Abstract
The utility model relates to a hydraulic rock drill for opencast mining, quarries, tunnel project construction and the like, in particular to a wire threaded insert structure which can lock a threadedconnecting component tightly inside a screw hole so that the threaded connecting component can not release in intensive vibrating and shocking environment. A to-be-connected component I and a to-be-connected component II are connected via the threaded connecting component, a wire threaded insert is fixedly installed inside a screwed hole on the to-be-connected component II, and the threaded connecting component is connected with the wire threaded insert. The wire threaded insert structure has the advantages of effectively enhancing fatigue strength of threaded connection of the to-be-connected components, preventing screws from releasing and avoiding detachment failure caused by the screwed hole clogged by rust.
Description
Technical field
The utility model relates to a kind of hydraulic gate that is used for surface mining, quarry and tunnel construction etc., particularly a kind ofly in strong vibrations and shock environment, threaded connector can be lock onto in the screw, not the hydraulic gate that can get loose steel-wire screw-socket structure.
Background technology
The manufacturing technology of external hydraulic gate is quite ripe, as the Atlas-Copco company of Sweden, Sandvik company, Finland Tamrock company etc. all is to be devoted to hydraulic gate technical research and popularization always, and its technical level is represented the advanced level of the world today.Development at China's hydraulic gate is started late, last century the eighties, from some types or the technology of external introduction, successively cooperate production hydraulic gate and drill carriage thereof with the Atlas-Copco company of Sweden as Nanjing Engineering Machinery Plant, Shenyang Pneumatic Tools Factory, Tianshui Pneumatic Tools Plant.Xuanhua mining machinery factory, Shenyang nonferrous metallurgical equipment head factory, Lianhua Shan Mountain metallurgical machinery factory successively cooperates production hydraulic gate and drill carriage thereof with French Secoma company.Owing to be subjected to the restriction of aspect conditions such as raw material, technology, equipment and technology at that time, after product creates, still had a certain distance with international most advanced level.More distinct issues are that the stability of properties of product and reliability aspect remain further to be improved.Hydraulic gate when work vibrations are very violent, and the screw that connects each part is easy to become flexible, and brings very big unsafe factor to machine works, and reason mainly is to have adopted the regular screw threads syndeton on the helicitic texture more, and locking property is guarantee not.
Summary of the invention
The purpose of this utility model is exactly in order to solve the weak point in the background technology, to provide a kind of and prevent that effectively screw from getting loose, hydraulic gate simple in structure steel-wire screw-socket structure.
To achieve these goals, the utility model hydraulic gate steel-wire screw-socket structure, connect by threaded connector between connected piece I and the connected piece II, be installed with steel-wire screw-socket in the connected piece II upper screwed hole, threaded connector is connected with steel-wire screw-socket.
For of the present utility model a kind of preferred, threaded connector comprises bolt and screw.
The utility model is compared with background technology, has the fatigue strength that effective raising connected piece is threaded, and prevents that screw from getting loose, and has avoided extremely can't dismantling because of the screwed hole rust.
The utility model is elaborated with reference to accompanying drawing below in conjunction with embodiment.
Description of drawings
Fig. 1 is the structural representation of hydraulic gate with the steel-wire screw-socket structure.
The specific embodiment
Embodiment 1: with reference to Fig. 1.Hydraulic gate steel-wire screw-socket structure connects by threaded connector 5 between connected piece I 4 and the connected piece II 1, is installed with steel-wire screw-socket 3 in connected piece II 1 upper screwed hole 2, and threaded connector 5 is connected with steel-wire screw-socket 3.Threaded connector 5 comprises bolt and screw.
Embodiment 2: with reference to Fig. 1.Steel-wire screw-socket (abbreviation silk braid) is the insert that develops for protection non-ferrous metal screwed hole, screws in and is fastened in the screwed hole of connected piece II 1, forms standard female, and threaded connector 5 is screwed into wherein again.Use indicates the steel-wire screw-socket special screw tap tapping of regulation screw thread specification, process screwed hole 2, erector is installed into steel-wire screw-socket 3 in the screwed hole 2 by hand, steel-wire screw-socket 3 diameters under the free state are bigger slightly than its screwed hole of packing into 2 diameters, thereby make steel-wire screw-socket 3 be subjected to special spanner torsion that its diameter is diminished during assembling, enter and attack in the screwed hole 2 of silk with special screw tap, after installing, steel-wire screw-socket 3 produces the effect that spring-like expands, make its firm being fixed in the screwed hole 2, and back-outing and bring out with threaded connector 5 never, during installation threaded connector 5 is screwed in the steel-wire screw-socket 3, forming elasticity between threaded connector 5 and the screwed hole 2 that steel-wire screw-socket 3 is installed is connected, thereby spiral shell square and half of thread angle error between the internal and external threads have been eliminated, can on the length of regulation, make evenly distribution of load on every circle screw thread, thereby strengthened internal thread, therefore can improve the fatigue strength that part is threaded, prevent that threaded connector 5 from getting loose, make the threaded connector 5 of various materials be in best user mode.Steel-wire screw-socket 3 can be locked at threaded connector 5 in the screwed hole 2, when being shaken and impact, threaded connector 5 unlikely releasing is come off, and is better than common locking device processing performance.
What need understand is: though the foregoing description is to the utility model detailed explanation of contrasting; but these explanations; just to simple declaration of the present utility model; rather than to restriction of the present utility model; any utility model that does not exceed in the utility model connotation is created, and all falls in the protection domain of the present utility model.
