The utility model discloses a beneficial effect is: the lifting device can lift and transport I-steel of various types without replacing the lifting device; greatly reducing the labor intensity of workers, reducing the occurrence of accidents such as I-shaped steel slide rails and the like, and eliminating potential safety hazards. And the structure is simple, the use is convenient, and the reliability is strong.
The utility model provides a I-steel hoist (CN108609483A) discloses an I-steel hoist, includes first lifting hook and second lifting hook, swing joint between first lifting hook and the second lifting hook, is provided with the bolt on the lateral wall of first lifting hook, and the inside of second lifting hook is provided with the slot with bolt matched with. Through set up the bolt on first lifting hook, set up the bolt on the second lifting hook, realize the swing joint between two lifting hooks to reach the centre gripping distance of adjusting between two lifting hooks, and then can be used for the I-steel of the different specifications of centre gripping.
Through the analysis, above-mentioned patent of disclosing with this application is all inequality in the aspect such as I-steel hoist and mount application of force position and safe release structure, consequently does not influence the novelty of this application.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's weak point, provide a I-steel is hoist and mount and is used combination hoist, this combination hoist cooperation hoist and mount are at the both ends of I-steel, make the hoist no longer receive the I-steel size influence, and effectively avoided the I-steel to its gliding problem of extending direction to set up safe stretching strap and effectively avoided the hoist pine to take off, improved hoist and mount factor of safety, and simple structure, low cost extensively is applicable to the hoist and mount construction of various model I-steels.
A combined lifting appliance for lifting I-steel comprises resistance hooks oppositely hung at two ends of the I-steel and a safety pull belt for connecting the two resistance hooks; the resistance hook comprises a bottom plate and a hook plate, wherein one end of the middle part of the bottom plate is provided with a slot inserted on the I-shaped steel vertical plate, and the other end of the middle part of the bottom plate is fixedly connected with the hook plate which is obliquely and upwards arranged; the middle part of the hook plate is provided with a safety hole which is horizontally communicated, and the top part of the hook plate is provided with a hoisting hole which is horizontally communicated.
And the two ends of the safety pull belt respectively penetrate through and are wound in the safety holes.
And rubber pads are compositely bonded on the top surfaces of the bottom plates at the two sides of the slot.
The utility model has the advantages and the technical effect be:
the utility model discloses a combination hoist for hoisting I-steel, through the cooperation of the resistance couple that the object was pressed from both sides and is adorned at the I-steel both ends and hoist the I-steel, this design makes I-steel hoist and mount the construction no longer receive the length and the width influence of I-steel self, can not receive the hoist size restriction, extensively be applicable to the hoist and mount construction of various model I-steel; the safety pull belt is wound and oppositely pulled to fix the two resistance hooks, so that the phenomenon that the I-shaped steel is vibrated due to factors such as high-altitude wind resistance and the like, and the two resistance hooks slide backwards to loosen the I-shaped steel is avoided; the friction resistance between the top surface of the bottom plate of the resistance hook and the bottom surface of the transverse plate at the top of the joist steel is increased through the rubber pad, the hoisting safety coefficient is improved, the bottom plate is movably inserted into the vertical plates at the two end surfaces of the joist steel through the slots, the torsional sliding between the hook and the end surface of the joist steel in the hoisting process is effectively avoided, the hoisting stability is improved, the lifting hook of the crane is connected through the hoisting hole and symmetrically hoisted at the two ends of the joist steel in an inclined opposite-pulling mode, the horizontal hoisting of the joist steel can be ensured, and the problem that the joist steel and the lifting.
The utility model discloses a I-steel hoists and uses combination hoist, its simple structure, convenient to use, safe stretching strap dismouting of being convenient for is adjusted, and the resistance couple plug installation of being convenient for has solved the relative slip problem of I-steel and couple on the basis of solving couple size problem, is a combination hoist for I-steel hoist and mount that has higher creativity.
