Description

Technical Field

[0001] This utility model relates to the field of bucket elevators, and in particular to a limit switch device for enhancing the safety of bucket elevator maintenance. Background Technology

[0002] Limestone-gypsum wet desulfurization is a relatively mature flue gas desulfurization technology, widely used in traditional thermal power plants. It employs limestone ground into a slurry using a wet ball mill as a desulfurization diluent. Bucket elevators are commonly used belt conveyors for transporting limestone in traditional thermal power plants, and their maintenance is a crucial part of on-site troubleshooting. However, during maintenance, uneven weight distribution in the buckets can cause the belts to rotate on both sides, increasing the risk of mechanical injury during repairs and potentially leading to personal injury accidents. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a limit device to enhance the safety of bucket elevator maintenance. The belt is clamped by the cooperation of a first limit bar and a second limit bar, wherein the second limit bar provides support for the bucket, which can prevent the belt from swinging and the bucket from rotating with the belt, thereby improving the stability during maintenance and making it safer and more reliable.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a limiter device to enhance the safety of bucket elevator maintenance, including a first limit bar and a second limit bar;

[0005] The first limiting bar is located on the back of the belt at the window, and the two ends of the first limiting bar are respectively located on the windowsill of the window;

[0006] The second limiting bar is located on the front of the belt at the window, and is also located between the upper and lower adjacent hoppers. Both ends of the second limiting bar are fixed to the wall of the lifting cylinder.

[0007] When maintenance is required, the elevator is stopped, and the second limit bar is inserted between the adjacent upper and lower hoppers, with both ends fixed to the elevator cylinder wall. The first limit bar is set on the back of the belt. The first limit bar squeezes the belt to one side of the second limit bar, so that the belt is sandwiched between the first and second limit bars. In particular, the second limit bar will provide support for the hopper, preventing the hopper from driving the belt downward, and also preventing the hopper from driving the belt upward. This can effectively keep the belt and hopper stable and stationary, so that the staff can carry out maintenance safely.

[0008] Preferably, the first limiting bar is a square bar. This makes it more stable when placed on a windowsill and makes it easier to push one side of the second limiting bar with a belt.

[0009] Preferably, the first limiting bar is made of channel steel. This provides high rigidity and greater reliability.

[0010] Preferably, the first limiting bar is a round roller, which facilitates fixing it to the lifting cylinder.

[0011] Preferably, the second limiting bar is made of steel pipe, which can provide sufficient support strength.

[0012] Preferably, the lifting cylinder wall is provided with support holes for the steel pipe to pass through, facilitating the fixing of the second limiting bar to the lifting cylinder.

[0013] Preferably, a clamping assembly is provided on the windowsill corresponding to the first limiting bar downwards. This facilitates locking the position of the first limiting bar so that the belt can be pushed towards the second limiting bar.

[0014] Preferably, the clamping component is a thumb clamp, which makes it easier to lock the position of the first limiting bar.

[0015] The beneficial effects of this utility model are:

[0016] The belt is clamped by the cooperation of the first and second limit bars. The second limit bar provides support for the hopper, which can prevent the belt from swinging and the hopper from rotating with the belt, thus improving its stability during maintenance and making it safer and more reliable.

[0020] To enhance understanding of this utility model, it will be described in further detail below with reference to the accompanying drawings and embodiments. These embodiments are only used to explain this utility model and do not limit the scope of protection of this utility model.

[0021] Example

[0022] like Figure 1 As shown, a limit device for enhancing the safety of bucket elevator maintenance includes a first limit bar 1 and a second limit bar 2.

[0023] The first limiting bar 1 is located on the back of the belt 5 at the window 4, and the two ends of the first limiting bar 1 are respectively located on the windowsill of the window 4;

[0024] The second limiting bar 2 is located on the front of the belt 5 at the window 4, and at the same time, the second limiting bar 2 is located between the upper and lower adjacent hoppers 6, and the two ends of the second limiting bar 2 are fixed to the wall of the lifting cylinder 3.

[0025] When maintenance is required, the elevator is stopped, and the second limit bar 2 is inserted between the adjacent upper and lower hoppers 6, with both ends fixed to the wall of the elevator cylinder 3. The first limit bar 1 is set on the back of the belt 5. The first limit bar 1 squeezes the belt 5 to one side of the second limit bar 2, so that the belt 5 is sandwiched between the first limit bar 1 and the second limit bar 2. In particular, the second limit bar 2 will provide support for the hopper 6, preventing the hopper 6 from driving the belt 5 downward, and also preventing the hopper 6 from driving the belt 5 upward. This can effectively keep the belt 5 and the hopper 6 at a stable stop, so that the staff can safely carry out maintenance.

[0026] The first limiting bar 1 is a square bar. This provides greater stability when placed on a windowsill and makes it easier to push one side of the second limiting bar 2 using the belt 5. The first limiting bar 1 is made of channel steel, offering high rigidity and enhanced reliability.

[0027] The first limiting bar 1 is made of a circular roller. The second limiting bar 2 is made of a steel pipe. Both provide sufficient support strength.

[0028] The lifting cylinder 3 has support holes in its wall for the steel pipe to pass through, facilitating the fixing of the second limiting bar 2 to the lifting cylinder 3.

[0029] The first limiting bar 1 is provided with a clamping component corresponding to the windowsill of the window 4. This facilitates locking the position of the first limiting bar 1 so that the belt 5 can be pushed towards the second limiting bar 2.

[0030] The clamping component is a thumb clamp 8, which makes it easier to lock the position of the first limiting bar 1.

[0031] The beneficial effects of this utility model are:

[0032] The belt 5 is clamped by the cooperation of the first limit bar 1 and the second limit bar 2. The second limit bar 2 provides support for the hopper 6, which can prevent the belt 5 from swinging and the hopper 6 from rotating with the belt 5, thereby improving its stability during maintenance and making it safer and more reliable.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
