Abstract

A pneumatic chain saw comprises a chain saw body, an air compressor, a water supply cut-off protection device and a pressure bucket. The air compressor provides a power source for rotating the chain saw body, the pressure bucket provides cooling water in the working process, the cooling water and flushing water are outputted by the pressure bucket when voltage drives the air compressor to provide high-pressure air to the chain saw body, the chain saw body comprises a front plate, a rear plate, a chain saw, a chain guide plate, a guide plate bracket, a driving wheel, a driven wheel, a pneumatic motor, a speed regulation valve, a protection switch, a cooling water joint, a handle and a handgrip, and the pneumatic chain saw is used for high-speed cutting in a mine.

Description

The Pneumatic chain strap saw

Technical field

The present invention relates to a kind of chain saw of mine application, specifically a kind of pneumatic mining chain saw.

Background technology

The Pneumatic chain strap saw is that a kind of employing air compressor or high pressure air bottle driving air motor run up, and realizes the cutting tool of fly-cutting.Chain saw can be divided into Pneumatic chain strap saw, hydraulic link strap saw, manual-chain saw etc. according to mode classification is obstructed.Can be divided into mining chain saw according to the purposes difference, building chain saw etc.In the complicated Chamber Construction such as skip loading pocket in the shaft construction of mine first phase and the second stage of chamber, development work, use manual knife saw and electric chain strap saw to carry out the scene to wooden arch arch and the post leg of arch bar, irregular wall and arch bar and join mould.It is very large that the mould workload is joined at the scene of joining the post leg of mould, arch bar, irregular wall due to the arch of special cave room arch, utilize the manual knife saw duration very long, and the on-the-spot arch arch of allotting special cave room joined the mould irregularity of the post leg of mould, arch bar, irregular wall; Use the electric chain strap saw of prior art at underground construction, the electric chain strap saw leaks, electric leakage, spark, and phenomenon is inevitable, often causes the construction workman to get an electric shock; Therefore, designing a kind of high efficiency, Pneumatic chain strap saw that security is good, is the present technical issues that need to address.Present disclosed chain saw has a lot, but the Pneumatic chain strap saw is but seldom, be applied in mine the Pneumatic chain strap saw still less.

Summary of the invention

The invention solves the defectives such as manual working that prior art exists, chain saw complex structure, not environmental protection; provide that a kind of technical performance is advanced, simple in structure, low-carbon environment-friendly and bidirectional protective measure, make Pneumatic chain strap saw high efficiency, the better Pneumatic chain strap saw of security.

The technical solution adopted for the present invention to solve the technical problems is: this device comprises compressor, pressure bucket, means for protecting power device when water-break, chain saw.Air compressor is connected with chain saw by tracheae, and the pressure bucket is connected with chain saw by water pipe, and means for protecting power device when water-break is between pressure bucket and air compressor simultaneously.This device operation principle is for providing power resources to rotate to chain saw by air compressor, is provided at cooling water in the course of work by the pressure bucket simultaneously.Pressure bucket output cooling water and flushing water when voltage band engine-driven air compressor provides pressure-air to chain saw.This device is that 4 kilograms of pressure of pressure bucket output are opened valve to means for protecting power device when water-break with means for protecting power device when water-break; the pressure bucket water level reduces; pressure is during lower than 4 kilograms, and means for protecting power device when water-break valve autoshutdown cuts off air compressor and exports with the air pressure of chain saw.This device has duplicate protection: first heavily protects speed governing valve and discharge cock, and the speed governing valve must be pressed simultaneously with insurance.The second heavily protection, priming apparatus has the water cut-off protection ability, plays the cut-out power source under hydraulic pressure is cut off the water supply situation not and suddenly the saw head is quit work.

The chain saw of this invention is comprised of header board, rear plate, chain saw, chain guide, guide plate carriage, driving wheel, driven pulley, air motor, flow speed control valve, protection switch, cooling water connector, handle, handgrip; be chain saw around chain guide; the chain guide front end is that driven pulley, rear end are driving wheel; guide plate bracket support chain guide is fixed in the middle of front and rear panels; handgrip is in the air motor rear end; cooling water connector is fixed on handgrip top; flow speed control valve and protection switch are separately fixed to be convenient to debugging and to control on handgrip, handle is fixed on the guide plate carriage.

Handle shape is convenient to hand and is caught for " U " type.

Handgrip is shaped as " O " type and is convenient to hold.

Effect intentionally of the present invention is: duplicate protection, property time saving and energy saving, simple to operate, easy to use, safe is good.

The specific embodiment

Below in conjunction with accompanying drawing, embodiments of the invention are described.

Drive compressor operating as Fig. 1 voltage drive motor; send pressure-air by compressor; lead to filter by cylinder tracheae under the protection of safety valve; arrive pressure regulator valve by tracheae; pressure regulator valve arrives gauge tap through tracheae; gauge tap is to the gas motor; gauge tap is realized operation and is stopped; the cooling water connector of diamond chain saw provides cooling water and flushing water for main frame; in addition with means for protecting power device when water-break; the rear automatic-closing valve of cutting off the water supply stops the work of saw head, for preventing cutting off the water supply suddenly rear chain according to produce high temperature and spark under exsiccosis.

Whether the tightness and the hold-down nut that at first check chain during work are tightened, and then means for protecting power device when water-break is connected on the saw head.Then before connection, with the careful wiped clean of joint, check to connect whether put in place, have or not gas leak phenomenon with clean cotton when connecting compression gas pipe.First opened at last water supply installation and supply water before starting chain saw, then press discharge cock, cocking begins operation.
