Description

Technical Field

[0001] This utility model relates to the field of continuous beam hanging basket construction technology, and more specifically, to a hanging basket traveling device for continuous beams. Background Technology

[0002] In bridge cantilever construction, the synchronicity and stability of the formwork's movement directly affect construction efficiency and structural safety. Traditional formwork systems often employ a single high-power hydraulic jack drive or a mechanical chain synchronization scheme, which suffers from technical bottlenecks such as insufficient synchronization accuracy, poor fault tolerance, and a limited range of control strategies.

[0003] Hydraulic systems are susceptible to displacement deviations during multi-hydraulic jacking operations due to fluctuations in oil pressure, pipeline delays, and mechanical wear. This displacement can cause the formwork to shift or even jam, potentially leading to formwork overturning accidents.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Example 1

[0028] This embodiment provides a continuous beam hanging basket traveling device. Figure 1 This is a schematic diagram of the overall assembly of the continuous beam hanging basket traveling device according to an embodiment of this utility model, as shown below. Figure 1 As shown, the hanging basket includes a truss mechanism 100, which consists of two trusses symmetrically distributed on the left and right sides. The continuous beam hanging basket traveling device includes a hydraulic jacking device 200.

[0029] Specifically, the hydraulic jacking device 200 consists of two sets of hydraulic jacking mechanisms, which are respectively located in the middle and tail of the bottom chord 110 of the truss mechanism 100. In particular, the two sets of hydraulic jacking mechanisms are respectively located in the middle and tail of the bottom chord 110 of the truss mechanism 100, so that the hanging basket is subjected to more uniform force, thereby reducing the risk of overturning accidents.

[0030] In this embodiment, the traditional centralized single-point hydraulic power source is divided into multiple independently controlled small hydraulic cylinders. Each hydraulic jacking mechanism consists of a front fulcrum 210, a propulsion mechanism 220, and a main hydraulic cylinder 230. Each main hydraulic cylinder 230 is connected in parallel to a hydraulic oil pump 300 via a high-pressure oil pipe, and the hydraulic oil pump 300 supplies oil to each main hydraulic cylinder 230 synchronously. A hydraulic jacking stroke sensor 250 is provided on the side of each main hydraulic cylinder 230 to monitor the stroke of the main hydraulic cylinder 230. The front fulcrum 210 and the propulsion mechanism 220 are both slidably fitted at the bottom end of the bottom chord 110 of the truss mechanism 100. In some embodiments, the bottom chord 110 of the truss mechanism 100 is an I-beam, and the front fulcrum 210 and the propulsion mechanism 220 are both slidably fitted in the grooves on both sides of the I-beam.

[0031] The fixed end of the main hydraulic cylinder 230 is connected to the propulsion mechanism 220, and the output end of the main hydraulic cylinder 230 is connected to the front support point 210. The extension and retraction of the main hydraulic cylinder 230 drives the relative movement between the tightening mechanism and the bridge.

[0032] A laser displacement sensor is provided between the two bottom chords 110 of the truss mechanism 100 to monitor the displacement between the two bottom chords 110 of the truss mechanism 100; in some embodiments, the laser displacement sensor is located at the inner side of the beginning and end of the bottom chords 110 of the truss mechanism 100 to realize displacement monitoring at the corresponding position.

[0033] The laser displacement sensor, hydraulic jack stroke sensor 250, and hydraulic oil pump 300 are all electrically connected to the controller. In some embodiments, the laser displacement sensor monitors the displacement between the two bottom chords 110 of the truss mechanism 100 in real time. The controller receives and displays the displacement information. At this time, the operator manually controls the oil supply of each high-pressure oil pipe of the hydraulic oil pump 300 to achieve synchronization of each main hydraulic cylinder 230. Simultaneously, the controller monitors the stroke of the main hydraulic cylinder 230 in real time and sends it to the controller for display. The controller can be a human-machine interface screen. In other embodiments, the controller receives and identifies the displacement information, adjusts the oil quantity of each main hydraulic cylinder 230 according to the identification result, and performs dynamic compensation for each main hydraulic cylinder 230 to achieve automatic synchronization.

[0034] In summary, this embodiment uses a hydraulic jacking stroke sensor 250 to monitor the stroke of the main hydraulic cylinder 230 in real time, a laser displacement sensor to monitor the displacement between the two bottom chords 110 of the truss mechanism 100, and adjusts the action of each hydraulic jacking mechanism by controlling and adjusting the oil supply, which can significantly improve the synchronization of the hanging basket's movement.

[0035] Example 2

[0036] This embodiment provides further explanation of the hydraulic jacking mechanism based on the technical solution provided in Embodiment 1:

[0037] In this embodiment, see Figure 2 As shown, each hydraulic jacking mechanism also includes a group of auxiliary hydraulic cylinders 240 located on the side of the main hydraulic cylinder 230; the group of auxiliary hydraulic cylinders 240 consists of several auxiliary hydraulic cylinders 240 and is connected between the front fulcrum 210 and the pushing mechanism, so as to finely adjust the displacement deviation under the control of the controller, compensate for the synchronization error that may occur in the main hydraulic cylinder 230, or maintain the continuous operation of the hydraulic jacking mechanism in the event of a failure of the main hydraulic cylinder 230.

[0038] Specifically, the auxiliary hydraulic cylinder group 240 is connected to the hydraulic oil pump 300 through an independent oil circuit, and each of the independent oil circuits is equipped with a proportional valve; in particular, the configuration of the independent oil circuits and proportional valves enables the auxiliary hydraulic cylinder group 240 to flexibly and accurately adjust the flow rate.

[0039] The auxiliary hydraulic cylinder group 240 consists of two auxiliary hydraulic cylinders 240, which are respectively located on both sides of the main hydraulic cylinder 230. Specifically, the two auxiliary hydraulic cylinders 240 are symmetrically located on both sides of the main hydraulic cylinder 230, which can evenly adjust the displacement on both sides to ensure that the basket is subjected to balanced force.

[0043] A first connecting pin 213 is laterally provided at the front end of the first installation gap. The front ends of the main hydraulic cylinder 230 and the auxiliary hydraulic cylinder 240 are connected to the first connecting pin 213. In this embodiment, the hydraulic cylinder is firmly connected to the front support point 210 and the propulsion mechanism 220 by the connecting pin, which can ensure the stability of power transmission, avoid loosening or displacement, ensure the reliability of the hydraulic jacking mechanism during operation, and reduce failures caused by connection problems.

A second connecting pin 222 is laterally provided at the front end of the second installation gap. The rear ends of the main hydraulic cylinder 230 and the auxiliary hydraulic cylinder 240 are connected to the second connecting pin 222.

[0045] A plurality of stiffening plates are arranged longitudinally at intervals within the first installation gap. The stiffening plates within the front support 210 are sleeved on the outer front end of the main hydraulic cylinder 230 and the auxiliary hydraulic cylinder 240, which can effectively strengthen the structural strength at the first installation gap, reduce the local deformation of the first installation gap when the main hydraulic cylinder 230 is working, and improve the stability of the connection position.

[0046] The outer side of the front support point 210 wall panel is provided with several longitudinally spaced stiffening plates; the outer side of the pushing mechanism wall panel 221 is provided with several longitudinally spaced pushing mechanism stiffening plates 223; the outer stiffening plates on the outer side of the front support point 210 wall panel and the stiffening plates on the pushing mechanism wall panel 221 can enhance the lateral stiffness of the wall panel, prevent bending or twisting under force, ensure the structural stability of the entire jacking mechanism during operation, and avoid affecting the walking accuracy of the hanging basket due to wall panel deformation.

[0047] The front support point 210 also includes a front support point 210 horizontal plate disposed above the stiffening plate of the front support point 210. The front support point 210 horizontal plate is provided with a first limiting mechanism 219 that cooperates with the lower end of the bottom chord 110 of the truss mechanism 100. The pushing mechanism also includes a pushing mechanism connecting plate 225 disposed above the pushing mechanism stiffening plate 223. The pushing mechanism connecting plate 225 is provided with a second limiting mechanism 226 that cooperates with the lower end of the bottom chord 110 of the truss mechanism 100. In this embodiment, the first limiting mechanism 219 and the second limiting mechanism 226 are sliders that slide in cooperation with the grooves on both sides of the I-beam.

[0048] A third connecting pin is laterally arranged in the first installation gap, and a first pawl 217 is provided on the third connecting pin. A fourth connecting pin is laterally arranged in the second installation gap, and a second pawl 224 is provided on the fourth connecting pin. The lower end of the bottom chord 110 of the truss mechanism 100 has several slots spaced longitudinally along its lower end, which engage with the first pawl 217 and the second pawl 224. These slots consist of a groove at the lower end of the bottom chord 110 and slots spaced apart within the groove. Specifically, the first pawl 217 and the second pawl 224 engage with the slots at the lower end of the bottom chord 110, automatically locking the bottom chord 110 when the transplanting hydraulic cylinder lifts a section, thus achieving automatic locking and enabling the basket to move steadily and slowly, ensuring the accuracy and stability of the basket's movement.
