Abstract
The invention discloses a rotary connecting structure for a feed delivery hose of a jet plane. The rotary connecting structure comprises a jet nozzle mounting rack and a hose connecting flange, wherein a connecting shaft sleeve is connected to one end of the jet nozzle mounting rack; a groove is formed along the periphery of the outer wall of the connecting shaft sleeve; two semicircular clamps are mounted in the groove and can rotate along the groove; and a flange plate of the hose connecting flange is fixedly connected with the two semicircular clamps. After a concrete hose is connected to the rotary connecting structure, when a jet head mechanism performs a continuous 360-degree brush operation, the concrete hose can perform a rotary movement relative to the jet head mechanism, so as to prevent the concrete hose from moving with the jet head and distorting, and further reduce the possibility that the pipe is blocked during pumping; and through adoption of dual seal protection of an O-shaped seal ring and a lip-type seal ring, the leakage of concrete grout and the pressure loss of pumping can be effectively prevented.
Description
Technical field
The present invention relates to shower nozzle on spraying machine and the syndeton of conveying flexible pipe, particularly relate to a kind of rotary connection structure for spraying machine conveying flexible pipe.
Background technology
At present spraying machine is in tunnel during to mask sprayed mortar, shower nozzle need be done continuous 360 ° and swipe operation, to guarantee even ejection supporting face, inevitably exist rotation torque with the concrete flexible pipe of shower nozzle junction, cause the hose twist distortion of junction, thereby increase pumping pressure, the potential danger of formation plugging, and regular distortion meeting shortens the application life of flexible pipe.
Summary of the invention
Object of the present invention is exactly for above-mentioned the deficiencies in the prior art part, and a kind of rotational structure of concrete hose twist distortion can effectively prevent that shower head mechanism from swiping time is provided.
Object of the present invention realizes by following technical proposals:
A kind of rotary connection structure for spraying machine conveying flexible pipe, comprise nozzle installing rack and flexible pipe adpting flange, described nozzle installing rack one end is connected with connecting bushing, along connecting bushing outer wall circumference, offer groove, two semicircle cards are installed in groove, and semicircle card can rotate along groove, the flange of flexible pipe adpting flange fastens and is connected with two semicircles.
Further, between the flange of described flexible pipe adpting flange and connecting bushing, be provided with o RunddichtringO and lip-type packing, thereby reach the effect of double seal protection, effectively prevent concrete grout seepage and pumping pressure loss.
Further, on described flexible pipe adpting flange, the other end corresponding with flange is provided with pipe clamp flange.
Further, on described nozzle installing rack, the other end relative with connecting bushing is provided with shower nozzle flange.
Beneficial effect of the present invention is: after concrete flexible pipe is connected on this rotary connection structure, at shower head mechanism, do continuous 360 ° while swiping operation, concrete flexible pipe can be done gyration with respect to shower head mechanism, thereby prevent that concrete flexible pipe is along with shower nozzle swipes and torsional deformation, the possibility of plugging while having reduced pumping; And the double seal of o RunddichtringO and lip-type packing protection, can effectively prevent concrete grout seepage and pumping pressure loss.

Fig. 2 is the three-dimensional structure diagram of flexible pipe adpting flange in Fig. 1;
Fig. 3 is the three-dimensional structure diagram of nozzle installing rack in Fig. 1;
Fig. 4 is cross-sectional view of the present invention;
Fig. 5 is the partial enlarged drawing of I portion in Fig. 4.
The specific embodiment
Below in conjunction with specific embodiments and the drawings, the present invention is further illustrated.
As Figure 1-Figure 5, a kind of rotary connection structure for spraying machine conveying flexible pipe, comprise nozzle installing rack 1 and flexible pipe adpting flange 2, on described nozzle installing rack 1, there is connecting bushing 1a, along connecting bushing 1a outer wall circumference, offer groove 1c, two semicircle cards 3 are installed in groove 1c, and semicircle card 3 can be along groove 1c rotation, the flange 2b of flexible pipe adpting flange 2 is fixedly connected with by bolt 6 with two semicircle cards 3.
As shown in Figure 5, between the flange 2b of described flexible pipe adpting flange 2 and connecting bushing 1a, be provided with o RunddichtringO 4 and lip-type packing 5, thereby reach the effect of double seal protection, effectively prevent concrete grout seepage and pumping pressure loss.
During installation, shower nozzle is connected with the shower nozzle flange 1b on nozzle installing rack 1, concrete flexible pipe is connected on the pipe clamp flange 2a of flexible pipe adpting flange 2 by pipe clamp, flexible pipe adpting flange 2 is arranged on the connecting bushing 1a of nozzle installing rack 1 by flange 2b, and two the semicircle cards 3 and the contact surface between connecting bushing 1a that are fixed on flange 2b form axial limit structure, make flexible pipe adpting flange 2 do only freely to turn round, thereby reach the object of concrete hose twist distortion while preventing that shower head mechanism from swiping.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
