[0002] During the installation of mechanical equipment, pairs of wedge shims are typically used for leveling and aligning. However, the angled design of these shims makes them prone to slippage under heavy loads, leading to decreased equipment stability. Therefore, for equipment subjected to heavy loads or continuous vibration, flat shims are often used for adjustment. However, a set of shims should generally not contain more than five pieces, and the thickness of the shims should not be less than 2mm. This makes adjusting the flat shims more difficult, and the equipment accuracy cannot be guaranteed. Utility Model Content

[0020] Various embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. In the various drawings, the same elements are indicated by the same or similar reference numerals. For clarity, the various parts in the drawings are not drawn to scale.

[0021] This utility model provides a progressively adjusting inclined shim, see [link / reference]. Figures 1 to 2The progressive adjustment shim includes a shim body 1; wherein the shim body 1 is a block in the shape of a right triangle or a right trapezoid; a step structure is provided on the inclined surface of the shim body 1, the step structure includes multiple steps 11 of the same size, and the ratio of the height to the width of each step 11 is consistent with the slope of the inclined surface of the shim body 1.

[0022] Specifically, the material of the inclined shim body 1 is carbon steel. During manufacturing, a set of inclined shims with a consistent slope is first processed. Then, a progressive step structure is processed on the inclined surface, with each step 11 having the same height. After the step structure is processed, grinding tools (including sandpaper, grinding discs, grinding wheels, etc.) are used to grind the step structure, removing uneven surfaces and achieving the required roughness. The precision requirements of the step structure are selected based on the precision of the equipment; a commonly used roughness grade is Ra12.5. After processing, the contact fit of the stepped structure of the set of inclined shim bodies 1 is checked to ensure it meets the requirements. The slope of the inclined surface of the inclined shim body 1 is 1:10 to 1:40. For general mechanical equipment, the slope of the inclined surface of the inclined shim body 1 is 1:10 to 1:20. For equipment with significant vibration or precision, the slope of the inclined surface of the inclined shim body 1 can be 1:40. For example, for a wedge shim with a slope of 1:20, the ratio of the height to the width of each step 11 machined on the slope is also 1:20. Preferably, the height of each step 11 is 0.5mm to 3mm. In this embodiment, the wedge shim body 1 is a block shaped like a right trapezoid.

[0023] Furthermore, a U-shaped groove 12 is formed on the inclined shim body 1. The opening of the U-shaped groove 12 faces the lower end of the inclined surface of the inclined shim body 1, and the U-shaped groove 12 penetrates the inclined surface of the inclined shim body 1 and the bottom surface opposite to the inclined surface. The width of the groove 12 is 2mm to 5mm larger than the diameter of the anchor bolt, so that the anchor bolt can pass through easily. By forming a U-shaped groove 12 on the inclined shim body 1, the anchor bolt can pass through the U-shaped groove 12 on the inclined shim body 1 during use. The U-shaped groove 12 is located in the middle of the width direction of the inclined shim body 1, so that the inclined shim can provide a uniform force on the equipment base on both sides of the anchor bolt during use.

[0024] This utility model also provides a device base fixing structure, see [link to relevant documentation] Figure 3The equipment base fixing structure includes progressive adjusting wedges as described above, as well as an equipment base 4, anchor bolts 3, and nuts 5. The lower end of the anchor bolt 3 is embedded in the equipment foundation 7, and the upper end of the anchor bolt 3 is connected to the equipment base 4 via the nuts 5. Two progressive adjusting wedges are positioned between the equipment foundation 7 and the equipment base 4, with their inclined surfaces facing each other. The equipment base 4 fixing structure also includes a flat shim 2, which is positioned between the equipment foundation 7 and the two progressive adjusting wedges.

[0025] Specifically, the lower end of the anchor bolt 3 has a hook-shaped structure so that when the anchor bolt 3 is pre-embedded in the equipment foundation 7, the hook-shaped structure is embedded in the concrete of the equipment foundation 7 to form a mechanical engagement, which can enhance the anchoring performance of the anchor bolt 3 in the equipment foundation 7 and ensure that it is not easily pulled out when subjected to tensile, vibration or impact loads.

[0026] The upper end of the anchor bolt 3 is provided with an external thread that matches the nut 5. The upper end of the anchor bolt 3 passes through the bolt hole on the equipment base 4 and is threadedly connected to the nut 5. The external thread at the upper end of the anchor bolt 3 can be machined by a thread rolling machine to ensure that it has high mechanical strength.

[0027] See Figure 3 A flat washer 6 is also provided between the nut 5 and the upper surface of the equipment base 4. By setting the flat washer 6, the contact area between the nut 5 and the equipment base 4 can be increased, and the pressure per unit area can be reduced, thereby protecting the surface of the equipment base 4 from damage. At the same time, the flat washer 6 can also fill any slight unevenness or roughness on the upper surface of the equipment base 4, so that the pressure is evenly transmitted and the nut 5 can be tightened to achieve the designed preload. A spring washer can also be set between the nut 5 and the flat washer 6 to prevent loosening, or 2 to 3 nuts 5 can be screwed on the upper end of the anchor bolt 3 to prevent the nuts 5 from loosening due to equipment vibration.

[0028] When installing equipment using the progressively adjustable inclined shims provided by this utility model, in conjunction with the flat shims 2, the equipment base 4 is raised or lowered using jacks or lifting tools based on the measured elevation. The adjustment value can be determined according to the number of steps on the inclined shims or by measuring instruments. For example, if the height of the step 11 on the inclined shim body 1 is 1mm, and the elevation is 3mm lower, the inclined shims only need to be raised by 3 steps to meet the requirement. Alternatively, the adjustment value can be directly read using measuring instruments.

[0029] This progressive adjusting wedge shim can be configured with step heights of 0.5mm, 1mm, 2mm, etc., based on the allowable deviation of equipment elevation. Each step has a fixed dimension during equipment adjustment, allowing for direct determination of the adjustment level based on the number of steps. This progressive adjusting wedge shim combines the advantages of flat and wedge shims, ensuring planar contact rather than inclined contact, avoiding the risk of slippage on inclined surfaces, resulting in more reasonable force distribution, stronger stability, and more reliable safety. During equipment installation and adjustment, because this progressive wedge shim set has many progressive steps, each with the same height, it can also be used as a temporary adjustment tool. For example, during shim-less grouting construction, it facilitates fixed-length adjustments to equipment elevation. A single wedge shim can also directly contact the equipment base plate to bear force, assisting in the adjustment of other shims. This progressive adjusting wedge shim can be widely used in equipment adjustment in industries such as construction, steel structures, fire protection, metallurgy, and machinery.

[0030] In summary, the progressive adjustment wedge shim and the equipment base fixing structure including the wedge shim provided by this utility model, by setting a step structure including multiple steps on the inclined surface of the wedge shim body, can ensure that the contact surfaces of two oppositely arranged wedge shims are in planar contact rather than inclined contact during use, avoiding the risk of slippage, making adjustment more convenient during equipment installation, and ensuring more reasonable force distribution, thereby improving the stability and safety of the equipment after installation.
