Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature Daqu cake transfer equipment, in particular to a rotary lockable in-bin telescopic conveyor. Background Art

[0002] After the high-temperature Daqu is fermented in the fermentation bin, it is manually transferred to the chute opening of the fixed dry Daqu bin and poured. The Daqu cakes slide into the corresponding dry Daqu bin through the dry Daqu bin chute. However, due to the floor height and the space limitation of the dry Daqu bin, the area covered by the chute in the dry Daqu bin is limited. It is still necessary for workers to operate in the dry Daqu bin to transfer and level the Daqu cakes secondarily. During the loading of the dry Daqu bin, there is a lot of dust in the bin, resulting in a poor working environment and a large investment in labor costs.

[0003] At present, a rotary telescopic belt conveyor can be used to convey the Daqu cakes, which is convenient for loading into the bin. However, during the use process, since the telescopic belt conveyor needs to extend and the Daqu cakes are heavy, it is easy to cause excessive load on one side of the slewing support close to the extended part, damaging the slewing support or causing the telescopic belt conveyor to tilt;

[0004] Secondly, under the condition of excessive pressure, it is easy to cause the telescopic belt conveyor to rotate and deviate on the horizontal plane, affecting the conveying effect and the accuracy of loading into the bin. Content of the Utility Model

[0005] The utility model provides a rotary lockable in-bin telescopic conveyor, aiming to solve the problems that the slewing support is easily damaged due to excessive load during the conveying of Daqu cakes by the rotary telescopic belt conveyor, and the telescopic belt conveyor is prone to rotate and deviate, affecting the conveying effect.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0007] A rotary lockable in-bin telescopic conveyor includes a moving mechanism and a telescopic belt conveyor. A inspection platform is arranged on the top of the moving mechanism. A slewing mechanism is arranged on the top of the middle position of the inspection platform. The telescopic belt conveyor is rotationally matched with the inspection platform in the horizontal direction through the slewing mechanism. Limiting frames are respectively arranged on both sides of the telescopic belt conveyor. Rotatable locking mechanisms are arranged on both sides of the top of the inspection platform, and the locking mechanisms correspond to the limiting frames one by one. The locking mechanisms form a releasable locking fit with the corresponding limiting frames.

[0008] Preferably, the limiting frames are arranged at the four corners of the bottom frame of the telescopic belt conveyor, and the four limiting frames are symmetrically arranged in pairs with respect to the middle position of the telescopic belt conveyor.

[0009] More preferably, the limiting frames each include channel steels arranged vertically. The top of the channel steel is fixedly fitted with the bottom frame of the telescopic belt conveyor, and a limiting rod is arranged in a groove at the bottom of the channel steel.

[0010] Furthermore, the locking mechanism is symmetrical about the middle position of the telescopic belt conveyor.

[0011] Even further, the locking mechanisms each include a pair of oppositely arranged articulated swing arms, and the articulated swing arms correspond one by one to the limiting frames on the same side. The bottoms of the articulated swing arms are each articulated with the inspection platform in the vertical direction through a second hinge. A connecting rod is arranged between the tops of the articulated swing arms, and the pair of articulated swing arms form a linkage through the connecting rod. An electric push rod with both ends articulated is arranged between the connecting rod and the inspection platform. Grooves are arranged on the sides of the tops of the articulated swing arms away from the electric push rod, and the grooves form a releasable locking fit with the limiting rods of the corresponding limiting frames.

[0012] Specifically, the electric push rod is located on one side close to the middle position of the inspection platform. The fixed end of the electric push rod is articulated with the inspection platform in the vertical direction through a first hinge, and the output end of the electric push rod is articulated with the middle position of the connecting rod in the vertical direction through a first hinge.

[0013] Preferably, the moving mechanism includes an equipment moving frame arranged below the inspection platform. Driving rollers are rotatably arranged at the four corners of the bottom of the equipment moving frame. A corresponding reduction motor is arranged on one side of each driving roller, and the driving roller forms a linkage with the output shaft of the corresponding reduction motor.

[0014] More preferably, a maintenance platform inclined ladder is arranged on one side of the equipment moving frame.

[0015] Furthermore, the slewing mechanism includes a slewing bearing arranged at the top of the middle position of the inspection platform. The middle position of the bottom of the telescopic belt conveyor is rotationally fitted with the inspection platform in the horizontal direction through the slewing bearing. A slewing gear is arranged outside the slewing bearing, and the slewing gear is concentric and coaxial with the slewing bearing and forms a linkage. A driving motor is arranged on one side of the slewing bearing. A driving gear is arranged on the output shaft of the driving motor, and the driving gear meshes with the slewing gear to form a gear transmission.

[0016] Advantages of the present utility model:

[0017] With the present utility model, when the telescopic belt conveyor rotates to a set position, the locking mechanism can form a locking fit with the limiting frame on the telescopic belt conveyor. On the one hand, the position of the telescopic belt conveyor is locked to prevent rotational deviation during the conveying process. Secondly, the limiting frame can be limited and supported by the locking mechanism, relieving the force on the slewing bearing and avoiding damage to the slewing bearing. Description of the drawings

[0029] As follows, the embodiments will be further described with reference to the accompanying drawings.

[0030] As Figures 1 to 4 shown, as a preferred Embodiment 1, a rotatable and lockable telescopic conveyor for feeding into a bin includes a moving mechanism 2 and a telescopic belt conveyor 4. A inspection platform 1 is provided at the top of the moving mechanism 2. A rotary mechanism 3 is provided at the top of the middle position of the inspection platform 1. The telescopic belt conveyor 4 is rotationally matched with the inspection platform 1 in the horizontal direction through the rotary mechanism 3. Limit frames 5 are respectively provided on both sides of the telescopic belt conveyor 4. Rotatable locking mechanisms 6 are provided on both sides of the top of the inspection platform 1, and the locking mechanisms 6 correspond to the limit frames 5 one by one. The locking mechanism 6 forms a releasable locking fit with the corresponding limit frame 5.

[0031] During use, when the telescopic belt conveyor 4 rotates to a set position, the locking mechanism 6 forms a locking fit with the limit frame 5. While limiting the telescopic belt conveyor 4, it also assists in supporting the telescopic belt conveyor 4, preventing the slewing mechanism 3 from being overloaded and unevenly stressed, which may cause damage to the slewing mechanism 3.

[0032] As a preferred embodiment 2, the limit frames 5 are arranged at the four corners of the underframe of the telescopic belt conveyor 4, and the four limit frames 5 are symmetrically arranged in pairs with respect to the middle position of the telescopic belt conveyor 4. This facilitates ensuring force balance and the effects of limiting and locking.

[0033] Each of the limit frames 5 includes a vertically arranged channel steel 501. The top of the channel steel 501 forms a fixed fit with the underframe of the telescopic belt conveyor 4, and a limit rod 502 is provided in a groove at the bottom of the channel steel 501. During limiting, the locking mechanism 6 locks the limit rod 502 of the channel steel 501. After locking the four limit frames 5, the position of the telescopic belt conveyor 4 can also be restricted.

[0034] The locking mechanism 6 is symmetric with respect to the middle position of the telescopic belt conveyor 4. This facilitates ensuring force balance.

[0035] Each of the locking mechanisms 6 includes a pair of oppositely arranged articulated swing arms 603, and the articulated swing arms 603 correspond one by one to the limit frames 5 on the same side. The bottoms of the articulated swing arms 603 are each articulated with the inspection platform 1 in the vertical direction through a second hinge 606. A connecting rod 604 is provided between the tops of the pair of articulated swing arms 603, and the pair of articulated swing arms 603 form a linkage through the connecting rod 604. An electric push rod 601 with both ends articulated is provided between the connecting rod 604 and the inspection platform 1. Grooves 605 are provided on the sides of the tops of the articulated swing arms 603 away from the electric push rod 601, and the grooves 605 form a releasable locking fit with the limit rods 502 of the corresponding limit frames 5.

[0036] During locking, the electric push rod 601 extends to provide a driving force, pushing the connecting rod 604. Thus, the connecting rod 604 drives the articulated swing arms 603 to rotate upward around the second hinge 606, so that the grooves 605 are snapped onto the limit rods 502. At this time, the limit rods 502 are limited and received in the grooves 605 to complete the locking fit.

[0037] During unlocking, the electric push rod 601 retracts to provide a driving force, pulling the connecting rod 604. Thus, the connecting rod 604 drives the articulated swing arms 603 to rotate downward around the second hinge 606, so that the grooves 605 are disengaged from the limit rods 502. At this time, the limit rods 502 and the grooves 605 are unlocked.

[0038] The electric push rod 601 is located on one side near the middle position of the inspection platform 1. The fixed end of the electric push rod 601 is hinged with the inspection platform 1 in the vertical direction through a first hinge 602. The output end of the electric push rod 601 is hinged with the middle position of the connecting rod 604 in the vertical direction through the first hinge 602, ensuring that the telescopic movement of the electric push rod 601 can drive the connecting rod 604.

[0039] As a preferred embodiment 3, the moving mechanism 2 includes an equipment moving frame 201 provided below the inspection platform 1. Driving rollers 202 are rotatably provided at the four corners of the bottom of the equipment moving frame 201. A corresponding reduction motor 203 is provided on one side of each driving roller 202, and the driving roller 202 is in linkage cooperation with the output shaft of the corresponding reduction motor 203, ensuring the overall movement of the device.

[0040] An inspection platform inclined ladder 2011 is provided on one side of the equipment moving frame 201, facilitating the staff to climb onto the inspection platform 1.

[0041] As a preferred embodiment 4, the slewing mechanism 3 includes a slewing bearing 301 provided at the top of the middle position of the inspection platform 1. The bottom middle position of the telescopic belt conveyor 4 is rotationally matched with the inspection platform 1 in the horizontal direction through the slewing bearing 301. A slewing gear 302 is provided outside the slewing bearing 301, and the slewing gear 302 is concentric and coaxial with the slewing bearing 301 and forms a linkage cooperation. A driving motor 303 is provided on one side of the slewing bearing 301. A driving gear 304 is provided on the output shaft of the driving motor 303, and the driving gear 304 meshes with the slewing gear 302 to form a gear transmission cooperation. By providing driving force through the driving motor 303, the slewing bearing 301 is smoothly rotated by using gear transmission to complete the slewing operation.

[0042] The working principle of the present utility model:

[0043] During use, when the telescopic belt conveyor 4 rotates to the set position, the locking mechanism 6 forms a locking cooperation with the limiting frame 5, limiting the telescopic belt conveyor 4 and at the same time assisting in supporting the telescopic belt conveyor 4, avoiding damage to the slewing mechanism 3 caused by excessive and uneven force on the slewing mechanism 3.
