Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hoisting of electromechanical equipment, and particularly relates to a hoisting device for electromechanical equipment. BACKGROUND

[0002] Due to the fact that the electromechanical equipment is very heavy, a hoisting device needs to be used to hoist the electromechanical equipment in the process of installing or carrying the electromechanical equipment, so as to transport the electromechanical equipment to other positions.

[0003] However, in the hoisting process, due to the fact that the electromechanical equipment is very heavy and is internally integrated with various important components, if the levelness and verticality cannot be guaranteed in the hoisting process, the components inside the electromechanical equipment will be damaged, and thus the electromechanical equipment cannot normally operate.

[0004] Especially before the hoisting starts, the bottom of some electromechanical equipment is tightly attached to the ground, at this time, the bottom of the electromechanical equipment is attached to the ground to form adhesion, adsorption and the like (including vacuum adsorption), and due to the factors such as adhesion / adsorption (including vacuum adsorption) of the bottom, static friction engagement and uneven distribution of the internal mass of the equipment, transient additional load and overturning moment are generated.

[0005] The suction force (for example, the vacuum can reach about 0.1 MPa x effective sealing area) needs to be overcome at the moment of lifting, the hook tension suddenly increases at the moment of lifting, the transient additional load causes the lifting tension to suddenly increase, and the equipment is prone to be separated from the platform at one corner, and pitch / roll is generated, so as to damage the levelness and verticality.

[0006] The existing operation mostly uses cushion blocks and prying to relieve the problem, but there are disadvantages such as that the efficiency depends on experience, the operation space and safety risk are limited, and it is difficult to actively and real-timely inhibit the adhesion and adsorption influence and cooperatively maintain the equipment posture in the whole lifting process. Therefore, how to reduce the additional load / overturning tendency caused by adhesion and adsorption and static friction at the moment of lifting without increasing complex procedures, and how to effectively control the posture in the hoisting process, still need to be improved.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0023] The present application provides an electromechanical equipment hoisting device 100, which comprises: The connecting support 110 has a connecting plate 111.

[0024] The grabbing assembly 120 is arranged on the connecting plate 111 and has a clamping space 121.

[0025] The pre-lifting assembly 130 is arranged on the connecting plate 111 and surrounds the grabbing assembly 120 to lift the electromechanical equipment in the clamping space 121.

[0026] The air jet assembly 140 is arranged at an end of the pre-lifting assembly 130 away from the connecting plate 111.

[0027] The air jet assembly 140 is used to jet air at the contact between the electromechanical equipment in the clamping space 121 and the ground before hoisting or when the pre-lifting assembly 130 lifts the electromechanical equipment in the clamping space 121.

[0028] Please refer to Figures 1-6 In this embodiment, the device clamps and positions the electromechanical equipment above the electromechanical equipment by the grabbing assembly 120 before hoisting, and then starts the air jet assembly 140 to jet air towards the contact between the bottom of the electromechanical equipment and the ground to break the seal and adhesion of the contact interface, form a pressure relief and air inlet channel, and reduce the static friction before hoisting or starting pre-lifting. Under the action of the air jet, the pre-lifting assembly 130 implements small-stroke and controllable pre-lifting, so that the bottom surface of the equipment can be separated from the ground as much as possible at the same time and gently in the circumferential direction, avoiding attitude disturbance caused by single-angle first separation from the platform. According to the load and attitude feedback, the air jet and the pre-lifting can be alternately or simultaneously performed to realize the cooperative process of first pressure relief and then lifting or simultaneous pressure relief and lifting. After the bottom surface is completely separated and the attitude is stable, the main hoisting stage of the external hoisting equipment is entered, and the air jet can be kept for a short time as needed to prevent secondary adhesion.

[0029] Through the cooperative action of the pre-lifting assembly 130 arranged on the outer periphery of the grabbing area and the air jet assembly 140 located at the lower end thereof, directional air jet is performed at the contact, vacuum adsorption or adhesion is quickly broken, and the static friction is reduced, thereby significantly reducing the peak value of the pulling force at the moment of hoisting and the overturning moment caused thereby.

[0030] The circumferential small-stroke pre-lifting makes the bottom surface separate at the same time in the circumferential direction, thereby suppressing the pitch and roll caused by single-angle first separation from the platform, and thus maintaining the levelness and perpendicularity of the equipment.

[0031] The sequential or simultaneous cooperation of the air jet and the pre-lifting makes the load transfer process smooth, and reduces the risk of impact and eccentric load on the internal components.

[0032] The air jet assembly 140 is arranged at the end of the pre-lifting assembly 130 away from the connecting plate 111, thereby shortening the airflow action path, improving the airflow utilization rate and action accuracy.

[0033] In at least one embodiment of the present application, the air jet assembly 140 comprises: A support column 141 is mounted at one end on the pre-lifting assembly 130 and in transmission connection with the pre-lifting assembly 130. A jet hole 142 is formed at the end of the support column 141 away from the pre-lifting assembly 130, and the jet hole 142 is arranged towards the clamping space 121.

[0034] A gas pump 143 is mounted on the support column 141 and in communication with the jet hole 142.

[0035] Please refer to Figures 1-6 In this embodiment, the support column 141 is fixed (such as screwed / flange connected) to the end of the pre-lifting assembly 130 and in transmission connection with the pre-lifting assembly 130, so that the support column 141 moves synchronously with the lifting / falling of the pre-lifting assembly 130. The support column 141 is internally provided with a gas flow channel, and at least one jet hole 142 is formed at the end of the support column 141 away from the pre-lifting assembly 130. The jet direction of the jet hole 142 is towards the clamping space 121, and preferably points to the device-ground contact at the bottom periphery of the electromechanical device.

[0036] The gas pump 143 is mounted on the middle or upper part of the support column 141, and the outlet of the gas pump 143 is directly communicated with the jet hole 142 through the internal flow channel of the support column 141 (one or more of the check valve, throttle valve, and electromagnetic valve can be arranged at the front end of the pump outlet or the jet hole for starting and stopping and flow adjustment). The gas inlet end of the gas pump 143 can be communicated with the external gas source or the ambient air through a flexible pipe.

[0037] During hoisting, after the clamping and positioning of the device by the grabbing assembly 120 is completed, the gas pump 143 is started to drive the jet, and the gas flow is directed to the contact through the internal short channel of the support column 141, to destroy the negative pressure seal and adhesion or adsorption between the bottom surface and the ground, and to reduce the static friction.

[0038] Subsequently or simultaneously, the pre-lifting assembly 130 implements a small-stroke pre-lifting. Since the support column 141 is in transmission connection with the pre-lifting assembly 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, so that the gas flow continuously acts on the interface position that needs it most, thereby achieving rapid unstick and uniform separation in the cooperative process of pressure relief and lifting.

[0039] The jet hole 142 is close to the contact and jets towards the clamping space 121, which can quickly destroy the vacuum adsorption and adhesion film, and significantly reduce the peak value of the lifting force at the moment of hoisting and the overturning moment caused thereby.

[0040] The gas pump 143 is mounted on the support column 141, and the pressure drop and delay are significantly reduced, and the jet output is more stable, which is convenient for cooperation with the small-stroke pre-lifting.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] The nozzles are synchronized with the pre-lifting, always aligned with the action area, and the jet and the small-stroke pre-lifting are matched with each other, so that the load transfer curve is smoother, and the pitching and rolling caused by the corner of the electromechanical equipment first leaving the platform is inhibited, and the levelness and perpendicularity of the equipment are improved.

[0052] In at least one embodiment of the present application, the grabbing assembly 120 comprises: A plurality of grabbing clamps 122, the grabbing clamps 122 form the clamping space 121 between them, and each jet assembly 140 is aligned with one grabbing clamp 122.

[0053] Please refer to Figures 1-6 In this embodiment, the grabbing assembly 120 adopts a multi-claw structure, a plurality of grabbing clamps 122 are distributed in the circumferential direction and surround the clamping space 121, which is used to reliably clamp and position the electromechanical equipment; correspondingly, the jet assembly 140 is arranged in multiple points, and corresponds to the grabbing clamps 122 one by one, that is, each jet assembly 140 is installed at the same circumferential position as the corresponding grabbing clamp 122, and faces the clamping space 121, so that the jet direction is aligned with the contact band of the electromechanical equipment and the ground near the grabbing clamp 122.

[0054] During hoisting, the grabbing clamps 122 first complete the holding and positioning of the outline or reinforcing edge, and then all or part of the jet assemblies 140 are started before lifting or during the synchronous pre-lifting stage, so that each nozzle forms a directional airflow at the edge of the contact band of the electromechanical equipment and the ground near the respective grabbing clamp 122, preferentially tearing the seal of the contact interface, introducing external air, and reducing static friction.

[0055] At the same time, the pre-lifting assembly 130 implements small-stroke lifting, and since the jet points and the clamping points correspond in the circumferential position, the airflow plays a synergistic role in pressure relief, peeling and cleaning at the stressed corner, so that the bottom surface tends to simultaneously and gently separate from the ground in the circumferential direction, avoiding the pitching or rolling caused by the separation of a certain place first.

[0056] It should be noted that in order to adapt to different equipment shapes and contact conditions, the number and distribution of the grabbing clamps 122 (such as three-point, four-point or multi-point symmetry) and the installation pose, jet angle, flow and opening timing of each jet assembly 140 can be set as needed; by setting adjustable installation slots or adjustable nozzles at the corresponding positions, the jet direction is always aligned with the edge of the contact band of the electromechanical equipment and the ground near the corresponding grabbing clamp 122, so that the contact surface of the electromechanical equipment and the ground is continuously acted on during the whole process of jetting and small-stroke pre-lifting.

[0057] The one-to-one arrangement of the air jet assembly 140 and the grabbing jaw 122 can simultaneously complete pressure relief and friction reduction at each key circumferential position under force and positioning, making the bottom surface separation more uniform and significantly inhibiting the instability of the posture caused by the mechanical and electrical equipment corner first leaving the platform.

[0058] The air jet is always attached to the edge of the contact band between the mechanical and electrical equipment and the ground near the grabbing jaw 122, reducing invalid blowing and flow waste, reducing pressure drop and response lag, and improving gas energy utilization and control accuracy.

[0059] The multi-point parallel directional air jet combined with multi-jaw clamping and small stroke pre-lifting can effectively reduce the tension peak and overturning moment at the instant of lifting, reducing the impact and unbalanced load risk of internal components.

[0060] In at least one embodiment of the present application, the corresponding air jet assembly 140 and the corresponding grabbing jaw 122 form a linkage assembly 170, in which the grabbing direction of the grabbing jaw 122 is arranged along a first direction C, and the air jet hole 142 of the air jet assembly 140 is arranged along a second direction D, the included angle between the first direction C and the second direction D is denoted as b, and the relationship is: b = 45 degrees.

[0061] Please refer to Figures 1-6 In this embodiment, each air jet assembly 140 and its corresponding grabbing jaw 122 maintain a constant relative attitude through the connecting bracket 110, and the two constitute a linkage assembly 170.

[0062] The grabbing direction of the grabbing jaw 122 is defined as the first direction C (usually the radial direction of the grabbing jaw 122 pointing to the center of gravity of the clamped device or the normal line of the connecting plate 111 when the grabbing jaw 122 is closed), and the jet direction of the air jet hole 142 of the air 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°.

[0063] During lifting, the grabbing jaw 122 is closed in the first direction C to reliably hold the outer surface or the reinforced edge of the device; then before lifting or during pre-lifting, the air jet hole 142 blows in the second direction D, so that the jet flow forms a combined air flow containing both a tangential peeling component (a tangential component along the grabbing direction of the grabbing jaw 122) and a normal pressure relief component (a normal component pointing to the contact gap) on the ground adjacent to the contact edge of the grabbing jaw 122 and the device contact band, thereby weakening the static friction and engagement along the main force direction of the grabbing jaw 122.

[0064] In another aspect, air is sent into the contact gap to destroy the local vacuum adsorption and establish a pressure relief channel. Due to the geometric relationship b = 45° between the air jet hole 142 and the gripping jaw 122, in the multi-jaw arrangement, each linkage assembly 170 works synchronously and cooperatively in a zoned manner around the circumference to realize the integration of air jet unloading and small stroke pre-lifting, and to inhibit unilateral or single-angle first-off.

[0065] The 45° synthetic jet stream simultaneously considers tangential peeling along the gripping direction and normal pressure relief directed to the contact gap, and under a unit air volume, it can destroy the adhesion and adsorption faster and reduce the static friction, thereby reducing the lifting moment of force peak value and the overturning moment caused thereby.

[0066] The air jet acts on the leading edge of the force main side of the gripping jaw 122, and cooperates with the symmetrical distribution of the circumferential multi-jaw to make the bottom surface more tend to be simultaneously separated along the circumference, thereby significantly reducing the pitch and roll caused by the single-angle first-off of the electromechanical equipment.

[0067] It should be noted that the gripping jaw 122 is a rectangular frame structure, and one side is inclined to extend an installed extension arm.

[0068] In at least one embodiment of the present application, the gripping assembly 120 further comprises: A gyroscope 160 is installed on the gripping jaw 122.

[0069] During lifting, the gyroscope 160 is used to obtain the horizontal angle and vertical angle of the gripping jaw 122, to adjust the air output of the air jet hole 142 corresponding to the air jet assembly 140, and to control the horizontal angle and vertical angle of the electromechanical equipment.

[0070] Please refer to Figures 1-6 In this embodiment, a gyroscope 160 is arranged on the gripping jaw 122 to obtain the horizontal angle and vertical angle of the gripping jaw 122 (and further the clamped equipment) and their change trends in real time during the whole lifting process.

[0071] The attitude information is compared with the target attitude (such as the horizontal and vertical degrees being zero deflection angles), error signals of the deflection angles and angular velocities are generated, and the air output of the air jet hole 142 corresponding to the air jet assembly 140 is closed-loop adjusted by a control unit.

[0072] When a deflection angle or a deflection angle growth trend in a certain direction is detected, the air output of the air jet hole 142 on the opposite side of the direction is increased and the air output on the same side is decreased to form a controllable differential aerodynamic moment, so as to make the equipment have a correction tendency opposite to the deflection angle, thereby continuously correcting the attitude from lifting to positioning.

[0073] When the sudden side wind causes the angular velocity to exceed the threshold, the short-time increase of the corresponding opposite side jet forms an anti-wind pulse, and after the deflection angle falls within the dead zone, it is smoothly converged to the steady-state jet; the linkage assembly 170 in different regions can operate independently or cooperatively to avoid excessive correction and oscillation caused by sudden wind load or lifting speed change.

[0074] The real-time measurement of the gyroscope 160 drives the differential jet, which can quickly and correctly compensate for external disturbances such as wind load, so that the horizontal angle and vertical angle of the device are maintained within a small deflection angle range, significantly reducing the deflection, torsion and secondary impact caused by side wind.

[0075] According to the independent or cooperative movement of the linkage assembly 170 in different regions, the airflow changes directly change the deflection angle of the device and immediately suppress the wind influence, which improves the attitude stability, safety and operation efficiency of the lifting.

[0076] In at least one embodiment of the present application, the support column 141 is provided with a guide groove 1411 near one end of the connecting plate 111.

[0077] The pre-lifting assembly 130 comprises: The connecting column 131 is fixed at one end to the connecting plate 111, and the connecting column 131 is provided with a movable groove 1311 at the end away from the connecting plate 111, and the connecting column 131 extends a guide rod 1312 away from the connecting plate 111, and the guide rod 1312 is slidably connected with the guide groove 1411.

[0078] The telescopic hydraulic cylinder 132 is received in the movable groove 1311 and fixedly connected with the connecting column 131 at one end, and fixedly connected with the support column 141 at the other end.

[0079] Please refer to Figures 1-6 In this embodiment, during lifting, the hydraulic cylinder extends or retracts to drive the support column 141 to make a small stroke pre-lifting 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, reliably transmitting the axial thrust generated by the hydraulic cylinder to the support column 141 and the jet assembly 140 in the predetermined direction, so that the jet port is always aligned with the contact band between the electromechanical equipment and the ground in the clamping space 121 during the entire pre-lifting process.

[0080] Significantly reduce the swing and rotation of the support column 141 relative to the connecting plate 111, ensure the continuous alignment of the jet at the key edge position, and suppress the angle of the electromechanical equipment from the platform and the resulting pitch and roll.

[0081] Another aspect converts external disturbances (such as uneven resistance caused by side wind and local adhesion) into lateral reaction forces that can be borne by the guide vice, reduces the lateral load on the hydraulic cylinder piston rod, reduces the risk of wear and jamming, and improves the service life and reliability of the structure.

[0082] The linear guide ensures that the pre-lifting force line is more consistent with the device gravity center line, makes the cooperation of the jet and the pre-lifting more smooth and controllable, and thus realizes more stable unloading, reduces the instantaneous tension peak and the overturning moment of the lifting, improves the lifting posture retention, safety and operation efficiency without increasing complex procedures.

[0083] It should be noted that the guide groove 1411 is a "T"-shaped groove, the movable groove 1311 is a rectangular recess, and the guide rod 1312 is a "T"-shaped protruding structure.

[0084] In at least one embodiment of the present application, the intersection between the jet hole 142 and the peripheral surface of the support column 141 is inwardly recessed to form an arc surface 1421.

[0085] Please refer to Figures 1-6 In the present embodiment, the jet hole 142 is opened through the wall part of the support column 141, and the intersection between the jet hole 142 and the peripheral surface of the support column 141 is not a straight edge, but is inwardly recessed to form a smooth arc transition surface (for example, in the form of a horn mouth / circular arc chamfer) When jetting, the airflow is ejected from the jet hole under the guidance of the arc transition to form a stable jet beam with lighter wall-attached separation, smaller contraction, and weaker shear. Even if the jet direction is inclined at an angle relative to the end surface as described above, the arc transition can also avoid the turbulence detachment and back suction phenomenon caused by sharp edges, so that the jet flow is more easily inserted into the narrow gap and relieved in the narrow gap near the device and the ground contact belt.

[0086] In at least one embodiment of the present application, the connecting bracket 110 further comprises: The ear 150 is arranged on the side of the connecting plate 111 away from the grabbing assembly 120, and a communication hole 1501 for connecting with an external hook is arranged on the ear 150.

[0087] Please refer to Figures 1-6 In the present embodiment, the ear 150 and the connecting plate 111 are fixed by integral molding or full penetration welding, and the communication hole 1501 is arranged thereon for reliable connection with an external hook. The ear 150 is arranged vertically relative to the plane of the connecting plate 111, and the hole edge of the communication hole 1501 is rounded or horn mouth chamfered to facilitate quick positioning of the hook and uniform force bearing.

[0088] It should be noted that the ear 150 is generally a triangular plate structure, and the communication hole 1501 is a through hole.

[0089] In at least one embodiment of the present application, the grabbing assembly 120 comprises: A hanger 123 is rotatably connected to the connecting plate 111 at one end and has a plurality of hanger holes 1231 at the other end. Each grabbing jaw 122 is provided with a hanger ring 124, and each hanger ring 124 penetrates through a corresponding hanger hole 1231.

[0090] On both sides of the connecting plate 111, two grabbing jaws 122 on the same side are rotatably connected.

[0091] Between the two groups of grabbing jaws 122 on both sides, a fixing rod 125 is arranged between the two groups of grabbing jaws 122.

[0092] Please refer to Figures 1-6 In this embodiment, the hanger holes 1231 can be arranged in a straight line or an arc, so as to select appropriate hole positions according to different equipment shapes, so that each grabbing jaw 122 obtains reasonable geometric positions and foot point spacings in the circumferential and radial directions.

[0093] On both sides of the connecting plate 111, two grabbing jaws 122 on each side are rotatably connected to each other to form a linkage pair on the same side, so that they can slightly open and close around the rotation shaft and form a stable triangular or quadrilateral support geometry when clamping.

[0094] The fixing rod 125 is arranged between the two groups of grabbing jaws 122 on both sides to maintain the distance and relative attitude between the two sides during clamping and resist lateral opening and twisting.

[0095] Before lifting, the hanger 123 is swung out from below the connecting plate 111, and appropriate hole positions are selected to position each hanger ring 124, and then the operator drives the grabbing jaws 122 to close to achieve holding of the edge or reinforced part of the equipment.

[0096] The same side rotatable connection allows the two jaws to still adaptively fit when there is a local geometric error or a change in the wrap angle. The fixing rod 125 connects the two sides into a whole to limit the relative yaw and twist. The rotational freedom between the hanger 123 and the connecting plate 111 allows the grabbing jaw 122 group to automatically conform to the stress direction and the direction of gravity during lifting and pre-lifting, so as to keep consistent with the rhythm of jetting and pre-lifting, thereby reducing local stress and attitude disturbance caused by geometric mismatch and load transients.

[0097] It should be noted that the hanger 123 is generally in the form of a ring-shaped hoop structure.

[0098] Any combination of the technical features in the above embodiments can be made, and for the sake of brevity, not all possible combinations are described above, however, as long as the combination of the technical features does not exist in contradiction, it shall be considered within the scope of the present disclosure.

[0099] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it shall not be understood as a limitation on the patent scope of the present application. It shall be pointed out that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these shall be within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
