Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.
A kind of mechanical hoisting clamping device as shown in FIG. 1 to FIG. 3, including crossbeam 1, stringer 2, clamping limb 3, suspension hook 4, The stringer 2 is fixedly connected on the both ends of crossbeam 1, and rotation axis 21 is arranged in the stringer 2, and the rotation axis 21 includes first turn Axis 22 and the second shaft 23, the first rotating shaft 22 and the second shaft 23 are rotatablely connected, and the clamping limb 3 is set to stringer 2 Two sides of the bottom, the clamping limb 3 are fixed by connecting rod 31 with first rotating shaft 22, the second shaft 23 respectively, clamping limb 3 described in two sides Bottom fix the first claw 32 and the second claw 33 respectively, card slot 34, the card slot 34 is arranged in 32 front end of the first claw Engage with the second claw 33, the suspension hook 4 is set to the bottom of stringer 2, connects loop bar 41, the loop bar at the top of the suspension hook 4 Telescopic rod 42 is arranged in 41 upper ends, and the telescopic rod 42 is fixed on the bottom of stringer 2, and the is connected between the loop bar 41 and stringer 2 One spring 43, the hinged pull rod 44 in 41 outside of loop bar, the other end and clamping limb 3 of the pull rod 44 are hinged, the rotation axis 21 one end, which are pierced by outside stringer 2, connects ratchet 5, ratchet 5 is corresponded on the outside of the stringer 2, pawl 51, the pawl 51 and ratchet 5 is arranged Engaging.
Furthermore, 1 bottom of crossbeam is evenly equipped with bandage 11, and bandage 11 is used to tighten the outside of reinforcing bar, further Improve safety when lifting.
Furthermore, hanging ring 12 is provided at the top of the crossbeam 1, hanging ring 12 for connecting with hoisting mechanism, hang by realization Fill work.
Furthermore, 2 bottom both ends respective link 31 of the stringer setting opening 24, the opening 24 and connecting rod 31 are sliding Dynamic cooperation.
Furthermore, by 35 connecting cleat 36 of second spring on the inside of the clamping limb 3, clamping plate 36 can clamp reinforcing bar Group reduces shaking when lifting.
Furthermore, the clamping plate 36 is set as arc panel.
Furthermore, rubber pad 37 is set on the inside of the clamping plate 36, avoids clamping plate 36 from directly contacting with reinforcing bar, causes to grind Damage damage, reduces its service life.
Working principle: in use, the clamping device is passed through the hanging ring 11 of 1 upper end of crossbeam and the wire sling of boom hoisting It is connected and fixed, reinforcing bar group etc. can be lifted.
Firstly, crossbeam 1 is lowered into reinforcing bar group upper end by wirerope, the first claw 32 and the second card under idle state Pawl 33 is open configuration, thus, the two sides of reinforcing bar group end can be wrapped in.At this point, by suspension hook 4 with trigger tying up for reinforcing bar group Then rope controls the contraction of boom hoisting wirerope, is lifted by crane.
When wirerope is shunk, crossbeam 1 gradually pulls the reinforcing bar group of lifting with its rising.At this point, suspension hook 4 is with crossbeam 1 Rise, and the gradually gravity traction by its lower end bar group, drives 41 slide downward of loop bar, loop bar 41 can then pass through pull rod The clamping limb 3 of 44 pulling two sides, which synchronizes, to turn to the inside, so that the second claw 33 of 3 inside of clamping limb is gradually caught in the first card In card slot 34 on pawl 32, thus the reinforcing bar group end clamping that suspension hook 4 is sling.The clamping limb 3 of two sides is by connecting rod 31 and turns Moving axis 21 connects, and rotation axis 21 is made of first rotating shaft 22 and the second shaft 23, and the two is rotatablely connected by connector sleeve, rotation Junction is equipped with ball bearing, guarantees the stability of its rotation and the intensity of connection, avoids being broken.
In addition, 3 inside of clamping limb is also by 35 connecting cleat 36 of second spring, clamping plate 36 is under the action of second spring 35 Further the end of reinforcing bar group is fixedly clamped, avoids shaking when lifting.
When lifting, if the fracture of suspension hook 4, at this time under the clamping of two sides the first claw 32 and the second claw 33, steel occurs Muscle group is not fallen out, also, under the bundled fixed of bandage 11, substantially increases safety when lifting.
It is to put down crossbeam 1 when reinforcing bar group is lifted to using position, then unclamps bandage 11, and release the hook of suspension hook 4 It hangs, meanwhile, it pushes pawl 51 aside, at this point, loop bar 41 resets rapidly under the action of the first spring 43, and is driven by pull rod 44 First claw 32 of two sides and the second claw 33 open, so as to by the taking-up of reinforcing bar group carry out using.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this Novel conception and scope is defined.Without departing from the design concept of the present utility model, ordinary people in the field couple The all variations and modifications that the technical solution of the utility model is made, should fall within the protection scope of the present utility model, this reality With novel claimed technology contents, it is all described in the claims.
