Description

Technical Field

[0001] The utility model relates to the technical field of silo slipform construction, in particular to a device for monitoring the verticality and torsion of a slipform in silo slipform construction. Background Art

[0002] During silo slipform construction, as the construction progresses, the slipform used in the construction may deviate or twist during the climbing process, which makes the quality of the silo slipform construction unable to be guaranteed. Among the existing silo slipform construction monitoring devices or methods, there are few methods that can simultaneously monitor verticality and torsion, which will cause some problems when using traditional construction methods.

[0003] First, the method of using a pendulum to measure verticality has obvious defects. This method requires the installation of multiple pendulums, which not only increases the equipment cost and maintenance difficulty, but is also easily affected by weather, resulting in large measurement errors. On the other hand, the complexity of the theodolite's torsion observation is also a prominent challenge. Each observation requires centering and leveling, which makes the operation cumbersome and complicated, causing operators to make mistakes during the centering and leveling process, or increase the time consumption of the entire measurement process. Therefore, we urgently need to find more efficient and accurate measurement methods to meet these challenges. Such methods should be able to improve the accuracy of measurements, reduce the complexity of equipment and operations, and meet the needs of modern engineering and scientific fields for precise measurements.

[0027] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0028] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0029] like Figure 1 and Figure 2 As shown, the utility model provides a device for real-time monitoring of verticality and torsion of a silo sliding form, and its components include: a supporting member 1 and a sliding rod 2.

[0030] like Figure 1 As shown, the support member 1 is suspended at the bottom of the slipform platform 4 through the suspension rod 14, and the slipform platform 4 is installed on the top of the lower layer of the poured concrete warehouse wall 3 through the slipform 41. The support member 1 and the lower layer of the poured concrete warehouse wall 3 are relatively vertically arranged.

[0031] like Figure 2As shown, the support member 1 is composed of the upper bearing plate 12, the lower bearing plate 15, the first end 11 away from the poured concrete silo wall, and the second end 13 close to the poured concrete silo wall, and is suspended at the bottom of the slipform platform by the suspension rod 14. A hole is opened in the middle of the first end 11, and a transverse rectangular long slit is opened in the middle of the second end 13.

[0032] like Figure 2 As shown, the slide bar is composed of the long bar 24, the elastic member 21, the limit plate 22, and the pulley 25. The elastic member 21 is a coil spring, which is movably mounted on the front end of the limit plate of the long bar 24, and the front end of the elastic member 21 is connected to a ring 26 with a larger diameter than the coil spring. The coil spring is pressed against the lower layer of the poured concrete warehouse wall 3 by the ring 26 and the limit plate 22. The long bar 24 is engraved with scales at the rear end of the limit plate. The end of the long bar 24 fixes the pulley 25 at the end through a columnar shaft 27 so that the pulley can rotate at the end of the bar.

[0033] The installation method of the utility model is to suspend the utility model at the bottom of the slipform platform after the poured concrete silo wall reaches a certain height, and vertically mortgage the support member 1 on the poured concrete silo wall. At this time, the scale on the long rod should be recorded and the long rod should be kept in the middle of the second end of the support member.

[0034] The specific steps are as follows:

[0035] 1. Casting of bottom bulkhead;

[0036] 2. After the cast warehouse wall reaches the strength allowed by the construction and reaches a certain height, the support is suspended at the bottom of the sliding membrane platform through the hanging column, and the second end of the support is vertically arranged with the cast warehouse wall. The elastic member in the support pushes the slide bar to make the pulley at the extended end of the slide bar press against the lower cast warehouse wall, and the scale on the slide bar is recorded;

[0037] 3. After the device is installed, record the scale of the slide rod at the sliding joint, and place the slide rod in the middle of the sliding joint. Continue to pour the sliding formwork upward layer by layer on the basis of the bottom warehouse wall. Before each climb, observe the scale of the slide rod at the sliding joint and whether lateral movement occurs at the sliding joint. If movement occurs, the sliding formwork can be adjusted according to the initial slide rod scale.

[0038] The method of using the utility model is as follows: when the slipform construction starts, if the slipform platform shifts sideways, it can be observed that the scale on the long rod changes. At this time, the lateral displacement of the slipform platform can be adjusted according to the size of the change in the scale on the long rod. If the slipform platform shifts sideways and twists at the same time, it can be observed that the long rod moves to the left or right in the middle of the second end of the support and the scale on the long rod also changes. At this time, the torsion angle of the slipform platform and the length of the lateral displacement can be calculated according to the similarity of the triangles, so that timely corrections can be made according to the data.

[0039] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
