Description

Technical Field

[0001] The utility model relates to the field of cranes, in particular to a crane operation auxiliary device. Background Technique

[0002] A crane, also known as a hoist, is a lifting and handling machine widely used in ports, workshops, power plants, construction sites and other places; as a kind of lifting machinery, its main function is to vertically lift and horizontally transport heavy objects within a certain range.

[0003] The working principle of a bridge crane is mainly as follows: the traveling crane can move along the track of the main beam to the position above the goods, the crane hook descends to the position of the goods to be lifted, the crane hook connects and fixes the goods through a sling, and finally the goods leave the ground as the crane hook rises and are lifted to the target position.

[0004] When operating an existing crane, generally, the traveling crane is controlled to drive the hook to move to a specified position. During use and observation, it is found that when the traveling crane moves too fast, the hook will shake under the action of inertia after reaching the end point, and it takes extra working time to adjust it, increasing the working time required for the hook to lift an object.

[0005] Therefore, in view of the above problems, a crane operation auxiliary device is proposed. Content of the Utility Model

[0006] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background technique.

[0007] The technical solution adopted by the utility model to solve its technical problems is as follows: A crane operation auxiliary device of the utility model includes a track, and a traveling crane is slidably connected to the middle of the track; a steel wire rope is installed at the bottom of the traveling crane; a hook is installed in the middle of the steel wire rope; a fixing plate is fixedly connected to the middle of the hook; a plurality of sliding grooves are opened in the middle of the fixing plate; a plurality of springs are fixedly connected to the middle of the fixing plate; the end of the spring is fixedly connected with a slider; the slider and the sliding groove are slidably connected; a counterweight is fixedly connected to the middle of the slider; the counterweight will drive the slider to slide along the sliding groove and apply gravity to the fixing plate and the hook, realizing the quick leveling of the hook by the device, so that the hook can quickly be in a balanced state after moving, and reducing the adjustment time required due to the shaking of the hook.

[0008] Preferably, a plurality of limiting plates are fixedly connected to the top of the fixing plate; the limiting plates and the sliders are arranged correspondingly; a buffer pad is fixedly connected to the middle of the limiting plate; through the combined action of the limiting plate and the buffer pad, the limiting plate will limit the moving distance of the slider, reducing the situation that the spring is stretched too long with the slider and causing excessive deformation, playing a protective role for the spring. At the same time, the buffer pad will absorb the impact generated when the slider collides with the limiting plate, reducing the damage suffered by the slider due to the collision and prolonging the service life of the slider.

[0009] Preferably, a plurality of second magnets are fixedly connected to the middle of the slider; a plurality of first magnets are fixedly connected to the middle of the limiting plate; the first magnets and the second magnets are arranged correspondingly; when the slider moves towards the limiting plate, the distance between the second magnet and the first magnet will also shorten, and the second magnet will be subjected to the repulsive force of the first magnet, so that the slider will be subjected to the repulsive force of the second magnet and the first magnet when sliding, slowing down the sliding speed of the slider and reducing the impact generated when the slider collides with the limiting plate.

[0010] Preferably, a runner is rotatably connected to the bottom of the slider; the runner is in contact with the chute; when the slider slides along the chute, the runner will also come into contact with the chute, and the runner will rotate under the action of friction, converting the sliding friction between the slider and the chute into rolling friction, reducing the loss caused by the friction between the slider and the chute.

[0011] Preferably, a plurality of sponges are fixedly connected to the middle of the runner; the sponges are arranged in an inclined and staggered manner; when the runner rotates along the chute, the sponges will also come into contact with the chute, and the sponges will remove impurities such as dust attached to the inner wall of the chute. Because the sponges are arranged in an inclined and staggered manner, the contact area between the sponges and the chute is increased, improving the smoothness and cleanliness of the chute surface, and further reducing the frictional force between the slider and the chute.

[0012] Preferably, a plurality of fixing rods are fixedly connected to the top of the fixing plate; a ring is fixedly connected to the top of the fixing rod; the steel wire rope is located inside the ring; when the traveling crane winds and unwinds the steel wire rope, the steel wire rope will shake due to the change in tension. When the steel wire rope shakes, it will come into contact with the ring and be limited by it, reducing the shaking amplitude of the steel wire rope and reducing the friction caused by the contact between the steel wire rope and other components.

[0013] Preferably, a plurality of balls are rotatably connected to the inner side wall of the ring; the balls are arranged in a circumferential array; lubricating oil is injected into the ring. When the steel wire rope comes into contact with the ring, it will also come into contact with the balls, and the balls will rotate under the action of friction, reducing the friction between the steel wire rope and the ring. At the same time, when the balls rotate, they will brush the lubricating oil in the ring onto the surface of the steel wire rope, realizing the lubrication of the steel wire rope by the device and reducing the friction occurring when the steel wire rope works.

[0014] The advantages of the present utility model are as follows:

[0015] 1. For an auxiliary device for crane operation according to the present utility model, the counterweight will drive the slider to slide along the chute and apply gravity to the fixed plate and the hook, realizing the quick leveling of the hook by the device, so that the hook can quickly reach a balanced state after moving, reducing the positioning error caused by the swaying of the hook.

[0016] 2. For an auxiliary device for crane operation according to the present utility model, through the combined action of the limiting plate and the buffer pad, the limiting plate will limit the moving distance of the slider, reducing the situation that the spring is stretched too long along with the slider and causing excessive deformation, playing a protective role for the spring. At the same time, the buffer pad will absorb the impact generated when the slider collides with the limiting plate, reducing the damage suffered by the slider due to the collision and prolonging the service life of the slider.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Specific embodiments are given below.

[0026] Please refer to Figures 1 to 5 As shown, in an embodiment of the present utility model, for a crane control auxiliary device, a traveling crane 12 is slidably connected to the middle of the track 1; a steel wire rope 13 is installed at the bottom of the traveling crane 12; a hook 14 is installed in the middle of the steel wire rope 13; a fixing plate 15 is fixedly connected to the middle of the hook 14; a plurality of sliding grooves 19 are opened in the middle of the fixing plate 15; a plurality of springs 16 are fixedly connected to the middle of the fixing plate 15; the end of the spring 16 is fixedly connected to a slider 17; the slider 17 and the sliding groove 19 are slidably connected; a counterweight 18 is fixedly connected to the middle of the slider 17; during operation, the traveling crane 12 can be controlled to slide along the track 1. When the traveling crane 12 moves, it will move the steel wire rope 13 and the hook 14 together. After moving to the designated position, the traveling crane 12 will pay out the steel wire rope 13 to make the hook 14 approach the object to be transported. At this time, if the moving speed of the traveling crane 12 is too fast, the hook 14 will shake under the action of inertia. When the hook 14 shakes, the counterweight 18 at the lower part of its surface will drive the slider 17 to start sliding along the sliding groove 19 under the action of gravity, and the spring 16 will also be in a stretched state. The change in the position of the counterweight 18 will cause the center of gravity of the pressure exerted by the fixing plate 15 on the hook 14 to change, so that the hook 14 will quickly reset under the action of the gravity of the counterweight 18 until it is in a vertical state. Finally, after the stable hook 14 contacts the object, the object can be hung on the surface of the hook 14 through relevant equipment or manpower to realize the lifting of the object by the device; the counterweight 18 will drive the slider 17 to slide along the sliding groove 19 and exert gravity on the fixing plate 15 and the hook 14, realizing the quick leveling of the hook 14 by the device, so that the hook 14 can quickly reach a balanced state after moving, and reducing the adjustment time required due to the shaking of the hook 14.

[0027] Please refer to Figure 2 and Figure 3As shown, a plurality of limiting plates 2 are fixedly connected to the top of the fixing plate 15; the limiting plates 2 and the slider 17 are correspondingly arranged; a buffer pad 22 is fixedly connected to the middle of the limiting plate 2; when the shaking amplitude of the lifting hook 14 is too large, the counterweight 18 at the lower part will drive the slider 17 to slide rapidly along the sliding groove 19. At this time, the spring 16 will also be rapidly stretched. When the slider 17 moves, it will come into contact with the limiting plate 2. The limiting plate 2 will limit the slider 17, reducing the situation where the spring 16 is overstretched as the slider 17 moves. At the same time, the slider 17 will first come into contact with the buffer pad 22, and the buffer pad 22 will absorb the impact generated when the slider 17 collides with the limiting plate 2, reducing the damage suffered by the slider 17 when colliding with the limiting plate 2; through the combined action of the limiting plate 2 and the buffer pad 22, the limiting plate 2 will limit the moving distance of the slider 17, reducing the situation where the spring 16 is overstretched and deformed due to the excessive stretching of the slider 17, playing a protective role for the spring 16. At the same time, the buffer pad 22 will absorb the impact generated when the slider 17 collides with the limiting plate 2, reducing the damage suffered by the slider 17 due to the collision and extending the service life of the slider 17.

[0028] Please refer to Figure 3 and Figure 4 As shown, a plurality of second magnets 32 are fixedly connected to the middle of the slider 17; a plurality of first magnets 3 are fixedly connected to the middle of the limiting plate 2; the first magnets 3 and the second magnets 32 are correspondingly arranged; when the slider 17 moves towards the limiting plate 2, the distance between the second magnet 32 and the first magnet 3 will also shorten. The second magnet 32 will be subjected to the repulsive force of the first magnet 3, so that the slider 17 will be subjected to the repulsive force of the second magnet 32 and the first magnet 3 when sliding, slowing down the sliding speed of the slider 17 and reducing the impact generated when the slider 17 collides with the limiting plate 2.

[0029] Please refer to Figure 4 and Figure 5 As shown, a runner 4 is rotatably connected to the bottom of the slider 17; the runner 4 is in contact with the sliding groove 19; when the slider 17 slides along the sliding groove 19, the runner 4 will also come into contact with the sliding groove 19. The runner 4 will rotate under the action of friction, converting the sliding friction between the slider 17 and the sliding groove 19 into rolling friction, reducing the loss of the slider 17 due to the friction with the sliding groove 19.

[0030] Please refer to Figure 5 As shown, a plurality of sponges 5 are fixedly connected to the middle of the runner 4; the sponges 5 are arranged in an inclined and staggered manner; when the runner 4 rotates along the sliding groove 19, the sponges 5 will also come into contact with the sliding groove 19. The sponges 5 will remove dust and other impurities attached to the inner wall of the sliding groove 19. Because the sponges 5 are arranged in an inclined and staggered manner, the contact area between the sponges 5 and the sliding groove 19 is increased, improving the smoothness and cleanliness of the surface of the sliding groove 19 and further reducing the friction between the slider 17 and the sliding groove 19.

[0031] Please refer to Figure 2 As shown, a plurality of fixing rods 6 are fixedly connected to the top of the fixing plate 15; a ring 62 is fixedly connected to the top of the fixing rod 6; the steel wire rope 13 is located inside the ring 62; when the traveling crane 12 winds and unwinds the steel wire rope 13, the steel wire rope 13 will shake due to the change in tension. When the steel wire rope 13 shakes, it will come into contact with the ring 62 and be limited by it, reducing the shaking amplitude of the steel wire rope 13 and reducing the friction between the steel wire rope 13 and other components due to contact.

[0032] Please refer to Figure 2 As shown, a plurality of balls 7 are rotatably connected to the inner side wall of the ring 62; the balls 7 are arranged in a circumferential array; lubricating oil is injected into the ring 62. When the steel wire rope 13 comes into contact with the ring 62, it will also come into contact with the balls 7. The balls 7 will rotate under the action of friction, reducing the friction between the steel wire rope 13 and the ring 62. At the same time, when the balls 7 rotate, they will brush the lubricating oil in the ring 62 onto the surface of the steel wire rope 13, realizing the lubrication of the steel wire rope 13 by the device and reducing the friction generated when the steel wire rope 13 works.

[0033] Working principle: By controlling the movement of the traveling crane 12 along the track 1, when the traveling crane 12 moves, it will connect the wire rope 13 and the hook 14 to move together. After moving to the designated position, the traveling crane 12 will unwind the wire rope 13 so that the hook 14 approaches the object to be transported. At this time, if the moving speed of the traveling crane 12 is too fast, the hook 14 will swing under the action of inertia. When the hook 14 swings, the counterweight 18 at the lower part of its surface will drive the slider 17 to start sliding along the chute 19 under the action of gravity, and the spring 16 will also be in a stretched state. The change in the position of the counterweight 18 will cause the center of gravity of the pressure exerted by the fixed plate 15 on the hook 14 to change, so that the hook 14 will quickly reset under the action of the gravity of the counterweight 18 until it is in a vertical state. Finally, after the stable hook 14 contacts the object, the object can be hung on the surface of the hook 14 through relevant equipment or manpower to realize the lifting of the object by the device; when the swing amplitude of the hook 14 is too large, the counterweight 18 at the lower part will drive the slider 17 to slide quickly along the chute 19. At this time, the spring 16 will also be quickly stretched. When the slider 17 moves, it will contact the limit plate 2, and the limit plate 2 will limit the slider 17 to reduce the situation of excessive stretching of the spring 16 as the slider 17 moves. At the same time, the slider 17 will first contact the buffer pad 22, and the buffer pad 22 will absorb the impact generated when the slider 17 collides with the limit plate 2 to reduce the damage suffered by the slider 17 when it collides with the limit plate 2; when the slider 17 moves towards the limit plate 2, the distance between the second magnet 32 and the first magnet 3 will also be shortened, and the second magnet 32 will be subjected to the repulsive force of the first magnet 3, so that the slider 17 will be subjected to the repulsive force of the second magnet 32 and the first magnet 3 when it slides, slowing down the sliding speed of the slider 17; when the slider 17 slides along the chute 19, the runner 4 will also contact the chute 19, and the runner 4 will rotate under the action of friction, converting the sliding friction between the slider 17 and the chute 19 into rolling friction; when the runner 4 rotates along the chute 19, the sponge 5 will also contact the chute 19, and the sponge 5 will remove dust and other impurities attached to the inner wall of the chute 19. Because the sponge 5 is arranged in an inclined and staggered manner, the contact area between the sponge 5 and the chute 19 is increased, improving the smoothness and cleanliness of the surface of the chute 19; when the traveling crane 12 winds and unwinds the wire rope 13, the wire rope 13 will swing due to the change in tension. When the wire rope 13 swings, it will contact the ring 62 and be limited by it, reducing the swing amplitude of the wire rope 13; lubricating oil is injected into the ring 62. When the wire rope 13 contacts the ring 62, it will also contact the ball 7. The ball 7 will rotate under the action of friction, reducing the friction between the wire rope 13 and the ring 62. At the same time, when the ball 7 rotates, it will brush the lubricating oil in the ring 62 onto the surface of the wire rope 13 to realize the lubrication of the wire rope 13 by the device.
