Abstract
Description
Technical Field
[0001] This utility model relates to the field of mobile ceiling track technology, specifically a heavy-duty robotic ceiling track. Background Technology
[0002] Robotic overhead tracks are an automated solution that mounts industrial robots on high-precision tracks. By freeing robots from traditional ground-mounted positions, they allow them to move freely along pre-defined paths in two- or three-dimensional space, significantly expanding the working range of a single robot. The system typically consists of core components such as high-strength aluminum alloy tracks, intelligent mobile servo vehicles, the robot itself, a central control system, and safety protection devices. Its core advantage lies in significantly improving space utilization, making it particularly suitable for modern flexible production lines with limited space or requiring long-distance, multi-station operations. It is commonly found in complex processes such as painting, assembly, inspection, and material handling in the automotive and aerospace industries. Robotic overhead tracks not only achieve a high degree of automation and flexibility in production processes, reducing interference from ground equipment and optimizing the human-robot collaboration environment, but also effectively improve production efficiency and overall system reliability through precise repetitive positioning and efficient task scheduling. It is an indispensable key infrastructure for logistics and manufacturing in modern smart factories.
[0003] Some robot overhead rails rely on motors, gears, and racks for motion. When a stop is needed, the motors stop or rotate in reverse to shorten the stopping time. The engagement of the gears and racks counteracts the robot's inertia. For robots with heavy loads, the inertial kinetic energy is large, and the wear rate of the gears and racks is accelerated. Replacing the gears and racks is difficult and costly. Utility Model Content
[0004] To address the aforementioned issues, this application provides a heavy-duty robot overhead track that solves the problems of a single braking method and rapid wear of gears and racks.
[0005] A heavy-duty robot overhead track includes a support frame, two slide rails are symmetrically fixedly installed on the top of the support frame, and a movable base is slidably engaged on the outer side of the slide rails. A brake caliper for auxiliary braking is movably installed on the outer side of the movable base, and a hydraulic cylinder for driving it to conform to the slide rail is installed on the outer side of the brake caliper. The outside of the mobile base is also equipped with a vertically mounted brake column, and the top of the slide rail is provided with multiple casting holes. In case of emergency braking, the hydraulic cylinder drives the brake column to move down and insert into the casting holes.
[0006] Furthermore, a robotic arm is mounted on top of the mobile base.
[0007] Furthermore, a motor is fixedly installed on the top of the movable base, a gear is fixedly installed on the output end of the motor, a rack is meshed on the outside of the gear, and the rack is fixedly installed on the top of the support frame.
[0008] Furthermore, a climbing ladder is installed on the outside of the mobile base.
[0009] Furthermore, the hydraulic cylinder is fixedly installed on the outside of the movable base, and a compression spring is fixedly installed between the outside of the hydraulic cylinder's telescopic end and the outside of the brake caliper.
[0010] Furthermore, an installation chamber is fixedly installed on the outside of the movable base, a brake column is slidably installed on the inside of the installation chamber, a storage spring is fixedly installed between the top of the brake column and the inside of the installation chamber, a lever is fixedly installed on the top of the storage spring, and the lever slides through the top of the installation chamber.
[0011] Furthermore, ball heads are provided at the top of the lever and at the end of the cylinder extension / retraction.
[0012] Furthermore, multiple elastic ropes are fixedly installed between the top of the brake column and the inside of the mounting chamber.
[0013] The beneficial effects of this utility model are as follows: The heavy-duty robot overhead track described in this utility model is equipped with a brake caliper. When the robot arm reaches the work position, the motor stops rotating, the extension end of the hydraulic cylinder extends, the compression spring is compressed, and the brake caliper moves to fit the slide rail. The auxiliary gears and racks brake, reducing the wear rate of the gears and racks. It is also equipped with a brake column. In case of emergency, such as when the motor loses power or the moving base moves too fast, the extension end of the hydraulic cylinder extends and the extension length increases. This causes the extension end of the hydraulic cylinder to press against the lever rod, causing the lever rod to move downward. The brake column moves down and presses against the slide rail. When the brake column moves to the casting hole, the elastic force of the storage spring causes the brake column to move down and enter the casting hole, achieving rigid blocking braking and preventing the moving base, robotic arm and other heavy loads from derailing.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.
[0018] To keep the drawings concise, each figure only schematically shows the parts relevant to the utility model, and these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0019] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0021] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance. First embodiment: like Figure 1 , Figure 2 As shown, this utility model embodiment provides a heavy-duty robot overhead track, including a support frame 1. Two slide rails 7 are symmetrically fixedly installed on the upper part of the support frame 1. A movable base 3 is slidably connected to the outer side of the slide rails 7. A robotic arm 4 for processing is installed on the top of the movable base 3. A climbing ladder 2 is installed on the outer side of the movable base 3 to facilitate the maintenance and repair of the robotic arm 4 by the staff.
[0023] Furthermore, such as Figure 2 As shown, a motor 10 is fixedly installed on the top of the movable base 3, a gear 5 is fixedly installed on the output end of the motor 10, a rack 6 is meshed on the outside of the gear 5, and the rack 6 is fixedly installed on the top of the support frame 1.
[0024] Furthermore, such as Figure 3 , Figure 4 As shown, a brake caliper 12 for auxiliary braking is movably installed on the outside of the movable base 3 to reduce the frictional wear of the gear 5 and rack 6 and extend their service life. A hydraulic cylinder 9 for driving the brake caliper 12 to engage with the slide rail 7 is installed on the outside of the brake caliper 12.
[0025] In this embodiment, when the robot arm 4 is working, the motor 10 starts, driving the gear 5 to rotate. Under the action of the rack 6, the moving base 3 and the robot arm 4 move. When they reach the work station, the motor 10 stops rotating, the extension end of the hydraulic cylinder 9 extends, the compression spring 11 is compressed, and the brake caliper 12 moves to fit against the slide rail 7, assisting the gear 5 and rack 6 to brake, reducing the wear rate of the gear 5 and rack 6. Before the moving base 3 moves again, the extension end of the hydraulic cylinder 9 shortens, driving the compression spring 11 and brake caliper 12 to reset.
[0026] Second embodiment: The difference from the above embodiments is that, as Figure 3 , Figure 5 As shown, a vertically mounted brake column 16 is also installed on the outside of the movable base 3, and multiple casting holes 8 are provided on the top of the slide rail 7. During emergency braking, the hydraulic cylinder 9 drives the brake column 16 to move down and insert into the casting holes 8.
[0027] Furthermore, such as Figure 4 As shown, the hydraulic cylinder 9 is fixedly installed on the outside of the movable base 3, and a compression spring 11 is fixedly installed between the outside of the extension end of the hydraulic cylinder 9 and the outside of the brake caliper 12, which is used to drive the brake caliper 12 to reset.
[0028] Furthermore, such as Figure 5 As shown, an installation chamber 13 is fixedly installed on the outside of the movable base 3, a brake column 16 is slidably installed on the inside of the installation chamber 13, a storage spring 15 is fixedly installed between the top of the brake column 16 and the inside of the installation chamber 13, a lever 14 is fixedly installed on the top of the storage spring 15, and the lever 14 slides through the top of the installation chamber 13.
[0029] Furthermore, such as Figure 3 , Figure 5 As shown, multiple elastic ropes 17 are fixedly installed between the top of the brake column 16 and the inner side of the mounting chamber 13, which are used to drive the brake column 16 to suspend above the slide rail 7. During normal operation, the brake column 16 does not contact the slide rail 7.
[0030] In this embodiment, in the event of an emergency, such as a power outage of the motor 10 or an excessively high moving speed of the movable base 3, the control unit sends an electrical signal to the hydraulic cylinder 9. The extension end of the hydraulic cylinder 9 extends and its extension length increases, causing the extension end of the hydraulic cylinder 9 to press against the lever 14, causing the lever 14 to move downward. The energy storage spring 15 is compressed, the elastic rope 17 is stretched, and the brake pin 16 moves down to press against the slide rail 7. When the brake pin 16 moves to the casting hole 8, the elastic force of the energy storage spring 15 causes the brake pin 16 to move down into the casting hole 8, achieving rigid braking and preventing the movable base 3, the robotic arm 4, and other heavy loads from derailing.
[0031] Furthermore, such as Figure 4 , Figure 5 As shown, ball heads are provided at the top of the lever 14 and the telescopic end of the cylinder 9, so that the telescopic end of the cylinder 9 can press the top of the lever 14.
[0032] Specific working methods: When the robotic arm 4 is working, the motor 10 starts and drives the gear 5 to rotate. Under the action of the rack 6, the base 3 and the robotic arm 4 move. When they reach the work position, the motor 10 stops rotating, the extension end of the hydraulic cylinder 9 extends, the compression spring 11 is compressed, and the brake caliper 12 moves to fit the slide rail 7. The auxiliary gear 5 and rack 6 brake, reducing the wear rate of the gear 5 and rack 6. Before the subsequent moving base 3 moves again, the extension end of the hydraulic cylinder 9 shortens, causing the compression spring 11 and brake caliper 12 to reset.
[0033] In case of an emergency, such as a power outage of motor 10 or excessive speed of moving base 3, the control unit sends an electrical signal to cylinder 9. The extension end of cylinder 9 extends and the extension length increases, causing the extension end of cylinder 9 to press against lever 14, causing lever 14 to move downward. The storage spring 15 is compressed and the elastic rope 17 is stretched. The brake pin 16 moves down and presses against slide rail 7. When the brake pin 16 moves to casting hole 8, the elastic force of storage spring 15 causes the brake pin 16 to move down and enter casting hole 8, achieving rigid braking and preventing heavy loads such as moving base 3 and robotic arm 4 from derailing.
[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
