Description

Technical Field

[0001] This utility model relates to the field of pile foundation hole depth measurement technology, and in particular to a pile foundation hole depth measurement device. Background Technology

[0002] In recent years, urban construction has progressed at an increasingly rapid pace, with projects becoming larger and larger, requiring the excavation of more and more pile foundation holes. On-site operators frequently need to measure the depth of these pile foundation holes. Current measurement methods primarily involve using graduated measuring ropes, with a weight suspended at one end, and then a motor used to lay out the measurement line.

[0003] While using a motor to feed the wire improves the measurement speed to some extent, the measuring rope often cannot be evenly wound on the take-up reel during the take-up process. The messy winding of the measuring rope will cause uneven force on the take-up reel. After long-term use, the take-up reel is prone to wear and even deformation, affecting the service life of the equipment and the accuracy of the measurement. At the same time, the messy measuring rope may also cause problems such as jamming and tangling in subsequent measurements, further reducing the measurement speed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pile foundation hole depth measuring device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pile foundation hole depth measuring device includes a base, a driving assembly on the top right side of the base, a reciprocating screw on the top of the base via the driving assembly, a fixed plate rotatably connected to the surface of the reciprocating screw, the fixed plate being fixedly connected to the base, a moving block threadedly connected to the surface of the reciprocating screw, a guide rod slidably connected inside the moving block, the guide rod being fixedly connected to the fixed plate, a moving frame fixedly mounted on the top of the moving block, a take-up reel rotatably connected inside the moving frame, a measuring rope wound on the surface of the take-up reel, a gravity block fixedly mounted at the bottom end of the measuring rope, a transmission assembly on the surface of the reciprocating screw, and a rectangular rod on the top of the reciprocating screw via the transmission assembly, the rectangular rod being slidably connected to the take-up reel.

[0007] Preferably, the drive includes a mounting bracket disposed on the right side of the base, a drive motor is fixedly mounted on the inner wall of the mounting bracket, and the output end of the drive motor is fixedly connected to a reciprocating screw.

[0008] Preferably, the transmission assembly includes a first pulley disposed on the surface of a reciprocating screw, a timing belt meshing on the surface of the first pulley, a second pulley meshing on the inner wall of the timing belt, a rotating shaft fixedly installed inside the second pulley, the rotating shaft being fixedly connected to a rectangular rod, a support frame being rotatably connected to the surface of the rotating shaft, and the support frame being fixedly connected to a base.

[0009] Preferably, a guide tube is fixedly installed inside the base, and the measuring rope is slidably connected to the guide tube.

[0010] Preferably, a rectangular groove is provided through the right side of the take-up reel, and the rectangular rod is slidably connected to the rectangular groove.

[0011] Preferably, the base has a support leg fixedly installed at its bottom, and the number of the support legs is multiple.

[0012] Preferably, the number of the rotating shafts is two, and the two rotating shafts are symmetrically distributed.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the pile foundation hole depth measuring device is taking the line back, the reciprocating screw is rotated by the drive component, and the rotation of the reciprocating screw causes the rectangular rod to rotate through the transmission component, which in turn causes the take-up wheel to rotate and take the measuring rope back. At the same time, the rotation of the reciprocating screw causes the moving block to move left and right along the guide rod, which in turn causes the moving frame to move left and right, and the take-up wheel to move left and right. By making the take-up wheel move back and forth, the measuring rope is evenly wound, which can effectively distribute the force on the take-up wheel during the working process, reduce component wear, reduce equipment maintenance and replacement costs, improve the durability and stability of the equipment, and the evenly wound measuring rope is smoother during the release and take-up process, without problems such as jamming or tangling, which greatly saves measurement time.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1-5A pile foundation hole depth measuring device includes a base 1. A drive assembly is located on the top right side of the base 1. A reciprocating screw 4 is mounted on the top of the base 1 via the drive assembly. The drive assembly includes a mounting frame 2 located on the right side of the base 1. A drive motor 3 is fixedly mounted on the inner wall of the mounting frame 2. The output end of the drive motor 3 is fixedly connected to the reciprocating screw 4. The drive assembly facilitates the provision of driving force for the rotation of the reciprocating screw 4, thereby enabling automatic wire take-up and automatic wire release. A fixing plate 5 is rotatably connected to the surface of the reciprocating screw 4 and is fixedly connected to the base 1. A moving block 6 is threadedly connected to the surface of the reciprocating screw 4, and a sliding connection is made inside the moving block 6. A guide rod 7 is fixedly connected to a fixed plate 5. A movable frame 8 is fixedly installed on the top of a movable block 6. A take-up reel 9 is rotatably connected inside the movable frame 8. A measuring rope 10 is wound on the surface of the take-up reel 9. A gravity block 11 is fixedly installed at the bottom end of the measuring rope 10. A transmission assembly is provided on the surface of a reciprocating screw 4. A rectangular rod 18 is provided on the top of the reciprocating screw 4 through the transmission assembly. The rectangular rod 18 is slidably connected to the take-up reel 9. The transmission assembly includes a first pulley 13 provided on the surface of the reciprocating screw 4. A synchronous belt 14 is meshed on the surface of the first pulley 13. A second pulley 15 is meshed on the inner wall of the synchronous belt 14. A rotating shaft 16 is fixedly installed inside the second pulley 15. There are two rotating shafts 16, symmetrically distributed. The rotating shafts 16 are fixedly connected to the rectangular rod 18. A support frame 17 is rotatably connected to the surface of each rotating shaft 16, and the support frame 17 is fixedly connected to the base 1. The transmission assembly facilitates transmission while the reciprocating screw 4 rotates, allowing the rectangular rod 18 to rotate with the reciprocating screw 4. This ensures the measuring rope 10 is evenly wound onto the take-up reel 9. Multiple support legs 19 are fixedly installed at the bottom of the base 1. When taking up the rope, this pile foundation hole depth measuring device uses a drive assembly to rotate the reciprocating screw 4. The transmission assembly causes the rectangular rod 18 to rotate, which in turn causes the take-up reel 9 to rotate, taking in the measuring rope 10. At the same time, the reciprocating screw 4 rotates, causing the moving block 6 to move left and right along the guide rod 7, which in turn causes the moving frame 8 to move left and right, and the take-up reel 9 to move left and right. By making the take-up reel 9 move back and forth, the measuring rope 10 is evenly wound, which can effectively distribute the force on the take-up reel 9 during the working process, reduce component wear, reduce equipment maintenance and replacement costs, and improve the durability and stability of the equipment. Moreover, the evenly wound measuring rope 10 is smoother during the unwinding and take-up process, without problems such as jamming or tangling, which greatly saves measurement time.

[0022] Specifically, a guide tube 12 is fixedly installed inside the base 1, and the measuring rope 10 is slidably connected to the guide tube 12. The guide tube 12 guides the measuring rope 10 during the release and reeling, thereby assisting the measuring rope 10 in the release and reeling, so that the measuring rope 10 can be more stably wound on the reel 9.

[0023] Specifically, a rectangular groove is provided through the right side of the take-up reel 9, and the rectangular rod 18 is slidably connected to the rectangular groove, so that when the rectangular rod 18 rotates and drives the take-up reel 9 to rotate, it will not affect the left and right movement of the take-up reel 9, thereby realizing the synchronous rotation and movement of the take-up reel 9.

[0024] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0025] In use: The device is placed around the pile hole using the support leg 19. The drive motor 3 rotates the reciprocating screw 4, causing the moving block 6 to move left and right along the guide rod 7, which in turn causes the moving frame 8 to move left and right, and the take-up reel 9 to move left and right. Simultaneously, the rotation of the reciprocating screw 4 causes the first pulley 13 to rotate, which in turn causes the synchronous belt 14 to drive the second pulley 15 to rotate, causing the rotating shaft 16 to rotate, which in turn causes the rectangular rod 18 to rotate. Since the rectangular rod 18 is slidably connected to the take-up reel 9, the take-up reel 9 rotates, unwinding the measuring rope 10. Due to the gravity of the gravity block 11, the measuring rope 10 moves downward along the guide tube 12. When the gravity block 11 is parallel to the pile hole opening, the data of the measuring rope 10 is recorded. Subsequently... Continue laying out the line until the gravity block 11 moves to the bottom of the pile hole. Record the data of the measuring rope 10 at this time. The depth of the pile hole can be obtained by subtracting the two data. When it is time to take the line back, the reciprocating screw 4 is rotated by the drive motor 3, which causes the moving block 6 to move left and right along the guide rod 7, which causes the moving frame 8 to move left and right, and the take-up wheel 9 to move left and right. At the same time, the rotation of the reciprocating screw 4 causes the first pulley 13 to rotate, which causes the synchronous belt 14 to drive the second pulley 15 to rotate, which causes the rotating shaft 16 to rotate, which causes the rectangular rod 18 to rotate. Since the rectangular rod 18 is slidably connected to the take-up wheel 9, the take-up wheel 9 rotates and winds up the measuring rope 10, so that the measuring rope 10 can be evenly wound on the take-up wheel 9.
