Description

Technical Field

[0001] The invention relates to the technical field related to concrete pouring, and in particular to underwater concrete pouring equipment. Background Art

[0002] Underwater concrete pouring is an important construction method widely used in underwater or underground engineering fields. It is mainly used to construct various underwater structures, including but not limited to cofferdams, caisson foundations, caisson foundations, underground continuous walls and pile foundations. This method ensures the stability and durability of underwater structures through precise construction technology and material ratios.

[0003] In the process of underwater concrete pouring, the first pour of concrete plays a vital role. In order to ensure that the first pour of concrete can be poured smoothly and accurately to the target location, the catheter method foam ball pulling pouring technology is usually used. This technology sets a foam ball at the top of the catheter and uses the buoyancy of the foam ball. When the catheter needs to be opened for pouring, the foam ball is pulled to separate it from the top of the catheter, thereby opening the pouring channel. At this time, the underwater concrete can smoothly fall along the catheter to the bottom structure that needs to be poured, completing the first pouring.

[0004] However, this technology also faces some challenges in actual application. Although foam balls have the property of floating in concrete, due to the complexity of the well environment, such as obstacles, water flow disturbances and other factors, the foam balls may be blocked and unable to float normally. This situation will not only cause the water stopper to be unable to be recovered normally, affecting the smooth progress of subsequent pouring, but also the foam balls left in the concrete may also have an adverse effect on the structural integrity of the poured concrete column due to their own volume. Specifically, the presence of foam balls may weaken the overall stiffness of the concrete column, thereby affecting its bearing capacity and service life. Summary of the invention

[0005] The present invention provides an underwater concrete pouring device, which has the advantage that a piston is firmly pulled by a steel wire rope, and is used to solve the problem that the unrestricted foam balls mentioned in the above background technology are easily stuck inside the concrete column.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an underwater concrete pouring equipment, comprising: a hopper, with a conduit fixedly connected to the bottom and a support arm mounted on the top; a power supply assembly and a control console mounted on the support arm; a rotating disk, movably mounted in the middle of the support arm, and a rope drum mounted on the rotating disk, and an intermediate shaft coaxially connected to the rope drum; a winding motor, fastened to the rotating disk, and the winding motor shaft and the intermediate shaft are coaxially fastened; a steel wire rope, the top of which is connected to the rope drum, the bottom of which is connected to a slurry blocking piston, and the slurry blocking piston is sleeved inside the conduit.

[0007] Furthermore, the number of rope drums is two.

[0008] Furthermore, a one-way limit gear is fixedly installed on the outer side of the intermediate shaft, a limit push rod is movable on the surface of the rotating disk, and a limit top spring is connected between the limit push rod and the rotating disk, a release fork is installed on the surface of the rotating disk, and the release fork is located between the limit push rod and the one-way limit gear.

[0009] Furthermore, the top of the slurry retaining piston is fastened with a booster auger, and the bottom of the wire rope is fastened to the top of the booster auger.

[0010] Furthermore, a driven gear is fastened to the outer side of the rotating disk, a driving gear meshing with the outer teeth of the driven gear is movably mounted on the supporting arm, and the driving gear is driven by a booster motor fixed on the supporting arm.

[0011] Furthermore, a cantilever assembly is movably installed at the bottom of the slurry-blocking piston, and a push spring is connected to the cantilever assembly, a support shaft is installed on the cantilever assembly, and a detection roller is mounted on the outside of the support shaft, a limit pin is inserted into the outside of the detection roller, a return spring is connected between the limit pin and the inside of the support shaft, and a starting switch is fixedly installed on the inside of the support shaft. When the starting switch is turned on, the alarm light fixed on the support arm frame can light up.

[0012] Furthermore, the cantilever assembly is composed of a high-position detection cantilever and a low-position detection cantilever, and the difference between the two is that the height of the high-position detection cantilever is 2-5 times the height of the low-position detection cantilever.

[0013] Furthermore, the alarm light is composed of a red indicator light and a green indicator light. The red indicator light is connected in series with a start switch in the high-position detection cantilever, and the green indicator light is connected in series with a start switch in the low-position detection cantilever.

[0014] Furthermore, a protective pipe is connected between the booster auger and the rotating disk.

[0015] The present invention has the following beneficial effects:

[0016] The invention provides underwater concrete pouring equipment, in which a slurry blocking piston is installed inside a conduit, and the slurry blocking piston is connected to a rope drum by a steel wire rope, so as to ensure stability and controllability during the pouring process.

[0017] When pouring the first tank, the construction workers will first lock the rope drum so that the slurry blocking piston can tightly block the bottom of the hopper to prevent concrete from leaking out during the initial pouring. Then, a pre-calculated volume of concrete is injected into the hopper. When the concrete reaches a certain pressure and volume, the construction workers will release the restraining measures on the rope drum. At this time, under the strong pressure of the concrete, the slurry blocking piston will move smoothly downward along the conduit until it reaches the bottom of the conduit.

[0018] When the slurry retaining piston moves to the bottom of the conduit, the concrete in the conduit will be smoothly poured into the pit by gravity. It is worth noting that since the slurry retaining piston is connected to the rope drum by a wire rope, even if the slurry retaining piston moves downward under the pressure of the concrete, it will not be lost in the pit. This design cleverly ensures the stability and recyclability of the slurry retaining piston during the pouring process.

[0019] Finally, through the restriction of the wire rope, the slurry retaining piston can smoothly return to its initial position after completing one pouring, thus realizing the reuse of the slurry retaining piston. This design not only improves the efficiency and reliability of underwater concrete pouring equipment, but also greatly reduces construction costs and time costs, making an important contribution to the development of underwater engineering.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In the process of underwater concrete pouring, the first tank of concrete is very important. The first tank of concrete can squeeze the water medium in the pit, so as to use the water medium to flush the pit. Please refer to Figure 1-Figure 3 It can be seen that the bottom of the hopper 1 is fixedly connected with a conduit 2. In actual arrangement, there are multiple conduits 2, and the multiple conduits 2 are tightened in sequence from head to tail to ensure that the concrete slurry entering the hopper 1 can be poured into the bottom of the pit through the conduit 2. The outside of the hopper 1 is provided with a lifting lug, such as Figure 1 As shown, there are four lifting ears, and their main purpose is to connect the steel rope on the crane so that the guide tube 2 can be vertically inserted into the well pit.

[0032] The support arm 3 is fastened to the top of the hopper 1 by bolts, and the support arm 3 can provide support for subsequent components. Figure 2 and Figure 3 As shown, a rotating disk 6 is movably installed in the middle of the supporting arm 3, and the rotating disk 6 is preferably arranged coaxially with the hopper 1. In addition, the rope drum 8 is fastened to the rotating disk 6 by bolts. Figure 2 It can be clearly seen that there are two rope drums 8, and the two rope drums 8 rotate coaxially through an intermediate shaft 900. Furthermore, the intermediate shaft 900 is driven by a winding motor 9 fixed on the surface of the rotating disk 6. When the winding motor 9 rotates, the steel wire rope 15 fastened to the outer side of the rope drum 8 can be wound. Figure 3It can be seen that for the electrical control of the winding motor 9, the power supply assembly 5 fixed at the bottom of the support arm 3 is used to provide power, and precise control is performed through the control console 14 fixed on one side of the surface of the support arm 3 to ensure that the winding motor 9 can rotate as required.

[0033] The steel wire ropes 15 on the two rope drums 8 are connected to the slurry blocking piston 18 after passing through the bottom of the rotating disk 6. The advantage of this design is that since the slurry blocking piston 18 is mounted inside the conduit 2, the upper and lower end areas of the slurry blocking piston 18 are relatively isolated. The traction of the slurry blocking piston 18 by the steel wire rope 15 can ensure that the slurry blocking piston 18 moves up to the specified position. When used, the steel wire rope on the crane is used to drive the conduit 2 to be vertically inserted into the pit, and the concrete slurry is discharged into the hopper 1 by a tank truck. During this process, the steel wire rope 15 is wound by the rope drum 8, so that the concrete accumulates in the area above the slurry blocking piston 18. After the required amount of concrete is placed in the hopper 1, the slurry blocking piston 18 is released by the winding motor 9 until the slurry blocking piston 18 moves to the bottom of the conduit 2, so that the concrete in the conduit 2 is poured into the pit from its bottom. Subsequently, as the crane continuously pulls the hopper 1 upward, the tank truck continuously delivers concrete into the conduit 2, so that the concrete in the conduit 2 is continuously discharged into the pit, thereby completing the pouring of the concrete column in the pit.

[0034] On this basis, when there is too much concrete slurry in the hopper 1, the pressing force on the slurry blocking piston 18 is relatively increased, which easily causes the slurry blocking piston 18 to be forced to detach from the rope drum 8 by dragging the wire rope 15, thereby Figure 3 and Figure 4 It can be seen that a one-way limit gear 10 is fixedly mounted on the outer side of the intermediate shaft 900, and correspondingly, a limit push rod 25 is movable on the surface of the rotating disk 6 and is pushed upward by a limit push spring 250. When the limit push rod 25 reaches the outer side of the one-way limit gear 10, it can limit the one-way limit gear 10 from rotating in one direction. The cross-section shape of the central axis of the limit push rod 25 is in the shape of a "cross", combined with Figure 4 It can be seen that a release fork 11 is hinged on the surface of the rotating disk 6, and the release fork 11 is located between the limit push rod 25 and the one-way limit gear 10. Specifically, when the winding motor 9 drives the rope drum 8 to wind up, the rope drum 8 causes the steel wire rope 15 to move upward by winding up, and pulls the slurry blocking piston 18 to move upward synchronously. In this process, due to the one-way transmission between the one-way limit gear 10 and the limit push rod 25, the limit push rod 25 will not prevent the rotation of the one-way limit gear 10; when the tank truck injects concrete slurry into the hopper 1, the pressure on the top of the slurry blocking piston 18 increases, so that the rope drum 8 tends to move downward by dragging the steel wire rope 15. In this process, the rope drum 8 tends to rotate in the opposite direction through the intermediate shaft 900, and the limit push rod 25 limits the reverse rotation of the one-way limit gear 10 (i.e. Figure 4 The one-way limit gear 10 cannot rotate clockwise), so that the one-way limit gear 10 cannot rotate, the rope drum 8 will not release the wire rope 15, and the slurry blocking piston 18 will be suspended at the set position. When it is necessary to release the concrete in the hopper 1, the operator applies downward pressure to the release stop fork 11, forcing the release stop fork 11 to contact the limit push rod 25 and press the limit top spring 250 downward, and finally the limit push rod 25 and the one-way limit gear 10 are disengaged, thereby releasing the rotation restriction of the one-way limit gear 10.

[0035] Since the bottom of the conduit 2 is always inserted into the concrete of the pit, a pressure difference is generated between the concrete inside the conduit 2 and the pit, so that the concrete in the conduit 2 is pressed into the pit under the action of the pressure difference, thereby ensuring the pouring quality of the concrete. In order to increase the strength of the concrete in the conduit 2 being transported to the pit, the concrete in the conduit 2 is combined with the pressure difference. Figure 3 It can be seen that the top of the slurry-blocking piston 18 is fastened with a booster auger 17, and the outer side of the booster auger 17 is slidably connected to the inner side of the conduit 2. Moreover, the bottoms of the two steel wire ropes 15 are fastened to the top of the booster auger 17. When the rope drum 8 completely releases the steel wire rope 15, the slurry-blocking piston 18 extends from the bottom of the conduit 2, but the booster auger 17 is located at the inner bottom of the conduit 2. The booster auger 17 can be used to limit the slurry-blocking piston 18 to ensure that the slurry-blocking piston 18 is still coaxial with the conduit 2 after extending out of the conduit 2. This can ensure that the slurry-blocking piston 18 extending from the bottom of the conduit 2 will not move around and cause accidental jamming. At the same time, combined with Figure 3 and Figure 4 It can be seen that the outer side of the rotating disk 6 is fastened with a driven gear 7, and correspondingly, a driving gear 12 meshing with the outer teeth of the driven gear 7 is movably installed on the support arm 3. The driving gear 12 is driven by a booster motor 13 fixed on the support arm 3. The booster motor 13 is also provided with power by the power supply assembly 5 and is regulated by the control console 14. Therefore, during the concrete pouring process, when the release fork 11 is pressed, the first tank of concrete in the hopper 1 moves downward rapidly by pressing the slurry blocking piston 18, and finally the slurry blocking piston 18 moves to the bottom of the conduit 2. At the same time, the concrete in the conduit 2 is poured into the pit under the action of gravity. In this process, the booster motor 13 is controlled to rotate by the control console 14, forcing the driving gear 12 to drive the driven gear 7 to rotate synchronously. Since the top of the booster auger 17 is driven by two steel wires 15, when the driven gear 7 drives the rotating disk 6 to rotate, the rotating disk 6 drives the two steel wires 15 to rotate, further causing the booster auger 17 and the slurry blocking piston 18 to rotate synchronously. The booster auger 17 rotates to rapidly release the concrete slurry in the inner cavity of the conduit 2, thereby accelerating the pouring of the concrete slurry in the conduit 2 into the well pit.

[0036] Although the above-mentioned method can enhance the pouring of concrete in the conduit 2 into the well pit, it is common sense that when the two steel ropes 15 rotate, if the resistance of the booster auger 17 is too large, the steel ropes 15 will be entangled with each other, forcing the booster auger 17 to tend to pull upward, causing the slurry-blocking piston 18 to move upward and causing the bottom of the conduit 2 to tend to be blocked, which is obviously not conducive to the pouring of concrete slurry. In addition, because the concrete slurry enters the bottom of the initially poured concrete through the sealed conduit under a certain drop pressure, it gradually rises with the initially poured concrete and the water medium above it, forming a continuous and dense concrete pile body. As the amount of concrete poured increases, the conduit is lifted, and the height of each lifting of the conduit is manually controlled, which cannot accurately reflect the height of the concrete pouring. Quality problems such as broken piles, pipe blockage, and mud inclusions often occur due to improper construction technology. In order to prevent the occurrence of such problems, combined with Figure 2 , Figure 3 , Figure 5 and Figure 6 It can be clearly seen that there is a cantilever assembly 19 movably installed through a dovetail groove at the bottom of the slurry-blocking piston 18. The cantilever assembly 19 is generally composed of a high-position detection cantilever 190 and a low-position detection cantilever 191. The two have the same structure, and the only difference is that the height of the high-position detection cantilever 190 is 2-5 times the height of the low-position detection cantilever 191. A push spring 20 is connected between the high-position detection cantilever 190 and the low-position detection cantilever 191. Under the push of the elastic force of the push spring 20, the high-position detection cantilever 190 and the low-position detection cantilever 191 always tend to move away from each other under normal conditions. Figure 5 As shown, a cylindrical hole is provided between the bottom of the high-position detection cantilever 190 and the bottom of the low-position detection cantilever 191. When the bolt passes through the cylindrical hole, the other end of the bolt is tightened by a screw, which can force the high-position detection cantilever 190 and the low-position detection cantilever 191 to approach each other, thereby compressing the push spring 20, making it easier for the two to be retracted from the catheter 2 later. A support shaft 21 is movably installed on the top of the outer side of the high-position detection cantilever 190 and the low-position detection cantilever 191, and a detection roller 22 is mounted on the outer side of the support shaft 21. Furthermore, a limit pin 220 passing through the middle of the support shaft 21 is inserted into the outer side of the detection roller 22, and a return spring 23 is connected between the limit pin 220 and the inside of the support shaft 21. Under the push of the elastic force of the return spring 23, the detection roller 22 always tends to move toward one end of the support shaft 21. A starting switch 24 located on one side of the return spring 23 is fixedly installed on the inner side of the support shaft 21. When the limit pin 220 compresses the return spring 23 and approaches the starting switch 24, the starting switch 24 is turned on to enable the alarm light 4 fixed on the support arm 3 to illuminate, which is used to indicate that the bottom of the conduit 2 is at the position of the pit concrete.

[0037] More specifically, the warning light 4 is composed of a red indicator light 400 and a green indicator light 401, wherein the red indicator light 400 is connected in series with the start switch 24 in the high position detection cantilever 190, and the green indicator light 401 is connected in series with the start switch 24 in the low position detection cantilever 191. When the start switch 24 is pressed, the corresponding red indicator light 400 / green indicator light 401 lights up. Figure 2 and Figure 3 It can be clearly seen that a protective tube 16 is connected between the booster auger 17 and the rotating disk 6. The protective tube 16 is preferably a telescopic tube or a rubber protective tube, and an electric wire for connecting the power supply component 5 and the starting switch 24 is arranged inside the protective tube, so as to ensure that the power supply component 5 can supply power to the starting switch 24, and after the starting switch 24 is turned on, the red indicator light 400 / green indicator light 401 connected in series therewith can light up.

[0038] The working process of the present invention refers to Figure 7 As shown in the first picture on the left, under normal conditions, the control console 14 controls the winding motor 9 to rotate, and the intermediate shaft 900 is used to make the two rope drums 8 simultaneously wind up the wire rope 15. The wire rope 15 pulls the slurry blocking piston 18 upward through the booster auger 17, and the slurry blocking piston 18 is used to block the opening at the bottom of the hopper 1. At this time, the limit push rod 25 is pushed against the one-way limit gear 10 by the elastic force of the limit top spring 250, thereby limiting the reverse rotation of the one-way limit gear 10.

[0039] The crane uses a steel wire rope to vertically place the conduit 2 into the pit, and uses a tank truck to input concrete slurry into the hopper 1. When the first tank of concrete in the hopper 1 reaches a certain volume, the release fork 11 is pulled downward, and with the help of the lever principle, the release fork 11 easily presses the limit push rod 25 downward and compresses the limit top spring 250, and the limit push rod 25 releases the rotation restriction on the one-way limit gear 10. After that, the concrete in the hopper 1 presses the slurry blocking piston 18 downward and moves downward quickly, and the slurry blocking piston 18 squeezes the water medium in the conduit 2 and quickly impacts the bottom of the pit, thereby achieving flushing in the pit.

[0040] As the slurry blocking piston 18 continues to move downward, until the slurry blocking piston 18 and the cantilever assembly 19 are separated from the bottom of the conduit 2, Figure 7 As shown in the intermediate state diagram, during this process, the concrete in the conduit 2 is poured into the pit, and under the action of the pressure difference, the concrete in the pit continues to rise. Afterwards, the operator drives the winding motor 9 to rotate through the console 14, Figure 7 It can be seen from the figure that when the cantilever assembly 19 is away from the bottom of the hopper 1, the high-position detection cantilever 190 and the low-position detection cantilever 191 are forced to move away from each other under the elastic force of the push spring 20. When the rope drum 8 winds up the wire rope 15, the upward slurry blocking piston 18 causes the push spring 20 to push against the bottom of the conduit 2. Figure 7As shown in the rightmost state diagram, as the push spring 20 is pressed, the high-position detection cantilever 190 and the low-position detection cantilever 191 are relatively close to each other until they are attached to the outside of the bottom of the conduit 2. The push spring 20 blocks the slurry blocking piston 18 from moving upward, and the rope drum 8 cannot reel in the wire rope 15. Afterwards, the reeling motor 9 is stopped through the control console 14 and the booster motor 13 is turned on.

[0041] Afterwards, when the boost motor 13 rotates, the driving gear 12 is forced to drive the driven gear 7 to rotate. When the rotating disk 6 on the driven gear 7 drives the wire rope 15 to rotate relatively, the boost auger 17 is finally rotated. During this process, even if the wire ropes 15 are entangled with each other, the slurry blocking piston 18 still cannot move upward because the push spring 20 reaches the bottom of the conduit 2. Finally, when the wire rope 15 rotates, the boost auger 17 is synchronously rotated, and the rotating boost auger 17 drives the slurry blocking piston 18 and the cantilever assembly 19 to rotate synchronously.

[0042] When the booster auger 17 rotates, the concrete at the bottom of the conduit 2 will be quickly poured into the pit, thereby increasing the concrete injection strength. When the slurry blocking piston 18 drives the cantilever assembly 19 to rotate, the end of the detection roller 22 will be blocked by the medium in the pit, thereby timely squeezing the reset spring 23. Specifically, Figure 7 As shown in the rightmost figure, in a normal state, the detection roller 22 on the high-position detection cantilever 190 is in the water medium layer, and the detection roller 22 in the detection roller 22 is in the concrete layer. Since the water medium and the concrete have different resistances to the end of the detection roller 22, when the high-position detection cantilever 190 and the low-position detection cantilever 191 simultaneously follow the rotation of the slurry blocking piston 18, the end of the detection roller 22 in the concrete layer is subjected to a greater pressure, thereby compressing the reset spring 23 and turning on the start switch 24, and the green indicator light 401 corresponding to the start switch 24 is turned on; similarly, since the detection roller 22 in the high-position detection cantilever 190 is in the water medium layer, when the high-position detection cantilever 190 drives the detection roller 22 to rotate, the resistance of the water medium is not enough to push the detection roller 22 to compress the reset spring 23. At this time, the red indicator light 400 will not light up.

[0043] As the tank truck continuously pours concrete into the hopper 1, the concrete at the bottom of the conduit 2 will be continuously injected into the pit. After the height of the concrete in the pit increases, when the concrete layer approaches the detection roller 22 on the high-position detection cantilever 190, the resistance of the detection roller 22 on the high-position detection cantilever 190 increases, thereby forcing the detection roller 22 to compress the reset spring 23, so that the start switch 24 is turned on and the red indicator light 400 is illuminated. When the operator sees that the red indicator light 400 is illuminated, it is necessary to control the crane to pull the conduit 2 upward to ensure that the bottom of the conduit 2 is within the optimal grouting stroke. Finally, when the conduit 2 moves upward, the detection roller 22 on the high-position detection cantilever 190 enters the water medium layer again, so that the red indicator light 400 no longer illuminates. After that, the cycle is repeated in sequence, so that the bottom of the conduit 2 is always kept in the optimal grouting range for operation.
