Description

Technical Field

[0001] This invention relates to the field of duct installation technology, and in particular to a duct installation structure. Background Technology

[0002] The existing ductwork is installed using a mobile lifting trolley. During installation, the first connector is first installed on the ceiling according to the design position based on the drawings. Then, the second connector is installed on the ductwork, ensuring that the positions of the first and second connectors correspond. The ductwork is then placed on the mobile lifting trolley, which raises it to the design height. The trolley is then adjusted to align the second connector with the first connector. Finally, bolts are used to secure the first and second connectors together. This completes the installation of one section of ductwork. The installation of the next section is carried out in the same manner. After installation, adjacent sections of ductwork are fixed together with bolts to prevent air leakage between ducts.

[0003] Existing duct installation methods require high installation precision. Specifically, during installation, measuring instruments are needed to locate the positions of the first and second connectors. If the positional error of the first and second connectors is large, they will not align, leading to duct installation failure. This requires repositioning the first and second connectors and then reinstalling the duct, which reduces installation efficiency. Summary of the Invention

[0004] To address the shortcomings of existing duct installation methods, which suffer from low installation efficiency, this invention proposes a duct installation structure that facilitates positioning and improves duct installation efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A duct installation structure includes several mounting components; each mounting component includes an upper connector that can be installed on the lower side of a ceiling, a lower connector for supporting the duct, and a traction rope disposed between the upper and lower connectors; several winding wheels are rotatably connected inside the upper connector, and several positioning grooves are provided on the lower side of the upper connector; the upper end of the traction rope passes through the positioning grooves and is connected to the winding wheels; several positioning keys are fixedly connected to the upper side of the lower connector and are connected to the lower end of the traction rope; the positioning keys are located directly below the positioning grooves under the action of gravity; rotating the winding wheels winds the traction rope, causing the positioning keys to move upward and insert into the positioning grooves. The upper connector is provided with a first fixing mechanism for fixing the positioning key in the positioning groove. The air duct can move relative to the lower connector along the length direction of the air duct. The air duct installation structure also includes a second fixing mechanism for fixing the air duct to the lower connector, and a guide rod. The upper connector is provided with a guide hole. When the upper connector is installed on the lower side of the ceiling, the guide rod passes through the guide hole and is slidably connected with the guide hole. The guide rod is parallel to the ceiling and parallel to the extension direction of the air duct. When an adjacent upper connector is installed on the lower side of the ceiling, the upper connector is sleeved on the guide rod so that the upper connectors are arranged in a straight line.

[0007] With the above settings, the upper connector can be positioned using the guide rod, ensuring that the upper connector is arranged in a straight line. This guarantees that the duct is aligned in the same direction after being lifted, making the positioning of the upper connector more efficient. Furthermore, there is no need to separately position the lower connector. The positioning key automatically adjusts to the bottom of the positioning slot under gravity. After the traction rope drives the lower connector upwards, the positioning key smoothly inserts into the positioning slot, completing the engagement of the upper and lower connectors and further improving the installation efficiency of the duct. Additionally, when the duct is placed on the lower connector, there is no need to pay attention to the position of the lower connector supporting the duct. After the lower and upper connectors are fixed together, the duct can move relative to the lower connector along its length, facilitating docking with adjacent ducts. After docking, the second fixing mechanism can then be used to fix the duct to the lower connector, further improving the installation efficiency of the duct.

[0008] Furthermore, the upper connector includes two mounting seats that can be installed on the lower side of the ceiling, a rotating shaft rotatably connected between the mounting seats, a guide hole provided on the mounting seat, a winding wheel rotatably connected in each mounting seat, the winding wheel and the rotating shaft being drivenly connected, and a positioning groove provided on the lower side of the mounting seat.

[0009] In this application, the installation is further simplified by rotating a shaft to drive multiple winding wheels to rotate, which in turn drives the traction rope to lift the air duct.

[0010] Furthermore, the rotating shaft and the winding wheel are rotatably connected, a torsion spring is sleeved on the rotating shaft, and the winding wheel is connected to the rotating shaft through the torsion spring.

[0011] With the above settings, each positioning key can be fully inserted into the positioning slot.

[0012] Furthermore, the upper end of the positioning groove is provided with a limiting hole for limiting the traction rope, and the traction rope passes through the limiting hole.

[0013] With the above settings, the traction rope will not swing left and right when the winding wheel winds the traction rope, making the air duct more stable when it is lifted upward, and thus allowing the positioning key to be smoothly inserted into the positioning slot.

[0014] Furthermore, the upper side of the positioning key is provided with a chamfer to facilitate insertion into the positioning slot.

[0015] Furthermore, the first fixing mechanism includes a fixing bolt that is threadedly connected to the mounting base, and when the fixing bolt fixes the positioning key, the fixing bolt and the positioning key abut against each other.

[0016] With the above settings, after the positioning key is inserted into the positioning slot, tightening the fixing bolt will fix the positioning key in the positioning slot.

[0017] Furthermore, the lower connector includes a support roller that supports the lower side of the duct, a connecting rod rotatably connected to both ends of the support roller, a positioning key fixedly connected to the upper end of the connecting rod, and a second fixing mechanism including a screw, nuts at both ends of the screw, and a locking bolt for locking the support roller onto the connecting rod. When the lower connector supports the duct, the duct and the support roller abut against each other, and the duct is located between the connecting rods. When the second fixing mechanism fixes the duct, both ends of the screw are located on the upper side of the duct, both ends of the screw pass through the connecting rod, and the nuts are threadedly connected to both ends of the screw, so that the connecting rod presses against the duct.

[0018] With the above configuration, when the lower connector supports the duct, the resistance is smaller when the duct and the lower connector move relative to each other, and the connecting rod is located on opposite sides of the duct, resulting in better duct stability.

[0019] Furthermore, the locking bolt includes a stud and a bolt head. The stud and the support roller are coaxially arranged. The bolt passes through the connecting rod and is threadedly connected to the support roller. The bolt head is located on the side of the connecting rod away from the support roller. When the locking bolt locks the support roller, the bolt head and the side of the connecting rod away from the support roller abut against each other.

[0020] Furthermore, both ends of the air duct are fixedly connected with outwardly extending flanges, and the flanges of two adjacent air ducts are attached to each other and fixedly connected by fasteners. Attached Figure Description

[0029] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0030] See Figures 1 to 8A duct installation structure includes several mounting components. Each mounting component includes an upper connector 111 that can be installed on the lower side of a ceiling 21, a lower connector 112 for supporting the duct 22, and a traction rope 113 disposed between the upper connector 111 and the lower connector 112. Several winding wheels 114 are rotatably connected within the upper connector 111. Several positioning grooves 115 are provided on the lower side of the upper connector 111. The upper end of the traction rope 113 passes through the positioning grooves 115 and connects to the winding wheels 114. Several positioning keys 116 are fixedly connected to the upper side of the lower connector 112 and connected to the lower ends of the traction rope 113. Under the action of gravity, the positioning keys 116 are located directly below the positioning grooves 115. Rotating the winding wheels 114 winds the traction rope 113, causing the positioning keys 116 to move upwards and insert into the positioning grooves 115. Inside, the upper connector 111 is provided with a first fixing mechanism 117 that fixes the positioning key 116 in the positioning groove 115. The air duct 22 can move relative to the lower connector 112 along the length direction of the air duct 22. The air duct installation structure also includes a second fixing mechanism 12 for fixing the air duct 22 on the lower connector 112, and a guide rod 13. The upper connector 111 is provided with a guide hole 1111. When the upper connector 111 is installed on the lower side of the ceiling 21, the guide rod 13 passes through the guide hole 1111 and is slidably connected with the guide hole 1111. The guide rod 13 is parallel to the ceiling 21 and parallel to the extension direction of the air duct 22. When an adjacent upper connector 111 is installed on the lower side of the ceiling 21, the upper connector 111 is sleeved on the guide rod 13 so that the upper connector 111 is arranged in a straight line.

[0031] With the above settings, the upper connector 111 can be positioned by the guide rod 13, ensuring that the upper connector 111 is arranged in a straight line, thereby ensuring that the direction of the duct 22 is consistent after it is lifted. The positioning efficiency of the upper connector 111 in this application is higher. In addition, there is no need to position the lower connector 112 separately. The positioning key 116 automatically adjusts to be directly below the positioning groove 115 under the action of gravity. After the traction rope 113 drives the lower connector 112 upward, the positioning key 116 can be smoothly inserted into the positioning groove 115, completing the connection between the upper connector 111 and the lower connector 112. The cooperation of component 112 further improves the installation efficiency of duct 22. In addition, when duct 22 is placed on the lower connector 112, there is no need to pay attention to the position of the lower connector 112 supporting duct 22. After the lower connector 112 and the upper connector 111 are fixed together, duct 22 can move relative to the lower connector 112 along the length of duct 22, which facilitates docking with adjacent duct 22. After docking, the second fixing mechanism 12 can be used to fix duct 22 on the lower connector 112, which further improves the installation efficiency of duct 22.

[0032] Specifically, when installing the first duct 22, first install one of the aforementioned upper connectors 111 on the ceiling 21 according to the design requirements. After fitting another upper connector 111 onto the guide rod 13, install the upper connector 111 on the ceiling 21 as well. At this time, the lower connector 112 is directly below the upper connector 111 under the action of gravity, and the positioning key 116 is directly below the positioning groove 115. Then, place the duct 22 on the lower connector 112. See below. Figure 1 and Figure 2 Rotate the winding wheel 114, which winds the traction rope 113. The traction rope 113 lifts the lower connector 112 and the air duct 22. When the positioning key 116 is inserted into the positioning groove 115, the first fixing mechanism 117 fixes the positioning key 116 in the positioning groove 115. See [link / reference] Figure 4 and Figure 5 At this point, the lower connector 112 and the upper connector 111 are fixedly connected to prevent the duct 22 from falling down. At this time, the duct 22 can move relative to the lower connector 112 along the length of the duct 22 to adjust the position of the duct 22. Then, the second fixing mechanism 12 is used to fix the duct 22 on the lower connector 112. At this time, the duct 22 is fixed on the lower side of the ceiling 21.

[0033] When installing subsequent ducts 22, the upper connectors 111 can be positioned using the guide rod 13. Specifically, slide the guide rod 13 backward along its axial direction, then place the next upper connector 111 onto the guide rod 13 and fix it to the lower side of the ceiling 21. Continue sliding the guide rod 13 backward, then place the next upper connector 111 onto the guide rod 13 and fix it to the lower side of the ceiling 21. That is, after installing one upper connector 111, pull the guide rod 13 backward to install the next upper connector 111. This ensures that each installed upper connector 111 is aligned along the axis of the guide rod 13, i.e., each installed upper connector 111 is arranged in a straight line, guaranteeing the straightness of the duct 22 installation and greatly simplifying installation and positioning. After the upper connector 111 is installed, follow the same procedure as when installing the first duct 22, placing the duct 22 on the lower connector 112. See [link to procedure]. Figure 6 Then, rotate the winding wheel 114 to lift the air duct 22 and insert the positioning key 116 into the positioning slot 115. After the first fixing mechanism 117 fixes the lower connector 112 and the upper connector 111 together, see [link to previous steps]. Figure 7 At this point, the air ducts 22 are at the same height and aligned with each other. Move the air ducts 22 forward so that they abut and connect with the preceding air duct 22. Then, use the second fixing mechanism 12 to fix the air ducts 22 to the lower connector 112. (See below) Figure 8 .

[0034] In one implementation, the upper connector 111 includes two mounting seats 1112 that can be installed on the lower side of the ceiling 21, a rotating shaft 1113 rotatably connected between the mounting seats 1112, a guide hole 1111 provided on the mounting seats 1112, a winding wheel 114 rotatably connected in each mounting seat 1112, the winding wheel 114 and the rotating shaft 1113 being drivenly connected, and a positioning groove 115 provided on the lower side of the mounting seats 1112.

[0035] In this application, the installation is further simplified by rotating the shaft 1113 to drive multiple winding wheels 114 to rotate, which in turn drives the traction rope 113 to lift the air duct 22.

[0036] Specifically, one end of the rotating shaft 1113 can be rotated by an electric screwdriver or wrench; the mounting base 1112 can be fixed to the ceiling 21 by expansion screws.

[0037] In one implementation, the rotating shaft 1113 and the winding wheel 114 are rotatably connected, and a torsion spring 1114 is sleeved on the rotating shaft 1113. The winding wheel 114 is connected to the rotating shaft 1113 through the torsion spring 1114.

[0038] With the above settings, each positioning key 116 can be fully inserted into the positioning slot 115.

[0039] Specifically, when the rotating shaft 1113 rotates, the rotating shaft 1113 drives the winding wheel 114 to rotate through the torsion spring 1114. If one positioning key 116 is fully inserted into the positioning groove 115, but the other positioning key 116 has not been fully inserted into the positioning groove 115, the rotating shaft 1113 can continue to rotate so that the other positioning groove 115 is fully inserted into the positioning groove 115.

[0040] In one implementation, the upper end of the positioning groove 115 is provided with a limiting hole 1151 for limiting the traction rope 113, and the traction rope 113 passes through the limiting hole 1151.

[0041] With the above settings, when the winding wheel 114 winds the traction rope 113, the traction rope 113 will not swing left and right, making the air duct 22 more stable when it is lifted upward, so that the positioning key 116 can be smoothly inserted into the positioning groove 115.

[0042] As one implementation, the upper side of the positioning key 116 is provided with a chamfer 1161 to facilitate insertion into the positioning groove 115.

[0043] In one implementation, the first fixing mechanism 117 includes a fixing bolt that is threadedly connected to the mounting base 1112. When the fixing bolt fixes the positioning key 116, the fixing bolt and the positioning key 116 abut against each other.

[0044] With the above settings, after the positioning key 116 is inserted into the positioning groove 115, tightening the fixing bolt will fix the positioning key 116 in the positioning groove 115.

[0045] In one implementation, the lower connector 112 includes a support roller 1121 that supports the lower side of the duct 22, and a connecting rod 1122 rotatably connected to both ends of the support roller 1121. The positioning key 116 is fixedly connected to the upper end of the connecting rod 1122. The second fixing mechanism 12 includes a screw 121, nuts 122 disposed at both ends of the screw 121, and locking bolts 123 for locking the support roller 1121 onto the connecting rod 1122. When the lower connector 112 supports the duct 22, the duct 22 and the support roller 1121 abut against each other, and the duct 22 is located between the connecting rods 1122. When the second fixing mechanism 12 fixes the duct 22, both ends of the screw 121 are located on the upper side of the duct 22, and both ends of the screw 121 pass through the connecting rod 1122. The nuts 122 are threadedly connected to both ends of the screw 121, so that the connecting rod 1122 presses against the duct 22.

[0046] With the above settings, when the lower connector 112 supports the air duct 22, the resistance is smaller when the air duct 22 and the lower connector 112 move relative to each other, and the connecting rod 1122 is located on opposite sides of the air duct 22, resulting in better stability of the air duct 22.

[0047] Specifically, when the air duct 22 is moved, the support roller 1121 rotates, and the resistance to the movement of the air duct 22 is small. When it is necessary to fix the air duct 22 on the lower connector 112, the nut 122 is tightened. The nut 122 presses the connecting rod 1122, so that the connecting rod 1122 is pressed on the opposite sides of the air duct 22, that is, the air duct 22 is clamped by the connecting rod 1122.

[0048] In one implementation, the locking bolt 123 includes a stud 1231 and a bolt head 1232. The stud 1231 and the support roller 1121 are coaxially arranged. The bolt passes through the connecting rod 1122 and is threadedly connected to the support roller 1121. The bolt head 1232 is located on the side of the connecting rod 1122 away from the support roller 1121. When the locking bolt 123 locks the support roller 1121, the bolt head 1232 and the side of the connecting rod 1122 away from the support roller 1121 abut against each other.

[0049] When the locking bolt 123 is loosened, the support roller 1121 can rotate around the axis of the locking bolt 123. When the locking bolt 123 is tightened, the bolt head 1232 presses against the connecting rod 1122, and the support roller 1121 cannot rotate.

[0050] In one implementation, the two ends of the air duct 22 are fixedly connected with outwardly extending flanges 221, and the flanges 221 of two adjacent air ducts 22 are attached to each other and fixedly connected by fasteners.

[0051] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
