The working process of the hose fastening system and the material distribution machine in the present application is described as follows:

when the distribution machine is in a running state, the stop valve 146 is closed, and the compressed air in the air storage device 144 cannot enter the air supply pipeline 142 arranged in the turret and the arm support 30, so that the problem that the compressed air in the air storage device 144 leaks due to the rupture of the air supply pipeline 142 is solved.

After the cloth is mechanically switched to the pumping state, the stop valve 146 is opened to let the compressed air in the air storage device 144 enter the air supply pipeline 142, and at this time, the pressure value in the air supply pipeline 142 should be adjusted to a proper pressure value by the pressure adjusting valve 148, so as to avoid the problem of insufficient holding force of the air supply device 14 due to air leakage of the air path caused by too high pressure or too low pressure. Before the pumping operation is started, the electromagnetic on-off valve 149 should be opened remotely to allow the compressed air to enter the air supply line 142 on the boom 30 and the clasping device 12 in sequence, and at this time, it is required to check whether the clasping device 12 at the hose 100 is working normally. After the inspection is completed, the electromagnetic on-off valve 149 needs to be closed remotely, and the compressed air in the air storage device 144 will not enter the air supply pipeline 142 on the boom 30.

In the process of pumping operation, if the material distribution point needs to be changed, that is, the boom 30 needs to be moved, at this time, in order to prevent the concrete 90 in the delivery pipe 20 from splashing, at this time, only the electromagnetic on-off valve 149 needs to be opened remotely through a button on a remote controller (connected with the electromagnetic on-off valve 149 for controlling the on-off of the electromagnetic on-off valve 149), at this time, compressed air enters the clasping device 12 through the air supply pipeline 142 on the boom 30, at this time, the deformation cavity 122 of the clasping device 12 expands after being filled with air, so that the hose 100 is clasped, the hose 100 is radially contracted and closed, at this time, the residual concrete 90 in the delivery pipe 20 is collected in the hose 100. When the pressure of the clasping device 12 reaches the pressure value set by the one-way constant pressure valve 141, the compressed air will not inflate into the clasping device 12, the clasping device 12 is in the pressure maintaining state, and the redundant compressed air can be exhausted from the one-way exhaust valve 145.

When the arm support 30 is moved to the preset position and the material distribution operation needs to be performed again, the electromagnetic on-off valve 149 needs to be closed on the remote controller, the clasping device 12 is restored to the normal shape under the action of the self weight of the concrete 90, and redundant compressed air is exhausted from the one-way exhaust valve 145.

In the present application, the manual ball valve, the pressure regulating valve 148 and the electromagnetic on-off valve 149 are all disposed in a cavity of the left-side turret of the material distribution machine, and the gas storage device 144 is a chassis gas tank of the material distribution machine. The third connecting port 1416 of the one-way constant pressure valve 141 is communicated with the clasping device 12 through the exhaust pipe 147, and when the output pressure of the second connecting port 1414 of the one-way constant pressure valve 141 is greater than a preset value, the third connecting port 1416 is opened, and the compressed air overflowing from the clasping device 12 can be exhausted from the one-way exhaust valve 145 through the exhaust pipe 147. The one-way constant pressure valve 141 regulates the air pressure inside the clasping means 12 while controlling the compressed air overflowed inside the clasping means 12 to be discharged from the one-way discharge valve 145.

The hose enclasping system and the cloth machine in the application have the following advantages:

1. the hose clasping system 10 is simple to operate and convenient to use, can be operated through a remote controller, does not need to disassemble and assemble any part in the using process, and can be used only by closing the electromagnetic on-off valve 149 through the remote controller;

2. the safety of the hose clasping system 10 is high, and the hose clasping system 10 is provided with safety protection devices such as a pressure regulating valve 148, a manual ball valve and a safety protection rope 50, so that the problems that the air supply pipeline 142 bursts and the clasping device 12 falls to hurt people due to air leakage and overhigh air pressure of the air supply pipeline 142 can be solved. Meanwhile, due to the remote operation, the operation at the tail end hose is not needed, so that the problem that the tail end hose hurts people due to misoperation can be avoided;

3. the distributing machine is safe and environment-friendly, and the tail end hose of the distributing machine can effectively collect the residual concrete 90 in the conveying pipe 20, so that the concrete 90 is prevented from splashing and polluting the distributing machine and the surrounding environment.

From the above description, it can be seen that the inner wall surface of the hose 100 deforms and fits due to the holding force applied to the hose 100 by the holding device 12. This interrupts the line of the hose 100, and the medium cannot pass through the hose 100, so that the hose 100 is shut off by the clasping device 12. The air supply device 14 controls the operation of the clasping device 12 by pressing the clasping device 12, thereby indirectly controlling the turning-off of the hose 100. The air supply device 14 can be used for remotely controlling the switching-off of the hose 100 so as to prevent the concrete 90 from splashing from the hose 100, so that a mechanical stop device does not need to be arranged on the periphery of the hose 100 as in the related art, and the mechanical stop device is operated in a manual control mode to control the switching-off of the hose 100, so that the problems of unsafe operation of field personnel and inconvenient operation of the field caused by the mode are avoided, and the pumping operation on the field can be smoothly completed.
