Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of auxiliary equipment for steel mills, and particularly relates to a billet clamp that can improve the operation accuracy of the clamp. Background Technique
[0002] The billet clamp uses the lever principle to lift the billet, does not require a power source, and realizes positioning and locking by a rotary opener or a mechanical opener. It can lift single-layer and multi-layer billets, and has the characteristics of flexible operation, safety and reliability. The billet clamp mainly consists of a suspension beam, a clamp and an opening and closing mechanism. The billet clamp is connected to the crane hook through the top of the suspension beam. Generally, there are two clamps, and the two clamps are respectively arranged at both ends of the suspension beam and connected by hinges. The opening and closing mechanism is fixed in the middle of the bottom of the suspension beam.
[0003] At present, an automatic opening and closing mechanism is commonly used. The automatic opening and closing mechanism is a mechanism that controls the automatic opening and closing of the billet clamp. The automatic opening and closing mechanism includes an opening and closing drive, a rotatable block and a lifting plate provided with a card slot. It is necessary to set a cross beam at the bottom end of the clamp, and a lifting plate is set on the cross beam. The suspension beam presses down to extend the block into the card slot, and then the opening and closing drive drives the block to rotate 90°, so that the block is stuck in the card slot, and then the suspension beam lifts the cross beam to lift the empty clamp.
[0004] However, when the suspension beam falls back, it is necessary for the operator to visually align and fall back in order to make the block fall into the card slot. The operation is difficult and it is difficult to adapt to high-efficiency production use. Moreover, although the hinge has a certain limiting effect on the block entering the card slot, with frequent use, the parts between the hinges will wear, increasing the overall play of the clamp, which will exacerbate the situation of the block falling back incorrectly. The block and the card slot cannot be accurately aligned, resulting in damage to the edge of the card slot, and the block cannot be accurately stuck in the card slot, resulting in the billet clamp not being able to be used normally. There are great potential safety hazards in operation. Summary of the Invention
[0005] The utility model provides a billet clamp that can improve the operation accuracy of the clamp, which can reduce the limitation of the overall play of the clamp on the normal use of the clamp. It is convenient for the block to accurately enter the card slot and improves work efficiency.

Detailed implementation manners
[0018] The following further describes in detail the detailed implementation manners of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model.
[0019] As Figures 1 to 4 shown, the present utility model includes an opener, a clamp 1, a suspension beam 2 and a cross beam 3. Both ends of the suspension beam 2 are hinged to the clamp 1. Both ends of the cross beam 3 are connected to the side surface of the clamp 1. The drive mechanism 44 of the opener is fixed below the suspension beam 2. The clamping groove 5 of the opener is arranged on the cross beam 3. It is characterized in that a longitudinal guiding mechanism is further provided, and the longitudinal guiding mechanism is arranged between the suspension beam 2 and the cross beam 3. The longitudinal guiding mechanism can guide the clamping block of the opener to enter the clamping groove 5 from left and right sides, and can guide left and right during the process that the drive mechanism 44 of the opener pushes the clamping block into the clamping groove 5.
[0020] The opener is fixed at the middle position of the suspension beam 2. The longitudinal guiding mechanism is arranged on the left side of the opener. The longitudinal guiding mechanism includes a longitudinal guide post 6, a longitudinal base 7 and a longitudinal guide hole 8. The longitudinal base 7 is fixed on the cross beam 3. The longitudinal guide hole 8 is arranged on the longitudinal base. The longitudinal guide post 6 is fixed on the bottom surface of the suspension beam 2. Longitudinal guide blocks 14 are respectively arranged on the left and right sides of the longitudinal guide hole 8, and slopes are arranged on the inner sides of the longitudinal guide blocks 14. After the clamp 1 releases the material, the suspension beam 2 descends, and the longitudinal guide post 6 falls between the longitudinal guide blocks 14. The longitudinal guide post 6 slides down along the inclined surface into the longitudinal guide hole 8. At this time, it can help to guide the left and right positions of the clamping block during its descent.
[0021] Meanwhile, to ensure the accurate front and rear positions of the descending clamping block, a lateral guiding mechanism is further provided. The lateral guiding mechanism is arranged on the right side of the opener. The lateral guiding mechanism includes a lateral guiding column 9, a lateral base 10, and a lateral guiding hole 11. The lateral base 10 is fixed on the cross beam 3. The lateral guiding hole 11 is arranged on the lateral base. The lateral guiding column 9 is fixed on the bottom surface of the hanging beam 2. Lateral guiding blocks 15 are respectively arranged on the front and rear sides of the lateral guiding hole 11. Slopes are arranged on the opposite surfaces of the two lateral guiding blocks 15. While the longitudinal guiding column 6 slides down along the inclined surface into the longitudinal guiding hole 8, the lateral guiding column 9 falls between the lateral guiding blocks 15 and falls into the lateral guiding hole 11 along the slope. Finally, the clamping block falls into the clamping groove and rotates to lift the clamp.
[0022] To avoid the sliding friction between the longitudinal guiding column 6 and the longitudinal guiding block 14, the longitudinal guiding hole 8 is a square hole. A longitudinal guiding roller 12 is arranged at the bottom of the longitudinal guiding hole 8. The axis of the longitudinal guiding roller 12 is perpendicular to the cross beam 3. The parameters of the longitudinal guiding roller 12 match those of the longitudinal guiding hole 8 so that the longitudinal guiding roller 12 can stably fall into the longitudinal guiding hole 8. Changing the dynamic friction to rolling friction also improves the guiding accuracy.
[0023] Similarly, to avoid the sliding friction between the longitudinal guiding column 6 and the longitudinal guiding block 14 and improve the guiding accuracy. The lateral guiding hole 11 is a square hole. A lateral guiding roller 13 is arranged at the bottom of the lateral guiding hole 11. The axis of the lateral guiding roller 13 is parallel to the cross beam 3. The parameters of the lateral guiding roller 13 match those of the lateral guiding hole 11.
[0024] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
