Abstract
Description
Technical Field
[0001] This utility model relates to the field of fender production technology, and in particular to a fender production lifting device. Background Technology
[0002] Fenders are widely used as a buffer between ships and docks. They are produced by using metal or other materials as the core, covered with a layer of rubber, and then vulcanized or made into a roller-shaped product. Some fenders are large in size and long in length, and appropriate equipment is needed to support them when the rubber is wound during production. Otherwise, as the winding diameter increases, the weight of the rubber product also increases, which will cause the middle part of the core to bend gradually, affecting its service life and reducing the pass rate of the rubber product.
[0003] A search revealed that Chinese patent CN201921398079.2 discloses a lifting device for fender production. The device uses the extension and retraction of a hydraulic cylinder to drive a scissor fork mechanism, thereby achieving the up-and-down movement of the lifting support roller. The inclusion of sensors allows for easy adjustment of the lifting device's height according to actual production needs, making fender winding more convenient and faster, and greatly improving production efficiency. At the same time, the tension roller can adjust the tension of the lifting belt as needed.
[0004] The above-mentioned technical solution has the following drawbacks. Although such a lifting device can support the fender through a scissor fork structure to facilitate its processing and production, the fender itself is relatively heavy in actual use, and it is quite laborious to manually rotate the fender. In order to facilitate the support and rotation of the fender, a fender production lifting device is proposed. This device can easily lift the fender and rotate the cylindrical fender, thereby facilitating the wrapping of the protective structure on its outer wall, thus further improving the fender production efficiency. In addition, it is equipped with anti-fall components, which makes it safer when lifting the roller-type fender during production and processing.
[0005] In view of this, this work improves and solves the above problems. Through dedicated research and application of theoretical principles, a technical solution with a reasonable design that can effectively improve the above defects has finally been proposed.
[0006] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

It facilitates the lifting of fenders and the rotation of cylindrical fenders, thereby facilitating the wrapping of protective structures around their outer walls, which further improves the production efficiency of fenders. It is also equipped with anti-fall components, which provides better safety when lifting and processing roller-type fenders.
[0008] The solution to the above-mentioned technical problems of this utility model is as follows: A fender production lifting device includes a lifting bracket, a load-bearing bracket, and a fender lifting plate. A partition plate is fixedly installed on the lifting bracket. A load-bearing base is fixedly installed on the lifting bracket. Multiple hydraulic jacks are fixedly installed on the lifting bracket. Connecting members are fixedly connected to the multiple hydraulic jacks. Limiting sliders are fixedly connected to the connecting members. Limiting rods are fixedly installed on the inner wall of the lifting bracket. The limiting sliders are slidably connected to the limiting rods. Two sets of limiting rods are provided. A roller is rotatably connected to the lifting bracket. The ball screw is threadedly connected to a screw nut, which is fixedly connected to an anti-fall support plate. A brake disc is fixedly installed on the ball screw. A hydraulic brake is fixedly installed on the load-bearing base. A stepper motor is fixedly connected to the load-bearing base, and the drive end of the stepper motor is fixedly connected to the ball screw. A load-bearing bracket is fixedly connected to a limit slider and a fender lifting plate. The inner wall of the fender lifting plate is provided with a mounting groove, and the inner wall of the groove is evenly perforated with strip-shaped holes. Balls are evenly rotatably connected to the inner wall of the groove.
[0009] Based on the above technical solution, the present invention can be further improved as follows.
[0010] Furthermore, the limiting slider has a sliding hole that matches the limiting rod, and the inner wall of the sliding hole is slidably connected to the limiting rod.
[0011] Furthermore, the limiting slider is configured as a gate-shaped structure, and a through hole larger than the diameter of the ball screw is opened at the top center of the limiting slider.
[0012] Furthermore, the top of the fall arrestor support plate has a mounting hole larger than the diameter of the ball screw.
[0013] Furthermore, the top of the load-bearing base is provided with a rotating hole adapted to the ball screw, and the inner wall of the rotating hole is rotatably connected to the ball screw through a rotating shaft.
[0014] Furthermore, the partition plate has a strip-shaped hole adapted to the connector, and the connector passes through the strip-shaped hole and is fixedly connected to the limiting slider.
[0015] Furthermore, a protective box is fixedly connected to the outer wall of the stepper motor, and the stepper motor is fixedly connected to the bottom of the load-bearing base through the protective box.
[0016] Furthermore, the anti-fall support plates on both sides are configured as rectangular structures that fit the inner wall of the support bracket.
[0017] This utility model provides a fender production lifting device, which has the following advantages:

[0020] 3. After the cylindrical fender is raised to a suitable height, the stepper motor can be started to rotate the ball screw and drive the screw nut to slide on the inner wall of the support bracket. The anti-fall support plate at the top of the screw nut can support the limit slider. The hydraulic brake can be started to brake the brake disc, which can prevent the limit slider from driving the load-bearing bracket and the cylindrical fender at the top to fall when the multi-section hydraulic jack fails.
