Abstract
Description
Technical Field
[0001] This invention belongs to the field of power equipment construction technology, specifically relating to an anti-overturning attitude adjustment and transfer tooling and method under the working condition of a disconnector switch ramp. Background Technology
[0002] Gas-insulated metal-enclosed switchgear (GIS) has been widely used in substation construction due to its compact structure, high reliability, and small footprint. GIS equipment typically uses a metal casing to enclose electrical components and inject insulating gas to form a modular assembly structure. Among them, the disconnecting switch, as an important electrical isolation unit in GIS, plays a key role in system maintenance and safety isolation operations. With the functional adjustments of substation areas, the increased frequency of maintenance and replacement, and the growing demand for equipment deployment in complex scenarios, the on-site transfer of GIS electrical units, especially the column-mounted disconnecting switch body, between different areas within the substation has gradually become an important part of the installation and construction process.
[0003] The main body of a column-mounted disconnect switch is generally a vertical columnar structure, integrating components such as a drive actuator, electrical interface, and vacuum or SF6 insulating cavity. It is heavy and has a high center of gravity. Lifting lugs are usually installed on its outer wall for hoisting. During equipment construction, modification, or maintenance, this type of disconnect switch needs to be transported by tracked vehicles, flatbeds, or specialized handling equipment. However, in substations with ramps or temporarily paved surfaces, the high center of gravity of the equipment poses a significant safety hazard, as the transport equipment is prone to tipping over during ramp operation.
[0004] Currently, common methods for transporting disconnect switches mainly rely on mechanical load-bearing and binding limits to secure the equipment, which can still meet basic stability requirements when operating on level surfaces. However, such transport equipment typically lacks real-time attitude sensing and effective compensation measures for slope conditions. When the equipment travels uphill or downhill with the transport equipment, the disconnect switch body is prone to tilting forward or backward, which can easily lead to overall overturning, making it difficult to guarantee its safety. Therefore, how to implement safe transport under various terrain conditions and maintain the stable posture of the column-mounted disconnect switch body during slope operation is a key technical problem that urgently needs to be solved. Summary of the Invention
[0005] This invention provides an anti-overturning attitude adjustment transport tool and method for disconnecting switches under slope conditions, in order to solve the technical problem that when the column-type disconnecting switch body is transported on a slope or on a road with elevation changes, the equipment has a high center of gravity and is prone to tilting forward or backward with changes in walking posture. Existing transport methods cannot make timely attitude compensation adjustments, thus leading to the risk of overturning of the equipment during transport.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: An anti-tipping attitude adjustment and transfer fixture for disconnecting switches operating on ramps includes a lifting support frame. The disconnecting switch is held and clamped within the lifting support frame by a clamping assembly. A tracked walking mechanism is located at the bottom of the lifting support frame and is hinged to it. Hydraulic cylinders are located at both ends of the lifting support frame, and these cylinders drive the lifting support frame to produce pitch compensation deflection relative to the tracked walking mechanism. The tracked walking mechanism is also equipped with a detection device for detecting its operating attitude. An electrical control box is mounted on the lifting support frame, and the detection device and the two hydraulic cylinders are connected to the control box. The control box receives the detection results from the detection device and controls the two hydraulic cylinders to perform synchronous extension and retraction movements.
[0007] The holding and clamping assembly consists of two holding and clamping plates, which are symmetrically arranged above the hoisting support frame. Each of the two holding and clamping plates has an arc-shaped clamping surface on its opposite side, which corresponds to the arc shape of the upper outer wall of the disconnecting switch. Each of the two holding and clamping plates is fixed to the hoisting support frame on the side facing away from the arc-shaped clamping surface by a drive connecting rod. Guide connecting rods are symmetrically arranged on both sides of the drive connecting rod. A clamping drive cylinder is provided on the hoisting support frame, and the drive connecting rod passes through the hoisting support frame and is connected to the piston rod of the clamping drive cylinder.
[0008] The two ends of the arc-shaped clamping surface are support grooves, and the upper outer wall of the disconnecting switch is provided with lifting lugs corresponding to the support grooves. The support grooves accommodate the lower edges of the four lifting lugs on the outer wall of the disconnecting switch.
[0009] The hoisting support frame has an overall upper forward-extending frame structure. The tracked walking mechanism includes two track components. A hydraulic support mounting frame is fixed at the lower end of the hoisting support frame. The hydraulic support mounting frame has an overall U-shaped frame structure with an open front end. The two track components are symmetrically installed on both sides of the lower end of the hydraulic support mounting frame. The electrical control box is installed on the lower rear side of the hoisting support frame, and the lower end of the electrical control box is vertically fixed on the hoisting support frame.
[0010] The hoisting support frame includes two vertical support members, which are arranged symmetrically on the left and right. The lower ends of the two vertical support members are hinged to the two side beams of the hydraulic support mounting frame. The hoisting support frame also includes a forward extension support arm that extends forward from the upper part of the vertical support members and is vertically connected to the vertical support members. The two vertical support members correspond one-to-one with the two forward extension support arms. The vertical support members are provided with lugs that are hinged to the piston rod end of the hydraulic cylinder.
[0011] The hydraulic support mounting frame has supports on both sides of its upper surface. The cylinder ends of the two hydraulic cylinders are hinged to the supports on both sides of the hydraulic support mounting frame. The upper end of the lifting support frame has lugs on both sides, and the two lugs are symmetrical to each other. The piston rod ends of the two hydraulic cylinders are hinged to the lugs symmetrically arranged on the upper end of the lifting support frame. The lower end of the lifting support frame is hinged to the rear end of the hydraulic support mounting frame.
[0012] The detection device is a tilt sensor, which is fixedly installed on the tracked walking mechanism. It is used to detect the forward and backward tilt of the tracked walking mechanism relative to the horizontal reference in real time during the transportation process, and output the detection data to the electrical control box.
[0013] The tilt sensor monitors the lateral tilt of the tracked walking mechanism relative to the horizontal reference in real time and outputs the monitoring data to the control box. A tilt threshold is preset, and the control box compares the received data with the tilt threshold. When the real-time monitored lateral tilt exceeds the preset tilt threshold, the control box issues an alarm.
[0014] The electrical control box includes an attitude data acquisition module, an attitude adjustment control module, a walking control module, and a display and alarm module; The attitude data acquisition module is used to acquire the attitude signals output by the detection device in real time; The attitude adjustment control module is used to synchronously extend and retract the two hydraulic cylinders based on the attitude signal; the walking control module is used to control the operation of the tracked walking mechanism. The display and alarm module is connected to the attitude data acquisition module. The display and alarm module is used to display the current transport attitude information and issue an alarm when the attitude deviation exceeds a preset threshold.
[0015] A method for adjusting and transporting a disconnector under ramp conditions to prevent overturning includes the following steps: The disconnect switch is fixed to the hoisting support frame by the holding and clamping assembly, so that the disconnect switch is in the initial vertical state, and the initial attitude data of the tracked walking mechanism is collected by the detection device, and the detection device sends the detected initial attitude data to the electrical control box. During the transfer process, the detection device continuously detects the real-time running posture information of the tracked walking mechanism under the slope condition, and outputs the real-time running posture information to the control box. The control box compares the real-time running posture information with the initial posture data and calculates the posture deviation. The electrical control box sends control commands to the two hydraulic cylinders based on the attitude deviation, driving the two hydraulic cylinders to extend and retract synchronously, so that the lifting support frame deflects slightly in the opposite direction of the slope relative to the crawler walking mechanism, so as to keep the disconnecting switch in a vertical state. After the disconnecting switch has been transferred, the electrical control box stops the hydraulic cylinder, thereby stopping the lifting support frame from adjusting its posture and stopping the crawler walking mechanism from moving, thus ending the transfer.
[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention proposes an anti-tipping attitude adjustment and transfer fixture for disconnecting switches operating on ramps. The clamping assembly uses a clamping plate with an arc-shaped clamping surface and a supporting groove, which precisely matches the arc shape of the upper outer wall and the lifting lugs of the disconnecting switch. This achieves a close-fitting clamping and limiting support for the disconnecting switch, completely eliminating the risk of equipment displacement and shaking during transfer and ensuring the reliability of structural fixation. The lifting support frame adopts a frame structure with vertical support members, a forward support arm, and horizontal and diagonal reinforcing members. The hydraulic support mounting frame has a U-shaped frame design. The combination of these two forms a multi-dimensional rigid system, significantly improving the overall load-bearing strength of the fixture. It can stably support the weight of the disconnecting switch and cope with the dynamic loads under ramp conditions.
[0017] Furthermore, the tracked assembly possesses excellent terrain passability, enabling stable movement on slopes and rough surfaces. This solves the problem of traditional wheeled transport equipment slipping and becoming unstable on slopes, providing fundamental adaptability for the transport of disconnect switches. Through the cooperation of hydraulic cylinders and articulated structures, the lifting support frame can be driven to produce pitch compensation deflection. Combined with real-time data interaction between tilt sensors and the electrical control box, the attitude of the disconnect switch can be dynamically adjusted under slope conditions, ensuring it remains vertical at all times. This fundamentally solves the technical challenges of high center of gravity and easy forward or backward tilting and overturning of column-type disconnect switches during slope transport.
[0018] Furthermore, the electrical control box integrates posture data acquisition, adjustment control, walking control, and display and alarm modules, realizing an automated closed loop of detection, analysis, control, and feedback. The posture data acquisition module captures the walking posture in real time, and the posture adjustment control module drives the hydraulic cylinders to move synchronously, completing precise posture compensation without manual intervention, significantly improving transportation efficiency and reliability. The display and alarm module can display transportation posture information in real time and automatically alarm when the posture deviation exceeds a preset threshold; combined with the tilt threshold monitoring logic, it forms a dual safety protection of active adjustment and passive early warning, comprehensively avoiding the risk of overturning.
[0019] This invention provides a method for adjusting the anti-tipping attitude of a disconnecting switch under slope conditions. During the loading stage, the disconnecting switch is fixed to the lifting support frame via a clamping assembly, ensuring the switch is in an initial vertical state. Simultaneously, the initial attitude data of the tracked walking mechanism is collected as reference information. Because the lifting support frame and the tracked walking mechanism are hinged, they can rotate relative to each other under slope conditions. The structural layout provides space for subsequent pitch angle adjustment, facilitating compensation adjustments when the slope changes.
[0020] During transport, the detection device monitors the tracked walking mechanism's posture relative to a horizontal reference in real time and transmits the posture data to the control box. Based on the detection results, the control box drives two hydraulic cylinders to extend and retract synchronously, causing the lifting support frame to deflect at a small angle against the slope around the rear hinge point. This dynamic compensation, which adapts to slope changes, effectively reduces the forward or backward tilting of the disconnect switch caused by the slope's inclination, resulting in relatively small changes in the disconnect switch's posture during transport and helping to reduce the risk of overturning due to posture deviations. Simultaneously, during transport, the two hydraulic cylinders adjust the deflection of the lifting support frame to keep the disconnect switch vertical, thus maintaining its center of gravity stability and improving operational stability on slopes. Once the disconnect switch reaches the target position, the control box stops the hydraulic cylinders' adjustment and halts the tracked walking mechanism's movement, ending the entire transport process under controlled conditions. Through this process, posture detection, compensation adjustment, and walking operation form a synergistic relationship, making the transport action more seamless, reducing manual intervention, and contributing to improved operational safety on slopes.

[0023] To further understand the content of this invention, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.
[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0025] In substations where gas-insulated metal-enclosed switchgear (GIS) and conventional open-type electrical equipment are mixed, the pole-mounted disconnector switch, due to its greater height and higher center of gravity, often needs to be moved or transported during equipment disassembly, replacement, or relocation of the substation area. Substation roads, the area around the structural foundations, and temporary construction access roads often have varying slopes or local elevation differences. When the disconnector switch is transported while suspended or clamped, its structure is highly susceptible to swaying due to the gravitational torque caused by changes in the slope angle. As the slope continues to change, the sway amplitude further amplifies, increasing the risk of collision with surrounding facilities or tipping over.
[0026] Currently, the industry typically reduces attitude deviation by reducing walking speed, frequent stops, and temporary supports. However, these methods are highly dependent on operator experience and often fail to promptly suppress the tilting trend of the disconnect switch when the slope changes rapidly or road conditions are complex. Furthermore, load changes caused by swaying can lead to uneven stress on the lifting parts or equipment connection points, exacerbating operational risks. To address these issues, it is necessary to maintain the disconnect switch's attitude within a suitable range during slope transport, thereby improving on-site operational safety and operational stability.
[0027] like Figure 2 , Figure 3 and Figure 4 As shown, this embodiment provides an anti-overturning attitude adjustment and transfer fixture for disconnecting switches under ramp conditions. It can hold, clamp, and fix the disconnecting switch and adjust its attitude during transfer. The anti-overturning attitude adjustment and transfer fixture includes: a lifting support frame 20, inside which the disconnecting switch 1 is held, clamped, and fixed by a holding and clamping assembly 30; a tracked walking mechanism 10 is provided at the bottom of the lifting support frame 20; the tracked walking mechanism 10 is connected to the lifting support frame 20 by a hinge. Hydraulic cylinders 40 are provided at both ends of the lifting support frame 20, and the two hydraulic cylinders 40 can drive the lifting support frame 20 to produce pitch compensation deflection relative to the tracked walking mechanism 10. The tracked walking mechanism 10 is also equipped with a detection device for detecting the running attitude. An electrical control box 50 is provided on the lifting support frame 20, and the detection device and the two hydraulic cylinders 40 are all connected to the electrical control box 50. The electrical control box 50 is used to receive the detection results from the detection device and control the two hydraulic cylinders 40 to perform synchronous extension and retraction movements.
[0028] Based on the aforementioned anti-overturning attitude adjustment and transfer fixture for disconnecting switches under ramp conditions, this embodiment also proposes an anti-overturning attitude adjustment and transfer method for disconnecting switches under ramp conditions. This transfer method includes four steps: loading and fixing, ramp attitude detection, attitude adjustment execution, and termination of transfer. Figure 1 As shown, the specific process of this transfer method is as follows: Step S1: Fix the disconnect switch 1 to the hoisting support frame 20 via the holding and clamping assembly 30, so that the disconnect switch 1 is in the initial vertical state, and collect the initial attitude data of the tracked walking mechanism 10 through the detection device, and send the detected initial attitude data to the electrical control box 50. Step S2: During the transfer process, the detection device continuously detects the real-time running posture information of the tracked walking mechanism 10 under the slope condition, and outputs the real-time running posture information to the electrical control box 50. The electrical control box 50 compares the real-time running posture information with the initial posture data and calculates the posture deviation. Step S3: The electrical control box 50 sends control commands to the two hydraulic cylinders 40 according to the attitude deviation, driving the two hydraulic cylinders 40 to extend and retract synchronously, so that the lifting support frame 20 deflects slightly in the opposite direction of the slope relative to the crawler walking mechanism 10, so as to keep the disconnecting switch in a vertical state. Step S4: After the disconnecting switch 1 completes the transfer, the electrical control box 50 stops the operation of the hydraulic cylinder 40, so that the hoisting support frame 20 stops the attitude adjustment action and the crawler walking mechanism 10 stops walking, thus ending the transfer.
[0029] In this embodiment, during the loading stage, the disconnect switch 1 is fixed to the lifting support frame 20 via the clamping assembly 30, placing the disconnect switch 1 in a vertical initial state. Simultaneously, the detection device collects the initial attitude data of the tracked walking mechanism 10 as reference information, providing an initial zero point for subsequent anti-overturning attitude adjustment under slope conditions, ensuring the accuracy and continuity of attitude adjustment. Because the lifting support frame 20 and the tracked walking mechanism 10 are hinged, they can rotate relative to each other under slope conditions. The structural arrangement provides space for subsequent pitch angle adjustment, facilitating compensation adjustments when the slope changes.
[0030] During the transfer process, the detection device monitors the real-time running posture information of the tracked walking mechanism 10 relative to the horizontal reference and transmits this information to the electrical control box 50. Based on the comparison between the real-time running posture information and the initial posture data, the electrical control box 50 drives two hydraulic cylinders 40 to extend and retract synchronously, causing the lifting support frame 20 to deflect at a small angle against the slope around the rear hinge point. This dynamic compensation, which adapts to slope changes, effectively reduces the forward or backward tilting of the disconnector switch 1 caused by the slope inclination, resulting in relatively small changes in the posture of the disconnector switch 1 during transfer and helping to reduce the risk of overturning due to posture deviations. Simultaneously, during the transfer process, the two hydraulic cylinders 40 adjust the deflection of the lifting support frame 20 to keep the disconnector switch 1 in a vertical position, thus maintaining a stable center of gravity and improving operational stability during slope travel. When the disconnector switch 1 reaches the target position, the electrical control box 50 stops the adjustment action of the hydraulic cylinders 40 and stops the walking operation of the tracked walking mechanism 10, ending the entire transfer process under controlled conditions. Through the above process, a synergistic relationship is formed between posture detection, compensation adjustment and walking operation, making the transfer action more coherent, thereby reducing human intervention and helping to improve the operational safety in slope environments.
[0031] It should be noted that after the disconnect switch 1 is fixed to the area above the hoisting support frame 20 by the clamping assembly 30, a certain height space must be maintained between the bottom of the disconnect switch 1 and the ground in the fixed state so that it can remain separated from the ground when pitch compensation is performed during ramp travel. At the same time, an appropriate gap should be reserved between the outer periphery of the disconnect switch 1 and the hoisting support frame 20 so that the disconnect switch 1 will not interfere with or collide with the structure of the hoisting support frame 20 when it makes small-angle attitude adjustments with the extension and retraction of the hydraulic cylinder 40. Through the above spatial arrangement, the necessary range of motion for the attitude correction action of the disconnect switch 1 can be provided, reducing the risk of restricted attitude deflection or jamming, and helping to improve the continuity and stability of the transfer action under ramp conditions.
[0032] In a preferred embodiment of the present invention, the detection device is a tilt sensor, which is fixedly mounted on the tracked walking mechanism 10 and is used to detect the forward and backward tilt state of the tracked walking mechanism 10 relative to the horizontal reference in real time during the transfer process, and output the detection data to the electrical control box 50.
[0033] Since the tracked walking mechanism 10 is in direct contact with the ground, its attitude relative to the ground can remain approximately constant on a flat slope, but its pitch tilt relative to the horizontal reference will change with the slope. At this time, the tilt sensor outputs the corresponding real-time running attitude information based on the current tilt state, enabling the control box 50 to grasp the tilt trend in a timely manner and drive the hydraulic cylinder 40 to perform pitch compensation adjustment accordingly.
[0034] The arrangement of the tilt sensors described above makes the attitude adjustment behavior more closely resemble the actual terrain changes, helping to reduce the accumulation of attitude deviations caused by sudden changes in ground height or acceleration and deceleration during driving. During dynamic transfer, the isolating switch 1 can always maintain a near-vertical transfer attitude, thereby reducing the risk of overturning caused by uneven force and center of gravity shift, and also reducing additional manual intervention, thus improving the stability and continuity of the transfer process.
[0035] In another preferred embodiment of the present invention, during the transfer process, the lateral tilt state of the tracked walking mechanism 10 relative to the horizontal reference is monitored in real time by an tilt sensor, and the monitoring data is output to the electrical control box 50. A tilt threshold is preset, and the electrical control box 50 compares the received data with the tilt threshold. When the real-time monitored lateral tilt state exceeds the preset tilt threshold, the electrical control box 50 issues an alarm prompt.
[0036] Lateral attitude deviations can occur due to factors such as ramp turns, uneven tracks, or local elevation differences. Lateral tilt signals can promptly reflect the shift in the equipment's center of gravity relative to the track support surface. When the detected lateral tilt exceeds a preset tilt threshold, the control box 50 issues an alarm, guiding operators to slow down or halt the transfer, thus preventing further lateral instability. This method makes the transfer process more sensitive to changes in lateral attitude, helping to reduce adverse postures of the isolating switch 1 due to abnormal lateral forces, lowering the risk of rollover, and improving transfer stability under ramp and complex terrain conditions.
[0037] In another preferred embodiment of the present invention, the holding and clamping assembly 30 is composed of two holding and clamping plates 31, which are arranged symmetrically on the left and right sides above the hoisting support frame 20. Each of the two clamping plates 31 has an arc-shaped clamping surface 311 facing the upper outer wall of the disconnector switch 1 on one side opposite to it. Each of the two clamping plates 31 is fixed to the hoisting support frame 20 via a drive connecting rod 312 on the side opposite to the arc-shaped clamping surface 311. Guide connecting rods 313 are symmetrically arranged on both sides of the drive connecting rod 312. A clamping drive cylinder 314 is provided on the hoisting support frame 20. The drive connecting rod 312 passes through the hoisting support frame 20 and is connected to the piston rod of the clamping drive cylinder 314. It is used to push the clamping plates 31 along the clamping direction of the arc-shaped clamping surface 311 by the drive connecting rod 312 driven by the clamping drive cylinder 314. The two guide connecting rods 313 are arranged parallel to the drive connecting rod 312 and pass through the hoisting support frame 20. They are used to guide and constrain the movement of the clamping plates 31 in the clamping direction.
[0038] Each of the two holding clamping plates 31 has a supporting groove 315 at its opposite ends of its respective arc-shaped clamping surface 311. The outer wall of the disconnecting switch 1 is provided with four lifting lugs 1-1 corresponding to the supporting grooves 315. The supporting grooves 315 are used to accommodate the lower edges of the four lifting lugs 1-1 on the outer wall of the disconnecting switch 1, so as to support and limit the four lifting lugs 1-1 on the outer wall of the disconnecting switch 1 after the two holding clamping plates 31 clamp the disconnecting switch 1.
[0039] The clamping assembly 30 clamps the upper cylindrical outer wall of the disconnector switch 1 using symmetrically arranged clamping plates 31. When the arc-shaped clamping surface 311 of each clamping plate 31 is in contact with the outer wall of the disconnector switch 1, it forms surface contact. Compared to line or point contact, this surface contact disperses local pressure during clamping and reduces the tendency to slip due to uneven local force. A drive connecting rod 312 and a guide connecting rod 313 arranged parallel to the arc-shaped clamping surface 311 are provided on the side of the clamping plate 31 facing away from it. These two rods are connected to the clamping drive cylinder 314 and the lifting support frame 20, respectively. When the clamping drive cylinder 314 is activated, the movement direction of the clamping plate 31 is constrained by the guide connecting rod 313 along the radial direction of the disconnector switch 1, thereby better controlling the clamping movement path. This helps to limit the attitude of the disconnector switch 1, reduce sway during loading, and provide a stable force base for subsequent pitch adjustment.
[0040] In addition, support grooves 315 are formed at both ends of each arc-shaped clamping surface 311 to accommodate the lower edges of the four lifting lugs 1-1 on the outer wall of the disconnector switch 1. The lifting lugs 1-1 on the outer wall of the disconnector switch 1 are capable of bearing vertical loads. The support grooves 315 provide support for the lifting lugs 1-1, and combined with the limiting effect of the support grooves 315 on the lifting lugs 1-1, the relative sliding of the disconnector switch 1 in the clamping direction and vertical direction can be prevented. Moreover, the four-point support can form a relatively stable spatial limit, so that the upper part of the disconnector switch 1 is more evenly supported and constrained. When the tracked walking mechanism 10 travels on a slope, the deflection range of the disconnector switch 1 relative to the lifting support frame 20 is limited, and lateral and torsional disturbances are also suppressed to a certain extent. Through the above structural arrangement, the swing amplitude of the disconnector switch 1 can be reduced during attitude follow-up adjustment, thereby helping to improve the overall stability and reliability of the operation under slope transportation conditions.
[0041] In another preferred embodiment of the present invention, the tracked walking mechanism 10 includes two track assemblies 11 arranged symmetrically on the left and right sides below the lifting support frame 20. A hydraulic support mounting frame 12 is fixed at the lower end of the lifting support frame 20. The hydraulic support mounting frame 12 is a U-shaped frame structure with an open front end. The two track assemblies 11 are symmetrically installed on both sides of the lower end of the hydraulic support mounting frame 12. An electrical control box 50 is installed on the lower rear side of the lifting support frame 20, and the lower end of the electrical control box 50 is vertically fixed on the lifting support frame 20.
[0042] The tracked walking mechanism 10 employs symmetrically arranged track assemblies 11, which, together with the hydraulic support mounting frame 12 located on them, form an integrated load-bearing foundation. When the two track assemblies 11 contact the ground, they form a large contact area, which reduces the pressure exerted by the equipment's weight on the local ground, thereby reducing the possibility of subsidence or localized slippage in soft ground. Furthermore, the dual-track structure can also distribute lateral loads, resulting in a more balanced lateral force distribution during travel, which is beneficial for maintaining stability.
[0043] Furthermore, the hydraulic support mounting frame 12 has an overall U-shaped frame structure with an open front end. This structure provides space for the travel path in the front opening area, facilitating the equipment to cross road bumps or drive up slopes. At the same time, the hydraulic support mounting frame 12 provides a stable mounting support position for the two hydraulic cylinders 40, allowing the reaction force generated by the hydraulic cylinders 40 during pitch adjustment to be transmitted more directly to the track assemblies 11 on both sides. The adjustment load is shared by the tracks and the ground, making the force on the left and right sides more balanced, thereby helping to reduce lateral sway caused by attitude adjustment.
[0044] In another preferred embodiment of the present invention, each track assembly 11 includes a track, a guide wheel, a drive wheel, and a plurality of load-bearing rollers for supporting the track.
[0045] The drive wheel is connected to the drive motor mounted on the hydraulic support mounting frame 12 for driving the track to move in a circular motion. Two hydraulic cylinders 40 are inclinedly arranged between the hydraulic support mounting frame 12 and the lifting support frame 20. The two hydraulic cylinders 40 are symmetrically arranged. Supports 120 are provided on the upper surfaces of both sides of the hydraulic support mounting frame 12. The cylinder ends of the two hydraulic cylinders 40 are respectively hinged to the supports 120 on both sides of the hydraulic support mounting frame 12. The upper ends of the lifting support frame 20 are provided with lugs 201 on both sides. The two lugs 201 are symmetrically arranged. The piston rod ends of the two hydraulic cylinders 40 are hinged to the lugs 201 symmetrically arranged on the upper end of the lifting support frame 20. The lower end of the lifting support frame 20 is hinged to the rear end of the hydraulic support mounting frame 12.
[0046] Each track assembly 11 is equipped with a guide wheel, a drive wheel, and a load-bearing support roller, providing continuous support for the track along the direction of travel. When in contact with the ground, the track can conform to the terrain over a wider area, helping to reduce localized suspension caused by uneven ground and lowering the possibility of sudden tilting or slippage during travel. Simultaneously, the drive wheel is powered directly by a drive motor mounted on the hydraulic support bracket 12, resulting in a shorter transmission path. This facilitates maintaining lower travel speeds and higher output torque on slopes, making the transport process more controllable.
[0047] Furthermore, the two hydraulic cylinders 40 are arranged at an angle and connected to corresponding positions between the hydraulic support mounting frame 12 and the hoisting support frame 20, respectively. The extension and retraction of the hydraulic cylinders 40 create pitch compensation adjustment. The cylinder body end is hinged to the support 120 of the hydraulic support mounting frame 12, and the piston rod end is hinged to the symmetrically arranged lugs 201 on the hoisting support frame 20. Through this force transmission path, the hoisting support frame 20 can rotate at a small angle around the hinge point between its bottom end and the rear end of the mounting frame. This arrangement helps to distribute the vertical and horizontal thrust during attitude adjustment, making the force state more balanced during the adjustment action, thereby reducing the vibration caused by attitude adjustment. The above structural coordination enables the disconnecting switch 1 to adapt well to changes in road slope during ramp operation and maintain a relatively stable attitude adjustment response.
[0048] It should be noted that the structural form of the track assembly 11 is not limited to the configuration shown in this embodiment. As long as the track still forms continuous contact support with the ground and can be directly installed on the hydraulic support mounting frame 12 to bear the weight of the entire machine, it can be considered an equivalent track structure. For example, the track assembly 11 can be made of steel or rubber tracks, and the number and arrangement of guide wheels, load-bearing rollers, or drive wheels can be adjusted according to the weight level of the transported object and the working environment; the track tensioning method can be mechanical or hydraulic adjustment, and the driving method can be a single-sided independent drive or a center drive structure. The above substitutions only involve engineering changes to the specific structural form of the track assembly 11 and the configuration of the support wheel set, and do not affect its functional positioning as a support component for equipment movement, nor will they change the working method of the two track assemblies 11 being symmetrically installed on the hydraulic support mounting frame 12 and jointly realizing ramp travel and attitude adjustment. Therefore, under the premise of having the same installation position and load-bearing function, any tracked structure can be applied to the tracked walking mechanism 10 of this embodiment.
[0049] Furthermore, the key to the tracked walking mechanism 10 lies in the hydraulic support mounting frame 12. This mounting frame not only serves as the mounting base for the track assembly 11 but also bears the force transmission from the lifting support frame 20, forming the structural core connecting the track assembly 11 and the hydraulic cylinder 40. The hydraulic support mounting frame 12 provides a stable mounting position for the hinged end of the hydraulic cylinder 40 and a structural fulcrum for the hinged bottom end of the lifting support frame 20, enabling pitch compensation adjustment to be performed under stable support conditions. Through this functionally integrated structural arrangement, the tracked walking mechanism 10 not only possesses load-bearing walking capacity but can also cooperate with the lifting support frame 20 to complete attitude adjustment when the slope changes. Thus, it can be seen that the hydraulic support mounting frame 12 in this embodiment undertakes the comprehensive functions of support, connection, and pitch adjustment foundation support, and is an important structural link for realizing slope anti-overturning attitude adjustment.
[0050] In a preferred embodiment of the present invention, the hydraulic support mounting frame 12 includes two side beams 121 and a rear crossbeam 122 connecting the tail ends of the two side beams 121. The two side beams 121 are arranged in parallel on the two track assemblies 11. A hinge seat 123 is provided above the tail ends of the two side beams 121 respectively. The hydraulic support mounting frame 12 is hinged to the bottom end of the lifting support frame 20 through the hinge seat 123. A support 120 is also provided on the side beams 121. The cylinder end of the hydraulic cylinder 40 is hinged to the support 120.
[0051] The hydraulic support mounting frame 12 consists of parallel side beams 121 arranged on the left and right sides and a rear crossbeam 122 connecting the tail ends of the two side beams 121, forming a frame structure with good overall rigidity. On the one hand, the side beams 121 provide a mounting base for the left and right track assemblies 11, and the load from the track contact ground can be transferred to the interior of the structure through the side beams 121; on the other hand, the frame as a whole has a strong load-bearing capacity against the pressure from the superstructure, which can reduce attitude fluctuations caused by local structural deformation.
[0052] A hinge seat 123 corresponding to the bottom end of the hoisting support frame 20 is provided above the tail end of the side beam 121, so that the hoisting support frame 20 can form a clear pitch rotation center around this point. This arrangement helps to perform pitch direction linkage compensation for the disconnecting switch 1 under slope conditions, and the vertical load generated during rotation can be directly transferred to the support frame from the hinge position, reducing unnecessary additional torque.
[0053] Furthermore, the rear half of the side beam 121 is equipped with a support 120 for hinged connection with the cylinder end of the hydraulic cylinder 40. This support is located in front of the hinge seat 123. When the hydraulic cylinder 40 is driven, a clear force transmission path is formed through the support 120, hydraulic cylinder 40, lug 201, and hinge seat 123, allowing the force generated by pitch adjustment to be evenly distributed within the frame structure. This arrangement helps control structural stress differences during adjustment, reduces transient swaying caused by attitude adjustment, and makes pitch compensation of the disconnector switch 1 more stable when traveling on a slope.
[0054] In another preferred embodiment of the present invention, the hoisting support frame 20 is generally a forward-extending frame structure. The hoisting support frame 20 includes two vertical support members 21, which are symmetrically arranged. The lower ends of the two vertical support members 21 are hinged to the side beams 121 of the hydraulic support mounting frame 12. The hoisting support frame 20 also includes forward-extending support arms 22 extending forward from the upper part of the vertical support members 21 and perpendicularly connected to them. A transverse connecting member 23 is provided at the connection point between the two vertical support members 21. The two vertical support members 21 correspond one-to-one with the two forward-extending support arms 22, and a support reinforcement structure is formed between the vertical support members 21 and the forward-extending support arms 22 by oblique reinforcing members 24. The two forward-extending support arms 22 are provided with mounting positions for installing the holding and clamping assembly 30, and the vertical support members 21 are provided with lugs 201 that are hinged to the piston rod end of the hydraulic cylinder 40.
[0055] The lifting support frame 20 adopts an upper forward-extending frame structure. The symmetrically arranged vertical support members 21 serve as the main load-bearing components of the lifting support frame 20. A forward-extending support arm 22, extending forward from its upper part, is equipped with a clamping assembly 30 to support the upper area of the disconnecting switch 1. This arrangement, by placing the clamping assembly 30 at the front end of the forward-extending support arm 22, allows the disconnecting switch 1 to be corrected for posture deviations primarily through small extensions and retractions of the hydraulic cylinder 40 after loading and fixing. The additional bending effect the structure needs to withstand is relatively small, which is beneficial for achieving relatively smooth pitch compensation under slope conditions. Furthermore, the upper forward-extending frame structure of the lifting support frame 20 ensures that the disconnecting switch 1 maintains a reasonable clearance between itself and the ground and the traveling structure during slope movement, thereby reducing the risk of interference or accidental contact and ensuring relatively smooth transfer of the disconnecting switch 1.
[0056] The vertical support members 21 are connected by transverse connecting members 23 to provide lateral stability, and are further reinforced by diagonal reinforcing members 24 to form a triangular reinforcement system with the extended support arm 22, giving the hoisting support frame 20 good bending and torsional stiffness during operation. The lower half of the vertical support members 21 is provided with lugs 201 that are hinged to the piston rod end of the hydraulic cylinder 40, allowing the thrust generated by the hydraulic cylinder 40 during pitch adjustment to act directly on the support frame, and achieving angle compensation adjustment around the hinge point between the bottom of the hoisting support frame 20 and the hydraulic support mounting frame 12. Through the above structural relationships, the structural forces are more balanced during attitude adjustment, the relative movement of the isolating switch 1 is reduced, and the possibility of sudden swaying caused by attitude adjustment is lowered, thus achieving stable attitude adjustment of the equipment in sloping environments.
[0057] In another preferred embodiment of the present invention, the electrical control box 50 includes an attitude data acquisition module 51, an attitude adjustment control module 52, a walking control module 53, and a display and alarm module 54, such as... Figure 5 As shown; the attitude data acquisition module 51 is used to acquire the attitude signal output by the detection device in real time; the attitude adjustment control module 52 is used to control the synchronous extension and retraction of the two hydraulic cylinders 40 according to the attitude signal; the walking control module 53 is used to control the operation of the tracked walking mechanism 10; the display and alarm module 54 is connected to the attitude data acquisition module 51 by signal, and the display and alarm module 54 is used to display the current transfer attitude information and issue an alarm prompt when the attitude deviation exceeds the preset threshold.
[0058] The electrical control box 50 employs a modular design. The attitude data acquisition module 51 acquires attitude information output by the detection device in real time, providing a continuous data basis for pitch and yaw judgment. The attitude adjustment control module 52 drives two hydraulic cylinders 40 to extend and retract synchronously based on the acquired data, making the pitch compensation action more closely match the slope change and reducing the accumulation of attitude deviations caused by response lag. The walking control module 53 controls the driving state of the tracked walking mechanism 10, enabling the equipment to complete ramp transfer operations at an appropriate speed. In some applications, the walking control module 53 can establish signal interaction with the attitude adjustment control module 52, coordinating the walking speed adjustment and attitude compensation execution to reduce interference from walking actions on compensation adjustment and improve overall operational stability. The display and alarm module 54 displays the current attitude status and issues an alarm when the deviation exceeds a preset threshold, reminding operators to address potential risks promptly. This modular design allows for timely identification and adjustment of attitude deviations, contributing to improved attitude stability and operational safety of the device during ramp operation.
