Description

Technical Field

[0001] This utility model relates to the field of bored pile technology, specifically to an underwater concrete over-pouring control device for bored piles. Background Technology

[0002] Drilled piles have mature construction technology and high bearing capacity, and are suitable for foundations of various geological soil layers. They have been widely used in the structural foundations of buildings, municipal public works, highways, waterways, railways, water conservancy and other engineering projects.

[0003] According to the public announcement of an underwater concrete over-pouring control device for bored piles (Announcement No.: CN208668423U), the above-mentioned application is easy to manufacture, has low manufacturing cost, and is reusable. This application is easy to operate on the construction site, can be used in most geological soil layers, has a wide range of applications, and a long service life; it achieves the purpose of reducing the cost of underwater concrete pouring and subsequent pile head removal.

[0004] However, in actual use, the above-mentioned equipment is difficult to observe the over-pouring of underwater concrete piles when the water is relatively turbid. The existing equipment relies on a long rod with scales to monitor the over-pouring of concrete. The end of the rod can easily penetrate into the concrete, which makes the scale on the rod unable to accurately reflect the height of the concrete, making it difficult to control the over-pouring. In view of this, we propose an underwater concrete over-pouring control device for bored piles. Utility Model Content

[0005] The purpose of this invention is to provide a device for controlling underwater concrete over-pouring in bored piles, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a control device for underwater concrete over-pouring in bored piles, comprising a fixed base, a wire passing through and fixedly connected to the inner wall of the fixed base, an alarm module electrically connected to one end of the wire passing through the inner wall of the fixed base, a pressure sensor fixedly connected to the other end of the wire away from the fixed base, a support plate fixedly connected to the other end of the pressure sensor away from the wire, and a lifting assembly disposed inside the fixed base, the lifting assembly comprising:

[0007] A rotating block is rotatably connected to the outer wall of a fixed base. A gear is fixedly connected to the outer wall of the rotating block. A locking block is slidably connected to the inner wall of the fixed base. A spring is fixedly connected to the outer wall of the locking block.

[0008] A telescopic rod is fixedly connected to the outer wall of the rotating block. A sleeve is fixedly connected to the end of the telescopic rod away from the rotating block. A connecting rod is slidably connected through the inner wall of the sleeve. A roller is rotatably connected to the outer wall of the connecting rod.

[0009] Preferably, the housing is provided with a fixing component inside. The fixing component includes a threaded hole on the outer wall of the housing. A bolt is threaded to the inner wall of the threaded hole. A pressure block is fixedly connected to the lower outer wall of the bolt. A baffle is fixedly connected to the end of the connecting rod away from the roller. After the connecting rod moves on the housing, the bolt can be rotated to make the pressure block press down on the connecting rod, making it difficult for the connecting rod to move, thereby fixing the position of the roller.

[0010] Preferably, the inner and outer walls of the pressure block are provided with arc grooves, the curvature of the arc grooves is consistent with the curvature of the connecting rod, and a friction pad is fixedly connected to the inner wall of the arc grooves. The arc grooves fit against the outer wall of the connecting rod. When the bolt drives the pressure block to press the connecting rod, the friction pad contacts the connecting rod, making the friction between the connecting rod and the pressure block greater, thereby making the connecting rod more stable, and thus making the position of the roller more stable.

[0011] Preferably, the gap between the locking block and the gear teeth is consistent, the locking block engages with the gear, and the end of the spring away from the locking block is fixedly connected to the inner wall of the fixed base. After the rotating block rotates, the gear rotates accordingly, and the locking block is pushed by the spring so that the locking block can lock the gear, thus fixing the gear. This fixes the rotation angle of the rotating block and the rotation angle of the telescopic rod, allowing the wire to pass through the roller to suspend the pressure sensor into the water.

[0012] Preferably, the output terminal of the pressure sensor is electrically connected to the wire, and the sensing end of the pressure sensor is located at the end of the pressure sensor away from the wire. When the pressure sensor is suspended in water, and the concrete pile is poured until it reaches the designated position, the concrete will push up the sensing end of the pressure sensor, so that the sensing end of the pressure sensor can be subjected to pressure. The pressure sensor has a threshold value set inside. When the concrete pushes up the sensing end of the pressure sensor, the sensing end of the pressure sensor emits an electrical signal. The electrical signal is conducted to the alarm module by the wire, so that the alarm module can issue an alarm.

[0013] Preferably, the outer wall of the roller has a groove, the width of which is the same as the diameter of the wire, and the depth of which is greater than the diameter of the wire. When the wire is placed in the groove, it can pass around the roller and allow the wire pressure sensor to be poured into the water, so that the pressure sensor can be better suspended in the water and kept away from the ground.

[0014] Preferably, the outer wall of the casing has a groove matching the diameter of the connecting rod, the connecting rod passes through the groove and is slidably connected to the inner wall of the groove, and the diameter of the baffle is larger than the diameter of the groove, so that the baffle can block the connecting rod when it moves on the casing.

[0015] Compared with the prior art, this utility model provides a device for controlling underwater concrete over-pouring in bored piles, which has the following beneficial effects:

[0016] 1. This underwater concrete over-pouring control device for bored piles extends the telescopic rod, moving its end above the concrete pile. Then, the connecting rod is moved to bring the roller level with the guide wire. The guide wire is then passed around the roller to lower the pressure sensor into the water to a designated position. When over-pouring reaches the designated position, the sensing end of the pressure sensor receives pressure from the concrete. The pressure sensor then sends an electrical signal to trigger an alarm, allowing the user to control the over-pouring of concrete in a timely manner.

[0017] 2. The underwater concrete over-pouring control device for bored piles allows the connecting rod to move on the casing, and the rotatable bolts to press the connecting rod down. At this time, the friction pad contacts the connecting rod, increasing the friction between the connecting rod and the pressure block, thereby fixing the position of the roller and keeping it flush with the guide wire. This allows the pressure sensor to better extend into the water to control the over-pouring concrete. Attached Figure Description

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: an underwater concrete over-pouring control device for bored piles, including a fixed base 1, a wire 2 passing through and fixedly connected to the inner wall of the fixed base 1, an alarm module 3 electrically connected to one end of the wire 2 passing through the inner wall of the fixed base 1, a pressure sensor 4 fixedly connected to one end of the wire 2 away from the fixed base 1, a support plate 5 fixedly connected to one end of the pressure sensor 4 away from the wire 2, and a lifting assembly 6 provided inside the fixed base 1, the lifting assembly 6 including a rotating block 61, a gear 62, a locking block 63, a spring 64, a telescopic rod 65, a sleeve 66, a connecting rod 67, and a roller 68.

[0024] In one embodiment of the present invention, the rotating block 61 is rotatably connected to the outer wall of the fixed base 1, the outer wall of the rotating block 61 is fixedly connected to the gear 62, the inner wall of the fixed base 1 is slidably connected to the locking block 63, and the outer wall of the locking block 63 is fixedly connected to the spring 64.

[0025] In one embodiment of the present invention, the telescopic rod 65 is fixedly connected to the outer wall of the rotating block 61, and a sleeve 66 is fixedly connected to the end of the telescopic rod 65 away from the rotating block 61. A connecting rod 67 is slidably connected through the inner wall of the sleeve 66, and a roller 68 is rotatably connected to the outer wall of the connecting rod 67.

[0026] In addition, a fixing component 7 is provided inside the casing 66. The fixing component 7 includes a threaded hole 71, which is opened on the outer wall of the casing 66. A bolt 72 is threadedly connected to the inner wall of the threaded hole 71. A pressure block 73 is fixedly connected to the lower outer wall of the bolt 72. A baffle 74 is fixedly connected to the end of the connecting rod 67 away from the roller 68. After the connecting rod 67 moves on the casing 66, the bolt 72 can be rotated to make the pressure block 73 press down on the connecting rod 67, making it difficult for the connecting rod 67 to move. This fixes the position of the roller 68, allowing the pressure sensor 4 to better extend into the water to control the over-poured concrete.

[0027] In this embodiment of the invention, the inner and outer walls of the pressure block 73 are provided with arc grooves, the curvature of which is consistent with that of the connecting rod 67. A friction pad is fixedly connected to the inner wall of the arc groove, and the arc groove fits against the outer wall of the connecting rod 67. When the bolt 72 drives the pressure block 73 to press the connecting rod 67, the friction pad contacts the connecting rod 67, making the friction between the connecting rod 67 and the pressure block 73 greater, thereby making the connecting rod 67 more stable, and thus making the position of the roller 68 more stable, so that the wire 2 can stably suspend the pressure sensor 4 into the water.

[0028] In this embodiment of the utility model, the gap between the locking block 63 and the gear 62 is consistent, the locking block 63 and the gear 62 are engaged, and the end of the spring 64 away from the locking block 63 is fixedly connected to the inner wall of the fixed base 1. After the rotating block 61 rotates, the gear 62 rotates accordingly. The locking block 63 is pushed by the spring 64 so that the locking block 63 can lock the gear 62, so that the gear 62 is fixed. Thus, the rotation angle of the rotating block 61 can be fixed, the rotation angle of the telescopic rod 65 can be fixed, and the wire 2 can pass through the roller 68 to suspend the pressure sensor 4 into the water, so that the position of the pressure sensor 4 in the water can be kept stable.

[0029] In this embodiment of the invention, the output end of the pressure sensor 4 is electrically connected to the wire 2. The sensing end of the pressure sensor 4 is located at the end of the pressure sensor 4 furthest from the wire 2. The pressure sensor 4 is suspended in water. When the concrete pile is poured until it exceeds the designated position, the concrete pushes up the sensing end of the pressure sensor 4, so that the sensing end of the pressure sensor 4 can be subjected to pressure. The pressure sensor 4 has a threshold value inside. When the concrete pushes up the sensing end of the pressure sensor 4, the sensing end of the pressure sensor 4 emits an electrical signal. The electrical signal is transmitted to the alarm module 3 by the wire 2, so that the alarm module 3 can issue an alarm, so that the user can control the concrete pouring in time and prevent the over-poured concrete from exceeding the designated position.

[0030] In an embodiment of this utility model, the outer wall of the roller 68 is provided with a groove. The width of the groove is the same as the diameter of the wire 2, and the depth of the groove is greater than the diameter of the wire 2. When the wire 2 is placed in the groove, the wire 2 passes around the roller 68 and can be poured into the water, so that the pressure sensor 4 can be better suspended in the water, and the pressure sensor 4 can be kept away from the ground, preventing the wire 2 from rubbing against the ground, and shortening the service life of the wire 2.

[0031] In an embodiment of this utility model, the outer wall of the housing 66 is provided with a groove that matches the diameter of the connecting rod 67. The connecting rod 67 passes through the groove and is slidably connected to the inner wall of the groove. The diameter of the baffle 74 is larger than the diameter of the groove. When the connecting rod 67 moves on the housing 66, the baffle 74 can block the connecting rod 67 so that the connecting rod 67 will not fall out of the housing 66.

[0032] In this invention, during use, rotating the rotating block 61 causes the telescopic rod 65 to rotate, then extending the telescopic rod 65 so that its end moves above the concrete pile. Next, moving the connecting rod 67 causes the roller 68 to move flush with the conductor 2. Then, the conductor 2 is passed around the roller 68 to lower the pressure sensor 4 into the water to a designated position. When overfilling reaches the designated position, the sensing end of the pressure sensor 4 receives pressure from the concrete. At this time, the sensing end of the pressure sensor 4 emits an electrical signal, which is transmitted to the alarm module 3 via the conductor 2, causing the alarm module 3 to sound an alarm. This allows the user to control the concrete pouring in a timely manner, preventing overfilled concrete from exceeding the designated position. After the connecting rod 67 moves on the housing 66, the rotatable bolt 72 causes the pressure block 73 to press down on the connecting rod 67. At this time, the friction pad contacts the connecting rod 67, increasing the friction between the connecting rod 67 and the pressure block 73, thereby fixing the position of the roller 68 and ensuring that the roller 68 is flush with the conductor 2. This allows the pressure sensor 4 to better extend into the water to control overfilled concrete.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
