Problems solved by technology
[0004] Aiming at the deficiencies of the prior art, the present invention provides a jack level correction device, which solves the problem that the existing jack does not have a targeted leveling device, and the levelness of the base completely depends on the levelness of the ground or the support on the base surface of the jack. , For example, when the base itself is placed at an inclination, it is easy to tilt the support for its support, causing the jack base to not be stable enough and at the same time, slipping out of the support position and causing accidents

The invention discloses a horizontal correcting device for a jack. The device comprises a jack body. The bottom of the jack body is fixedly connected with a stabilizing circular plate. The front of the jack body is fixedly connected with a panel. According to the horizontal correcting device for the jack, the depth of a jacking pipe inserted into a supporting steel cylinder is changed by the thread displacement of a twisting bracing sleeve on a jacking pipe, so that the horizontal bracing height, corresponding to the bottom, of the stabilizing circular plate is changed, and the stabilizing circular plate is adjusted to a horizontally balanced state. At the same time, a supporting and stabilizing sphere swings freely inside a spherical groove of a supporting and stabilizing block, so that the inclination of the supporting and stabilizing block is the same as the inclination of an adjusting supporting plate. The stabilizing circular plate is stabilized and supported by arranging the supporting and stabilizing sphere, inserting the supporting and stabilizing block, and adjusting a movable part. A supporting bottom plate is used to improve the supporting strength of the stabilizing circular plate, so as to further reduce the potential safety hazard when the jack is used.
Description
technical field [0001] The invention relates to the technical field of jack level correction, in particular to a jack level correction device. Background technique [0002] The jack refers to a light and small lifting device that uses a rigid lifting piece as a working device, and lifts heavy objects in a small stroke through the top bracket or bottom claw. The jack is mainly used in factories, mines, transportation and other departments as vehicle repair and For other lifting, supporting and other work, its structure is light and firm, flexible and reliable, easy to carry and operate. At present, when the jack is being lifted, the use requirement is to place the jack to a horizontal state so that the jacking rod of the jack is displaced at a vertical angle, so as to prevent the jack from slipping out and causing an accident. The leveling device is permanently installed, and the levelness of the base depends entirely on the levelness of the ground. For example, when the bas...
