Description

Technical Field

[0001] This utility model belongs to the field of mechanical structures, and in particular relates to a multi-directional moving device for crushing equipment. Background Technology

[0002] A classifying crusher, also known as a double-toothed roll crusher, is a crushing device that uses a pair of rotating crushing toothed rolls to break materials from large pieces to smaller pieces under the action of compression and shearing forces. A significant characteristic of this crusher is that it only crushes materials larger than the gap between the toothed rolls, while materials smaller than the gap pass through directly. Therefore, the classifying crusher has the dual functions of crushing and classifying. Due to its large processing capacity and uniform output particle size, the classifying crusher has been widely used in coal, limestone, metal, non-metal, and building materials industries.

[0003] The existing crushing equipment has a feeding mechanism connected directly above it, which is inconvenient for maintenance and observation. When maintenance is required, the crushing equipment must be moved away from directly below the feeding port to expose the crusher inlet and inspect the crushing teeth inside the crushing chamber. At the same time, due to the large weight of the crusher, the current method of movement is usually to lay rails on the factory floor and set track wheels under the crusher. The track wheels drive the crusher to move on the rails. The guide rails and crushing rollers are generally arranged parallel or perpendicularly, which means that the movement of the crusher is limited to reciprocating movement along or perpendicular to the crushing rollers. Therefore, this method results in the existing crusher having a single direction of movement, which can only move according to the direction of the rails.

[0004] In actual maintenance, the crusher needs to be adjusted to a certain angle relative to the feeding mechanism to check the crushing teeth of the crushing equipment or to observe the working status of the crushing teeth when the feeding mechanism is feeding. The existing single movement method cannot adjust the angle of the crusher, which restricts operation during maintenance, increases the difficulty and time cost of maintenance, and is time-consuming and labor-intensive.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] This utility model provides a multi-directional moving device for crushing equipment, including: a hydraulic cylinder 1, a hexagonal nut 2, a rack 3, a gear 4, a frame 5, an internal gear ring 6, an external gear 7, a hexagonal head bolt 8, a spring washer 9, a flat washer 10, a wheel axle 11, a bushing 12, a traveling wheel 13, a lead screw 14, and a protective shell 15.

[0037] Because the crushing equipment is heavy, a large-sized traveling wheel structure is required, thus necessitating a power structure with high output force. A hydraulic cylinder is preferred, with its power output end connected to a rack 3, controlling the rack 3 to move back and forth (to...). Figure 1 (From a visual perspective, it moves left and right). The rack 3 meshes with the gear 4. The hydraulic cylinder 1 is placed on the upper surface of the frame 5 of the crushing equipment. The hydraulic cylinder 1 uses the rack 3 to drive the gear 4, thus forming a steering mechanism.

[0038] The gear 4 has a threaded hole in the middle, and the lead screw 14 passes through the threaded hole in the middle of the gear 4. There are several hexagonal nuts 2 on the top and bottom of the gear 4 to fix the position of the gear 4.

[0039] The lower surface of the frame 5 is provided with an external gear 7 and an internal gear ring 6. The external gear 7 and the internal gear ring 6 mesh with each other. The lead screw 14 is fixedly connected to the center position of the external gear 7, preferably by welding. The frame 5 has an opening, and the lead screw 14 passes through the opening on the frame 5.

[0040] The internal gear ring 6 is welded to the lower surface of the frame 5 and meshes with the external gear 7. When the frame 5 is raised, the internal gear ring 6 is lifted together with the frame 5. At this time, it separates from the internal gear ring 6 and drives the lead screw 14 to rotate by moving back and forth through the steering mechanism. This causes the external gear 7 to rotate with different numbers of teeth relative to the internal gear ring 6, thereby adjusting the orientation of the crusher's traveling wheel 13.

[0041] The external gear 7 is welded to the protective housing 15 as a whole. The protective housing 15 has shaft holes 111 on both sides. The wheel axle 11 passes through the shaft holes on both sides of the protective housing 15. A blocking structure is provided on the outside of the shaft hole. The blocking structure includes a hexagonal head bolt 8, a spring washer 9, a flat washer 10, and a side baffle 101. The blocking structure seals the wheel axle 11 in the shaft hole 111 to prevent the wheel axle 11 from falling out of the shaft hole 111. The side baffle is provided with a reserved hole to facilitate the passage of the hexagonal head bolt 8. The shaft holes on both sides of the protective housing 15 are provided with threaded holes that mate with the hexagonal head bolt 8. The traveling wheel 13 is set inside the protective housing 15.

[0042] The axle 11 is fitted with a bushing 12 along the circumferential direction, and a traveling wheel 13 is fitted on the outside of the bushing 12. The purpose of the bushing 12 is to reduce the friction of the traveling wheel 13 moving along the circumferential direction. There are two bushings 12 arranged opposite each other. Each bushing 12 is provided with a sleeve portion 121 and a side stop portion 122. The sleeve portion of the two bushings 12 is located between the outer surface of the axle 11 and the inner wall of the mounting hole of the traveling wheel. The side stop portions 122 are located on both sides of the sleeve portion 121. The side stop portions 122 of the two bushings 12 form a gap between the traveling wheel 13 and the inner wall of the protective housing 15. The side stop portions are used to prevent the traveling wheel 13 from directly rubbing against the inner wall of the protective housing 15 due to the left and right movement of the axle 11.

[0043] In practical use, this solution mentions four multi-directional moving devices, each installed on the crusher frame. When the crusher is under maintenance, and due to its large weight, the existing casters cannot be used directly to move it. Because of the weight, changing direction is difficult by pushing the casters. Therefore, a hydraulic lifting device, such as a jack, or a gantry crane in the factory is used to raise the crusher to reduce the stress on the wheels. After adjusting the wheel orientation, the crusher is lowered, and the internal gear ring 6 and external gear 7 disengage from their meshing state. This is achieved by controlling the four hydraulic... Cylinder 1 horizontally drives rack 3 to mesh with gear 4 and move horizontally back and forth. Gear 4 simultaneously drives external gear 7 to rotate clockwise or counterclockwise, which in turn drives the traveling wheel 13 to change direction through lead screw 14 and make it consistent with the direction that the crusher needs to turn and travel. Subsequently, the crushing equipment is pushed by external force, and the crushing equipment can move in the direction of the traveling wheel. At the same time, this solution sets four hydraulic cylinders for the four wheels. By driving the four hydraulic cylinders to move synchronously, the extension distance of the hydraulic rods of the four hydraulic cylinders can be controlled to be the same, thereby ensuring that the adjustment angle of the four wheels is consistent. The above hydraulic cylinder control method can be achieved using existing technology.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
