[0004] The setting of existing suspension conveyors usually needs to be reasonably designed according to the work site. Therefore, suspension conveyors usually have obvious uphill and downhill structures. When the suspension conveyor travels to the uphill and downhill areas and the movement state changes significantly, the load will have a certain impact on itself. Once the suspension conveyor is subjected to excessive load impact for a long time, causing its own structure to change until it is damaged, it is very easy to cause damage to the overall structure of the suspension track, affecting the normal use of the suspension conveyor. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that once the suspension conveyor is subjected to excessive load impact for a long time, causing its own structure to change or even be damaged, it is very easy to cause damage to the overall structure of the suspension track, affecting the normal use of the suspension conveyor.

[0006] In order to solve the above problems, the present invention provides a high-strength anti-impact suspension structure for a conveyor, comprising a plurality of conveying units arranged on a conveying track, wherein the plurality of conveying units each comprises a bracket and a pair of transmission wheels respectively connected to the conveying track for rotation, the transmission wheels are connected to the bracket for rotation, a power lock is arranged on the lower side of the conveying track, the power lock penetrates through the plurality of brackets and is fixedly connected to the bracket, an anti-impact unit is fixedly connected to one end of the bracket away from the conveying track, and a load is fixedly connected to the lower end of the anti-impact unit; The anti-impact unit includes a movable tube body, a movable cavity is bored in the movable tube body, a main force-bearing unit is slidably connected to the movable cavity, and the lower end of the main force-bearing unit passes through the movable tube body and extends to the outside of the movable tube body, the main force-bearing unit includes a main movable rod, the upper end of the main movable rod is fixedly connected to a main T-head matching the shape of the movable cavity, a plurality of main through holes are bored in the main T-head, and the plurality of main through holes completely penetrate the main T-head, a main compression spring is sleeved on the outer side of the main movable rod, and the two ends of the main compression spring are respectively fixedly connected to the main T-head and the inner wall of the movable cavity, a secondary cavity is bored at the lower end of the main movable rod, a secondary force-bearing unit is slidably connected in the secondary cavity, a secondary compression spring is sleeved on the outer side of the secondary force-bearing unit, and the two ends of the secondary compression spring are respectively fixedly connected to the secondary force-bearing unit and the secondary cavity, the elastic coefficient of the secondary compression spring is smaller than the elastic coefficient of the main compression spring, the inner wall of the secondary cavity is fixedly connected to a limiting ring, the lower end of the limiting ring is fixedly connected to a storage unit 1, and the storage unit 1 is filled with air-hardening gel material.

[0007] In the high-strength impact-resistant suspension structure for the above-mentioned conveyor, the impact generated during the load transportation process is buffered by the main compression spring and the secondary compression spring with different elastic coefficients, and through the cooperation of the limit ring and the storage unit 1, the overloaded conveying unit during the operation can be marked in time, so that the staff can judge the current working safety level of the suspended conveyor.

[0008] As a further improvement of the present application, the active cavity is filled with hydraulic oil, and the main through hole is an inclined hole. The main through hole design using hydraulic oil and the inclined hole can increase the damping of the main force-bearing unit moving in the active cavity, increase the stability of the main force-bearing unit moving, and prevent the load from shaking too much during transportation.

[0009] As a further improvement of the present application, the outer wall of the secondary force-bearing unit away from the limiting ring is coated with fluorescent pigment. When the secondary force-bearing unit breaks the limiting ring, the secondary force-bearing unit coated with fluorescent pigment will leak out, making it easier for staff to find the overloaded conveying unit in time.

[0010] As a further improvement of the present application, a replacement unit is threadedly connected at the opening of the secondary cavity, and the replacement unit includes a tube body, the upper part of the tube body is a limiting part, the lower part of the tube body is a connecting part, and a storage unit 2 is fixedly connected to the inner wall of the tube body. The storage unit 2 is filled with the same air-hardening gel material as that of the storage unit 1. When the conveying unit is overloaded and the replacement unit is damaged, the replacement unit can be directly replaced.

[0011] As another improvement of the present application, a prefabricated groove is bored on the outer wall of the tube body, and the prefabricated groove is located in the middle position of the tube body. When the replacement unit is compressed by the secondary force-bearing unit, the stress is concentrated at the prefabricated groove, so that the tube body is sunken as a whole, and the limiting part and the connecting part are not prone to excessive deformation, which facilitates the subsequent removal of the replacement unit.

[0012] As another improved supplement of the present application, a plurality of installation grooves are drilled on the connecting portion of the tube body to facilitate the removal of the replacement unit.

[0013] As another improvement supplement of the present application, a plurality of elastic fibers are mixed in the aerohardening gel material, and the plurality of elastic fibers are in a three-dimensional spiral shape. Adjacent elastic fibers are entangled with each other. The elastic fibers are utilized to increase the strength of the solidified aerohardening gel material, making it less likely to break and fail under the action of external forces.

[0014] In summary, the impact generated during the load transportation process is buffered by the main compression spring and secondary compression spring with different elastic coefficients. The secondary compression spring with a smaller elastic coefficient has a better buffering effect, while the main compression spring with a larger elastic coefficient has a slightly worse buffering effect. The two cooperate with each other to adapt to the impact of different loads and the changes in motion state during transportation, thereby reducing the impact on the conveying unit during movement. Furthermore, through the cooperation of the limit ring and the storage unit, the overloaded conveying unit during work can be marked in time, so that the staff can judge the current working safety level of the suspended conveyor.

[0015] At the same time, the replacement unit is used to replace the limit ring and the storage unit. When the conveying unit is overloaded and the replacement unit is damaged, the replacement unit can be directly replaced, so that the conveying unit can be retained as a whole, the maintenance operation is convenient, and it is easy to keep the normal operation of the conveyor.

DETAILED DESCRIPTION

[0018] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0019] The first implementation method: Figure 1 A high-strength anti-impact suspension structure for a conveyor is shown, comprising a plurality of conveying units arranged on a conveying track 1, wherein each of the plurality of conveying units comprises a bracket 3 and a pair of transmission wheels 2 respectively rotatably connected to the conveying track 1, wherein the transmission wheels 2 are rotatably connected to the bracket 3, a power lock 4 is arranged on the lower side of the conveying track 1, the power lock 4 penetrates through the plurality of brackets 3 and is fixedly connected to the bracket 3, wherein the power lock 4 is connected to a power unit to drive the conveying unit to move along the conveying track 1, and the power unit can select various types of motors according to actual conditions, an anti-impact unit 5 is fixedly connected to one end of the bracket 3 away from the conveying track 1, and a load 12 is fixedly connected to the lower end of the anti-impact unit 5; See also Figure 2-5The impact-resistant unit 5 includes a movable tube body 501, a movable cavity 502 is excavated in the movable tube body 501, and the movable cavity 502 is slidably connected to the main force-bearing unit 6, and the lower end of the main force-bearing unit 6 passes through the movable tube body 501 and extends to the outside of the movable tube body 501. The main force-bearing unit 6 includes a main movable rod 601, and the upper end of the main movable rod 601 is fixedly connected to a main T-head 602 that matches the shape of the movable cavity 502, and the main T-head 602 is excavated with a plurality of main through holes 603, and the plurality of main through holes 603 completely penetrate the main T-head 602. The outer side of the main movable rod 601 is sleeved with a main compression spring 7, and the two ends of the main compression spring 7 are respectively connected to the main T-head 602 and the movable tube body 501. The inner wall of the cavity 502 is fixedly connected, and a secondary cavity 604 is excavated at the lower end of the main movable rod 601. A secondary force-bearing unit 8 is slidably connected in the secondary cavity 604. The basic structure of the secondary force-bearing unit 8 is similar to that of the main force-bearing unit 6, except that the lower end of the secondary force-bearing unit 8 is a solid structure. A secondary compression spring 9 is sleeved on the outer side of the secondary force-bearing unit 8, and the two ends of the secondary compression spring 9 are respectively fixedly connected to the secondary force-bearing unit 8 and the secondary cavity 604. The elastic coefficient of the secondary compression spring 9 is smaller than the elastic coefficient of the main compression spring 7. The inner wall of the secondary cavity 604 is fixedly connected to a limiting ring 10, and the lower end of the limiting ring 10 is fixedly connected to a storage unit 11, and the storage unit 11 is filled with air-hardening gel material.

[0020] See also Figure 6 In the process of transporting the load 12, the main compression spring 7 and the secondary compression spring 9 cooperate to solve the impact resistance requirements in the uphill and downhill stages of the conveying track 1 and the loading stage of the load 12. When the impact resistance unit 5 is impacted, the secondary compression spring 9 with a smaller elastic coefficient will first undergo elastic deformation under the action of external force until the movement of the secondary force-bearing unit 8 is limited by the limit ring 10. At this time, the main compression spring 7 with a larger elastic coefficient will undergo elastic deformation and continue to resist external impact. When the main compression spring 7 is elastically deformed to the limit, the impact resistance When the impact on the impact unit 5 continues to increase, the external impact will cause the secondary force unit 8 to move further downward, break the limit ring 10, and break the storage unit 11, squeeze out the air-hardening gel material stored in the storage unit 11, and quickly solidify in the air, so that the secondary force unit 8 and the main force unit 6 are relatively fixed. When the load 12 is unloaded, the staff can observe whether the secondary force unit 8 can return to the main force unit 6 in time to determine whether the current load 12 is overloaded, and determine the current operating status of the suspension conveyor according to the overload frequency.

[0021] In the present application, the impact generated during the transportation of the load 12 is buffered by the main compression spring 7 and the secondary compression spring 9 with different elastic coefficients. The secondary compression spring 9 with a smaller elastic coefficient has a better buffering effect, while the main compression spring 7 with a larger elastic coefficient has a slightly worse buffering effect. The two cooperate with each other to adapt to the load 12 of different loads and the impact caused by the change of motion state during its transportation, thereby reducing the impact on the conveying unit during the movement. Furthermore, through the cooperation of the limit ring 10 and the storage unit 11, the overloaded conveying unit during the operation process can be marked in time, so that the staff can judge the current working safety level of the suspended conveyor.

[0022] The active cavity 502 is filled with hydraulic oil, and the main through hole 603 is an inclined hole. The design of the main through hole 603 using hydraulic oil and the inclined hole can increase the damping of the main force-bearing unit 6 moving in the active cavity 502, increase the stability of the movement of the main force-bearing unit 6, and prevent the load 12 from shaking too much during transportation.

[0023] The outer wall of the secondary force-bearing unit 8 away from the limiting ring 10 is coated with fluorescent pigment. When the secondary force-bearing unit 8 breaks the limiting ring 10, the secondary force-bearing unit 8 coated with the fluorescent pigment will leak out, which is convenient for the staff to find the overloaded conveying unit in time. The coating position of the secondary force-bearing unit 8 can be designed by technical personnel in this field according to the specific dimensions of the impact-resistant unit 5, the main force-bearing unit 6, and the secondary force-bearing unit 8. It is a well-known technology to technical personnel in this field, so it is not set in detail in this social situation.

[0024] The second implementation method: Figure 7-10 A high-strength impact-resistant suspension structure for a conveyor is shown, a replacement unit 13 is threadedly connected at the opening of the secondary cavity 604, the replacement unit 13 is used to replace the limiting ring 10 and the storage unit 11, the replacement unit 13 includes a tube body 1301, the upper part of the tube body 1301 is a limiting part, the lower part of the tube body 1301 is a connecting part, wherein the limiting part is used to limit the movement range of the secondary force-bearing unit 8, and the connecting part is the position where the replacement unit 13 is threadedly connected to the secondary cavity 604, the inner wall of the tube body 1301 is fixedly connected to the storage unit 2 1303, and the storage unit 2 1303 is filled with the same air-hardening gel material as the storage unit 11.

[0025] In the present embodiment, by replacing the fixed limit ring 10 and storage unit 11 in the first embodiment with a replaceable replacement unit 13, when the conveying unit is overloaded and the replacement unit 13 is damaged, the replacement unit 13 can be directly replaced, and the bonding problem caused by the solidification of the aero-hardening gel material can be handled during replacement according to its type. For example, when 502 glue is selected as the aero-hardening gel material, the viscosity of the 502 glue can be reduced by heating treatment, and then the damaged replacement unit 13 can be taken out, so that the conveying unit can be retained as a whole, the maintenance operation is convenient, and it is easy to keep the conveyor working normally. However, compared with the limit ring 10 and storage unit 11 of the first embodiment, the manufacturing cost of the replacement unit 13 is significantly increased, and technical personnel in this field need to select it according to actual conditions.

[0026] A prefabricated groove 1302 is bored on the outer wall of the tube body 1301, and the prefabricated groove 1302 is located in the middle position of the tube body 1301. When the replacement unit 13 is compressed by the secondary force-bearing unit 8, the stress is concentrated in the prefabricated groove 1302, so that the tube body 1301 is sunken as a whole, and the limiting part and the connecting part are not prone to excessive deformation, which facilitates the subsequent removal of the replacement unit 13.

[0027] A plurality of mounting grooves 1305 are formed on the connecting portion of the tube body 1301 to facilitate the removal of the replacement unit 13 .

[0028] The aerohardening gel material is doped with a plurality of elastic fibers 1304, each of which is in a three-dimensional spiral shape. Adjacent elastic fibers 1304 are entangled with each other. The elastic fibers 1304 are used to increase the strength of the cured aerohardening gel material, making it less likely to break and fail under external forces.

[0029] Compared with the first embodiment, in this embodiment, the limit ring 10 and the storage unit 11 are replaced by the replacement unit 13. When the conveying unit is overloaded and the replacement unit 13 is damaged, the replacement unit 13 can be directly replaced, so that the conveying unit can be retained as a whole, the maintenance operation is convenient, and it is easy to keep the normal operation of the conveyor.

[0030] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
