Detailed Description
The utility model is further described below with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical aspects of the present utility model, and are not intended to limit the scope of the present utility model.
Examples: referring to fig. 1, in a normal pressure cutterhead shield machine, workers can enter the cutterhead 1, and maintenance is performed on cutters of the cutterhead 1. The rotation of the cutterhead 1 drives the pipeline inside the cutterhead 1 to rotate simultaneously, and at this time, the pipeline inside the cutterhead 1 needs to be fixed and restrained.
Referring to fig. 2-5, a pipeline limiting device applied to a shield tunneling machine cutterhead comprises a base 4, a clamping plate 2 fixed on the base 4 and a clamping plate 3 sliding on the base 4, wherein a screw rod 8 penetrates through the clamping plate 2, the screw rod 8 further penetrates through the clamping plate 3 and is in threaded connection with a nut 9, a spring 10 is sleeved on the screw rod 8, and two ends of the spring 10 respectively abut against the clamping plate 2 and the clamping plate 3. The butt joint of splint 3 and cardboard 2 has seted up semicircle type draw-in groove 11, and draw-in groove 11 sets up relatively and can synthesize circular or oval, and pipeline 14 is in draw-in groove 11. A magnet 5 is arranged below the base 4, and the magnet 5 is used for being adsorbed on the cutterhead 1.
Referring to fig. 2-5, when the screw 8 or the nut 9 is rotated such that the screw 8 and the nut 9 are rotated relative to each other, the nut 9 abuts the clamping plate 3 to approach the clamping plate 2, thereby clamping the pipeline 14. When the screw rod 8 or the nut 9 is reversely rotated, the clamping plate 3 is gradually used for clamping the plate 2 under the action of the spring 10, so that the pipeline 14 is loosened. When the nut 9 is completely disengaged from the screw 8, the clamping plate 3 can now be completely removed. This arrangement allows the line 14 to pass directly above into the clamping groove 11 without axial penetration from the clamping groove 11. When the shield machine works underground, the shield machine is prevented from being stopped to remove the pipeline and then is installed with the clamping plate 3 and the clamping plate 2, and the pipeline 14 can be directly installed in the clamping groove 11 under the working condition that the two ends of the pipeline 14 are not removed.
Referring to fig. 2-5, the clamping plate 3 and the clamping plate 2 are in a U shape, the clamping plate 3 is attached to the inner side wall of the clamping plate 2, and is inserted into the clamping plate 2 in the process of clamping the pipeline 14. The base 4 is provided with L-shaped connecting plates 6, two connecting plates 6 are arranged, the vertical section of each connecting plate 6 is attached to the outer side wall of each clamping plate 2, and the connecting plates 6 are simultaneously and detachably fixedly connected with the floor and the clamping plates 2 through bolts. Set up deflector 7 between connecting plate 6 and the splint 3, the gap between splint 3 and the connecting plate 6 is filled up to deflector 7, and deflector 7 passes through spacing nail 13 and connecting plate 6 fixed connection, has seted up the spacing groove on the splint 3, and spacing nail 13 slides and sets up in the spacing groove, ensures so that splint 3 can only slide to cardboard 2 direction by the level, and can not break away from base 4.
Referring to fig. 2-5, a rubber pad (not shown in the drawings) is sleeved on the side wall of the clamping groove 11, the section of the rubber pad is concave, and the rubber pad is clamped in the clamping groove 11, so that the clamping force of the clamping plate 3 and the clamping plate 2 can be prevented from shearing damage to the pipeline 14.
Referring to fig. 2-5, the base 4 is threadably connected to the cap 12, and the magnet 5 is positioned within the cap 12 and the base 4. The magnet 5 is prevented from being adsorbed on the cutterhead 1 when the base 4 is prevented from being dismounted.
The implementation principle of the embodiment is as follows: the base 4 is used for fixing any position of the cutterhead 1 through the magnet 5, further placing the pipeline 14 in the clamping groove 11, driving the clamping plate 3 to be close to the clamping plate 2 through the rotary screw rod 8 or the screw cap 9, and clamping the pipeline 14, so that the pipeline 14 cannot swing in the rotating process of the cutterhead 1, and further loosening and damage of the pipeline 14 are avoided.
The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that modifications and variations could be made by those skilled in the art without departing from the technical principles of the present utility model, and such modifications and variations should also be regarded as being within the scope of the utility model.
