Description

Technical Field

[0001] The invention relates to the technical field of wooden structures for construction, in particular to a magnetically controlled high-stability long hole drill for use in the production of assembled wooden structures. Background Art

[0002] Prefabricated timber structures are one of the primary materials used in wooden buildings. Prefabricated timber structures are characterized by prefabricating the primary load-bearing components, assemblies, and parts in a factory and then installing them on-site. Prefabricated timber structures are designed to be sustainable throughout their lifecycle. Prefabricated timber structures can be categorized as lightweight timber, glulam, log, and hybrid timber, depending on the materials used for their load-bearing components.

[0003] Prefabricated wood structures have a superior environmental impact compared to traditional construction at every stage of a building's lifecycle. This is demonstrated by the following: Less water pollution: Wood is a natural material, and processing and sawing logs into lumber consumes very little water, resulting in minimal impact on water quality; Low energy consumption leads to minimal greenhouse effect: Low energy consumption during extraction, production, construction, and transportation minimizes the greenhouse effect of wooden structures; Solid waste is more environmentally friendly: Wood production waste can be repurposed to produce particleboard, wood pellet fuel, and activated carbon, and is 100% biodegradable; Air purification: Trees absorb CO2 and release oxygen as they grow, purifying the air; Lighter wood structures weigh only 12%-20% of concrete structures. During an earthquake, lighter structures experience less seismic force and less swaying inertia.

[0004] During the processing and production of prefabricated wooden structures, holes need to be punched inside the wooden structure to facilitate subsequent assembly. Traditional punching methods can only be used for short-distance punching. When punching over long distances, the distance between the punching head and the connection end is long, and the punching stability is very limited, which can easily affect the punching accuracy. In addition, the control is also inconvenient, and the processing efficiency is relatively low. Summary of the Invention

[0026] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0027] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0028] Figure 1 、 Figure 2 and Figure 3The assembled wood structure production shown in the figure uses a magnetically controlled high-stability long hole drill, which includes a main frame 1, a tilting conveying platform installed on the main frame 1, an electric-controlled hydraulic support rod 2 for controlling the tilting conveying platform, a long hole drill bit 3, an electric-controlled punch body 4 for controlling the operation of the long hole drill bit 3, an overhead lifting motor 5 for controlling the lifting of the electric-controlled punch body 4, a magnetic induction switch 6, an adjusting motor 7 and an electromagnet 8 controlled by the adjusting motor 7 for synchronous lifting. The main frame 1 is provided with an internal tilting chamber 9 for assembling the tilting conveying platform and the electric-controlled hydraulic support rod 2. A top mounting frame 10 for mounting the electric-controlled punch body 4 and the overhead lifting motor 5 is bolted to the upper end. The upper end of the long-hole drill bit 3 is coaxially fixed to the drive shaft at the lower end of the electric-controlled punch body 4. The coaxial assembly end of the long-hole drill bit 3 is sleeved and fixed with an external stabilizing sleeve 12 with a built-in permanent magnet 11. A bottom guide frame 13 is fixedly assembled inside the internal turnover chamber 9 and the turnover conveying platform. An assembly screw 14 controlled by the adjustment motor 7 is movably assembled inside the bottom guide frame 13. An internally threaded guide block 15 for mounting the electromagnet 8 is threadedly sleeved on the outer side of the assembly screw 14.

[0029] The electric-controlled hydraulic support rod 2, the long hole drill bit 3, the electric-controlled punch body 4, the overhead lifting motor 5, the magnetic induction switch 6, the adjustment motor 7 and the electromagnet 8 are all existing technologies, which are purchased through the market. They are powered by an external power supply and controlled by the external electric control system of the existing technology.

[0030] Working principle: The assembled wooden structure board is transported forward by the flip conveying platform. When it is transported to the punching position, the electric-controlled hydraulic support rod 2 is started, and the electric-controlled hydraulic support rod 2 drives the flip conveying platform to flip upward. After the flip conveying platform flips 90°, the overhead lifting motor 5 starts to start, driving the electric-controlled punch body 4 to descend, and the long hole drill bit 3 drives the external stabilizing sleeve 12 with the built-in permanent magnet 11 to move downward synchronously. When the magnetic induction switch 6 senses the magnetic field of the permanent magnet 11, it controls the electric-controlled punch body 4, the adjustment motor 7 and the electromagnet 8 to start. At this time, the electric-controlled punch body 4 controls the long hole drill bit 3 to drill holes in the board. At the same time, the adjustment motor 7 drives the internal thread guide block 15 with the electromagnet 8 on the side to move downward synchronously with the external stabilizing sleeve 12 to maintain the punching stability of the long hole drill bit 3.

[0031] In order to cooperate with the flip adjustment, the bottom surface of the internal flip chamber 9 is provided with an upwardly protruding bottom movable assembly frame 16, and the flip conveying platform includes a flip frame 17 movably connected to the bottom movable assembly frame 16 on both sides, a lateral limit frame 18 fixed on the upper surface of the connection end of the flip frame 17, a main support roller 19 movably assembled inside the flip frame 17 and a side support roller 20 movably assembled inside the lateral limit frame 18, the lower end of the flip frame 17 is provided with a bottom mounting frame 21, and the top of the telescopic section of the electric-controlled hydraulic strut 2 is inserted into the bottom mounting frame 21 through a coaxially fixed movable connecting head and is movably connected to the flip frame 17.

[0032] In order to cooperate with the bottom transmission control, a bottom transmission chamber 22 for installing the adjustment motor 7 is opened on the inner bottom surface of the internal flip chamber 9. A lateral control shaft 23 is coaxially fixed on the adjustment shaft on both sides of the adjustment motor 7, and a lateral bevel gear 24 is coaxially sleeved on the lateral control shaft 23.

[0033] An upper protective cover is installed at the upper opening of the bottom transmission chamber 22 .

[0034] In order to cooperate with the bottom meshing transmission, a bottom transmission gear 25 meshing with the lateral bevel gear 24 is coaxially fixed to the lower end of the assembly screw rod 14 .

[0035] The assembly screw 14 of the bottom guide frame 13 on the inner wall of the internal flip chamber 9 maintains a transmission state with the adjustment motor 7, and the assembly screw 14 of the bottom guide frame 13 inside the flip conveying platform engages and transmits with the lateral bevel gear 24 on the adjustment motor 7 only when the flip conveying platform is flipped upward.

[0036] In order to cooperate with the top lifting, side guide grooves 26 are opened on the inner walls on both sides of the top mounting frame 10. The top side lifting screw 27 controlled by the top lifting motor 5 is movably assembled inside the side guide groove 26. The lower end of the outer side of the electric-controlled hole punch body 4 is fixedly assembled with a lifting control seat 28 that cooperates with the top side lifting screw 27. The lifting control seat 28 is threadedly assembled with the top side lifting screw 27 through the internal threaded lifting cylinder 29 of the integrated structure on both sides.

[0037] A lateral transmission groove 30 is provided on the side wall of the internal thread guide block 15 , and an internal guide frame 32 for assembling a lateral transmission roller 31 and the electromagnet 8 is elastically assembled inside the lateral transmission groove 29 .

[0038] In order to facilitate assembly, a top corner transmission groove for installing the lateral transmission roller 31 is opened at the top corner position of the outer side of the internal guide frame 32, and the electromagnet 8 is fixedly installed inside the internal guide frame 32 by bolts.

[0039] The distance between the electromagnet 8 and the surface of the wooden structure can be adjusted by bolts. The adjustment mechanism consists of an adjusting bolt and four assembly bolts. The installation position of the electromagnet 8 and the internal guide frame 32 can be changed by changing the assembly position of the adjusting bolt and the assembly bolt.

[0040] In order to facilitate loading and unloading, the long hole drill bit 3 includes a bottom drill bit section 33 and a top drive section 34 coaxially fixed with the lower end rotating shaft of the electric-controlled punch body 4. The external stabilization sleeve includes a central adsorption section 35 with an internal fixed permanent magnet 11, an externally threaded notch tightening section 36 coaxially fixed at both ends of the central adsorption section 35, and a locking nut 37 threadedly sleeved on the outside of the externally threaded notch tightening section 36.

[0041] The outer diameter of the long hole drill bit 3 is larger than the outer diameter of the locking nut 37. The outer diameter of the assembly end of the long hole drill bit 3 and the top drive section 34 is smaller than the outer diameter of the external thread shrinking and tightening section 36, and is located between the minimum and maximum inner diameters of the external thread shrinking and tightening section 36.

[0042] In order to cooperate with the automatic magnetic induction control, a lateral monitoring groove for installing the magnetic induction switch 6 is opened on the outer surface of the internal thread guide block 15. The control end of the magnetic induction switch 6 is electrically connected to the control end of the electromagnet 8 through the control circuit located inside the internal thread guide block 15.

[0043] When the long hole drill bit 3 descends, the external stabilizing sleeve with the built-in permanent magnet 11 is driven to descend. When the external stabilizing sleeve descends to the position of the magnetic induction switch 6, the magnetic induction switch 6 detects the magnetic field and controls the electromagnet 8 at the corresponding position to start. When the electromagnet 8 is started, the regulating motor 7 is controlled to start, driving the electromagnet 8 to descend at the same speed as the external stabilizing sleeve, and keeping synchronous descent. At the same time, the electromagnet 8 magnetically adsorbs the external stabilizing sleeve from both sides, which can maintain the stability of the entire long hole drill bit 3.

[0044] In order to improve lateral support and stability, side auxiliary guide wheels 38 are movably mounted on the longitudinal side walls of the internal turning chamber 9 .

[0045] The magnetically controlled high-stability long-hole drill for prefabricated wood structures of the present invention adopts an internal reversing chamber 9 provided inside a main frame 1. The angle of the reversing conveying platform is adjusted by an electrically controlled hydraulic support rod 2 inside the internal reversing chamber 9, thereby facilitating the angle adjustment of the plate. The prefabricated wood structure is operated in a longitudinal drilling manner, thereby improving stability, reducing the lateral space occupied, and reducing the equipment footprint. The reversing conveying platform drives the bottom guide frame 13 to rotate synchronously at the same time. After the reversal of the bottom guide frame 13 is completed, the assembly state of the motor 7 and the assembly screw 14 is automatically controlled and adjusted. The stability and synchronization of the lifting of both sides are maintained by a synchronous transmission lifting method on both sides. The electromagnet 8 inside the internal threaded guide block 15 magnetically attracts the external stabilizing sleeve of the connecting end of the long-hole drill bit 3. The multi-directional magnetic attraction method is used to maintain the stability of its drilling end, while also maintaining the lateral support force and stability of the prefabricated wood structure, greatly improving the accuracy of drilling. The magnetic induction switch 6 senses the permanent magnet 11 to automatically control the electromagnet 8, making operation simpler and more convenient, and energy consumption control more efficient.

[0046] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention.
