Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fresh air system pipe hoisting, in particular to a fresh air system pipe hoisting structure and a hoisting method thereof. BACKGROUND

[0002] When hoisting the fresh air pipe in the building, the pipe is usually suspended below the hoisting surface through a suspension structure.

[0003] During installation, the pipe support is first fixedly connected to the hoisting surface at a predetermined interval, and the distance between the two adjacent pipe supports is less than the length of a single pipe segment; then the pipe is hoisted horizontally to one side of the pipe support, and the pipe is placed on the two pipe supports by horizontally pushing the pipe through the equipment, thereby completing the installation of a single pipe segment.

[0004] The above installation method cannot provide the space condition of hoisting the pipe to one side of the support when the space is relatively small, such as hoisting the fresh air pipe near the wall surface or the corner, and there is room for improvement. SUMMARY

[0005] In order to overcome the limitation of the narrow space on the installation of the air pipe, the present application provides a fresh air system pipe hoisting structure and a hoisting method thereof.

[0006] The fresh air system pipe hoisting structure and the hoisting method thereof provided by the present application adopt the following technical scheme:

[0007] A fresh air system pipe hoisting structure, comprising an air pipe and two spaced-apart hangers, the hangers being slidingly fitted to the hoisting surface along the length direction of the air pipe, a linkage rod being provided on the hanger, a power rod being slidingly fitted vertically on the hoisting surface, a transmission member being provided between the power rod and the linkage rod, the transmission member comprising a gear portion rotating horizontally on the hoisting surface, a vertical sawtooth provided on the power rod, and a horizontal sawtooth provided on the linkage rod, the horizontal sawtooth being arranged along the length direction of the air pipe, and the vertical sawtooth and the horizontal sawtooth both being engaged with the gear portion.

[0008] A limiting assembly is provided between the hoisting surface and the hanger, and when the two hangers move to the minimum distance, the limiting assembly limits the movement of the two hangers.

[0009] By adopting the technical scheme, when the air pipe is installed at a position with a relatively small space, the air pipe is hoisted vertically upward below the hangers by the hoisting device and the lifting ropes, the distance between the two hangers is greater than the length of the air pipe in the initial position, and the air pipe does not interfere with the hangers when being hoisted vertically upward between the two hangers; when the air pipe moves upward to abut against the power rod, a vertical upward force is applied to the power rod to drive the power rod to move vertically upward, thereby driving the gear part to rotate, the gear part drives the linkage rod to move, the two hangers move toward each other until the power rod moves to the highest point, at this time, the distance between the two hangers is the smallest, and the two ends of the air pipe pass out of the outer sides of the two hangers, respectively, and the limiting assembly limits the movement of the two hangers; the air pipe is lowered vertically by the hoisting device and the lifting ropes until the air pipe is placed on the hangers, thereby overcoming the limitation of the small space on the installation of the air pipe and achieving the installation of the air pipe.

[0010] Preferably, two groups of power rods are arranged at intervals, the power rods correspond to the linkage rods one by one, and the power rods and the linkage rods are arranged in a staggered manner.

[0011] By adopting the technical scheme, the power rods and the linkage rods are arranged one by one, which reduces the control accuracy of the power rods and reduces the occurrence of gear part jamming compared with arranging two groups of vertical sawteeth on the same power rod; and the staggered arrangement of the power rods and the linkage rods effectively compresses the overall volume of the hoisting structure, thereby achieving the miniaturization design of the hoisting structure.

[0012] Preferably, the limiting assembly comprises a limiting piece, a limiting block fixed to the hanger, and an outer limiting groove formed in the limiting block, and the bottom end of the limiting piece is provided with an outer limiting rod for plug-in cooperation with the outer limiting groove.

[0013] In the initial position, the top end of the hanger abuts against the limiting piece to limit the downward movement of the limiting piece, and when the two hangers move to the minimum distance, the hanger and the limiting piece are disengaged, so that the limiting piece falls under the action of gravity and the outer limiting rod is inserted into the outer limiting groove.

[0014] By adopting the technical scheme, when the hanger moves to be disengaged from the limiting piece, the limiting of the limiting piece is released, the limiting piece moves downward under the action of its own gravity, and the outer limiting rod is inserted downward into the outer limiting groove to limit the movement of the hanger.

[0015] Preferably, a lifting lug for the lifting rope is fixed to the air pipe.

[0016] Preferably, the lifting lug comprises two spaced-apart supporting plates, an inner limiting groove is formed between the two supporting plates, and the bottom end of the limiting piece is provided with an inner limiting rod for plug-in cooperation with the inner limiting groove.

[0017] By adopting the technical scheme, when the hanger moves away from the limiting piece, the limiting of the limiting piece is released, the limiting piece moves downward under the force of gravity, and the inner limiting rod is inserted into the inner limiting groove, thereby limiting the movement of the air pipe.

[0018] Preferably, the support plate and the limiting piece are pressed by the cooperation of the bolt and the nut.

[0019] By adopting the technical scheme, after the air pipe is lowered to abut against the hanger, the support plate and the limiting piece are locked by the cooperation of the bolt and the nut, thereby ensuring the stability of the air pipe during use.

[0020] Preferably, the inner edge of the top end of the support plate is provided with a slope.

[0021] By adopting the technical scheme, when the limiting piece is lowered, the bottom end of the limiting piece abuts against the slope, the air pipe is driven to move along the width direction, the air pipe is aligned, and the air pipe is centered, thereby facilitating the connection between different air pipe sections in the later period.

[0022] Preferably, the gear part includes a pinion for engaging with the vertical sawtooth and a large gear for engaging with the horizontal sawtooth, and the large gear and the pinion are coaxially fixed.

[0023] By adopting the technical scheme, by reasonably configuring the large gear and the pinion, the movement of the power rod for a short distance can drive the movement of the linkage rod for a long distance, and this is beneficial to the miniaturization of the hoisting structure.

[0024] A hoisting method of a fresh air system pipe hoisting structure includes the following steps:

[0025] S1, in the initial position, the distance between the two hangers is greater than the length of the air pipe, and the air pipe is vertically lifted upward directly below the hangers;

[0026] S2, the air pipe moves upward to abut against the power rod, the power rod moves vertically upward, thereby driving the gear part to rotate, the gear part drives the linkage rod to move, and the two hangers move in the direction of approaching each other;

[0027] S3, when the power rod moves to the highest point, the two hangers move to the minimum distance, and the two ends of the air pipe respectively pass out of the outer sides of the two hangers, and the limiting assembly limits the movement of the two hangers.

[0028] S4, the air pipe is vertically lowered to be placed on the hangers.

[0029] By adopting the technical scheme, by reasonably designing the hoisting structure and reasonably arranging the hoisting process, the hoisting of the air pipe in a narrow space is realized, the operability is high, and an effective reference is provided for subsequent similar projects.

[0030] Preferably, after the step S4, there is a gap between the upper surface of the air pipe and the lower surface of the power rod, and a wooden square and a rubber pad are inserted into the gap to fill the gap.

[0031] By adopting the technical scheme, the stability of the hoisting structure as a whole is improved, and the loosening of the hoisting structure under external force is reduced.

[0032] In summary, the present application has at least one of the following beneficial technical effects:

[0033] 1. By reasonably designing the hoisting structure and reasonably arranging the hoisting process, the hoisting of the air pipe in a narrow space is realized, which has high operability and provides an effective reference for subsequent similar projects.

[0034] 2. When the hanger moves away from the limiting piece, the limiting of the limiting piece is released, the limiting piece moves downward under the action of its own gravity, the outer limiting rod is inserted into the outer limiting groove, and the movement of the hanger is limited.

[0035] 3. When the hanger moves away from the limiting piece, the limiting of the limiting piece is released, the limiting piece moves downward under the action of its own gravity, the inner limiting rod is inserted into the inner limiting groove, and the movement of the air pipe is limited.

[0050] In combination with Figure 1 , Figure 4 and Figure 5 , the limiting assembly 6 is provided with multiple groups, and each group of limiting assembly 6 corresponds to the linkage rod 4 one by one.
