Embodiment Construction
[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0013] Such as Figure 1 to Figure 3 As shown, a dual-host synchronously driven elevator consists of two traction machines, car device 1, counterweight device 2, car guide device, counterweight guide device, car reverse sheave 6, counterweight reversing sheave 7, guide wheel 5, steel wire rope 8, engine room beam 9 and wire rope rope end 10 are formed.
[0014] The two traction machines and the two guide wheels 5 are respectively fixed on the beams 9 in the machine room, the car device 1 is respectively connected with the car guide device to move up and down, and the counterweight device 2 is connected with the counterweight guide device to move up and down. A pair of car anti-rope pulleys 6 are installed on the front and rear of the car device 1, and two counterweight anti-rope pulleys 7 are installed on the upper part of the counterweight device 2; o...

The invention relates to a two-main-machine synchronous drive elevator. Two traction machines and two guide wheels are fixed to a machine room shelf beam. Car devices are connected with car guiding devices in a matched mode. Counterweight devices and counterweight guiding devices are connected in a matched and guided mode. The front and back portions on the top of each car device are each provided with a pair of car diversion sheaves. Two counterweight diversion sheaves are arranged on the tops of the counterweight devices. One end of a steel wire rope is fixed to one side of the machine room shelf beam. The other end of the steel wire rope sequentially passes through one counterweight diversion sheave on the counterweight devices, the first traction machine, the two car diversion sheaves on the front portion of the car devices, the two guide wheels on the machine room shelf beam, the two car diversion sheaves on the rear portions of the car devices, the second traction machine and the other counterweight diversion sheave on the counterweight devices and then is fixed to the other side of the machine room shelf beam. Two traction systems are connected in series through one steel wire rope to achieve two-main-machine synchronous drive. Due to the fact that the two traction systems drive the front portions and the rear portions of the cars respectively, the phenomenon that the cars are inclined due to unbalance loading after the elevator is started is avoided during unbalance loading.
Description
technical field [0001] The invention relates to a synchronous drive elevator, in particular to a dual-host synchronous drive elevator. Background technique [0002] Large-car car elevators and large-tonnage freight elevators are no longer applicable to traditional single-engine elevators, and dual-engine synchronously driven elevators are required as freight elevators. However, it is necessary to solve the problem that the car is unbalanced before and after starting. Compared with traditional single-host elevators, dual-host elevators use existing hosts to solve the problem of unbalanced lifting of the elevator car at the moment of starting and the problem of tilting the car after starting caused by the unbalanced load of the car. Demand for large tonnage freight elevators and large car elevators. Contents of the invention [0003] The present invention provides a dual-host synchronously driven elevator, which is used to meet the requirements of a large-tonnage freight e...
