Therefore, they should not be understood as limitations on the present disclosure.
[0024] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0025] like Figures 1 to 7 As shown, it shows a road overweight transport bracket in one embodiment of the present disclosure, including a hollow column 1, a hollow beam 3 and a limit detection frame 4.
[0026] As mentioned above, there are two hollow columns 1, and each hollow column 1 is provided with a hexagonal sliding sleeve 2 on the longitudinal sliding sleeve, and a lifting component 001 that can drive the hexagonal sliding sleeve 2 to move is provided between the hexagonal sliding sleeve 2 and the hollow column 1.
[0027] like Figure 2 and Figure 5 As shown, the two lifting components 001 are symmetrically arranged, and the lifting component 001 includes a lifting ball nut group 6, a lifting screw 7, a bevel gear 1 8, a lifting shaft 9 and a bevel gear 2 10. The lifting ball nut group 6 is arranged in the hollow column 1, and the lifting screw 7 is transmission-arranged in the lifting ball nut group 6. One end of the lifting screw 7 passes through and is rotatably arranged on the hollow beam 3, and the other end passes through the hollow column 1. Bevel gear 1 8 is arranged at one end of the lifting screw 7, and bevel gear 1 8 is located in the hollow beam 3. The lifting shaft 9 is rotatably arranged in the hollow beam 3. Bevel gear 2 10 is arranged on the lifting shaft 9, and bevel gear 2 10 is meshed with bevel gear 1 8.
[0028] Specifically, the rotation of the lifting shaft 9 can drive the bevel gear 2 10 to rotate, the rotation of the bevel gear 2 10 can drive the bevel gear 1 8 to rotate, and the rotation of the bevel gear 1 8 can drive the lifting screw 7 to rotate. When the lifting screw 7 rotates in the lifting ball nut, the lifting screw 7 simultaneously performs longitudinal linear motion. The movement of the lifting screw 7 can drive the hollow beam 3 to move, and the movement of the hollow beam 3 can drive the hexagonal sleeve 2 to move longitudinally in the hollow column 1, thereby realizing the longitudinal height adjustment of the hollow beam 3.
[0029] like Figure 5 As shown, it is supplemented that, in order to improve the stability between the hexagonal sleeve 2 and the hollow column 1, two sleeve limiting parts for positioning the hexagonal sleeve 2 are symmetrically arranged between the hexagonal sleeve 2 and the hollow column 1, and the sleeve limiting part includes a limiting cylinder 11 and a trapezoidal limiting block 12. The limiting cylinder 11 is installed on one side of the hexagonal sleeve 2, and the trapezoidal limiting block 12 is arranged on the output end of the limiting cylinder 11. A number of limiting grooves 13 that are compatible with the trapezoidal limiting block 12 are opened at equal distances on the hollow column 1.
[0030] Specifically, the limit cylinder 11 is started, and the output end of the limit cylinder 11 can drive the trapezoidal limit slider to move. The limit cylinder 11 pushes the trapezoidal limit block 12 to be embedded in the limit groove 13 of the hollow column 1, which can firmly position the hexagonal sleeve 2 to prevent it from shaking or displacement during the detection process, thereby ensuring the stability of the entire bracket during operation.
[0031] like Figure 2 and Figure 6As shown, the hollow beam 3 is arranged on two hexagonal sleeves 2, and a positioning power component 002 is arranged in the hollow beam 3. The positioning power component 002 is connected to the lifting component 001. The positioning power component 002 includes a power shaft 14, a power motor 15 and a lifting power part. The power shaft 14 is rotatably arranged in the hollow beam 3, and the power motor 15 is installed on one side of the hollow beam 3. The output end of the power motor 15 is connected to one end of the power shaft 14. Two lifting power parts are symmetrically provided, corresponding one to one with the lifting component 001, and are used to drive the lifting shaft 9 to rotate.
[0032] The lifting power unit includes a power worm wheel 16 and a power worm 17 . The power worm wheel 16 is arranged on the lifting shaft 9 , and the power worm 17 is arranged on the power shaft 14 . The power worm 17 is meshed with the power worm wheel 16 .
[0033] Specifically, the power motor 15 is started, and the output end of the power motor 15 drives the power shaft 14 to rotate. The rotation of the power shaft 14 can drive the power worm 17 to rotate. The rotation of the power worm 17 can drive the power worm gear 16 to rotate. The rotation of the power worm gear 16 can drive the lifting shaft 9 to rotate, thereby adjusting the position of the hollow beam 3.
[0034] In the present disclosure, when the hollow beam 3 is driven to move by the engagement of the power worm 17 and the power worm wheel 16, not only the position of the hollow beam 3 can be adjusted, but also it has good self-locking performance, which can further improve the stability of the hollow beam 3 after the position is adjusted.
[0035] As mentioned above, there are two limit detection frames 4, and a number of laser detection sensors 5 capable of detecting the position of the vehicle are arranged in sequence on the limit detection frames 4. The limit detection frames 4 pass through the detection and positioning component 003 and are slidably set on the hollow beam 3, and the detection and positioning component 003 is connected to the positioning power component 002.
[0036] Among them, the two detection and positioning components 003 are symmetrically arranged, and the detection and positioning component 003 includes a positioning screw 18, a positioning ball nut group 19 and an adjustment plate 20. The positioning screw 18 is arranged on the power shaft 14, and the positioning ball nut group 19 is transmission-arranged on the positioning screw 18. The positioning plate 20 is penetrated and slidably arranged on the hollow beam 3. One end of the positioning plate 20 is connected to the positioning ball nut group 19, and the other end is connected to the limit detection frame 4.
[0037] Specifically, when the power shaft 14 rotates, the power shaft 14 also drives the adjusting screw 18 to rotate, the adjusting screw 18 can drive the adjusting ball nut group 19 to move, the movement of the adjusting ball nut group 19 can drive the adjusting plate 20 to move, and the movement of the adjusting plate 20 can drive the limit detection frame 4 to move, thereby adjusting the position of the laser detection sensor 5.
[0038] As mentioned above, the laser detection sensor 5 is a sensor that uses laser technology for detection and measurement. Its main function is to measure the width and height of the vehicle. It is a common device in the prior art. The specific structure is not the main innovation of this disclosure and will not be elaborated on here.
[0039] like Figure 7 As shown, it is further explained that in order to prevent external vehicles from colliding with the bracket and causing damage to the bracket, the two sides of the hollow beam 3 are also connected with several anti-collision buffer parts that can sound an alarm. The anti-collision buffer parts include an anti-collision tube 21, an anti-collision rod 22, an anti-collision pad 23, an anti-collision spring 24 and an alarm tube 25. The anti-collision tube 21 passes through and is connected and arranged on one side of the hollow beam 3. The anti-collision rod 22 passes through and is sealed and slidably arranged on the side of the anti-collision tube 21 away from the hollow beam 3. The anti-collision pad 23 is arranged on the side of the anti-collision rod 22 away from the anti-collision tube 21. The bottom of the anti-collision pad 23 is flush with the bottom of the limit detection frame 4. The anti-collision spring 24 is arranged between the anti-collision pad 23 and the hollow beam 3. The anti-collision rod 22 and the anti-collision tube 21 are both located in the anti-collision spring 24. The alarm tube 25 is connected and arranged on the side of the anti-collision tube 21 away from the anti-collision rod 22. An alarm shrapnel 26 is arranged in the alarm tube 25.
[0040] Specifically, when a vehicle accidentally collides with the bracket, the anti-collision rod 22 will compress the anti-collision spring 24, which plays a role in buffering and shock absorption, reducing the damage to the bracket and the vehicle caused by the collision. At the same time, the gas in the anti-collision tube 21 is squeezed during the anti-collision process, causing the alarm shrapnel 26 in the alarm tube 25 to vibrate and emit an alarm, promptly reminding the surrounding people to pay attention to safety. In addition, several warning lights 27 are installed at equal distances on both sides of the hollow beam 3, which can provide obvious warnings to passing vehicles at night or in low-light environments, further improving the safety of road overload transportation detection work.
[0041] It is further explained that the transmission cooperation between the above-mentioned screw and ball nut group is a high-precision, high-efficiency sliding spiral transmission cooperation. A certain number of balls are installed in the threaded raceways of the screw and the ball nut. When the screw rotates, the balls roll in the raceways, driving the ball nut to move along the axis of the screw. The specific structure is not the main innovation of the present invention and will not be elaborated on here.
[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure and are not limiting. Although the present disclosure has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present disclosure may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present disclosure, and all of these should be included in the scope of the claims of the present disclosure.
