[0002] After the production of conveyor belts is completed, they are usually stored and transported in conveyor belt rolls (conveyor belts are rolled up on the coil shaft). When in use, the conveyor belt rolls are unrolled and installed on the corresponding conveying equipment. In order to prevent the conveyor belt rolls from being squeezed and deformed due to being placed on the ground for a long time, a support frame is set corresponding to the conveyor belt roll.

DETAILED DESCRIPTION

[0036] like Figure 1-Figure 7 As shown, this embodiment provides a conveyor belt storage rack to provide a support function for a coil shaft with a conveyor belt. The conveyor belt storage rack includes a base frame 1 and at least two brackets. The base frame 1 has a slot inside. The base frame 1 is provided with a first socket 111 and a second socket 121 connected to the slot. The first socket 111 and the second socket 121 are both used for inserting a fork. The opening direction of the first socket 111 is different from the opening direction of the second socket 121. The bracket is connected to the base frame 1, and at least two brackets are arranged at intervals along the axial direction of the coil shaft. Each bracket is provided with a support seat 2, and two adjacent support seats 2 cooperate with each other to support the coil shaft with a conveyor belt.

[0037] The conveyor belt rack 100 of the embodiment of the present invention has multiple brackets connected to the base frame 1, so that the conveyor belt rack 100 is an integrated structure. When the coil is transported, the coil and the conveyor belt rack 100 can be transported together without removing the coil. Compared with the method of removing the coil from the conveyor belt rack 100 for transportation in the related art, the operation is simpler.

[0038] In addition, by providing the first socket 111 and the second socket 121, transportation can be carried out with the aid of a forklift. Specifically, the fork of the forklift can be inserted into the first socket 111 or the second socket 121. Moreover, since the opening directions of the first socket 111 and the second socket 121 are different, the forklift can be inserted into the slot from different directions to achieve lifting of the conveyor belt rack 100, which makes the operation more convenient.

[0039] As an example, Figure 1 As shown, the chassis 1 includes two transverse tubes 11 and two longitudinal tubes 12. The two transverse tubes 11 are parallel to each other and arranged at intervals, and the two longitudinal tubes 12 are parallel to each other and arranged at intervals. The transverse tubes 11 and the longitudinal tubes 12 are arranged alternately and welded to make the chassis 1 in a "well" shape.

[0040] Two first sockets 111 are formed at both ends of the transverse tube 11, and the distance between the two first sockets 111 at the same end of the transverse tube 11 matches the distance between the two forks of a forklift, so that the conveyor belt rack 100 and the coiled material can be transported by the forklift. Similarly, two second sockets 121 are formed at both ends of the longitudinal tube 12, and the distance between the two second sockets 121 at the same end of the longitudinal tube 12 also matches the distance between the two forks of the forklift.

[0041] The transverse tube 11 and the longitudinal tube 12 are both formed by welding steel plates. The internal cavity of the transverse tube 11 is the first slot, and the internal cavity of the longitudinal tube 12 is the second slot. The first slot and the second slot are interconnected at the positions where the transverse tube 11 and the longitudinal tube 12 are staggered, and the first slot and the second slot form the above-mentioned slot.

[0042] It is understandable that, according to parameters such as the weight and size of the coil, those skilled in the art may further reinforce the base frame 1 , for example, by adding a reinforcement structure between the two transverse tubes 11 and between the two longitudinal tubes 12 .

[0043] Of course, in other embodiments, the transverse tube 11 and the longitudinal tube 12 may also be made of rectangular tubes as long as they can meet the support strength requirements for the coiled material.

[0044] Optionally, there are two brackets, which are arranged at intervals at both ends of the transverse tube 11 along the length direction of the transverse tube 11 , and the lower side of the bracket is welded and fixed to the transverse tube 11 .

[0045] Thus, when the axial direction of the coil is consistent with the length direction of the transverse tube 11, the coil can be supported by the two support seats 2 so that the coil is lifted off the ground, thereby preventing the coil from being squeezed and deformed.

[0046] In some embodiments, the opening direction of the first socket 111 is perpendicular to the opening direction of the second socket 121. The chassis 1 has four insertion positions on its periphery, which is more conducive to inserting the forklift's fork into the first socket 111 or the second socket 121, further improving the convenience of operation.

[0047] like Figure 1 As shown, the transverse tube 11 and the longitudinal tube 12 are arranged perpendicular to each other.

[0048] In some embodiments, the bracket includes a vertical frame 3 and a positioning member. The vertical frame 3 is provided with a lifting slide adapted to the support seat 2. The support seat 2 is movably connected to the lifting slide in a sliding manner along the up and down directions. The support seat 2 has a first positioning portion, and the vertical frame 3 has a second positioning portion. Both the first positioning portion and the second positioning portion are positioned and matched with the positioning member to fix the relative positions of the support seat 2 and the vertical frame 3.

[0049] The support base 2 is movably connected to the vertical frame 3, so that the rolls of different specifications can be adapted, and when the rolls are placed on the conveyor belt storage rack 100, the conveyor belt storage rack 100 is more stable. For example, when the diameter of the roll is large, the support base 2 can be moved upward to leave enough space between the support base 2 and the bottom frame 1 so that the roll is separated from the bottom frame 1; when the diameter of the roll is small, the support base 2 can be moved downward to lower the center of gravity of the roll and improve the stability of the roll and the conveyor belt storage rack 100.

[0050] As an example, Figure 1 As shown, the two vertical frames 3 are respectively arranged at the two ends of the transverse tube 11 , and two connecting rods are further arranged between the two transverse tubes 11 . The two connecting rods are respectively arranged at the lower sides of the two vertical frames 3 .

[0051] The vertical frame 3 includes a vertical rod 31 and a diagonal brace 32, both of which are made of I-beams. The vertical rod 31 is vertically arranged, and there are two vertical rods 31. The two vertical rods 31 are arranged at intervals and a reinforcement block is welded between the two, which can reinforce the connection between the two vertical rods 31; there are two diagonal braces 32, and the two diagonal braces 32 are respectively arranged on the side away from each other of the two vertical rods 31, which can provide support for the vertical rod 31, and the two ends of the diagonal brace 32 are respectively welded and fixed to the vertical rod 31 and the cross tube 11.

[0052] like Figure 1 and Figure 2 As shown, the support seat 2 is slidably disposed between the two vertical rods 31 along the vertical direction, and the two vertical rods 31 are formed with a slide groove 311 on the side close to each other. The two sides of the support seat 2 are respectively inserted into the two slide grooves 311 and slidably cooperate with them. The two slide grooves 311 form a lifting slideway, and the height of the support seat 2 can be adjusted by sliding the support seat 2 up and down. Specifically, the slide groove 311 has a first groove wall 312 and a second groove wall 313 arranged at intervals along the length direction of the transverse tube 11, and the second groove wall 313 is closer to the coil than the first groove wall 312. The two side surfaces of the support seat 2 arranged at intervals along the length direction of the transverse tube 11 are respectively attached to the first groove wall 312 and the second groove wall 313, which can limit the sliding direction of the support seat 2.

[0053] Of course, in other embodiments, the two side surfaces of the support seat 2 arranged at intervals along the length direction of the transverse tube 11 may not fit the first groove wall 312 and the second groove wall 313 , as long as the support seat 2 can slide relative to the vertical frame 3 .

[0054] It can be understood that the coil includes a coil core and a material belt (such as a conveyor belt), the coil core is cylindrical, and the material belt is wound on the coil core. When the coil is supported on the conveyor belt storage rack 100, it is necessary to insert a support shaft into the coil core of the coil, and the support shaft can be a hollow steel pipe, a solid round rod, etc., and then the two ends of the support shaft are respectively mounted on two support seats 2, so that the coil can be supported.

[0055] Alternatively, if Figure 1 and Figure 2 As shown, the upper side of the support seat 2 has a support groove 21, and the support groove 21 is semicircular.

[0056] Thus, both ends of the support shaft for inserting the winding core can be placed in two supporting grooves 21 respectively, and the groove walls of the supporting grooves 21 can limit the support shaft and allow the support shaft to rotate relative to the supporting grooves 21, thereby achieving stable support for the coil.

[0057] Alternatively, if Figure 2 and Figure 3 As shown, a semicircular support member 22 is welded on the side of the two support seats 2 facing away from each other. The support member 22 also forms a semicircular support groove 21 , and the support groove 21 of the support member 22 is coaxially arranged with the support groove 21 of the support seat 2 .

[0058] Thereby, the contact area with the support shaft can be increased, further increasing the stability of the coil support.

[0059] In some embodiments, Figure 2 As shown, the first positioning portion is the first positioning hole 23 , the second positioning portion is the second positioning hole 314 , the positioning member is the positioning rod 4 , and the positioning rod 4 passes through the first positioning hole 23 and the second positioning hole 314 .

[0060] The support base 2 can be fixed on the vertical frame 3 by passing the positioning rod 4 through the first positioning hole 23 and the second positioning hole 314 , and the operation is relatively simple.

[0061] As an example, Figure 2 As shown, the first positioning hole 23 penetrates the support seat 2 along the length direction of the transverse tube 11, and the second positioning hole 314 penetrates the vertical frame 3 along the length direction of the transverse tube 11. Specifically, the second positioning hole 314 penetrates the first groove wall 312 and the second groove wall 313 of the slide groove 311; the positioning rod 4 is inserted into the first positioning hole 23 and the second positioning hole 314 along the end of the transverse tube 11 toward its center, so as to fix the support seat 2.

[0062] In some embodiments, there are multiple second positioning holes 314, and the multiple second positioning holes 314 are arranged at intervals along the moving direction of the support base 2 relative to the vertical frame 3. The first positioning hole 23 can be aligned with any second positioning hole 314 so that the positioning rod 4 passes through the first positioning hole 23 and the second positioning hole 314.

[0063] By providing a plurality of second positioning holes 314 , the support base 2 can be fixed at different heights to accommodate coils of different specifications.

[0064] As an example, Figure 1 As shown, two groups of first positioning holes 23 are provided, each group has two holes, and the two first positioning holes 23 in the same group are arranged at intervals in the vertical direction. The two groups of first positioning holes 23 are arranged at intervals along the length direction of the longitudinal tube 12, and are respectively arranged on both sides of the support groove 21, that is, four first positioning holes 23 are provided on each support seat 2.

[0065] There are also two groups of second positioning holes 314, which are respectively arranged on two vertical rods 31. There are multiple second positioning holes 314 in each group. The multiple second positioning holes 314 in the same group are evenly arranged along the vertical direction, and the spacing between two adjacent second positioning holes 314 in the same group is equal to the spacing between two adjacent first positioning holes 23 in the same group.

[0066] Correspondingly, each support seat 2 is provided with four positioning rods 4. The support seat 2 is adjusted to a suitable height, the four first positioning holes 23 on the support seat 2 are aligned one by one with the four second positioning holes 314, and the four positioning rods 4 are inserted respectively, so that the support seat 2 can be stably fixed on the vertical frame 3.

[0067] In some embodiments, the conveyor belt rack 100 further includes a lifting mechanism, which is used to drive two adjacent support seats 2 to rise synchronously to achieve the lifting function of the coil. Specifically, the lifting mechanism includes two lifting components 5 and a transmission component 6, the two lifting components 5 correspond to the two support seats 2 one by one, and the two lifting components 5 are connected to the transmission component 6. The transmission component 6 is used to achieve the synchronous movement of the two lifting components 5, so that the two ends of the coil are balanced and the stability of the coil rising is improved.

[0068] It is understandable that the weight of the coil is relatively large. When the coil is supported on the support seat 2, the coil can be lifted and then the two ends of the support shaft inserted in the coil can be placed in the support groove 21. However, when the workplace does not have the lifting capacity, it is difficult to lift the coil, which makes it difficult to support the coil on the conveyor belt rack 100, which is more troublesome.

[0069] By setting up the lifting component 5, the coil can be rolled onto the base frame 1 by means of a wedge or the like, and then the support seat 2 is moved downward so that the center of the support groove 21 is at the same height as the center of the coil, the support shaft of the coil passes through the winding core and is erected in the support groove 21, and then the support seat 2 is lifted upward to a suitable height by the lifting component 5, and then the support seat 2 is fixed by the positioning piece, which is more conducive to supporting the coil on the conveyor belt storage rack 100.

[0070] In some embodiments, the lifting assembly 5 includes two pulley assemblies and a synchronization assembly, the two pulley assemblies are respectively arranged on both sides of the support base 2, and the two pulley assemblies are connected by the synchronization assembly. Figure 4 As shown, the pulley assembly includes a first pulley 51, a second pulley 52, a rope 53 and a drum 54; the first pulley 51 is rotatably connected to the support seat 2, the second pulley 52 is rotatably connected to the vertical frame 3, the second pulley 52 is higher than the first pulley 51, the first pulley 51 is higher than the drum 54, the rope 53 is sequentially wound around the lower side of the first pulley 51 and the upper side of the second pulley 52, the rope 53 has a first end 531 and a second end 532, the first end 531 is connected to the vertical frame 3, and the second end 532 is wound around the drum 54, so as to drive the support seat 2 to rise when the drum 54 reels the rope 53.

[0071] Through the above arrangement, when the operator rotates the drum 54 and reels the rope 53, the rope 53 on both sides of the first pulley 51 is in a taut state, and the rope 53 exerts an upward force on the first pulley 51, thereby driving the support seat 2 to rise; when the operator rotates the drum 54 to unwind the rope 53, the rope 53 on both sides of the first pulley 51 is in a slack state, and the upward lifting force of the rope 53 on the first pulley 51 is reduced, and the support seat 2 can be lowered under the action of its gravity.

[0072] As an example, Figure 4 As shown, each vertical frame 3 corresponds to two pulley assemblies, that is, each vertical frame 3 corresponds to two first pulleys 51, and the two first pulleys 51 are arranged at intervals along the length direction of the longitudinal tube 12 and are respectively arranged on both sides of the support groove 21. Through the two first pulleys 51, a more uniform lifting force can be applied to the support seat 2, so that the support seat 2 can rise stably.

[0073] The vertical frame 3 includes a mounting frame 33 located at the top, and the second pulley 52 is rotatably connected to the mounting frame 33; a mounting rod 34 is fixedly connected to the mounting frame 33, and the first end 531 of the rope 53 is fixedly connected to the mounting rod 34. The two second pulleys 52 arranged on the same vertical frame 3 are located on the outside of the two mounting rods 34.

[0074] The drum 54 is arranged at the lower side of the diagonal support 32, and a reel 55 is fixedly provided on the drum 54, and the reel 55 is rotatably connected to the diagonal support 32. The rope 53 passes through the lower side of the first pulley 51 and the upper side of the second pulley 52 from the first end 531 to the second end 532, and then is wound on the drum 54 from the side of the drum 54 close to the vertical frame 3, and the second end 532 of the rope 53 is fixed on the wall of the drum 54. The drum 54 can be controlled to rotate by rotating the reel 55, thereby realizing the winding and unwinding of the rope 53.

[0075] like Figure 4 and Figure 5 As shown, a transmission assembly 6 is arranged between the two corresponding pulley assemblies on the two vertical frames 3. In other words, the two corresponding pulley assemblies along the length direction of the horizontal tube 11 are connected to each other through the transmission assembly 6. Under the action of the transmission assembly 6, the two corresponding reels 54 along the length direction of the horizontal tube 11 can rotate synchronously, thereby driving the two support seats 2 to rise at the same time, so that the coiled material remains balanced.

[0076] The transmission assembly 6 includes a transmission shaft 61 and two transmission mechanisms. The transmission shaft 61 passes through the base frame 1 and is rotatably connected to the base frame 1. The two transmission mechanisms are respectively arranged at both ends of the transmission shaft 61. The ends of the transmission shaft 61 are connected to the reels 55 through the transmission mechanisms, which can drive the transmission shaft 61 and the two reels 55 to rotate synchronously, thereby driving the two reels 54 to rotate synchronously.

[0077] The transmission mechanism includes a transmission belt 62 and two pulleys 63. The two pulleys 63 are fixedly mounted on the reel 55 and the transmission shaft 61 respectively. The transmission belt 62 is wound around the two pulleys 63 so that the two pulleys 63 rotate, thereby driving the reel 55 and the transmission shaft 61 to rotate synchronously.

[0078] It is understandable that those skilled in the art can reasonably design the relative position of the transmission assembly 6 and the slot to reduce the probability of the fork of the forklift colliding with the transmission assembly 6 when the fork is inserted into the slot.

[0079] In some embodiments, Figure 5 As shown, the conveyor belt rack 100 also includes a non-return assembly 7, which includes a ratchet 71 and a pawl 72. The ratchet 71 is connected to the drum 54 and rotates synchronously. The ratchet 71 has a locking groove. The pawl 72 is rotatably connected to the vertical frame 3. The pawl 72 has a locking portion to prevent the drum 54 from unwinding the rope 53 when the locking portion cooperates with the locking groove.

[0080] Due to the heavy weight of the coiled material, if an accident occurs accidentally while the operator is controlling the reel 54 to lift the coiled material, the coiled material will fall rapidly under the action of its gravity, posing a great safety hazard. Through the above arrangement, the operator can lift the support seat 2 while using the reel 54 to reel the rope 53. At this time, the ratchet 71 rotates forward with the reel 54, and the pawl 72 has no restrictive effect on the ratchet 71. When the coiled material falls under the action of its gravity, it will drive the reel 54 to unwind the rope 53, causing the ratchet 71 to rotate in the opposite direction with the reel 54. At this time, the pawl 72 cooperates with the ratchet 71 to prevent the ratchet 71 from rotating in the opposite direction, thereby preventing the reel 54 from unwinding the rope 53, thereby preventing the coiled material from falling and reducing safety hazards.

[0081] As an example, Figure 5 and Figure 6 As shown, the ratchet 71 is mounted on the reel 55 and rotates synchronously with the reel 55; the pulley 63 and the ratchet 71 are respectively arranged on both sides of the reel 54, thereby making the arrangement of the pulley 63, the reel 54 and the ratchet 71 more reasonable.

[0082] The locking groove has a first side wall 711 and a second side wall 712 , and the locking portion has a first stop surface 721 and a second stop surface 722 . When the locking portion cooperates with the locking groove, the first stop surface 721 stops at the first side wall 711 , and the second stop surface 722 fits the second side wall 712 .

[0083] Therefore, when the locking portion cooperates with the locking groove, the ratchet 71 rotates forward, and the second side wall 712 can push the pawl 72 away, so that the locking portion disengages from the locking groove, and the ratchet 71 can rotate forward; when the ratchet 71 rotates reversely, the first side wall 711 is tightly in contact with the first stop surface 721, and the locking portion cannot disengage from the locking groove, thereby preventing the ratchet 71 from rotating reversely.

[0084] Optionally, there are multiple locking grooves, which are evenly arranged along the circumference of the ratchet 71 , and the locking portion of the pawl 72 cooperates with any one of the locking grooves to prevent the ratchet 71 from rotating in the opposite direction.

[0085] In some embodiments, the anti-return assembly 7 further includes an elastic member 73 , and the elastic member 73 is used to apply elastic force to the pawl 72 so that the pawl 72 has a tendency to rotate toward the ratchet wheel 71 .

[0086] Under the action of the elastic member 73 , the locking portion of the pawl 72 can be matched with any locking groove of the ratchet 71 to prevent the coil from falling rapidly.

[0087] like Figure 5 As shown, a rotating shaft 723 is fixedly provided on the ratchet 72 , and the rotating shaft 723 is rotatably connected to the diagonal support 32 .

[0088] Optionally, the elastic member 73 is a torsion spring, which is sleeved on the rotating shaft 723 , with one end of the torsion spring fixedly connected to the rotating shaft 723 and the other end of the torsion spring fixedly connected to the diagonal support 32 .

[0089] Thus, the torsion spring can apply torque to the rotating shaft 723, so that the pawl 72 always has a tendency to rotate in the direction of the ratchet 71. In other words, the locking portion always has a tendency to cooperate with the locking groove, so that the locking portion of the pawl 72 is inserted into the locking groove of the ratchet 71.

[0090] Optionally, an operating rod 724 is fixedly connected to the pawl 72 , and the operating rod 724 passes through the side wall of the diagonal support 32 and extends to the outside of the diagonal support 32 . A clearance groove for the operating rod 724 to pass through is opened on the side wall of the diagonal support 32 .

[0091] The pawl 72 can be controlled by the operating rod 724 to rotate in a direction away from the ratchet 71 and then disengage from the ratchet 71 so as to achieve the lowering of the support base 2.

[0092] In some embodiments, Figure 7 As shown, the positioning rod 4 is provided with a limiting section 412, the hole wall of the first positioning hole 23 has a first limiting groove 231, the limiting section 412 is limitedly matched with the first limiting groove 231, the first pulley 51 has a third positioning hole 511, the hole wall of the third positioning hole 511 has a second limiting groove 5111, the limiting section 412 passes through the first positioning hole 23 and the third positioning hole 511, and the first limiting groove 231 and the second limiting groove 5111 are both limitedly matched with the limiting section 412.

[0093] Through the above arrangement, when the positioning rod 4 fixes the support seat 2, it can be inserted into the first positioning hole 23, the second positioning hole 314 and the third positioning hole 511 at the same time, and the limiting section 412 can simultaneously cooperate with the first limiting groove 231 and the second limiting groove 5111 to prevent the first pulley 51 from supporting the seat 2 from rotating, thereby further improving the stability of the coiled material.

[0094] like Figure 7 As shown, the limiting section 412 includes a plurality of limiting protrusions 4121 uniformly arranged along its circumference, and the projection of the limiting protrusion 4121 on the cross section of the limiting section 412 is semicircular; the shape of the first limiting groove 231 matches the shape of the limiting protrusion 4121, and the number of the first limiting grooves 231 is multiple, and the plurality of first limiting grooves 231 are uniformly arranged along the circumference of the first positioning hole 23, and the first limiting grooves 231 correspond one-to-one to the limiting protrusion 4121. When the limiting section 412 is inserted into the first positioning hole 23, it can prevent the positioning rod 4 and the support seat 2 from rotating relative to each other.

[0095] There are multiple second limiting grooves 5111, and the multiple second limiting grooves 5111 are evenly arranged along the circumference of the third positioning hole 511. The second limiting grooves 5111 correspond to the limiting protrusions 4121 one by one. When the limiting segment 412 is inserted into the third positioning hole 511, it can prevent the positioning rod 4 and the first pulley 51 from rotating relative to each other, thereby preventing the support seat 2 and the first pulley 51 from rotating relative to each other, so that the support seat 2 and the first pulley 51 remain relatively stationary.

[0096] The support seat 2 is provided with a receiving groove 24 , and the first pulley 51 is rotatably disposed in the receiving groove 24 . The first pulley 51 and the first positioning hole 23 are coaxially arranged.

[0097] As an example, Figure 7 As shown, the positioning rod 4 corresponding to the two first positioning holes 23 on the upper side of the support seat 2 is a first positioning rod 41, and the first positioning rod 41 includes a first rod segment 411, a limiting segment 412 and a second rod segment 413 arranged in sequence, wherein the first rod segment 411 cooperates with the second positioning hole 314 on the first groove wall 312, and the second rod segment 413 cooperates with the second positioning hole 314 on the second groove wall 313, and the first positioning hole 23 and the third positioning hole 511 both cooperate with the limiting segment 412, and the projection of the first rod segment 411 on the cross section of the first positioning rod 41 can completely cover the projection of the limiting segment 412 on the cross section of the first positioning rod 41, and the projection of the limiting segment 412 on the cross section of the first positioning rod 41 can completely cover the projection of the second rod segment 413 on the cross section of the first positioning rod 41.

[0098] Correspondingly, the second positioning hole 314 on the second groove wall 313 is smaller than the second positioning hole 314 on the first groove wall 312 , so that the first positioning rod 41 can fit with the hole wall of the second positioning hole 314 to achieve a better positioning effect for the support seat 2 .

[0099] Thus, the first positioning rod 41 can pass through the second positioning hole 314 , the first positioning hole 23 and the third positioning hole 511 from the side of the two vertical frames 3 that are relatively far away from each other.

[0100] like Figure 7 As shown, the positioning rod 4 corresponding to the two first positioning holes 23 on the lower side of the support seat 2 is the second positioning rod 42, and the second positioning rod 42 includes a first part 421 and a second part 422. The first positioning hole 23 and the second positioning hole 314 on the first groove wall 312 are both matched with the first part 421, and the second positioning hole 314 on the second groove wall 313 is matched with the second part 422; thus, the second positioning rod 42 can pass through the second positioning hole 314 and the first positioning hole 23 from the side relatively far away from the two vertical frames 3.

[0101] Of course, in other embodiments, the apertures of the first positioning hole 23 and the second positioning hole 314 may be set to be equal, and accordingly, the diameter of the rod portion of the positioning rod 4 is equal to the apertures of the first positioning hole 23 and the second positioning hole 314 .

[0102] This embodiment also provides a finite element analysis method for the above-mentioned conveyor belt rack to verify whether the conveyor belt rack meets the corresponding standards. The finite element analysis method includes:

[0103] Step A, material setting, select the material of the conveyor belt rack, and make corresponding settings in the material library of the finite element analysis software (ANSYS software). Here, the material of the conveyor belt rack is set to structural steel.

[0104] Step B, model creation, creating a three-dimensional model of the conveyor belt rack, and importing the three-dimensional model into the finite element analysis software. Specifically, the three-dimensional model of the conveyor belt rack is created using the three-dimensional software Solidworks, and then converted into STP format and imported into the ANSYS software for finite element analysis.

[0105] Step C, mesh division, define the material of the conveyor belt rack parts, and use tetrahedral mesh to divide the three-dimensional model of the conveyor belt rack to obtain the mesh model of the conveyor belt rack. In the ANSYS software, select the material definition as structural steel, and obtain the mesh model through tetrahedral mesh division.

[0106] Step D, boundary condition setting, includes constraint setting and load application.

[0107] Step E, solving and calculating, in the grid model, according to the working state of the conveyor belt rack, the base frame 1 of the conveyor belt rack is fixed, and the support seat 2 of the conveyor belt rack is loaded with a longitudinal load of 30 tons, and the first load loading is performed; the base frame 1 of the conveyor belt rack is fixed, and the support seat 2 of the conveyor belt rack is loaded with a longitudinal load of 30 tons, and a lateral pulling force of 300N is applied to the support seat 2, and the second load loading is performed; according to the data of the first load loading and the second load loading, the displacement cloud map is solved by using the finite element analysis software.

[0108] Step F, result analysis, analyze whether the conveyor belt rack meets the corresponding standards according to the displacement cloud map. Specifically, the force and displacement of the conveyor belt rack are analyzed through the displacement cloud map to obtain the maximum displacement and stress. In this embodiment, the conveyor belt rack only bears 30 tons of gravity and 30 tons of gravity and 300N lateral tension. The deformation and stress of the two do not change much, and are almost close, meeting the corresponding standards.
