Description

Technical Field

[0001] The utility model relates to a structure for reducing the total height of a direct-connected mining circular saw machine. Background Art

[0002] Circular saws are mostly used in mining and stone mining. They generally include a machine base that can walk on the mine track, a lifting frame that carries the saw machine, and a lifting drive mechanism pivotally installed between the frame and the machine base. The saw machine also includes a motor, a spindle box, and a saw blade fixed on the spindle of the spindle box. The motor drives the saw blade on the spindle to rotate and cut. Figure 4 As shown, in the existing circular saw machine, a drag chain seat A3 is installed on the slide A1 of the spindle box and the drag chain support seat A2, and then the two ends of the drag chain A4 are respectively fixed on the slide and the drag chain seat. The drag chain is used to protect the relevant lines. However, such a structure easily leads to that when the height of the spindle box saw blade needs to be adjusted, the lifting cylinder will drive the spindle box A5 assembly to the highest point. Since one of the drag chain seats is fixed on the slide of the spindle box, the drag chain seat and the drag chain of the slide will also move upward, thereby hitting the upper connecting plate A6 of the frame. In order to prevent the drag chain seat and the drag chain from hitting the upper connecting plate, the total height of the four columns A7 needs to be increased, which will cause the center of gravity of the entire circular saw machine to move upward, resulting in poor stability and increasing the production cost of the machine. Utility Model Content

[0003] The present invention improves the above-mentioned problem, that is, the technical problem to be solved by the present invention is to provide a direct-connected mining circular saw machine with a reduced total height structure, effectively avoiding collision between the drag chain, the drag chain seat and the upper connecting plate of the frame, reducing the height of the frame column, and improving the stability of the overall machine.

[0004] The utility model is constructed as follows: it includes an upper connecting plate, a column, a spindle box, and a lifting cylinder of a circular saw machine frame; a hanging fixed angle iron is fixed below the upper connecting plate; a drag chain seat fixing plate is provided on the upper front part of the spindle box; a drag chain seat is installed on the inner side of the lower part of the hanging fixed angle iron and the lower part of the drag chain seat fixing plate; a drag chain is provided between the two drag chain seats.

[0005] Furthermore, a connecting plate is fixed below the upper connecting plate, and the connecting plate and the suspension fixing angle iron, and the suspension fixing angle iron and the drag chain seat are connected via bolt and nut assemblies.

[0006] Furthermore, the cross section of the hanging fixing angle iron is L-shaped.

[0007] Furthermore, a hoisting mechanism is provided on the top of the circular saw machine frame, and the hoisting mechanism includes an L-shaped hanger, a slide rail is provided on the L-shaped hanger, a slider is provided on the slide rail, and an electric hoist is installed on the slider.

[0008] Compared with the prior art, the utility model has the following beneficial effects: the device has a simple structure, a reasonable design, and is easy to use. By arranging a hanging fixed angle iron and a drag chain seat fixing plate, the two drag chain seats are fixed on the hanging fixed angle iron and the drag chain seat fixing plate respectively. As a result, the drag chain and the drag chain seat are both below the spindle box slide. When the lifting cylinder drives the slide plate spindle box assembly to move upward to the highest point, no parts on the spindle box will touch the upper connecting plate. There is no need to lengthen the four columns of the frame, which greatly reduces the height of the columns, thereby lowering the overall center of gravity of the circular saw machine and improving the stability of the machine. At the same time, it reduces manufacturing costs and manufacturing time, improves economic benefits, shortens delivery cycles, and improves product satisfaction. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0014] Example: Figure 1-3 As shown, a direct-connected mining circular saw machine is provided with a total height reduction structure, including an upper connecting plate 1 of a circular saw machine frame, a column 2, a spindle box 3, a lifting cylinder 4, and a slide plate 5. The lifting cylinder is arranged on the upper connecting plate, and a hanging fixed angle iron 6 is fixed below the upper connecting plate. The hanging fixed angle iron extends downward to the upper middle part of the front of the spindle box, and a drag chain seat fixing plate 7 is installed on the upper front part of the spindle box. The drag chain seat fixing plate does not exceed or slightly exceeds the upper surface of the spindle box, and a drag chain seat 8 is fixed to the inner side of the lower part of the hanging fixed angle iron and the lower part of the drag chain seat fixing plate. A drag chain 9 is provided between the two drag chain seats, and both ends of the drag chain are fixed to the drag chain seats; the drag chain is in a "U" shape downward as a whole.

[0015] By setting a hanging fixed angle iron and a drag chain seat fixing plate, the two drag chain seats are fixed on the hanging fixed angle iron and the drag chain seat fixing plate respectively. As a result, the drag chain and the drag chain seat are both located below the spindle box slide. When the lifting cylinder drives the slide plate and the spindle box assembly to move upward to the highest point, no parts on the spindle box will touch the upper connecting plate. There is no need to lengthen the four columns of the frame, which greatly reduces the height of the columns, thereby lowering the overall center of gravity of the circular saw machine and improving the stability of the machine. At the same time, it reduces manufacturing costs and manufacturing time, improves economic benefits, shortens delivery cycles, and improves product satisfaction.

[0016] In an embodiment of the present invention, a connecting plate 10 is fixed below the upper connecting plate, and the connecting plate and the suspension fixing angle iron, and the suspension fixing angle iron and the drag chain seat are connected via a bolt and nut assembly 11; the bolt and nut assembly includes bolts and nuts.
