Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a real-time monitoring device for the elevation of pre-embedded legs of a tower crane foundation. Background Art

[0002] When the tower crane foundation legs are embedded, the top elevation of the foundation embedded legs (generally four ends) must be checked and adjusted multiple times before and after the foundation reinforcement is tied, and before and after the concrete is poured, to prevent the tower crane from tilting in the later stage or unnecessary adjustment and repair of customized components due to the uneven top of the foundation section during the construction process until the foundation concrete is finally set.

[0003] At present, the method of controlling the pre-embedded legs of tower cranes generally adopts optical leveling or laser leveling to achieve the above purpose. However, in actual operation, there are still tower tilts or additional prefabricated calibration sections due to inconsistent top elevations of pre-embedded foundation legs of tower cranes. The main reason is that the displacement of the foundation section is caused by careless operation during the steel binding process or concrete pouring process of the tower crane foundation, and the elevation change of the top of the pre-embedded section cannot be monitored in real time, resulting in the failure to calibrate the top elevation of the foundation pre-embedded section in time.

[0004] In view of the above situation, it is very necessary to monitor the elevation of the top of the tower crane's embedded legs in real time during the process from the installation of the tower crane's pre-embedded legs to the final setting of the foundation concrete (especially during the steel bar binding and concrete pouring and vibration). Utility Model Content

[0005] The purpose of the utility model is to provide a device or equipment that can monitor the top elevation of the tower crane pre-embedded legs in real time during the process of supporting the pre-embedded legs to the final setting of the foundation concrete (especially during the period of steel bar tying and concrete pouring and vibration), and assist the tower crane foundation pre-embedded legs to maintain the top elevation horizontal, so as to meet the safety requirements of the tower crane. The specific technical scheme adopted is: a real-time monitoring device for the elevation of the pre-embedded legs of the tower crane foundation, including: a liquid level gauge tube and a connecting conduit, each leg is provided with a liquid level gauge tube, the liquid level gauge tubes are connected to each other through the connecting conduit, the liquid level gauge tube is filled with level liquid, and the liquid level gauge tube is provided with a scale line, the liquid level gauge tube is provided with an air hole, and at least the portion of the liquid level gauge tube corresponding to the scale line is transparent or translucent.

[0006] A further improvement is that the bottom end of each of the liquid level gauge tubes is connected to a connecting conduit, and the other ends of all of the connecting conduits are connected to a communicating vessel.

[0007] A further improvement is that the liquid level gauge tube is designed to be open at the upper end, and a cover body is provided at the top end of the liquid level gauge tube.

[0008] A further improvement is that the air hole is arranged on the cover body, and a dustproof filter layer is provided at the air hole.

[0009] A further improvement is that a splash-proof breathable membrane is provided at the air hole.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0023] In the utility model, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like 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 an indirect connection 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 utility model can be understood according to the specific circumstances.

[0024] like Figure 1 and Figure 2 As shown, the utility model provides a real-time monitoring device for the elevation of pre-embedded legs of a tower crane foundation, comprising: a liquid level gauge tube 1 and a connecting conduit 2, each tower crane leg 100 is fixedly installed with a liquid level gauge tube 1, and its installation method can be connected by super glue or bolts, etc. The liquid level gauge tubes 1 are connected to each other through the connecting conduit 2 to form a communicating vessel system, the liquid level gauge tube 1 is filled with a level liquid, and a scale line 3 is drawn, pasted or carved on the liquid level gauge tube 1, and the liquid level gauge tube 1 is provided with air holes, and at least the corresponding part of the scale line of the liquid level gauge tube 1 is transparent or translucent. After installation, the elevation difference between the level liquid surface in the liquid level gauge tube 1 and the top surface of each leg can be observed, and the horizontal changes of the pre-embedded legs of the tower crane foundation and even the tower crane foundation can be displayed in real time during the whole process from the positioning of the pre-embedded legs of the tower crane foundation to the final setting of the concrete pouring of the tower crane foundation. In order to facilitate observation of the liquid level change, the liquid level scale tube must be made of a fully transparent or translucent material, such as high molecular weight polypropylene, or a transparent or translucent observation window may be provided at the position with the scale line.

[0025] The utility model provides a real-time monitoring device for the elevation of pre-buried legs of a tower crane foundation, which can implement real-time monitoring in the entire process of supporting the pre-buried legs of the tower crane foundation and pouring foundation concrete, and can assist the legs in adjusting the horizontality of the top ends of the legs at any time before the final setting of the tower crane foundation concrete; the utility model is convenient for observation and does not rely on professional measuring instruments; the utility model can be assembled manually by workers, and the operation and maintenance are simple; the utility model is low in cost and can be used in a turnover manner, and provides a technical guarantee for ensuring the accurate pre-buried legs of the tower crane foundation, and is of great significance to the installation, detection and use of large machinery such as tower cranes.

[0026] A further improvement is that the bottom end of each of the liquid level gauge tubes 1 is connected to a connecting conduit 2, and the other ends of all the connecting conduits 2 are connected to a communicating vessel 4. The communicating vessel 4 cooperates with the connecting conduit 2 to connect all the liquid level gauge tubes to form a communicating vessel system. The connecting conduit 2 and the communicating vessel 4 can be connected by plugging or hot-melt. In this embodiment, there are four legs, so the four liquid level gauge tubes are connected to a cross communicating vessel through the connecting conduit to form a communicating vessel system.

[0027] A further improvement is that the liquid level gauge tube 1 is designed to be open at the upper end, and a cover 5 is provided at the top of the liquid level gauge tube 1. The cover 5 is covered or inserted at the top of the liquid level gauge tube 1 by interference fit or transition fit. In order to increase the sealing effect, a sealing ring can be added to the cover 5.

[0028] A further improvement is that the air hole is arranged on the cover body 5, and a dustproof filter layer is adhered or embedded on the air hole, so that external dust cannot enter the liquid level gauge tube, thereby preventing the gauge tube from being contaminated and displaying unclearly or preventing the display from being inaccurate due to stagnation of dust in the horizontal liquid.

[0029] A further improvement is that a splash-proof breathable film is adhered to the air hole, so that the internal level liquid of the liquid level gauge tube 1 is guaranteed not to splash, evaporate or spill under the premise that the air pressure inside and outside the liquid level gauge tube 1 is the same.

[0030] A further improvement is that the leveling liquid is an antifreeze liquid to improve the environmental adaptability of the device.

[0031] A further improvement is that the antifreeze liquid is a colored antifreeze liquid, which not only makes it easy to observe the liquid level change, but also makes it possible to promptly find where the device is damaged or leaking.

[0032] A further improvement is that the connecting conduit 2 is made of thermoplastic elastic material, so that the device forms a flexible connecting vessel system. When in use, the connecting conduit 2 can be reserved longer to adapt to legs with different spacings. Moreover, the flexible connecting conduit 2 ensures that the overall flexibility can be rolled and retracted to suit various environments, and can be combined with a two-way joint for temporary extension or cut for maintenance as needed.

[0033] A further improvement is that the front side of the liquid level scale tube 1 is an arc surface, preferably a semicircular arc surface, so as to facilitate observation of the degree on the scale line in all directions within 180° of the front side.

[0034] A further improvement is that the scale line 3 is arranged on the inner wall of the liquid level scale tube 1, so that it is not easily contaminated or damaged, and the scale line is a closed-loop scale line. The scale line 3 is drawn alternately in two different colors, which is easy to observe and read the height difference between the liquid level of the scale tube and the elevation of the top of the embedded leg of the tower crane foundation. The spacing between two adjacent scale lines is preferably 1mm.
