[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figures 1 to 3 As shown, an adjustable friction wheel driving device for a concrete self-insulating block conveyor line comprises a support seat 1, on which a driving motor 2 and a reducer 3 are arranged, and the reducer 3 is connected to a friction wheel 4. The support seat 1 comprises an upper seat plate 101 and a lower seat plate 102, and one distal end of the upper seat plate 101 and the lower seat plate 102 are hingedly connected, and a compression spring assembly 5 is arranged at the other distal end; the compression spring assembly 5 comprises a guide screw 501 and a compression spring 502, one end of the guide screw 501 is fixedly connected to the lower seat plate 102 by a nut, and the other end is arranged on the upper seat plate 101. The guide hole of the seat plate 101 is vertically penetrated and connected to the upper seat plate 101, and the compression spring 502 is penetrated on the guide screw 501 between the upper seat plate 101 and the lower seat plate 102, and the diameter of the guide hole is larger than the diameter of the guide screw 501; an elastic airbag 6 is arranged between the upper seat plate 101 and the lower seat plate 102, and the elastic airbag 6 is arranged on the combined center of gravity axis of the upper seat plate 102 and the object carried thereon, and the elastic airbag 6 includes an air inlet and an air outlet, and the air inlet is connected to the air station; proximity switches are respectively arranged at the front and rear ends of the friction wheel 4.

[0018] This embodiment increases the load-bearing arm, improves the elastic load ratio of the spring, increases the service life of the spring, and reduces the frequency of spring replacement by arranging the compression spring assembly at the far end of the upper seat plate; at the same time, this application arranges an elastic airbag on the axis of the combined center of gravity of the upper seat plate and the load on it, and a proximity switch is installed in front and behind the friction wheel. When the approach of the mold box is not sensed, the air pressure of the elastic airbag is increased by regulating the air pressure of the elastic airbag to directly bear the load and reduce the pressure on the spring; when the approach of the mold box is sensed, it automatically starts to operate and reduces the air pressure of the airbag. The pressing force generated by the compression of the spring is converted into friction force through the friction wheel to drive the mold forward, increasing the reliance on the elasticity of the spring. At the same time, the low-pressure airbag increases elasticity and shares the force of the spring; when the mold box is sensed to be driven out by the proximity switch, it automatically stops rotating and the airbag is inflated and pressurized again. Running at this rhythm greatly reduces the number of load cycles, load duration, load frequency and load size of the compression spring assembly, thereby greatly reducing the fatigue accumulation of the spring material, slowing down the elastic transformation of the spring, thereby extending the life of the spring, extending the effective and smooth operation time of the production line mold trolley, and improving production efficiency.

[0019] In other specific embodiments, a first screw adjustment nut 503 is provided on the guide screw 501 on the upper part of the upper seat plate 101. A first adjustment sleeve 504 is passed through the guide screw 501 above the first screw adjustment nut 503, and a first adjustment sleeve adjustment nut 505 is provided above the first adjustment sleeve 504. Regularly check the wear of the friction wheel. If it is slightly worn, first adjust the first adjustment sleeve adjustment nut 505 of the first adjustment sleeve 504 downward to raise its position so that it can continue to be used. If it is severely worn, replace it in time. Regularly check whether the friction wheel spring is loose and whether the spring elasticity is too small. If it is slightly worn, first adjust the first adjustment sleeve adjustment nut 505 of the first adjustment sleeve 504 downward and adjust the first screw adjustment nut 503 downward to clamp the spring. If it is severely worn, replace it in time.

[0020] In other specific embodiments, adjusting screws 7 are provided at both ends of the lower seat plate 102, the lower part of the adjusting screws 7 is connected to a mounting seat, and a second screw adjusting nut 701 is provided on the adjusting screws 7 between the mounting seat and the lower seat plate 102. A second adjusting sleeve 702 is passed through the adjusting screw 7 below the second screw adjusting nut 701, and a second adjusting sleeve adjusting nut 703 is provided below the second adjusting sleeve 702. During regular inspections, if the friction wheel rubber is worn or the spring height is too low, resulting in insufficient clamping force, the second screw adjusting nut 701 can be adjusted upwards, and the second adjusting sleeve 702 and the second adjusting sleeve adjusting nut 703 can be adjusted upwards at the same time, thereby raising the lower seat plate 102 and the friction wheel 4, thereby reducing the replacement frequency of the spring assembly, increasing the service life of the spring, and improving production efficiency.
