Description

Technical Field

[0001] This utility model relates to the field of hydraulic support manufacturing technology, and in particular to a support column with a perforated cylinder bottom hoisting device. Background Technology

[0002] Hydraulic supports, as one of the key pieces of equipment in fully mechanized coal mining faces, directly affect the safety and efficiency of coal mining. The uprights, as crucial power support components of hydraulic supports, bear the important task of supporting the roof, thus requiring extremely high quality. During the manufacturing process of the upright cylinder body, the cylinder bottom and cylinder barrel typically need to be welded together on a welding machine. This process first requires clamping the cylinder barrel onto the welding machine, then lifting the cylinder bottom and accurately aligning it with the cylinder barrel. The traditional method for lifting the cylinder bottom involves temporarily welding lifting rings onto the outer circumference of the cylinder bottom to facilitate lifting the cylinder bottom to the designated position using cranes or other equipment. However, this method has significant drawbacks: firstly, each welding and subsequent grinding of the lifting rings not only increases operating time but also consumes substantial manpower and material resources; secondly, the quality of the welding directly affects the safety of the cylinder bottom lifting process, and improper welding may lead to accidents during lifting, threatening the safety of the operators.

[0003] Utility model patent CN219254594U discloses a high-efficiency tooling for lifting and positioning the bottom of a hydraulic cylinder. This solution mainly combines a cylinder bottom sleeve tooling for lifting the cylinder bottom with a chuck tooling for positioning and clamping the cylinder bottom, solving the problems of difficulty in horizontally placing the cylinder bottom and the inability of a three-jaw chuck to effectively clamp a flat cylinder bottom during traditional lifting processes. However, this tooling has certain limitations in practical applications. For example, the transition fit between the cylinder bottom sleeve pad and the inner hole of the cylinder bottom leads to varying friction during lifting, causing wear on the pad over time and increasing the maintenance cost of the tooling.

[0004] In view of the above problems, it is particularly necessary to develop a column cylinder bottom lifting device that requires no additional welding, can be quickly installed and disassembled, and is reusable. This utility model proposes a new solution to address these problems in the existing technology, aiming to improve production efficiency, reduce production costs, and ensure operational safety. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, this utility model designs a support column perforated cylinder bottom hoisting device that is structurally sound, easy to operate, and safe and reliable, solving the problems of low efficiency, high cost, and waste inherent in traditional hoisting methods. When hoisting the perforated cylinder bottom, the sliding body is first moved upwards, the lifting rod is inserted into the liquid passage hole and hooked onto the cylinder bottom, then the sliding body is moved downwards, the anti-detachment rod is inserted into the liquid passage hole, and the screws are tightened. The cylinder bottom can then be hoisted using an overhead crane or similar device. After the cylinder bottom is properly clamped, the screws are loosened, the sliding body is moved upwards out of the liquid passage hole, and then the lifting rod is removed from the air.

[0006] This utility model is achieved through the following technical solution: a support column with a perforated cylinder bottom hoisting device, characterized in that it includes a hoisting component and an anti-detachment component;

[0007] The lifting assembly includes a lifting ring and a lifting rod, with the lifting rod being threadedly connected to the lifting ring.

[0008] The anti-detachment component includes a locking screw, a sliding sleeve, and an anti-detachment rod. The sliding sleeve has internal threads, the locking screw is threadedly connected to the sliding sleeve, and the anti-detachment rod is aligned with the threaded hole on the sliding sleeve. The sliding sleeve drives the anti-detachment rod to move freely along the lifting rod through the locking screw.

[0009] Furthermore, a clamping component is provided between the sliding sleeve and the anti-detachment rod, and the clamping component is a locking screw, so that the sliding sleeve is in close contact with the rod.

[0010] Furthermore, the lower end of the boom is provided with a protrusion that matches the size of the fluid passage hole on the bottom of the cylinder.

[0011] Furthermore, the lifting ring is ring-shaped.

[0012] Furthermore, the upper part of the boom is provided with a positioning flange that can limit the maximum movement distance of the sliding sleeve.

[0013] Furthermore, the mating surface of the boom and the anti-detachment rod is provided with a guide groove, and the inside of the sliding sleeve is provided with a guide protrusion that matches the guide groove. Attached Figure Description
