Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clear, the present invention is further described in detail through the accompanying drawings and embodiments. It should be understood, however, that the description herein of specific embodiments is for purposes of illustration only and is not intended to limit the scope of the present disclosure.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and the terms used herein in the specification of the present invention are for the purpose of describing particular embodiments only and are not intended to limit the present invention.
As shown in fig. 1, 2 and 3, a shallow pit car stopping device comprises a fixed seat 1; a groove for placing the clamping guide rail 4 is formed in the fixed seat 1; the left side and the right side of the fixed seat 1 at the groove position are respectively provided with a fixed wedge block 11 and a movable wedge block 12; the movable wedge block 12 is movably connected to the fixed seat 1 through a sliding groove connected to the groove surface; one side of the narrow edge of the movable wedge block 12 is fixedly connected with a spring part 2; the other end of the spring part 2 is fixedly connected to a side plate of the fixed seat 1; a stopper handle 3 is also arranged on one side of the fixed seat 1; the bottom edges of the two sides of the fixed seat 1 are fixedly connected with an abutting clamping plate 13 through bolts; one side end face of the abutting clamping plate 13 is close to the guide rail 4, the other side end face is partially connected to the fixed seat 1, and the other side end face is partially connected with the fixed wedge block 11 and the movable wedge block 12.
In the preferred embodiment, the fixed wedge 11 is fixed on the side of the fixed seat 1 opposite to the movable wedge 12 by a bolt.
In the preferred embodiment, the movable wedge 12 is a right trapezoid, and one side of the vertical side of the trapezoid is close to the guide rail 4, and one side of the inclined side of the trapezoid is close to the groove surface of the fixed seat 1, and the groove surface is arranged obliquely.
The working process is as follows: after entering the pit, a person holds the stopper handle 3, pushes the stopper to a specified position on the guide rail 4, and slightly pulls down the stopper to clamp the stopper on the guide rail 4. When the elevator car presses against the stop. The fixed seat 1 of the stopper is stressed by a downward force, the fixed seat 1 and the movable wedge block 12 form a triangular structure, the movable wedge block 12 and the fixed seat 1 can move, friction force exists between the movable wedge block 12 and the guide rail 4, the larger the downward force is stressed on the fixed seat 1, the larger the lateral force of the wedge block of the movable wedge block 12 which is extruded is, the friction force between the movable wedge block 12 and the guide rail 4 is increased along with the increase of the friction force, the friction between the movable wedge block 12 and the guide rail 4 prevents the whole stopper from moving downwards, so that the elevator is stopped at the position and cannot move downwards, and when the elevator leaves the device, the movable wedge block 12 is reset through the spring part 2.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention, which is intended to cover any modifications, equivalent substitutions or improvements made within the spirit and scope of the present invention.
