[0006] The HVAC pipe hoisting and installation structure for a building construction project provided in this application adopts the following technical solution:

[0007] A HVAC pipe hoisting and installation structure for a building construction project, comprising a bottom support ring, a bracket fixed to the top of the bottom support ring, and an upper clamping ring located between the bracket and the bottom support ring, wherein the upper clamping ring can move in a vertical direction, and the pipe is placed on the bottom support ring, and the vertical position of the upper clamping ring is adjusted to clamp and fix the pipe;

[0009] By adopting the above technical solution, the pipeline is placed inside the bottom support ring, and the pipeline is lifted at this time. Then the hand wheel is turned to drive the bidirectional screw to rotate. The bidirectional screw drives the two nut blocks to approach each other, and the two nut blocks drive the corresponding connecting rods to move. The connecting rods push the upper clamping ring to move downward and contact with the outer surface of the pipeline, so that the pipeline is quickly and stably clamped and fixed. This fixing method is relatively simple and convenient, and there is no need to lift the pipeline for a long time during operation.

[0010] Preferably, at least two sets of guide components are arranged between the inner top wall of the bracket and the upper clamping ring, and the guide components include a sleeve fixed to the top of the upper clamping ring and an insertion rod movably inserted inside the sleeve, and the upper end of the insertion rod is fixedly connected to the inner top wall of the bracket.

[0011] By adopting the above technical solution, when the upper clamping ring moves in the vertical direction, the insertion rod slides inside the insertion sleeve, and the cooperation between the insertion rod and the insertion sleeve realizes linear guidance of the upper clamping ring, ensuring that the upper clamping ring can only move in the vertical direction.

[0013] By adopting the above technical solution, the positioning rod can move vertically inside the positioning sleeve, thereby adjusting the vertical installation position of the pipeline, and the position between the positioning rod and the positioning sleeve is locked by the locking assembly, thereby locking the vertical height of the pipeline.

[0014] Preferably, the locking assembly includes a positioning plate fixed to the top of the bracket, the side wall of the positioning plate is fixedly connected to two limit rods, the two limit rods are movably sleeved with L-shaped inserts, a spring is fixedly connected between the L-shaped inserts and the positioning plate, the positioning rod is provided with second sockets distributed at equal distances, the side wall of the positioning sleeve is provided with a first socket, and the end of the L-shaped insert passes through the first socket and is inserted into the second socket.

[0015] By adopting the above technical solution, after the relative position between the positioning rod and the positioning sleeve is adjusted, the first socket and the second socket correspond to each other. At this time, the L-shaped insertion strip is loosened, and the spring releases its elastic force, pushing the L-shaped insertion strip toward the positioning rod, so that the end of the L-shaped insertion strip passes through the first socket and is inserted into the second socket.

[0016] Preferably, the spring is sleeved on a limiting rod, and the limiting rod is a cylindrical rod.

[0017] By adopting the above technical solution, a limiting rod is provided to achieve the purpose of guiding the L-shaped insert, so that the L-shaped insert can only move along a straight line, and the limiting rod is a cylindrical rod structure to ensure that the spring fully releases its elastic force.

[0018] Preferably, positioning holes are provided at both ends of the top strip.

[0019] By adopting the above technical solution, fasteners such as expansion bolts are arranged inside the positioning holes, and the top strip is fixedly installed on the top of the wall, thereby achieving the positioning purpose of the entire device.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] Place the pipe inside the bottom support ring, and then lift the pipe. Then turn the hand wheel to drive the bidirectional screw to rotate. The bidirectional screw drives the two nut blocks to move closer to each other. The two nut blocks drive the corresponding connecting rods to move. The connecting rods push the upper clamping ring to move downward and contact with the outer surface of the pipe, quickly and stably clamping and fixing the pipe. This fixing method is relatively simple and convenient, and there is no need to manually lift the pipe for a long time during operation.

[0022] When the relative position between the positioning rod and the positioning sleeve is adjusted, the first socket and the second socket are in corresponding position. At this time, the L-shaped insert is loosened, and the spring releases its elastic force, pushing the L-shaped insert toward the positioning rod, so that the end of the L-shaped insert passes through the first socket and is inserted into the second socket. At this time, the position between the positioning rod and the positioning sleeve is locked, and the vertical height of the pipeline is also locked. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following is combined with Figure 1-4 This application is described in further detail.

[0029] The embodiment of the present application discloses a HVAC pipe hoisting and installation structure for a building construction project, comprising a bottom support ring 1, a bracket 2 fixed to the top of the bottom support ring 1, and an upper clamping ring 7 located between the bracket 2 and the bottom support ring 1. The upper clamping ring 7 can move in a vertical direction, and a pipe 14 is placed on the bottom support ring 1. The vertical position of the upper clamping ring 7 is adjusted to clamp and fix the pipe 14.

[0030] A bidirectional screw rod 3 is rotatably inserted between the inner walls of the bracket 2, two nut blocks 5 are threadedly sleeved on the bidirectional screw rod 3, a connecting rod 6 is rotatably connected to the bottom of the nut block 5, and the lower end of the connecting rod 6 is rotatably connected to the top of the upper clamping ring 7, a guide rod 4 is fixedly connected between the inner walls of the bracket 2, the guide rod 4 movably passes through the two nut blocks 5, and one end of the bidirectional screw rod 3 is fixedly connected to a handwheel 8.

[0031] By adopting the above technical solution, the pipe 14 is placed inside the bottom support ring 1, and the pipe 14 is lifted at this time. Then, the hand wheel 8 is turned to drive the bidirectional screw 3 to rotate. The bidirectional screw 3 drives the two nut blocks 5 to approach each other. The two nut blocks 5 drive the corresponding connecting rod 6 to move. The connecting rod 6 pushes the upper clamping ring 7 to move downward and contact with the outer surface of the pipe 14, so that the pipe 14 is quickly and stably clamped and fixed. This fixing method is relatively simple and convenient, and there is no need to manually lift the pipe 14 for a long time during operation, which improves operating efficiency and reduces labor intensity.

[0032] Reference Figure 1 At least two sets of guide components 9 are arranged between the inner top wall of the bracket 2 and the upper clamping ring 7. The guide component 9 includes a sleeve 92 fixed to the top of the upper clamping ring 7, and an insertion rod 91 movably inserted into the sleeve 92. The upper end of the insertion rod 91 is fixedly connected to the inner top wall of the bracket 2.

[0033] When the upper clamping ring 7 moves in the vertical direction, the insertion rod 91 slides inside the insertion sleeve 92. The cooperation between the insertion rod 91 and the insertion sleeve 92 realizes linear guidance of the upper clamping ring 7, ensuring that the upper clamping ring 7 can only move in the vertical direction.

[0034] Reference Figure 1 At least two positioning sleeves 10, a positioning rod 11 movably inserted in the positioning sleeve 10, and a top strip 12 fixed to the top of the two positioning rods 11 are fixedly connected to the top of the bracket 2. A locking assembly 13 for locking the positioning rod 11 is provided on the top of the bracket 2.

[0035] The positioning rod 11 can move vertically inside the positioning sleeve 10 to adjust the vertical installation position of the pipeline 14, and the position between the positioning rod 11 and the positioning sleeve 10 is locked by the locking assembly 13, thereby locking the vertical height of the pipeline 14.

[0036] Reference Figure 4 The locking assembly 13 includes a positioning plate 1304 fixed to the top of the bracket 2, and two limiting rods 1302 are fixedly connected to the side wall of the positioning plate 1304. An L-shaped insert 1301 is movably sleeved on the two limiting rods 1302, and a spring 1303 is fixedly connected between the L-shaped insert 1301 and the positioning plate 1304. The positioning rod 11 is provided with second sockets 1101 distributed at equal distances, and the side wall of the positioning sleeve 10 is provided with a first socket 1001. The end of the L-shaped insert 1301 passes through the first socket 1001 and is inserted into the second socket 1101.

[0037] After the relative position between the positioning rod 11 and the positioning sleeve 10 is adjusted, the first socket 1001 and the second socket 1101 correspond to each other. At this time, the L-shaped insert 1301 is loosened, and the spring 1303 releases its elastic force, pushing the L-shaped insert 1301 toward the positioning rod 11, so that the end of the L-shaped insert 1301 passes through the first socket 1001 and is inserted into the second socket 1101.

[0038] Reference Figure 4 The spring 1303 is sleeved on the limit rod 1302, and the limit rod 1302 is a cylindrical rod. The limit rod 1302 is set to achieve the purpose of guiding the L-shaped insert 1301, so that the L-shaped insert 1301 can only move along a straight line, and the limit rod 1302 is a cylindrical rod structure to ensure that the spring 1303 fully releases the elastic force. The cylindrical limit rod 1302 can reduce the friction and wear when contacting the L-shaped insert 1301, thereby improving the stability and durability of the system.

[0039] Reference Figure 1 Positioning holes 1201 are provided at both ends of the top strip 12, and fasteners such as expansion bolts are arranged inside the positioning holes 1201 to fix the top strip 12 on the top of the wall, thereby achieving the positioning purpose of the entire device.

[0040] The implementation principle of a HVAC pipe hoisting and installation structure for a building construction project in an embodiment of the present application is as follows:

[0041] The positioning rod 11 can move vertically inside the positioning sleeve 10, so as to adjust the vertical installation position of the pipe 14. After the relative position between the positioning rod 11 and the positioning sleeve 10 is adjusted, the first socket 1001 and the second socket 1101 correspond to each other. At this time, the L-shaped inserting strip 1301 is loosened, and the spring 1303 releases its elastic force, pushing the L-shaped inserting strip 1301 to move toward the positioning rod 11, so that the end of the L-shaped inserting strip 1301 passes through the first socket 1001 and is inserted into the second socket 1101.

[0042] Then place the pipe 14 inside the bottom support ring 1, and then lift the pipe 14, and then turn the hand wheel 8 to drive the bidirectional screw 3 to rotate, and the bidirectional screw 3 drives the two nut blocks 5 to approach each other, and the two nut blocks 5 drive the corresponding connecting rod 6 to move, and the connecting rod 6 pushes the upper clamping ring 7 to move downward, and contacts with the outer surface of the pipe 14, and quickly and stably clamps and fixes the pipe 14. This fixing method is relatively simple and convenient, and there is no need to lift the pipe 14 for a long time during operation, which improves operating efficiency and reduces labor intensity.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
