DETAILED DESCRIPTION

[0033] The embodiment of the present application discloses a high-altitude steel beam segment assembly fine-tuning device close to the railway operating line.

[0034] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Embodiment 1:

[0036] Reference Figure 1 , Figure 3 and Figure 4The embodiment of the present application discloses a high-altitude steel beam segment assembly fine-tuning device close to a railway operating line, including a through-type jack 5, which passes through and is fixedly arranged on one side of the top of a steel cross plate 4, a jack piston 502 is arranged inside the through-type jack 5, a steel strand 503 is passed through the inside of the jack piston 502, a steel cable clamp 504 is arranged on the outside of one end of the steel strand 503, a displacement sensor 505 is fixedly arranged on the top of the jack outer cylinder 501, and the displacement sensor 505 is fixedly arranged on the outside of the jack outer cylinder 501, and the jack piston 502 is connected to the sliding contact of the displacement sensor 505.

[0037] Before installing the through-type jack 5, the steel strand 503 is pre-tensioned to make it in a taut state to ensure that the through-type jack 5 will not relax due to the ups and downs of the steel beam segment. When adjusting the second steel beam segment 301, the through-type jack 5 is started to form a tensioning force on the steel strand 503, and the displacement sensor 505 will change at the same time, and the measured value will be transmitted back to the microcontroller 6 and transmitted to the external main controller for monitoring until the second steel beam segment 301 moves to the set size position and the through-type jack 5 stops running, thereby achieving the effect of automatic and precise adjustment of the second steel beam segment 301.

[0038] Among them, the through-type jack 5 is externally connected to a hydraulic cylinder, a microcontroller 6 is fixedly arranged on the top of the steel cross plate 4, the through-type jack 5 and the displacement sensor 505 are electrically connected to the microcontroller 6, and the microcontroller 6 is communicatively connected to the external main controller.

[0039] The required height adjustment up or down is inputted through the external main controller, and the microcontroller 6 receives the instruction and executes it.

[0040] See also Figure 1 A first steel beam segment 3 and a second steel beam segment 301 are also provided. The first steel beam segment 3 is provided on one side of the concrete tower column 1, the second steel beam segment 301 is provided on one side of the first steel beam segment 3, the steel support frame 2 is provided on the top of the first steel beam segment 3, and a steel cross plate 4 is detachably provided on the outer side of the top of the steel support frame 2.

[0041] Among them, the steel cross plate 4 can be moved through the steel support frame 2, which is convenient for assembly work.

[0042] See also Figure 1 and Figure 2The first steel beam segment 3 and the second steel beam segment 301 are detachably provided with guide rails on both sides of the top end, and multiple pulleys 201 are provided on both sides of the bottom end of the steel support frame 2. Fixed slides 202 are detachably provided on both sides of the steel support frame 2. The fixed slides 202 are slidably provided on the outside of the guide rails, and the pulleys 201 are rollingly provided on the top of the guide rails. A cable 401 is fixedly provided on one side of the top end of the steel support frame 2, and the cable 401 is fixedly provided on the top end of the steel cross plate 4.

[0043] Among them, the steel support frame 2 can move at the top of the guide rail through the setting of multiple pulleys 201, and the fixed slide 202 will slide on the outside of the guide rail when moving, which is used to prevent the steel support frame 2 from derailing when moving. The setting of the cable 401 enhances the rigidity of the steel cross plate 4 and improves the stability of the structure.

[0044] Embodiment 2:

[0045] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The connecting mechanism 7 includes a locking structure 8, and the locking structure 8 includes a connecting plate 801. The connecting plate 801 is detachably arranged at the bottom end of the steel cable clamp 504. A pull column spring 802 and a connecting steel shell 806 are fixedly arranged at the bottom end of the connecting plate 801. The pull column spring 802 is arranged on the inner side of the connecting steel shell 806. A downward pressure guide column 803 is fixedly arranged on the other end of the pull column spring 802. A pressing tongue is arranged at one end of the downward pressure guide column 803. Tongue grooves are symmetrically provided on the outer side of the connecting steel shell 806, and the pressing tongue is slidably arranged on the inner side of the tongue groove.

[0046] When in use, the tongue is directly pressed down, and the tongue slides in the tongue groove, so that the pressing guide column 803 can be lowered, thereby driving the contact guide column 805 to be lowered together, so that the latch assembly 9 can achieve the effect of locking the interlocking cylinder seat 10, and the pull column spring 802 is in an extended state at this time, so that when unlocking, the pressing guide column 803 can return to its original position by the elastic force of the pull column spring 802.

[0047] Among them, a touch guide column 805 is set at the other end of the downward pressure guide column 803, a connecting ring frame 807 is fixedly set at the bottom end of the connecting steel shell 806, the downward pressure guide column 803 slides through the top of the connecting ring frame 807, and a ring clamping groove 804 is opened on the outer side of the touch guide column 805.

[0048] Among them, the touch guide column 805 is in contact with the latch assembly 9, so that the latch assembly 9 can achieve a locking effect. Among them, the downward pressing guide column 803 can slide on the inner side of the connecting ring frame 807 to facilitate its descent or rise. The opening of the ring groove 804 facilitates the locking arc plate 812 to be inserted therein, so that the downward pressing guide column 803 and the touch guide column 805 are fixed when in use, thereby assisting the latch assembly 9 to achieve a locking effect.

[0049] It should be noted that, see Figure 6 Both sides of the bottom end of the unlocking guide plate 810 and the side close to the docking angle block 811 are provided with slopes, and the side away from each other of the locking arc plate 812 is fixedly provided with a return spring 813, and the return spring 813 is fixedly provided on one side of the first bracket 814.

[0050] Due to the setting of the slope, when the unlocking guide plate 810 descends, the docking angle block 811 will move to both sides and separate, and the docking angle block 811 will drive the two locking arc plates 812 to move away from each other, so that the locking arc plate 812 leaves the ring groove 804 and contacts the locking state of the downward pressure guide column 803. At the same time, the reset spring 813 will be compressed, and the locking arc plate 812 will fit the outer wall of the touch guide column 805. When the touch guide column 805 moves up and down, the locking arc plate 812 will slide along the outer wall of the touch guide column 805. It should be noted that due to the setting of the first bracket 814, the second bracket 815 and the connecting ring frame 807, the locking arc plate 812 will not move up and down.

[0051] In this embodiment, see Figure 1 , Figure 3 , Figure 7 and Figure 8 The connecting mechanism 7 also includes a latch assembly 9, which includes a lock shell 901, a lock slot 902 is symmetrically provided on the outer side of the lock shell 901, a latch tongue 903 is slidably provided on the inner side of the lock slot 902, a contact block 905 is fixedly provided on the top side of the latch tongue 903, a magnet 904 is fixedly provided on the side where the latch tongues 903 are close to each other, a latch hole 1001 is symmetrically provided on the outer side of the locking cylinder seat 10, and a fixed base 1002 is detachably provided on the bottom end of the locking cylinder seat 10, and the fixed base 1002 is fixedly provided on the top of the second steel beam segment 301.

[0052] When the guide column 805 descends, it will press the abutment block 905 in the latch assembly 9. Since the side where the abutment blocks 905 are close to each other is provided with a sliding slope 906, the abutment block 905 will drive the latch tongues 903 to move away from each other, and the latch tongues 903 will slowly slide out from the inner side of the lock slot 902 and enter the latch hole 1001. At this time, the connecting mechanism 7 can lock the interlocking cylinder seat 10, and then the steel strand 503 is connected to the second steel beam segment 301 through the connecting mechanism 7, which is convenient for precise adjustment of the second steel beam segment 301 and assembly work.

[0053] When unlocking, the guide column 805 slowly leaves the locking tongue 903, and the locking tongue 903 will move closer to each other through the suction force of the magnet 904, and the locking tongue 903 will enter the lock slot 902, so that the connecting mechanism 7 can leave the locking cylinder seat 10. Two magnets 904 are arranged on one side of the locking tongue 903 to balance the locking tongue 903. Due to the arrangement of the first bracket 814, when the locking tongue 903 stops moving, the locking tongue 903 will return to the initial position to facilitate the next use. The magnets 904 arranged on the two locking tongues 903 are of different poles, which is convenient for resetting the locking tongue 903. This structure is simple and convenient to use, and improves the assembly accuracy and efficiency.

[0054] A sliding slope 906 is provided on one side of the abutting blocks 905 that are close to each other, and the abutting blocks 905 are slidably disposed at the bottom end of the first bracket 814 .

[0055] When the contact guide post 805 descends and contacts the sliding slope 906, the abutment block 905 moves to both sides, and the two abutment blocks 905 move away from each other, so that the locking tongue 903 moves out from the inner side of the lock slot 902, completing the work of locking the interlocking cylinder seat 10, thereby achieving the connection effect.

[0056] Working principle: The first steel beam segment 3 is installed on one side of the concrete tower column 1, and guide rails are installed on both sides of the top of the concrete tower column 1. Then, the steel support frame 2 is installed on the top of the first steel beam segment 3. The steel support frame 2 can be moved by the pulley 201, and the fixed slide 202 will slide along the guide rail to prevent the steel support frame 2 from falling off the guide rail.

[0057] The required height adjustment up or down is input through the external main controller, and the microcontroller 6 receives the instruction and executes it. The jack piston 502 is driven by hydraulic oil inside the jack outer cylinder 501 and forms a tension force on the steel strand 503. The displacement sensor 505 changes at the same time and transmits the measured value back to the microcontroller 6 and to the external main controller for monitoring until the second steel beam segment 301 moves to the set size position, and the through-type jack 5 stops running, thereby achieving the effect of automatic and precise adjustment of the second steel beam segment 301. In this construction process, the amount of labor used is reduced, and the assembly efficiency and accuracy are improved. Then, the first steel beam segment 3 and the second steel beam segment 301 are assembled. After completion, the connecting mechanism 7 is unlocked, and the steel support frame 2 is continuously moved to assemble the next steel beam.

[0058] Among them, when the steel beam segment is preliminarily assembled, the total station can be used for initial positioning, and compared with the positioning coordinate point to determine the adjustment height of the steel beam up or down, so as to facilitate fine adjustment of the steel beam segment. Before installing the through-type jack 5, the steel strand 503 is pre-tensioned to keep it in a taut state to ensure that the through-type jack 5 will not relax due to the ups and downs of the steel beam segment;

[0059] When the connecting mechanism 7 is connected to the locking cylinder seat 10, the connecting mechanism 7 enters the locking cylinder seat 10, and then the pressing tongue presses down the pressing guide column 803. At this time, the pull column spring 802 is in an extended state, and the contact guide column 805 will press the abutment block 905 in the latch assembly 9. Since the side of the abutment blocks 905 close to each other is provided with a sliding slope 906, the abutment block 905 will drive the latch tongue 903 to move away from each other, and the latch tongue 903 will slowly slide out from the inner side of the lock slot 902 and enter the latch hole 1001. At this time, the connecting mechanism 7 can lock the locking cylinder seat 10, and then the steel strand 503 is connected to the second steel beam segment 301 through the connecting mechanism 7, which is convenient for precise adjustment of the second steel beam segment 301 and assembly work;

[0060] It should be noted that when the connection mechanism 7 is in the connected state, the locking arc plate 812 enters the ring groove 804, and the reset spring 813 is in the released original length state. When the connection mechanism 7 is not in the connected state, the reset spring 813 is in the compressed state, and the locking arc plate 812 fits the outer wall of the contact guide column 805. When the locking arc plate 812 enters the ring groove 804, the docking angle blocks 811 are close to each other and contact the unlocking guide plate 810. With this connection structure, the second steel beam segment 301 will not shake left and right when being adjusted, thereby improving the stability during assembly and reducing the difficulty of adjustment.

[0061] After the assembly is completed, when the connecting mechanism 7 needs to be unlocked, the compression plate 809 is directly pressed down, so that the unlocking guide plate 810 can separate the docking corner blocks 811 on both sides, forcing the docking corner blocks 811 to move away, and the locking arc plate 812 will leave the ring groove 804, and the reset spring 813 will be slowly compressed, and the downward pressing guide column 803 will slowly rise due to the resilience of the pull column spring 802. At this time, the locking tongues 903 will move closer to each other through the suction force of the magnet 904, and the locking tongues 903 will enter the lock groove The opening 902 is convenient for the connecting mechanism 7 to leave the locking cylinder seat 10, and two magnets 904 are arranged on one side of the locking tongue 903 to balance the locking tongue 903. Due to the arrangement of the first bracket 814, when the locking tongue 903 stops moving, the locking tongue 903 will return to the initial position to facilitate the next use. The magnets 904 arranged on the two locking tongues 903 are of opposite poles, which is convenient for resetting the locking tongue 903. This structure is simple and convenient to use, and improves the assembly accuracy and efficiency.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
