Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for chemical equipment maintenance, and in particular relates to a support device for chemical equipment maintenance. Background Technology

[0002] Chemical equipment requires regular maintenance during long-term operation to ensure its safe and stable operation. The maintenance process often requires multi-angle and multi-directional maintenance and replacement of equipment with complex structures, which places high demands on the support devices. Traditional maintenance support devices have problems such as non-adjustable support height, fixed angle, and poor stability.

[0003] Currently, most chemical equipment maintenance support devices are fixed structures, lacking rotation capabilities. This fails to meet the operational needs of different angles during maintenance, often requiring workers to frequently change support positions or adopt unsafe postures, increasing labor intensity and creating safety hazards. The few rotatable support devices commonly suffer from unreliable locking mechanisms, making the worktable angle prone to shifting due to vibration or external forces during maintenance. This not only affects maintenance quality but may also cause equipment damage or personal injury.

[0004] Existing adjustable support devices mostly employ manual screw lifting or hydraulic systems. The former is labor-intensive and lacks precision, while the latter is complex in structure, expensive, and difficult to maintain. Furthermore, most support devices lack a bottom anti-slip design, making them prone to slippage when supporting heavy chemical equipment components, posing a safety hazard. Utility Model Content

[0005] To address the technical problems existing in the background art, this utility model provides a support device for the maintenance of chemical equipment, which has the characteristics of multi-angle adjustment, height adjustment, and stability, thereby improving the efficiency of maintenance work while ensuring operational safety.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] A support device for the maintenance of chemical equipment includes a lifting device and a rotating mechanism. The rotating mechanism is positioned above the lifting mechanism and includes a connecting plate. A rotating shaft is fixedly connected to the top of the connecting plate, and a worktable is rotatably connected to the top of the rotating shaft. Multiple auxiliary rods arranged in a circumferential array are fixedly connected to the bottom of the worktable. A sliding ball is fixedly connected to the bottom of each auxiliary rod. An annular groove nested within the sliding ball is formed on the upper surface of the connecting plate. A locking mechanism is provided at the outer end of each auxiliary rod to fix the position of the worktable at different angles.

[0008] Optionally, the locking mechanism includes a locking nut threaded to the outer wall of the auxiliary rod, a locking sleeve slidably connected to the outer wall end of the auxiliary rod, with the top end of the locking sleeve contacting the locking nut, and multiple symmetrically arranged positioning teeth fixed to the bottom end of the locking sleeve. A retaining ring is fixedly connected to the outer end of the auxiliary rod, and a return spring is slidably connected to the outer end of the auxiliary rod. The end of the return spring near the retaining ring abuts against the retaining ring, and the end away from the retaining ring abuts against the locking sleeve. Multiple positioning grooves matching the positioning teeth are formed on the upper surface of the connecting plate.

[0009] Optionally, the inner wall of the locking sleeve is provided with multiple symmetrically arranged guide grooves, and the outer end of the retaining ring is fixedly connected with multiple guide strips that match the guide grooves.

[0010] Optionally, the lifting device includes a base, which is rotatably connected to two symmetrically arranged lower support arms via pins.

[0011] Optionally, each of the two lower support arms is hinged to an upper support arm at the end furthest from the base. The end of the upper support arm furthest from the lower support arm is rotatably connected to a top seat via a pin, and the top of the top seat is fixedly connected to the connecting plate.

[0012] Optionally, the ends of the two upper support arms away from the top seat are fixedly connected to a fixing seat by a pin, and the two fixing seats have through threaded holes inside.

[0013] Optionally, a lead screw is threaded into the inner end of the threaded hole, and the lead screw passes through two fixed seats, with a motor fixedly connected to one end of the lead screw.

[0014] Optionally, an anti-slip pad is fixedly connected to the bottom of the base, and side connecting plates are fixedly connected to both ends of the base.

[0015] Optionally, a side mounting plate is rotatably connected to the end of the side connecting plate away from the base, and a double-stage telescopic arm is rotatably connected to the top of the side mounting plate via a pin. The end of the double-stage telescopic arm away from the side mounting plate is rotatably connected to the top seat via a pin.

[0016] This utility model has the following advantages and beneficial effects:

[0017] 1. Multi-angle adjustment: Through the rotational connection between the rotating shaft and the worktable, and the guiding sliding of the sliding ball in the annular groove, the 360-degree rotation function of the worktable is realized. Combined with the precision meshing structure of the V-shaped positioning teeth and V-shaped positioning groove, the worktable can be precisely positioned and locked at every 5-degree angle. This multi-angle adjustment design allows maintenance personnel to adjust the chemical equipment to the optimal operating angle, avoids poor working postures during maintenance, improves operating accuracy and work efficiency, and adapts to various complex maintenance conditions.

[0018] 2. Secure Locking: The locking system, consisting of a locking nut, locking sleeve, and return spring, combined with the V-shaped self-centering structure of the positioning teeth and positioning groove, ensures the stability of the worktable in the locked state. The wedge effect of the V-shaped structure enhances the locking force and prevents angular deviation caused by vibration. The cooperative design of the guide groove and guide bar ensures the smooth sliding of the locking sleeve and the positioning accuracy. This multi-protection mechanism significantly improves the safety and reliability of chemical equipment maintenance.

[0019] 3. High-efficiency and stable lifting: Through the scissor lift structure design and electric drive, a smooth and reliable height adjustment function is achieved. The lead screw adopts a symmetrical design of left and right helical threads to ensure synchronous uniformity during the lifting process, avoiding uneven load and jamming. The motor drive system greatly reduces the labor intensity of operators, making height adjustment more precise and efficient. The lifting range is wide to meet the maintenance needs of different heights, thereby improving the flexibility of maintenance operations. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0034] like Figures 1-2 As shown, the present invention provides a support device for the maintenance of chemical equipment, including a lifting device and a rotating mechanism. This device can meet the multi-angle and multi-height support requirements during the maintenance of chemical equipment, thereby improving the safety and efficiency of the maintenance work.

[0035] like Figures 3-5As shown, the rotating mechanism is located above the lifting mechanism. The rotating mechanism includes a connecting plate 1, with a rotating shaft 2 fixedly connected to the top of the connecting plate 1. A worktable 3 is rotatably connected to the top of the rotating shaft 2. Multiple auxiliary rods 4 arranged in a circumferential array are fixedly connected to the bottom of the worktable 3. Each of the auxiliary rods 4 has a sliding ball 5 fixedly connected to its bottom. An annular groove 6 nested with the sliding ball 5 is provided on the upper surface of the connecting plate 1. When this device is working, the lifting mechanism first adjusts the rotating mechanism to a suitable height, and then the worktable 3 is manually rotated to the required angle to meet the maintenance operation requirements at different angles. When the worktable 3 rotates, the sliding ball 5 slides in the annular groove 6, which plays a guiding and supporting role, ensuring that the worktable 3 rotates smoothly. The outer end of the auxiliary rod 4 is provided with a locking mechanism to fix the position of the worktable 3 at different angles, preventing the worktable 3 from rotating excessively and causing equipment damage or safety accidents.

[0036] like Figures 4-7 As shown, the locking mechanism includes a locking nut 7 threadedly connected to the outer wall of the auxiliary rod 4. A locking sleeve 8 is slidably connected to the outer wall end of the auxiliary rod 4, with the top end of the locking sleeve 8 contacting the locking nut 7. Multiple symmetrically arranged positioning teeth 9 are fixed to the bottom end of the locking sleeve 8. The positioning teeth 9 adopt a V-shaped structure design. A retaining ring 10 is fixedly connected to the outer end of the auxiliary rod 4, and a return spring 11 is slidably connected to the outer end of the auxiliary rod 4. The end of the return spring 11 near the retaining ring 10 abuts against the retaining ring 10, and the end away from the retaining ring 10 abuts against the locking sleeve 8. This elastic return structure ensures convenient and reliable operation. Multiple positioning grooves 12 matching the positioning teeth 9 are provided on the upper surface of the connecting plate 1. The positioning grooves 12 are V-shaped grooves, forming a precise fit with the V-shaped positioning teeth 9, effectively preventing lateral displacement and enhancing the locking effect. The multiple positioning teeth 9 are spaced 5 degrees apart, allowing for adjustment according to the required rotation angle. The worktable 3 is precisely rotated. When the rotation angle of the worktable 3 needs to be fixed, the locking nut 7 is manually tightened, causing the locking nut 7 to push the locking sleeve 8 downward, compressing the return spring 11. At the same time, the locking sleeve 8 pushes the positioning tooth 9 to engage with the positioning groove 12, achieving angle locking. This V-shaped interlocking structure transmits force evenly, avoiding local stress concentration. When the angle of the worktable 3 needs to be adjusted, the locking nut 7 is manually rotated in the opposite direction. The locking sleeve 8 moves upward under the action of the return spring 11, and the locking sleeve 8 drives the positioning tooth 9 to disengage from the positioning groove 12, allowing the worktable 3 to rotate freely. This V-shaped meshing design not only ensures the flexibility of angle adjustment and the reliability of locking, but also effectively prevents angle deviation caused by vibration during operation through the self-centering cooperation of the V-shaped positioning tooth and the V-shaped positioning groove. At the same time, the wedge effect of the V-shaped structure enhances the locking force and improves the stability of the overall structure.

[0037] like Figures 7-8As shown, in order to improve the stability of the sliding of the locking sleeve 8, the inner wall of the locking sleeve 8 is provided with a plurality of symmetrically arranged guide grooves 13. The outer end of the retaining ring 10 is fixedly connected with a plurality of guide strips 14 that match the guide grooves 13. The guide grooves 13 slide on the guide strips 14 to prevent the locking sleeve 8 from rotating and shifting when the angle is locked, and to ensure that the positioning teeth 9 can be accurately aligned with the positioning grooves 12.

[0038] like Figure 1 As shown, the lifting device includes a base 15, which is rotatably connected to two symmetrically arranged lower support arms 16 via pins. Each of the two lower support arms 16 is hinged to an upper support arm 17 at the end away from the base 15. The end of the upper support arm 17 away from the lower support arms 16 is rotatably connected to a top seat 18 via a pin. The top of the top seat 18 is fixedly connected to the connecting plate 1. This scissor-type structure design gives the lifting device a large lifting range and a high load-bearing capacity.

[0039] like Figure 1 and Figures 9-11 As shown, the ends of the two upper support arms 17 away from the top seat 18 are fixedly connected to fixed seats 19 by pins. The interior of the two fixed seats 19 has through threaded holes, and the inner end of the threaded holes is threaded with a lead screw 20, which passes through the two fixed seats 19. One end of the lead screw 20 is fixedly connected to a motor 21, and the output shaft of the motor 21 is fixedly connected to the lead screw 20. The motor 21 drives the lead screw 20 to rotate, and the mounting bracket of the motor 21 is fixedly connected to the fixed seats 19. By adjusting the distance between the two fixed seats 19 through the threaded engagement between the lead screw 20 and the fixed seats 19, the height of the lifting device can be adjusted. This electric lifting method reduces the labor intensity of the operator and improves the adjustment accuracy.

[0040] To improve the stability of the support device, such as Figure 8 As shown, an anti-slip pad 22 is fixedly connected to the bottom of the base 15. The anti-slip pad 22 is made of rubber material with a high coefficient of friction, which effectively prevents the device from sliding during use. Side connecting plates 23 are fixedly connected to both ends of the base 15. A side mounting plate 24 is rotatably connected to the end of the side connecting plate 23 away from the base 15. A double-stage telescopic arm 25 is rotatably connected to the top of the side mounting plate 24 through a pin. The end of the double-stage telescopic arm 25 away from the side mounting plate 24 is rotatably connected to the top seat 18 through a pin. The double-stage telescopic arm 25 includes a first-stage telescopic arm and a second-stage telescopic arm. The first-stage telescopic arm can make linear reciprocating motion along the extension direction of the second-stage telescopic arm. By adjusting the length of the second-stage telescopic arm, the stability and adjustability of the entire support device can be further enhanced. At the same time, the bottom of the side mounting plate 24 is also provided with the same anti-slip pad 22, which further improves the anti-slip performance of the device and ensures the safe conduct of maintenance work.

[0041] When using this device, first move the entire device to a suitable position, ensuring that the anti-slip pad 22 at the bottom of the base 15 is in close contact with the ground to prevent slippage during use. Based on the maintenance requirements of the chemical equipment, the operator first starts the motor 21 to drive the lead screw 20 to rotate. The two ends of the lead screw 20 have opposite thread directions. When the motor 21 drives the lead screw 20 to rotate clockwise, the two fixed seats 19 move closer together, reducing the angle between the two upper support arms 17 and the two lower support arms 16, gradually closing them. The two upper support arms 17 then drive the top seat 18 to rise, achieving the desired elevation. When the motor 21 drives the lead screw 20 to rotate counterclockwise, the two fixed seats 19 move further apart, increasing the angle between the two upper support arms 17 and the two lower support arms 16. As the lifting device gradually unfolds, the two upper support arms 17 drive the top seat 18 to descend, achieving the purpose of lowering and thus realizing precise height adjustment. This symmetrical reverse thread structure not only improves the stability of lifting but also prevents uneven loading during the lifting process, ensuring that the device can be adjusted synchronously and evenly. Operators can precisely control the start, stop, and rotation direction of the motor 21 according to the maintenance height requirements, adjust the lifting device to an appropriate height, and then rotate the worktable 3 to the required angle according to the maintenance needs. The position of the worktable 3 is fixed by the locking mechanism, and finally the chemical equipment is placed on the worktable 3 for maintenance. The whole process is simple to operate, flexible to adjust, safe and reliable. The bidirectional thread design effectively prevents the occurrence of lifting imbalance and jamming, improving the service life and safety factor of the device.

[0042] The surface of the workbench 3 can be equipped with anti-slip rubber pads to increase the friction coefficient with the contact surface of the chemical equipment and prevent the equipment from sliding. The workbench 3 can also be equipped with detachable guardrails to prevent the equipment from accidentally slipping. The motor 21 can be equipped with an overload protection device to prevent safety accidents caused by malfunctions during lifting. At the same time, the key connections of the entire support device are made of high-strength materials to ensure sufficient load-bearing capacity and service life.

[0043] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
