Description

Technical Field

[0001] The utility model relates to the technical field of ground rail splicing, in particular to a splicing device for a trolley ground rail. Background Art

[0002] The trolley ground rail is a track used to support and guide the operation of the trolley. It is usually composed of two parallel rails. The cross-sectional shape and size of the rail can be selected according to actual needs. The trolley ground rail is usually installed on the ground or foundation. It can be fixed in one position or moved to other positions as needed. The design and use of the trolley ground rail can keep the trolley stable during operation, reduce shaking and sliding, and improve production efficiency and safety. In industrial production, the trolley ground rail is widely used in material handling, production lines, warehousing and logistics and other fields. In order to increase the length, the trolley ground rail will be spliced ​​through a splicing device.

[0003] The existing Chinese patent with announcement number CN215856975U discloses a rail docking device, including a latch housing mechanism and a lock hole housing mechanism. A locking mechanism is arranged inside the latch housing mechanism. One end of the locking mechanism is connected to a driving mechanism, and the driving mechanism is a rotating structure. The driving mechanism and the locking mechanism are connected through a flange bearing. A lock hole mechanism is arranged inside the lock hole housing mechanism, and a connecting mechanism is arranged at the top of the lock hole housing mechanism.

[0004] Although the above scheme has a simple structure and compact layout, low manufacturing cost and long service life, the overall portability of the track docking device is poor and it is inconvenient to move. In addition, the trolley rails need to be moved manually when docking, which is prone to certain errors and affects the accuracy of splicing. Therefore, it does not meet the existing needs. In this regard, we propose a splicing device for trolley rails. Utility Model Content
