Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of crane hooks, in particular to a bridge crane hook stabilizing device. BACKGROUND

[0002] The bridge crane is a hoisting device for material lifting over the workshop, warehouse and material yard, mainly composed of a bridge, a cart moving mechanism, a trolley moving mechanism and an electrical control mechanism. Before use, the material and the hook are connected. During use, the crane is driven by the cart motor to move longitudinally along the track on both sides of the workshop. The trolley and the lifting mechanism are driven by the trolley motor to move laterally along the track on the bridge. When lifting the weight, the lifting motor is driven to move vertically up and down. Through the cooperation of the three movements, the material can be transferred between any points in the moving space.

Detailed Implementation

[0019] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0020] This application discloses a hook stabilizing device for a bridge crane.

[0021] See Figures 1-4 The bridge crane hook stabilizing device includes a connector 1 and a hook body 3. A connecting shaft 2 is fixedly connected to the bottom of the connector 1, and the hook body 3 is fixedly connected to the bottom of the connecting shaft 2. Positioning frames 13 are symmetrically fixedly connected to both sides of the hook body 3. A rotating positioning component is rotatably connected inside the positioning frame 13. A mounting box 4 is fixedly connected to the outside of the hook body 3. A limit component is rotatably connected inside the mounting box 4, and a reset component is fixedly connected to one side of the mounting box 4.

[0022] Furthermore, the rotation positioning assembly includes a positioning gear 6, which is rotatably connected to the interior of two positioning frames 13. A shaft is fixedly mounted between the two positioning frames 13 and passes through the middle of the positioning gear 6. A connecting slot 14 is provided on the side of the positioning gear 6. When installing the connecting rope, the connecting rope is placed inside the connecting slot 14 of the positioning gear 6, and the connecting rope is pulled down to make the positioning gear 6 rotate until the connecting rope contacts the positioning frame 13.

[0023] Further, the limiting assembly comprises a fixed main shaft 5 fixedly connected to the middle part of the mounting box 4, a positioning gear 6 rotatably connected in the mounting box 4, a rotating clamping cylinder 7 fixedly connected to one side of the positioning gear 6, a sliding clamping cylinder 8 meshingly connected to one side of the positioning gear 6, and a plurality of limiting tubes 10 fixedly connected to the outer side of the sliding clamping cylinder 8 at equal angles. The rotating clamping cylinder 7 is driven to rotate when the positioning gear 6 rotates, and the sliding clamping cylinder 8 is pushed away when the rotating clamping cylinder 7 rotates. The positioning gear 6 stops rotating after the rope is fixed in position, and the positioning rack 13 contacts and blocks the movement of the rope at this time.

[0024] Further, the rotating clamping cylinder 7 penetrates the side wall of the mounting box 4, and the rotating clamping cylinder 7 and the positioning gear 6 are both rotatable along the fixed main shaft 5. The inclined tooth grooves 15 at the end of the rotating clamping cylinder 7 and the sliding clamping cylinder 8 are meshed with each other.

[0025] Further, the resetting assembly comprises a fixed mounting seat 9 fixedly connected to one end of the fixed main shaft 5 away from the mounting box 4, and a resetting compression spring 12 sleeved at the end of the fixed main shaft 5. The two ends of the resetting compression spring 12 are in contact with the end faces of the sliding clamping cylinder 8 and the fixed mounting seat 9, respectively. When the rotating clamping cylinder 7 is rotated to push the sliding clamping cylinder 8 away, the resetting compression spring 12 is compressed under force, and then pushes the sliding clamping cylinder 8 back to its original position by its own elastic force, so as to keep meshing with the rotating clamping cylinder 7 and prevent the rotating clamping cylinder 7 from rotating back.

[0026] Further, a plurality of guide rods 11 are fixedly connected to the side of the fixed mounting seat 9 close to the mounting box 4 at equal angles, and the guide rods 11 penetrate the limiting tubes 10 and are fixedly connected to the side of the mounting box 4. The sliding clamping cylinder 8 slides along the guide rods 11.

[0027] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, equivalent changes made on the basis of the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
