Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to a gearless elevator traction device. Background Technology

[0002] In modern construction, elevators, as key equipment for vertical transportation, rely heavily on the performance of their traction systems to determine their safety, stability, and operational efficiency. Traditional elevator traction systems typically employ relatively simple structural designs, with conventional transmission paths for the wire ropes between components such as the traction sheave and guide sheave. This leads to problems such as uneven stress on the wire ropes and rapid wear, resulting in poor elevator stability, requiring frequent maintenance, and increasing operating costs. Furthermore, the sliding guide structure of the car and counterweight on the guide rails is not optimized, making the elevator prone to swaying during high-speed operation, affecting passenger comfort, and even posing certain safety hazards.

[0003] Based on the above, this utility model proposes a gearless elevator traction device, which can effectively solve the above problems. Utility Model Content

[0016] A gearless elevator traction device includes a car assembly and a counterweight assembly. The car assembly includes a car 1 and car guide rails 2 located on both sides of the car 1. A lower mounting frame 3 is fixedly connected to the bottom of the car 1, and first guide wheels 4 are respectively installed on both sides of the lower mounting frame 3. A mounting plate 5 is fixedly connected to the top of the car guide rails 2. One mounting plate 5 is fixedly connected to a first rope connecting frame 6, and the other mounting plate 5 is fixedly connected to a second rope connecting frame 7 and a traction machine 8. A traction sheave 9 is fixedly connected to the output end of the traction machine 8. The counterweight assembly includes a counterweight block 10 and counterweight guide rails 11 located on both sides of the counterweight block 10. A second guide wheel 12 is fixedly connected to the top of the counterweight block 10. The first guide wheel 4, the traction sheave 9, and the second guide wheel 12 are connected by a plurality of steel wire ropes (not shown in the figure).

[0017] The first rope connecting frame 6 of this utility model is fixed to one end of multiple steel wire ropes. The other end of the steel wire ropes passes sequentially through two first guide wheels 4, a traction sheave 9, and a second guide wheel 12 before being fixed to the second rope connecting frame 7. When the traction machine 8 drives the traction sheave 9 to rotate, the relative lifting and lowering movement of the car 1 and the counterweight 10 is achieved through the transmission of the steel wire ropes and under the guidance of the first guide wheels 4 and the second guide wheels 12. The connection between the car 1 and the counterweight 10 balances the weight of the car 1, ensuring the operation of the elevator. At the same time, the sliders on the car 1 and the counterweight 10 are tightly fitted with the guide rails, ensuring smooth sliding of the car 1 and the counterweight 10 during operation, which not only ensures passenger comfort but also eliminates safety hazards.

[0020] By setting the first slider 14 on the upper mounting frame 13 and the lower mounting frame 3, the stability of the car 1 during vertical lifting is increased.

[0021] Furthermore, in another embodiment, the upper and lower ends of the counterweight 10 are respectively fixedly connected to the second sliders 15, and the second sliders 15 are slidably connected to the counterweight guide rail 11.

[0022] By setting a second slider 15, the stability of the counterweight 20 when it moves up and down is increased.

[0023] Furthermore, in another embodiment, the traction machine 8 is a gearless traction machine.

[0024] By setting up a gearless traction machine 8 to directly drive the traction wheel 9, the gear mechanism is eliminated, reducing energy loss in the mechanical transmission process.
