Abstract
Description
Technical Field
[0001] This utility model relates to a roller frame, specifically a deep groove type roller frame. Background Technology
[0002] See Figure 1 Existing deep-groove idler frames typically include a horizontal mounting plate 100, on which four sets of mounting brackets 110 are provided. Each set of brackets 110 consists of two supports, with an idler roller 120 positioned between the two supports. The idler roller 120 can rotate between the supports. The aforementioned idler frame has the following problems: the four idlers are arranged symmetrically in a double V-shape, leaving the heavily loaded middle section of the conveyor belt unsupported, resulting in unreasonable stress on the belt, which easily leads to belt cracking, damage, and reduced belt lifespan. Summary of the Invention
[0003] In order to solve the above problems, this utility model provides a deep groove type idler roller frame.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A deep groove type idler frame includes a horizontal mounting plate, on which an installation support frame is provided, and a first idler, a second idler, a third idler, a fourth idler and a fifth idler are sequentially arranged on the installation support frame.
[0005] In a preferred embodiment of this utility model, the mounting support frame includes a first support frame, a second support frame, a third support frame, a fourth support frame, and a fifth support frame, which are symmetrically welded to a horizontal mounting plate from the outside to the inside along the longitudinal center line of the roller frame. The first roller is sleeved on the first support frame and the third support frame, the second roller is sleeved on the second support frame and the fourth support frame, the third roller is sleeved on the fifth support frame, the fourth roller is sleeved on the second support frame and the fourth support frame, and the fifth roller is sleeved on the first support frame and the third support frame.
[0006] In a preferred embodiment of this utility model, the included angle between the first idler roller and the second idler roller after they are sleeved together is 15°~30°.
[0007] In a preferred embodiment of this utility model, the included angle between the second idler roller and the third idler roller after they are sleeved together is 30°~45°.
[0008] In a preferred embodiment of this utility model, the included angle between the third and fourth idlers after they are sleeved together is 30° to 45°.
[0009] In a preferred embodiment of this utility model, the included angle between the fourth and fifth idlers after they are sleeved together is 15° to 30°.
[0010] In a preferred embodiment of this utility model, the first idler roller and the fifth idler roller are symmetrically distributed on the left and right sides of the third idler roller.
[0011] In a preferred embodiment of this utility model, the second and fourth idlers are symmetrically distributed on the left and right sides of the third idler.
[0012] The beneficial effects of this utility model are: This utility model has a simple structure, is easy to install, has low manufacturing cost, and can greatly improve the stress state of the tape under load, prevent the tape from being damaged and cracked, and extend the service life of the tape. Attached Figure Description
[0013] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.
[0014] Figure 1 This is a schematic diagram of the existing deep groove type idler frame; Figure 2 This is a schematic diagram of the structure of this utility model; Figure 3 for Figure 2 A top view after the tape has been removed. Detailed Implementation
[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.
[0016] See Figure 2 The deep groove type idler frame provided by this utility model includes a horizontal mounting plate 200, on which a support frame 300 is welded. The support frame 300 is composed of support frames 310, 320, 330, 340, and 350. A first idler 400, a second idler 500, a third idler 600, a fourth idler 700, and a fifth idler 800 are sequentially mounted on the support frame.
[0017] The support frame 300 is used to mount the first idler 400, the second idler 500, the third idler 600, the fourth idler 700 and the fifth idler 800, and to connect the first idler 400, the second idler 500, the third idler 600, the fourth idler 700 and the fifth idler 800 into one unit.
[0018] Support frame 310 is composed of two bent steel plates, symmetrically welded to the left and right sides of the horizontal mounting plate. A reinforcing rib plate is welded to the inner center of support frame 310. Support frame 320 is composed of two bent steel plates, symmetrically welded to the left and right sides of the horizontal mounting plate. Support frame 330 is composed of two bent steel plates, symmetrically welded to the left and right sides of the horizontal mounting plate. Support frame 340 is composed of two bent steel plates, symmetrically welded to the left and right sides of the horizontal mounting plate. Support frame 350 is composed of two vertical steel plates, symmetrically welded to the left and right sides of the horizontal mounting plate. The support frames are numbered 310, 320, 330, 340, and 350 from the sides to the middle.
[0019] The first idler roller 400 is mounted on support frames 310 and 330, the second idler roller 500 is mounted on support frames 320 and 340, the third idler roller 600 is mounted on support frame 350, the fourth idler roller 700 is mounted on support frames 320 and 340, and the fifth idler roller 800 is mounted on support frames 310 and 330.
[0020] After the idler rollers are installed, the angle between the first idler roller 400 and the second idler roller 500 can be 15°~30°, and the angle between the fourth idler roller 700 and the fifth idler roller 800 can also be 15°~30°; the angle between the second idler roller 500 and the third idler roller 600 can be 30°~45°, and the angle between the third idler roller 600 and the fourth idler roller 700 can also be 30°~45°.
[0021] In addition, to allow the first idler roller 400, second idler roller 500, third idler roller 600, fourth idler roller 700, and fifth idler roller 800 to rotate independently on their respective support frames and to be flexibly assembled and disassembled, support frames 310, 330, and 350 are welded to the front side of the horizontal mounting plate 200, and support frames 320 and 340 are welded to the rear side of the horizontal mounting plate 200. (See...) Figure 3 .
