Description

Technical Field

[0001] This invention relates to the field of axle production technology, and in particular to an axle production conveyor line and conveying method. Background Technology

[0002] During the production process, axles need to be processed on different equipment, and they are transported between different processing equipment via conveyor lines to achieve processing and production.

[0003] The transfer trolley can replace the traditional overhead crane hoisting solution, improving the efficiency of axle transfer and expanding the application scenarios. Traditional axle production conveyor lines use a lifting structure inside the transfer trolley to elevate the gripped axle, separating it from the conveying device for normal axle transfer. However, installing the lifting device inside the transfer trolley occupies space from other internal equipment, resulting in a larger overall weight and size, hindering rapid axle transfer. Furthermore, lifting the entire system, especially when carrying the axle at the end, reduces the stability of the transfer trolley and the axle above it, raising the center of gravity and compromising overall stability. Traditional production conveying methods affect the stability of axle transport, limiting its efficiency and safety. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides an axle production conveyor line and conveying method. This invention can stably support, transfer, and convey axles, improving the safety and efficiency of axle conveying.

[0005] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0006] A vehicle axle production conveyor line includes two parallel axle conveying devices and an axle transfer device located on one side of the two axle conveying devices. The axle transfer device has a first telescopic device and a second telescopic device installed on its upper end. A drive device is installed on the surface of the axle transfer device to control the movement of the first telescopic device and the second telescopic device. A load-bearing component is installed on the surface of the second telescopic device. A guide support plate is installed on the side wall of the first telescopic device. A lifting device adapted to the load-bearing component is installed on the surface of the axle conveying device. A guide component adapted to the guide support plate is installed on the inner wall of the upper end of the axle conveying device.

[0007] Preferably, the axle conveying device includes a conveying base and belt conveyors installed on both sides of the conveying base. A first bearing base is fixedly connected to the conveying surface of the belt conveyor. The upper end of the first bearing base has a groove that matches the surface of the axle. The horizontal height of the top of the first bearing base is lower than the horizontal height of the bottom of the bearing component.

[0008] Preferably, the lifting device includes a lifting bearing plate installed on the outside of the belt conveyor, a second bearing base adapted to the axle surface is fixedly provided at the upper end of the lifting bearing plate, and a lifting telescopic device is installed at the bottom of the lifting bearing plate.

[0009] Preferably, the guide components are configured in two sets, and the two sets of guide components are symmetrically arranged inside the belt conveyor. The sidewall of the guide component has a strip guide groove that matches the guide support plate.

[0010] Preferably, the axle transfer device includes a transfer body, the top of which is recessed to form a bearing area for accommodating a first telescopic device and a second telescopic device, a traveling wheel is installed on the side wall of the transfer body, and a traveling motor is installed on the surface of the transfer body to control the rotation of the traveling wheel.

[0011] Preferably, a locking component is fixedly provided on the outer sidewall of the axle transfer device, the inner wall of the locking component is recessed to form a locking groove, and a locking strip adapted to the locking groove is installed on the travel path of the axle transfer device.

[0012] Preferably, the upper surface of the bearing component has a limiting groove, and the inner walls on both sides of the limiting groove are inclined limiting slopes. During the longitudinal extension and retraction of the first telescopic device and the second telescopic device, the limiting groove longitudinally limits the axle.

[0013] Preferably, a hydraulic lifting element is fixedly connected to the surface of the guide support plate. After the first telescopic device and the second telescopic device overlap, the hydraulic lifting element is positioned opposite to the limiting groove. A hydraulic control element connected to the hydraulic lifting element is fixed at the top of the axle transfer device. The hydraulic control element is located on the moving path of the first telescopic device.

[0014] Preferably, the first telescopic device includes two bearing rails with an I-shaped cross-section, the second telescopic device is installed between the two bearing rails, and a first guide slide is fixed to the outer wall of the first telescopic device, and a second guide slide adapted to the bearing rail is installed on the top of the axle transfer device.

[0015] A method for conveying axles during production includes the following steps:

[0016] S1. Control the axle transfer device to move to a predetermined position on one side of the first axle conveying device. After the lifting device completes the lifting of the axle, control the first telescopic device and the second telescopic device to extend. After the second telescopic device moves to the predetermined position, control the lifting device to descend to complete the loading of the axle.

[0017] S2. After the axle loading is completed in step S1, control the first telescopic device and the second telescopic device to return to their initial positions, and then control the axle transfer device to move towards the direction of the second axle conveying device to complete the axle unloading.

[0018] The beneficial effects of this invention are as follows:

[0019] Compared to the traditional method of controlling the lifting and lowering of the top of the axle transfer device, by installing a lifting device on the side of the axle conveying device close to the axle transfer device, the axle can be lifted before the second telescopic device extends (500°), thus providing lifting support for the axle. After the second telescopic device extends to the predetermined position, it captures and supports the axle, achieving continuous axle transfer. This solution eliminates the need to control the upward lifting of the extended second telescopic device, ensuring that the overall structural center is in a low and stable position, guaranteeing the continuity and stability of axle transfer, improving the efficiency and stability of axle transfer, and ensuring the safety of axle production. Simultaneously, by setting up a guide component in conjunction with a guide support plate, the extended first telescopic device can be supported from the bottom, further ensuring the stability of the first and second telescopic devices during axle transfer.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] See attached document Figure 1 - Appendix Figure 9 A type of axle production conveyor line includes two parallel axle conveying devices 100 and an axle transfer device 200 located on one side of the two axle conveying devices 100. A first telescopic device 500 and a second telescopic device 600 are mounted on the upper end of the axle transfer device 200. A drive device 240 is mounted on the surface of the axle transfer device 200 to control the telescopic movement of the first telescopic device 500 and the second telescopic device 600. Axles requiring forging are directionally conveyed on the surface of the axle conveying devices 100 for continuous processing. The first axle conveying device 100 directionally conveys the axle towards the axle transfer device 200. The axle at the end of the first axle conveying device 100 is then conveyed to one side of the second axle conveying device 100, completing the axle transfer. The axle then moves directionally away from the axle transfer device 200 on the surface of the second axle conveying device 100, completing the continuous processing of the axle. This design can replace the traditional method of hoisting axles using a crane, resulting in high axle transfer efficiency and good transfer stability.

[0032] The second telescopic device 600 has a bearing component 610 mounted on its surface, and the first telescopic device 500 has a guide support plate 530 mounted on its side wall. The axle conveying device 100 has a lifting device 300 adapted to the bearing component 610 mounted on its surface, and a guide component 400 adapted to the guide support plate 530 mounted on the upper inner wall of the axle conveying device 100. The axle is carried and conveyed on the surface of the bearing component 610. Before the axle transfer device 200 moves towards the first axle conveying device 100 to grab it, the lifting device 300 lifts the axle on the surface of the axle conveying device 100, so that the axle is located at a predetermined position above the axle conveying device 100. Then, the first telescopic device 500 and the second telescopic device 600 are controlled to extend and pass under the axle, so that the bearing component 610 is located at a predetermined position under the axle. Then, the lifting device 300 is controlled to drive the axle to descend. At this time, the axle alternates from the surface of the lifting device 300 to the surface of the bearing component 610 for bearing and limiting, thus completing the transfer of the axle load.

[0033] Through the above structural design, the built-in lifting device of the axle transfer device 200 is eliminated. Instead, a lifting device 300 is installed on the side of the axle conveying device 100 near the axle transfer device 200 to lift the axle. This reduces the internal component structure of the axle transfer device 200, and the lightweight design of the axle transfer device 200 reduces its energy consumption during the transfer process. At the same time, during the axle gripping process, the axle transfer device 200 does not need to be lifted to a higher position. As the axle transfer device 200 extends to grip the axle, the center of gravity of the entire device is closer to the ground, ensuring the stability of the overall structure during the axle gripping process.

[0034] By setting a double-layer telescopic structure with a first telescopic device 500 and a second telescopic device 600, a greater telescopic length can be achieved, enabling the grabbing of axles at a distance and the sequential grabbing of multiple axles. Furthermore, by setting a guide support plate 530 and a guide assembly 400 between the axle conveying device 100 and the axle transfer device 200, the extended first telescopic device 500 can be limited from both sides after the first telescopic device 500 and the second telescopic device 600 extend, and the first telescopic device 500 can be supported from both sides, ensuring the stability of the overall structure, further ensuring the stability of the axles during movement, increasing the number of axles grabbed at one time, and ensuring the safety of axle production and transportation.

[0035] The axle conveying device 100 includes a conveying base and belt conveyors 110 mounted on both sides of the conveying base. A first bearing base 120 is fixedly connected to the conveying surface of the belt conveyor 110. The upper end of the first bearing base 120 has a groove adapted to the surface of the axle. The horizontal height of the top of the first bearing base 120 is lower than the horizontal height of the bottom of the bearing assembly 610. The belt conveyors 110 on both sides move synchronously, and can drive the axle to move synchronously towards the axle transfer device 200 through the first bearing base 120 with its surface opposite to it, thus completing the synchronous conveying of the axle. Through the above structural design, the axle can be carried and conveyed from both sides, ensuring the stability of the axle conveying on the surface of the axle conveying device 100. Simultaneously, it can form an area at the bottom of the axle for the chassis of the first telescopic device 500 and the second telescopic device 600 to pass through, ensuring that the overall structure can normally grasp the axle; at the same time, the top height of the first bearing base 120 is relatively low. After the bearing component 610 supports the axle, the bottom of the axle is higher than the top of the first bearing base 120. There is no need to adjust the height of the axle conveying device 100 and the axle transfer device 200. The first telescopic device 500 and the second telescopic device 600 can retract and reset along the initial movement path without interfering with the equipment on the surface of the axle conveying device 100, realizing rapid overall retraction and ensuring the stability of the surface axle during the retraction process.

[0036] Please refer to the appendix for details. Figure 5 The lifting device 300 includes a lifting support plate 310 installed on the outside of the belt conveyor 110. A second support base 330 adapted to the surface of the axle is fixedly installed on the upper end of the lifting support plate 310. A lifting telescopic device 320 is installed at the bottom of the lifting support plate 310. The lifting telescopic device 320 is preferably a hydraulic lifting device, which can lift the upper lifting support plate 310 and the lifting device 300 from the bottom, control the overall structure to move towards the axle direction on the surface of the axle conveyor 100, and control the axle to lift to a predetermined height so that the second telescopic device 600 can pass under the axle to alternately support the axle. Through the above structural design, the axle can be supported from both sides, ensuring the stability of the axle. At the same time, the overall structure is designed to withstand high temperatures, and can support the axle in a high-temperature forging state. The overall equipment has a wide range of applications.

[0037] The first bearing base 120 and the second bearing base 330 mentioned above can be set in multiple intervals. The bearing component 610 can simultaneously transfer at least two axles, which increases the number of axles transferred by the axle transfer device 200 at one time, improves the efficiency of axle transfer and transportation, and shortens the in-transit transportation time of axle processing.

[0038] Specifically, the guide components 400 are configured in two sets, and the two sets of guide components 400 are symmetrically arranged inside the belt conveyor 110. The side wall of the guide component 400 has a strip-shaped guide groove 410 adapted to the guide support plate 530. During the extension of the first telescopic device 500 and the second telescopic device 600, the horizontal height of the guide support plate 530 is opposite to the position of the strip-shaped guide groove 410. The guide support plate 530 can extend into the strip-shaped guide groove 410, and the strip-shaped guide groove 410 supports the guide support plates 530 on both sides of the first telescopic device 500 to ensure the stability of the overall structure. At the same time, guide balls can be installed at the bottom of the inner wall of the strip-shaped guide groove 410 to reduce the friction of the guide support plate 530 during the movement, reduce the wear of the overall equipment, reduce the resistance after gripping the axle, and improve the efficiency of the axle in the telescopic gripping process.

[0039] Specifically, the axle transfer device 200 includes a transfer body 210. The top of the transfer body 210 is recessed to form a bearing area 211 for accommodating the first telescopic device 500 and the second telescopic device 600. The side wall of the transfer body 210 is equipped with a traveling wheel 220, and a traveling motor 221 is installed on the surface of the transfer body 210 to control the rotation of the traveling wheel 220. A traveling rail is installed at the bottom of the traveling wheel 220. At least two sets of traveling wheels 220 are symmetrically arranged to ensure the stability of the overall structure moving on the surface of the traveling rail. At the same time, the first telescopic device 500 and the second telescopic device 600 are embedded in the design. After the overall structure is contracted, the axle is located in the middle position of the axle transfer device 200. The center of gravity of the axle and the overall equipment is located in the middle position, which further ensures the smoothness of the axle transfer device 200 when moving between the two axle conveying devices 100.

[0040] A locking component 230 is fixedly installed on the outer sidewall of the axle transfer device 200. The inner wall of the locking component 230 is recessed to form a locking groove 231. A locking strip that matches the locking groove 231 is installed on the travel path of the axle transfer device 200. The locking component 230 is located on the side away from the axle conveying device 100, and can lock the axle transfer device 200 and the axle at the upper end of the axle transfer device 200 from the outside. Especially when the first telescopic device 500 and the second telescopic device 600 are extended, the locking groove 231 of the locking component 230 can cooperate with the internal locking strip to lock, ensuring that the overall structure of the axle transfer device 200 can be anchored to the bottom travel rail surface without tilting or deflection. This improves the mass of the axle carried by the second telescopic device 600 in a single operation and ensures that the second telescopic device 600 extends a greater distance, thus improving the axle gripping effect.

[0041] Please refer to the appendix for details. Figure 8A limiting groove 611 is formed on the upper surface of the bearing component 610. The inner walls on both sides of the limiting groove 611 are inclined limiting slopes. During the longitudinal extension and retraction of the first telescopic device 500 and the second telescopic device 600, the limiting groove 611 longitudinally limits the axle. Here, longitudinal refers to the direction of extension and retraction of the first telescopic device 500 and the second telescopic device 600. The inclined design of the limiting groove 611 on both sides can adapt to the bearing of axles of different sizes. At the same time, the inclined limiting groove 611 on both sides can limit the axle from both longitudinal sides, ensuring the longitudinal stability of the axle transport during the extension and retraction of the first telescopic device 500 and the second telescopic device 600.

[0042] Please refer to the appendix for details. Figure 9 A hydraulic lifting element 520 is fixedly connected to the surface of the guide support plate 530. After the first telescopic device 500 and the second telescopic device 600 overlap, the hydraulic lifting element 520 is positioned opposite to the limiting groove 611. A hydraulic control element 250 connected to the hydraulic lifting element 520 is fixed at the top of the axle transfer device 200. The hydraulic control element 250 is located on the moving path of the first telescopic device 500.

[0043] The hydraulic lifting element 520 can be configured as two sets or as one set. One set of hydraulic lifting elements 520 is located behind the moving axle transfer device 200, and can lift and support the axle from the bottom side to overcome the inertia of the axle deflection during the sudden start of the axle transfer device 200. It can support the axle laterally and ensure the lateral stability of the axle. At the same time, the hydraulic lifting element 520 automatically extends after the first telescopic device 500 and the second telescopic device 600 overlap. During the reset and movement of the first telescopic device 500, it will squeeze the hydraulic control element 250 to control its contraction, and squeeze the control oil in the hydraulic control element 250 into the hydraulic lifting element 520 to control its lifting. A delayed pumping component can be set in the connected pipeline to control the delayed pumping of the oil to ensure that the axle is lifted after it is stable. Alternatively, a double-layer lifting support plate can be installed at the telescopic end of the hydraulic lifting element 520 to achieve lifting support for the axle during the movement.

[0044] The aforementioned first telescopic device 500 includes two bearing rails 510, each bearing rail 510 having an I-shaped cross-section. The second telescopic device 600 is installed between the two bearing rails 510, and a first guide slide block 620 is fixed to the outer wall of the first telescopic device 500. A second guide slide block adapted to the bearing rails 510 is installed on the top of the axle transfer device 200. The bearing rails 510 are positioned between the second telescopic device 600 and the axle transfer device 200, providing support and guidance to ensure the stability of the overall structure's movement. Both the first guide slide block 620 and the second guide slide block include a first roller arranged laterally and a second roller arranged horizontally, ensuring the stability of the first telescopic device 500 and the second telescopic device 600 during the extension process.

[0045] A method for conveying axles during production includes the following steps:

[0046] S1. Control the axle transfer device 200 to move to a predetermined position on one side of the first axle conveying device 100. After the lifting device 300 completes the lifting of the axle, control the first telescopic device 500 and the second telescopic device 600 to extend. After the second telescopic device 600 moves to the predetermined position, control the lifting device 300 to descend to complete the loading of the axle. Through the above structural design, it is not necessary to control the lifting of the first telescopic device 500 and the second telescopic device 600, which ensures that the overall center of gravity of the axle transfer device 200 is in a low and stable position, and ensures the stability of the axle transfer between the axle conveying device 100 and the axle transfer device 200.

[0047] S2. After the axle loading is completed in step S1, control the first telescopic device 500 and the second telescopic device 600 to return to their initial positions. Then, control the axle transfer device 200 to move towards the second axle conveying device 100 to complete the axle unloading. The axle unloading process is the same as the loading process. The guide component 400 can support the extended first telescopic device 500, ensuring that the bottom structure can be supported after the first telescopic device 500 and the second telescopic device 600 are extended, thus ensuring the stability of the overall structure. (Refer to Appendix) Figure 2 The upper one is the second axle conveyor 100, and the lower one is the first axle conveyor 100.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
