Description

Technical Field

[0001] The invention relates to the technical field of hydraulic systems, and in particular to a bottom adjusting cylinder device at the tail of a belt conveyor. Background Art

[0002] During the underground mining process in coal mines, the tail of the belt conveyor needs to be moved forward a certain distance each shift for follow-up. Extending the belt conveyor in a narrow tunnel will affect the excavation speed. Therefore, it is necessary to add a fast-moving self-moving tail device to the tail of the original belt conveyor to form a self-moving belt conveyor to facilitate movement.

[0003] The self-moving tail device is mainly composed of various types of cylinders, including lifting cylinders for lifting devices and cylinders for pushing devices to move horizontally. Multiple cylinders work together to push the device to move. The self-moving belt conveyor tail carries the head drive part of the transfer machine, which is relatively bulky. Due to the uneven bottom plate of the transport chute roadway, the base in the cylinder cannot adapt to the ups and downs of the ground. The resistance is large during the pushing of the tail, and the belt conveyor tail drills the bottom seriously. After the tail is pulled and moved, a lot of coal flows at the bottom of the belt, which easily causes the belt to be blocked or broken. Sometimes, the cylinder base slides sideways due to the inclined ground, which affects the contact force with the ground and causes insufficient thrust. In addition, there is a height difference on the ground and there are local depressions. Multiple lifting cylinders on the same side are generally controlled and operated synchronously. When encountering such terrain, the bottom of some cylinders may not be well contacted with the ground, resulting in suspension. The forces on each cylinder are different, which increases the working pressure of the cylinder and may even cause the entire conveyor to become unstable and collapse.

[0004] Therefore, due to the uneven bottom plate of the transport chute, the base of the oil cylinder cannot adapt to the ups and downs of the ground. The resistance in the process of pushing the tail of the machine is relatively large, and it is easy to drill the bottom seriously and cause coal gushing, resulting in the obstruction or breakage of the belt. The oil cylinder base will also slide sideways due to the inclination of the ground, and the grip is insufficient and the contact with the ground is lost, resulting in insufficient thrust. In addition, there is a height difference on the ground and there are local depressions. Multiple lifting cylinders on the same side are generally controlled and operated synchronously. When encountering such terrain, the bottom of some oil cylinders may not be well in contact with the ground and become suspended in the air, and the force on each cylinder In order to solve the problem that increasing the working pressure of the cylinder may even cause the entire conveyor to become unstable and collapse, a bottom adjusting cylinder device can be designed for the tail of a belt conveyor. According to the complex terrain of the ground where each cylinder body is located, the supporting chassis can be adjusted separately to rotate parallel to the ground, and the cylinder body can be started and controlled separately to work, and the plug at the bottom of the lifting ring can be pushed into the ground, so as to independently control the operation of each cylinder body and the mounting parts, so that the supporting chassis at the bottom of each cylinder body can adapt to the undulations, depressions and height differences of the corresponding surface, thereby improving the stability of the device during movement and effectively avoiding the instability and collapse of the machine body. Summary of the invention

[0005] In order to overcome the problem that the base of the oil cylinder cannot adapt to the undulations of the ground due to the uneven bottom plate of the transport chute, the resistance in the process of pushing the tail of the machine is large, and it is easy to drill the bottom seriously and cause coal gushing, resulting in the obstruction or breakage of the belt. The base of the oil cylinder may slide sideways due to the inclination of the ground, and the grip is insufficient and the contact with the ground is lost, resulting in insufficient thrust. In addition, there is a height difference in the ground and local depressions. Multiple lifting cylinders on the same side are generally controlled and operated synchronously. When encountering such terrain, the bottom of some oil cylinders may not be well in contact with the ground and become suspended in the air.

[0025] Through the above steps, multiple cylinder bodies 1 are evenly installed on both sides of the machine body, and the top of the large piston rod of the cylinder body 1 is installed with the machine body. When in use, according to the inclination of the ground on which each cylinder body 1 is located, the U-shaped frame 3 is driven to rotate in the opposite direction through the fixing seat 4, so as to adjust the supporting chassis 2 to be parallel to the ground, and then the independent controller 12 controls the starting motor 29 to reciprocate and drive the threaded rod 13 to rotate, and the threaded rod 13 drives the L-shaped support plate 14 to reciprocate and rise and fall, so that the small piston rod on the cylinder body 1 is reciprocatedly pressed by the push plate 15 to realize the starting work of the cylinder body 1, and the cylinder body 1 pushes the supporting chassis 2 in the opposite direction to move downward and contact the ground, and then The four small electric push rods 6 are controlled and started by the independent controller 12 to push the lifting ring 7 downward, and the plug posts 8 at the bottom of the lifting ring 7 are inserted downward into the ground, thereby enhancing the contact grip between the supporting chassis 2 and the ground and preventing slipping. Thus, by controlling the independent operation of each oil cylinder body 1 and the mounting components, the supporting chassis 2 at the bottom of each oil cylinder body 1 can be adjusted to the corresponding surface ups and downs, fully contact the ground, and enhance the grip by inserting the plug posts 8 into the ground, thereby preventing the supporting chassis 2 from slipping when being pushed, enhancing the stability of the device when moving, avoiding the phenomenon of coal gushing due to serious drilling, and thus avoiding the obstruction or breakage of the adhesive tape.

The bottom plate of the trough tunnel is uneven, and the base in the oil cylinder cannot adapt to the undulations of the ground. There is great resistance in the process of pushing the tail of the machine, which may easily lead to serious bottom drilling and coal gushing, causing the belt to be blocked or broken. The base of the oil cylinder may also slide sideways due to the inclination of the ground, and the lack of grip may cause it to lose contact with the ground, resulting in insufficient thrust. In addition, there is a height difference on the ground and local depressions. Multiple lifting cylinders on the same side are generally controlled and operated synchronously. When encountering such terrain, the bottom of some oil cylinders may not be well in contact with the ground and become suspended in the air. The forces on each cylinder are different, which increases the working pressure of the cylinder and may even cause the entire conveyor to become unstable and collapse.
