Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically a mobile pneumatic lifting auxiliary device for drilling holes in concrete roof slabs. Background Technology

[0002] In the renovation or reinforcement of building construction, drilling is often required on the already poured concrete slab, for example, to install rebar in structural columns or to install post-installed embedded parts. The quality of the holes (especially the verticality of the holes) directly affects the anchorage strength of the rebar or embedded parts, and thus the safety of the overall structure. Therefore, strict control over the quality of the holes is a core aspect of the construction process.

[0003] Currently, there are two main methods for drilling holes in roof slabs: The first is to erect mobile scaffolding, with workers standing on the scaffolding and using hand-held impact drills for high-altitude work. This method has significant drawbacks: extremely low efficiency, time-consuming and labor-intensive scaffolding erection and movement, the risk of falls from heights, and difficulty in ensuring the verticality of the drilled holes due to manual hand-held drilling, resulting in poor quality consistency. The second method is to use simple support rods to prop the impact drill against the roof slab for drilling. While this method avoids working at heights, it still suffers from low construction efficiency, laborious operation, and insufficient stability of the support rods, making it difficult to precisely control the verticality of the drilled holes.

[0004] In summary, the existing technology lacks a dedicated device that can simultaneously ensure drilling quality, improve construction efficiency, guarantee operational safety, and reduce labor intensity. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a mobile pneumatic lifting auxiliary device for drilling concrete roof slabs. This device aims to solve the problems of existing roof slab drilling methods, such as difficulty in ensuring hole verticality, low construction efficiency, safety risks associated with high-altitude operations, and high labor intensity.

[0006] The technical solution adopted by this invention to solve its technical problem is: A portable pneumatic lifting auxiliary device for drilling concrete roof slabs includes an impact drill, a frame, a lifting system, and a pneumatic system. The lifting system and the pneumatic system are respectively mounted on the frame and connected to each other. The impact drill is mounted on the lifting system. The pneumatic system provides power to the lifting system to raise and lower it.

[0007] Compared with the prior art, the beneficial effects of the present invention are: This invention, through the configuration of a frame, lifting system, and pneumatic system, allows for precise and stable adjustment of the impact drill's height, thus meeting drilling requirements and improving work efficiency. Especially when performing high-altitude operations, using this device for roof drilling eliminates the need for workers to perform such work, reducing their workload and mitigating potential safety issues associated with high-altitude work, thereby improving construction safety. Furthermore, the coordinated operation of the pneumatic and lifting systems enhances drilling quality, laying a solid foundation for subsequent rebar installation.

[0008] As a preferred embodiment, a further technical solution of the present invention is: Preferably, the frame includes a movable base, legs fixed to the base, and clamping tubes vertically fixed to the legs; The pneumatic system includes an air compressor and a pneumatic lifting unit connected to it, the pneumatic lifting unit being driven by the air compressor; The lifting system includes a lifting rod, a lifting bracket, and an impact drill bracket. The lower end of the lifting rod is fitted inside the jacket tube and slides with the jacket tube. The lower part of the lifting rod is connected to the output end of the pneumatic lifting unit through the lifting bracket. The upper end of the lifting rod is equipped with an impact drill bracket.

[0009] Preferably, the bottom of the movable base is equipped with casters.

[0010] Preferably, the pneumatic lifting unit is a cylinder, the cylinder body is fixed on a movable base, and the output end of the cylinder is connected to the lifting bracket.

[0011] Preferably, the impact drill support includes a base plate and a clamp. A limiting hole is formed in the center of the base plate, and the end of the impact drill away from the drill bit is inserted into the limiting hole. The clamp is placed at the top of the lifting rod, and the end of the impact drill body near the drill bit is locked to the lifting rod by bolts on the clamp. Attached Figure Description

[0013] The present invention will be further illustrated below with reference to specific embodiments. The purpose of this illustration is solely to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0014] like Figure 1As shown, a mobile pneumatic lifting concrete slab drilling auxiliary device consists of an impact drill 1, a frame, a lifting system, and a pneumatic system. The lifting system and the pneumatic system are respectively placed on the frame and connected to each other. The impact drill 1 is placed on the lifting system. The pneumatic system provides power to the lifting system to make the lifting system rise and fall.

[0015] The frame consists of a movable base 2, support legs 3 fixed to the movable base 2, and a clamping tube 4 vertically fixed to the support legs 3. The movable base 2 adopts a steel frame structure, and four universal wheels 5 with built-in brakes are installed at the bottom of the movable base 2 as load-bearing wheels; the support legs 3 are welded from rectangular steel tubes and are fixedly placed on the upper end of the movable base 2, providing sufficient support strength for the entire device; the clamping tube 4 is a round steel tube, the lower end of the clamping tube 4 is fixedly connected to the movable base 2, and the upper part of the clamping tube 4 is welded and fixed to the support legs 3.

[0016] The pneumatic system consists of an air compressor 6 and a pneumatic lifting unit 7. The air compressor 6 can be a commercially available small air compressor 6. The pneumatic lifting unit 7 is a cylinder. The cylinder body is mounted on the support leg 3. The cylinder body is also connected to the air compressor 6 through a pipeline. The air compressor 6 serves as a power source, providing compressed air to the pneumatic lifting unit 7 to drive the cylinder to perform telescopic movements.

[0017] The lifting system consists of a lifting rod 8, a support bracket 9, and an impact drill bracket 1. The lifting rod 8 is a solid round steel rod, and its lower end is fitted inside the jacket tube 4 with a clearance fit. The support bracket 9 is fixed to the lower part of the lifting rod 8, and the top end of the lifting rod 8 is connected to the support bracket 9. The bottom end of the support bracket 9 is connected to the output end of the pneumatic lifting unit 7. In this embodiment, the support bracket 9 is cut from a thick steel plate, and the top of the support bracket 9 is fixedly connected to the lifting rod 8 by a diagonal brace. By adding the diagonal brace, the connection strength between the support bracket 9 and the lifting rod 8 is enhanced.

[0018] The impact drill 1 bracket is placed at the top of the lifting rod 8. In this embodiment, the impact drill 1 bracket consists of a base plate 101 and a clamp 102. A limiting hole is opened in the center of the base plate 101, and the end of the impact drill 1 away from the drill bit is inserted into the limiting hole. The clamp 102 is placed at the top of the lifting rod 8, and the end of the impact drill 1 body close to the drill bit is connected to the impact drill 1 bracket by bolts on the clamp 102.

[0019] In the specific application of this device, the construction personnel first determine the location of the rebar to be installed according to the actual drawings, then move the device below the location to be installed, and then lock the casters 5; next, install the impact drill 1 on the impact drill 1 bracket and connect the power supply. The impact drill 1 is controlled to be turned on and off by a remote control switch; start the pneumatic system, and the air compressor 6 drives the pneumatic lifting unit 7 to push the support bracket 9 up, thereby causing the support bracket 9 to push the lifting rod 8 up along the jacket tube 4 to the specified height; start the impact drill 1 to start drilling. At the same time as drilling, the lifting rod 8 is driven to rise by the air compressor 6 under the limiting and guiding effect of the jacket tube 4 to meet the drilling depth requirements; when the drilling reaches the predetermined depth, first turn off the impact drill 1, and then control the pneumatic lifting unit 7 to descend through the pneumatic system, so that the lifting rod 8 drives the impact drill 1 to descend smoothly to the initial position; finally, move the entire device to the next hole position and repeat the above operation.

[0020] In this invention, the jacket tube, in addition to fixing the cylinder platform, also serves as a guide for the lifting rod, ensuring that the lifting rod and impact drill are perpendicular to the working surface. The pneumatic lifting unit and the jacket tube work together to form a precise limiting and guiding structure, thereby better ensuring construction quality and providing a good working foundation for subsequent rebar installation. The movable base and the lifting rod lifted by a pneumatic system greatly improve work efficiency and reduce the labor intensity of workers in a large number of drilling operations. Especially in buildings with high ceilings, when using this device for roof drilling operations, construction workers do not need to work at heights, thereby reducing the risk of construction operations.

[0021] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the invention. All equivalent changes made based on the description and drawings of the present invention are included within the scope of the present invention.
