[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0026] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] Before lifting, the hydraulic telescopic sleeve 10 can drive the extrusion rod 8 to rise, so that the shear arm 4 can be squeezed. The shear arm 4 rotates and the torsion spring 6 is rotated. At the same time, the extrusion plates 12 at the bottom are separated from each other, and the anode is set between the two extrusion plates 12. The hydraulic telescopic sleeve 10 is reset, and the extrusion plates 12 are close to each other under the action of the torsion spring 6 to squeeze and fix the anode, thereby preventing the anode from falling off.

[0028] In the related art, the clamping and adjusting devices all use external force to drive the clamping device to fix the anode. When the external force disappears, the clamping device fails and there is a risk of the anode falling off.

[0029] In order to solve the problems in the related art to a certain extent, an embodiment of the present application provides a multifunctional overhead crane anode anti-falling device. When it is needed, it only needs to move the extrusion rod 8 upward to drive the shear arm 4 to swing so that the extrusion plates 12 move away from each other and fix the anode through the extrusion plate 12, and it can always remain clamped under the action of the torsion spring 6.

[0030] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0031] Combination Figure 1-Figure 4 The embodiment of the present application provides a multifunctional overhead crane anode anti-falling device, including a base plate 1, support frames 2 are fixedly installed on both sides of the upper surface of the base plate 1, the two support frames 2 are fixedly connected by a hinge shaft 3, the outer surface of the hinge shaft 3 is symmetrically rotatably connected to two scissor arms 4, the hinge shaft 3 is located on the outer side of the scissor arm 4 and is sleeved with a connecting block 5, the connecting block 5 and the base plate 1 are fixedly connected, the connecting block 5 and the scissor arm 4 are fixedly connected by a torsion spring 6, a protrusion 7 is fixedly installed on the side where the scissor arms 4 are close to each other, an extrusion rod 8 is arranged below the protrusion 7, a lifting frame 9 is arranged on the outer side of the hinge shaft 3 on the upper surface of the base plate 1, a hydraulic telescopic sleeve 10 is fixedly installed above the lifting frame 9, the hydraulic telescopic sleeve 10 is fixedly connected to the extrusion rod 8, a limit rod 11 is fixedly installed above the lifting frame 9, the limit rod 11 passes through the extrusion rod 8, and an extrusion plate 12 is fixedly installed at the bottom end of the scissor arm 4.

[0032] Specifically, there are multiple groups of scissor arms 4, and the multiple groups of scissor arms 4 are equidistantly distributed. The scissor arms on the same side are fixedly connected by an extrusion plate 12. Such an arrangement can ensure that the extrusion plate 12 is subjected to uniform force.

[0033] In some embodiments, an electromagnetic block 13 is fixedly installed on one side of the extrusion plate 12 away from each other. The symmetrical electromagnetic blocks 13 attract each other after being energized. Such a setting can help fix the extrusion plate 12 and play a protective role after the torsion spring 6 fails.

[0034] In some embodiments, a hanging frame 14 is fixedly mounted on the upper surface of the bottom plate 1, and the hanging end of the hanging frame 14 is located above the scissor arm 4. This arrangement can facilitate the hanging of the device.

[0035] Specifically, the sides of the extrusion plates 12 that are close to each other are tilted, and when the anode is clamped, the two surfaces of the extrusion plates 12 that are close to each other are parallel to each other. This arrangement can ensure that the contact area with the anode is increased during the hoisting and extrusion process.

[0036] The two ends of the extrusion rod 8 are rounded, and the cross-sectional shape of the projection 7 is an inverted right-angle trapezoid. Such an arrangement can ensure that the extrusion rod 8 can move upward to extrude the shear arm 4 to deflect.
