Abstract

The utility model provides a spraying device is restoreed to non-excavation formula box culvert that descends, is including setting up screw pump and the motor in the frame, and the pan feeding storehouse is located screw pump's top, and the upper portion quick detach formula of going into the feed bin is connected with the increase volume hopper, and the frame bottom surface has arranged the several and has removed the wheel, and removes the wheel and form collapsible formula connection structure that draws in through hinge seat and frame, and the tail end of frame still is fixed with rings. The utility model has the advantages of compact and reasonable overall structure, can dismantle the increase-volume hopper fast, remove the wheel and fold rapidly and draw in the peripheral diameter that reduces equipment in to utilize rings can put into the inspection shaft that the box culvert was passed through to the vertical hoist and mount of whole device, need not the excavation and can haulage equipment get into inside the box culvert, improved the flexibility and the work efficiency that the box culvert was restoreed the work progress greatly, reduce work load, reduction of erection time.

Description

Non-excavation formula box culvert restoration spraying device that falls into well

The technical field is as follows: the utility model relates to a building engineering construction machinery especially is used for prosthetic construction equipment of box culvert.

Background art: the box culvert generally refers to a culvert built by reinforced concrete box pipe joints, and can be used for drainage, people passing and vehicle passing. After long-term use, the inner wall of the box culvert can have the problems of surface layer corrosion, shedding, abrasion, cracks, leakage and the like, and special slurry is required to be mixed on site and sprayed or grouted for repair. The existing construction restoration method generally needs to excavate a box culvert to form a construction channel, a corresponding restoration construction device can be moved into operation, and the box culvert needs to be backfilled after restoration is completed, so that the cost is high, the workload is large, and the construction period is long. If do not excavate, the inspection shaft that only can utilize the box culvert gets into constructor nevertheless can't pass through existing equipment, and the construction can only rely on from the long-range hose and the spray gun of drawing in of ground equipment to carry out the operation, and spraying pressure is low, and the regional distance that can the construction operation is very limited, and the scope is little.

The invention content is as follows: not enough to prior art, the utility model provides a compact structure, the non-excavation that the trafficability characteristic is good is gone into the pit and is contained formula and restore spraying device.

The utility model discloses a screw rod delivery pump and the motor of setting in the frame, pan feeding storehouse are located screw rod delivery pump's top, and the quick detach formula in upper portion of going into the feed bin is connected with the increase volume hopper, and the several has been arranged to the frame bottom surface and has been removed the wheel, and removes the wheel and form collapsible formula connection structure that draws in through hinge seat and frame, and the tail end of frame still is fixed with rings.

The utility model has the advantages of compact and reasonable overall structure, can dismantle the increase-volume hopper fast, remove the wheel and fold rapidly and draw in the peripheral diameter that reduces equipment in to utilize rings can put into the inspection shaft that the box culvert was passed through to the vertical hoist and mount of whole device, need not the excavation and can haulage equipment get into inside the box culvert, improved the flexibility and the work efficiency that the box culvert was restoreed the work progress greatly, reduce work load, reduction of erection time.

The invention is further described with reference to the accompanying drawings and the detailed description.

Description of the drawings: fig. 1 is a main schematic view of the embodiment.

Fig. 2 is a top view of fig. 1.

Fig. 3 is a schematic perspective view of the embodiment.

Fig. 4 is a schematic view of the embodiment in a folded vertical hoisting state.

The specific implementation mode is as follows: as shown in fig. 1 to 3, a screw conveying pump 2 and a motor 3 are provided in a frame 1, a feeding bin 4 is located above the screw conveying pump 2, and a capacity-increasing hopper 5 is connected to an upper portion of the feeding bin 4 in a quick-release manner. A plurality of moving wheels 6 are arranged on the bottom surface of the frame 1, and the moving wheels 6 and the frame 1 form a foldable connecting structure through a hinge seat 7. The tail end of the frame 1 is also fixed with a hanging ring 8.

The front plate 9 of the feeding bin 4 facing the front end of the frame 1 in the embodiment is a bent inclined surface which inclines forwards, so that the volume of the feeding bin 4 can be increased while the whole length is reduced as much as possible. The pump body dismounting slideway 10 is arranged in the frame 1 and at the left and right positions of the screw conveying pump 2, so that the screw conveying pump 2 is more convenient to dismount, replace and overhaul.

When the device needs to be transported into a box culvert, as shown in fig. 4, the capacity-increasing hopper 5 is rapidly disassembled, and each moving wheel 6 is folded to reduce the peripheral diameter of the device, and then the lifting ring 8 is utilized to vertically lift the whole device and place the device into the inspection well of the box culvert. After entering the box culvert, the capacity-increasing hopper 5 is mounted, and each movable wheel 6 is opened and reset, so that the construction operation and the movement are convenient.
