Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
An embodiment of a mechanism for folding a belt of a mobile crusher and a bracket into three sections as shown in fig. 1 and 2 comprises a bracket 1, a hydraulic cylinder 2, a plurality of carrier rollers 3 connected with the bracket 1, and a belt (not shown) sleeved on the bracket through the carrier rollers 3.
The bracket 1 comprises a bracket front section 11, a bracket middle section 12 hinged with the bracket front section 11 and a bracket rear section 13 hinged with the bracket middle section 12. The hydraulic cylinder 2 includes a cylinder rod 21 and a cylinder tail 22 connected to the cylinder rod 21. The piston rod 21 of the hydraulic cylinder is hinged with the front section 11 of the bracket, and the tailstock 22 of the hydraulic cylinder is hinged with the rear section 13 of the bracket.
The inner walls of the two sides of the tail end of the front support section 11 are respectively welded with 1 first limiting plate 4, and the inner walls of the two sides of the head end of the rear support section 13 are respectively welded with 1 second limiting plate 5. The shapes of the first limiting plate 4 and the second limiting plate 5 and the shape of the bracket middle section 12 are matched to realize clamping connection, so that the bracket 1 is reliably limited to drive the belt to contract.
In this embodiment, the both sides inner wall in support middle section is equipped with spacing 6 respectively, and spacing 6 is bar structure, extends along support middle section length direction. When folding, 6 head ends of spacing strip and the cooperation of first limiting plate 4 realize spacing to first limiting plate 4, and 6 tail ends of spacing strip and the cooperation of second limiting plate 5 realize spacing to second limiting plate 5.
As a further explanation of the present embodiment, the operation flow will now be described: when the belt is folded, the piston rod 21 of the hydraulic cylinder contracts relative to the tailstock 22 of the hydraulic cylinder to drive the front section of the belt to be folded upwards, and the front section 11 of the bracket rotates by 90 degrees until the limiting plate 4 is superposed with the limiting surface of the middle section 12 of the bracket, so that the front section 11 of the bracket and the front section of the belt stop rotating; the piston rod 21 of the hydraulic cylinder continuously contracts relative to the tailstock 22 of the hydraulic cylinder to drive the middle section of the belt to be continuously folded, the middle section of the belt starts to be folded, the front section 11 of the bracket and the middle section 12 of the bracket are relatively static at the moment, and when the middle section 12 of the bracket rotates to be vertical to the horizontal ground, the limiting plate 4 of the rear section 13 of the bracket prevents the middle section 12 of the bracket from continuously rotating; at this time, the cylinder rod 21 stops contracting relative to the cylinder tailstock 22, and the front bracket section 11 horizontally abuts against the crusher shield to fold the belt into three sections.
In the embodiment, the folding belt firstly rotates the front section 11 of the bracket and then rotates the middle section 12 of the bracket to realize folding; limiting plates are respectively designed at the tail end of the support front section 11 and the head end of the support rear section 13, so that the relative support middle section 12 is limited, namely the support middle section 12 is limited with the support front section 11, the support front section 11 is limited to rotate by 90 degrees, and the support middle section 12 is limited relative to the support rear section 13 until the support middle section 12 rotates to a vertical position.
The embodiment provides a reliable, high-efficient, the economic utilization double hydraulic cylinder drive, with the mechanism of breaker belt folding into three-section, through design limiting plate shape ingeniously, pneumatic cylinder mounting means, high-efficient, reliably fold the belt into three-section. The occupied area of the mobile crusher during parking is reduced, the stability of the support of the crusher in the moving process is improved, and the requirement that the support is too long to extend out to meet the requirement of a wide road surface in the moving process is avoided. The occupied space of the crusher belt is greatly reduced, the folding efficiency of the belt is improved, and the cost of folding the belt into three sections is reduced.
Other structures of this embodiment are seen in the prior art.
The present invention is not limited to the above embodiment, and various modifications and variations of the present invention are also intended to be included within the scope of the claims and the equivalent technical scope of the present invention if they do not depart from the spirit and scope of the present invention.
