Description

Technical Field

[0001] The utility model relates to the field of lifting platforms, in particular to a pneumatic lifting platform which can be controlled to start and stop at any time. Background Art

[0002] Currently, the primary building materials used in underground windbreak and airtight construction are typically bricks, cement, and sand. However, throughout the entire construction process, the lifting and lowering of these materials is almost entirely manual. This purely manual operation presents several serious problems. First, work efficiency is significantly reduced. Manual material handling is slow, and the amount of material that can be moved at any one time is limited, significantly hindering construction progress. Second, the workload is extremely high. Frequent material handling requires significant physical and mental effort. Materials like cement and sand are not only heavy but also easily scatter during handling, increasing the difficulty and workload of the operation. Prolonged periods of this intense work can easily lead to fatigue and exhaustion among employees. In view of the above-mentioned unfavorable conditions, it is necessary to develop a pneumatic lifting platform that can be controlled to start and stop at any time. The purpose is to change the backward situation in which the lifting of building materials in current construction relies entirely on manpower. By introducing advanced pneumatic technology, the labor efficiency of employees can be improved and the labor intensity of employees can be reduced, thereby promoting underground construction to develop in a more efficient, safe and humane direction. Utility Model Content

[0003] The purpose of this utility model is to provide a pneumatic lifting platform that can be controlled to start and stop at any time. Through pneumatic control, it can be started and stopped at any time, reducing human intervention, and through sliding and folding design, the platform occupies less space when not in use, and when in use, the storage space can be expanded as needed to promote underground construction to develop in a more efficient, safe and humane direction.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] A pneumatic lifting platform that can be controlled to start and stop at any time includes a base 1 with walking wheels 2 installed on the base. It is characterized in that telescopic cylinders 3 are installed at four sides of the base, and the telescopic ends of the telescopic cylinders are movably hinged with a platform table 4. The left and right sides of the platform table are respectively slidably matched with left and right bottom plates 5. The outer sides of the left and right bottom plates 5 are respectively provided with installation boxes 51 and storage racks 52, and the front and rear sides of the platform table are respectively hinged with side frames 6.

[0006] Telescopic cylinders 3 are fixedly installed at both ends of the bottom of the platform table, and connecting seats 53 are installed on the bottom surfaces of the ends of the left and right bottom plates 5. The telescopic ends of the telescopic cylinders are fixedly connected to the connecting seats 53.

[0007] The platform table top 4 and the side frame 6 are connected via snap fasteners.

[0008] The ends of the storage box 51 and the storage rack 52 are respectively movably connected with a latch 54, and the end of the side frame 6 is provided with a snap ring 61. When the latches 54 at the ends of the storage box 51 and the storage rack 52 are snapped into the snap ring 61 on the outer side of the side frame 6, the storage box 51, the storage rack 52, and the side frame 6 form a frame-shaped structure; after the side frame 6 is laid flat, the storage box 51 and the storage rack 52 slide outward and extend to form a platform support structure.

[0009] A slide groove is provided in the middle of the platform table top 4, and the bottoms of the left and right bottom plates are respectively inserted into the slide grooves and slide in cooperation with the slide grooves.

[0010] The storage rack 52 is a two-layer or three-layer rack.

[0011] There are three or four telescopic cylinders 3. When there are three telescopic cylinders 3, they are installed on the base in a triangle shape; when there are four telescopic cylinders 3, they are installed on the base in a rectangular shape.

[0012] The base 1 is fixed with a plurality of vertical telescopic cylinders 3, with the piston rod of each telescopic cylinder 3 pointing vertically upwards. The base 1 also includes a platform table 4, which is fixed on the piston rods of the four cylinders.

[0013] A plurality of vertical telescopic cylinders 3 are fixed on the base 1 and the starting signals are the same signal, and the cylinders can be started and stopped simultaneously through corresponding starters.

[0014] First, conduct a thorough inspection before use. Ensure that the running wheels 2 on the base 1 rotate flexibly, that the telescopic cylinder 3 is securely connected and the air path is unobstructed and leak-free, and that there are no jams in the sliding and hinged joints of components such as the platform top 4, left base plate 5, right base plate 5, side frame 6, storage box 51, and storage rack 52. Once ready, when the platform needs to be raised, a start signal is sent from the starter, and the multiple vertical telescopic cylinders 3 will operate simultaneously, extending the piston rods to push the platform top 4 upward. The operator can send a stop signal from the starter at any time according to actual needs to stop the telescopic cylinders 3, thereby precisely fixing the platform top 4 at the desired height. When placing items, arrange the positions appropriately according to the size and type of the items. Larger and heavier items should be placed on the platform top 4 first, while lighter tools or small items can be placed in the storage box 51 or storage rack 52. If the storage space of the platform needs to be expanded, the side frames 6 can be laid flat, and the telescopic cylinders 3 fixed at both ends of the bottom of the bottom platform can be used to push the connecting seats 53 installed on the bottom surfaces of the left and right bottom plates 5, thereby sliding the left and right bottom plates 5 outward and extending them, so that the storage boxes 51 and the storage racks 52 form the platform support structure, thereby increasing the storage area.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The automation level of lifting operations has been significantly improved. Through pneumatic control, it can be started and stopped at any time, reducing human intervention and greatly improving work efficiency.

[0017] It effectively reduces the labor intensity of employees and no longer relies on pure manpower to carry building materials. By adjusting the number and layout of telescopic cylinders and flexibly using the left and right bottom plates, storage boxes and shelves, it can meet the changes in different work scenarios and needs.

[0018] The sliding and folding design allows the platform to take up less space when not in use, while allowing for expanded storage space as needed when in use. The structure is relatively simple, the components are durable, and easy to inspect and repair, reducing maintenance costs and downtime during long-term use. BRIEF DESCRIPTION OF THE DRAWINGS
