Description

Technical Field

[0001] The utility model belongs to the technical field of lead-acid battery production equipment and relates to a self-gravity hanger. Background Art

[0002] With the mass production of lead-acid batteries, the power box team uses hook-suspended cranes to perform random inspections, grouping and transportation of a large number of single batteries. When lifting, the hook is inserted into the cylindrical injection hole of the battery cover and the battery cover is hooked to achieve the operation. Due to the size and structure limitations of the cylindrical injection hole of the battery cover, there is a risk of shaking and dropping the battery during the handling process. Secondly, the hook is suspended on one side of the battery, which is prone to eccentricity. During the lifting process, the battery is skewed, leaking battery acid and being hooked. In addition, when the hook is loading and unloading the battery, the gap between the hook and the cylindrical injection hole is very small, making it difficult for the operator to improve production efficiency. The existing invention patent number is CN101885449B. When lifting, a built-in steel pipe hoist can insert the jaw seats and jaws at the lower ends of the left inner hook plate and the right inner hook plate into the upright steel pipe, pull up the lifting ear, and the left connecting rod and the right connecting rod drive the left curved plate and the right curved plate to move, so as to pull the left inner hook plate. Under the action of the upper slider and the lower slider corresponding to the upper guide hole and the side guide hole, the left inner hook plate can only be translated to the left side. Similarly, the right inner hook plate will be translated to the right side. The jaws will open and be stuck on the inner wall of the steel pipe to be lifted. Continue to pull up the lifting ear to lift the steel pipe.

[0003] The prior art has the following technical defects:

[0004] In the above technical solution, the left and right hook plates are moved by pulling the lifting ears to clamp the steel pipe. In order to ensure the friction, no limit device is set. If the battery is directly hoisted, the hook plate may damage the battery's injection hole due to its own weight. In addition, the structure is complicated and is not applicable to this field. Utility Model Content

[0005] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art and provide a self-gravity hoisting device, which can realize stable transportation of batteries during lifting without damaging the batteries and can also improve the efficiency of hooking the batteries.

[0006] The self-gravity sling described in the utility model comprises a sling rope, a right sling rod and a left sling rod. The left sling rod is provided with a left-rotating sleeve, and the right sling rod is provided with a right-rotating sleeve corresponding to the left-rotating sleeve. The left-rotating sleeve and the right-rotating sleeve are hinged by a pin shaft. The bottoms of the left sling rod and the right sling rod are fixedly connected with hook feet, and the upper ends of the left sling rod and the right sling rod are fixedly connected with sling rings, and the two sling rings are both sleeved in the sling rope.

[0007] Working process or working principle:

[0008] When in use, hang the lifting rope on the crane hook, then pull down the lifting device by hand so that its two hook feet are close together and extend into the injection hole of the battery, then the crane hook lifts and pulls the lifting rope, the lifting rope drives the two lifting rings to rotate with the pin shaft as the fulcrum, thereby driving the hook feet to separate to both sides, and then get stuck in the injection hole and then be lifted and moved. When it is transported to the right place, lower the crane hook and manually merge the two hook feet to take out the injection hole to complete the lifting and transportation of the battery.

[0009] The left and right suspension rods are provided with corresponding left and right fixing plates, and a spring is provided between the left and right fixing plates. The spring can make the whole body Y-shaped when static, and the two hook feet are close together, so that the hook feet can be easily inserted into the cylindrical liquid injection hole of the battery cover for lifting.

[0010] An arc rod is fixedly connected to the left fixed plate, and the other end of the arc rod passes through the right fixed plate and the right suspension rod and is slidably connected thereto. The spring is sleeved on the arc rod. Since the movement trajectories of the left suspension rod and the right suspension rod are not linear motion, the spring will be deformed after working for many times. The use of the arc rod can prevent the spring from deforming and failing.

[0011] The left fixed plate is fixedly connected with an adjusting nut, and the adjusting nut is connected with a limiting bolt. The adjusting nut is welded on the left fixed plate, and the limiting bolt is screwed on the adjusting nut. The length of the limiting bolt can be adjusted by rotating the limiting bolt, and the supporting length of the limiting bolt and the right fixed plate can be adjusted to control the opening size of the hook leg to avoid excessive tension of the hook leg damaging the cylindrical liquid filling hole of the cylindrical battery when lifting overweight batteries.

[0012] The upper ends of the two hook feet are fixedly connected to corresponding hook legs, and the two hook legs are respectively fixedly connected to the left suspension rod and the right suspension rod. In order to be applicable to a variety of battery models, the hook feet can be designed to be compact. The gap between the hook feet and the cylindrical injection hole is large, which is conducive to improving work efficiency. At the same time, the hook legs are increased to strengthen the strength of the overall structure.

[0013] The outer side surface of the lower part of the hook leg is processed into an arc surface, and the hook foot is a semi-crescent-shaped small plate. The outer side surface of the hook foot at the lower part of the hook leg is processed into an arc surface. The arc surface can prevent the hook leg and the injection port from colliding and rubbing against each other during assembly, causing damage to the injection port. The hook plate at the bottom of the hook leg is a semi-crescent-shaped small plate, and the overall shape is butterfly-shaped when the hook feet are combined. Since the injection port is a circular hole, the semi-circular crescent-shaped small plate has a larger contact area than the rectangular plate and is more stable.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model is easy to operate and can realize stable lifting of batteries without falling off or damaging the batteries, and can also improve the efficiency of hooking batteries. BRIEF DESCRIPTION OF THE DRAWINGS

The spring 13 is sleeved on the arc rod 12. Since the motion trajectories of the left suspension rod 4 and the right suspension rod 10 are not linear motions, the spring 13 will be deformed after multiple operations. The arc rod 12 can be used to prevent the spring 13 from deforming and failing; the left fixed plate 8 is fixedly connected with an adjusting nut 16, and the adjusting nut 16 is connected with a limit bolt 5, and an adjusting nut 16 is welded on the left fixing plate 8, and the limit bolt 5 is screwed on the adjusting nut 16. The length of the limit bolt 5 is adjusted by rotating the limit bolt 5, and the supporting length of the limit bolt 5 and the right fixing plate 9 is adjusted to control the opening size of the hook foot 7 to avoid excessive tension of the hook leg 6 damaging the cylindrical liquid injection hole of the cylindrical battery when lifting overweight batteries; the upper ends of the two hook feet 7 are fixedly connected with a one-to-one corresponding hook leg 6, and the two hook legs 6 are fixedly connected to the left suspension rod 4 and the right suspension rod 10 respectively.
