Description

Technical Field

[0001] The utility model relates to the technical field of equipment for cleaning a pile foundation hole, in particular to a cleaning tool for a pile foundation hole. Background Art

[0002] The foundation pile hole is a hole for pouring concrete piles to reinforce the underground foundation and improve the bearing capacity and earthquake resistance of the building foundation. After the foundation pile hole is drilled, a steel cage is put into the hole, and then concrete is poured. After the concrete solidifies, it becomes a foundation pile in close contact with the surrounding soil layer. This is a method widely used in modern construction. After the pile foundation hole is dug, in order to ensure the flatness of the inner wall of the pile foundation hole, it is necessary to use a hole cleaning device to clean the inner wall of the hole to ensure the stability of the pile foundation in the later stage.

[0003] However, the existing pile foundation hole cleaning device is generally a device similar to a hand-held punching machine. When in use, it uses a rotating spiral drill rod to rotate in the pile foundation hole to clean the inner wall of the pile foundation hole. Therefore, it is not difficult to see that when in use, it cannot be applied to pile foundation holes of different hole diameters, and it is impossible to meet the requirement that one hole cleaning device is applicable to the cleaning operation of pile foundation holes of different hole diameters. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide a pile foundation hole cleaning tool, which, when used, can be competent for the cleaning work of pile foundation holes with different hole diameters.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is:

[0006] A hole cleaning tool for pile foundation holes, comprising a frame, a motor, a transmission shaft, a barrel shaft, a telescopic rod structure, a scraper and a collecting trough; the frame is an inverted U-shaped plate structure, the motor is mounted and fixed on the top of the frame, and the output shaft end is fixedly connected with the transmission shaft, the transmission shaft is a non-cylindrical shaft structure, the barrel shaft is movably sleeved on the transmission shaft, and after passing through the top plate of the frame, it is threadedly connected to the top plate, at least two scrapers are evenly arranged along the circumference of the barrel shaft, and are respectively connected to the bottom of the barrel shaft through the telescopic rod structure, the bottom end of the barrel shaft is detachably mounted with a collecting trough, the collecting trough is a disc trough structure, and the movement range of the scraper is larger than the top view area of ​​the collecting trough.

[0007] As an improvement, a threaded sleeve is threadedly sleeved on the barrel shaft, and the threaded sleeve penetrates and is integrally formed and arranged on the top plate of the frame, so that the threaded connection between the barrel shaft and the frame is more stable.

[0008] As an improvement, the telescopic rod structure includes a barrel rod, a movable inner rod and a bolt; the barrel rod is movably sleeved on the movable inner rod, and one end is fixedly connected to the outer wall of the barrel shaft, one end of the movable inner rod is fixedly connected to the scraper, and is fixed to the inner side of the barrel rod by a bolt, a screw hole matching the bolt is provided at the free end of the barrel rod, a positioning screw hole matching the bolt is provided on the side wall of the movable inner rod, and a plurality of positioning screw holes are evenly arranged along the axial direction of the movable inner rod. The distance between the scraper and the barrel shaft is adjustable, so that the new type can be applied to pile foundation holes of different hole diameters.

[0009] As an improvement, a threaded sleeve is integrally formed at the bottom of the collecting tank, and the threaded sleeve is threadably sleeved on the outer wall of the bottom of the shaft, so that the collecting tank can be easily assembled and disassembled, thereby facilitating its replacement.

[0010] It is worth mentioning that the motor used in this technical solution is an existing device well known to those skilled in the art, and its use and control methods are all existing technologies.

[0011] The advantages of the utility model compared with the prior art are:

[0012] 1. When the present invention is in use, the motor can drive the barrel shaft to rotate and move up and down at the same time. It can rotate clockwise and move downward at the same time, thereby driving each scraper to clean the pile foundation hole. On the contrary, the scraper will withdraw from the pile foundation hole, and the hole cleaning work is completed. And through the design of the telescopic rod structure, the distance between the scraper and the barrel shaft can be adjusted, so that the present invention can be competent for the cleaning of pile foundation holes of different diameters within a certain range.

[0013] 2. When the present invention is in use, most of the soil on the inner wall of the pile foundation hole cleaned by the scraper will be collected in the collecting trough, and can be easily cleaned out after the hole cleaning work is completed; and the collecting trough is a replaceable structure, so when adjusting the distance between the scraper and the cylinder axis, it is convenient to replace the collecting troughs of different radius sizes for matching use.
