[0001] The present application relates to the field of hoist, in particular to a bucket elevator. BACKGROUND

[0002] The bucket elevator is often used to transport bulk materials from low to high, or to transport materials from one process to another. The working principle of the bucket elevator is to drive the conveying chain to rotate by the conveying chain wheel, and a plurality of bucket material handling devices are fixed on the conveying chain. These handling devices will be lifted from low to high under the driving of the conveying chain wheel, and unloaded at high. Therefore, the bucket elevator is suitable for conveying bulk materials, such as powder, granular material and small block material. The shell or housing side of the bucket elevator is usually provided with an inspection observation door. When the equipment is maintained or cleaned, the inside of the shell can be accessed for related work by opening the inspection observation door, and the working condition of the equipment inside can also be observed through the observation door to discover and solve equipment failures in time. The existing inspection door of the bucket elevator is generally arranged on the side or top of the housing. If the internal components with inconsistent height with the inspection door need to be inspected or maintained, it is not convenient enough. For example, the Chinese patent application file with the application number CN201910114053.9 discloses a bucket elevator. The inspection door of the bucket elevator is arranged on the vertical annular track, and the internal structure of the bucket elevator is very high. The internal inspection or maintenance cannot be well achieved through the inspection door alone. SUMMARY

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings. Embodiment

[0032] As Figures 1 to 11As shown, a bucket elevator includes a feeding port 1, a discharging port 2, a shell 3, a driving wheel, a driven wheel, a transmission motor, a chain plate and a lifting bucket 4, wherein the shell 3 is provided with a rotating maintenance part, the rotating maintenance part includes a horizontal sliding window, a translation window plate 5, a panel slot and a rotating pull block, the horizontal sliding window is a rectangular through slot penetrating through the shell 3, the panel slot is a rectangular straight slot recessed inward from the vertical wall surface of the two sides of the horizontal sliding window, the translation window plate 5 is a rectangular square plate inserted into the panel slot, the inner side end surface of the translation window plate 5 is connected to the bottom surface of the panel slot through a spring, the outer side end surface of the translation window plate 5 is provided with a clamping block slot and a clamping limiting plate, the clamping block slot is a semicircular notch recessed inward from the outer side end surface of the translation window plate 5, and the clamping limiting plate is an arc-shaped flat strip extending outward from the two side edges of the clamping block slot, the rotating pull block includes a rotating block 6, a rotating rod 7 and an extension rod, the rotating block 6 is a semicircular block plate, the rotating block 6 is provided with a pair of insertion protrusions and a pair of insertion grooves, the insertion protrusion is a protruding block extending outward from the flat wall surface of the rotating block 6, the insertion groove is a recessed groove recessed inward from the flat wall surface of the rotating block 6, the insertion protrusion and the insertion groove are symmetrically distributed with respect to the central axis of the rotating block 6, the extension rod is a straight rod extending outward perpendicular to the screen where the rotating block 6 is located, the rotating rod 7 is a straight rod extending outward from the outer end of the extension rod, and the extension direction of the rotating rod 7 is consistent with the flat wall surface of the rotating block 6. The rotating maintenance parts are vertically and spacedly arranged on the shell 3 of the bucket elevator, the rotating rod 7 can be used as a force point to climb upward, so that the internal conditions of the shell 3 corresponding to the rotating maintenance part at the required height can be specifically viewed. Specifically, when the rotating rod 7 is in a horizontal posture, the upper and lower rotating blocks 6 are combined by inserting the insertion protrusions into the insertion grooves respectively, and the rotating block 6 cannot be horizontally moved through the rotating rod 7 at this time. When the rotating block 6 needs to be horizontally moved, the rotating rod 7 needs to be rotated, so that the extension rod drives the rotating block 6 to rotate by ninety degrees until the two rotating blocks 6 in the upper and lower positions become in the left and right positions. At this time, the rotating block 6 on the two sides can be reversely pushed by applying force to the rotating rod 7, the rotating block 6 pushes the translation window plate 5 through the clamping block slot, so that the translation window plate 5 moves into the panel slot, thereby opening the horizontal sliding window, and the internal conditions of the shell 3 can be viewed by personnel; when the translation window plate 5 needs to be closed, the two rotating blocks 6 that are moved towards each other are combined and then rotated by ninety degrees, so that the rotating blocks 6 cannot be separated in the horizontal direction, thereby ensuring that the translation window plate 5 is stable at this time.

[0033] The rotating rod 7 is also provided with a relief part 8 for improving surface roughness.

[0034] The relief part 8 is a straight strip-shaped rectangular rod protruding outward from the surface of the rotating rod 7, and the extension direction of the relief part 8 is consistent with the extension direction of the rotating rod 7. The relief part 8 is beneficial for climbing and stepping, and can make the force point more stable when the staff climbs upward through the rotating rod 7, and can better adjust the angle of the rotating block 6 and better push the translation window plate 5.

[0035] The surface of the convex part 8 also has anti-off grooves 9, which are grooves recessed inward from the surface of the convex part 8, and the anti-off grooves 9 are distributed on the convex part 8 at intervals. When the staff steps on the rotating rod 7, the anti-off grooves 9 can achieve anti-skid, avoiding the shoe sole from slipping on the surface of the rotating rod 7 during the climbing process.

[0036] The anti-off grooves 9 are formed by converging the opposite inclined planes, and the cross section is like an inverted triangle. The shape of the inverted triangle can provide better support for extrusion on both sides.

[0037] The shell 3 also has a locking part for keeping the rotating pull block stable.

[0038] The locking part includes a window side protruding rod 10, a dial ring, a lock rod and a lock hook 11. The window side protruding rod 10 is a round rod extending horizontally outward from the surface of the shell 3 at the side of the horizontal sliding window, the dial ring is a round ring sleeved on the window side protruding rod 10, the lock rod is a straight rod extending outward from the side of the dial ring, and the lock hook 11 is a hook extending outward from the end of the lock rod. When the rotating rod 7 is forced to move the translation window plate 5 to the inside of the front plate groove, the dial ring is rotated, so that the lock hook 11 hooks the extension rod to prevent the translation window plate 5 from resetting under the action of the spring force. In particular, the window side protruding rod 10 can also serve as a supporting rod.

[0039] The shell 3 also has a bracket rod protruding strip 12, which is a rectangular protruding block protruding horizontally outward from the surface of the shell 3, and the bracket rod protruding strip 12 is located on both sides of the dial ring. When the dial ring is rotated, the lock rod can be rotated to the bracket rod protruding strip 12 on both sides to complete the stabilization of the posture of the lock rod.

[0040] The bracket rod protruding strip 12 has a fitting groove 13, which is a groove recessed inward from the upper surface of the bracket rod protruding strip 12. The fitting groove can stabilize the lock rod, prevent the dial ring from shaking on the window side protruding rod 10, and optimize the stress of the lock rod.
