Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of belt conveyor, concretely relates to a kind of unpowered automatic deviation rectifying device and belt conveyor. BACKGROUND

[0002] In many fields such as industrial production and logistics transportation, belt conveyor is widely used as an important material conveying equipment. However, due to the manufacturing deviation of the conveying belt, the precision problem in the installation process, the uneven distribution of materials on the conveying belt, the wear of the conveyor roller and the drum, and the vibration in the running process, the belt conveyor is prone to belt deviation problem in the running process.

[0003] In order to solve the problem of belt deviation, the deviation rectifying devices of belt conveyor on the market at present are mainly divided into the following four types:

[0004] 1. Mechanical transmission type deviation rectifying device, its working principle is that when the conveying belt deviates from the theoretical center line of the conveyor, the axis of the roller in the deviation rectifying device will deflect a certain angle around the rotation center in the corresponding direction, and then generate a transverse friction force perpendicular to the running direction of the conveying belt between the roller and the conveying belt, so as to make the conveying belt return to the correct position. However, this device has many defects, such as simple structure, unable to automatically adjust the deviation rectifying force, poor working stability, prone to left and right swing, large running resistance of the conveying belt, and easy to aggravate the wear of the conveying belt.

[0005] 2. Hydraulic automatic deviation rectifying device, its working principle is that by acting on the upper and lower self-aligning rollers, the deviation rectifying roller angle is actively adjusted when the conveying belt deviates, so as to achieve the purpose of correcting deviation. However, this device has large initial investment and high cost, and its volume is large, occupying more space. In addition, it will also rub with the edge of the conveying belt in the running process, which is easy to cause damage to the conveying belt. Moreover, due to the complexity of its hydraulic transmission link, it also has the problem of high failure rate of parts;

[0006] 3. Pneumatic automatic deviation rectifying device, its working principle is that first, deviation signal is received by means of deviation sensor, and then after processing by main controller, electromagnetic valve is driven to open, so as to push the fine adjustment cylinder to act, so as to generate deviation rectifying force to correct the deviation of the conveying belt. However, this device also has the problems of large initial investment, complex installation and debugging process, and difficult operation and maintenance.

[0007] 4. The working principle of the electro-hydraulic combined deviation correcting device is that when the conveying belt deviates, the deviation is recognized by the direction sensor and the signal is transmitted to the electric control box, the electric control box recognizes the signal and makes the electro-hydraulic push rod electrified, the piston rod of the electro-hydraulic push rod extends, drives the training roller to deflect in the set direction, and drives the conveying belt to correct by using the friction force. However, in special working conditions, the accuracy of the sensor may be affected due to the harsh environment, so the device has high requirements for the environment, which limits its application in some complex environments.

[0008] In summary, the existing deviation correcting devices for belt conveyors have different degrees of shortcomings in actual application, and it is difficult to meet the needs of efficient, stable and low maintenance cost operation of belt conveyors in industrial production. Therefore, there is an urgent need for a new deviation correcting device to overcome the shortcomings of the existing technology. Content of the utility model

Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0023] Example 1

[0024] like Figure 1 As shown in the figure, this embodiment provides a non-powered automatic correction device, which includes a frame 1. The frame 1 includes two pairs of columns arranged in parallel, and a supporting beam is connected between the upper ends of each pair of columns. A connecting beam is connected between the lower ends of one pair of columns.

[0025] Specifically, in this embodiment, a first supporting beam 4 and a second supporting beam are arranged parallel to each other along the length of the two supporting beams. Furthermore, a sliding ring 6 is welded to the upper part of both the first supporting beam 4 and the second supporting beam. A left connecting rod 3 is horizontally slidably installed at the first supporting beam 4 along its own width direction via the sliding ring 6 on the upper part of the first supporting beam 4, and a right connecting rod is horizontally slidably installed at the second supporting beam 2 along its own width direction via the sliding ring 6 on the upper part of the second supporting beam.

[0026] The left connecting rod 3 has a rod diameter smaller than the inner hole size of the sliding ring 6 at the supporting longitudinal beam one 4, and the left end of the left connecting rod 3 is fixedly arranged with the left deviation adjusting shaft one by welding or the like, and the outer side of the left deviation adjusting shaft one is rotatably arranged with the left deviation adjusting vertical roller one 5 through a bearing or the like. The right end of the left connecting rod 3 is rotatably arranged with the right pushing plate 2 through a bearing or the like, the upper part of the right pushing plate 2 is arranged with a rotating shaft 8, the rotating shaft 8 is rotatably connected with the supporting cross beam in the rack 1 through a bearing or the like, and the left connecting rod 3 can rotate a certain angle horizontally in the sliding ring 6 through the gap between the left connecting rod 3 and the sliding ring 6 at the supporting longitudinal beam one 4, and through the right pushing plate 2 made of rubber material, so as to ensure that the left connecting rod 3 can smoothly slide, and the right pushing plate 2 can smoothly rotate.

[0027] The rod diameter of the right connecting rod is smaller than the inner hole size of the sliding ring 6 at the supporting longitudinal beam two, and the right end of the right connecting rod is fixedly arranged with the right deviation adjusting shaft one by welding or the like, and the outer side of the right deviation adjusting shaft one is rotatably arranged with the right deviation adjusting vertical roller one.

At this time, if the belt of the belt conveyor is in a deviation state, the corresponding deviation adjusting vertical roller two 7 can be used to preliminarily adjust the belt in a first level. If the belt of the belt conveyor continues to deviate, the belt will contact the corresponding deviation adjusting vertical roller one, and push the deviation adjusting vertical roller one to move in the deviation direction, so as to drive the corresponding pushing plate to rotate, and the pushing plate can be used to push the material above the belt in the opposite direction, so as to adjust the stress state of the belt surface, and finally realize automatic deviation correction under the action of the material gravity.
