[0024] like Figure 1-4 As shown, a first hole 11 is opened through the bottom of the frame 1 near the middle, and a second hole 21 is opened through the top of the standing board 2 near the middle. The first hole 11 and the second hole 21 facilitate construction work on the pile holes.

[0025] like Figure 1-4 As shown, a third hole 31 is provided through the top of the support plate 3 near the middle, and the first hole 11, the second hole 21 and the third hole 31 are concentrically arranged. The third hole 31 cooperates with the protective plate 33 to play a protective role. At the same time, the third hole 31 facilitates construction operations.

[0026] like Figure 1-4 As shown, through holes 22 are symmetrically opened at the top and left and right sides of the standing board 2, and the through holes 22 are slidably set on the outer surface of the column 12. The cooperation between the through holes 22 and the column 12 guides and limits the standing board 2 to prevent the standing board 2 from tilting.

[0027] like Figure 1-4 As shown, a limit block 23 is symmetrically fixedly installed on the top of the standing board 2, and the right surface of the limit block 23 cooperates with the left surface of the second clamping block 36. Through the limit block 23, the protective plate 33 is limited in the closed state to prevent the protective plate 33 from moving over the travel.

[0028] like Figure 1-4 As shown, a U-shaped limiting rod 32 is symmetrically fixedly installed on the top of the support plate 3, and the moving rod 35 is slidably set at a position between the support plate 3 and the U-shaped limiting rod 32.

A handle 34 is fixedly installed on the top of the protective plate 33. The handle 34 is provided to facilitate pulling open the protective plate 33.

[0030] The method of use and working principle of the device: when in use, the device is installed at the position of the pile foundation hole, so that the first hole 11 is aligned with the pile foundation hole. When the person is working, he stands on the standing board 2. At this time, under the action of the person's weight, the standing board 2 will apply a downward force to the first spring 13, so that the standing board 2 sinks inside the frame 1. After that, by holding the handle 34, the protective plate 33 is pulled to the right, so that the moving rod 35 and the second block 36 move to the right synchronously. When the inclined surface of the second block 36 contacts the inclined surface of the first block 26, the first block 26 is squeezed upward until the vertical surface of the second block 36 is aligned with the vertical surface of the first block 26. Under the action of the contraction force of the second spring 25, the first block 26 is clamped in the second block 36. When the personnel leaves the standing board 2, the first spring 13 pushes the standing board 2 to move upward to reset. At the same time, the first clamping block 26 also moves upward, thereby releasing the engagement state between the first clamping block 26 and the second clamping block 36. Under the action of the contraction force of the third spring 37, the moving rod 35 is pulled to move to the left, so that the protective plate 33 moves to the left synchronously, and then the protective plate 33 covers the third opening 31, effectively avoiding the safety hazard caused by personnel forgetting to close the protective plate 33.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
