Description

Technical Field

[0001] This invention relates to the field of low T-beam assembly technology, and in particular to a digitally controlled construction device for assembling prestressed concrete low T-beams for municipal bridges. Background Technology

[0002] As the nation enters a new stage of development, the number of public welfare projects has increased, and the construction of municipal road networks has significantly improved travel convenience. However, traditional construction methods are insufficient to meet the demands of efficient and rapid development. To adapt to the trends of the times and intelligent transformation, it is urgent to upgrade construction technology towards intelligence, precision, and efficiency to achieve efficient and precise installation of low T-beams for municipal bridges, thereby enhancing the modernization level and technological content of bridge construction.

[0003] In the assembly and construction of prestressed concrete short T-beams for municipal bridges, a large number of construction equipment are used to save construction time and improve efficiency. However, while these equipment are diverse and widely used, precise control is difficult to achieve, especially during crane lifting, where controlling the movement distance of the short T-beams is challenging. This leads to significant errors between the installed short T-beams and their intended positions, affecting their service life. Furthermore, while existing mobile cranes offer high mobility and flexibility, they require precise location positioning each time, hindering efficient rapid deployment. Current technologies also cannot simultaneously control the precise assembly of the short T-beams and the rapid deployment of the construction equipment, failing to save space in the control system and further limiting control efficiency. Therefore, a method is needed that can precisely and efficiently control the assembly position of the short T-beams, save space in the control system, and achieve more efficient rapid deployment, thus addressing the shortcomings of existing short T-beam assembly and construction equipment.

[0015] The advantages of this invention compared to the prior art are:

[0016] The moving device uses a hydraulic control device to drive the hydraulic oil in the retraction cylinder back to the hydraulic control device, causing the retraction plunger to retract upwards. Then, the retraction plunger drives the forward moving component and the locking component to combine and retract into the moving base via the moving connecting rod.

Then, the hydraulic sliding plate drives the hydraulic shaft to rotate through hydraulic oil and hydraulic fan blades, realizing precise control of the micro-movement device. When the second baffle on the conversion assembly is inserted into the partition plate, the first electric actuator drives the hydraulic sliding plate to slide quickly between the two partition plates, causing the hydraulic oil in the retraction cylinder to be drawn back into the hydraulic cylinder, and pressing the hydraulic oil between the two partition plates into the lifting cylinder to control the moving device. This achieves step-by-step control of the micro-movement device and the moving device, thereby saving the space occupied by the hydraulic system.

[0018] When the second electric actuator drives the first baffle to slide down half its stroke, the first baffle drives the conversion lever to switch to a horizontal state. At this time, the first connecting pipe, the second connecting pipe, and the partition plate are all in a semi-open state. When the first electric actuator drives the hydraulic sliding plate to slide between the two partition plates, synchronous control of the support frame and the measuring component can be achieved.

When the second baffle 507 on the conversion assembly 5 is inserted into the partition plate 308, the first electric push rod 302 drives the hydraulic control slide plate 311 to slide rapidly between the two partition plates 308. The hydraulic control slide plate 311 drives the hydraulic oil in the retraction cylinder 404 to flow back between the two partition plates 308, causing the retraction plunger 412 to retract upward. Subsequently, the retraction plunger 412 drives the two forward moving assemblies through the two moving connecting rods 411 respectively. When component 406 retracts inward, the locking plate 419 on the locking base 418 inserts into the locking hole 416 on the forward sliding block 415, realizing the locking function of the locking component 407 for the forward moving component 406. At the same time, the other side of the hydraulic sliding plate 311 drives the hydraulic oil between the two partition plates 308 into the lifting cylinder 401, causing the lifting plunger 402 to be squeezed downward and drive the support frame 405 to slide down. The support frame 405 briefly lifts the moving base 403, thereby helping the two forward moving components 406 to retract inward and improving the conversion efficiency between the moving state and the fixed state. After the forward moving component 406 retracts, the second electric push rod 305 on the hydraulic control device 3 drives the first baffle 501 to slide down half a stroke. At this time, the first baffle 501 drives the conversion lever 504 to rotate horizontally on the conversion bracket 505. Then, the conversion lever 504 on the conversion assembly 5 drives the second baffle 507 to rise halfway through the conversion slider 506, causing the transverse through holes on the first connecting pipe 303, the second connecting pipe 304, and the partition plate 308 to be in a semi-open state. When the first electric actuator 302 drives the hydraulic sliding plate 311 to slide between the two partition plates 308, synchronous control of the support frame 405 and the hydraulic rotating shaft 310 is achieved. This synchronously achieves the support frame 405 driving the overall lifting of the moving device 4 and the hydraulic rotating shaft 310 driving the micro-moving rack 108 to move laterally through the third gear 107. When the conversion lever 504 drives the second baffle 507 from the partition plate 308... When the partition 308 is pulled out, the first baffle 501 closes the first connecting pipe 303 and the second connecting pipe 304. Then, the first electric actuator 302 drives the hydraulic sliding plate 311 to slide slowly between the two partition plates 308. The hydraulic sliding plate 311 drives the hydraulic rotating shaft 310 to rotate through hydraulic oil and hydraulic fan blades 309. The hydraulic rotating shaft 310 drives the measuring turntable 110 on the measuring component 109 to rotate slowly at the upper end of the micro-movement base 101. The measuring turntable 110 rotates slowly through the third gear 107. The third gear 107 drives the micro-movement slider 102 to slide laterally on the micro-movement base 101 through the micro-movement rack 108. The micro-movement slider 102 drives the hoisting device 2 to make lateral fine adjustments, thereby realizing the individual and precise control of the micro-movement device 1.The switching component 5 switches the control mode of the hydraulic control device 3, saving space occupied by the hydraulic control device 3 and improving its control efficiency.

[0047] Specifically, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 12As shown, when the moving device 4 is in a fixed state, the lifting rope is passed through and wound around the three-way hole 202 of the lifting plate 201, and then the lifting rope is fixed to both ends of the short T-beam. At this time, the hydraulic pump in the longitudinal hydraulic cylinder 207 drives the hydraulic oil in the conical seat 104 into the longitudinal hydraulic cylinder 207, causing the longitudinal plunger 206 to drive the transverse plunger 203 and the transverse hydraulic cylinder 204 to lift upward. The transverse plunger 203 drives the short T-beam to lift through the lifting plate 201 and the lifting rope. Then, the motor 105 on the micro-moving slider 102 drives the second gear 106 to rotate. The second gear 106 drives the conical seat 104 to rotate through the first gear 103. The conical seat 104 drives the short T-beam to move through the lifting device 2. Then, the transverse hydraulic cylinder 20... The hydraulic pump in section 4 drives the hydraulic oil in the oil storage counterweight box 205 into the transverse hydraulic cylinder 204, causing the transverse plunger 203 to extend the lifting plate 201 forward. The lifting plate 201 then moves the short T-beam to the top of the pier, realizing the lifting and transfer function of the short T-beam. When the conversion lever 504 pulls the second baffle 507 out of the partition plate 308, the first baffle 501 closes the first connecting pipe 303 and the second connecting pipe 304. Subsequently, the first electric actuator 302 drives the hydraulic control slide plate 311 to slide slowly between the two partition plates 308. The hydraulic control slide plate 311 drives the hydraulic control shaft 310 to rotate through the hydraulic oil and the hydraulic control fan blade 309. The hydraulic control shaft 310 drives the measuring turntable 110 on the measuring component 109 to move slightly. The upper end of the base 101 rotates slowly, and the measuring turntable 110 rotates slowly through the third gear 107. The third gear 107 drives the micro-movement slider 102 to slide laterally on the micro-movement base 101 through the micro-movement rack 108. The micro-movement slider 102 drives the hoisting device 2 to make lateral micro-adjustments, realizing individual and precise control of the micro-movement device 1, thereby allowing the short T-beam to accurately reach the preset position above the pier. Then, the longitudinal hydraulic cylinder 207 drives the short T-beam to descend through the longitudinal plunger 206, so that the short T-beam is close to the preset marked position on the upper surface of the pier. Then, the second electric push rod 305 on the hydraulic control device 3 first drives the first baffle 501 to slide down half a stroke. At this time, the first baffle 501 drives the conversion lever 504 to rotate on the conversion bracket 505. The movement is in a horizontal state. Then, the conversion lever 504 on the conversion component 5 drives the second baffle 507 to rise halfway through the conversion slider 506, so that the transverse through holes on the first connecting pipe 303, the second connecting pipe 304 and the partition plate 308 are all in a semi-open state. When the first electric push rod 302 drives the hydraulic sliding plate 311 to slide between the two partition plates 308, the support frame 405 and the hydraulic rotating shaft 310 are synchronously controlled. Then, the support frame 405 drives the moving device 4 to be lifted as a whole, and the hydraulic rotating shaft 310 drives the micro-moving rack 108 to move laterally through the third gear 107, so that the hoisting device 2 and the short T-beam move obliquely downward, and further align the short T-beam with the pre-marked position on the upper end face of the pier.During the rotation of the positioning turntable 110, the positioning turntable 110 drives the positioning pressure rod 112 to slide on the upper surface of the arc-shaped slide rail 111. When the positioning pressure rod 112 slides to both ends of the arc-shaped slide rail 111, the positioning pressure rod 112 contacts the positioning button 113. At this time, the positioning button 113 sends a position signal to the remote control system, prompting the operator to move the slider 102 to its limit position. The conversion spring 503 on the rotating base 502 is used to convert the rebound of the lever 504. While the support frame 405 drives the moving device 4 to lift as a whole, the insertion rod on the support frame 405 will be pulled out from the insertion hole under the forward moving component 406, so that the forward moving component 406 can slide in the horizontal direction.

[0048] like Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, a ground track is first laid next to the bridge pier. Then, the limiting groove 414 on the forward moving roller 413 is engaged with the ground track, causing the forward moving roller 413 to move along the ground track. Subsequently, the forward moving roller 413 on the forward moving assembly 406 drives the moving device 4 to move to the designated position. When the second baffle 507 on the conversion assembly 5 is inserted into the partition plate 308, the first electric push rod 302 inside the hydraulic control housing 306 drives the hydraulic control slide plate 311 to move between the two... The partition plates 308 slide rapidly between each other, and the hydraulic sliding plate 311 drives the hydraulic oil in the retraction cylinder 404 to flow back between the two partition plates 308, causing the retraction plunger 412 to retract upwards. Subsequently, the retraction plunger 412 drives the two forward moving components 406 to retract inwards through the two moving connecting rods 411, so that the locking plate 419 on the locking base 418 is inserted into the locking hole 416 on the forward moving slide 415, realizing the locking function of the locking component 407 for the forward moving component 406. On the other side of the hydraulic sliding plate 311, hydraulic oil between the two partition plates 308 enters the lifting cylinder 401, causing the lifting plunger 402 to be squeezed downwards and driving the support frame 405 to slide down. The support frame 405 briefly lifts the movable base 403, thereby facilitating the inward retraction of the two forward moving components 406 and improving the efficiency of the transition between the moving and fixed states. After the locking component 407 locks the forward moving component 406, the first electric actuator 302 continues to pass through the hydraulic sliding rod 301. The hydraulic control slide plate 311 slides in the hydraulic control cylinder 307. The hydraulic control slide plate 311 drives the lifting plunger 402 to slide upward through the hydraulic oil. The lifting plunger 402 drives the forward moving component 406 and the locking component 407 to slide upward synchronously through the moving connecting rod 411. The forward moving component 406 drives the moving bracket 409 and the moving slide plate 410 to slide upward synchronously, so that the forward moving component 406 is completely retracted into the matching moving base 403. At the same time, the moving slide column 417 also slides upward in the moving sleeve 408.
