Problems solved by technology

[0002] The positioning machine is proposed to solve the problem of complete institutionalization of the installation and positioning of the underground hydraulic support. For a long time, the installation and positioning has been in a backward manual operation state, with strong labor, low work efficiency and many safety hazards. Change this The noise in this state is very high, and all levels and departments are actively developing, but so far there is still no competent machine. The lifting mechanism on the existing positioning machine cannot be used in a narrow space due to its large structure. It is imminent to study a lifting mechanism for narrow spaces

Embodiment 1

[0017] Such as figure 1 As shown, the present invention uses an oil cylinder to realize a parallelogram mechanism with a small stroke and a large displacement, including a base, a first oil cylinder 1, a first bottom rod 2, a first ejector rod 3, and a plurality of first intermediate rods 4 and a plurality of second rods. The middle rod 5, the first bottom rod 2 and the first push rod 3 are telescopic rods, the first oil cylinder 1 and the first bottom rod 2 are all arranged on the base, and the first oil cylinder 1 is vertically arranged, The first bottom bar 2 is arranged horizontally, the plurality of first intermediate bars 4 are arranged parallel and equidistant in the vertical plane, and the plurality of second intermediate bars 5 are also arranged parallel and equidistant in the vertical plane, so The first intermediate rod 4 and the second intermediate rod 5 are all intersected in pairs, and the intersection position of the first intermediate rod 4 and the second inter...

Embodiment 2

[0019] The number of the first oil cylinder 1 is two, and the two first oil cylinders 1 are horizontally parallel and oppositely arranged, and the cylinder body of one of the first oil cylinders 1 is hinged with the bottom end of the first intermediate rod 4 at the lowest end , the piston rod is hinged with the bottom end of the second intermediate rod 5 at the lowest end, the cylinder body of the other first oil cylinder 1 is hinged with the top end of the first intermediate rod 4 at the top end, and the piston rod is hinged with the top end of the first intermediate rod 5 at the top end The top ends of the second middle rod 5 are hinged together to control the expansion and contraction of the first oil cylinder 1 and adjust the height of the first push rod 3 .

[0020] All the other parts are the same as embodiment one.

Embodiment 3

[0022] The piston rod of the first oil cylinder 1 is provided with an inner connecting rod 6, and the cylinder body of the first oil cylinder 1 is provided with an outer connecting rod 7. The inner connecting rod 6 is located inside the outer connecting rod 7, and the inner connecting rod 6 and the outer connecting rod 7 are arranged in parallel, the inner connecting rod 6 and the outer connecting rod 7 can move alternately under the expansion and contraction of the first oil cylinder 1, and one end of the inner connecting rod 6 is hinged to the piston rod of the first oil cylinder 1 Above, the other end of the inner connecting rod 6 is hinged to one end of the second intermediate rod 5, one end of the outer connecting rod 7 is hinged to the cylinder body of the first oil cylinder 1, and the other end of the outer connecting rod 7 is connected to One end of the first intermediate rod 4 is hinged to control the expansion and contraction of the first oil cylinder 1 and adjust the...

Abstract

The invention belongs to the technical field of hydraulic locating machines and provides a parallelogram mechanism capable of realizing a small stroke and a long movement distance through an oil cylinder. The parallelogram mechanism overcomes the defects in the prior art and is simple in structure and capable of operating in a narrow and small space and realizing a small stroke and a long movement distance through the oil cylinder. According to the technical scheme, first bottom rods and first top rods are telescopic rods, and the first bottom rods are horizontally arranged; multiple second middle rods are arranged in parallel at equal intervals on a vertical plane; each first middle rod and the corresponding second middle rod are arranged in an intersecting mode, wherein the intersecting position of each first middle rod and the corresponding second middle rod is located on the middle portions of the two rods, and the two rods are hinged together at the intersecting position; a piston rod of the first oil cylinder is controlled to stretch and contract so that the height of the first top rods can be adjusted. The parallelogram mechanism capable of realizing a small stroke and a long movement distance through the oil cylinder can be widely applied to the field of hydraulic locating machines.
