Description

Technical Field

[0001] The invention belongs to the technical field of mechanical equipment, in particular to a device for enhancing the safety factor in the process of lifting a rotor. Background Art

[0002] The device that enhances the safety factor during the lifting rotor operation is a combination of safety devices of the lifting equipment, mainly including lifting height limiters, lifting weight limiters, deflection adjustment and display devices, and non-contact sensor safety devices. These devices can limit the height and weight of the lifting equipment, prevent excessive deflection, monitor in real time and avoid collision with obstacles, thereby effectively ensuring the safety of the lifting rotor operation.

[0003] In the prior art, during lifting, a special lifting device is firmly connected to the heavy object, and a balancing adjustment mechanism is used to keep the rotor in a horizontal state. During the lifting process, the safety monitoring device collects data such as the force condition, lifting height, and speed in real time. Once abnormal data is found, such as the force exceeds the safety range or the lifting speed is abnormal, an alarm will be issued immediately. At the same time, the safety braking system will be on standby at all times. When an emergency occurs, such as abnormal shaking or excessive descent, the braking system will respond quickly to suspend the lifting process to avoid safety accidents such as falling and collision of heavy objects. The lifting operation will not be continued until the abnormal situation is eliminated.

[0004] There are still some problems in the actual application of the above scheme. When the equipment completes the preparatory work before lifting, the heavy object will be gradually lifted into the air as the machine is pulled up. When the heavy object is lifted into the air, it will shake due to the influence of factors such as wind, and the shaking will cause the center of gravity of the heavy object to shift, so that it is no longer located on the support point of the sling or sling. When the center of gravity shifts to a certain extent, the heavy object will lose balance, thereby increasing the risk of slipping. Secondly, the added limit clamping mechanism will directly contact the ground when stored after work, and contact with the ground will be more susceptible to collisions from external factors. In daily warehouse activities, such as forklifts carrying other goods and people walking around, the device will be accidentally hit, and this collision will cause the device to deform and damage, thereby affecting its limit function.

[0005] To this end, the present invention provides a device for enhancing the safety factor during the operation of lifting a rotor. Summary of the invention

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] Embodiment 1

[0036] like Figures 1 to 9 As shown, a device for enhancing the safety factor during the operation of lifting a rotor according to an embodiment of the present invention comprises a lifting device 1, wherein the lifting device 1 comprises a lifting hook 101, wherein the outer ring surface of the lifting hook 101 is provided with a steel wire rope 102, wherein one end of the steel wire rope 102 is fixedly connected to a dynamometer 103, wherein the other end of the dynamometer 103 is fixedly connected to a hand chain hoist 104, wherein the other end of the hand chain hoist 104 is fixedly connected to a shoulder pole 105, wherein a hook fixing hole 106 is provided inside the shoulder pole 105, wherein a hook fixing pin 107 is inserted inside the hook fixing hole 106, wherein the outer ring surface of the steel wire rope 102 is provided with a main lifting rope 108, and a reciprocating limiting mechanism 2 is provided at the bottom of the lifting device 1;

[0037] The reciprocating limiting mechanism 2 includes a fixed shell 201 fixedly arranged on the side of the shoulder pole 105, and a groove is opened inside the fixed shell 201. A sliding block 204 is slidably arranged in the groove of the fixed shell 201. There are two groups of sliding blocks 204. The relative sliding of the two groups of sliding blocks 204 can limit the side of the lifted heavy object, avoiding the center of gravity shift during lifting, thereby improving the safety of the device.

[0038] Specifically, when the equipment completes the preparatory work before lifting, the heavy object will be gradually lifted into the air as the machine is pulled up. When the heavy object is lifted into the air, it will shake due to the influence of factors such as wind, and the shaking will cause the center of gravity of the heavy object to shift, so that it is no longer located at the supporting point of the sling or sling. When the center of gravity shifts to a certain extent, the heavy object will lose balance, thereby increasing the risk of slipping;

[0039] Therefore, the present invention solves this problem by setting a corresponding structure. The device for enhancing the safety factor during the operation of lifting the rotor described in the present invention, when it is necessary to lift the heavy object, the staff will put the main lifting rope 108 and the wire rope 102 onto the wire rope 102, and at the same time, the dynamometer 103 and the hand chain hoist 104 are installed in sequence and connected to the shoulder pole 105 through the hook. At this time, the heavy object is hung on the two sets of hooks at the bottom of the shoulder pole 105 through the rope, and the hand chain hoist 104 is used to adjust the pointer indication scale of the dynamometer 103 during the adjustment process, so that the pointer scales of the dynamometers 103 on both sides are consistent within the safety range, so that the shoulder pole 105 is kept horizontal, and the hook fixing pin 107 is adjusted according to the center of gravity of the heavy object to be inserted into any set of hook fixing holes 1 06 to adjust the position of the hook so that the center of gravity of the entire hoisted object is concentrated on the main wire rope directly below the main hook, ensuring the safety of the lifting operation. However, as the equipment completes the preparatory work before lifting, the heavy object will be gradually lifted into the air as the machine is pulled up. When the heavy object is lifted into the air, it will shake due to the influence of factors such as wind, and the shaking will cause the center of gravity of the heavy object to shift, so that it is no longer located on the supporting point of the sling or sling. When the center of gravity shifts to a certain extent, the heavy object will lose balance, thereby increasing the risk of slipping. At this time, the relative movement of the sliding block 204 sliding inside the fixed shell 201 fixed on both sides of the shoulder pole 105 can limit the lifted heavy object to avoid the center of gravity shift during lifting, thereby improving the safety of the device.

[0040] Embodiment 2

[0041] like Figures 1 to 9 As shown in Comparative Example 1, another embodiment of the present invention is:

[0042] like Figure 5 As shown, in this embodiment, the side wall of the groove of the fixed shell 201 is fixedly connected to the external driving source 202, the output shaft of the external driving source 202 is fixedly connected to the bidirectional screw 203, the outer ring surface of the bidirectional screw 203 is threadedly connected to the sliding block 204, a limiting rod 205 is arranged inside the sliding block 204, the sliding block 204 is slidably connected to the outer ring surface of the limiting rod 205, and the side wall of the lower part of the fixed shell 201 is fixedly connected to the first guide block 206.

[0043] Specifically, when it is necessary to lift a heavy object, the external driving source 202 is started. At this time, the output shaft of the external driving source 202 will drive the bidirectional screw 203 fixed thereto to rotate, and at the same time drive the two groups of sliding blocks 204 threadedly connected thereto to move synchronously. Since the sliding blocks 204 slide on the outer ring surface of the limiting rod 205, and both ends of the limiting rod 205 are fixed on the side walls of the groove of the fixed shell 201, when the bidirectional screw 203 rotates, the two groups of sliding blocks 204 will move synchronously toward the middle of the bidirectional screw 203, and at the same time drive the remaining mechanisms to move synchronously, thereby limiting the lifted heavy object, thereby preventing the heavy object from swinging in the air, and reducing the risk of collision with surrounding buildings or construction workers.

[0044] like Figure 6 As shown, a rotational offset mechanism 3 for flipping is disposed on the side of the reciprocating limiting mechanism 2 of this embodiment. The rotational offset mechanism 3 includes an L-shaped fixing plate 301 , and the L-shaped fixing plate 301 is fixedly connected to the side wall of the sliding block 204 .

[0045] like Figure 6 and Fig. 9 As shown, the L-shaped fixed plate 301 in this embodiment is composed of a vertical plate and a transverse plate, the side of the vertical plate of the L-shaped fixed plate 301 is fixedly connected with a second guide block 302, the inside of the transverse plate of the L-shaped fixed plate 301 is fixedly connected with an electric cylinder 303, the output end of the electric cylinder 303 is fixedly connected with a connecting block 304, the inside of the connecting block 304 is rotatably connected with a guide column 308, the outer ring surface of the guide column 308 is fixedly connected with a rotating plate 309, and the side of the rotating plate 309 close to the outer ring surface is fixedly connected with a sliding column 310.

[0046] Specifically, when the reciprocating limit mechanism 2 completes its work and is stored, the external driving source 202 is started to drive the two groups of sliding blocks 204 to move to the initial state, and the electric cylinder 303 is started. At this time, the output shaft of the electric cylinder 303 will drive the connecting block 304 to move upward along the guide of the second guide block 302, and at the same time drive the guide column 308 to move synchronously. Since the rotating plate 309 is fixed on the outer ring surface of the guide column 308, when the connecting block 304 moves upward, it will drive the rotating plate 309 to move synchronously, and at the same time, it will also drive the sliding column 310 to move synchronously. The movement of the connecting block 304 can provide power support for the movement of the subsequent device.

[0047] like Figure 7 As shown, in this embodiment, the vertical plate of the L-shaped fixing plate 301 is provided with a first limiting groove 305, the side of the vertical plate of the L-shaped fixing plate 301 is provided with an arc groove 306, and the side of the vertical plate of the L-shaped fixing plate 301 is fixedly connected with a locking column 307.

[0048] like Figure 8 As shown, in this embodiment, a fixed block 311 is fixedly connected to the side of the sliding block 204 , a second limiting groove 312 is opened on the side of the fixing block 311 , and a sliding block 313 is slidably connected inside the second limiting groove 312 .

[0049] like Figure 8 As shown, in this embodiment, the slider 313 is fixedly connected to a connecting column 314, and the outer ring surface of the other end of the connecting column 314 is rotatably connected to a limiting plate 315.

[0050] Specifically, when the guide column 308 moves upward along the guide of the first limiting groove 305, it will drive the rotating plate 309 to move synchronously, and while moving, the teeth on the rotating plate 309 will gradually engage with the multiple groups of positioning columns 307 fixed on the vertical plate of the L-shaped fixed plate 301, and will rotate at the same time, and while rotating, it will drive the guide column 308 to rotate around its central axis, and while rotating, the sliding column 310 fixed on the side of the rotating plate 309 will slide into the arc groove 306, and when the tooth structure on one side of the rotating plate 309 is engaged with the multiple groups of positioning columns 307, the sliding column 310 fixed on one side of the rotating plate 309 will slide to the arc-shaped top end of the arc groove 306, and continue to move along the guide of the arc groove 306 At the same time, the slider 313 will also move upward along the guide of the second limiting groove 312, and while moving, it will rotate synchronously with the rotation of the rotating plate 309. When the rotating plate 309 disengages from the locking column 307, the side with the teeth will face downward, and the sliding column 310 will slide out of the arc groove 306 and enter the first limiting groove 305. At this time, the limiting plate 315 fixed on the guide column 308 will flip over to the top of the shoulder pole 105. Through the setting of the fixed block 311, the second limiting groove 312, the slider 313 and the connecting column 314, the stability of the limiting plate 315 during operation can be improved, thereby reducing the accidental collision or friction of the limiting plate during storage, thereby extending the service life of the limiting plate 315.

[0051] Working principle: when it is necessary to lift a heavy object, start the external driving source 202. At this time, the output shaft of the external driving source 202 will drive the bidirectional screw 203 fixed thereto to rotate, and at the same time drive the two groups of sliding blocks 204 threadedly connected thereto to move synchronously. Since the sliding blocks 204 slide on the outer ring surface of the limiting rod 205, and both ends of the limiting rod 205 are fixed on the side walls of the groove of the fixed shell 201, when the bidirectional screw 203 rotates, the two groups of sliding blocks 204 move synchronously toward the middle of the bidirectional screw 203, and at the same time drive the remaining mechanisms to move synchronously, thereby limiting the lifted heavy object, thereby preventing the heavy object from swinging in the air, and reducing the risk of collision with surrounding buildings or construction workers.

[0052] When the reciprocating limit mechanism 2 completes its work, the external driving source 202 is started to drive the two groups of sliding blocks 204 to move to the initial state. At this time, the electric cylinder 303 is started. At this time, the output shaft of the electric cylinder 303 will drive the connecting block 304 to move upward along the guide of the second guide block 302, and drive the guide column 308 to move synchronously while moving. Since the rotating plate 309 is fixed on the outer ring surface of the guide column 308, when the connecting block 304 moves upward, it will drive the rotating plate 309 to move synchronously, and will also drive the sliding column 310 to move synchronously. The movement of the connecting block 304 can provide power support for the movement of the subsequent device.

[0053] When the guide column 308 moves upward along the guide of the first limit groove 305, it will drive the rotating plate 309 to move synchronously, and while moving, the teeth on the rotating plate 309 will gradually engage with the multiple groups of positioning columns 307 fixed on the vertical plate of the L-shaped fixed plate 301, and at the same time drive the guide column 308 to rotate around its central axis. While rotating, the sliding column 310 fixed on the side of the rotating plate 309 will slide into the arc groove 306. When the tooth structure on one side of the rotating plate 309 is engaged with the multiple groups of positioning columns 307, the sliding column 310 fixed on one side of the rotating plate 309 will slide to the arc-shaped top end of the arc groove 306 and continue to move along the guide of the arc groove 306. At the same time, the slider 313 also It will move upward along the guide of the second limiting groove 312, and rotate synchronously with the rotation of the rotating plate 309 while moving. When the rotating plate 309 disengages from the locking column 307, the side with the teeth will face downward, and the sliding column 310 will slide out of the arc groove 306 and enter the first limiting groove 305. At this time, the limiting plate 315 fixed on the guide column 308 will flip over to the top of the shoulder pole 105. Through the setting of the fixed block 311, the second limiting groove 312, the sliding block 313 and the connecting column 314, the stability of the limiting plate 315 during operation can be improved, thereby reducing the accidental collision or friction of the limiting plate during storage, thereby extending the service life of the limiting plate 315.
