Detailed Description

Referring to the attached

drawings

1, 2 and 4, the utility model provides a coal plate knot cleaning device, including quick-witted case 1, be provided with two sets of knife rest assemblies, the inside rotary driving device who drives the knife rest assembly rotation respectively in the bottom both sides of quick-witted case 1. The blade carrier assembly described above includes a spindle 11 and a plurality of blades 12 arranged along the circumference of the spindle 11. A connecting arm 13 is arranged on one side of the case 1, and the rotating shaft 11 is limited on the connecting arm 13 through a bearing in a rotating way. The rotation driving device includes a driving motor 14 and an intermediate transmission assembly disposed between an output shaft of the driving motor 14 and the rotating shaft 11. The intermediate transmission assembly comprises a transmission shaft arranged in the case 1, a gear transmission set arranged between the transmission shaft and the driving motor 14 and a chain wheel and chain transmission set arranged between the transmission shaft and the rotating shaft 11. Each group of tool rest assemblies are respectively matched with a rotary driving device, so that the whole device can be driven to walk in a certain range when the rotating shaft 11 rotates at a low speed, and blockage cleaning operation can be realized when the rotating shaft rotates at a high speed.

The top of the case 1 is provided with a traction plate 10, and the traction plate 10 is provided with a plurality of connecting holes for connecting a traction rope and a power supply and control line which are arranged above and used for controlling the whole operation position of the whole device.

Since the coal sheet is hard and the blade 12 may lift the working side of the entire apparatus due to the reaction force when contacting the sheet, a weight assembly including a weight 2 and a reciprocating driving device for driving the weight 2 to move in the longitudinal direction of the cabinet 1 is provided in the cabinet 1. The reciprocating driving device comprises a reciprocating driving motor, a screw rod 3 connected with an output shaft of the reciprocating driving motor, a screw nut 4 matched with the screw rod 3 and connected with a counterweight 2, and a counterweight guide rod 5 arranged in the case 1.

When in operation, the balance weight 2 moves to the side of the tool rest component at the operation side, an acting force is applied to the balance weight, so that the blade 12 is easy to go deep into a plate joint layer when rotating rapidly, the plate joint layer is loosened and then cracked, and then blockage removal is realized; of course, a remote intelligent positioning device can be installed on the device, and automatic comprehensive layer-passing cleaning is achieved through manual computer control.

Referring to fig. 2-4, because the reaction force of the blade 12 during clearing the blockage is a component force which can make the chassis 1 move in the axial direction thereof in addition to a component force which makes the whole chassis 1 move upwards, the component force can affect the clearing effect, a positioning assembly driven by the counterweight 2 is arranged on the bottom plate 1-1 of the chassis 1, the positioning assembly comprises a toothed plate 6, two guide shafts 7 arranged on the toothed plate 6, guide sleeves 8 arranged on the bottom plate 1-1 and matched with the guide shafts 7, rollers 9 arranged on the tops of the guide shafts 7 and a pressure spring 15 connecting the guide shafts 7 and the bottom plate 1-1, and the bottom edge of the counterweight 2 is arc-shaped. The teeth plate 6 is driven to penetrate into the sheet metal layer by contacting the roller 9 and pressing down the roller 9 during movement of the counterweight to the carriage assembly, so that the blade 12 operates better. At the same time, the blade 12 on the other side can also be controlled to rotate to counteract the applied force component.

Two groups of positioning assemblies are arranged on the bottom plate 1-1 and respectively correspond to the two groups of tool rest assemblies. In the normal state the counterweight 2 is in the middle position of the two sets of positioning elements. When determining which side of the carriage assembly to use, the reciprocating drive drives the counterweight toward that side of the carriage assembly and simultaneously drives the castellated plate 6 in the positioning assembly downward.

The utility model discloses a coal board knot cleaning device use as follows, at first transfers whole device to the top on the board knot layer that needs the clearance operation through the haulage rope, carries out the coarse positioning of position. And then the rotating shaft 11 is driven to rotate slowly by controlling the driving motor 14 so that the whole device moves to a more accurate working position. The operation is then started by first identifying the tool holder assembly to be operated and, once identified, the reciprocating drive means drives the counterweight 2 to move to one side of the assembly and simultaneously drives the toothed plate 6 to penetrate the sheet metal structure. Then the driving motor 14 at the working side drives the rotating shaft 11 to rotate rapidly, so that the blade 12 breaks the plate junction layer, and the inclined plate junction layer is cracked under the gravity and the vibration during the operation of the device, thereby realizing blockage removal. After the blockage is cleared, the counterweight 2 is reset, and the device is lifted and moved to the next operation place through the traction rope.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
