In the present embodiment, pressure source tube connector 334 is oil connection, and cylinder body 331 is integral with being fixedly connected with the first end cap 332 of boss and oil connection.Before not passing into hydraulic oil in the pressure source tube connector 334, piston 333 is in initial position, and under the effect of spring assembly 321, the end face A of piston 333 and the end face B of boss fit.In the present embodiment boss and and oil-in between the setting of position relationship, being communicated with of inner space of having guaranteed oil-in and cylinder body 331.
As shown in Figure 7, ironing machine also comprises the connection power drive mechanism, it comprises accumulator 61, the first end of accumulator 61 is connected with pressure source, its second end is connected with pressure source tube connector 334, and accumulator 61 is used for when clamp mechanism 30 is in clamped condition the oil pressure in the cylinder body 331 being carried out pressurize.Connect power drive mechanism and also comprise the overflow mechanism 63 that all is connected with pressure source and pressure source tube connector 334, be used for limiting the inside maximum pressure of cylinder body 331.Connect power drive mechanism and also comprise the pressure monitoring mechanism 64 that is connected with pressure source tube connector 334, be used for the internal pressure of monitoring cylinder body 331.
According to one embodiment of present invention, overflow mechanism 63 is overflow valve, and pressure monitoring mechanism 64 is pressure switch or pressure sensor.Connecting power drive mechanism is comprised of the elements such as valve, overflow valve, pressure switch or pressure sensor that accumulator 61, stop valve 62 or other types can play the effect of blocking-up oil circuit, connect power drive mechanism one end and connect pressure source with hydraulic hose 65, the other end picks out hydraulic hose 65, and the termination of this hydraulic hose 65 is with snap joint 69.This connection power drive mechanism is installed on paver main frame or the basic screed 10.Particularly, in the present embodiment, snap joint 69 is by oil pipe distributing valve piece 68 and hydraulic oil pipe 67 direct Bonding pressure source tube connectors 334.
The leakage that accumulator 61 can carry out pressurize and replenish each Hydraulic Elements fluid the oil pressure in the cylinder body 331 of clamp mechanism 30 is to guarantee the clamping force of clamp mechanism.Work as oil liquid leakage, when in-oil cylinder oil pressure reduces to the threshold value of pressure switch or pressure sensor setting, connect power drive mechanism and open gauge tap, in time give cylinder body 331 interior pressurisings.The maximum value of pressurising is set by overflow valve.All the time between the value that value that pressure switch or pressure sensor are set and overflow valve are set, guaranteed has enough clamping forces between two screeds to the size of the clamping force of clamp mechanism.In addition, can adjust quickly the setting value of pressure switch or pressure sensor, overflow valve according to actual conditions, obtain the clamping force of different clamp mechanism, can satisfy the connection between different size size screed.As from the foregoing, the required power of different screeds connections can be according to the actual conditions quick adjustment.
As shown in Figure 7 and Figure 8, be connected by a plurality of clamp mechanism between two interconnective screeds.Because a plurality of clamp mechanism are connected with the aforesaid power drive mechanism that is connected by hydraulic oil pipe 67 respectively, the clamping force that therefore connects each clamp mechanism 30 on the end plate is basic identical, so the integral rigidity of screed is better.
According to one embodiment of present invention, when prolonging the working width of screed, after the support bar 335 that lengthens screed 40 upper clamping mechanisms 30 inserted load hole 121 corresponding on the basic end plate 11 of the basic screed 10 that is connected, put into locating hole 122.Then adjust regulating part 21, the base plate 83 of two adjacent screeds is on the same horizontal plane.Connect dynamical system with connecting power drive mechanism, the hydraulic hose 65 with snap joint 69 on the connection power-driven system connects the pressure source tube connector 334 that lengthens on the screed.Open the gauge tap that connects power drive mechanism, under the driving of hydraulic coupling, the plain washer 313 on the support bar 335 is fitted on the basic end plate 11 of the basic screed 10 that is connected, and finally clamps two adjacent screeds.
When dismounting lengthens screed 40, open the gauge tap that connects power drive mechanism, make the fluid oil sump tank in the cylinder body 331 of clamp mechanism 30, unclamp the snap joint 69 that is connected on connecting power drive mechanism and lengthening screed 40, this moment, support bar 335 stretched out under the effect of the spring assembly 321 of piston 333 ends.Make the lengthening end plate 41 of the lengthening screed 40 that clamp mechanism 30 is installed and the distance L between the plain washer 313 be slightly larger than the thickness of the basic end plate 11 that basic screed 10 will be connected, lift the section of adding screed 40, the plain washer 313 on the clamp mechanism is extracted out from the load hole 121 of the basic end plate 11 of the basic screed 10 that is connected.Thereby realizing lengthening screed 40 disassembles from whole paver.
The present invention loads and unloads screed fast, can realize lengthening quick assembling and the dismounting of screed according to paving the variation of working width, and greatly lighter operator's labour intensity, and is time saving and energy saving.And be not subjected to the impact of the mechanism vibrations such as hammer ram, vibrator, its clamping force remains in the predefined scope.Make screed that enough integral rigidity be arranged, thereby guaranteed the spreading quality on road surface.
The present invention also provides a kind of paver, comprises aforesaid ironing machine.
The width that paver of the present invention is required according to paving concrete pavement can be realized the loading and unloading of screed fast, and it is basic identical to connect end plate connection power everywhere, has improved the integral rigidity of screed.In addition, paver of the present invention can it connects the size of power according to the actual conditions quick adjustment, thereby has guaranteed the stable connection between the screed, has guaranteed the spreading quality on road surface.
As can be seen from the above description, the above embodiments of the present invention have realized following technique effect:
Be not subjected to the impact of hammer ram front apron when 1, the screed of paver lengthens;
2, no longer need artificial tightening fastener parts, operator's labour intensity is little;
3, loading and unloading lengthen the speed of screed;
4, the clamping force of each clamping cylinder is basic identical on the connection end plate, causes the integral rigidity of screed better;
5, connecting required power can be according to the actual conditions quick adjustment.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
