Description
Technical Field
[0001] The utility model relates to a device for preventing a hopper from deviating, in particular to the structure of the device for preventing a hopper from deviating. Background Art
[0002] In the production of cement, raw materials such as limestone, clay, iron powder and coal are needed. The products produced include semi-finished silicate cement clinker and finished cement. These materials need to be transported by chain bucket conveyor. Figure 5 As shown, the chain bucket conveyor 6 is a device that uses a bucket running along a track to transport materials horizontally or obliquely. It consists of a conveying platform 62, a track 63, a bucket 61, a driving mechanism 64 and a chain 65. The track 63 is set on the conveying platform 62. The driving mechanism 64 pulls the bucket 61 filled with materials along the track 63 through the chain 65 for horizontal or oblique transportation. The chain bucket conveyor is suitable for the transportation of some solid materials with high temperature, large capacity, large size, sharp edges and strong abrasiveness.
[0003] When the chain bucket conveyor is running, due to the large material transportation volume, the bucket is affected by various factors such as the inclination of the material center of gravity and the track, resulting in the bucket often jumping the track, running off the track, etc., and the bucket jumping the track and running off the track will cause equipment damage and shutdown, making it impossible to transport materials normally. Maintenance requires a lot of time and seriously affects normal production.
[0004] If the hopper jumps or deviates, it may damage the surrounding equipment and injure nearby workers, posing a certain safety hazard. It may also cause the material in the hopper to spill and pollute the environment in the workshop.
[0005] The existing method usually sets a guardrail on the outside of the chain bucket conveyor to prevent workers from being injured, but this method cannot solve the problem of the bucket jumping and running off the track.
[0006] The utility model aims to provide a device for preventing a bucket from deviating, so as to solve the problem that the bucket of a chain bucket conveyor is easy to jump off the track and deviate. Utility Model Content
[0007] In order to solve the above problems, the utility model provides a device for preventing the hopper from running off track, including a support plate 1, a clamping member 2, a buffer member 3 and a rolling member 4. The support plate 1 is arranged vertically, and the clamping member 2 is fixedly arranged at the bottom of the support plate 1 for fixing on the conveying platform. The buffer member 3 includes a buffer rod 31, a buffer cylinder 32 and a buffer spring 33. The rear end of the buffer rod 31 is fixedly connected to the support plate 1, and the front end extends horizontally forward. The rear end of the buffer cylinder 32 is sleeved on the buffer rod 31 and is slidably connected to the buffer rod 31. A snap ring 322 is arranged on the buffer cylinder 32. The buffer spring 33 is sleeved on the buffer rod 31, and its two ends are respectively in contact with the snap rings 322 on the support plate 1 and the buffer cylinder 32. The rolling member 4 includes a roller 41, and the roller 41 is rotatably arranged on the front end of the buffer cylinder 32.
[0008] When the utility model is used, according to the length of the chain bucket conveyor, a suitable number of anti-bucket deviation devices are selected, and multiple devices are fixed on both sides of the conveying platform of the chain bucket conveyor at equal intervals through the clamping member 2, so that the roller 41 faces the bucket of the chain bucket conveyor and contacts the outer side of the bucket. When the bucket is tilted, the bucket squeezes the roller 41 outward, and the roller 41 rotates with the movement of the bucket, and squeezes the buffer spring 33 through the buffer cylinder 32. After the buffer spring 33 is contracted by force, a reverse force is applied to the buffer cylinder 32, which is applied to the bucket through the roller 41, so that the bucket returns to normal.

The roller 41 is rotatably set at the front end of the buffer cylinder 32. When the hopper is tilted, the hopper squeezes the roller 41 outward. The roller 41 rotates with the movement of the hopper and squeezes the buffer spring 33 through the buffer cylinder 32. After the buffer spring 33 is contracted by force, a reverse force is applied to the buffer cylinder 32 through the roller 41 to restore the hopper to normal. This prevents the hopper from jumping the track and running off the track, causing accidents and dangers, and affecting normal production.

DETAILED DESCRIPTION
[0024] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.
[0025] like Figure 1 and Figure 2 As shown, the device for preventing the hopper from deviation comprises a support plate 1, a clamping member 2, a buffer member 3 and a rolling member 4.
[0026] The support plate 1 is a rectangular flat plate, which is arranged vertically. Two clamping members 2 are arranged at the bottom of the support plate 1, and the clamping members 2 are used to fix the support plate 1 on the conveying platform.
[0027] The clamping member 2 is U-shaped, with its opening facing the front. The clamping member 2 includes a connecting plate 21 and an upper clamping plate 22 and a lower clamping plate 23 respectively arranged on the upper and lower sides of the connecting plate 21. The connecting plate 21 is fixedly connected to the support plate 1 through a connecting rod 25, and a plurality of clamping bolts 24 are arranged on the lower clamping plate 23.
[0028] When installing the clamping member 2, clamp the opening of the clamping member 2 on one side of the conveying platform, and turn the clamping bolt 24 so that the clamping bolt 24 abuts and fixes on the conveying platform, thereby fixing the clamping member 2 to the conveying platform.
[0029] like Figure 1 and Figure 3 As shown, two buffer members 3 are arranged on the support plate 1, and the two buffer members 3 are arranged side by side in the vertical direction to maintain a spacing. The two buffer members 3 can balance the force on the roller 41 and increase the buffering force.
[0030] The buffer member 3 includes a buffer tube 32, a buffer rod 31 and a buffer spring 33. A limit ring 321 is provided on the inner wall of the rear end of the buffer tube 32, and a clamping ring 322 is provided on the outer wall of the rear end of the buffer tube 32.

[0032] The sliding part 311 matches with the buffer tube 32 , wherein the matching means that the diameter of the sliding part 311 is equal to or slightly smaller than the inner diameter of the buffer tube 32 , so that the sliding part 311 can be inserted into the buffer tube 32 and slide in the buffer tube 32 , and the outer wall of the sliding part 311 fits with the inner wall of the buffer tube 32 .
[0033] The connecting portion 312 matches the limiting ring 321 , the front end is fixedly connected to the sliding portion 311 , and the rear end passes through the limiting ring 321 and is fixedly connected to the supporting plate 1 through the adjusting member 5 .
[0034] The connecting portion 312 matches with the limiting ring 321, wherein the matching means that the diameter of the connecting portion 312 is equal to or slightly smaller than the inner diameter of the limiting ring 321, so that the connecting portion 312 can be inserted into the limiting ring 321 and slide relative to the limiting ring 321, and the outer wall of the connecting portion 312 fits with the inner wall of the limiting ring 321.
[0035] The buffer rod 31 includes a sliding portion 311 and a connecting portion 312 which are connected to each other. The sliding portion 311 is slidably arranged in the buffer tube 32. A limiting ring 321 is arranged on the inner side wall of the rear end of the buffer tube 32. The limiting ring 321 can prevent the buffer tube 32 from being separated from the buffer rod 31.
[0036] The buffer spring 33 is sleeved on the buffer rod 31 , and two ends thereof are respectively in contact with the support plate 1 and the clamping ring 322 on the buffer tube 32 .
[0037] The adjusting member 5 includes an adjusting screw 51 and an adjusting nut 52. An adjusting hole matching the adjusting screw 51 is provided on the support plate 1. The front end of the adjusting screw 51 is fixedly connected to the rear end of the buffer rod 31, and the rear end extends through the adjusting hole to the rear side of the support plate 1.
[0038] The adjusting nut 52 is sleeved on the rear end of the adjusting screw rod 51 to fix the adjusting screw rod 51 to the supporting plate 1 .
[0039] The rear end of the buffer rod 31 is fixedly connected to the support plate 1 through an adjusting member 5. An adjusting hole is provided on the support plate 1. The adjusting screw 51 is inserted into the adjusting hole and fixed by an adjusting nut 52. Thus, the forward extension length of the buffer rod 31 can be adjusted according to actual conditions, and the buffering distance and strength of the buffer spring 33 can be adjusted.
[0040] like Figure 1 and Figure 4 As shown, the rolling element 4 further includes a roller 41 , a roller shaft 42 , a bearing 43 and a sealing gland 44 .
[0041] The roller 42 is vertically arranged, and both ends of the roller 42 are fixedly connected to the front ends of the buffer cylinders 32 of the two buffer members 3 , respectively. The roller 41 is arranged on the roller 42 via a bearing 43 .
[0042] Two sealing glands 44 are respectively fixedly disposed on both sides of the roller 41 . The sealing glands 44 rotate with the roller 41 relative to the roller shaft 42 to prevent the bearing 43 and the roller 41 from axially moving.
[0043] The two ends of the roller 42 are respectively fixedly connected to the front ends of the buffer cylinders 32 of the two buffer members 3, and the roller 41 is arranged on the roller 42 through the bearing 43, which can improve the rotation efficiency of the roller 41, reduce friction, prevent affecting the movement of the hopper, and extend the service life of the equipment.
[0044] The roller 41 is rotatably arranged at the front end of the buffer cylinder 32. When the hopper is tilted, the hopper squeezes the roller 41 outward. The roller 41 rotates with the movement of the hopper and squeezes the buffer spring 33 through the buffer cylinder 32. After the buffer spring 33 is contracted by the force, a reverse force is applied to the buffer cylinder 32, which is applied to the hopper through the roller 41 to restore the hopper to normal.
[0045] like Figure 5 As shown, when the utility model is used, according to the length of the chain bucket conveyor 6, a suitable number of anti-bucket deviation devices are selected, and multiple devices are fixed in sequence and at equal intervals on both sides of the conveying platform 62 of the chain bucket conveyor 6 through the clamping member 2, so that the roller 41 faces the bucket 61 of the chain bucket conveyor 6 and contacts the outer side surface of the bucket 61. When the bucket 61 is tilted, the bucket 61 squeezes the roller 41 outward, and the roller 41 rotates with the movement of the bucket 61, and squeezes the buffer spring 33 through the buffer cylinder 32. After the buffer spring 33 is contracted by the force, a reverse force is applied to the buffer cylinder 32, which is applied to the bucket 61 through the roller 41, so that the bucket 61 returns to normal.
[0046] The utility model can fix the support plate 1 to one side of the conveying platform by setting the clamping member 2, setting the buffer member 3, fixing the rear end of the buffer rod 31 to the support plate 1, and the rear end of the buffer cylinder 32 is sleeved on the buffer rod 31 and slidably connected with the buffer rod 31. The buffer spring 33 is sleeved on the buffer rod 31, and the two ends are respectively in contact with the clamping ring 322 on the support plate 1 and the buffer cylinder 32. The roller 41 is rotatably set at the front end of the buffer cylinder 32. When the hopper is tilted, the hopper squeezes the roller 41 outward. The roller 41 rotates with the movement of the hopper and squeezes the buffer spring 33 through the buffer cylinder 32. After the buffer spring 33 is contracted by force, a reverse force is applied to the buffer cylinder 32 through the roller 41 to restore the hopper to normal. This prevents the hopper from jumping the track and running off the track, causing accidents and dangers, and affecting normal production.
[0047] The rolling element 4 also includes a roller 42, a bearing 43 and a sealing cover 44. The two ends of the roller 42 are fixedly connected to the front ends of the buffer cylinders 32 of the two buffer elements 3 respectively. The roller 41 is arranged on the roller 42 through the bearing 43, which can improve the rotation efficiency of the roller 41, reduce friction, prevent affecting the movement of the hopper, and extend the service life of the equipment.
[0048] The rear end of the buffer rod 31 is fixedly connected to the support plate 1 through the adjusting member 5, and an adjusting hole is provided on the support plate 1. The adjusting screw 51 is inserted into the adjusting hole and fixed by the adjusting nut 52, so that the length of the buffer rod 31 extending forward can be adjusted according to actual conditions, and the buffering distance and strength of the buffer spring 33 can be adjusted. The buffer rod 31 includes a sliding portion 311 and a connecting portion 312 connected to each other, and the sliding portion 311 is slidably arranged in the buffer cylinder 32. A limiting ring 321 is provided on the inner side wall of the rear end of the buffer cylinder 32, and the limiting ring 321 can prevent the buffer cylinder 32 from being separated from the buffer rod 31.
[0049] It should be noted that the above-mentioned embodiments illustrate rather than limit the invention and that those skilled in the art will be able to design alternative embodiments without departing from the scope of the appended claims.
