Description

Technical Field

[0001] This utility model relates to the field of slipform lifting technology for large building construction, and in particular to a slipform jack that integrates force and displacement. Background Technology

[0002] Slipform lifting construction technology for large buildings is an important mechanized construction process in the overall lifting system of slipform frames for rapid building construction. Its core lies in using slipform hydraulic jacks as the lifting power, enabling the formwork system to slide continuously along the newly poured concrete surface, thus achieving highly efficient continuous operation. This technology is widely used in shallow circular grain silos, chimneys, water towers, high bridge piers, and gate piers in water conservancy projects.

[0003] Currently available slipform construction platform lifting equipment lacks synchronous control and lifting force monitoring functions, and also lacks effective means to monitor the structural posture during construction, making it difficult to determine whether the slipform system is in a healthy operating state. Furthermore, the entire process still relies heavily on manual operation, and construction safety and quality largely depend on the professional level of the operators. In recent years, the industry has placed increasing emphasis on safe production, and the existing slipform process has many safety hazards that cannot be effectively monitored or resolved, making the improvement and upgrading of the slipform process imperative.

[0004] Therefore, ensuring the balanced force and synchronized height of each lifting point during the lifting process of the slipform construction platform, effectively monitoring the stress state of the jacks or supporting gantry, and conducting comprehensive attitude deviation detection of the structure under construction have become key issues for achieving safe, real-time, and online monitoring of lifting construction. Summary of the Invention

[0005] Therefore, this utility model provides a sliding mold jack that integrates force and displacement, which effectively improves the synchronization of various points during sliding mold operation, the monitoring of lifting force, and the all-round real-time monitoring of the posture of the lifting body.

[0006] To solve the above-mentioned technical problems, this utility model provides a sliding mold jack that integrates force and displacement, comprising: Base connecting plate; A force sensor, which is connected to the base connecting plate; The jack body includes a sliding jack base, and the force sensor is connected to the sliding jack base; A sensor mounting plate, which is connected to the sliding mold jack; A balance plate, which is connected to the top of the sliding mold jack; A displacement sensor is installed between the sensor mounting plate and the balance top plate; A guide structure is provided between the sensor mounting plate and the balance top plate to limit the rotation of the balance top plate during the sliding process.

[0007] In one embodiment of this utility model, a guide sleeve and a guide stud are further included. The guide sleeve is installed on the balance top plate, and the guide stud is installed on the sensor mounting plate and is inserted into the guide sleeve.

[0008] In one embodiment of this utility model, a corrugated pipe is also included, which is installed on the balance top plate and covers the displacement sensor.

[0009] In one embodiment of this utility model, a displacement sensor protective shell is also included, which is connected to the sensor mounting plate; The displacement sensor is disposed and installed inside the displacement sensor protective housing.

[0010] In one embodiment of this utility model, the sensor mounting plate is connected to the threaded hole of the handle on the main body of the jack.

[0011] In one embodiment of this utility model, a protective cover is also included. The protective cover is connected to the balance top plate and is located on the side close to the displacement sensor to form a shielding protection for the displacement sensor.

[0012] In one embodiment of this utility model, the balance plate is connected to the top of the jack body by welding.

[0013] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art: This utility model discloses a slipform jack that integrates force and displacement. By incorporating force sensors, it can monitor the real-time weight at various points during slipform construction, preventing slipform failure due to jack malfunction causing uneven weight distribution and hindering slipform installation. Displacement sensors ensure consistent slipform height at all points, enabling comprehensive posture deviation detection of the structure under construction. It achieves continuous concrete pouring by using a hydraulic system to drive the jacks in a cyclical lifting motion of the formwork and construction platform. Furthermore, it effectively improves the synchronization of slipform installation, monitoring of lifting force, and comprehensive real-time monitoring of the lifting body's posture, reducing the time spent manually measuring verticality and significantly increasing work efficiency. It features formwork saving and rapid construction. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0019] In this utility model, when directions (up, down, left, right, front, and back) are described, it is only for the convenience of describing the technical solution of this utility model, and does not indicate or imply that the technical features referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

In the description of this utility model, if "first" or "second" is used, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features.

[0021] In this utility model, unless otherwise explicitly defined, terms such as "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; a fixed connection, a detachable connection, or an integrally formed connection; a mechanical connection, an electrical connection, or a connection capable of mutual communication; or the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model based on the specific content of the technical solution.

[0022] Reference Figure 1 , Figure 2 As shown, this utility model discloses a sliding mold jack that integrates force and displacement, comprising: The base connecting plate 8 is used to connect to the lifting frame (template, operating platform) by bolts; Force sensor 7, which is connected to the base connecting plate 8; The jack body 6 includes a sliding jack base, and the force sensor 7 is connected to the sliding jack base. Sensor mounting plate 5, which is connected to the sliding jack; Balance plate 1, which is connected to the top of the sliding mold jack; Displacement sensor 9 is installed between the sensor mounting plate 5 and the balance top plate 1; A guide structure 10 is disposed between the sensor mounting plate 5 and the balance top plate 1 to limit the rotation of the balance top plate 1 during the sliding process.

[0023] It should be noted that the force sensor 7 is used to output a force signal representing the lifting gravity, and the displacement sensor 9 is used to output a displacement signal representing the lifting displacement stroke, so as to monitor the force balance and height synchronization during the slipforming process. By setting the force sensor 7, the real-time weight at each point can be monitored during the climbing formwork to prevent a jack failure that could cause the formwork to tilt and the weight distribution to become unbalanced, thus preventing slipforming. The displacement sensor 9 ensures the consistency of the slipforming height at each point and enables all-round attitude deviation detection of the structure under construction.

[0024] In one embodiment, the system further includes a guide sleeve 101 and a guide stud 501. The guide sleeve 101 is mounted on the balance plate 1, and the guide stud 501 is mounted on the sensor mounting plate 5 and is inserted into the guide sleeve 101 to provide guiding constraints to the balance plate 1 and reduce the risk of attitude deviation during the sliding mode process.

[0025] In one embodiment, a bellows 3 is also included, which is installed on the balance top plate 1 and covers the displacement sensor 9 for waterproof and dustproof sealing protection of the displacement sensor 9.

[0026] In one embodiment, a displacement sensor protective housing 4 is also included, which is connected to the sensor mounting plate 5. The displacement sensor 9 is disposed and installed inside the displacement sensor protective housing 4.

[0027] In one embodiment, the sensor mounting plate 5 is connected to the threaded hole of the handle on the jack body 6 to achieve detachable fixing of the sensor mounting plate 5.

[0028] In one embodiment, a protective cover 2 is also included, which is connected to the balance top plate 1 and is located on the side close to the displacement sensor 9 to form a shielding protection for the displacement sensor 9.

[0029] In one embodiment, the balance plate 1 is connected to the top of the jack body 6 by welding; the base connecting plate 8 is connected to the sliding jack by bolts; and the bellows 3 is fixed to the balance plate 1 with screws.

[0030] In use, the pre-embedded steel pipe is inserted into the top of the slipform jack and fixed to the lifting frame via the base connecting plate 8. The slipform jack is then connected to the oil pipe. During climbing, the slipform jack climbs on the pre-embedded steel pipe, driving the lifting frame, formwork, and operating platform upward together. Force sensor 7 monitors in real time whether the lifting gravity at each point is consistent to prevent tilting; displacement sensor 9 monitors the displacement stroke of the balance top plate 1 to control the consistent climbing height at each point. After all jacks have climbed to the designated height, they are locked, and then slurry is poured in, ensuring that new slurry is applied before the lower layer has initially set.

[0031] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
