Description

Technical Field

[0001] This invention relates to the field of bridge construction equipment technology, specifically a bridge crash barrier construction operation platform with internal and external protection. Background Technology

[0002] In the construction of bridge crash barriers, work platforms are essential equipment. However, existing bridge crash barrier construction work platforms have some shortcomings.

[0003] On the one hand, traditional work platforms lack stability, especially when performing high-altitude operations. They are unable to effectively resist unbalanced forces caused by construction operations and other factors, which may lead to platform shaking or even safety accidents.

[0004] On the other hand, traditional work platforms are poorly adaptable to different construction conditions and cannot flexibly adjust their structure to meet actual construction needs. For example, during construction, the platform's center of gravity may shift as the weight of personnel, tools, and materials inside the work basket changes, and traditional platforms lack corresponding automatic adjustment mechanisms to maintain balance. Furthermore, existing work platforms are inadequate in terms of protection, failing to provide comprehensive and reliable internal and external protection for construction personnel, thus increasing construction risks.

[0005] Therefore, developing a bridge crash barrier construction platform with good stability, adaptability, and comprehensive protection functions is of great practical significance. Summary of the Invention

[0006] This invention provides a bridge crash barrier construction platform with internal and external protection, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A bridge crash barrier construction platform with internal and external protection includes a base plate with multiple casters at the bottom for easy movement. A construction frame is fixedly connected to one end of the top of the base plate, and a counterweight assembly is installed at the other end. The construction frame is connected to the working mechanism, and the base plate is equipped with a luffing mechanism and an adjustment system. All parts work together to achieve the various functions of the platform.

[0008] The counterweight assembly includes a counterweight cover fixedly mounted on the top of the base plate. Multiple fixed counterweight blocks are located at the top inside the counterweight cover, and an adjustable counterweight block is located at the bottom. A placement seat for supporting and securing the fixed counterweight blocks is fixedly provided on the inner side wall of the counterweight cover, facilitating their placement and fixation. A side opening is provided on the side of the counterweight cover closest to the construction frame. The area of ​​the side opening is larger than the cross-section of the adjustable counterweight block, allowing the adjustable counterweight block to be moved out of the side opening for easy operation.

[0009] The luffing mechanism includes two linear guide rails fixedly mounted on the top of the base plate. A sliding base plate is slidably connected to the top of both linear guide rails, and an adjustable weight is fixedly mounted on the top of the sliding base plate. The position of the adjustable weight can be changed through the cooperation of the linear guide rails and the sliding base plate.

[0010] The working mechanism includes a lifting platform slidably connected to the other side of the construction frame. A construction basket is fixedly connected to the outside of the lifting platform, and a lifting drive mechanism is connected to the lifting platform. The construction frame is an inverted U-shaped structure, with a curved panel fixedly installed inside. The lifting drive mechanism includes a lifting drive motor fixedly installed at the top of the curved panel. A winding wheel is fixedly connected to the output shaft of the lifting drive motor, and a lifting rope is wound around the outside of the winding wheel. A second guide seat is fixedly installed at the top of the construction frame, and a second guide wheel is installed on the second guide seat. The lifting rope passes around the second guide wheel and is fixedly connected to the lifting platform. The lifting drive motor drives the winding wheel to rotate, realizing the winding and unwinding of the lifting rope, thereby driving the lifting platform and the construction basket to rise and fall.

[0011] The adjustment system includes a passive traction mechanism connected to the sliding base plate and an active traction component mounted on the base plate. The passive traction mechanism includes a first guide seat fixedly mounted on the base plate, with a first guide wheel on the first guide seat. A curved guide groove is fixedly mounted on the top of the curved panel. A traction rope is fixedly mounted on the top of the lifting seat. A traction seat is fixedly connected to the side of the sliding base plate closest to the construction frame. The traction rope passes around the curved guide groove and the first guide wheel and is fixedly connected to the traction seat. A tension sensor is installed at the connection between the traction rope and the traction seat. The tension sensor detects the tension generated by the load on the construction basket. The active traction component includes a hydraulic telescopic rod fixedly mounted on the base plate. The telescopic end of the hydraulic telescopic rod is fixedly connected to the traction seat. The hydraulic telescopic rod drives the sliding base plate to move according to the value of the tension sensor, thereby adjusting the position of the adjustable counterweight to balance the unbalanced force generated by the load change on the construction basket.

[0012] The work platform also includes anti-slip baffles to limit the travel of the sliding base plate, preventing it from moving excessively and detaching from the linear guide rail. The bottom of the construction frame is connected to the base plate via a reinforcing seat, enhancing the stability of the connection between the construction frame and the base plate.

[0013] The present invention has the following advantages: By setting up a counterweight component, especially an adjustable counterweight block that can automatically adjust its position according to the load of the construction basket, the present invention effectively balances the unbalanced forces generated during construction, improves the stability of the work platform, and reduces safety risks; the luffing mechanism and the adjustment system work together to adjust the position of the adjustable counterweight block in real time according to the changes in the load in the construction basket, so that the platform can adapt to different construction conditions and improve construction efficiency.

Detailed Implementation

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0023] Please see Figures 1-6A bridge crash barrier construction platform with internal and external protection includes a base plate 1. Multiple casters 2 are symmetrically arranged at the bottom end of the base plate 1 to facilitate movement and adjustment of the entire device on the bridge deck. A construction frame 3 is fixedly connected to one top end of the base plate 1 via a reinforcing seat 6. The construction frame 3 has an inverted U-shaped structure and spans the bridge crash barrier. A lifting seat 4 is vertically slidably connected to the side of the construction frame 3 away from the base plate. A construction basket 5 for placing personnel and equipment is fixedly connected to the outer side of the lifting seat 4.

[0024] A counterweight assembly is provided at the other end of the top of the base plate 1. This assembly includes a counterweight cover 7 fixed to the top of the base plate. A placement seat 23 is fixedly provided on the inner side wall of the counterweight cover 7 for supporting and placing multiple fixed counterweight blocks 22 to provide a foundation balancing torque. An adjustable counterweight block 9 is provided at the bottom of the counterweight cover 7, and a side opening 8 is provided on the side near the construction frame.

[0025] To achieve dynamic adjustment of the center of gravity, two parallel linear guide rails 11 are fixedly installed at the top of the base plate 1. The tops of the two linear guide rails 11 are slidably connected to a sliding base plate 10, and the adjustable counterweight 9 is fixedly installed at the top of the sliding base plate 10. Since the area of ​​the side opening 8 is larger than the cross-section of the adjustable counterweight 9, the adjustable counterweight 9 can smoothly move out of or retract from the side opening 8 along with the sliding base plate 10.

[0026] A traction seat 12 is fixedly connected to the side of the sliding base plate 10 near the construction frame. An active traction component is fixedly provided on the base plate 1. In this embodiment, the active traction component is a hydraulic telescopic rod 13, the telescopic end of which is fixedly connected to the traction seat 12. In addition, the device is also provided with an anti-detachment baffle 21 to limit the sliding stroke and prevent excessive displacement.

[0027] A curved panel 20 is fixedly installed inside the construction frame 3. The lifting drive mechanism includes a lifting drive motor 16 fixed to the top of the curved panel 20, and a winding wheel is coaxially fixedly connected to its output shaft. A lifting rope 18 is wound around the outside of the winding wheel. The rope passes around the second guide wheel 17 fixed to the second guide seat 25 at the top of the construction frame and is fixedly connected to the lifting seat 4.

[0028] The present invention also includes a passive traction mechanism. This mechanism includes a first guide seat 24 fixed on the base plate and a first guide wheel 14 disposed thereon. A curved guide groove 19 is provided at the top of the curved panel 20. One end of a traction rope 15 is fixed to the top of the lifting seat 4, and the other end passes through the curved guide groove 19 and the first guide wheel 14 before being fixedly connected to the traction seat 12.

[0029] A tension sensor is integrated at the connection between the traction rope 15 and the traction seat 12 to monitor the traction force value in real time.

[0030] The workflow of this embodiment is as follows: When construction personnel, equipment, or materials enter the construction basket 5, the gravity at the cantilever end increases. At this time, the lifting seat 4 generates a pulling force on the traction seat 12 through the traction rope 15. This pulling force is guided by the curved guide groove 19 and the first guide wheel 14 and is directly detected by the tension sensor.

[0031] Active adjustment: The control system determines the degree of deviation of the center of gravity based on the value fed back by the tension sensor. Then, it controls the hydraulic telescopic rod 13 to extend or retract, driving the sliding base plate 10 to move along the linear guide rail 11.

[0032] Center of gravity balance: When the load increases, the hydraulic telescopic rod 13 pushes the adjustable counterweight 9 to move away from the construction frame, increasing the lever arm of the counterweight end; conversely, it retracts.

[0033] Through the combined effect of the passive traction sensing and active hydraulic drive, this device achieves real-time shift of the center of gravity, effectively avoiding the risk of platform overturning due to drastic changes in construction load, and ensuring the safety of bridge crash barrier construction operations.

[0034] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
