Problems solved by technology
[0003] The existing hydraulic stop wheel device has the following disadvantages: the hydraulic components require high manufacturing precision, high assembly requirements, and strict maintenance during use; the hydraulic stop wheel device uses hydraulic oil with a pressure of about 15MPa as the medium to realize the up and down of the stop wheel Sliding and swimming, so the hydraulic oil is prone to leakage; the hydraulic stop wheel device needs to be equipped with a hydraulic station with a pressure of about 15MPa
Greatly increased the cost of equipment; faults are not easy to check and eliminate

The invention discloses a spring thrust blocking-wheel device. The spring thrust blocking-wheel device comprises a first support, a second support, a blocking wheel slide seat arranged between the first support and the second support, a blocking wheel fixed to the blocking wheel slide seat, at least one guide rod, wherein the first support and the second support are fixedly installed on a base and are connected through two guide shafts, the blocking wheel slide seat penetrates through the guide shafts, one end of the guide rod is fixed to the blocking wheel slide seat, the other end of the guide rod movably penetrates through the first support, a spring penetrates through the guide rod, and two ends of the spring are respectively fixed to the blocking wheel slide seat and the first support. The spring thrust blocking-wheel device is simple in structure, easy to manufacture and convenient to maintain and is suitable for a rotating body device, and device cost is greatly reduced.
Description
technical field [0001] The invention relates to a revolving body device, in particular to a spring thrust retaining wheel device. Background technique [0002] Rotary equipment such as rotary kiln, rotary dryer and rotary cooler are commonly used in building materials industry, chemical industry and metallurgical industry. The cylinder of the above equipment is installed obliquely. Due to the axial force generated by self-weight and friction, and due to installation or deformation, The axes of the rolling ring and the supporting wheel are not parallel to generate additional axial force, and the large and heavy cylinder is difficult to fix its axial position, so it should be allowed to move repeatedly in the axial direction. In order to make the working surfaces of the supporting rollers and rolling rings with different widths wear evenly, the cylinder is also required to be able to move axially. The retaining wheel plays the role of restricting the axial movement of the cyl...
