[0032] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0033] Example 1 See also Figures 1 to 12 The present invention provides a pile foundation safety protection cover capable of monitoring the verticality of a casing, comprising a bottom plate truss 1 for fixing on a steel casing and a protection truss 2 slidably connected to the bottom plate truss 1, wherein a plurality of level bubbles are arranged on the bottom plate truss 1; The level bubble directly displays the horizontal state of the bottom plate truss 1. Construction personnel can intuitively judge whether the casing is vertical without relying on complex instruments. During the installation or deviation correction of the casing, the level bubble provides real-time feedback, which facilitates the rapid adjustment of the verticality of the casing. Workers can use the level to monitor verticality without training, reducing labor costs; Moreover, the level bubble is inexpensive and easy to install, which can significantly reduce the cost of construction monitoring; Furthermore, the level bubble can be used in conjunction with electronic monitoring systems, such as inclination sensors, laser levels, etc., to form redundant monitoring and improve data reliability; The bottom plate truss 1 includes a rectangular frame 3, two cross beams 4 are fixedly arranged in the middle of the frame 3, and a passage for the circulation of personnel and materials is formed between two adjacent cross beams 4. When the protective truss 2 moves to the top of the passage, the protective truss 2 closes the passage. A track 5 is fixedly arranged at each of the four corners of the bottom plate truss 1 , and the extension lines of the projections of the four tracks 5 on the horizontal plane intersect at the center point of the frame 3 . A casing locker 6 is slidably arranged on each track 5 .

[0034] Place the bottom plate truss 1 on the upper end of the casing, adjust the position of the casing locker 6 respectively, make the casing locker 6 contact with the casing, and fix the bottom plate truss 1 on the casing through the casing locker 6. When construction personnel or materials need to pass through the passage, slide the protective truss 2 to the non-passage area to keep the passage open. When the passage needs to be closed, slide the protective truss 2 to the top of the passage to form a safety barrier. The protective truss 2 can quickly close the passage to prevent people or materials from falling, significantly improving the safety during the construction process; Both the track 5 truss and the protective truss 2 are standardized modules, which are easy to install and disassemble, and are suitable for turnover construction between casings with multiple pile positions and different diameters; Furthermore, a protective net can be set in the non-channel area of ​​the base plate truss 1 and the protective truss 2 to further provide safety protection for the non-channel area. Compared with the fully enclosed steel plate, the protective net is lightweight and will not significantly increase the load on the base plate truss 1, and is suitable for construction scenarios with frequent movement.

[0035] Two angle steels 7 are arranged opposite to each other on the frame 3, and the projection of the angle steels 7 on the horizontal plane is perpendicular to the crossbeam 4. A slide rail 8 is fixedly arranged on each angle steel 7, and the length of the slide rail 8 is two-thirds of the length of the frame 3. The length of the slide rail 8 can ensure that the protective truss 2 can slide to the top of the channel. Furthermore, a limit platform is respectively arranged at both ends of the slide rail 8, and the limit platform can ensure that the protective truss 2 always slides on the slide rail 8. A number of sliders are fixedly arranged at both ends of the protective truss 2, and the protective truss 2 is slidably connected to the bottom plate truss 1 through the slide rail 8 sliders.

[0036] The casing locker 6 comprises an "H"-shaped slide 10 slidably arranged on the track 5, and the slide 10 is composed of two vertical side plates 11 and a web 12 fixed in the middle of the two side plates 11; the two side plates 11 are respectively located on both sides of the track 5, the web 12 is located above the track 5, and the lower ends of the two side plates 11 are flush with the lower surface of the track 5; A side panel 13 is fixedly disposed on each of the two side panels 11. The lower ends of the two side panels 13 are fixedly connected by a fixing plate 14. The fixing plate 14 is located below the track 5. A positioning rod 15 is fixedly disposed on each side panel 13, and a boss 16 is fixedly disposed on one end of the positioning rod 15 away from the side panel 13; A clamping arm 17 is disposed on one side of each side plate 11, and a sliding groove 18 is provided on the clamping arm 17, and the positioning rod 15 slides in the sliding groove 18; The slide 10 is also rotatably provided with a control unit 19 for controlling the movement of the clamping arm 17 .

[0037] The bottom plate truss 1 is placed on the upper end of the casing, and the positions of the casing lockers 6 are adjusted respectively so that the fixing plate 14 of the casing locker 6 is in contact with the outer wall of the casing. The user operates the control unit 19 to move the clamping arm 17 downward so that the clamping arm 17 is in contact with the inner wall of the casing. Through the combined action of the clamping arm 17 and the fixing plate 14, the casing locker 6 can firmly clamp the casing, thereby achieving vibration resistance stability and convenient operation of the casing locker 6.

[0038] The control unit 19 includes two swing arms 20 rotatably disposed on the side plate 11 , and the movable ends of the two swing arms 20 are fixedly connected by a handle 21 ; A control rod 22 is fixedly disposed at the rotating end of each swing arm 20, a notch 23 is provided on the clamp arm 17, and the movable end of the control rod 22 is inserted into the notch 23; A clamping plate 24 is disposed at one end of the control rod 22 close to the swing arm 20 . The outer wall of the clamping plate 24 is arc-shaped, and the axis of the clamping plate 24 is staggered with the axis of the swing arm 20 .

[0039] When the casing locker 6 is in use, the user holds the handle 21 and rotates the handle 21 to one side of the clamp arm 17. When the handle 21 rotates, the clamp arm 17 is driven to move downward through the control rod 22. When the clamping plate 24 is attached to the clamp arm 17 as the swing arm 20 rotates, due to the eccentric design of the axis of the clamping plate 24 and the axis of the swing arm 20, the clamp arm 17 is tilted under the action of the boss 16, generating a lever effect, pushing the clamp arm 17 to move toward the casing. At the same time, the contact surface of the clamping plate 24 and the clamp arm 17 forms a self-locking friction force to prevent rebound. Furthermore, a rubber pad is provided on the side of the lower end of the clamp arm 17 facing the fixing plate 14, and the rubber pad can increase the friction between the clamp arm 17 and the casing to avoid overload clamping and damage to the casing surface; When the casing locker 6 needs to be removed, the handle 21 is rotated in the opposite direction, the control rod 22 drives the clamping arm 17 to move upward, the clamping plate 24 is separated from the clamping arm 17, and the lower end of the clamping arm 17 moves to above the lower end of the track 5, so as to separate the bottom plate truss 1 from the casing.

[0040] A spring 25 is sleeved on the outer side of the positioning rod 15 , one end of the spring 25 abuts against the side panel 13 , and the other end of the spring 25 abuts against the clamping arm 17 .

[0041] The spring 25 can ensure that the clamp arm 17 is in contact with the boss 16. When the casing needs to be clamped, the spring 25 can produce a certain deformation to tilt the clamp arm 17. Under the action of the boss 16 and the clamping plate 24, a lever effect is generated to clamp and fix the casing.

[0042] Example 2 On the basis of embodiment 1, a guide groove 26 is provided on the side wall of the track 5, and a screw rod 27 is provided inside the track 5 for rotation; A nut 28 is fixedly disposed between the two side plates 11 below the web 12 . The nut 28 is fixedly connected to the two side plates 11 via a mounting bracket 29 that penetrates the guide groove 26 . The nut 28 is threadedly connected to the screw rod 27 .

[0043] The user can adjust the position of the carriage 10 on the track 5 by rotating the screw rod 27. The user can select a manual crank or a motor drive according to the construction conditions to meet the needs of different scenarios. At the same time, the screw rod 27 has high transmission efficiency, the carriage 10 moves quickly, and the adjustment time is shortened. The threaded fit between the screw rod 27 and the nut 28 has a certain self-locking property, and construction vibration or external force impact will not cause the slide 10 to shift, thereby ensuring the stability of the casing locker 6.

[0044] A driven bevel gear 31 is fixedly disposed at one end of each screw rod 27, one side of the driven bevel gear 31 is meshed with a driving bevel gear 32, and the driving bevel gear 32 is rotatably connected to the bottom truss; A pulley 33 is coaxially fixedly disposed on each driving bevel gear 32 , and the plurality of pulleys 33 are connected by a transmission belt 33 .

[0045] By rotating any active bevel gear 32, the transmission belt 33 can be driven by a manual crank or a motor to move, so that all active bevel gears 32 rotate synchronously. The transmission belt 33 is linked to multiple pulleys 33, and a single-point drive can achieve multi-point synchronous adjustment, greatly shortening the adjustment time; The active bevel gear 32 drives the driven bevel gear 31 to drive the screw rod 27 to rotate, so that all the casing lockers 6 move synchronously along the track 5 to avoid casing deflection caused by single-point adjustment.

[0046] Example 3 On the basis of Embodiment 1 or 2, two groups of truss lockers 9 are arranged on one side of the protective truss 2 close to the passage, and each group of truss lockers 9 is located at two ends of the protective truss 2 respectively.

[0047] When the passage needs to be closed, the protective truss 2 is slid to the top of the passage, and the position of the protective truss 2 is fixed by the truss lock 9 to close the passage. The truss lock 9 can effectively prevent the protective truss 2 from being displaced, greatly improving the safety of the protective truss 2 during use.

[0048] The truss locker 9 includes a mounting seat 34 fixedly mounted on the protective truss 2, a pressure rod 35 rotatably mounted on the mounting seat 34, and a pressure head 36 is mounted on the movable end of the pressure rod 35; A handle 37 is rotatably provided on the mounting seat 34 . The middle portion of the handle 37 is rotatably connected to the mounting seat 34 . One end portion of the handle 37 close to the pressure rod 35 is rotatably connected to the pressure rod 35 via a connecting rod 38 .

[0049] The pressure rod 35 is L-shaped, the shorter end of the pressure rod 35 is rotatably connected to the mounting seat 34, the longer end is provided with a pressure head 36, and the connecting rod 38 is rotatably connected to the corner of the pressure rod 35; The user turns the handle 37, and the handle 37 pushes the pressure rod 35 to rotate around the mounting seat 34 through the connecting rod 38, and the pressure head 36 rotates toward the beam 4 and makes the pressure head 36 abut against the beam 4. At this time, the protective truss 2 can avoid sliding to the non-channel area side under the action of the limit platform and the truss lock 9, preventing the protective truss 2 from being displaced, thereby greatly improving the safety of the protective truss 2 during use.

[0050] A column is arranged on one side of the handle 37, a limit plate 39 is arranged on the column, a clamping plate 41 is arranged at one end of the limit plate 39, a rubber sleeve is arranged at the other end, a compression spring 40 is sleeved on the outer side of the column, one end of the compression spring 40 is fixedly connected to the column, and the other end is fixedly connected to the limit plate 39; The mounting seat 34 is provided with slots 42 , and the clamping plate 41 of the limiting plate 39 is clamped with one of the slots 42 .

[0051] The card plate 41 can further limit the position of the handle 37. When the card plate 41 is inserted into the card slot, it forms a rigid fixation to prevent the handle 37 from accidentally moving. At the same time, when the protective truss 2 needs to be moved, the card plate 41 is inserted into another slot 42. At this time, the pressure rod 35 can be rotated upward and maintain this state. During the movement of the protective truss 2, the pressure rod 35 will not contact the beam 4 and will not hinder the movement of the protective truss 2. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
