Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ventilation duct installation technology, and in particular relates to a ventilation duct installation angle steel hole-opening device. Background Technology
[0002] Ventilation ducts are metal or composite pipes used in ventilation and air conditioning projects in industrial and civil buildings. They are a type of municipal infrastructure designed to circulate air and reduce the concentration of harmful gases. In large supermarkets, shopping malls, and other public places, central air conditioning is usually installed. The cold air from the central air conditioning system is typically delivered to various locations through a dense network of ventilation ducts. Angle steel mounting brackets are used when hoisting and fixing the ventilation ducts.
[0003] Angle steel mounting brackets are typically fabricated on-site through a process of cutting, drilling, and welding angle steel. Drilling angle steel requires a drilling machine, which needs to remain stable during drilling to prevent the angle steel from rotating due to the rotational force of the drill. Therefore, a ventilation duct mounting bracket for angle steel is needed. By applying clamping and fixing force to the angle steel, its position is stabilized when subjected to drilling force, thus ensuring the safety and efficiency of the drilling operation. Utility Model Content
[0004] The purpose of this utility model is to provide a device for drilling holes in angle steel for ventilation ducts, which applies a clamping and fixing force to the angle steel so that its position is stable when subjected to drilling force, thereby ensuring the safety and efficiency of drilling operations, and solving the technical problems mentioned in the background art.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A ventilation duct installation angle steel hole-opening device, which includes a processing table: a hole-opening component is installed on the top of the processing table, an angle steel is provided on the top of the processing table, a horizontal plate is fixedly connected to the right side of the processing table by bolts, a base plate is fixedly connected to the bottom of the horizontal plate by bolts, a cylinder and two symmetrically arranged slide rails are fixedly installed on the bottom of the base plate by bolts, a slider is slidably connected to the surface of the slide rails, a push-pull plate is fixedly connected to the output end of the cylinder by a flange, a dial shaft is integrally formed on the surface of the slider, a U-shaped rod is welded to the surface of the slider, and a slot plate and a clamping plate are respectively welded to the ends of the two U-shaped rods.
[0006] Preferably, the bottom end of the dial shaft extends into the inner cavity of the push-pull plate, and a rotating sleeve is rotatably connected to the surface of the dial shaft, with the surface of the rotating sleeve fitting against the inner wall of the push-pull plate.
[0007] Preferably, the bottom of the base plate is fixedly connected to two symmetrically arranged clamping blocks by bolts, and the inner wall of the clamping blocks is slidably connected to the push-pull plate.
[0008] Preferably, a limiting sleeve is welded to the top of the horizontal plate, and a sliding rod is slidably connected to the inner wall of the limiting sleeve. The slot plate and the locking plate are both fixedly connected to the end of the sliding rod.

The two U-shaped rods then move a slot plate and a clamping plate, respectively, so that the slot plate and the clamping plate clamp and limit the angle steel. This achieves the purpose of applying clamping and fixing force to the angle steel, so that its position is stable when subjected to drilling force, thereby ensuring the safety of drilling operations and the efficiency of hole opening.
[0012] 2. By setting up a rotating sleeve, this utility model provides padding protection between the dial shaft and the push-pull plate, avoiding excessive wear when the two are in direct contact, thereby extending their service life.
[0013] 3. By setting the clamping block, this utility model limits the movement of the push-pull plate, avoiding the wobbling of the push-pull plate during movement, thereby improving the stability of the push-pull plate when it moves.
[0014] 4. This utility model uses the combination of the limiting sleeve and the sliding rod to limit the movement of the slot plate and the clamping plate, thereby improving the stability of the slot plate and the clamping plate in clamping and fixing the angle steel. Attached Figure Description

The surface of the slider 8 is in contact with the inner wall of the push-pull plate 9. The rotating sleeve 11 is used to protect the push-pull plate 9 from direct contact, thus avoiding excessive wear and extending the service life of both. The surface of the slider 8 is welded with a U-shaped rod 12. The bottom of the base plate 5 is fixedly connected with two symmetrically arranged clamping blocks 13 by bolts. The inner wall of the clamping block 13 is slidably connected to the push-pull plate 9. The clamping block 13 limits the movement of the push-pull plate 9, preventing the push-pull plate 9 from shaking during movement and improving the stability of the push-pull plate 9 during movement. The ends of the two U-shaped rods 12 are respectively welded with a slot plate 16 and a clamping plate 17.
[0025] Example 2:
[0026] Figure 1-4This invention illustrates a ventilation duct installation angle steel opening device according to an embodiment of the present invention. It includes a processing table 1; an opening assembly 2 is installed on the top of the processing table 1; an angle steel 3 is provided on the top of the processing table 1; a horizontal plate 4 is bolted to the right side of the processing table 1; a base plate 5 is bolted to the bottom of the horizontal plate 4; a cylinder 6 and two symmetrically arranged slide rails 7 are bolted to the bottom of the base plate 5; sliders 8 are slidably connected to the surface of the slide rails 7; a push-pull plate 9 is fixedly connected to the output end of the cylinder 6 via a flange; and a pivot shaft 1 is integrally formed on the surface of the slider 8. 0. A U-shaped rod 12 is welded to the surface of the slider 8. The ends of the two U-shaped rods 12 are respectively welded to the slot plate 16 and the clamping plate 17. A limit sleeve 14 is welded to the top of the horizontal plate 4. A slide rod 15 is slidably connected to the inner wall of the limit sleeve 14. The slot plate 16 and the clamping plate 17 are fixedly connected to the ends of the slide rod 15. The slot plate 16 and the clamping plate 17 are in contact with the angle steel 3. Through the cooperation of the limit sleeve 14 and the slide rod 15, the movement of the slot plate 16 and the clamping plate 17 is limited, which improves the stability of the slot plate 16 and the clamping plate 17 in clamping and fixing the angle steel 3.
[0027] Working principle: When using this utility model, the user places the angle steel 3 on the top of the processing table 1, then activates the cylinder 6 to move the push-pull plate 9, which in turn moves the two pivot shafts 10. The pivot shafts 10 then move the U-shaped rod 12 via the slider 8. During this process, the slide rail 7 limits the movement of the slider 8, ensuring its stability. Then, the two U-shaped rods 12 move the slot plate 16 and the clamping plate 17 respectively, clamping and limiting the angle steel 3. Then, the drilling assembly 2 is activated to drill the angle steel 3, thus applying a clamping and fixing force to the angle steel, stabilizing its position when subjected to drilling force, thereby ensuring the safety and efficiency of the drilling operation.
[0028] In summary: This ventilation duct installation angle steel hole-opening device moves two pivot shafts 10 by pushing and pulling plate 9, causing the pivot shafts 10 to move U-shaped rods 12 via slider 8. Subsequently, the two U-shaped rods 12 move the slot plate 16 and the clamping plate 17 respectively, so that the slot plate 16 and the clamping plate 17 clamp and limit the angle steel 3, thereby applying a clamping and fixing force to the angle steel, so that its position is stable when subjected to drilling force, thus ensuring the safety of drilling operations and the efficiency of hole opening.
