Description

Technical Field

[0001] The utility model relates to the technical field of balancers, in particular to an automatic control balancer. Background Art

[0002] Spring balancers are widely used in various production lines. They mainly use the energy stored in the internal coil spring to offset the tension of the wire rope and the gravity of the object suspended on the balancer, so that the object is in a weightless state and can move freely up and down. It has been observed that the following problems still exist when using the balancer:

[0003] 1. The existing balancer's wire rope is wound around the side of its internal pulley. When in use, the wire rope is generally placed inside the guide groove on the side of the shell. However, as the 5 unwinds and slides inside the guide groove, the 5 itself will produce positional deviation and swing, causing the wire rope to fall out of the groove and get stuck, affecting subsequent use;

[0004] 2. Although the existing balancer can make the object in a weightless state through the energy accumulated by the internal coil spring, if the coil spring or internal parts are damaged, the tool will fall and be damaged, and may cause harm to personnel. Therefore, an automatic control balancer is proposed. Utility Model Content

[0026] like Figures 1 to 2As shown, the automatic control balancer includes a shell 1, which is a conical body with a hollow interior. A guide groove 11 is provided on the side of the shell 1, and the guide groove 11 is a rectangular groove. A slot 12 that passes through the shell 1 is provided on the inner wall of the guide groove 11, and the slot 12 is a rectangular groove. A step pulley 4 is movably installed inside the shell 1 and the step pulley 4 is rotatably connected to the inner position of the shell 1 through a circular shaft. The step pulley 4 is a threaded frustum block with a groove on the side. An upper hook 3 is rotatably installed on the upper side of the shell 1. An adjusting torsion spring assembly 2 is provided on the side of the shell 1. The torsion spring assembly 2 is composed of a torsion spring, a card and a rectangular rod. By adjusting the torsion spring assembly 2, the torsion spring torsion is adjusted to exert elastic force on the step pulley 4. A steel wire rope 5 is fixedly installed on the side of the step pulley 4 and the steel wire rope 5 is threadedly arranged in its groove and extends to the internal position of the guide extension groove 11. A lower hook 6 is fixedly installed on the lower side of the steel wire rope 5 and a rubber buffer block is provided on the upper side of the lower hook 6. A guide rope assembly 7 that can guide the steel wire rope 5 is provided inside the slot 12, and an anti-fall assembly 8 that can brake the steel wire rope 5 is provided on the side of the guide rope assembly 7.

[0027] Specifically, the upper hook 3 hangs and fixes the shell 1, and the elastic force on the tower wheel 4 is adjusted by adjusting the torsion spring assembly 2. The lower hook 6 hangs the tool and pulls it to balance and suspend it for use. The guide rope assembly 7 provided can guide and constrain the wire rope 5 when it is reeled in and out, ensuring that the wire rope 5 is guided and continuously enters the side groove of the tower wheel 4 to avoid it from falling out of the groove. The anti-fall assembly 8 provided can generate a braking operation when the wire rope 5 falls rapidly to prevent the tool from falling.

[0028] like Figures 1 to 3 As shown, the guide rope assembly 7 includes a guide block 71 movably mounted inside the guide extension groove 11 and the guide block 71 is movably sleeved on the side of the wire rope 5. The guide block 71 is a rectangular block with a circular groove on the side. Elastic blocks 72 are symmetrically fixedly mounted on the side of the guide block 71. The elastic block 72 is a "C"-shaped block made of spring steel. A slider 73 is fixedly mounted on the side of the elastic block 72 and the slider 73 fits the inner wall position of the guide extension groove 11. The slider 73 is a rectangular block made of wear-resistant plastic. A connecting block 74 is fixedly mounted on the side of the guide block 71 and the connecting block 74 is movably mounted in the inner position of the slot 12. The connecting block 74 is a rectangular block. When the connecting block 74 is away from the guide A constraint groove 75 is provided on the side of the block 71. The constraint groove 75 is a cylindrical groove with a convex cross-section. A constraint rod 76 is movably installed inside the constraint groove 75 and the constraint rod 76 extends out of the inner position of the constraint groove 75. The constraint rod 76 is a circular rod with a "T"-shaped cross-section. A constraint block 77 is fixedly installed on the side of the constraint rod 76 and the constraint block 77 fits on the side of the shell 1. The constraint block 77 is a four-fifths spherical block. A connecting tube 78 is fixedly connected between the side of the constraint rod 76 and the inner wall of the constraint groove 75 and the connecting tube 78 is movably sleeved on the side of the constraint rod 76. The connecting tube 78 is a spring steel cylinder with a continuous "W"-shaped cross-section;

[0029] Specifically, the guide block 71 is provided to constrain the wire rope 5 when it contracts, and when the wire rope 5 is unwound on the side of the tower pulley 4, the guide block 71 slides inside the guide groove 11, and the slider 73 fits against the inner wall of the guide groove 11 to squeeze the elastic block 72 to deform so that the guide block 71 slides against the wall, ensuring that the wire rope 5 does not swing inside the guide groove 11, and the synchronous connecting block 74 slides inside the slot 12 to further constrain the guide block 71, and the constraint block 77 fits against the side of the shell 1, and the connecting tube 78 is provided to elastically constrain the connecting block 74, further ensuring the stable constraint of the wire rope 5 by the guide block 71.

[0030] like Figure 3 and Figure 4 As shown, the anti-fall component 8 includes a matching shaft 81 symmetrically arranged on the upper side of the guide block 71 and the matching shaft 81 is fitted to the side position of the wire rope 5. The matching shaft 81 is a round shaft made of wear-resistant rubber. Fixed seats 82 are movably sleeved on both sides of the matching shaft 81 and the fixed seats 82 are fixedly installed on the upper side of the guide block 71. The fixed seat 82 is a rectangular block with a circular groove on the side. The matching shaft 81 can be constrained by the fixed seat 82 for rotation. A card wheel 83 is fixedly installed on the side of the fixed seat 82. The card wheel 83 is a circular ratchet gear. A fixed shaft 84 is fixedly installed on the upper side of the guide block 71 at the position corresponding to the card wheel 83. The fixed shaft 84 is "C" shaped. A circular shaft is movably sleeved with a clamping block 85 on the side of the fixed shaft 84. The clamping block 85 is an "L"-shaped block with an inclined surface on one side. When the clamping block 85 is not triggered, it fits on the upper side of the guide block 71 under its own gravity. A mounting groove 86 is provided on the side of the mating shaft 81 corresponding to the clamping block 85. The mounting groove 86 is a fan-shaped groove. A trigger block 87 is movably installed inside the mounting groove 86 and the trigger block 87 is rotatably installed on the inner wall of the mounting groove 86 through a circular shaft. The trigger block 87 is an "L"-shaped block with an inclined surface on one side. An elastic rope 88 is fixed and squeezed between the side of the trigger block 87 and the inner wall of the mounting groove 86. The elastic rope 88 is a round rope made of rubber.

[0031] Specifically, the mating shaft 81 is arranged to fit on the side of the wire rope 5. When the wire rope 5 contracts, the mating shaft 81 can be driven to rotate. When a fall occurs, the wire rope 5 drops rapidly, and the mating shaft 81 is driven to rotate rapidly. At this time, the trigger block 87 rotates under the centrifugal force, and it pulls the elastic rope 88 to deform and slide out of the installation groove 86. The trigger block 87 is squeezed on the side position of the clamping block 85 to rotate and clamp it on the side position of the clamping wheel 83. The clamping wheel 83 brakes the mating shaft 81, and the mating shaft 81 brakes the wire rope 5.

[0032] When the wire rope 5 is unwound, the locking block 85 inside the anti-falling assembly 8 is triggered by the trigger block 87 that swings out and is connected to the side of the card wheel 83, braking the locking shaft 81 to brake the wire rope 5, thereby preventing the tool hanging on the side of the lower hook 6 from falling and causing damage to the tool and personnel and causing injury.
