Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of maintenance construction, in particular to a split jack used in a production site. Background Art
[0002] Manufacturing companies, especially industrial manufacturing companies, often need to use jacks when producing or repairing construction sites. Jacks are used to move or support objects. Commonly used jacks are hydraulic and worm gear. The above two types of jacks are expensive and easy to damage, especially the worm gear jack. Since the outer shell of the jack is a cast iron part and the inner part is a worm gear mechanism, when subjected to a large external force, the outer shell of the worm gear jack is easy to crack or the worm gear mechanism is damaged and cannot be used any more.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0021] The purpose of the present utility model is to provide a split jack for use in a production site to solve the problems existing in the above-mentioned prior art. The structure is simple and easy to use.
[0022] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the drawings and specific embodiments.
[0023] The present utility model provides a split jack for use in a production site, as Figures 1 to 4 shown, comprising: a base 1 and a lifting screw 2. A threaded groove is provided in the middle of the base 1; the first end of the lifting screw 2 is used for threaded connection to the threaded groove, and the second end of the lifting screw 2 is used for extending out of the threaded groove and pressing against an item to be repaired. Rotating the base 1 can cause the lifting screw 2 to rise or fall so as to displace or support the item to be repaired.
[0024] In a preferred embodiment, the second end of the lifting screw 2 is a hexagonal nut structure 3, which has a simple structure and is convenient to cooperate with a wrench for use.
[0025] In a preferred embodiment, the split jack for use in a production site further comprises a plurality of handles 4. Each handle 4 is perpendicularly and fixedly connected to the outer side wall of the base 1, and the handles 4 are uniformly arranged along the circumferential direction of the base 1.
[0026] In a preferred embodiment, a support disc 5 is provided at the bottom of the base 1.
[0027] In a preferred embodiment, the split jack for use in a production site further comprises a locking snap ring 6. The locking snap ring 6 is provided with internal threads, and the locking snap ring 6 is used for threaded connection with the lifting bolt and is arranged above the base 1. It has a simple structure. After the lifting screw 2 is lifted or lowered to the use position, rotating the locking snap ring 6 to the top of the base 1 can further ensure the stability between the lifting screw 2 and the base 1.
[0028] In a preferred embodiment, the base 1, the lifting screw 2, the handles 4 and the locking snap ring 6 are all made of cast steel. Since cast steel has good plasticity and toughness and can bear greater external forces, it is not easy to break, has a long service life, a wide range of applications, and can be applicable to various harsh environments. At the same time, due to its simple structure, convenient production and low cost, it can reduce the production cost of enterprises.
[0029] In a preferred embodiment, the threads of the threaded groove and the lifting screw 2 are threads with an angle and pitch having a self-locking function, which further ensures the stability when the lifting screw 2 supports the base 1.
[0030] Specific examples are applied in the present utility model to expound the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
