Description

Technical Field

[0001] This utility model relates to the field of power equipment installation technology, specifically to an anti-tilt support device for inverted HGIS equipment. Background Technology

[0002] The HGIS equipment inverted installation method involves gradually lifting and installing the equipment after it has been inverted as a whole. This method offers advantages such as reducing high-altitude work and lowering construction costs. During installation, a crane is used to lift the HGIS equipment to the top of the pre-embedded base, adjust its position, and then install a support frame for fixation. Hydraulic jacking is used to adjust the tilt angle. However, the existing installation method has the following drawbacks:

[0003] (1) Insufficient stability of traditional supports: When using rigid supports to directly support the equipment, they cannot adapt to the center of gravity shift of the HGIS equipment (the shift can reach ±30mm). During the hydraulic lifting process, the equipment is prone to tilting due to unilateral force (the tilt angle may exceed 5°).

[0004] (2) Failure of dynamic control of wind cable: Conventional wind cable fixing method is effective in static conditions, but it requires frequent adjustment during dynamic jacking (it needs to be re-fixed every 100mm of jacking), and is affected by wind force (the support force decreases by 40% when the wind speed is ≥8m / s), making it difficult to ensure the verticality of the equipment.

[0005] (3) Insufficient adjustment accuracy: Although traditional screw-type support devices can provide safety support, manual adjustment is inefficient (single adjustment takes more than 15 minutes) and cannot achieve multi-support point coordinated leveling.

[0006] The above-mentioned shortcomings make it difficult to meet the high-precision requirements of modern power equipment installation. These technical deficiencies severely restrict the safety and construction efficiency of the HGIS equipment inversion process. Utility Model Content

[0007] To address the aforementioned problems, this utility model provides an anti-tilt support device for inverted HGIS equipment.

[0008] This utility model is achieved through the following technical solution:

[0009] This application provides an anti-tilt support device for inverted HGIS equipment, the technical solution of which is as follows: it includes a movable support frame, with support columns fixed around the movable support frame, hydraulic support legs provided on the upper part of the support columns, and ball joint supports for supporting the base of the HGIS equipment movably connected to the top of multiple hydraulic support legs. A dual-axis tilt sensor is provided at the lower part of the ball joint support, and the dual-axis tilt sensor is controlled and connected through a hydraulic control system that controls the hydraulic support legs.

[0010] Furthermore, this application also proposes that the base is provided with bolt hole groups around its perimeter for connection with the ball joint support, each bolt hole group including four bolt holes, and the bolt holes and the bolts fixing the ball joint support have an adjustment gap of 5-10mm.

[0011] Furthermore, this application also proposes that the hydraulic control system includes a hydraulic station installed on the upper part of the mobile support frame, and a hydraulic pump, a controller, and a solenoid directional valve are provided on the upper part of the hydraulic station. The controller is electrically connected to multiple dual-axis tilt sensors and multiple solenoid directional valves of the hydraulic station. The hydraulic pump is controlled to be connected to multiple solenoid directional valves and hydraulic support legs through oil pipes.

[0012] Furthermore, this application also proposes that the base of the HGIS equipment is lifted and moved above a predetermined pre-embedded base by a movable support frame, and the pre-embedded base is supported and fixed by the upper support frame.

[0013] Furthermore, this application also proposes that the top of the support frame provides adjustable support to the base via adjusting pads.

[0014] Furthermore, this application also proposes that the size of the movable support frame is smaller than the connection size of the four pre-embedded bases at the bottom of the base.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0023] like Figure 1 As shown, this application proposes an anti-tilt support device for inverted HGIS equipment, including a movable support frame, with support columns fixed around the movable support frame, hydraulic support legs provided on the upper part of the support columns, and ball joint supports for supporting the base of the HGIS equipment movably connected to the top of multiple hydraulic support legs. A dual-axis tilt sensor is provided at the lower part of the ball joint support, and the dual-axis tilt sensor is controlled and connected through a hydraulic control system that controls the hydraulic support legs.

[0024] The mobile support frame can be a welded steel platform with casters at the bottom. Connections between the support columns and the mobile support frame include welding, bolting, or plug-in fixing. The hydraulic support legs can use single-rod double-acting hydraulic cylinders with a stroke range typically ±200mm and a single-leg load capacity ≥500kN. The ball joint support includes an upper hinge plate and a lower hinge plate, with a spherical bearing between them, allowing a deflection angle of ±5°. The dual-axis tilt sensor has a measurement accuracy of ±0.1° and a sampling frequency of not less than 10Hz. The hydraulic control system can use a PLC controller, achieving closed-loop control through a PID algorithm.

[0025] This technical solution solves the problem of traditional rigid supports being unable to adapt to the center of gravity shift of HGIS equipment through the synergistic effect of ball joint supports and dual-axis tilt sensors. Specifically, when the equipment tilts during the lifting process, the dual-axis tilt sensors detect the tilt angle in real time and transmit the signal to the hydraulic control system. The system then automatically levels the equipment by adjusting the extension and retraction of each hydraulic support leg. Compared with existing technologies, this device can maintain the verticality of the equipment during dynamic lifting, avoiding frequent manual adjustments and is unaffected by wind. The ball joint support design allows the equipment to deflect freely within a certain range, effectively dispersing local stress and preventing deformation of the support structure due to unilateral force.

[0026] Furthermore, this application also proposes that the base is provided with bolt hole groups around its perimeter for connection with the ball joint support, each bolt hole group including four bolt holes, and the bolt holes and the bolts fixing the ball joint support have an adjustment gap of 5-10mm.

[0027] The four bolt holes in the bolt hole group are arranged in a rectangular array, with the hole spacing determined according to the flange size of the ball joint support. The adjustment gap is achieved by enlarging the bolt hole diameter, specifically by enlarging the standard M20 bolt holes to Φ25-Φ30mm. This technical solution, by setting up a bolt connection structure with an adjustable gap, solves the problem of installation misalignment caused by center of gravity shift during the inversion of HGIS equipment. Specifically, when the equipment is lifted, after the dual-axis tilt sensor detects the tilt, the hydraulic support legs dynamically level it. At this time, the relative displacement between the ball joint support and the base can be generated through the bolt gap, thereby compensating for the equipment's center of gravity shift. Compared with existing technologies, this structure retains the reliability of bolt connections while avoiding stress concentration caused by rigid fixing, enabling the equipment to achieve adaptive leveling within a ±30mm offset range. Furthermore, the 5-10mm adjustment gap range has been verified through actual testing, meeting the leveling requirements without affecting the overall rigidity of the connection structure.

[0028] Furthermore, this application also proposes that the hydraulic control system includes a hydraulic station installed on the upper part of the mobile support frame, and a hydraulic pump, a controller, and a solenoid directional valve are provided on the upper part of the hydraulic station. The controller is electrically connected to multiple dual-axis tilt sensors and multiple solenoid directional valves of the hydraulic station. The hydraulic pump is controlled to be connected to multiple solenoid directional valves and hydraulic support legs through oil pipes.

[0029] The hydraulic power unit can adopt a split-type structure, which allows the hydraulic pump and oil tank to be arranged separately to reduce the impact of vibration. The electromagnetic directional valve is preferably a three-position four-way type with a mid-position unloading function, which can reduce system energy consumption in non-adjusting states. The oil piping uses multi-layer steel wire braided hydraulic hoses, with a working pressure of not less than 31.5 MPa. The controller can be a PLC or a dedicated hydraulic controller, with a sampling frequency of not less than 10Hz, and equipped with a CAN bus or RS485 communication interface. A signal conditioning module can be added between the dual-axis tilt sensor and the controller to filter and amplify the raw signal.

[0030] This technical solution achieves multi-point coordinated leveling through an integrated hydraulic control system. Dual-axis tilt sensors monitor the equipment's tilt status in real time, and the controller dynamically adjusts the opening of each solenoid directional valve based on sensor data, precisely supplying oil to the corresponding hydraulic support legs via hydraulic pumps. Compared to traditional screw adjustment methods, this system achieves millimeter-level leveling accuracy, a response time of less than 3 seconds, and automatically compensates for dynamic interference such as wind. The parallel oil circuit design of the solenoid directional valves ensures independent controllability of each support leg; when tilting occurs on one side, the system can adjust only the tilted support leg without affecting other support units. The centralized layout of the hydraulic station facilitates maintenance and repair.

[0031] Furthermore, this application also proposes that the base of the HGIS equipment is lifted and moved above a predetermined pre-embedded base by a movable support frame, and the pre-embedded base is supported and fixed by the upper support frame.

[0032] Specifically, the mobile support frame uses hydraulic support legs to lift the HGIS equipment base above the pre-embedded base. The pre-embedded base serves as a permanent support structure, with the support frame on top supporting and securing the equipment base. The support frame and the pre-embedded base are rigidly connected to ensure support stability. As a preferred embodiment, the support frame can be a welded structure made of I-beams or H-beams.

[0033] Therefore, this technical solution solves the problem of insufficient stability of traditional supports during equipment transfer by utilizing the synergistic effect of the mobile support frame and the pre-embedded base. The mobile support frame provides precise vertical lifting, while the pre-embedded base provides final rigid support; together, they achieve a seamless transition of the equipment from temporary to permanent support. Compared with existing technologies, this solution avoids the instability caused by wind cable adjustments. The rigid support structure of the pre-embedded base provides higher support rigidity for the equipment during the final positioning stage, effectively controlling positional deviation during installation.

[0034] Furthermore, this application also proposes that the top of the support frame provides adjustable support to the base via adjusting pads.

[0035] The adjusting pad is made of two interlocking high-strength alloy steel wedge plates. Thickness adjustment is achieved by adjusting the different positions of the two wedge plates, and they can be stacked. The upper surface of the pad is machined with anti-slip texture (texture depth 0.5-1mm), and the lower surface has a positioning boss that fits into the groove on the top of the support frame. The interlocking wedge plates achieve millimeter-level precise leveling of the support frame, ensuring that the base and the HGIS equipment above are in a horizontal position, with a levelness deviation controlled within 0.3°.

[0036] Furthermore, this application also proposes that the size of the movable support frame is smaller than the connection size of the four pre-embedded bases at the bottom of the base.

[0037] Specifically, when the HGIS equipment is lifted to the predetermined height, the mobile support frame can complete its positioning without contacting the pre-embedded base, avoiding equipment displacement caused by structural collisions. Compared with existing technologies, this size design ensures both the stability of the support system and the freedom of vertical movement of the equipment, making it particularly suitable for substation construction environments with limited space. In practice, the relative position between the support frame and the pre-embedded base can be monitored in real time using a laser rangefinder to ensure that a safe distance is always maintained.

[0038] The implementation principle of an anti-tilt support device for inverted HGIS equipment according to an embodiment of this application is as follows:

[0039] First, the mobile support frame 1 is towed to the center of the four pre-embedded bases 11 using a tractor. Then, a crane is used to lift the inverted HGIS equipment 13 and the lower base 14 onto the four hydraulic support legs 3 of the mobile support frame 1. The ball joint supports 4 on the upper part of the four hydraulic support legs 3 are connected to the bolt hole groups 15 of the corresponding bases 14 using bolts. Next, the electromagnetic reversing valve 9 of the hydraulic control system is operated to lift the four hydraulic support legs 3 to a predetermined height. This predetermined height is monitored by a laser rangefinder. The height between the pre-embedded bases 11 and the bases 14 is 1-2 cm higher than the height of the support frame 10. At the same time, during the lifting process, the tilt angle is detected in real time by a dual-axis tilt sensor and the signal is transmitted to the hydraulic control system. The system automatically levels itself by adjusting the extension and retraction of each hydraulic support leg to ensure the flatness of the HGIS equipment 13 and the base 14 and prevent them from tilting.

[0040] Next, the support frame 10 is fixed on the upper part of the pre-embedded base 11. Then, the adjusting shim 12 is placed into the gap between the top of the support frame 10 and the base 14. The positions of the two wedge blocks of the adjusting shim 12 are adjusted so that the adjusting shim 12 fills the entire gap thickness. The electromagnetic reversing valve 9 of the hydraulic control system is operated to change the direction of the oil circuit to realize the retraction of the hydraulic support leg 3, thereby realizing the permanent support conversion of the entire support frame 10. After the support frame 10 is supported, it can be welded for reinforcement. After fixing, the mobile support frame is pulled out by a tractor to realize the installation of the next HGIS equipment 13.
