Description

Technical Field

[0001] The utility model belongs to the technical field of pile foundation hole depth measurement, and specifically refers to a pile foundation hole depth measurement device for pile foundation construction. Background Technique

[0002] Pile foundation is an ancient foundation type. The pile construction technology has experienced a development process of thousands of years. Whether it is the pile foundation materials and pile types, or the pile construction machinery and construction methods, they have all had great developments, and a modern foundation engineering system has been formed. In some cases, the use of pile foundation can greatly reduce the workload and material consumption at the construction site. In the project of pile foundation construction, for buildings and structures with relatively high bearing capacity requirements, the foundation form is usually bored cast-in-place pile, and the pile foundation depth of the cast-in-place pile is an important inspection index to determine whether the hole is qualified. Only by ensuring the quality of the hole can the foundation of the building be firm and no collapse accident occur.

[0003] Patent CN211740081U discloses a pile foundation depth measurement device. When the weight is lowered in this patent, the connecting rod cannot be telescopically adjusted, and the weight is prone to collide with the inner wall of the foundation pile, causing losses. Moreover, when not in use, it is not convenient to retract the connecting rod, occupying a large space. Content of the Utility Model

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. The following will further describe the present utility model in detail in conjunction with the accompanying drawings.

[0019] As Figure 1-2 shown, a device for measuring the depth of a pile foundation hole for pile foundation construction proposed by the present utility model includes a base 1, a support plate 2, a winding assembly 3 and an extending assembly 4. The support plate 2 is arranged on the base 1, the winding assembly 3 is arranged on the support plate 2, and the extending assembly 4 is arranged on the support plate 2. The extending assembly 4 includes a sliding cylinder 5, a sliding rod 6 and a connecting rod 7. One end of the sliding cylinder 5 is rotatably arranged on the inner side wall of the support plate 2, the sliding rod 6 is slidably arranged on the inner side wall of the sliding cylinder 5, a fastening bolt 8 is bolted 23 to the side wall of the sliding cylinder 5, and the end of the fastening bolt 8 abuts against the side wall of the sliding rod 6. The connecting rod 7 is arranged at the end of the sliding rod 6, and a guide wheel 9 is arranged on the connecting rod 7. A locking member 10 is arranged on the side wall of the support plate 2. By loosening the fastening bolt 8, the sliding rod 6 can be slid outwards, and the guide wheel 9 on the connecting rod 7 extends outwards, so that when in use, the heavy hammer 21 can be prevented from approaching the inner side wall of the pile foundation and causing impact and loss. When not in use, the sliding rod 6 is retracted, and the locking member is opened, and the sliding cylinder 5 and the sliding rod 6 are rotated downwards and retracted below the winding assembly 3 to save space.

[0020] The locking member 10 includes a plate frame 11, a gear 12 and a bolt 13. The shaft of the gear 12 rotates through the support plate 2 and is connected to the sliding cylinder 5. The plate frame 11 is arranged on the side wall of the support plate 2. The bolt 13 slides through the plate frame 11 and is inserted into the tooth of the gear 12 and the support plate 2. By pulling out the bolt 13 from the tooth of the gear 12, the sliding cylinder 5 and the sliding rod 6 can be rotated, and by inserting the bolt 13, the angles of the sliding cylinder 5 and the sliding rod 6 can be fixed.

[0021] The winding component 3 includes a rotating shaft 14, a winding roller 15, a positioning member 16 and a driving member 17. Both ends of the rotating shaft 14 rotatably penetrate through the support plate 2 and extend outwards at both ends. The winding roller 15 is rotatably sleeved on the rotating shaft 14. The positioning member 16 is arranged between the rotating shaft 14 and the winding roller 15. The driving member 17 is arranged on the side wall of the support plate 2.

[0022] A connecting column 18 is arranged on the side wall of the sliding rod 6, and a guiding sleeve 19 is arranged on the connecting column 18.

[0023] A rope 20 is arranged on the winding roller 15. One end of the rope 20 is wound around the winding roller 15, and the other end of the rope 20 passes through the guiding sleeve 19 and the guiding wheel 9 and is freely arranged. A plumb bob 21 is arranged at the free end of the rope 20.

[0024] The positioning member 16 includes a support plate 22 and a bolt 23. A threaded hole 24 is arranged on the rotating shaft 14. The support plate 22 is arranged on the side wall of the winding roller 15. The bolt 23 is in threaded connection with the support plate 22 and the threaded hole 24. When the plumb bob 21 is lowered, the bolt 23 is removed from the threaded hole 24, then the winding roller 15 can rotate on the rotating shaft 14 and can be quickly lowered. When the bolt 23 is inserted into the threaded hole 24 again, when the driving member 17 works, the rotation can drive the winding roller 15 to wind the rope 20.

[0025] The driving member 17 includes a worm gear 25, a worm 26 and a driving motor 27. The worm gear 25 is fixedly sleeved on the rotating shaft 14. A fixing plate 28 is arranged on the side wall of the support plate 2. Both ends of the worm 26 are rotatably arranged on the fixing plate 28. The worm 26 is in mating connection with the worm gear 25. The driving motor 27 is arranged on the side wall of the fixing plate 28. The output end of the driving motor 27 rotatably penetrates through the fixing plate 28 and is connected to the worm 26. When the driving motor 27 is started, the worm 26 is driven to rotate. The worm 26 drives the worm gear 25 to rotate. The worm gear 25 drives the rotating shaft 14 to rotate. Through the worm gear 25 and the worm 26, the rotating shaft 14 can be locked after the driving motor 27 is powered off, avoiding its self-rotation and making the rope 20 loose and scattered.

[0026] During specific use, this device is placed near the pile foundation. By loosening the fastening bolt 8, the sliding rod 6 can be slid outwards, and the guiding wheel 9 on the connecting rod 7 extends outwards. Then, during use, it can be avoided that the plumb bob 21 approaches the inner side wall of the pile foundation, causing impact and loss. At this time, the plumb bob 21 is lowered, and the bolt 23 is removed from the threaded hole 24. Then, the winding roller 15 can rotate on the rotating shaft 14 due to the pulling of the plumb bob 21 and can be quickly lowered.

[0027] When not in use, the bolt 23 is inserted into the screw hole 24 again. The driving motor 27 is started to drive the worm 26 to rotate. The worm 26 drives the worm wheel 25 to rotate, and the worm wheel 25 drives the rotating shaft 14 to rotate. The winding roller 15 on the rotating shaft 14 rotates with the rotating shaft 14 under the limitation of the bolt 23. The rotating shaft 14 can be locked by the worm wheel 25 and the worm 26 after the driving motor 27 is powered off, preventing it from rotating on its own and causing the rope 20 to become loose and scattered. Then, the slide rod 6 is retracted into the slide cylinder 5, and the pin 13 is pulled out from the teeth of the gear 12. The slide cylinder 5 and the slide rod 6 can be rotated downward and retracted below the winding assembly 3 to save space.

[0028] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the creative purpose of the present invention, they shall fall within the protection scope of the present invention.
