Technical Field

[0001] This invention relates to the field of foundation pit monitoring technology, specifically to a deep foundation pit excavation slope monitoring and adjustment device. Background Technology

[0002] When constructing a deep foundation pit, it is necessary to excavate to a considerable depth below ground level. To prevent the side of the soil from collapsing, the sides of the foundation pit will be excavated at a certain angle according to the process requirements. When measuring the slope of the foundation pit, RTK measuring instruments and total stations are mainly used. For the RTK measuring method, in order to facilitate the use of subsequent measurements, a tripod will be used to set up a transmission base station for the RTK measuring instrument in a fixed position, and then another RTK measuring instrument will be used for data connection and cooperation.

[0003] When setting up a base station, existing RTK measuring instruments require installation by adjusting the base, and then the level of the measuring instrument is adjusted by adjusting the legs of the base and tripod. When the ground environment is poor, the extension length of each leg needs to be adjusted repeatedly, which is cumbersome and inconvenient and affects the efficiency of base station construction.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] Please see the appendix Figure 1-9 This application provides the following three preferred embodiments.

[0033] Example 1

[0034] A deep foundation pit excavation slope monitoring and adjustment device includes a base plate 1 with three symmetrically arranged leg connection slots 2 at its lower end. A ball sleeve 3 is located at the center of the base plate 1, and a rotating cavity 4 is formed within the ball sleeve 3. A mounting base 5 is movably inserted into the rotating cavity 4 via an adaptive component. The adaptive component includes an adaptive ball head 6 and a counterweight ball 19. The adaptive ball head 6 is movably inserted into the rotating cavity 4. Several ball grooves are symmetrically arranged on both the upper and lower sides of the rotating cavity 4. Sliding balls 8 are movably inserted into each of these ball grooves, with one side of each sliding ball 8 movably passing through a ball groove and contacting the outer periphery of the adaptive ball head 6. A spacer block 7 connects the mounting base 5 and the adaptive ball head 6. An oil delivery groove is located at the center of the mounting base 5. 25. A diversion groove is vertically opened in the center of the oil delivery groove 25. Several oil drip grooves 26 are opened through the spacer block 7 in the diversion groove, and the oil drip grooves 26 are respectively set to the adaptive ball head 6. The mounting base 5 and the adaptive ball head 6 are both lightweight metal structures, and the adaptive ball head 6 is hollow. The mounting plate 1 is connected to the adjustable legs through three support leg connecting grooves 2. When setting up the base station monitoring of the RTK measuring instrument, a suitable position is selected and roughly fixed through the adjustable legs. Then, under the gravity of the counterweight ball 19, the adaptive ball head 6 performs adaptive movement in the rotating cavity 4 of the ball sleeve 3 to maintain the vertical state of the suspension rod 18, thereby keeping the mounting base 5 in a horizontal position.

[0035] During the activity, several sliding balls 8 can provide sliding support, and then, in conjunction with the oil delivery groove 25 and the oil dripping groove 26, they can continuously drip oil to lubricate the contact position between the adaptive ball head 6 and the rotating cavity 4, thereby improving the lubrication convenience of the adaptive ball head 6 and simplifying the operation.

[0036] Example 2

[0037] Based on Embodiment 1, the self-adaptive, level mounting base 5 is fixed. The fixing assembly includes a control ring 10 and several push rods 12. The push rods 12 are horizontally inserted into the mounting plate 1. Each push rod 12 has a clamping block 14 on one side, and one side of the clamping block 14 is inserted into the rotating cavity 4 and contacts the outer periphery of the self-adaptive ball head 6. The upper end of the mounting plate 1 has an annular groove 9, and the control ring 10 is rotatably mounted in the annular groove 9. The upper end of the control ring 10 is horizontally mounted with a toggle plate 17, and the outer periphery of the toggle plate 17 has a toggle notch. Several horizontal sliding grooves 11 are symmetrically arranged horizontally on the side of the mounting plate 1 near the control ring 10. The push rods 12 are horizontally movable in the several horizontal sliding grooves 11, and both the horizontal sliding grooves 11 and the push rods 12 are square structures. The horizontal sliding grooves 11 are connected to the rotating cavity 4. There is a storage groove 13. The clamping block 14 on one side of the push rod 12 is placed in the storage groove 13. The side of the clamping block 14 near the adaptive ball head 6 has a spherical arc structure, and the side of the clamping block 14 that abuts against the adaptive ball head 6 is provided with anti-slip texture. The lower end of the annular groove 9 is connected to the upper end of several horizontal sliding grooves 11. The lower end of the control ring 10 is provided with a worm-shaped thread 15. Several push screw grooves 16 are opened on the upper end of several push rods 12. The worm-shaped thread 15 at the lower end of the control ring 10 is respectively inserted into the upper push screw grooves 16 of several push rods 12. When the mounting base 5 is kept horizontal, the control ring 10 and the actuating disk 17 above the mounting base plate 1 are rotated. At this time, the control ring 10 pushes several push rods 12 horizontally through the worm-shaped thread 15, and then several clamping blocks 14 clamp and fix the outer peripheral surface of the adaptive ball head 6 to maintain the connection stability of the adaptive ball head 6.

[0038] The adaptive ball head 6 and the clamping block 14 are both provided with anti-slip texture on the side that comes into contact with each other. When the two come into contact, the lubrication effect of the lubricating oil can be overcome, and the stability of the adaptive ball head 6 and the mounting base 5 can be maintained.

[0039] Example 3

[0040] Based on Embodiment 2, a portable measurement is performed on the height of the counterweight ball 19 off the ground after adaptive alignment. The measuring component is located inside the counterweight ball 19 and includes a measuring tape 24. Both the upper and lower ends of the ball sleeve 3 are open structures. A suspension rod 18 is vertically provided at the center of the lower end of the adaptive ball head 6. The center of the upper end of the counterweight ball 19 is connected to the lower end of the suspension rod 18. An installation groove 20 is provided at the lower end of the counterweight ball 19. A connecting shaft 21 is horizontally provided in the installation groove 20. A measuring tape 24 is wound on the connecting shaft 21 by a spring. A guide plate 22 is horizontally provided at the lower end of the installation groove 20. A guide groove 23 is provided at the center of the lower end of the guide plate 22, and one side of the measuring tape 24 is vertically movable through the guide groove 23.

[0041] When the mounting base 5 is horizontal, the counterweight ball 19 remains vertical. After the mounting base 5 is fixedly connected, the height can be directly read by inserting a measuring tape 24 through the lower end of the guide groove 23 and contacting the ground. Since the counterweight ball 19 and the mounting base 5 are fixedly connected, their size is constant. The height of the entire bracket above the ground can be obtained by adding the two sizes together, which is convenient for the base station construction and data collection of the RTK measuring instrument.

[0042] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
