Description

Technical Field

[0001] This utility model belongs to the technical field of belt conveyors, and specifically relates to a belt conveyor truss. Background Technology

[0002] The truss of a belt conveyor serves as the supporting structure of the belt conveyor system, affecting the equipment's operational stability and maintenance costs. Current mainstream truss structures suffer from the following drawbacks:

[0003] Existing trusses mostly adopt flat plate splicing or channel steel welded frames, with a single structural form and reliance on intensive welding processes. Moreover, dust and loose materials generated during material transportation overflow through structural gaps, forcing frequent manual cleaning. The non-modular design results in poor component versatility, requiring customized trusses for different specifications of conveyors, extending the production cycle and increasing the difficulty of spare parts management.

[0004] Therefore, there is a need for a belt conveyor truss that is lower in cost and more environmentally friendly. Utility Model Content

[0005] The purpose of this utility model is to provide a belt conveyor truss with stable structure, strong overall sealing, less steel material, and reduced welding process, which greatly saves material and processing costs without reducing the performance.

The bottom of the bent plates is fixedly connected by angle steel, and the top of the angle steel is provided with a receiving plate. The two ends of the receiving plate are connected to the bent plates.

[0007] Preferably, the bending plate is a bent structural component, and the bending plate is connected to the receiving plate to form a U-shaped structure.

[0008] Preferably, multiple angle steel bending plates are spaced apart along the length direction, and the top of the angle steel is welded and fixed to the bending plate.

[0009] Preferably, the stiffening plates are staggered on the inner side of the bent plate, and their edges are fully welded to the bent surface of the bent plate.

[0010] Preferably, the inspection and observation port is an opening structure located on the side of the bent plate, with the axis of the observation port at an angle of 30-60° to the horizontal plane.

[0011] Preferably, the receiving plate is a steel plate continuously laid on top of the angle steel, and the two sides of the receiving plate are bent upward to form a retaining edge.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This utility model features a stable truss structure with strong overall sealing, uses less steel, and reduces welding processes, thus greatly saving material and processing costs without compromising performance. Attached Figure Description

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, as Figure 1-2 As shown, a belt conveyor truss includes a bent plate 1, angle steel 2, stiffening plate 3, inspection and observation port 4, and receiving plate 5 arranged opposite to each other on both sides. The stiffening plate 3 is welded to the inner side of the bent plate 1, and the stiffening plate 3 reinforces the bent plate 1. The stiffening plate 3 is specifically arranged in high stress areas to avoid the material waste of traditional full-coverage stiffening plate 3. The inspection and observation port 4 is welded at the opening on the side of the bent plate 1. The inspection and observation port 4 provides a visual inspection channel for the belt and idlers, and the condition of the idlers can be checked without disassembling the structure, reducing downtime.

[0021] The bottom of the bent plate 1 is fixedly connected by angle steel 2. The angle steel 2 is welded to the bottom of the bent plate 1 at intervals along the length of the truss, achieving lateral positioning and load transfer. Compared with the channel steel beam, the angle steel 2 is significantly lighter while meeting strength requirements. A receiving plate 5 is set on the top of the angle steel 2, and the two ends of the receiving plate 5 are connected to the bent plate 1. The bent plate 1, as the main support body on both sides of the truss, is formed into a three-dimensional skeleton through bending, and together with the receiving plate 5, it forms a U-shaped sealed cavity to seal the belt running area. The one-piece bending and forming replaces the traditional splicing of multiple flat plates, reducing the amount of steel used and eliminating the longitudinal welds of the traditional frame, thus reducing the risk of welding deformation. The receiving plate 5 is continuously laid on the upper flange of the angle steel 2. The U-shaped groove and the side guard achieve full-section sealing, reducing dust emission, directly bearing the impact of falling materials, protecting the angle steel 2 from wear, and extending the service life of the main structure.

[0022] The specific design of the aforementioned key components will be discussed in detail below:

[0023] The bending plate 1 is a structural component formed by bending. The bending plate 1 is connected to the receiving plate 5 to form a U-shaped structure. The bending ridges form natural reinforcing ribs, which have a deformation resistance that surpasses that of traditional flat plate splicing. The bending of a single steel plate replaces the assembly of multiple parts, reducing steel consumption and splicing welds. Together with the receiving plate 5, it forms a closed U-shaped channel to prevent lateral leakage of materials.

[0024] Multiple angle steels 2 and bent plates 1 are spaced apart along their length, and the tops of the angle steels 2 are welded and fixed to the bent plates 1. Compared with full-coverage beams, angle steels 2 reduce weight and lower the power requirements of the conveyor drive. A spacing of 1.5m is recommended to enable rapid positioning and welding, improving installation efficiency. The truss length can be adjusted by increasing or decreasing the number of angle steels 2, and it is applicable to 6m / 9m / 12m series.

[0025] The stiffening plates 3 are staggered on the inner side of the bent plate 1, and their edges are fully welded to the bending surface of the bent plate 1. They are staggered along the stress flow lines, with 30% of the stiffening plates 3 covering 90% of the high-stress area. The full weld eliminates the source of bolt hole cracks, and single-sided continuous welding replaces double-sided intermittent welding.

[0026] The inspection and observation port 4 is an opening structure located on the side of the bending plate 1, with the axis of the observation port at an angle of 30-60° to the horizontal plane. The 45° angle allows for unobstructed observation of the wear status of the idler roller, and the inclined opening prevents dust from accumulating, reducing the frequency of maintenance.

[0027] The receiving plate 5 is a continuous steel plate laid on top of the angle steel 2. The two sides of the receiving plate 5 are bent upward to form retaining edges. The double-bent retaining edges form a guide channel. The receiving plate 5 is a 3mm thick manganese steel plate that is continuously laid, which reduces maintenance costs compared to the segmented receiving box and also serves as a maintenance platform step, eliminating the need for an additional walkway structure.

[0028] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
