Description

Technical Field

[0001] The invention relates to the technical field of steel structure installation, and in particular to a dynamic measuring tool for high-altitude sliding deviation of a large-span steel structure. Background Art

[0002] The dynamic measurement tool for the high-altitude sliding deviation of large-span steel structures is mainly used in the high-altitude sliding construction process of large-span steel structures. It is very important to accurately control the position and posture of the structure. The dynamic measurement tool can monitor the deviation in the sliding process in real time, find problems in time and take adjustment measures to ensure that the steel structure is finally accurately in place and meets the accuracy required by the design. However, there are certain risks in the high-altitude sliding construction of large-span steel structures, such as structural instability and collision. Therefore, the dynamic measurement tool can monitor the movement state of the structure in real time, warn of potential dangers in advance, and provide construction personnel with enough time to take safety measures and reduce construction risks.

[0003] In high temperature environments, the electronic components of the sensor may be affected, resulting in increased measurement errors. At the same time, in windy weather, the shaking of the structure may affect the sensor's measurement results.

[0004] In the patent document with the publication number CN110672002A, a dynamic measurement tool for high-altitude slip deviation of large-span steel structure is disclosed, which includes a measurement frame fixed on the large-span steel structure, a coordinate plate fixed on the upper surface of the slip beam, and an external mobile terminal. The measurement frame is composed of a support rod and a probe, the coordinate plate includes a shell, a piezoelectric generator, a wireless transmitter and a battery, and the mobile terminal is composed of a wireless receiver and a laptop computer connected together. This solves the problem of inconvenient operation and inability to ensure accuracy in measuring slip deviation.

[0005] When the above device is in use, it utilizes the contact between the probe and the coordinate plate to detect the pressure change between the two, and then understands the movement deviation of the large-span steel structure when sliding at high altitude. The probe at high altitude is easily affected by wind force. The wind pressure causes the probe to have certain pressure data. Then, when it performs pressure detection with the coordinate plate, the data will have a large error.

[0022] 2.

When the cleaning bristles and the inclined connecting block are in close contact with the garbage or snow, the friction between the two is relatively large, and the corresponding plug-in block has a certain degree of torsion along the surface of the electric telescopic rod. As the cleaning bristles and the inclined connecting block follow the probe away from the coordinate plate, the torsion restores the inclined connecting block and the cleaning bristles to their original positions. At this time, the garbage or snow adsorbed by the cleaning bristles and the inclined connecting block is shaken off to avoid affecting the later cleaning.

[0023] 3. If the large-span steel structure shakes violently when sliding at high altitude, it means that the weather is bad and not suitable for high-altitude work, and the installation of the large-span steel structure and the metering support assembly is unstable, causing the auxiliary clamping block connected by the rope to slide along the vertical connecting frame plate, and the pressure corresponding to the auxiliary clamping block on the pressure detection rod changes. Then the staff can quickly understand the operating status of the large-span steel structure through the terminal, thereby improving the stability of the large-span steel structure and the device running together and avoiding accidents during the operation of the large-span steel structure.

DETAILED DESCRIPTION

[0036] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0037] like Figure 1 As shown, the present invention proposes a dynamic metering tool for high-altitude sliding deviation of large-span steel structures, including a metering support assembly 1, a connecting assembly 3 is installed on one side of the metering support assembly 1, a metering assembly 4 is installed on the other side of the metering support assembly 1, a cleaning assembly 5 is rotatably installed on the outside of the metering assembly 4 through a connecting rod, a coordinate plate 2 is arranged at the bottom of the cleaning assembly 5 and the metering assembly 4, the metering support assembly 1 is installed on the large-span steel structure, and the coordinate plate 2 is installed on the sliding beam, and the electrical signal generated between the metering assembly 4 and the coordinate plate 2 during movement is transmitted to the terminal, and then the sliding trajectory of the large-span steel structure is depicted in a multi-point line manner, and the forward distance and angle deviation of the large-span steel structure during sliding are given and recorded.

[0038] like Figure 8-Figure 11As shown, the connection assembly 3 includes a vertical connection frame plate 301 fixedly mounted on the side of the metering support assembly 1 away from the motor assembly 401, two auxiliary clamping blocks 304 are slidably mounted inside the vertical connection frame plate 301, and a folding frame 303 is hinged inside the two auxiliary clamping blocks 304, and a pressure detection rod 308 is fixedly mounted between the auxiliary clamping blocks 304 and the vertical connection frame plate 301. The connection assembly 3 also includes sliding support plates 305 fixedly mounted on both sides of the metering support assembly 1, and two sliding blocks are hinged on both sides of the folding frame 303 307, and the two sliding blocks 307 are slidably installed inside the corresponding sliding support plate 305, the internal threads of the two sliding blocks 307 are installed with positive and negative threaded rods 306, the auxiliary clamping block 304 is fixedly installed with a sling rope 302 inside, and the side of the sling rope 302 away from the auxiliary clamping block 304 is installed on the motor assembly 401, corresponding to the lifting position of the large-span steel structure, the staff manually rotates the positive and negative threaded rods 306, and the threads connecting the positive and negative threaded rods 306 and the two sliding blocks 307 are opposite threads, then the two sliding blocks 307 moves in the opposite direction. According to the installation position of the lifting hook of the large-span steel structure, the folding frame 303 folds or opens. The folding frame 303 drives the two auxiliary clamping blocks 304 to move to the specified lifting position, and the rope is fixedly installed inside the auxiliary clamping block 304. One side of the rope is installed on the large-span steel structure, and the other side passes through the auxiliary clamping block 304 and is located at the upper and lower sides of the motor assembly 401. The two ropes are symmetrically arranged about the horizontal center line of the sling rope 302. If the large-span steel structure slides at high altitude If there is a violent shaking during the shift, it means that the weather is bad and not suitable for high-altitude work, and the installation of the large-span steel structure and the metering support assembly 1 is unstable, causing the auxiliary clamping block 304 connected by the rope to slide along the vertical connection frame plate 301, and the pressure corresponding to the auxiliary clamping block 304 on the pressure detection rod 308 changes, and then the staff quickly understands the operation status of the large-span steel structure through the terminal, thereby improving the stability of the large-span steel structure and the device running together and avoiding accidents during the operation of the large-span steel structure;

[0039] A positioning slider 309 is fixedly installed on one side of the sliding support plate 305 away from the folding frame 303. Two glued mounting blocks 311 are slidably installed inside the positioning slider 309. One side of the two glued mounting blocks 311 is hinged with an auxiliary mounting frame 310. The connecting component 3 is fixedly installed on one side of the large-span steel structure. First, according to the positioning position specified by the large-span steel structure, the corresponding mounting holes are aligned. If the mounting holes are in corresponding positions with the vertical center line of the positioning slider 309, the staff manually pulls the two auxiliary mounting frames 310 according to the height of the mounting holes. 10 is moved to the position of the mounting hole, and the bolt is passed through the auxiliary mounting frame 310 to cooperate with the mounting hole for positioning. At the same time, there is a limiting spring between the glued mounting block 311 and the positioning slider 309 to position the sliding distance of the glued mounting block 311. At the same time, after the auxiliary mounting frame 310 is positioned by the bolt, the tension of the spring makes the auxiliary mounting frame 310 more stable. If the position of the mounting hole deviates from the vertical center line of the positioning slider 309, the staff can deflect the auxiliary mounting frame 310 along the glued mounting block 311 to the specified position for bolt positioning.

[0040] like Figure 1-Figure 7 As shown, the metering component 4 includes a motor component 401 fixedly mounted on one side of the metering support component 1, the output shaft of the motor component 401 is fixedly mounted with a supporting gear block 402, the bottom of the supporting gear block 402 is fixedly mounted with a hollow fixed rod 409, the bottom of the supporting gear block 402 is fixedly mounted with a plurality of hollow fixed rods 409, and the plurality of hollow fixed rods 409 are arranged in an annular state around the surface of the supporting gear block 402, the interior of the hollow fixed rod 409 is slidably mounted with an insertion slider 412 through a positioning spring 415, and a probe 411 is fixedly mounted at the bottom of the insertion slider 412;

[0041] The outer side of the plug-in slider 412 is hinged with a first hinge rod 403 with the same number as the guard plate 410, and the side of the first hinge rod 403 away from the plug-in slider 412 is hinged with a second hinge rod 404, and the outer side of the second hinge rod 404 is fixedly installed with a first hollow shielding airbag 406, and the outer side of the pressing hinge rod 405 is fixedly installed with a second hollow shielding airbag 407, and the number of the first hinge rod 403 and the second hinge rod 404 is the same, and one side of the second hinge rod 404 is hinged to one side of the guard plate 410, and the outer side of the second hinge rod 404 is hinged with two third hinge rods 413, and the two third hinge rods 413 are hinged. There is a pressing hinge rod 405, and the arc surface at the bottom of the second hinge rod 404 is arranged in a fit state with the top arc surface of the pressing hinge rod 405, and a corresponding auxiliary spring 414 is fixedly installed at the connection between the third hinge rod 413 and the second hinge rod 404. When the probe 411 comes into contact with the coordinate plate 2, when the sliding beam and the coordinate plate 2 are in a normal horizontal state, the height of the probe 411 is consistent, and the pressing hinge rod 405 and the second hinge rod 404 are distributed on the surrounding side of the plug-in slider 412 to protect the probe 411 and reduce the interference of wind and dust on the measurement of the probe 411. The electric current generated between the coordinate plate 2 and the probe 411 The signal strength is equal, and the strength of the emitted electrical signal is also equal; when the sliding beam and the coordinate plate 2 are inclined, that is, there is an inclination, it is explained here that the inclination required by the building is small, and the probe 411 is extended and retracted along the inside of the hollow fixed rod 409 under the limit of the positioning spring 415 as the large-span steel structure slides through the plug-in slider 412, and the motor assembly 401 drives the hollow fixed rod 409 to rotate slowly. When the probe 411 can contact the coordinate plate 2, the hinge rod 405 can rotate and push a small amount of debris or snow on the surrounding side to the outside, reducing interference with the probe 411. At the same time, as the probe 411 moves upward, the first hinge rod 4 03 drives the second hinge rod 404 and the pressing hinge rod 405 to tilt downward along the guard plate 410, which is more closely attached to the surface of the coordinate plate 2, further preventing the wind from generating a greater lateral force on the tilted structure, and improving the accuracy of the contact detection between the probe 411 and the sliding beam and the coordinate plate 2 in the tilted state. The second hollow shielding airbag 407 drives the pressing hinge rod 405 to bend under the limit of the corresponding auxiliary spring 414 according to the inclination of the contact surface, so that the gap between the second hollow shielding airbag 407 and the coordinate plate 2 is smaller, and the first hollow shielding airbag 406 and the second hollow shielding airbag 407 can better prevent the interference of wind pressure;

[0042] A compression airbag block 408 is fixedly installed between the second hollow shielding airbag 407 and the first hollow shielding airbag 406, and a plurality of airbag ring blocks 416 are fixedly installed inside the first hollow shielding airbag 406. A bidirectional S-shaped elastic rope pad 417 is fixedly installed between every two airbag ring blocks 416, and one side of the bidirectional S-shaped elastic rope pad 417 is attached to the inner wall of one side of the first hollow shielding airbag 406, and the other side of the bidirectional S-shaped elastic rope pad 417 is attached to the inner wall of the other side of the first hollow shielding airbag 406. When wind blows into the first hollow shielding airbag 406, the elastic force of the airbag ring block 416 is used to buffer the external impact, thereby improving the first hollow shielding airbag 406's ability to block external influences. The bidirectional S-shaped elastic rope pad 417 uses its own elastic force to stabilize the multiple airbag ring blocks 416. At the same time, when the first hollow shielding airbag 406 is deformed while protecting the pressure on the outside of the first hollow shielding airbag 406 or the pressure inside the first hollow shielding airbag 406 and being affected by thermal expansion and contraction, the airbag ring block 416 and the air pressure inside the first hollow shielding airbag 406 change and deform. In this process, the bidirectional S-shaped elastic rope pad 417 is used to limit and restore the deformation direction of the outer wall and the inner wall of the first hollow shielding airbag 406, thereby reducing the influence of thermal expansion and contraction on the first hollow shielding airbag 406 and improving the stability of the first hollow shielding airbag 406 at different temperatures.

[0043] In this embodiment, Figure 1-Figure 6As shown, the cleaning assembly 5 includes a positioning slide cavity frame 501 rotatably mounted on the outside of the supporting gear block 402 through a connecting rod, an electric telescopic rod 504 is arranged inside the positioning slide cavity frame 501, a gear slider 502 is rotatably mounted on the bottom of the positioning slide cavity frame 501, a transmission chain 508 is installed between the gear slider 502 and the supporting gear block 402, a slide cavity is opened on the outside of the electric telescopic rod 504, the outside of the electric telescopic rod 504 is slidably mounted on the inside of the gear slider 502 through the slide cavity, a corresponding plug-in block 503 is slidably mounted on the bottom of the electric telescopic rod 504, and a plurality of inclined connecting blocks 503 are fixedly installed on the outside of the corresponding plug-in block 503. 07, and a plurality of inclined connecting blocks 507 are arranged in a ring state with respect to the surface of the corresponding plug-in block 503, a cleaning brush 506 is fixedly installed between every two inclined connecting blocks 507, and an auxiliary spring 505 is fixedly installed between the bottom of the corresponding plug-in block 503 and the bottom of the electric telescopic rod 504. Since the large-span steel structure is operated at high altitude, there are many stones in the surrounding buildings, and the stone foam is easy to fly in the air, which in turn causes great interference to the press-sensitive surface on the coordinate plate 2. At the same time, the probe 411 and the coordinate plate 2 and the optical sensor may not be able to receive or transmit signals normally due to the obstruction of snow, resulting in inaccurate measurement data such as displacement and angle. For some sensors based on contact measurement, water after the snow melts may enter the sensor, damage the electronic components, and affect the measurement accuracy. When the supporting gear block 402 rotates, it can be seen Figure 3The connecting rod drives the positioning sliding cavity frame 501 to rotate along the motor assembly 401. The positioning sliding cavity frame 501 carries the electric telescopic rod 504 and the cleaning brush 506 below it to clean the track side of the large-span steel structure on the coordinate plate 2 when sliding at high altitude, so as to avoid the interference of dust and snow on the measuring tool. At the same time, according to the actual position of the coordinate plate 2, the electric telescopic rod 504 performs telescopic movement, so that the cleaning brush 506 and the inclined connecting block 507 are attached to the upper surface of the coordinate plate 2, and the gear slider 502 will not be disturbed by the movement of the electric telescopic rod 504 through the sliding cavity on the electric telescopic rod 504, and it is still engaged with the corresponding plug-in block 503. According to the thickness of the garbage or snow accumulated on the coordinate plate 2, the cleaning brush 506 and the inclined connecting block 507 are driven by the reaction force of the garbage or snow to drive the corresponding plug-in block 503 to move upward along the electric telescopic rod 504, and the transmission chain 508 and the support The meshing of the gear block 402 and the gear slider 502 drives the gear slider 502 to rotate, and the gear slider 502 drives the electric telescopic rod 504 to rotate, thereby improving the cleaning ability of the inclined connecting block 507. Since the sliding groove provided on the outer side of the electric telescopic rod 504 does not interfere with the corresponding plug-in block 503 rotating or sliding along the sliding groove, and there is a spring between the electric telescopic rod 504 and the corresponding plug-in block 503, when the cleaning bristles 506 and the inclined connecting block 507 are in a close fit with the garbage or snow, the friction between the two is large, and the corresponding plug-in block 503 has a certain degree of torsion along the surface of the electric telescopic rod 504. As the cleaning bristles 506 and the inclined connecting block 507 follow the probe 411 away from the coordinate plate 2, the torsion restores the inclined connecting block 507 and the cleaning bristles 506 to their original positions. At this time, the garbage or snow adsorbed by the cleaning bristles 506 and the inclined connecting block 507 is shaken off to avoid affecting the later cleaning.
