Description

Technical Field

[0001] The invention relates to the technical field of concrete construction, in particular to large-volume concrete pouring equipment. Background Art

[0002] Mass concrete refers to large-volume concrete whose geometric dimensions are not less than one meter. When pouring, this kind of large-volume concrete is prone to shrinkage due to temperature changes caused by material hydration, which makes it easy for large-volume concrete to crack. Therefore, when pouring large-volume concrete, the layered pouring method is often used to effectively dissipate the temperature inside the concrete quickly and reduce the risk of cracks after solidification. Among them, the main method of concrete pouring is to build a formwork for the shaping pouring area. The commonly used pouring method nowadays is to directly pour the material from the discharge pipe at the rear of the concrete tanker into the built formwork for pouring.

[0003] Some existing concrete pump trucks use a process of manually paving and vibrating the concrete layer by layer. This process requires a lot of manpower and mechanical equipment, which increases equipment and labor costs. In addition, the paving of each area is not balanced due to manual operation, which will affect the effect of layered pouring. In addition, the pump pouring pipe and the feed pipe of the concrete pump truck are usually locked with clamp bolts, which makes it difficult to disassemble and connect the pouring pipe, further reducing the construction efficiency. In addition, the existing concrete pouring port is composed of a funnel structure. The funnel is lifted by an external lifting device, and the lower end is aligned with the position to be poured. The concrete enters the inner side of the funnel. When the funnel is blocked by concrete, the lifting device is required to shake the funnel up and down to restore the funnel to be unobstructed. This pouring method encounters some relatively narrow spaces. There is no position to accommodate the lifting device, which makes pouring very troublesome. After pouring the concrete for a period of time, the concrete is easy to solidify, causing the pipe mouth to be blocked. For this reason, in view of the above problems, a large-volume concrete pouring equipment is proposed to solve the above problems. Summary of the invention

[0017] 3. In the present invention, the concrete at the outlet of the pouring pipe impacts the wheel rod and cooperates with the vibration of the vibrating rod to drive the bottom of the pouring pipe to vibrate, so that the multiple vibrations drive the roller to pull the pull plate to reciprocate up and down. This process, combined with the action of spring 2 and spring 1, increases the up and down sliding amplitude and frequency of the dredging cylinder. Through this design, it is ensured that the concrete can be poured continuously and evenly, avoiding construction delays caused by blockage. BRIEF DESCRIPTION OF THE DRAWINGS

The right side of the connecting block 15 is fixedly connected with a hydraulic rod 2 16, and the connecting block 15 supports the hydraulic rod 2 16, and the hydraulic rod 2 16 is tilted and fixed to the middle part of the connecting block 15. The driving end of the hydraulic rod 2 16 is fixedly connected with a clamping ring 17, and the hydraulic rod 2 16 pushes the clamping ring 17 to lock the hook 21, thereby realizing rapid docking of the casting pipe 3 and the feed pipe 2.

[0032] The outside of the snap ring 17 is engaged with the outside of the hook 21, and the snap ring 17 is sleeved on the outside of the hook 21 to fix the arc-shaped bar 14 and the connecting block 15 together. The left ends of the two arc-shaped bars 14 are fixedly connected with the central shaft 19, which is designed to fix the two arc-shaped bars 14 on the one hand and the two arc-shaped bars 20 on the other hand. The outside of the central shaft 19 is rotatably connected to the two arc-shaped bars 20, and the central shaft 19 is a component fixed to the left ends of the two arc-shaped bars 14, and is used to rotatably connect the two arc-shaped bars 20.

[0033] The outside of the arc strip 20 contacts the outside of the feed pipe 2, and the arc strip 20 contacts the feed pipe 2 to achieve quick docking of the pouring pipe 3 and the feed pipe 2. The outside of the arc strip 20 contacts the outside of the pouring pipe 3, and the arc strip 20 wraps the top of the pouring pipe 3. The front end of the arc strip 20 is fixedly connected with a hook 21, and the hook 21 is used to lock the clamp 17. The bottom end of the feed pipe 2 is fixedly connected with a docking ring 23, and the diameter of the docking ring 23 is larger than the top of the feed pipe 2. The top of the pouring pipe 3 is fixedly connected with a docking sleeve 24, and the docking sleeve 24 and the docking ring 23 have the same diameter.

[0034] The middle parts of the two arc-shaped bars 14 are fixedly connected with a plurality of clamping blocks 18 on the outside. The design of the clamping blocks 18 is to increase the connection between the two arc-shaped bars 14 and to increase the clamping force of the arc-shaped bars 14. The outside of the docking ring 23 is engaged with the inner wall of the clamping block 18, and the outside of the docking sleeve 24 is engaged with the inner wall of the clamping block 18. The middle parts of the two arc-shaped bars 14 are fixedly connected with a plurality of central shafts 19 on the outside. The clamping block 18 wraps the docking ring 23 and the docking sleeve 24.

The outside of the docking ring 23 is engaged with the inner wall of the clamping block 22, and the outside of the docking sleeve 24 is engaged with the inner wall of the clamping block 22. The clamping block 22 wraps the docking ring 23 and the docking sleeve 24.

[0035] refer to Figure 6 The bottom of the pouring pipe 3 is fixedly connected to a ball bar cover 25, which is a hemispherical bar cover and fixed in a protruding manner at the mouth of the pouring pipe 3. The middle of the ball bar cover 25 is fixedly connected to a sleeve 26, and the middle of the sleeve 26-ball bar cover 25 is used to support the mouth of the pouring pipe 3, and the top of the pouring pipe 3 is spherical and coated with a lubricating coating on the outside, so that concrete will not hang on the wall. The middle of the bottom of the sleeve 26 is rotatably connected to a wheel rod 27, which is composed of a round rod and a horizontal wheel.

[0036] The end of the wheel rod 27 away from the club cover 25 is fixedly connected to a connecting roller 28. The wheel rod 27 rotates to pull the connecting roller 28 to rotate 360 ​​degrees along the round rod of the wheel rod 27. The top of the connecting roller 28 is rotatably connected to a transmission rod 29. The top of the transmission rod 29 is fixedly connected to a pull plate 30. The wheel rod 27 pulls the transmission rod 29 through the connecting roller 28 to slide up and down along the inner wall of the dredging tube 33. The outer part of the transmission rod 29 is sleeved with a spring 1 31, which is sleeved at the bottom end of the inner wall of the dredging tube 33.

[0037] The top of spring 1 31 is fixedly connected to the bottom of the pull plate 30, and the bottom of spring 1 31 is fixedly connected to the bottom of the inner wall of the dredging cylinder 33. When the pull plate 30 is driven downward by the transmission rod 29, it will be pulled, squeezed and pushed to push the dredging cylinder 33 downward synchronously, and then the dredging cylinder 33 and the pull plate 30 will be driven to reset by its own elastic force, thereby increasing the up and down sliding amplitude and frequency of the dredging cylinder 33. The inner sliding connection of the sleeve 26 is provided with a limit ring 32, and the middle part of the limit ring 32 is fixedly connected with the dredging cylinder 33. The limit ring 32 is fixed to the outside of the dredging cylinder 33 to limit the linear sliding of the dredging cylinder 33. The outer sleeve of the clearing cylinder 33 is provided with a spring 2 34, the bottom end of the spring 2 34 is fixedly connected to the top end of the inner wall of the sleeve 26, and the bottom end of the spring 2 34 is fixedly connected to the top end of the limit ring 32. When the clearing cylinder 33 is indirectly driven downward by the pull plate 30, the spring 2 34 will be pulled. When the pull plate 30 is reset, the elastic force of the spring 2 34 will increase the sliding amplitude and frequency of the clearing cylinder 33 again, so as to achieve high-frequency vibration of the clearing cylinder 33 to clear the outlet of the casting pipe 3.

[0038] Working principle: When in use, the mixed concrete is transported from the feeding pipe 2 to the pouring pipe 3 by the started pouring crane 1, and the position to be poured is irrigated in cooperation with the boom of the pouring crane 1. During the pouring process, the user can adjust the spacing of the vibrating rods 13 around the outlet of the pouring pipe 3 according to the flow rate of the concrete flowing out of the pouring pipe 3, so as to ensure that the concrete at the pouring positions of the pouring pipe 3 at different positions can be fully vibrated, thereby improving the density and quality of the concrete and reducing the generation of internal pores and defects.

[0039] Regarding the spacing adjustment of the motor 12, the limit sleeve 5 can be driven to rise by starting the hydraulic rod 4, so that the support plate 9 is pulled to move horizontally along the inner wall of the slide groove 11 toward the limit sleeve 5 through the rotating rod 7 connected to the limit sleeve 5. When the support plate 9 moves linearly, the support plate 9 fixes the slide groove 11 and presses the slide groove 11 to slide synchronously, so as to adjust the spacing between the vibrating rods 13, so that when the pouring pipe 3 is poured, the vibrating rod 13 can cover the concrete pouring area more comprehensively, ensuring that the concrete at different positions can be fully vibrated, thereby improving the density and quality of the concrete and reducing the generation of internal pores and defects.

[0040] In addition, when the user needs to dock the pouring pipe 3 and the conveying pipe 2, the pouring pipe 3 can be inserted into the conveying pipe 2, and then the arc bar 20 is rotated to align with the arc bar 14, so that the arc bar 20 and the arc bar 14 can wrap the docking ring 23 of the conveying pipe 2 and the docking sleeve 24 of the pouring pipe 3, and then the clamping ring 17 is clamped to the outside of the clamping hook 21, and the hydraulic rod 2 16 is started to lock, so that the pouring process of concrete can be more continuous. When replacing or extending the pouring pipe 3, the docking can be completed quickly, avoiding the interruption of concrete caused by too long connection time, and ensuring the continuity of pouring.

[0041] When the roller 28 is rotated, the spring 1 31 is pulled by the pull plate 30 to make a reciprocating motion up and down. When the pull plate 30 moves up and down, it will first be compressed by the pull plate 30 pulling the spring 1 31, and then stretched by the pulling spring 2 34 of the dredging cylinder 33 and the limit ring 32. In this way, when the roller 28 is rotated and reset, the spring 1 31 will drive the pull plate 30 to slide quickly inside the dredging cylinder 33 through its own elastic force. Due to the rapid sliding of the pull plate 30, the pull plate 30 will rub against the inside of the dredging cylinder 33 and cooperate with the elastic pulling of the spring 2 34, drive the dredging cylinder 33 to retract and contract at the outlet of the casting pipe 3 multiple times, so as to impact the concrete at the outlet of the casting pipe 3, and effectively prevent the outlet of the casting pipe 3 from being blocked.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
