Description

A device for preventing chain conveyor plate tipping Technical Field

[0001] This utility model patent belongs to the field of chain conveyor technology, specifically relating to a device for preventing the chain plates of a chain conveyor from tipping over. Background Technology

[0002] A single-chain submerged scraper conveyor is a transport device that uses a scraper chain moving within a closed casing to transport bulk materials to a predetermined destination. It has advantages such as small size, strong sealing, good rigidity, flexible process layout, convenient installation and maintenance, and the ability to feed and unload at multiple points. Therefore, it significantly improves workers' working conditions and prevents environmental pollution. The heavy calcium carbonate workshop uses two sets of L=27m single-chain submerged scraper conveyors to transport dust collected by the bag filter of the granulation unit (as shown in Figures 1 and 2).

[0003] In actual production, the inventors discovered that both devices had the following two problems:

[0004] 1. During operation, the 170mm wide upper chain plate of the scraper conveyor needs to repeatedly slide suspended for 27 meters on a track only 30mm wide. The scraper blades lack support, causing the chain plate to sway left and right on the track due to its up-and-down flapping motion. This exacerbates wear on the track surface and roller sleeves, gradually transforming the contact surface from a flat plane to a curved surface. The chain plate's balance is weakened, further increasing swaying and friction, creating a vicious cycle. Furthermore, material accumulation on the track is another adverse factor. Therefore, both machines require approximately 6 hours of downtime every 7-10 days for maintenance, requiring 4 maintenance personnel to grind and level the track and replace worn roller sleeves. This significantly disrupts production.

[0005] 2. If the chain plate is not adjusted in time or is adjusted improperly, the equipment will operate with defects, which will cause the upper chain plate of the conveyor to derail and overturn. This will result in the chain plate assembly scraping and damaging the track, the machine casing, or even overloading and damaging other transmission components or burning out the motor, causing equipment accidents. This will not only damage a large number of parts, but also affect the production start-up rate.

[0006] To address the aforementioned problems, this utility model proposes a device for preventing the chain plates of a chain conveyor from tipping over. Summary of the Invention

[0007] To address the aforementioned problems, this utility model proposes a device to prevent the chain conveyor chain plates from tipping over. This device can prevent the chain conveyor chain plates from tipping over and can also detect the swaying of the chain conveyor chain plates at any time for timely adjustments to avoid affecting production efficiency.

[0008] To achieve the above-mentioned technical effects, this utility model is implemented through the following technical solution: a device for preventing chain plate tipping of a chain conveyor, comprising a material inlet pipe, fastening bolt A, a cover, a single chain scraper assembly, a chain plate pin, a scraper, an outer chain plate, an inner chain plate, a roller sleeve, a track, a track tie rod, a housing, a stabilizing bracket, and a level detection device. The cover is installed on the housing via fastening bolt A, and the material inlet pipe is installed on the cover. The single chain scraper assembly is assembled from the chain plate pin, the scraper, the outer chain plate, the inner chain plate, and the roller sleeve, and is slidably installed on the track via the roller sleeve. The track is installed on the housing via the track tie rod. Several sawn sections are provided on the track between the track tie rods. The stabilizing bracket is installed on the housing on both sides of the track sections and is fixedly supported by the track at both ends of the sections. The level detection device can be installed on the housing outside the head wheel or tail wheel of the conveyor, and the detection direction of the level detection device is always facing the positioning cursor in the stabilizing bracket.

[0009] Preferably, the stabilizing bracket further includes an L-shaped track rod, a mounting plate, a fastening bolt hole structure, a fixing groove, a roller, a 7-type positioning frame, and a cursor. The L-shaped track rod and the roller are both mounted on the machine housing through the mounting plates at both ends and the fastening bolt hole structure. The L-shaped track rod is divided into two groups and installed on the left and right sides of the roller. The fixing groove in the middle of the L-shaped track rod supports and fixes the track at both ends of the break. A 7-type positioning frame is installed on the upper side of the mounting plate, and a cursor is glued to the crossbar on the upper side of the 7-type positioning frame.

[0010] Preferably, the upper surface of the idler roller is 2-5 mm higher than the upper surface of the track.

[0011] Preferably, the cursor adopts a square film structure, and a circular target-shaped reflective patch is provided at the lower right corner of the square film near the upper outer side of the outer chain plate.

[0012] Preferably, the horizontal detection device can be a laser rangefinder.

[0013] The beneficial effects of this utility model are:

[0014] This device allows for the installation of stabilizing supports at several sections of the track as needed. The idlers within these supports provide support to the chain plates, and they can rotate freely with the chain plates, thus breaking the vicious cycle of increasing swaying friction and reducing sliding friction between the chain plates and the track. This improves the reliability of the equipment. Furthermore, a leveling detection device installed on the outer casing of the conveyor's head or tail wheel can detect whether the outer chain plates are shaking or at risk of tipping by aligning with a circular reflective patch. This allows for convenient periodic inspections by personnel without opening the casing. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Embodiment 1

[0024] As shown in Figures 1 to 5, the existing technology in this embodiment has the following problems: In actual production, the inventors found that both single-chain buried scraper conveyors have the following two problems: 1. During operation, the chain plate needs to repeatedly slide suspended on the track. The scraper blades of the chain plate lack support, which causes the chain plate to sway left and right on the track, thereby aggravating the wear of the track surface and roller sleeves and forming a vicious cycle. It is necessary to replace the worn roller sleeves and perform maintenance and adjustment multiple times. This causes great interference to production; 2. If the chain plate is not adjusted in time or is adjusted improperly, the equipment will operate with defects, causing the upper chain plate of the conveyor to derail and overturn. This will cause the chain plate assembly to scrape and damage the track, the casing, or even overload and damage other transmission components or burn out the motor, resulting in equipment accidents. This not only damages a large number of parts, but also affects the production start-up rate.

[0025] Therefore, the inventor provides a device to prevent the chain plate of a chain conveyor from tipping over, including a material inlet pipe 1, fastening bolts A2, a cover 3, a single chain scraper assembly 4, a chain plate pin 5, a scraper 6, an outer chain plate 7, an inner chain plate 8, a roller sleeve 9, a track 10, a track tie rod 11, a housing 12, a stabilizing bracket, and a level detection device 20. The cover 3 is installed on the housing 12 by fastening bolts A2, and the material inlet pipe 1 is installed on the cover 3. The single chain scraper assembly 4 consists of the chain plate pin 5, the scraper 6, the outer chain plate 7, the inner chain plate 8, and the roller sleeve. The cylinder 9 is assembled and slidably mounted on the track 10 via the roller sleeve 9. The track 10 is mounted on the housing 12 via the track tie rod 11. Several sawn sections are provided on the track 10 between the track tie rods 11. The stabilizing bracket is mounted on the housing 12 on both sides of the track 10 cut and fixedly supports the track 10 at both ends of the cut. The horizontal detection device 20 can be mounted on the housing 12 outside the head wheel or tail wheel of the conveyor and the detection direction of the horizontal detection device 20 is always facing the positioning cursor 19 in the stabilizing bracket.

[0026] Furthermore, the stabilizing bracket also includes an L-shaped track rod 13, a mounting plate 14, a fastening bolt hole structure 15, a fixing groove 16, a roller 17, a 7-type positioning frame 18, and a cursor 19. The L-shaped track rod 13 and the roller 17 are both mounted on the housing 12 through the mounting plates 14 at both ends and the fastening bolt hole structure 15. The L-shaped track rod 13 is divided into two groups and installed on the left and right sides of the roller 17. The fixing groove 16 in the middle of the L-shaped track rod 13 supports and fixes the track 10 at both ends of the break. The 7-type positioning frame 18 is installed on the upper side of the mounting plate 14. The cursor 19 is glued to the crossbar on the upper side of the 7-type positioning frame 18. This structure can support the track 10 at both ends of the break through the L-shaped track rod 13. The L-shaped track rod 13 and the roller 17 are designed with an easy-to-disassemble mounting structure, which facilitates quick disassembly and use.

[0027] Furthermore, the upper surface of the idler roller 17 is 2-5 mm higher than the upper surface of the track 10. This design allows the idler roller 17 to provide support for the chain plate, and the idler roller 17 can rotate freely with the movement of the chain plate. This breaks the vicious cycle of increasing swaying friction, reduces the sliding friction between the chain plate and the track 10, and extends the service life of the track 10.

[0028] Furthermore, the cursor 19 adopts a square film structure, and a circular target-shaped reflective patch is set on the lower right corner of the square film near the outer side of the outer chain plate 7. The reflective patch of this structure can reflect the infrared light emitted by the laser rangefinder, so that it can receive feedback signals in time. Under normal circumstances, when the distance measured by the laser rangefinder remains unchanged for a long time, it proves that the outer chain plate 7 has no further shaking after slight shaking. However, when the outer chain plate 7 shakes too much, the distance measured by the laser rangefinder will fluctuate due to the influence of the floating outer chain plate 7. At this time, the inspection personnel can stop the machine for maintenance.

[0029] Furthermore, the level detection device 20 can be a laser rangefinder.

[0030] The working principle of this utility model:

[0031] The device can install stabilizing brackets in several sections of the track 10 as needed, and provide support for the chain plate through the idler rollers 17 in the stabilizing brackets. The idler rollers 17 can rotate freely with the movement of the chain plate, thus breaking the vicious cycle of increasing shaking friction and reducing the sliding friction between the chain plate and the track 10. This improves the reliability of equipment operation. At the same time, the horizontal detection device 20 installed on the outer casing 12 of the conveyor head wheel or tail wheel can detect whether the outer chain plate 7 is shaking or has a risk of tipping by aligning with the circular reflective patch. This allows the staff to conveniently perform regular inspections without opening the casing 12.

[0032] After practical application, the following optimizations can be achieved:

[0033] 1. Reduce the maintenance frequency of the two chain conveyors from 7-10 days / time, 6 hours / time to 90 days / time, 2 hours / time. Based on an average cost of approximately 1,000 yuan per maintenance, this will save 48,000 yuan annually.

[0034] 2. Reduce the cost of grinding and leveling the track 10, replacing worn roller sleeves 9, and repairing damaged transmission components by scraping, saving 50,000 yuan per year;

[0035] 3. Reduces average annual maintenance time by 316 hours, decreasing the workload and exposure time of equipment maintenance personnel to operational risks;

[0036] 4. Improve equipment reliability, avoid frequent downtime, simplify operating procedures, and reduce the labor intensity and operational difficulty for employees.

[0037] From this, the inventor drew the following conclusion:

[0038] 1. The application of this device optimizes the performance of production equipment, significantly reduces inherent defects in equipment design, improves the essential efficiency of equipment, extends equipment operating time, reduces severe wear and tear and the frequency and duration of maintenance, saves repair material costs, and also achieves the effect of reducing consumption.

[0039] 2. It increased the operating rate of the heavy calcium carbonate plant, increased output, and directly generated economic benefits;

[0040] 3. Reduced the workload and exposure time to operational risks for equipment maintenance personnel;
