Abstract

The invention discloses a movable belt adjusting device. A stress rod piece is fixed on a belt frame; a balance rod piece is rotationally mounted on the stress rod piece; two balance auxiliary piecesare mounted at the front and back ends of the balance rod piece; a belt penetrates through the balance auxiliary pieces at the front and back ends in sequence in a bonding mode, so that the balance auxiliary pieces at the front and back ends are staggered corresponding to the upper and lower positions of the belt; one side of a first adjusting pull rood is connected with the balance rod piece; oneside of a second adjusting pull rod is connected with a scraper; the other sides of the two adjusting pull rods penetrate through a belt frame, and adjusting limiting pieces are arranged on the sides; two adjusting springs sleeve the two adjusting pull rods; and the two ends of the adjusting springs are ejected against the belt frame and the adjusting limiting pieces. The device can inhibit flexible deformation and operation vibration of the belt in the operation process, prevents the wear acceleration caused by nonuniform stress of the scraper, and guarantees the scraping effect.

Description

technical field

[0001] The invention relates to the field of shield tunnel construction, in particular to a movable belt adjustment device used for excavation by belt conveyors of earth pressure balance shield machines. Background technique

[0002] Conveyor belts are widely used in the market. Generally, a driving wheel drives a belt to rotate on a row of rollers, and the tension of the belt is adjusted by changing the position of the driving wheel or the driven wheel. In the shield industry, the belt used by the shield machine is generally long and is a flexible strip, which is supported by a row of rollers for operation under its own weight. The change in the amount of muck loaded on the belt during operation will change the tightness of the belt. When the belt is prone to flexible deformation and vibration. Belt conveyors generally use 2-3 mud scrapers at the driving wheel. Under the vibration and gravity of the belt, the mud scrapers are prone to uneven force, resultin...

Embodiment Construction

[0018] The present invention will be further described below in combination with specific embodiments and accompanying drawings.

[0019] Such as figure 1 , 2 As shown, a movable belt adjustment device includes a belt frame 1, a belt 2, a force rod 3, a balance rod 4, a balance auxiliary member 5, a first adjustment pull rod 6, a first adjustment spring 62 and a first adjustment spring 62. Adjust the limiting member 63 , the second adjusting pull rod 7 , the second adjusting spring 72 , the second adjusting limiting member 73 , the mud scraper 8 and the flushing pipeline 9 .

[0020] The two stressed rods 3 are fixed on the left and right sides of the belt frame 1 with the same height and symmetrical positions, and are located on the lower side of the belt frame 1 .

[0021] The balance rod 4 is a two-section arc structure, which is formed by connecting one large arc and one small arc. The radius of the large arc is 4-6 times that of the small arc, and the arc length of the ...
