Description

Technical Field

[0001] This disclosure relates to the field of auxiliary equipment technology for mechanical manufacturing and assembly, and specifically to a tilting and transporting device. Background Technology

[0002] In the manufacturing process of high-voltage circuit breakers, the assembly of the arc-extinguishing chamber is one of the key processes. The arc-extinguishing chamber typically consists of multiple components, including the stationary contact, moving contact, rubber pad, and lifting ring, with the stationary contact alone weighing up to 30 kg. Traditional assembly methods have the following drawbacks: First, multiple people are required to tilt the workpiece, which is time-consuming and prone to collisions, resulting in low efficiency and increased risk of workpiece damage. Second, manually pulling the stationary contact to the tilted position before slowly contacting it with the rubber pad is physically demanding for operators, leading to fatigue over long periods. Third, uneven force application during manual tilting can deform the stationary contact, directly affecting the product's sealing performance and service life. Finally, due to the lack of specialized equipment, the tilting process presents significant safety hazards, with the risk of workpiece slippage and injury.

[0003] While existing technologies include general-purpose hydraulic tilting tables or electric flatbed carts, these devices have limited functionality: hydraulic tilting tables can only perform tilting operations at fixed workstations, failing to meet the transfer needs between different workstations on the assembly line; electric flatbed carts, although capable of transportation, lack precise positioning and tilting functions, making it impossible to adjust the tilt angle required for arc-extinguishing chamber assembly. Furthermore, existing equipment generally suffers from poor adaptability, unable to simultaneously accommodate the tilting and transportation needs of components of different specifications, and even less capable of achieving dynamic balance adjustment during transportation.

[0020] In the following, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings to enable those skilled in the art to readily implement them. Furthermore, for clarity, portions unrelated to the description of exemplary embodiments have been omitted from the drawings.

[0021] In this disclosure, it should be understood that terms such as “comprising” or “having” are intended to indicate the presence of features, figures, steps, behaviors, components, parts or combinations thereof disclosed in this specification, and are not intended to exclude the possibility of the presence or addition of one or more other features, figures, steps, behaviors, components, parts or combinations thereof.

[0022] It should also be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other. This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 3 As shown, the tilting transport device 1 includes: 10 transport vehicles; A flipping mechanism 20 is disposed on one side of the transport vehicle body 10. The flipping mechanism 20 includes a base 21 for fixing the first workpiece A and a drive mechanism 22 connected to the base 21. A grooved fixture 30 that matches the first workpiece A is used to support the first workpiece A after it has been flipped into place; The transport position 40 for transporting the second workpiece B is set on the transport vehicle body 10 and located between the flipping mechanism 20 and the groove tooling 30.

[0024] In this disclosed method, the transport vehicle body 10 adopts an H-beam welded structure, with a detachable counterweight and universal self-locking wheels at the bottom, and is equipped with an electric drive system to achieve stepless speed regulation; the tilting mechanism 20 is connected to the transport vehicle body 10 by a hinge, and includes a base 21 for fixing the first workpiece A and a drive mechanism 22; the groove tooling 30 is set on the transport vehicle body 10 to support the first workpiece A in the tilted position, and the transport position 40 is used to carry the second workpiece B to be transported.

[0025] The H-beam welded structure refers to a frame structure formed by welding H-beams, specifically using a segmented welding process. Its cross-sectional shape has high bending strength and can withstand the torque generated during workpiece flipping. The counterweight refers to a detachable metal block located at the bottom of the vehicle body, specifically a cast iron block with positioning grooves. The vehicle's center of gravity is adjusted by increasing or decreasing the number of counterweights. The omnidirectional self-locking wheel refers to a four-wheel walking mechanism with braking function, specifically polyurethane wheels with foot-locking devices, automatically locking in position when the vehicle is stationary. The electric drive system refers to a power unit powered by a battery pack, specifically using a DC motor and frequency converter, changing the output speed by adjusting the input voltage. The base in the flipping mechanism refers to a support platform with a workpiece fixing structure, specifically a steel plate with fixing holes, fixedly connected to the first workpiece by fasteners such as bolts. The drive mechanism is connected to the base via a hinge, providing driving force for flipping the first workpiece. In the arc-extinguishing chamber assembly scenario disclosed herein, the first workpiece can be a stationary contact, and the second workpiece can be a moving contact.

[0026] Specifically, during operation, the device fixes the first workpiece A to the base and places the second workpiece B on the transport position. The first and second workpieces are transported by a transport vehicle to the work area, where the operator removes the second workpiece. A drive mechanism rotates the first workpiece around the hinge point. When the first workpiece is flipped to the target angle, the grooved fixture automatically supports it and maintains a stable posture. The counterweights at the bottom of the vehicle adjust according to the weight distribution of the currently loaded workpieces to ensure the vehicle does not tilt during the flipping process. The omnidirectional self-locking wheels automatically lock when the vehicle stops to prevent displacement due to uneven ground.

[0027] Compared to existing technologies, traditional hydraulic tilting tables require fixed installation and cannot be moved, while electric flatbed trucks only have transportation functions and lack tilting and positioning capabilities. This solution integrates the tilting mechanism with the transport vehicle body, enabling continuous operation of workpiece transportation and tilting. Operators can complete the assembly process without repeatedly loading and unloading workpieces. The spatial layout design of the grooved tooling and transport position allows the device to process multiple workpieces simultaneously, improving operational efficiency.

[0028] Through the above technical solution, this application effectively solves the problems of requiring multiple people to work together and the limited functionality of equipment in traditional assembly processes. The device achieves coordinated operation of transportation and flipping functions through integrated structural design, and the counterweight adjustment system ensures the stability of the vehicle body during dynamic operations. Operators can complete workpiece transportation, flipping, positioning, and assembly operations single-handedly, significantly reducing labor intensity and safety hazards.

[0029] In one embodiment of this disclosure, the drive mechanism 22 is a hydraulic cylinder or an electric drive rod.

[0030] In this disclosure, a hydraulic cylinder refers to an actuator that outputs linear thrust through a hydraulic system. Specifically, a single-stage double-acting oil cylinder can be used. Its cylinder body is hinged to the transport vehicle body, and the piston rod end is hinged to the base of the tilting mechanism. The extension and retraction of the piston rod is controlled by the change of hydraulic oil pressure, thereby driving the tilting mechanism to complete the adjustment of the workpiece angle.

[0031] An electric drive rod is a mechanical device that achieves linear motion through a motor drive. Specifically, it can be implemented using a combination of a ball screw and a servo motor. After receiving a control signal, the servo motor drives the ball screw to rotate, which in turn moves the sliding nut along the guide rail, thereby pushing the base of the flipping mechanism to rotate around the hinge point, thus achieving the flipping action.

[0032] Specifically, a hydraulic cylinder or an electric drive rod is configured as the core power unit driving the tilting mechanism. When the first workpiece needs to be tilted, the piston rod of the hydraulic cylinder extends or retracts under the control of the hydraulic system, or the lead screw of the electric drive rod rotates under the drive of a servo motor, thereby pushing the base to rotate around the hinge point. The first workpiece fixed on the base tilts synchronously with the base until it reaches the preset support position of the groove tooling. During this process, the stable thrust of the hydraulic cylinder or the precise displacement control of the electric drive rod ensures smooth tilting action and avoids inertial displacement of the workpiece due to sudden speed changes.

[0033] Through the above technical solution, this application solves the problems of low positioning accuracy and high operational danger in traditional manual flipping, enabling heavy workpieces such as arc-extinguishing chambers to be stably flipped during transportation. Operators only need to trigger action commands through the control terminal, avoiding the safety hazards caused by direct contact with the flipping mechanism, and eliminating the risk of workpiece deformation caused by manual operation.

[0034] In one specific embodiment, the drive mechanism 22 is a three-cylinder structure, comprising three independently controlled hydraulic cylinders, each capable of extending and retracting independently to achieve multi-angle flipping of the workpiece. Correspondingly, the flipping and transporting device also includes a hydraulic system comprising a DC pump station providing hydraulic pressure, for example, 15 MPa, to drive the first workpiece flipping, and a mechanical self-locking valve assembly; the mechanical self-locking valve assembly automatically locks the position of the hydraulic cylinders when the hydraulic system stops working or is powered off, preventing accidental movement of the first workpiece.

[0035] A three-cylinder structure refers to a drive assembly consisting of three hydraulic actuators. This can be achieved by using hydraulic cylinders arranged in parallel. Each cylinder is hinged to a different base, and the tilt angle of the base is changed by independently controlling the extension and retraction of each cylinder. Independent control means that each hydraulic cylinder's oil supply circuit has a separate control valve, which can be implemented using an electromagnetic proportional valve. Adjusting the opening of each valve controls the extension and retraction speed and stroke of the corresponding hydraulic cylinder. The hydraulic system is the device that provides power to the hydraulic cylinders. This can be implemented using a gear pump driven by a DC motor. The output flow rate is adjusted by regulating the motor speed, thereby controlling the cylinder's operating speed. The mechanically locking valve assembly is a hydraulic valve assembly with a mechanical holding function. This can be implemented using a spring-loaded pilot-operated check valve. When the hydraulic system loses pressure, the check valve automatically closes to block the hydraulic cylinder's oil circuit.

[0036] In one embodiment of this disclosure, the transport vehicle body 10 is provided with a receiving space 11 for flipping the first workpiece.

[0037] In this disclosure, the accommodating space 11 refers to a recessed area or frame structure provided on the surface of the transport vehicle body. Specifically, it can be implemented using a groove structure formed by welding H-beams, and the depth of the groove can be designed as an adjustable structure according to the workpiece size. This space provides a range of motion for workpiece flipping and prevents collisions during the flipping process.

[0038] In one embodiment of this disclosure, the surface of the receiving space 11 and / or the groove tooling 30 is covered with an elastic buffer pad to prevent the first workpiece from being bumped or damaged when it is flipped into place.

[0039] In this disclosure, the elastic buffer pad refers to a flexible material layer with energy absorption characteristics, which can be made of rubber, polyurethane or silicone, and absorbs the kinetic energy of the workpiece at the moment of contact through material deformation.

[0040] Specifically, after the first workpiece is driven to the target angle by the flipping mechanism, its gravitational potential energy is converted into kinetic energy and it contacts the surface of the groove tooling. At this time, the elastic buffer pad extends the contact time through its own compression deformation, dispersing the impact force to a larger contact area and avoiding direct collision between the metal structures. When the buffer pad is laid synchronously on the side wall of the receiving space, it can prevent the workpiece from lateral rubbing due to inertial swing during the flipping process.

[0041] Through the above technical solution, this application achieves soft landing protection during the workpiece flipping termination stage, eliminating quality defects such as surface scratches and deformation caused by direct collision with the metal structure. In the arc extinguishing chamber assembly scenario, this design can avoid the deformation risk caused by hard contact between the 30kg stationary contact and the tooling, while reducing the frequency of operator intervention in the buffer operation.

[0042] In one embodiment of this disclosure, the groove tooling 30 is connected to the transport vehicle body 10 by a hinge.

[0043] In this disclosure, the groove fixture refers to a support structure that matches the shape of the first workpiece. Specifically, it can be implemented using a U-shaped groove structure with a positioning pin. Its inner contour forms a clearance fit with the workpiece contact surface, which is used to stably support the workpiece after flipping. The hinge method refers to a rotatable connection structure, which can be implemented using a pin shaft and bearing seat. The pin shaft axis forms a spatial perpendicular relationship with the drive axis of the flipping mechanism, allowing the groove fixture to be angled around the hinge point.

[0044] Specifically, the groove fixture can first rotate to one side of the transport vehicle via the hinge point, freeing up the transport position for placing the second workpiece. The transport vehicle simultaneously transports the first and second workpieces. After moving to the work area, the operator removes the second workpiece. The groove fixture is then flipped onto the surface of the transport vehicle, and the drive mechanism rotates the first workpiece around the hinge point. Typically, once the drive mechanism completes the flipping motion of the first workpiece, the groove fixture supports its surface. In some cases, the groove fixture can automatically adjust to a support position parallel to the workpiece's contact surface via the rotational freedom of the hinge point. During this process, the operator does not need to manually adjust the fixture angle; the groove fixture changes its spatial posture synchronously with the flipping motion, and its U-shaped groove maintains a predetermined distance from the workpiece until it is fully supported. This dynamic following characteristic ensures that the workpiece accurately falls into the positioning area of ​​the groove fixture at the final flipping position, avoiding positioning deviations caused by manual intervention.

[0045] Through the above technical solution, this application uses the adaptive angle adjustment function of the hinge structure to ensure that the groove tooling always maintains the best contact state with the workpiece, preventing workpiece slippage or secondary collision damage caused by misalignment of the support surface, and significantly improving the safety and positioning accuracy of the assembly process.

[0046] In one embodiment of this disclosure, the base 21 is provided with a fixing hole 211.

[0047] In this disclosed method, the fixing hole 211 refers to a through hole structure provided on the surface of the base, which can be implemented in the form of a threaded hole or a pin hole, and is used to physically fix the first workpiece by bolts or locating pins. This feature ensures that the workpiece does not shift during the flipping process through mechanical limiting, solving the problem of insufficient stability in traditional manual fixing methods.

[0048] Specifically, during the operation of the flipping mechanism, after the first workpiece is placed on the base surface, the operator can select a fixing hole that matches the preset mounting hole position of the workpiece and insert bolts or locating pins for tightening. For example, in the flipping operation of the stationary contact of the arc-extinguishing chamber, the mounting flange at the bottom of the stationary contact can be connected to the four fixing holes on the base through four sets of M12 bolts to form a rigid fixation. Thus, during the hydraulic cylinder-driven flipping process, the stationary contact and the base maintain a stable connection at all times, avoiding the slippage risk that may occur with traditional manual support.

[0049] Through the above technical solution, this application achieves reliable fixation of the workpiece during the flipping process, eliminates the risk of workpiece collision damage caused by unstable fixation, and reduces the time consumed by operators to adjust the fixing device, making safe operation by a single person possible.

[0050] In one embodiment of this disclosure, a pressure sensor is provided on the base. The pressure sensor is used to monitor the fixing status of the first workpiece in real time and to issue an alarm when the fixing force is less than a preset threshold.

[0051] In this disclosure, the pressure sensor refers to a detection device installed at the contact point between the base and the first workpiece. Specifically, it can be implemented using a piezoelectric sensor or a strain gauge sensor. The stability of the fixed state is determined by detecting the change in contact pressure between the base and the workpiece.

[0052] The preset threshold refers to the minimum safe fixing force value set in advance. The specific value can be determined by experimental measurement or theoretical calculation based on the weight of the workpiece and the fixing requirements. When the actual fixing force is detected to be lower than this value, an alarm signal is triggered.

[0053] Specifically, during the operation of the tilting and conveying device, a pressure sensor is integrated into the contact surface between the base and the first workpiece. When the first workpiece is fixed to the base, the pressure sensor continuously collects pressure data from the contact surface and transmits the signal to the control system. The control system compares the real-time pressure value with a preset threshold. If the pressure value is detected to be consistently below the threshold for a set time, such as 3 seconds, an alarm is triggered via an audible and visual alarm to prompt the operator to check the fixing status. This process automatically starts before the tilting action begins and maintains monitoring throughout the entire tilting process.

[0054] Through the above technical solution, this application effectively solves the problem of unreliability of manual fixing inspection, prevents the workpiece from accidentally moving or falling off during the flipping process due to insufficient fixing force, significantly improves operational safety and quality control accuracy, and reduces the frequency of manual intervention.

[0055] In one embodiment of this disclosure, it further includes: a control system. The control system includes a dual-mode control unit, which independently sets the travel control and the flip control.

[0056] In this disclosure, the dual-mode control unit refers to two control modules with independent computing capabilities. Specifically, it can be implemented using a separate PLC controller or a microcontroller with an integrated dual-core processor. The two modules respectively process the vehicle body movement signal and the tilting mechanism action signal.

[0057] Independent setup refers to the physical isolation of the travel control loop and the rollover control loop at the hardware level. Specifically, this can be achieved by using independent power supply lines, separate operation panels, or process isolation technology at the software level, so that the operation commands of the two control units do not cause signal interference between them.

[0058] Specifically, during the assembly of the arc-extinguishing chamber of a high-voltage circuit breaker, when operators need to perform both transport and tilting actions simultaneously, the dual-mode control unit can activate the travel function of the transport vehicle and the attitude adjustment function of the tilting mechanism separately. For example, during the movement of the stationary contact to the assembly station, the operator can adjust the travel speed of the transport vehicle independently without triggering the tilting mechanism; when it is necessary to tilt and position the 30 kg stationary contact, the extension and retraction angle of the hydraulic cylinder can be controlled independently without affecting the vehicle's position. The two control modules are electrically isolated to prevent accidental operation from causing equipment linkage.

[0059] In some specific implementations, the dual-mode control unit can be configured as two physically separate operating handles, respectively mounted on the pillars on both sides of the transport vehicle body. Furthermore, the control panel can be equipped with a mode switching knob; when the knob is in the travel position, only the omnidirectional wheel drive circuit is activated, and when it is in the tilt position, only the hydraulic system control circuit is activated. As another implementation, an interlock program can be set in the software control interface to automatically cut off the enable signal of the tilt mechanism when a travel command is detected.

[0060] Through the above technical solution, this application effectively solves the problem of misoperation caused by control signal coupling in traditional equipment, enabling a single person to accurately complete the combined action of transporting and flipping heavy workpieces. When performing static contact assembly, the operator can first focus on controlling the transport vehicle to the predetermined workstation, and then operate the flipping mechanism separately to complete the angle fine adjustment. The entire process does not require repeated switching of operating modes, significantly reducing labor intensity and improving assembly positioning accuracy.

[0061] In one embodiment of this disclosure, the transport vehicle body 10 is provided with a foldable tow bar 12.

[0062] In this disclosure, the foldable tow bar 12 refers to a towing structure that connects to the vehicle body via a hinge. Specifically, it can be achieved using a metal rod with a rotating joint and a locking device. A mechanical locking pin is installed at the hinge to secure the tow bar when unfolded. This structure can be connected to external towing equipment in its unfolded state and folds along the edge of the vehicle body during storage to reduce space occupation. Its function is to address the need for a fixed connection when the transport vehicle needs external traction during long-distance movement, while avoiding the space occupation of a fixed tow bar.

[0063] Specifically, a limit stop is installed at the folding joint of the tow bar. When the tow bar is extended to the horizontal position, the limit stop contacts the side wall of the vehicle body to form support. At this time, the tow bar is rigidly fixed by inserting a locking pin into the positioning hole. After the towing operation is completed, the locking pin is pulled out and the tow bar can be rotated downward around the hinge point and folded, and finally attached to the side of the vehicle body by a magnetic fixing device. This structure allows the protruding part of the tow bar to be eliminated when the vehicle body moves in narrow spaces, while quickly forming a rigid connection point when towing is required.

[0064] Through the above technical solution, this application enables the transport vehicle body to have a reliable connection structure during traction operations, while avoiding the impact of fixed traction devices on the working space. Operators can quickly switch the state of the towing rod according to the on-site working conditions, reduce the external dimensions of the equipment when moving in a narrow space, and form a stable force transmission path during traction.

[0065] The above description is merely a preferred embodiment of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this disclosure is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalent features without departing from the inventive concept.
