[0002] Hydrometallurgy is a kind of method for extracting, separating and purifying metal by using the chemical reaction of metal ions in solution. Hydrometallurgy has gradually become mainstream and has an important position in the metallurgical industry due to its advantages of environmental protection, high efficiency, low energy consumption and low cost. In the hydrometallurgy process, lead alloy anode plate is one of the core production components, and the lead alloy anode plate used by the smelting plant is obtained by melting lead alloy, then casting lead alloy anode slab, then slab rolling, and finally cutting and machining the lead alloy anode plate according to the structure of the electrolytic cell of the smelting plant.

[0020] As Figs. 1-2 shown in the prior art in the present embodiment, the following problems exist: in the production process, the inventor finds that after casting, the lead alloy slab is then transferred and transported to the slab rolling process, because the alloy slab is heavy, the residual temperature is high, manual handling efficiency is low, and safety risk is high, so the conventional lifting chain is used for lifting and transporting by the travelling crane. However, in the process of using the lifting chain for handling, because the slab itself is too heavy, the lifting chain will be damaged and the slab will be damaged, and at the same time, in order to stably lift the slab, multiple lifting chains need to be wound on the slab, which will reduce the handling efficiency.

[0021] Therefore, the inventor provides a lead alloy slab lifting device, which comprises a clamping arm, a lifting chain 3 and a bag belt 4, the clamping arm further comprises a first clamping arm 1, a second clamping arm 2 and a pin 7 structure, the first clamping arm 1 and the second clamping arm 2 are cross-connected by the pin 7 structure located in the upper side of the two, and the working length of the clamping arm can be adjusted by changing the cross position of the first clamping arm 1 and the second clamping arm 2, the lifting chain 3 is connected at the top end of the first clamping arm 1 and the second clamping arm 2 through a hinge, and the bag belt 4 is divided into front and rear two parallelly installed lower side supports 8 of the clamping arm.

[0022] The effect is that: the device has a simple structure, when manually or by equipment handling, the clamping arm can clamp the slab by lifting the lifting chain 3, and because of the gravity of the slab, the anti-skid clamping pad 5 at the lower end of the clamping arm can generate friction with the slab, the heavier the slab, the greater the friction, and the more difficult the slab is to slip; at the same time, the device can protect the clamped slab under the action of the bag bottom of the bag belt, and the cross position of the first clamping arm 1 and the second clamping arm 2 can be adapted according to the amount of the lifted slab, so as to adjust the working length of the clamping arm; therefore, the device not only can improve the efficiency of manual or equipment handling, but also can increase stability and reduce safety hazards, and because the bag belt can be freely assembled and disassembled and the working length of the clamping arm can be adjusted, the bag belt can facilitate lifting and transporting other materials such as cutting edge materials, bulk materials and spare parts.

[0023] Further, the lower end of the first clamping arm 1 and the second clamping arm 2 is hingedly installed with an anti-skid clamping pad 5 with adjustable angle; the structure can conveniently adjust the clamping angle when the working length of the clamping arm is adjusted, so as to adapt to the above-mentioned situation.

[0024] Further, the pin 7 structure further comprises pin holes 6 and pins 7, the pin holes 6 are arranged on the middle upper side of the first clamping arm 1 and the second clamping arm 2, and a plurality of pin holes 6 are symmetrically arranged on each clamping arm, and the pins 7 are detachably arranged at the intersection of the first clamping arm 1 and the second clamping arm 2; the structure can conveniently adjust the working length of the clamping arm when hoisting different types of plates or hoisting other materials.

[0025] Further, the two ends of each pocket belt 4 are respectively connected to the lower side supports 8 of the first clamping arm 1 and the second clamping arm 2; the structure can more stably pocket the bottom of the plate and reduce safety hazards.

[0026] Further, the two ends of the pocket belt 4 are provided with locking buckles (not shown in the figure) for winding and unwinding the pocket belt 4; the structure can make the operation more flexible.

[0027] The working principle of the utility model is as follows: when in use, the plate to be carried is vertically placed, the clamping arm is placed above the plate, then the pocket belt 4 is placed at the bottom of the plate, and then the lifting chain 3 is lifted, the anti-skid clamp pads 5 on the first clamping arm 1 and the second clamping arm 2 clamp the plate, after lifting the plate, the pocket belt 4 is finally tightened through the locking buckle, so as to serve as double protection, and avoid the middle plate from sliding downward when the plate is lifted at the same time.
