Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a verticality monitoring system for a shallow circular warehouse wall of a grain depot. Background Art

[0002] A shallow silo is a cylindrical ground silo with a ratio of silo wall height to inner diameter less than 1.5. It is widely used in the grain industry due to its small footprint, large diameter, high grain pile, large silo capacity, reasonable structural force, strong earthquake resistance, good sealing performance, easy mechanized operation, and convenience for the implementation of grain "scattered" operations.

[0003] Slipform construction is the main construction method for shallow silos, which has the advantages of high mechanization, fast construction speed, small site occupation, guaranteed safe operation and significant comprehensive benefits. Due to the large diameter of the silo, the platform is greatly affected by its own weight, construction live load, concrete friction and various additional loads. Therefore, it is easy for the slipform to shift and deform, which will affect the verticality of the inner wall of the shallow silo, causing the verticality of the structure to exceed the verticality, serious torsional deviation, and even the inability to continue sliding.

[0004] Therefore, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the prior art. Utility Model Content

They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. The terms "connected" and "connection" used in the present invention should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0027] like Figure 1-2 As shown, a verticality monitoring system for a shallow circular silo wall of a grain depot is provided. Monitoring mechanisms are evenly distributed on the inner wall of a sliding formwork inner template 1. The verticality of the silo wall is monitored by the monitoring mechanisms. The monitoring mechanisms include a connecting rod 2 and a monitoring end. The connecting rod 2 can be a hollow metal rod or a wooden rod. The connecting rod 2 is fixed to the inner wall of the sliding formwork inner template 1. The upper end of the connecting rod 2 is detachably connected to the inner wall of the sliding formwork inner template 1. For example, a connecting bolt is arranged on the sliding formwork inner template 1 to fix the connecting rod 2. After the casting of the lowest section of the silo wall is completed and the sliding form is moved upward, the connecting rod 2 is fixed. The connecting rod 2 extends downward in a direction parallel to the axis (longitudinal direction) of the shallow circular silo. The monitoring end is connected to the lower end of the connecting rod 2. The monitoring end is in contact with the inner side of the cast silo wall. The silo wall is monitored by the monitoring end during the sliding of the sliding formwork, so that the verticality of the silo wall of the section to be cast can be accurately grasped to ensure the verticality of the silo wall construction.

[0028] In an optional embodiment, the monitoring end includes a main body 5, a slide rod 6, and a monitoring element 8. The main body 5 is connected to the lower end of the connecting rod 2, and the main body 5 is used to connect the slide rod 6. A center hole extending radially along the shallow circular silo is provided inside the main body 5. The main body 5 can be a square or round tube. The slide rod 6 extends axially along the center hole and is slidably assembled along its axial direction. A buffer spring 7 corresponding to the slide rod 6 is provided at the end of the center hole away from the cast silo wall. The buffer spring 7 squeezes the other end of the slide rod 6 to contact the inner side of the cast silo wall, thereby keeping the slide rod 6 able to continuously adhere to the silo wall. A monitoring element 8 is provided on the inner wall of the center hole, and multiple monitoring elements 8 are evenly distributed along the radial direction of the shallow circular silo to determine the position of the slide rod 6 through the monitoring element 8. Specifically, the slide rod 6 can be a metal rod, and the detection element can be a Hall element, a touch switch, an infrared rangefinder or other detection device, as long as it can detect the relative sliding position of the slide rod 6.

[0029] For example, a plurality of touch switches are provided on the inner wall of the central hole, and the displacement of the slide bar 6 is determined according to the relative positions of the different touch switches, so as to judge whether the specific slide mold is tilted.

[0030] In actual use, by moving the sliding form upward, the sliding rod 6 can provide driving force through the buffer spring 7 during the movement. By monitoring the relative position of the sliding rod 6, if the sliding form tilts inward, the distance between the lower end of the sliding rod 6 and the warehouse wall changes, so it can be judged whether the sliding form is tilted. Then the technicians can adjust the sliding form according to needs to ensure the casting quality.

[0031] In an optional embodiment, the monitoring terminal further includes a controller, which may be a single chip microcomputer or a PLC, the monitoring element 8 is electrically connected to the controller, and the controller is correspondingly connected to the controller, so that an intuitive display can be achieved.

[0032] An articulated seat is provided at one end of the slide bar 6 close to the cast warehouse wall, so that the slide bar 6 can be rotatably connected to the pulley 3 through the articulated seat, so as to slide along the cast warehouse wall through the pulley 3, thereby reducing the friction during the sliding process and ensuring the accuracy of use.

[0033] In an optional embodiment, a plug 9 is provided at one end of the center hole away from the cast warehouse wall, and the outer wall of the plug 9 is provided with threads, so that it is connected to the center hole through a threaded connection, and the buffer spring 7 is correspondingly arranged between the slide rod 6 and the plug 9 so that the slide rod 6 has a tendency to move toward the cast warehouse wall.

[0034] The inner wall of the center hole is provided with an external thread corresponding to the plug 9, and the plug 9 can be adjusted according to actual needs.

[0035] In an optional embodiment, the slipform includes a plurality of groups of unit molds spliced ​​together, and each unit mold is provided with a corresponding monitoring mechanism, which can monitor each unit mold, so as to accurately determine the unit mold to be adjusted. In order to ensure smooth and accurate sliding of the pulley 3, the outer edge of the pulley 3 is provided with an arc surface corresponding to the inner wall of the cast warehouse wall to prevent the pulley 3 from damaging the inner surface of the warehouse wall.

[0036] In an optional embodiment, the monitoring system also includes a displacement sensor, which is electrically connected to a controller. The so-called electrical connection includes a connection in the form of a data line to meet data transmission requirements. A displacement sensor is provided on the monitoring end, which is electrically connected to the controller for monitoring each displacement sensor and monitoring the radial position of each unit mold to avoid deformation of the sliding mold shape.

[0037] A three-dimensional scanner 4 is arranged in the middle of the shallow circular silo to scan and measure the inner wall of the poured part. The characteristics of the three-dimensional laser scanning technology, such as fast data collection speed, high data accuracy and wide data collection range, are utilized to measure the poured part in real time. By comparing the data with the built three-dimensional digital model, it is concluded whether the verticality of the poured part of the shallow circular silo meets the design requirements.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
