Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a universal intermediate frame for belt conveyors. Background Technology

[0002] Existing belt conveyor intermediate frames, such as the DTII(A) series, have a standard length of 6000mm and are available in light-duty and heavy-duty versions.

[0003] In terms of finished product structure: the lightweight version is made with symmetrical panels on both sides. The heavy-duty version has crossbeams connecting the left and right sides, making them a single unit.

[0004] In terms of connection method: there are mounting holes for connecting plates at both ends of the side of the intermediate frame; there are no connecting holes between the intermediate frame and the support legs; there are 5 sets of mounting holes for upper rollers on the top surface of the intermediate frame, with a spacing of 1200mm, and 2 sets of mounting holes for lower rollers on the bottom surface, with a spacing of 3000mm.

[0005] The standard length of the DTII series intermediate frame is 6000mm.

[0006] In terms of finished product structure: it is made symmetrically on the left and right sides.

[0007] In terms of connection method: there are mounting holes for connecting plates at both ends of the side of the intermediate frame; there are connection holes between the intermediate frame and the type I and type II support legs at specific positions; there are 5 sets of upper roller mounting holes on the top surface of the intermediate frame with a spacing of 1200mm, and 2 sets of lower roller mounting holes on the bottom surface with a spacing of 3000mm.

[0008] The standard length of the TD75 series intermediate frame is 6000mm.

[0009] In terms of finished product structure: it is made symmetrically on the left and right sides.

[0010] In terms of connection method: there are mounting holes for connecting plates at both ends of the side of the intermediate frame; there are no connecting holes between the intermediate frame and the support legs; there are 5 sets of mounting holes for upper rollers on the top surface of the intermediate frame, with a spacing of 1200mm, and 2 sets of mounting holes for lower rollers on the bottom surface, with a spacing of 3000mm.

[0011] The standard length of the intermediate frame for the 96 series of coal is 6000mm.

[0012] In terms of finished product structure: it is made symmetrically on the left and right sides, with horizontal connecting braces and diagonal braces connected by bolts.

[0013] In terms of connection method: there are type II support leg connection holes on the side end of the intermediate frame and type I support leg connection holes in the middle, with 1000mm spacing for mounting holes; there are 5 sets of upper roller mounting holes on the top surface of the intermediate frame with a spacing of 1200mm, and 2 sets of lower roller mounting holes on the bottom surface with a spacing of 3000mm.

[0014] The structure of the aforementioned series, except for the 96 coal series which has pre-drilled mounting holes spaced 1000mm apart on the side of the intermediate frame, does not have pre-drilled mounting holes in other series. Furthermore, the 1000mm spacing of the mounting holes in the 96 coal series is inconsistent with the installation dimensions of conventional components such as guide chutes, guardrail supports, protective device supports, pressure rollers, crossing ladders, iron separator supports, and lower pressure roller sets. If additional equipment needs to be installed, the intermediate frame must be non-standardly designed on-site, or welded on-site. Non-standard design prevents mass production, and on-site welding restricts flexible assembly and disassembly, both of which have certain drawbacks.

[0015] In terms of production and manufacturing: the factory produces a large volume of non-standard products, resulting in low efficiency, high costs, and the need for categorized storage and separate packaging, which takes up a lot of space.

[0016] Regarding shipping: Goods are separated into left and right sides and paired up. Non-standard parts need to be bundled and paired up separately, and their labels and packaging need to be distinguished. This consumes a lot of labor and takes up a lot of space.

[0017] On-site installation: The task of checking and sorting non-standard parts is large and prone to errors. When installing additional components such as guide troughs, guardrail brackets, protective device brackets, pressure rollers, crossing ladders, iron remover brackets, and lower pressure roller groups, welding is required, which poses a high risk of environmental pollution. Summary of the Invention

[0018] The purpose of this invention is to address the shortcomings of existing technologies and provide a universal intermediate frame for belt conveyors.

[0019] To achieve the above objectives, this utility model is implemented according to the following technical solution: A universal intermediate frame for belt conveyors includes two symmetrical U-shaped steel frames. Each U-shaped steel frame has two mounting plate connection holes symmetrically arranged from top to bottom at both ends of its sidewalls for connecting mounting plates. The sidewalls of the U-shaped steel frames also have several support leg mounting holes arranged from top to bottom and several inclined support connection holes arranged in two directions for mounting inclined supports. The upper sidewall of the U-shaped steel frame has several upper idler frame mounting holes arranged in two horizontal directions for mounting upper idler frames, and the lower sidewall of the U-shaped steel frame has several lower idler frame mounting holes arranged in two horizontal directions for mounting lower idler frames.

[0020] Furthermore, the mounting holes of the upper roller frame are symmetrically distributed on both sides of the center of the upper side wall of the U-shaped steel frame, and the mounting holes of the lower roller frame are symmetrically distributed on both sides of the center of the lower side wall of the U-shaped steel frame.

[0021] Compared with the prior art, the present invention has the following beneficial effects: 1. The standard length of the universal intermediate frame of this utility model is available in two types: 6000mm and 3000mm. The centerline of the intermediate frame is symmetrical along its length direction. The left and right pieces are completely identical and interchangeable, without needing to distinguish between the left and right side pieces. The 6000mm intermediate frame is used for horizontal and inclined arrangements, while the 3000mm intermediate frame is used for convex and concave arc sections. The side ends of the intermediate frame have mounting holes for connecting plates, and the middle has connecting holes for Type I legs and Type II legs with different diagonal brace lengths, with mounting holes reserved at 1000mm intervals. The top surface of the intermediate frame has 11 sets of upper roller frame mounting holes spaced 600mm apart, and the bottom surface has 4 sets of lower roller frame mounting holes spaced 1500mm apart. The side has pre-drilled mounting holes spaced 1000mm apart for connection to components such as guide chutes, guardrail supports, and iron separator supports. The top surface has 11 mounting holes; besides the 5 upper idler roller frames, the remaining holes are used for connecting protective device supports, pressure rollers, crossing ladders, and other components. The bottom surface has 4 mounting holes; besides the 2 lower idler roller frames, the remaining holes are used for connecting lower pressure roller frames, empty section cleaners, and other components. There is no need to distinguish between the left and right intermediate frames; they are completely interchangeable for installation.

[0022] 2. This utility model's universal intermediate rack is manufactured in a standardized factory, resulting in high efficiency, low cost, no need for categorization or packaging, and minimal space occupation. The intermediate rack does not require further processing into an arc shape, reducing processing costs. Production efficiency is high.

[0023] 3. The universal intermediate frame of this utility model does not distinguish between left and right, and can be bundled and packaged as a whole, which consumes less labor, occupies less space, and has low transportation costs.

[0024] 4. This utility model's universal intermediate frame has no left or right distinction, allowing for immediate use and improving installation efficiency while reducing labor intensity. It also minimizes on-site welding, making it environmentally friendly and reducing pollution. Attached Figure Description
