Abstract

The invention provides an elevator with a supporting rod type safety device. The elevator is characterized by comprising a first winch, wherein a first motor is connected with the first winch by a first belt; one end of a first traction cable is arranged on a second frame; the other end of the first traction cable is arranged on the first winch by a movable pulley; the movable pulley is connected with an elevating box by a steel wire rope; the elevating box is respectively connected with slide blocks on slide rails on two sides of the elevating box by two supporting rods; a second winch is arranged below the slide rails; one end of a second traction cable is arranged on the second winch; the other end of the second traction cable is respectively connected with the two slide blocks by two supporting rods; and a second motor is connected with the second winch by a second belt. The elevator with the supporting rod type safety device, provided by the invention, has the advantages of simple structure, low cost, lower requirement on motor load capacity and overload protective effect; shortcomings in the prior art are overcome; and dropping and overrunning accidents of the elevating box can be prevented.

Description

technical field [0001] The invention relates to an elevator with a brace type safety device, belonging to the technical field of elevators. Background technique [0002] Among the existing elevators, some are simple in structure and low in cost, but the safety factor is very low, and accidents such as the wire rope being pulled off and the hanging rail rushing to the top are prone to occur; Technical content products, high cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an elevator with low cost, simplified structure and high safety factor. [0004] In order to solve the above-mentioned technical problems, the technical solution of the present invention is to provide a lift with a pole-type safety device, which is characterized in that: it includes a first winch, and the first motor installed on the first frame is connected with the first belt through the first belt. The first hoist is connected; one end ...
