[0065] Its working principle is: when the transmission rod 524 rotates, the first bevel gear 65 rotates, and since the first bevel gear 65 and the second bevel gear 66 are meshed, the second bevel gear 66 rotates; since the second bevel gear 66 and the end of the rotating bracket 64 are fixed, the rotating bracket 64 is driven to rotate; since the end of the rotating bracket 64 and the second gear 63 are fixed, the second gear 63 is driven to rotate; since the second gear 63 and the first gear 62 are meshed, the first gear 62 is driven to rotate; since the first gear 62 and the supporting plate 42 are fixed, the supporting plate 42 is driven to rotate, so that the electric heating plate 44 on the surface of the supporting plate 42 comprehensively dries the measuring rope 51.

[0066] For the above example, those skilled in the art should know that the structure of the bevel gear can be adjusted. For example, the bevel gear can be replaced by a belt and pulley or a chain and sprocket structure, so that the transmission rod 524 can rotate while the rotating bracket 64 can rotate.

[0067] The utility model provides a pile foundation penetration measurement device, and its working principle is:

During the recovery of the measuring rope 51, the turntable 222 is rotated, and the double-axis screw rod 221 rotates, so that the two sliders 223 move closer to the middle. Under the action of the connecting rod 224, the two chucks 21 wrap the measuring rope 51, and the inner diameter of the chuck 21 is consistent with the outer diameter of the measuring rope 51, so that when the measuring rope 51 is recovered, the convex point 211 inside the chuck 21 The mud on the surface of the measuring rope 51 can be scraped off; then, the measuring rope 51 rises, and the nozzle 33 sprays water to clean the measuring rope 51; the measuring rope 51 continues to rise, and the first bevel gear 65 on the surface of the transmission rod 524 rotates, and the first bevel gear 65 meshes with the second bevel gear 66 at one end of the rotating bracket 64, so that the rotating bracket 64 rotates, and the second gear 63 at the other end of the rotating bracket 64 meshes with the first gear 62 on the lower surface of the bearing plate 42, so that the bearing plate 42 can rotate, so that the electric heating plate 44 on the surface of the bearing plate 42 can dry the measuring rope 51. The measuring rope 51 after drying is retracted and wound on the rope roller 522, and the measuring rope 51 recovery operation is completed.

[0069] The utility model provides a pile foundation penetration measurement device with the following advantages:
