Technical Field
[0001] The invention belongs to the technical field of construction equipment, and in particular relates to an intelligent automatic digging device for a deep foundation pit enlargement head. Background Art
[0002] Deep foundation pit enlarged head is an anchor cable construction method specially designed to solve the problem of insufficient anchoring force of anchor cables in deep foundation pit support, especially in soft soil areas in the south. This method can significantly reduce the length of the anchor section and reduce engineering interference in adjacent areas through the use of enlarged head anchor cables, while saving engineering costs. The main difference between enlarged head anchor cables and ordinary tension anchor cables is that the force point of the enlarged head anchor cable is located at the front end of the anchor body, and the force is transmitted to the anchor body through the pressure plate located at the top of the anchor section, so that the anchor body is stressed as a whole, thereby giving full play to the role of the anchor body. This design not only improves the safety of the project, but also reduces the creep of the anchor cable and improves the performance of the project.
[0003] If you want to use the enlarged head anchor cable construction method, you need to expand the space at the bottom of the anchor hole when digging the anchor hole for installing the anchor cable. Traditional drilling equipment is difficult to complete this operation. In addition, when expanding the space at the bottom of the anchor hole, it is also very difficult to discharge the excavated waste, which greatly affects the construction efficiency. Summary of the invention

When the excavation depth of the anchor hole is reached, the adjustment tube slides vertically on the outer probe tube to drive the expansion mechanism to extend, and the outer probe tube continues to rotate. After the expansion mechanism extends, it rotates with the outer probe tube, so that the bottom of the anchor hole is gradually expanded, and the waste slag generated during the excavation of the anchor hole can be discharged through the inner probe tube, so that the anchor hole with the enlarged bottom can be easily excavated, thereby improving the construction efficiency of the enlarged head anchor cable construction method.
[0007] Furthermore, a driven gear is fixedly connected to the top of the outer probe tube, and a driving gear is fixedly connected to the bottom of the driving motor shaft, and the driving gear is meshed with the driven gear.
[0008] Through the above technical solution, since a driven gear is fixedly connected to the top of the outer probe tube and a driving gear is fixedly connected to the bottom of the driving motor shaft, the driving gear is meshed with the driven gear, and the outer probe tube is rotatably connected to the inner probe tube, so that the rotation of the driving motor can drive the outer probe tube to rotate.

[0011] Furthermore, the adjustment assembly includes an upper adjustment disk and a lower adjustment disk, the outer probe penetrates the upper adjustment disk and the lower adjustment disk, and the upper adjustment disk and the lower adjustment disk are fixedly connected by an arc rod.
[0012] Through the above technical solution, since the outer probe tube passes through the upper adjustment plate and the lower adjustment plate, the upper adjustment plate and the lower adjustment plate are fixedly connected by the arc rod, so that the upper adjustment plate slides on the outer probe tube and can drive the lower adjustment plate to slide on the outer probe tube at the same time.
[0013] Furthermore, there are multiple expansion components, and the expansion components are equidistantly arranged on the adjustment component. The expansion component includes an arc scraper, a main rod and a support rod. The arc scraper is hinged at the top of the main rod. A base plate is fixedly connected above the drill bit on the outer probe tube. The bottom of the main rod is hinged to the base plate, the top of the support rod is hinged to the main rod, and the bottom of the support rod is hinged to the lower adjustment plate.

[0015] Furthermore, the main rod is provided with a through slot, and the elastic enclosure is fixedly connected to the plurality of main rods via the through slot, and the elastic enclosure can be extended or contracted along with the main rods.
[0016] Through the above technical scheme, since the elastic enclosure can extend or contract with the main rod, after the main rod is extended, the arc scraper extends with the main rod. At this time, the outer probe rotates and the arc scraper rotates accordingly. The arc scraper can excavate the inner wall of the bottom of the anchor hole. The main rod can also excavate the inner wall of the bottom of the anchor hole at the same time, thereby expanding the space at the bottom of the anchor hole, and the waste slag generated during the excavation process can be collected by the elastic enclosure.
[0017] Furthermore, a telescopic assembly is fixedly connected to the top of the adjusting cylinder, and the top of the adjusting cylinder can be clamped with the upper adjusting disk.
[0018] With the above technical solution, since the top of the adjusting tube can be clamped with the upper adjusting disk, when the adjusting tube slides on the outer probe tube, it can drive the upper adjusting disk to slide on the outer probe tube, that is, drive the adjusting assembly to slide on the outer probe tube.
[0019] Furthermore, a connecting block is symmetrically fixedly connected to the top of the adjusting cylinder, elastic balls are arranged on both sides of the connecting block, and a rectangular groove and a circular groove are correspondingly arranged on the bottom of the upper adjusting plate, the circular grooves are symmetrically arranged on both sides of the rectangular groove, the connecting block can be clamped in the rectangular groove, and the elastic ball can be clamped in the circular groove.

At this time, the vertical sliding of the adjusting cylinder on the outer probe tube can drive the upper adjusting disk to slide vertically on the outer probe tube, that is, drive the lower adjusting disk to slide vertically on the outer probe tube; When the adjusting cylinder descends and drives the lower adjusting disk to descend to the lowest position, the adjusting cylinder continues to descend, the top of the adjusting cylinder can be released from the clamping connection with the upper adjusting disk, and the adjusting cylinder can continue to descend.
[0021] Furthermore, the telescopic assembly includes a rotating disk and an electric telescopic rod, the top of the electric telescopic rod is fixed to the rotating disk, the bottom of the electric telescopic rod is fixedly connected to the adjustment cylinder, and the rotating disk is rotatably connected to the bottom of the base plate.
[0022] Through the above technical solution, since the top of the electric telescopic rod is fixed to the rotating disk and the bottom of the electric telescopic rod is fixedly connected to the adjusting tube, the extension and retraction of the electric telescopic rod can drive the adjusting tube to slide vertically on the outer probe tube, and the connecting rod connecting the electric telescopic rod and the adjusting tube passes through the driven gear, and the rotating disk is rotatably connected to the bottom of the base plate, so that when the driving motor drives the outer probe tube to rotate, the adjusting tube can rotate accordingly.

[0024] According to the above technical solution, since a first grid is provided at the lower part of the outer probe tube, a second grid is provided on the inner probe tube, and the second grid and the first grid are provided at the same height, the waste residue generated by excavation after the expansion mechanism is deployed can enter the inner probe tube through the first grid and the second grid; During excavation, the first grid on the outer probe rotates with the outer probe, so that when the waste residue passes through the first grid and the second grid, the mutual rotation of the first grid and the second grid grinds and crushes the waste residue, thereby reducing the volume and weight of the waste residue and facilitating discharge; Since the bottom of the drill bit is hollowed out, the filter screen is fixedly connected to the bottom of the inner probe tube, so that the waste residue produced by the drill bit can enter the inner probe tube through the filter screen; Since a joint is fixedly connected to the top of the inner probe tube, the inner probe tube can be connected to a dust suction pipe to suck out the waste residue entering the inner probe tube, thereby facilitating the discharge of the waste residue generated by excavation.
[0025] The beneficial effects of the present invention are as follows: (1) In the present invention, the adjusting tube drives the lower adjusting plate to slide upward on the outer probe tube to drive the support rod to extend, and the extension of the support rod can drive the main rod to extend, and the arc scraper can extend with the main rod, and the outer probe tube continues to rotate, and the arc scraper rotates accordingly. The arc scraper can dig the inner wall of the bottom of the anchor hole, and the main rod can also dig the inner wall of the bottom of the anchor hole at the same time, thereby expanding the space at the bottom of the anchor hole, facilitating the construction of the enlarged head anchor cable construction method, and simplifying the construction difficulty; (2) In the present invention, the adjusting tube drives the lower adjusting plate to slide downward on the outer probe tube, which can drive the support rod to contract, and the contraction of the support rod can drive the main rod to contract, and the arc scraper can contract with the main rod. At this time, the elastic enclosure also contracts, so that the waste slag generated by excavation gathers toward the first grid. The first grid on the outer probe tube rotates with the outer probe tube, so that when the waste slag passes through the first grid and the second grid, the mutual rotation of the first grid and the second grid grinds the waste slag, thereby reducing the volume and weight of the waste slag, facilitating discharge, and improving work efficiency; (3) After the expansion of the bottom space of the anchor hole in the present invention is completed, the adjusting cylinder descends and drives the lower adjusting plate to descend to the lowest point, and then the adjusting cylinder continues to descend, and the top of the adjusting cylinder can be released from the upper adjusting plate. At this time, the expansion mechanism is in a contracted state, and the adjusting cylinder continues to descend until the adjusting cylinder descends to wrap the expansion mechanism, thereby providing comprehensive protection for the expansion mechanism, making it convenient to pull the entire device out of the anchor hole after the excavation is completed, which not only protects the device, but also simplifies the operation and improves the construction efficiency.

Then the adjusting cylinder 4 continues to descend, and the top of the adjusting cylinder 4 can be released from the upper adjusting disk 311. At this time, the expansion mechanism 3 is in a contracted state, and the adjusting cylinder 4 continues to descend until the adjusting cylinder 4 descends to wrap the expansion mechanism 3, thereby fully protecting the expansion mechanism 3, making it convenient to pull the entire device out of the anchor hole after the excavation is completed, thereby improving work efficiency.
