Abstract
The utility model discloses a rotary joint structure for the conveying hose of a spraying machine, which comprises a nozzle mounting rack and a hose connection flange. One end of the nozzle mounting rack is connected with the connection shaft sleeve and the outer wall of the connection shaft sleeve is circumferentially provided with a groove. Two semicircular cards arranged in the groove can be rotated along the groove. The flange of the hose connection flange is fixedly connected with the two semicircular cards. When the rotary joint structure is connected with a concrete hose, the concrete hose can perform a revolution movement relative to a nozzle mechanism during the continuous 360-degree brushing operation of the nozzle mechanism. Therefore, the distortion and deformation of the concrete hose caused by the brushing operation of the nozzle mechanism can be avoided and the pipe blockage possibility during the pumping process is reduced. The double sealing protection of the rotary joint structure is realized through an O-shaped sealing ring and a lip-shaped sealing ring. Therefore, the leakage of concrete slurry and the pumping pressure loss are effectively prevented.
Description
Technical field
The utility model relates to the shower nozzle and defeated syndeton of expecting flexible pipe on the spraying machine, particularly relates to a kind of rotary connection structure that is used for the defeated material of spraying machine flexible pipe.
Background technology
At present spraying machine is in the tunnel during to mask sprayed mortar; Shower nozzle need be done the moving operation of continuous 360 ° of brushes, guaranteeing even ejection supporting face, exists rotation torque inevitably with the concrete flexible pipe of shower nozzle junction; Cause the hose twist distortion of junction; Thereby the increase pumping pressure, the potential danger of formation plugging, and regular distortion can shorten the application life of flexible pipe.
The utility model content
The purpose of the utility model is exactly the weak point to above-mentioned prior art, provides a kind of shower head mechanism that can effectively prevent to brush the rotational structure of concrete hose twist distortion when moving.
The purpose of the utility model realizes through following technical proposals:
A kind of rotary connection structure that is used for the defeated material of spraying machine flexible pipe; Comprise nozzle installing rack and flexible pipe adpting flange; Said nozzle installing rack one end is connected with connecting bushing, offers groove along connecting bushing outer wall circumference, and two semicircle cards are installed in the groove; And the semicircle card can rotate along groove, and the flange of flexible pipe adpting flange fastens with two semicircles and is connected.
Further, be provided with o RunddichtringO and lip-type packing between the flange of said flexible pipe adpting flange and the connecting bushing, thereby reach the effect of double seal protection, effectively prevent the loss of concrete grout seepage and pumping pressure.
Further, the other end corresponding with flange is provided with the pipe clamp flange on the said flexible pipe adpting flange.
Further, the other end relative with connecting bushing is provided with the shower nozzle flange on the said nozzle installing rack.
The beneficial effect of the utility model is: after the concrete flexible pipe is connected on this rotary connection structure; When shower head mechanism is done 360 ° of continuous moving operations of brush; The concrete flexible pipe can be done gyration with respect to shower head mechanism; Thereby prevent that the concrete flexible pipe is along with the shower nozzle brush moves and torsional deformation the possibility of plugging when having reduced pumping; And the double seal of o RunddichtringO and lip-type packing protection can effectively prevent the loss of concrete grout seepage and pumping pressure.

Fig. 2 is the three-dimensional structure diagram of flexible pipe adpting flange among Fig. 1;
Fig. 3 is the three-dimensional structure diagram of nozzle installing rack among Fig. 1;
Fig. 4 is the cross-sectional view of the utility model;
Fig. 5 is the partial enlarged drawing of I portion among Fig. 4.
The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing the utility model is further described.
Like Fig. 1-shown in Figure 5; A kind of rotary connection structure that is used for the defeated material of spraying machine flexible pipe comprises nozzle installing rack 1 and flexible pipe adpting flange 2, on the said nozzle installing rack 1 connecting bushing 1a is arranged; Offer groove 1c along connecting bushing 1a outer wall circumference; Two semicircle cards 3 are installed in the groove 1c, and semicircle card 3 can be along groove 1c rotation, the flange 2b of flexible pipe adpting flange 2 is fixedly connected through bolt 6 with two semicircle cards 3.
As shown in Figure 5, be provided with o RunddichtringO 4 and lip-type packing 5 between the flange 2b of said flexible pipe adpting flange 2 and the connecting bushing 1a, thereby reach the effect of double seal protection, effectively prevent the loss of concrete grout seepage and pumping pressure.
During installation; Shower nozzle is connected with shower nozzle flange 1b on the nozzle installing rack 1; The concrete flexible pipe is connected on the pipe clamp flange 2a of flexible pipe adpting flange 2 through pipe clamp; Flexible pipe adpting flange 2 is installed on the connecting bushing 1a of nozzle installing rack 1 through flange 2b; And two the semicircle cards 3 and the contact surface between the connecting bushing 1a that are fixed on the flange 2b form the axial limiting structure, make flexible pipe adpting flange 2 do only freely turn round, prevent that shower head mechanism from brushing the purpose that the concrete hose twist is out of shape when moving thereby reach.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
