Description

Technical Field

[0001] This application relates to the technical field of chain conveyors, and in particular to a flip-type chain conveyor. Background Technology

[0002] Chain conveyors, also known as chain conveyor production lines, are commonly used for material transport in factories. Due to fire safety requirements, fire-resistant roller shutters are often installed between factory buildings. If the conveyor line passes directly through the area where these fire-resistant roller shutters are located, the shutters may fail to close properly, and the conveyor line may also be damaged. Therefore, the chain conveyor section for the fire-resistant roller shutters needs to be redesigned to ensure proper closure. Utility Model Content

[0003] The purpose of this utility model application is to improve the problem that the fireproof rolling shutter door cannot close properly due to the presence of a chain conveyor in the area below the fireproof rolling shutter door. This application provides a flip-type chain conveyor.

[0004] The flip-type chain conveyor provided in this application adopts the following technical solution:

[0005] A flip-type chain conveyor, including

[0006] The main conveyor is a chain conveyor;

[0007] The outriggers are flipped and installed below the end of the main conveyor.

[0008] The tilting frame is a frame with conveyor chains on both sides and a tilting cylinder installed at the bottom. The tilting cylinder is mounted on top of the tilting support legs and the tilting frame is located between the chains on both sides of the main conveyor.

[0009] When the tilting frame is set horizontally, the top chain and the top chain of the main conveyor are on the same horizontal plane;

[0010] The drive rod is mounted on the main conveyor, passes through the tilting frame, and is located inside the tilting drum.

[0011] Multiple drive gears are mounted on the drive rod and mesh with the chains on the main conveyor and the tilting frame, respectively. Pressure rollers are installed on both the main conveyor and the tilting frame. The pressure rollers abut against the chains to ensure stable chain engagement.

[0012] The flipping device, installed on the flipping support leg, is used to drive the flipping frame to flip around the central axis of the flipping cylinder.

[0013] Optionally, the drive rod is coaxial with the tilting cylinder.

[0014] Optionally, a first bearing is installed at both ends of the inner wall of the tilting cylinder, and the inner ring of the first bearing is installed on the circumferential outer wall of the drive rod.

[0015] Optionally, second bearings are installed on both sides of the main conveyor, with the inner ring of the second bearings mounted on the circumferential outer wall of both ends of the drive rod.

[0016] Optionally, the tilting cylinder is located on the side of the tilting frame closer to the main conveyor.

[0017] Optionally, the flipping device includes a flipping motor, a first gear, a second gear, and a meshing belt;

[0018] The tilting motor is mounted on the tilting support leg, and a speed reducer is mounted on the tilting support leg. The rotating shaft of the tilting motor is connected to the input end of the speed reducer. The first gear is mounted on the output end of the speed reducer, and the second gear is mounted on the tilting cylinder. The meshing belt meshes with the first gear and the second gear simultaneously and is tightened.

[0019] Optionally, a counterweight is installed at the bottom of the tipping frame near the main conveyor.

[0020] Optionally, a support frame is placed on the side of the tilting outrigger away from the main conveyor. When the tilting frame is in a horizontal state, the end of the tilting frame away from the main conveyor abuts against the support frame.

[0021] Optionally, the tilting device includes a telescopic cylinder, which is rotatably connected to the tilting support leg, and the piston rod end of the telescopic cylinder is rotatably connected to the tilting frame.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The tilting device drives the tilting frame to tilt upward, thereby avoiding the falling point of the fireproof rolling shutter door and allowing the fireproof rolling shutter door to close normally. The position setting of the drive rod and the tilting cylinder can reduce the change in tension of the chain meshed by the drive gear during the tilting frame tilting process, improve the protection effect of the chain, and thus improve the service life of the tilting chain conveyor.

[0024] 2. The coaxial arrangement of the drive rod and the tilting drum ensures that the rotation axis of the tilting frame and the drive axis of the chain are collinear, which can further reduce the change in the chain tension that meshes with the drive gear during the tilting process, further improve the service life of the tilting chain conveyor, and through structures such as pressure rollers, ensure that the chains on the main conveyor and the chains on the tilting frame can stably mesh with the drive gear.

[0025] 3. The rotating motor is used as the power source to drive the rotating cylinder to rotate, which in turn causes the rotating frame to rotate upward, effectively realizing the rotation of the rotating frame. In combination with the counterweight and support frame, it can effectively improve the stability of the rotating frame during the rotation and reset process. Attached Figure Description

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses a flip-type chain conveyor.

[0034] Example 1

[0035] refer to Figure 1 and Figure 2 The tilting chain conveyor includes a main conveyor 1, a tilting frame 2, tilting legs 3, and a tilting device 4. The main conveyor 1 is a chain conveyor. The tilting legs 3 are mounted below the end of the main conveyor 1. The tilting frame 2 is a frame structure with conveyor chains rotating on both sides. A tilting cylinder 21 is installed at the bottom of the tilting frame 2, and the tilting cylinder 21 is rotatably mounted on top of the tilting legs 3. The tilting cylinder 21 is located in the center of the tilting frame 2, close to the main conveyor 1. The tilting frame 2 is situated between the chains on both sides of the main conveyor 1. When the tilting frame 2 is horizontally positioned, the top chain and the top chain of the main conveyor 1 are on the same horizontal plane.

[0036] A drive rod 11 is mounted on the rotating frame of the main conveyor 1. The drive rod 11 passes through the tilting frame 2 and the tilting cylinder 21, and is coaxially arranged with the tilting cylinder 21. First bearings 211 are installed at both ends of the inner wall of the tilting cylinder 21, with their inner rings mounted to the circumferential outer wall of the drive rod 11. Second bearings 111 are installed on both sides of the main conveyor 1, with their inner rings mounted to the circumferential outer walls of the two ends of the drive rod 11. The first bearings 211 are deep groove ball bearings, and the second bearings 111 are bearings with diamond-shaped seats. Multiple drive gears are mounted on the drive rod 11, and these drive gears mesh with the chains on the main conveyor 1 and the tilting frame 2, respectively. Pressure rollers are installed on both the main conveyor 1 and the tilting frame 2, and these pressure rollers abut against the chains to ensure stable chain engagement.

[0037] The tilting device 4 is mounted on the tilting support leg 3 and is used to drive the tilting frame 2 to tilt around the central axis of the tilting cylinder 21. The chain of the main conveyor 1 is driven by the motor of the main conveyor 1 itself, and the chain on the tilting frame 2 is driven by the drive rod 11.

[0038] The tilting frame 2 rotates and tilts around the tilting cylinder 21, while the drive rod 11 is coaxially set with the tilting cylinder 21. This ensures that the tilting frame 2 does not change the position of the drive rod 11 during the tilting process. The drive rod 11, acting as the drive shaft, provides more stable chain drive and reduces changes in chain tension on the main conveyor 1 and the tilting frame 2 during the tilting process. The pressure roller ensures stable engagement of the chains on the main conveyor 1 and the tilting frame 2 with the drive gear after the drive rod 11 is lowered, improving the stability of chain movement. The first bearing 211 effectively reduces friction between the tilting cylinder 21 and the drive rod 11 and improves the stability of the drive rod 11 during rotation. The second bearing 111 further enhances the stability of the drive rod 11's rotation. When the fire door needs to be closed, the tilting device 4 drives the tilting frame 2 upwards to avoid the closing position of the fire door, allowing it to close normally. The tilting frame 2's horizontal position also allows goods on the chain to pass through normally.

[0039] refer to Figure 2 and Figure 3 The flipping device 4 includes a telescopic cylinder 4b, which is rotatably connected to the flipping support leg 3. The piston rod end of the telescopic cylinder 4b is rotatably connected to the flipping frame 2. The extension of the piston rod of the telescopic cylinder 4b causes the flipping frame 2 to flip upwards around the axis of the flipping cylinder 21. The resetting of the piston rod of the telescopic cylinder 4b causes the flipping frame 2 to reset, thus realizing the flipping and resetting functions of the flipping frame 2.

[0040] Example 2

[0041] The difference between Embodiment 2 and Embodiment 1 of this application is as follows:

[0042] refer to Figure 4 and Figure 5 The tilting device 4 includes a tilting motor 4a1, a first gear 4a2, a second gear 4a3, and a meshing belt 4a4. The tilting motor 4a1 is mounted on the tilting support leg 3, and a reducer 4a11 is mounted on the tilting support leg 3. The rotating shaft of the tilting motor 4a1 is connected to the input end of the reducer 4a11. The first gear 4a2 is mounted on the output end of the reducer 4a11, and the second gear 4a3 is mounted on the tilting cylinder 21. The meshing belt 4a4 meshes with and is tightened with both the first gear 4a2 and the second gear 4a3. A counterweight 22 is installed at the bottom of the tilting frame 2 near the main conveyor 1, which brings the center of gravity of the entire tilting frame 2 closer to the tilting cylinder 21, thereby reducing the torsional load at the tilting cylinder 21. A support frame 5 is placed on the side of the tilting support leg 3 away from the main conveyor 1. When the tilting frame 2 is in a horizontal state, the end of the tilting frame 2 away from the main conveyor abuts against the support frame 5, thereby providing support for the horizontally positioned tilting frame 2 and improving the stability of the tilting frame 2 during normal cargo transportation.

[0043] In this embodiment, the flipping mechanism 2 is driven by a flipping motor 4a1, which drives the second gear 4a3 and the flipping cylinder 21 to rotate together via a meshing belt 4a4, thereby causing the flipping mechanism 2 to flip relative to the flipping support leg 3. Compared with the method in embodiment 1, this driving method can effectively improve the protection of the flipping cylinder 21, making the flipping mechanism 2 more stable and extending its overall service life.

[0044] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
