Problems solved by technology

[0004] The current guide rail elevators have the following problems: 1. It takes time and effort to install the guide rails, the installation speed is slow, and it is difficult to adjust the verticality and parallelism; 2. Because the parallelism and straightness between the guide rails are deformed with the settlement of the building, the operating comfort is poor; 3. The elevator is expensive and the production cost is high

Embodiment 1

[0023] Example 1. refer to Figure 1-5 . A trackless elevator, including a power mechanism and a load-carrying mechanism, the power mechanism includes a traction machine 3, a traction wheel 4, a guide wheel 5 and a traction rope 6, the traction machine 3 is equipped with a traction wheel 4, and the traction The rope 6 is wound on the traction wheel 4 and the guide wheel 5. The load-carrying mechanism includes a car 7 and a counterweight 8. The two ends of the traction rope 6 are respectively connected to the car 7 and the counterweight 8; There are several guide ropes 10 and upper and lower fixed templates (9, 19), and the two ends of the guide ropes 10 are respectively connected to at least two peripheries of the upper and lower fixed templates (9, 19), and the car 7 and the counterweight 8 pass through The guide shoes 11 on its upper and lower periphery pass through the guide rope 10; it is also provided with a safety wheel 14 and a safety rope 15, and the safety wheel 14 ...

Embodiment 2

[0024] Example 2. In the trackless elevator described in embodiment 1, installation holes 12 are established on the upper and lower fixed templates (9, 19), and the two ends of the guide rope 10 are respectively connected to at least two of the upper and lower fixed templates (9, 19) through the installation holes 12. on the perimeter.

Embodiment 3

[0025] Example 3. In the trackless elevator described in Embodiment 1 or 2, a tensioner 13 is installed on the guide rope 10 .

Abstract

The invention relates to a trackless lift which comprises a power mechanism and a loading operation mechanism. The power mechanism comprises a tractor, a traction wheel, a guide wheel and a traction rope, wherein the traction wheel is mounted on the tractor; the traction rope is wound on the traction wheel and the guide wheel; and the loading operation mechanism comprises a lift car and a counterpoise which are respectively connected with both ends of the traction rope. The trackless lift is characterized in that the loading operation mechanism is also provided with a plurality of guide ropes,an upper fixed template and a lower fixed template; both ends of each guide rope are respectively connected with at least two edges of the upper fixed template and the lower fixed template; and the lift car and the counterpoise penetrate through the guide ropes by peripheral guide shoes. The trackless lift is also provided with a safety wheel and a safety rope, wherein the safety wheel is respectively coaxial with the traction wheel and the guide wheel and arranged by a bearing; the safety rope is wound on the safety wheel; and both ends of the safety rope are respectively fixed on the lift car and the counterpoise. The guide rope takes the guiding action so that the lift has rapid mounting, convenient adjustment, low operation noise, good operation comfort and low production cost.

Description

technical field [0001] The invention relates to an elevator, in particular to a trackless elevator. Background technique [0002] At present, the elevator includes a power mechanism and a load-carrying mechanism; the power mechanism is composed of a traction machine, a traction wheel, a guide wheel and a traction rope. The traction wheel is installed on the traction machine, and the traction rope is wound on the traction wheel and the guide wheel. ;The load running mechanism is composed of a car and a counterweight. The guide rail is installed in the hoistway through the guide rail bracket, the car and the counterweight run on the guide rail, and the two ends of the traction rope are respectively connected to the car and the counterweight; After the speed change, the traction wheel is driven to rotate, and the traction force generated by the friction between the traction rope and the traction wheel groove realizes the lifting movement of the car and the counterweight to achi...
