Device for cleaning construction reserved hole

Abstract

The invention discloses a device for cleaning a construction reserved hole. According to the device for cleaning the construction reserved hole, gauze is in intermittent contact with the hole wall toconduct cleaning through cooperation of a gear stick and a sliding block, impurities in the reserved hole are pushed out integrally by cooperating with an air bag. The device is characterized in thatone end of a fixed cylinder is rotatably arranged at one end of a rotary cylinder, and the fixed cylinder communicates with the rotary cylinder; a through hole is formed in the middle of the other endof the fixed cylinder, a plurality of sets of square roles are formed in the rotary cylinder at equal intervals, and each set of square holes is composed of at least two square holes; the at least two square holes in the same set are distributed annularly, the distance between every two adjacent holes in the same set is equal, a driving wheel is arranged at the other end of the rotary cylinder, one end of a spline housing is arranged in the fixed cylinder, and connected with the inner wall of the fixed cylinder; and the other end of the spline housing penetrates out of the other end of the rotary cylinder through a fixing bearing, one end of a spline shaft is connected with a limiting block, the other end of the spline shaft penetrates through the spline housing and the through hole in the fixed cylinder sequentially and is connected with a fixing block.

Problems solved by technology

[0002] At present, in the field of building construction, it is often necessary to reserve some holes on the working surface of the wall to install parts such as anchor bolts. The reserved holes are usually directly exposed to the air. Because the construction environment is usually poor, there are often mud , Sand and gravel fall into the reserved holes and block the holes, making it difficult to feed in the subsequent construction anchor bolts and other parts. Usually, pre-cleaning work is required before installing anchor bolts and other parts in the reserved holes. Traditional reserved The hole cleaning method is to use a tool made of felt cloth or gauze wrapped around the steel rod and send it into the reserved hole. In order to make the side wall of the hole fully contact and rubbed, the number of layers of felt cloth wrapped around the hole is usually large and the thickness Larger, during the process of inserting the tool into the reserved hole, the felt cloth will send most of the debris in the reserved hole deeper into the hole. It is difficult to clean the debris in the deep hole, and it is usually abandoned. The cleaning effect is not good, and parts such as anchor bolts are directly installed, which is prone to the situation that the bolts cannot be completely sent into the reserved holes due to the blockage of debris in the deep hole. Now the commonly used hole cleaning device, such as the publication number CN205868975U, is disclosed A cleaning device for slender holes is developed. The device absorbs the sundries in the deep hole through the vacuum tube. It is difficult to clean up dry soil, etc., and auxiliary tools need to be used again for secondary cleaning, which is time-consuming and laborious, and the cleaning efficiency is low. Publication No. CN204497676U discloses a hole cleaner that is convenient for cable laying. Cleaning, when using this device to clean blind holes such as reserved holes, the sundries cleaned by the rotating blades in the depth of the hole will fall into the deeper hole, causing the sundries to pile up in the deep hole, which requires subsequent use of auxiliary equipment. The secondary cleaning work greatly reduces the cleaning efficiency, and is not suitable for cleaning the reserved holes in the building wall

[0003] Moreover, the above-mentioned devices do not consider that many of the reserved holes are drilled through the steel bars in the concrete on the building. Therefore, metal filings will accumulate in the reserved holes, and the metal filings are relatively heavy. place, so using the existing cleaning device, the cleaning effect is not good
