Description

Technical Field

[0001] The utility model relates to the technical field of garbage recycling, in particular to a synchronous lifting mechanism for a landscape underground garbage station. Background Art

[0002] With the acceleration of the urbanization process, the generation amount of urban domestic garbage is increasing continuously, and the demand for garbage treatment facilities is also becoming increasingly urgent. Traditional garbage stations often have problems such as large floor area, unattractive appearance, and odor emission, which not only affect the overall image of the city but also have an adverse impact on the living environment of surrounding residents. In order to improve this situation, landscape underground garbage stations have emerged. Such garbage stations hide the garbage treatment facilities underground, and the ground part can be landscaped to integrate with the surrounding environment.

[0003] Most of the existing equipment has a relatively simple structure, which in turn makes the overall stability of the equipment relatively low. This may not only cause jams and failures during the lifting or compressing of the garbage station, prolong the garbage treatment time, and reduce the overall treatment efficiency, but also due to poor stability, the equipment needs to be repaired and maintained more frequently, including replacing damaged parts and repairing structural defects, which will undoubtedly increase the investment in manpower, material resources, and financial resources required for maintenance.

[0004] Therefore, there is an urgent need to provide a synchronous lifting mechanism for a landscape underground garbage station to solve the above problems. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the above-mentioned disadvantages of the prior art and provide a synchronous lifting mechanism for a landscape underground garbage station.

[0006] To solve the above technical problem, a technical solution adopted by the utility model is: to provide a synchronous lifting mechanism for a landscape underground garbage station, including an upper platform of the lifting mechanism. A plurality of lifting cylinders are installed at the bottom of the upper platform of the lifting mechanism. A mechanism fixed outer frame is fixedly connected between the bottoms of the plurality of lifting cylinders. The top of the mechanism fixed outer frame is fixedly connected with a lower base of a scissors frame auxiliary lifting mechanism. Two scissors frame outer support frames and a scissors frame inner support frame are installed at the top of the lower base of the scissors frame auxiliary lifting mechanism;

[0007] An upper base of the scissors frame auxiliary lifting mechanism is installed between the tops of the two scissors frame outer support frames and the scissors frame inner support frame. The top of the upper base of the scissors frame auxiliary lifting mechanism is fixedly connected with a lower platform of the lifting mechanism. The top of the lower platform of the lifting mechanism is fixedly connected with an outer frame box body;

[0008] Two lifting mechanism guide seats and sliding friction pairs are fixedly connected to the front and rear ends of the outer wall of the exoskeleton box, a plurality of lifting mechanism guide rails are fixedly connected between the bottom of the lifting mechanism upper platform and the top of the lifting mechanism lower platform, two synchronous electrical control units are installed on the plurality of lifting mechanism guide rails, and two scissor frame upper and lower base limit seats are fixedly connected to the top of the lower base of the scissor frame auxiliary lifting mechanism.

[0009] The utility model is further configured as follows: every two of the lifting mechanism guide seats and the sliding friction pairs, the lifting mechanism guide rails and the lifting oil cylinder are all located in a plane and are parallel to each other.

[0010] Through the above technical solution, the parallel layout can make the lifting mechanism guide seat and sliding friction pair, lifting mechanism guide rail and lifting cylinder bear uniform force during operation, reduce the deviation and instability caused by uneven force, thereby ensuring the accuracy and stability of the lifting action. The layout that is in the same plane and parallel to each other helps to disperse the load, so that the entire lifting mechanism can withstand greater weight and pressure, and improve the strength and reliability of the structure.

[0011] The utility model is further configured as follows: the plurality of lifting cylinders are customized with adjacent serial numbers from the same batch.

[0012] Through the above technical solution, lifting cylinders with adjacent serial numbers in the same batch have higher consistency in manufacturing process, material properties and dimensional accuracy, which enables them to move more coordinatedly when working and reduce the asynchrony or incoordination caused by individual differences in the cylinders, thereby improving the stability and reliability of the entire lifting system.

[0013] The utility model is further configured as follows: the tops and bottoms of the plurality of lifting mechanism guide rails are all integrated with the lifting mechanism upper platform and the mechanism fixing outer frame.

[0014] Through the above technical solution, the integrated structure eliminates possible weak points at the joints, allowing the entire lifting device to withstand greater loads and external forces, thereby improving the overall strength and stability of the structure, and being able to better resist vibration and impact, maintaining smooth operation during work and extending the service life of the equipment.

[0015] The utility model is further configured as follows: a plurality of the lifting mechanism guide seats and the inner walls of the sliding friction pairs are all slidably connected with lifting mechanism guide rails.

[0016] Through the above technical solution, the deflection and shaking of the lifting mechanism guide rail during operation can be effectively limited, making the lifting process smoother, reducing errors and potential safety hazards caused by instability, and providing precise guidance for the movement of the lifting mechanism guide rail to ensure that it moves along a predetermined straight line trajectory, thereby achieving accurate and stable lifting action.

[0017] The present utility model is further configured such that: one end of the outer support frame of the scissors frame is fixed to one end of the lower base of the scissors frame auxiliary lifting mechanism through a pin shaft.

[0018] Through the above technical solution, the pin shaft connection allows the outer support frame of the scissors frame to rotate flexibly relative to the lower base of the scissors frame auxiliary lifting mechanism, thereby adapting to various motion changes during the lifting process.

[0019] The present utility model is further configured such that: the other end of the outer support frame of the scissors frame is provided with rollers and placed inside the lower base of the scissors frame auxiliary lifting mechanism.

[0020] Through the above technical solution, the use of rollers reduces the friction coefficient between the outer support frame of the scissors frame and the lower base of the scissors frame auxiliary lifting mechanism, making the movement smoother, reducing energy loss, and the rolling of the rollers can provide a more accurate linear motion trajectory, which helps to ensure the accuracy and stability of the reciprocating motion of the outer support frame of the scissors frame.

[0021] The beneficial effects of the present utility model are as follows:

[0022] 1. By providing a lifting oil cylinder in the present utility model, when selecting materials, the lifting hydraulic cylinders with adjacent serial numbers in the same batch are customized, and the processing and manufacturing accuracy of the oil cylinders is used to ensure the telescopic synchronization of the oil cylinders themselves, so as to meet the synchronization of the lifting platform from the starting point;

[0023] 2. By providing an integrated structure in the present utility model, it can ensure the rigidity requirement of the platform and achieve the structural stability, and no rigid deformation will occur during the lifting process to affect the synchronization of the platform;

[0024] 3. By providing a scissors frame auxiliary lifting mechanism in the present utility model, a scissors frame auxiliary lifting mechanism is provided at the bottom of the lifting platform. Due to the structural characteristics of the scissors frame itself, the cross movement between the brackets and the linear movement of the fixed end and the rolling end are used to provide auxiliary support for the up and down movement of the lifting platform, ensuring the synchronization of the platform movement;

[0025] 4. By providing a synchronous electrical control unit in the present utility model, through real-time monitoring by the electrical control unit, the hydraulic system is adjusted in a timely manner to ensure the synchronization of the lifting oil cylinders from the source, so as to adjust the synchronization of the platform in a timely manner.
