Description

Technical Field

[0002] In modern road and bridge construction, highway bridges and viaducts often rely on piers as supports, with the deck and other structural loads transferred to the piers via cap beams. To improve construction efficiency and reduce overhead working time during the current cap beam construction process for high piers, a holistic construction process for the cap beam support has emerged.

In actual application, construction personnel found that the integrated lifting device had some obvious defects, including that its adjustment legs were connected with fixed flanges, which made span adjustment difficult and took up a long time for the construction of the lifting equipment. Based on the above defects, the actual lifting construction application effect of the comprehensive lifting device is not ideal. Therefore, it is necessary to comprehensively improve and optimize these defects to provide an installation and disassembly device that is more suitable for the overall lifting construction of the cap beam support.

DETAILED DESCRIPTION

[0016] Example:

[0017] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0018] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0019] As attached Figure 1-5As shown, a track gauge automatic control system for a cap beam support construction device of this embodiment includes a controller and a cap beam support hoisting device; the controller is communicatively connected to the cap beam support hoisting device, and is used to input settings and or control instructions to manipulate the cap beam support hoisting device for detection, debugging and working operation; the cap beam support hoisting device includes a truss body 1, a slide rail frame 2, an intelligent power module 3, a distance measuring mechanism and a track adjustment drive mechanism; a distance adjustment track structure is provided on the load-bearing beam 4 of the truss body 1, and the intelligent power module 3 is installed at both ends of the load-bearing beam 4 through the slide rail frame 2; the distance measuring mechanism is used to measure the relative distance of the intelligent power module 3, and the track adjustment drive mechanism is used to drive the track adjustment movement of the slide rail frame 2 and the intelligent power module 3 on the distance adjustment track structure.

[0020] In view of the defects of the existing comprehensive lifting device for cap beam support construction, the present invention designs an automatic track gauge control system in a targeted manner. After the cap beam support lifting device is lifted, the relative track distance between the power modules is automatically adjusted by the control drive system, thereby improving the debugging efficiency of the comprehensive lifting device for cap beam support construction and saving debugging time. During the debugging process, feedback control is performed through the detection structure including the distance measuring mechanism to ensure the stability and accuracy of the track adjustment control, which can better meet the actual construction application requirements of the overall lifting of the cap beam support.

[0021] For details, please refer to the attached Figure 5 As shown, the distance measuring mechanism in this embodiment includes at least one distance measuring sensor 5 installed on the load-bearing crossbeam 4, and a distance measuring reflector 6 is set on the slide rail frame 2 corresponding to the distance measuring sensor 5. The relative distance of the intelligent power module 3 is measured by the distance measuring sensor 5 and the distance measuring reflector 6. After the distance-adjustable track structure is installed in place, the cap beam support hoisting device can be started and set for track gauge adjustment through the controller. The detection signal is first sent through the distance measuring sensor 5, and the reflected signal is received after being reflected by the distance measuring reflector 6. The relative distance between the slide rail frame 2 and the intelligent power module 3 thereon relative to the distance measuring sensor 5 is calculated by the time difference between the sending and receiving of the detection signal and the reflected signal. In this embodiment, the distance measuring sensor 5 is fixedly installed on the load-bearing crossbeam 4 and can be regarded as a measurement reference point. The distance measuring reflector 6 moves with the slide rail frame 2. Therefore, by measuring the relative distance between the two, the relative distance of the intelligent power module 3 can be calculated, thereby realizing the measurement and adjustment of the track gauge.

[0022] As a feasible implementation method, see the attached Figure 4As shown, the track adjustment drive mechanism of this embodiment is a screw drive mechanism, which includes a drive motor assembly 7, a track adjustment screw 8 and a screw slider 9. The drive motor assembly 7 is engaged with the track adjustment screw 8 to drive the screw slider 9 to slide on the track adjustment screw 8. After the cap beam support hoisting device is installed in place on the pitch adjustment track structure, the outward protruding portion of the screw slider 9 abuts against the cap beam support hoisting device, and the track gauge is adjusted by driving the screw slider 9 to slide on the track adjustment screw 8, driving the cap beam support hoisting device to move on the pitch adjustment track structure.

[0023] See attached Figure 3 As shown, in order to improve the load capacity and structural stability, this embodiment is composed of a double load-bearing beam structure consisting of two load-bearing beams 4. The inner width of the slide rail frame 2 is adapted to the width of the double load-bearing beam structure. During hoisting and assembly, the truss body 1 is first installed and fixed, and then the slide rail frame 2 is hoisted onto the double load-bearing beam structure. In order to facilitate the hoisting of the slide rail frame 2, in this embodiment, the screw drive mechanism is telescopically arranged on the load-bearing beam 4 relative to the direction of the slide rail frame 2. When the slide rail frame 2 is hoisted, the screw drive mechanism is first retracted and stored inside the load-bearing beam 4 to avoid forming an obstacle to the hoisting of the slide rail frame 2. After the slide rail frame 2 is hoisted into place, the screw drive mechanism is extended and reset to serve as the track adjustment drive power mechanism of the slide rail frame 2 to adjust the track gauge of the intelligent power module 3.

[0024] In another embodiment, the slide rail frame 2 includes a track adjusting plate, and the track adjusting plate is arranged on the slide rail frame 2 to open and close relative to the screw drive mechanism. Specifically, during the assembly process of the slide rail frame 2, the track adjusting plate is in an open state to avoid the assembly process being obstructed by the screw drive mechanism. After the slide rail frame 2 is hoisted into place, the track adjusting plate is closed so that the screw drive mechanism can normally drive the movement of the slide rail frame 2. The open state of the track adjusting plate here means that the outward protruding portion of the screw slider 9 cannot abut and act on the slide rail frame 2, so that the slide rail frame 2 can be normally assembled to the load-bearing beam 4; on the contrary, the closed state of the track adjusting plate means that the outward protruding portion of the screw slider 9 can abut and act on the slide rail frame 2, so that the screw drive mechanism can serve as the track adjustment drive power mechanism of the slide rail frame 2 to adjust the track gauge of the intelligent power module 3.

[0025] In a preferred embodiment, a calibration mechanism is further provided between the slide rail frame 2 and the load-bearing beam 4 for detecting the relative posture of the slide rail frame 2 and the load-bearing beam 4. It is feasible that the calibration mechanism includes a number of signal detectors provided on the slide rail frame 2 and / or the load-bearing beam 4. For example, one or a group of signal transmitters are provided on the slide rail frame 2, and one or a group of signal receivers are correspondingly provided on the load-bearing beam 4, and relative posture detection is performed before the cap beam support hoisting device performs track gauge adjustment. Specifically, since the signal transmitter and the signal receiver are provided in correspondence, that is, only when the cap beam support hoisting device and the load-bearing beam 4 are assembled in place and the relative posture of the two is within a reasonable error range set, the signal of the signal transmitter can be detected and received by the signal receiver, thereby judging whether the cap beam support hoisting device is installed in place during automatic track adjustment. If it is installed in place, the next step of automatic track gauge adjustment can be performed. If it is not installed in place, an alarm can be issued to remind correction to ensure the stability and accuracy of track adjustment control.

[0026] See attached Figure 3 As shown, the distance-adjusting track structure of this embodiment includes at least two distance-adjusting tracks 10, and a track groove 11 adapted to the distance-adjusting track 10 is opened on the slide rail frame 2. After the slide rail frame 2 is assembled to the load-bearing beam 4, at least two distance-adjusting tracks 10 are located in the track groove 11. Based on the relative restriction effect of the distance-adjusting track 10 and the track groove 11, the slide rail frame 2 is guided and positioned so that it slides intelligently along the track direction to further improve the stability of the track adjustment control.

[0027] As described above, the cap beam support hoisting device of the present invention is a device used for the overall hoisting construction of the cap beam support, and has high requirements for the load-bearing load of the device. The main support structures such as the truss body 1 and the slide rail frame 2 are made of steel materials. The support structure itself is heavy and needs to slide relative to each other during the track gauge adjustment process. In order to reduce the sliding resistance during track adjustment and make the track adjustment smoother, in this embodiment, a track adjustment pulley 12 is provided on the slide rail frame 2 or the load-bearing beam 4. The preferred embodiment is to provide a wheel drive mechanism 13 on the slide rail frame 2 or the load-bearing beam 4, and the wheel drive mechanism 13 drives the track adjustment pulley 12 to extend or be accommodated inside the slide rail frame 2 or the load-bearing beam 4. During the track gauge adjustment process, the operation of the wheel drive mechanism 13 causes the track adjustment pulley 12 to extend to support the slide rail frame 2, thereby facilitating the relative movement track adjustment of the slide rail frame 2. After the track adjustment is completed, the track adjustment pulley 12 is retracted into the inside of the slide rail frame 2 through the operation of the wheel drive mechanism 13, thereby increasing the relative sliding resistance between the slide rail frame 2 and the distance adjustment track 10, so that the cap beam support hoisting device can be stably fixed in a predetermined position. Preferably, a limiting mechanism is provided between the slide rail frame 2 and the load-bearing crossbeam 4 for limiting and fixing the slide rail frame 2. Specifically, the limiting mechanism is a limiting bolt 14 provided on the slide rail frame 2. After the track gauge of the cap beam support hoisting device is adjusted into place, the slide rail frame 2 and the load-bearing crossbeam 4 are fixedly connected together by the limiting bolt 14 to achieve track gauge fixation.

[0028] The above description is merely an explanation of the preferred embodiments of the present invention and should not be construed as limiting the claims. The present invention is not limited to the above embodiments, and variations in the specific structure are permitted. In short, all variations made within the scope of the independent claims of the present invention are also within the scope of protection of the present invention.
