Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses novel two leaf spring sintering machine glide slope 2. Referring to fig. 1, a novel dual leaf spring sintering machine downslide 2 includes a support beam 1 and a downslide 2 mounted on the support beam 1. The lower slideway 2 comprises a slideway block 21 arranged along the length direction of the supporting beam 1, and a roller 22 arranged perpendicular to the length direction of the supporting beam 1 is arranged on the top of the slideway block 21.

In actual use, the trolley slide plate of the sintering machine moves above the lower chute 2, the lower chute 2 bears the pressure from the trolley slide plate, and the rollers 22 can change the sliding friction force between the trolley slide plate and the lower chute 2 into the rolling friction force, so that the abrasion between the trolley slide plate and the lower chute 2 is reduced, and the service life of the lower chute 2 is prolonged.

Referring to fig. 1 and 2, the plurality of slide rail blocks 21 are provided, a clamping groove 212 is formed in the middle of one side surface of one end of each slide rail block 21, a clamping block 213 is arranged in the middle of the other end of each slide rail block 21, and the adjacent slide rail blocks 21 are connected together in a clamping fit mode through the clamping blocks 213 and the clamping grooves 212. Each slide block 21 is provided with a plurality of vertical mounting bolts 23, and two of the embodiments are specifically described as examples. Two mounting bolts 23 vertically penetrate through the support beam 1 and the slide block 21 upwards to fix the slide block 21 on the support beam 1.

In use, lower slide 2 can be in high temperature environment, and the rigidity of construction bolt 23 can descend this moment, and slide block 21 can take place the displacement, because use the mode of joint to connect between the adjacent slide block 21, so slide block 21 can not take place great displacement, reduces slide block 21 and the risk that the platform truck swimming plate bumps.

Referring to fig. 1 and 3, a plurality of mounting grooves 211 are formed at the top of the slide block 21, a roller 22 is inserted into the mounting grooves 211, and the roller 22 can rotate inside the mounting grooves 211.
