Description

Technical Field

[0001] The utility model relates to the field of zinc ingots, in particular to a zinc ingot grabbing device. Background Art

[0002] In the zinc smelting and processing industry, handling and stacking zinc ingots is a critical and frequent operation. Traditionally, zinc ingot handling devices have employed two opposing, right-angled L-shaped jaws to grip and move the ingots. While this design has met basic handling requirements to a certain extent, its limitations have become increasingly apparent as production scale has expanded and product quality requirements have increased.

[0003] Zinc ingots generally have a trapezoidal cross-section, narrow at the top and wide at the bottom. This unique shape often presents challenges when gripping them using right-angled L-shaped jaws. Because the jaw shape does not match the ingot's cross-section, the jaws must apply a significant clamping force to the ingot's tip to ensure a secure grip. This uneven distribution of force not only increases energy consumption but, more importantly, can easily damage the ingot's tip due to concentrated force, impacting the product's appearance and subsequent processing performance. Furthermore, damaged ingots can pose safety hazards during handling, such as slipping or breakage, posing a threat to production efficiency and personnel safety.

[0004] Therefore, developing a new type of gripping device that can better fit the cross-sectional shape of the zinc ingot, achieve uniform clamping and reduce damage to the zinc ingot has become a technical problem that needs to be urgently solved in the current industry. Utility Model Content

[0021] The present utility model will be further described in detail below in conjunction with the embodiments in the drawings.

[0022] As Figure 1-Figure 5 shown, a grasping device for zinc ingots includes a clamping pump 1 and two clamping arms 2. Both clamping arms 2 are L-shaped. On the inner side of the clamping arm 2, there are a guiding surface 3, a clamping surface 4, a tip accommodating groove 5, and a abutting surface 6 arranged in sequence from top to bottom. The guiding surface 3 is inclined. The two guiding surfaces 3 are oppositely arranged and in an open state. The trapezoidal zinc ingot enters the grasping device between the two guiding surfaces 3; the clamping surface 4 is inclined. The clamping surface 4 is used to directly contact the inclined side surface of the trapezoidal zinc ingot 20. The inclined surface can better fit the surface of the zinc ingot; the tip accommodating groove 5 is used to insert the tip of the trapezoidal zinc ingot into the tip accommodating groove 5 to prevent the tip of the zinc ingot from directly contacting the clamping arm 2, resulting in damage to the surface of the zinc ingot tip; the abutting surface 6 is used to contact the bottom surface of the trapezoidal zinc ingot 20 to help the two clamping arms 2 clamp the zinc ingot.

[0023] The clamping surface 4 includes a first clamping surface 7 and a second clamping surface 8. The first clamping surface 7 and the second clamping surface 8 have different inclination angles to achieve the clamping of at least two styles of trapezoidal zinc ingots 20 as shown in Figure 2 , Figure 3 shown. When the surface of the zinc ingot fits with the two clamping surfaces 4, it belongs to the best match of the zinc ingot. Even if they cannot fit completely, they can still be used normally. The inclination amplitude of the inclined side surface of the trapezoidal zinc ingot is the same as that of the guiding surface 3 to achieve the best clamping effect. The trapezoidal zinc ingot is inserted into the tip accommodating groove 5, and the inner wall of the tip accommodating groove 5 does not contact the tip of the trapezoidal zinc ingot to prevent damage to the tip of the zinc ingot. The angle between the first clamping surface 7 and the vertical line is A, and the angle between the second clamping surface 8 and the vertical line is B. Angle A < Angle B. In配合导向面3,使第一导向面3合第二导向面3的过度顺滑。如 Figure 4 shown, the clamping surface 4 includes a first clamping surface 7, a second clamping surface 8, and a third clamping surface 9. The first clamping surface 7, the second clamping surface 8, and the third clamping surface 9 have different inclination angles to achieve the clamping of at least three styles of trapezoidal zinc ingots. Above the clamping pump 1, there is a collision sensor assembly, which can immediately detect when the clamping pump 1 and the two clamping arms 2 collide, and immediately take measures such as sending an alarm or immediately stopping the movement.

[0024] As Figure 5As shown, the collision sensor assembly includes a first fixing plate 10 and a second fixing plate 11. A plurality of springs 12 are provided between the first fixing plate 10 and the second fixing plate 11. A sensing plate 14 is provided on the first fixing plate 10, and a sensor probe 13 is provided on the second fixing plate 11. When the clamping arm 2 collides, the positions of the sensing plate 14 and the sensor probe 13 change, causing the sensing value to change. A collision is detected when a change in the value occurs. The sensor probe 13 is a probe of a photoelectric sensor, and the sensing plate 14 is an alloy metal sheet. A groove 15 is provided on the second fixing plate 11. The probe is arranged around the groove, and the sensing plate 14 is inserted into the groove 15. This effectively utilizes the position of the fixing plates above and below the spring 12, and eliminates the need to provide additional space for the collision sensor assembly.
