Description
Technical Field
[0001] This utility model belongs to the field of HVAC installation and construction technology, specifically an auxiliary device for HVAC installation and construction. Background Technology
[0002] In HVAC installation, the performance of auxiliary equipment directly affects construction efficiency and quality. Currently, some auxiliary equipment designed for specific functions has emerged on the market, but these devices often only solve single problems and cannot meet the diverse needs of complex working conditions. For example, some equipment lacks integrated design in functions such as drilling, fixing, or angle adjustment, leading to frequent tool changes or equipment adjustments during construction, which affects overall efficiency.
[0003] For example, the Chinese invention patent (publication number: CN114932633B) discloses "A heating, ventilation, and air conditioning installation and construction equipment and its usage method," which includes a compression mechanism and an anti-overflow mechanism. The compression mechanism is used to reduce the amount of mud and sand seeping from the wall around the drill hole, and the anti-overflow mechanism filters the seeping mud and sand through a sponge ring, thereby reducing or avoiding damage to the wall surface caused by mud and water during drilling. This application mainly addresses the problem of mud and water overflow during drilling and provides an effective solution; however, this design does not include other auxiliary functions such as equipment fixation and angle adjustment, making it difficult to fully meet construction needs.
[0004] For example, the Chinese invention patent (publication number: CN111006327B) discloses "An installation frame and its construction method for a BIM-based HVAC design system," which includes a base frame, a support plate, and a sunshade. The base frame is bolted together to achieve structural stability, the support plate supports the equipment, and the sunshade is hinged to optimize wind resistance. While this application demonstrates excellent stability and sunshade functionality, it offers limited support for equipment positioning and angle adjustments during construction, failing to adequately adapt to diverse construction scenarios.
[0005] The aforementioned problems indicate that existing HVAC installation auxiliary equipment still has room for improvement in terms of functional integration and ease of operation. Therefore, this utility model proposes an auxiliary equipment for HVAC installation, aiming to improve construction efficiency and precision through multi-functional integrated design, meeting the modern industrial demand for efficient and intelligent auxiliary equipment.

[0011] As a preferred technical solution of this application, the clamping mechanism further includes a locking knob, which passes through the fixing base and is threadedly connected to the gripper. By rotating the locking knob, the gripper is tightened inward, thereby achieving a firm grip on the target object. The inner side of the gripper is provided with an anti-slip pad, which is made of a high-friction coefficient material to enhance clamping stability.
[0012] As a preferred technical solution of this application, a positioning pin is provided in the slide groove of the support arm.

[0013] As a preferred technical solution of this application, the angle adjustment component further includes a handwheel, which is fixed to one end of the screw, and rotating the handwheel drives the screw to rotate. The outer side of the handwheel is provided with anti-slip texture to improve grip stability during operation.

[0024] This utility model provides an auxiliary device for HVAC installation and construction, the overall structure of which is as follows: Figure 1 As shown, the system includes a multi-station adjustment module 1, a positioning module 2, and a power transmission module 3. The top of the multi-station adjustment module 1 has a connecting bracket 20, which is fixedly connected to the fixed seat 7 in the positioning module 2 by bolts. The power transmission module 3 is located inside the multi-station adjustment module 1; one end of its input shaft 10 is connected to an external drive device, and the other end transmits power to the rotating disk 4 of the multi-station adjustment module 1 through a gear set. The specific structure and operating principle of each module are described in detail below with reference to the accompanying drawings.
[0025] The core components of the multi-station adjustment module 1 include a rotary disk 4, a support arm 5, and an angle adjustment assembly 6, such as... Figure 2As shown. A gear ring is provided on the circumferential side of the rotating disk 4. The gear ring meshes with the transmission gear 11 in the power transmission module 3. The transmission gear 11 is fixed to the inner wall of the housing of the multi-position adjustment module 1 via bearings. When an external drive device drives the active gear to rotate via the input shaft 10, the active gear meshes with the transmission gear 11. The transmission gear 11 further drives the driven gear to mesh with the gear ring via the output shaft 12, thereby achieving a 360° rotation of the rotating disk 4. A ball bearing 19 is provided at the bottom of the rotating disk 4. The ball bearing 19 is embedded inside the housing of the multi-position adjustment module 1. Its outer ring is interference-fitted with the inner wall of the housing, and its inner ring is clearance-fitted with the bottom surface of the rotating disk 4 to reduce frictional resistance when the rotating disk 4 rotates. One end of the support arm 5 is connected to the rotating disk 4 via a hinge, and the other end is provided with a slide groove 13. A slider 14 that can slide along its length is provided in the slide groove 13. The slider 14 is connected to the guide sleeve 16 via a screw 15. The screw 15 passes through the guide sleeve 16 and is threadedly connected to the slider 14. When the operator turns the handwheel 18, the handwheel 18 drives the screw 15 to rotate. The screw 15, through its threaded action, pushes the slider 14 to move along the slide groove 13, thereby adjusting the angle of the support arm 5. The bottom surface of the slide groove 13 has scale lines to visually display the movement distance of the slider 14, facilitating precise adjustment of the support arm 5's position. Furthermore, a positioning pin is provided within the slide groove 13. The positioning pin passes through the slider 14 and is threadedly connected to the side wall of the slide groove 13. Tightening the positioning pin restricts the movement of the slider 14, thus fixing the angle of the support arm 5.
[0026] The structure of positioning module 2 is as follows Figure 3 As shown, its core components include a fixed base 7, a clamping mechanism, and a limiting plate 9. The fixed base 7 is fixedly connected to the connecting bracket 20 by bolts. The clamping mechanism is located at the bottom of the fixed base 7 and includes two opposing grippers 8, which are elastically connected to the fixed base 7 by spring plates. The two ends of the spring plates are welded to the grippers 8 and the fixed base 7 respectively, ensuring that the grippers 8 remain open in the initial state. The limiting plate 9 is located on both sides of the clamping mechanism to limit the maximum opening and closing range of the grippers 8 and prevent clamping failure due to excessive opening. The clamping mechanism also includes a locking knob 17, which passes through the fixed base 7 and is threadedly connected to the grippers 8. By rotating the locking knob 17, the grippers 8 are tightened inward, thereby achieving a firm clamping of the target object. The inner side of the grippers 8 is provided with an anti-slip pad made of a high-friction coefficient material to enhance clamping stability. When it is necessary to clamp the target object, the operator first manually adjusts the position of the gripper 8 to make it contact the target object, and then rotates the locking knob 17 to gradually tighten the gripper 8 until the target object is firmly clamped.
[0027] The transmission structure of power transmission module 3 is as follows: Figure 4As shown, its core components include an input shaft 10, a transmission gear 11, and an output shaft 12. One end of the input shaft 10 is connected to an external drive device, and the other end is equipped with a drive gear, which meshes with the transmission gear 11. The transmission gear 11 is fixed to the inner wall of the housing of the multi-position adjustment module 1 by bearings. One end of the output shaft 12 is coaxially connected to the transmission gear 11, and the other end is equipped with a driven gear, which meshes with the gear ring of the rotating disk 4. When the external drive device is started, the input shaft 10 drives the drive gear to rotate. The drive gear transmits power to the transmission gear 11 through the meshing relationship. The transmission gear 11 further transmits power to the driven gear through the output shaft 12, and finally the driven gear drives the rotating disk 4 to rotate. The entire power transmission process is completed through the coordinated work of the gear set and linkage mechanism, ensuring the high efficiency and stability of power transmission.
[0028] Details of the slide groove 13 of the support arm 5 are as follows Figure 4 As shown, the slide groove 13 contains a slider 14, a locating pin, and graduated lines. The slider 14 is connected to the guide sleeve 16 via a screw 15. Thrust bearings are provided at both ends of the guide sleeve 16 to reduce friction when the screw 15 rotates. Graduated lines are provided on the bottom surface of the slide groove 13 to visually display the movement distance of the slider 14, facilitating precise adjustment of the support arm 5 by the operator. When adjusting the angle of the support arm 5, the operator first loosens the locating pin, then rotates the handwheel 18. The handwheel 18 drives the screw 15 to rotate, and the screw 15 pushes the slider 14 along the slide groove 13 through its thread, thereby adjusting the angle of the support arm 5. After adjustment, the operator tightens the locating pin to restrict the movement of the slider 14, thus fixing the angle of the support arm 5.
[0029] The top of the connecting bracket 20 is provided with a mounting hole for fixed connection with an external construction platform. A rubber washer is installed in the mounting hole, which is embedded in the mounting hole with an interference fit to buffer the impact of external vibration on the equipment. The connecting bracket 20 is fixedly connected to the fixing seat 7 with bolts to ensure a stable and reliable connection between the positioning module 2 and the multi-position adjustment module 1.
[0030] The working process of this utility model is as follows: First, the equipment is fixed to the external construction platform through the mounting holes of the connecting bracket 20. Then, the position and angle of the rotating disk 4 and the support arm 5 of the multi-station adjustment module 1 are adjusted according to the construction requirements. The power transmission module 3 is started by the external drive device. The input shaft 10 drives the drive gear to rotate. The drive gear transmits power to the rotating disk 4 through the transmission gear 11 and the output shaft 12, realizing the 360° rotation of the rotating disk 4. At the same time, the operator adjusts the angle of the support arm 5 by turning the handwheel 18 and fixes the position of the support arm 5 by tightening the positioning pin. In the positioning module 2, the operator manually adjusts the position of the gripper 8 to make it contact the target object, and then rotates the locking knob 17 to tighten the gripper 8, thereby achieving a firm grip on the target object. Throughout the construction process, the equipment can flexibly adjust the working angle and position through the coordinated work of the multi-station adjustment module 1, the positioning module 2 and the power transmission module 3, ensuring accurate positioning and efficient operation during the construction process.
[0031] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.
[0032] During HVAC installation, precise positioning and angle adjustment of the equipment are necessary to adapt to different operating conditions. First, the equipment is fixed to the external construction platform through the mounting holes of the connecting bracket 20, with rubber washers embedded in the holes to buffer vibration. Then, bolts are used to tightly connect the fixing seat 7 to the connecting bracket 20, ensuring the stability of the entire equipment. At this point, the multi-position adjustment module 1, positioning module 2, and power transmission module 3 are ready for the next step.
[0033] When adjusting the working angle of the equipment, the external drive device is activated. The input shaft 10 drives the drive gear to rotate. After the drive gear meshes with the transmission gear 11, the power is transmitted to the gear ring of the rotating disk 4 through the output shaft 12, thereby driving the rotating disk 4 to rotate 360°. In this process, the ball bearing 19 plays a key role. Its outer ring is interference-fitted with the inner wall of the housing, and its inner ring is clearance-fitted with the bottom surface of the rotating disk 4, effectively reducing the frictional resistance when the rotating disk 4 rotates, ensuring smooth and stable rotation. At the same time, the angle of the support arm 5 needs to be fine-tuned according to the construction requirements. The operator turns the handwheel 18, which pushes the slider 14 along the slide groove 13 through the screw 15. The scale lines in the slide groove 13 can visually display the displacement distance of the slider 14, facilitating precise adjustment of the angle of the support arm 5. After the angle adjustment is completed, the positioning pin in the slide groove 13 is tightened to restrict the movement of the slider 14, thereby fixing the position of the support arm 5.
[0034] During the operation of positioning module 2, the gripper 8 is initially opened by a spring plate. The operator manually adjusts the position of the gripper 8 to make it contact the target object, and then rotates the locking knob 17. The locking knob 17 pushes the gripper 8 inward through the thread action until the target object is firmly clamped. The anti-slip pad on the inner side of the gripper 8 is made of a high-friction coefficient material, which can effectively enhance the clamping stability and prevent the target object from sliding or loosening during construction. Limiting plates 9 are set on both sides of the clamping mechanism to limit the maximum opening and closing range of the gripper 8 and avoid clamping failure due to excessive opening.
[0035] The power transmission module 3 plays a crucial role in power distribution throughout the construction process. The input shaft 10 receives power from the external drive unit, meshes with the transmission gear 11 via the drive gear, and then transmits the power to the driven gear via the output shaft 12, ultimately driving the rotating disk 4 to complete its rotation. The transmission gear 11 is fixed to the inner wall of the multi-position adjustment module 1's housing by bearings, ensuring the gear set maintains stability and efficiency during high-speed operation. Furthermore, the thrust bearings at both ends of the guide sleeve 16 reduce friction during screw 15 rotation, further improving the smoothness of angle adjustment.
[0036] In actual construction scenarios, such as drilling holes in HVAC ducts, the equipment can begin operation after completing the positioning and angle adjustment steps described above. The 360° rotation function of the rotary table 4 allows the drilling tool to flexibly switch positions in the horizontal direction, while the angle adjustment of the support arm 5 meets the precise positioning requirements in the vertical direction. The clamping mechanism firmly fixes the target object, ensuring that there is no displacement or shaking during construction. Through the coordinated work of the multi-station adjustment module 1, positioning module 2, and power transmission module 3, the equipment can quickly adapt to diverse needs under complex working conditions, significantly improving construction efficiency and accuracy.
[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
