In addition, the pre-reserved structural openings are equipped with steel reinforcement frames, which obstruct the conveying pipes outside the frames, causing some concrete to fall and resulting in resource waste and reduced construction efficiency. Therefore, it is necessary to improve the existing technology. Utility Model Content

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4 The secondary structure concrete pouring rapid construction device shown in the figure includes a concrete pump 1, a conveying mechanism is set on one side of the concrete pump 1, the conveying mechanism is used to convey concrete, the conveying mechanism includes a hopper 11 set on one side of the concrete pump 1, a connecting pipe 12 is set at the lower end of one side of the hopper 11, and one end of the connecting pipe 12 is connected to the conveying pipe 13. Overview of the working principle of concrete delivery pump 1: Concrete delivery pump 1 drives the pumping mechanism through a hydraulic system to realize the continuous suction and pressure delivery of concrete. It is mainly composed of the pumping system, hydraulic and electrical control system and main power system working together to complete the concrete delivery.

[0015] Workflow: Hydraulic drive and piston movement: Pressurized oil from the hydraulic system enters the main cylinder on one side, pushing the piston rod to extend, while simultaneously retracting the piston rod on the other side through the sealed circuit connecting pipe.

[0016] The concrete conveying piston on the retracting side generates a self-priming effect in the conveying cylinder. The concrete in the hopper, propelled by atmospheric pressure and the mixing blades, enters the conveying cylinder through the slide valve inlet.

[0017] The main hydraulic cylinder on the extended side pushes the concrete piston to force the concrete out of the conveying cylinder, and the concrete enters the conveying pipe through the Y-shaped pipe of the slide valve conveying port.

[0018] Automatic reversing and cyclic operation: After a single suction and conveying stroke is completed, the system automatically reverses direction, and the pressurized oil enters the main oil cylinder on the other side to repeat the above suction and conveying process, so as to achieve continuous conveying.

[0019] A hooking mechanism is provided on the outer side of one end of the conveying pipe 13. The hooking mechanism is used to hook one end of the conveying pipe 13. The hooking mechanism includes a limiting ring 14 provided on the outer side of one end of the conveying pipe 13. A movable ring 15 is slidably sleeved on the outer side of the limiting ring 14. A fixed rod 16 is connected to the upper end of the movable ring 15. A pin 17 is provided on the upper end of the fixed rod 16. A pin sleeve 18 is slidably sleeved on the outer side of the pin 17. A hook 19 is provided on the upper end of the pin sleeve 18. A discharge mechanism is provided at one end of the conveying pipe 13. The discharge mechanism is used for concrete discharge. The discharge mechanism includes a discharge head 110 sleeved at one end of the conveying pipe 13. Fixing blocks 111 are symmetrically arranged on one side of the discharge head 110. Bolts 112 are sleeved inside the fixing blocks 111. A vibration mechanism is provided on the lower end face of the hopper 11. The vibration mechanism is used to vibrate and compact concrete. The vibration mechanism includes a motor 2 provided on the lower end face of the hopper 11. One end of the motor 2 is connected to a connecting rod 21, and one end of the connecting rod 21 is connected to a vibrating rod 22. The vibrator 22 is an eccentric vibrator. It utilizes a rotating shaft with an eccentric mass mounted at its center. The centrifugal force generated during high-speed rotation is transmitted to the vibrator 22 housing via bearings, causing the vibrator 22 to vibrate in a circular motion. The concrete vibrator generates intense vibrations through its internal high-frequency vibrator, which are transmitted to the concrete through the rod body. Under the action of vibration, the particles in the concrete rearrange, fill gaps, and expel excess moisture and air bubbles, thereby achieving the densification of the concrete.

[0020] A support mechanism is provided on the outside of the connecting rod 21. The support mechanism is used to provide auxiliary support for the connecting rod 21. The support mechanism includes a support ring 23 sleeved on the outside of the connecting tube 12. The lower end of the support ring 23 is connected to the connecting block 24. The lower end face of the connecting block 24 is in close contact with the support block 25. The internal thread of the support block 25 is connected to the screw 26.

[0021] Please see Figure 1-4 The inner side of the fixing block 111 is in close contact with the conveying pipe 13, and one end of the bolt 112 is threaded to the conveying pipe 13; With this setup, by connecting the discharge head 110 to one end of the conveying pipe 13 and rotating and tightening the screw 112 to connect the threaded conveying pipe 13, it is easy to fix and install the discharge head 110. The tapered structure design of the discharge head 110 makes it easy to insert it into the steel frame with the reserved construction opening for conveying, preventing the conveying pipe 13 from being blocked outside the steel frame, which would cause some concrete to fall and waste resources, and reduce construction efficiency.

[0022] Please see Figure 1-4 The inner sliding sleeve of the movable ring 15 is connected to the conveying pipe 13, and the upper end of the fixed rod 16 is slidably connected to the pin sleeve 18. With this setup, the hook 19 can be attached to the steel frame of the reserved structural opening, reducing the labor required for frequent manual handling of the conveyor pipe 13. The rotatable movable ring 15 and pin sleeve 18 structure design can flexibly adjust the discharge direction of the discharge head 110, improving the flexibility and convenience of the equipment.

[0023] Please see Figure 1-4 The upper end of the screw 26 is threaded to the connecting block 24, and the lower end of the connecting block 24 is internally sleeved with the connecting rod 21. With this setup, by rotating the screw 26 to connect the threaded connecting block 24, the support block 25 is driven to clamp the connecting rod 21 at the bottom of the connecting block 24, which facilitates the support and fixation of the connecting rod 21 and prevents the connecting rod 21 from drooping over a long period of time, which could cause bending and damage to the internal structure of the motor 2 port.

[0024] Please see Figure 1-4 A vibrating rod 22 is installed below the conveying pipe 13; With this setup, by inserting one end of the vibrator 22 into the pre-reserved structural opening and starting the motor 2 to drive the vibrator 22 to vibrate, the concrete inside the pre-reserved structural opening can be compacted by high-frequency vibration, eliminating air bubbles and reducing internal voids.

[0025] The working principle of this embodiment is as follows: This rapid construction device for secondary structure concrete pouring connects the discharge head 110 to one end of the conveying pipe 13 and tightens the screw 112 to the threaded connection of the conveying pipe 13, which facilitates the fixed installation of the discharge head 110. The conical structure design of the discharge head 110 makes it easy to insert it into the steel frame with the reserved construction opening for conveying, preventing the conveying pipe 13 from being blocked outside the steel frame, which would cause some concrete to fall and waste resources, and reduce construction efficiency.

[0026] The design of hook 19 allows it to be attached to the steel frame of the reserved structural opening, reducing the labor required for frequent manual handling of the conveying pipe 13. The rotatable movable ring 15 and pin sleeve 18 structural design allow for flexible adjustment of the discharge direction of the discharge head 110, improving the flexibility and convenience of the equipment.

[0027] By rotating the screw 26 to connect the threaded connecting block 24, the support block 25 is driven to clamp the connecting rod 21 at the bottom of the connecting block 24, which facilitates the support and fixation of the connecting rod 21 and prevents the connecting rod 21 from drooping for a long time, which would cause bending and damage to the internal structure of the motor 2 port. By inserting one end of the vibrating rod 22 into the interior through the reserved structural opening, the motor 2 is started to drive the vibrating rod 22 to vibrate, thereby performing high-frequency vibration to compact the concrete inside the reserved structural opening, eliminating air bubbles and reducing internal voids.
