Description

Technical Field

[0001] This utility model relates to the field of pole manufacturing technology, and in particular to a concrete grouting device for pole molds. Background Technology

[0002] The pole mold consists of two semi-circular steel molds. During the pole processing, the tied steel reinforcement skeleton is placed smoothly into one half of the mold. Then, concrete is injected into the mold using concrete grouting equipment. After grouting, the two semi-circular steel molds are aligned, and the mold bolts or clips are tightened symmetrically. The mold is then sent to a centrifuge for the next step.

[0003] However, during the grouting process of utility pole molds, most grouting equipment tends to cause concrete to overflow from the steel mold and accumulate at the edge of the mold, requiring manual handling of the overflowing concrete, which is inconvenient. Utility Model Content

[0004] To reduce the possibility of concrete accumulating at the edge of the mold during the grouting process, this application provides a concrete grouting device for utility pole molds.

[0005] The concrete grouting equipment for utility pole molds provided in this application adopts the following technical solution:

[0006] A concrete grouting device for utility pole molds further includes a backfilling device for collecting and backfilling concrete overflowing from the utility pole molds. The grouting vehicle is slidably connected to a ground rail. The grouting vehicle is equipped with a storage hopper communicating with an extrusion chamber. The grouting vehicle is equipped with an extrusion head communicating with the extrusion chamber. A first screw is rotatably connected inside the extrusion chamber. The backfilling device includes a scraper, a recovery pipe, and a conveying component. The recovery pipe is located on the grouting vehicle. The recovery pipe has an inlet and an outlet at two points. The scraper is fixedly connected to the inlet. The conveying component is used to transport the concrete in the recovery pipe from the inlet to the outlet.

[0007] By adopting the above technical solution, through the coordinated work of the grouting truck sliding on the ground rail and the backfilling device, during the grouting process, the scraper shovels the concrete at the edge of the mold into the recycling pipe and transports it back into the mold through the conveying component. This allows for the simultaneous collection of overflowing concrete during the grouting process, reducing the possibility of concrete accumulating at the edge of the mold.

[0008] Preferably, the distance from the inlet to the outlet of the recycling pipeline gradually increases from the bottom surface of the grouting vehicle.

[0009] By adopting the above technical solution, interference with the steel reinforcement skeleton inside the pole mold is reduced. When the screw is pushed, the larger tilt angle can subject the concrete to stronger shear force, thereby reducing the possibility of concrete solidification. When the machine stops, the concrete remaining in the pipe can naturally fall back to the vicinity of the feed inlet through the tilt angle, which is convenient for centralized cleaning.

[0010] Preferably, the conveying component includes a second screw and a second motor. The second screw is coaxially and rotatably connected inside the recycling pipe, and the second motor is fixedly connected to the recycling pipe. One end of the output shaft of the second motor is coaxially and fixedly connected to the second screw.

[0011] By adopting the above technical solution, the combination of the second screw and the second motor provides stable and controllable conveying power, which can quickly transport the recycled concrete from the inlet to the outlet, reducing the possibility of concrete stagnation in the recycling pipeline.

[0012] Preferably, the grouting vehicle is equipped with a protective plate that encloses the second motor.

[0013] By adopting the above technical solution, the protective plate wraps around the second motor to prevent concrete from splashing or dust from entering the motor, reducing the probability of motor failure and ensuring the continuous and stable operation of the backfilling device.

[0014] Preferably, the scraper is located at the end furthest from the recycling pipe, and its width direction gradually narrows towards the middle section, getting closer to the recycling pipe.

[0015] By adopting the above technical solution, the "V"-shaped structure of the scraper can guide the overflowing concrete to concentrate in the middle, making it easier to introduce the concrete into the feed inlet of the recycling pipe more efficiently, reducing the spread of concrete at the edge of the mold, thereby reducing the risk of overflow.

[0016] Preferably, baffles are provided on both sides of the scraper in the width direction.

[0017] By adopting the above technical solution, baffles are set on both sides of the scraper, which can prevent overflowing concrete from flowing or splashing outwards from the scraper and confine the concrete within the collection range of the scraper. The baffles and the "V"-shaped structure of the scraper work together to form a more effective collection channel, improve recycling efficiency, reduce the time that concrete stays around the mold, and thus reduce the possibility of overflow.

[0018] Preferably, the extrusion head is provided with a guide plate, the guide plate is arc-shaped, and the distance from both ends to the middle section of the guide plate in the width direction gradually increases from the bottom surface of the grouting vehicle.

[0019] By adopting the above technical solution, the arc-shaped guide plate can guide the concrete to flow smoothly along the inner wall of the mold, avoiding direct impact of concrete on the mold and causing splashing or local accumulation.

[0020] The main technical effects of this utility model are reflected in the following aspects:

[0021] 1. This utility model, by setting up a backfilling device, works in coordination with the grouting car sliding on the ground rail. During the grouting process, the scraper scrapes the concrete at the edge of the mold into the recycling pipe and then transports it back into the mold through the conveying component. This allows for the simultaneous collection of overflowing concrete during the grouting process, reducing the possibility of concrete accumulating at the edge of the mold.

[0022] 2. By setting up a guide plate, the arc-shaped guide plate can guide the concrete to flow smoothly along the inner wall of the mold, avoiding direct impact of concrete on the mold and causing splashing or local accumulation.

[0023] 3. By setting a second screw, the combination of the second screw and the second motor provides a stable and controllable conveying power, which can quickly transport the recycled concrete from the inlet to the outlet, reducing the possibility of concrete stagnation in the recycling pipeline.

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0031] This application discloses a concrete grouting device for utility pole molds.

[0032] Reference Figure 1 and Figure 3 This embodiment of a concrete grouting device for utility pole molds further includes a backfilling device 1 for collecting and backfilling concrete overflowing from the utility pole mold. A grouting trolley 2 is slidably connected to a ground rail 3. A storage hopper 4 communicating with an extrusion chamber 5 is fixedly connected to the grouting trolley 2. An extrusion head 6 communicating with the extrusion chamber 5 is fixedly connected to the grouting trolley 2. A first screw 7 is rotatably connected inside the extrusion chamber 5. A first motor 8 is fixedly connected to the grouting trolley 2, and the first motor 8 is used to drive the rotation of the first screw 7. The backfilling device 1 includes a scraper 9, a recovery pipe 10, and a conveying component 11. The recovery pipe 10 is fixedly connected to the grouting trolley 2. The recovery pipe 10 has an inlet 12 and an outlet 13 at two points. The scraper 9 is fixedly connected to the inlet 12. The conveying component 11 is used to transport the concrete in the recovery pipe 10 from the inlet 12 to the outlet 13.

[0033] Reference Figure 4 and Figure 5 The conveying component 11 includes a second screw 14 and a second motor 15. The second screw 14 is coaxially and rotatably connected inside the recycling pipe 10. The second motor 15 is fixedly connected to the recycling pipe 10. One end of the output shaft of the second motor 15 is coaxially and fixedly connected to the second screw 14.

[0034] Reference Figure 4 and Figure 5 The combination of the second screw 14 and the second motor 15 provides stable and controllable conveying power, enabling the rapid transport of recycled concrete from the inlet 12 to the outlet 13, reducing the possibility of concrete stagnation in the recycling pipe 10. Through the coordinated operation of the grouting vehicle 2 sliding on the ground rail 3 and the backfilling device 1, during the grouting process, the scraper 9 shovels concrete from the mold edge into the recycling pipe 10 and backfills it into the mold via the conveyor 11. This allows for the simultaneous collection of overflowing concrete during the grouting process, reducing the possibility of concrete accumulation at the mold edge.

[0035] Reference Figure 2 and Figure 4The scraper 9, located away from the recovery pipe 10 at its widest end, gradually approaches the recovery pipe 10 from both sides to the middle. The "V"-shaped structure of the scraper 9 guides overflowing concrete towards the center, facilitating more efficient introduction of concrete into the inlet 12 of the recovery pipe 10, reducing the spread of concrete around the mold edge, and thus lowering the risk of overflow. Baffles 16 are fixedly connected to both sides of the scraper 9 in the width direction. These baffles 16 prevent overflowing concrete from flowing or splashing outwards from the scraper 9, confining the concrete within the collection area of ​​the scraper 9. The baffles 16, in conjunction with the "V"-shaped structure of the scraper 9, form a more efficient collection channel, improving recovery efficiency, reducing the time concrete remains around the mold, and thus lowering the possibility of overflow.

[0036] Reference Figure 1 and Figure 4 The distance from the inlet 12 to the outlet of the recovery pipe 10 gradually increases from the bottom surface of the grouting truck 2. This reduces interference with the steel reinforcement skeleton inside the pole mold during grouting. When the screw is pushed, the larger tilt angle allows the concrete to be subjected to stronger shear force, thereby reducing the possibility of concrete solidification. Furthermore, when the machine stops, the residual concrete in the pipe can naturally fall back to the vicinity of the inlet 12 through the tilt angle, making it easy to clean up.

[0037] Reference Figure 1 and Figure 2 A protective plate 17 is fixedly connected to the grouting truck 2, which encloses the second motor 15. The protective plate 17 encloses the second motor 15 to prevent concrete from splashing or dust from entering the motor, reducing the probability of motor failure and ensuring the continuous and stable operation of the backfilling device 1.

[0038] Reference Figure 2 and Figure 3 A guide plate 18 is fixedly connected to the outlet end of the extruder head 6. The guide plate 18 is arc-shaped, and the distance from both ends to the middle section of the guide plate 18 in the width direction gradually increases from the bottom surface of the grouting vehicle 2. The arc-shaped guide plate 18 can guide the concrete to flow smoothly along the inner wall of the mold, avoiding direct impact of concrete on the mold and causing splashing or local accumulation.

[0039] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
