Description

Technical Field

[0001] The invention relates to the field of hoisting equipment, and in particular to an anti-swaying stable suspension device. Background Art

[0002] During the processing, if the object is large, it is impossible to move it manually. In order to facilitate the movement of the object, it is usually necessary to use a suspension device to lift the object. After the object is lifted, it will shake due to external force or inertia, which may cause safety accidents.

[0003] To this end, Chinese patent CN202110471066.9 discloses a heavy object lifting equipment for road and bridge construction with anti-sway function. Its design is novel. When in use, the cargo to be lifted is hooked with a lifting hook, and the lifting assembly is started to lift the heavy object. Under the action of the stabilizing assembly, shaking is prevented during the lifting process to reduce construction risks. At the same time, when hoisted to a certain height, the lifting assembly is driven by the horizontal motion mechanism to cause lateral displacement in the horizontal position. At the same time, the horizontal motion mechanism drives the following mechanism to work through the No. 1 bevel gear set, and the following mechanism drives the stabilizing assembly to follow the lifting assembly to move synchronously, so that a certain stability can be maintained during horizontal lifting. The structure is simple and practical.

[0004] However, it requires a stabilizing component to move with the object, and can only reduce the object's shaking amplitude but cannot eliminate the object's shaking. Moreover, when the object is suspended for a long time, there is still a risk of the rope breaking. Once the rope breaks, the object falls and causes a safety accident. Summary of the invention

DETAILED DESCRIPTION

[0042] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0043] like Figure 1-10 As shown:

[0044] A sway-proof stable suspension device comprises a frame 1 and a hoisting mechanism 2, wherein the hoisting mechanism 2 comprises a steel cable 2a, a hook 2b and a first lifting assembly 2c for controlling the retraction and extension of the steel cable 2a, wherein the two ends of the steel cable 2a are respectively fixedly connected to the first lifting assembly 2c and the hook 2b, and the first lifting assembly 2c is installed on the frame 1; and further comprises an anti-sway mechanism 3, wherein the anti-sway mechanism 3 comprises a first mounting seat 3a, a docking block 3b, a matching block 3c and a connecting assembly 3d, wherein the first mounting seat 3a is installed on the frame 1, a fixed pulley 3a1 is rotatably mounted on the first mounting seat 3a, the docking block 3b is fixedly mounted on the first mounting seat 3a, the matching block 3c is fixedly connected to the hook 2b, and the connecting assembly 3d comprises a clamping block 3d1 and a first elastic member 3d2, the clamping block 3d1 is slidably mounted on the docking block 3b, and the two ends of the first elastic member 3d2 are respectively fixedly connected to the docking block 3b and the clamping block 3d1.

[0045] Based on the above embodiments, the technical problem that the present application intends to solve is how to avoid safety accidents caused by the shaking of objects during the hoisting process. To this end, the present application realizes the function of stably moving the object after the object is hoisted through the frame 1, the hoisting mechanism 2 and the anti-sway mechanism 3, and solves the defect that after the traditional suspension device hoists the object, the object shakes due to the influence of external force or inertia, causing safety accidents. The first lifting component 2c is electrically connected to the controller; the operator first sends a signal to the first lifting component 2c through the controller, and the first lifting component 2c controls the steel cable 2a to extend downward, and then hangs the object on the steel cable 2a through the hook 2b, and then sends a signal to the first lifting component 2c through the controller to lift the object. When the hook 2b continues to move upward, it will drive the matching block 3c to move upward. When the docking block 3b and the matching block 3c are in contact, the clamping block 3d1 is squeezed by the docking block 3b and provides pressure to the first elastic member 3d2. The first elastic member 3d2 is shortened after being subjected to pressure, so that the clamping block 3d1 slides into the docking block 3b, and then the docking block 3b and the matching block 3c cooperate. The clamping block 3d1 slides out of the docking block 3b under the elastic force of the first elastic member 3d2, so that the docking block 3b and the matching block 3c are connected, and the position of the object is fixed by a rigid connection, thereby preventing the object from shaking and shifting, and greatly improving the stability of the object's movement and suspension.

[0046] Furthermore, the present application still has the defect that the docking block 3b and the matching block 3c cannot be separated by remote control. In order to solve this problem, Figure 4 As shown:

[0047] The connection assembly 3d also includes an electromagnetic element 3d3, which is fixedly mounted on the docking block 3b. Both ends of the first elastic member 3d2 are respectively fixedly connected to the electromagnetic element 3d3 and the clamping block 3d1, and the clamping block 3d1 is made of metal affected by magnetic force.

[0048] Based on the above embodiments, the technical problem that the present application wants to solve is how to remotely control the separation of the docking block 3b and the matching block 3c. To this end, the present application realizes the function of attracting the card block 3d1 to slide into the docking block 3b after power is turned on through the electromagnetic element 3d3. The electromagnetic element 3d3 is electrically connected to the controller; the operator first lifts the object through the steel cable 2a, the hook 2b and the first lifting component 2c, and then fixes the position of the object through the cooperation of the docking block 3b, the matching block 3c and the connecting component 3d. When the operator needs to put the object down, the controller first sends a signal to the electromagnetic element 3d3, so that the electromagnetic element 3d3 is powered on to generate magnetism, thereby attracting the card block 3d1 to slide into the docking block 3b through magnetic force, disconnecting the connection between the docking block 3b and the matching block 3c, and then the first lifting component 2c is used to release the line at a uniform speed, and the object moves downward under the action of gravity, so that the operator can take down the object.

[0049] Furthermore, the present application still has the defect that the object must be moved to the first mounting seat 3a to fix the position. In order to solve this problem, Figure 3 , Figure 5 and Figure 6 As shown:

[0050] The anti-sway mechanism 3 also includes a second lifting component 3e, which includes a fixed hinge shaft 3e1, a sliding hinge seat 3e2, a connecting rod 3e3, a first screw 3e4 and a first rotation driver 3e5. The fixed hinge shaft 3e1 and the sliding hinge seat 3e2 are each provided with multiple and one-to-one correspondence. The multiple fixed hinge shafts 3e1 are respectively fixedly mounted on the first mounting seat 3a and the second mounting seat 3f1. There are multiple connecting rods 3e3, and the multiple connecting rods 3e3 are hinged to each other to form a scissor-fork structure. The two ends of the scissor-fork structure are respectively hinged to the first mounting seat 3a and the second mounting seat 3f1 through the fixed hinge shaft 3e1 and the sliding hinge seat 3e2. The first screw 3e4 is rotatably mounted on the first mounting seat 3a. The first screw 3e4 is threadedly connected to the sliding hinge seat 3e2. The first rotation driver 3e5 is fixedly mounted on the first mounting seat 3a, and the driving end of the first rotation driver 3e5 is transmission connected to the first screw 3e4.

[0051] Based on the above embodiments, the technical problem that the present application wants to solve is how to further reduce the working restrictions of the anti-sway mechanism 3. To this end, the present application realizes the function of driving the docking block 3b to rise and fall by fixing the hinge shaft 3e1, the sliding hinge seat 3e2, the connecting rod 3e3, the first screw 3e4 and the first rotation driver 3e5. The first rotation driver 3e5 is preferably a servo motor, which is electrically connected to the controller; the operator first sends a signal to the first lifting component 2c through the controller, and the first lifting component 2c controls the steel cable 2a to extend downward, and then hangs the object on the steel cable 2a through the hook 2b, and then sends a signal to the first lifting component 2c through the controller to lift the object. When the hook 2b continues to move upward, it will drive the matching block 3c to move upward. When the object rises to the specified height, it stops rising. At this time, the operator sends a signal to the servo motor through the controller. After receiving the signal, the servo motor drives the first screw 3e4 to rotate, and the first screw 3e4 drives The sliding hinge seat 3e2 threadedly connected to it slides, thereby extending the scissor-type structure and driving the docking block 3b to move downward. When the docking block 3b and the matching block 3c come into contact, the clamping block 3d1 is squeezed by the docking block 3b and provides pressure to the first elastic member 3d2. The first elastic member 3d2 is shortened after being subjected to the pressure, so that the clamping block 3d1 slides into the docking block 3b. Then the docking block 3b and the matching block 3c cooperate. The clamping block 3d1 slides out of the docking block 3b under the elastic force of the first elastic member 3d2, so that the docking block 3b and the matching block 3c are connected, thereby fixing the object in the specified position and preventing the object from shaking in the air through the connection of the scissor-type structure.

[0052] Furthermore, the present application still has the defect that after the docking block 3b and the matching block 3c are connected, the matching block 3c does not provide an upward traction force to the object. In order to connect the docking block 3b and the matching block 3c, the docking block 3b may even provide a downward pressure on the object. The steel cable 2a may break after being subjected to force for a long time, causing the object to fall. In order to solve this problem, Figure 3 and Figure 7 As shown:

[0053] The anti-sway mechanism 3 also includes a buffer component 3f, which includes a second mounting seat 3f1, a second elastic member 3f2 and a guide hole 3f3. The two ends of the second elastic member 3f2 are respectively fixedly connected to the second mounting seat 3f1 and the docking block 3b. The guide hole 3f3 is fixedly arranged on the docking block 3b and the second mounting seat 3f1 for allowing the steel cable 2a to pass through. The connecting component 3d is installed on the docking block 3b.

[0054] Based on the above embodiments, the technical problem that the present application intends to solve is how to make the docking block 3b provide an upward traction force for the object to reduce the pressure of the steel cable 2a. To this end, the present application realizes the function of reducing the pressure of the steel cable 2a through the second mounting seat 3f1, the second elastic member 3f2 and the guide hole 3f3. The operator first lifts the object through the steel cable 2a, the hook 2b and the first lifting assembly 2c, and then connects the docking block 3b and the matching block 3c through the cooperation of the docking block 3b, the matching block 3c, the connecting assembly 3d and the second lifting assembly 3e. When the docking block 3b and the matching block 3c are connected, the controller sends a signal to the first rotary driver 3e5, and the first rotary driver 3e5 drives the docking block 3b to rise a certain distance, and then the elastic force of the second elastic member 3f2 provides traction for the object, thereby reducing the pressure of the steel cable and further improving the stability of the object suspension.

[0055] Furthermore, the present application still has the defect that once the steel cable 2a breaks, the elastic force provided by the second elastic member 3f2 cannot support the object to be suspended, and the object will still fall. In order to solve this problem, Figure 7 As shown:

[0056] The buffer assembly 3f also includes a guide rod 3f4 and a limit block 3f5. The guide rod 3f4 is fixedly mounted on the docking block 3b. The guide rod 3f4 is slidably matched with the second mounting seat 3f1. The limit block 3f5 is fixedly mounted on the top of the guide rod 3f4.

[0057] Based on the above embodiments, the technical problem that the present application intends to solve is how to support an object when the steel cable 2a breaks. To this end, the present application realizes the function of preventing the object from falling through the guide rod 3f4 and the limit block 3f5. Once an abnormal situation occurs, causing the steel cable 2a to break, the elastic force provided by the second elastic member 3f2 alone cannot support the object to continue to hang. To this end, a guide rod 3f4 and a limit block 3f5 are provided on the docking block 3b. When the steel cable 2a suddenly breaks, the object, the hook 2b and the docking block 3b will move downward rapidly under the action of gravity. When the limit block 3f5 contacts the second mounting seat 3f1, the object is supported by the guide rod 3f4 and the limit block 3f5 to prevent the object from continuing to slide down.

[0058] Furthermore, the present application still has the defect that the operator needs to manually control the traction force provided by the docking block 3b to the object. In order to solve this problem, Figure 7 As shown:

[0059] The buffer assembly 3f also includes a first pressure sensor 3f6, which is fixedly mounted on the second mounting seat 3f1, and two ends of the second elastic member 3f2 are fixedly connected to the first pressure sensor 3f6 and the docking block 3b respectively.

[0060] Based on the above embodiments, the technical problem that the present application intends to solve is how to further improve the automation of the stable suspension device. To this end, the present application realizes the function of real-time detection of the traction force provided by the docking block 3b to the object through the first pressure sensor 3f6. The first pressure sensor 3f6 is electrically connected to the controller; the operator first lifts the object through the steel cable 2a, the hook 2b and the first lifting component 2c, and then connects the docking block 3b and the matching block 3c through the cooperation of the docking block 3b, the matching block 3c, the connecting component 3d and the second lifting component 3e. When the docking block 3b and the matching block 3c are connected, the controller sends a signal to the first rotary driver 3e5, and the first rotary driver 3e5 drives the docking block 3b to rise a certain distance, and then the elastic force of the second elastic member 3f2 provides traction for the object, and the traction force is monitored in real time through the first pressure sensor 3f6, so that the second elastic member 3f2 provides a specified traction force to the object.

[0061] Furthermore, in order to solve the technical problem of how the first lifting assembly 2c drives the steel cable 2a to be retracted and extended, as Figure 2 , Figure 8 and Fig. 9 As shown:

[0062] The first lifting assembly 2c includes a first rotating shaft 2c1, a focusing cylinder 2c2 and a second rotating driver 2c3. The first rotating shaft 2c1 is rotatably mounted on the frame 1. The focusing cylinder 2c2 is fixedly sleeved on the first rotating shaft 2c1. The steel cable 2a is fixedly connected to the focusing cylinder 2c2. The second rotating driver 2c3 is fixedly mounted on the frame 1. The driving end of the second rotating driver 2c3 is transmitted to the first rotating shaft 2c1.

[0063] Based on the above embodiments, the technical problem that the present application wants to solve is how to drive the steel cable 2a to be retracted and released. To this end, the present application realizes the function of driving the steel cable 2a to be retracted and released through the first rotating shaft 2c1, the gathering cylinder 2c2 and the second rotating driver 2c3. The second rotating driver 2c3 is electrically connected to the controller; the operator first sends a signal to the second rotating driver 2c3 through the controller, and the second rotating driver 2c3 drives the first rotating shaft 2c1 to rotate, and the first rotating shaft 2c1 drives the gathering cylinder 2c2 to rotate, and the hook 2b moves downward under the action of gravity, and then the object is hung on the steel cable 2a through the hook 2b, and then the controller sends a signal to the first lifting component 2c to lift the object, completing the suspension of the object.

[0064] Furthermore, the present application still has the defect that the movement of the object cannot be controlled after the object is hung. In order to solve this problem, Figure 2 and Fig. 9 As shown:

[0065] The frame 1 also includes a linear drive component 2d, which includes a slide groove 2d1, a third rotation driver 2d2 and a second screw 2d3. The slide groove 2d1 is fixedly set on the frame 1, and the first mounting seat 3a is slidably matched with the slide groove 2d1. The third rotation driver 2d2 is fixedly mounted on the frame 1, and the second screw 2d3 is rotatably mounted on the frame 1. The second screw 2d3 is threadedly connected to the first mounting seat 3a, and the driving end of the third rotation driver 2d2 is transmission-connected to the second screw 2d3.

[0066] Based on the above embodiments, the technical problem that the present application wants to solve is how to move objects quickly. To this end, the present application realizes the function of automatically controlling the movement of objects through the slide 2d1, the third rotary driver 2d2 and the second screw 2d3. The third rotary driver 2d2 is preferably a servo motor, which is electrically connected to the controller; the operator first sends a signal to the second rotary driver 2c3 through the controller, and the second rotary driver 2c3 drives the first rotary shaft 2c1 to rotate, and the first rotary shaft 2c1 drives the convergence tube 2c2 to rotate, and the hook 2b moves downward under the action of gravity, and then the object is hung on the steel cable 2a through the hook 2b, and then the controller sends a signal to the first lifting assembly 2c to lift the object, and then the operator sends a signal to the third rotary driver 2d2 through the controller, and the third rotary driver 2d2 drives the second screw 2d3 to rotate, and the second screw 2d3 drives the first mounting seat 3a threadedly connected to it to move along the slide 2d1, thereby moving the object to the specified position.

[0067] Furthermore, the present application still has the defect that the first mounting seat 3a will be subjected to a large pressure after hoisting the object, which makes it easy to be damaged. In order to solve this problem, Figure 5 and Fig. 9 As shown:

[0068] The linear drive assembly 2d also includes a second rotating shaft 2d4 and a supporting wheel 2d5. The second rotating shaft 2d4 is rotatably mounted on the first mounting seat 3a. The second rotating shaft 2d4 is slidably matched with the frame 1, and the supporting wheel 2d5 is sleeved on the second rotating shaft 2d4.

[0069] Based on the above embodiments, the technical problem that the present application intends to solve is how to stably support the first mounting seat 3a. To this end, the present application realizes the function of supporting the first mounting seat 3a through the second rotating shaft 2d4 and the supporting wheel 2d5. The first mounting seat 3a is supported and stabilized by the supporting wheel 2d5. When the first mounting seat 3a is driven to move by the linear drive assembly 2d, the supporting wheel 2d5 will roll along the extension direction of the slide groove 2d1. By rolling instead of sliding between the first mounting seat 3a and the frame 1, energy loss can be further reduced, and the energy utilization rate of the stable suspension device can be improved.

[0070] Furthermore, the present application still has the defect that the operator needs to judge the shaking of the wire rope 2a by himself. In order to solve this problem, Fig.10 As shown:

[0071] The hoisting mechanism 2 further comprises a second pressure sensor 2e, which is fixedly mounted on the first mounting seat 3a, and the bottom of the second pressure sensor 2e is fixedly connected to the hook 2b.

[0072] Based on the above embodiments, the technical problem that this application wants to solve is how to further reduce the labor intensity of operators. To this end, this application realizes the function of automatically judging the shaking of the steel cable 2a through the second pressure sensor 2e. The second pressure sensor 2e is electrically connected to the controller; the operator first lifts the object through the steel cable 2a, the hook 2b and the first lifting component 2c. Once the object shakes under the influence of external force or inertia, the pressure value sensed by the second pressure sensor 2e will fluctuate. The greater the fluctuation of the pressure value, the more severe the object shakes, which makes it easier for the operator to judge the shaking of the object.
