Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for building construction, and specifically to a large-scale galvanized square steel drilling device. Background Technology

[0002] In the construction of large steel structures, it is often necessary to drill holes in a large number of galvanized square steel bars. The traditional method relies on manual hand-held electric drills to locate and drill holes one by one, which has the following obvious drawbacks: 1) low positioning efficiency and high repetitive labor intensity; 2) difficulty in ensuring the verticality of the drill holes, affecting the installation accuracy; 3) long hours of holding the electric drill, resulting in high physical exertion for workers, affecting construction efficiency and safety.

[0003] While some drilling fixtures exist in the existing technology, most are complex in structure, rely on external power, or are not optimized for batch, high-precision drilling operations. Therefore, there is an urgent need for a dedicated device that is simple in structure, consumes no energy, provides precise positioning, and can significantly reduce labor intensity. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a large-scale galvanized square steel drilling device that is simple in structure, energy-free, accurately positioned, and can significantly reduce labor intensity.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A large-scale galvanized square steel drilling device includes: a base for supporting the galvanized square steel to be drilled; vertical support columns fixedly connected to both sides of the base; a guide beam horizontally fixedly connected to the top of the vertical support columns; a guide sleeve slidably fitted onto the guide beam; and a mounting part disposed at the lower part of the guide sleeve for fixing an electric drill.

[0006] Furthermore, the mounting section is provided with a hanging structure for fixing the electric drill in a suspended manner.

[0007] Furthermore, the upper surface of the base is provided with multiple Z-shaped baffles for laterally limiting the galvanized square steel.

[0008] Furthermore, the mounting section consists of two nested steel pipes of different diameters.

[0009] Furthermore, the vertical support column is an L-shaped angle steel.

[0010] Furthermore, the base, vertical support column, guide beam, and guide sleeve are all constructed from welded metal profiles to form a purely mechanical structure.

[0011] Furthermore, the base is equipped with support legs evenly distributed at its bottom. Beneficial effects

[0012] Zero energy consumption: Completely independent of traditional energy sources such as electricity and fuel oil, it reduces carbon emissions at the source, aligning with green construction requirements. Simultaneously, it eliminates energy procurement and equipment purchase and maintenance costs, avoids energy-related safety hazards, and lowers overall costs and risks.

[0013] Easy to make: The raw materials are common market items, making procurement convenient. The production process is simple, requiring no complex techniques or specialized equipment; ordinary construction workers can operate it after simple training.

[0014] High efficiency: When dealing with a large number of galvanized square steel bars with identical hole positions, the pre-set hole positions on the base can effectively reduce the time required for positioning during drilling and improve drilling efficiency.

[0015] It works well. In long-term, large-scale drilling operations, this device can effectively reduce the physical exertion required for workers to lift the electric drill, ensuring the verticality and accuracy of the hole position, and its effect is obvious. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The specific dimensions described in this embodiment are merely a preferred method for implementing the technical solution of the present invention and are not intended to limit the present invention.

[0020] like Figure 1 As shown in the figure, the specific structure and dimensions of the large-scale galvanized square steel drilling device provided in this embodiment are as follows: Base (1): The overall length is approximately 6000mm to accommodate galvanized square steel of common lengths. The main body of base 1 is made of galvanized square steel with a cross-sectional dimension of 200mm (width) × 200mm (height). To enhance stability, six support legs 7 are welded along the length of the main body of base. Each support leg 7 is made of galvanized square steel with a cross-sectional dimension of 100mm × 100mm and a height of approximately 100mm, arranged in pairs. On the upper surface of the main body of base 1, multiple Z-shaped baffles 6 are welded at intervals along its length to provide lateral positioning and limitation for the galvanized square steel placed on it. The vertical plate height of the Z-shaped baffle 6 is approximately 60mm, the horizontal folded edge length is approximately 100mm, and the spacing between adjacent baffles can be flexibly set according to the commonly used square steel length, for example, approximately 1400mm or 1450mm.

[0021] Vertical support column 2: Four equilateral L-shaped angle steels, each 200mm x 200mm, are used, with a vertical height of approximately 1500mm. The four angle steels are arranged in pairs and vertically welded to both sides of the base 1 along its length to provide support for the upper structure.

[0022] Guide beam 3: It is made of galvanized square steel with a cross-section of 200mm×200mm and a length of approximately 6000mm, and its length direction is consistent with that of the base 1. The guide beam 3 is horizontally welded to the top of the vertical support columns 2 on both sides, forming a sturdy horizontal track located directly above the base.

[0023] Guide sleeve 4 and electric drill mounting part: The lower part of the guide sleeve 4 is provided with a mounting part 5 for fixing the electric drill. In this embodiment, it is made of a DN50 steel pipe with a length of 300mm and a DN65 steel pipe with a length of 100mm, which are coaxially nested and welded together to form a mechanism that can be slidably sleeved on the guide beam 3. Below the guide sleeve 4, a mounting part is fixedly connected. The mounting part includes two vertically downward DN50 steel pipes with a length of about 200mm as hanging arms. The bottom end of the hanging arms is provided with through holes or hooks for threading steel wire ropes or straps, so as to securely fix the electric drill in a suspended manner.

[0024] Working principle and usage: The core working principle of this device is to use a purely mechanical structure to provide a stable and movable vertical drilling guide rail for the electric drill through the guide beam (3) and guide sleeve (4), while using the Z-shaped baffle (6) on the base (1) to quickly position the workpiece, thereby realizing batch, high efficiency and high precision drilling operations.

[0025] The specific operating steps are as follows: Workpiece placement: Place the galvanized square steel to be drilled horizontally on the base 1, so that one side of it is in close contact with the multiple Z-shaped baffles 6 welded to the upper surface of the base, so as to achieve rapid positioning and limiting of the workpiece in the width direction.

[0026] Fixed Electric Drill: The handheld electric drill is suspended and fixed to the hanging structure of the mounting part 5 using tools such as straps and ropes. The height of the drill bit can be initially adjusted by adjusting the hanging length or by utilizing the nested steel pipe structure of the mounting part 5.

[0027] Positioning the hole: Slide the guide sleeve 4 horizontally along the guide beam 3 to move the drill bit to the preset position on the galvanized square steel where the hole needs to be drilled. For batch drilling, length-direction graduation marks can be made on the base or workpiece to achieve quick and accurate hole positioning.

[0028] Drilling: The operator only needs to apply appropriate downward pressure, and the electric drill will move steadily downward under the vertical constraint of the guide sleeve 4 to drill. During drilling, the sliding of the guide sleeve along the crossbeam is restricted, ensuring the verticality of the drill hole. After drilling is completed, the pressure is released, and the electric drill returns to its original position under the suspension.

[0029] Move to the next hole: Slide the guide sleeve 4 horizontally to the next drilling position, and repeat step 4 to efficiently complete the work on multiple holes on the same workpiece. When changing to the next galvanized square steel, repeat steps 1-4.
