Description

[0001] The present application relates to the technical field of nuclear power plant construction surveying, in particular to a universal rotating cassette instrument operation platform and a use method thereof. BACKGROUND

[0002] The third generation nuclear reactor containment is a double-layer design circular structure, the inner and outer shell bodies have a narrow cross-sectional size, and the shell body is surrounded by a walking hanger platform. There is no hard support platform between the inner and outer shells during the construction period. The nuclear island peripheral building is a cast-in-place wall plate structure, and the floor slab support is a full-frame scaffold wood formwork support. Before the floor slab concrete is poured, there is also no hard and reliable support platform for high-sensitivity high-precision measuring instruments. In the complex room environment, the instruments are difficult to carry and move flexibly, and the construction efficiency is low.

[0003] Method one: the instruments can only be erected on the concrete surface in the steel reinforced wall of each floor by using a wooden measuring tripod. The vertical steel bars of the double-shell body and the wall of each floor are densely bound, the measuring line of sight is seriously blocked, and the measuring operation needs to be completed by turning around, which is low in construction efficiency and easy to cause measurement error accumulation and lead to uncontrollable measurement results.

[0004] Method two: a special measuring inner and outer steel pipe scaffold is erected, and then a wooden tripod is used to erect the instrument. This method is suitable for low floor height and has a part for erecting a special measuring scaffold. This method is limited by the stability of the inner measuring scaffold, has a certain influence on the quality control of high-precision measurement, has high construction cost and low construction efficiency, and needs to reserve a certain time for erecting a special measuring scaffold, which affects the construction progress.

[0005] Method three: a wooden tripod is used to erect the measuring instrument by connecting the steel pipe and the wall steel bar. This method is relatively simple and effective compared with the above two methods, but it is limited by the instrument erected at the root of the wall, the measuring field of view is limited, and it has similar shortcomings as method one. In addition, the steel pipe has elasticity and poor stability, which easily leads to uncontrollable measurement precision and other quality problems.

[0006] The above three methods all use wooden measuring tripods for instrument erection. The wooden tripod is heavy and not easy to transport on the construction site, and the procurement cost of the wooden tripod is relatively high, which limits its use in the nuclear power construction process.

[0048] Embodiment 1

[0049] Please refer to Figures 1-5 The universal rotating cassette instrument operation platform provided in the embodiments of the present application comprises a connecting rod 1, a tray 2, a first connecting piece 3 and a second connecting piece 4, wherein the tray 2 is connected to one end of the connecting rod 1 to place a measuring instrument 7; the first connecting piece 3 is connected to the other end of the connecting rod 1, and the circumferential angle of the first connecting piece 3 relative to the axial direction of the connecting rod 1 is adjustable; the second connecting piece 4 is connected to an attachment member, the second connecting piece 4 is rotationally connected to the first connecting piece 3, and the rotation center is perpendicular to the axial direction of the connecting rod 1.

[0050] The tray 2 is the mounting platform of the measuring instrument 7 and plays a bearing role. The connecting rod 1 is used to connect the tray 2 and the first connecting piece 3, and the length is preferably between 20 cm and 50 cm, and should not be too long or too short. The attachment member can be a fixed object on the site to be measured, which can include but is not limited to steel pipes, steel beams, wooden bars, steel bars, equipment, etc. Regardless of the position and direction of the second connecting piece 4, the direction of the tray 2 can be adjusted by rotating the connecting rod 1 and the first connecting piece 3, so that the tray 2 is upward.

[0051] Since the connecting rod can rotate around the first connecting member, and the first connecting member can rotate around the second connecting member, after the second connecting member is connected to the attachment member, the orientation of the connecting rod and the orientation of the tray surface can be easily adjusted. This operating platform has a simple structure, is easy to carry and highly flexible, is easy to install and use, and is highly adaptable to complex environments. While ensuring measurement accuracy, it facilitates the improvement of construction efficiency and the control of construction costs.

[0052] According to some embodiments of this application, a fixing clip 5 is provided on one side of the tray 2, and the fixing clip 5 is used to clamp the connecting rod 1. The fixing clip can realize the fixed connection between the tray and the connecting rod. Specifically, the fixing clip 5 may include a first clamping piece 51 and a second clamping piece 52 arranged opposite to each other. The first clamping piece 51 and the second clamping piece 52 have arc-shaped surfaces adapted to the outer wall of the connecting rod 1, and the two ends of the first clamping piece 51 and the second clamping piece 52 are connected by bolts. In use, the connecting rod is inserted between the arc-shaped surfaces of the first clamping piece and the second clamping piece, and the first clamping piece and the second clamping piece move relative to each other by tightening the bolts, thereby realizing that the first clamping piece and the second clamping piece hug the outer circle of the connecting rod.

[0053] According to some embodiments of this application, a fastener 6 protrudes from the other side of the tray 2. The fastener 6 is used to fix the measuring instrument 7 to the tray 2. By setting the fastener, it can cooperate with the base of the measuring instrument to achieve a fixed connection between the measuring instrument and the tray. Specifically, the first clamping piece 51 on the fixing clamp 5 that contacts the tray 2 is provided with a clamping piece boss 511. A threaded hole is provided on the clamping piece boss 511, and a through hole is provided in the center of the tray 2. The fastener 6 includes a first threaded section 61 and a second threaded section 62. The first threaded section 61 is used to connect with the threaded hole on the clamping piece boss 511, and the second threaded section 62 is used to connect with the threaded hole on the base of the measuring instrument 7. The diameter of the first threaded section 61 is smaller than the diameter of the second threaded section 62, so that a transition step surface is formed between the first threaded section 61 and the second threaded section 62. When the first threaded section 61 is passed through the through hole in the center of the tray 2 and screwed into the threaded hole on the clamping piece boss 511 during assembly, the tray 2 can be pressed onto the fixing clamp 5 through the transition step surface. Meanwhile, the first threaded section 61 and the second threaded section 62 have the same direction of rotation to prevent the first threaded section from becoming loose when the threaded hole on the base of the measuring instrument is screwed onto the second threaded section. To facilitate the first threaded section being screwed into the threaded hole on the clamping boss, an internal hexagonal socket is provided at the end of the second threaded section, so that an internal hexagonal wrench can be used to turn the fastener.

[0054] According to some embodiments of this application, the first connecting member 3 includes a connecting block 31 and a locking knob. The connecting block 31 has a mounting hole adapted to the connecting rod 1. The locking knob is connected to the connecting block 31 to restrict the circumferential rotation of the connecting block 31 relative to the connecting rod 1. Specifically, a slit 311 is formed on the side wall of the connecting block 31. The slit 311 extends along the axial direction of the connecting rod 1 and communicates with the mounting hole. When the locking knob is screwed in, it causes relative deformation on both sides of the slit 311 to clamp the connecting rod 1, so that the connecting rod cannot rotate or move axially, thereby locking the relative position of the connecting block and the connecting rod. For example, the connecting block 31 is cylindrical, the axis of the mounting hole is perpendicular to the axis of the connecting block 31, and the axis of the mounting hole is located on one side of the axis of the connecting block 31, that is, the two are offset. The slit 311 on the connecting block 31 must extend at least beyond the center hole of the connecting block so that when the locking knob is applied, sufficient deformation can be generated on both sides of the slit to clamp the connecting rod. Of course, it can be understood that the slit 311 can also run through the entire connecting block 31 laterally, that is, the connecting block 31 is divided into upper and lower parts along the axial direction by the slit 311.

[0055] According to some embodiments of this application, the second connector 4 includes a clamping portion for connecting to the attachment member, wherein the clamping portion has a cylindrical connecting disk 41 on the side opposite to the connecting block 31, and the connecting disk 41 is rotatable relative to the connecting block 31.

[0056] According to some embodiments of this application, the locking knob is connected to the connecting disc 41 to restrict the circumferential rotation of the connecting disc 41 relative to the connecting block 31. Specifically, the locking knob may include a locking rod 32 and a locking cap 33. One end of the locking rod 32 is fixedly connected to the center of the connecting disc 41, and the other end of the locking rod 32 passes through the central hole of the connecting block 31 and is threadedly connected to the locking cap 33. In use, by screwing in the locking cap, on the one hand, deformation can be generated on both sides of the cut of the connecting block to clamp the connecting rod, thereby restricting the movement of the connecting rod; on the other hand, the connecting disc and the connecting block can be pressed together, thereby restricting the rotation of the connecting block.

[0057] According to some embodiments of this application, a toothed engagement structure is provided between the contact surfaces of the connecting disc 41 and the connecting block 31. This design increases the friction between the two and can prevent the connecting block from rotating after being fixed in a fixed direction.

[0058] According to some embodiments of this application, the clamping part includes a clamping body 42 and a push rod 43. The clamping body 42 has an opening 421 for accommodating an attachment member. The push rod 43 is disposed on the clamping body 42, and the length of the push rod 43 extending into the opening 421 is adjustable. This design allows the attachment member to be pressed against the inner wall of the opening by extending the push rod after entering the opening, thereby achieving a fixed connection between the clamping body and the attachment member. Specifically, the clamping body 42 is generally U-shaped, and the outer wall opposite to the opening 421 is fixedly connected to the connecting plate 41. The push rod 43 is disposed on either side of the opening 421 of the clamping body 42, and the push rod 43 forms a threaded engagement with the clamping body 42, so that its length extending into the opening 421 can be adjusted by rotating the push rod 43.

[0059] According to some embodiments of this application, a pressure block 44 is provided at one end of the top rod 43 located within the opening 421. The pressure block 44 is used to contact the attachment member to achieve clamping. This arrangement allows for increasing the contact area with the attachment member by changing the size of the pressure block, resulting in a more stable connection between the clamping body and the attachment member. To facilitate rotation of the top rod 43, the top rod 43 and the pressure block 44 can be rotatably connected. This ensures that when the attachment member enters the opening, the pressure block will not rotate when in contact with the attachment member; that is, the pressure block will not rotate with the rotation of the top rod. For a more reliable connection with the attachment member, V-shaped grooves are provided on the surfaces of the pressure block and the clamping body that contact the attachment member.

[0060] Many components of this operating platform can be manufactured using lightweight, high-strength aluminum alloy, ensuring a light overall weight and easy portability. The connecting rod is cylindrical and can be made from lightweight, high-strength aluminum alloy tubing. To prevent resonance, it can also be made from sturdy yet lightweight wood. Fasteners can connect the tray to the clamps and also match the bolt holes on the measuring instrument's base. This operating platform makes it easier to set up instruments in various environments, such as before pouring concrete floor slabs in construction plants, and in confined spaces with complex conditions. It is applicable to a wider range of construction environments, improves construction efficiency, and ensures construction quality. The lightweight materials make it easy for personnel to carry, and its manufacturing cost is lower than that of wooden tripods.

[0061] Compared with the prior art, the universal rotating cassette instrument operating platform in this application embodiment has at least the following advantages and beneficial effects: 1. It is not only suitable for conventional environments with stable and reliable positions for setting up measuring instruments, but also for special environments without stable and reliable positions for setting up measuring instruments, as well as for complex and confined spaces, making it more widely applicable than wooden measuring tripods; 2. It is made of lightweight and high-strength alloy materials, is detachable and combinable, and is convenient and flexible to use. Compared with wooden measuring tripods, it is lighter and easier to carry, and its operation methods are more flexible and varied; 3. It has a wider range of application scenarios and improves the efficiency of measurement construction; 4. It solves the technical problem of setting up internal and external measuring frames and measuring support frames required in the special environment of nuclear power plant construction, while also saving construction costs; 5. It can be mass-produced, avoiding excessive purchases of wooden measuring tripods, saving procurement costs, and has a longer service life than wooden measuring tripods.

[0062] Example 2

[0063] The method of using a universal rotary cassette instrument operating platform provided in this application embodiment includes the following steps:

[0064] Step 1: Connect both ends of the connecting rod 1 to the tray 2 and the first connecting member 3. Specifically, connect one end of the connecting rod 1 to the fixing clamp 5, and connect the tray 2 to the fixing clamp 5 through the fastener 6.

[0065] Step 2: Connect the second connector 4 to the attachment member, specifically by clamping the clamping body 42 onto the attachment member and extending the top rod 43 by rotating it to press the attachment member tightly.

[0066] Step 3: Loosen the locking cap 33, rotate the first connecting piece 3 and the connecting rod 1 so that the connecting rod 1 faces the measurement direction and the tray 2 faces upward. After adjustment, lock the positions of the first connecting piece 3 and the connecting rod 1 by using the locking cap 33.

[0067] Step 4: Install the base of the measuring instrument 7 onto the tray 2 using fastener 6, and level the measuring instrument using the leveling screws provided on the measuring instrument.

[0068] The operating platform is fixed to the attached structure (such as steel pipe, steel beam, timber, 40mm rebar, equipment, etc.) of the construction site using the second connector. Loosen the locking knob, rotate the connecting rod and the first connector according to the orientation of the tray until the tray surface is facing upwards, tighten the locking knob, and set the measuring instrument on the tray using fasteners. Adjust the instrument status using the instrument screws to proceed to the next measurement operation.

[0069] This operating platform has a simple structure, is lightweight and flexible, easy to carry and use, and has a wider range of applications. It not only solves the drawbacks of not having a stable and reliable platform and setting up instruments in confined spaces during nuclear power plant construction, but is also suitable for conventional construction environments, improving construction efficiency and saving the cost of other measures required due to the lack of a stable and reliable platform. At the same time, the application of this operating platform also makes the measurement methods more flexible.
