[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] See also Figure 1-Figure 6 The frame traction type sliding elevator comprises a motor 1, a traction assembly, an upper track 4, a lower track 5, an upper traction wheel 6, a lower traction wheel 7 and a manned platform 8. The traction assembly comprises a rope winding wheel 2 and a traction rope 3. The motor 1 is driven to connect the rope winding wheel 2. The motor 1 is relatively fixed and drives the rope winding wheel 2 to rotate through a reducer. One end of the traction rope 3 is connected to the rope winding wheel 2 and is wound on the rope winding wheel 2 or output by the rope winding wheel 2 when the rope winding wheel 2 rotates. The upper track 4 and the lower track 5 are respectively inclined along the step ladder T. The manned platform 8 is arranged between the upper track 4 and the lower track 5. The upper traction wheel 6 rolls on the step ladder T. In the upper track 4, the lower traction wheel 7 rolls in the lower track 5, the upper traction wheel 6 is arranged on the top of the manned platform 8, and the lower traction wheel 7 is arranged on the bottom of the manned platform 8, and the traction rope 3 is connected to the bottom of the manned platform 8 through the traction assembly; when the rope wheel 2 reels in the traction rope 3 (at this time the motor 1 rotates forward), the traction rope 3 pulls the bottom of the manned platform 8 to drive the manned platform 8 to rise along the upper track 4 and the lower track 5, so as to achieve the purpose of manning people upstairs; when the rope wheel 2 outputs the traction rope 3 (at this time the motor 1 reverses), the manned platform 8 descends along the upper track 4 and the lower track 5 under the action of gravity, so as to achieve the purpose of manning people downstairs.

[0024] A plurality of support rods 9 are arranged between the upper rail 4 and the lower rail 5. The upper rail 4, the lower rail 5 and the support rods 9 form a support frame. A support frame 19 is detachably arranged at the high end and / or the low end of the support frame (connected by screws). The support frame can improve the structural strength of the entire sliding elevator. When someone moves large furniture, the support frame 19 can be removed to facilitate the movement of the large furniture. After the large furniture is moved, the support frame 19 can be quickly installed back.

[0025] A buffer module 10 is provided at the lower end of the upper track 4 and the lower track 5. When the manned platform 8 descends to the lower end of the step ladder T, the buffer module 10 acts on the upper traction wheel 6 and / or the lower traction wheel 7 to produce a buffering effect on the manned platform 8 to prevent the manned platform 8 from sliding out of the upper track 4 and the lower track 5. The buffer module 10 is a spring or a hydraulic buffer. The hydraulic buffer is a conventional hydraulic buffer on the market. Its main structure is composed of a body, a piston rod, an inner tube, a piston, hydraulic oil, a spring, etc. When the piston rod is impacted by an external force, it will drive the piston to squeeze the hydraulic oil in the inner tube. After the hydraulic oil is pressurized, it will be discharged from the oil discharge hole on the inner tube, and at the same time, it will flow back to the upper cavity of the piston from the chamber between the inner tube and the body and the oil return hole, thereby generating resistance; when the external force disappears, the spring will bounce the piston back to the starting point, and the hydraulic oil will flow back to the lower cavity of the piston through the oil return hole and the oil discharge hole in turn, waiting for the next action.

[0026] The traction assembly includes a plurality of fixed pulleys 11 arranged on the upper track 4 and / or the lower track 5. The traction rope 3 is wound around the fixed pulleys 11.

At this time, the upper traction wheel 6 serves as a driven wheel, and the traction rope 3 can also simultaneously pull the connecting shaft 13 between the upper traction wheels 6 and the connecting shaft 13 between the lower traction wheels 7 to move, and then the connecting shaft 13 drives the upper traction wheel 6 and the lower traction wheel 7 to roll.
