Description

Technical Field

[0001] The utility model relates to the technical field of monitoring devices, and particularly relates to a tower crane foundation settlement monitoring device. Background Art

[0002] When the tower crane is in the working state of independent installation height, it is a relatively dangerous working condition and is easily affected by uneven settlement of the foundation, which may lead to safety accidents. The main function of the tower crane foundation settlement monitoring device is to monitor the settlement of the tower crane foundation to ensure the safety performance of tower crane construction.

[0003] Chinese Patent with the publication number of CN217840120U discloses a tower crane foundation uneven settlement monitor, which includes four groups of instrument pipes. The four groups of instrument pipes are distributed in a square at the four corners of the base platform, and a central column is arranged at the center position of the base platform.

[0004] Although the above patent is connected by a transparent plastic hose during use to ensure that the water level changes freely according to the foundation settlement situation, and the settlement amount of the tower crane base platform can be observed at any time, so that the settlement of the tower crane base platform is within a controllable range, effectively preventing the tower crane from tipping over and improving the safety performance of tower crane construction. However, since the scale lines are set on the outer side of the instrument pipe, and the PVC pipe sleeve needs to be disassembled and assembled on the instrument pipe during multiple uses of the settlement monitoring device, the scale lines on the outer side of the instrument pipe will be worn after multiple disassembly and assembly of the PVC pipe sleeve, resulting in the staff being unable to quickly and clearly view the position of the filling solution in the instrument pipe, reducing the speed of the staff monitoring and calculating the foundation settlement value. Therefore, a new type of tower crane foundation settlement monitoring device is urgently needed to solve these problems. Summary of the Invention

[0021] (III) Beneficial effects

[0022] The utility model has the following beneficial effects compared with the prior art:

[0023] To solve the problem that in the prior art, during the use of the existing tower crane foundation settlement monitoring device, since the scale line is set on the outer side of the instrument tube, and the PVC pipe sleeve needs to be disassembled and assembled on the instrument tube during multiple uses, the scale line on the outer side of the instrument tube will be worn by the multiple disassembly and assembly of the PVC pipe sleeve, resulting in the staff being unable to quickly and clearly view the position of the filling solution in the instrument tube, and reducing the speed of the staff to monitor and calculate the foundation settlement value. The utility model symmetrically arranges limiting blocks on the side wall of the instrument tube. When the pipe sleeve is installed on the instrument tube, the limiting grooves opened in the casing can be aligned with the limiting blocks on the outer wall of the instrument tube. The cooperation between the limiting blocks and the limiting grooves enables the staff to directly sleeve the casing on the instrument tube, avoiding friction between the inner wall of the casing and the instrument tube, resulting in wear of the scale line, and preventing the staff from being unable to clearly view the position of the filling solution in the instrument tube due to wear of the scale line, thereby avoiding reducing the speed of the staff to monitor and calculate the foundation settlement value.

Making the pipe column can fix the compression sleeve 3 more firmly, and the compression sleeve 3 can more conveniently compress the connecting pipe 5 to prevent the connecting pipe 5 from moving randomly. Four groups of instrument pipes 4 are installed at the four corners of the top of the base 1. A connecting pipe 5 is connected between each group of instrument pipes 4 and the central pipe column 2. A scale line 6 is arranged on one side of the outer wall of the instrument pipe 4, and limit blocks 7 are symmetrically fixed on the other two sides of the outer wall of the instrument pipe 4. A sleeve 8 is sleeved outside the instrument pipe 4, and limit grooves 9 are symmetrically opened on the inner wall of the sleeve 8. The joint of the instrument pipe 4 can fix the limit block 7 more firmly. The cooperation of the limit block 7 and the limit groove 9 can directly sleeve the sleeve 8 on the instrument pipe 4 to prevent the inner wall of the sleeve 8 from wearing the scale line 6. The bottom end of the sleeve 8 is fixedly provided with an installation sleeve plate 10, and installation holes 11 are opened on the installation sleeve plate 10. The sleeve 8 can fix the installation sleeve plate 10 more firmly, and the installation holes 11 can more conveniently enable the staff to firmly fix the installation sleeve plate 10 on the base 1. A reinforcing plate 12 is connected between the installation sleeve plate 10 and the sleeve 8. Piston pads 13 are arranged on the upper parts of the sleeve 8 and the instrument pipe 4.

[0031] As Figures 1 - 3As shown, in this embodiment, the central pipe column 2 is bolted to the compression sleeve 3. The compression sleeve 3 is clamped to the connecting pipe 5. The compression sleeve 3 is made of PVC material. Both the instrument pipe 4 and the central pipe column 2 are threadedly connected to the connecting pipe 5.

The instrument pipe 4 can ensure that the water level changes freely according to the foundation settlement by being connected to the connecting pipe 5, facilitating the observation of the settlement amount of the tower crane foundation at any time. The scale line 6 is formed on the outer wall of the instrument pipe 4.
