Description

Technical Field

[0001] This utility model relates to the field of slag grabbing bucket technology, specifically to an automatic slag flushing device for a slag grabbing bucket. Background Technology

[0002] A large amount of waste slag is generated during the steel smelting process. The waste slag is moved by grabbing buckets. The grabbing buckets grab the molten waste slag and move it to the slag cooling tank for cooling and storage.

[0003] During the process of grabbing waste residue, waste residue can easily remain on the support beam of the grab bucket. If too much waste residue accumulates, especially at the bottom of the pulling mechanism, it will affect the closing of the grab bucket, causing it to malfunction and requiring manual cleaning, increasing the workload of personnel and reducing production efficiency.

[0004] In the existing technology, a water tank is installed on the support beam. As the slag grabbing bucket leaves the slag-suppressing tank, the water in the tank flows out to wash the waste residue adhering to the support beam. However, because the slag grabbing bucket rises slowly, the water in the tank flows out from the bottom to wash the support beam as soon as it emerges from the water surface. At this time, the support beam has not yet emerged from the water surface, and the water in the tank is blocked by the water on the support beam, resulting in poor washing effect. Sometimes, multiple washes are required to clean the waste residue off the support beam, which needs to be improved. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background art and to provide an automatic slag flushing device for a slag grabbing bucket.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: an automatic slag flushing device for a slag grabbing bucket, including a slag grabbing bucket body, the slag grabbing bucket body including a support beam and a push-pull device disposed above the support beam, the push-pull device is hinged to a bucket body that is rotatably connected to the support beam, and the support beam is provided with symmetrically arranged slag flushing devices.

[0007] The slag flushing device includes a box body mounted on a supporting beam. The side wall of the box body has water inlet and outlet holes. A floating device is connected to the box body by a rope. The bottom of the box body has an opening facing the supporting beam. A door that opens outward is hinged in the opening. The door has a first lug. The box body has a second lug and a third lug that cooperate with the first lug. A locking device that extends into the second lug and locks the door is movable in the first lug. The floating device has an opening rod that passes through the third lug and abuts against the locking device.

[0008] As an improvement, the water inlet and outlet holes are located close to the door body.

[0009] As an improvement, the locking device includes a rod body disposed in a first ear, a lock head disposed in a second ear at the top of the rod body, and a float ball disposed at the bottom of the rod body that can push the rod body and the lock head upward.

[0010] As an improvement, the floating device includes a rectangular counterweight plate disposed inside the box, a rectangular float on the top of the rectangular counterweight plate, and an opening rod disposed on the rectangular counterweight plate.

[0011] As an improvement, the rectangular counterweight plate is provided with a connecting plate, one end of the pull rope is fixed to the connecting plate, and the other end is fixed to the center of the box.

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] 1. The locking device can lock the door, and the floating device can move downward when the water in the box decreases, which will drive the opening rod to move downward. The opening rod can push the locking device open, thereby opening the door. The water in the box flows out from the opening to wash the waste residue on the support beam.

[0014] 2. The inlet and outlet holes allow water to flow between the inside and outside of the tank. When the slag grabbing bucket body descends into the water in the slag-suppressing tank, water can enter the tank through the inlet and outlet holes and the holes on the rectangular counterweight plate. When the tank is full, the float on the locking device drives the locking device to move upward and lock the door. When the slag grabbing bucket body moves upward and leaves the slag-suppressing tank, the water in the tank flows out from the inlet and outlet holes, the floating device moves downward, and the opening rod pushes open the locking device, allowing water to flow out and wash the supporting beam.

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0021] Combined with appendix Figure 1-4 An automatic slag flushing device for a slag grabbing bucket includes a slag grabbing bucket body 1. The slag grabbing bucket body 1 includes a support beam 2 and a push-pull device 3 disposed above the support beam 2. A bucket body 4 that is hinged to the push-pull device 3 and rotatably connected to the support beam 2 is provided. A slag flushing device 5 is symmetrically arranged on the support beam 2.

[0022] The slag flushing device 5 includes a box 6 mounted on a supporting beam 2. The side wall of the box 6 has water inlet and outlet holes 7, which are located near the door 11. A floating device 9 is connected inside the box 6 by a rope 8. The bottom of the box 6 has two openings 10 facing the supporting beam 2. A door 11 that opens outward is hinged inside the opening 10. The door 11 has a first ear 12. The box 6 has a second ear 13 and a third ear 14 that cooperate with the first ear 12. A locking device 15 that extends into the second ear 13 and locks the door 11 is movably mounted inside the first ear 12. The floating device 9 has an opening rod 16 that passes through the third ear 14 and abuts against the locking device 15.

[0023] When the slag grabber body 1 is immersed in water, the water in the slag simmering tank enters the tank 6 through the inlet / outlet holes 7 and the opening at the top of the tank 6. The door 11 is squeezed tightly against the opening 10 by the external water. The locking device 15 moves upward to the second ear 13 under the buoyancy of the water to lock the door 11. The floating device 9 moves upward under the buoyancy of the water, causing the opening rod 16 to disengage from the second through hole 13 and move into the third through hole 14.

[0024] When the slag grabber body 1 is removed from the water surface, the water in the box 6 flows out through the inlet and outlet holes 7, the water level in the box 6 drops, the floating device 9 moves downward, driving the opening rod 16 to move downward, and the floating device 9 uses its own weight to squeeze the locking device 15 out of the second ear 13, the locking device 15 opens, at this time the support beam 2 has been removed from the water surface, and the water in the box 6 flows out from the opening to wash the slag on the support beam 2. Example 2

[0025] Combined with appendix Figure 4The locking device 15 includes a rod 17 disposed in the first ear 12, a lock head 18 disposed in the second ear 13 at the top of the rod 17, and a float 19 disposed at the bottom of the rod 17 that can push the rod 17 and the lock head 18 upward. The float 19 and the lock head 18 cooperate to restrict the rod 17 in the first ear 12. The float 19 moves upward under buoyancy, which drives the rod 17 and the lock head 18 to move upward. When the lock head 18 enters the second ear 13, the door 11 is locked.

[0026] The floating device 9 includes a rectangular counterweight plate 20 disposed inside the box 6, a rectangular float 21 disposed on the top of the rectangular counterweight plate 20, and an opening rod 16 disposed on the rectangular counterweight plate 20.

[0027] The rectangular counterweight plate 20 is provided with a connecting plate 22. One end of the pull rope 8 is fixed to the connecting plate 22, and the other end is fixed to the center of the box 6. The pull rope 8 can limit the movement of the floating device 9 and prevent it from falling out of the box 6.

[0028] When the water in the box 6 decreases, the floating device 9 moves downward, causing the opening rod 16 to move downward. The opening rod squeezes the lock head 18, causing the lock head 18 to disengage from the second ear 13, and the door 11 opens. Water flows out through the opening 10 to rinse the supporting beam 2.
