Description

Counterweight lifting hook

Technical Field

The utility model belongs to the technical field of lifting equipment, and particularly relates to a counterweight lifting hook.

Background

The integrated processing plant slag treatment operation area adopts a liquid state in-tank heat stewing method to treat converter slag, and in the operating procedure of the slag treatment process, a slag tank containing the slag is required to be hung to a tank padding area by a 63-ton overhead travelling crane; the slag pot is of a lower closing-in structure, a V-shaped hook hole of the slag pot is arranged at the lower part of the slag pot, and in the hoisting process, a hook head of a lifting hook is required to be pushed into the V-shaped hook hole at the lower part of the slag pot manually; in addition, as the self weight of the lifting hook is large, in the natural sagging process, in order to keep the gravity center and the lifting point on the same plumb line, the hook part of the lifting hook can rotate 30 degrees relative to the plumb line, and under the natural sagging condition, the hook part of the lifting hook can generate a distance of 0.5 meter with the V-shaped lifting hole of the slag pot; the operation time is long because of the heavy weight of the lifting hook and poor manual operation accuracy, the operation safety cannot be ensured, and the requirements of the modern production process cannot be met; manual assistance is needed in the operation process, which is not beneficial to the requirements of cost reduction and synergy.

Disclosure of utility model

Aiming at the problems existing in the prior art, the utility model provides a counterweight lifting hook.

The utility model is realized in such a way that the counterweight lifting hook comprises a lifting hook body, wherein the lifting hook body comprises a lifting point and a connecting arm which is arranged in a downward extending way along the lifting point, and the lower end part of the connecting arm is provided with a hook part to one side; and the counterweight structure is connected with the lifting point and is used for forcing the hook part to rotate towards the lifted object.

Further, the counterweight structure comprises a counterweight arm fixedly connected with the lifting point, and the counterweight arm is perpendicular to the connecting arm.

Further, the counterweight arm is made of Q345 plates with the thickness of 100 mm.

Further, the balancing weight arm other end is connected with the balancing weight, the balancing weight arm is the disc structure, disc structure diameter is 280mm, and is 40mm thick.

Further, the balancing weight is formed by processing Q plates.

Further, an anti-slip layer is arranged on the upper surface of the hook part, and the anti-slip layer is used for preventing the hook part from falling off from a hanging hole of the slag pot in the slag pot hanging process.

The utility model has the advantages and technical effects that: because the counterweight structure of the lifting hook is arranged, the lifting hook is directly hung into the hanging hole of the slag pot by the crown block, and only the crown block driver needs to operate the crown block; the utility model can meet the field production requirement, and the overhead travelling crane is adopted to replace the manual hook, so that the working intensity of workers is greatly relieved, the operation safety is improved, and the working capacity of the overhead travelling crane is effectively improved.

Drawings

Fig. 1 is a schematic structural diagram provided in an embodiment of the present utility model.

In the figure: 1. a hook body; 2. a hanging point; 3. a connecting arm; 4. a hook portion; 5. a counterweight arm; 6. balancing weight; 7. a counterweight structure; 8. an anti-slip layer.

Detailed Description

The present utility model will be described in further detail with reference to the following examples in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Referring to fig. 1, a counterweight hook comprises a hook body 1, wherein the hook body 1 is made of a Q345 plate material; the lifting hook comprises a lifting hook body 1, a lifting point 2 connected with a crane steel rope and a connecting arm 3 extending downwards along the lifting point 2, wherein the lower end part of the connecting arm 3 is provided with a hook part 4 to one side; the upper surface of the hook part 4 is provided with an anti-slip layer 8, and the anti-slip layer 8 is used for preventing the hook part 4 from falling off from a hanging hole of the slag pot in the slag pot hanging process.

The counterweight structure 7 is arranged on the other side of the connecting arm 3, and the counterweight arm 5 is arranged vertically to the connecting arm 3; and is welded and connected with the hanging point 2; the counterweight structure 7 is used for forcing the hook 4 to rotate towards the hoisted object; the counterweight structure 7 comprises a counterweight arm 5 welded with the hanging point 2, and the counterweight arm 5 is made of a Q345 plate material with the thickness of 100 mm; the other end of the counterweight arm 5 is welded with a counterweight 6, the counterweight arm 5 is of a disc structure, the diameter of the disc structure is 280mm, and the thickness of the disc structure is 40mm; the balancing weight 6 is formed by processing a Q345 plate.

Due to the arrangement of the counterweight structure 7, after the counterweight lifting hook is installed, the hook part 4 rotates along the lifting point 2 and rotates 30 degrees towards the opening side of the hook part 4; the extending distance of the hook part 4 after rotation is 0.5m close to the lifted object relative to the position in the natural sagging state before the weight is not added; when the overhead traveling crane moves the lifting hook body 1 to the side of the slag ladle, the hook part 4 just aims at the slag ladle lifting hole, a crane driver can operate the hook by himself so as to meet the field production requirement, and the overhead traveling crane is adopted to replace the manual hook, so that the labor intensity is greatly relieved, the operation safety is improved, and the operation capacity of the overhead traveling crane is effectively improved.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
