Description

Technical Field

[0001] This utility model belongs to the field of electrical devices, and specifically relates to an automatic lifting and clamping transfer electrical device. Background Technology

[0002] Electrical equipment is a general term for equipment such as generators, transformers, circuit breakers, and switchgear in a power system. This type of equipment is typically large and heavy, and often requires relocation and handling during its production, installation, inspection, and maintenance.

[0003] Currently, cranes and forklifts are commonly used for lifting or transporting large electrical installations. However, this method has several drawbacks: First, it is unstable during lifting, prone to swaying and tilting, which may damage the precision components inside the electrical installation or scratch the casing. Second, its operation is greatly constrained by environmental factors such as the workspace and ground conditions, making it particularly inconvenient and inflexible in narrow indoor or workshop spaces. Third, the entire operation relies on the operator's experience, posing certain safety risks and resulting in low efficiency.

[0004] To address the aforementioned issues, some dedicated lifting and transfer devices have been disclosed in the prior art. For example, Chinese Patent Publication No. CN211004370U discloses an electrical device lifting and transfer device, which uses a servo motor to drive a bevel gear set, which in turn rotates a lead screw, causing a slider to move along a slide rail and achieve lifting operations in conjunction with a lifting rod. While this solution achieves the dedicated lifting function for electrical devices, its design has significant flaws: the device primarily achieves lifting through the lifting rod, failing to adequately consider the uniform distribution of the weight of the lifted equipment across the device's chassis and support structure. Prolonged exposure to eccentric or concentrated loads can lead to stress concentration in the main structure of the device, making it prone to deformation and significantly reducing its service life and reliability. Furthermore, its anti-deviation stability during transportation needs optimization, affecting the overall efficiency and safety of the transfer operation.

[0005] Therefore, there is an urgent need for a new type of automatic lifting and clamping transfer electrical device to solve the problems of uneven load distribution, insufficient stability and poor adaptability in the existing technology. Utility Model Content

[0006] In order to solve the above-mentioned problems in the prior art, namely uneven load distribution, insufficient stability and poor adaptability, the present invention provides an automatic lifting clamping transfer electrical device, including a support base plate, a lifting mechanism disposed on the support base plate, a support plate driven by the lifting mechanism and used to carry electrical equipment, and a movable locking mechanism disposed at the bottom of the support base plate.

[0007] The lifting mechanism includes a first set of support components distributed at the four corners of the support base plate, and a second set of support components distributed on both sides of the center line of the support base plate;

[0008] The upper ends of both the first set of support components and the second set of support components are connected to the support plate and driven by a power mechanism to synchronously drive the support plate to rise and fall smoothly.

[0009] Furthermore, the first set of support components is an auxiliary support component, including mutually nested and relatively sliding auxiliary support rods and auxiliary hollow support rods;

[0010] The auxiliary support rod is connected to the support base plate, and the auxiliary hollow support rod is connected to the support plate.

[0011] Furthermore, the second set of support components is a transmission support component, including a second support rod with a screw structure, a second hollow support rod nested with the second support rod, and a gear transmission part that drives the second support rod to rotate;

[0012] The second hollow support rod is connected to the support base plate, and the second support rod is connected to the support plate.

[0013] Furthermore, the gear transmission unit includes a driving helical gear and a driven helical gear that mesh with each other;

[0014] The driven helical gear is coaxially threaded to the support rod 2, and the driven helical gear bearing is on the support base plate;

[0015] The power mechanism includes a motor, and the output shaft of the motor is driven to connect to the active helical gear via a rotating shaft.

[0016] Furthermore, the gear transmission unit and the second set of support components are symmetrically arranged in two sets, and the driving helical gears of the two sets of gear transmission units are connected by a linkage rod to achieve synchronous movement.

[0017] Furthermore, the support plate is provided with an automatic clamping mechanism, which includes a second power source, a third transmission mechanism driven by the second power source, and a pair of clamping members driven by the third transmission mechanism and capable of moving in opposite directions.

[0018] Furthermore, the third transmission mechanism includes a lead screw, a sliding seat that is threadedly engaged with the lead screw, and a belt drive assembly that transmits the power from the second power source to the lead screw.

[0019] The pair of clamping members are connected to the sliding seat and can move along the guide rails provided on the support plate.

[0020] Furthermore, the second power source is a second motor;

[0021] The belt drive assembly includes a driving pulley, a driven pulley, and a synchronous belt;

[0022] The output shaft of the second motor is connected to the second rotating shaft and is used to drive the drive wheel;

[0023] The driven wheel is coaxially arranged with the lead screw;

[0024] The timing belt is fitted onto the driving pulley and the driven pulley.

[0025] Furthermore, the guide rail is fixedly mounted on a fixed plate, and the fixed plate is connected to the support plate.

[0026] Furthermore, the movable locking mechanism consists of four omnidirectional casters with braking function, and the four omnidirectional casters are respectively located at the four corners of the bottom of the support base plate.

[0027] The beneficial effects of this utility model are:

[0028] (1) The core of this utility model lies in the unique distributed support structure adopted by the lifting mechanism, namely, the first set of support components distributed at the four corners of the support base plate and the second set of support components distributed on both sides of the center line of the support base plate together form a stable load-bearing frame with multiple support points. This layout is scientific and reasonable, which can evenly distribute the huge weight of the electrical equipment to multiple key stress points of the chassis, greatly improve the stress condition of the device, effectively avoid structural deformation or damage caused by stress concentration, and thus significantly improve the overall load-bearing capacity and long-term reliability and service life of the device.

[0029] (2) In this utility model, since the upper ends of the first and second sets of support components are both connected to the support plate and driven synchronously by a power mechanism, the support plate remains horizontal and under balanced force during the rising or falling process. This synchronous drive mechanism effectively prevents the risk of the support plate tilting, jamming, or equipment shaking during the lifting process, ensuring the stability and safety of the transferred electrical equipment (especially precision and vulnerable equipment), and greatly reducing the possibility of damage to internal components or safety accidents caused by bumps or tilting.

[0030] (3) This utility model forms a stable support system by setting support points at multiple locations (four corners and two sides of the center). This design makes the overall structure of the device more rigid and the center of gravity more stable. It can not only adapt to electrical equipment of different weights and sizes, but also maintain good stability when moving under different ground conditions (such as slight unevenness), thus overcoming the disadvantage of traditional transfer methods being greatly affected by the regional environment.

Detailed Implementation

[0036] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] like Figures 1-3 As shown, this utility model provides an automatic lifting clamping transfer electrical device, including a support base plate 13, a lifting mechanism disposed on the support base plate 13, a support plate 12 driven by the lifting mechanism and used to carry electrical equipment, and a movable locking mechanism disposed at the bottom of the support base plate 13.

[0039] The lifting mechanism includes a first set of support components distributed at the four corners of the support base plate 13, and a second set of support components distributed on both sides of the center line of the support base plate 13.

[0040] The upper ends of the first set of support components and the second set of support components are both connected to the support plate 12 and driven by a power mechanism to synchronously drive the support plate 12 to rise and fall smoothly.

[0041] In this embodiment, the supporting base plate 13 serves as the fundamental load-bearing platform for the entire device. It is preferably made of rectangular steel plate, possessing sufficient thickness and structural strength to withstand the entire weight of the electrical equipment and the device itself. The supporting plate 12 is arranged parallel to the supporting base plate 13, its dimensions matching or slightly smaller than the supporting base plate 13. It is also made of high-strength metal material, and its upper surface can be covered with anti-slip rubber pads to increase friction with the electrical equipment. The movable locking mechanism is fixedly installed at the four bottom corners of the supporting base plate 13, enabling flexible movement and reliable fixation of the device.

[0042] The lifting mechanism includes a first set of support components distributed at the four corners of the support base plate 13, and a second set of support components distributed on both sides of the centerline of the support base plate 13. The first and second sets of support components together form a stable and load-bearing three-dimensional support frame. Specifically, the four first sets of support components are precisely installed at the four corner areas of the support base plate 13 in a rotatable or fixed manner at their bottom ends, thereby providing anti-torsional and anti-tilting stability. The two second sets of support components are symmetrically distributed on the left and right sides of the longitudinal centerline of the support base plate 13, and their bottom ends are also connected to the support base plate 13. They serve as the main power actuation components, responsible for providing the main force required for lifting.

[0043] The upper ends of both the first and second sets of support components are connected to the support plate 12 and driven by a power mechanism to synchronously and smoothly raise and lower the support plate 12. The connection between the first set of support components and the support plate 12 can be hinged or fixed, and its main function is to guide the support plate 12 to maintain a horizontal posture and share the load. The connection between the second set of support components and the support plate 12 is a power connection, and it contains a transmission mechanism that can convert rotational motion into linear motion. The power mechanism is fixedly installed on the support base plate 13 or a fixed structure connected to it, and its output end is connected to the power input end of the second set of support components through a coupling, drive shaft, or gear system, thereby synchronously transmitting power to the second set of support components on both sides. After the power mechanism is started, it drives the second set of support components on both sides to extend and retract at the same speed and stroke, thereby driving the support plate 12 connected to it and the support plate 12 guided by the first set of support components to achieve smooth vertical raising and lowering without jamming or tilting. The power mechanism can be various types of rotary motors combined with necessary reducers. Its control method can be manual switch control or automatic control with integrated controller to ensure the synchronization and smoothness of the lifting process.

[0044] See Figure 1 As a further explanation of this utility model, the first set of support components is an auxiliary support component, including an auxiliary support rod 7 and an auxiliary hollow support rod 8 that are nested together and can slide relative to each other;

[0045] The auxiliary support rod 7 is connected to the support base plate 13, and the auxiliary hollow support rod 8 is connected to the support plate 12.

[0046] In this embodiment, the auxiliary support rod 7 is a solid or thick-walled hollow metal rod with a precision-machined outer diameter, forming a high-precision dynamic fit with the inner diameter of the auxiliary hollow support rod 8. Lubricant can be applied between them to reduce sliding friction resistance. The auxiliary hollow support rod 8 is a section of round tube closed at one end, with the closed end serving as the connecting end. The lower end of the auxiliary support rod 7 is vertically fixed to the upper surface of the support base plate 13 by welding or flange bolt connection, and its installation position must precisely correspond to the four corners of the support base plate 13, i.e., the four vertices of the rectangular base plate. After installation, the axis of the auxiliary support rod 7 should be perpendicular to the upper surface of the support base plate 13. The closed end of the auxiliary hollow support rod 8 is vertically fixed to the lower surface of the support plate 12 by welding or flange bolt connection, with its installation position corresponding vertically to the auxiliary support rod 7 on the support base plate 13. After installation, the upper section of the auxiliary support rod 7 is nested into the cavity of the auxiliary hollow support rod 8, forming a retractable sleeve structure. When the support plate 12 moves up and down during the lifting process, the auxiliary hollow support rod 8 slides relative to the auxiliary support rod 7. The four sets of such auxiliary support components work together to greatly enhance the structural rigidity and stability of the support plate 12 during the lifting process, effectively preventing it from shifting or tilting in the horizontal direction, and ensuring that the lifting action is smooth and reliable.

[0047] The connection between the bottom end of the auxiliary support rod 7 and the support base plate 13 is preferably a non-removable welded connection to ensure connection strength and prevent wobbling. Similarly, the connection between the closed end of the auxiliary hollow support rod 8 and the support plate 12 is achieved by welding or by bolts to a threaded hole pre-embedded in the lower surface of the support plate 12. To limit the sliding stroke and prevent complete separation, a limiting block or limiting pin can be provided at the upper end of the auxiliary support rod 7, and a corresponding limiting boss can be provided inside the lower end or the inner side of the open end of the cavity of the auxiliary hollow support rod 8.

[0048] See Figure 1 and Figure 3 As a further explanation of this utility model, the second set of support components is a transmission support component, including a second support rod 9 with a screw structure, a second hollow support rod 10 nested with the second support rod 9, and a gear transmission part that drives the second support rod 9 to rotate;

[0049] The hollow support rod 10 is connected to the support base plate 13, and the support rod 9 is connected to the support plate 12.

[0050] The gear transmission unit includes a driving helical gear 3 and a driven helical gear 4 that mesh with each other;

[0051] The driven helical gear 4 is coaxially threadedly connected to the support rod 9, and the driven helical gear 4 is bearing on the support base plate 13;

[0052] The power mechanism includes a motor 1, and the output shaft of the motor 1 is driven to connect to the active helical gear 3 via a rotating shaft 5.

[0053] The second support rod 9 and the support plate 12 can be fixed by welding or flange.

[0054] In this embodiment, the second set of support components is a transmission support component, which constitutes the core power actuator for realizing the lifting function. This transmission support component mainly includes a second support rod 9 with a screw structure, a second hollow support rod 10 sleeved on the outside of the second support rod 9, and a gear transmission part that drives the second support rod 9 to move axially. The second support rod 9 is a precision-machined trapezoidal screw or ball screw, with a complete external thread machined on the lower half of its body, which is used to mate with the gear transmission part; the upper half of the rod body is a smooth shaft section, the top of which is machined with a threaded hole or flange structure for connection with the support plate 12.

[0055] The gear transmission unit is used to drive the support rod 9 to produce axial movement. Specifically, the gear transmission unit includes a pair of meshing driving helical gears 3 and driven helical gears 4. The driven helical gear 4 has an internally threaded hole machined at its center, matching the external thread at the lower end of the support rod 9, forming a coaxial threaded transmission connection between the two. The driven helical gear 4 is supported on the support base plate 13 by a pair of angular contact ball bearings or thrust bearings. Specifically, a bearing housing is machined or installed on the support base plate 13 at a position corresponding to the driven helical gear 4. This bearing housing is used to fix and support the outer ring of the bearing, while the inner ring of the bearing is interference-fitted with the journal of the driven helical gear 4 or a specially designed support portion. This bearing mounting method allows the driven helical gear 4 to rotate freely around its own axis, but its axial and radial positions are completely constrained by the bearings; that is, it can only rotate and cannot move up and down or left and right.

[0056] The hollow support rod 2 10 is positioned below the driven helical gear 4. It is a cylindrical steel sleeve with openings at both ends, its inner diameter slightly larger than the outer diameter of the smooth shaft section of the support rod 2 9, forming a clearance fit. Its main function is to act as a protective cover, protecting the internal threaded joint from external dust and foreign objects, while also providing auxiliary radial support for the support rod 2 9, enhancing its stability under pressure and preventing the slender lead rod from becoming unstable and bending. The lower end of the hollow support rod 2 10 is directly and vertically fixed to the upper surface of the support base plate 13 by welding or bolts, with its axis aligned with the axis of the driven helical gear 4.

[0057] The second support rod 9 extends downwards, with its lower threaded section screwed into the internal threaded hole at the center of the driven helical gear 4 supported by the bearing, and protruding a certain length from below. This protruding portion is located within the internal cavity of the hollow support rod 10. The upper end of the second support rod 9 extends upwards and is rigidly fixed to the lower surface of the support plate 12 using high-strength bolts through a threaded hole or flange at its top. Therefore, there is no relative movement between the second support rod 9 and the support plate 12.

[0058] The power mechanism includes a motor 1. The motor 1 is preferably a servo motor or stepper motor with a gearbox, which is bolted to an independent motor support base 2. The motor support base 2 is bolted to a placement plate 11 located above a support base plate 13. The output shaft of the motor 1 is connected to one end of a rotating shaft 5 via a coupling or directly. The rotating shaft 5 is supported by two support bases to ensure smooth rotation. The other end of the rotating shaft 5 is connected and fixed to the driving helical gear 3 via a key, thereby transmitting the output torque of the motor 1 to the driving helical gear 3.

[0059] When motor 1 starts, it drives shaft 5 and the active helical gear 3 to rotate. The active helical gear 3 drives the driven helical gear 4, which meshes with it, to rotate. Since the driven helical gear 4 is fixed by bearings and can only rotate but not move axially, according to the screw drive principle, its rotational motion will force the threaded support rod 9 to move axially upward or downward. The support rod 9 drives the support plate 12, which is fixedly connected to it, to complete a precise lifting and lowering motion. The two symmetrically arranged transmission support assemblies are connected to the active helical gear 3 or shaft 5 on both sides by a linkage rod 27 to ensure absolutely synchronous movement, thereby ensuring that the support plate 12 lifts and lowers smoothly without the risk of uneven load or jamming. The hollow support rod 10 remains stationary throughout the lifting and lowering process.

[0060] The positioning plate 6 is a rigid plate structure, preferably made of steel plate. It is vertically fixed to the left end of the upper surface of the placement plate 11 by bolts or welding. A through hole is precisely machined in the center of the positioning plate 6, and a deep groove ball bearing or sliding bearing is installed in the hole. The middle part of the rotating shaft 5 or the end away from the motor 1 passes through the inner hole of the bearing, so that the other end of the rotating shaft 5 is reliably supported by the bearing on the positioning plate 6. This design ensures the concentricity and stability of the rotating shaft 5 during high-speed rotation, prevents it from deflecting or vibrating due to its own weight or gear meshing force, and improves transmission accuracy and service life.

[0061] See Figure 1 As a further explanation of this utility model, the gear transmission part and the second set of support components are symmetrically arranged in two sets, and the driving helical gears 3 of the two sets of gear transmission parts are connected by a linkage rod 27 to achieve synchronous movement.

[0062] In this embodiment, two sets of gear transmission units and the second set of support components are symmetrically arranged, located at both ends of the support base plate 13 along its length. To ensure that the lifting and lowering movements on both sides are completely synchronized and to avoid tilting, jamming, or additional stress on the support plate 12 due to the displacement difference between the two sides during the lifting and lowering process, the active helical gears 3 of the two sets of gear transmission units are connected to each other through a rigid linkage rod 27 to achieve absolute mechanical synchronization.

[0063] Specifically, the linkage 27 is a precision-machined straight shaft with sufficient torsional stiffness, preferably made of high-quality carbon structural steel. Both ends of the linkage 27 are securely and coaxially fixed to the hubs of the driving helical gears 3 on the left and right sides via keyways and keys, or via flanges and set screws. The linkage 27 is installed on the side of the driving helical gear 3 opposite to the meshing side, i.e., away from the driven helical gear 4, to avoid motion interference with other components. To ensure smooth torque transmission, the linkage 27 requires auxiliary support from at least one intermediate support. This intermediate support is bolted to the support base plate 13 or a fixed structure rigidly connected to the support base plate 13. A rolling bearing is installed inside the support, and the linkage 27 passes through the inner hole of the bearing, providing rotational support and preventing it from sagging due to its own weight, thus ensuring smooth transmission.

[0064] When motor 1 starts and drives one of the active helical gears 3 to rotate via shaft 5, torque is immediately and synchronously transmitted to the other active helical gear 3 through the rigidly connected linkage 27. This ensures that the active helical gears 3 on both sides always maintain the same speed and direction of rotation. The active helical gears 3 on both sides then drive the two driven helical gears 4 meshing with them to rotate synchronously, thus ensuring that the internal threads of the two sets of screw and nut pairs, i.e., the driven helical gears 4, operate in perfect harmony with the external threads of the support rod 9. Ultimately, this causes the two support rods 9 to rise or fall at the same speed, driving the support plate 12 to achieve a smooth and vertical movement without any deviation. This purely mechanical rigid synchronization scheme is far more reliable than the scheme using two motors to control electronic synchronization separately, completely eliminating the risk of asynchrony caused by electronic control errors or single motor failures.

[0065] See Figure 2 and Figure 3 As a further explanation of the present invention, the support plate 12 is provided with an automatic clamping mechanism, which includes a second power source, a third transmission mechanism driven by the second power source, and a pair of clamping members 14 driven by the third transmission mechanism and capable of moving in opposite directions.

[0066] The third transmission mechanism includes a lead screw 24, a sliding seat 16 threadedly engaged with the lead screw 24, and a belt drive assembly that transmits the power from the second power source to the lead screw 24.

[0067] The pair of clamping members 14 are connected to the sliding seat 16 and can move along the guide rail 15 provided on the support plate 12.

[0068] The second power source is a second motor 18;

[0069] The belt drive assembly includes a driving pulley 22, a driven pulley 23, and a synchronous belt 21;

[0070] The output shaft of the second motor 18 is connected to the second rotating shaft 20 and is used to drive the drive wheel 22;

[0071] The driven wheel 23 is coaxially arranged with the lead screw 24;

[0072] The synchronous belt 21 is engaged and sleeved on the driving pulley 22 and the driven pulley 23.

[0073] In this embodiment, an automatic clamping mechanism is provided on the support plate 12 to automatically clamp and fix the electrical equipment after it is lifted to the transport position, preventing slippage or overturning during movement. The automatic clamping mechanism mainly includes a second power source providing power, a third transmission mechanism converting rotational motion into linear motion, and a pair of clamping members 14 that ultimately perform the clamping action. The second power source is fixedly installed below or to the side of the support plate 12. The input end of the third transmission mechanism is connected to the output end of the second power source, and its output end is connected to the clamping members 14. The pair of clamping members 14 are preferably made of high-strength steel plates, and their inner contact surfaces can be adhered with anti-slip and anti-static rubber pads to increase friction and protect the equipment surface.

[0074] The third transmission mechanism specifically includes a lead screw 24, two sliding seats 16 threadedly engaged with the lead screw 24, and a belt drive assembly that transmits power from the second power source to the lead screw 24. The lead screw 24 is a bidirectional lead screw, with its middle section serving as a mounting reference section. Opposite-direction external threads are machined on its left and right sides, one end being a left-hand thread and the other a right-hand thread. The sliding seats 16 are block-shaped structures with internal threaded holes at their centers matching the corresponding thread direction on the lead screw 24. The two sliding seats 16 are screwed onto the left and right-hand threaded sections of the lead screw 24, respectively. The belt drive assembly connects the output shaft of the second power source and the input end of the lead screw 24 to achieve speed reduction and power transmission.

[0075] The lower parts of the pair of clamping members 14 are fixedly connected to the top of one of the sliding seats 16 by bolts or welding. Two precision linear guides 15 are fixedly installed on the upper surface of the support plate 12, parallel to the axis of the lead screw 24. The sliders of the linear guides 15 are fixedly connected to the bottom or side of the sliding seats 16. Therefore, the pair of clamping members 14 are supported by the sliding seats 16 below them and can slide along the linear guides 15. The function of the guides 15 is to withstand the lateral and torsional torques generated during clamping, ensuring that the clamping members 14 can only move smoothly along a preset straight trajectory without shaking or jamming.

[0076] The second power source is specifically a second motor 18. The second motor 18 is preferably a small geared motor, which is fixed by a second motor support 19. The second motor support 19 is fastened to a fixed plate 17 located below the support plate 12 by bolts.

[0077] The belt drive assembly specifically includes a driving pulley 22, a driven pulley 23, and a closed synchronous belt 21. The driving pulley 22 is a small-diameter synchronous pulley, which is fixedly mounted on the rotating shaft 20 by a key connection.

[0078] The output shaft of the second motor 18 is connected to one end of a second rotating shaft 20 via a coupling or directly, for driving the drive wheel 22 to rotate. The second rotating shaft 20 is supported on the fixed plate 17 by two bearing seats.

[0079] The driven pulley 23 is a large-diameter synchronous belt pulley, which is coaxially fixed to one end of the lead screw 24, typically the optical shaft end, via a key connection. The diameter of the driven pulley 23 is significantly larger than that of the driving pulley 22, forming a transmission ratio that reduces speed and increases torque.

[0080] The synchronous belt 21 is tightly engaged with the teeth of the driving pulley 22 and the driven pulley 23, and the tension is adjusted appropriately by the tensioner to prevent slippage.

[0081] When motor 18 is powered on, it drives shaft 20 and drive wheel 22 to rotate. Power is transmitted to driven wheel 23 via synchronous belt 21, thereby driving the bidirectional lead screw 24 to rotate. Since the two sliding seats 16 are respectively engaged with left and right threaded connections, and their rotational movement is restricted by guide rail 15, when the lead screw 24 rotates, the two sliding seats 16 carry the clamping element 14 in opposite or opposing linear movements along guide rail 15, thus achieving automatic clamping and releasing. By controlling the direction and number of rotations of motor 18, the clamping stroke and clamping force can be precisely controlled.

[0082] See Figure 3 As a further explanation of this utility model, the guide rail 15 is fixedly installed on a fixing plate 17, and the fixing plate 17 is connected to the support plate 12.

[0083] The guide rail 15 is indirectly and securely mounted on the support plate 12 via a fixing plate 17. The fixing plate 17, serving as the basic mounting platform for the entire automatic clamping mechanism, is a rectangular steel plate with sufficient flatness and rigidity.

[0084] One main surface of the fixing plate 17 is detachably and rigidly vertically connected to the side surface of the support plate 12 via a plurality of high-strength hexagon socket head cap screws. Specifically, a series of threaded blind holes with a specified spacing are pre-machined on the side surface of the support plate 12. Matching open holes are machined on the corresponding lateral connecting surface of the fixing plate 17. During installation, the lateral connecting surface of the fixing plate 17 is aligned and fitted with the side surface of the support plate 12, so that the open holes are aligned with the threaded holes on the side surface of the support plate 12. Then, the hexagon socket head cap screws are passed through the open holes from one side of the fixing plate 17 and screwed into the threaded holes on the side surface of the support plate 12, and tightened to the specified torque using a torque wrench. To ensure the verticality and rigidity of the connection, at least two locating pins can be set between the lateral contact surfaces of the fixing plate 17 and the support plate 12 for positioning. One or more L-shaped angle irons can be added between the bottom of the fixing plate 17 and the upper surface of the support plate 12 as auxiliary support and reinforcing ribs. One side of the angle iron is connected to the fixing plate 17 by bolts, and the other side is connected to the upper surface of the support plate 12, thereby forming a stable triangular support structure that effectively resists the overturning moment generated during clamping.

[0085] The two guide rails 15 are fixedly mounted parallel to each other on the other main surface of the fixing plate 17, namely the outer surface opposite to the connecting surface, by bolts. To ensure the absolute parallelism of the two guide rails 15 and their parallelism with the upper surface of the support plate 12, the installation reference line of the guide rails 15 is first marked on the outer surface of the fixing plate 17 using a precision measuring instrument. Multiple elongated mounting holes are machined on the base of each guide rail 15 to facilitate straightness adjustment. During installation, the guide rails 15 are placed on the reference line, and the bolts are initially tightened. Then, using a high-precision optical level or a 90-degree angle ruler, with the upper surface of the support plate 12 as a reference, the parallelism of the two guide rails 15 and their parallelism with the upper surface of the support plate 12 are finely adjusted. After adjustment, all mounting bolts are finally tightened according to the specified tightening sequence and torque value, firmly locking the guide rails 15 onto the fixing plate 17.

[0086] This design, which mounts the fixing plate 17 laterally onto the support plate 12, saves valuable space on the upper surface of the support plate 12, resulting in a flatter and more open placement area for the equipment. The entire clamping mechanism is integrated into a single, side-mounted module via the fixing plate 17, facilitating offline assembly, debugging, and maintenance. The robust lateral connection structure ensures sufficient rigidity and stability to withstand the forces and torques generated during clamping operations.

[0087] See Figure 1 and Figure 2 As a further explanation of this utility model, the movable locking mechanism consists of four universal casters 25 with braking function, and the four universal casters 25 are respectively located at the four corners of the bottom of the support base plate 13.

[0088] Four swivel casters 25 are respectively located at the four corners of the bottom of the support base plate 13. Each swivel caster 25 consists of a caster bracket, a roller, a steering bearing, and a braking mechanism. The caster bracket is securely fixed to the four corner areas of the lower surface of the support base plate 13 using four high-strength hex bolts of grade 8.8 or higher, along with anti-loosening washers, via a mounting plate on its top. The installation position of each corner has been precisely calculated and positioned to ensure that the support points of the four swivel casters 25 form a stable rectangular support surface, thereby ensuring extremely high stability of the device when stationary and in motion, and preventing tipping.

[0089] The rollers of the swivel casters 25 are preferably made of polyurethane or nylon, which have high load-bearing capacity, wear resistance, and a certain degree of shock absorption. Each caster is designed with an independent braking mechanism, which typically includes a pedal-type wheel brake to limit the rotation of the roller and a steering lock to lock the caster's steering function. When the wheel brake pedal is pressed down, a friction block presses against the roller to prevent it from rolling; when the steering lock is pressed down or rotated, a locking pin engages with the positioning hole in the caster bracket to prevent the caster from rotating around its vertical axis.

[0090] When the device needs to be moved, the operator ensures that the brakes on all swivel casters 25 are released. At this point, the device can be moved flexibly in any direction by pushing the handle 26. The 360-degree steering function of the swivel casters 25 gives the device excellent maneuverability, allowing for easy steering and movement even in confined spaces. Once the device is moved to the target working position, the operator must sequentially depress or rotate the brakes on all four swivel casters 25, simultaneously locking the rollers' rolling and steering functions. This four-point locking mechanism ensures a rigid connection between the device and the ground during operation, completely eliminating the risk of accidental movement and providing an extremely stable and reliable foundation for subsequent lifting and clamping operations.

[0091] See Figure 1 and Figure 2 The device also includes a handrail 26, which is disposed on the side of the supporting base plate 13.

[0092] The handrail 26 is located on the side of the supporting base plate 13. As the main force-applying component of the manual operation device, the handrail 26 is made of a section of bent steel pipe or high-strength metal pipe. Its shape is usually an inverted "U" shape or an arched structure with a horizontal push rod. Its height is designed according to ergonomics so that the operator can comfortably hold and push and pull it while standing.

[0093] The lower end of the handrail 26 is rigidly connected to the side of the support base plate 13 via two sturdy mounting brackets. Specifically, at two predetermined positions on the left and right sides of one side of the support base plate 13, usually near but not limited to the two ends of that side, a vertically upward connecting plate or mounting lug is welded or fixed with high-strength bolts. Each connecting plate is machined with at least two mounting holes.

[0094] The left and right legs at the lower end of the handrail 26 are respectively connected to one of the connecting plates. A flange with mounting holes can be welded to the end of each leg, or the leg itself can have through holes machined directly corresponding to the mounting holes on the connecting plate. High-strength bolts, nuts, and anti-loosening washers are used to securely fasten the flanges or through holes at the ends of the left and right legs of the handrail 26 to the connecting plates welded to the sides of the support base plate 13. To ensure connection strength and resist torques in all directions generated during pushing, pulling, and turning, a triangular reinforcing rib can be added at the connection point. One side of this reinforcing rib is welded to the connecting plate, and the other side is welded to the upper or side surface of the support base plate 13.

[0095] The surface of the handrail 26 may be covered with a layer of non-slip, soft, elastic material, such as rubber or foam plastic, to increase grip comfort and safety. To facilitate the operator's movement and easy start / stop of the control device, the control switches for motor 1 and motor 2 18, as well as the emergency stop button, may be installed on or near the horizontal bar of the handrail 26 at an easily accessible location. All control cables may be routed through cable trays laid inside or outside the conduit wall of the handrail 26 to the electrical control box.

[0096] The handrail 26 provides the operator with an ergonomic point of force application. By pushing or pulling the handrail 26, the force can be effectively transmitted to the support base plate 13 and the device can be flexibly moved, turned and positioned through the casters 25, which greatly facilitates the handling of the equipment and reduces the labor intensity of the operators.

However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
