Description

Technical Field

[0001] This utility model relates to the field of wine cellar maintenance technology, and in particular to a device for reinforcing and maintaining wine cellars. Background Technology

[0002] The storage caverns for baijiu (Chinese liquor) are in a humid and enclosed environment for a long time, and the surface of their concrete lining structure is susceptible to chemical erosion and physical weathering. As the years of use accumulate, the lining structure gradually ages and falls off, and the overall stability is significantly reduced. It is necessary to reinforce it by adding steel structures weighing about 200 kg each at intervals of 3 meters.

[0003] Currently, construction often utilizes lifting platforms to assist in high-altitude operations. For example, Chinese utility model patent CN214527986U discloses a construction hoist with a movable platform, including a movable base, a lifting mechanism, and a platform. The movable base has multiple wheels at its bottom, the lifting mechanism is located above the movable base, and the platform is located above the lifting mechanism. Two symmetrically distributed lifting cylinders are located between the movable base and the platform, both inside the lifting mechanism. These cylinders drive the platform to move vertically, facilitating access for operators to the high work surface. However, this type of equipment has significant limitations:

[0004] 1. No dedicated load-bearing mechanism: The platform is only designed for personnel to stand on, and no heavy steel structure fixing device is set up. When installing the steel structure, multiple workers need to carry the steel structure on their shoulders and rely on manual lifting and positioning for installation, which is extremely labor-intensive and poses safety risks.

[0005] 2. Low material replenishment efficiency: When steel structures need to be replenished, the entire platform must be lowered to the ground, then the steel structures must be manually moved, and the platform must be raised again. Each replenishment requires repeated lifting and lowering operations, which is cumbersome, time-consuming, and labor-intensive, and seriously restricts construction efficiency. Utility Model Content

[0006] To address the technical problems of high labor intensity and low construction efficiency in existing technologies, this utility model provides a device for reinforcing and repairing wine storage caves.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A device for reinforcing and repairing wine cellars includes a base, an operating platform, and a lifting mechanism. The base is equipped with casters at its bottom, the operating platform is located above the base, and the lifting mechanism connects the base and the operating platform. It also includes a support frame and at least one set of load-bearing components, which include:

[0009] The column is vertically mounted on the base, and a vertical groove is provided on the side of the column;

[0010] Supports are fixedly installed at both ends along the length of the slide groove;

[0011] The screw is located inside the slide groove, and its length direction is parallel to the length direction of the slide groove. Both ends of the screw are rotatably connected to the support and the screw is axially fixed.

[0012] The motor's output end is connected to one end of the screw for driving;

[0013] The slider slides in conjunction with the groove, and is fitted onto the screw and threaded into the screw.

[0014] The support frame is fixedly connected to the slider. When the motor drives the screw to rotate, it drives the slider to move vertically along the slide groove, thereby driving the support frame to rise and fall.

[0015] Furthermore, the support at the top of the slide has a clearance hole, the first end of the screw passes through the clearance hole, a limit block is fixed to the first end of the screw, the limit block contacts the top surface of the support, the motor is located at the bottom of the slide, and the output end of the motor is driven by the second end of the screw.

[0016] Furthermore, there are two sets of load-bearing components, which are arranged side by side with intervals. The support frame includes a connecting rod and two support rods arranged side by side with intervals. The support rods are horizontally arranged, with one support rod corresponding to one set of load-bearing components. One end of the support rod is fixedly connected to the slider of the corresponding load-bearing component. The two ends of the support rod are respectively provided with upwardly extending limiting protrusions. Adjacent support rods are fixedly connected by a connecting rod.

[0017] Furthermore, the lifting mechanism is a hydraulically controlled lifting mechanism.

[0018] Furthermore, the operating platform is surrounded by an openable and closable fence structure, which has fall arrestor attachments for safety belts.

[0019] Furthermore, the fence structure consists of multiple vertical and horizontal bars welded together to form a grid-like frame. The horizontal and vertical bars of the grid-like frame constitute the fall arrestor attachment points, which can be used to attach safety belts.

[0020] Furthermore, the fence structure is equipped with hook-and-loop fasteners.

[0021] Furthermore, a safety gate is provided on the side of the fence structure, and the safety gate is rotatably connected to the fence structure.

[0022] Furthermore, the side of the operating platform is equipped with steps that allow operators to climb.

[0023] Furthermore, the mobile wheel set is equipped with a foot brake.

[0024] The beneficial effects of this utility model are:

[0025] This utility model addresses the technical challenges of high labor intensity and low work efficiency in the reinforcement construction of wine cellars by installing a load-bearing component (including a column, screw, support, motor, and slider) on the base for lifting the steel structure, and setting up a support frame for placing the steel structure, thereby separating the personnel lifting and steel structure lifting processes.

[0026] Personnel lifting and material lifting are independent. The support frame directly supports the steel structure, eliminating the need for traditional manual carrying and lifting. A motor-driven screw moves the slider up and down, enabling independent lifting of the support frame. When the operating platform is suspended at height, the support frame can be lowered to the ground to load the supply steel structure, avoiding repeated lifting and lowering of the operating platform and the associated energy consumption, time delays, and personnel lifting risks. Compared to the traditional method (which requires lowering the operating platform first, having workers lift the steel structure into the operating platform, and then raising the platform again), this invention significantly improves supply efficiency and drastically reduces labor intensity.

[0027] The horizontal support rods and the limiting protrusions at the ends of the support frame form a U-shaped support area for placing the steel structure. After the steel structure is placed, the limiting protrusions provide bidirectional restraint, effectively preventing the steel structure from shifting or falling during operation.

[0028] The operating platform is equipped with an openable and closable fence structure. The horizontal and vertical bars of the fence structure form a fall arrestor attachment point, ensuring that the safety belt is properly secured when working at height. Combined with the mobile wheel group brake, it establishes a two-level protection at height and on the ground, significantly reducing the risk of falling. Attached Figure Description

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the present invention will be further described below with reference to the accompanying drawings.

The described embodiments are only some of the embodiments of this application, and not a limitation of this utility model.

[0035] Reference Figure 1 and Figure 2 This utility model provides a device for reinforcing and repairing wine storage caves.

[0036] When reinforcing a wine cellar, the process is as follows: The steel structure is placed on the support frame 5, and the device is moved within the wine cellar using the moving wheel set 4. Upon reaching the area below the point to be reinforced, the moving wheel set 4 is braked, and the lifting mechanism 3 is lowered to its lowest position. Maintenance personnel, wearing five-point safety harnesses, climb onto the operating platform 2 and close the safety door 15. The safety rope is then secured to the fall arrestor on the fence structure 14, achieving a high-hanging, low-use design. Another operator manipulates the operating lever 13 to slowly raise the device via the lifting mechanism 3. Once the operating platform 2 reaches the designated height, the operator operates the controller (not shown). The controller (not shown) can be installed on the fence structure 14 or held by the operator. The controller (not shown) is used to control the forward rotation, reverse rotation, start and stop of the motor 10. When the motor 10 is started to rotate forward, it drives the screw 9 to rotate, which in turn drives the slider 11 and the support frame 5 to rise along the slide 7. When the steel structure reaches the designated installation height, the motor 10 stops working, and the steel structure is welded and fixed to the position to be reinforced on the wall of the wine cellar, thus completing the movement, lifting and installation of the steel structure.

[0037] If additional steel structures are needed midway, simply operate motor 10 to rotate in the reverse direction, and support frame 5 will descend to its lowest point. Place the steel structure on support frame 5, then operate motor 10 to rotate in the forward direction, and support frame 5 will carry the steel structure upward to the designated height. When supplementing steel structures, the operating platform is suspended at the working height, and support frame 5 can be lowered to the ground to load the supplemented steel structure, avoiding repeated raising and lowering of operating platform 2 and the associated energy consumption, time delays, and personnel raising and lowering risks.

[0038] After completing the work, adjust the lifting mechanism 3 and the load-bearing components to lower the operating platform 2 and the support frame 5 to a safe height (e.g., 0.2m above the ground). The safety door 15 should be closed throughout the entire operation to ensure the safety of maintenance personnel. Relying on the transfer of the mobile wheel set 4, the device can be moved to the next location and the above steps can be repeated.

[0039] In addition to the aforementioned reinforcement function, this device can also be used for the maintenance of various components inside the wine cellar, such as ventilation systems, temperature and humidity measurement systems, cameras, lighting, fire sprinklers, and warning signs. The process is as follows: The device is moved within the wine cellar by the movable wheel set 4. Upon reaching the area below the maintenance point, the movable wheel set 4 is braked, lowering the lifting mechanism 3 to its lowest position. Maintenance personnel, wearing a five-point safety harness, climb onto the operating platform 2 and close the safety door 15. The safety rope is then secured to the fall arrestor on the fence structure 14, achieving a high-hanging, low-use design. Another operator manipulates the operating lever 13 to slowly raise the operating platform 2 via the lifting mechanism 3 to the designated height. Maintenance personnel can then inspect the components requiring repair. After completing the inspection, the lifting mechanism 3 is adjusted to lower the operating platform 2 to a safe height (e.g., 0.2m above the ground). Throughout the entire process, the safety door 15 must be closed to ensure the safety of the maintenance personnel.

[0040] like Figure 1 and Figure 2 As shown, in some embodiments, the device for reinforcing and repairing wine cellars includes a base 1, an operating platform 2, and a lifting mechanism 3. The bottom of the base 1 is provided with a set of movable wheels 4. The set of movable wheels 4 can be made entirely of omnidirectional wheels, or the front of the base 1 can be made of omnidirectional wheels and the rear of the base 1 can be made of ordinary rollers. Preferably, the set of movable wheels 4 is equipped with a foot brake (not shown) to facilitate locking when the device reaches the designated position and prevent shaking during operation. In addition, bricks or wooden blocks can be used to brace the set of movable wheels 4.

[0041] The operating platform 2 is located above the base 1. For the safety of the operators, a fence structure 14 is set around the operating platform 2. The fence structure 14 can be welded together from ordinary steel pipes, or it can be spliced ​​together from steel pipes and wooden boards. The fence structure 14 can have a safety door 15 on its side. The safety door 15 can be made of ordinary wooden boards or a steel pipe frame. The fence structure 14 is equipped with a fall arrestor for attaching safety belts. The fall arrestor can be bolted or welded to the fence structure 14 with a hanging ring (not shown) for attaching the safety belt; or it can be directly made of the steel pipe of the fence structure 14, and the safety belt buckle can be directly attached to the steel pipe.

[0042] The lifting mechanism 3 is connected between the base 1 and the operating platform 2, and also includes a support frame 5 and at least one set of load-bearing components, the load-bearing components including:

[0043] The column 6 is vertically mounted on the base 1. The side of the column 6 has a vertically opened sliding groove 7. The length of the column 6 corresponds to the maximum lifting height of the support frame 5. The design should be reasonable according to the actual working conditions so that the steel structure can be raised to the area to be reinforced in the wine cellar. The lifting height of the operating platform 2 should be such that the operator standing in the operating platform 2 can touch the steel structure on the support frame 5 and weld the steel structure to the area to be reinforced in the wine cellar. Therefore, the lifting height of the support frame 5 and the operating platform 2 should be adaptively adjusted according to the actual working conditions.

[0044] Supports 8 are fixedly installed at both ends along the length of the slide groove 7;

[0045] The screw 9 is located inside the slide groove 7, with its length parallel to that of the slide groove 7. Both ends of the screw 9 are rotatably connected to the support 8, and the screw 9 is axially fixed. While the screw 9 is rotatably connected to the support 8 and axially fixed, it is not threaded. It is sufficient that the screw 9 can rotate around a vertical line without moving vertically. To support the weight of the steel structure, a limiting block 12 can be welded to one end of the screw 9. The limiting block 12 abuts against the support 8 and bears the weight. However, this increases the friction between the limiting block 12 and the support 8. This problem can be overcome by adjusting the roughness of the two contact surfaces and the power of the motor 10. Preferably, the support 8 at the top of the slide 7 has a clearance hole, the first end of the screw 9 passes through the clearance hole, the first end of the screw 9 is fixed with a limit block 12, the limit block 12 contacts the top surface of the support 8, the motor 10 is located at the bottom of the slide 7, the output end of the motor 10 is driven connected to the second end of the screw 9, and the vertical projection of the outer contour of the limit block 12 is at least partially outside the outer contour of the clearance hole, which is used to support the weight of the steel structure and the support frame 5, and to avoid the weight of the steel structure being transmitted to the motor 10 at the bottom by the screw 9 as much as possible;

[0046] Motor 10, the output end of motor 10 is driven to one end of screw 9. Motor 10 can be located at the top or bottom of slide groove 7. For the drive connection, it can be welded and fixed for transmission, or it can be connected by a coupling, or a gear can be set at the output end of motor 10 and a gear can also be set at the second end of screw 9, and the two gears mesh to perform gear transmission.

[0047] The slider 11 is slidably engaged with the slide groove 7. The slider 11 is sleeved on the screw 9 and threadedly engaged with the screw 9. The slider 11 and the slide groove 7 can be in direct contact and sliding engagement or indirect contact and sliding engagement. When the slider 11 is in direct contact with the slide groove 7, one plane of the slider 11 can be in sliding contact with the inner wall of the slide groove 7, or multiple planes can be in sliding contact with the inner wall of the slide groove 7. The purpose is to prevent the slider 11 from rotating and to allow it to move up and down along the slide groove 7.

[0048] The support frame 5 is fixedly connected to the slider 11. When the motor 10 drives the screw 9 to rotate, it drives the slider 11 to move vertically along the slide groove 7, thereby driving the support frame 5 to rise and fall. The support frame 5 can be a known carrier for placing items, and its specific structure is not particularly limited here, as long as it can hold a steel structure. In addition, additional fixing structures, such as clamps, binding ropes, or limiting structures, can be set to fix the steel structure to the support frame 5.

[0049] The lifting mechanism 3 is connected between the base 1 and the operating platform 2. The lifting mechanism 3 includes a fixed part and a telescopic part. The fixed part is fixedly connected to the base 1 (e.g., by welding or bolting), and the telescopic part is fixedly connected to the operating platform 2 (e.g., by welding or bolting). The lifting mechanism 3 is an existing mechanism in the relevant technical field, such as a lifting cylinder or a lifting hydraulic cylinder. The specific structure will not be described in detail here. The hydraulically controlled lifting mechanism 3 is preferred, but an electric or other energy-controlled lifting mechanism 3 can also be used.

[0050] like Figure 1 and Figure 2 As shown, in some embodiments, there are two sets of load-bearing components, which are arranged side by side with intervals. The support frame 5 includes a connecting rod 51 and two support rods 52 arranged side by side with intervals. The support rods 52 are arranged horizontally, and one support rod 52 corresponds to one set of load-bearing components. One end of the support rod 52 is fixedly connected to the slider 11 of the corresponding load-bearing component. The two ends of the support rod 52 are respectively provided with upwardly extending limiting protrusions 53. Two adjacent support rods 52 are fixedly connected by the connecting rod 51. This embodiment preferably uses two sets of load-bearing components to ensure stability and reduce manufacturing costs. The support frame 5 includes a connecting rod 51 and two parallel, spaced-apart support rods 52. The support rods 52 are horizontally positioned, with one support rod 52 corresponding to one set of load-bearing components. One end of the support rod 52 is fixedly connected to the slider 11 of the corresponding load-bearing component, thus forming a high-strength steel structure load-bearing structure. The horizontal support rods 52 and the limiting protrusions 53 at their ends of the support frame 5 form a U-shaped support area for placing the steel structure. After the steel structure is placed, the limiting protrusions 53 provide bidirectional constraint, effectively preventing the steel structure from shifting or falling during operation. Other fasteners, such as clamps, ropes, or holding devices, can also be used to fix the steel structure to the support rods 52. To further increase the structural strength of the load-bearing components, two adjacent support rods 52 are fixedly connected by the connecting rod 51 to improve overall stability. Welding is preferred, but bolt connection is also possible.

[0051] Furthermore, the lifting mechanism 3 is a hydraulically controlled lifting mechanism 3. The lifting mechanism 3 is an existing mechanism in the relevant technical field, and the specific structure will not be described in detail here. It is preferred to use a hydraulically controlled lifting mechanism 3, but an electric or other energy-controlled lifting mechanism 3 can also be used.

[0052] like Figure 1 and Figure 2 As shown, in some embodiments, the fence structure 14 is formed by welding multiple vertical bars and multiple horizontal bars to form a grid-like frame. The horizontal and vertical bars of the grid-like frame constitute the anti-fall hook-up part, which can be used for safety belt hook-up. The fence structure 14 can be a rectangular frame or a frame of other shapes, which is not particularly limited here.

[0053] like Figure 1 and Figure 2 As shown, a safety door 15 is further provided on the side of the fence structure 14. The safety door 15 is rotatably connected to the fence structure 14. For the rotatable connection, a hinge or a pivot can be used for the rotatable connection.

[0054] like Figure 1 and Figure 2 As shown, the operating platform 2 is further provided with steps 16 on its side for the operator to climb.
