Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of pipe pile pouring, in particular to a concrete pipe pile pouring device. BACKGROUND
[0002] In the concrete pipe pile pouring operation, the hopper plays a crucial role in storing and conveying concrete to ensure that the concrete can flow uniformly and continuously into the pipe pile.
[0003] Due to the influence of wind, unstable lifting equipment, and the technical level of the operator during lifting, the hopper is prone to shaking, which may cause the hopper to collide with the pipe pile opening, causing damage or deformation of the pipe pile opening. Secondly, the hopper is prone to clogging during use, mainly due to the viscous and granular properties of concrete, which blocks the outlet of the hopper. Clogging not only affects the pouring speed of concrete, but also may cause uneven pouring, thereby affecting the quality and performance of the pipe pile. CONTENT OF THE UTILITY MODEL
[0004] To overcome the shortcomings of the prior art, the present application provides a concrete pipe pile pouring device, which has the advantages of preventing clogging and solving the problems raised in the background art.
[0005] To achieve the above-mentioned purpose, the present application provides the following technical solution: a concrete pipe pile pouring device, comprising a hopper, the bottom end of the hopper is fixedly connected with a drop pipe, the outer surface of the bottom end of the drop pipe is fixedly connected with a hinge ring, the outer surface of the drop pipe is slidably sleeved with a buffer ring, the buffer ring and the hinge ring are fixedly connected with a spring, the inside of the hinge ring is hingedly connected with a plurality of circumferentially arranged first connecting rods, the top end of each first connecting rod is connected with a second connecting rod, and the bottom end of each second connecting rod is hingedly connected with the buffer ring.
[0006] The bottom end of the hopper is fixedly connected with a cross, the center of the cross is slidably inserted with a moving block, the inside of the moving block is rotatably connected with a stirring shaft, the bottom end of the stirring shaft is fixedly connected with a dredging paddle, and the outer surface of the stirring shaft is fixedly connected with a group of stirring paddles.
[0007] The above scheme, through the design of the hinge ring, buffer ring, spring, first connecting rod, and second connecting rod, effectively buffers the swaying of the hopper. When the hopper sways during hoisting due to factors such as wind force, instability of the hoisting equipment, or the operator's skill level, the first connecting rod will collide with the pipe pile opening. At this time, the top of the first connecting rod will flip towards the drop pipe, thereby driving the second connecting rod to push the buffer ring downward and compress the spring. This absorbs and disperses the energy generated by the collision, effectively reducing the impact on the pipe pile opening and avoiding damage or deformation. Through the design of the cross, moving block, mixing shaft, unblocking blade, and mixing blade, intermittent unblocking of the drop pipe and continuous mixing of the concrete inside the hopper are achieved, preventing blockage. At the same time, the mixing blade on the outer surface of the mixing shaft can continuously mix the concrete stored inside the hopper, ensuring the uniformity and fluidity of the concrete, thereby improving the efficiency and quality of pouring.
[0008] Furthermore, a motor is installed at the top of the moving block, and the output end of the motor is fixedly connected to the stirring shaft.
[0009] The above solution, through the installation of a motor, can provide power for the rotation of the stirring shaft.
[0010] Furthermore, two connecting plates are fixedly connected to the outer surface of the motor, and two first hydraulic rods are installed inside the cross, with the output ends of the two first hydraulic rods fixedly connected to the connecting plates close to them.
[0011] The above scheme, through the setting of the first hydraulic rod, can drive the moving block to make up-and-down reciprocating motion.
[0012] Furthermore, a set of lifting rings is fixedly connected to the top of the outer surface of the hopper.
[0013] The above solution, with its lifting rings, makes it easier for users to perform hoisting operations.
[0014] Furthermore, the hopper and discharge pipe are made of high-strength wear-resistant alloy steel.
[0015] Through the above scheme, high-strength wear-resistant alloy steel has excellent mechanical and wear-resistant properties, can withstand the high pressure and impact during concrete pouring, and has good corrosion resistance, can resist the erosion of chemicals in concrete, and extend the service life of the device.
[0016] Furthermore, a hopper wall vibrator is installed on the outer surface of the hopper.
[0017] The above solution, through the installation of the silo wall vibrator, can cause the concrete inside the hopper and discharge pipe to vibrate, reducing internal air bubbles and further preventing blockage of the discharge pipe.
[0018] Furthermore, a plurality of second hydraulic rods arranged in a circular pattern are fixedly connected to the outer surface of the hopper, and a support plate is fixedly connected to the output end of each second hydraulic rod.
[0019] The above scheme, through the installation of the second hydraulic rod and the support plate, can achieve the purpose of supporting the whole structure.
[0020] Furthermore, a control host is installed on the outer surface of the hopper, and the motor, hopper wall vibrator, first hydraulic rod and second hydraulic rod are all electrically connected to the control host.
[0021] The above scheme, through the configuration of the control host, enables the control of electrical components.
[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0023] This concrete pipe pile pouring device effectively buffers the swaying of the hopper through the design of a hinged ring, buffer ring, spring, first connecting rod, and second connecting rod. When the hopper sways during hoisting due to factors such as wind, instability of the hoisting equipment, or the operator's skill level, the first connecting rod will collide with the pipe pile opening. At this time, the top of the first connecting rod will flip towards the drop pipe, thereby driving the second connecting rod to push the buffer ring downward and compress the spring. This absorbs and disperses the energy generated by the collision, effectively reducing the impact on the pipe pile opening and avoiding damage or deformation. Through the design of the cross, moving block, mixing shaft, unblocking blade, and mixing blade, intermittent unblocking of the drop pipe and continuous mixing of the concrete inside the hopper are achieved, preventing blockage. At the same time, the mixing blade on the outer surface of the mixing shaft can continuously mix the concrete stored inside the hopper, ensuring the uniformity and fluidity of the concrete, thereby improving the efficiency and quality of pouring.

The top end of each first connecting rod 6 is connected to a second connecting rod 7, and the bottom end of each second connecting rod 7 is hinged to the buffer ring 4. With the above arrangement, when the hopper 1 swings, when the first connecting rod 6 collides with the pipe pile opening, the top end of the first connecting rod 6 flips towards the material drop pipe 2, thereby driving the second connecting rod 7 to push the buffer ring 4 downward and compress the spring 5, which can achieve the purpose of energy absorption and buffering, thereby reducing the collision with the pipe pile opening.
[0032] Please see Figure 1 , Figure 2 and Figure 3 A set of lifting rings 16 are fixedly connected to the top of the outer surface of the hopper 1. The lifting rings 16 facilitate hoisting by the user. The hopper 1 and the discharge pipe 2 are made of high-strength wear-resistant alloy steel. High-strength wear-resistant alloy steel has excellent mechanical properties and wear resistance, and can withstand the high pressure and impact during the concrete pouring process. At the same time, it has good corrosion resistance and can resist the erosion of chemicals in concrete, thus extending the service life of the device. A bin wall vibrator 17 is installed on the outer surface of the hopper 1. The bin wall vibrator 17 can make the concrete inside the hopper 1 and the discharge pipe 2 vibrate, reduce the air bubbles in the internal cavity, and further prevent the discharge pipe 2 from clogging.
[0033] Please see Figure 1 , Figure 2 and Figure 4A cross 8 is fixedly connected to the inner wall of the bottom end of the hopper 1. A moving block 9 is slidably inserted into the center of the cross 8. A stirring shaft 10 is rotatably connected inside the moving block 9. A clearing blade 11 is fixedly connected to the bottom end of the stirring shaft 10. A set of stirring blades 12 is fixedly connected to the outer surface of the stirring shaft 10. With the above configuration, the purpose of clearing the discharge pipe 2 can be achieved, and the concrete stored inside the hopper 1 can be continuously stirred. A motor 13 is installed at the top of the moving block 9. The output end of the motor 13 is fixedly connected to the stirring shaft 10. With the motor 13, power can be provided for the rotation of the stirring shaft 10.
[0034] Please see Figure 1 , Figure 2 and Figure 3 Two connecting plates 14 are fixedly connected to the outer surface of the motor 13. Two first hydraulic rods 15 are installed inside the cross 8. The output ends of the two first hydraulic rods 15 are fixedly connected to the connecting plates 14 close to them. Through the setting of the first hydraulic rods 15, the moving block 9 can be driven to move up and down reciprocatingly. Multiple second hydraulic rods 18 arranged in a circle are fixedly connected to the outer surface of the hopper 1. The output end of each second hydraulic rod 18 is fixedly connected to a support plate. Through the setting of the second hydraulic rods 18 and the support plate, the purpose of supporting the whole can be achieved. A control host 19 is installed on the outer surface of the hopper 1. The motor 13, the bin wall vibrator 17, the first hydraulic rods 15 and the second hydraulic rods 18 are all electrically connected to the control host 19. Through the setting of the control host 19, the purpose of controlling the electrical components can be achieved.
[0035] This embodiment of a concrete pipe pile pouring device, through the design of hinge ring 3, buffer ring 4, spring 5, first connecting rod 6 and second connecting rod 7, effectively buffers the swaying of hopper 1. When hopper 1 sways during hoisting due to factors such as wind force, instability of hoisting equipment, or operator skill level, the first connecting rod 6 will collide with the pipe pile opening. At this time, the top of the first connecting rod 6 will flip towards the drop pipe 2, thereby driving the second connecting rod 7 to push the buffer ring 4 downward and compress the spring 5, which can absorb and disperse the energy generated by the collision, effectively reducing the impact on the pipe pile opening and avoiding damage or deformation of the pipe pile opening. Through the design of cross 8, moving block 9, mixing shaft 10, unblocking blade 11 and mixing blade 12, intermittent unblocking of drop pipe 2 and continuous mixing of concrete inside hopper 1 are achieved to prevent blockage. At the same time, the mixing blade 12 on the outer surface of mixing shaft 10 can continuously mix the concrete stored inside hopper 1, ensuring the uniformity and fluidity of concrete, thereby improving the efficiency and quality of pouring.
[0036] The working principle of the above embodiment is as follows: the hoisting ring 16 at the top of the hopper 1 is connected to the hoisting equipment to achieve overall hoisting and positioning. During the hoisting process, due to factors such as wind force, instability of the hoisting equipment, or the skill level of the operator, the hopper 1 may shake. When the hopper 1 shakes and collides with the pipe pile opening, the top of the first connecting rod 6 will flip towards the discharge pipe 2. This action will drive the second connecting rod 7 to move downward, thereby pushing the buffer ring 4 to slide along the outer surface of the discharge pipe 2 and compress the spring 5. The compression process of the spring 5 can absorb and disperse the energy generated by the collision, effectively reducing the impact on the pipe pile opening, thereby avoiding damage or deformation of the pipe pile opening. After the concrete is poured into the hopper 1... When the motor 13 starts, the mixing blades 12 on the outer surface of the mixing shaft 10 continuously mix the concrete stored inside the hopper 1 to ensure the uniformity and fluidity of the concrete. During the mixing process, the moving block 9 is driven to move up and down by the first hydraulic rod 15, which can drive the unblocking blades 11 to intermittently insert into the inside of the discharge pipe 2 to unblock it and prevent the discharge pipe 2 from getting blocked. The hopper wall vibrator 17 on the outer surface of the hopper 1 can further prevent the discharge pipe 2 from getting blocked. The vibration reduces the air bubbles in the concrete cavity and improves the density and strength of the concrete. The multiple circumferentially arranged second hydraulic rods 18 and support plates provide stable support force to ensure the stability and safety of the device during the pouring process.
