Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, specifically a positioning device for steel structure engineering construction. Background Technology

[0002] Steel structure engineering is an engineering system that uses steel as the main load-bearing material and constructs buildings or facilities through connection, processing and installation processes. Its core lies in utilizing the high strength, lightweight and plasticity of steel to achieve rapid construction of large-span, high-rise and complex structures.

[0003] Steel structures are composed of basic components such as structural steel, steel plates, and steel pipes, which are welded, bolted, or riveted to form spatial structures such as frames, space frames, and trusses. This necessitates manual welding and other processes for connecting and fixing steel structures. However, during steel structure construction, workers often need to move their upper bodies left and right to perform welding and other procedures. The lack of proper positioning for the workers' upper bodies during this process raises concerns about safety when working at heights. Therefore, we provide a positioning device for steel structure construction to address these issues. Utility Model Content

[0005] The purpose of this invention is to address the lack of positioning for the upper body of construction workers in existing systems, which leads to a need to improve the safety of construction workers working at heights. This invention provides a positioning device for steel structure engineering construction.

[0006] (ii) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for steel structure engineering construction, comprising a grooved plate, wherein two symmetrical straight rods are hinged to the inner wall of the grooved plate, and a U-shaped clamping plate is hinged to the far end of each of the two straight rods, and a sliding groove is provided on the bottom surface of each of the two straight rods; two symmetrical piston rods are slidably connected to the inner wall of a piston cylinder provided at the lower part of the grooved plate; sliders hinged to the far ends of the two piston rods are slidably connected to the inner wall of a sliding groove respectively; a rope is fixedly connected to the outer surface of the piston cylinder, and a carrying strap is fixedly connected to the lower end of the rope; a pair of limiting straps are fixedly connected to the outer surface of the carrying strap.

[0008] Furthermore, the air bladder disposed outside the piston cylinder is connected to the interior of the piston cylinder through a first one-way valve, and a second one-way valve is fixedly connected to the outer surface of the air bladder.

[0009] Furthermore, the vent pipe fixedly connected to the outlet of the first one-way valve is connected to the interior of the piston cylinder, and the inlet of the first one-way valve and the outlet of the second one-way valve are both connected to the interior of the air bladder, while the inlet of the second one-way valve is connected to the outside.

[0010] Furthermore, the inner wall of the piston cylinder is fixedly connected with two symmetrical limiting rings, and the upper part of the outer surface of the piston cylinder is threaded with a threaded rubber plug. The lower end of the threaded rubber plug extends into the interior of the piston cylinder, and the lower end of the threaded rubber plug and the connection between the vent pipe and the piston cylinder are both located between the two limiting rings.

[0011] Furthermore, a rubber layer is fixedly connected to the opposite side of each of the pair of U-shaped plates, and rubber particles are fixedly connected to the outer surface of each of the two rubber layers.

[0012] Furthermore, a grip is fixedly connected to the outer surface of the straight rod, and a pair of handles are rotatably connected to the lower part of the outer surface of the piston cylinder.

[0014] (iii) Beneficial effects:

[0015] Compared with existing technologies, this positioning device for steel structure construction has the following advantages:

[0016] This invention allows the device to be positioned between two steel structures by gripping the handles with both hands. By moving the two straight rods inward or outward, the angle between them is changed. The rubber layer and rubber granules fixed to the outer surface of the two U-shaped clamping plates come into contact with the steel structures on both sides. During this process, the piston rod moves outward on the inner wall of the piston cylinder. Then, pulling the rope downward several times makes the device more tightly engaged with the steel structures on both sides. By rotating the limiting bolt, the limiting bolt passes through the piston cylinder and engages with the outer surface of the piston rod, limiting the piston rod on the inner wall of the piston cylinder. This makes the triangular structure of the device more robust, and the device can be easily engaged with steel structures at different intervals. It also provides auxiliary restraint for the user's upper body, improving the user's safety when working at height. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-4 As shown, this utility model provides a technical solution: a positioning device for steel structure engineering construction, including a grooved plate 1, with two symmetrical straight rods 2 hinged to the inner wall of the grooved plate 1. A handle 19 is fixedly connected to the outer surface of the straight rods 2. The handle 19 facilitates initial position adjustment of the device, allowing the U-shaped clamping plates 3 on both sides to better engage with the steel structure on both sides. A U-shaped clamping plate 3 is hinged to the opposite end of each of the two straight rods 2, and a sliding groove 9 is provided on the bottom surface of each of the two straight rods 2. A rubber layer 17 is fixedly connected to the opposite side of each pair of U-shaped clamping plates 3, and rubber granules 18 are fixedly connected to the outer surface of each of the two rubber layers 17. The combination of the rubber layers 17 and the rubber granules 18 increases the friction on the outer surface of the U-shaped clamping plates 3, allowing the device to better engage with the steel structure on both sides.

[0024] Two symmetrical piston rods 5 are slidably connected to the inner wall of the piston cylinder 4 located at the lower part of the groove plate 1. A pair of handles 20 are rotatably connected to the lower part of the outer surface of the piston cylinder 4. The handles 20 are designed for easy gripping by the user. A pair of limiting bolts 23 are threadedly connected to the outer surface of the piston cylinder 4. By rotating the limiting bolts 23, the limiting bolts 23 can extend into the piston cylinder 4 and engage with the outer surface of the piston rods 5 to limit the two piston rods 5. The sliders 10, which are hinged to the far ends of the two piston rods 5, are slidably connected to the inner wall of a groove 9. A rope 6 is fixedly connected to the surface, and a shoulder strap 7 is fixedly connected to the lower end of the rope 6. Adjustable buckles 21 are provided on the outer surfaces of both the rope 6 and the shoulder strap 7. The length of the rope 6 and the tightness of the shoulder strap 7 can be adjusted by adjusting the buckles 21 so that the shoulder strap 7 fits the user's body shape. The user's arm passes through the shoulder strap 7 and the limiting strap 8, and the shoulder strap 7 is locked to the user's upper body. Two interlocking buckles 22 are fixedly connected to the lower part of the outer surface of the shoulder strap 7. A pair of limiting straps 8 are fixedly connected to the outer surface of the shoulder strap 7, and the two ends of the limiting straps 8 are fixedly connected to the two sides of the outer surface of the shoulder strap 7.

[0025] The user's arm passes between the back strap 7 and the limiting strap 8. The rope 6 is adjusted to a suitable length using the adjusting buckle 21, and the back strap 7 is adjusted to fit the user's body shape and engage. The user grips the handle 19 with both hands, positioning the device between the steel structures on both sides. By pulling the two straight rods 2 inward or outward using the handle 19, the angle between the two straight rods 2 is changed. The rubber layer 17 and rubber granules 18, which are fixedly connected to the outer surfaces of the two U-shaped clamping plates 3, come into contact with the steel structures on both sides. During this process, the piston rod 5 moves left and right on the inner wall of the piston cylinder 4. Then, the rope 6 is pulled downward several times to make the device engage more tightly with the steel structures on both sides. By rotating the limiting bolt 23, the limiting bolt 23 passes through the piston cylinder 4 and engages with the outer surface of the piston rod 5, limiting the piston rod 5 on the inner wall of the piston cylinder 4. This makes the triangular structure of the device more robust, and the device can easily engage with steel structures at different intervals. It also provides auxiliary restraint for the user's upper body, improving the user's safety when working at height.

[0026] An air bladder 11 externally mounted on the piston cylinder 4 is connected to the interior of the piston cylinder 4 via a first one-way valve 12. A second one-way valve 13 is fixedly connected to the outer surface of the air bladder 11. The outlet end of the first one-way valve 12 is fixedly connected to a vent pipe 14, which is connected to the interior of the piston cylinder 4. Both the inlet end of the first one-way valve 12 and the outlet end of the second one-way valve 13 are connected to the interior of the air bladder 11. The inlet end of the second one-way valve 13 is connected to the outside. The coordinated arrangement of the second one-way valve 13 and the vent pipe 14 ensures the airflow direction inside the air bladder 11. That is, by continuously pressing the air bladder 11, external air flows through the second one-way valve 13, the air bladder 11, the first one-way valve 12, and the vent pipe 14 to the piston cylinder 4. The internal air pressure of the piston cylinder 4 is increased, which makes the initial adjustment at both ends of the device more tightly connected to the steel structure on both sides. Two symmetrical limiting rings 15 are fixedly connected to the inner wall of the piston cylinder 4. The limiting rings 15 limit the movement of the two piston rods 5 on the inner wall of the piston cylinder 4. A threaded rubber plug 16 is threadedly connected to the upper part of the outer surface of the piston cylinder 4. The lower end of the threaded rubber plug 16 extends into the interior of the piston cylinder 4, and the lower end of the threaded rubber plug 16 and the connection between the vent pipe 14 and the piston cylinder 4 are both located between the two limiting rings 15. The threaded rubber plug 16 can be disengaged from the outer surface of the piston cylinder 4 by rotation, and the air inside the piston cylinder 4 can flow to the outside to depressurize and reset the piston cylinder 4.

[0027] Working principle: The user's arm passes between the back strap 7 and the limiting strap 8. The rope 6 is adjusted to a suitable length using the adjusting buckle 21, and the back strap 7 is adjusted to fit the user's body shape and engage. The user grips the handle 19 to bring the device between the steel structures on both sides. By pulling the handle 19 inward or outward, the two straight rods 2 are changed, altering the angle between them. The rubber layer 17 and rubber granules 18, which are fixedly connected to the outer surfaces of the two U-shaped clamping plates 3, come into contact with the steel structures on both sides. During this process, the piston rod 5 moves outward on the inner wall of the piston cylinder 4. Then, the rope 6 is pulled downward several times to make the device more tightly engaged with the steel structures on both sides. By rotating the limiting bolt 23, the limiting bolt 23 passes through the piston cylinder 4 and engages with the outer surface of the piston rod 5, limiting the piston rod 5 on the inner wall of the piston cylinder 4. This makes the triangular structure of the device more robust, allowing the device to easily engage with steel structures at different intervals. It also provides auxiliary restraint for the user's upper body, improving the user's safety when working at height.
