Description

Technical Field

[0001] This utility model relates to the field of HVAC maintenance equipment technology, specifically to an HVAC maintenance bracket. Background Technology

[0002] Heating, ventilation, and air conditioning (HVAC) is a comprehensive technical system in the field of building environmental control, mainly covering three core areas: heating, ventilation, and air conditioning. Its core objective is to create a safe, comfortable, and energy-efficient indoor building environment. During the maintenance of HVAC pipes, supports are needed to support the pipes.

[0003] Chinese patent document CN221583526U provides a pipe maintenance support frame, including a base plate, a movable plate provided at the center of the top wall of the base plate, and the movable plate being connected to the base plate through a first lifting assembly; a pair of support plates are fixedly connected to the top wall of the movable plate, and the two support plates are horizontally symmetrical about the movable plate; an arc-shaped placement groove is provided on the top wall of each pair of support plates.

[0004] However, the aforementioned maintenance support frame cannot secure the pipe during use, which can easily cause the pipe to fall off the support during maintenance. Furthermore, the support frame is only suitable for horizontal pipes and cannot be used for pipes with an inclined angle, which has certain limitations. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a heating and ventilation maintenance bracket that can be used for pipe support with an inclined angle, thereby improving the applicability of the bracket.

[0006] The objective of this utility model is achieved through the following technical solution: This HVAC maintenance bracket includes: The chassis is located above the base. A groove is opened on the top of the chassis. A rotating roller is rotatably connected to both the front and back sides of the groove. The maintenance pipe is supported on the rotating roller. Swing grooves are opened on both the left and right sides of the groove. Two swing arms are symmetrically arranged on the housing. Each swing arm is rotatably mounted on a corresponding swing groove. Roller grooves are opened on the opposite side of the two swing arms for rotating and mounting pressure rollers, which then press the maintenance pipe. A lifting assembly is installed between the base and the housing to drive the housing to move up and down relative to the base. The bottom of the housing is rotatably connected to the lifting assembly. An angle adjustment component is installed between the lifting component and the housing, and is used to drive the housing to rotate relative to the lifting component; A pushing component, installed between the swing arm and the pressure roller, drives the pressure roller to rotate, thereby pushing the maintenance pipe to slide along the rotating roller to achieve position adjustment; and The rotating assembly, installed between the housing and the swing arm, is used to drive the swing arm to rotate relative to the swing groove.

[0007] As a further technical solution, the lifting assembly includes a hollow column, a lifting column, a threaded rod, and a motor. The bottom of the hollow column is fixedly connected to the base, and the top of the hollow column is open. The lower end of the lifting column extends into the hollow column from the open. A threaded rod is also provided inside the hollow column. The bottom of the threaded rod is supported on the base, and the lower end of the lifting column is threadedly connected to the threaded rod. The motor drives the threaded rod to rotate through a transmission assembly, thereby driving the lifting column to move up and down along the hollow column.

[0008] As a further technical solution, the transmission assembly includes bevel gear A and bevel gear B. The motor is fixed on the outer wall of the hollow column, bevel gear A is installed at the lower end of the threaded rod, and the output shaft of the motor passes through the hollow column and is fitted with bevel gear B. Bevel gear B meshes with bevel gear A for transmission.

[0009] As a further technical solution, the angle adjustment component includes an electric telescopic rod, a set of lugs at the bottom of the housing, and a rotating pin installed at the upper end of the lifting column for rotatably connecting to the lugs. The fixed end of the electric telescopic rod is hinged to one side of the outer wall of the lifting column, and the free end of the electric telescopic rod is hinged to the bottom outer side of the housing. The extension and retraction of the electric telescopic rod drives the housing to rotate relative to the lifting column.

[0010] As a further technical solution, the driving component includes a knob and a hand-tightening screw integrated at the bottom of the knob. The hand-tightening screw passes through the swing arm and extends into the roller groove and is connected and fixed to the pressure roller, so that the pressure roller rotates synchronously when the knob is turned.

[0011] As a further technical solution, the rotating assembly includes a two-section worm gear disposed inside the housing. Both ends of the two-section worm gear extend out of the housing and are fitted with a crank handle. A worm wheel is disposed below each swing arm. The worm wheel meshes with the two-section worm gear and is supported inside the housing by a fixed shaft. The fixed shaft is welded and fixed to the bottom of the swing arm. When the crank handle is rotated, the fixed shaft drives the swing arm to rotate in the swing groove.

[0012] As a further technical solution, several casters are installed at the bottom of the base, and foot brakes are provided on the casters.

[0013] The beneficial effects of this utility model are as follows: 1. The push and rotate components can drive the swing arm and pressure roller to rotate, so that the pressure roller and rotating roller can clamp and fix the pipe. When the pipe is being maintained, it can prevent the pipe from falling off the support and improve the safety of the support during use. 2. The angle adjustment component (electric telescopic rod) can drive the housing to rotate relative to the lifting column, thereby changing the tilt angle of the housing, making the bracket suitable for supporting pipes with tilt angles, thus improving the applicability of the bracket; 3. The height of the chassis can be freely adjusted via the lifting mechanism, making it more versatile. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings: Example: As attached Figures 1-4 As shown, this HVAC maintenance bracket includes a base 1, a housing 2, a hollow column 3, a lifting column 4, a threaded rod 5, a bevel gear A 6, a motor 7, a bevel gear B 8, a rotating roller 9, a fixed shaft 10, a worm gear 11, a swing arm 12, a pressure roller 13, a double-section worm gear 14, a crank handle 15, a support lug 16, a hand-tightening screw 17, a knob 18, an electric telescopic rod 19, a roller groove 20, a groove 21, a swing groove 22, a rotating pin 23, and a caster 24.

[0020] Reference Appendix Figure 1 The housing 2 is positioned above the base 1. A groove 21 is formed on the top of the housing 2. A rotating rod 9 is rotatably connected to both the front and rear sides of the groove 21 to support the maintenance pipe on the rotating rod 9. At the same time, a swing groove 22 is formed on both the left and right sides of the groove 21.

[0021] Two swing arms 12 are symmetrically arranged on the housing 2, and each swing arm 12 is rotatably mounted on the corresponding swing groove 22. A roller groove 20 is opened on the opposite side of each of the two swing arms 12, and a pressure roller 13 is rotatably installed in the roller groove 20 to press the maintenance pipe.

[0022] Install a lifting assembly between base 1 and housing 2, such as Figure 3 As shown, the lifting assembly includes a hollow column 3, a lifting column 4, a threaded rod 5, and a motor 7. The bottom of the hollow column 3 is fixed to the base 1 by welding. The top of the hollow column 3 is open, and the lower end of the lifting column 4 extends into the hollow column 3 from the open end. A threaded rod 5 is also provided inside the hollow column 3. The bottom of the threaded rod 5 can be supported on the base 1 by a bearing (rotating relative to the base 1). The lower end of the lifting column 4 is threadedly connected to the threaded rod 5 (a nut can be welded on, and then threadedly connected to the threaded rod 5 through the nut). The motor 7 drives the threaded rod 5 to rotate through the transmission assembly, thereby driving the lifting column 4 to move up and down along the hollow column 3. This in turn drives the housing 2 to move up and down relative to the base 1. The bottom of the housing 2 is rotatably connected to the lifting assembly. Furthermore, the transmission assembly includes a bevel gear A6 and a bevel gear B8. The motor 7 is fixedly installed on the outer wall of the hollow column 3 by a flange (or it can be fixedly installed on the base 1). A bevel gear A6 is fixedly installed at the lower end of the threaded rod 5. A bevel gear B8 is installed after the output shaft of the motor 7 passes through the hollow column 3. The bevel gear B8 meshes with the bevel gear A6 for transmission. When the motor 7 is working, it drives the threaded rod 5 to rotate. The threaded rod 5 rotates relative to the nut on the lifting column 4, causing the lifting column 4 to move up and down, which in turn drives the housing 2 to move up and down relative to the base 1.

[0023] An angle adjustment component is installed between the lifting component and the housing 2, enabling the housing 2 to rotate relative to the lifting component. Furthermore, as... Figure 2 As shown, the angle adjustment assembly includes an electric telescopic rod 19 (using a commercially available standard product, the specific structure of which will not be described in detail). A set of lugs 16 are provided at the bottom of the housing 2, and a rotating pin 23 is installed at the upper end of the lifting column 4. The rotating pin 23 rotatably connects the top of the lifting column 4 to the lugs 16. The fixed end of the electric telescopic rod 19 is hinged to one side of the outer wall of the lifting column 4, while the free end of the electric telescopic rod 19 is hinged to the bottom outer side of the housing 2. The extension and retraction of the electric telescopic rod 19 causes the housing 2 to rotate relative to the lifting column 4.

[0024] The push assembly is installed between the swing arm 12 and the pressure roller 13, which can drive the pressure roller 13 to rotate, thereby pushing the maintenance pipe to slide along the rotating roller 9 to achieve position adjustment. Figure 4 As shown, the pushing component further includes a knob 18 and a hand screw 17 integrally connected to the lower part of the knob 18. The hand screw 17 passes through the swing arm 12 and extends into the roller groove 20 and is connected and fixed to the pressure roller 13, so that when the knob 18 is rotated, it drives the pressure roller 13 to rotate synchronously. When the maintenance pipe is in contact with the pressure roller 13, the knob 18 can be manually rotated to move the maintenance pipe using the pressure roller 13. When clamping the pipe, the pipe position can also be adjusted.

[0025] like Figure 4As shown, the rotating assembly is installed between the housing 2 and the swing arm 12, enabling the swing arm 12 to rotate relative to the swing groove 22. The rotating assembly includes a double-section worm gear 14 disposed inside the housing 2. Both ends of the double-section worm gear 14 extend out of the housing 2 and are fitted with a crank handle 15. The crank handle 15 drives the entire double-section worm gear 14 to rotate. Each swing arm 12 is provided with a worm wheel 11 below it (a clearance groove is provided on the swing arm 12 at the position corresponding to the worm wheel 11). The worm wheel 11 meshes with the double-section worm gear 14 and is supported in the housing 2 by a fixed shaft 10. At the same time, the bottom of the swing arm 12 is fixed to the surface of the fixed shaft 10 by welding. When the crank handle 15 rotates, the fixed shaft 10 drives the swing arm 12 to rotate in the swing groove 22.

[0026] Preferably, such as Figure 1 , 2 As described above, four casters 24 are installed at the bottom of the base 1, and foot brakes are provided on the casters.

[0027] The working process of this utility model: Move the bracket to the area below the pipe requiring repair. Activate the electric telescopic rod 19 via remote control. The electric telescopic rod 19 pushes upwards or downwards towards the side of the housing 2, adjusting the tilt angle of the housing 2 and the rotating roller 9. Then, start the motor 7. The output shaft of the motor 7 drives the bevel gear B8 to rotate. The rotation of the bevel gear B8 drives the bevel gear A6 and the threaded rod 5 to rotate. The rotation of the threaded rod 5 causes the lifting column 4, housing 2, and rotating roller 9 to rise, bringing the rotating roller 9 into contact with the bottom of the pipe. Next, manually turn the crank handle 15. The crank handle 15 drives the double-stage worm gear 14 to rotate. The rotation of the double-stage worm gear 14 drives the two worm wheels 11 to rotate, causing the swing arm 12 to rotate. This ensures that both pressure rollers 13 and the rotating roller 9 contact the pipe, clamping and fixing it in place. Finally, manually turn the knob 18 (hand-tightening screw 17) to rotate the pressure roller 13. The rotation of the pressure roller 13 allows for left and right movement of the pipe, enabling adjustment of the pipe's position while clamping it.
