[0018] The technical solution of the present utility model will be clearly and completely described below in conjunction with the drawings and specific embodiments. As Figures 1-4As shown in the figure, an adjustable auxiliary support includes a base 1, an intermediate member with adjustable height, and a support plate 2, which are arranged in sequence from bottom to top; the base 1, the intermediate member, and the support plate 2 are detachably connected; two support blocks 4 are arranged on the support plate 2, and the two support blocks 4 are fixedly connected and the distance between them is adjustable. The component to be supported, such as the motor part of the power unit of a scraper conveyor, is arranged above the two support blocks 4. The height of the adjustable auxiliary support in this application and the horizontal distance between the two support blocks 4 are determined according to the height and size of the component to be supported. In the present utility model, the height of the adjustable auxiliary support is changed by adjusting the height of the intermediate member. The support width of the adjustable auxiliary support is changed by adjusting the distance between the two support blocks 4. The structure of the present utility model is simple and the adjustment range is larger. There are various methods for adjusting the height of the intermediate member. It can be directly replacing the intermediate members with different heights, or setting a multi-layer structure and changing the height by changing the number of layers and other common existing height adjustment methods.
[0019] The two support blocks 4 are slidably arranged on the upper surface of the support plate 2, and the two support blocks 4 are detachably connected by a double-headed screw 5 passing through both of them. Nuts are respectively arranged on the outer sides of the two support blocks 4 on the double-headed screw 5. The inner side of the support block 4 is the side where the two support blocks 4 are adjacent, and the outer side of the support block 4 is the side away from the other support block 4. Nuts are respectively arranged on the outer sides of the support blocks 4 on the double-headed screw 5, which limits the maximum horizontal distance between the two support blocks 4. Through holes for the double-headed screw 5 to pass through are arranged on the support blocks 4. Gaskets are arranged between the nuts and the support blocks 4. For the component to be supported with a cylindrical outer contour such as the power unit, or other shaped components. After the adjustable auxiliary support is arranged below it, as long as the maximum distance between the two support blocks 4 is limited, the support blocks 4 will not break away from the lower part of the component to be supported. Of course, other ways to adjust the distance between the support blocks 4 can also be adopted, such as being fixedly arranged on the support plate 2 by bolts and setting several more positions to facilitate distance adjustment. The support blocks 4 are slidably arranged on the support plate 2, and there are various ways of sliding connection, and any one can be selected.
[0020] A sliding groove 12 is provided on the upper surface of the support plate 2, and a sliding protrusion 40 is provided on the lower surface of the support block 4. The sliding protrusion 40 is slidably arranged in the sliding groove 12. Among them, limit blocks can be provided at both ends of the sliding groove 12, or both ends of the sliding groove 12 do not extend to the edge of the support plate 2 to prevent the support block 4 from slipping out of both ends of the sliding groove 12 under special circumstances. However, in actual working conditions, the weight of the component to be supported is relatively large, pressing on the adjustable auxiliary support, and the position of the support block 4 basically does not change. In order to simplify the structure, the limit blocks can also be not provided. The cross-section of the sliding groove 12 can be rectangular, and the shape of the sliding protrusion 40 is also rectangular. In order to prevent slipping out, the sliding groove 12 can also be set as an inverted T-shaped groove, and the shape of the protrusion is matched with it. In fact, due to the weight of the component to be supported itself, the support block 4 will not move horizontally or upward in the supported state, and an ordinary rectangular sliding groove 12 can meet the requirements, and the manufacturing is more convenient. In the attached drawing, the length of the sliding groove 12 is equal to the length of the support plate 2, and the limit blocks are not provided. This structure is simple to manufacture, low in cost, and can also meet the needs. Of course, it can also be that a guide rail is provided on the upper surface of the support plate 2, and a groove is provided on the lower surface of the support block 4, and the sliding connection between the support block 4 and the support plate 2 is realized through the cooperation between the groove and the guide rail. All these solutions are within the protection scope of the present utility model.
[0021] The upper surface of the support block 4 is an inclined surface or an arc surface. Two support blocks 4 are symmetrically arranged. The part where the two inclined surfaces are close to each other has a lower height, and the part where they are far from each other has a higher height; the support block 4 is in the shape of a right trapezoid. The shape of the right trapezoid only refers to the general shape. In fact, the upper surface of the support block 4 can be an arc surface or other smooth curved surfaces, and the lower surface of the support block 4 can be provided with a sliding protrusion 40. The support block 4 with an upper surface being an inclined surface or an arc surface is particularly suitable for the component to be supported with a cylindrical cross-section, such as the power unit motor of a scraper conveyor. The two support blocks 4 are arranged in mirror symmetry, and the adjustment of the vertical distance for supporting the cylindrical motor housing can be realized by adjusting the horizontal distance.
[0022] The middle part includes at least one layer of adjusting cushion plate 3. The base 1, the adjusting cushion plate 3, and the support plate 2 are detachably connected by at least two connecting bolts 6. In the present utility model, the height of the adjustable auxiliary support is changed by adjusting the number of layers of the adjusting cushion plate 3. Here, the connecting bolt 6 is preferably a full-thread bolt. The full-thread bolt is used to connect the support plate 2, the adjusting cushion block, and the base 1 together, and the full thread is for tightening the nut in any case.
[0023] An intermediate through groove 30 is provided at the middle position of the adjusting cushion plate 3, and the size of the intermediate through groove 30 accommodates the cross-sectional size of the support block 4. The part of the adjusting cushion plate 3 outside the intermediate through groove 30 serves as a support. The intermediate through groove 30 is provided to enable the removed adjusting cushion blocks to be sleeved on the support block 4 to prevent loss, and the loss can be effectively prevented through the installation method of the retaining ring. There can be one or two intermediate through grooves 30 on the adjusting cushion plate 3. One intermediate through groove 30 sleeves one support block 4, or one intermediate through groove sleeves two support blocks 4.
[0024] Through holes are respectively provided at the positions of the adjusting cushion plate 3 and the support plate 2 corresponding to the connecting bolts 6, and a stepped through hole 10 is provided at the position of the base 1 corresponding to the connecting bolts 6. The stepped through hole 10 includes a square hole provided at the bottom of the base 1 to prevent the connecting bolts 6 from rotating and a small through hole provided above the square hole; the head of the connecting bolt 6 is arranged in the square hole, passes out of the support plate 2 at the upper end and is fixed by a nut; a positioning guide rail 11 is provided at the bottom of the base 1. The square hole of the stepped through hole 10 can place the head of the connecting bolt 6 and prevent the head of the connecting bolt 6 from rotating. The side length of the square hole in the stepped through hole 10 is not greater than the maximum diameter of the head of the connecting bolt 6, so as to achieve the anti-rotation effect. The positioning guide rail 11 is provided at the bottom of the base 1, and the length of the positioning guide rail 11 is the same as the length direction of the sliding groove. Corresponding positioning grooves are provided on the bottom plate of the scraper conveyor or on the ground or the bottom plate under the power unit motor. The connection between the base 1 and the scraper conveyor is realized through the cooperation of the positioning guide rail 11 and the positioning groove. Because the pressure of the power unit motor is large and the self-weight of the adjustable auxiliary support is also large, the adjustable auxiliary support will not move under the working state, and the cooperation of the positioning guide rail and the positioning groove is sufficient; there is no need for a device for fixing the position. Of course, a fixing device can also be provided. For example, vertical plates are respectively provided on the left and right sides at both ends of the bottom plate corresponding to the positioning groove, and tightening screws are respectively provided on the vertical plates. After adjusting the position of the base 1 in the positioning groove, the left and right ends of the base are tightened by the two tightening screws.
[0025] During specific implementation: Select the number of layers of the adjusting cushion plate 3 according to the required supporting height, and connect and fix the base 1, the adjusting support, and the support plate 2 through the connecting bolts 6. Connect the two support blocks 4 through the double-headed screw rod 5, and adjust the maximum distance between the two support blocks 4 according to the size of the motor of the required model. Arrange the adjusted adjustable auxiliary support under the motor of the power unit. When it is necessary to adjust the height or the distance between the support blocks 4, loosen the double-headed screw rod 5 or the connecting screw rod for adjustment. The overall adjustable auxiliary support is under the power unit and can adapt to the motor support under various models. The standardization degree is improved. Other adjustable auxiliary support devices used on the scraper conveyor, as long as they have the same principle as this solution, are within the scope of protection of this patent.
[0026] The technical features of the above-described embodiments can be combined arbitrarily. As long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification. Without departing from the overall concept of the present invention, according to the technical solution of the present invention and equivalent replacements or changes made, as well as several changes and improvements made, it should also be regarded as the protection scope of the present invention.
