Abstract
The utility model discloses a drill rod on a hydraulic crusher, which is characterized in that the utility model comprises a drill rod head and a drill rod, wherein the center of the drill rod head is provided with a groove or a screw which is horizontally provided with a pin hole. The shape of one end of the drill rod accords with that of the groove or the screw arranged on the drill rod head, and the end of the drill rod is horizontally likewise provided with a pin hole. The drill rod extends into the groove or the screw and is fastened with the groove or the screw through the respective pin holes and fixed pins in the pin holes. The drill rod is changed into the drill rod head and the drill rod, so that after the alteration, the drill rod can be free from the body model of a hydraulic crusher, and the aim of changing the length, the thickness and the shape of the drill rod can be achieved by directly changing the drill rod head rather than the drill rod, so that the utility model adapts the requirements of operating environment, and is particularly suitable for the working environment requiring changing the shape and the dimension of the drill rod at any time and at the time of protective dismantlement and breaking. The utility model can farthest improve the work efficiency of the crusher, simplify the fabrication models of the crusher, and reduce the manufacturing cost.
Description
Technical field
The utility model relates to percussion tool, the especially improvement of drill steel design on the hydraulic breaker.
Background technology
Hydraulic breaker is the bigger percussion tool of a kind of strength, now has been widely used in engineering construction fields such as building, road.Be provided with accumulator in the housing of hydraulic breaker, control guiding valve and have the vibration type piston of oil-filled inner chamber.Drill steel is connected with the lower end of piston.Pressure oil enters piston cavity through the control guiding valve after entering housing interior oil circuit and accumulator, and piston is subjected to the masterpiece ballistic motion, impacts the external work done of drill steel, and drill steel carries out crushing operation to broken object.Yet existing hydraulic breaker drill steel is monolithic construction, and whole pyramid, circle, globular model, wedge shape or the like are arranged.To different manipulating objects, need to select different drill steels, so at a working face, usually need to prepare various dissimilar drill steels, sometimes some drill steel can only match with the hydraulic breaker of certain specific model, so just need the hydraulic breaker of preparation different model, cause very big waste, also be not easy to field operation simultaneously.
Summary of the invention
The purpose of this utility model provides the drill steel on a kind of bipartial hydraulic breaker, so can not be subjected to the restriction of disintegrating machine body model, need not change drill steel and only needs directly to change drill head and can adapt to job requirements.
Drill steel on the said hydraulic breaker is made of drill head and drill steel two-section, drill head central authorities are provided with groove or silk hole, groove or silk hole laterally have a pin-and-hole, the shape in set groove or silk hole is consistent on the shape of drill steel one end and the drill head, this end drill steel transversely has a pin-and-hole equally, and drill steel extend into that the pin-and-hole by each other and the steady pin in the pin-and-hole are fastenedly connected in groove or the silk hole.
Owing to change drill steel into drill head and drill steel two parts, so after such transformation, drill steel will not be subjected to the restriction of hydraulic breaker body model, thereby need not change drill steel and directly change drill head and just can reach and change the requirement that drill steel length, thickness, shape adapt to operating environment.Need change the needs of the working environment of drill steel shape, size when being particularly suitable for protectiveness dismounting, fragmentation at any time, can improve the operating efficiency of disintegrating machine to greatest extent, can simplify the manufacturing model of disintegrating machine simultaneously, reduce manufacturing cost.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is a drill head and drill steel conical surface type of attachment example structure schematic diagram in addition.
The specific embodiment
Drill head 1 central authorities shown in Figure 1 are provided with a hole 3, the silk hole laterally have a pin-and-hole 4, the shape in set silk hole is consistent on the shape of drill steel 6 one ends and the drill head, this end drill steel transversely has a pin-and-hole 4 equally, and pin-and-hole and the steady pin in the pin-and-hole 4 that drill steel is screwed in the hole by each other are fastenedly connected.Label 5 among Fig. 1 is drill steel is connected an end place with drill head a screw thread, in the embodiment shown in fig. 1, is locked by steady pin 2 after the two is connected to each other by the screw thread screw thread again.Label 7 among Fig. 2 is drill steel is connected an end place with drill head conical surface termination, in embodiment illustrated in fig. 2, is locked by steady pin 2 after the two is connected to each other by drill head conical socket 3 and drill steel conical surface termination 7 again.Drill head can be processed into arbitrary shape as required, as pyramid, circle, globular model, wedge shape or the like.
Claims (3)
1. the drill steel on the hydraulic breaker, it is characterized in that: constitute by drill head (1) and drill steel (6) two-section, drill head central authorities are provided with groove or silk hole (3), groove or silk hole laterally have a pin-and-hole (4), the shape in set groove or silk hole is consistent on the shape of drill steel one end and the drill head, this end drill steel laterally has a pin-and-hole equally, and drill steel extend into that the pin-and-hole by each other and the steady pin in the pin-and-hole are fastenedly connected in groove or the silk hole.
2. as the drill steel on the said hydraulic breaker of claim 1, it is characterized in that: drill steel and drill head be screw thread silk by drill steel captacula hole and drill steel end after screw thread spins each other again by steady pin (2) locking.
