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 the 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 the tunnel during to mask sprayed mortar, shower nozzle need be done continuous 360 ° and swipe operation, to guarantee even ejection supporting face, exist inevitably rotation torque 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.
Summary of the invention
Purpose 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 prevent effectively that shower head mechanism from swiping the time is provided.
Purpose 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, offer groove along connecting bushing outer wall circumference, 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 described 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 described flexible pipe adpting flange.
Further, the other end relative with connecting bushing is provided with the shower nozzle flange on the described nozzle installing rack.
Beneficial effect of the present invention is: after the concrete flexible pipe is connected on this rotary connection structure, do continuous 360 ° when swiping operation at shower head mechanism, the concrete flexible pipe can be done gyration with respect to shower head mechanism, thereby prevent the concrete flexible pipe along with shower nozzle swipes 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.

The specific embodiment
The present invention is further illustrated below in conjunction with specific embodiments and the drawings.
Such as Fig. 1-shown in 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 the described 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 with by 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 described 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 by pipe clamp, flexible pipe adpting flange 2 is installed on the connecting bushing 1a of nozzle installing rack 1 by 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 axial limit structure, make flexible pipe adpting flange 2 do only freely to turn round, thereby reach the purpose of concrete hose twist distortion when preventing that shower head mechanism from swiping.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
