Description
Technical Field
[0001] The present application relates to the technical field of lifting equipment, and in particular to a duckbill lifting device for pre-embedded double-head lifting ring staggered bolts. Background Art
[0002] With the continuous development of construction and engineering technology, the demand for lifting and moving large and heavy equipment or structural parts is increasing. In these lifting operations, the lifting equipment plays a vital role. The lifting equipment needs to bear huge weights while ensuring stability and safety during the lifting process.
[0003] At present, general lifting tools usually tie objects together and knot them first, then hook the objects with hooks, and pull the hooks with cranes to move the objects.
[0004] However, during the movement, the objects are prone to shaking and falling off the hook, causing the objects to break and cause losses, thereby reducing the stability of transportation. Utility Model Content
[0005] In order to improve transportation stability, the present application provides a duckbill sling for pre-embedded double-head lifting ring staggered bolts.
[0006] The present application provides a duckbill sling for pre-buried double-head lifting ring staggered bolts, which adopts the following technical solution:
[0007] A duckbill sling for a pre-buried double-headed lifting ring and staggered bolt, comprising a lifting ring, a duckbill clamp, a double-headed staggered bolt, a fixing assembly and a reinforcing assembly, wherein the duckbill clamp is arranged on the lifting ring; a semi-annular groove is provided on the duckbill clamp, and both ends of the double-headed staggered bolt are fixedly connected with sliders; the slider is slidably connected in the semi-annular groove; the fixing assembly is arranged on the semi-annular groove and is used to limit the position of the double-headed staggered bolt; the reinforcing assembly is arranged on the duckbill clamp and is used to increase the connection strength between the duckbill clamp and the lifting ring.
[0008] By adopting the above technical solution, one end of the double-headed staggered bolt is installed on the cargo, and the other end is installed on the duckbill clamp. The fixing assembly limits the position of the double-headed staggered bolt to prevent sliding or falling off during use, thereby enhancing the safety and reliability of the spreader.
[0009] In addition, the reinforcement component increases the connection strength between the duckbill clamp and the lifting ring, which not only improves the load-bearing capacity of the spreader, but also extends its service life, thereby reducing equipment damage and maintenance costs caused by loose or broken connections;
[0010] By pulling the lifting ring with a crane, the goods are easy to lift, thereby improving the transportation stability of the goods during the lifting process.
[0011] Optionally, fixing plates are fixedly connected on both sides of the notch of the semi-annular groove in a direction approaching each other.
[0012] By adopting the above technical solution, the slider of the double-headed staggered bolt can be supported on both sides when sliding, which reduces the shaking of the slider during the sliding process, thereby improving the stability of the double-headed staggered bolt in the semi-annular groove;
[0013] At the same time, the fixed plate can serve as a sliding boundary for the slider, limiting the slider from sliding out of the semi-annular groove, further enhancing the connection reliability between the double-headed staggered bolt and the duckbill clamp.
[0014] Optionally, one end of the semi-annular groove is flared.
[0015] By adopting the above technical solution, since one end of the notch is enlarged, the slider can slide into the semi-annular groove more easily from the larger opening, thereby reducing the difficulty during installation.
[0016] Optionally, the fixing assembly is provided with two groups, and the two groups of fixing assemblies are arranged along the length direction of the semi-annular groove; one of the fixing plates is provided with two slide grooves, and the two slide grooves are arranged along the length direction of the semi-annular groove; the other fixing plate is provided with two connecting holes, and the two connecting holes correspond to the two slide grooves one by one, and are arranged opposite to the two slide grooves; the fixing assembly includes a screw and a nut, the screw is passed through the connecting hole, and one end is threadedly connected to the slide groove; the nut is threadedly connected to the end of the screw away from the slide groove.
[0017] By adopting the above technical solution, when the position of the double-headed staggered bolt is adjusted, the screw is rotated to make one end of the screw threadedly connected to the slide groove, and then the nut is threadedly connected to the other end of the screw, so that the double-headed staggered bolt is firmly fixed in the semi-annular groove, thereby enhancing the stability of the sling structure.
[0018] Optionally, the reinforcement assembly includes a reinforcement plate, a bolt and two nuts, the reinforcement plate is fixedly connected to the duckbill clamp and is located on one side of the lifting ring; through holes are provided on the reinforcement plate and the lifting ring; the bolt is inserted into the through hole, and the two nuts are threadedly connected to the end of the bolt away from the head.
[0019] By adopting the above technical solution, after the position of the double-headed staggered bolt is fixed, the reinforcement plate is tightly connected to the duckbill clamp and the lifting ring through bolts and nuts. When the sling is under load, the reinforcement plate can disperse the stress to a larger area and reduce stress concentration, which helps to extend the service life of the sling, thereby easily reducing damage and failure caused by stress concentration.
[0020] Optionally, a side of the sliding block close to the fixed plate is rotatably connected to a plurality of balls, and the plurality of balls are arranged around an axis of the double-headed staggered bolt.
[0021] By adopting the above technical solution and setting the ball bearings, the friction between the slider and the fixed plate can be significantly reduced. When the slider slides, the ball bearings roll, thereby reducing the friction resistance, so that the double-headed staggered bolt can move more smoothly in the semi-annular groove.
[0022] Optionally, a reinforcing plate is passed through the screw rod, and the reinforcing plate is fixedly connected to the fixing plate; the nut is located on a side of the reinforcing plate away from the connecting hole.
[0023] By adopting the above technical solution, the reinforcing plate is connected to the fixing plate through screws to form a more stable structure. This connection enhances the connection strength between the fixing plate and the screws and improves the rigidity of the entire structure, thereby making the sling more stable when bearing loads.
[0024] Optionally, gaskets are provided between the bolt head, the nut 2 and the lifting ring.
[0025] By adopting the above technical solution, since the gasket has a certain friction coefficient, the friction between the bolt head and nut 2 and the eye can be increased, which helps to ensure that the bolt and nut 2 are not easy to loosen when subjected to vibration or external force, thereby easily improving the stability of the entire connection structure.
[0026] In summary, the present application includes at least one of the following beneficial technical effects:
[0027] 1. By setting a screw and a nut, the double-headed staggered bolt is firmly fixed in the semi-ring groove, thereby enhancing the stability of the hanger structure;
[0028] 2. By setting up reinforcement plates, bolts and nuts, it helps to extend the service life of the spreader, thereby facilitating the reduction of damage and failure caused by stress concentration;
[0029] 3. By setting the ball bearings, the friction resistance of the slider is reduced, so that the double-headed staggered bolt can move more smoothly in the semi-annular groove. BRIEF DESCRIPTION OF THE DRAWINGS
