[0005] The utility model provides a rolling guide shoe equipped with a lubrication device, which adopts the following technical solution:

[0006] A rolling guide shoe equipped with a lubrication device comprises a mounting seat, guide shoe seats are symmetrically mounted on the surface of the mounting seat, a plurality of placement grooves are provided on one side of two groups of guide shoe seats close to the center of the mounting seat, balls are arranged inside the plurality of placement grooves, first oil passages are arranged inside the two groups of guide shoe seats, second oil passages are connected between the plurality of placement grooves and the first oil passages, intermittent refueling mechanisms are arranged on the tops of the two groups of the first oil passages, the intermittent refueling mechanisms comprise two groups of oil storage tanks, refueling ports are provided on the tops of the two groups of oil storage tanks, movable plates are installed inside the two groups of oil storage tanks, baffles are installed on the bottoms of the two groups of movable plates close to the center of the oil storage tanks, and drive components are arranged between the two groups of baffles and the oil storage tanks.

[0007] By adopting the above technical solution, the staff adds the lubricating oil into the oil storage tank through the refueling port for storage, and drives the ball to rotate during the ascent or descent of the elevator. When the ball is rotating, the driving component drives the movable plate to reciprocate left and right, and then can drive the movable plate to continuously reciprocate left and right, thereby realizing intermittent opening of the first oil channel, facilitating the lubricating oil to flow into the placement groove through the first oil channel via the second oil channel to lubricate the ball, which can reduce the friction between the ball and the elevator slide rail, thereby realizing automatic lubrication and reducing the workload of maintenance personnel.

[0008] Optionally, dust plugs are provided inside the two groups of fuel filling ports.

When the first incomplete gear is meshed and connected with the toothed plate, as the first incomplete gear rotates, it can drive the toothed plate to move outward and drive the two sets of movable plates to move outward. When the two sets of movable plates move, they drive the two sets of baffles to move and move away from each other, thereby opening the first oil channel. When the second incomplete gear is meshed and connected with the toothed plate, as the second incomplete gear rotates, it can drive the toothed plate to move and drive the two sets of movable plates to move inward. When the two sets of movable plates move, they drive the two sets of baffles to move and move closer to each other, thereby closing the first oil channel. The baffle continuously performs left and right reciprocating motion, thereby realizing intermittent opening of the first oil channel.
