Description

Technical Field

[0001] This utility model belongs to the field of construction tool technology, specifically a telescopic joint type dust blowing device for rebar holes. Background Technology

[0002] Traditional dust-blowing devices for rebar installation holes have a fixed-length operating lever, which cannot be adjusted appropriately according to project needs, increasing the difficulty of cleaning dust from the rebar installation holes. In deep-hole rebar installation operations, it is difficult to ensure the equipment effectively contacts the bottom of the hole, making it impossible to blow away all the dust, thus increasing the difficulty of subsequent construction. Furthermore, due to the depth of the rebar installation holes and the limited space for dust blowing operations, large, high-powered air-blowing devices cannot be used.

[0003] Therefore, a construction device with a simple, retractable structure that is easy to construct and not limited by space or depth should be designed. Utility Model Content

[0024] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] like Figure 1 As shown, a telescopic joint type dust blowing device for rebar holes includes a backpack air compressor 1, a hose 2, a corner-type operating handle 3, and a telescopic operating rod 4.

[0027] The air outlet of the backpack air compressor 1 is connected to the air inlet of the corner operating handle 3 via a hose 2, and the air outlet of the corner operating handle 3 is connected to the air inlet of the telescopic operating rod 4.

[0028] like Figure 2As shown, the corner-type operating handle includes a handle body 3-1 and a handle 3-2. The handle 3-2 is inclined and connected to the handle body 3-1. The internal gas pipes of the handle body 3-1 and the handle 3-2 are connected. A gas control switch 3-3 is provided on the handle body 3-1. The gas control switch 3-3 controls the opening and closing of the gas pipe inside the corner-type operating handle.

[0029] like Figures 3-5 As shown, the retractable operating lever 4 is a three-section retractable operating lever, including an outer tube 4-1, a middle tube 4-2, and an inner tube 4-3. A sealing ring 4-4 ​​and a spring positioning ball 4-5 are provided between the outer tube 4-1 and the middle tube 4-2, and between the middle tube 4-2 and the inner tube 4-3. Taking the connection between the middle tube and the inner tube as an example, the spring positioning ball is set on the inner tube, and several recesses matching the spring positioning ball are provided on the middle tube. When the spring positioning ball extends or retracts to the recess, it pops out from the recess to achieve positioning and limitation. The sealing ring is sleeved on the inner tube, with one side contacting the outer surface of the inner tube and the other side contacting the inner surface of the middle tube, sealing the gap between the middle tube and the inner tube. The connection between the outer tube and the middle tube is the same as the connection between the middle tube and the inner tube.

[0030] The corner-type operating handle 3 and the retractable operating rod 4 are connected by threads or snaps.

[0031] The hose 2 and the corner-type operating handle 3 are connected by threads or snaps.

[0032] The backpack air compressor 1 has a cross-strap 1-1.

[0033] The hose 2 is made of rubber.

[0034] The retractable operating lever 4 is made of stainless steel.

[0035] Because the retractable operating rod of this utility model has different types of anchor hole diameters, and the anchor hole diameters are mostly small, a stainless steel retractable tube fitting that is tightly connected, can be freely extended and retracted, is compact in size, and is sturdy is selected for the operating rod.

[0036] The rubber sealing ring of this utility model addresses the issue that insufficient airtightness at the telescopic connection of the telescopic structure of the telescopic operating rod can lead to air leakage during blow-through. Therefore, a rubber ring of the same diameter is nested inside the telescopic connection of the telescopic pipe to ensure good airtightness of the telescopic operating rod and optimize blow-through efficiency.

[0037] The backpack air compressor of this utility model addresses the problem that operators need to constantly change their working position and angle during the construction of rebar anchoring and hole cleaning projects in order to ensure the quality and efficiency of hole cleaning. Therefore, the terminal air compressor of the hole cleaning device adopts a small, lightweight, and portable backpack air compressor to solve the problem that construction personnel need to frequently move their positions during the construction of rebar anchoring and hole cleaning, thereby greatly improving the efficiency and ease of operation of hole cleaning.

[0038] The hose of this utility model is made of rubber hose or stainless steel hose. Due to the operational needs during the construction process, it is necessary to maintain operational flexibility at all times during the rebar installation and hole cleaning construction. Therefore, the connection between the operating rod and the air compressor needs to be sealed with an adjustable hose to ensure the comfort and flexibility of the construction workers during the construction process.

[0039] This utility model features a corner-type operating handle. Because the rebar holes are quite deep, during the cleaning process, the operator must hold the operating rod perpendicular to the concrete surface and be close to the hole. This makes the operator susceptible to dust and debris accumulation during cleaning, and holding the operating rod perpendicular to the concrete surface can cause operator fatigue. Therefore, the operating rod is designed with a corner, and a gas control switch is installed on the handle body for easier operation. This maximizes ease of operation and operator comfort, and improves construction efficiency and quality.

[0040] Installation of the telescopic joint type dust blowing device for rebar anchoring holes:

[0041] Before installing the equipment, check the airtightness of all components to ensure that each component is airtight and free from defects such as air holes, misalignment, or insufficient performance, so as to ensure the normal and effective progress of subsequent construction.

[0042] Connect the rubber hose to the air compressor's outlet port using either a threaded or snap-fit ​​connection, and seal the connection with a rubber sealing ring of the same diameter to ensure a tight fit. Connect the other end of the rubber hose to the air inlet port of the corner operating handle, again sealing the connection with a rubber sealing ring of the same diameter to ensure a tight fit and prevent leaks or loosening. Connect the air inlet port of the telescopic operating lever to the air outlet port of the corner operating handle using either a threaded or snap-fit ​​connection, again sealing the connection with a rubber sealing ring of the same diameter to ensure a tight fit and prevent leaks or loosening. Then, attach the cross-straps at both ends of the air compressor to the worker and secure it using a diagonal, cross-binding method to ensure effective and stable operation of the air compressor during construction.

[0043] Debugging of the telescopic joint type rebar hole dust blowing device of this utility model:

[0044] Check the airtightness and safety performance of the installed operating lever device, and perform equipment debugging. After debugging, turn on the air compressor power, test the performance and operation of the corner-type operating lever switch, turn off the gas control switch of the corner-type operating lever, and check whether there is gas flowing out of the air outlet of the operating lever; then turn on the gas control switch of the operating lever and test whether the gas blowing out of the air outlet of the operating lever is stable and smooth. Extend the operating lever layer by layer and test the air blowing situation of the top air outlet to ensure that the airtightness of the connection of each layer of pipe is good, the blowing pressure is stable and continuous, and there is no leakage, interruption, pipe misalignment, or sliding jamming. After successful debugging, according to the actual project conditions, extend the telescopic operating lever to a suitable length to perform the blowing operation.

[0045] The process of cleaning the anchor holes in this utility model:

[0046] To prevent incomplete cleaning and residual dust in the hole due to excessive depth of the anchoring hole and excessive dust and debris, the operating rod should be slowly advanced during the blowing process. The rod should be pushed into the anchoring hole at a uniform speed until the tip touches the bottom, pausing briefly to ensure dust is blown out. During blowing, the tip of the operating rod should be checked regularly for dust backflow blocking the air outlet. If dust backflow blocks the air outlet, it should be cleared promptly to prevent uneven airflow and incomplete cleaning.

[0047] Repeat the rebar drilling process 3 to 5 times until there is no dust or debris in the hole, and finally the hole wall is free of dust, oil, and organic impurities.

[0048] After the blowing process is completed, remove the operating rod from the rebar hole. Check the connection of the operating rod for damage or air leaks, and check the top of the operating rod for dust blockage. Extend the operating rod to its maximum length and perform an air blowing operation to ensure that no debris or dust remains inside the operating rod. Simultaneously check that the gas control switch operates smoothly and effectively. After confirming everything is correct, retract the operating rod to its shortest position and turn off the gas control switch and the power to the air compressor. Finally, promptly clean the area around the concrete rebar hole at the construction site to prevent dust and debris from re-entering the rebar hole and affecting subsequent construction progress.

[0049] For any content not described in detail in this utility model, conventional technical knowledge in the field can be used.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
