Description
Technical Field
[0001] The present application relates to the technical field of civil engineering for water conveyance pipelines, and particularly to a concrete pouring device. Background Art
[0002] During the construction of a hydropower station, it is necessary to build some large water conveyance pipelines around the hydropower station to connect to the downstream pipelines for drainage. In order to improve the service life of the water conveyance pipelines, generally, after the shape of the water conveyance pipelines is excavated, concrete is poured to improve the strength of the water conveyance pipelines.
[0003] During the process of pouring concrete into the water conveyance pipelines, a concrete delivery pump truck is generally used to transport the concrete to the position where it needs to be poured. In order to prevent the concrete from segregation during the process of falling from the pipeline of the concrete delivery pump truck, the construction requirements stipulate that the slump of the concrete should not exceed 2m. However, there is a height difference of more than 2m between the upstream and middle reaches of the water conveyance pipelines, and the concrete delivery pump truck is initially located upstream and is not easy to move. Therefore, multiple chutes are added to the delivery pipeline of the concrete delivery pump truck to meet the construction requirements.
[0004] In the related art, a connection sling is installed at the top of the chute, and a fixed ring with a C-shaped opening is welded on the outer wall below the chute. The opening direction of the fixed ring is along the horizontal direction away from the outer wall of the chute. When assembling multiple chutes, the fixed ring on the upper chute hooks the connection sling on the lower chute.
[0005] In view of the above-mentioned related art, during the pouring process, the pipeline on the concrete delivery pump truck needs to drive multiple chutes to move for pouring at different positions. When the chute moves along with the concrete construction pipeline, it will swing under the action of inertia. Also, due to the opening on the fixed ring, the connection between adjacent two chutes is relatively unstable. As the number of chutes increases, the swing amplitude of the chutes becomes larger, which may cause the connection sling to easily fall off from the fixed ring, resulting in safety accidents. Utility Model Content
[0006] In order to improve the connection stability between adjacent two chutes, the present application provides a concrete pouring device.
[0007] A concrete pouring device provided by the present application adopts the following technical solutions:
[0008] A concrete pouring device includes a chute and a hook. A sling is fixedly installed at the top of the chute. The hook is arranged on the outer wall of the chute for the sling to hang. A hanging opening for the sling to enter is formed at the top of the hook. A limiting rod is arranged at the hanging opening to prevent the sling from slipping out of the hanging opening. One side of the limiting rod is hinged to the hook, and the other side is provided with a connecting piece detachably installed on the hook.
[0009] In order to make the limit rod more stable after being fixed to the hook so that the lifting ring is not easily detached from the hook, the connecting member is a connecting bolt and a locknut, and the connecting bolt sequentially passes through the limit rod and the hook and is threadedly connected to the locknut.
[0010] In order to improve the convenience of fixing and disassembling the limit rod, the connecting member is a pin shaft and a retaining pin. The pin shaft sequentially passes through the limit rod and the hook, and the retaining pin is installed on the pin shaft to limit the pin shaft on the limit rod and the hook.
[0011] In order to be able to adjust the depth of insertion of the upper hopper into the lower hopper between two adjacent hoppers so that the water slurry is not easily splashed out during the concrete conveying process, a regulating plate is fixedly installed on the outer wall of the hopper. The extending direction of the regulating plate is the same as the extending direction of the hopper, and the hook is detachably installed on the regulating plate. The distance between the hook and the lifting ring of the same hopper can be adjusted along the extending direction of the regulating plate.
[0012] In order to facilitate the adjustment of the position of the hook on the regulating plate, a fixing bolt is provided on the hook, and an adjusting hole for installing the fixing bolt is formed on the regulating plate. A plurality of the adjusting holes are provided, and the plurality of adjusting holes are arranged at intervals along the extending direction of the regulating plate.
[0013] In order to make it more convenient for the lower hopper to be hung on the hook of the upper hopper, an extending hanging ring for increasing the connection length between two adjacent hoppers is provided on the lifting ring.
[0014] In order to make it more convenient to install the extending hanging ring on the lifting ring, a connection opening for the lifting ring to enter is formed on the extending hanging ring, and an adjusting sleeve capable of blocking the connection opening is provided on one side of the connection opening. The adjusting sleeve is threadedly installed on the extending hanging ring.
[0015] In order to prevent the hopper from being easily dented and deformed greatly when the concrete block attached to the inner wall of the hopper is vibrated off by hammering the hopper, a reinforcing ring for hammering the hopper to vibrate the concrete on the inner wall of the hopper is sleeved on the hopper.
[0016] In summary, the present application includes at least one of the following beneficial technical effects:
[0017] 1. After the sling is hung on the hook through the hanging opening, rotate the limit rod to block the hanging opening, and then fix the limit rod through the connecting piece to limit the sling on the hook, making it difficult for the sling to disengage from the hook, thereby improving the stability after the connection between two adjacent chutes. In addition, when disassembling two adjacent chutes, simply remove the connecting piece, which is relatively convenient;
[0018] 2. Since the water slurry in the concrete will splash when the concrete flows in the chute, if the upper chute is inserted into the lower chute with a shallow depth between two adjacent chutes, the water slurry is likely to splash out from the gap between the two adjacent chutes. Therefore, the depth of the upper chute inserted into the lower chute can be adjusted by adjusting the position of the hook on the adjusting plate, so that the water slurry is not easily splashed out;
[0019] 3. Since the sling is fixedly installed on the chute, the fit at the connection of the two chutes is relatively rigid after connection. The provision of the extended hanging ring enables the connection of the two chutes to have a shaking gap, making the connection between the two chutes a flexible fit, thereby being able to relieve some stresses at the connection of the two chutes and making it not easy for the sling and hook of the chute to break;
[0020] After the use of the chute, a hammer is used to strike its outer wall to vibrate and drop the concrete adhering to the inner wall of the chute, and the strengthening ring increases the strength at the striking part, making it not easy for the chute to produce large deformation and affect the use.

Detailed implementation manners
[0028] The following further elaborates on this application in conjunction with Figure 1-6 accompanying drawings.
[0029] An embodiment of this application discloses a concrete pouring device. Embodiment 1: Referring to Figure 1 and Figure 2 , the concrete pouring device includes a chute 1 and a hook 2. A lifting ring 11 is welded to the top of the chute 1, and the hook 2 is arranged on the outer wall of the chute 1. During the process of pouring concrete, multiple chutes 1 are connected in series along the vertical direction, and adjacent chutes 1 are connected by the hook 2 and the lifting ring 11. The hook 2 is provided with a hanging opening 21 for the lifting ring 11 on another chute 1 to enter for hooking the chute 1. A limiting rod 22 is rotatably installed at the hanging opening 21 to prevent the lifting ring 11 from detaching from the hook 2 of another chute 1. A connecting piece 3 is arranged on the side of the limiting rod 22 away from the rotating end, and the connecting piece 3 is detachably installed on the hook 2, so that the limiting rod 22 blocks or opens the hanging opening 21.
[0030] The chute 1 is a rotating body and a conical sleeve. Such a design enables the smaller-diameter end of the upper chute 1 to smoothly insert into the larger-diameter end of the lower chute 1 between adjacent chutes 1. Thus, the concrete can smoothly enter the lower chute 1 from the upper chute 1 and is not likely to splash out from the gap where the two chutes 1 are spliced.
[0031] Referring to Figure 1 and Figure 2 , a reinforcing ring 12 is sleeved and welded on the outer wall of the middle part of the chute 1. When knocking on the outer wall of the chute 1 with a hammer to vibrate the concrete adhering to the inner wall of the chute 1, the reinforcing ring 12 can be knocked with a hammer, so that the chute 1 is not likely to undergo serious deformation due to long-term knocking.
[0032] If the side with the larger outer diameter of the string tube 1 is set as the top of the string tube 1, then the side with the smaller outer diameter of the string tube 1 is the bottom of the string tube 1. The lifting ring 11 is located at the top of the string tube 1 and is welded to the inner wall of the string tube 1, so that the contact area between the lifting ring 11 and the string tube 1 is relatively large and more stable after welding. One end of the lifting ring 11 protrudes from the side with the larger outer diameter of the string tube 1 to facilitate connection with the hook 2 on the adjacent string tube 1.
[0033] Refer to Figure 1 With Figure 3 , an extension hanging ring 13 (a standard quick-connect ring) is connected to the lifting ring 11, and the extension hanging ring 13 is hooked and suspended on the lifting ring 11. One or more extension hanging rings 13 can be provided. When multiple extension hanging rings 13 are provided, the multiple extension hanging rings 13 are connected in series to form a chain. On the one hand, under the action of the extension hanging ring 13, the length between two adjacent string tubes 1 can be increased, and the number of string tubes 1 used at the construction site can be reduced; on the other hand, since the string tube 1 is a conical barrel, it is more convenient to connect two adjacent string tubes 1 by hanging the extension hanging ring 13 on the hook 2.
[0034] The extension hook 2 includes two straight rod portions and two arc rod portions. The two straight rod portions are arranged at intervals. The two arc rod portions are respectively at the two ends of the two straight rod portions, and the two straight rod portions are respectively at the two ends of the same arc rod portion, that is, each arc rod portion and the two straight rod portions together form a U-shaped rod, and the two straight rods and the two U-shaped rods are integrally formed.
[0035] Refer to Figure 1 With Figure 3 , a connection opening 131 for the lifting ring 11 to enter the inside of the extension hook 2 is provided at the middle position of one of the straight rod portions. The straight rod portion provided with the connection opening 131 is partitioned into two sections by the connection opening 131, and external threads are provided on the outer walls of the straight rod portions divided by the connection opening 131 into two sections. An adjusting sleeve 14 is sleeved and threadedly installed on one of the straight rod portions divided by the connection opening 131 into two sections. Rotating the adjusting sleeve 14 can make the adjusting sleeve 14 block the connection opening 131, so that the lifting ring 11 is not easily disconnected from the extension hook 2. Similarly, if it is necessary to remove the extension hook 2 from the lifting ring 11, just turn the adjusting sleeve 14 to open the connection opening 131.
[0036] Refer to Figure 1 With Figure 2The hook 2 is located at the middle and lower position of the outer wall of the string tube 1, and the hanging opening 21 is located on the side of the hook 2 close to the top of the string tube 1. A rotating pin 23 is welded on the side wall of the hanging opening 21 close to the outer wall of the string tube 1, and the side of the limit rod 22 close to the outer wall of the string tube 1 is sleeved on the rotating pin 23 and rotates with the rotating pin 23 as the rotation axis. The end of the rotating pin 23 away from the hook 2 along its own extension direction is integrally formed with an outer convex edge for limiting the limit rod 22, so that the limit rod 22 is not easy to detach from the rotating pin 23. When installing, the limit rod 22 can be sleeved on the rotating pin 23 first, and then the rotating pin 23 can be welded to the hook 2.
[0037] In this embodiment, the connecting member 3 is preferably a connecting bolt 31 and a locking nut 32. A through hole 221 is provided on the side of the limiting rod 22 away from the rotating pin 23, and a mounting hole 222 connected to the through hole 221 is provided on the hook 2. The threaded end of the connecting bolt 31 passes through the through hole 221 and the mounting hole 222 in sequence and is threadedly connected to the locking nut 32, thereby fixing the limiting rod 22 on the hook 2.
[0038] Reference Figure 1 and Figure 4 An adjustment plate 15 is welded on the outer wall of the string tube 1, and the hook 2 is installed on the adjustment plate 15. The position of the hook 2 on the adjustment plate 15 can be adjusted, so that the insertion depth between two adjacent string tubes 1 can be adjusted.
[0039] The extension direction of the adjustment plate 15 is consistent with the extension direction of the string tube 1, and because the string tube 1 is a tapered sleeve, the adjustment plate 15 is tilted on the string tube 1. The hook 2 is provided with a fixing hole 24, and a fixing bolt 25 is inserted into the fixing hole 24. The adjustment plate 15 is provided with an adjustment hole 151 for the threaded end of the fixing bolt 25 to pass through. After the fixing bolt 25 passes through the adjustment hole 151, the hook 2 is fixed to the adjustment plate 15 by a nut. There are multiple adjustment holes 151, and the multiple adjustment holes 151 are arranged at intervals along the extension direction of the adjustment plate 15. When the position of the hook 2 on the adjustment plate 15 needs to be adjusted, the hook 2 only needs to be installed at the corresponding adjustment hole 151 position through the cooperation of the fixing bolt 25 and the nut.
[0040] The implementation principle of a concrete pouring device in an embodiment of the present application is as follows: when a string tube 1 is needed to pour concrete, in order to facilitate the connection between two adjacent string tubes 1, the bottom of the upper string tube 1 can be inserted into the top of the lower string tube 1, and then the extended hanging ring 13 is hung on the hook 2 through the hanging opening 21, and then the limit rod 22 is rotated so that the limit rod 22 blocks the hanging opening 21; finally, the limit rod 22 is fixed to the hook 2 by the connecting bolt 31 and the anti-loosening nut 32.
[0041] If you want to adjust the depth of the upper chute 1 inserted into the lower chute 1, you can adjust the position of the hook 2 on the adjusting plate 15, and then adjust it according to the actual situation at the construction site, so that the water slurry in the concrete is not easily splashed out between two adjacent chutes 1.
[0042] Embodiment 2; Refer to Figure 5 And Figure 6 , the difference between this embodiment and Embodiment 1 is that the connecting member 3 is a pin shaft 33 and a retaining pin 34. A pin hole 331 is formed in the outer wall on one side of the pin shaft 33. One end of the pin shaft 33 close to the pin hole 331 sequentially passes through the through hole 221 and the mounting hole 222, and then the retaining pin 34 is inserted into the pin hole 331 to limit the pin shaft 33 on the hook 2, so that the pin shaft 33 is not easily detached from the hook 2 along the insertion direction.
[0043] In this embodiment, it is preferred that the retaining pin 34 is a type-b split pin 34 (a standard part in the prior art), so that it is more convenient to install the retaining pin 34 on the pin shaft 33.
[0044] The implementation principle of the concrete pouring device in the embodiment of the present application is as follows: when the limiting rod 22 is fixed after covering the hanging opening 21, then insert the pin shaft 33 into the through hole 221 and the mounting hole 222 and then insert the retaining pin 34 into the pin hole 331. Therefore, when disassembling, there is no need to bring tools such as wrenches, making the disassembly and assembly of the chute 1 more convenient.
[0045] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
