The embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

With reference to fig. 1 to 5, an embodiment of the present application discloses a supporting device for a conveyor belt, which can be used for a conveyor. The disclosed supporting device for a conveyor belt includes a rotation member 100, a bracket 200, a base 300, and a locking mechanism.

Wherein the base 300 is provided on a support surface of a support device for a conveyor belt, such as the ground or a frame of a conveyor. Alternatively, the base 300 may be connected to the supporting surface by means of bolts 900 or welding. The first end 210 of the stand 200 is rotatably coupled to the base 300. In an alternative embodiment, the base 300 is provided with a mounting protrusion 310, and the first end 210 of the bracket 200 can be rotatably provided on the mounting protrusion 310 through a first rotating shaft 810. A locking mechanism is provided between the stand 200 and the base 300 for locking the relative positions of the stand 200 and the base 300. Optionally, the base 300 and the bracket 200 may be made of metal.

In the case where the rotation member 100 is provided to the holder 200, the locking mechanism is locked, and the holder 200 and the base 300 are relatively fixed. At this time, an included angle is formed between the bracket 200 and the base 300, the included angle between the bracket 200 and the base 300 may be 90 degrees, and of course, the included angle between the bracket 200 and the base 300 may be adjusted according to specific situations. Alternatively, the rotating member 100 may be a top pulley, a dragging roller, a roller, or the like, in the case that the rotating member 100 is a top pulley, the bracket 200 may be rotatably connected to the base 300 through the second rotating shaft 820 and a bearing, and the number of the top pulleys may be plural. Alternatively, the rotating member 100 may be made of metal, rubber, or other materials. Under the condition, the conveyer belt 1000 can be wound on the rotating piece 100, and the rotating piece 100 can drive the conveyer belt 1000 to move to realize material transportation.

With the rotatable member 100 disengaged from the bracket 200, the locking mechanism is unlocked and the bracket 200 can be rotated about the first end 210 relative to the base 300 to allow the bracket 200 to tilt. In this case, the rack 200 can rotate relative to the base 300, so that the rack 200 is tilted, and the tilted rack 200 and the conveyor belt 1000 are separated from each other, thereby preventing the conveyor belt from being torn.

In the embodiment of the present application, in the case that the rotating member 100 is normally disposed on the bracket 200, that is, the rotating member 100 can normally operate, the locking mechanism is locked, and the bracket 200 can be fixed to the base 300, so that the bracket 200 can support the rotating member 100; when the rotating member 100 falls off from the holder 200 due to wear caused by long-term operation, the locking mechanism is unlocked, and the holder 200 can rotate relative to the base 300, so that the holder 200 tilts, the conveyor belt and the holder 200 are separated from each other, and the conveyor belt 1000 is prevented from being worn or torn. Therefore, the present application can solve the problem in the related art that the rotating member 100 falls off from the supporting device during the operation of the conveyor, and the moving conveyor belt directly contacts the supporting device, which causes the wear or tear of the support belt.

The locking mechanism may be various as long as the relative positions of the locking bracket 200 and the base 300 can be achieved. In an alternative embodiment, the locking mechanism may include a first clip 220 and a second clip 400, the first clip 220 may be disposed on the bracket 200, the second clip 400 may be disposed on the base 300, and the locking mechanism is locked when the first clip 220 and the second clip 400 are clipped; in the case where the first and second clips 220 and 400 release the clipping, the locking mechanism is unlocked. It should be noted that the first engaging member 220 and the bracket 200 may be a split structure, or may be an integrated structure, that is, the first engaging member 220 may form a part of the bracket 200. In this case, the first clip 220 and the second clip 400 lock and unlock the base 300 and the bracket 200, and the structure is simple and reliable.

In order to realize that the supporting frame 200 is rotatably disposed on the base 300, the supporting device for a conveyor belt may further include a detecting element for detecting a state of the rotating member 100, a driving mechanism connected to the supporting frame 200 for driving the supporting frame 200 to rotate, and a controller for controlling the driving mechanism to be turned on so that the driving mechanism drives the supporting frame 200 to rotate and the supporting frame 200 and the conveyor belt 1000 are separated from each other, in a case where the rotating member 100 is separated from the supporting frame 200, the detecting element detects this information and transmits the information to the controller. However, in the above embodiment, in the case where any one of the driving mechanism, the controller, or the detecting element is out of order, the driving mechanism cannot smoothly drive the support frame 200 to rotate, and the conveying belt 1000 may still be torn.

In order to solve the above problem, one side of the first end 210 of the bracket 200 may be provided with an arc-shaped structure 230, the first clamping member 220 may be provided at the other side of the first end 210, and a direction from the first clamping member 220 to the arc-shaped structure 230 may be consistent with an operation direction of the conveyor belt 1000. After the rotating member 100 is separated from the bracket 200, due to the action of gravity, the conveying belt 1000 drops on the bracket 200 and is in direct contact with the bracket 200, and under the action of inertia, the conveying belt 1000 can continuously move for a distance along the original path, in the process, the conveying belt 1000 applies friction force to the bracket 200 along the running direction of the conveying belt, and the bracket 200 topples over under the action of the friction force, so that the bracket 200 and the conveying belt 1000 are separated from each other, and the conveying belt 1000 is prevented from being torn. In this case, the support 200 is directly driven to tilt by the friction force between the conveyor belt 1000 and the support 200, and the support 200 does not need to be driven to tilt by other driving mechanisms.

In the above solution, in order to release the clamping between the first clamping member 220 and the second clamping member 400, the supporting device for the conveying belt may further include an actuating link 500, the actuating link 500 includes a third end 510 and a fourth end 520, the third end 510 protrudes from the bracket 200 in a direction away from the base 300, and when the rotating member 100 is disposed on the bracket 200, a distance from an upper end surface of the rotating member 100 to the base 300 is greater than a distance from an upper end surface of the third end 510 to the base 300, so as to prevent the third end 510 from directly contacting the conveying belt 1000, which may cause wear of the conveying belt 1000. The action link 500 is movable relative to the stand 200 in a direction toward the base 300 and a direction away from the base 300. The second clip 400 includes a first connecting portion 410 and a second connecting portion 420, wherein the first connecting portion 410 is rotatably connected to the base 300, and the second connecting portion 420 is rotatably connected to the fourth end 520. Alternatively, the actuating link 500 may be made of metal.

Referring to fig. 2 again, when the rotating member 100 is separated from the bracket 200, the conveyer belt 1000 moves toward the base 300 under the action of gravity, and in the process of moving the conveyer belt 1000, the conveyer belt 1000 contacts with the third end 510 of the action link 500 and applies an acting force to the action link 500 toward the base 300 to drive the action link 500 to move toward the base 300, and the action link 500 drives the second engaging member 400 to rotate around the first connecting portion 410 through the second connecting portion 420, so that the first engaging member 220 and the second engaging member 400 are disengaged from each other. Under this condition, the process that the conveyer belt dropped and the process of first joint spare 220 and second joint spare 400 contact joint go on simultaneously, and at the in-process that the conveyer belt dropped, support 200 switches gradually to can be for base 300 pivoted state, avoids the conveyer belt to have dropped to support 200 on, but support 200 still is in the fixed state of relative base 300, leads to the conveyer belt to tear. The arrows in fig. 2 indicate the moving direction of each member.

In order to improve the moving accuracy of the action link 500, the bracket 200 may be provided with a boss 240, the boss 240 may be provided with a guide 250, the third end 510 of the action link 500 may be provided with a guide groove 511, and the guide 250 and the guide groove 511 may be guided to be engaged in the moving direction of the action link 500. Optionally, the guide 250 may be a pin shaft disposed on the protrusion 240, and the guide slot 511 may be a U-shaped slot, and the pin shaft extends into the U-shaped slot to perform a guiding function. In this case, the actuating link 500 moves under the guiding action of the guide 250 and the guide slot 511, so as to prevent the movement path of the actuating link 500 from deviating, and further prevent the first engaging member 220 and the second engaging member 400 from being unable to smoothly release the engagement.

The notch of the guide groove 511 may be flush with the end surface of the third end 510 to facilitate the assembly and disassembly of the action link 500.

In a further technical solution, the supporting device for a conveyor belt may further include an elastic member 600, one end of the elastic member 600 may be connected to the second clamping member 400, and the other end of the elastic member 600 may be supported on a supporting surface of the supporting device for a conveyor belt. In the case that the rotation member 100 is disposed on the bracket 200, the elastic member 600 is used to prevent the second engaging member 400 from rotating, and in this case, the elastic member 600 may apply a supporting force to the second engaging member 400, the direction of the supporting force being opposite to the direction of the acting force applied to the second engaging member 400 when the action link 500 moves toward the base 300. When the actuating link 500 moves in a direction toward the base 300, the elastic member 600 is elastically deformed. Alternatively, the elastic member 600 may be a coil spring or an elastic column. Under this kind of circumstances, set up elastic component 600 and can prevent that second joint spare 400 from taking place to rotate because of reasons such as maloperation, leading to first joint spare 220 and second joint spare 400 to relieve the joint.

In order to further protect the conveyor belt 1000, the supporting device for a conveyor belt may further include a power-off protection switch 700, the power-off protection switch 700 is electrically connected to the power unit of the conveyor, and in case that the rotating member 100 is detached from the bracket 200, the power-off protection switch 700 is turned on and the power unit is turned off. Optionally, the power-off protection switch 700 may be a travel switch, and of course, other kinds of switches may be used for the power-off protection switch 700, which is not limited herein. In this case, when the rotating member 100 is separated from the bracket 200, the power-off protection switch 700 controls the conveyor to stop, so that the conveyor belt 1000 stops moving, thereby protecting the conveyor belt 1000 and preventing the conveyor belt from being torn.

In a further embodiment, the power down protection switch 700 may be disposed on the bracket 200, the power down protection switch 700 may have a contact 710, the actuating link 500 may be disposed with a contact rod 530, and in case that the actuating link 500 moves toward the base 300, the contact rod 530 contacts the contact 710 to trigger the power down protection switch 700. Under the condition, in the process that the action connecting rod 500 moves towards the direction of the base 300, the first clamping piece 220 and the second clamping piece 400 can be clamped and the power-off protection switch 700 can be triggered, so that the purpose of dual purposes of one object is achieved.

As described above, the first clip member 220 and the second clip member 400 are clipped, and optionally, the first clip member 220 may have the first surface 221, the second clip member 400 may have the second surface 421, and the second surface 421 may be one surface of the second connecting portion 420. When the second surface 421 is mounted on the first surface 221, the first clip 220 is clipped to the second clip 400; when the second surface 421 is separated from the first surface 221, the first clip member 220 is released from the second clip member 400. Under this kind of condition, when first joint spare 220 and second joint spare 400 joint, the area of contact of the two is great for the lifting surface area of first joint spare 220 is great, and then promotes the joint stability of first joint spare 220 and second joint spare 400, that is to say, improves the joint stability of support 200 and second joint spare 400, and then promotes the joint strength of base 300 and support 200.
