Description

Technical Field

[0001] This application belongs to the technical field of precast pipe pile hole cleaning, and in particular relates to a hand-cranked positioning automatic hole cleaning device for precast pipe piles and its construction method. Background Art

[0002] Currently, during the construction of precast pipe piles, first the piling construction is carried out, and then the earthwork excavation is carried out. It often takes a long time from the completion of the pile foundation construction to the earthwork excavation. During this period, dust and rainy season silt will enter the precast pipe piles, and during the earthwork excavation, a certain amount of earth will fall into the precast pipe piles. If the soil in the pipe piles is not cleaned in the above two situations, it will lead to insufficient length under the steel cage in the subsequent construction, reduced anchorage of the concrete, insufficient concrete filling, reduced concrete pouring quality, and ultimately affect the construction quality. Currently, a Luoyang shovel is used for hole cleaning of precast pipe piles, which is time-consuming and laborious and greatly reduces the project progress.

[0003] For conventional precast pipe pile hole cleaning technology, generally a Luoyang shovel is used to clean out the soil. The traditional precast pipe pile hole cleaning method has the following deficiencies: it can only clean pipe piles with relatively shallow depths; it is time-consuming and laborious to clean out the soil and the cleaning is not thorough; the manual hole cleaning by construction workers has low efficiency and increases labor costs. Summary of the Invention

[0004] This application provides a hand-cranked positioning automatic hole cleaning device for precast pipe piles and its construction method to solve the technical problems of the existing relatively shallow cleaning depth and difficult mud scooping.

[0005] To solve at least one of the above technical problems, the technical solution adopted in this application is:

[0006] A hand-cranked positioning automatic hole cleaning device for precast pipe piles, comprising:

[0007] A cleaning component, which is provided with a spiral blade and a motor for driving the spiral blade to work;

[0008] A support component, which is provided with a support frame, a sliding support for fixing the motor and making the spiral blade vertically downward, a gear set and a chain for driving the sliding support to move up and down along the height direction of the support frame;

[0009] A roller set for driving the whole support frame to move is further provided below the support frame;

[0010] Pushing the support frame can drive the cleaning component to move to the position of the pipe pile to be cleaned through the roller set; after the support frame is horizontally placed, the gear set drives the cleaning component to adjust the height position of the spiral blade through the chain; after the position is adjusted, the motor drives the spiral blade to start cleaning.

[0011] Further, the spiral blade is fixed on a shaft rod connected to the output end of the motor; a switch is also provided on the motor.

[0012] Further, the support frame includes an open frame composed of two long rods and two L-shaped short rods. The two short rods are welded in an inverted manner to the lower segments of the two long rods and form four legs of the same height.

[0013] Further, a conical support foot is fixedly provided below each of the four legs. The large end diameter surface of the conical support foot is welded to a disc connected to the leg.

[0014] Further, the roller group is configured at the bottom on one side of the long rod and is located between the two legs; on the side close to the spiral blade, a group of inclined rods is also provided to connect the long rod and the short rod.

[0015] Further, the sliding support is constructed in a tray-like structure. The motor is fixed above the sliding support, and its tail is connected to a chain provided on the long rod through a connecting frame; a fender is also provided at the end of the long rod close to the roller group.

[0016] Further, the gear group is fixed on the side surface of the long rod away from the spiral blade and is connected to the sliding support through a chain; and the gear group is arranged on the same side as the roller group.

[0017] Further, two guide rod frames cooperating with the sliding support are also provided on the side of the long rod close to the spiral blade, and scales are provided on the upper segments of the guide rod frames.

[0018] Further, a handrail is also provided on the upper segment of the long rod on the side close to the gear group, and a handle for driving the movement of the gear group is provided below the handrail. Driving the handle drives the chain on the gear group to rotate, so that the spiral blade can be driven to move up and down through the sliding support.

[0019] A construction method for precast pipe pile hand-cranked positioning and automatic hole cleaning uses the hole cleaning device as described above, and the steps include:

[0020] S1. Push the support frame, and the roller group can drive the cleaning component to move to the position of the pipe pile to be cleaned, and make the spiral blade vertically downward through the support frame;

[0036] The present application will be described in detail below with reference to the drawings and specific embodiments.

[0037] This embodiment provides a precast pipe pile hand-cranked positioning automatic hole cleaning device, as Figures 1-4 shown, which includes a cleaning component for cleaning sludge and a support component for adjusting the position of the cleaning component. Among them, the cleaning component includes a spiral blade 10 and a motor 20 for driving the spiral blade 10 to work, and a switch 21 is provided on the motor 20. The support component includes a support frame 30, a sliding support 40 for fixing the spiral blade 10 vertically downward, a gear set 50 for driving the sliding support 40 to move up and down along the height direction of the support frame 10, and a chain; and a roller set 60 capable of driving the entire support frame 30 to move is also provided below the support frame 30. By pushing the support frame 30 through the roller set 60, the cleaning component can be driven to move to the position of the pipe pile to be cleaned; after the support frame 30 is horizontally placed, the spiral blade 10 is controlled to be vertically downward, and the gear set 50 is driven to drive the cleaning component to adjust the height position of the spiral blade 10 through the chain, so that the spiral blade 10 is directly above the hole to be cleaned; after the position is adjusted, the motor 20 drives the spiral blade 10 to start cleaning the silt in the hole.

[0038] As Figures 1-2 shown, the spiral blade 10 is fixed on a shaft rod connected to the output end of the motor 20 and is arranged around the length direction of the shaft rod. And a switch 21 is also provided on the outer side surface of the motor 20. By starting the motor 20 through the switch 21, the motor 20 can drive the spiral blade 10 to rotate, so that it can enter the hole to be cleaned to clean the silt. The cut silt moves up along the rotating spiral blade 10 and leaves the hole, thus completing the silt cleaning work of the pipe pile.

[0039] The support frame 30 includes an open frame composed of two long rods 31 and two L-shaped short rods 32. Among them, the two short rods 32 are welded in an inverted manner at the lower section of the two long rods 31 and form four legs of the same height. A conical support foot 38 is respectively fixed below the four legs, and the large end diameter surface of the conical support foot 38 is welded to a disc connected to the leg. The setting of the conical support foot 38 facilitates placing the support frame 30 on the soil base surface. The pointed conical support foot 38 is easier to insert into the soil base surface to improve the stability of the support frame 30. Moreover, the conical support foot 38 is easier to support on a road or a cement road and can also be inserted and fixed on the road surface; the setting of the disc can further improve the fixing strength between the support foot 38 and the leg.

[0040] The roller set 60 is configured at the bottom on one side of the long rod 31 and is located between the two legs. The roller set 60 is a commonly used sliding roller. At the same time, on one side of the long rod 31 close to the spiral blade 10, a set of diagonal rods 33 for connecting the long rod 31 and the short rod 32 is also provided. It can not only be used to fix the long rod 31 and the short rod 32, but also improve their connection strength. Furthermore, the long rod 31, the short rod 32 and the diagonal rods 33 together enclose a frame with an open structure on one side, so that the sliding support 40 can be conveniently installed on the guide rod frame 34, and it is also convenient to fix the spiral blade 10 on the sliding support 40.

[0041] The sliding support 40 is constructed as a tray-like structure. The motor 20 is fixed above the sliding support 34. The tail of the sliding support 40 is connected to the chain arranged on the long rod 31 through a connecting frame. And on one side of the long rod 31 close to the spiral blade 10, two guide rod frames 34 which are symmetrically arranged and cooperate with the sliding support 40 are also provided. That is, the guide rod frames 34 are arranged along the length direction of the long rod 31 and are fixedly welded to the long rod 31. The tail of the sliding support 40 is provided with a guide sleeve, which is sleeved on the guide rod frame 34 and can move up and down along the length direction of the guide rod frame 34. In order to facilitate observing the height position of the spiral blade 10, scales (the attached drawing is omitted) are provided on the upper section parts of the guide rod frames 34, which can be determined according to the actual situation and are not specifically limited here.

[0042] As Figure 3 shown, at the same time, in order to prevent the cut silt from splashing onto the gear set 50 after rotating with the spiral blade 10, a mud guard 35 is also provided at the end of the long rod 31 close to the roller set 60. The mud guard 35 not only facilitates improving the connection strength of the two long rods 31, but also can prevent the silt from splashing onto the gear set 50 and affecting the operation of the gear set 50.

[0043] As Figure 4 shown, the gear set 50 is fixed on the side surface of the long rod 31 away from the spiral blade 10 and is connected to the sliding support 40 through a chain; and the gear set 50 is arranged on the same side as the roller set 60.

[0044] On one side of the upper section part of the long rod 31 close to the gear set 50, a handrail 36 is also provided, and below the handrail 36, a handle 37 for driving the movement of the gear set 50 is also provided. Driving the handle 37 drives the chain on the gear set 50 to rotate, so that the spiral blade 10 can be driven to move up and down through the sliding support 40.

[0045] The hole cleaning device proposed in this application adjusts the position of the cleaning component through a hand-cranked structure. After the position is fixed, the motor 20 can drive the spiral blade 10 to automatically clean the sludge, and then it can clean the precast pipe piles with different pipe diameters and different depths. It can adjust and fix the positioning position at any time, and can ensure that the inner wall of the pipe pile is not damaged during the process of cleaning the soil; it can also clean the holes of pipe piles with different pipe diameters and different depths. When the elevation is determined, only relevant components need to be replaced to be used again, and only one construction worker is required for horizontal positioning to move the support frame to complete it.

[0047] S1. Push the support frame 30, and the roller group 60 can drive the cleaning component to move to the position of the pipe pile to be cleaned, and make the spiral blade 10 vertically downward through the support frame 30.

[0048] S2. After the position of the support frame 30 is placed horizontally and stably, drive the gear group 50 to rotate, and then drive the cleaning component to adjust the height position of the spiral blade 10 through the chain, so that the spiral blade 10 is directly above the hole to be cleaned on the pipe pile.

[0049] S3. After the position is adjusted, drive the spiral blade 10 to start cleaning the sludge through the motor 20.

[0050] S4. After the cleaning is completed, drive the sliding support 40 to retract to the original position through the gear group 50.

[0051] S5. Then drive the support frame 10 to move to the position of the next hole to be cleaned through the roller group 60.

[0052] Repeat steps S1 - S5 until all the pipe piles are finished with hole cleaning.
