Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and particularly relates to a hole cleaning device for post-inserted bars of construction columns. Background Technique

[0002] The technology of post-inserted bars in construction columns is a method of implementing post-inserted bar reinforcement on existing construction column structures. It drills holes, injects glue, and inserts steel bars on the column body, tightly connecting the newly added steel bars with the original column body, thereby improving the bearing capacity, seismic performance, and overall stability of the column body.

[0003] Preparation stage: Conduct a detailed inspection and analysis of the construction column to determine the positions and scopes that need to be reinforced. At the same time, prepare the required materials and equipment, including high-strength post-inserted bar glue, steel bars, drilling equipment, glue injection tools, etc.

[0004] Drilling stage: Drill a certain number of post-inserted bar holes on the construction column according to the design requirements. When drilling, ensure that the hole diameter and hole depth meet the design requirements, and at the same time avoid causing excessive damage to the column body.

[0005] Hole cleaning stage: After drilling, it is necessary to clean the inside of the hole to ensure that there is no dust, debris, etc. inside the hole. The hole cleaning method can adopt high-pressure air blowing, vacuum cleaner suction, etc.

[0006] Glue injection stage: Inject high-strength post-inserted bar glue into the post-inserted bar holes. When injecting glue, control the amount of glue injection to ensure that the hole is filled with glue, and at the same time avoid the glue flowing out. After the glue injection is completed, wait for the glue to cure.

[0007] Post-inserted bar stage: Before the glue cures, insert the steel bars into the post-inserted bar holes. When inserting, ensure that there is glue between the steel bars and the hole wall, and at the same time avoid the steel bars from bending or being misaligned.

[0008] Curing and maintenance stage: After the steel bars are inserted, wait for the glue to completely cure. The curing time depends on factors such as the performance of the glue and the ambient temperature. After curing is completed, carry out necessary maintenance and protection.

[0009] Existing post-inserted bar hole cleaning structures often use a brush for cleaning, and clean the inner wall by rotating to remove the impurities attached to the inner wall of the post-inserted bar holes. However, the post-inserted bar holes are not thoroughly cleaned, or use air flow for cleaning. This cleaning method is difficult to ensure that the inner wall of the hole is smooth. Based on this, it is necessary to research a hole cleaning device for post-inserted bars of construction columns. Content of the Utility Model

[0010] In view of this, the purpose of the utility model is to provide a hole cleaning device for post-inserted bars of construction columns, which effectively solves the problems of incomplete cleaning and troublesome operation existing in the existing post-inserted bar hole cleaning devices.

[0011] To achieve the above object, the technical solution adopted by the utility model is: a hole cleaning device for planting steel bars in construction columns, which includes an air flow dust cleaning component and a brush body cleaning component. The air flow dust cleaning component includes a motor, a rotating shaft, a housing and an air duct; the air duct is communicated with the inner cavity of the housing through a connecting pipe. A rotating shaft is arranged in the housing, the rotating shaft extends out of the housing and is drivingly connected with the motor, a fan blade is arranged on the rotating shaft, and side air holes and end air holes are respectively arranged on the side wall and the end of the air duct; the brush body cleaning component includes a brush body, an upper rotating sleeve, a lower rotating sleeve, a driven gear and a driving gear. The upper rotating sleeve and the lower rotating sleeve are respectively rotatably sleeved on the upper and lower parts of the air duct. Among them, a driven gear is fixedly sleeved on the upper rotating sleeve, the driving gear is fixed on the rotating shaft and meshes with the driven gear, and the brush body is fixed between the upper rotating sleeve and the lower rotating sleeve.

[0012] Further, the brush body includes a fixed shaft, a fixed seat and a brush. The fixed shaft is fixed on the upper rotating sleeve and the lower rotating sleeve, the fixed seat is fixed on the fixed shaft, and the brush is fixed on the fixed seat and is located outside the upper rotating sleeve and the lower rotating sleeve.

[0013] Further, a shaft seat is arranged on the air duct, and the lower rotating sleeve and the lower rotating sleeve are rotatably arranged on the shaft seat.

[0014] Further, a conical head is arranged at the front end of the air duct, and the end air hole is opened in the middle of the conical head and is communicated with the inner cavity of the air duct.

[0015] Further, it also includes a frame body. The motor and the rotating shaft are both installed on the frame body, and a handle is arranged at the rear end or side of the frame body.

[0016] Further, a protective cover and a handle are arranged on the frame body. The protective cover wraps the motor, the housing, the driving gear and the driven gear, and the protective cover is in rotational fit with the upper rotating sleeve.

[0017] Further, the rotating shaft is rotatably arranged on the upper and lower parts of the housing through a sealed bearing and is drivingly connected with the motor outside the housing.

[0018] The beneficial effects of the above technical solution are: the utility model adopts a structure of synchronously cleaning the steel bar planting holes by air flow and brush body in terms of structure. The brush body is arranged outside the air pipe and is rotated by the motor rotating shaft. The rotation drives the fan blade and the driving gear to rotate. Through this matching structure, two actions of air flow transportation and gear rotation can be realized. The fan blade rotation forms an air flow, and the gear rotation forms a rotational power. In order to ensure the transmission relationship, the driving gear is configured as a large gear and the driven gear is a small gear, and the transmission ratio is matched to ensure the rotation speed of the fan blade, provide a relatively strong air flow, and at the same time ensure the rotational power of the brush body to ensure the cleaning effect.

[0019] Structurally, an upper rotating sleeve and a lower rotating sleeve are arranged on the air pipe, and a brush body structure is arranged on the upper rotating sleeve and the lower rotating sleeve. The upper rotating sleeve is driven by a gear to rotate, so that the brush body rotates on the outer side of the air pipe. The internal air flow is discharged from the side and end of the air pipe, and the inner wall and bottom of the rebar planting hole are cleaned specifically. At the same time of the brush body cleaning, air flow cleaning is completed. The construction is convenient, and the cleaning effect and cleaning efficiency of the rebar planting hole are greatly improved.

[0020] The utility model has a novel structure. The air flow generation and rotation drive are realized by one motor. The structure is simple, the cost is low, it is convenient to maintain, and the structure is compact.

[0021] The utility model combines an air flow dust cleaning component and a brush body cleaning component. The motor drives the rotating shaft to rotate, so that the fan blades generate air flow, and the air flow is guided into the hole through the side air holes and end air holes, effectively blowing and removing the dust and sundries in the hole. At the same time, the brush body rotates synchronously under the drive of the rotating shaft, further brushing the residues on the hole wall, ensuring the high efficiency of dust cleaning. It has beneficial effects such as high-efficiency dust cleaning, simple and flexible operation, reasonable structural design, convenient and safe use, and strong adaptability, and can effectively improve the efficiency and quality of the dust cleaning operation and reduce the construction cost.

Detailed Embodiment

[0029] The following further describes the utility model in detail in conjunction with the drawings and specific embodiments:

[0030] Example 1. This example aims to provide a hole cleaning device for structural column rebar embedding, which is mainly used for cleaning holes in structural column rebar embedding. Traditional single cleaning methods, such as only using a brush for rotating cleaning, or only relying on airflow for cleaning, have the problems of single cleaning means, poor cleaning effect and cumbersome operation. Based on this, this example provides a hole cleaning device for structural column rebar embedding.

[0031] like Figure 1 As shown in , a hole cleaning device for structural column reinforcement planting includes an airflow cleaning component and a brush cleaning component. In this embodiment, the airflow cleaning component is used to generate airflow and perform airflow cleaning on the structural column reinforcement planting hole. The brush cleaning component is used to perform rotary cleaning on the inside of the structural column with a rotating brush body. This embodiment combines the airflow cleaning component and the brush cleaning component. The motor drives the shaft to rotate, so that the fan blades generate airflow, and the airflow is directed into the hole through the side air holes and the end air holes, effectively blowing away and removing dust and debris in the hole. At the same time, the brush body rotates synchronously under the drive of the shaft to further brush away the residue on the hole wall, ensuring the high efficiency of cleaning.

[0032] In the specific implementation structure, the airflow cleaning component includes a motor 1, a rotating shaft 3, a shell 2 and an air duct 6; the air duct 6 is connected to the inner cavity of the shell 2 through a connecting pipe, and a rotating shaft 3 is arranged in the shell 2, the rotating shaft 3 extends out of the shell 2 and is transmission-connected to the motor 1, and a fan blade 4 is arranged on the rotating shaft 3; Figure 1 and Figure 5 As shown in the figure, the shell 2 is a hollow shell 2 structure with closed two ends, an air inlet hole is provided at the upper part, and an exhaust hole is provided at the lower part. The fan blades 4 are arranged between the air inlet hole and the exhaust hole. The rotating shaft 3 is rotatably arranged at the upper and lower parts of the shell 2 through sealed bearings, and is transmission-connected with the motor 1 outside the shell 2. The external motor 1 is used to drive the rotating shaft 3, and the fan blades 4 are rotated to generate airflow, which is transported to the air duct 6 through the exhaust hole.

[0033] The air duct 6 is structurally a hollow circular structure as a whole. A conical head 7 is provided at the front end of the air duct 6 . The end air hole 9 is opened in the middle of the conical head and communicated with the inner cavity of the air duct 6 .

[0034] The side walls and ends of the air duct 6 are respectively provided with side wind holes 8 and end wind holes 9. There are multiple groups of side wind holes 8 on the inner wall of the air duct 6, and they are respectively facing different directions. The side wind holes 8 can face the inner wall of the rebar hole to achieve airflow cleaning of the side wall of the rebar hole; and the end wind holes 9 face the bottom of the rebar hole and perform targeted cleaning on the bottom of the rebar hole. By configuring the side wind holes 8 and the end wind holes 9, all-round cleaning of the rebar hole can be achieved.

[0035] The brush body cleaning component includes a brush body 14, an upper rotating sleeve 11, a lower rotating sleeve 12, a driven gear 13 and a driving gear 10. The upper rotating sleeve 11 and the lower rotating sleeve 12 are respectively rotatably sleeved on the upper and lower parts of the air duct 6. In a specific fixing method, a shaft seat is provided on the air duct 6, and the lower rotating sleeve 12 and the lower rotating sleeve 12 are rotatably arranged on the shaft seat, so that the upper rotating sleeve 11 and the lower rotating sleeve 12 are rotationally configured on the air duct 6.

[0036] A driven gear 13 is fixedly sleeved on the upper rotating sleeve 11. The driving gear 10 is fixed on the rotating shaft 3 and meshes with the driven gear 13. The brush body 14 is fixed between the upper rotating sleeve 11 and the lower rotating sleeve 12.

[0037] During implementation, the brush body 14 includes a fixed shaft 141, a fixed seat 142 and a brush 143. The fixed shaft 141 is fixed on the upper rotating sleeve 11 and the lower rotating sleeve 12. The fixed seat 142 is fixed on the fixed shaft 141. The brush 143 is fixed on the fixed seat and is located outside the upper rotating sleeve 11 and the lower rotating sleeve 12.

[0038] The upper rotating sleeve 11 and the lower rotating sleeve 12 in the brush body 14 cleaning component are linked with the rotating shaft 3 through the driving gear 10 and the driven gear 13, so that the brush body 14 can automatically rotate with the rotation of the rotating shaft 3 without additional operation.

[0039] During use, the operator inserts the air duct 6 and the brush body 14 into the rebar planting hole, and then starts the motor 1. The rotation of the motor 1 drives the rotation of the rotating shaft 3. The rotation of the rotating shaft 3 drives the rotation of the fan blade 4 and the driving gear 10 at the lower part. The rotation of the fan blade 4 generates air flow. At the same time, the cooperation of the driving gear 10 and the driven gear 13 drives the upper rotating sleeve 11 to rotate around the air duct 6. Thus, the upper rotating sleeve 11, the lower rotating sleeve 12 and the brush body 14 rotate around the air duct 6. The air duct 6 is in a fixed state, and the brush body 14 is in a rotating state. The brush body 14 is a soft deformable structure. It penetrates into the rebar planting hole for rotary cleaning. At the same time, the inner wall of the rebar planting hole is cleaned by the side air holes evenly distributed at multiple angles. The structure of synchronously cleaning the rebar planting hole with air flow and the brush body 14 is adopted. The brush body 14 is arranged outside the air pipe, and the motor 1 rotating shaft 3 is used for rotation. The rotation drives the rotation of the fan blade 4 and the driving gear 10. Through this cooperation structure, two actions of air flow transportation and gear rotation can be realized. The rotation of the fan blade 4 forms air flow, and the rotation of the gear forms rotation power. In order to ensure the transmission relationship, the driving gear 10 is configured as a large gear, and the driven gear 13 is a small gear. The transmission ratio is matched to ensure the rotation speed of the fan blade 4, provide relatively strong air flow, and at the same time ensure the rotation power of the brush body 14 to ensure the cleaning effect.

[0040] Embodiment 2. This embodiment is basically the same as Embodiment 1, except that a frame structure is configured on the basis of Embodiment 1.

[0041] For the convenience of operation, in this embodiment, both the motor 1 and the rotating shaft 3 are installed on the frame body 15, and a handle 16 is provided at the rear end or side of the frame body 15. Hold the handle 16 and place the air duct at the front end into the rebar planting hole.

[0042] A protective cover 17 and a handle 16 are provided on the frame body. The protective cover wraps the motor 1, the housing 2, the driving gear 10 and the driven gear 13. The protective cover 17 is in rotational fit with the upper rotating sleeve 11.

[0043] This embodiment is equipped with a frame body and a handle, enabling the operator to conveniently hold or fix the device for dust cleaning operations. The design of the protective cover effectively protects key components such as the motor 1, the housing 2, the driving gear 10 and the driven gear 13, preventing them from being damaged or contaminated during the operation. At the same time, the rotational fit between the protective cover and the upper rotating sleeve 11 also ensures that the brush body 14 will not be hindered during rotation.

[0044] The above-described embodiments of the present invention do not constitute a limitation to the protection scope of the present invention. The basic concept of the present invention lies in the combination of the air flow dust cleaning component and the brush body cleaning component. By driving the rotating shaft to rotate through the motor, the fan blades generate air flow, and the air flow is guided into the hole through the side air holes and the end air holes, effectively blowing and removing the dust and debris in the hole. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
