Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] The invention provides a support shoe structure of a kind of rectangular shield machine propulsion cylinder, which is installed at the front end of the piston rod of the propulsion cylinder, and is used to transmit the push force of the propulsion cylinder to the shield machine. The support shoe structure of the similar rectangular shield propulsion cylinder of the present invention is designed as a hemispherical ball head, and the spherical surface is set corresponding to the end of the piston rod, and the mounting surface opposite to the spherical surface is directly connected to the top plate, which greatly reduces the The space occupied by the support shoe structure is reduced, and the installation length of the entire oil cylinder is shortened. The shortening of the installation length of the oil cylinder directly shortens the struct...

Abstract

The invention relates to a spreading shoe structure of a quasi-rectangular shield pushing oil cylinder. The spreading shoe structure comprises a ball, a top plate and a flexible plate, wherein the ball is installed at the end of a piston rod and provided with a spherical surface and an installing surface opposite to the spherical surface, and the spherical surface of the ball corresponds to the piston rod; the top plate is fixed to the installing surface of the ball; the flexible plate is fixed to the top plate. The spherical surface of the ball of the spreading shoe structure is arranged corresponding to the piston rod, and the top plate is connected between installing surfaces; in this way, space needed for the spreading shoe structure is greatly reduced, the installing length of the whole oil cylinder is reduced, then the length of a shield structure is also reduced, the manufacturing cost of a whole set of equipment is lowered, and the cost is effectively lowered. The ball can rotate by 360 degrees, and overall installing of the oil cylinder is facilitated.

Description

technical field [0001] The invention relates to a propulsion cylinder, in particular to a support shoe structure similar to a rectangular shield propulsion cylinder. Background technique [0002] The support shoe structure of the rectangular shield propulsion cylinder of the existing shield machine is as follows: figure 1 As shown, the shoe structure includes a ball head 12 installed on the front end of the oil cylinder 11, the ball head 12 is connected to the top 13 through the mounting plate 14, the ball head 12 is connected to the front end of the oil cylinder 11 through the connecting plate 15, and the connecting plate 15 and the front end of the oil cylinder 11 are connected. A safety chain is tied between the mounting plates 14 . Such a shoe structure takes up a lot of space, which makes the length of the shield machine longer and the cost is high. In addition, the installation of the ball head in the shoe structure is complicated. Contents of the invention [0003...
