Abstract

The invention discloses a double-rope dual-connection mechanism for an automatic telescopic sealing-tape machine structure. The mechanism comprises an electric winch, two upper rope outlet steel wireropes, two lower rope outlet steel wire ropes, a supporting pulley block, an upper rope outlet steel wire rope balance mechanism, a lower rope outlet steel wire rope balance mechanism, a riding wheelset and a redirection pulley block. The two upper rope outlet steel wire ropes are connected with the electric winch, the two lower rope outlet steel wire ropes are connected with the electric winch,the two upper rope outlet steel wire ropes are connected with the supporting pulley block, the upper rope outlet steel wire rope balance mechanism is connected with the supporting pulley block, the two lower rope outlet steel wire ropes are connected with the redirection pulley block, and the redirection pulley block is connected with the lower rope outlet steel wire rope balance mechanism throughthe riding wheel set. According to the mechanism, when the requirements for the stockyard storage capacity and the material blending effect are high, the mechanism can be applied to a traditional stacker, the storage utilization rate of a fixed stockyard can reach the maximum, full-section material taking can be achieved during material taking, the optimal blending effect is achieved, the operation cost of equipment is reduced, and the mechanism is applied to the technical fields of ports, strip mines and coal mines.

Description

technical field [0001] The invention relates to a double-rope double-connection mechanism used in the structure of an automatic retractable belt conveyor in the technical fields of ports, open-pit mines and coal mines. Background technique [0002] At present, on the stacker equipment in the stockyards of ports, open-pit mines, coal mines and other industries, the requirements for the storage capacity of the stockyard and the mixing effect of materials are constantly improving. The traditional stocker has a fixed cantilever length Therefore, the shape and cross-section of the stockpile produced by the equipment can only be conical, and the width and height of the stockpile are required to be fixed values, so the storage rate that can be used by the stockyard is very low; at the same time, when the material mixing effect is required When it is high, the traditional stacker can only use the method of reciprocating walking to improve the mixing effect of the material. This meth...

[0002] At present, on the stacker equipment in the stockyards of ports, open-pit mines, coal mines and other industries, the requirements for the storage capacity of the stockyard and the mixing effect of materials are constantly improving. The traditional stocker has a fixed cantilever length Therefore, the shape and cross-section of the stockpile produced by the equipment can only be conical, and the width and height of the stockpile are required to be fixed values, so the storage rate that can be used by the stockyard is very low; at the same time, when the material mixing effect is required When it is high, the traditional stacker can only use the method of reciprocating walking to improve the mixing effect of the material. This method does not have a high mixing effect on the material, and it needs to consume a lot of kinetic energy and a lot of time to achieve it. , thus increasing the operating cost of the equipment

[0003] attached Figure 7 For the conventional stockers described in , the length of the cantilever of this type of equipment is fixed, and only a herringbone stockpile can be formed when stockpiling. ; and when the material mixing effect is high, the traditional stacker can only use the reciprocating walking stacking method to improve the material mixing effect. The realization of this method requires a lot of kinetic energy and a lot of time. Therefore, the operating cost of the equipment will increase a lot

[0004] In view of the above reasons, people have tried to use the gear and rack mechanism to realize the belt conveyor on the cantilever of the telescopic stacker to achieve the purpose of improving the stacking efficiency and increasing the storage rate of the stockyard. In the patent of Telescopic Belt Conveyor (Patent No. 201621019150.8), the mechanism of gear and rack is used to adjust the conveying distance of the belt conveyor, but this rack and pinion mechanism requires high manufacturing precision and installation precision , and require the gear and the rack to have the same backlash at any point in the entire telescopic distance to ensure correct meshing, prevent vibration, and ensure the smooth operation of the equipment, which requires the inner arm of the embedded rack The frame must have high straightness, which is difficult to guarantee for large structural parts with large deformation

Moreover, this mechanism is not suitable for materials that are prone to dust, because dust is easy to enter the tooth grooves of the gear and rack, requiring frequent maintenance and cleaning, while reducing the service life of the gear and rack
