Description
Technical field
The utility model relates to pneumatic pick.
Background technology
Pneumatic pick is the important tool of coal production, and its pneumatic pick handle is generally to be made by materials such as metal or aluminium alloys, thus pneumatic pick handle intensity and toughness limited, easy fracture in operating process may cause operating personnel injured.Application number is 200820082458.6 the disclosed pneumatic pick of Chinese patent, as Figure of description 1, comprise pneumatic pick handle and pneumatic pick main body, pneumatic pick handle front end has cylindrical structure, the front end of cylindrical structure has end face, extend before and after the axis of described cylindrical structure on the barrel of described cylindrical structure and be provided with the stroke hole that coordinates for source of the gas tube connector guiding movement on pneumatic pick, described source of the gas tube connector passes described stroke hole and is threaded connection and is fixed on the pneumatic pick main body.Therefore, if the pneumatic pick handle damages because of reasons such as fractures, just need first the source of the gas tube connector is screwed off and just can fall coupling sleeve and extract out in the cylindrical structure of pneumatic pick handle, again the source of the gas tube connector is screwed in again after the pneumatic pick handle that more renews.Because the pneumatic pick handle often damages, the source of the gas tube connector also needs repeated disassembled and assembled, so stripped thread easily occurs in the threaded connection place, causes the source of the gas tube connector to break away from pneumatic pick under High Pressure and flies out in the other direction, thereby have influence on production safety, continuous production and production efficiency.Therefore, pneumatic pick need to often overhaul and purchase the needs that the accessories such as pneumatic pick handle, source of the gas tube connector, adapter, adapter sleeve satisfy maintenance, and maintenance cost is high.
The utility model content
The purpose of this utility model is to provide a kind of pneumatic pick handle of being convenient to disassembling, assembling and replacing, and a kind of pneumatic pick that uses this pneumatic pick handle is provided simultaneously.
The technical scheme that in the utility model, a kind of pneumatic pick handle adopts is: a kind of pneumatic pick handle, comprise for cover and install to cylindrical structure on the pneumatic pick coupling sleeve, be provided with along the Axis Extension of cylindrical structure the stroke groove that coordinates for source of the gas tube connector guiding movement on pneumatic pick on described cylindrical structure, described stroke groove has in the front end of cylindrical structure the opening that the air supply source tube connector passes through along the axis of cylindrical structure, on described cylindrical structure also in the removable pressing plate that coordinates with described source of the gas tube connector block of being used for that strides across described stroke groove that is fixed with of the opening part of described stroke groove.
Compare with the stroke hole of prior art sealing, the technical program has adopted the stroke groove of opening, if need dismounting or change the pneumatic pick handle, need not dismantle the source of the gas tube connector and the pneumatic pick handle can be unloaded from pneumatic pick.Also in the removable pressing plate that strides across described stroke groove that is fixed with of the open side of described stroke groove, the source of the gas tube connector is followed the journey groove be limited in travel range on described cylindrical structure, as long as unload this pressing plate during replacing, thereby facilitated disassembling, assembling and replacing.In addition, avoided the repeated disassembled and assembled of source of the gas tube connector during due to replacing, therefore be not prone to the stripped thread phenomenon, also can not cause the accident because stripped thread causes source of the gas tube connector disengaging pneumatic pick to fly out in the other direction.
Described cylindrical structure surface is installed with respectively in stroke groove both sides the bolt that is parallel to each other, and is located on described bolt and uses nut to fix by perforate thereby described pressing plate is provided with two perforates.Bolts and nuts are simple in structure, and convenient disassembly also can guarantee firmly to connect.
Described pneumatic pick handle rear end has handle, and described handle is to be made by the hard bending circular pipe; The cylindrical structure of described pneumatic pick handle is to be made by the hard metal pipe, and described handle is installed on described cylindrical structure.The handle of being made by the hard bending circular pipe and hard metal pipe are made cylindrical structure and are had higher intensity and toughness, can fracture under regular service conditions, can effectively reduce damage, and guarantee production efficiency and operating personnel's safety.
Described hard metal pipe is seamless steel pipe.Seamless steel pipe is easy to obtain, and cost of manufacture is low, and structural behaviour is good, can satisfy user demand.
The technical scheme that in the utility model, a kind of pneumatic pick adopts is: a kind of pneumatic pick, comprise the pneumatic pick handle, and described pneumatic pick handle comprises for cover and installs to cylindrical structure on the pneumatic pick coupling sleeve; Described pneumatic pick is provided with the source of the gas tube connector, Axis Extension along cylindrical structure on described cylindrical structure is provided with the stroke groove that coordinates for described source of the gas tube connector guiding movement, described stroke groove has in the front end of cylindrical structure the opening that the air supply source tube connector passes through along the axis of cylindrical structure, on described cylindrical structure also in the removable pressing plate that coordinates with described source of the gas tube connector block of being used for that strides across described stroke groove that is fixed with of the opening part of described stroke groove.Pressing plate is set described source of the gas tube connector can be followed the journey groove and be limited in travel range, the stroke groove of opening can make direct guiding skid off when needs are changed the pneumatic pick handle, has avoided repeated disassembled and assembled source of the gas tube connector, the convenient use.
Described cylindrical structure surface is installed with respectively in stroke groove both sides the bolt that is parallel to each other, and is located on described bolt and uses nut to fix by perforate thereby described pressing plate is provided with two perforates.Described pneumatic pick handle rear end has handle, and described handle is to be made by bending circular pipe; The cylindrical structure of described pneumatic pick handle is to be made by steel pipe, and described handle is installed on described cylindrical structure.Described hard metal pipe is seamless steel pipe.
Adopt the pneumatic pick of said structure, adopted the stroke groove of opening, if need dismounting or change the pneumatic pick handle, need not dismantle the source of the gas tube connector and the pneumatic pick handle can be unloaded from pneumatic pick.Also in the removable pressing plate that strides across described stroke groove that is fixed with of the open side of described stroke groove, the source of the gas tube connector is followed the journey groove be limited in travel range on described cylindrical structure, as long as unload this pressing plate during replacing, thereby facilitated disassembling, assembling and replacing.Pneumatic pick handle intensity is large in addition, is difficult for fracture, so long service life, can save maintenance cost.
