Specific embodiment

Combined with specific embodiments below and attached drawing the invention will be further described.

As shown in Figure 1, 2, a kind of active belt regulating device, including belt frame 1, belt 2, stressed member 3, balance Rod piece 4, balance auxiliary member 5, the first adjusting yoke 6, the first adjustment spring 62 and first adjust locating part 63, the second adjusting yoke 7, the second adjustment spring 72, second adjusts locating part 73, cleaning shoe 8 and flushing pipeline 9.

Two stressed members 3 are fixed on the left and right sides of belt frame 1 to highly consistent and positional symmetry respectively, and are located at The downside of belt frame 1.

Balance bar 4 is two sections of arcuate structures, is connected by small one and large one two sections of arcs and is formed, and the radius of big arc is small arc 4-6 times of shape radius, the arc length of big arc are 1.5-2.5 times of small arc arc length.Two balance bars 4 are distinguished by rotational pin It is installed in rotation on the stressed member 3 of the left and right sides, positional symmetry between two balance bars 4, rotational installation point is located at The point of interface of size arc.

Two balance auxiliary members 5 are idler wheel, and two balance auxiliary members 5 are pacified respectively by the balance bar 4 of the left and right sides Mounted in the rear and front end of balance bar 4.

Belt 2 successively snugly threads through the balance auxiliary member 5 of rear and front end, keeps the balance auxiliary member 5 of rear and front end opposite It is staggered in 2 upper and lower position of belt.

The side of two first adjusting yokes 6 is connected at left and right sides of the rear end of balance bar 4, and the other side penetrates through Belt frame 1, and on the side for penetrate through belt frame 1 be equipped with thread segment 61, first adjust locating part 63 be nut, first 63 position of locating part is adjusted adjustably to be mounted on thread segment 61, the first adjustment spring 62 is sleeved on the first adjusting yoke 6, and Both ends press against belt frame 1 and first respectively and adjust on locating part 63.Locating part 63 is adjusted in thread segment by changing first Position on 61 makes the Level Change of the first adjusting yoke 6, so as to adjust the elasticity between balance auxiliary member 5 and belt 2.

The side of two second adjusting yokes 7 is connect with cleaning shoe 8, and cleaning shoe 8 is made to be tightly attached to the downside of belt 2, another Side penetrates through belt frame 1, and thread segment 71 is provided on the side for penetrating through belt frame 1, and second adjusts locating part 73 For nut, the second adjusting 73 position of locating part is adjustably mounted on thread segment 71, and the second adjustment spring 72 is sleeved on the second tune It saves on pull rod 7, and both ends press against belt frame 1 and second respectively and adjust on locating part 73.Limit is adjusted by changing second Position of the part 73 on thread segment 71 makes the Level Change of the second adjusting yoke 7, so as to adjust between cleaning shoe 8 and belt 2 Elasticity.

Flushing pipeline 9 is fixed on the lower section of belt 2 by the stressed member 3 of the left and right sides, and sets along 2 width direction of belt It sets, flushing pipeline 9 is equipped with the fan douche spray head towards belt 2, for being rinsed to belt 2.

In the present apparatus, balance auxiliary member 5 is alternately close together with 2 upper and lower position of belt, in 6 He of the first adjusting yoke Under the cooperation of first adjustment spring 62, balance auxiliary member 5 is able to suppress the dough deformation in the process of running of belt 2 and operating Vibration, so that 8 unbalance stress of cleaning shoe be avoided to lead to accelerated wear test, cleaning shoe 8 after use prolong by even wearing, service life It is long, in addition, under the cooperation of the second adjusting yoke 7 and the second adjustment spring 72, the energy in the operational process of belt 2 of cleaning shoe 8 Enough dynamic adjustment position, even if scraping mud in clay stratum complicated and changeable or in the case where encountering tough dregs Plate 8 also can keep fitting closely with belt 2, and dregs scraped clean to fully play the effect of cleaning shoe 8, has 2 surface of belt is cleaned up to effect, wears, reduces scaling-off in tunnel after preventing belt feeder deposition from belt roller being caused to wrap up Cleaning labour and time cost, it is clean and tidy to realize tunnel, improves constructing tunnel image and has saved a large amount of durations, and improves 2 machine runnability of belt has ensured the civilized construction and equipment operational safety of shield tunnel.

In other embodiments, in two balance auxiliary members, one of them is idler wheel, another is cleaning shoe, and idler wheel is tight It is attached to the upside of belt, cleaning shoe is tightly attached to the downside of belt.By setting cleaning shoe, energy for one of balance auxiliary member It is enough that more efficiently the dregs of a small amount of remnants on belt is struck off.
