Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides an embodiment: a jack for detecting the bearing pressure of a foundation comprises a jack body 1, wherein the jack body 1 is composed of a jack shell 2 sleeved with a jack inner column 3, a base plate 4 is arranged at the top end of the jack inner column 3, two inner bins 10 are arranged in the right side surface of the jack shell 2, the upper end and the lower end of each inner bin 10 are fixedly connected with connecting rods 5, the upper end and the lower end of each connecting rod 5 are symmetrically fixed with fixing rods 6, the fixing rods 6 are hinged with hinge rods 8 through hinge buttons 7, each hinge rod 8 is hinged with another hinge rod 8 through another hinge button 7, the other hinge rod 8 is hinged with the other fixing rod 6 through another hinge button 7, universal wheels 9 are fixed on the lower hinge rods 8, the hinge positions of the left fixing rods 6 and the hinge rods 8 are located to the bottom ends of the universal wheels 9, the length of the universal wheels 9 is smaller than that of the inner bins 10, the universal wheels 9 can be conveniently retracted into the inner bins 10, the bottom end of the jack body, and four salient blocks 13 are fixed on the bearing plate 11, a central block 12 is fixed at the middle position of the bearing plate 11, the horizontal heights of the four salient blocks 13 are equal to the horizontal height of the top end of the central block 12, the jack body 1 cannot incline when being sleeved with the bearing plate 11, so that the ground detection data is accurate, a central block bin 15 matched with the central block 12 is arranged at the middle position of the bottom end inside the jack body 1, salient block bins 16 matched with the salient blocks 13 are arranged on the left side and the right side of the bottom end inside the jack body 1, the area of the central block 12 is larger than that of the salient blocks 13, so that the jack body 1 is more stable and firm, friction pads 14 are glued on the two sides of the bottom end of the jack body 1, the friction force with the ground is increased, and the measurement data deviation caused by slight movement of the jack body 1 is reduced.
