Description
Technical field
The present invention relates to a kind of tunnel telescoping steel form automatic ash removing and brushing releasing agent device, belong to Hydraulic and Hydro-Power Engineering tunnel Hole concrete steel trolley formwork ash removing equipment.
Background technology
Telescoping steel form is a kind of to improve tunnel-liner surface smoothness and lining cutting speed, and reduces labor intensity and set Meter, the special equipment of manufacture.Telescoping steel form has side and roof arch formula, stalk variable cross-section crown formula, whole-circle needle beam type, wholecircle traveling type Deng.Formwork jumbo basic structure is by template part, door frame body portion, running gear, supporting mechanism, translation system and other attached Belong to device several major composition.Telescoping steel form actual installation general sequence in hole is：Layering from inside to outside is installed, installation Particular order is：Bed die → portal → both sides side form and its support (bearing diagonal and horizontal support) → backform and its support → its Its annex.Higher than conventional template by 30%, fast 2~3 times of the die-filling, stripping rate that pours effect using telescoping steel form, manpower used is Past 1/5.
Current Hydraulic and Hydro-Power Engineering tunnel concrete typically carries out lining cutting using telescoping steel form（Especially for medium-and-large-sized disconnected Face tunnel）, because hydraulic tunnel is higher to lining concrete flow surface appearance requirement, to ensure tunnel flow surface concrete Molded appearance quality, it is necessary to ensure that telescoping steel form template surface must keep cleaning, releasing agent brushing uniform.It is now domestic main Using the method for brush releasing agent is handled again after man-hour manually hand-held angle grinder deashing.
Because tunnel concrete liner thickness is typically relatively thin, and to accelerate concrete lining speed, lining cutting reinforcing bar typically surpasses Preceding 2 standard storehouses are completed, and cause operating space narrow, artificial deashing speed is slower, and second-rate, operating environment is poor. Telescoping steel form manufacturing cost is higher, and many set telescoping steel forms of input are unrealistic, and every telescoping steel form heavier-weight, volume are huge Greatly, dismounting carries out deashing, brushing releasing agent in tunnel, infeasible from technology, cost and on the duration.
The content of the invention
The present invention can realize the template for intending being placed on installation on tunnel telescoping steel form to solve the above problems, invention is a kind of Carry out automatic ash removing and carry out the device of automatic painting releasing agent.
The present invention seeks to what is completed by having structure：A kind of tunnel telescoping steel form automatic ash removing and brushing releasing agent Device, it is characterised in that：By automatic ash removing device（1）, automatic painting releasing agent device（2）Constitute, the automatic ash removing device Pass through several bars each other with automatic painting releasing agent device（3）It is fixedly mounted on again on tunnel inner wall wall after connection, Or single automatic ash removing device（1）With fixed and adjusting means（6）It is arranged on again on tunnel inner wall wall after independently fixing, or The single automatic painting releasing agent device of person（2）Independently it is fixedly mounted on tunnel inner wall wall；
The automatic ash removing device is ground the angle grinder for wire brush by angle（1a）, channel-section steel（1b）, reinforcing bar（1e）Constitute, institute State angle grinder and be bolted to channel-section steel（1b）On, fixed and adjusting means（6）It is welded in channel-section steel (1b) back side.
The channel-section steel（1b）The portal body with intending construction tunnel lining section same shape, channel-section steel is made in shape（1b）Can It is an entirety or is segmented with reference to lining steel formwork jumbo template, takes articulated manner to connect between each section.
The automatic ash removing device（1）By two channel-section steels（1b）Use reinforcing bar（1e）It is welded into side by side, each channel-section steel（1b） On several corner of table grinding machines are fixed with bolt（1a）, and two channel-section steels（1b）On angle grinder（1a）Staggered relative is installed.
The fixation and adjusting means（6）In spring（6a）One end is socketed in helical screw（6b）One end constitute fix And adjusting means（6）, spring (6a) other end is welded in channel-section steel（1b）The back side, helical screw（6b）The other end be fixed on tunnel On wall.
The automatic painting releasing agent device（2）By pump machine or sprayer（2a）, steel pipe（2b）, roll cotton brush（2c）Structure Into the pump machine or sprayer（2a）By leather hose and steel pipe（2b）Connection, is provided with the several steel pipe of aperture（2b）It is set in rolling Dynamic cotton brush（2c）It is interior, fixed and adjusting means（6）Connect steel pipe.
The steel pipe（2b）The portal body of shape after lining trolley shrinks is bent to, and by fixing and adjusting means（6） It is installed in tunnel interior walls.
With steel pipe（2b）The rolling cotton brush of bending section connection（2c）For piecewise combination, side wall two parts steel pipe（2b）On rolling Dynamic cotton brush（2c）It is respectively independent entirety or segmentation connection.
The steel pipe（2b）It is set in rolling cotton brush（2c）It is interior, steel pipe（2b）One end pass through leather hose and pump machine or spraying Device（2a）Connection, other end closure is dead.
It is of the invention mainly to include two complete equipments：One is automatic ash removing device, uses what wire brush was ground for angle by several Angle grinder is fixed by bolts on channel-section steel, and channel-section steel bends to identical with tunnel lining section, and this device is arranged on into tunnel mouthful Pour at section, in all angle grinder angles, telescoping steel form moving process is started during chassis movement is in place angle grinder to punching block Trolley formwork is polished, after telescoping steel form is in place, removes automatic ash removing device, that is, completes telescoping steel form deashing.The second is from Dynamic brushing releasing agent device, this is using a steel pipe, and it is several to be drilled with aperture on steel pipe, and steel pipe socket is being loaded on into rotatable cotton In brush, pump machine is utilized（Or sprayer）Automatic ash removing device is arranged on by the continual press-in steel pipe of releasing agent, and by the equipment Rear position, in chassis moving process, cotton brush is rolled along template by the frictional force of chassis and completes telescoping steel form template brushing Releasing agent is constructed.
Using the invention device, deashing and the operation of brush releasing agent of telescoping steel form template can be slided in telescoping steel form（Then With movable process）During simultaneously complete, be not take up the cycle operation time, accelerate speed of application, it is ensured that tunnel coagulation While native surface forming quality, further improve workman's operating environment and labor intensity, ensure that operating personnel it is healthy, And it is cost-effective, and used equipment is simple, and processing and fabricating and installation are easy, feasible process.
As a further improvement on the present invention, on channel-section steel angle grinder installation number, angle grinding size, rolling cotton brush size It can be increased or decreased according to site operation requirement.
