The upper end of the mounting tube is pivotally connected to the feed tube 12 through the mounting station 16 and the lower end is connected to the feed tube 3 through the base 4. The rotary table 10 is connected with the mounting table 16 through a thrust bearing, and the cross rod 11 is fixedly connected with the rotary table 10.

The conveying pipe 12 is a steel pipe 7, is arranged on the cross rod 11 and is connected with the cross rod 11. For the sake of convenience of distinction, the end of the cross bar 11 where the conveying pipe 12 is provided is a first end, and the other end is a second end. The part of the feed pipe 12 near the first end is bent downward for connection to the tapping pipe 2.

Referring to fig. 4, the discharging pipe 2 includes a steel pipe 7 and a rubber pipe 6, wherein the steel pipe 7 is horizontally disposed, one end of the steel pipe is rotatably connected to the conveying pipe 12, and the other end of the steel pipe is connected to the rubber pipe 6.

The crossbar 11 is provided at a first end with a mounting assembly 13 for connecting the tapping pipe 2 with the delivery pipe 12. Specifically, the mounting assembly 13 includes an upper end connection ring 22, a lower end connection ring 23 and three connection rods; the upper end connecting ring 22 and the lower end connecting ring 23 are coaxially arranged, and the upper end connecting ring 22 is arranged above the lower end connecting ring 23 and is fixedly connected through three vertically arranged connecting rods.

The conveying pipe 12 comprises a horizontal section and a vertical section which are connected with each other, and a limiting ring is arranged on the vertical section; the upper end connecting ring 22 is sleeved on the vertical section and is rotatably matched with the upper surface of the limiting ring.

One end of the discharge pipe 2 is provided with a vertical cylinder 14, the lower end of the vertical cylinder 14 is closed, and the upper end is provided with an annular groove 25; the lower end connecting ring 23 is rotatably sleeved in the annular groove 25; the lower end of the vertical section is inserted into the vertical cylinder 14; the delivery tube 12 is connected to the wall of the vertical column 14 and communicates with the internal bore of the vertical column 14.

The mounting assembly 13 described above not only makes possible a rotatable connection of the tapping pipe 2 and the delivery pipe 12, but also makes it possible to receive the weight of the tapping pipe 2. In addition, the whole structure is simpler, and the rotating part can be effectively prevented from being blocked.

For the convenience of assembly and disassembly, the upper end connecting ring 22 and the lower end connecting ring 23 are not integrally formed, but are formed by detachably connecting three arc-shaped plates. Specifically, the upper end connecting ring 22 comprises three upper end arc-shaped plates which are detachably connected end to end, and the lower end connecting ring 23 comprises three lower end arc-shaped plates which are detachably connected end to end; the upper end arc-shaped plate is connected with the corresponding lower end arc-shaped plate through a connecting rod.

When in specific use, the cross bar 11 is rotated to a preset position; then, the discharge pipe 2 is rotated according to the distance from the construction area to the support frame 1, so that a discharge hole of the discharge pipe 2 can be exactly aligned with the construction area; and finally, starting the delivery pump.

Referring to fig. 1, when the delivery pipe 12 delivers concrete, the first end of the cross bar 11 is heavy, so that the support frame 1 is easy to topple; especially when discharging pipe 2 is greater than 90 with the angle of horizontal pole 11, the arm of force extension of the first end of horizontal pole 11 for the moment that the first end of horizontal pole 11 received is bigger, and the overall stability of support frame 1 is worse. Thus, the second end of the concrete equipment rail 11 is also provided with a counterweight arrangement.

Specifically, the counter weight device includes frame 8, lead screw 20, nut 21, counter weight and motor 9, and wherein frame 8 extends along the length direction of horizontal pole 11, including two bar boards, two bar boards and 11 second end connections of horizontal pole to two relative interval settings form the mounting groove. The screw rod 20 is arranged in the mounting groove and is rotatably connected with two ends of the frame 8, and the nut 21 is sleeved on the screw rod 20. The nut 21 is rectangular and when the screw 20 is rotated, its free end is restrained by the frame 8 so as to move along the screw 20. The motor 9 is arranged at the end part of the frame 8 and is connected with the screw rod 20 for driving the screw rod 20 to rotate. The weight is suspended below the nut 21 by a connecting string and can move along the axial direction of the screw rod 20 along with the nut 21.

Further, the concrete pouring equipment further comprises a controller and an angle sensor, wherein the angle sensor is mounted at the first end of the cross rod 11 and used for detecting the rotation angle of the material pipe 2; when the free end of the discharge pipe 2 rotates towards the direction far away from the support frame 1, the angle between the free end and the cross rod 11 is increased; otherwise, it is decreased. The controller is electrically connected with the angle sensor and the motor 9, and the controller can receive signals of the angle sensor and control the motor 9 to work.

When the angle between the discharge pipe 2 and the cross rod 11 is increased, the controller controls the motor 9 to rotate forward, so that the nut 21 drives the counterweight to move a corresponding distance towards the direction close to the second end of the cross rod 11; thereby increasing the moment at the second end of the cross bar 11 and preventing the first end of the support stand 1 from falling down.

When the angle between the discharge pipe 2 and the cross rod 11 is reduced, the controller controls the motor 9 to rotate reversely, so that the nut 21 moves a corresponding distance in the direction away from the second end of the cross rod 11, the moment of the second end of the cross rod 11 is correspondingly reduced, and the second end of the support frame 1 is prevented from toppling downwards.

In addition, the moving distance of the nut 21 is positively correlated with the angle change of the discharge pipe 2 and the cross rod 11; that is, the greater the change in the angle, the greater the number of turns of the screw 20 and the greater the moving distance of the nut 21.

The controller adopts a single chip microcomputer or a PLC, and the controller and the sensor can be directly purchased and are not described any more.

It should be noted that, in other embodiments, the counterweight device may not be provided, or the controller and the angle sensor may not be provided; the worker can control the motor 9 to work according to experience.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
