Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of commercial concrete pouring equipment, and in particular to a commercial concrete pouring material placing rod that can rotate 360 degrees. Background Technology
[0002] In the process of commercial concrete pouring, the placing boom is a key piece of equipment, and its performance directly affects construction efficiency, quality, and cost.
[0003] Traditional concrete placing booms consist of a rubber hose installed at the end of the pumped steel pipe. However, the rubber hose has significant limitations in rotational flexibility, making it difficult to meet the increasingly complex construction needs of modern building projects. Traditional placing booms typically rely on manual operation, requiring highly experienced operators. In complex construction environments, manual operation struggles to guarantee the accuracy and uniformity of the concrete placement, easily leading to areas where the concrete is too thick or too thin, affecting the stability and quality of the building structure. Furthermore, manual operation is slow to react to unexpected situations and cannot adjust placing parameters in a timely manner, further increasing construction risks. For example, during bridge pier pouring, human error can cause significant thickness deviations in some areas, necessitating rework, wasting materials and time, and severely impacting project progress.
[0004] To address the shortcomings of the aforementioned technologies, we propose a commercial concrete pouring placing boom that can rotate 360 degrees. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a 360-degree rotating concrete pouring placing bar.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A 360-degree rotatable concrete pouring placing boom includes a concrete pumping steel pipe, a rotating drum rotatably mounted at the lower end of the concrete pumping steel pipe, a protective cover sleeved on the outer side of the connection between the concrete pumping steel pipe and the rotating drum, and an internal steering assembly inside the protective cover; the internal steering assembly includes a mounting plate base, the mounting plate base is fixedly mounted on the outer wall of the concrete pumping steel pipe and a second motor is fixedly mounted on the mounting plate base, a gear is fixedly mounted on the output end of the second motor, a gear ring is fixedly mounted on the outer wall of the rotating drum, the gear meshes with the gear ring, the protective cover is screwed onto the outer wall of the concrete pumping steel pipe, and the rotating drum rotates through the protective cover.
[0008] Furthermore, a controller and a wireless signal transmission antenna are fixedly installed on the outer wall of the protective cover.
[0009] Furthermore, a first annular groove and a second annular groove are formed on the outer wall of the commercial concrete pumping steel pipe, and a rubber ring is fitted inside the second annular groove.
[0010] Furthermore, a snap-fit rotating ring is rotatably provided inside the second annular groove, and a plurality of balls are embedded inside the snap-fit rotating ring. The snap-fit rotating ring is screwed onto the inner wall of the rotating cylinder.
[0011] Furthermore, a rubber corrugated pipe is fixedly connected to the lower end of the rotating drum, and a metal pipe opening is fixedly installed at the lower end of the rubber corrugated pipe.
[0012] Furthermore, the rubber corrugated pipe is symmetrically provided with support plates on both sides, the metal pipe opening is rotatably installed on the inner side of the two support plates, and a first motor is fixedly installed on the outer wall of the support plate. The output end of the first motor passes through to the inner side of the support plate and is fixedly connected to the side wall of the metal pipe opening.
[0013] Furthermore, the support plate is fixedly installed at the lower end of the rotating drum.
[0014] Compared with related technologies, the 360-degree rotating concrete placement rod proposed in this utility model has the following beneficial effects:
[0015] In this invention, a 360-degree rotatable concrete pouring boom is described. A rotating drum is installed at the end of the concrete pumping steel pipe, and an internal steering assembly is located between the drum and the pipe. Rotating the second motor inside the protective cover drives the drum to rotate 360 degrees without dead angles, thereby causing the metal pipe outlet installed below the drum to rotate horizontally without dead angles. Additionally, starting the first motor directly adjusts the tilt angle of the metal pipe outlet at the end of the rubber corrugated pipe. Using two motors allows for multi-angle adjustment of the metal pipe outlet. Compared to previous technologies, this invention provides flexible adjustment of the pumping steel pipe's output port, enabling flexible adjustment of the concrete delivery direction. The uniform speed of the metal pipe outlet's steering ensures accurate and uniform concrete placement. Furthermore, the entire process can be wirelessly remote-controlled. Adjustment commands are sent from the pump truck's remote control via a wireless signal transmission antenna to the controller, achieving remote control, preventing personnel injury in case of emergencies, and improving safety.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Reference Figures 1-5 A 360-degree rotating concrete pouring placing boom includes a concrete pumping steel pipe 1, a rotating drum 2 rotatably mounted at the lower end of the concrete pumping steel pipe 1, a protective cover 7 sleeved on the outer side of the connection between the concrete pumping steel pipe 1 and the rotating drum 2, and an internal steering assembly 8 inside the protective cover 7; the internal steering assembly 8 includes a mounting plate base 81, the mounting plate base 81 is fixedly mounted on the outer wall of the concrete pumping steel pipe 1 and a second motor 82 is fixedly mounted on the mounting plate base 81, a gear 83 is fixedly mounted on the output end of the second motor 82, a gear ring 84 is fixedly mounted on the outer wall of the rotating drum 2, the gear 83 meshes with the gear ring 84, the protective cover 7 is screwed onto the outer wall of the concrete pumping steel pipe 1, and the rotating drum 2 rotates through the protective cover 7.
[0024] Through the above-mentioned setup, the protective cover 7 provides protection for the junction of the rotating drum 2 and the commercial concrete pumping steel pipe 1, protecting the meshing space of the internal gear 83 and gear ring 84, and preventing dust on site from affecting the meshing of the gear 83 and gear ring 84. It should be noted that the protective cover 7 is made of silicone rubber, which has good support performance and deformation capacity, providing protection for the meshing space of the internal gear 83 and gear ring 84. In addition, when it is necessary to disassemble the protective cover 7, it can be pulled out from the end of the rotating drum 2 through a certain deformation capacity.
[0025] In this method, a controller 9 and a wireless signal transmission antenna 10 are fixedly installed on the outer wall of the protective cover 7.
[0026] With the above-mentioned setup, the controller 9 is used to control the first motor 6 and the second motor 82 to work together to adjust the angle of the metal pipe opening 4. In addition, the wireless signal transmission antenna 10 can realize the function of wireless remote control operation, and remote operation can be performed using the pump truck's remote control.
[0027] In this method, a first annular groove 85 and a second annular groove 86 are provided on the outer wall of the commercial concrete pumping steel pipe 1, and a rubber ring 89 is fitted inside the second annular groove 86.
[0028] By setting up the rubber ring 89 as described above, the connection between the rotating drum 2 and the commercial concrete pumping steel pipe 1 is kept sealed, thus preventing slurry leakage.
[0029] In this method, a snap-fit rotating ring 87 is rotatably provided inside the first annular groove 85, and a number of balls 88 are embedded inside the snap-fit rotating ring 87. The snap-fit rotating ring 87 is screwed onto the inner wall of the rotating cylinder 2.
[0030] With the above-described configuration, the snap-fit swivel ring 87 is screwed onto the rotating drum 2. When the rotating drum 2 needs to be disassembled, the protective cover 7 is first removed and pulled to one side. At this time, the snap-fit swivel ring 87 screwed onto the inside of the rotating drum 2 can be unscrewed, so that the rotating drum 2 is separated from the snap-fit swivel ring 87. Subsequently, the rotating drum 2 can be pulled out from the side end of the commercial concrete pumping steel pipe 1. In addition, the setting of the inner ball bearing 88 of the snap-fit swivel ring 87 reduces its frictional loss with the first ring groove 85.
[0031] In this method, a rubber bellows 3 is fixedly installed at the lower end of the rotating drum 2, and a metal pipe 4 is fixedly installed at the lower end of the rubber bellows 3.
[0032] With the above-mentioned setup, the metal pipe 4 is used to provide a conveying port for commercial concrete. Its structure has high strength, which can ensure its stable guiding and conveying performance. In addition, the rubber corrugated pipe 3 has adaptive deformation performance. When the inclination angle of the metal pipe 4 is adjusted, it maintains a stable connection with the metal pipe 4 through its adaptive deformation capability.
[0033] In this method, support plates 5 are symmetrically arranged on both sides of the rubber corrugated pipe 3, and metal pipe openings 4 are rotatably installed on the inner side of the two support plates 5. A first motor 6 is fixedly installed on the outer wall of the support plate 5. The output end of the first motor 6 passes through to the inner side of the support plate 5 and is fixedly connected to the side wall of the metal pipe opening 4. The support plate 5 is fixedly installed at the lower end of the rotating drum 2.
[0034] With the above-mentioned setup, the first motor 6 can drive the metal pipe 4 to adjust its tilt angle when it starts.
[0035] The working principle of the 360-degree rotating concrete placing boom provided by this utility model is as follows:
[0036] During operation, a test signal is sent to the wireless signal transmission antenna 10 via the remote control on the pump truck. The signal is then transmitted to the controller 9. The controller 9 first starts the second motor 82 and observes whether the drum 2 can rotate 360 degrees around the concrete pumping steel pipe 1 without dead angles. The engagement of gear 83 and gear ring 84 is checked to ensure smooth and uninterrupted rotation. The controller 9 then starts the first motor 6 and observes whether the metal pipe opening 4 can be smoothly adjusted in angle. The rubber corrugated pipe 3 is checked to ensure it adapts to the angle changes of the metal pipe opening 4 and is securely connected. Different angle adjustment commands are repeatedly tested to ensure that the first motor 6 and the second motor 82 work together normally and that the metal pipe opening 4 can be precisely adjusted to the specified angle. When the pump truck starts pumping ready-mixed concrete, the construction personnel, according to the pouring area and requirements, use the remote control on the pump truck... The operator sends adjustment commands via remote control. The wireless signal transmission antenna 10 receives the commands and transmits them to the controller 9. The controller 9 then controls the second motor 82 to operate, causing the rotating drum 2 to rotate the metal pipe 4 360 degrees horizontally, adjusting the horizontal position of the ready-mixed concrete. Simultaneously, the controller 9 controls the first motor 6 to operate as needed, adjusting the inclination angle of the metal pipe 4 to meet the pouring requirements of different heights and angles. During the pouring process, construction personnel continuously observe the pouring situation and adjust the angle of the metal pipe 4 at any time via remote control to ensure the accuracy and uniformity of the ready-mixed concrete distribution. In case of emergencies on site, such as obstacles, construction personnel can quickly send commands via remote control, and the controller 9 will promptly control the motor to adjust the position of the metal pipe 4 to avoid affecting the construction and ensure personnel safety.
