Description

Technical Field

[0001] This invention belongs to the technical field of belt conveyor equipment, and specifically relates to a windproof and earthquake-resistant belt conveyor support structure for a shallow circular warehouse trestle. Background Technology

[0002] Shallow circular silos, as the primary storage facilities for bulk materials such as grain and coal, rely on their trestle bridges as the crucial link between the silo body and the conveyor system. The belt conveyor supports are the core load-bearing structure for material transport within the trestle bridges. In practical applications, shallow circular silos are often built in open environments, and the trestle bridges are frequently located in open areas, making them susceptible to the effects of strong winds, gusts, and other meteorological factors. Simultaneously, some areas may experience seismic activity, or secondary vibrations may occur due to impacts during material transport or equipment operation. These factors place stringent demands on the stability and safety of the belt conveyor supports.

[0003] Existing conveyor belt supports for shallow circular silo trestle bridges are mostly fixed rigid structures, which have several drawbacks: First, they lack wind resistance. The large exposed area of ​​the conveyor belt in fixed structures makes them susceptible to significant wind loads under strong winds, causing the supports to sway, shift, or even the belt to run off course or detach, affecting the continuity of conveying operations. Second, they have weak seismic resistance. Rigid supports cannot effectively buffer vibration energy, and the vibration is directly transmitted to the main body and connecting parts of the support. Long-term use can easily lead to structural fatigue and weld cracking, posing safety hazards. Third, they have poor adaptability. Fixed structures cannot adjust the length and angle of the conveyor belt, making it difficult to adapt to the material transfer needs of shallow circular silos of different heights. Furthermore, the supports are inconvenient to move, requiring significant manpower and resources for disassembly or transportation during maintenance. Fourth, their locking stability is insufficient. Existing locking mechanisms for mobile supports are mostly fixed in one direction, making them prone to loosening under wind loads or vibrations, failing to guarantee the reliability of the support's positioning. To address these problems, this invention provides a windproof and seismic-resistant conveyor belt support structure for shallow circular silo trestle bridges. Summary of the Invention

[0004] To address the aforementioned technical problems, the technical solution adopted by this invention is: a windproof and earthquake-resistant belt conveyor support structure for a shallow circular warehouse trestle, the support structure comprising: A base plate, on which a conveyor belt is arranged, the conveyor belt being driven to rotate by a motor; The folding mechanism is installed above the base plate. The folding mechanism includes two symmetrically arranged second support plates. One end of the second support plate is rotatably connected to the first support plate. A plurality of second support rollers are arranged between the two second support plates. The second support rollers are connected to the conveyor belt. An anti-seismic mechanism is installed between two second support plates. The anti-seismic mechanism includes a counterweight. When the base plate shakes, the inertia of the counterweight counteracts the external force that causes the base plate to shake. The locking mechanism comprises four parts, which are respectively arranged at the four corners of the base plate. The locking mechanism is used to improve the stability of the base plate in contact with the ground.

[0005] Furthermore, two rows of symmetrically arranged columns are fixedly installed above the base plate, a first support plate is fixedly installed on the columns, and a plurality of linearly arranged first support rollers are installed on the first support plate. The first support rollers are connected to the conveyor belt, and the motor is fixedly installed on the first support plate.

[0006] Furthermore, the folding mechanism also includes two sets of symmetrically arranged support rods. Each set of support rods includes multiple support rods arranged linearly. The lower end of each support rod is slidably engaged with the base plate, and the upper end of each support rod is slidably engaged with a second support rod. The second support rod is rotatably connected to a slider. The slider is slidably engaged with a guide groove on the second support plate. When the second support plate rotates relative to the first support plate, the slider slides along the guide groove.

[0007] Furthermore, the folding mechanism also includes a threaded block, which slides with the base plate and forms a threaded engagement with a lead screw rotatably mounted on the base plate. The threaded block slides with the upper rod above it, and the upper rod is fixedly connected to the crossbeam. The two ends of the crossbeam slide with rectangular grooves on the two support rods.

[0008] Furthermore, the anti-seismic mechanism also includes a sliding rod 1, the two ends of which are slidably engaged with rectangular grooves on two support rods 2, the two ends of which are rotatably connected to one end of two rotating arms, the other end of which is rotatably connected to the sliding rod 2, the two ends of which are slidably engaged with guide grooves 2 on two second support plates, and the sliding rod 2 is rotatably connected to a counterweight.

[0009] Furthermore, the guide groove one and guide groove two are located on two adjacent and mutually perpendicular surfaces of the second support plate.

[0010] Furthermore, the locking mechanism includes two locking components arranged at ninety degrees. Each locking component includes a support base, which is rotatably mounted on a base plate. A movable wheel is rotatably mounted on the support base, and a positioning plate is fixedly mounted on the support base.

[0011] Furthermore, a gear is coaxially fixedly installed on the support base, the gear meshes with a rack, the rack is slidably installed on the base plate, and the two racks are connected by a drive assembly.

[0012] Furthermore, the drive assembly includes a cylinder fixedly mounted on the base plate. The extended end of the cylinder is rotatably connected to one end of a drive rod, and the other end of the drive rod is rotatably connected to a first push rod. The first push rod is rotatably connected to a second push rod, and the second push rod is slidably engaged with a straight groove on the base plate. The first push rod is slidably engaged with a guide rod, and the guide rod is fixedly mounted on a housing. The housing is fixedly mounted on the base plate. One end of a connecting rod is rotatably mounted on the first push rod. The other end of the connecting rod is slidably engaged with an optical axis fixedly mounted on the base plate, and the optical axis is slidably engaged with a connecting arm. A return spring is sleeved on the outer ring of the optical axis, and the connecting arm is fixedly connected to a rack away from the cylinder.

[0013] Furthermore, the locking component also includes a "T" shaped groove, which is composed of interconnected vertical and horizontal grooves.

[0014] The beneficial effects of this invention compared with the prior art are: (1) This invention uses a folding mechanism, an anti-vibration mechanism, a locking mechanism, a base plate, and a conveyor belt to form a support for the belt conveyor, which greatly improves the anti-vibration capability and stability of the support and effectively meets the usage requirements; (2) By setting a folding structure, the length of the conveyor belt in the horizontal direction can be adjusted during anti-vibration, and the center of gravity of the support can be adjusted to better cope with the vibration damage caused by wind to the support; and even in the absence of wind, the angle of the conveyor belt can be adjusted to meet the usage requirements of shallow circular silos of different heights; (3) By setting a locking mechanism, the base plate can be firmly fixed to the ground according to the actual usage scenario, or the base plate can be easily moved on the ground to move the entire support, which is highly practical.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0029] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in sequences other than those illustrated or described herein.

[0030] Example: Figure 1 — Figure 12 The diagram shows a windproof and earthquake-resistant belt conveyor support structure for a shallow circular warehouse trestle. The support structure includes a base plate 1, with a conveyor belt 4 arranged above the base plate 1. The conveyor belt 4 is driven to rotate by a motor 6.

[0031] Specifically, the conveyor belt 4 is driven by two rotating shafts, one of which is fixedly connected to the output shaft of the motor 6, and the motor 6 drives the rotating shaft and the conveyor belt 4 to rotate.

[0032] The folding mechanism is installed above the base plate 1. The folding mechanism includes two symmetrically arranged second support plates 7. One end of the second support plate 7 is rotatably connected to the first support plate 3. A plurality of second support rollers 8 are arranged between the two second support plates 7. The second support rollers 8 are connected to the conveyor belt 4.

[0033] The folding mechanism can adjust the length of the conveyor belt 4 in the horizontal direction, reducing the risk of damage caused by vibration when blown by the wind. Because if the conveyor belt 4 is kept in an extended state, the area exposed to wind along the length of the base plate 1 will increase, and the resulting vibration will be aggravated. Therefore, the vibration can be reduced by adjusting the length of the conveyor belt 4.

[0034] The seismic-resistant mechanism is installed between the two second support plates 7. The seismic-resistant mechanism includes a counterweight 22. When the base plate 1 shakes, the inertia of the counterweight 22 counteracts the external force that causes the base plate 1 to shake. The external force is the blowing force of the wind.

[0035] The locking mechanism consists of four parts, which are respectively arranged at the four corners of the base plate 1. The locking mechanism is used to improve the stability of the base plate 1 in contact with the ground.

[0036] The locking mechanism can improve the stability of the contact between the base plate 1 and the ground, reduce the shaking amplitude of the base plate 1 when vibration occurs, and allow the base plate 1 to move normally during normal use.

[0037] Two rows of symmetrically arranged columns 2 are fixedly installed above the base plate 1. A first support plate 3 is fixedly installed on the column 2. A number of first support rollers 5 arranged linearly are installed on the first support plate 3. The first support rollers 5 are connected to the conveyor belt 4. A motor 6 is fixedly installed on the first support plate 3.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 5As shown, two rows of columns 2 are arranged on the base plate 1, with multiple columns 2 in each row arranged linearly. Two first support plates 3 are respectively installed above the two rows of columns 2. One rotating shaft is rotatably installed between the two first support plates 3, and another rotating shaft is rotatably installed between the two second support plates 7. The two rotating shafts are located at both ends of the conveyor belt 4. Multiple first support rollers 5 are arranged between the two first support plates 3 to support the conveyor belt 4. To improve the rotation of the conveyor belt 4, a rotating roller can be installed at the end of the first support roller 5 that contacts the conveyor belt 4, thereby supporting the conveyor belt 4 while reducing friction. Similarly, a rotating roller can also be installed at the end of the second support roller 8 that contacts the conveyor belt 4. The connection method between the second support roller 8 and the second support plate 7 is the same as the connection direction between the first support plate 3 and the first support roller 5.

[0039] When motor 6 starts, the output shaft of motor 6 drives the rotating shaft to rotate, and the conveyor belt 4 connected to the rotating shaft will rotate. At this time, both rotating shafts and the conveyor belt 4 will rotate.

[0040] The folding mechanism also includes two sets of symmetrically arranged support rods 13. Each set of support rods 13 includes multiple support rods 13 arranged linearly. The lower end of the support rod 13 is slidably engaged with the base plate 1, and the upper end of the support rod 13 is slidably engaged with the second support rod 14. The second support rod 14 is rotatably connected to the slider 16. The slider 16 is slidably engaged with the guide groove 17 on the second support plate 7. When the second support plate 7 rotates relative to the first support plate 3, the slider 16 slides along the guide groove 17.

[0041] like Figure 1 , Figure 3 , Figure 5 , Figure 7 , Figure 8 As shown, when vibrations are generated by wind, the length of the conveyor belt 4 can be adjusted to mitigate the vibration. Specifically, both rows of support rods 13 can slide towards the side closer to the motor 6 along the base plate 1. Support rod 13 and support rod 2 14 slide in cooperation. At this time, support rod 2 14 will slide upward relative to support rod 13, and the slider 16 above support rod 2 14 will slide along the guide groove 17. Driven by support rod 2 14 and slider 16, the second support plate 7 will rotate relative to the first support plate 3, and the rotation direction is along... Figure 5 The direction N shown in the figure causes a change in angle between the second support plate 7 and the first support plate 3, which shortens the projected length of the conveyor belt 4 in the horizontal direction and reduces the wind force in the horizontal direction.

[0042] After the wind stops blowing, the support rod 13 and the second support plate 7 can be reset, allowing the conveyor belt 4 to return to its original position. Figure 1The state of the conveyor belt 4; of course, in order to expand the application scenarios of the conveyor belt 4, even without wind, the angles of the first support plate 3 and the second support plate 7 can be adjusted to adjust the conveying angle of the conveyor belt 4 to meet different usage requirements.

[0043] The folding mechanism also includes a threaded block 11, which is slidably engaged with the base plate 1. The threaded block 11 is threadedly engaged with the lead screw 10 rotatably mounted on the base plate 1. The upper part of the threaded block 11 is slidably engaged with the upper rod 12. The upper rod 12 is fixedly connected to the crossbeam. The two ends of the crossbeam are slidably engaged with the rectangular grooves 15 on the two support rods 14.

[0044] like Figure 3 , Figure 4 , Figure 5 , Figure 7 As shown, the movement of the drive support rod 13 can be achieved by rotating the handwheel 9. Specifically, the handwheel 9 is fixedly connected to the lead screw 10. When the handwheel 9 is rotated, the lead screw 10 will rotate on the base plate 1. At this time, the threaded block 11, which forms a threaded engagement with the lead screw 10, will slide along the base plate 1. The upper rod 12 above the threaded block 11 will slide relative to the threaded block 11. The crossbeam above the upper rod 12 will slide along the rectangular groove 15 and push the support rod 14, which in turn drives the second support plate 7 to rotate. The remaining support rods 13 and 14 follow suit.

[0045] The seismic-resistant mechanism also includes a sliding rod 19. Both ends of the sliding rod 19 are slidably engaged with rectangular grooves 15 on two support rods 14. Both ends of the sliding rod 19 are rotatably connected to one end of each of two rotating arms 20. The other end of each rotating arm 20 is rotatably connected to a sliding rod 21. Both ends of the sliding rod 21 are slidably engaged with guide grooves 18 on two second support plates 7. The sliding rod 21 is rotatably connected to a counterweight 22. Guide grooves 17 and 18 are located on two adjacent and mutually perpendicular surfaces of the second support plate 7.

[0046] like Figure 1 , Figure 2 , Figure 6 , Figure 7 As shown, by setting a counterweight 22, the wind force can be resisted, thereby achieving shock absorption. Specifically, the counterweight 22 is rotatably connected to the sliding rod 21, meaning that the counterweight 22 can swing relative to the sliding rod 21, rather than rotating in place. During the swinging process, the counterweight 22 will swing back and forth between the two rows of support rods 14. The inertia and swing of the counterweight 22 resist the wind force on the conveyor belt 4, thereby achieving shock absorption.

[0047] After adjusting the angles of the second support plate 7 and the first support plate 3, especially during the rotation along the N direction, the sliding rod 19 will slide along the rectangular groove 15, thereby pushing the rotating arm 20 through the sliding rod 19, so that the rotating arm 20 drives the sliding rod 21 and the counterweight 22 to slide along the guide groove 18 towards the side closer to the motor 6, adjusting the center of gravity and improving the shock absorption effect.

[0048] The locking mechanism includes two locking components arranged at ninety degrees. Each locking component includes a support base 31, which is rotatably mounted on the base plate 1. A movable wheel 32 is rotatably mounted on the support base 31, and a positioning plate 33 is fixedly mounted on the support base 31.

[0049] like Figure 1 , Figure 2 , Figure 9 , Figure 12 As shown, the base plate 1 has four corners, and each corner is equipped with a locking mechanism. The locking mechanism includes two locking components arranged at a 90-degree angle (e.g., Figure 9 Show) During normal use, the positioning plate 33 is in contact with the ground, and uneven particles can be set on the side of the positioning plate 33 in contact with the ground to adjust the friction between the positioning plate 33 and the ground and reduce the amplitude of the shaking of the base plate 1. When it is necessary to move the base plate 1 and the conveyor belt 4, the position can be switched to the contact of the moving wheel 32 with the ground. By pushing the base plate 1, the moving wheel 32 can be made to roll on the ground to complete the position switch.

[0050] A gear 30 is coaxially fixed on the support base 31. The gear 30 meshes with the rack 29. The rack 29 is slidably mounted on the base plate 1. The two racks 29 are connected by a drive assembly.

[0051] like Figure 9 , Figure 12 As shown, the two locking components arranged at a 90-degree angle have the same structure and each includes a rack 29. By driving the two racks 29 in sequence through the drive component, the state of the locking components can be switched. The mentioned states include two states: the moving wheel 32 is in contact with the ground and the positioning plate 33 is in contact with the ground.

[0052] The drive assembly includes a cylinder 24 fixedly mounted on a base plate 1. The extended end of the cylinder 24 is rotatably connected to one end of a drive rod 25, and the other end of the drive rod 25 is rotatably connected to a first push rod 26. The first push rod 26 is rotatably connected to a second push rod 27, and the second push rod 27 is slidably engaged with a straight groove on the base plate 1. The first push rod 26 is slidably engaged with a guide rod 28, and the guide rod 28 is fixedly mounted on a housing 23, which is also fixedly mounted on the base plate 1. One end of a connecting rod 36 is rotatably mounted on the first push rod 26, and the other end of the connecting rod 36 is slidably engaged with an optical shaft 37 fixedly mounted on the base plate 1. The optical shaft 37 is also slidably engaged with a connecting arm 39. A return spring 38 is sleeved around the outer ring of the optical shaft 37, and the connecting arm 39 is fixedly connected to a rack 29 away from the cylinder 24. The locking assembly also includes a "T"-shaped groove, which is composed of a vertical groove 34 and a horizontal groove 35 that are interconnected.

[0053] like Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, when adjusting the working state of the locking components, the two locking components arranged at a 90-degree angle at one corner of the base plate 1 need to be adjusted sequentially to ensure that the base plate 1 and the conveyor belt 4 remain stable during the adjustment process. Specifically, the cylinder 24 fixedly mounted on the base plate 1 is activated, causing the extended end of the cylinder 24 to extend and push the drive rod 25. At this time, the drive rod 25 will push the first push rod 26 and the second push rod 27 upward (towards...). Figure 9 (From the perspective of the viewpoint) the second push rod 27 slides along the straight groove on the base plate 1, the first push rod 26 slides along the guide rod 28, and the second push rod 27 is fixedly connected to the rack 29 near the cylinder 24. Therefore, the rack 29 will slide and drive the gear 30 meshing with the rack 29 to rotate. The gear 30 is coaxially connected to the support base 31, so the support base 31 and the positioning plate 33 on the support base 31 will rotate. The rotation direction is towards the "T" groove of the positioning plate 33. The positioning plate 33 can pass smoothly through the "T" groove. However, due to the presence of the support base 31, the support base 31 will be stuck above the "T" groove and cannot pass through. When the support base 31 is stuck above the "T" groove, the positioning plate 33 just rotates to contact the ground. At this time, the state switch of a locking component is completed.

[0054] After completing a locking component state switch, the extended end of cylinder 24 continues to extend. At this time, the first push rod 26 disengages from the guide rod 28 and rotates around the connection point with the second push rod 27 under the push of the drive rod 25. During the movement of the first push rod 26, it continuously pushes the connecting rod 36 to slide along the optical axis 37. When the first push rod 26 rotates around the second push rod 27, the connecting rod 36 contacts the connecting arm 39, thereby pushing the connecting arm 39 to drive the rack 29, which is away from cylinder 24, to slide along the base plate 1. During this process, the return spring 38 will generate elastic force due to deformation. The function of the return spring 38 is to assist the rack 29 connected to the guide rod 28 to return to its original position, as well as the connecting rod 36 to its original position. The moving rack 29 drives the gear 30 to rotate, causing the support base 31 to drive the moving wheel 32 and the positioning plate 33 to rotate, eventually causing the positioning plate 33 to contact the ground, while the moving wheel 32 is stuck above the "T" groove. This completes the state switch of one locking mechanism. The remaining three can be completed in sequence. In addition, the housing 23, which is fixedly installed on the base plate 1, mainly serves a protective function, and the housing 23 is located above the locking assembly.

[0055] It should be noted that if it is necessary for the wheel 32 to contact the ground, the cylinder 24 should be activated again and reset. This process involves the reversal of the extension of the cylinder 24, which will not be described further here. The above specific embodiments do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
