The track assembly 10 includes an outer track 11, an inner track 12, and a transmission assembly 13. The outer rail 11 includes side walls 110, a front wall 111, and a rear wall 112, the front wall 111 and the rear wall 112 being parallel to each other. The side walls 110 are located between the front wall 111 and the rear wall 112 and are perpendicular to the front wall 111 and the rear wall 112. The outer rail 11 is a C-shaped or U-shaped metal groove with edges. The inner rail 12 is a C-shaped or U-shaped metal channel with edges, the total width of which is smaller than that of the outer rail 11. The inner rail 12 is provided with an escape groove 120. The transmission assembly 13 includes four front and rear rollers 14 and a left and right rolling structure 15. The number of front and rear rollers 14 can be increased as necessary (track length), but must be increased in pairs. The diameter of the front and rear rollers 14 is the same as the groove width of the outer rail 11, so that the front and rear rollers 14 can roll in the C-shaped or U-shaped groove of the outer rail 11 without excessive clearance. The left and right rolling structure 15 includes four left and right rollers 151 and a positioning assembly 152. The positioning assembly 152 includes a top rod 153, two top support brackets 154 and two cross positioning rods 155. The two cross positioning rods 155 are rotatably connected and in an X shape. Each top support bracket 154 is fixed to a cross positioning rod 155, and both ends of the top rod 153 are fixed to two top support brackets 154.

The platform assembly 20 includes a mounting bar 21, a frame 22, and a plate 23. The frame 22 is formed by at least 3 frames (5 frames in this embodiment) and is mounted on the top of the mounting rod 21 by screws. The flat plate 23 is mounted on the frame 22 in a covering manner, and may be covered entirely or partially.

The power assembly 30 includes a motor 31, a motor bracket 32, a coupling 33, a jack screw 34, a lead screw 35, a nut kit 36, and a nut bracket 37. The motor 31 is fixedly arranged on the motor bracket 32, the coupler 33 is connected with the screw rod 35, and the jack screw 34 connects the coupler 33 and the screw rod 35 to the output shaft of the motor 31. The nut set 36 is fixedly mounted on the nut bracket 37, and the lead screw 35 is connected to the nut set 36 by the screw thread of the nut set 36. The nut assembly 36 may be a single nut, a longer nut tube, or an assembly of more than 2 nuts.

When the electric elevating platform device is assembled, the inner rail 12 is accommodated in the outer rail 11, the front and rear rollers 14 are rotatably mounted on the side surface of the inner rail 12, and the edges of the front and rear rollers 14 contact the front wall 111 and the rear wall 112 of the outer rail 11. The two cross positioning rods 155 are rotatably mounted to the inner rail 12, and the edges of the left and right rollers 151 are in contact with the side wall 110 of the outer rail 11. At this time, the axes of the left and right rollers 151 are perpendicular to the axes of the front and rear rollers 14. The motor bracket 32 of the power assembly 30 is fixed to the inner rail 12, and the nut bracket 37 is fixed to the outer rail 11. The mounting bar 21 of the platform assembly 20 is secured to the inner rail 12.

When the electric lifting platform device is used, the motor 31 drives the screw rod 35 to rotate, the screw rod 35 rotates in the nut suite 36, the nut suite 36 is fixed, and the screw rod 35 drives the inner rail 12 to move relative to the outer rail 11 by utilizing the reverse thrust of the threads. When the inner rail 12 moves relative to the outer rail 11, the left and right rollers 151 and the front and rear rollers 14 roll, so that rolling sliding is realized between the inner rail 12 and the outer rail 11, and the rolling type sliding rail has small moving resistance and low power consumption. Due to the fact that

The groove width of the outer rail 11 is equal to the diameter of the front and rear rollers 14, the front and rear rollers 14 and then the inner rail 12 are restrained from swinging (left and right directions (relative) cannot swing, and 4 front and rear rollers 14 form 4 supporting points to ensure that the whole slideway surface cannot swing left and right).

The left and right rollers 151 mounted on the cross positioning rod 155 are pressed by the push rod 153 to roll on the side wall 110 of the inner rail 12, and can drive the inner rail 12 to slide relative to the outer rail 11. And 2 wheels in the opposite directions of the left and right rollers 151 are respectively pressed on the opposite inner walls of the inner rail 12 and are restrained by the width of the inner walls, so that the inner rail 12 is restrained from swinging (in the front-back direction (relative) and not swinging, 4 left and right rollers 151, and 2 groups of cross positioning rods 155 are positioned at the center of the inner rail 12, so that the inner rail 12 is ensured to be at the center of the outer rail 11 and not swinging back and forth, and the whole slide way is ensured not to swing back and forth by adding a fixed point of a screw rod 35.

The track assembly 10 may be used directly as a monorail or may be assembled in pairs into a platform. The track assembly 10 can be used for a push-pull device independently and directly without loading power, and can also be used for loading a hand-cranking device to replace a motor 31 at the position of a motor 31, so that the hand-cranking device is driven to lift. The track assembly 10 may be used for vertical track lifting applications and may be mounted in any orientation, including transversely, for use as a portable track. The track can be controlled to lift or descend by controlling the positive and negative rotation of the motor 31.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
