[0043] The core of the present utility model lies in disclosing an idler support to effectively improve the load-bearing capacity of the idler support.
[0044] Another core of the present utility model lies in disclosing a belt conveyor including the above idler support.
[0045] Hereinafter, the embodiments will be described with reference to the drawings. In addition, the embodiments shown below do not limit the content of the utility model described in the claims in any way. In addition, all the contents of the configurations shown in the following embodiments are not limited to those necessary for the solution of the utility model described in the claims. It should be noted that for the sake of description, only the parts related to the relevant utility model are shown in the drawings. Without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.
[0046] Combined with Figure 1 and Figure 10, the idler support disclosed by the utility model includes a support member 130, an idler bracket 110, a first connecting member 120, and a second connecting member 140. The idler bracket 110 includes a middle bracket and side brackets. The two side brackets are respectively connected to both ends of the middle bracket and form a notch structure with the middle bracket, with the opening facing away from the support member 130. The middle idler 100 is rotatably arranged on the middle bracket, and the side idler 101 is rotatably arranged on the side brackets. Under heavy load conditions, the stress of the idler support is mainly concentrated on the middle bracket and the side brackets. The first connecting member 120 is connected between the support member 130 and the middle bracket and can transfer the pressure generated by the material on the middle idler 100 and the middle bracket to the support member 130. The second connecting member 140 is connected between the support member 130 and the side brackets and can transfer the pressure generated by the material on the side idler 101 and the side brackets to the support member 130.
[0047] Compared with the prior art, the utility model effectively improves the load-bearing capacity of the idler support by respectively providing reliable support and force transmission for the middle bracket and the side brackets of the idler bracket 110 through the first connecting member 120 and the second connecting member 140, and also has the advantages of simple structure, convenient production and installation.
[0048] Specifically, in some embodiments, in combination with Figure 1 and Figure 9 , the first connecting member 120 can be a connecting plate. One side of the connecting plate is connected to the support member 130, and the other side is connected to the middle bracket.
[0049] In a further optimized solution, in order to ensure the support effect, the extension length of the above-mentioned connecting plate is greater than or equal to the extension length of the middle bracket, and both ends of the connecting plate extend to both ends of the middle bracket, that is, each part of the middle bracket along the extension direction can form a support with the support member 130 through the connecting plate, so as to increase the contact area between the connecting plate and the middle bracket and the support member 130, and more effectively transfer the acting force to ensure the load-bearing capacity.
[0050] In a further optimized structure, since the end part of the connecting plate is a stress concentration part, therefore, notches 121 are provided at both ends of the connecting plate. In combination with Figure 1 and Figure 2 , the setting of the notches 121 makes the idler bracket 110 and the connecting plate form a flexible whole, which can effectively reduce the stress concentration at the butt joint position of the idler bracket 110 and the connecting plate.
[0051] Specifically, under the same large-capacity conditions (the same heavy load situation), Figure 11 and Figure 12They are respectively the stress diagram and the deformation simulation result diagram when the extension length of the connecting plate is less than that of the middle bracket and the notch 121 is not opened. It can be seen that the stress is mainly concentrated at the connection position between the middle bracket and the connecting plate, with a maximum value of 396 MPa and a deformation of 5.06 mm. Figure 13 and Figure 14 They are respectively the stress diagram and the deformation simulation result diagram when the extension length of the connecting plate is equal to that of the middle bracket and the notch 121 is provided. It can be seen that the stress is mainly concentrated at the connection position between the second connecting member 140 and the supporting member 130, with a maximum value of 148 MPa and a deformation of 3.43 mm. Thus, increasing the extension length of the connecting plate (the connection area between the middle bracket and the supporting member 130) and opening the notch 121 can significantly reduce the concentrated stress, reduce the deformation, and improve the bearing capacity of the idler bracket.
[0052] In addition, in combination with Figure 3 , a first weight-reducing groove 122 can be opened at the middle position of the connecting plate to reduce the structural mass.
[0053] In a specific embodiment disclosed by the present utility model, in combination with Figure 4 , the first connecting member 120 can be a plurality of connecting rods arranged at intervals. The first end of the connecting rod is connected to the supporting member 130, and the second end is connected to the middle bracket. Compared with the structure where the first connecting member 120 is a connecting rod, the structure where the first connecting member 120 is a connecting plate is more convenient for welding production, but it has a heavier mass.
[0054] Among them, the cross-sectional sizes of the respective connecting rods can be the same or different. Exemplarily, the cross-section of the connecting rod located in the middle position can be appropriately increased to enhance its bearing capacity. In addition, the plurality of connecting rods can also be arranged in a non-uniform interval where the interval in the middle is small and the interval at both ends is large, so as to enhance the bearing capacity of the middle position of the middle bracket.
[0055] According to the specific structures of the supporting member 130 and the middle bracket, the two ends (or both sides of the connecting plate) of the connecting rod are adaptively arranged. Exemplarily, when the middle bracket is a tubular member, the end face of the first end of the connecting rod is a curved surface structure that fits the outer surface of the middle bracket (such as a curved surface structure with a semi-circular cross-section); when the supporting member 130 is a plate-like member, the end face of the second end of the connecting rod is a flat surface structure that corresponds to and is welded to the supporting member 130.
[0056] In combination with Figure 1 and Figure 6 , the first end of the second connecting member 140 is connected to the side bracket, and the second end is connected to the supporting member 130. The second connecting member 140 can specifically be a rod-shaped member or a plate-shaped member.
[0057] Since the two side brackets are respectively connected to both ends of the middle bracket and form an open structure with the opening facing away from the support member 130, that is, the angle between the side bracket and the middle bracket is greater than 90°. In order to achieve reliable support for the side bracket within a limited space, in combination with Figure 5 , when the second connecting member 140 is a rod-shaped member, the angle α between the second connecting member 140 and the support member 130 ( Figure 5 in, α 1 is less than 90°, α 2 is equal to 90°, α 3 is greater than 90°) is less than or equal to 90°. Correspondingly, the angle between the second connecting member 140 and the side bracket is less than or equal to 90°, so that the second connecting member 140 and the (connecting plate,) support member 130 and the side bracket jointly form a symmetric double triangular structure, increasing the stability of the idler bracket and improving the load-bearing capacity.
[0058] In one embodiment, in combination with Figure 6 , the second connecting member 140 is a plate-shaped member. Compared with the second connecting member 140 being a rod-shaped member, the plate-shaped member can effectively increase the contact area between the second connecting member 140 and the support member 130 and the side bracket, thereby improving the load-bearing capacity.
[0059] Furthermore, a second weight-reducing hole 141 for weight reduction is provided on the second connecting member 140. In combination with Figure 6 , the second weight-reducing hole 141 can be specifically arranged at the middle position of the second connecting member 140.
[0060] According to the specific structures of the support member 130 and the side idler, the end of the second connecting member 140 is correspondingly arranged to fit therewith. Exemplarily, when the side bracket is a tubular member, the end face of the first end of the second connecting member 140 is a curved surface structure that fits with the outer surface of the side bracket (such as a curved surface structure with a semi-circular cross-section); when the support member 130 is a plate-shaped member, the end face of the second end of the second connecting member 140 is a flat surface structure that fits and is welded with the support member 130.
[0061] The above-mentioned middle bracket and side bracket are usually of an integral structure. For example, the idler bracket 110 can be prepared by bending a round tube, or the middle bracket and the side bracket respectively correspond to a tube and are welded into an integral structure.
[0062] In combination with Figure 7 , when both the first connecting member 120 and the second connecting member 140 are plate-shaped members, they can also be of an integral structure.
[0063] In one embodiment, in combination with Figure 1 and Figure 8 , the second connecting member 140 is a rod-shaped member and can be one group or multiple groups supported between the side bracket and the support member 130.
[0064] The idler support 110 usually does not directly contact the ground, but is supported by the intermediate frame 200, and at the same time, the idler support 110 and the idlers have a certain working height. Correspondingly, a mounting plate 150 is provided on the support member 130, and connection holes for bolt connection with the intermediate frame 200 are formed on the mounting plate 150.
[0065] In a specific embodiment disclosed by the present utility model, in combination with Figure 1 , the height of the connecting plate is 60 mm to 160 mm; the notch 121 is a semi-circular notch 121, and its radius is 30 mm to 80 mm. The idler support 110 is prepared by bending a welded pipe with a diameter of Φ114 (the diameter of the idler support 110 can be adjusted according to the size of the idlers) into a trough shape, and an idler seat plate 102 is welded. The idlers are installed on the idler support through the idler seat plate 102. The connecting plate can be prepared by cutting a plate such as a steel plate, the support member 130 (cross beam) can be prepared by cutting a profile such as a channel steel according to the required length, and the second connecting member 140 (diagonal brace) can be prepared by cutting a profile such as an angle steel or a steel plate. The production and installation are both relatively convenient.
[0066] When the belt conveyor operates under heavy load, the gravity of the material acts on the idlers, and the idlers act on the idler support 110. The idler support 110 transmits the acting force to the support member 130 through the connecting plate and the second connecting member 140, reducing the stress concentration at the idler support 110 and the connecting plate. The idler support can support the idlers as a whole. The acting force of the support member 130 is transmitted to the ground through the intermediate seat 200.
[0067] In combination with Figure 10 , the belt conveyor disclosed by the present utility model includes middle idlers 100, side idlers 101 and the above-mentioned idler support. The middle idlers 100 are rotatably arranged on the middle support, and the side idlers 101 are rotatably arranged on the side support. Idler seat plates 102 can be respectively arranged on the middle support and the side support to support the middle idlers 100 and the side idlers 101, and allow the middle idlers 100 and the side idlers 101 to rotate freely. Due to the above-mentioned idler support, it also has the above-mentioned beneficial effects. Other structures refer to the prior art and will not be elaborated here.
[0068] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. The specific technical means in some embodiments can be partially or wholly combined into another embodiment on the premise that they are not explicitly excluded by another embodiment. Therefore, the present utility model will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
