Description

Technical Field

[0001] The utility model relates to the technical field of needle felt lifting, and specifically relates to a lifting device for needle felt base cloth production. Background Art

[0002] Needle felt base cloth is a base cloth made of woven fibers, which is usually used in the production of filter materials, thermal insulation materials, waterproof rolls, geotextiles and other products. Needle felt base cloth has good filtering and isolation effects, as well as good chemical corrosion resistance and aging resistance, so it is widely used in various industrial and environmental protection fields. In the subsequent production links of needle felt base cloth, according to actual application requirements, the needle felt base cloth is processed, such as coating, embossing, laminating, etc., to improve its performance and use. Since the needle felt base cloth has a certain weight, it will make the lifting operation more difficult, so the needle felt base cloth needs to be hoisted, and the needle felt base cloth lifting device will be pressed against the equipment entrance. Therefore, we propose a needle felt base cloth production lifting device to ensure the safety and smooth progress of the lifting process. Utility Model Content

[0005] Preferably, the lifting structure includes a hydraulic cylinder, the upper surface of the hydraulic cylinder is fixedly connected to the lower surface of the slider, the other end of the hydraulic cylinder is fixedly connected to a support plate, the lower surface of the support plate is symmetrically fixedly connected to a steel cable, and the inner ring wall of the steel cable is sleeved with a needle-punched felt base cloth.

[0006] Preferably, roller frames are symmetrically provided on the upper surface of the object supporting platform, and a semicircular groove is provided at the center of the upper surface of the roller frame.

[0007] Preferably, a ball is sleeved on the inner cavity of the slider, and the ball is clearance-matched with the slider, and the side wall of the ball is in contact with the upper surface of the slide rail.

[0008] Preferably, the number of the hydraulic cylinders is three and they are arranged in sequence.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: when lifting the needle felt base cloth, large and small frames are pre-set, and slide rails and sliders are arranged between the frames, which are then used by the lifting structure. The hydraulic cylinder is used as the main power for lifting and lowering, which can adapt to needle felt base cloths of different weights. The needle felt base cloth is moved by side sliding, and the length of the steel cable is controlled at the same time to avoid shaking due to excessive length during lifting, which can ensure the stability of the needle felt base cloth during lifting and moving. Only a small amount of manpower is needed for operation, and then it is placed on the surface of the object platform to complete the lifting and supporting work. At the same time, it is supported by the roller frame, which is convenient for the roller equipment to complete the subsequent processing of the needle felt. The operation can be completed quickly and accurately, and the work efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS
