[0037] The present invention is described in detail below with reference to the accompanying drawings.

[0038] like Figure 1 As shown, the present invention provides a track construction platform for steel bar binding of a prefabricated box girder top plate, including a steel bar binding frame, the steel bar binding frame including a bracket 1, the bracket 1 is constructed of three parts by a steel rail, a crossbeam 11 is arranged on the left bracket and the right bracket, and a crossbeam 111 is arranged on the middle bracket, the crossbeams 11, 111 are arranged on the bracket 1 at intervals, and are extended along the longitudinal direction of the bracket 1. The left and right crossbeams 11 are sequentially arranged from outside to inside with a track 11, a steel bar longitudinal positioning beam 13, and a steel bar transverse positioning beam 14, and an angle steel beam positioning bracket 16 is arranged on the middle crossbeam 111 for positioning and supporting an angle steel beam 15. The track 11, the steel bar longitudinal positioning beam 13, the steel bar transverse positioning beam 14, the angle steel beam positioning bracket 16, and the steel beam 15 all extend along the longitudinal direction of the bracket 1, that is, along the construction direction of the prefabricated box girder top plate.

[0039] The longitudinal steel bar positioning beam 13 is used to support and position the longitudinally arranged steel bars, and the transverse steel bar positioning beam 14 is used to support and position the transversely arranged steel bars. Notches are arranged at intervals on the transverse steel bar positioning beam 14. The spacing distance of the notches is set according to the arrangement design of the steel bars of the prefabricated box girder top plate. When in use, the steel bars can be directly placed in the notches to complete the transverse spacing positioning of the steel bars.

[0040] The steel bar longitudinal positioning beam 13 includes several spaced-apart vertical steel plates and connecting steel bars between the steel plates, so that a receiving groove is formed between the two steel plates. When in use, the steel bar is longitudinally arranged in the receiving groove, thereby completing the longitudinal positioning of the steel bar.

[0041] The angle steel beam positioning bracket 16 is used to support the angle steel beam 15 , and the angle steel beam 15 is supported on the vertical support rod of the angle steel beam positioning bracket 16 in a right-angled inverted manner.

[0042] The transverse steel bars, longitudinal steel bars and angle steel beams are arranged on the frame strictly according to the design, so that they can be tied to ensure that the tied steel bars are straight and neat.

[0043] refer to Figure 2-7 The track construction platform for tying reinforcement bars of the top plate of a prefabricated box beam of the present invention further comprises a track construction platform, the track construction platform comprises a bottom plate 53, a wheel bracket 531 is arranged below the bottom plate 53, a pulley 251 is arranged on the wheel bracket 531, the pulley 251 can be supported on the track 11 and move along the track 11. In particular, the pulley 251 has a V-shaped slide groove, the track 11 has an inverted V-shaped slide rail, the slide groove and the slide rail are adapted to each other, so that the pulley 251 is stably supported in the slide rail 11 without falling off the rail.

[0044] A transmission system is fixed above the bottom plate 53 , and the transmission system includes a lifting system and a moving system.

[0045] The lifting system includes screw lifters 23 located at the four corners of the base plate 53, and a motor 283 located in the middle of the base plate 53. The screw lifter 23 includes an input shaft 291 and a lifting rod 22. One end of the input shaft 291 is connected to the screw lifter 23, and the other end is connected to the shaft 29. The shaft 29 is supported on the base plate 53 by a bearing. In this way, two parallel shafts 29 are arranged perpendicular to the direction of the track 11, and the four screw lifters 23 are connected into two groups, each group of two linkage combinations. It also includes a motor 283, which is fixed in the middle of the base plate 53, and drives the two parallel shafts 29 to rotate in the same direction through the transfer system 281. Each shaft 29 drives two screw lifters 23, thus forming a lifting device with four screw lifters 23 linkage. The four screw lifters 23 drive their lifting rods 22 to rise and fall under the drive of the drive shaft 291, and a universal wheel 21 is arranged below the lifting rod 22. When the motor 283 rotates forward, the lifting rod 22 extends toward the ground until the universal wheel 21 touches the ground. The lifting height of the bottom plate 53 is adjusted so that the pulley 251 is aligned with the slide rail 11. Then the motor 283 is reversed and the height of the bottom plate is adjusted again so that the lifting rod 22 extends toward the sky. As the bottom plate descends, the pulley 251 is engaged with the track 11. The four screw lifters 23 complete the lifting action synchronously. In this way, the track construction platform can be exempted from hoisting and can achieve the upper and lower rail actions by relying on its own power.

[0046] On the shaft 29, an electromagnetic clutch 24 is provided near each screw lifter 23, and a driving wheel 25 is provided on the side of the electromagnetic clutch 24 away from the screw lifter 23. The fixed part of the electromagnetic clutch 24 is installed on the bottom plate 53, and its input end is the shaft 29, and its output end is the driving shaft 291, so that the input power of the shaft 29 can be input or disconnected to the driving shaft 291 through the electromagnetic clutch. When the platform completes the rail-mounting action, the electromagnetic clutch needs to be disconnected, thereby ensuring that the lifting action of the platform is completed and terminated.

[0047] refer to Figure 6 , shows a mobile system of a track construction platform of the present invention, which includes a driving wheel 25 driven by a shaft 29 fixed above a bottom plate 53, and a pulley 251 fixed below the bottom plate 53 through a support 531, and pulleys or sprockets are arranged on both sides of the V-shaped groove of the pulley 251. The two ends of the driving wheel 25 can be supported by a bearing seat and a bearing 26, and only part of the bearing 26 is schematically shown in the figure. The driving wheel 25 is arranged directly above the pulley 251, and the shaft 29 drives the driving wheel 25 to rotate, and the driving wheel 25 further drives the pulley 251 to rotate through a chain or a belt.

[0048] In this way, the construction platform of the present invention can be lifted and moved by a power system, and has a simple structure and high reliability.

[0049] Reference again Figure 7 , which shows the transfer system of the present application, including a motor 283, the output shaft of the motor 283 is connected to a bevel gear 2811, and the two sides of the bevel gear 2811 are respectively vertically meshed with bevel gears 2812 and 2813. Taking one end as an example, the output shaft of the bevel gear 2813 is equipped with a bevel gear 271 that rotates synchronously, and the bevel gear 271 is meshed with the bevel gear 272 configured on the shaft 29. Thus, the power from the motor 283 is transmitted to the upper and lower shafts 29 through the bevel gears, and the drive shafts 29 rotate synchronously and in the same direction, and the shafts 29 then drive the drive wheels 25 and the pulleys 251 to rotate, so that the construction platform can move along the track 11.

[0050] refer to, Figure 4 On the bottom plate 53 of the present invention, a hollow elongated groove 41 is respectively provided at the four corners, and the elongated groove 41 allows the chain or belt between the driving wheel 25 and the pulley 251 to pass through, and at the same time allows the lifting rod 22 of the screw lifter 23 to pass through.

[0051] In a particular embodiment, the screw lifter 23, the electromagnetic clutch 24, the seat of the bearing 26, and the bracket 531 are all fixedly arranged on both sides of the elongated slot 41. Due to the provision of the elongated slot, the lateral position of the driving wheel 25 can be adjusted, that is, the driving wheel 25 can be adjusted along the length direction of the elongated slot to adapt to the width of the track 11; at the same time, the position of the pulley 251 will also be adjusted accordingly to match the driving wheel. The presence of the elongated slot makes it possible for the mobile construction platform of the present invention to adapt to different types of box beam top plates. It is only necessary to adjust the installation position of the screw lifter 23, the driving wheel 25, and the bracket 531 to achieve adaptation to tracks 11 of different widths. In this way, the adaptability of the product is enhanced.

[0052] refer to Figure 5 The construction platform of the present invention further comprises a cover 52, which covers the top of the bottom plate 53 and covers the lifting, moving and driving system of the present invention from above. The top of the cover 52 is the platform for construction workers to stand.

[0053] The control device 60 and the power line 61 connected to the motor 281 are also included. The control device 60 serves as the power supply system and control system of the motor. The power line is used for external power supply.

[0054] The control device 60 can control the rotation of the motor, for example, timed rotation, so that when the worker completes a certain distance of steel bar binding work, the construction platform automatically moves forward, so that the worker can bind the next section of steel bars. In particular, the control device 60 can be equipped with a remote control device, such as a Bluetooth control device, so that the worker can repeatedly control the mobile construction platform to move forward, backward, or up and down during construction.

[0055] The control device 60 is also electrically connected to the electromagnetic clutch 24 and can disconnect or engage the electromagnetic clutch 24 .

[0056] The present invention also provides an operation method of a track construction platform used for binding reinforcement bars of a prefabricated box girder top plate, comprising the following steps:

[0057] Step 1: constructing a tire frame, which is constructed according to the parameters of the prefabricated box girder top plate to be constructed, ensuring that it can support and position the pre-tied steel bars in a standard and regular manner, and at the same time setting tracks on the tire frame;

[0058] Step 2: Move the construction platform to the front of the tire frame by locomotive traction or manual traction, start the construction platform lifting control, control the electromagnetic clutch 24 to engage through the control device 60, so that the construction platform is raised and the pulley 251 of the construction platform is aligned with the track 11 of the tire frame; and move the construction platform forward for a distance, which is used as the debugging distance; this movement can be achieved by traction or manual push.

[0059] Step 3: Control the construction platform to descend so that the pulley 251 of the construction platform is accurately fitted into the track 11; continue to reverse the motor so that the lifting rod 23 of the construction platform continues to retract until it leaves the ground at a certain height, which does not affect the movement of the construction platform; when the motor is reversed and the lifting rod 23 is retracted, the pulley 251 will drive the construction platform to move backward within the debugging distance;

[0060] Step 4: Control the electromagnetic clutch 24 to be disconnected through the control device 60, so that the rotation of the motor will not be transmitted to the lifting system; at the same time, the motor is rotated forward and reversed, and the equipment is debugged;

[0061] Step 5: After the equipment is debugged, move the construction platform to the specified starting position and start the operation.

[0062] Step 6: The control device 60 drives the motor to rotate at a fixed time, so that the construction platform moves a predetermined distance after a predetermined time. Within the predetermined time, the workers will complete the steel bar binding of the predetermined distance. In this way, the work efficiency of the workers is guaranteed. The predetermined time can be adjusted. At the same time, during the period of timing the motor driving, the motor can also be controlled to stop, forward and reverse at any time to deal with various unexpected or temporary situations.

[0063] The construction platform of the present invention has a high degree of automation, can ensure that the top plate reinforcement is tied straight and regular, ensure construction safety, and improve the construction efficiency of workers.
