Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a high-load forging slag span crane. Background Art

[0002] A crane refers to a multi-action lifting machinery that vertically lifts and horizontally moves heavy objects within a certain range. It is also called an overhead crane, overhead crane, or hoist. The working characteristic of a crane is intermittent movement, that is, the corresponding mechanisms of the actions of picking up materials, transporting, and unloading work alternately in one working cycle. Cranes are being used more and more widely in forging slag spans.

[0003] When the existing high-load forging slag span crane is in use, the forging slag span east-traveling crane is 32 / 5t, and the load capacity of its auxiliary hook cannot meet the demand for turning the slag basin in production. According to the requirements of the workshop, the auxiliary hook mechanism is enlarged and upgraded, and the load capacity is increased to 10t, so as to improve the use effect of the forging slag span crane. Utility Model Content

[0004] The utility model aims to solve the problem that the auxiliary hook load of the existing equipment cannot meet the use demand of the slag basin turning in production, and proposes a high-load forging slag span crane.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a high-load forging slag span crane, comprising two main beam frames, the tops of the two main beam frames are each provided with two strip grooves, the inner surfaces of the two strip grooves are both movably embedded with T-shaped sliders, a driving motor is fixedly installed on the top of one of the T-shaped sliders, a driving rod is fixedly installed on one side of the outer wall of the driving motor, a fixing column is fixedly installed on the top of the other T-shaped slider, and the outer surface wall of the driving rod is movably inserted into the interior of the fixing column, a double pulley is fixedly sleeved on the outer surface wall of the driving rod, a steel wire rope is arranged on the outer surface wall of the double pulley, and a three-pulley assembly is fixedly installed on the bottom of the steel wire rope.

[0006] Preferably, a rotating block is fixedly mounted on the bottom of the three-pulley assembly, and a hook body is movably inserted inside the rotating block.

[0007] Preferably, forward and reverse motors are fixedly mounted on the tops of the two main beams.

[0008] Preferably, a reciprocating screw rod is fixedly installed on one side of the outer wall of the two forward and reverse motors, a limiting column is fixedly installed on the top of the two main beam frames, and the outer walls of the two reciprocating screw rods are movably inserted into the inside of the two limiting columns.

[0009] Preferably, a transverse plate is fixedly mounted on one side of the outer wall of the two main beams, and a supporting beam is fixedly mounted on the bottom of the transverse plate.

[0010] Preferably, two upright posts are fixedly installed on the top of the transverse plate, and a fixing rod is fixedly installed between opposite sides of outer walls of the two upright posts.

[0011] Preferably, the outer wall movable sleeve of the fixing rod is provided with two rotating wheels, and the outer wall of the steel wire rope is in contact with the outer walls of the two rotating wheels.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] In the utility model, the original 5t design hook group is a double pulley, and its fixed pulley is a single pulley. When the auxiliary hook load needs to be upgraded to 10t, the fixed pulley is replaced with a double pulley and re-fixed, and then the double pulley of the hook group needs to be replaced with a three-pulley assembly. Under the action of the rotating block and the hook body, after repeated demonstrations, the position of the trolley chassis is reinforced, the original motor and reducer remain unchanged, and the labor-saving multiples of the wire rope are increased by adding pulleys, so that the load of the auxiliary hook reaches the 10t use requirement, thereby improving the use effect of the forging slag span crane.

[0014] In the utility model, two forward and reverse motors are started to drive two T-shaped sliders to move back and forth on two reciprocating screw rods and move back and forth inside two strip grooves at the same time, thereby improving the stability of the horizontal movement of the double pulleys, the three-pulley assembly and the hook body. Then, the driving motor is started to drive the driving rod and the double pulleys to rotate, thereby realizing vertical movement of the three-pulley assembly and the hook body, which not only enables the auxiliary hook to meet the use requirement of 10t, but also improves the use effect of the forging slag span crane.
