Description

Technical Field

[0001] The utility model relates to the technical field of equipment installation, in particular to an equipment installation structure. Background Art

[0002] When the equipment is installed, the bottom surface of the adjustment shim is in contact with the foundation, and the upper surface is in contact with the bottom of the bed. Due to certain deviations in the production of the equipment foundation and poor surface flatness, the upper and lower surfaces of the adjustment shim are in poor contact with the bottom of the equipment bed and the foundation ground. Uneven force causes premature damage to the adjustment shim or affects the equipment's operating accuracy.

[0003] In addition, in the past foundation design, the foundation plane for installing the adjustment shim is usually at the same height as the zero plane in the workshop. In order to ensure that iron filings do not enter the bottom of the bed, red bricks and cement are usually used to seal between the bottom of the bed and the adjustment shim on the foundation plane. Since it is a sealing of limited space after installation, the sealing operation is difficult. There is also the risk of iron filings falling into the adjustment shim, increasing the difficulty of adjusting the adjustment shim and even damaging the adjustment shim. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the embodiments of the utility model is to provide an equipment installation structure to solve the problems of poor contact between the adjusting shim and the bottom of the equipment and the foundation ground, difficulty in sealing operation, and easy damage to the adjusting shim.

[0005] In order to achieve the above purpose, the embodiment of the utility model provides the following technical solutions:

[0006] A equipment installation structure, comprising: a sinkhole, a fixing assembly and a cover plate; the sinkhole comprises a foundation pit and a footing pit, the footing pit is located at the lower side of the foundation pit, and the cross-section of the foundation pit is larger than the cross-section of the footing pit; the fixing assembly comprises an adjusting shim, a pad and an anchor bolt, the lower side of the anchor bolt is located in the footing pit, the upper side of the anchor bolt is connected to the equipment, the pad is located at the interface between the foundation pit and the footing pit, the adjusting shim is located between the pad and the equipment, and the anchor bolt is provided with a limiting ring for pre-fitting the adjusting shim and the pad to the equipment; the cover plate is installed on the foundation pit, and the inner end of the cover plate is against the side of the equipment.

[0007] Optionally, a step is provided on the outer edge of the foundation pit, and the step is sunken to the lower side of the zero plane of the foundation.

[0025] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0026] For the problem of poor contact between the upper and lower surfaces of the adjusting shims and the bottom of the equipment bed and the foundation ground, the common remedial measure is to add a frame to raise the grouting material above the ground level during the second grouting after the equipment is roughly adjusted; or to ensure that the adjusting shims are in contact with the ground, and add a spherical contact pad to the upper plane of the adjusting shims to compensate for the insufficient contact between the bottom of the bed and the adjusting shims.

[0027] Of the above two methods, the first one increases the difficulty of grouting operation and is labor-intensive and time-consuming; the second one increases the cost of equipment installation and the height of the equipment bed relative to the ground by adding accessories. The stability of the equipment is poor compared to the method of directly adjusting the adjustment shims.

[0028] To solve the problem of iron filings entering the bottom of the bed, red bricks and cement are usually used to seal the space between the bottom of the bed and the adjustment shim on the base plane. However, since it is a sealing operation in a limited space after installation, the sealing operation is difficult. In addition, there is a risk that iron filings will fall into the adjustment shim, increasing the difficulty of adjusting the adjustment shim and even damaging the adjustment shim.

[0029] In order to solve the above technical problems, the utility model proposes a device 8 installation structure, such as Figure 1As shown, it includes: a sinkhole, a fixing assembly and a cover plate 4; the sinkhole includes a foundation pit 1 and a footing pit 2, the footing pit 2 is located at the lower side of the foundation pit 1, and the cross section of the foundation pit 1 is larger than the cross section of the footing pit 2 (as shown in FIG. Figure 3 The cross section refers to the projection surface viewed from top to bottom.

[0030] The fixing assembly includes an adjusting shim 6, a pad 5 and an anchor bolt 7. The sinking depth of the foundation pit 1 is slightly greater than the thickness of the adjusting shim 6 and the pad 5. The lower side of the anchor bolt 7 is located in the anchor pit 2, and the upper side of the anchor bolt 7 is connected to the equipment 8. The pad 5 is located at the interface between the foundation pit 1 and the anchor pit 2, and the adjusting shim 6 is located between the pad 5 and the equipment 8. The anchor bolt 7 is also provided with a limiting ring 10 for pre-attaching the adjusting shim 6 and the pad 5 to the equipment 8. The limiting ring 10 can be a nut, and the limiting ring 10 is threadedly connected to the anchor bolt 7; or, the limiting ring 10 is a retaining ring or round steel welded on the anchor bolt 7. The cover plate 4 is installed on the foundation pit 1, and the inner end of the cover plate 4 (i.e. Figure 1 The right end in the middle is against the side of the device 8, and the adjustment shim 6 is completely covered on the lower side.

[0031] During installation, first use the limiting ring 10 and the anchor bolt 7 to clamp the pad 5 and the adjustment shim 6 on the bottom surface of the equipment 8, place the equipment 8 for installing and fixing the components at the corresponding anchor holes, place 4 to 6 adjustment shims on both sides of the bed length where no anchor holes are set, adjust the position and posture of the machine tool to the installation requirements, ensure that the lower plane of the pad 5 is slightly lower than the interface, pour grout into the anchor pit 2, fine-tune the equipment 8 to the accuracy requirements by adjusting the shim 6, and cover the cover plate 4 on the foundation pit 1.

[0032] In the installation structure of the equipment 8 of the utility model, the upper plane of the adjusting shim 6 is ensured to be in full contact with the bottom surface of the bed during installation, and the lower plane is in full contact with the pad 5, ensuring the parallelism between the pad 5 and the bottom surface of the bed. After the anchor bolts 7 are installed, the secondary grouting can be directly performed to ensure the contact area between the adjusting shim 6 and the bottom surface of the bed and the foundation ground, greatly improving the service life of the adjusting shim 6 and the stability of the operation of the equipment 8. The subsequent measures of increasing the service life of the adjusting shim 6 and the stability of the equipment 8 by adding accessories or adding a frame during the secondary grouting are improved, the difficulty of the installation operation is greatly reduced, and the labor and material costs of the installation of the equipment 8 are reduced.

[0033] By sinking the foundation plane for installing the equipment 8, the adjusting shim 6 is placed in the foundation pit 1, covered with the cover plate 4, and the inner side of the cover plate 4 directly abuts against the side of the equipment 8, so that iron filings are prevented from entering the bottom of the bed of the equipment 8 and will not fall into the adjusting shim 6, thereby ensuring the normal use of the adjusting shim 6. At the same time, the adjusting shim 6 is all at the bottom of the cover plate 4, and the overall appearance of the equipment 8 is beautiful.

[0034] like Figure 1 As shown, the outer edge of the foundation pit 1 (i.e. Figure 1 The left side of the step is provided with a step, the step is sunken to the lower side of the zero plane of the foundation, the outer contour of the cover plate 4 is installed on the step, and the upper plane of the cover plate 4 is flush with the zero plane of the foundation. Further, an edge angle steel 3 is provided at the step position, the cross section of the edge angle steel 3 is a right angle, the edge angle steel 3 is installed on the edge of the step, the cover plate 4 is installed on the edge angle steel 3, and the cover plate 4 can be a patterned plate. The inner side of the edge angle steel 3 has anchor bars, and the anchor bars are inserted into the ground foundation.

[0035] A foundation pit 1 is formed by sinking the foundation plane for installing the equipment 8, the sinking depth is slightly greater than the thickness of the adjusting shim 6 + the pad 5, and the edge protection angle steel 3 is added. The upper plane of the edge protection angle steel 3 is 4mm lower than the horizontal plane of the workshop (it is flush with the ground after placing the patterned plate). After the equipment 8 is installed, the patterned plate is installed on the upper part of the edge protection angle steel 3 and the adjusting shim 6 to prevent iron filings from entering the bottom of the bed. At the same time, the adjusting shims 6 are all under the patterned plate, and the overall appearance of the equipment 8 is beautiful.

[0036] like Figure 1 As shown, the top of the footing pit 2 has an expanded pit 9, and the cross section of the expanded pit 9 is larger than the cross section of the adjustment pad 6. A large opening structure is adopted at the top of the footing pit 2, such as Figure 2 As shown, it is the cross section of the foot pit 2 viewed from top to bottom, H×(A+B) is the opening size, which is larger than the projection size of the adjustment pad 6 and the pad 5, so as to facilitate the position adjustment of the pad 6. The depth of the expanded pit 9 can be made as 30mm-40mm, which serves as the sinking space for the adjustment pad 6 and the pad 5. The left side (A size indication) is the adjustable screw of the adjustment pad 6, so as to facilitate the grouting after the adjustment is completed.

[0037] At least part of the lower side of the pad 5 is located in the flaring pit 9, and at least part of the upper side of the pad 5 is located in the foundation pit 1. That is, the bottom of the pad 5 is sunk into the flaring pit 9, and the upper part is higher than the flaring pit 9, ensuring that the lower plane of the pad 5 is completely in contact with the grouting material after grouting; the upper plane of the pad 5 is higher than the upper plane of the flaring pit 9, ensuring that the adjustment shim 6 can be normally withdrawn after the secondary grouting, which is convenient for replacing the damaged adjustment shim 6 during use.

[0038] The expansion pit 9 and the anchor pit 2 are transitioned by a slope, and the slope is located on the side of the anchor pit 2 away from the equipment 8, and the slope and the side wall of the anchor pit 2 have a set angle. The slope forms a grouting port to facilitate grouting. Among them, the angle between the slope and the side wall of the anchor pit 2 can be 45°.

[0039] Construction process:

[0040] Add a limiting ring 10 at the appropriate position of the anchor bolt 7, install the pad 5 and the adjusting shim 6 on the anchor bolt 7 in sequence, install the anchor bolt 7 with the pad 5 and the adjusting shim 6 at the light hole of the machine tool anchor, install the nut onto the above-mentioned anchor bolt 7 and tighten it.

[0041] Install the anchor bolts 7 of the above-mentioned installation pads 5 and adjustment pads 6 in the machine tool anchor holes in sequence, and place the foundation equipment 8 for installing the above-mentioned assembled anchor bolts 7 in the corresponding anchor holes of the foundation. Place 4 to 6 adjustment pads on both sides of the bed length where there are no anchor holes, adjust the position and posture of the machine tool to the installation requirements, and ensure that the lower plane of the pad 5 is slightly lower than the bottom surface of the foundation pit 1 (usually 1 / 3 of the thickness of the pad 5).

[0042] The grouting opening is grouted until the top surface of the expanded pit 9 is flush. After it is stabilized, the machine tool is fine-tuned to the accuracy requirement by adjusting the shim 6, and the cover plate 4 is covered on the foundation pit 1.

[0043] Because the adjustment shim ensures that its upper plane is in full contact with the bottom surface of the bed and the lower plane is in full contact with the pad during installation, the parallelism between the pad and the bottom surface of the bed is ensured, the service life of the adjustment shim and the stability of the equipment are improved, and the problem of poor contact between the adjustment shim and the ground and the bed is improved. Avoid adding a frame to raise the grouting material above the ground during secondary grouting, ensure good contact between the adjustment shim and the ground, and reduce the difficulty and cost of grouting operations. Avoid adding a spherical contact pad to the adjustment shim to compensate for the insufficient contact between the bottom surface of the bed and the adjustment shim, reduce the use of adjustment shim accessories, and improve the stability of the equipment. At the same time, it is convenient to replace damaged adjustment shims during use.

[0044] The utility model has the following technical effects:

[0045] 1. When the anchor bolts are placed in the anchor holes, they have been installed on the machine tool, which avoids the positioning and placement of a single anchor bolt, reduces the difficulty of operation, and avoids the risk of positioning error when the anchor bolts are placed alone.

[0046] 2. Anchor bolts, pads, and adjustment pads are directly installed and fixed on the bed. By adding pads, the deviation of the height of the adjustment pads is solved to ensure that the upper surface of the adjustment pads is flush. After grouting, the equipment can be fine-tuned directly based on the existing installation status.

[0047] 3. The bottom of the pad is located below the grouting plane to ensure full contact between the pad and the foundation. At the same time, the upper plane of the pad is located above the grouting plane to ensure that all the adjustment pads are located above the foundation plane, which is convenient for disassembly and replacement of the adjustment pads.

[0048] 4. The anchor bolts, pads and adjustment shims have been firmly installed on the bed, ensuring good contact between the upper surface of the adjustment shim and the bed, and good contact between the upper surface of the adjustment shim and the pad, ensuring stable precision and good retention of the machine tool after installation.

[0049] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
