CN201694608U - E-shaped bolt of scraper conveyor - Google Patents

Abstract

The utility model discloses an E-shaped bolt of a mining scraper conveyor, which comprises a connecting plate (4) and a bolt (3). The bolt (3) and the connecting plate (4) are split. The connecting plate (4) comprises an upper portion (1) and a lower portion (2) stamped from a metal sheet. The upper portion (1) and the lower portion (2) are matched and welded into a body. Bolt holes are arranged on the connecting plate (4). The bolt (3) passes through the bolt hole. The bolt holes of the upper portion (1) and the lower portion (2) correspond to each other and are matched with a nut of the bolt (3). The utility model is reduced 30 per cent in weight compared with the original casting structure, thereby greatly reducing frictional force between the scraper and the middle groove. In addition, the manufacturing cost is less than that of the original casting structure.

Description

A kind of E type bolt of slat conveyer

Technical field

The utility model relates to a kind of E type bolt, especially a kind of E type bolt of mine flight conveyer.

Background technology

The scraper plate of mine flight conveyer be by a kind of E type bolted connection on the chain of slat conveyer, the scraper plate machine is to drive sprocket wheel by retarder in work, sprocket wheel drive chain and scraper plate the middle plate of intermediate channel up and down between circulating motion, coal is transported to an other end from an end of scraper plate machine.The E type bolt of mine flight conveyer uses steel mostly at present, adopt the foundry technique one-shot forming, weight is at 2.5-10kg, if calculate according to one 100 meters long slat conveyers, one cover slat conveyer needs about 660 E type bolts, and these E type bolt total weightes are between 1650-6600kg.The increase of E type bolt weight directly causes the increase of complete machine weight, has not only wasted raw MAT'L, and slat conveyer need pay more idlely in work, causes more energy loss.The E type bolt friction force that can reduce scraper plate and intermediate channel greatly that means in light weight cuts down the consumption of energy, thereby improves the work efficiency of scraper plate machine.

The utility model content

The purpose of this utility model provides a kind of E type bolt in light weight, slat conveyer cheaply.

For solving above technical matters, the technical scheme that the utility model is taked is:

A kind of E type bolt of slat conveyer comprises connecting panel, bolt, and bolt and connecting panel are the branch body structures, and bolt hole is set on the connecting panel, and bolt passes from bolt hole; Connecting panel is to be made of mo(u)ld top half that is stamped to form with sheet metal and mo(u)ld bottom half, and mo(u)ld top half and mo(u)ld bottom half cooperatively interact and be integrally welded, and the bolt hole of mo(u)ld top half and mo(u)ld bottom half cooperates in correspondence with each other and with the nut of bolt.

Owing to adopted technique scheme, the obtained technological advance of the utility model is:

Take structure of the present utility model, the more former cast structure of product weight alleviates 30%, can reduce the friction force of scraper plate and intermediate channel greatly, and productive costs is lower than former cast structure.The integrally welded intensity of connecting panel that can guarantee of mo(u)ld top half and mo(u)ld bottom half reaches cast-in-block intensity.

Description of drawings

Fig. 1 is the structural representation of the E type bolt of slat conveyer;

Among the figure: 1, mo(u)ld top half, 2, mo(u)ld bottom half, 3, bolt, 4, connecting panel.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further details:

As shown in Figure 1, E type bolt of the present utility model comprises connecting panel 4, bolt 3; Bolt 3 is branch body structures with connecting panel 4, and machine-shaping is used in combination then respectively.On the connecting panel 4 bolt hole is set, bolt 3 passes from bolt hole during use.Connecting panel 4 is to be made of mo(u)ld top half 1 and mo(u)ld bottom half 2, mo(u)ld top half 1, mo(u)ld bottom half 2 are used the sheet metal punch forming respectively, their the shape size and the position of bolt hole cooperatively interact, mo(u)ld top half 1 is last, mo(u)ld bottom half 2 is following, integrally welded after mo(u)ld top half 1 and the mo(u)ld bottom half 2 assembly groups, the bolt hole of mo(u)ld top half 1, mo(u)ld bottom half 2 cooperates in correspondence with each other and with the nut of bolt 3.

Claims (1)

1. the E type bolt of a slat conveyer comprises connecting panel (4), bolt (3), it is characterized in that: bolt (3) is the branch body structure with connecting panel (4), and connecting panel is provided with bolt hole on (4), and bolt (3) passes from bolt hole; Connecting panel (4) is to be made of the mo(u)ld top half that is stamped to form with sheet metal (1), mo(u)ld bottom half (2), and mo(u)ld top half (1) and mo(u)ld bottom half (2) cooperatively interact and be integrally welded, and the bolt hole of mo(u)ld top half (1) and mo(u)ld bottom half (2) cooperates in correspondence with each other and with the nut of bolt (3).
