Detailed description of the invention
By reference to the accompanying drawings the specific embodiment of the present invention is described further.
Trolley structure is built in the rainproof movement of one precast bridge concrete
The rainproof movement of precast bridge concrete is built chassis and is made up of running truck, rack platform, receiving hopper, fixed chute, rotating chute five part.See accompanying drawing 1.
1, running truck
Running truck is electric track flatcar, is driven by battery.The track of the steel rail laying inside bridge formwork is walked, can to contraposition discharging between each sections of bridge length direction.Chassis two ends are respectively provided with two rail clamping devices.Rail clamping device is a pincer structure.Be made up of two clamping plates and an adjusting screw.There is connecting screw hole clamping plate upper end, to be arranged on by rail clamping device on the horizontal rotating shaft under running truck by screw.Rail clamping device can rotate up and down around axle.During running truck traveling, rail clamping device hook is sling, and leaves rail level.After running truck is in place, put down rail clamping device, outside adjusting screw makes two clamping plate be separated by tread, and when clamping plate head drops down onto rail web, inside adjusting screw, until clamping plate head clamping rail web.Rail clamping device structure is shown in Fig. 6,7.
2, rack platform
Rack platform shaped steel is made, and is arranged on running truck, for miscellaneous equipment provides installing space.Rack platform is provided with operating platform, for operative provides the scope of operation.Rack platform top welded steel plate frame top awning lid, prevents rainwater from entering chute.
3, receiving hopper
Receiving hopper welded steel plate forms, and is arranged on rack platform top, is used for concrete of unloading.Movable steel receiving hopper rainhat is set above receiving hopper, removes during concrete bucket discharging, unsnatch on material bonnet.Receiving hopper rainhat is a umbrella-shaped structure, and its side is provided with an axle sleeve, can be set in rotating shaft that rain-proof fluffied covers.Promote handle during use, just receiving hopper rainhat can be pivoted and remove or cover.Its opposite side is provided with latch, after receiving hopper rainhat covers, receiving hopper rainhat can be fixed on rain-proof fluffied and cover; Receiving hopper rainhat structure is shown in Fig. 4,5.
4, fixed chute
Fixed chute is fixedly mounted on rack platform.Chute groove body horizontal slope 30 °.Fixed chute is suitable for reading under the discharging opening of receiving hopper, and end opening is on rotating chute is suitable for reading.Concrete to be slipped by fixed chute from receiving hopper outlet and delivers to rotating chute.
5, rotating chute
Rotating chute welded steel plate forms, and is obliquely installed and rotates to be installed on rack platform.Cell body upper end is welded on rotating shaft.Cell body divides into a pole, and the upper and lower side of pole is welded in cell body and rotating shaft respectively.The upper and lower end of rotating shaft is arranged in upper and lower bearing block.Top chock is installed on rack platform bottom, and step is installed on running truck top.Therefore, cell body and rotating shaft can together with do 180 ° of rotations.Chute groove body horizontal slope 30 °.The height of rotating chute end opening is higher than the upper open height of bridge formwork, and position can reach in the middle of bridge web.
Two, chassis use is built in the rainproof movement of precast bridge concrete
Before chassis moves, pack up rail clamping device, and rotating chute is rotated to groove body and beam forms parastate, collide to avoid chute and template awning column.Then start chassis, chassis is moved to the position that bridge formwork needs casting concrete.See Fig. 3.
After chassis is in place, puts down rail clamping device and be clamped on rail, and rotating chute is rotated to groove body and beam forms upright position.Now, can start to lift above concrete hopper to chassis receiving hopper, remove rainhat on receiving hopper, open concrete hopper bottom valve and unload concrete in receiving hopper.Concrete is slipped by fixed chute and swivel chute to be delivered in bridge formwork, carries out concreting.See Fig. 2.
