Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

As shown in fig. 1 and 2:

the embodiment of the utility model provides a hoist and mount balance adjustment ware, including U type pull rod 1 and lock body 2. The lock body 2 comprises a first lock body 3 and a second lock body 4, one end of the first lock body 3 is rotatably connected with one end of the second lock body 4, and the first lock body 3 and the second lock body 4 can be overlapped together around the rotating end; the concrete structure can be as follows: one end of the first lock body 3 and one end of the second lock body 4 are provided with a shaft lug 11, and the first lock body 3 and the second lock body 4 are rotatably connected together through a rotating shaft 12 penetrating through the shaft lug 11 and can be rotatably overlapped together around the rotating shaft 12.

The overlapped surfaces of the first lock body 3 and the second lock body 4 are provided with more than two pairs of first clamping grooves 5 and second clamping grooves 6 which are arranged in bilateral symmetry, and a first pull rod positioning groove 7 and a second pull rod positioning groove 8 which are respectively connected with the first clamping grooves 5 and the second clamping grooves 6 and extend to the end surfaces of the other ends of the first lock body 3 and the second lock body 4; a first clamping block 9 and a second clamping block 10 are respectively arranged at two ends of the U-shaped pull rod 1; wherein, the first locking groove 5 and the second locking groove 6 are obliquely arranged grooves, the first locking block 9 and the second locking block 10 are locking blocks with the same inclination direction as the first locking groove 5 and the second locking groove 6 (as shown in fig. 1, the first locking groove 5 and the second locking groove 6 of the first lock body 3 and the second lock body 4 are arranged in a V-shaped bilateral symmetry manner, correspondingly, the first locking block 9 and the second locking block 10 are arranged in a V-shaped bilateral symmetry manner along the central line of the U-shaped pull rod 1), and the first clamping groove 5, the second clamping groove 6, the first pull rod positioning groove 7 and the second pull rod positioning groove 8 on the first lock body 3 and the first lock body 3 are in an integrated structure, first draw-in groove 5, second draw-in groove 6, first pull rod constant head tank 7 and second pull rod constant head tank 8 on the second lock body 4 are integrated structure with second lock body 4, first fixture block 9 and second fixture block 10 are integrated structure with U type pull rod 1.

Hoist and mount balance adjustment ware is during the use, earlier with wire rope 13 cover in the circular arc end of U type pull rod 1, then arrange in the coincide respectively with U type pull rod 1 both ends in the coincide first lock body 3 and the second lock body 4 first pull rod constant head tank 7 and the second pull rod constant head tank 8 together, first fixture block 9 and second fixture block 10 block respectively in the coincide first lock body 3 together and the second lock body 4 one of them a pair of first draw-in groove 5 and second draw-in groove 6, turn to coincide first lock body 3 and second lock body 4 after that, at last with round pin hub connection lug and tool to lock. When in hoisting operation, the self-locking of the first lock body 3 and the second lock body 4 is realized by clinging to the groove walls of the first clamping groove 5 and the second clamping groove 6 close to one side of the U-shaped pull rod 1 under the action of pulling force. If the lock is unbalanced during the trial hoisting, the lock can be opened (the first lock body 3 and the second lock body 4 are opened), the extending length of the U-shaped pull rod 1 is adjusted, and the effect of adjusting the hoisting balance is achieved.

Therefore, through hoist and mount balance adjustment ware can extend and shorten (adjust the card in corresponding first draw-in groove 5 and second draw-in groove 6 with first fixture block 9 and the second fixture block 10 of U type pull rod 1) at great within range, adjust easy operation, easily, swiftly, improved the balanced operating efficiency of regulation hoist and mount, solve the problem that the traditional regulation hoist and mount balance method is inefficiency, this hoist and mount balance adjustment ware's simple structure moreover, the production and processing is easy, with low costs, be favorable to mass production, popularization and application.
