Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail:
Referring to Fig. 1 to Fig. 5, a kind of tunnel grouting chassis brake unit, this device is made up of main breaking zone device and complemental brake system. Main breaking zone device includes tire support 1, wheel shaft 2, braked wheel 3, tire 4, electric hydraulic pump 5, dowel steel 6, tripping spring 7, band-type brake 8. Chassis top weight reaches on tire 4 through tire support 1-wheel shaft 2; Tripping spring 7 is Pre strained state when electric hydraulic pump 5 does not work, braked wheel 3 held tightly by band-type brake 8 now, frictional force will be produced between band-type brake 8 and braked wheel 3, restriction braked wheel 3 rotates, owing to being connected by wheel shaft 2 between braked wheel 3 with tire 4, so when braked wheel 3 does not rotate, tire 4 also can not rotate, now produce sliding friction between tire 4 and ground, it is achieved braking. When electric hydraulic pump 5 live line work, electric hydraulic pump 5 piston rod rises, and overcomes the pretightning force jack-up dowel steel 6 of tripping spring 7, produces gap, release braking between band-type brake 8 and braked wheel 3. Main breaking zone device can provide brake force when chassis is static, release braking in chassis traveling process. Complemental brake system includes fixing truss 9, rotation dish 10, swivel bearing 11, force transmission shaft 12, axle sleeve 13, brake block 14, and fixing truss 9 connects chassis and complemental brake system, is used for transmitting brake force; Force transmission shaft 12 is limited in axle sleeve 13, and its top is connected with rotation dish 10, and bottom is connected with brake block 14; Rotation dish 10 is connected with fixing truss 9 down through swivel bearing 11, and rotation dish 10 inwall is provided with the screw thread matched with force transmission shaft 12 outer wall; When rotating rotation dish 10, moment of torsion is transferred to force transmission shaft 12 by screw thread, and force transmission shaft 12 is thus raised or lowered; When force transmission shaft 12 is lowered, the pressure between brake block 14 and ground increases, and brake force improves; Otherwise, when force transmission shaft 12 is elevated, brake force reduces. This utility model can provide bigger brake force and brake force adjustable, can either guarantee safety during cementing operations under resting state, can control again the gait of march of chassis, it is ensured that the safety and efficiency of tunnel steep slope section cementing operations; And this brake device structure simply easily adjusts, it is possible to adapt to different road pavement form, the tire support 1 in main breaking zone device all can change according to tunnel road pavement form with the fixing truss 9 in complemental brake system, makes brake unit reach best on-position.
Below operating process of the present utility model is described in detail:
As depicted in figs. 1 and 2, active brake unit of the present utility model includes tire support 1, wheel shaft 2, braked wheel 3, tire 4, electric hydraulic pump 5, dowel steel 6, tripping spring 7, band-type brake 8. Tire support 1 can adopt shaped steel, and type steel model is determined according to top load-carrying; Tripping spring 7 is initially extended state, and when electric hydraulic pump 5 does not work, tripping spring 7 initial tensile force is reached band-type brake 8 by dowel steel 6, makes band-type brake 8 produce frictional force with braked wheel 3 close contact. Owing to not relatively rotating between wheel shaft 2 and tire 4, the frictional force between band-type brake 8 and braked wheel 3 can be passed through tire 4 and reach ground, and then produces brake force. When needs release braking, operating electric hydraulic pump 5, overcome tripping spring 7 elastic force jack-up dowel steel 6, make the generation gap between band-type brake 8 and braked wheel 3, braked wheel 3 is that is free to rotate.
As shown in figs. 3 and 4, complemental brake system of the present utility model includes fixing truss 9, rotation dish 10, swivel bearing 11, force transmission shaft 12, axle sleeve 13, brake block 14. When main breaking zone device can not meet brake request, it is necessary to adopt complemental brake system to increase brake force. Fixing truss 9 adopts steel welding knot to form, and shaped steel type is determined according to design brake force size. Rotation dish 10 periphery is round steel pipe, and steel pipe and inside can adopt reinforcing bar or fastener for connection. Swivel bearing 11 is in order to reduce the frictional force between rotation dish 10 and fixing truss 9. Having the screw thread matched with rotation dish 10 outside force transmission shaft 12, bottom is connected with brake block 14; Brake block 14 top is iron block, in order to increase the stiffness of brake block; Bottom is block rubber, with by the frictional force increased between brake block and ground and protect ground. When needs apply brake force, rotating rotation dish 10 counterclockwise, under the effect of rotation dish 10 and force transmission shaft 12 screw thread, force transmission shaft 12 will move down along axle sleeve 13, and the pressure between brake block 14 and ground increases, and brake force increases therewith. During as reduced brake force, turn clockwise rotation dish 10, and under the effect of rotation dish 10 and force transmission shaft 12 screw thread, force transmission shaft 12 will move up along axle sleeve 13, and the pressure between brake block 14 and ground reduces, and brake force reduces therewith.
When carrying out cementing operations on abrupt slope, owing to serosity and grouting equipment quality are relatively big, meanwhile, in hole, there may exist the wet and slippery situation in ground, when main breaking zone device can not reach braking effect, complemental brake system can be used to increase brake force simultaneously; When the chassis that is in the milk is walked on abrupt slope, for control station car gait of march, now adopt auxiliary braking regulating brake force, make chassis safety at the uniform velocity travel.
