Description

A fan-shaped shifting belt conveyor tail rotary station Technical Field

[0001] This invention relates to the field of belt conveyor technology for bulk material conveying systems, specifically to a tail rotary station, and more particularly to a fan-shaped shifting belt conveyor tail rotary station. Background Technology

[0002] The fan-shaped shifting belt conveyor is mainly used in open-pit mining. Its basic operation involves the overburden transported by the shifting belt conveyor being fed by unloading cars working back and forth on the conveyor to a dumping machine for disposal. Once the dumping machine is full of overburden along the conveyor path, the shifting belt conveyor rotates around its tail rotation center, advancing in a fan shape, and then moves to the next dumping line location to transport the overburden. Existing tail rotation stations have the following drawbacks:

[0003] 1. Material handling is restricted when rotating at the center and tail of the machine station;

[0004] 2. Existing tail-end rotary stations all use a sunken box design, resulting in uneven stress distribution.

[0005] 3. When there is no material, the upper turntable will be unbalanced.

[0006] 4. Current drives all use head drives, which require excessively long cables.

[0007] 5. The tail rotary station does not have a conveyor belt tensioning function, and tensioning is entirely dependent on the unloading car, which increases the weight of the unloading car.

[0008] 6. The drum is very difficult to repair.

[0009] Therefore, developing a fan-shaped shifting belt conveyor tail rotary station is an urgent new problem to be solved. Summary of the Invention

[0010] To address the aforementioned technical issues, a fan-shaped shifting belt conveyor tail rotary station is provided.

[0011] The technical means employed in this invention are as follows:

[0012] A fan-shaped movable belt conveyor tail rotary station includes a base, which is fixedly connected to a concrete foundation; a shaft is fixed at the center of the base, and an upper rotating platform is arranged on the base. The upper rotating platform is rotatably connected to the base through the shaft, and the base is fixedly connected to the upper rotating platform by multiple bolts.

[0013] An integrated tailstock of idler rollers is installed on the upper rotating platform; before rotating the integrated tailstock of idler rollers, the bolts between the base and the upper rotating platform are removed, and the bolts are reconnected after rotating to the designated position;

[0014] A movable belt conveyor is installed on the integrated tail frame of the idler rollers; the movable belt conveyor includes a conveyor belt, and a fixed-point rotating receiving port is fixed above the integrated tail frame of the idler rollers. The axis of the discharge end of the fixed-point rotating receiving port is coaxial with the shaft. The material falling from the fixed-point rotating receiving port falls into the conveyor belt and is carried away by the conveyor belt.

[0015] The upper rotating platform is detachably equipped with a counterweight at one end of the conveyor belt in the transmission direction, so that when the tail rotating station stops and there is no material, the center of gravity of the tail rotating station is located at the axis.

[0016] Preferably, the movable belt conveyor further includes a roller assembly installed on top of the roller drum integrated tailstock, the roller assembly being used to support the conveyor belt.

[0017] Preferably, the shifting belt conveyor further includes two drive rollers and two redirecting rollers; the two drive rollers are respectively connected to two drive units, which are mounted on the upper rotating platform;

[0018] One end of the conveyor belt passes sequentially through the first redirecting roller, the first driving roller, the second driving roller, and the second redirecting roller to form a closed-loop transmission. The axial ends of the driving roller and the redirecting roller are respectively mounted on the column of the idler roller integrated tail frame through roller maintenance supports, and the roller maintenance supports are bolted to the idler roller integrated tail frame.

[0019] Preferably, the tail rotary station further includes a roller maintenance base detachably connected to the upper rotary platform. The roller maintenance base is equipped with a roller maintenance track frame that slides with its track. During maintenance, the roller maintenance base and the roller maintenance track frame are installed on the upper rotary platform, the bolts between the roller maintenance support and the idler roller integrated tail frame are removed, so that the roller maintenance track frame can support the drive roller or the redirecting roller, and then be pulled out.

[0020] Preferably, the two drive units are located on opposite sides of the transmission belt.

[0021] Preferably, the movable belt conveyor further includes a tensioning roller, which is arranged on top of the integrated tail frame of the idler rollers and located at the end away from the conveyor belt's transport direction. The bearing seats at both ends of the tensioning roller are slidably fitted to the top of the integrated tail frame of the idler rollers. A tensioning crossbeam is arranged above the bearing seats at both ends of the tensioning roller and is slidably fitted thereto. The tensioning crossbeam is connected to the integrated tail frame of the idler rollers by bolts. One end of a steel wire rope is connected to the bearing seat of the tensioning roller. The other end of the steel wire rope is redirected by a guide pulley group installed at the end of the integrated tail frame of the idler rollers and then connected to an elastic tensioning counterweight plate, so that the elastic tensioning counterweight plate is suspended on the integrated tail frame of the idler rollers. The elastic tensioning counterweight plate applies a pulling force to the tensioning roller towards the end away from the conveyor belt's transport direction, thereby tensioning the conveyor belt.

[0022] During maintenance, remove the bolts between the tension beam and the integrated tail frame of the idler roller, and lift the tension roller.

[0023] Preferably, the tail rotation station is located inside the foundation pit, the concrete foundation is fixed to the bottom of the foundation pit, and the foundation pit allows the idler roller integrated tail frame to rotate within the foundation pit.

[0024] Preferably, a guide trough is installed on the top of the integrated tailstock of the idler roller at the unloading end of the fixed-point rotating receiving port. The guide trough is located on both sides of the conveyor belt, and the receiving port is connected to the guide trough by bolts.

[0025] Preferably, the fixed-point rotating receiving port has two flanges arranged vertically, and a rubber curtain is arranged at the flange. The circular chute for receiving material is vertically inserted into the flange, and the two rubber curtains seal the connection.

[0026] Compared with the prior art, the present invention has the following advantages:

[0027] 1. The fixed-point rotating receiving port has its receiving center coincided with the rotation center of the tail station, achieving the purpose of fixed-point material receiving. At the same time, the receiving port is connected by two circular flanges, with upper and lower double-layer rubber curtains. The circular chute of the incoming material is inserted vertically into the flanges and sealed by the upper and lower rubber curtains, which plays a role in dust suppression during unloading.

[0028] 2. The drive units are installed on both sides of the conveyor belt, allowing the upper rotating platform to achieve gravity balance on both sides of the conveyor belt. Simultaneously, the dual-drive system effectively reduces the strength of the conveyor belt and lowers its cost. The drive units are all placed on the tail station, saving the length of cable required for head-drive systems.

[0029] 3. The specifications of the elastic tensioning counterweight plate are comprehensively determined based on calculations of the elastic tension of the conveyor belt under various working conditions of the moving belt conveyor, while the permanent tensioning is set on the unloading car. The counterweight tensioning method has a fast response, and this method of setting the tensioning on different equipment greatly shortens the total tensioning stroke on the unloading car, effectively reducing the weight of the steel structure of the unloading car.

[0030] 4. The base is directly connected to the concrete foundation pit, and the concrete foundation is set in a concrete foundation pit. The depth of the foundation pit must ensure that the roller and drum integrated tail frame can be moved and rotated outside the pit. The range of the foundation pit must take into account the lifting space when maintaining the tail station. The foundation pit must be able to withstand the horizontal tension of the conveyor belt within the range of the moving and rotating angle. This type of foundation pit concrete foundation can eliminate the disadvantage of uneven stress during the relocation of the buried caisson.

[0031] 5. The upper turntable has rotation and counterweight adjustment functions, and can be rotated and moved with the addition of counterweight when there is no material.

[0032] 6. During rotation, the movable belt conveyor stops. At this time, there is no material on the conveyor belt. Place counterweights on the upper rotating platform to balance the weight of the material and ensure that the center of gravity of the tail station remains unchanged when there is no material. Drag the integrated tail frame of the idler rollers to rotate it around the shaft on the base to the next working position, and reconnect the bolts between the base and the upper rotating platform. During maintenance, release the elastic tensioning hammer plate on the tail station and the tensioning device on the unloading car to loosen the conveyor belt and facilitate its removal from the rollers. Loosen the bolts between the tensioning beam and the integrated tail frame of the idler rollers, remove the tensioning beam, and the tensioned rollers can be lifted and transported away for maintenance. Loosen the bolts fixing the roller maintenance support to the integrated tail frame of the idler rollers, and at the same time install the roller maintenance base on the upper rotating platform. Overlay the roller maintenance track frame on the roller maintenance base. The rollers and roller maintenance supports can be transported laterally out of the main structure through the maintenance track frame, and then lifted and transported away for maintenance.

[0033] Based on the above reasons, this invention can be widely promoted in fields such as the tail rotary station of a moving belt conveyor. Attached Figure Description
