Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of quartering hammer, the stopping means of drill steel in particularly a kind of quartering hammer.
Background technology
Quartering hammer comprises the movement of core, and this movement comprises front-bank rotor housing, middle cylinder body and rear-bank rotor housing, and its inside is plugged with piston rod and drill steel, is provided with hermetically-sealed construction and dustproof construction between the medial surface of middle cylinder body and the piston rod.Front-bank rotor housing is the main working parts of quartering hammer; Present various construction standards of the same trade also fail to control timely and effectively this structure failure both at home and abroad; Cause the influence of various heavy construction operations and the waste of national resources, we have done deep research to the structure of these parts, find that the reason great majority of various front-bank rotor housing fractures are to be cotter pilotage mouth place; Therefore, wanting to reach the long-lived standard only way of front-bank rotor housing is to readjust relevant critical pieces such as cotter pilotage, lateral pin.
Summary of the invention
The purpose of the utility model is the problems referred to above that exist to existing technology; The stopping means of drill steel in a kind of quartering hammer is provided, and the utility model technical problem to be solved is the extruding that the drill steel motion causes front-bank rotor housing when having avoided cotter pilotage or lateral pin fracture to drop.
The purpose of the utility model can realize through following technical proposal: the stopping means of drill steel in a kind of quartering hammer; This stopping means is arranged between front-bank rotor housing and the drill steel, it is characterized in that, has chute on the middle part lateral surface of drill steel; Radially be inserted with cotter pilotage in the described chute; Offer locating hole one and locating hole two on the medial surface of described front-bank rotor housing respectively, the two ends of described cotter pilotage extend to outside the chute and are plugged on respectively in locating hole one and the locating hole two, and an end of described cotter pilotage has locating hole three radially; Be plugged with a lateral pin in the described locating hole three, the two ends of described lateral pin are connected on the front-bank rotor housing.
The operation principle of this device is following: when piston rod promotion drill steel is done the forward-reverse motion; Cotter pilotage and chute slide relatively, and after sliding into certain displacement, the end face of cotter pilotage and chute leans; Thereby, drill steel can not be moved on or retreat with the drill steel location.This device makes original two lateral pins into a lateral pin; The length of cotter pilotage is increased to is plugged on the front-bank rotor housing; The intensity and the service life of cotter pilotage have not only been strengthened; And after cotter pilotage fracture, can from locating hole one or locating hole two, drop out, can be not stuck in front-bank rotor housing, thus the extruding that the drill steel motion causes front-bank rotor housing when having avoided cotter pilotage or lateral pin fracture to drop.
In above-mentioned a kind of quartering hammer in the stopping means of drill steel; Described chute has both sides; And the axis along drill steel is symmetrically distributed on the two sides of drill steel respectively; Described cotter pilotage also has two and be plugged on respectively in the chute, and described lateral pin is located in simultaneously on two cotter pilotages and with these two cotter pilotages and front-bank rotor housing and fixes.
In the stopping means of drill steel, the width of described chute is much larger than the bore of cotter pilotage in above-mentioned a kind of quartering hammer.The cotter pilotage end distance that can in chute, slide leaves like this.
In above-mentioned a kind of quartering hammer in the stopping means of drill steel; Have pin-and-hole one and pin-and-hole two on the described front-bank rotor housing; The two ends of described lateral pin are plugged on respectively on pin-and-hole one and the pin-and-hole two; And this pin-and-hole one and pin-and-hole two are positioned at the top of front-bank rotor housing, and the bore of said pin-and-hole two is greater than the bore of pin-and-hole one, and this pin-and-hole two is positioned near the driver's cabin side.Lateral pin is arranged on the top of front-bank rotor housing, makes after the cotter pilotage fracture, can under the effect of conducting oneself with dignity, drop out front-bank rotor housing, the pin-and-hole two that relative aperture is bigger makes the driver can observe the situation of cotter pilotage and lateral pin towards driver's cabin.
Compared with prior art; This device makes original two lateral pins into a lateral pin; The length of cotter pilotage is increased to is plugged on the front-bank rotor housing, not only strengthened the intensity and the service life of cotter pilotage, and after the cotter pilotage fracture, can from locating hole one or locating hole two, drop out; Can be not stuck in front-bank rotor housing, thus the extruding that the drill steel motion causes front-bank rotor housing when having avoided the fracture of cotter pilotage or lateral pin to drop.Lateral pin is arranged on the top of front-bank rotor housing, makes after the cotter pilotage fracture, can under the effect of conducting oneself with dignity, drop out front-bank rotor housing, the pin-and-hole two that relative aperture is bigger makes the driver can observe the situation of cotter pilotage and lateral pin towards driver's cabin.
