Abstract

The invention relates to the technical field of jack-related equipment, and discloses an upright type jack top extension supporting device. The upright type jack top extension supporting device comprises a cylinder body, the cross section of the outer side wall of the cylinder body is square, the cross section of the inner side wall of the cylinder body is round, the cylinder body is not providedwith a base, the top of the cylinder body is fixedly connected with a round supporting disc through locking screws, a round soft rubber block is adhered to the top of the inner side of the cylinder body, arc-shaped placement grooves are formed in the inner walls of the left side and the right side of the cylinder body, two movable through holes are formed in each of the left side face and the right side face of the cylinder body, movable reinforcing rings are welded at the movable through holes in the left side face and the right side face of the cylinder body, polished rods are arranged on the inner sides of the four reinforcing rings in a penetrating and inserting mode, and the four polished rods penetrate through the inner sides of the corresponding movable through holes correspondinglyand extend to the inner sides of the corresponding arc-shaped placement grooves. According to the upright type jack top extension supporting device, the uniformity of clamping stress on the top of ajack is guaranteed, so that the top of the jack is well fixed.

Description

technical field [0001] The invention relates to the technical field of jack-related equipment, in particular to a vertical jack top extension support equipment. Background technique [0002] Jacks are often used during maintenance or assembly. Vertical jacks are widely used because of their small size and portability. However, vertical jacks have certain limitations in use because of the limited height they support. For taller When lifting an object, people generally use stones or hard objects at the bottom of the vertical jack as a base pad to increase the support height of the jack. The gravity is easy to cause the base pad to break or the jack to move, resulting in safety hazards. Some equipment for fixed support at the bottom of the vertical jack clamps and fixes the bottom of the vertical jack to ensure its clamping stability, but the vertical jack The shape of the bottom of the jack is generally irregular, and the uneven clamping force on the bottom of the jack can ea...
