Description

Technical Field

[0001] The utility model relates to the technical field of trolley use, in particular to a trolley driving structure. Background Art

[0002] Trolley furnaces are common high-temperature heating equipment, widely used in industrial production and laboratories, and are often used for heat treatment of products. The trolley in a trolley furnace must move forward or backward beneath the furnace to access and place workpieces. Typically, the trolley is manually or electrically driven, and requires rail support. To maintain smooth operation, the rails must be level and stable, requiring high site requirements. Leveling and grooving of the ground may also be required, making installation challenging.

[0003] Utility model patent CN206927232U discloses a trolley drive device comprising a bracket, a driving wheel, a driven wheel, a connector, a drive assembly, and a movable platform. The bracket can be installed in a pit. The driving wheel is rotatably mounted on one end of the bracket. The driven wheel is rotatably mounted on the other end of the bracket. The connector is sleeved over the driving wheel and driven wheel, rotating with the driving wheel and driving the driven wheel. The drive assembly is connected to the driving wheel to drive the driving wheel. The movable platform is slidably mounted on the bracket and connected to the connector. The movable platform can be connected to the trolley to drive the trolley. The movement of the trolley can be controlled by controlling the drive assembly, eliminating auxiliary operations such as manually moving the power head. This improves the degree of automation, improves work efficiency, and reduces labor intensity. However, the large distance between the driving wheel and the driven wheel of this device can cause sagging or excessive tension in the intermediate portion of the connector during transmission. This can affect the proper tensioning and efficient transmission of the connector over long-term use, thus necessitating improvements. Utility Model Content

The matching track 9 below the driving wheel 5 and its contact design with the trolley enhance the stability of the entire drive system and ensure the stable trajectory and direction control of the trolley during movement.

[0026] The setting of the support component is an optimization of the chain 8, a key link in power transmission. By providing a support structure, the problem of sagging or excessive tension of the chain 8 during the transmission process is avoided, and the normal tensioning and efficient transmission of the chain 8 are ensured, thereby further improving the stability and service life of the entire drive system, and also improving the operating efficiency and working effect of the trolley.

[0027] In this embodiment, the support assembly includes two vertical plates 10 arranged in parallel, a fixed shaft 11 is provided between the two vertical plates 10, and the middle part of the fixed shaft 11 is rotatably connected to a support sprocket 12 engaged with the chain 8.

The protective cover can be installed on the bottom of the trolley body 1 by bolt connection to protect the driving motor 2 and the reducer 3 from damage caused by physical collision.

[0031] The working principle of the present invention is as follows: The trolley drive structure is designed to provide the trolley with efficient and smooth movement. Through the efficient output of the drive motor 2 and the precise coordination of the coupling and the reducer 3, efficient conversion and stable transmission of power are ensured. The use of the reducer 3 reduces the transmission speed, thereby improving the driving efficiency and torque, so that the driving wheel 5 can efficiently drive the trolley forward.

The matching track 9 below the driving wheel 5 and its contact design with the trolley enhance the stability of the entire drive system and ensure the stable trajectory and direction control of the trolley during movement.

[0032] The setting of the support component is an optimization of the chain 8, a key link in power transmission. By providing a support structure, the problem of sagging or excessive tension of the chain 8 during the transmission process is avoided, and the normal tensioning and efficient transmission of the chain 8 are ensured, thereby further improving the stability and service life of the entire drive system, and also improving the operating efficiency and working effect of the trolley.
