Description

Technical Field

[0001] This utility model relates to the field of infrastructure technology and can also be applied to structural engineering fields such as highways, municipal works, buildings, water conservancy, and wind power. Specifically, it relates to a prefabricated measurement and control device. Background Technology

[0002] In bridges or building structures, to adapt to the effects of climate (such as temperature changes and air pressure fluctuations) and uneven stress, resulting in horizontal displacement, rotation, and vibration reduction, bearings are needed to reliably transfer the reaction force of the superstructure to the substructure, thereby mitigating and eliminating the impact of superstructure deformation on the substructure. Generally, bearings are required to withstand vertical loads and possess rotational and horizontal displacement capabilities. In most cases, conventional spherical bearings already possess these functions and meet engineering design requirements. However, to enhance the functionality of the bearings, existing spherical bearings have added a height adjustment function, typically using wedge blocks. The drive device (hydraulic cylinder) that causes the wedge blocks to slide relative to each other is usually directly fixed between the wedge blocks, resulting in limited space, time-consuming and labor-intensive loading and unloading of the power source, and low efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a prefabricated measurement and control device. The drive device is prefabricated and installed at the end of the adjustment block and located on the outside of the device body, which facilitates quick loading and unloading, saves time and effort, and has high loading and unloading efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following solution: An assembled measurement and control device includes a device body, characterized in that the device body includes an upper plate, a lower plate, and an adjusting block, the adjusting block is movably disposed between the upper plate and the lower plate, the adjusting block slides relative to the upper plate and the lower plate to change the height of the device body, and the end of the adjusting block is detachably connected to a mounting part for mounting a driving device, the mounting part being located on the outside of the device body.

[0005] In this design, the adjusting block cooperates with the upper and lower plates and slides relative to them, converting horizontal movement into vertical displacement of the upper plate, thereby adjusting the height of the device body. The mounting part is detachably installed at the end of the adjusting block and is used to connect the drive unit. Located on the outside of the device body, the mounting part provides greater operating space for the installation and removal of the drive unit, eliminating the need for operators to work in narrow or dangerous spaces, significantly improving construction safety and efficiency. The drive unit is easy to install and remove without disassembling the support or affecting the upper structure. It is only installed when adjustment is needed and can be removed after adjustment, avoiding long-term space occupation and environmental corrosion, thus extending its service life. The mounting part is assembled and connected to the adjusting block, making the installation and removal of the drive unit quick, time-saving, and labor-saving, improving efficiency. Furthermore, damaged individual components (such as the adjusting block and mounting part) can be replaced individually, reducing maintenance costs.

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0023] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "longitudinal", "lateral", "horizontal", "inner", "outer", "front", "rear", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "have," "install," "connect," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0025] An assembled measurement and control device includes a device body, characterized in that the device body includes an upper plate 2, a lower plate 10 and an adjusting block 3, the adjusting block 3 is movably disposed between the upper plate 2 and the lower plate 10, the adjusting block 3 slides relative to the upper plate 2 and the lower plate 10 to change the height of the device body, and the end of the adjusting block 3 is detachably connected to a mounting part 4 for mounting a driving device 5, the mounting part 4 being located on the outside of the device body.

[0026] In this embodiment, as Figure 10 As shown, support 1 is set on the bottom surface of lower plate 10. Lower plate 10 and support 1 are integrally formed, that is, lower plate 10 is equivalent to the top panel of support 1. Support is the main load-bearing structure, which transfers the upper load to the lower foundation. The upper load is generally generated by the beam, and the lower foundation is generally a pier. Support 1 can be a spherical steel support, friction pendulum support, etc.

[0027] like Figure 1 As shown, the upper plate 2 directly supports the plate that contacts the upper structure. Changes in its height directly affect the height of the entire support. The adjusting block 3 cooperates with and slides relative to the upper plate 2, converting horizontal movement into vertical displacement of the upper plate 2, thereby adjusting the height. The mounting part 4 is used to connect an external drive device 5 (such as a hydraulic jack). The mounting part 4 is located on the outside of the device body, providing more operating space for operators. This makes operation and maintenance very convenient, without disassembling the support or affecting the upper structure.

[0028] The mounting part 4 is detachably connected to the end of the adjusting block 3, meaning that the drive device 5 is only installed when adjustment is needed and can be removed after adjustment. This avoids long-term space occupation and environmental corrosion, thus extending its service life. The assembly-type connection between the mounting part 4 and the adjusting block 3 makes the installation and removal of the drive device 5 quick, time-saving, and labor-saving, improving installation and removal efficiency. Work process: Position the support in the predetermined position, connect the drive device 5 to the mounting part 4 on the outside of the support, start the drive device 5, drive the adjustment block 3 to move, and the relative sliding between the adjustment block 3 and the upper plate 2 causes the upper plate 2 to rise or fall, thereby adjusting the support height of the support. After the adjustment is in place, remove the drive device 5.

[0029] In summary, the detachable connection between the mounting part 4 and the end of the adjusting block 3 in this embodiment eliminates the need for operators to work in narrow or dangerous spaces, greatly improving construction safety and efficiency. The prefabricated concept fully conforms to the prefabricated spirit of modern building industrialization, facilitating rapid installation, adjustment, and subsequent maintenance, shortening the construction period. When a single component (such as the adjusting block 3 or the mounting part 4) is damaged, it can be replaced individually, reducing maintenance costs.

[0030] Furthermore, the mounting part 4 is disposed at both ends of the long side of the adjusting block 3.

[0031] Specifically, such as Figure 4 and 7 As shown, by installing drive devices 5 at both ends of the adjusting block 3, it can be ensured that the adjusting block 3 is subjected to uniform force during movement, avoiding problems such as jamming or one-sided wear. If only one side is subjected to force, the long strip-shaped adjusting block 3 is prone to tilting due to uneven friction during sliding and getting stuck in the guide groove 7. Dual-sided drive ensures the smoothness of linear motion, and the balanced driving force makes the contact surface between the adjusting block 3 and the upper plate 2 more uniformly subjected to force, reducing unnecessary internal stress concentration and improving the durability of the component.

[0032] In a narrow construction space, there may only be operating space on one side of the support. With installation parts 4 at both ends, operators have the flexibility to choose the most convenient side to operate according to the site conditions. For large or critical projects, drive devices 5 can be installed at both ends to achieve a higher level of synchronous control and drive, ensuring that nothing goes wrong.

[0033] If one end of the mounting section 4 is accidentally damaged after long-term use, the operator can immediately use the other end of the mounting section 4 to complete the adjustment task without affecting the project progress. This greatly enhances the fault tolerance and maintainability of the support. In systems that require simultaneous jacking of multiple supports (such as building jacking and correction), sensors and drive devices 5 can be installed at both ends of the adjustment block 3 of each support. The control system can compare the displacement or pressure data at both ends to ensure that each adjustment block 3 is in an absolutely horizontal state, thereby achieving high-precision synchronous control of the entire jacking process.

[0034] Furthermore, a limiting element is connected in series at the end of the pressure sensor 9, and the limiting element is a limiting block.

[0035] Specifically, the limiting component is actually a limiting block, which (not shown in the figure) is connected in series to the end of the pressure sensor 9. After the height of the device body is adjusted, the limiting block limits the position of the two adjusting blocks 3.

[0036] If there is no force measurement and only the height is adjusted, there will only be a limit block between the two adjustment blocks 3 to limit the horizontal distance between the two adjustment blocks 3, so as to achieve the constraint fixation after the height of the device body is adjusted.

[0037] Furthermore, the mounting part 4 includes a first fixing plate 41 and a first mounting plate 42. The first fixing plate 41 is disposed at both ends of the length side of the adjusting block 3 and is located on the outside of the device body. The first mounting plate 42 is detachably connected to the first fixing plate 41. The driving device 5 is disposed between the two first mounting plates 42 located on the same side of the device body. One of the first mounting plates 42 at the end of the upper plate 2 is provided with bolt holes 423 for connecting the driving device 5.

[0038] Specifically, such as Figure 4 , Figure 5 , Figure 6 As shown, the first fixing plate 41 is directly fixed at both ends of the length direction of the adjusting block 3. It is generally welded or integrally formed. The first fixing plate 41 is located on the outside of the device body. It is the connection base and load-bearing base between the entire mounting part 4 and the adjusting block 3 body.

[0039] The first mounting plate 42 is detachably connected to the first fixed plate 41. The first mounting plate 42 is the direct mounting platform of the drive device 5. On one of the two opposing first mounting plates 42 on the same side of the device body, bolt holes 423 for connecting the drive device 5 are provided. The drive device 5 is rigidly fixed to the first mounting plate 42 by bolts. The drive device 5 is placed horizontally, with one end (piston rod) pressing against (or connected to) one first mounting plate 42 and the other end connected to the other first mounting plate 42. When the drive device 5 works, it generates a pushing or pulling force that acts directly on the two first mounting plates 42, thereby driving the entire adjusting block 3 to move horizontally.

[0040] Workflow: First, install the two first mounting plates 42 onto the first fixed plates 41 at both ends of the adjusting block 3. Then, place the driving device 5 between the two first mounting plates 42 and securely install it on the first mounting plate 42 with bolt holes 423 using bolts. A sliding support can be used on the other side to allow for length changes and free rotation. Activating the driving device 5 causes its piston rod to extend or retract. The force generated by the driving device 5 is transmitted to the first fixed plate 41 through the first mounting plate 42, and then directly acts on the end of the adjusting block 3 by the first fixed plate 41. This horizontal force pushes the adjusting block 3 to slide horizontally, and through the inclined plane, it is ultimately converted into the vertical movement of the upper plate 2, thus achieving height adjustment of the support. When it is necessary to disassemble the driving device 5, simply detach the first mounting plate 42 from the first fixed plate 41; this is convenient, quick, and saves time and effort.

[0041] Furthermore, the end face of the first fixing plate 41 away from the adjusting block 3 is provided with an assembly groove 411, and the end of the first mounting plate 42 is provided with an assembly block 421 that is adapted to the assembly groove 411. The assembly block 421 is inserted into the assembly groove 411 along the length direction of the adjusting block 3, and the assembly block 421 is locked to the first fixing plate 41 by a screw.

[0042] Specifically, the assembly groove 411 is formed on the end face (i.e., outer side) of the first fixed plate 41 away from the adjusting block 3. It acts as the "female head" for precise positioning and accommodating the first mounting plate 42. The assembly block 421 is set at the end of the first mounting plate 42. It acts as the "male head". Its shape and size are precisely adapted to the assembly groove 411. Along the length direction of the adjusting block 3 (i.e., the horizontal direction), the assembly block 421 is inserted into the assembly groove 411. This action completes the initial positioning and the transmission of the main shearing force. This insertion method can be operated in a relatively narrow space, with less demand on vertical space. After the assembly block 421 is inserted into the assembly groove 411, the locking bolt passes through the first fixed plate 41 and the assembly block 421 vertically or laterally (or applies a huge clamping force) to rigidly lock the two together, eliminating all degrees of freedom and forming a whole.

[0043] The assembly slot 411 and the assembly block 421 constitute a positioning feature. During installation, they can automatically guide the first mounting plate 42 to the correct position, ensuring that the drive device 5 is aligned with the axis of the adjusting block 3 after installation, thus avoiding a tedious adjustment process. The huge horizontal thrust / pull force generated by the drive device 5 will first manifest as a shear force acting on the connecting surface. The mating surfaces of the assembly slot 411 and the assembly block 421 are the main structures for bearing and transmitting this shear force. This method of transmitting the main force through surface-to-surface contact, rather than relying entirely on the shear resistance of the screw, greatly improves the rigidity and reliability of the connection.

[0044] Since the shear force is absorbed by the slotted block structure, the main task of the screw changes from bearing shear to providing a huge clamping force. The clamping force resists minor displacements and vibrations through friction and ensures that the first mounting plate 42 and the first fixing plate 41 fit tightly and do not separate. When disassembly is required, simply loosen the screw to pull the first mounting plate 42 out horizontally. This sliding insertion method is easier to align and disassemble than simply stacking and connecting with bolts.

[0045] Workflow: First, align the assembly block 421 on the first mounting plate 42 with the assembly groove 411 on the first fixed plate 41. Push the first mounting plate 42 in the horizontal direction (the length direction of the adjusting block 3) to fully insert the assembly block 421 into the assembly groove 411. Install and tighten the screw to make the two rigidly connected as one. Then, place the drive device 5 between the two first mounting plates 42 and fix it in the preset bolt hole 423 with bolts.

[0046] Furthermore, the two opposite sidewalls of the assembly groove 411 are provided with through holes 412, and the sidewall of the assembly block 421 is provided with through holes 422 corresponding to the through holes 412. The screw passes through the through holes 412 and the through holes 422 to connect the assembly block 421 to the first fixing plate 41.

[0047] Specifically, the assembly slot 411 is an outwardly opening U-shape. Through holes 412 are formed on two opposite sidewalls of the assembly slot 411. These through holes 412 appear in pairs, extending from one sidewall to the other, with two through holes 412 from top to bottom, effectively making four through holes 412 on the first fixing plate 41. Through holes 422 are formed on the sidewall of the assembly block 421, precisely aligned with the through holes 412, together forming a complete channel for the screw to pass through. After the assembly block 421 is inserted into the assembly slot 411, the screw is horizontally passed through one through hole 412, then through the through hole 422, and finally out through the other through hole 412, and finally tightened with a nut. The horizontal screw, together with the vertically inserted assembly block 421, forms a robust "cross-shaped" locking structure, which effectively prevents the first mounting plate 42 from moving or detaching from the first fixing plate 41 in any direction (up / down, left / right), providing excellent rigidity.

[0048] Furthermore, the mounting part 4 includes a second fixing plate 43 and a second mounting plate 44. The second fixing plate 43 is disposed at both ends of the length side of the adjusting block 3 and is located on the outside of the device body. The second mounting plate 44 is detachably connected to the second fixing plate 43. The driving device 5 is disposed between the two second mounting plates 44 located on the same side of the device body.

[0049] Furthermore, a pin hole 431 is provided on the second fixing plate 43 near the end of the adjusting block 3. The pin hole 431 passes through the second fixing plate 43 from top to bottom. The second mounting plate 44 is provided with an assembly hole 441 that allows the second fixing plate 43 to be inserted. A matching pin 8 is inserted into the pin hole 431. The pin 8 restricts the second mounting plate 44 from disengaging from the second fixing plate 43.

[0050] Furthermore, the second mounting plate 44 is U-shaped, and the openings of the second mounting plates 44 on the two second fixing plates 43 are opposite to each other. The side wall of the second mounting plate 44 at the end of one of the first adjusting blocks 3 is provided with an assembly cavity 442 for assembling the drive device 5. The drive device 5 is installed in the assembly cavity 442 and fixed with bolts.

[0051] Another embodiment like Figure 7 , Figure 8 , Figure 9As shown, the second fixing plate 43 is similar to the first scheme, fixed at both ends of the length direction of the adjusting block 3, serving as a load-bearing base. It has a pin hole 431 that runs from top to bottom. The second mounting plate 44 is U-shaped and is fitted onto the second fixing plate 43 along the length direction of the adjusting block 3 through the assembly hole 441 on it. The openings of the two second mounting plates 44 are opposite to each other. After the second mounting plate 44 is fitted onto the second fixing plate 43, a pin 8 is inserted into the pin hole 431 on the second fixing plate 43. The pin 8 plays a vertical limiting role, preventing the second mounting plate 44 from detaching upward from the second fixing plate 43. The driving device 5 is embedded in the assembly cavity 442 of one of the second mounting plates 44 and then fixed in the assembly cavity 442 by bolts.

[0052] Workflow assembly: First, the two U-shaped second mounting plates 44 are respectively placed on the corresponding second fixed plates 43 from above, and the pins 8 are inserted to complete the vertical positioning. Then, the drive device 5 is embedded and fixed in the second mounting plate 44 with the assembly cavity 442. When the drive device 5 is started, its piston rod will extend and press against the opposite second mounting plate 44. The second mounting plate 44 where the drive device 5 is located bears the reaction force. This force is transmitted to the second fixed plate 43 through the pins 8. The thrust of the piston rod acts directly on the opposite second mounting plate 44. This force is transmitted through the contact surface between the U-shaped plate structure and the second fixed plate 43, and is finally also transmitted to the second fixed plate 43. Finally, the two second fixed plates 43 are simultaneously subjected to forces in opposite directions, which drives the adjusting block 3 to move and complete the height adjustment.

[0053] The action of inserting and locking the pin is faster than the method of aligning, inserting and tightening the screw, which is very suitable for scenarios that require frequent assembly and disassembly of the drive device 5. Embedding the drive device 5 into the assembly cavity 442 makes it more integrated with the device body and the overall structure more compact, which may help reduce the occupation of external space.

[0054] Furthermore, the upper plate 2 is located above the support 1, and the adjusting block 3 is movably disposed between the upper plate 2 and the support 1. Two adjusting blocks 3 are symmetrically distributed, and a pressure sensor 9 is provided between the opposite end faces of the two adjusting blocks 3. The bottom surface of the upper plate 2 is provided with a guide groove 7, and the top surface of the adjusting block 3 is provided with a guide block 6 that is adapted to the guide groove 7. The guide block 6 is inserted into the guide groove 7 along the length direction of the adjusting block 3.

[0055] Specifically, such as Figure 2 As shown, from top to bottom, the structure consists of an upper plate 2, two adjusting blocks 3, and a support 1. The adjusting blocks 3 are movable and located between the upper plate 2 and the support 1. Figure 3 As shown, the guide groove 7 is located on the bottom surface of the upper plate 2, as... Figure 5As shown, the guide block 6 is located on the top surface of the adjusting block 3 and is adapted to the guide groove 7. The guide block 6 is inserted into the guide groove 7. The two work together to ensure that the adjusting block 3 can only slide horizontally along its length direction and will not deviate or twist in other directions. The pressure sensor 9 is set between the opposite end faces of the two adjusting blocks 3 to sense the horizontal force (compression force) exerted on it by the two adjusting blocks 3. Combined with the mechanical balance relationship between the reaction force of the device body and the compression force between the two adjusting blocks 3, the reaction force of the device can be monitored. The pressure sensor 9 communicates with the external acquisition module, transmission module and detection module.

[0056] Working principle: When an adjustment is needed, the drive unit 5 pushes the two adjusting blocks 3, causing them to move towards each other (simultaneously towards the center) or away from each other (simultaneously to the sides). Since the top surface of the adjusting blocks 3 is inclined, and the guide block 6 is restricted to sliding within the guide groove 7 of the upper plate 2, the horizontal movement of the adjusting blocks 3 is forced to be converted into the vertical movement of the upper plate 2. When they move towards each other, the upper plate 2 rises; when they move away from each other, the upper plate 2 falls. Throughout the adjustment process, the upper load is always present, and the pressure sensor 9 is always working, which can monitor the changes in load in real time to ensure the safety and accuracy of the adjustment process.

[0057] Furthermore, the top surface of the adjusting block 3 is in contact with the bottom surface of the upper plate 2 by an inclined surface or a curved surface, and the bottom surface of the adjusting block 3 is in contact with the top surface of the support 1 by an inclined surface, a curved surface, or a plane. Alternatively, the top surface of the adjusting block 3 may be in planar contact with the bottom surface of the upper plate 2, while the bottom surface of the adjusting block 3 may be in inclined or curved contact with the top surface of the support 1.

[0058] Specifically, such as Figure 2 As shown, in this embodiment, the top surface of the adjusting block 3 is in inclined contact with the bottom surface of the upper plate 2, and the bottom surface of the adjusting block 3 is in planar contact with the top surface of the support 1. The bottom surface of the upper plate 2 forms an inverted V-shaped inclined surface. The pressure sensor 9 is pressed between the two adjusting blocks 3. The top surface of the adjusting block 3 is in inclined contact with the bottom surface of the upper plate 2. In the static load-bearing state, the upper load is converted into a horizontal component through the wedge-shaped adjusting block 3 and acts on the pressure sensor 9. Thus, the pressure sensor 9 can indirectly measure the total pressure borne by the support.

[0059] When the drive device 5 operates, it pushes the two adjusting blocks 3 to move towards each other in the horizontal direction (towards the center). Since the top of the adjusting blocks 3 is inclined, they are pushed towards the center, thereby reducing the height of the support. When the drive device 5 operates in the opposite direction, it causes the two adjusting blocks 3 to move away from each other in the horizontal direction (separating to both sides), and the height of the upper plate 2 rises.

[0060] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
