Description

Technical Field

[0001] This application relates to the field of track stop technology, and in particular to a track stop structure for a belt conveyor. Background Technology

[0002] A material handling trolley is a material transfer device that runs on a factory track. It is mainly used for conveying bulk materials and unloading them at designated points between different workstations. It typically consists of a frame, a traveling mechanism, and an unloading device. It travels along a pre-set track and can achieve automated or manual control of start-up, shutdown, and unloading operations. Due to its simple structure and convenient operation, it is widely used in continuous production systems in industries such as metallurgy, mining, building materials, and chemicals.

[0003] However, most unloading trolleys have relatively simple control systems, typically only having travel and stop functions, lacking comprehensive fault detection and safety protection devices. In actual operation, if the unloading trolley drive system malfunctions while the conveyor belt continues to run, the belt may pull the unloading trolley along its running direction, causing the trolley to move uncontrollably. Once the unloading trolley is carried away from its original working position by the belt, its speed will gradually synchronize with the belt, eventually impacting the stop at the end of the track at a high speed. Such impacts often damage the stop structure, and in severe cases, may even cause the unloading trolley to derail and overturn, damaging not only the trolley itself but also potentially causing serious damage to the belt conveyor system and related equipment, affecting production safety and efficiency. Utility Model Content

[0004] To address the problem of high-speed impacts easily damaging the stopper, this application provides a belt conveyor track stopper structure.

[0005] The technical solution for the belt conveyor track stop structure provided in this application is as follows:

[0006] A belt conveyor track stop structure includes a stop body and a buffer block. A connecting block is detachably mounted on the side of the stop body near the buffer block. A buffer structure is provided between the connecting block and the buffer block. A first working groove and a second working groove for mounting the buffer mechanism are respectively opened on opposite sides of the connecting block and the buffer block. The buffer structure includes two first sliders, a first sliding rod, two second sliders, a second sliding rod, and two rotating rods. The first sliding rods are connected to the inner wall of the first working groove. Both first sliders are slidably connected to the first sliding rods, and a first spring is provided between the two first sliders. The second sliding rods are connected to the inner wall of the second working groove. Both second sliders are slidably connected to the second sliding rods, and a third spring is provided between each of the two second sliders and the inner wall of the second working groove. The two rotating rods correspond to the first and second sliders on the same side, and their two ends are rotatably connected to the corresponding first and second sliders.

[0007] As the unloading trolley is carried away from its original working position by the belt, its speed will gradually synchronize with the belt, eventually impacting the stop at the end of the track at a high speed. Such impacts often damage the stop structure, and in severe cases, may even cause the unloading trolley to derail and overturn, damaging not only the trolley itself but also potentially causing serious damage to the belt conveyor system and related equipment, affecting production safety and efficiency. By adopting the above technical solution, including the stop body and the buffer block, the connecting block is installed on one side of the stop body, and the buffer structure is installed between the connecting block and the buffer block. The buffer structure includes two first sliders, a first slide rod, two second sliders, a second slide rod, and two rotating rods.

[0008] When the trolley travels beyond its limits and impacts the buffer block, the impact force in the vertical direction acts on the buffer block first, pushing it to move closer to the connecting block. The movement of the buffer block transmits force through the V-shaped rotating rod. The rotation of the rotating rod drives the two first sliders to slide towards each other along the first sliding rod against the elastic force of the first spring, compressing the first spring. On the other hand, it drives the two second sliders to slide away from each other along the second sliding rod, compressing the third spring, thus achieving buffering and significantly attenuating the peak impact force. The impact energy of the trolley is effectively absorbed and dissipated, protecting the trolley, the stop structure, and the track foundation.

[0009] By incorporating connecting blocks, buffer blocks, and a buffer structure, this buffer structure can greatly absorb and disperse impact energy, transforming a potentially severe rigid impact into a gentle, flexible buffer. This effectively reduces the peak impact force borne by the stopper, prevents damage to the stopper structure, reduces the risk of the unloading trolley derailing or overturning, protects the safety of the unloading trolley and belt conveyor system, and ensures the safety of the entire production process.

[0010] Optionally, the number of buffer structures is two sets, and the number of first working slots and second working slots on the connecting block and the buffer block are two each. The two first working slots are respectively opened on the upper and lower surfaces of the connecting block, and the two second working slots are respectively opened on the upper and lower surfaces of the buffer block.

[0011] By adopting the above technical solution, there are two sets of buffer structures, with two first working slots and two second working slots on both the connecting block and the buffer block. By setting the number of buffer structures, the two sets of buffer structures form an upper and lower layout, which effectively avoids local stress concentration caused by uneven force. During the impact process, the two sets of buffer structures play a role at the same time, efficiently absorbing and dispersing the impact energy, further reducing the damage of the impact force to the stop, unloading trolley and related equipment, and extending the service life of the equipment.

[0012] Optionally, the two rotating rods in the same set of buffer structures are arranged in a V-shape.

[0013] By adopting the above technical solution, the two rotating rods in the same set of buffer structures are arranged in a V-shape. Through the arrangement of the rotating rods, the V-shaped arrangement of the rotating rods can efficiently convert and disperse the vertical impact force, guide the vertical impact force to the horizontal direction, enhance the buffer structure's ability to withstand vertical impacts, further absorb and dissipate impact energy, and achieve buffering.

[0014] Optionally, the first slide bar is provided with two first limiting rings, which are respectively arranged on the outer sides of the two first sliders facing away from each other.

[0015] By adopting the above technical solution, two first limiting rings are installed on the first slide rod; by setting the two first limiting rings, the two first limiting rings define the sliding boundary of the first slider, which can effectively limit the sliding stroke of the first slider on the first slide rod and ensure that the buffering function is stable and reliable.

[0016] Optionally, the second slide bar is provided with two second limiting rings, which are respectively arranged on the inner sides of the two second sliders facing each other.

[0017] By adopting the above technical solution, two second limiting rings are installed on the second slide rod; by setting the two second limiting rings, the sliding distance between the two second sliders can be effectively controlled, and the second sliders move within the preset safe travel range to maintain the stability of the buffering process.

[0018] Optionally, two hydraulic telescopic rods are provided between the connecting block and the buffer block, and the two hydraulic telescopic rods are symmetrically arranged on both sides of the connecting block.

[0019] By adopting the above technical solution, two hydraulic telescopic rods are installed between the connecting block and the buffer block. Through the setting of the hydraulic telescopic rods, the hydraulic oil inside the hydraulic telescopic rods flows through the throttling hole to generate damping force, which can absorb and dissipate a part of the impact kinetic energy, further reducing the damage of the impact force to the stop, unloading trolley and related equipment, and effectively extending the service life of the equipment.

[0020] Optionally, each of the two hydraulic telescopic rods is provided with a second spring, which is sleeved on the corresponding hydraulic telescopic rod.

[0021] By adopting the above technical solution, the second spring is sleeved on the corresponding hydraulic telescopic rod; through the setting of the second spring, the second spring provides elastic buffering force for the buffering process, complementing the damping buffering of the hydraulic telescopic rod, realizing a multi-level buffering effect, efficiently absorbing and dispersing impact energy, and further reducing the peak impact force.

[0022] Optionally, the stop body is provided with two fixed plates, and the connecting block is provided with two wing plates for cooperating with the fixed plates, with the two fixed plates corresponding one-to-one with the two wing plates.

[0023] By adopting the above technical solution, two fixed plates are installed on the stop body, and two wing plates are installed on the connecting block. The two wing plates are detachably connected to the two fixed plates. The detachable connection method of the fixed plates and wing plates facilitates maintenance or replacement, shortens equipment maintenance time, improves maintenance efficiency, and allows for flexible replacement of buffer modules with different performance according to actual conditions to meet diverse buffering needs.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By setting up connecting blocks, buffer blocks and buffer structures, the buffer structure can greatly absorb and disperse impact energy, transforming the rigid impact that could have caused serious damage into a gentle and flexible buffer, effectively reducing the peak impact force borne by the stopper, avoiding damage to the stopper structure, reducing the risk of derailment and overturning of the unloading trolley, protecting the safety of the unloading trolley and belt conveyor system, and ensuring the safety of the entire production process.

[0026] 2. By setting the rotating rod arrangement, the V-shaped rotating rod can efficiently convert and disperse the vertical impact force, guide the vertical impact force to the horizontal direction, enhance the buffer structure's ability to withstand vertical impact, further absorb and dissipate impact energy, and achieve buffering.

[0027] 3. By setting up the hydraulic telescopic rod, the hydraulic oil inside the hydraulic telescopic rod flows through the throttling hole to generate damping force, which can absorb and dissipate part of the impact kinetic energy, further reducing the damage of the impact force to the stop, unloading trolley and related equipment, and effectively extending the service life of the equipment.

[0031] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0032] This application discloses a track stop structure for a belt conveyor. (Refer to...) Figure 1 The belt conveyor track stop structure includes a stop body 1 and a buffer block 3. In this embodiment, a connecting block 2 is installed on the side of the stop body 1 near the buffer block 3. Two wing plates 16 are installed and fixed on the connecting block 2. Two fixing plates 17 are installed on the stop body 1. The two fixing plates 17 correspond one-to-one with the two wing plates 16. The wing plates 16 and the fixing plates 17 are fixed by bolts. The detachable connection method facilitates maintenance or replacement, shortens equipment maintenance time, and improves maintenance efficiency. Different buffer modules with different performance can be flexibly replaced according to the actual situation to meet diverse buffering needs.

[0033] Reference Figure 1 Two hydraulic telescopic rods 13 are installed between the connecting block 2 and the buffer block 3. The two hydraulic telescopic rods 13 are symmetrically arranged on both sides of the connecting block 2. The hydraulic oil inside the hydraulic telescopic rod 13 flows through the throttle hole to generate damping force, which can absorb and dissipate part of the impact kinetic energy, further reducing the damage of the impact force to the stop, unloading trolley and related equipment, and effectively extending the service life of the equipment.

[0034] Reference Figure 1 Each of the two hydraulic telescopic rods 13 is fitted with a second spring 12. The second spring 12 provides elastic buffering force during the buffering process, which complements the damping buffering of the hydraulic telescopic rods 13, achieving a multi-level buffering effect, efficiently absorbing and dispersing impact energy, and further reducing the peak impact force.

[0035] Reference Figure 1 and Figure 2 A buffer structure is installed between the connecting block 2 and the buffer block 3. The connecting block 2 and the buffer block 3 are respectively provided with a first working groove 4 and a second working groove 5 for the installation of the buffer mechanism. The buffer structure includes two first sliders 7, a first slide rod 6, two second sliders 9, a second slide rod 14 and two rotating rods 8. The first slide rod 6 is fixedly connected to the inner wall of the first working groove 4. The two first sliders 7 are slidably connected to the first slide rod 6. A first spring 11 is installed between the two first sliders 7.

[0036] Reference Figure 1 and Figure 2The second slide rod 14 is fixedly connected to the inner wall of the second working groove 5, and the two second sliders 9 are slidably connected to the second slide rod 14. A third spring 15 is installed between the two second sliders 9 and the inner wall of the second working groove 5. The two rotating rods 8 correspond to the first slider 7 and the second slider 9 on the same side, and the two ends of the rotating rods 8 are rotatably connected to the corresponding first slider 7 and the second slider 9. The two rotating rods 8 in the same set of buffer structures are arranged in a V-shape. The V-shaped rotating rods 8 can efficiently convert and disperse the vertical impact force, guide the vertical impact force to the horizontal direction, enhance the buffer structure's ability to withstand vertical impact, further absorb and dissipate impact energy, and achieve buffering.

[0037] Reference Figure 1 and Figure 2 Two first limiting rings 10 are installed on the first slide rod 6. The two first limiting rings 10 are respectively arranged on the outer sides of the two first sliders 7 opposite to each other. In this embodiment, the first limiting ring 10 is located at the end of the first slider 7 away from the corresponding first spring 11. The two first limiting rings 10 define the sliding boundary of the first slider 7, which can effectively limit the sliding stroke of the first slider 7 on the first slide rod 6 and ensure that the buffering function is stable and reliable.

[0038] Reference Figure 1 and Figure 2 Two second limiting rings 18 are installed on the second slide rod 14. The two second limiting rings 18 are respectively arranged on the inner side of the two second sliders 9 opposite to each other. In this embodiment, the second limiting rings 18 are located at the end of the second slider 9 away from the corresponding second spring 12. The second spring 12 provides elastic buffering force for the buffering process, which complements the damping buffer of the hydraulic telescopic rod 13, realizes multi-level buffering effect, efficiently absorbs and disperses impact energy, and further reduces the peak impact force.

[0039] Reference Figure 1 In this embodiment, there are two sets of buffer structures. There are two first working grooves 4 and two second working grooves 5 on both the connecting block 2 and the buffer block 3. The two first working grooves 4 are respectively opened on the upper and lower surfaces of the connecting block 2, and the two second working grooves 5 are respectively opened on the upper and lower surfaces of the buffer block 3. The two sets of buffer structures form an upper and lower layout, which effectively avoids local stress concentration caused by uneven force. During the impact process, the two sets of buffer structures play a role at the same time, efficiently absorbing and dispersing the impact energy, further reducing the damage of the impact force to the stop, unloading trolley and related equipment, and extending the service life of the equipment.

[0040] The implementation principle of the belt conveyor track stop structure in this application embodiment is as follows: When the trolley travels beyond the limit and impacts the buffer block 3, the trolley travels beyond the limit and directly impacts the buffer block 3. The vertical impact force first acts on the buffer block 3, pushing the buffer block 3 to move closer to the connecting block 2. At this time, the piston rod of the hydraulic telescopic rod 13 is compressed, and the hydraulic oil inside the hydraulic telescopic rod 13 generates damping force to absorb part of the impact energy. At the same time, the second spring 12 is compressed, storing elastic potential energy and assisting in buffering, forming the first stage of buffering against the vertical impact force. Subsequently, the movement of the buffer block 3 transmits force through the V-shaped rotating rod 8. The rotation of the rotating rod 8 drives the two first sliders 7 along the first... The slide bar 6 overcomes the elastic force of the first spring 11 and slides towards each other, compressing the first spring 11. On the other hand, it drives the two second sliders 9 to slide away from each other along the second slide bar 14, compressing the third spring 15. The first limiting ring 10 and the second limiting ring 18 ensure that the sliders move within the limited stroke of the slide bar to prevent them from coming off. This process efficiently converts and disperses the remaining vertical impact kinetic energy into the compression deformation of the first spring 11 and the tensile deformation of the third spring 15, that is, the spring deformation in the horizontal direction, to achieve the second-level buffer and significantly attenuate the peak impact force. Finally, through the multi-level and multi-directional synergistic action of hydraulic damping, spring compression, and tension, the impact energy of the trolley is effectively absorbed and dissipated, protecting the trolley, the stop structure, and the track foundation.

[0041] By setting up connecting block 2, buffer block 3 and buffer structure, the buffer structure can greatly absorb and disperse impact energy, transforming the rigid impact that could have caused serious damage into a gentle flexible buffer, effectively reducing the peak impact force borne by the stopper, avoiding damage to the stopper structure, reducing the risk of derailment and overturning of the unloading trolley, protecting the safety of the unloading trolley and belt conveyor system, and ensuring the safety of the entire production process.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
