Electromechanical device hoisting device

Abstract

The application provides a hoisting device for electromechanical equipment. When hoisting, the electromechanical equipment is clamped and positioned by the hoisting device above the electromechanical equipment through a grabbing assembly. Then, a jetting assembly is started before hoisting or when pre-lifting starts, and jetting is performed towards the contact between the bottom of the electromechanical equipment and the ground to destroy the sealing and adhesion of the contact interface, form a pressure relief and air inlet channel and reduce static friction. Under the action of jetting, the pre-lifting assembly implements small-stroke and controllable pre-lifting, so that the bottom surface of the equipment is separated from the ground as much as possible simultaneously and gently in the circumferential direction, and attitude disturbance caused by single-angle separation from the platform is avoided. Through the cooperative action of the pre-lifting assembly arranged on the outer periphery of the grabbing area and the jetting assembly located at the lower end of the pre-lifting assembly, directional jetting is performed at the contact, vacuum adsorption or adhesion is rapidly destroyed, and static friction is reduced, so that the peak value of the pulling force at the moment of hoisting and the overturning moment caused thereby are significantly reduced.

Description

Technical Field

[0001] This invention relates to the field of hoisting technology for electromechanical equipment, and more particularly to a hoisting device for electromechanical equipment. Background Technology

[0002] Because electromechanical equipment is very heavy, hoisting equipment is needed to lift it during installation or transportation in order to move it to other locations.

[0003] During the hoisting process, because the electromechanical equipment is very heavy and integrates a variety of important components, if its horizontal and vertical alignment cannot be guaranteed during hoisting, the internal components of the electromechanical equipment will be damaged, which will lead to the electromechanical equipment failing to operate normally.

[0004] Especially before the hoisting begins, the bottom of some electromechanical equipment is tightly attached to the ground. At this time, the bottom of the electromechanical equipment adheres to or is adsorbed by the ground (including vacuum adsorption). Due to factors such as bottom adhesion / adsorption (including vacuum adsorption), static friction engagement, and uneven mass distribution inside the equipment, transient additional loads and overturning moments will be generated.

[0005] At the moment of lifting, the suction force must be overcome (e.g., a vacuum can reach about 0.1 MPa × effective sealing area). At the moment of lifting, the hook tension increases suddenly. This transient additional load will cause the lifting tension to increase suddenly, and the equipment is prone to one corner leaving the platform first, resulting in pitch / tilt, which will damage the horizontality and verticality.

[0006] Current methods often employ padding and prying to mitigate the effects of adhesion, but these methods suffer from drawbacks such as reliance on experience for efficiency, limitations imposed by workspace and safety risks, and difficulty in proactively and in real-time suppressing adhesion and maintaining equipment posture throughout the lifting process. Therefore, improvements are needed to reduce the additional load / overturning tendency caused by adhesion and static friction during lifting without adding complex procedures, and to effectively control the equipment's posture during the lifting process. Summary of the Invention

[0007] Therefore, it is necessary to propose a hoisting device for electromechanical equipment to address the aforementioned problems.

[0008] A hoisting device for electromechanical equipment, the hoisting device comprising:

[0009] Connecting bracket, with connecting plate;

[0010] The gripping component is located on the connecting plate and has a clamping space;

[0011] A pre-lifting component is disposed on the connecting plate and surrounds the gripping component to lift the electromechanical equipment within the clamping space;

[0012] The jet assembly is located at the end of the pre-lift assembly away from the connecting plate;

[0013] Specifically, before hoisting or when the pre-lifting assembly lifts the electromechanical equipment in the clamping space, the jetting assembly is used to jet air at the contact point between the electromechanical equipment in the clamping space and the ground.

[0014] In at least one embodiment of this application, the jet assembly includes:

[0015] A support column is mounted on the pre-lifting assembly at one end and is connected to the pre-lifting assembly in a transmission manner. An air jet hole is provided at the end of the support column away from the pre-lifting assembly, and the air jet hole is positioned towards the clamping space.

[0016] An air pump is mounted on the support column and is connected to the air jet port.

[0017] In at least one embodiment of this application, the axis of the jet hole is denoted as the first connecting line, and the angle between the first connecting line and the end face of the support column away from the pre-lifting component is α, satisfying the relationship: 30 degrees ≤ α ≤ 60 degrees.

[0018] In at least one embodiment of this application, the grasping component includes:

[0019] The gripping jaws are multiple, forming a clamping space between them, and each jet assembly is aligned with one of the gripping jaws.

[0020] In at least one embodiment of this application, the corresponding jet assembly and the corresponding gripper form a linkage assembly. In the linkage assembly, the gripping direction of the gripper is set along a first direction, and the jet hole of the jet assembly is set along a second direction. The angle between the first direction and the second direction is denoted as b, which satisfies the relationship: b = 45 degrees.

[0021] In at least one embodiment of this application, the grasping component further includes:

[0022] A gyroscope is mounted on the gripping jaws;

[0023] During the hoisting process, the gyroscope is used to obtain the horizontal and vertical angles of the gripping claws, so as to adjust the air output of the air jets corresponding to the jet assembly, thereby controlling the horizontal and vertical angles of the electromechanical equipment.

[0024] In at least one embodiment of this application, a guide groove is provided at one end of the support column near the connecting plate;

[0025] The pre-lift component includes:

[0026] A connecting column is fixed at one end to the connecting plate. The end of the connecting column away from the connecting plate has a movable groove, and a guide rod extends from the end of the connecting column away from the connecting plate. The guide rod is slidably connected to the guide groove.

[0027] The telescopic hydraulic cylinder has one end housed in the movable groove and fixedly connected to the connecting column, and the other end fixedly connected to the support column.

[0028] In at least one embodiment of this application, the junction of the jet hole and the peripheral surface of the support column is recessed inward to form an arc-shaped surface.

[0029] In at least one embodiment of this application, the connecting bracket further includes:

[0030] The hook is located on the side of the connecting plate away from the gripping component, and the hook has a connecting hole for connecting with an external hook.

[0031] In at least one embodiment of this application, the grasping component includes:

[0032] The suspension component is rotatably connected to the connecting plate at one end and has multiple suspension holes at the other end. Each of the gripping claws is provided with a suspension ring, and each suspension ring passes through the corresponding suspension hole.

[0033] Divided by the normal direction of the connecting plate, the two gripping jaws on the same side are rotatably connected.

[0034] In the two sets of gripping claws on both sides, there is a fixing rod between the two sets of gripping claws.

[0035] The electromechanical equipment hoisting device of this embodiment will have at least the following beneficial effects:

[0036] The aforementioned electromechanical equipment hoisting device, during hoisting, positions itself above the electromechanical equipment and clamps and positions it using the gripping components. Then, before lifting or when pre-lifting begins, the jet assembly is activated, spraying air towards the contact point between the bottom of the electromechanical equipment and the ground to disrupt the seal and adhesion at the contact interface, forming a depressurization and air intake channel and reducing static friction. Under the action of the jet, the pre-lifting component performs a small-stroke, controllable pre-lift, allowing the bottom surface of the equipment to leave the ground as simultaneously and gently as possible along the circumference, avoiding attitude disturbances caused by a single angle leaving the platform first. Based on load and attitude feedback, the jet and pre-lift can be performed alternately or in parallel to achieve a coordinated process of depressurization before lifting or depressurization while lifting. After the bottom surface is completely detached and the attitude is stable, the main lifting stage of the external lifting equipment begins, and the jet can be maintained for a short period of time as needed to prevent secondary adhesion.

[0037] By cooperating with the pre-lifting components arranged around the periphery of the gripping area and the jetting components located at its lower end, jetting is directed at the contact point to quickly break the vacuum adsorption or adhesion and reduce static friction, significantly reducing the peak tension at the moment of lifting and the resulting overturning moment.

[0056] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] This invention provides a hoisting device 100 for electromechanical equipment, the hoisting device 100 comprising:

[0058] The connecting bracket 110 has a connecting plate 111.

[0059] The gripping component 120 is disposed on the connecting plate 111 and has a clamping space 121.

[0060] The pre-lifting component 130 is disposed on the connecting plate 111 and surrounds the gripping component 120 to lift the electromechanical equipment in the clamping space 121.

[0061] The jet assembly 140 is located at the end of the pre-lift assembly 130 away from the connecting plate 111.

[0062] Specifically, before hoisting or when the pre-lifting assembly 130 lifts the electromechanical equipment in the clamping space 121, the jetting assembly 140 is used to jet air at the contact point between the electromechanical equipment in the clamping space 121 and the ground.

[0063] Please refer to Figures 1-6In this embodiment, during hoisting, the device is positioned above the electromechanical equipment and clamped and positioned by the gripping component 120. Then, before hoisting or when pre-lifting begins, the jet component 140 is activated to spray air towards the contact point between the bottom of the electromechanical equipment and the ground to disrupt the seal and adhesion of the contact interface, forming a depressurization and air intake channel and reducing static friction. Under the action of the jet, the pre-lifting component 130 performs a small-stroke, controllable pre-lift, so that the bottom surface of the equipment leaves the ground as simultaneously and gently as possible along the circumference, avoiding attitude disturbance caused by the single-angle departure from the platform first. According to the load and attitude feedback, the jet and pre-lift can be carried out alternately or in parallel to achieve a coordinated process of depressurization before lifting or depressurization while lifting. After the bottom surface is completely detached and the attitude is stable, the main hoisting stage of the external lifting equipment begins. The jet can be maintained for a short period of time as needed to prevent secondary adhesion.

[0064] By cooperating with the pre-lifting component 130 arranged around the periphery of the gripping area and the jetting component 140 located at its lower end, jetting is directed at the contact point, which quickly breaks the vacuum adsorption or adhesion and reduces static friction, significantly reducing the peak tension at the moment of lifting and the resulting overturning moment.

[0065] The surrounding small-stroke pre-lift allows the bottom surface to separate nearly simultaneously along the circumference, suppressing pitch and tilt caused by one corner leaving the platform first, thereby maintaining the levelness and verticality of the equipment.

[0066] The sequential or parallel execution of jet propulsion and pre-lifting ensures a smooth load transfer process, reducing the risk of impact and off-center loading on internal components.

[0067] The jet assembly 140 is located at the end of the pre-lift assembly 130 away from the connecting plate 111, which shortens the airflow path and improves airflow utilization and accuracy.

[0068] In at least one embodiment of this application, the jet assembly 140 includes:

[0069] The support column 141 is mounted on the pre-lifting component 130 at one end and is connected to the pre-lifting component 130 in a transmission manner. The end of the support column 141 away from the pre-lifting component 130 is provided with an air jet hole 142, which is oriented toward the clamping space 121.

[0070] An air pump 143 is mounted on the support column 141 and is connected to the air jet port 142.

[0071] Please refer to Figures 1-6In this embodiment, the support column 141 is fixed (e.g., screwed / flange connected) to the end of the pre-lifting assembly 130 and connected to it in a transmission manner, so that the support column 141 moves synchronously with the lifting / lowering of the pre-lifting assembly 130; the support column 141 is provided with a gas flow channel inside, and at least one jet hole 142 is machined at the end away from the pre-lifting assembly 130. The jet direction of the jet hole 142 is towards the clamping space 121, preferably towards the contact point between the equipment and the ground at the bottom periphery of the electromechanical equipment.

[0072] An air pump 143 is installed in the middle or upper part of the support column 141. The outlet of the air pump 143 is directly connected to the jet hole 142 through the internal flow channel of the support column 141 (one or more of the following can be installed at the pump outlet or the front end of the jet hole for starting, stopping and fine-tuning the flow rate). The air inlet of the air pump 143 can be connected to an external air source or ambient air through a flexible tube.

[0073] During hoisting, after the gripping component 120 completes the clamping and positioning of the equipment, the air pump 143 is started to drive the air jet. The airflow is directed to the contact point through the short channel inside the support column 141, which breaks the negative pressure seal and adhesion or adsorption between the bottom surface and the ground, and reduces static friction.

[0074] Subsequently or simultaneously, the pre-lifting component 130 performs a small-stroke pre-lift. Since the support column 141 is connected to the pre-lifting component 130 and the jet hole 142 is fixed at the end of the support column 141, the jet direction and jet distance remain basically constant during the pre-lifting process, so that the airflow continues to act on the most needed interface position, thereby achieving rapid unsticking and uniform separation in the coordinated process of depressurization and lifting.

[0075] The jet nozzle 142 is close to the contact point and sprays towards the clamping space 121, which can quickly destroy the vacuum adsorption and adhesion film, significantly reducing the peak tension at the moment of lifting and the resulting overturning moment.

[0076] The air pump 143 is mounted on the support column 141, which significantly reduces pressure drop and delay, makes the jet output more stable, and facilitates coordination with the pre-lift short stroke.

[0077] The support column 141 is connected to the pre-lifting component 130 via a transmission. The jet nozzle 142 maintains a stable relative posture and distance with the contact point throughout the pre-lifting process, preventing the fixed nozzle from deviating due to the lifting of the equipment and ensuring that the airflow is effective and continuous.

[0078] After the jet weakens the adsorption and static friction, combined with the small stroke pre-lift, the bottom surface leaves the platform more evenly along the circumference, suppressing the pitch or tilt caused by one corner of the electromechanical equipment leaving the platform first, and protecting the internal components of the equipment.

[0079] It should be noted that the connecting plate 111 is roughly in the shape of an "I", the support column 141 is a straight column, and the jet hole 142 is a through hole.

[0080] In at least one embodiment of this application, the axis of the jet hole 142 is denoted as the first connecting line 180, and the angle between the first connecting line 180 and the end face of the support column 141 away from the pre-lift assembly 130 is α, satisfying the relationship: 30 degrees ≤ α ≤ 60 degrees.

[0081] Please refer to Figures 1-6 In this embodiment, the axis of the jet hole 142 is defined as the first connecting line 180, and the angle between the connecting line and the end face (the end of the support column 141 away from the pre-lifting assembly 130 forms the end face) is α, and α is set within 30° to 60°, and the jet direction is directed towards the contact point between the bottom of the electromechanical equipment and the ground in the clamping space 121.

[0082] During hoisting, after clamping and positioning, the jet is activated first, so that the airflow along the direction of angle a has both a peeling component along the ground tangentially and a pressure relief component pointing towards the contact edge, which preferentially tears the seal at the bottom edge of the equipment, introduces outside air, and establishes a pressure relief channel.

[0083] Subsequently, or simultaneously, a small-stroke pre-lift is implemented, and the support column 141 moves synchronously with the pre-lift action. The relative relationship between the injection direction and the contact point remains basically unchanged, thus continuously and accurately acting on the key interface during the coordinated process of jet unloading and pre-lift separation.

[0084] The reason for controlling 'a' within the range of 30° to 60° is that too small an angle will cause the airflow to slide away too close to the surface and have insufficient ability to enter the gap; too large an angle will tend to be vertical impact, increasing vortices and back jets and reducing effective pressure relief.

[0085] The 30° to 60° range comprehensively takes into account the three effects of ingress pressure relief, boundary layer suction and tangential stripping, which facilitates rapid and gentle interface separation and attitude stability within a limited spray distance.

[0086] The jet creates a combined effect of pressure relief, peeling and sweeping at the contact edge, which can quickly destroy vacuum adsorption and adhesion and reduce static friction, significantly reducing the peak tensile force at the moment of lifting and the resulting overturning moment.

[0087] The nozzle moves synchronously with the pre-lift and is always aligned with the action area. The air jet and the small stroke pre-lift work together to make the load transfer curve smoother, suppress the pitch and tilt caused by one corner of the electromechanical equipment leaving the platform first, and improve the levelness and verticality of the equipment.

[0088] In at least one embodiment of this application, the grasping component 120 includes:

[0089] There are multiple gripping claws 122, and the gripping space 121 is formed between the multiple gripping claws 122. Each jet assembly 140 is aligned with one gripping claw 122.

[0090] Please refer to Figures 1-6 In this embodiment, the gripping component 120 adopts a multi-claw structure, with multiple gripping claws 122 distributed circumferentially and surrounding to form a clamping space 121 for reliably clamping and positioning the electromechanical equipment; correspondingly, the jetting component 140 is arranged at multiple points and corresponds one-to-one with the gripping claws 122, that is, each jetting component 140 is installed at the same circumferential position as its corresponding gripping claw 122 and faces the clamping space 121, so that the jetting direction is aligned with the contact zone between the electromechanical equipment and the ground near the gripping claw 122.

[0091] During hoisting, the gripping jaws 122 first hold and position the outline or reinforcing edge. Then, before hoisting or during the synchronous pre-lifting stage, all or part of the jet assembly 140 is activated, so that each nozzle forms a directional airflow at the edge of the contact zone between the electromechanical equipment and the ground near its respective gripping jaws 122, which preferentially tears the seal of the contact interface, introduces outside air, and reduces static friction.

[0092] At the same time, the pre-lifting component 130 performs a small-stroke lift. Since the jet point and the clamping point correspond in the circumferential position, the airflow plays a synergistic role in depressurization, stripping and sweeping at the corners where the force is applied, so that the bottom surface tends to detach from the ground simultaneously and gently in the circumferential direction, avoiding pitching or tilting caused by a certain point detaching first.

[0093] It should be noted that, in order to adapt to different equipment shapes and contact conditions, the number and distribution of gripping claws 122 (such as three-point, four-point or multi-point symmetrical) as well as the installation position, nozzle angle, flow rate and opening sequence of each jet assembly 140 can be set as needed; by setting adjustable mounting slots or adjustable nozzles at corresponding positions, it is ensured that the jet direction is always aligned with the edge of the contact zone between the electromechanical equipment and the ground near the gripping claw 122, so that it continuously acts on the contact surface between the electromechanical equipment and the ground throughout the entire process of jet unloading and small stroke pre-lift.

[0094] By arranging the jet assembly 140 and the gripper 122 in a one-to-one correspondence, pressure relief and friction reduction can be completed simultaneously at each critical circumferential position of force and positioning, making the bottom surface separation more uniform and significantly suppressing the instability caused by one corner of the electromechanical equipment leaving the platform first.

[0095] The jet always stays close to the edge of the contact zone between the electromechanical equipment and the ground near the gripper 122, reducing ineffective jetting and flow waste, lowering pressure drop and response lag, and improving gas energy utilization and control accuracy.

[0096] Multi-point parallel directional jetting, combined with multi-jaw clamping and short-stroke pre-lifting, can effectively reduce the peak tensile force and overturning moment during lifting, thereby reducing the risk of impact and off-center loading on internal components.

[0097] In at least one embodiment of this application, the corresponding jet assembly 140 and the corresponding gripper 122 form a linkage assembly 170. In the linkage assembly 170, the gripping direction of the gripper 122 is set along a first direction C, and the jet hole 142 of the jet assembly 140 is set along a second direction D. The angle between the first direction C and the second direction D is denoted as b, which satisfies the relationship: b = 45 degrees.

[0098] Please refer to Figures 1-6 In this embodiment, each jet assembly 140 and its corresponding gripper 122 are kept in a constant relative posture by a connecting bracket 110, and the two constitute a linkage assembly 170.

[0099] The gripping direction of the gripper 122 is defined as the first direction C (usually the radial direction pointing to the center of gravity of the clamped device or the normal of the connecting plate 111 when the gripper 122 is closed), and the jetting direction of the jet nozzle 142 of the jet assembly 140 is defined as the second direction D, and the included angle b between the first direction C and the second direction D is fixed at 45°.

[0100] During hoisting, the gripping jaws 122 close in the first direction C to reliably hold the outer surface or reinforcing edge of the equipment. Then, before hoisting or during pre-lifting, the jet nozzles 142 blow in the second direction D, causing the jet stream to form a combined airflow on the ground and equipment contact zone adjacent to the contact edge of the gripping jaws 122. This airflow contains both a tangential peeling component (the tangential component along the gripping direction of the gripping jaws 122) and a normal pressure relief component (the normal component pointing towards the contact gap). This weakens static friction and engagement along the main force direction of the gripping jaws 122.

[0101] On the other hand, air is supplied into the contact gap to disrupt the local vacuum adsorption and establish a pressure relief channel. Since the geometric relationship between the air jet hole 142 and the gripping claw 122 is b=45°, under the multi-claw arrangement, each linkage component 170 works synchronously and collaboratively in the circumferential direction, realizing the integrated process of air jet unloading and small stroke pre-lifting, and suppressing the first departure from the stage on one side or one corner.

[0102] The 45° synthetic jet simultaneously achieves tangential peeling along the gripping direction and normal pressure relief towards the contact gap, which can more quickly destroy adhesion and adsorption and reduce static friction under a unit air volume, thereby reducing the peak tensile force at the moment of lifting and the resulting overturning moment.

[0103] The air jet acts on the leading edge of the main force-bearing edge of the gripper 122, and in conjunction with the symmetrical distribution of the circumferential multi-claw, the bottom surface tends to detach more simultaneously along the circumferential direction, significantly reducing the pitch and tilt caused by the electromechanical equipment leaving the platform at one corner first.

[0104] It should be noted that the gripper 122 has a rectangular frame structure, and one corner extends outward to form an extended arm.

[0105] In at least one embodiment of this application, the grasping component 120 further includes:

[0106] A gyroscope 160 is mounted on the gripper 122.

[0107] During the hoisting process, the gyroscope 160 is used to obtain the horizontal and vertical angles of the gripping claw 122, so as to adjust the air output of the air jet hole 142 corresponding to the air jet assembly 140, thereby controlling the horizontal and vertical angles of the electromechanical equipment.

[0108] Please refer to Figures 1-6 In this embodiment, a gyroscope 160 is provided on the gripper 122 to acquire the horizontal and vertical angles of the gripper 122 (which represents the clamped device) and their changing trends in real time throughout the hoisting process.

[0109] The attitude information is compared with the target attitude (such as zero deflection angle in horizontal and vertical directions) to generate error signals of deflection angle and angular velocity. The control unit then performs closed-loop adjustment of the air output of the corresponding jet assembly 140 jet hole 142.

[0110] When a deviation angle or a trend of increasing deviation angle is detected in a certain direction, the air volume of the jet hole 142 on the opposite side of that direction is increased and the air volume on the same side is decreased, forming a controllable differential aerodynamic torque, which causes the equipment to generate a corrective tendency opposite to the deviation angle, thereby continuously correcting the attitude before it is lifted into place.

[0111] When a sudden crosswind causes the angular velocity to exceed the threshold, the corresponding jet volume on the opposite side is briefly increased to form an anti-wind pulse, and after the deflection angle falls back into the dead zone, it smoothly converges to a steady-state jet. The linkage components 170 in different areas can operate independently or in coordination to avoid excessive correction and oscillation caused by sudden changes in wind load or lifting speed.

[0112] By using the real-time measurement of the gyroscope 160 to drive the differential jet, it is possible to perform rapid and directional aerodynamic compensation for external disturbances such as wind loads, so that the horizontal and vertical angles of the equipment are maintained within a small deflection range, significantly reducing the swaying, torsion and secondary impact caused by crosswinds.

[0113] Based on the independent or coordinated movement of the linkage components 170 in different areas, the equipment deflection angle is directly changed by airflow changes and the wind effect is suppressed in real time, which improves the posture stability, safety and operation efficiency of hoisting.

[0114] In at least one embodiment of this application, a guide groove 1411 is provided at one end of the support column 141 near the connecting plate 111.

[0115] The pre-lift component 130 includes:

[0116] A connecting post 131 is fixed at one end to the connecting plate 111. The end of the connecting post 131 away from the connecting plate 111 has a movable groove 1311, and a guide rod 1312 extends from the end of the connecting post 131 away from the connecting plate 111. The guide rod 1312 is slidably connected to the guide groove 1411.

[0117] The telescopic hydraulic cylinder 132 has one end housed in the movable groove 1311 and fixedly connected to the connecting column 131, and the other end fixedly connected to the support column 141.

[0118] Please refer to Figures 1-6 In this embodiment, during hoisting, the hydraulic cylinder extends or retracts to drive the support column 141 to perform a small stroke pre-lift relative to the connecting plate 111. The guide rod 1312 slides in the guide groove 1411, providing linear constraint and anti-rotation constraint for the movement of the support column 141. The axial thrust generated by the hydraulic cylinder is reliably transmitted to the support column 141 and the jet assembly 140 in a predetermined direction, so that the jet nozzle is always aligned with the contact zone between the electromechanical equipment and the ground in the clamping space 121 throughout the pre-lifting process.

[0119] Significantly reduces the swaying and rotation of the support column 141 relative to the connecting plate 111, ensuring continuous alignment of the jet at the critical edge position, and suppressing the first departure of one corner of the electromechanical equipment from the platform and the resulting pitch and tilt.

[0120] On the other hand, it converts external disturbances (such as crosswinds and uneven resistance caused by local adhesion) into lateral reaction forces that can be borne by the guide pair, reducing the lateral load on the hydraulic cylinder piston rod, reducing wear and jamming risks, and improving the life and reliability of the structure.

[0121] Linear guidance ensures that the pre-lift force line is more consistent with the line connecting the equipment's center of gravity, making the coordination of jetting and pre-lifting smoother and more controllable. This allows for more stable unloading without adding complex procedures, reducing the peak instantaneous tensile force and overturning moment during lifting, and improving the maintenance of lifting posture, safety, and operational efficiency.

[0122] It should be noted that the guide groove 1411 is a "T"-shaped groove, the movable groove 1311 is a rectangular groove, and the guide rod 1312 is a protruding structure that is roughly "T"-shaped.

[0123] In at least one embodiment of this application, the junction of the jet hole 142 and the peripheral surface of the support column 141 is recessed inward to form an arc-shaped surface 1421.

[0124] Please refer to Figures 1-6In this embodiment, the jet hole 142 is opened through the wall of the support column 141, and the junction between the jet hole 142 and the outer peripheral surface of the support column 141 is not made with a straight edge, but is recessed inward and processed into a smooth arc transition surface (e.g., in the form of a flared mouth / rounded chamfer).

[0125] During jetting, the airflow is ejected from the inner cavity of the support column 141 through the nozzle. Guided by the arc transition, it forms a stable jet stream with lighter wall separation, smaller contraction, and weaker shear. Even if the jet direction is at an angle relative to the end face as mentioned above, the arc transition can avoid turbulent vortex detachment and back suction caused by sharp edges, making it easier for the jet stream to enter the narrow gap near the contact zone between the equipment and the ground to release pressure and peel off along the edge.

[0126] In at least one embodiment of this application, the connecting bracket 110 further includes:

[0127] The hook 150 is located on the side of the connecting plate 111 away from the gripping component 120, and the hook 150 has a connecting hole 1501 for connecting with an external hook.

[0128] Please refer to Figures 1-6 In this embodiment, the hook 150 is fixed to the connecting plate 111 by integral molding or full welding, and a connecting hole 1501 is provided on it for reliable connection with an external hook. The hook 150 is arranged vertically relative to the plane of the connecting plate 111, and the edge of the connecting hole 1501 is rounded or chamfered to allow the hook to be quickly positioned and the force to be even.

[0129] It should be noted that the lug 150 is roughly a triangular plate structure, and the connecting hole 1501 is a through hole.

[0130] In at least one embodiment of this application, the grasping component 120 includes:

[0131] The suspension component 123 is rotatably connected to the connecting plate 111 at one end and has multiple suspension holes 1231 at the other end. Each of the gripping claws 122 is provided with a suspension ring 124, and each suspension ring 124 passes through the corresponding suspension hole 1231.

[0132] Divided by the normal of the connecting plate 111, the two gripping jaws 122 on the same side are rotatably connected.

[0133] In the two sets of gripping claws 122 on both sides, a fixing rod 125 is provided between the two sets of gripping claws 122.

[0134] Please refer to Figures 1-6In this embodiment, the suspension holes 1231 can be arranged along a straight line or an arc so as to select appropriate hole positions according to different equipment shapes, so that each gripping claw 122 can obtain a reasonable geometric position and foot spacing in the circumferential and radial directions.

[0135] Divided by the normal of the connecting plate 111, the two gripping claws 122 on each side are connected to each other by a revolute joint, forming a linkage pair on the same side, so that when gripping, they can open and close slightly around the axis of rotation to form a stable triangular or quadrilateral support geometry.

[0136] A fixing rod 125 is provided between the two sets of gripping claws 122 on both sides to maintain the distance and relative posture on both sides during the gripping process and resist lateral opening and twisting.

[0137] Before hoisting, the suspension component 123 is swung out from under the connecting plate 111 and the appropriate hole position is selected to position each suspension ring 124. Then the operator drives the gripping claw 122 to close and hold the edge or reinforcement of the equipment.

[0138] The same-side rotating connection allows the two claws to adapt and fit together even with local shape and position errors or changes in wrap angle. The fixing rod 125 connects the two sides into a whole, limiting the relative sway and torsion between the left and right sides. The rotational freedom between the suspension component 123 and the connecting plate 111 allows the gripping claws 122 group to automatically follow the direction of force and gravity during lifting and pre-lifting, thus keeping in line with the rhythm of air jet unloading and surrounding pre-lifting, reducing local stress and attitude disturbances caused by geometric mismatch and load transients.

[0139] It should be noted that the suspension component 123 is roughly a ring-shaped clamp structure.

[0140] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0141] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
