Examples:

referring to fig. 1, the present embodiment provides a concrete pouring apparatus for pouring concrete into a construction area; the concrete equipment comprises a support frame 1, a cross rod 11 and a conveying assembly. The cross rod 11 is horizontally arranged, and the middle part of the cross rod is rotatably connected with the upper end of the support frame 1; the conveying assembly is arranged on the support frame 1 and comprises a feeding pipe 3, a conveying pipe 12 and a discharging pipe 2 which are connected in sequence; the inlet pipe 3 is used for being connected with the concrete delivery pump, and the discharging pipe 2 is used for pouring concrete in the construction area.

Referring to fig. 2 and 3, the support frame 1 includes a mounting seat and three support rods, wherein the upper ends of the three support rods are connected with the bottom of the mounting seat. The mounting seat comprises a base 4, a mounting table 16, a mounting pipe, a turntable 10 and three fixing rods 15, wherein the base 4 is a triangular seat plate, the mounting table 16 is a circular plate, and the mounting table 16 is connected with the base 4 through the three fixing rods 15. The upper end of the mounting tube passes through the mounting table 16 to be rotatably connected with the conveying tube 12, and the lower end passes through the base 4 to be connected with the feeding tube 3. The turntable 10 is connected with the mounting table 16 through a thrust bearing, and the cross rod 11 is fixedly connected with the turntable 10.

The conveying pipe 12 is a steel pipe, is arranged on the cross rod 11, and is connected with the cross rod 11. For convenience of distinction, the cross bar 11 is provided with a conveying pipe 12 having a first end and a second end. The portion of the delivery pipe 12 near the first end is bent downwards for connection with the tapping pipe 2.

Referring to fig. 4, the discharging pipe 2 includes a steel pipe 5 and a rubber pipe 6, wherein the steel pipe 5 is horizontally disposed, one end of the steel pipe is rotatably connected with the conveying pipe 12, and the other end of the steel pipe is connected with the rubber pipe 6.

The first end of the cross bar 11 is provided with a mounting assembly 13 for connecting the tapping pipe 2 with the transfer pipe 12. Specifically, the mounting assembly 13 includes an upper end connecting ring 22, a lower end connecting ring 23, and three connecting 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 in rotatable fit with the upper surface of the limiting ring.

One end of the discharging pipe 2 is provided with a vertical cylinder 14, the lower end of the vertical cylinder 14 is closed, and the upper end of the vertical cylinder 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 spliced in the vertical cylinder 14; the delivery tube 12 is connected to the wall of the vertical tube 14 and communicates with the bore of the vertical tube 14.

The above-described mounting assembly 13 not only achieves a rotatable connection of the tapping pipe 2 and the delivery pipe 12, but also enables it to take up the weight of the tapping pipe 2. In addition, the whole structure is simple, and the locking of the rotating part can be effectively prevented.

For easy assembly and disassembly, the upper end connecting ring 22 and the lower end connecting ring 23 are not integrally formed, but are detachably connected by three arc plates. Specifically, the upper end connecting ring 22 includes three upper end arcuate plates detachably connected end to end, and the lower end connecting ring 23 includes three lower end arcuate plates detachably connected end to end; the upper end arc plate is connected with the corresponding lower end arc plate through a connecting rod.

When the device is particularly used, the cross bar 11 is rotated to a preset position; then, the discharging pipe 2 is rotated according to the distance from the construction area to the support frame 1, so that the discharging hole of the discharging pipe 2 can be just aligned to the construction area; and finally, starting the conveying pump.

Referring to fig. 1, when the conveying pipe 12 conveys concrete, the weight of the first end of the cross bar 11 is relatively heavy, so that the supporting frame 1 is easy to topple over; especially when the angle of discharging pipe 2 and horizontal pole 11 is greater than 90, the arm of force of horizontal pole 11 first end is prolonged for the moment that horizontal pole 11 first end received is bigger, and support frame 1's overall stability is worse. Thus, the second end of the concrete plant cross bar 11 is also provided with a counterweight.

Specifically, the counterweight device comprises a frame 8, a screw rod, a nut 21, a counterweight 7 and a motor 9, wherein the frame 8 extends along the length direction of the cross rod 11 and comprises two strip-shaped plates, the two strip-shaped plates are connected with the second end of the cross rod 11, and the two strip-shaped plates are oppositely arranged at intervals to form a mounting groove. The screw rod 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. The nut 21 has a rectangular shape, and when the screw is rotated, its rotation free end is restricted by the frame 8 so as to move along the screw. The motor 9 is arranged at the end part of the frame 8 and is connected with the screw rod for driving the screw rod to rotate. The counterweight is suspended below the nut 21 by a connecting rope and can move along the axial direction of the screw rod along with the nut 21.

Further, the concrete pouring equipment further comprises a controller and an angle sensor, wherein the angle sensor is arranged at the first end of the cross rod 11 and is used for detecting the rotation angle of the discharging pipe 2; when the free end of the discharging pipe 2 rotates in a direction away from the supporting frame 1, the angle between the discharging pipe and the cross rod 11 is increased; and conversely, the number is reduced. The controller is electrically connected with the angle sensor and the motor 9, and can receive the signals of the angle sensor and control the motor 9 to work.

When the angle between the discharging pipe 2 and the cross bar 11 is increased, the controller controls the motor 9 to rotate positively, so that the nut 21 moves with the counterweight for a corresponding distance towards the direction approaching the second end of the cross bar 11; so that the moment of the second end of the crossbar 11 increases and the first end of the support bracket 1 is prevented from falling down.

When the angle between the discharging 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 a direction away from the second end of the cross rod 11, the moment at the second end of the cross rod 11 is correspondingly reduced, and the second end of the support frame 1 is prevented from falling down.

In addition, the moving distance of the nut 21 is positively correlated with the angle change of the discharging pipe 2 and the cross rod 11; that is, as the above-mentioned angle change is larger, the number of turns of the screw is larger, and the moving distance of the nut 21 is larger.

The controller adopts a singlechip or a PLC, and the controller and the sensor can be directly purchased and are not described.

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 of the preferred embodiments of the present invention and is not intended to limit the present invention, and various modifications and variations may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
