Description
Technical Field
The utility model relates to a cut-off box that especially uses on canal formula cutting cement continuous wall construction equipment belongs to secret basic construction machinery technical field.
Background
In the existing trench type cutting cement continuous wall construction equipment, for example, a cutting box used on a TRD construction machine, a slot milling machine and the like, a grout outlet of the cutting box is reversely cut off by a circular nylon plate or a rubber plate and a moon-shaped pressing plate, but the nylon or the rubber is easy to age, and the moon-shaped pressing plate presses the circular nylon plate or the rubber plate to easily break the circular nylon plate or the rubber plate, so that the reverse cut-off cannot be realized to block a grout pipe or an air pipe in the cutting box, the construction is interrupted, and the construction efficiency is influenced.
Disclosure of Invention
The utility model discloses to the not enough that exists among the prior art, invented a cut-off formula cutting box, should cut-off formula cutting box novel structure, it is reliable to end the effect, can effectively prevent the stifled pipe of cutting box thick liquid trachea, improves the efficiency of construction.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the cut-off type cutting box comprises a cutting box body, a slurry gas inlet pipe 1 arranged in parallel along the length direction of the cutting box body and a slurry gas outlet pipe 2 arranged perpendicular to the length direction of the cutting box body are arranged in the cutting box body, one end of the slurry gas outlet pipe 2 is communicated with the slurry gas inlet pipe 1, a check ring 3 is installed at the other end of the slurry gas outlet pipe 2, a seal plate 4 and a hinge pin 5 are arranged in the cutting box body, the outer peripheral surface of the check ring 3 is connected and sealed with the inner peripheral surface of the slurry gas outlet pipe 2, a through hole is formed in the check ring 3, the axis of the through hole is parallel to the axis of the slurry gas outlet pipe 2, a seal plate 4 is arranged on the outer side surface of the check ring 3, the inner side surface of the seal plate 4 is in contact with the outer side surface of the check ring 3, and the hinge pin 5 penetrates through lug holes in the seal plate 4 and the check ring 3.
In a preferred embodiment, the slurry gas inlet pipe 1 and the slurry gas outlet pipe 2 are both circular pipes, and the outer circumferential surface of the retainer ring 3 is connected and sealed with the inner circumferential surface of the slurry gas outlet pipe 2.
As another preferred embodiment, the closing plate 4 is a circular closing plate, and the circular hinge pin 5 passes through circular ear holes on the closing plate 4 and the retainer ring 3.
Drawings
FIG. 1 is a schematic structural diagram of a cut-off type cutting box.
Detailed Description
The attached drawing is a schematic structural diagram of a cut-off type cutting box. The metal cut-off type cutting box in the drawing comprises a cutting box body, wherein a circular slurry gas inlet pipe 1 and a circular slurry gas outlet pipe 2 are arranged in the cutting box body in parallel along the length direction of the cutting box body, the circular slurry gas inlet pipe 2 is perpendicular to the length direction of the cutting box body, one end of the slurry gas outlet pipe 2 is communicated with the slurry gas inlet pipe 1, a circular retainer ring 3, a circular retainer plate 4 and a circular hinge pin 5 are arranged at the other end of the slurry gas outlet pipe 2, the outer circumferential surface of the retainer ring 3 is connected and sealed with the inner circumferential surface of the slurry gas outlet pipe 2, a circular through hole is formed in the retainer ring 3, the axis of the through hole is parallel to the axis of the slurry gas outlet pipe 2, the circular retainer plate 4 is arranged on the outer side surface of the retainer ring 3, the inner side surface of the circular retainer plate 4 is in contact and sealed with the outer side surface of the retainer ring 3, and the circular hinge pin 5 penetrates through circular lug holes in the upper portions of the circular retainer plate 4 and the circular retainer ring 3.
When the cutting box drills downwards, equipment such as an air compressor, a slurry pump and the like is started, and compressed air or cement slurry or water and other media enter the slurry gas outlet pipe 2 from the slurry gas inlet pipe 1 and pass through the retainer ring 3. Because the pressure in the slurry gas outlet pipe 2 is greater than the pressure of the medium such as liquid soil in the groove outside the sealing plate 4, the sealing plate 4 rotates along the hinge pin 5 to open, and at the moment, the medium such as compressed air or cement slurry or water in the slurry gas outlet pipe 2 flows out of the slurry gas outlet pipe 2 and enters the liquid soil in the groove. However, if the equipment such as the air compressor, the slurry pump and the like fails, so that the pressure of the compressed air, the cement slurry, the water and other media in the slurry outlet pipe 2 is lower than the pressure of the liquid soil and other media in the groove outside the sealing plate 4, at this time, the sealing plate 4 is tightly sealed with the retaining ring 3, and the liquid soil and other media in the groove outside the sealing plate 4 are prevented from entering the slurry outlet pipe 2 through the retaining ring 3, so that the slurry outlet pipe 2 and the slurry inlet pipe 1 are effectively prevented from being blocked by the groove soil.
The utility model discloses simple structure is novel, can prevent effectively that the stifled pipe of cutting box, maintains use cost low, and the bulk utilization of complete machine equipment is high, has better economic value and social.
