Description

Technical Field

[0001] This utility model relates to the field of concrete conveying, and in particular to a concrete pouring device. Background Technology

[0002] In the field of concrete construction, traditional pouring devices usually adopt a fixed or simple rotary discharge structure. For example, Chinese patent application number CN202322356938.4 discloses a new type of concrete pouring device, which belongs to the field of construction device technology. One end of the pouring funnel is equipped with a steel pipe frame, and the other end of the pouring funnel is equipped with a discharge pipe. One end of the discharge pipe is fixedly installed with a conveying pipe, and the other end of the conveying pipe is fixedly installed with a discharge head. The surface of the discharge head is fixedly connected with a lower hanging ring and a handle. The center of the discharge head is provided with a discharge hole. The surface of the discharge pipe is fixedly sleeved with a positioning sleeve, the surface of the positioning sleeve is rotatably connected with a rotating sleeve, and the surface of the rotating sleeve is fixedly connected with an upper hanging ring.

[0003] Although such devices can achieve the function of foundation pouring, they still have significant defects in actual construction: 1. Insufficient adjustment flexibility; 2. Poor angle stability; 3. The pipe body is easy to bend, which leads to a high risk of pipe blockage.

[0004] Therefore, there is an urgent need for a concrete pouring device that can solve the above-mentioned technical problems. Utility Model Content

[0005] To address the problems of insufficient adjustment flexibility, poor angle stability, and high risk of pipe blockage due to easy bending of the pipe in existing technologies, this utility model proposes a concrete pouring device, the technical solution of which is as follows:

[0006] A concrete pouring device includes a pouring funnel, a discharge pipe coaxially rotatably connected to the discharge end of the funnel, a circumferential locking mechanism between the discharge pipe and the pouring funnel to lock the discharge pipe so that it cannot rotate, and a bending angle adjustment mechanism is provided on the body of the discharge pipe.

[0007] The bending angle adjustment mechanism includes several adjusting rings spaced apart along the axis of the discharge pipe. The adjusting rings are fixedly sleeved on the outer peripheral wall of the discharge pipe. A connecting member is provided between two adjacent adjusting rings. The connecting member pivotally connects two adjacent adjusting rings, so that the two adjacent adjusting rings and the discharge pipe section they are connected to can rotate relative to each other around a pivot axis perpendicular to the axis of the discharge pipe. The adjusting rings are also provided with a locking mechanism to fix the bending angle posture of the discharge pipe.

[0008] The locking mechanism includes fixing points respectively set on the adjusting rings at both ends of the discharge pipe, and adjusting belts fixed at both ends to these two fixing points respectively.

[0009] Furthermore, one of the adjusting rings is located at the rotating connection of the discharge pipe. The circumferential locking mechanism includes a fixed plate circumferentially arranged on the adjusting ring. A fixed plate extends downward from the wall of the casting funnel to above the fixed plate. A portion of the fixed plate is horizontally bent to form a fixed section parallel to the fixed plate. Several fixed through holes are provided on the fixed plate and the fixed section. Bolts are used to pass through the fixed through holes on the fixed plate and the fixed section to lock the discharge pipe from circumferential rotation.

[0010] Furthermore, the discharge pipe body is made of flexible material, the adjusting ring is a section of rigid pipe and is fixed to the outer wall of the discharge pipe, and there is a gap between adjacent adjusting rings.

[0011] Furthermore, threaded holes are provided on both sides of the adjusting ring, and the connecting member is a metal plate with movable holes at both ends. Bolts pass through the movable holes and are screwed into the threaded holes, so that the metal plate is rotatably connected to the adjacent adjusting ring.

[0012] Furthermore, the adjusting rings are provided with clearance openings at both ends to prevent interference between two adjacent adjusting rings during rotation.

[0013] Furthermore, the fixing point includes two fixing ears that are parallel to each other and perpendicular to the axis of the adjusting ring, and a fixing shaft for connecting the adjusting belt is provided between the fixing ears.

[0014] Furthermore, the adjusting belt has several fixing holes along its length. The adjusting belt is wrapped around the fixing shaft and then folded back, causing the adjusting belt to overlap. The two layers of the overlapping area of ​​the adjusting belt are aligned with the corresponding fixing holes. Fixing bolts are then passed through the two aligned fixing holes simultaneously to secure the belt, thereby locking the length of the adjusting belt and the bending angle of the discharge pipe.

[0015] Furthermore, a metal ring is provided around the fixing hole to prevent deformation of the fixing hole.

[0016] Furthermore, a one-way dredging interface is provided on the adjusting ring located on the side of the discharge pipe away from the pouring funnel, which connects to the inside of the discharge pipe. A high-pressure water gun can be inserted into the one-way dredging interface to flush the discharge pipe and prevent blockage.

[0017] The beneficial effects of this utility model are as follows: Through the coordinated design of the segmented adjusting ring and the pivoting connector, continuous flexible bending of the discharge pipe in three-dimensional space is achieved, which significantly improves the flexibility and adaptability of casting complex structures. Moreover, the adjusting ring provides rigid support to the outer wall of the discharge pipe, preventing blockage caused by excessive bending of the discharge pipe. At the same time, the circumferential locking mechanism formed by the fixing plate at the casting funnel and the fixing plate of the adjusting ring completely eliminates the rotational displacement at the root of the discharge pipe through bolt tightening. Combined with the mechanical locking mechanism of the adjusting belt and the fixing point, a double stable structure is formed, which effectively resists the impact of concrete flow and ensures that the bending angle of the pipe body remains absolutely rigidly fixed during construction, greatly improving the casting accuracy. In addition, the high-pressure water gun unidirectional unblocking interface integrated at the end, combined with the flexible pipe design, actively reduces the risk of blockage and achieves rapid online unblocking, comprehensively solving the systemic defects of traditional devices such as adjustment limitations, positioning instability, and frequent blockage.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] A concrete pouring device includes a pouring funnel 1, which is erected at the location where pouring is required by a support. Its discharge end is coaxially rotatably connected to a discharge pipe 2. A circumferential locking mechanism is provided between the discharge pipe 2 and the pouring funnel 1 to lock the discharge pipe 2 so that it cannot rotate. The body of the discharge pipe 2 is provided with a bending angle adjustment mechanism.

[0024] The bending angle adjustment mechanism includes several adjusting rings 3 spaced apart along the axis of the discharge pipe 2. The adjusting rings 3 are fixedly sleeved on the outer peripheral wall of the discharge pipe 2. A connecting piece 4 is provided between two adjacent adjusting rings 3. The connecting piece 4 pivotally connects two adjacent adjusting rings 3, so that the two adjacent adjusting rings 3 and the discharge pipe 2 segments they are connected to can rotate relative to each other around a pivot axis perpendicular to the axis of the discharge pipe 2. Through the spaced adjusting rings 3 and the pivot connecting piece 4, the adjacent discharge pipe 2 segments can rotate relative to each other around the vertical axis, realizing smooth bending adjustment. The adjusting rings 3 are also provided with a locking mechanism to fix the bending angle posture of the discharge pipe 2, ensuring stability during the casting process and preventing pipe deformation or displacement.

[0025] The locking mechanism includes fixing points set on the adjusting rings 3 at both ends of the discharge pipe 2, and adjusting belts 7 fixed at both ends of the two fixing points respectively. The adjusting belts 7 are used to connect the fixing points at both ends of the discharge pipe 2. The overall bending angle and posture are fixed by adjusting and locking the length of the adjusting belts 7, which simplifies the operation and enhances the structural rigidity, preventing the discharge pipe 2 from rebounding or loosening during pouring.

[0026] like Figure 1 , Figure 2 , Figure 3 As shown, preferably, one of the adjusting rings 3 is set at the rotating connection of the discharge pipe. The circumferential locking mechanism includes a fixed plate 8 circumferentially arranged on the adjusting ring 3. A fixed plate 9 extends downward from the wall of the casting funnel 1 to above the fixed plate 8. A part of the fixed plate 9 is bent horizontally to form a fixed section 10 parallel to the fixed plate 8. Several fixed through holes are opened on the fixed plate 8 and the fixed section 10. By using bolts to pass through the fixed through holes opened on the fixed plate 8 and the fixed section 10, the discharge pipe 2 can be locked so that it cannot rotate circumferentially.

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, preferably, the body of the discharge pipe 2 is made of flexible material, and the adjusting ring 3 is a section of rigid pipe fixed to the outer wall of the discharge pipe 2. There is a movable gap between adjacent adjusting rings 3. The flexible discharge pipe 2 body combined with the rigid adjusting ring 3 allows bending deformation to adapt to complex angles, while the rigid ring provides support strength. The movable gap design avoids friction or jamming between adjacent adjusting rings 3 during rotation, improving the smoothness of adjustment.

[0028] like Figure 1 , Figure 2 , Figure 3As shown, preferably, the adjusting ring 3 has threaded holes on both sides, and these threaded holes are blind holes. The connecting member 4 is a metal plate with movable holes at both ends. Bolts pass through the movable holes and are screwed into the threaded holes, allowing the metal plate to be rotatably connected to the adjacent adjusting ring 3. Using a metal plate with movable holes and bolts screwed into the threaded holes of the adjusting ring 3 achieves a simple and reliable pivot connection, facilitating assembly and maintenance while ensuring flexible rotation and durability. Preferably, the connecting member 4 can also be rotatably connected to the adjacent adjusting ring 3 via rivets.

[0029] like Figure 1 , Figure 2 , Figure 3 As shown, preferably, the adjusting ring 3 has clearance openings 12 at both ends to prevent interference between two adjacent adjusting rings 3 during rotation. The clearance openings 12 at both ends of the adjusting ring 3 provide space for the relative rotation of adjacent adjusting rings 3, preventing mechanical interference when the rotation angle is too large, and ensuring smooth and unobstructed bending adjustment.

[0030] like Figure 1 , Figure 2 , Figure 3 As shown, preferably, the fixing point includes two fixing ears 5 that are parallel to each other and perpendicular to the axis of the adjusting ring 3, and a fixing shaft 6 for connecting the adjusting belt 7 is provided between the fixing ears 5. The fixing ears 5 and the fixing shaft 6 form a fixing point, providing a stable connection base for the adjusting belt 7, enhancing the uniformity of force distribution, and preventing the adjusting belt 7 from slipping or being damaged during the locking process.

[0031] like Figure 1 As shown, preferably, the adjusting belt 7 has several fixing holes along its length. The adjusting belt 7 is wrapped around the fixing shaft 6 and then folded back, causing the adjusting belt 7 to overlap itself. The two layers of the overlapping area of ​​the adjusting belt 7 are aligned with the corresponding fixing holes. Fixing bolts are then passed through the two aligned fixing holes simultaneously to secure the belt, thereby locking the length of the adjusting belt 7 and the bending angle of the discharge pipe 2. The adjusting belt 7 achieves self-overlapping locking through the fixing holes and fixing bolts, allowing users to quickly adjust and fix its length, thereby precisely controlling the bending angle of the discharge pipe 2. The operation is simple and the locking is reliable.

[0032] like Figure 1 As shown, preferably, a metal ring 13 is provided around the fixing hole to prevent deformation of the fixing hole. The metal ring 13 around the fixing hole enhances the strength of the hole wall, prevents the fixing hole from deforming or tearing during repeated use, extends the life of the adjustment belt 7, and ensures the long-term effectiveness of the locking mechanism.

[0033] like Figure 2 , Figure 3As shown, preferably, the adjusting ring 3 located on the side of the discharge pipe 2 away from the pouring funnel 1 is provided with a one-way unblocking interface 11 that connects to the inside of the discharge pipe 2. A high-pressure water gun can be inserted into the one-way unblocking interface 11 to flush the discharge pipe 2 and prevent blockage. The one-way unblocking interface 11 allows the high-pressure water gun to be inserted to flush the inside of the discharge pipe 2, preventing concrete residue blockage, simplifying maintenance, and improving equipment durability and pouring continuity. The unblocking interface 11 is a quick-connect coupling, a component that is widely used in the prior art and will not be described in detail here.

[0034] It should also be noted that the rotational connection between the discharge pipe 2 and the casting funnel 1 is achieved through a rotary flange or a standard rotary joint in the prior art, which is existing technology and will not be elaborated here.

[0035] The method of using this concrete pouring device is as follows: First, connect the discharge end of the discharge pipe 2 to the pouring funnel 1 coaxially, and lock the discharge pipe 2 with a circumferential locking mechanism to prevent it from rotating circumferentially; then, adjust the bending angle of the discharge pipe 2 with a bending angle adjustment mechanism, manually bend the pipe section of the discharge pipe 2 so that the adjacent adjusting rings 3 rotate relative to each other around the pivot axis to the required angle, and use the connecting piece 4 to ensure flexible rotation; then, use the adjusting belt 7 to connect the fixed points at both ends of the discharge pipe 2, wrap the adjusting belt 7 around the fixed shaft 6 and then fold it back and overlap it, align it with the fixed hole and tighten it with the fixing bolt to lock the length of the adjusting belt 7, thereby fixing the bending angle posture of the discharge pipe 2; during the pouring process, if it is necessary to change the angle, the adjusting belt 7 can be loosened, readjusted and then locked again; in addition, after pouring, the inside of the discharge pipe 2 can be rinsed with a high-pressure water gun inserted through the one-way unblocking interface 11 to prevent concrete blockage, ensure the cleanliness of the equipment and smooth use next time. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
