Description

Technical Field

[0001] The utility model relates to the field of coal preparation transportation, in particular to a new type of lower supporting roller for tubular belt transportation. Background Technique

[0002] For the coal transportation in coal preparation plants, the tubular belt is chosen for transportation because some transports need to cross workshops outdoors, and due to the relatively large height from the ground, using conventional belt transportation is prone to deviation. This poses a risk of material leakage. If there are pedestrians passing below, it is very easy to cause accidents such as pedestrians being injured by falling objects. Moreover, due to the environmental protection governance advocated by the country, the tubular belt can well avoid the harm of coal dust to the environment. However, since the physical properties of the belt have changed for the tubular belt and it needs to be rolled into a tube, the tightness problem on both sides of the belt is relatively prominent. Previously, it was easy for the edges of the tubular belt to enter the connection of the supporting rollers, causing the tubular belt to deform and damaging the belt edges. If the on-site driver does not conduct inspections well and the wear time is long, it will cause the belt to tear. Content of the Utility Model

[0003] The purpose of the utility model is to provide a new type of lower supporting roller for tubular belt transportation to solve the above technical problems.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions: A new type of lower supporting roller for tubular belt transportation, including a bracket, a front support plate, a rear support plate, a channel, a tubular belt supporting roller group, a limiting block, and a pre-shaped supporting roller. The middle part of the bracket is installed on the front support plate, the rear support plate is installed behind the front support plate, the channel is opened in the middle parts of the front support plate and the rear support plate, the tubular belt supporting roller group is installed in the channel between the front support plate and the rear support plate, the limiting block is installed on the front side of the front support plate through the bracket, and the pre-shaped supporting roller is installed at the bottom of the front side of the front support plate through the limiting block.

[0005] Based on the above technical solutions, the pre-shaped supporting roller includes a base, a limiting groove, a supporting roller support plate, a sliding groove, a rotating shaft, a lower supporting roller, and a pre-shaped groove. Limiting grooves are respectively opened at the left and right ends of the base, the supporting roller support plates are respectively fixed at the left and right parts at the top of the base, the sliding groove is opened in the middle of the top of the supporting roller support plate, the rotating shaft is rotatably connected to the sliding groove, the lower supporting roller is installed in the middle of the rotating shaft, and the pre-shaped groove is opened in the middle of the side end of the lower supporting roller and corresponds to the front side of the lower part of the channel.

[0006] Based on the above technical solutions, the lower supporting roller corresponds to the front side of the tubular belt supporting roller group through the pre-shaped groove.

[0007] Compared with the prior art, the utility model has the following advantages: By installing a pre-forming roller on the front side of the tubular belt idler group for conveying the tubular belt, the lower idler with a pre-forming groove pre-forms the tubular belt before it enters the tubular belt idler group, avoiding the problem that the edge of the tubular belt enters the connection of the idlers, causing the tubular belt to deform and damaging the belt edge.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0012] The following further elaborates on the utility model in detail in conjunction with the drawings and specific embodiments.

[0013] As Figures 1 to 3 shown, a new type of lower idler for tubular belt transportation includes a support 1, a front support plate 2, a rear support plate 3, a channel 4, a tubular belt idler group 5, a limit block 6, and a pre-forming roller 7. The middle of the support 1 is installed on the front support plate 2, the rear support plate 3 is installed on the rear side of the front support plate 2, the channel 4 is opened in the middle of the front support plate 2 and the rear support plate 3, the tubular belt idler group 5 is installed in the channel 4 through the front support plate 2 and the rear support plate 3, the limit block 6 is installed on the front side of the front support plate 2 through the support 1, and the pre-forming roller 7 is installed at the bottom of the front side of the front support plate 2 through the limit block 6.

[0014] The pre-forming roller 7 includes a base 8, a limit groove 9, an idler support plate 10, a chute 11, a rotating shaft 12, a lower idler 13, and a pre-forming groove 14. The left and right ends of the base 8 are respectively provided with limit grooves 9, the idler support plates 10 are respectively fixed at the left and right parts of the top of the base 8, the chute 11 is opened in the middle of the top of the idler support plate 10, the rotating shaft 12 is rotatably connected to the chute 11, the lower idler 13 is installed in the middle of the rotating shaft 12, and the pre-forming groove 14 is opened in the middle of the side end of the lower idler 13, and the pre-forming groove 14 corresponds to the front side of the lower part of the channel 4.

[0015] The lower idler 13 corresponds to the front side of the tubular belt idler group 5 through the pre-forming groove 14.

[0016] Working principle of the present utility model: During use, the tubular belt for conveying coal passes through the pre-shaped idler 7. Under the pressure of the coal, the middle part of the belt fits the pre-shaped groove 14, causing the left and right parts of the belt to warp upwards to fit the tubular belt idler set 5, facilitating the formation and maintenance of the tubular belt when passing through the tubular belt idler set 5 via the channel 4, preventing the edges of the tubular belt from entering the connection of the idlers and avoiding deformation of the tubular belt.

[0017] The above is the preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the teachings of the present utility model, any changes, modifications, substitutions, and variations made to the implementation manners without departing from the principles and spirit of the present utility model still fall within the protection scope of the present utility model.
