Description

Technical Field

[0001] This utility model relates to the field of vertical shaft pipeline installation technology, specifically a pipeline installation mechanism inside a vertical shaft. Background Technology

[0002] In the installation process of public high-rise buildings, large HVAC systems are usually installed. Due to factors such as the building's floor height, limited space in the pipe shaft, and the length and weight of the large pipes, the traditional construction method involves cutting the air conditioning water risers into lengths of about 4 meters and transporting them one by one to each floor, then installing them from the first floor upwards in a direct installation manner.

[0003] Currently, the installation of air conditioning risers in vertical shafts still requires manual operation. The specific process involves first installing a winch at the top of the shaft, welding hooks to the outer wall of the riser, and then gradually lifting the riser upwards using the winch until the riser is connected to the main pipe. After the connection is complete, workers then weld the two pipes together. However, during the hoisting process, the riser inevitably experiences slight swaying, causing it to shift from the main pipe to the central axis, making it impossible to align the central axis. This necessitates manual intervention at the connection point. This correction method is not only inefficient but also inherently dangerous, slowing down the installation of air conditioning water main pipes in high-rise building shafts and increasing the labor intensity of manual operations.

[0004] Therefore, this utility model proposes a pipe installation mechanism inside a vertical shaft. Utility Model Content

[0005] The purpose of this utility model is to provide a pipe installation mechanism in a vertical shaft to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a pipe installation mechanism in a vertical shaft, including a riser, with a clamping sleeve one and a clamping sleeve two on the outer wall of the riser, the clamping sleeve one and the clamping sleeve two being hinged to each other, and a hanging seat on the outer wall of both the clamping sleeve one and the clamping sleeve two, with an abutment plate one above the clamping sleeve one and an abutment plate two above the clamping sleeve two, the overall shape of the abutment plate one and the abutment plate two being an outwardly expanding arc surface.

[0006] Preferably, both clamping sleeve one and clamping sleeve two have grooves on their walls. When clamping sleeve one and clamping sleeve two are combined, the ends of the two grooves are connected to each other, and the end of the riser is located in the central area of ​​the groove.

[0007] Preferably, the outer walls of both clamping sleeve one and clamping sleeve two are provided with multiple folding plates. The folding plates are L-shaped, with a fixed shaft inside and a fixed block outside the fixed shaft.

[0008] Preferably, a torsion spring is provided between the fixed block and the fixed shaft, and under normal conditions, the spring force of the torsion spring causes the rotating folding plate to be perpendicular to the central axis of the riser.

[0009] Preferably, the upper part of the folding plate is provided with multiple equidistant ridges, and the bottom end of the main pipe contacts the surface of the ridges during the rising process of the riser.

[0010] Preferably, clamping sleeve one and clamping sleeve two are connected by bolts.

[0011] This utility model has at least the following beneficial effects:

[0012] In this invention, the inclined surfaces of the first and second contact plates abut against the bottom edge of the main pipe, causing the riser to move closer to the center of the main pipe. Compared to existing technologies, this achieves automatic correction of the riser during the lifting process, which not only increases the installation speed of the air conditioning water main pipe in the vertical shaft of high-rise buildings but also reduces the labor intensity of manual operation. Simultaneously, during the rise of the riser, the bottom end of the main pipe pushes the folding plate outwards. The elasticity of the various torsion springs buffers the upward thrust of the riser, preventing accidental collision between the riser and the main pipe due to improper control of the winch's retraction.

[0018] 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.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a pipe installation mechanism in a vertical shaft, including a riser 1. The outer wall of the riser 1 is provided with a clamping sleeve 1 2 and a clamping sleeve 2 3. The clamping sleeve 1 2 and the clamping sleeve 2 3 are hinged to each other. The other end of the clamping sleeve 1 2 and the clamping sleeve 2 3 are connected by bolts. Workers can disassemble and tighten the mechanism to lift or loosen the riser 1, making it convenient for this mechanism to be used multiple times in the installation of different risers 1.

[0020] Both clamping sleeve 1 2 and clamping sleeve 2 3 are provided with hanging bases 4 on their outer walls. The two hanging bases 4 are fixedly connected to clamping sleeve 1 2 and clamping sleeve 2 3 respectively. Abutment plate 1 5 is provided above clamping sleeve 1 2 and fixedly connected thereto. Abutment plate 2 6 is provided above clamping sleeve 2 3 and fixedly connected thereto. The overall shape of abutment plate 1 5 and abutment plate 2 6 is an outwardly expanding arc surface. The inclined area of ​​abutment plate 1 5 and abutment plate 2 6 will resist the bottom of the main pipe during the rising process, thereby driving the riser 1 to align with the central axis of the main pipe.

[0021] Both clamping sleeve 1 (2) and clamping sleeve 2 (3) have grooves 7 on their walls. When clamping sleeve 1 (2) and clamping sleeve 2 (3) are closed, the ends of the two grooves 7 are connected to each other. The end of the riser 1 is located in the central area of ​​the groove 7. When the ends of the riser 1 and the main pipe are in contact, the workers can directly weld the joint between the riser 1 and the main pipe through the two closed grooves 7. For the welding work at the connection between clamping sleeve 1 (2) and clamping sleeve 2 (3), the clamping sleeve 1 (2) and clamping sleeve 2 (3) can be removed before welding. This method can ensure that welding work can be carried out in a stable environment, thereby improving welding quality and efficiency.

[0022] Furthermore, the outer walls of clamping sleeve 1 2 and clamping sleeve 2 3 are provided with multiple folding plates 8. The folding plates 8 are L-shaped. The inside of the folding plate 8 is provided with a fixed shaft 9 and fixedly connected to it. The outside of the fixed shaft 9 is provided with a fixed block 10 and rotatably connected to it. There are multiple fixed blocks 10 and they are divided into two groups. The two groups of fixed blocks 10 are fixedly connected to clamping sleeve 1 2 and clamping sleeve 2 3 respectively. A torsion spring is provided between the fixed block 10 and the fixed shaft 9. The two ends of the torsion spring are fixedly connected to the fixed block 10 and the fixed shaft 9 respectively. Under normal conditions, the spring force of the torsion spring rotates the folding plate 8 perpendicular to the central axis of the riser 1. Multiple equidistant convex strips 11 are provided above the folding plate 8 and are fixedly connected to it. During the process of the riser 1 rising, the bottom end of the main pipe contacts the surface of the convex strip 11.

[0023] Working principle:

[0024] In use, the riser 1 is first secured using clamping sleeve 2 and clamping sleeve 3. Then, the two lifting seats 4 are connected to the hooks of the winch, causing the winch to drive the riser 1 upward. During the upward movement, the inclined surfaces of the contact plates 5 and 6 will contact the bottom edge of the main pipe, and gradually, driven by the resisting force, the riser 1 will move towards the center of the main pipe until the central axis of the riser 1 coincides with that of the main pipe. Compared with existing technologies, this method achieves automatic correction of the riser 1 during the lifting process, which not only improves the installation speed of the main air conditioning water pipe in the vertical shaft of high-rise buildings, but also reduces the labor intensity of manual operation.

[0025] Simultaneously, during the ascent of riser 1, the bottom end of the main pipe will contact the surface of the protrusion 11. The folding plate 8 will gradually be squeezed outward by the main pipe and rotate. During this process, the elastic force of each torsion spring will buffer the thrust of riser 1, preventing accidental collision between riser 1 and main pipe due to the winch not controlling the degree of retraction properly. On the other hand, when the bottom end of the main pipe contacts the surface of protrusion 11, the operator can also manually rotate clamping sleeve 1 2 and clamping sleeve 2 3, thereby causing protrusion 11 to slightly polish the surface of the bottom end of the main pipe, cleaning the dust or gravel at the bottom end, which is more conducive to subsequent welding work.
