The scheme relates to an arc-shaped protective curtain assembly 300 for a saw blade of a mine bar stone machine, which is arranged between a main spindle box 200 and a machine frame 100 of the mine bar stone machine. As shown in fig. 5, the headstock 200 is mounted on the frame 100 and can be moved up and down on the frame 100. The headstock 200 has a semicircular housing formed in the housing for the saw blade 24, and the semicircular housing has a semicircular inner housing wall 212 (see fig. 2 to 3). The housing 100 is shown in figures 2-3 for simplicity.
As shown in fig. 1-4, the protective curtain assembly 300 includes a protective curtain 31, an arc interlayer 32 and a telescopic control mechanism.
The arc interlayer 32 is arranged on the inner wall 212 of the headstock 200, and the arc interlayer 32 has a semi-arc structure corresponding to the inner wall of the headstock. In the embodiment shown, the circular sandwich 32 is formed by the inner box wall 212 of the headstock 200 and the semi-circular clamping plate 322, and the semi-circular clamping plate 322 is sleeved on the inner side of the inner box wall 212 with a gap therebetween, thereby forming a sandwich structure with the circular sandwich 32. The semi-circular arc clamping plate 322 is fixed by being fixedly and hermetically connected with the box inner wall 212 through the two side plates 35 as shown in fig. 4. In order to facilitate the assembly of the protective curtain 31 in the arc interlayer 32, at least one of the two side plates 35 is an arc-shaped sheet structure, which is detachably installed between the box inner wall 212 and the semi-arc clamping plate 322, and of course, the other side plate may be formed by the box side wall of the headstock 200. The arc sandwich layer 32 thus constructed is closed on both sides, and the protective curtain 31 is stably sandwiched between the arc sandwich layer 32. The two ends of the arc interlayer 32 are open, that is, the arc interlayer 32 has two lower ports 320.
The protective curtain 31 has an upper end 311 and a lower end 312 in the circular-arc interlayer 32. The lower end 312 of the protective curtain 31 extends from the lower port 320 of the circular arc interlayer 32 and is fixedly connected to the rack 100, and specifically, the position fixedly connected to the rack 100 is a position correspondingly below the lower port 320 (see fig. 3), i.e., is connected to the base position of the rack 100. The semicircular chamber of the headstock 200 has two sides (horizontal left and right sides in fig. 2) corresponding to the plane of the saw blade 24, and the dust and splashed water droplets generated during the operation of the saw blade 24 are mainly at the two sides, and herein, corresponding to the structure of the semicircular arc interlayer 32, the protective curtain 31 has two sets (only one set on the right side is shown in fig. 2) oppositely arranged, and the two sets are respectively clamped in two symmetrical arc segments of the arc interlayer 32.
The telescopic control mechanism is connected with the protective curtain 31, specifically connected with the upper end 311 of the protective curtain 31, and is used for driving the protective curtain 311 to automatically slide out of the arc interlayer 32 along with the ascending of the spindle box 200 and automatically retract into the arc interlayer 32 along with the descending of the spindle box 200. The preferred embodiment is given in which the telescoping control mechanism comprises a pulley member 33 and a cable 34. A through hole 321 is formed in a side wall of the arc interlayer 32 near the upper end (in a specific embodiment, the through hole 321 is formed in the box inner wall 212), the pulley member 33 is fixedly installed at the position of the through hole 321, the upper end of the steel wire rope 34 is fixed to the rack 100, and specifically, the upper end of the steel wire rope 24 extends upward and is fixed to the top of the rack 100 (shown in fig. 2-3 in a simplified manner). After bypassing the pulley member 33, the cable 34 extends into the through hole 321 to connect with the protective curtain 31. The lower end of the protective curtain 31 is fixed, the upper end is tensioned by a steel wire rope 34, the middle is guided by a pulley member 33, and the protective curtain 31 is always in a properly tensioned and smoothly displaceable spreading state. In order to enhance the structural strength of the telescopic control mechanism and to drive the protective curtain 31 to move smoothly and reliably, the pulley member 33 and the wire rope 34 are provided with two sets side by side, and two sets side by side are provided corresponding to the through hole 321. Each protective curtain 31 is telescopically movably coupled by two sets of pulley members 33 and wire ropes 34.
The protective curtain assembly 300 has a simple structure and a flexible design, and the protective curtain 31 is simply and concealably arranged in the arc interlayer 32. When the bar stone machine is in operation, the headstock 200 drives the saw blade 24 to move up and down, and a gap between the headstock 200 and the machine frame 100 changes along with the movement. When the main spindle box 200 drives the saw blade 24 to ascend, a gap between the main spindle box 200 and the rack 100 is enlarged, at the moment, under the guiding action of the pulley member 33, the lower end of the steel wire rope 34 bypasses the pulley member 33 and is pulled into the arc interlayer 32, the lower end of the corresponding protective curtain 31 gradually extends out of the arc interlayer 32, and the enlarged gap between the main spindle box 200 and the rack 100 is completely shielded by the extended protective curtain 31 for effective blocking and sealing. When the headstock 200 drives the saw blade 24 to descend, a gap between the headstock 200 and the frame 100 is reduced, at this time, under the guiding action of the pulley member 33, the wire rope 34 is gradually pulled out of the arc interlayer 32, the lower end of the corresponding protective curtain 31 is gradually pulled into the arc interlayer 32, and the reduced gap width between the headstock 200 and the frame 100 corresponds to the width of the protective curtain 31.
Therefore, the gap between the spindle box 200 and the frame 100 changes along with the lifting of the spindle box 200, and meanwhile, the protective curtain 31 can automatically and correspondingly stretch relative to the arc interlayer 32, so that the effect of effectively sealing the gap in real time in any state is realized. The protective curtain 31 is equivalent to the part of the box wall of the main spindle box 200 extending to the rack 100, so that no matter the main spindle box 200 and the saw blade 24 are lifted and lowered at any position, the saw blade 24 is horizontally positioned on the part above the rack 100, the part is effectively protected and isolated by a continuous protective wall formed by the box wall of the main spindle box 200 and the protective curtain 31, stone dust generated in the sawing of the saw blade on the stone can be effectively blocked in the protective wall, the problems of dust pollution and the like are solved, and the normal operation and the service life of the stone bar machine are ensured.
The arc interlayer 32 has an inner side wall and an outer side wall corresponding to the inner interlayer and the outer interlayer, and in the above preferred embodiment, the box inner wall 212 is used as the outer side wall of the arc interlayer 32, and the semi-arc clamp plate 322 is used as the inner side wall of the arc interlayer 32. Preferably, the two ends of the inner side wall (the semicircular arc clamping plate 322) extend downwards to exceed the outer side wall (the box inner wall 212), and the two ends are folded outwards to form folding edges 3221. The folding edge 3221 functions to change the opening of the lower port 320 from the original downward direction to the outward direction, so as to avoid the insufficient sealing at the lower port 320 from affecting the protection effect; of course, the folding edge 3221 is also beneficial to the effective leaning action of the protective curtain 31, and meanwhile scrapes and separates dust and water drops attached to the inner side surface of the protective curtain, thereby avoiding the problems that the dust and the water drops enter the arc interlayer 32 along with the protective curtain 31 to affect the normal use and the like. The edge of the turning edge 3221 may further be provided with a scraping brush structure for facilitating scraping.
Further, in order to enhance the side sealing performance of the circular sandwich 32 and the lower port 320, it is preferable that both sides of the turned edge 3221 are provided with edge protecting covering edges, which overlap the extended portions of both end portions of the turned edge 3221 and the inner sidewall (the semicircular arc clamping plate 322). Preferably, the edge cover is formed by extending the two ends of the two side plates 35 downward to form an edge cover 351 connected to the turned edge 3221.
The above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made within the scope of the claims of the present invention should fall within the scope of the claims of the present invention.
