One end of the horizontally adjustable hydraulic telescopic rod 330 is fixed on the vertical plate 320, and the other end is against the side of the continuous beam box beam bottom plate 120.

[0049] In some embodiments, please refer to Figure 6 and Figure 7, the horizontal deviation adjustment unit 300 also includes a clamping device 340, the clamping device 340 includes a clamping base 341 installed on the bottom template 001, and an L-shaped connecting cylinder 342 installed on the side of the bottom plate 120 of the continuous beam box beam, and the bottom of the L-shaped connecting cylinder 342 is clamped in the clamping base 341. Specifically, after the bottom template 001 of the main truss of the hanging basket is temporarily fixed, the limit box 310 is temporarily welded and installed on the bottom template 001. The limit box 310 is designed to be hollow inside, three sides are closed, one side is open, and the upper surface is half open. One end of the half-open surface of the limit box 310 is connected, and the other end is open. The base 321 is a rectangular parallelepiped design, and the size is slightly smaller than the hollow size of the limit box 310. The vertical plate 320 is vertically installed at the center position (long axis) of the surface of the base 321, and the plate thickness is slightly smaller than the half-open width size of the upper surface of the limit box 310. When the limit box 310 is installed, the base 321 and the vertical plate 320 form an inverted T-shaped and are embedded in the limit box 310 from the side of the opening of the limit box 310, and the vertical plate 320 extends out of the limit box 310 from the half-open position on the upper surface.

A horizontal control sub-control module 350 is installed at the top position of the vertical plate 320. When the positioning monitoring device provided by the present invention detects that the forward movement direction of the bottom template 001 is not in place, the horizontal control sub-control module 350 receives the instruction to perform the corresponding extension operation, and accordingly drives the bottom template 001 to slide forward until it reaches the specified position. After the bottom template 001 is in place, a clamping base 341 is installed at the horizontal midpoint of the bottom template 001 5 cm in front of the intersection of the bottom template 001 and the bottom plate 120 of the continuous beam box girder. The clamping base 341 is a solid rectangular concave design, and the concave position is the center position of the upper surface of the cube. The concave is a circular hole, and the hole diameter matches the cylinder diameter of the L-shaped connecting cylinder 342. There is a mounting plate 343 at the horizontal center position of the bottom of the front side of the continuous beam box girder bottom plate 120, which is temporarily fixed and installed with expansion bolts. An L-shaped connecting cylinder 342 is installed at the center of the mounting plate 343, and the other vertical end of the L-shaped connecting cylinder 342 faces downward and is inserted into the center hole of the clamping base 341.

After the bottom template 001 is adjusted in place, the rear anchor fixing system is used to lock and fix the positions of the bottom plate 120 of the continuous beam and box beam, the bottom template 001 and the bottom longitudinal beam 140.

[0051] In the entire formwork system, the hanging basket body 100 is the main structural part of the hanging basket and is the carrier of the entire device; the positioning monitoring device provided by the present invention is the center of the entire system and is used to monitor the actual coordinates of the bottom template 001; the vertical deviation adjustment unit 200 and the horizontal deviation adjustment unit 300 are the auxiliary control systems of the entire device and are used to perform vertical adjustment, front and rear adjustment, and left and right adjustment of the bottom template 001; the rear anchor fixing system is the anchoring system of the entire device and is used to achieve a fixed connection between the hanging basket body 100 and the cast beam section.

[0052] In some embodiments, please refer to Figure 8 The upper rear anchor unit 510 includes an anchoring threaded rod 511, a baffle 512 and a hydraulic jack telescopic rod 513. The anchoring threaded rod 511 passes through the baffle 512, the longitudinal beam 130 of the main truss of the triangular hanging basket, the walking track 150 and the top plate 110 of the continuous beam box girder from top to bottom in sequence, and nuts are screwed into the anchoring threaded rod 511 from the upper and lower ends to achieve anchoring.

The other end of the hydraulic jack telescopic rod 513 is against the lower surface of the baffle 512. An upper anchoring nut 515 is installed on the upper surface of the baffle 512 and is temporarily screwed with the anchoring threaded rod 511. When the main truss of the triangular hanging basket moves forward to its position, the manually operated jack 514 controls the hydraulic jack telescopic rod 513 to stretch upward. When the locking distance between the anchor threaded rod 511 and the upper / lower anchor nuts 515 / 516 remains unchanged, the baffle 512 is tightly pressed, and the hydraulic jack telescopic rod 513 rises, which in turn drives the longitudinal beam 130 of the main truss of the triangular hanging basket to press downward. After the front end of the triangular hanging basket is locked, the rear end of the triangular hanging basket is also slowly locked accordingly.

Nuts are screwed into the rear anchor threaded rod 521 from the upper and lower ends respectively. The bottom template 001 is sandwiched between the continuous beam box beam bottom plate 120 and the bottom longitudinal beam 140. Specifically, the rear anchor threaded rod 521 penetrates the stopper 522, the pad 523, the reserved hole of the continuous beam box beam bottom plate 120, and the bottom longitudinal beam 140. The rear anchor threaded rod 521 has a threaded thread. The bottom surface of the bottom longitudinal beam 140 is equipped with a lower rear anchor nut 525. The bottom template 001 is installed between the bottom longitudinal beam 140 and the bottom surface of the continuous beam box beam bottom plate 120. The pad 523 is laid on the upper surface of the continuous beam box girder bottom plate 120, and a rear anchor hydraulic jack 526 is installed on the surface of the pad 523. A rear anchor hydraulic jack telescopic rod 524 is embedded and installed inside the rear anchor hydraulic jack 526, and the other end of the rear anchor hydraulic jack telescopic rod 524 supports the bottom surface of the block 522. An upper rear anchor nut 527 is installed on the upper surface of the block 522. A rear anchor sub-control module 528 is installed on the side of the block 522. After the rear anchor threaded rod 521 and the upper / lower rear anchor nuts 527 / 525 are all screwed together, when the rear anchor sub-control module 528 receives the rear anchor locking instruction, it can control the rear anchor hydraulic jack 526 to adjust the rear anchor hydraulic jack telescopic rod 524 to perform a stretching operation, thereby driving the block 522 to slowly lift, and further realize the anchor locking between the continuous beam box girder bottom plate 120, the bottom template 001, and the bottom longitudinal beam 140.

After receiving the command, the vertical rod hydraulic adjustment controller 462 controls the vertical rod hydraulic adjustment telescopic rod 461 to perform a contraction or extension operation, and accordingly drives the rotating sub-control platform 414 to perform an upward or downward operation. A rotating control motor 415 is installed at the center position of the upper surface of the rotating sub-control platform 414, and is fixedly installed with its lower surface. A coaxial shaft is fixedly connected to the top rotation position of the rotation control motor 415 , and the other end of the coaxial shaft is fixedly connected to the center of the bottom plate of the mounting base 416 .A pair of connecting rods are installed on the surface of the mounting base 416, and the other ends of the connecting rods are fixedly connected to the bottom of the prism 417. A direction sensing transmitting end 418 is installed on the top of the prism 417. The direction sensing transmitting end 418 determines whether the direction is correct by emitting a single light wave and whether the reflected information is received. When the rotation control motor 415 receives a clockwise / counterclockwise rotation instruction, it performs a rotation operation, and correspondingly drives the coaxial axis to operate synchronously, thereby driving the mounting base 416 to perform a corresponding rotation operation, thereby driving the prism 417 to perform rotation alignment. A laser rangefinder 441 is vertically installed on the upper surface of the central control platform 413, which is 5 cm away from the midpoint of one end of the short side of the vertical centering rod 411. The laser emission direction is kept perpendicular to the upper surface of the central control platform 413. The laser alignment direction is the rotating sub-control platform 414. A scale adjustment ruler 442 is vertically installed between the central control platform 413 and the rotating sub-control platform 414 at the symmetrical position on the other side of the vertical centering rod 411. At the same time, a main control module 450 is installed on the side of the central control platform 413 near the adjustment rod 412. An inclinometer 443 is installed on the vertical centering rod 411 at the intersection of the vertical centering rod 411 and the central control platform 413. The vertical height adjustment of the prism 417 needs to be adjusted with the help of manual observation and an external auxiliary terminal 419. When manual observation finds that there is an obstruction between the fully automatic total station 420 and the prism 417, the height of the prism 417 needs to be raised or lowered. The manually controlled external auxiliary terminal 419 feeds back the vertical adjustment data of the prism 417 to the main control module 450. After receiving the data, the main control module 450 sends an adjustment command to the vertical rod sub-control module 463. After receiving the command, the vertical rod sub-control module 463 sends an adjustment command to the vertical rod hydraulic adjustment controller 462. After receiving the command, the vertical rod hydraulic adjustment controller 462 controls the vertical rod hydraulic adjustment telescopic rod 461 to perform a contraction or extension operation, and correspondingly drives the rotating sub-control platform 414 to perform an upward or downward operation, and further drives the prism 417 to perform an upward or downward operation until there is no obstruction between the prism 417 and the fully automatic total station 420.

[0055] The automatic total station 420 and the total station tripod 421 can both adopt commonly used instruments and equipment on the market, and a direction sensing receiving end 422 is installed at the top position of the automatic total station 420. Considering that the initial direction of the automatic total station 420 is not necessarily aligned with the direction of the prism 417, the direction sensing receiving end 422 is designed as a sphere and embedded in the center position of the top of the automatic total station 420, which is consistent with the center point of the automatic total station 420. No matter how the automatic total station 420 is rotated, the center point remains unchanged. At this time, no matter where the light wave emitted by the direction sensing transmitting end 418 comes from, as long as the direction sensing receiving end 422 is reflected, the direction is aligned. The main control module 450 sends a slow rotation instruction to the rotation control motor 415. At this time, the direction sensing transmitting end 418 continuously transmits light wave induction until the light wave information reflected by the direction sensing receiving end 422 is received, and the main control module 450 is fed back to stop the rotation information. After receiving the information, the main control module 450 issues a stop rotation command, at which time the prism 417 is aligned with the automatic total station 420. The automatic total station 420 automatically identifies and obtains the orientation of the prism 417, monitors the coordinates of the monitoring point, and feeds the coordinate data back to the main control module 450.

[0056] The present invention also provides a method for using the above-mentioned hanging basket bottom mold positioning monitoring device, comprising the following steps:

[0057] Step 1: Perform a leveling operation on each prism leveling device 410 to make the vertical centering rod 411 in a vertical state;

[0058] Step 2: Adjust the vertical height of the prism 417 so that there is no obstruction between the fully automatic total station 420 and the prism 417;

[0059] Step 3: Adjust the direction of the prism 417 so that the light wave information emitted by the direction sensing transmitting end 418 can be reflected back to the direction sensing transmitting end 418 by the direction sensing receiving end 422;

[0060] Step 4: Based on the reflected signal received by the direction sensing transmitting end 418 , the distance between the direction sensing receiving end 422 and the direction sensing transmitting end 418 is calculated to obtain the coordinate information of the bottom template 001 .

[0061] The specific operation of the hanging basket bottom mold positioning monitoring device is as follows:

[0062] Step 1: Leveling operation of the three prism leveling devices 410 on the left, middle and right sides.

[0063] First, adjust the prism 417 horizontally, assuming that the direction perpendicular to the box beam structure is x, and the direction parallel to the box beam structure is y:

[0064] The inclinometer 443 monitors the horizontal angle deviation of the vertical centering rod 411 and feeds back the collected data to the main control module 450. After receiving the deviation data, the main control module 450 analyzes the horizontal angle deviation in the x direction. If there is no deviation in the x direction, it means that the vertical centering rod 411 is in a vertical state and no adjustment is required. If there is a deviation in the x direction, the main control module 450 issues a telescopic length consistency instruction to the adjusting rod sub-control module 473 corresponding to the two adjusting rods 412. After receiving the instruction, the adjusting rod sub-control module 473 sends corresponding adjustment instructions to the two adjusting rod hydraulic adjustment controllers 472 according to the deviation value of the two adjusting rod hydraulic adjustment telescopic rods 471. After receiving the corresponding instruction, the adjusting rod hydraulic adjustment controller 472 controls the corresponding adjusting rod hydraulic adjustment telescopic rod 471 to perform a stretching or contraction operation until the telescopic lengths of the two adjusting rod hydraulic adjustment telescopic rods 471 are consistent. At this time, the y direction of the vertical centering rod 411 is in the centerline state, and there is no deviation in the x direction.

[0065] The inclinometer 443 again monitors the horizontal angle deviation of the vertical centering rod 411, and feeds the data back to the main control module 450. After receiving the deviation data, the main control module 450 performs horizontal angle x-direction and y-direction deviation analysis again. The x-direction deviation monitoring is to verify the previous operation. If there is no deviation in the y-direction, it means that the vertical centering rod 411 is in a vertical state and no adjustment is required. If there is a deviation in the y-direction, the main control module 450 issues an instruction to the adjusting rod sub-control module 473 corresponding to the two adjusting rods 412 to stretch the telescopic length synchronously and keep the stretching value consistent. After receiving the instruction, the adjusting rod sub-control module 473 sends corresponding adjustment instructions to the two adjusting rod hydraulic adjustment controllers 472 according to the deviation value of the two adjusting rod hydraulic adjustment telescopic rods 471. After receiving the corresponding instruction, the adjusting rod hydraulic adjustment controller 472 controls the corresponding adjusting rod hydraulic adjustment telescopic rod 471 to perform the stretching operation synchronously. The stretch value of the adjustment rod hydraulic adjustment telescopic rod 471 is adjusted in sections and grades. After each section of fine adjustment, the y-direction angle deviation is measured by the inclinometer 31 until the horizontal angle deviation of the vertical centering rod 411 is cut off at 0°. At this time, the prism 417 is in a leveling state. It should be noted that the y-direction deviation adjustment is graded as follows: the stretch value is adjusted by 5cm for a deviation of more than 10°; the stretch value is adjusted by 3cm for a deviation of 5-10°; the stretch value is adjusted by 1cm for a deviation of 2-5°; the stretch value is fine-tuned by 2mm for a deviation of 0-2°.

[0066] Then the prism 417 is adjusted vertically:

[0067] After the prism 417 is leveled, the distance from the central control platform 413 to the bottom template 001 is manually measured, assuming the distance is m (including the thickness of the central control platform 413). In addition, the distance from the rotating sub-control platform 414 to the center of the prism 417 is measured in advance, assuming the distance is n (including the thickness of the rotating sub-control platform 414).

[0068] The vertical height adjustment of the prism 417 needs to be adjusted with the help of manual observation and the external auxiliary terminal 419. When it is manually observed that there is an obstruction between the fully automatic total station 420 and the prism 417, the height of the prism 417 needs to be raised or lowered. The manually controlled external auxiliary terminal 419 feeds back the vertical adjustment data of the prism 417 to the main control module 450. After receiving the data, the main control module 450 sends an adjustment command to the vertical rod sub-control module 463. After receiving the command, the vertical rod sub-control module 463 sends an adjustment command to the vertical rod hydraulic adjustment controller 462. After receiving the command, the vertical rod hydraulic adjustment controller 462 controls the vertical rod hydraulic adjustment telescopic rod 461 to perform a contraction or extension operation, and correspondingly drives the rotating sub-control platform 414 to perform an upward or downward operation until there is no obstruction between the prism 417 and the fully automatic total station 420. The external auxiliary terminal 419 sends a vertical adjustment completion message to the main control module 450, and sends m and n to the main control module 450. After receiving the information, the main control module 450 issues a distance measurement command to the laser rangefinder 441. After receiving the command, the laser rangefinder 441 performs a distance measurement operation, measures the distance (assuming it is h) between the rotating sub-control platform 414 and the central control platform 413, and feeds it back to the main control module 450. After receiving the distance measurement data, the main control module 450 converts the final height (m+n+h) of the prism 417, and can manually check it through the scale adjustment ruler 442. At this time, the vertical adjustment of the prism 417 is completed.

[0069] Finally, the direction of prism 417 is positioned:

[0070] After the height adjustment of the prism 417 is completed, the main control module 450 sends a slow rotation command to the rotation control motor 415. At this time, the direction sensing transmitting end 418 continues to transmit light wave sensing until it receives the light wave information reflected by the direction sensing receiving end 422, and then feeds back the stop rotation information to the main control module 450. After receiving the information, the main control module 450 issues a stop rotation command, and at this time, the prism 417 and the fully automatic total station 420 are aligned in direction.

[0071] After the positioning monitoring device is installed and detected in place, the steps of using the positioning monitoring device, the vertical deviation adjustment unit 200 and the horizontal deviation adjustment unit 300 to level the mold are as follows:

[0072] 1. Horizontal adjustment of bottom template 001.

[0073] The fully automatic total station 420 automatically identifies and obtains the positions of the left, middle, and right prisms 417, monitors the coordinates of the monitoring points, and feeds the coordinate data back to the main control module 450. The main control module 450 receives the data and analyzes the data for the three points of the middle prism, the left prism, and the right prism.

[0074] First, the bottom template 001 is adjusted longitudinally (front and back) (the x-axis is the transverse direction of the bridge, and the y-axis is the longitudinal direction of the bridge):

[0075] First, determine whether the y coordinate of the monitoring point of the middle prism 417 meets the requirements. If the y coordinate does not meet the requirements, it means that the forward movement direction of the bottom template 001 has not yet reached the position. The main control module 450 calculates the distance that has not been reached, and sends a push-out instruction to the horizontal control sub-control module 350 of the middle adjustment device. When the horizontal control sub-control module 350 receives the instruction, it performs the corresponding push-out operation, and accordingly drives the bottom template 001 to slide forward until it reaches the specified position. At this time, the bottom template 001 has moved. In order to ensure the accuracy of the data, the prism leveling device 410 needs to be leveled again. After the prism 417 is leveled in place, the fully automatic total station 420 collects and obtains the y coordinate data of the monitoring point of the middle prism 417 again and sends it to the main control module 450. The main control module 450 determines again whether the bottom template 001 has moved forward in place. If it has not been in place, the above steps are performed again. If it is in place, the next step is performed.

[0076] After the bottom template 001 is in place, the clamping device 340 is installed. After the installation is completed, the L-shaped connecting cylinder 342 is inserted into the central hole of the clamping base 341. At this time, a movable clamping connection is formed between the continuous beam box beam bottom plate 120 and the bottom template 001, that is, the rear end transverse center point of the bottom template 001 is temporarily fixed to the front end transverse center point of the continuous beam box beam bottom plate 120. At this time, the bottom template 001 is longitudinally adjusted in place.

[0077] 2. Horizontal (left and right) adjustment of bottom template 001:

[0078] The main control module 450 analyzes and determines whether there is a deviation in the central axis of the bottom template 001 according to the x-coordinate of the middle prism 417 collected in the above steps. If there is no deviation, the vertical adjustment work of the bottom template 001 is performed. If there is a deviation, the deviation direction (left or right) is converted. If it is left, the main control module 450 sends a push-out instruction to the horizontal adjustment sub-control module 350 of the left adjustment device. When the horizontal adjustment sub-control module 350 receives the instruction, it performs the corresponding push-out operation. When the horizontal center of the rear end of the bottom template 001 is temporarily fixed, the left side performs a push-out operation, which drives the front end of the bottom template 001 to adjust to the right. Similarly, the right side performs a push-out operation, which drives the front end of the bottom template 001 to adjust to the left, and finally drives the front end midpoint and the rear end midpoint of the bottom template 001 to continuously meet the requirements of the bridge centerline layout. It should be noted that, in order to ensure the accuracy of the data, the prism leveling device 410 needs to be leveled each time the prism is adjusted. After the prism is leveled, proceed to the next step and repeat the above steps until there is no deviation in the center axis of the bottom template 001.

[0079] 3. Vertical adjustment of bottom template 001:

[0080] The main control module 450 analyzes the z coordinates of the middle, left and right prisms 417 collected in the above steps to determine whether the mold elevation meets the requirements. If it meets the requirements, it means that the adjustment of the bottom template 001 is completed. If it does not meet the requirements, the main control module 450 converts the vertical deviation value and the pitch of the front hanging nut 240 and other parameters into the number of thread turns that need to be adjusted (assuming it is a), and at the same time issues a clockwise / counterclockwise rotation control instruction to the through-type actuator motor 230 on the corresponding side. When the front threaded hanger 210 and the main body of the through-type actuator motor 230 remain stationary, the through-type actuator motor 230 rotates the shaft to drive the front hanging nut 240 to perform corresponding operations. The front hanging nut 240 and the front threaded hanger rod 210 twist against each other, which correspondingly drives the front threaded hanger rod 210 to move up and down, and further drives the bottom longitudinal beam 140 to move up and down, thereby realizing the vertical deviation adjustment of the bottom template 001 until the left, middle and right formwork elevations of the bottom template 001 meet the requirements.

[0081] The specific calculation method for adjusting the number of turns of the front hanging nut 240 is as follows: Based on the pitch of the front threaded hanging rod 210 (i.e., the axial distance between two points corresponding to two adjacent teeth on the mid-diameter line of the thread), it is assumed to be d. Since the front threaded hanging rod 210 is a standard single-line thread, the forward displacement of the nut for one turn (assuming it is L) can be considered:

[0082] L = d

[0083] Combine the vertical difference of the monitoring point (assuming it is H) and convert it into the number of circles (assuming it is a):

[0084]

[0085] After the bottom template 001 is erected, the clamping device 340 is removed, and the lower rear anchor unit 520 is adjusted at the same time until the continuous beam box beam bottom plate 120, the bottom template 001, and the bottom longitudinal beam 140 are anchored and locked. At this time, the erection and adjustment work of the bottom template 001 of the hanging basket is completed.

[0086] During the entire process, signal transmission between different components in each device is carried out using wireless network transmission.

[0087] The above method combines information technology with mechanical control, so that the manual control of the hanging basket mold is transformed into a more precise and professional fully automated control, achieving the effect of automatic control and rapid positioning when the hanging basket mold is erected, improving work efficiency and promoting the efficient operation of the project.
