Detailed Description
As shown in fig. 1 to 4, a lifting hook for a lead storage battery is used for lifting a plurality of heavier lead storage batteries, such as a tubular forklift battery, and the top surface of the lead storage battery is provided with a liquid injection hole. The lifting hook comprises a lifting ring 1, a round rod 2, a sleeve 3 and a lifting hook piece 4.
The lifting ring 1 is located at the top of the lifting hook, and the lifting ring 1 is used for being matched with lifting equipment for lifting. The lower part of the lifting ring 1 is provided with a connecting rod 11, and the connecting rod 11 and the lifting ring 1 are integrally formed. At least a bottom section of the connecting rod 11 is a threaded section 12, and the whole connecting rod 11 can also be provided with external threads.
The top of the round rod 2 is fixedly assembled with the connecting rod 11, and a threaded hole 21 in threaded fit with the threaded section 12 is formed in the top surface of the round rod 2. Through screw thread cooperation, make things convenient for dismouting to use. The middle part of the round bar 2 has a reduced diameter section 22 with a reduced outer diameter, and the middle part is not necessarily the right center, and any middle area can be used. Since the top of the round bar 2 needs to be provided with a threaded hole, the area of the round bar 2 located at the lower part of the reduced diameter section 22 does not need to be long, and the area located at the lower part of the reduced diameter section 22 needs to extend into the liquid injection hole of the lead storage battery when the round bar is used, the area is not too long, so that the reduced diameter section 22 is generally located at the lower part of the round bar 2.
The outer diameter between the diameter-reduced section 22 and the bottom of the round rod 2 is gradually enlarged to form a locking surface 23, and the outer diameter between the diameter-reduced section 22 and the top of the round rod 2 is gradually enlarged to form an unlocking surface 24.
The sleeve 3 is sleeved on the periphery of the round rod 2. The sleeve 3 has a grip 31 at the upper part and a hinge 32 at the lower part.
The hook members 4 comprise a plurality of reduced diameter sections 22 arranged around the round bar 2, preferably the number of hook members 4 is 3 to 6, more preferably 4, and preferably each hook member 4 is of the same size and is evenly arranged around the reduced diameter sections 22 of the round bar 2 so that the load on lifting is relatively even.
Each hook member 4 includes a stem portion 41 arranged in the axial direction of the round bar 2 and a hook portion 42 at the bottom end of the stem portion, protruding outward, and the middle portion of each hook member 4 is hinged to the sleeve 3, and each hook member 4 has a locked state in which the locking surface 23 presses the bottom inner side of the hook member 4 to rotate the hook member 4 along the hinged axis when the round bar 2 is lifted, and the bottom inner side of the hook member 4 is pulled out from the locking surface 23 to reset the hook member 4 when the hook member 4 is displaced upward relative to the round bar 2.
The middle part of each hook member 4 in the present application is hinged to the sleeve 3, and the middle part is not necessarily the exact center position, so long as the hook member 4 can be normally switched between the locked state and the unlocked state in a certain region in the middle. The hinge portion 32 of the sleeve 3 is divided into a plurality of regions extending downwardly from the handle portion 31 with spaces between adjacent regions into which the tops of the hook members 4 extend. A hinge shaft 5 is provided between each two regions of the hinge portion 32, and a hook member 4 is correspondingly mounted. Pin shafts 6 are driven into corresponding positions on the outer peripheral surface of the hinge part 32 to fix the hinge shaft 5.
The inner side of the bottom of the hook member 4 has a first guide surface 43 which facilitates engagement with the locking surface 23. The top inner side of the hook member 4 has a second guide surface 44 which facilitates engagement with the release surface 24.
When the lifting hook is used, the lifting hook parts 42 of the lifting hook parts 4 extend into the liquid injection holes of the lead storage batteries when the lifting hook parts 4 are in the unlocking state, the lifting device lifts the lifting hook according to the application, the lifting ring 1 is lifted along with the round rod 2 when lifted, the locking surface 23 on the round rod 2 presses the first guide surface 43 on the inner side of the bottom of the lifting hook parts 4, the lifting hook parts 4 rotate around the hinge shaft 5, the lifting hook parts 42 of the lifting hook parts 4 tilt outwards to enter the locking state, and the battery cover of the lead storage batteries is supported by the outwards tilted lifting hook parts 42 to be positioned on the inner bottom surface around the liquid injection holes, so that the lead storage batteries can be lifted. After the lead storage battery is hoisted to the destination position, the handheld part 31 of the sleeve 3 is held and pushed upwards, so that the sleeve 3 moves upwards together with the lifting hook piece 4, the unlocking surface 24 on the round rod 2 presses the second guiding surface 44 on the inner side of the top of the lifting hook piece 4, the lifting hook piece 4 is reset to the unlocking state, and the lifting hook is taken out from the liquid injection hole of the lead storage battery to hoist the next lead storage battery.
