotating rod.

[0013] In some embodiments, two U-shaped frames are fixedly connected to the bottom of the elongated plate, and square blocks are fixedly connected to the bottom of each U-shaped frame. Square blocks are fixed together with bolts.

[0014] In some embodiments, an operation panel is mounted on the top of the base plate.

[0015] Compared with existing technologies, the significant advantages of this invention are:

[0016] This utility model uses bolts to fix square blocks one and two, then starts a motor to drive the rotating shaft to rotate, which in turn drives the worm and worm wheel to rotate. When the friction angle between the worm wheel and the worm is less than the helix angle of the worm, self-locking can be achieved, driving the gear on the rotating column to rotate, which in turn drives the fixed shell on the rack to move. The setting of slide rails and sliding blocks can improve the stability of the fixed shell during movement. Then, the hydraulic telescopic rod and rotating rod on the base plate rotate the soil-filling box, so that it is inserted into the foundation pit. This makes it easy to move the soil-filling box up and down to a certain extent, while ensuring the stability of the soil-filling box during movement and preventing tilting, thereby improving the practicality of the device.

[0017] This invention addresses the problem that existing excavation devices for foundation pit construction typically use steel strands to lift the soil upwards. However, due to the uneven amount of soil inside the soil container, the rising soil container is prone to shaking, thus reducing the practicality of the device. Attached Figure Description

Worm wheels 10 are keyed to each of the multiple rotating columns 9, and the worms 8 and worm wheels 10 mesh with each other. The power unit facilitates the rotation of the rotating columns 9 and allows for locking of the rotated position of the rotating columns 9.

[0027] like Figure 2 As shown, in one embodiment, the adjustment unit includes slide rails 12 formed on the inner wall of one side of multiple outer shells 5, with sliding blocks 13 slidably connected to each slide rail 12. One side of each sliding block 13 is fixedly connected to a fixed shell 4. A rack 14 is fixedly connected to the top of each fixed shell 4.
