Description

Technical Field

[0001] This utility model relates to the field of logistics transfer equipment technology, and in particular to a rail-mounted traction device for heavy-duty energy storage boxes. Background Technology

[0002] When transferring heavy-duty energy storage boxes within existing factory buildings, a chain-driven, unpowered trolley is typically used. Traditional traction devices propel the trolley forward when the chain moves in the forward direction, but when the chain moves in the reverse direction, it causes the trolley to move backward, interrupting the production cycle and failing to meet the requirements for efficient linear transfer. Therefore, there is an urgent need for a unidirectional propulsion traction device that can prevent the energy storage boxes from moving backward. Utility Model Content

[0003] This application addresses the shortcomings of the prior art by providing a rail-mounted traction device. Through the coordinated action of a push rod mechanism and a damping mechanism, the forward and backward displacement of the traction mechanism is converted into a unidirectional push rod swing, so that the chain automatically disengages from the propulsion state when it moves in the opposite direction, thus preventing the energy storage box from reversing.

[0004] The technical solution adopted in this utility model is as follows: A rail-mounted traction device for heavy-duty energy storage boxes includes multiple base frame profiles installed on the ground. A running groove is installed on the upper part of the base frame profiles, and a chain track is installed on the lower part of the base frame profiles. A traction mechanism is slidably arranged in the running groove along its straight direction. A push rod mechanism is arranged inside the traction mechanism, and damping mechanisms are arranged on both sides of the traction mechanism. The push rod mechanism converts the forward and backward displacement of the traction mechanism into the rotational swing of the push rod through the damping mechanisms.

[0005] Furthermore, each of the base frame profiles has a rectangular hole on its upper part, and the upper and lower edges of the running groove are limited and set in the rectangular hole formed relative to the base frame profile; the lower center of the base frame profile has an open cavity and a spaced square groove, and a closed-loop chain drive mechanism is provided between the open cavity and the square groove.

[0006] Furthermore, the traction mechanism includes an outer frame with running guide wheels on both sides and a downward-facing engagement caliper at the front of the outer frame, which engages with the chain.

[0007] Furthermore, the push rod mechanism includes a guide rail disposed inside the center of the outer frame, a slider slidably disposed on the guide rail, a rotating shaft disposed below the center of the outer frame, a push rod body rotatably connected to the rotating shaft, and the middle part of the push rod body rotatably disposed at the tail end of the slider.

[0008] Furthermore, the damping mechanism includes limiting rings disposed on both sides of the outer frame, a damping box is installed between the limiting rings and the inner wall of the running groove, a spring is disposed inside the damping box, an end cap is disposed at the end of the spring, and the end cap frictionally abuts against the inner wall of the running groove.

[0009] The advantages of this utility model over the prior art are as follows: 1) Unidirectional propulsion: When the chain is running in the forward direction, the meshing caliper drives the traction mechanism forward, the push rod body is in the ejected state, the friction of the damping mechanism is overcome, and it moves forward in one direction to push the energy storage box; when the chain is running in the reverse direction, the damping mechanism generates frictional resistance, causing the slider to move backward relative to the guide rail, the push rod body rotates around the pivot and retracts, disengaging from the propulsion state; 2) Anti-reverse protection: After the push rod is retracted, it only moves backward with the traction mechanism under no-load, and the energy storage box remains stationary, which is in line with the continuous production cycle. 2) Stable structure: The base frame profile and double groove design ensure precise guidance of chain drive and traction motion.
