Description

Technical Field

[0001] This utility model relates to the field of silo construction technology, and specifically to a safety monitoring device for silo construction. Background Technology

[0002] Silos, also known as round silos, are cylindrical above-ground grain silos with a wall height to inner diameter ratio of less than 1.5. Due to their advantages such as small footprint, large diameter, high grain stack, large storage capacity, reasonable structural stress, strong earthquake resistance, good sealing performance, ease of mechanization, and facilitating the implementation of "scattered" grain operations, they are widely used in the grain industry.

[0003] Slipform construction is the main construction method for cylindrical silos. It has the advantages of high mechanization, fast construction speed, small site occupation, guaranteed safe operation, and significant comprehensive benefits. However, due to the large diameter of the silo, the slipform platform is greatly affected by its own weight, construction live load, concrete friction resistance, and various additional loads. When the slipform moves upward, it is prone to displacement and deformation, which in turn leads to changes in the verticality and horizontality of the slipform. Therefore, it is necessary to use safety monitoring devices to monitor the verticality and horizontality of the slipform.

[0004] Existing safety monitoring devices have been found to have high hardware costs in actual use. Their core monitoring components rely on high-precision instruments, making them difficult to popularize in large-scale monitoring scenarios. In addition, the later maintenance costs are high and the practicality is low. Therefore, improvements are needed.

[0005] Therefore, it is necessary to invent a safety monitoring device for silo construction. Summary of the Invention

[0006] Therefore, this utility model provides a safety monitoring device for silo construction to solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a safety monitoring device for silo construction, comprising a base plate, a U-shaped rod on the top of the base plate, a housing fixedly connected to the top of the base plate, both sides of the housing being open, the housing being sleeved on the outside of the U-shaped rod, a rotating shaft connected to the U-shaped rod, and a roller fixedly sleeved on the outside of the rotating shaft.

[0008] A cover plate is provided on one side of the housing. A spring is fixedly connected to one side of the U-shaped rod, and one end of the spring is in contact with the cover plate. A connecting block is fixedly connected inside the housing. A pressure sensor is fixedly embedded on the connecting block. A moving block is fixedly connected inside the U-shaped rod. The moving block is in contact with one side of the pressure sensor. A stop bar is fixedly connected inside the housing. The stop bar is in contact with the inner wall of one side of the U-shaped rod.

[0009] Preferably, the U-shaped rod is in sliding contact with the housing.

[0010] Preferably, the cover plate is connected to the housing by bolts.

[0011] Preferably, the spring is in a compressed state.

[0012] Preferably, a movable rod is fixedly connected to one side of the U-shaped rod, and the movable rod passes through the cover plate and slides in contact with it.

[0013] Preferably, a groove is provided on the front side of the movable rod, and a scale is fixedly connected in the groove.

[0014] Preferably, two support blocks are fixedly connected to one side of the base plate, and a camera is fixedly embedded on the two support blocks, with the lens of the camera located directly in front of the scale.

[0015] Preferably, two mounting brackets are fixedly connected to the top of the base plate, and each mounting bracket has multiple mounting holes.

[0016] Preferably, the rotating shaft is connected to the U-shaped rod via a bearing.

[0017] The beneficial effects of this utility model are:

[0018] This invention utilizes components such as rollers, U-shaped rods, and pressure sensors. When in use, pressure applied to the rollers causes the U-shaped rods to move towards the pressure sensor, thereby squeezing the sensor. This allows for the monitoring of the verticality and horizontality of the sliding mold. Furthermore, the only detection instrument used in this device is the pressure sensor, which reduces hardware costs and overall device cost. This makes it widely applicable and highly practical.

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] See attached document Figure 1 - Appendix Figure 6 The present invention provides a safety monitoring device for silo construction, comprising: 1. a base plate 1, a U-shaped rod 2 on the top of the base plate 1, a housing 3 fixedly connected to the top of the base plate 1, both sides of the housing 3 being open, the housing 3 being sleeved on the outside of the U-shaped rod 2, a rotating shaft 4 connected to the U-shaped rod 2, and a roller 5 fixedly sleeved on the outside of the rotating shaft 4;

[0030] A cover plate 6 is provided on one side of the housing 3. A spring 7 is fixedly connected to one side of the U-shaped rod 2 and one end of the spring 7 is in contact with the cover plate 6. A connecting block 8 is fixedly connected inside the housing 3. A pressure sensor 9 is fixedly embedded on the connecting block 8. A moving block 10 is fixedly connected inside the U-shaped rod 2 and is in contact with one side of the pressure sensor 9. A stop bar 11 is fixedly connected inside the housing 3 and is in contact with one side of the inner wall of the U-shaped rod 2.

[0031] U-shaped rod 2 slides in contact with housing 3, cover plate 6 is connected to housing 3 by bolts, and spring 7 is compressed.

[0032] In this implementation scheme, components such as roller 5, U-shaped rod 2, and pressure sensor 9 are designed. When in use, the roller 5 is subjected to pressure, which causes the U-shaped rod 2 to move toward the pressure sensor 9, thereby squeezing the pressure sensor 9, thus realizing the monitoring of the verticality and horizontality of the sliding mold 20.

[0033] To achieve the monitoring objective, this device employs the following technical solution: A movable rod 12 is fixedly connected to one side of the U-shaped rod 2. The movable rod 12 passes through the cover plate 6 and slides in contact with it. A groove 13 is provided on the front side of the movable rod 12, and a scale 14 is fixedly connected in the groove 13. Two support blocks 15 are fixedly connected to one side of the base plate 1, and a camera 16 is fixedly embedded on the two support blocks 15. The lens of the camera 16 is located directly in front of the scale 14. When the roller 5 is squeezed, causing the U-shaped rod 2 to move, the movable rod 12 can also move, thereby causing the scale 14 to move. In this way, the extended length of the scale 14 will increase. In addition, the camera 16 can record the extended length of the scale 14 in real time. Thus, when monitoring verticality and horizontality, the extended length of the scale 14 can also be used for monitoring. This ensures that the monitoring work can continue even when the pressure sensor 9 is damaged. The camera 16 can also be wirelessly connected to a computer.

[0034] To achieve the purpose of installation, the device adopts the following technical solution: two mounting brackets 17 are fixedly connected to the top of the base plate 1, and multiple mounting holes 18 are opened on the two mounting brackets 17.

[0035] In order to reduce wear, the device adopts the following technical solution: the rotating shaft 4 and the U-shaped rod 2 are connected by bearings.

[0036] The usage process of this utility model is as follows: Since slipform construction is a special process for efficiently constructing concrete silos 19 (such as grain silos, storage silos, etc.), its core is to use a set of template systems that can slide continuously along the silo wall. By pouring concrete in layers (each layer is usually 30-50 cm high) and simultaneously lifting the template (with the help of jacks and other equipment), the silo structure is formed from bottom to top in one go. This process carries out the template support and concrete pouring at the same time, eliminating the cumbersome steps of template disassembly and assembly in the traditional process. It has the advantages of fast construction speed (it can be raised 2-4 meters per day), strong structural integrity, and saving materials and labor. It is especially suitable for circular storage buildings with high height and large diameter. However, it has extremely high requirements for the control of the initial setting time of concrete, the monitoring of the verticality of the template and the synchronization of the lifting equipment. A professional team is required to control the construction accuracy throughout the process.

[0037] During the construction of silo 19, this device can be installed on the sliding mold 20 using bolts with the help of the mounting frame 17 and mounting holes 18. During installation, the rollers 5 are made to contact the silo wall of silo 19. Using the same principle, multiple devices are installed on the sliding mold 20. During installation, the angle between the multiple devices is the same, that is, the multiple devices are evenly distributed on the silo body in a circular shape. In this way, when the sliding mold 20 is lifted, it can drive multiple devices to move upward synchronously. Since the rollers 5 in multiple devices are in contact with the silo wall, when the sliding mold 20 tilts upward, one roller 5 will always be squeezed. This will cause the U-shaped rod 2 and the moving block 10 to move towards the pressure sensor 9. Then the moving block 10 can squeeze the pressure sensor 9. When the value of one of the pressure sensors 9 changes, it indicates that the sliding mold 20 tilts upward. Then, the technicians can adjust the sliding mold 20 as needed to ensure the pouring quality.

[0038] In addition, the pressure sensor 9 used in this device can be wirelessly connected to a computer, so that the value of the pressure sensor 9 can be displayed on the computer in real time, which makes it convenient for staff to know whether the value has changed immediately.

[0039] In this application, the model and specifications of the pressure sensor 9 and camera 16 need to be selected and determined according to the actual specifications of the entire device. Moreover, the above-mentioned components are very mature products in the prior art, so the specific model and specifications will not be described in detail. In addition, the electrical control principle and wireless connection of the above-mentioned components are clear to those skilled in the art, so the control method and connection will not be described in detail.

[0040] The above are merely preferred embodiments of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model shall fall within the scope of protection claimed by this utility model.
