[0026] like Figure 1 As shown, a bored pile depth measurement auxiliary trolley comprises: a measuring rope releasing and recovering assembly 2 and a trolley 1, wherein the measuring rope releasing and recovering assembly 2 is arranged on the trolley 1, and the bottom of the trolley 1 is a supporting plate 11, a telescopic handrail 3 is arranged on one side of the supporting plate 11, and a rope supporting roller 5 is arranged on the other side, a rope guide opening 6 is opened on the supporting plate 11, and the rope guide opening 6 is located below the rope supporting roller 5, and a wheel 12 is arranged below the supporting plate 11; the cooperation between the measuring rope releasing and recovering assembly and the trolley makes it convenient for construction workers to move the measuring rope assembly to the bored pile casing through the trolley, which can effectively save manpower and improve construction efficiency; and the trolley is provided with a telescopic handrail, which is convenient for construction workers to adjust the handrail height to adapt to operators of different heights.

[0027] The measuring rope releasing and recovering assembly 2 further comprises: an axle seat 21, a roller 22, a baffle 23, a rotating handle 24 and a measuring rope 4. The axle seat 21 is fixedly connected to the supporting plate 11. A baffle 23 is fixedly connected to each side of the axle seat 21. A roller 22 is rotatably connected between the two baffles 23. A measuring rope 4 is wound around the roller 22. A scale is provided on the measuring rope 4 to facilitate construction personnel to read the depth of the bored pile through the measuring rope 4. A rotating handle 24 is fixedly connected to one end of the roller 22. The rotating handle 24 is used to drive the roller 22 to rotate, thereby realizing the release and recovery of the measuring rope 4. The measuring rope 4 is overlapped on the rope supporting roller 5. One end of the measuring rope 4 is connected to a lifting ring 8 after passing through the rope guide opening 6. A measuring rod 7 is fixedly connected to the lower part of the lifting ring 8. The measuring rod 7 is used to provide a counterweight for the measuring rope 4 to ensure the verticality of the measuring rope 4.

[0028] like Figure 2-3 As shown, the telescopic handrail 3 further includes: two handrail fixing rods 33, the handrail fixing rods 33 are fixedly connected to the supporting plate 11, the handrail fixing rods 33 are movably connected with the handrail telescopic rods 34, the handrail telescopic rods 34 are slidably provided with telescopic buttons 32, the telescopic buttons 32 and the handrail telescopic rods 34 are matched through telescopic springs 321, a plurality of telescopic fixing holes 331 are opened on the handrail fixing rods 33, the telescopic fixing holes 331 are used to match with the telescopic buttons 32, and the construction personnel release the matching between the handrail telescopic rods 34 and the handrail fixing rods 33 by pressing the telescopic knobs 32, thereby adjusting the height of the handrail 35; the upper end of the handrail telescopic rod 34 is connected to the handrail 35 through the handrail fixing bolts 31, and the construction personnel can adjust the angle of the handrail 35 by adjusting the handrail fixing bolts 31.

[0029] like Figure 1 As shown, the measuring rod 7 further includes: a long steel bar 71, on the circumferential side wall of the long steel bar 71 are four short steel bars 72 evenly and fixedly connected at the same height, the bottom end of the long steel bar 71 is lower than the bottom end of the short steel bars 72, so as to prevent the sediment at the bottom of the bored pile hole from affecting the measurement accuracy.

[0030] like Figure 4-5As shown, a slide groove 25 is provided on the rotating handle 24, and a slider 28 is slidably connected in the slide groove 25. A connecting rod 27 is threadedly connected to the slider 28. The end of the connecting rod 27 away from the slider 28 is fixedly connected to the handle 26. The part of the connecting rod 27 that cooperates with the slider 28 is a threaded rod 271. The threaded rod 271 passes through one end of the slider 28 and is fixedly connected to a limiting block 272. The diameter of the limiting block 272 is larger than the diameter of the threaded rod 271. A receiving groove for accommodating the limiting block 272 is provided on the side wall of the slider 28, and the height of the receiving groove is larger than the height of the limiting block 272. The construction personnel can drive the connecting rod 27 to rotate by rotating the handle 26. After the connecting rod 27 rotates, the threaded rod 271 moves up and down on the slider 28, thereby adjusting the cooperation between the limit block 272 and the slide groove 25. When the position of the handle 26 needs to be moved, the handle 26 is rotated to make the limit block 272 move upward, and the slider 28 can move freely in the slide groove 25. When the handle 26 needs to be fixed, the handle 26 is rotated to make the limit block 272 move downward and abut against the slide groove 25, thereby limiting the movement of the slider 28. As the measuring rope 4 is continuously released, if the position of the handle 26 does not change, the force required to recover the measuring rope may increase, and the construction personnel cannot rotate the rotating handle. By changing the position of the handle 26 on the rotating handle 24, the force situation can be changed, and the force required to recover the measuring rope 4 can be reduced by increasing the moving distance, which is more adaptable.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
