Detailed Description

The technical solution of the present invention will be described in detail by the following specific examples.

As shown in fig. 1 to 3, the shallow pit home use elevator includes a car 1, a car frame 2, a counterweight 3, a traction machine 4, a main guide rail 5 and an auxiliary guide rail 6, the car 1 is slidably arranged on the main guide rail 5, the counterweight 3 is slidably arranged on the auxiliary guide rail 6, in the hoistway, the two main guide rails 5 are distributed left and right, the two auxiliary guide rails 6 are distributed front and back, the counterweight 3 is positioned on the left side of the car 1, the two auxiliary guide rails 6 are arranged on an auxiliary guide rail support 7, the auxiliary guide rail support 7 is a U-shaped support, the front end and the back end of the U-shaped support are fixed on the hoistway 10, the main guide rail 5 on the left side of the car is fixed in the middle of the U-shaped support, and the main.

The top of the auxiliary guide rail 6 is provided with a tractor base 9, the tractor 4 is installed on the tractor base 9, the tractor 4 is a double-wheel tractor with two traction wheels 41, the two traction wheels are positioned at the front side and the rear side of the main guide rail 5, the top of the counterweight 3 is provided with two counterweight return pulleys 31 which are arranged front and rear, and a counterweight rope hitch plate 32 is arranged in the tractor base 9, namely the tractor base and the counterweight rope hitch plate are of an integrated structure. Two pairs of car diverting pulleys 11 in front and back are arranged on the car frame upper beam above the car 1, each pair of car diverting pulleys comprises two car diverting pulleys distributed left and right, and a car rope hitch plate 12 is arranged at the top of the main guide rail on the right side. One rope end of a steel wire rope wound on each traction wheel downwards bypasses the counterweight pulley and upwards fixes the steel wire rope on the counterweight rope hitch plate, and the other rope end of the steel wire rope downwards bypasses a pair of car pulley and upwards fixes the steel wire rope on the car rope hitch plate. That is to say, two traction wheels, two counter-weight diversion sheaves and two pairs of cage diversion sheaves are symmetrically distributed on the front side and the rear side of the plane where the two main guide rails are located, and the winding methods of the steel wire ropes on the two traction wheels are the same.

Preferably, an electronic speed limiter 13 and a left safety gear and a right safety gear 14 are mounted on the upper beam of the car frame, the electronic speed limiter 13 is positioned between the two safety gears 14, and the electronic speed limiter controls the safety gears to act through a linkage device. Compared with the existing household elevator, the safety gear is arranged on the lower beam of the car frame, the speed limiter is fixed on the wall of the hoistway, the occupied height of parts below the car can be reduced, and the occupied width space of the hoistway is reduced.
