Description
Technical Field
The invention relates to the technical field of tunnel waterproof construction, in particular to a low-vibration waterproof board auxiliary laying construction device for a high-speed rail tunnel.
Background
The tunnel is an increasingly common constituent part of highways and railways, and in modern tunnel construction, waterproof engineering is an important constituent part, and the construction quality of the waterproof engineering directly influences the subsequent use and the convenience of maintenance of the tunnel.
The waterproof engineering is mainly that firstly, the geotextile is nailed on the arch surface of the tunnel, then the hot melt adhesive is pasted, finally, the waterproof board (the waterproof cloth) with good waterproof and evaporation prevention is pasted, the hot melt adhesive is heated to fix the waterproof board, and then the main waterproof engineering is completed.
In the current domestic tunnel waterproofing engineering construction, the mode of laying is adopted to the manual work mostly, the form that adds the work basket through the work rack lifts the eminence with the workman, a set of constructor lifts the waterproof board, another group heats fixedly, still need low department personnel supply waterproof board and remove the work rack, the constructor is more, intensity of labour is great, and, the fold problem appears sometimes to massive waterproof board, it is just in addition that the joint position is in order to guarantee not to leak water, the overlap section is too much, beat in the tunnel, the work rack is numerous, factors such as frequent removal can cause vibration volume and noise in the tunnel, vibration noise makes a round trip to reflect in the tunnel, deteriorate workman operational environment.
Disclosure of Invention
The invention aims to provide a low-vibration waterproof board auxiliary laying construction device for a high-speed rail tunnel, which aims to solve the problems in the background technology.
In order to solve the technical problems, the invention provides the following technical scheme:
the utility model provides a low-vibration's high-speed railway is supplementary construction equipment of laying of waterproof board for tunnel, including the truss, the travelling wheel, the track, lay subassembly and board book roller, the truss bottom sets up the travelling wheel, the travelling wheel can follow the tunnel axial and advance, truss circumference outer fringe sets up and lays the subassembly with the face-to-face track of tunnel inner wall, set up on the track, the board book roller sets up on the truss, place the package waterproof board on the board book roller, one end tractive of waterproof board is to laying on the subassembly, lay the subassembly along attached tunnel inner wall with the waterproof board when the track walking on. Traditional waterproof board's attached all lets operating personnel stand on it and then manual with the waterproof board attached to the tunnel inner wall then fix through the form of workstation, the operator divides several people, at least lay the waterproof board with lay after with waterproof board and underrun hot melt adhesive veneer, and this application passes through the circular arc track, lay the subassembly through walking on the circular arc track and automatically lay the waterproof board go up and fix, operating personnel only need when the machine is not laid the waterproof board according to expectation and to the tunnel archway bottom both sides the position carry out waterproof board fill can, lay the one deck along tunnel length direction after, the travelling wheel advances a length unit's distance, begin the waterproof board of next cycle and lay.
Further, lay the subassembly including the driving base, the support arm, first support arm, the clamp plate wheel, the interlock wheel, driving base bottom both sides set up the interlock wheel, the interlock wheel is hugged closely the track and is slided along the track, support arm one end is installed and is deviated from orbital one side at the driving base, the first support arm of support arm other end hinge joint, the clamp plate wheel is installed to the other end of first support arm, the waterproof board is attached to the tunnel inner wall after rolling around the clamp plate wheel on, support arm and first support arm hinge position set up torsion spring and make the clamp plate wheel have the trend of keeping away from the track. The driving base passes through the mounted position for support arm and follow-up runner structure, it self walks along the guide rail through the interlock wheel, the tunnel inner wall can be hugged closely to the clamp plate wheel in the existence of torsional spring between support arm and the first support arm, when some deviations and local protruding take place for tunnel inner wall size, first support arm and clamp plate wheel take place the rotation of certain angle around the support arm tip, the clamp plate wheel meets the obstacle and gives up, meet the sunken filling that gos forward, can let the waterproof board lay on the tunnel inner wall not have the clearance, guarantee to lay the quality.
Further, lay the subassembly and still include the take-up pulley, the driving base intermediate position sets up the board groove, crosses the board groove and be the rectangle through-hole, and the take-up pulley includes two, and the take-up pulley sets up respectively at the both ends of crossing the board groove, and the waterproof board arrives the clamp plate wheel after walking around the take-up pulley. The take-up pulley lets the waterproof board become the transmission that the waterproof board carried out the waterproof board of state of tightening, prevents especially that the waterproof board from producing waterproof board length direction fold when being about to reach the clamp plate wheel and carry out tunnel inner wall and attach, and this fold arouses the waterproof performance of waterproof board to descend easily.
Further, lay the subassembly and still include the second support arm, auxiliary wheel and switching-over gear train, second support arm one end is articulated with the middle part of first support arm, one end installation auxiliary wheel, the articulated position of second support arm and first support arm sets up torsion spring and makes clamp plate wheel and auxiliary wheel have the trend of being close to each other, the switching-over gear train includes two gears, two gears set up respectively at the same end of the axial of clamp plate wheel and auxiliary wheel, the waterproof board passes through the auxiliary wheel on the route from take-up pulley to clamp plate wheel, the auxiliary wheel surface sets up the screw direction of two sets of symmetries screw thread outwards.
