Description

Technical Field

[0001] The utility model relates to the technical field of conveying devices, in particular to a transportation turntable and a production line. Background Art

[0002] In the glass melting and rolling production process, the machines at the production stations are placed on vertical tracks, and the standby machines are horizontally parked on the side tracks. Therefore, when the on-line machine on the vertical track fails, the on-line machine needs to be withdrawn, and then the standby machine is transported along the track to the production station. The function of the turning transportation platform is to change the transportation direction of the standby machine.

[0003] The existing turning transportation platforms mainly include two types. One is the non-powered turning transportation platform, which mainly consists of a base frame, a support wheel system, a rotating bearing mechanism, a rotating frame, and a guide rail. After the equipment runs to the predetermined position of the platform, it is necessary to manually push the platform to rotate 90 degrees to change the movement direction of the equipment. The other is the internal-powered turning transportation platform, which is based on the structure of the original non-powered platform. A ring gear is installed outside the internal rotating bearing, and then it is driven by an internal speed reducer to enable the platform to have the function of automatic rotation.

[0004] The above turning transportation platforms have the following defects: 1. The design and installation position of the speed reducer is concealed, the space is narrow and difficult to install, adjust, maintain, and repair; 2. The speed reducer is externally meshed with the ring gear. If the speed reducer fails, the rotation direction of the platform is locked and difficult to rotate; 3. The speed reducer drives the rotation of the rotating frame and the machine equipment, and a large torque needs to be output, resulting in easy damage to the speed reducer; 4. The top guide rail is higher than the upper surface of the equipment, and the transported machine is prone to jolting; 5. The overall equipment is located in a humid environment, and the motor and circuits are easily immersed in water and cause short-circuit faults.

[0005] Therefore, there is an urgent need to provide a new type of transportation turntable and production line to solve the above technical problems in the prior art. Summary of the Utility Model

[0033] Please refer to Figures 1 to 3 , in this embodiment, the transportation turntable includes a support platform 100, a rotating platform 200, and a driving device 300. The above-mentioned rotating platform 200 is arranged above the above-mentioned support platform 100, and the above-mentioned rotating platform 200 can rotate around its own central axis on the above-mentioned support platform 100. A conveying guide rail 201 for transporting articles is arranged on the top wall of the above-mentioned rotating platform 200, and a driving gear ring 202 is arranged around the circumference of the above-mentioned rotating platform 200; a driving gear 301 meshing with the above-mentioned driving gear ring 202 is arranged at the output end of the above-mentioned driving device 300, and the above-mentioned driving device 300 is used to drive the above-mentioned rotating platform 200 to rotate around its own central axis.

[0034] The transport turntable in this embodiment uses a support platform 100 to support a rotating rotating platform 200. The top wall of the rotating platform 200 is provided with a conveying guide rail 201, so that the conveying guide rail 201 can be used to rotate and transport items. When the rotating platform 200 rotates around its own central axis, the drive gear 301 provided at the output end of the drive device 300 engages with the drive ring gear 202 arranged around the rotating platform 200. Under the drive of the drive device 300, the drive gear 301 drives the drive ring gear 202 to rotate, thereby driving the rotating platform 200 to rotate around its own central axis on the support platform 100, thereby transporting items on the conveying track from one direction to another. The transport turntable has a simple structure, is easy to install and maintain, has a longer service life, and transports items more smoothly, reducing the incidence of malfunctions of the transported items.

[0035] like Figure 3 As shown, a plurality of support rollers 110 are fixedly mounted on either the top wall of the support platform 100 or the bottom wall of the rotating platform 200 at intervals along the circumferential direction, with the other supporting roller abutting against the rim of the support roller 110. The support rollers 110 are used to support the rotating platform 200 as it rotates. The rotation of the support rollers 110 stabilizes the movement of the rotating platform 200, ensuring smooth rotation of the rotating platform 200, reducing jolting and jamming of the rotating platform 200, and ensuring that items are smoothly diverted and transported.

[0036] Optionally, the support roller 110 includes a base 111 and a wheel body 112. The base 111 is disposed on the top wall of the support platform 100. The wheel body 112 is rotatably connected to the base 111, and the wheel body 112 abuts against the bottom wall of the rotating platform 200. The base 111 is used to support the wheel body 112, ensuring that the wheel body 112 can rotate smoothly, while improving the stability of the rotation of the wheel body 112, and further ensuring that the items are smoothly turned and transported.

[0037] In this embodiment, the support rollers 110 are distributed on the support platform 100 at equal intervals along the circumferential direction, so that the supporting force is more uniform.

[0038] As a preferred embodiment, the output end of the drive device 300 is provided with a reducer 302, which is connected to the drive gear 301. The reducer 302 is used to change the output speed of the drive device 300, such as the drive motor, thereby changing the output torque, the rotation speed and load capacity of the rotating platform 200, and is suitable for transporting items of different weights, while also increasing the service life of the drive device 300.

[0039] Further, if Figure 3 and Figure 4As shown in the figure, the above-mentioned speed reducer 302 is connected to a clutch 303, the above-mentioned clutch 303 is connected to the above-mentioned driving gear 301, and the above-mentioned clutch 303 is used to drive the above-mentioned driving gear 301 to engage or disengage with the above-mentioned driving gear ring 202. The setting of the clutch 303 enables the engagement between the driving gear ring 202 and the driving gear 301 to be disengaged when the driving device 300 fails, so that the rotating platform 200 can be manually rotated to rotate the article and change the transportation direction.

[0040] Please continue to refer to Figure 3 , the top wall of the above-mentioned conveying guide rail 201 is not higher than the top wall of the above-mentioned rotating platform 200. Such a setting enables the top wall of the rotating platform 200 to provide a certain support for the article when the conveying guide rail 201 conveys the article, avoiding the article from tipping over and improving the stability of transportation.

[0041] Optionally, a walking platform 210 is provided on the top wall of the above-mentioned rotating platform 200, an avoidance groove 211 is formed on the walking platform 210, and the above-mentioned conveying guide rail 201 is arranged in the avoidance groove 211. The walking platform 210 provides support for the article when the article is rotated, and the setting of the avoidance groove 211 can realize the structure that the conveying guide rail 201 is not higher than the rotating platform 200, and at the same time avoid the conveying guide rail 201 to ensure that there is no interference between various structures and components.

[0042] Furthermore, there is a gap with a preset distance between the side wall of the above-mentioned conveying guide rail 201 and the side wall of the avoidance groove 211. The gap with the preset distance can ensure that when the conveying track conveys the article, it provides a safe space for the bottom of the article, such as rollers, pulleys, etc., to ensure that the article is smoothly transported.

[0043] It should be noted that the above-mentioned driving device 300 is installed on a fixed seat 304, and the fixed seat 304 is fixed to the ground so that there is a preset height of ground clearance between the driving device 300 and the ground. The setting of the base 111 raises the driving device 300 by a certain height, so that there is a preset height of ground clearance between the driving device 300 and the ground, thereby avoiding the driving device 300 and the wires in the driving device 300 from getting wet and avoiding the occurrence of short-circuit faults.

[0044] Another object of the present invention is to provide a production line, which includes the transportation turntable described in any of the above solutions.

[0045] The production line provided according to the technical solution of the present invention includes one or more transportation turntables described in any of the above solutions. Since the production line includes one or more transportation turntables described in any of the above solutions, therefore, the production line has all the beneficial effects of the transportation turntable described in any of the above solutions.

[0046] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all implementation manners here.
