Description

Technical Field

[0001] The present invention relates to the technical field of pile hole slag cleaning, and particularly relates to a device for cleaning residues at the bottom of a pile foundation hole. Background Art

[0002] Drilling pile holes is a necessary step in arranging various bored cast-in-place piles on the foundation to improve the bearing capacity of the foundation. During the construction process of pile holes, due to the low precision of large machinery, it is impossible to clean the residues at the bottom of the pile holes, resulting in low construction quality of pile holes and difficulty in meeting the design bearing requirements. Therefore, it is necessary to go deep into the pile holes to clean the residues at the bottom. In the past, the slag cleaning work at the bottom of pile holes was mainly carried out by manual operation in the well, which was inefficient and had certain risks.

[0003] Lin Jian, Chen Shengquan, etc. invented a suction type device for cleaning residues at the bottom of a pile foundation hole (Patent No.: CN201120531838.5). This invention uses the movement of the piston in the oil cylinder to generate suction, sucking the thin soil and slag at the bottom of the pile foundation hole into the cylinder body and transporting it to the ground. This method can clean pile foundation holes with relatively small depths, but when the depth of the pile foundation hole is large, the suction will be insufficient. In addition, the suction type slag cleaning cannot suck and clean larger slag. Summary of the Invention

[0042] The L-shaped support member 21 in the multi-directional telescopic mechanism 2 is installed with its inner side facing the opening side of the soil collecting box 43. The bucket 26 is installed on the inner side of the L-shaped support member 21, and the main body of the bucket 26 is also of an L-shaped structure, and there are side baffles on the left and right sides of the main body of the bucket, so as to protect the rotary tiller 3, and it can make the rotary tiller 3 better throw the muck into the soil collecting box 43 when working. The main actions of the multi-directional telescopic mechanism 2 are realized by the horizontal expansion and contraction of the L-shaped support member 21 and the longitudinal sliding of the bucket 26.

[0043] The main function of the rotary tiller 3 is to loosen or lift the muck at the bottom of the hole, and it can throw part of the muck into the soil collecting box 43. At the same time, when the bucket 26 retracts horizontally, it can also rake the muck into the soil collecting box 43.

[0044] According to some embodiments of the present application, the traveling chassis 1 further includes a traveling wheel loading platform 13 and traveling wheels 15. The traveling wheel loading platforms 13 are respectively fixedly arranged at the bottoms on both sides of the portal opening of the bearing platform 11, and two traveling wheels 15 are installed below each traveling wheel loading platform 13. The above-mentioned traveling wheel loading platforms 13 can be fixedly welded to the bottoms on the left and right sides of the bearing platform 11 to serve as the installation basis for the traveling wheels 15.

[0045] According to some embodiments of the present application, the traveling chassis 1 further includes a chassis motor distribution box 14, inside which a motor drive assembly is installed. A chain drive assembly 16 for transmitting power is installed between the chassis motor distribution box 14 and the traveling wheels 15.

[0052] According to some embodiments of the present application, cameras 18 and lighting lamps are provided at both ends of the carrying platform 11 along the running direction of the traveling chassis 1. The cameras 18 are provided to assist the operator in obtaining information before and after the device, and the lighting lamps are provided to provide necessary lighting conditions for the cameras 18.

[0053] Specifically, there are two cameras 18, which are respectively installed at the front and rear ends of the carrying platform 11; there are four lighting lamps, which are respectively installed at the front and rear ends of the traveling chassis 1, with two lighting lamps at each end.

[0054] According to some embodiments of the present application, a control component distribution box 12 is provided on the top of the carrying platform 11. The control component distribution box 12 is used to receive external signals to control the movement trajectory of the traveling chassis 1. The control component distribution box 12 can be installed on the top of the carrying platform 11 by bolts.

[0055] According to some embodiments of the present application, one end of the soil collection box 43 away from the rotary tiller 3 is rotatably connected to the carrying platform 11 through a tipping mechanism 41, and one end close to the rotary tiller 3 is movably connected to the carrying platform 11 through a pin mechanism. After the above-mentioned pin connection is released, the soil collection box 43 can rotate relative to the carrying platform 11, so that the opening side of the soil collection box 43 rotates downward, thereby dumping the muck collected in the soil collection box 43.

[0056] According to some embodiments of the present application, the tipping mechanism 41 includes a support member 411 and a soil collecting box shaft 42. The support member 411 is disposed on the carrying platform 11. The soil collecting box shaft 42 is connected to the soil collecting box 43, and both ends of the soil collecting box shaft 42 are rotatably connected to the support member 411 through bearings 412. The pin mechanism includes a fixed pin plate 17, a fixed pin shaft 44, and a check pin 45. The fixed pin plate 17 is disposed on the traveling chassis 1. The fixed pin shaft 44 is movably inserted through the fixed pin plate 17 and the soil collecting box 43. The check pin 45 is disposed on the fixed pin shaft 44 and is located inside the soil collecting box 43.

[0057] Specifically, the fixed pin plate 17 is fixed to the traveling wheel loading platform 13 by welding to fix the soil collecting box 43. The fixed pin shaft 44 is movably inserted into preset pin holes on the fixed pin plate 17 and the soil collecting box 43. When it is necessary to clean the soil in the soil collecting box 43, after removing the check pin 45 and pulling out the fixed pin shaft 44, the soil collecting box 43 can rotate around the soil collecting box shaft 42, so as to realize the dumping of the soil inside the soil collecting box 43.

[0058] The specific working mode of the device in the present application is as follows:

[0059] The device is sent into the pile foundation hole for operation by an external hoisting device pulling four lifting rings at the top of the device. When reaching the predetermined operation position, the towing rope is relaxed so that the device can move in the pile hole and perform slag cleaning operation.

[0060] After the device reaches the predetermined position, the operator operates the remote controller to control the device to start. After receiving the start command, the device first turns on the front and rear lighting lamps and the camera 18. The operator understands the distribution of the soil at the bottom of the pile hole through the camera 18 and prepares for operation. The operator can remotely control the same-direction rotation of the two traveling wheels 15 on one side of the device through the remote controller. When moving forward, the traveling wheels 15 on both the left and right sides rotate forward. When moving backward, it is the opposite. When turning left, the traveling wheel 15 on the left side rotates in the reverse direction, and the traveling wheel 15 on the right side rotates forward to realize a left turn. When turning right, it is the opposite. That is, the device turns by the differential speed of the traveling wheels on the left and right sides.

[0061] When the operator operates the device to reach the predetermined working position and issues a slag cleaning instruction through the remote control, the device performs a slag cleaning operation according to a predetermined program. The program flow is as follows: After receiving the operation instruction, the horizontal electric push rod 23 first extends, pushing the multi-directional telescopic mechanism 2 to move linearly outwards. When it reaches the predetermined position, the magnetic switch on the horizontal electric push rod 23 transmits a signal back to the control component distribution box 12, stopping the extension of the horizontal electric push rod 23, and starting the extension of the vertical electric push rod 27 and the operation of the DC motor 311 of the rotary tiller 3. The vertical electric push rod 27 pushes the bucket 26 to drive the rotary tiller 3 to simultaneously probe down into the muck. When the probing action reaches the predetermined position, the magnetic switch on the vertical electric push rod 27 also transmits a signal back to the control component distribution box 12, and the vertical electric push rod 27 stops the extension movement. The rotary tiller 3 still rotates. The horizontal electric push rod 23 and the vertical electric push rod 27 start to retract, driving the bucket 26 and the rotary tiller 3 to retract, and raking the muck back into the soil collection box 43. When both the horizontal electric push rod 23 and the vertical electric push rod 27 retract to the predetermined position, the magnetic switch transmits a signal back to the control component distribution box 12, and the horizontal electric push rod 23, the vertical electric push rod 27, and the rotary tiller 3 all stop moving, waiting for the next operation signal.

[0062] After several operations, a certain amount of muck has been collected in the soil collection box 43. Then, the device is lifted out of the pile foundation hole by a hoisting device. By pulling out the fixed pin shaft 44 of the soil collection box 43 from between the fixed pin plate 17 on the soil collection box 43 and the traveling chassis 1, the soil collection box 43 can rotate around the soil collection box shaft 42, so as to dump the muck to the predetermined position above the well. After dumping, the soil collection box 43 is reset and fixed with the fixed pin shaft 44.

[0063] The specific embodiments described above further elaborate on the purpose, technical solutions, and beneficial effects of the present invention. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
