Description

Technical Field

[0001] This utility model relates to the field of mining equipment, and in particular to a bilaterally driven longitudinal movement mining saw. Background Technology

[0002] Mining saws are used in mining operations. They typically have two spindle boxes with oppositely oriented spindles to drive saw blades on both sides simultaneously for cutting, improving efficiency. During adjustment and tool setting, the two spindle boxes move longitudinally simultaneously under the drive of their respective hydraulic cylinders. Currently, the hydraulic cylinders driving the longitudinal movement of the spindle boxes are all single-sided. This single-sided drive leads to an imbalance of forces on both sides of the spindle box, resulting in poor stability. Ultimately, this causes uneven force on the saw blades, resulting in vibration and wobble, affecting cutting accuracy. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a mining saw with double-sided drive longitudinal movement, wherein the longitudinal movement of the spindle box is driven by double-sided longitudinal hydraulic cylinders to ensure force balance and good stability.

[0004] This utility model is implemented using the following scheme: a mining saw with bilateral drive longitudinal movement includes a base, on which a pair of columns are respectively provided on the left and right sides, and on each of the two pairs of columns are slides that can move up and down along the columns. Between the two slides are a front spindle box and a rear spindle box that can move back and forth relative to the slides. A pair of front longitudinal hydraulic cylinders for driving the front spindle box to move back and forth are connected between the top two sides of the front spindle box and the two slides. A pair of rear longitudinal hydraulic cylinders for driving the rear spindle box to move back and forth are connected between the top two sides of the rear spindle box and the two slides.

[0005] Furthermore, it also includes a top seat supported by a column at the top, with a support column at the middle of the upper side of the top seat, a rotating seat at the upper end of the support column, an I-beam fixedly connected to one side of the rotating seat, and a hand-pulled trolley mounted on the I-beam.

[0006] Furthermore, the hand-operated trolley includes a left side plate and a right side plate, with the I-beam passing through the middle of the left and right side plates. An upper support shaft connects the upper parts of the left and right side plates, and a lower support shaft connects the lower parts of the left and right side plates. A pair of left travel wheels are provided on the inner side of the middle of the left side plate, and a pair of right travel wheels are provided on the inner side of the middle of the right side plate. The left and right travel wheels are respectively placed on the upper side of the lower flanges on both sides of the I-beam. A hand-operated mechanism for driving the left travel wheels is provided on the outer side of the left side plate.

[0007] Furthermore, the hand-operated mechanism includes a drive wheel axle that passes through the left side plate and rotates with the left side plate. The outward end of the drive wheel axle is connected to a hand-operated chain disc, and the outward end of the drive wheel axle is connected to a drive gear. Each of the two left-hand wheels is provided with a driven gear that meshes with the drive gear.

[0008] Furthermore, a pair of driven wheel axles are fixedly connected to the inner side of the middle of the left side plate, and the left travel wheel is rotatably connected to the driven wheel axles; a pair of auxiliary wheel axles are fixedly connected to the inner side of the middle of the right side plate, and the right travel wheel is rotatably connected to the auxiliary wheel axles.

[0009] Furthermore, a hook shaft is connected between the lower parts of the left and right side plates, and there are two lower support shafts arranged one in front of the other, with the hook shaft located between the two lower support shafts.

[0010] Furthermore, a lifting cylinder is provided between the slide and the base to drive the slide to move up and down.

[0011] Furthermore, the support column is provided with a rotating sleeve in the middle, which rotates with it. A support block is fixed on the rotating sleeve, and a reinforcing plate is provided between the support block and the I-beam.

[0012] Furthermore, the reinforcing plate is triangular in shape, with its upper side connected to the I-beam by bolts, and its lower side welded to the support block.

[0024] like Figures 1-4 As shown, a dual-sided driven longitudinal movement mining saw includes a base 300. A pair of columns 400 are respectively provided on the left and right sides of the base. Each of the two pairs of columns has a slide block 500 that can move up and down along the columns. Between the two slide blocks are a front spindle box 600 and a rear spindle box 700 that can move back and forth relative to the slide blocks. The spindle of the front spindle box 600 faces forward, and the spindle of the rear spindle box 700 faces backward. The saw blade is not installed in the figure. A pair of front longitudinal hydraulic cylinders 610 for driving the front spindle box to move back and forth are connected between the top two sides of the front spindle box and the two slide blocks. A pair of rear longitudinal hydraulic cylinders 710 for driving the rear spindle box to move back and forth are connected between the top two sides of the rear spindle box and the two slide blocks. The front and rear longitudinal hydraulic cylinders are arranged in the front-back direction. The longitudinal movement of both the front and rear spindle boxes of this utility model mining saw is driven by double-sided longitudinal hydraulic cylinders. The double-sided synchronous drive helps to eliminate uneven load, prevent uneven force on the saw blade, ensure the force balance of the saw blade, extend the service life of the saw blade, improve the sawing stability, and ensure the cutting accuracy.

[0025] The rear end of the front longitudinal cylinder is hinged to the middle of the slide block, and the front end of the front longitudinal cylinder is hinged to the top of the front spindle box; the front end of the rear longitudinal cylinder is hinged to the middle of the slide block, and the rear end of the rear longitudinal cylinder is hinged to the top of the rear spindle box.

[0026] In this embodiment, a top seat 800 supported by a column is also included. A support column 810 is provided at the middle of the upper side of the top seat 800. A rotating seat 820 is provided at the upper end of the support column. A convex shaft is provided at the top of the support column. The rotating seat is fitted on the convex shaft and can rotate relative to it. An I-beam 200 is fixedly connected to one side of the rotating seat. A hand-pulled trolley 100 is provided on the I-beam.

[0027] In this embodiment, the hand-pulled trolley includes a left side plate 110 and a right side plate 120. An I-beam 200 passes through the middle of the left and right side plates. An upper support shaft 130 connects the upper parts of the left and right side plates, and a lower support shaft 140 connects the lower parts of the left and right side plates. A pair of left wheels 111 are provided on the inner side of the middle of the left side plate, and a pair of right wheels 121 are provided on the inner side of the middle of the right side plate. The left and right wheels rest on the upper sides of the lower flanges on both sides of the I-beam. A hand-pulling mechanism for driving the left wheels is provided on the outer side of the left side plate. This utility model effectively fixes the left and right side plates to form a rigid frame through the upper and lower support shafts, resulting in high structural strength, resistance to deformation, and ensuring a constant distance between the left and right side plates. This avoids the risk of the trolley falling due to side plate deformation, thus improving safety.

[0028] In this embodiment, the hand-operated mechanism includes a drive wheel axle 112 that passes through and rotatably engages with the left side plate.

Each of the two left-side traveling wheels is equipped with a driven gear 115 that simultaneously meshes with the drive gear. When the operator pulls the chain, the hand-operated chain disc rotates, which in turn drives the left-side traveling wheel 111 to roll along the flange of the I-beam via the drive gear 114 and driven gear 115. The right-side traveling wheel moves in coordination with the driven wheel. The power transmission path is simple, and the transmission efficiency is high.

[0029] In this embodiment, the driven gear and the left traveling wheel are integrated into one structure.

[0031] In this embodiment, a hook shaft 150 is also connected between the lower parts of the left and right side plates. There are two lower support shafts arranged one in front of the other. The hook shaft is located in the middle of the two lower support shafts. The two lower support shafts and one upper support shaft form a three-point support structure, which makes the overall structure more stable and reduces the lateral swing amplitude of the trolley on the I-beam. The hook shaft is used to lift the hoist.

[0032] In this embodiment, the upper support shaft, the lower support shaft, and the hook shaft are each provided with threaded portions at both ends. The threaded portions at both ends of the upper support shaft, the lower support shaft, and the hook shaft pass through the left side plate and the right side plate and are locked by nuts. The upper support shaft, the lower support shaft, and the hook shaft are also provided with shoulder portions at both ends to abut against the inner side of the left side plate and the right side plate.

[0033] In this embodiment, the hook shaft is provided with an annular limiting groove in the middle, and the hook of the hoist is hung in the annular limiting groove to avoid left and right swaying.

[0034] In this embodiment, a lifting cylinder 900 is provided between the slide and the base to drive the slide to move up and down.

[0035] In this embodiment, in order to improve the strength and stability of the I-beam, a rotating sleeve 830 is provided in the middle of the support column 810, which rotates with it.
