Description

Technical Field

[0001] The utility model relates to the technical field of immersed tube devices, and particularly relates to an immersed tube device for plain concrete piles. Background Technique

[0002] Plain concrete piles are bearing piles for medium and small-sized projects with relatively low pile foundation bearing capacity requirements, and have the advantages of convenient operation and steel saving. Usually, the production site of plain concrete piles is the construction site. First, a hole is drilled to the required depth, and then concrete is poured into the hole. After tamping, it becomes a plain concrete pile. Therefore, plain concrete piles have the characteristic of steel saving.

[0003] Based on the actual application of plain concrete piles, sometimes underwater construction is required, and the immersed tube method needs to be used for underwater construction. The immersed tube method is an underwater construction method to sink plain concrete piles to designated positions such as the bottom of a water area or a river, and a hoisting machine is used to lift and use plain concrete piles during operation.

[0004] The lifting of plain concrete piles uses a hoisting machine. At present, when a small hoisting machine is used to sink or lift an underwater plain concrete pile from the shore, there are problems of insufficient lifting distance and lifting height. Content of the Utility Model

[0005] The utility model provides an immersed tube device for plain concrete piles, which increases the lifting height and distance of the hoisting machine, and facilitates the sinking and lifting of plain concrete piles.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0007] An immersed tube device for plain concrete piles includes a base fixed on the ground. An elevating platform is arranged above the base, and the elevating platform is fixedly connected with a movable block; one end of a screw rod is rotatably connected to the base, and the screw rod passes through the movable block and is threadedly connected with the movable block. One end of a guide rod is fixedly installed on the base, and the guide rod passes through the movable block and is slidably connected with the movable block. The screw rod is connected with a driving motor; a winch is installed on the elevating platform. The steel wire rope of the winch passes around a first roller and a second roller and then is connected with a mechanical claw; a vertical cushion plate is installed on the elevating platform. The first roller is installed on the top of the cushion plate, and the second roller is connected to the side of the cushion plate through a horizontal electric push rod.

[0008] Further, the bottom of the elevating platform is connected with an adapter plate through a telescopic sleeve. A spring is sleeved outside the telescopic sleeve. One end of the spring is fixedly connected to the bottom of the elevating platform, and the other end of the spring is fixedly connected to the adapter plate; a buffer pad is installed at the bottom of the adapter plate.

[0009] Preferably, the buffer pad is hemispherical, and the arc surface of the buffer pad is arranged downward.

[0010] Preferably, there are two telescopic sleeves and springs. The telescopic sleeves are respectively installed at the horizontal two ends of the connecting plate, and the two telescopic sleeves are symmetrically arranged along the connecting plate.

[0011] Furthermore, an infrared position sensor is installed on the mechanical claw.

[0012] Furthermore, an adjustment box is installed on the base. The screw rod, the guide rod and the movable block are installed in the adjustment box, and a guide groove is arranged on the side of the adjustment box; one end of the movable block passes through the adjustment box and is connected to the screw rod and the guide rod, and the other end is located outside the adjustment box and is connected to the lifting platform; the driving motor is fixedly installed on the top of the adjustment box, and the output end of the driving motor is arranged downward and connected to the screw rod.

[0013] Preferably, the driving motor is a servo motor.

[0014] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0015] The hoisting height and distance of the hoisting machinery are increased, which is convenient for the sinking and hoisting of the plain concrete pile. The height adjustment is completed by the screw rod and the guide rod on the base. The screw rod is controlled by the driving motor, and the guide rod is slidably connected to the movable block to limit the movable block. The rotation of the screw rod makes the movable block rise or fall along the axial direction of the screw rod, and then the lifting platform connected to the movable block, as well as the winch, the steel wire rope and the mechanical claw on the lifting platform, rise or fall synchronously to complete the height adjustment. The hoisting distance of the mechanical claw is adjusted by the electric push rod in the horizontal direction. During the process of the electric push rod pushing outwards, the force-bearing fulcrum of the steel wire rope is moved outwards, increasing the hoisting distance of the mechanical claw.

Detailed Embodiments

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model, so as to have a further understanding of the concept of the present utility model, the technical problems to be solved, the technical features constituting the technical solutions, and the technical effects brought about.

[0021] As Figure 1 and Figure 3 shown, a pipe sinking device for a plain concrete pile includes a base 1 fixed on the ground. An elevating platform 7 is arranged above the base 1, and the elevating platform 7 is fixedly connected with a movable block 4. One end of a screw rod 3 is rotatably connected to the base 1, and the screw rod 3 passes through the movable block 4 and is threadedly connected with the movable block 4. One end of a guide rod 2 is fixedly installed on the base 1, and the guide rod 2 passes through the movable block 4 and is slidably connected with the movable block 4. The screw rod 3 is connected with a driving motor. A winch 8 is installed on the elevating platform 7. The steel wire rope 10 of the winch 8 is connected with a mechanical claw 14 after passing around a first roller 11 and a second roller 12. A vertical backing plate 9 is installed on the elevating platform 7. The first roller 11 is installed at the top of the backing plate 9, and the second roller 12 is connected to the side of the backing plate 9 through a horizontal electric push rod 13.

[0022] In the current pipe sinking method, when using a small hoisting machine to sink or lift a plain concrete pile underwater from the shore, there are problems of insufficient hoisting distance and hoisting height. The improvement point of the present utility model is to increase the hoisting height and distance of the hoisting machine, which is convenient for sinking and lifting the plain concrete pile. The hoisting part of the present utility model adopts a winch 8, a steel wire rope 10 and a mechanical claw 14. The mechanical claw 14 grabs, and after hoisting by the winch 8 and the steel wire rope 10, it is used for pipe sinking or lifting. The adjustment of the height is completed by the screw rod 3 and the guide rod 2 on the base 1. The screw rod 3 is controlled by a driving motor. After the guide rod 2 is slidably connected with the movable block 4, it restricts the movable block 4. The rotation of the screw rod 3 makes the movable block 4 rise or fall along the axial direction of the screw rod 3, and further makes the elevating platform 7 connected to the movable block 4 and the winch 8, the steel wire rope 10 and the mechanical claw 14 on the elevating platform 7 rise or fall synchronously, completing the adjustment in height. The hoisting distance of the mechanical claw 14 is adjusted by the horizontal electric push rod 13. During the process of the electric push rod 13 pushing outwards, the force bearing point of the steel wire rope 10 is moved outwards, increasing the hoisting distance of the mechanical claw 14, and the first roller 11 supports the main gravity of the mechanical claw 14 and the plain concrete pile connected by the steel wire rope 10 upwards, avoiding the bending problem caused by excessive pressure at the second roller 12.

[0023] As Figure 2As shown, further, the bottom of the lifting platform 7 is connected to an adapter plate 16 through a telescopic sleeve 17. A spring 18 is sleeved outside the telescopic sleeve 17. One end of the spring 18 is fixedly connected to the bottom of the lifting platform 7, and the other end of the spring 18 is fixedly connected to the adapter plate 16; a buffer pad 19 is installed at the bottom of the adapter plate 16. During the process of the lifting platform 7 descending to the base 1, since the lifting platform 7 has a plain concrete pile lifted by a winch 8 and a steel wire rope 10, and the weight is relatively large, directly descending to the base 1 will affect the base 1, and even damage the base 1 after long-term use. After the buffer pad 19 is provided, during the process of the buffer pad 19 itself being pressed against the base 1, it can buffer and avoid extrusion and collision through its own deformation, and the telescopic sleeve 17 and the spring 18 can also buffer and avoid collision through their own vertical telescoping.

[0024] Preferably, the buffer pad 19 is hemispherical, and the arc surface of the buffer pad 19 is arranged downward. The hemispherical buffer pad 19 can buffer better.

[0025] Preferably, there are two telescopic sleeves 17 and springs 18. The telescopic sleeves 17 are respectively installed at the horizontal two ends of the adapter plate 16, and the two telescopic sleeves 17 are symmetrically arranged along the adapter plate 16. One telescopic sleeve 17 and one spring 18 are respectively arranged at the horizontal two ends of the adapter plate 16, which can disperse the extrusion force received by the spring 18, and make the adapter plate 16 not easy to tilt during long-term buffer extrusion.

[0026] Further, an infrared position sensor 15 is installed on the mechanical claw 14. The infrared position sensor 15 is provided to detect the plain concrete pile underwater during the lifting process, which is convenient for quickly positioning the plain concrete pile and grasping it.

[0027] Further, an adjustment box 6 is installed on the base 1. The screw rod 3, the guide rod 2 and the movable block 4 are installed in the adjustment box 6, and a guide groove is arranged on the side surface of the adjustment box 6; one end of the movable block 4 passes through the adjustment box 6 and is connected to the screw rod 3 and the guide rod 2, and the other end is located outside the adjustment box 6 and is connected to the lifting platform 7; the driving motor is fixedly installed on the top of the adjustment box 6, and the output end of the driving motor is arranged downward and connected to the screw rod 3. The adjustment box 6 mainly plays a protective role, separating the structures such as the guide rod 2, the screw rod 3 and the movable block 4 that generate a linkage effect during the height adjustment process from the outside world, and ensuring the accuracy during its long-term use.

[0028] Preferably, the driving motor is a servo motor 5. Selecting a more precise servo motor 5 to control the rotation of the screw rod 3 can make the height adjustment more precise.
