Technical Field

[0001] The utility model relates to the field of belt conveyors, in particular to a belt conveyor skidding protection pedal type test device. Background Art

[0002] Belt conveyor is a kind of material conveying equipment widely used in manufacturing enterprises. It is mainly composed of conveyor belt and drive motor as well as supporting equipment, control and protection devices. During the operation of belt conveyor, slippage may occur sometimes. When the belt slips, it will cause the material to flow back and scatter. In severe cases, it may cause abnormal conditions such as increased belt wear, motor burnout and even belt breakage, affecting the safe and stable operation of belt conveyor. Therefore, some slip protection devices are provided in the related technology to send out a slip alarm signal when the drive roller and conveyor belt slip and rub, so that the belt conveyor can automatically stop.

[0003] For example, the patent with application number CN202123277910.9 discloses an anti-slip protection device for a belt conveyor, which mainly comprises a rotation speed sensor with a roller installed above the return belt. When the belt conveyor slips, the conveyor belt stops running and the roller speed drops rapidly to stop. At this time, the rotary speed sensor transmits the roller speed signal to the control box, and the control box automatically controls the conveyor to stop.

[0004] In actual applications, maintenance personnel of belt conveyors need to test whether the slip protection device is working properly every day during maintenance, and fill in test records so that they can promptly detect whether the slip protection device has failed.

[0018] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", "vertical", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] like Figure 1-Figure 3 A belt conveyor slip protection pedal test device shown in the figure includes a belt conveyor and a roller speed sensor 4. The belt conveyor includes a frame 1, a roller 2 and a belt 3. The roller 2 is rotatably arranged on the frame 1, and the belt 3 is arranged on the roller 2. The belt 3 is divided into an upper and lower layer. The roller speed sensor 4 is arranged on the upper surface of the lower belt 3. The roller speed sensor 4 is connected to the main controller of the belt conveyor. When the belt 3 operates normally, the belt 3 will drive the roller speed sensor 4 to rotate normally. When the belt 3 slips, the roller speed sensor 4 will stop rotating. At this time, the main controller can control the belt conveyor to automatically stop. This is the main structure of the existing slip protection device. For specific contents, please refer to the patent description with application number CN202123277910.9.

[0022] The belt conveyor in this solution still uses the skidding protection device of the roller speed sensor 4, but an additional set of pedal-type test device is provided so that maintenance personnel can check whether the skidding protection device is working properly during routine maintenance.

[0023] Specifically, if Figure 2 and Figure 3 As shown, the pedal test device includes a pedal member 5, a transmission mechanism and a brake member. A wheel frame 11 that can rotate up and down is provided on the frame 1, a roller speed sensor 4 is rotatably provided on the wheel frame 11, the brake member is located above the roller speed sensor 4 and connected to the frame 1, and the pedal member 5 is located beside the frame 1 and connected to the wheel frame 11 through the transmission mechanism.

[0024] During maintenance, the staff can step on the pedal 5 to move it downward. At this time, under the action of the transmission mechanism, the wheel frame 11 will be swung upward, thereby driving the roller speed sensor 4 to contact the brake member upward. The roller speed sensor 4 is braked and stops rotating. If the belt conveyor stops automatically at this time, it means that the slip protection device is working normally. If the belt conveyor does not stop, it means that the slip protection device has a fault and needs maintenance.

[0025] In specific settings, such as Figure 3 As shown, the brake component includes a brake pad 10 and a bracket 9 , the brake pad 10 is arranged on the bracket 9 , and the bracket 9 is connected to the frame 1 .

[0026] The transmission mechanism includes a soft rope 6 and a fixed pulley 8. The fixed pulley 8 is rotatably arranged on the frame 1. One end of the soft rope 6 is connected to the pedal 5, and the other end is passed around the fixed pulley 8 upwards and then connected to the wheel frame 11 downwards. Therefore, when the pedal 5 is stepped on downwards, the pedal 5 pulls the soft rope 6 downwards, and the soft rope 6 pulls the wheel frame 11 upwards to swing. After the pedal 5 is released, the wheel frame 11 automatically swings downwards and resets under the action of its own weight. This driving form is simple, easy to use, and easy to manufacture and implement.

[0027] Furthermore, a channel steel frame 7 is provided on the frame 1, and a fixed pulley 8 is rotatably provided on the channel steel frame 7. There are two fixed pulleys 8, one is provided above the pedal 5, and the other is provided above the wheel frame 11. A rope threading hole is provided on the channel steel frame 7, and the rope threading hole is located above the wheel frame 11 for the soft rope 6 to pass downward and connect with the wheel frame 11. The channel steel frame 7 has a groove, so it is convenient to place the fixed pulley 8, and the overall structure is relatively compact.

[0028] In summary, this solution mainly adds a set of pedal-type test device to the existing skidding protection device, so that maintenance personnel can check whether the skidding protection device is working properly during daily maintenance. The overall structure of this device is simple, easy to operate and highly practical.

[0029] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
