Technical Field

[0001] This invention relates to the field of drilling equipment for building construction, specifically a vertical drilling device for embedded plates. Background Technology

[0002] In the construction process, drilling of embedded plates, small prefabricated components, formwork and aluminum alloy profiles is a large-scale process with high precision requirements. The verticality of the drilling directly affects the installation quality and connection strength of subsequent components.

[0003] Currently, drilling operations at construction sites are mostly completed using large production line equipment or handheld electric drills. Large drilling equipment is bulky, inconvenient to move, and significantly limited by the terrain and space of the construction site, making it difficult to flexibly adapt to scattered on-site drilling needs. Handheld electric drills rely on manual control of the drilling direction, making it difficult to guarantee verticality. Long-term operation can easily lead to worker fatigue, resulting in low construction efficiency. Furthermore, the wobbling of the electric drill can cause safety hazards such as scratches, making it difficult to meet the needs of efficient and precise on-site drilling. Summary of the Invention

The vertical support rectangular tubes and inclined support rectangular tubes are fixedly connected by stiffening steel plates and matching bolts to form a vertical stable frame. The lifting transmission mechanism includes a starting rod, a transmission shaft, a transmission gear, a gear guide rail, a transmission chain, and a horizontal guide frame. The transmission chain is welded and fixed to the side of the gear guide rail. The transmission gear meshes with the transmission chain. The starting rod is connected to the transmission gear through the transmission shaft. Rotating the starting rod can drive the transmission gear to roll vertically along the transmission chain, thereby driving the horizontal guide frame to move vertically in a straight line. The electric drill clamping mechanism includes a tail ring cutter adjuster and an end ring cutter adjuster, both of which are fixedly installed on the horizontal guide frame. They respectively clamp the tail of the electric drill and the end of the drill bit, fixing the electric drill in a vertical position on the horizontal guide frame and moving up and down synchronously with the horizontal guide frame. The height adjustment mechanism includes a vertical support steel pipe and a steel pipe limit adjuster. The vertical support steel pipe is arranged vertically, and the extension height is locked by the steel pipe limit adjuster to provide vertical support and working height positioning for the horizontal guide frame.

[0006] Preferably, the bottom support assembly includes a tray, a steel pad, and a spring. The spring is disposed between the lower end of the vertical support steel pipe and the steel pad, and the steel pad is laid flat on the upper surface of the tray. The spring is used to buffer the upper force during drilling operations and reduce the vibration of the device during operation.

[0007] Preferably, the clamping inner diameter of the tail ring cutter adjuster is adjustable to adapt to electric drills with different tail sizes; the clamping inner diameter of the end ring cutter adjuster is adjustable to adapt to different specifications of drill rods and electric drill front end sizes, so as to realize the quick installation, disassembly and secure clamping of the electric drill.

[0008] Preferably, a rolling sleeve is fitted onto the rod body of the transmission shaft.

[0009] Preferably, the two sides of the rolling sleeve are axially limited by locking nuts to ensure smooth rotation of the transmission shaft and reduce wear during transmission.

[0010] Preferably, the starting rod is made of round steel rod and has a grip section at the end of the rod. Power is input by manually rotating the starting rod, and the rotational motion is converted into the vertical linear feed motion of the horizontal guide frame through the meshing of the transmission gear and the transmission chain.

[0011] Preferably, the horizontal guide frame is made of guide frame steel pipe, and the frame body has reserved installation positions for fixing the electric drill clamping mechanism and transmission components, so as to ensure the verticality of the electric drill after installation.

[0012] Preferably, the bottom of the vertical support rectangular tube is provided with a rust-proof pad to prevent the bottom of the frame from directly contacting the working surface and causing rust, thus extending the service life of the device.

[0013] Preferably, the support frame is provided with a fixed round steel bar and a cable routing ring for routing and securing the electric drill cable, so as to prevent the cable from getting tangled and interfering with the drilling operation.

[0014] Preferably, the inclined support rectangular tube is inclinedly connected between the vertical support rectangular tube and the bottom support component, and together with the vertical support rectangular tube and the bottom support component, it forms a triangular stable structure, thereby improving the overall anti-overturning stability of the device.

[0015] (III) Beneficial Effects This invention provides a device for vertical drilling of embedded plates. It has the following advantages: 1. This invention employs a gear-chain meshing manual transmission structure, coupled with a ring cutter clamping mechanism arranged coaxially, to achieve rigid vertical guiding feed of the electric drill. Through the transmission cooperation between the fixed chain and the rolling gear, manual rotational power is converted into smooth vertical linear motion; combined with a dual-point coaxial clamping structure to hold and lock the electric drill's posture, the verticality of the drilling is guaranteed from the structural source, effectively solving the pain points of large drilling direction deviation and difficulty in controlling accuracy of traditional handheld electric drills. Precise drilling operations can be completed without the need for external power equipment, making it suitable for the high-precision drilling needs of scattered workpieces on construction sites.

[0016] 2. This invention can be manufactured using commonly available steel and standard parts found on construction sites. It is lightweight, easy for a single person to handle and move, and can flexibly adapt to scattered drilling operations at different workstations. Two sets of adjustable ring cutter adjusters are compatible with various specifications of electric drills and drill rods, and are easy to install and remove. Combined with a lockable height adjustment structure, the working height and drilling depth can be quickly adjusted, adapting to embedded plates, templates, and other workpieces of different thicknesses. Manual transmission operation saves effort, effectively reducing the labor intensity of operators and significantly improving the efficiency of single-hole operations.

[0017] 3. This invention adopts a triangular stable frame structure, which has excellent anti-overturning performance and strong overall stability during operation. The electric drill is firmly locked by double-point clamping, which can avoid safety hazards caused by loosening and falling off during operation. A spring buffer structure is set at the bottom, which can effectively reduce drilling vibration and improve operational stability. The frame is equipped with a cable routing structure to organize the cable route and avoid cable tangling and interference with operation. The addition of a rust-proof pad at the bottom can slow down the corrosion of steel in the humid environment.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example: like Figure 1 , Figure 2 As shown, the embedded plate vertical drilling device of this embodiment mainly consists of five parts: a support frame, a lifting transmission mechanism, an electric drill clamping mechanism, a height adjustment mechanism, and a bottom support assembly. Each component is assembled from steel and standard parts commonly used in construction sites. The overall structure is lightweight and easy to transport, and it is suitable for vertical drilling and hole enlargement operations of embedded plates, templates, aluminum alloy profiles and other workpieces on construction sites.

[0022] The support frame serves as the overall load-bearing foundation for the device, including vertical support rectangular tubes 5, diagonal support rectangular tubes 6, stiffening steel plates 15, anti-rust pads 19, fixed round steel bars 20, and cable routing rings 21.

[0023] like Figure 1 As shown, the vertical support rectangular tube 5 serves as the main load-bearing column of the device and is arranged vertically. The inclined support rectangular tube 6 is inclined, with its upper end connected to the lower middle part of the tube wall of the vertical support rectangular tube 5 and its lower end connected to the outer edge of the bottom support component. The connection nodes of the two are reinforced with stiffening steel plates 15 and fastened with matching bolts 17. The vertical support rectangular tube 5, the inclined support rectangular tube 6 and the bottom support component together form a triangular stable support system in the vertical direction, which can effectively improve the overall anti-overturning ability and structural rigidity of the device and prevent the frame from tilting or swaying during drilling operations.

[0024] like Figure 2 As shown, two sets of vertical support rectangular tubes 5 are symmetrically arranged on the left and right sides of the device. Each set of vertical support rectangular tubes 5 is equipped with a set of oblique support rectangular tubes 6, forming a symmetrical and stable load-bearing frame in the plane, ensuring the horizontal force balance of the device.

[0025] like Figure 1 As shown, the bottom end of the vertical support rectangular tube 5 is provided with a rust-proof pad 19. The rust-proof pad 19 is laid flat on the working surface or the bottom bearing structure, which can isolate the column from direct contact with the damp construction surface, slow down the corrosion rate of steel, and extend the service life of the device at the outdoor construction site.

[0026] like Figure 1 and Figure 2As shown, a fixed round steel bar 20 is fixedly connected to the outer wall of the vertical support rectangular tube 5. The fixed round steel bar 20 extends outward in the horizontal direction, and a fixed cable routing ring 21 is welded to its outer end. The cable 22 of the electric drill 23 can pass through the cable routing ring 21 and be tied and fixed. This is used to organize the cable routing during the operation, avoid the cable from getting tangled in the drill rod or transmission components, eliminate the operation hazards caused by cable tangling, and ensure smooth drilling operations.

[0027] The lifting transmission mechanism is the core structure for realizing the vertical feed of the electric drill, including the starting rod 12, the transmission shaft 7, the transmission gear 10, the gear guide rail 13, the transmission chain 14, the rolling sleeve 8, the locking nut 9, and the horizontal guide frame 24.

[0028] like Figure 1 As shown, the gear guide rail 13 is fixedly installed vertically on the inner wall of the vertical support rectangular tube 5, and the transmission chain 14 is welded and fixed to the inner surface of the gear guide rail 13 along its entire vertical length, with the chain teeth facing the inner side of the device; the transmission gear 10 and the transmission chain 14 mesh with each other to form a vertical moving transmission pair.

[0029] A transmission shaft 7 is inserted into the center hole of the transmission gear 10. The transmission shaft 7 is arranged laterally in the horizontal direction. A rolling sleeve 8 is sleeved on its shaft body. Locking nuts 9 are respectively provided on both sides of the rolling sleeve 8. The locking nuts 9 are screwed on the transmission shaft 7 to axially limit the rolling sleeve 8 and the transmission gear 10, ensuring the coaxiality of the transmission shaft 7 during rotation and reducing rotational friction resistance and wear of transmission components.

[0030] The extended end of the transmission shaft 7 is connected to the starting rod 12, which is made of bent round steel 11 with an end forming an operating section for easy gripping by the operator; the inner end of the transmission shaft 7 is rotatably connected to the horizontal guide frame 24. Figure 2 As shown, two sets of gear guide rails and transmission structures are symmetrically arranged on the left and right sides of the horizontal guide 24, so that the horizontal guide 24 is subjected to force on both sides simultaneously, ensuring that it remains horizontal during the lifting process and avoiding skew and jamming caused by force on one side.

[0031] The electric drill clamping mechanism is used to fix the electric drill equipment and ensure the verticality of the drilling. It includes a tail ring cutter adjuster 25 and an end ring cutter adjuster 26, both of which are mounted on the horizontal guide frame 24.

[0032] Combination Figure 1 and Figure 2 As shown, the horizontal guide frame 24 is a frame structure welded from guide frame steel pipe 16, providing a stable installation foundation for the electric drill clamping mechanism and transmission components; the tail ring cutter adjuster 25 and the end ring cutter adjuster 26 are fixed coaxially along the vertical direction inside the frame of the horizontal guide frame 24, and the two are corresponding vertically and coincidentally.

[0033] The tail ring cutter adjuster 25 is located at the upper position, corresponding to the tail section of the drill 23; the end ring cutter adjuster 26 is located at the lower position, corresponding to the drill bit end of the drill 23. Both sets of adjusters are clamp-type adjustable structures. By tightening the matching bolts, the clamping inner diameter can be reduced, firmly locking the drill 23 in a vertical position, allowing the drill 23 to move vertically up and down synchronously with the horizontal guide frame 24; loosening the matching bolts allows the drill 23 to be quickly removed, facilitating equipment maintenance, drill bit replacement, and device transport and storage.

[0034] The body of the electric drill 23 is located at the center of the frame of the horizontal guide 24. The drill rod 27 is installed at its output end. The drill rod 27 rotates synchronously with the electric drill 23 and feeds vertically synchronously with the horizontal guide 24 to complete the drilling operation of the workpiece. By using a two-point coaxial clamping method, the radial wobble during the operation of the electric drill can be effectively constrained, and the drill rod feed direction is structurally guaranteed to be perpendicular to the workpiece surface, thereby improving drilling accuracy.

[0035] The height adjustment mechanism is used to adjust the working height and limit the drilling depth, including the vertical support steel pipe 4 and the steel pipe limit adjuster 18; the bottom support assembly is used for device bearing and buffering shock absorption, including the tray 1, the steel pad 2 and the spring 3.

[0036] The steel pipe limit adjuster 18 is fixed to the lower crossbeam of the support frame. The vertical support steel pipe 4 is vertically inserted into the steel pipe limit adjuster 18, with its upper end corresponding to the lower surface of the horizontal guide frame 24. By adjusting the upward extension length of the vertical support steel pipe 4 and locking the steel pipe limit adjuster 18 to fix its position, the lower limit position of the horizontal guide frame 24 can be limited, thereby limiting the initial working height and the maximum drilling depth. This adapts to workpieces of different thicknesses and avoids excessive feed that could damage the back of the workpiece or cause the drill rod to collide with the bottom structure.

[0037] The tray 1 is laid flat on top of the workpiece to be drilled or on the working surface, serving as the bottom support base of the device, increasing the contact area between the device and the working surface, and reducing local pressure; the steel pad 2 is laid flat on the middle of the upper surface of the tray 1, and the spring 3 is set between the lower end face of the vertical support steel pipe 4 and the upper surface of the steel pad 2; the upper load transmitted by the vertical support steel pipe 4 and the vibration generated by the drilling operation can be buffered and reduced by the elastic deformation of the spring 3, improving the stability of the device operation, while avoiding impact damage caused by direct contact of rigid components.

[0038] The planar dimensions of the pallet 1 are larger than the projected dimensions of the main body of the device. The steel pad 2 is centrally located on the pallet 1, and the vertical support steel pipe 4 is correspondingly located in the central area of ​​the steel pad to ensure that the vertical force is evenly transmitted and to avoid the device tilting due to uneven loading.

[0039] The device is easy to assemble, and all components can be processed and manufactured on-site without the need for large processing equipment. The device is lightweight and compact, and can be moved by a single person, making it flexible to meet the scattered drilling needs of different work positions on the construction site.

[0040] Working principle: First, place the device above the embedded plate to be drilled, and adjust the device position so that the drill rod 27 is aligned with the drilling point. Based on the workpiece thickness and drilling depth, adjust the height of the vertical support steel pipe 4 using the steel pipe limit adjuster 18 to determine the initial position of the horizontal guide frame 24. Insert the electric drill 23 into the two sets of ring cutter adjusters, tighten the adjusters to fix the electric drill, and comb and fix the cable 22 at the cable routing ring 21. After starting the electric drill 23, manually rotate the starting rod 12 at a uniform speed. Through the transmission gear 10 and transmission chain 14, the horizontal guide frame 24 is driven vertically downwards, and the drill rod 27 contacts the workpiece to complete the drilling operation. After drilling is completed, rotate the starting rod 12 in the opposite direction to raise and reset the electric drill 23. Release the ring cutter adjuster to remove the electric drill or move the device to the next drilling location. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
