Description

Technical Field

[0001] This utility model belongs to the technical field of engineering construction, and specifically relates to a concrete pouring device for engineering construction. Background Technology

[0002] In recent years, when pouring concrete into the interior of a building, multiple tremie pipes are usually connected together, and the mixed concrete is poured into the bottom of the building through the tremie pipes by a mixer truck, which helps to complete the foundation construction.

[0003] Currently, concrete is vertically poured using a tremie pipe. As the concrete passes through the inner wall of the tremie pipe, the liquid adheres to the inner wall. Prolonged adhesion causes the concrete to solidify, which in turn reduces the inner diameter of the tremie pipe and further affects the efficiency of the concrete passing through the inside of the tremie pipe. Utility Model Content

[0004] The purpose of this utility model is to provide a concrete pouring device for engineering construction, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An engineering construction concrete pouring device includes auxiliary components, including a tremie pipe. Four outer plates are fixedly connected to the arc surface of the tremie pipe, with the four outer plates arranged in pairs. A rotating plate is rotatably connected to the side of each pair of outer plates that are close to each other. A striking rod is fixedly connected to the upper side of the rotating plate. A guiding assembly is provided on the inner wall of the tremie pipe. A driving assembly is provided between the tremie pipe and the rotating plate. A reset assembly is provided on the outer surface of the outer plates. An impact component includes two connecting frames fixedly connected to the arc surface of the tremie pipe. Seven metal rods are slidably connected to the surface of the connecting frames. A power assembly is provided between the connecting frames and the metal rods.

[0007] As a preferred embodiment of this utility model, the guiding assembly includes two inner plates fixedly connected to the inner wall of the spool, and guide rings are slidably connected to the surfaces of the two inner plates. Rollers are rotatably connected to the upper side of the rotating plate.

[0008] In a preferred embodiment of this utility model, the driving assembly includes a driving plate slidably connected to the lower side of the rotating plate, a force-bearing plate fixedly connected to the surface of the driving plate, a support plate rotatably connected to the lower side of the driving plate, and the lower side of the support plate slidably connected to the string tube.

[0009] In a preferred embodiment of this utility model, the reset assembly includes a rotating shaft rotatably connected to the surface of an outer plate, the rotating shaft being fixedly connected to a rotating plate, and a torsion spring being fitted onto the surface of the rotating shaft, with both ends of the torsion spring being fixedly connected to the outer plate and the rotating shaft, respectively.

[0010] As a preferred embodiment of this utility model, both inner plates are trapezoidal structures with inclined surfaces facing the stringer, and the inner and outer walls of the guide ring are both inclined surfaces that slope inward.

[0011] In a preferred embodiment of this utility model, the upper side of the force-bearing plate and the inner ring of the guide ring are on the same vertical line, and the force-bearing area of ​​the force-bearing plate is greater than the force-bearing area of ​​the rotating plate.

[0012] As a preferred embodiment of this utility model, the power assembly includes a push block slidably connected inside the connecting frame. The lower side of the push block is inclined, and the roller abuts against the inclined surface of the push block. The surfaces of the seven metal rods are rotatably connected to rings, and the arc surfaces of the rings are fixedly connected to a series rod.

[0013] In a preferred embodiment of this utility model, the metal rod slides along inclined grooves on both sides of the connecting frame, and the grooves are of the same length.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Auxiliary components: By using an outer plate and a guide assembly, when concrete is being poured, the outer plate rotates due to contact with the load-bearing plate, which in turn drives the guide ring to move upward. At the same time, the striking rod vibrates against the outer wall of the tremie pipe. Through vibration and the up-and-down movement of the guide ring, concrete blockage in the tremie pipe is prevented, and concrete is also prevented from adhering to the inner wall of the tremie pipe and solidifying.

[0016] 2. By using the impact component and rollers in conjunction with the power assembly, multiple metal rods can be moved upward by the push block while the rotating plate is rotating. As the distance between the metal rods and the tremie drum increases, when the rollers leave the inclined surface of the push block, the metal rods are released from the limit and can strike the surface of the tremie drum in sequence, achieving the effect of multiple vibrations in a short period of time. This further prevents concrete from adhering to the inner wall of the tremie drum and reduces concrete residue. Attached Figure Description

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a concrete pouring device for engineering construction, including auxiliary components, including a tremie pipe 10. Four external plates 11 are fixedly connected to the arc surface of the tremie pipe 10. The four external plates 11 are in pairs. A rotating plate 12 is rotatably connected to the side of each pair of external plates 11 that is close to each other. A striking rod 13 is fixedly connected to the upper side of the rotating plate 12. A guide component 14 is provided on the inner wall of the tremie pipe 10. A drive component 15 is provided between the tremie pipe 10 and the rotating plate 12. A reset component 16 is provided on the outer surface of the external plates 11.

[0028] Multiple ducts 10 can be assembled by hooking the chain on the upper side of the duct 10 with the chain hook on the lower opening. Then, the concrete can be poured down from the uppermost duct 10 to start the pouring operation. The poured concrete, together with the drive component 15, can drive the rotating plate 12 to rotate, so that the striking rod 13 hits the duct 10 and drives the guide component 14, which can effectively assist the clearing and pouring of the concrete inside the duct 10.

[0029] Furthermore, the guiding assembly 14 includes two inner plates 141 fixedly connected to the inner wall of the spool 10. Guide rings 142 are slidably connected to the surfaces of both inner plates 141. A roller 143 is rotatably connected to the upper side of the rotating plate 12. The driving assembly 15 includes a driving plate 151 slidably connected to the lower side of the rotating plate 12. A force-bearing plate 152 is fixedly connected to the surface of the driving plate 151. A support plate 153 is rotatably connected to the lower side of the driving plate 151, and the lower side of the support plate 153 is slidably connected to the spool 10. The resetting assembly 16 includes a rotating shaft 161 rotatably connected to the surface of the outer plate 11. The rotating shaft 161 is fixedly connected to the rotating plate 12. A torsion spring 162 is sleeved on the surface of the rotating shaft 161, and both ends of the torsion spring 162 are fixedly connected to the outer plate 11 and the rotating shaft 161, respectively.

[0030] When the concrete comes into contact with the surfaces of the rotating plate 12 and the force plate 152, it can cause the rotating plate 12 to rotate, which in turn causes the striking rod 13 to strike the outer wall of the cistern 10 and generate vibration. At the same time, it pushes the guide ring 142 upward to help the concrete inside move up and down, reducing the occurrence of blockage. Meanwhile, the torsion spring 162 can help the rotating plate 12 to reset, so that vibration and unblocking effects can be achieved at the same time as the concrete is poured.

[0031] Preferably, both inner plates 141 are trapezoidal structures with inclined surfaces facing the cassette 10, and the inner and outer walls of the guide ring 142 are both inwardly inclined surfaces. The upper side of the force-bearing plate 152 is on the same vertical line as the inner ring of the guide ring 142, and the force-bearing area of ​​the force-bearing plate 152 is greater than the force-bearing area of ​​the rotating plate 12.

[0032] It should be noted that the trapezoidal slope can prevent concrete from accumulating on the upper side of the inner plate 141 and increasing pressure, thus improving the stability of the connection between the inner plate 141 and the inner wall of the tremie cylinder 10. At the same time, the outer slope of the guide ring 142 can be used in conjunction with the roller 143, while the inner slope can guide the concrete, making it less likely for the concrete to contact the inner wall of the lower tremie cylinder 10. It also facilitates the pouring of concrete onto the upper side of the rotating plate 12 and the load-bearing plate 152. Even if the concrete does not contact the rotating plate 12, since the area of ​​the load-bearing plate 152 is larger than that of the rotating plate 12, the impact of the concrete on the load-bearing plate 152 can still drive the rotating plate 12 to rotate.

[0033] In use, multiple cisterns 10 can be connected in series via the chain on the upper side of the cistern 10. The discharge port of the mixer truck is placed on the upper side of the cistern 10, and the mixer truck discharges the concrete, which then works in conjunction with the cistern 10 to complete the pouring operation. When the concrete passes through the inner wall of the cistern 10, it is deflected towards the center by the guide ring 142, eventually contacting the rotating plate 12. This presses down the rotating plate 12, causing it to rotate clockwise. Simultaneously, the roller 143 on the upper side of the rotating plate 12 presses against the outer inclined surface of the guide ring 142, driving the guide ring 142 upwards. This causes the concrete accumulated inside the cistern 10 to move up and down, helping to clear the pushed concrete. At the same time, the rotating plate 12 causes the striking rod 13 to strike the outer wall of the cistern 10, generating vibration. The striking rod 13 also limits the rotation of the rotating plate 12, preventing it from rotating too much and disengaging from the outer inclined surface of the guide ring 142. If the concrete does not contact the rotating plate 12... If the concrete impacts the force plate 152, it will continue to fall downwards and reach an area larger than the force-bearing area of ​​the rotating plate 12. The impact of the concrete on the force plate 152 will still drive the rotating plate 12 to rotate clockwise to complete the knocking and clearing operation. At the same time, the upper side of the drive plate 151 will slide to the right from the lower side of the rotating plate 12, so that the drive plate 151 can be in a position that fits against the inner wall of the tremie drum 10. Meanwhile, the support plate 153 slides down without affecting the normal concrete pouring operation. Since the concrete is poured intermittently when the mixer truck is overturned, it will cause a temporary interruption in the concrete pouring process. At this time, under the action of the torsion spring 162, the rotating plate 12 can be driven to rotate in the opposite direction, so that the roller 143 can be disengaged from the lower inclined surface of the guide ring 142. At the same time, the drive plate 151 and the force plate 152 will be reset. Thus, the knocking and clearing operation can be repeated during concrete pouring, which facilitates the concrete pouring and helps the concrete to be poured from the inner wall of the tremie drum 10 to the pouring position.

[0034] Example 2

[0035] Reference Figures 1-6 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an impact component, including two connecting frames 20 fixedly connected to the arc surface of the cassette 10. Seven metal rods 21 are slidably connected to the surface of the connecting frames 20. A power assembly 22 is provided between the connecting frames 20 and the metal rods 21. The power assembly 22 includes a push block 221 slidably connected inside the connecting frames 20. The lower side of the push block 221 is inclined, and the roller 143 abuts against the inclined surface of the push block 221. The surfaces of the seven metal rods 21 are rotatably connected to a ring 222, and the arc surface of the ring 222 is fixedly connected to a connecting rod 223.

[0036] Specifically, when the rotating plate 12 rotates, it will work with the roller 143 to push the push block 221. The push block 221 abuts against the ring 222. At this time, the push block 221 can work with the ring 222 and the connecting rod 223 to drive multiple metal rods 21 to move upward. Furthermore, when the rotating plate 12 is removed from the underside of the push block 221, the metal rods 21 will slide down and hit the surface of the string drum 10 to produce a vibration effect.

[0037] Preferably, the metal rod 21 slides along the inclined grooves on both sides of the connecting frame 20, and the lengths of the grooves are the same.

[0038] It should be noted that the metal rods 21 slide synchronously, but because the height of the slide groove on the side of the spool 10 is different, the metal rods 21 will hit the surface of the spool 10 at different times, thus producing the effect of multiple impacts.

[0039] When the rotating plate 12 or the force plate 152 is impacted by concrete, it will cause the rotating plate 12 to rotate clockwise. Since the roller 143 abuts against the inclined surface of the push block 221, when the rotating plate 12 rotates, it will push the push block 221 upward through the roller 143. This, in conjunction with the ring 222 and the connecting rod 223, will help multiple metal rods 21 slide upward along the chute at the same time. When the concrete pouring process is paused, the torsion spring 162 will help the rotating plate 12 return to its original position. The upper side of the rotating plate 12 and the roller 143 will disengage from the pressure on the push block 221. At this time, multiple metal rods 21 will slide down under their own weight. Since the surface of the chute 10 is inclined, multiple metal rods 21 will hit the surface of the chute 10 in sequence when they slide down and return to their original position, thereby generating multiple vibrations in a short period of time. This improves the vibration effect and helps the concrete to detach from the inner wall of the chute 10, further improving the anti-adhesion effect on the concrete and reducing the amount of concrete residue on the inner wall of the chute 10.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution 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 solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
