Description

Technical Field

[0001] This utility model relates to the field of track trolleys, and in particular to arc-shaped tracks and trolleys. Background Technology

[0002] In recent years, the combination of curved tracks and multimedia technology has led to innovative products such as curved track screens with upper and lower matrix displays. This type of equipment, through its mechanical rotation design, allows the screen to form a graceful arc during opening and closing, providing viewers with a completely new audiovisual experience. It is widely used in advertising displays, artistic performances, and other occasions. Standard high-precision curved tracks are mostly used in curved conveyor lines and assembly lines in the 3C non-standard automation industry. These tracks have a small radius, low load capacity, and low requirements for the transmission of strong and weak current on the rotating worktable. Ordinary heavy-duty hoisting curved tracks use standard steel bent into a circle, such as I-beams or H-beams, and are moved using a circular trolley or electric hoist. This results in poor motion precision control and low requirements for the transmission of strong and weak current on the rotating worktable.

[0003] Given the above background, there is currently no solution in the technology that can simultaneously meet the requirements of high load and high motion precision control; long-distance + arc motion presents the problem of wired power supply for both high and low voltage, and there is no solution; currently, there are no standardized products on the market that meet the above two points.

The trolley body also includes an opening through the bottom of the ceiling decorative surface. The trolley body is slidably connected to the arc-shaped track. An arc-shaped cable follower mechanism that is connected to the trolley body is also fixedly installed on the outside of the support bracket.

[0006] Preferably, the trolley body includes a load-bearing and guide wheel assembly that is slidably mounted on the arc track, and a drive motor is fixedly installed at the bottom of the trolley body.

[0007] Preferably, the drive motor power end is movably connected to a gear after passing through the trolley body, and the bottom of the arc track is fixedly connected to an arc-shaped rack meshing with the gear.

[0019] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within 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.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-3 The system includes an arc-shaped track and trolley, comprising a support bracket 2 connected to the top of the building, an arc-shaped track 3 fixedly installed at the bottom of the support bracket 2, the arc-shaped track 3 being located at the upper end of the ceiling decorative surface 1, and a trolley body 5. An opening 4 is provided through the bottom of the ceiling decorative surface 1. The trolley body 5 is slidably connected to the arc-shaped track 3. An arc-shaped cable follower mechanism 6, which is connected to the trolley body 5, is also fixedly installed on the outside of the support bracket 2. The trolley body 5 includes a support and guide wheel assembly 51 that is slidably installed on the arc-shaped track 3. A drive motor 52 is fixedly installed at the bottom of the trolley body 5. The power end of the drive motor 52 moves through the trolley body 5 and is fixedly connected to a gear 53. An arc-shaped rack 31 that meshes with the gear 53 is fixedly connected to the bottom of the arc-shaped track 3. The arc-shaped rack 31 and the opening 4 correspond vertically to the trajectory of the arc-shaped track 3.

[0023] Based on the above structural configuration, the trolley body 5 is slidably mounted on the outside of the arc track 3 via the bearing and guide wheel assembly 51. When the drive motor 52 at the bottom of the trolley body 5 rotates, the drive motor 52 drives the gear 53 at the power end to rotate. The gear 53 meshes with the arc rack 31 at the bottom of the arc track 3, thereby driving the trolley body 5 to slide along the trajectory of the arc track 3, and ensuring high sliding accuracy. During this process, the arc cable follower mechanism 6 provides a stable wired supply of strong and weak current.

[0024] Based on the above structure, this device was designed with increased pixel spacing to maximize heat dissipation area. The initial design of the LED display driver board used a pixel spacing of P12, while the actual required pixel spacing was P6. This would have necessitated an LED display driver board with an area greater than four times the required size. Due to space constraints, two boards were used, with the area of ​​the LED display driver board being equal to a multiple of the P6 spacing board. The light from each pixel of the P12 LED display driver board is extended to the P6 module display surface via a light guide, achieving photoelectric separation. Through the fiber optic light guide design, the light from each pixel can be bent and extended, allowing the P12 pixel spacing to be re-spoofed into a P6 pixel spacing display surface, increasing the brightness per unit square area to achieve the required brightness of ≥35000 cd / ㎡. Photoelectric separation also provides heat insulation, meeting the requirements of an ultra-high brightness, low-temperature display screen.

[0025] Similarly, each module is designed with an outer casing and equipped with a cooling fan. Each module forms a cooling system. Since the pixel pitch is P12, a standard outdoor brightness design, the cooling system only requires air circulation. The outer casing design facilitates module assembly, air circulation cooling, and overall screen installation and maintenance. The cooling fan draws in air, filters out dust, and then the air enters the inner cavity of the outer casing. It then passes through the gaps on both sides (the part between the LED display driver board and the inner wall of the outer casing) and is exhausted from the heat dissipation vents on the outside of the mounting plate.

[0026] The above embodiments are preferred embodiments of this utility model, but the embodiments of this utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of this utility model should be considered equivalent substitutions and are included within the protection scope of this utility model. In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
