Description

Technical Field

[0001] This utility model relates to the field of electric shovel technology, and in particular to a bucket gate structure for an electric shovel bucket. Background Technology

[0002] The open-pit electric shovel includes a bucket and a bucket gate. An upper latch frame and a lower latch frame are provided on the outer wall surface of the bucket gate. The upper latch frame is located above the lower latch frame. An upper connecting hole is provided between the upper latch frame and the outer wall surface of the bucket gate, and a lower connecting hole is provided between the lower latch frame and the outer wall surface of the bucket gate. A latch connection hole is provided at the bottom of the bucket. When the latch installed between the upper and lower connecting holes moves downward and inserts into the latch connection hole at the bottom of the bucket, the bucket gate closes the bucket. When the latch moves upward and disengages from the latch connection hole at the bottom of the bucket, the bucket can be opened.

[0003] Because of the large size of the shovel gate and the large distance between the upper and lower latch frames, the impact load of the ore and rock on the latch during the digging of the electric shovel bucket is mainly transferred to the upper and lower latch frames. This can easily cause the upper and lower latch frames to bend, deform, or even be damaged, reducing the service life of the shovel gate. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a bucket gate structure for an electric shovel bucket that is easy to use and has a long service life.

[0005] The technical solution adopted by this utility model to solve its technical problem is: the bucket gate structure of the electric shovel bucket includes a bucket gate and a door bolt. An upper door bolt frame and a lower door bolt frame are provided on the outer wall surface of the bucket gate. The upper door bolt frame is located above the lower door bolt frame. An upper connecting through hole is provided between the upper door bolt frame and the outer wall surface of the bucket gate. A lower connecting through hole is provided between the lower door bolt frame and the outer wall surface of the bucket gate. It also includes a door bolt slide rail. The door bolt slide rail is located between the upper door bolt frame and the lower door bolt frame. A slide rail through hole is provided between the door bolt slide rail and the outer wall surface of the bucket gate. The door bolt passes through the upper connecting through hole, the slide rail through hole, and the lower connecting through hole in sequence.

[0006] Furthermore, the door latch slide is detachably connected to the hopper door via connecting bolts.

[0007] Furthermore, the upper latch frame, lower latch frame, and latch slide are all made of high manganese steel.

[0008] Furthermore, the latch is arranged vertically, passing through the upper connecting through hole, the slide through hole, and the lower connecting through hole in sequence.

[0009] Furthermore, the latch is connected to both the upper and lower connecting holes using a clearance fit.

[0010] Furthermore, the latch is rectangular in shape, and the cross-sections of the upper connecting through hole, the slide through hole, and the lower connecting through hole are all rectangular.

[0011] Furthermore, lubrication structures are provided between the latch and the upper connecting through hole, the slide through hole, and the lower connecting through hole.

[0012] Furthermore, the inner wall surfaces of the upper connecting through hole, the slide through hole, and the lower connecting through hole are all provided with a buffer protective layer.

[0013] The beneficial effects of this utility model are as follows: By providing a latch slide rail, which is located between the upper and lower latch frames, and a slide rail through hole is provided between the latch slide rail and the outer wall surface of the sluice gate, the latch passes through the upper connecting through hole, the slide rail through hole, and the lower connecting through hole in sequence. The latch slide rail plays a role in fixing and limiting the latch, and can withstand a certain load transmitted from the latch, thereby reducing the load on the upper and lower latch frames, reducing the possibility of damage to the upper and lower latch frames, effectively increasing the service life of the upper and lower latch frames, and thus increasing the service life of the sluice gate structure; furthermore, the latch slide rail can guide the latch from the upper connecting through hole into the lower connecting through hole, making it more convenient to use and conducive to large-scale use.

[0015] The markings are: 1. Doorway; 2. Door bolt; 3. Upper door bolt frame; 4. Lower door bolt frame; 5. Door bolt slide. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1 As shown, the bucket gate structure of the electric shovel bucket of this utility model includes a bucket gate 1 and a latch 2. An upper latch frame 3 and a lower latch frame 4 are provided on the outer wall surface of the bucket gate 1. The upper latch frame 3 is located above the lower latch frame 4. An upper connecting through hole is provided between the upper latch frame 3 and the outer wall surface of the bucket gate 1, and a lower connecting through hole is provided between the lower latch frame 4 and the outer wall surface of the bucket gate 1. It also includes a latch slide 5, which is located between the upper latch frame 3 and the lower latch frame 4. A slide through hole is provided between the latch slide 5 and the outer wall surface of the bucket gate 1. The latch 2 is arranged to pass through the upper connecting through hole, the slide through hole, and the lower connecting through hole in sequence.

[0018] The bolt slide 5 serves to fix and limit the bolt 2, and can withstand a certain load transmitted from the bolt 2, thereby reducing the load on the upper bolt frame 3 and the lower bolt frame 4, reducing the possibility of damage to the upper bolt frame 3 and the lower bolt frame 4, effectively increasing the service life of the upper bolt frame 3 and the lower bolt frame 4, and thus increasing the service life of the gate structure; in addition, the bolt slide 5 can guide the bolt 2 to be inserted from the upper connecting hole into the lower connecting hole, making it more convenient to use and conducive to large-scale use.

[0019] Specifically, to further extend the service life of the gate structure, the upper latch frame 3, the lower latch frame 4, and the latch slide 5 are all made of high-manganese steel. High-manganese steel has high strength and wear resistance, resulting in good performance.

[0020] To facilitate the operation of the latch 2, it is vertically arranged to pass through the upper connecting through hole, the sliding through hole, and the lower connecting through hole in sequence. Furthermore, the latch 2 is fitted with each of these holes using a clearance fit. Lubrication structures, such as lubricating oil or grease, are provided between the latch 2 and each of these holes.

[0021] To improve the effectiveness of the latch 2, the latch 2 is preferably rectangular in shape, and the cross-sections of the upper connecting through hole, the slide through hole, and the lower connecting through hole are all rectangular.

[0022] To reduce the impact damage of the latch 2 on the upper latch frame 3, the lower latch frame 4, and the latch slide 5, a buffer protective layer is provided on the inner wall surface of the upper connecting through hole, the inner wall surface of the slide through hole, and the inner wall surface of the lower connecting through hole. The buffer protective layer is preferably made of rubber.

[0023] The door latch slide 5 can be fixed to the outer wall of the dam gate 1 by welding, but welding makes it inconvenient to replace the door latch slide 5. In order to facilitate the repair or replacement of the door latch slide 5 after damage, the door latch slide 5 is detachably connected to the dam gate 1 by connecting bolts.
