Description

Technical Field

[0001] This utility model relates to the field of engineering measurement technology, specifically to an installation accessory for a photoelectric deflectometer. Background Technology

[0002] In modern engineering, photoelectric deflectometers, as an advanced measuring tool, play an important role in the health monitoring of structures such as bridges and buildings. However, despite the high precision and sensitivity of photoelectric deflectometers, there are many problems in their installation process and auxiliary devices, which seriously restrict their practical application.

[0003] The installation of existing photoelectric deflectometers typically requires complex fixing steps, such as using bolts, nuts, and other fasteners to secure the equipment to bridges or building structures. This method is not only time-consuming but also demands high technical skills from construction personnel, especially when installing at heights or in confined spaces, significantly increasing the operational difficulty. Furthermore, existing auxiliary materials lack flexible adjustment capabilities to achieve multi-directional adjustment (left, right, up, and down). Moreover, with technological advancements, the lens of the photoelectric deflectometer is susceptible to external light source influences, which can interfere with the accuracy of monitoring data. Therefore, we need to propose an installation auxiliary material for photoelectric deflectometers. Utility Model Content

[0004] The purpose of this invention is to provide an installation accessory for a photoelectric deflectometer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An installation accessory for a photoelectric deflectometer includes a base, a welded universal joint, a first flat-head screw, a second flat-head screw, a fixing component, a photoelectric deflectometer, a protective cover, and a second countersunk screw. The welded universal joint consists of a base plate and a U-shaped frame. The base plate is mounted on top of the base using the first flat-head screw, and the U-shaped frame is welded to the base plate. The horizontal rotation angle can be adjusted by adjusting the tightness of the first flat-head screw. The fixing component is mounted on the U-shaped frame of the welded universal joint using the second flat-head screw. The vertical pitch angle can be adjusted by adjusting the tightness of the second flat-head screw. The photoelectric deflectometer is mounted on the fixing component, and the protective cover is fixed to a pre-drilled hole on the outer shell of the photoelectric deflectometer using the second countersunk screw.

[0007] Preferably, the fixing assembly includes a movable bracket, a support plate, a first countersunk screw, and a third flat round head screw. The support plate is horizontally fixed to the top of the movable bracket by the first countersunk screw. The movable bracket is installed on the two side walls of the U-shaped frame by the second flat round head screw. The support plate is fixedly installed to the bottom of the photoelectric deflectometer by the third flat round head screw, and is used to support the photoelectric deflectometer.

[0008] Preferably, the base is welded together from an assembly plate, a support tube, and an mounting plate, and the assembly plate has several elongated assembly slots for fixing expansion bolts to the concrete structure, and the assembly plate can be directly welded to the steel structure.

[0009] Preferably, nuts compatible with flat round head screws are welded to the bottom of the mounting plate, the inner side wall of the U-shaped frame, and the inner top of the movable bracket, and through holes corresponding to the nuts are opened on the mounting plate, the U-shaped frame, and the movable bracket.

[0010] Preferably, the base plate has several sets of first arc-shaped grooves arranged in a ring array for assembly and fixation of first flat round head screws. The first arc-shaped grooves allow the base plate to rotate within the ring range by the screws, thereby realizing the horizontal rotation adjustment of the welding universal joint.

[0011] Preferably, a shock-absorbing pad is attached to the top of the mounting plate, and the top of the shock-absorbing pad is attached to the bottom of the base plate.

[0012] Preferably, the first flat head screw, the second flat head screw, and the third flat head screw are all configured as internal hexagonal flat head screws, and the first countersunk screw and the second countersunk screw are both configured as Phillips head countersunk screws.

[0013] Preferably, a second arc-shaped groove is provided on both sides of the bottom of the movable bracket. The second arc-shaped groove allows the second flat round head screw to slide in the groove. The pitch angle of the movable bracket can be changed by adjusting the tightness of the screw.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Compared with the traditional bolt and nut combination installation method, the fixing method using screws and welded nuts is simpler to operate. It only requires connecting by fixing screws, which greatly reduces the difficulty of on-site installation. Especially in complex installation locations such as high-altitude operations or confined spaces, it significantly reduces the operation steps and the technical requirements for construction personnel, and improves installation efficiency.

[0016] 2. By adding vibration damping pads to the bottom of the welded universal joint, the vibration transmitted to the ground or other structures during equipment operation can be reduced. In addition, the vibration damping pads can also be used to fix the equipment and prevent it from moving during vibration.

[0017] 3. Existing installation accessories only have vertical adjustment function, which is difficult to meet the flexible adjustment requirements in the horizontal direction. Therefore, a fixing component is added to the base to enable the installation accessories to have flexible adjustment capabilities in both the horizontal and vertical directions, so as to enhance the overall adjustment flexibility and adaptability.

[0018] 4. By adopting a modular design concept, the support plate of this installation accessory is the only component that needs to be replaced according to the model of the photoelectric deflectometer or the application scenario, while all other parts can maintain universality and interchangeability. This design not only simplifies the product upgrade and maintenance process, but also significantly reduces the incompatibility problem of accessories caused by product updates, and improves the flexibility and adaptability of the overall system.

[0019] 5. A specific protective cover is provided outside the photoelectric deflectometer to prevent interference from external light sources. It also provides sufficient protection against external factors such as dust, moisture, and impacts, thus extending the service life of the equipment. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides a technical solution:

[0028] An installation accessory for a photoelectric deflectometer includes a base 1, a welded universal joint 2, a first flat head screw 5, a second flat head screw 6, a fixing component, a photoelectric deflectometer 9, a protective cover 10, and a second countersunk screw 12. The welded universal joint 2 consists of a base plate 201 and a U-shaped frame 202. The base plate 201 is mounted on the top of the base 1 by the first flat head screw 5. The U-shaped frame 202 is welded to the base plate 201. The horizontal rotation angle can be adjusted by adjusting the tightness of the first flat head screw 5. The fixing component is mounted on the U-shaped frame 202 of the welded universal joint 2 by the second flat head screw 6. The vertical pitch angle can be adjusted by adjusting the tightness of the second flat head screw 6. The photoelectric deflectometer 9 is mounted on the fixing component. The protective cover 10 is fixed to the pre-set screw hole on the outer shell of the photoelectric deflectometer 9 by the second countersunk screw 12.

[0029] In an optional embodiment: the fixing assembly includes a movable bracket 3, a support plate 4, a first countersunk screw 7 and a third flat round head screw 8. The support plate 4 is horizontally fixed to the top of the movable bracket by the first countersunk screw 7. The movable bracket 3 is installed on the two side walls of the U-shaped frame 202 by the second flat round head screw 6. The support plate 4 is fixedly installed to the bottom of the photoelectric deflectometer 9 by the third flat round head screw 8 for supporting the photoelectric deflectometer 9.

[0030] It should be noted that the movable bracket 3 is made of high-quality aluminum alloy and is precision machined, featuring light weight and high strength. The surface of the support plate 4 is anodized, which not only enhances its appearance but also improves its wear resistance and corrosion resistance. The first countersunk screw 7 firmly fixes the support plate 4 to the top of the movable bracket 3, ensuring the horizontality of the support plate 4 and providing a stable mounting surface for the photoelectric deflector 9. The third flat round head screw 8 is also made of high-strength material and is tightened to the specified torque during installation, ensuring a tight fit between the photoelectric deflector 9 and the support plate 4 and preventing shaking during measurement. The connection method between the movable bracket 3 and the U-shaped frame 202 ensures that the movable bracket 3 maintains good stability during angle adjustment, without loosening or shifting.

[0031] The fixed assembly has a reasonable structural design and the connection between the components is solid, which can reliably support the photoelectric deflectometer 9. At the same time, its adjustable angle function further improves the convenience of installation and the accuracy of measurement.

[0032] In an optional embodiment: the base 1 is welded together from an assembly plate 101, a support tube 102 and an mounting plate 103, and the assembly plate 101 has several elongated assembly slots for fixing expansion bolts to the concrete structure, and the assembly plate 101 can be directly welded to the steel structure.

[0033] It should be noted that the mounting plate 101, support tube 102, and mounting plate 103 of the base 1 are all made of high-strength steel. The welding process strictly follows the welding process specifications to ensure welding quality. The design of the long strip mounting groove is highly practical. When fixed to the concrete structure, the expansion bolts can be adjusted within a certain range after passing through the mounting groove, which facilitates construction and installation. When it is necessary to connect to the steel structure, the mounting plate 101 can be directly fixed by welding, which reduces the use of additional connecting parts and improves connection efficiency and stability. The support tube 102 plays a supporting and reinforcing role to ensure that the base 1 remains stable when bearing the photoelectric deflector 9 and other components, and will not deform or tilt.

[0034] The diverse fixing methods of base 1 enable it to adapt to different installation environments, achieving reliable fixing whether it is a concrete structure or a steel structure; the long strip assembly groove and reasonable welding structure design enhance the flexibility and stability of installation.

[0035] In an optional embodiment: nuts 13 adapted to flat round head screws are welded to the bottom of the mounting plate 103, the inner side wall of the U-shaped frame 202, and the inner top of the movable bracket 3, and through holes corresponding to the nuts 13 are opened on the mounting plate 103, the U-shaped frame 202, and the movable bracket 3.

[0036] It should be noted that the nut 13 is made of high-strength steel of the same material as all the components and is firmly fixed to the mounting plate 103, U-shaped frame 202 and movable bracket 3 by welding. This welded nut design has higher strength and better wear resistance compared to tapping directly on the components. When installing flat round head screws, the nut 13 can provide a reliable threaded connection to prevent the screws from loosening. The dimensional accuracy of the through hole is strictly controlled to ensure that the flat round head screws can pass through smoothly and fit precisely with the nut 13. At the same time, this design facilitates disassembly and maintenance. When it is necessary to inspect or replace the components, it can be easily disassembled by simply unscrewing the screws.

[0037] The design of welded nuts and through holes improves the reliability and stability of the connections between components and enhances the strength of the overall structure; its ease of disassembly and maintenance reduces the difficulty and cost of later maintenance of the equipment.

[0038] In an optional embodiment: the base plate 201 has several sets of first arc-shaped grooves arranged in a ring array for the first flat round head screws 5 to be assembled and fixed. The first arc-shaped grooves allow the base plate 201 to rotate within the ring range by the screws, thereby realizing the horizontal rotation adjustment of the welding universal joint 2.

[0039] It should be noted that the design of the first arc-shaped groove is the core structure for achieving horizontal rotation adjustment of the welding universal joint 2. These arc-shaped grooves are precision-machined with accurate curvature and dimensions, ensuring that the base plate 201 can move smoothly and stably during rotation. The number and distribution of each set of first arc-shaped grooves are rationally planned to evenly distribute the tightening force of the first flat round head screw 5, avoiding excessive local stress during rotation adjustment. In actual operation, after loosening the first flat round head screw 5, the base plate 201 can be precisely adjusted within the annular range according to measurement requirements. After adjustment, tightening the screw will fix the base plate 201 at the required angle, ensuring the horizontal stability of the welding universal joint 2. The design of the first arc-shaped groove makes the horizontal rotation adjustment of the welding universal joint 2 more flexible and precise, meeting the angle adjustment needs of different measurement scenarios and improving the applicability of the photoelectric deflectometer installation accessories.

[0040] In an optional embodiment: a shock-absorbing pad 11 is attached to the top of the mounting plate 103, and the top of the shock-absorbing pad 11 is attached to the bottom of the base plate 201.

[0041] It should be noted that the shock-absorbing pad 11 is usually made of highly elastic rubber material, which has good shock absorption and buffering performance. Its surface is specially treated so that it can fit tightly with the mounting plate 103 and the base plate 201 and is not easy to fall off. In practical applications, when there is vibration in the surrounding environment, the shock-absorbing pad 11 can effectively absorb and buffer the vibration energy, reduce the impact of vibration on the photoelectric deflectometer 9, and avoid measurement errors caused by vibration.

[0042] In an optional embodiment: the first flat head screw 5, the second flat head screw 6 and the third flat head screw 8 are all configured as internal hexagonal flat head screws, and the first countersunk screw 7 and the second countersunk screw 12 are both configured as cross-head countersunk screws.

[0043] It should be noted that hex socket head cap screws are characterized by their compact structure and high strength. The hex socket design allows for the application of greater torque when tightened with a special wrench, ensuring a secure connection. During installation, the flat, rounded head of the hex socket head cap screw fits tightly against the surface of the component, which is not only aesthetically pleasing but also prevents scratches to operators and other parts. Phillips head countersunk screws, on the other hand, offer advantages such as easy installation and lower cost. They can be installed and removed using a standard Phillips screwdriver. In the installation accessories for photoelectric deflectometers, the selection of different screw types is determined based on the connection requirements and usage scenarios of each component, ensuring both connection reliability and ease of installation while controlling costs. The rational selection of different screw types fully leverages their respective advantages, improves installation efficiency, ensures the firmness and stability of connections between components, and also considers cost factors, achieving an optimal balance between performance and cost.

[0044] In an optional embodiment: a second arc-shaped groove is provided on both sides of the bottom of the movable bracket 3. The second arc-shaped groove allows the second flat round head screw 6 to slide in the groove. The pitch angle of the movable bracket 3 can be changed by adjusting the tightness of the screw.

[0045] It should be noted that the second arc-shaped groove is similar to the first arc-shaped groove, also finely machined, with precise dimensions and shape. The depth and width of the second arc-shaped groove are strictly calculated to ensure that the second flat round head screw 6 can slide freely within the groove, enabling the pitch angle adjustment of the movable bracket 3, while also providing sufficient friction after the screw is tightened to prevent the movable bracket 3 from shifting its angle during measurement. In actual operation, the operator can loosen the second flat round head screw 6 according to the measurement requirements, adjust the movable bracket 3 to a suitable pitch angle, and then tighten the screw to fix it. This design makes the angle adjustment of the movable bracket 3 more convenient and quick, and can quickly adapt to different measurement environments and requirements.

[0046] Working principle: In use, the mounting plate 101 of the base 1 is fixed to the concrete structure by expansion bolts or directly welded to the steel structure. The top of the mounting plate 103 is attached to the shock-absorbing pad 11, which is attached to the bottom of the base plate 201 to provide shock absorption. The base plate 201 is installed on the top of the base 1 by the first flat round head screw 5 passing through the first arc-shaped groove of the annular array on it. The U-shaped frame 202 is welded to the base plate 201. By adjusting the tightness of the first flat round head screw 5, the base plate 201 can be rotated within the annular range by the first arc-shaped groove, thereby adjusting the horizontal left and right rotation angle of the welded universal joint 2. The movable bracket 3 is installed on the side walls of the U-shaped frame 202 by the second flat round head screw 6. The second arc-shaped groove opened at the bottom of both sides of the movable bracket 3 allows the movable bracket 3 to move on the U-shaped frame 202. Adjusting the tightness of the second flat round head screw 6 can change the pitch angle of the movable bracket 3, thereby realizing the adjustment of the pitch angle of the fixed component and the photoelectric deflector 9.

[0047] The support plate 4 is horizontally fixed to the top of the movable bracket 3 by the first countersunk screw 7. The photoelectric deflectometer 9 is installed on the support plate 4 by the third flat round head screw 8. The protective cover 10 is fixed to the preset screw hole of the outer shell of the photoelectric deflectometer 9 by the second countersunk screw 12, which plays a protective role for the photoelectric deflectometer 9.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
