Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] see Figure 1-Figure 15 , the main shaft structure of the large-scale stone sawing machine, the large-scale stone sawing machine includes a saw frame 7 that slides up and down between the front column 6 and the rear column 17 (saw frame slides up and down see Figure 15 F arrow), the saw frame is provided with several saw blades / strips 8; the main transmission structure includes a main shaft 1 connected to the saw frame, and the main shaft is connected to the drive motor 13; Saw frame connection. The outer end of the main shaft 1 is also provided with a balance wheel 2, see Figure 6-Figure 8 . A counterweight 4 is arranged on the main shaft 1; the counterweight is fan-shaped, and the angle between the two sides of the fan is 120°-130°, see Figure 9 and Figure 10 .

[0029] On the same plane of the eccentric block 12, the main shaft conne...

Abstract

The invention relates to a main shaft structure of a large-scale stone sawing machine, the large-scale stone sawing machine comprises a saw frame which is arranged between a front upright post and a rear upright post in a way of sliding up and down, and a plurality of saw blades are arranged on the saw frame; a main transmission structure comprises main shafts in transmission connection with the saw frame, and the main shafts are in transmission connection with driving motors; and the main shafts are connected with the saw frame through eccentric blocks and connecting rods. The left side and right side of the saw frame are in transmission connection with the driving motors through the main shafts respectively; and the two main shafts are consistent in rotational speed. The main shafts are in transmission with the saw frame through the eccentric blocks and the connecting rods, thereby realizing up and down operation of the saw frame; furthermore, the two sides of the saw frame are in transmission connection with the main shafts which operate synchronously, and each main shaft is driven by the driving motor respectively, thereby enabling load to be shared on each driving motor; and simultaneously, a balancing wheel, a balancing weight and a belt pulley with a weight balancing function are arranged on each main shaft, thereby enabling the vertical up and down operation of the saw frame to be smoother. The structure is simple and reasonable, the operation is smooth, the stone sawing speed is fast, and the effects are good.

Description

technical field [0001] The invention relates to a stone sawing machine, in particular to a main shaft structure of a large stone sawing machine mainly suitable for outdoor mines. Background technique [0002] Chinese patent document number CN2562952 discloses a kind of hanging type multi-frame vertically moving stone sawing machine on July 30, 2003. Including frame, motor, reducer, rotating shaft, frame with gang saw, feeding cart and feeding cart guide rail, motor and reducer are set on the frame, rotating shaft is composed of at least 2 crankshafts connected, frame is connected to crankshaft through connecting rod Connected, the frame is a vertical running track. The electric motor of this structure drives multiple frames, resulting in a large load on the electric motor, low stone sawing speed and low force, and cannot be used for sawing large stones. Contents of the invention [0003] The object of the present invention is to provide a main shaft structure of a large-...
