Description

Technical Field

[0001] The utility model relates to the technical field of pile driver construction, in particular to a pile driver construction depth detection device. Background Art

[0002] Bored cast-in-place piles refer to piles made by forming pile holes in the foundation soil at the construction site through mechanical drilling, steel pipe squeezing or manual excavation, placing a steel cage inside and pouring concrete.

[0003] After the construction workers complete the bored pile drilling operation, they need to use measuring tools to measure and verify the hole depth.

[0004] For example, Chinese patent publication number CN212658186U discloses a pile hole depth measuring device, which includes a bracket, a stepped shaft horizontally rotatably inserted into the bracket, and a rotating drum fixedly mounted on the circumference of the stepped shaft, a measuring rope is wound around the circumference of the rotating drum, a detection probe is fixedly mounted on the free end of the measuring rope, a toothed ring coaxial with the stepped shaft is fixedly mounted on the side wall of the bracket, and a tooth groove of the toothed ring is provided on the inner wall of the toothed ring. This application has the effect of limiting the maximum lowering speed of the measuring rope.

[0005] When the measuring device puts the measuring rope into the pile hole for depth measurement, the mud in the pile hole is easy to adhere to the measuring rope. Then, after the pile hole depth measurement is completed, when the measuring rope is reeled in, the mud adheres to the measuring rope, which not only causes mud stains to remain on the measuring rope, but also affects the subsequent readings of the measuring rope, resulting in inaccurate pile hole depth value when used next time.

DETAILED DESCRIPTION

[0030] See also Figures 1 to 4As shown, the utility model provides a pile driver construction depth detection device, comprising a frame 1, a detection mechanism and a flushing mechanism. The frame 1 comprises a base plate 2, a through hole 3 is provided in the middle of the base plate 2, and specifically, the frame 1 further comprises two mounting frames fixed on both sides of the base plate 2. The detection mechanism includes a storage box 4, a roller 6, a measuring tape 7, a counterweight 9 and a contact sensor 10. The storage box 4 is fixed between the two mounting frames. An opening 8 is provided at the lower end of the storage box 4. The roller 6 is rotatably arranged in the storage box 4. The measuring tape 7 is wound around the outside of the roller 6, and the lower end of the measuring tape 7 passes through the opening 8 and the through port 3 and is arranged outside the substrate 2. The counterweight 9 is fixed at the lower end of the measuring tape 7. The contact sensor 10 is installed at the lower end of the counterweight 9; the flushing mechanism includes a water tank 12, a water pump 13, a water pipe 14 and a flushing pipe 15. The water tank 12 is fixed on the substrate 2, the water pump 13 is fixed on a side wall of the water tank 12, the two ends of the water pipe 14 are respectively connected to the water pump 13 and the flushing pipe 15, the flushing pipe 15 is fixed on the lower side of the substrate 2, and the flushing port of the flushing pipe 15 is aligned with the measuring tape 7.

[0031] When the depth of the pile driver deep hole needs to be detected, the device is placed directly above the deep hole, and the reel 6 is rotated to unwind the tape measure 7. At this time, the counterweight 9 pulls the tape measure 7 downward in the deep hole. When the contact sensor 10 contacts the bottom of the hole, a signal is given, and the reel 6 is stopped. Then, the depth value of the deep hole can be obtained by observing the scale on the tape measure 7. After the detection is completed, the water pump 13 is started, and the tape measure 7 is flushed through the flushing port, and then the tape measure 7 is reeled by rotating the reel 6. During the upward movement of the tape measure 7, the flushing pipe 15 flushes the tape measure 7 and then continues to move upward to the storage box 4, so that it can be used next time.

[0032] Furthermore, the flushing pipe 15 is arranged in a U-shaped structure, the flushing pipe 15 is arranged around the outside of the through opening 3, and a plurality of flushing ports are arranged on two opposite side walls of the flushing pipe 15.

[0033] By setting the flushing pipe 15 as a U-shaped structure, it is convenient to place the measuring tape 7 in the middle of the flushing pipe 15, and both sides of the measuring tape 7 can be flushed at the same time, thereby improving the flushing efficiency.

[0034] Preferably, each of the flushing ports is provided with a spray head, which can increase the water pressure and spray water onto the surface of the tape measure 7 more accurately and with greater force, thereby further washing away the mud on the surface of the tape measure 7.

[0035] Furthermore, a scraping mechanism is also provided on the base plate 2, and the scraping mechanism includes a fixed strip housing 16, a bidirectional screw rod 18, two nut blocks 19, two scrapers 20 and a hand wheel 17. The fixed strip housing 16 is fixed on the upper side of the base plate 2 and is located on one side of the through opening 3; the bidirectional screw rod 18 is rotatably arranged in the fixed strip housing 16; the two nut blocks 19 are respectively threadedly connected to the two ends of the bidirectional screw rod 18; one end of the two scrapers 20 is respectively fixed to the two nut blocks 19, and the other end extends to the opposite sides of the through opening 3; the hand wheel 17 is arranged at one end of the fixed strip housing 16 and is fixedly connected to one end of the bidirectional screw rod 18.

[0036] After the depth measurement is completed, when the measuring tape 7 is rolled up, the hand wheel 17 is turned to drive the bidirectional screw 18 to rotate. At this time, the two nut blocks 19 are forced to move toward each other, driving the two scrapers 20 to approach each other until they are in contact with the two sides of the measuring tape 7. When the measuring tape 7 is rolled up, the mud and water on it can be automatically scraped off, which is convenient for cleaning. The measuring tape 7 on the lower side of the scraper 20 is first washed through the washing pipe 15, and the washed measuring tape 7 is moved up and then scraped off by the scraper 20, so that all water stains on the measuring tape 7 can be scraped off.

[0037] Specifically, the inner wall of the fixed bar housing 16 is slidably connected to the side wall of the nut block 19 , so as to limit the axial rotation of the nut block 19 .

[0038] Furthermore, two symmetrically arranged telescopic rods 21 are fixedly connected to the two side walls on the opposite sides of the base plate 2, and the ends of the two telescopic rods 21 away from the base plate 2 are fixedly connected to the supporting floor 22, which is convenient for adjusting the length so as to adapt to the placement of deep holes for pile driver construction of different calibers.

[0039] Preferably, rivets are provided on the lower end surface of the support floor 22 , and the rivets can be inserted into the soil next to the deep hole to maintain the stability of the frame 1 .

[0040] In one embodiment, a motor 5 is fixed to one side of the storage box 4, and the motor 5 is connected to the roller 6 to drive the roller 6 to rotate. In other embodiments, a hand crank can also be provided to manually drive the roller 6 to rotate.

[0041] Furthermore, a control panel 11 is fixed to the side wall of the storage box 4, and the control panel 11 is electrically connected to the motor 5 and the contact sensor 10.
