Description

Technical Field

[0001] The invention relates to the technical field of cranes, in particular to a crane beam used for a crane. Background Art

[0002] A crane is a multi-action lifting machine that can lift and carry heavy objects vertically and horizontally within a certain range. It is also called an overhead crane, an overhead crane, or a crane. A bridge crane is a lifting device that is horizontally mounted above a workshop, warehouse, or material yard to lift materials. Because its two ends are located on tall concrete columns or metal brackets, it looks like a bridge. The bridge of a bridge crane runs longitudinally along the tracks laid on the elevated platforms on both sides, making full use of the space under the bridge to lift materials without being hindered by ground equipment. It is the most widely used and most numerous type of lifting machine.

[0003] When a crane is transporting goods, it usually uses a hook to fix the goods. Some cranes use double hooks. During use, it is usually necessary to adjust the distance between the double hooks according to the size of the goods. Some existing cranes usually use a motor to drive the two-way threaded rod to rotate, so that the two sliders move in opposite directions along the two-way threaded rod, thereby adjusting the position of the double hooks. However, when the goods are lifted and moved, they will swing left and right due to gravity. During the swinging process, a certain oblique force will be applied to the slider, which will increase the wear between the slider and the two-way threaded rod, affecting the service life of the device.

This arrangement is to drive the bidirectional threaded rod to rotate through the operation of the stepping motor, and the first sliding rod will limit the first slider, so that when the bidirectional threaded rod rotates, the two first sliders can be driven to move in opposite directions, the first slider drives the sleeve to move, the sleeve drives the sleeve rod to move, and the sleeve rod drives the mounting rod to move, thereby moving the wire wheel to adjust the distance between the two wire wheels.

[0006] Furthermore, a threaded rod is fixedly connected to the output end of the movable motor, and the end of the threaded rod away from the movable motor is rotatably connected to the inside of the first slide groove. A second slider is threadedly connected to the outer wall of the threaded rod, and the second slider is slidably connected to the inside of the first slide groove. This arrangement is to drive the threaded rod to rotate through the operation of the movable motor. The rotation of the threaded rod will cause the second slider to move along the threaded rod, thereby driving the adjustment mechanism to move.

[0007] Furthermore, the bottom of the second slider is fixedly connected to the top of the installation box, the top of the installation box is fixedly connected with a fixing rod, the outer wall of the fixing rod is slidably connected to the inside of the limiting groove, the inner wall of the fixing rod is fixedly connected with a connecting rod, both ends of the connecting rod are rotatably connected to rollers, the bottom of the roller is located inside the guide wheel groove, such an arrangement is to reduce the friction force when the adjusting mechanism moves by the roller, and at the same time can play a role of mobile support for the adjusting mechanism, thereby avoiding the increase of pressure between the second slider and the threaded rod due to the gravity of the moving mechanism.

[0008] Furthermore, the lifting mechanism includes a base, the bottom of the base is fixedly connected to the bottom wall of the installation box, the top of the base is fixedly connected to a servo motor, the bottom of the installation box is fixedly connected to a mounting frame, the mounting frame is rotatably connected to a rotating rod, and both ends of the rotating rod pass through the outer wall of the mounting frame and extend.

[0009] Furthermore, the front end of the rotating rod on the left side is fixedly connected to the output end of the servo motor, the outer wall of the rotating rod is fixedly connected to a take-up roller, the take-up roller is located inside the mounting frame, the rear end of the rotating rod is fixedly connected to a belt pulley, the two belt pulleys are rotatably connected by belts, and the outer wall of the take-up roller is fixedly connected to a suspension rope. When arranged in this way, in order to drive the rotating rod to rotate by the servo motor, the rotating rod drives the left belt pulley to rotate, and the left belt pulley rotates through the right belt pulley via the belt, thereby causing the two take-up rollers to rotate simultaneously.

[0010] Furthermore, the fixing mechanism includes an installation box, the top of the installation box is fixedly connected to the bottom end of the suspension rope, a second spring is fixedly connected to the top of the inside of the installation box, the bottom end of the second spring is fixedly connected to a mounting plate, the mounting plate sliding rod is connected to the inside of the installation box, a hook is fixedly connected to the bottom of the installation plate, the hook is socketed with the installation box, and a second slide groove is opened at the bottom of the installation plate.

[0011] Furthermore, a second sliding rod is fixedly connected to the inside of the second sliding groove, a third sliding block is slidably connected to the outer wall of the second sliding rod, an L-shaped rod is rotatably connected to the bottom of the third sliding block, a mounting groove is opened at the bottom of the mounting box, a support rod is fixedly connected to the inside of the mounting groove, the support rod is rotatably connected to the inside of the L-shaped rod, and a clamping ring is fixedly connected to the bottom end of the L-shaped rod, so that the second sliding rod and the third sliding block can be driven to move when the mounting plate moves, and the movement of the third sliding block will push the L-shaped rod to rotate around the support rod, so that the clamping ring fits with the hook opening.

[0012] The present invention has the following beneficial effects: The present invention drives the bidirectional threaded rod to rotate through the operation of the stepping motor. Since the first sliding bar can prevent the first sliding block from rotating, when the bidirectional threaded rod rotates, the two first sliding blocks will move in opposite directions along the first sliding bar, the first sliding block drives the sleeve to move, the sleeve drives the limit plate to move, the limit plate drives the sleeve rod to move, the sleeve rod drives the mounting rod to move along the rack, and the mounting rod drives the guide wheel to move, so that the distance between the two guide wheels can be adjusted to meet the lifting needs of goods of different lengths. At the same time, during the movement of the goods, the goods will shake left and right due to inertia, and the goods will drive the lifting rope to shake. During the shaking of the lifting rope, a certain oblique force will be applied to the guide wheel, which will be applied to the mounting rod, and the rack will play a certain supporting role on the mounting rod, thereby reducing the influence of the shaking of the goods on the first sliding block and the bidirectional threaded rod, and improving the service life of the first sliding block and the bidirectional threaded rod.

[0013] The present invention drives the threaded rod to rotate by the movement of a mobile motor. The rotation of the threaded rod causes the second slider to move along the threaded rod, and the second slider drives the adjusting mechanism to move, the adjusting mechanism drives the lifting mechanism to move, and the lifting mechanism drives the fixing mechanism to move, thereby moving the goods. At the same time, the installation box drives the fixing rod to move, the fixing rod drives the connecting rod to move, and the connecting rod drives the roller to move along the guide wheel groove, thereby improving the stability of the adjusting mechanism during movement. At the same time, multiple groups of rollers can effectively share the gravity of the adjusting mechanism and the goods, thereby improving the stability of the device. At the same time, multiple groups of rollers can effectively avoid the increase in the distance between the second slider and the threaded rod due to the gravity of the adjusting mechanism and the goods, thereby improving the service life of the second slider and the threaded rod.

[0014] The present invention drives the left rotating rod to rotate by the counterclockwise operation of the servo motor, and the left rotating rod drives the left belt pulley to rotate, and the left belt pulley drives the right belt pulley to rotate through the belt, so that the two rotating rods rotate at the same time, and the rotating rod drives the take-up roller to rotate. Because the lifting rope is wound on the surface of the take-up roller, and the lifting ropes on both sides are wound on the take-up roller in opposite directions, the two lifting ropes will be wound up at the same time when the two take-up rollers rotate counterclockwise, thereby driving the two fixing mechanisms to rise at the same time, effectively improving the stability of the goods when they are lifted.

[0015] The present invention will preferentially pull the installation box up through the lifting rope, and the rising of the installation box will drive the second spring and the support rod to rise, and the support rod will drive the L-shaped rod to rise. During the rising process of the L-shaped rod, the top end of the L-shaped rod will push the third sliding block to move backward along the second sliding block, and at the same time, the L-shaped rod will rotate around the support rod, and the bottom end of the L-shaped rod will push the clamping ring and the hook opening to move. When the mounting plate contacts the bottom of the mounting box, the clamping ring will contact the inner wall of the hook opening to form a closed space, and when the lifting rope continues to rise, the mounting box will block the mounting plate. At this time, the goods will rise as the hook has started, and due to the gravity of the goods, the clamping ring will always be in contact with the hook during the lifting process of the goods, so as to avoid the goods from being separated from the hook due to shaking, resulting in the goods falling and being damaged.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] When in use, start the stepper motor 102, and the stepper motor 102 drives the bidirectional threaded rod 103 to rotate. Because the first slide bar 104 can prevent the first slider 105 from rotating, when the bidirectional threaded rod 103 rotates, the two first sliders 105 will move in opposite directions along the first slide bar 104, and the first slider 105 drives the sleeve 106 to move, and the sleeve 106 drives the limit plate 108 to move, and the limit plate 108 drives the sleeve rod 109 to move, and the sleeve rod 109 drives the installation rod 110 to move along the rack 112, and the installation rod 110 drives the wire wheel 111 to move, so that the distance between the two wire wheels 111 can be adjusted to meet the needs of hoisting goods of different lengths. At the same time, during the movement of the installation rod 110, the installation rod 110 will push The movable sleeve rod 109 moves upward, and the sleeve rod 109 pushes the limit plate 108 to move upward. The upward movement of the limit plate will compress the first spring 107.

During the shaking of the hanging rope 307, a certain oblique force will be applied to the wire wheel 111, and the wire wheel 111 will apply it to the installation rod 110, and the rack 112 will play a certain supporting role on the installation rod 110, thereby reducing the impact of the shaking of the goods on the first slider 105 and the bidirectional threaded rod 103, and improving the service life of the first slider 105 and the bidirectional threaded rod 103. , and then hang the goods on the two hooks 404, and then start the servo motor 302 counterclockwise, the servo motor 302 runs and drives the left rotating rod 304 to rotate, the left rotating rod 304 drives the left belt pulley 306 to rotate, and the left belt pulley 306 drives the right belt pulley 306 to rotate through the belt, so that the two rotating rods 304 rotate at the same time, and the rotating rod 304 drives the take-up roller 305 to rotate. Because the hanging rope 307 is wound on the surface of the take-up roller 305, and the hanging ropes 307 on both sides are wound on the take-up roller 305 in opposite directions, the two take-up rollers 305 will reel in the two hanging ropes 307 at the same time when they rotate counterclockwise, thereby driving the two fixing mechanisms 4 to rise at the same time, effectively improving the stability of the goods when they are lifted, and during the reeling process of the hanging rope 307 During the process, the hanging rope 307 will preferentially pull the installation box 401 up, and the rising of the installation box 401 will drive the second spring 402 and the support rod 410 to rise, and the support rod 410 will drive the L-shaped rod 408 to rise. During the rising process of the L-shaped rod 408, the top of the L-shaped rod 408 will push the third sliding block 407 to move backward along the second sliding block 406, and at the same time, the L-shaped rod 408 will rotate around the support rod 410, and the bottom of the L-shaped rod 408 will push the clamping ring 411 to move with the opening of the hook 404. When the installation plate 403 contacts the bottom of the installation box 401, the clamping ring 411 will contact the inner wall of the opening of the hook 404, thereby forming a closed space. When the hanging rope 307 continues to rise, the installation box 401 will block the installation plate 403.At this time, the goods will rise as the hook 404 is started. Due to the gravity of the goods, during the lifting process of the goods, the clamp ring 411 will always be in contact with the hook 404 to prevent the goods from being separated from the hook 404 due to shaking, resulting in the goods falling and being damaged. Then the moving motor 205 is started, and the moving motor 205 drives the threaded rod 206 to rotate. The rotation of the threaded rod 206 causes the second slider 207 to move along the threaded rod 206. The second slider 207 drives the adjustment mechanism 1 to move, the adjustment mechanism 1 drives the lifting mechanism 3 to move, and the lifting mechanism 3 drives the fixing mechanism 4 to move, so that the goods The mounting box 101 drives the fixing rod 208 to move, the fixing rod 208 drives the connecting rod 209 to move, and the connecting rod 209 drives the roller 210 to move along the guide wheel groove 204, thereby improving the stability of the adjustment mechanism 1 during movement.
