[0002] Prestressed high-strength concrete pipe piles, as a cement product, are widely used in various infrastructure projects. Concrete pumping is an important production link of concrete pipe piles. Its function is to inject the mixed concrete into the mold during the production process of concrete pipe piles and confirm the volume of injected concrete by metering.

[0003] A Chinese patent document with publication number CN215150312U discloses an automatically height-adjusting metering flat cart for pipe pile mold pumping, comprising a weighing platform, a sensor, and a control system. Several weighing platforms are connected by connecting steel frames, and the pipe pile mold is supported on several weighing platforms. The weighing platform comprises a weighing part and a height adjustment part. The weighing part is used to measure the weight of the pipe mold; the height adjustment part is used to change the center height of the pipe pile mold, the sensor is used to detect the parameters of the pipe pile mold, and the control system controls the height adjustment part according to the parameters detected by the sensor to match the center of the pipe pile mold with the height of the pump pipe. The trolley height can be automatically adjusted according to the center height of different pipe pile molds to make the pipe pile mold consistent with the center of the pump pipe.

[0004] The above adjustment method uses the method of adjusting the position of the pipe pile mold for adjustment. Due to the large size of the pipe pile mold, the steps are relatively cumbersome, time-consuming and labor-intensive when adjusting. In addition, it is necessary to lift it up first and then raise the bottom to adjust the position. The adjustment height is related to the height of the step block, resulting in low adjustment accuracy. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] like Figure 1-Figure 5 The pump pipe support and adjustment device for a pipe pile mold pumping shown in the figure is arranged on the opposite side of the pipe pile mold metering flat car. The pipe pile mold metering flat car includes a plurality of weighing platforms 10. The weighing platforms 10 are arranged on a bottom crossbeam 16 that slides along the guide rail. The bottom crossbeam 16 is provided with a roller that moves on the guide rail with a limited position. The bottom crossbeam 16 moves back and forth along the guide rail through a transmission belt (not shown in the figure) driven by a motor arranged at its bottom. The pump pipe support and adjustment device includes a rear end bracket 1, a first trolley 2, a second trolley 3, and a front end bracket 4 arranged in sequence along the guide rail. The end bracket 1 is fixedly set on the foundation, and the first trolley 2, the second trolley 3, and the front end bracket 4 are all moved on the guide rail by the roller limit provided at the bottom. The first trolley 2 and the rear end bracket 1, and the first trolley 2 and the second trolley 3 are connected by an iron chain (not shown in the figure). The top frame 11 of the rear end bracket 1, the first trolley 2, the second trolley 3, and the front end bracket 4 are all provided with auxiliary rollers 6 for supporting the pump pipe 5. By using the movable first trolley 2, the second trolley 3, and the front end bracket 4 as support points, the pump pipe 5 can be supported more flexibly.

[0024] The front bracket 4 is connected to the pipe pile mold metering flat car through a connecting plate 12. A visual sensor is provided on the front bracket 4. When the pipe pile mold metering flat car drives the pipe pile mold 7 to move along the guide rail, it can drive the front bracket 4 to move. The front bracket 4 moves and hits the second trolley 3. After the front bracket 4 hits the second trolley 3, the two move together and continue to collide with the first trolley 2. The first trolley 2 is provided with an anti-collision block 8 to reduce the buffer. Then the three move together to the end of the guide rail. At this time, the pump pipe 5 is completed. It is fully extended into the pipe pile mold 7, and when the pipe pile mold metering flat car drives the pipe pile mold 7 to retreat, the iron chains between the first trolley 2 and the rear end bracket 1 and between the first trolley 2 and the second trolley 3 are used to pull, and several supporting points are dispersed, so that the pump pipe 5 can be supported more flexibly. A buckle 9 that can be engaged with the front end bracket 4 is provided on the second trolley 3. The buckle 9 can separate the front end bracket 4 from the second trolley 3 when the pipe pile mold 7 retreats, so that the pipe pile mold 7 can be better separated from the pump pipe 5.

[0025] An adjusting device for driving the auxiliary roller 6 to move up and down is provided on the top frame 11. The adjusting device includes an adjusting bolt 13 threadedly connected to the top frame 11. The adjusting bolt 13 is vertically arranged. Both ends of the central axis of the auxiliary roller 6 are mounted on the top of the adjusting bolt 13. The auxiliary roller 6 is rotatably connected to the central axis through the bearing. By turning the adjusting bolt 13 to move up and down, the auxiliary roller 6 is driven to move up and down, thereby realizing the height adjustment of the pump pipe 5.

[0026] In addition, in order to be more automated, the adjustment device is set to a screw rod 14 driven by a motor, and a screw slider 15 is connected to the screw rod 14 for transmission. The two ends of the central axis of the auxiliary roller 6 are socketed on the screw slider 15. The motor drives the screw rod 14 to rotate and then drives the screw slider 15 to move up and down, thereby realizing the up and down adjustment of the auxiliary roller 6, so that the central axis of the pipe pile mold 7 on the pipe pile mold metering flat car is concentric with the central axis of the pump pipe 5.

[0027] The utility model mentions a pump pipe support and adjustment device for pipe pile mold pumping, which adopts a PLC controller to realize automatic control. When the pipe pile mold 7 is placed on the pipe pile mold metering flat car, the visual sensor on the front end bracket 4 can obtain the image of the pipe pile mold 7, and calculate the difference between the central axis of the pump pipe 5 and the central axis of the pipe pile mold 7 through the controller. Then the driving motor drives the screw slider 15 of the adjustment device to move up and down, and adjusts the up and down position of the auxiliary roller 6 so that the central axis of the pipe pile mold 7 is concentric with the central axis of the pump pipe 5. Then the pipe pile mold 7 moves forward and drives the front end bracket 4 to move along the guide rail and move it with the second trolley 3. The buckle 9 provided on the second trolley 3 is hooked on the front end bracket 4. The second trolley 3 continues to move and collides with the first trolley 2. The anti-collision block 8 can play a buffering role. After that, the first trolley 2 When it moves to the end of the guide rail, the first trolley 2, the second trolley 3 and the front end bracket 4 are finally close together. During the movement, the pump pipe 5 continues to fill concrete into the pipe pile mold 7 until the pump pipe 5 completely enters the pipe pile mold 7. When the pumping is completed, the pipe pile mold 7 moves backward, and the front end bracket 4 moves backward, driving the second trolley 3 to move synchronously. While moving, the first trolley 2 is driven to move by the iron chain. When the iron chains between the first trolley 2 and the rear end bracket 1 and between the second trolley 3 and the first trolley 2 are straightened, the front end bracket 4 continues to move, thereby generating tension between the front end bracket 4 and the second trolley 3. The buckle 9 is unhooked from the front end bracket 4 under the action of the force, and the second trolley 2 will stop moving. Finally, the first trolley 2, the second trolley 3, the rear end bracket 1 and the front end bracket 4 are spaced apart, which can provide good support for the pump pipe 5.

[0028] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements to the technical solution of the present invention made by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention. The technical content sought to be protected by the present invention is fully set forth in the claims.
