Description

Technical Field

[0001] This utility model relates to the field of calibration device technology, and in particular to a calibration device for a generator set. Background Technology

[0002] A unit refers to a group of machines, such as a compressor unit, a refrigeration unit, a generator set, etc. It is generally a system consisting of a prime mover driving the compressor and auxiliary machines.

[0003] In existing technologies, traditional medium-sized generator sets are often directly fixed to a concrete pier that has been poured in one go. The generator set legs are connected to the anchor bolts pre-embedded on the surface of the concrete pier. However, during long-term operation of the generator set, the vibrations generated often cause cracks between the generator set legs and the foundation contact surface, resulting in large vibrations during generator set operation and making it difficult to correct the vibrations. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that the vibration generated during long-term operation of the unit equipment often causes cracks between the contact surface of the unit's support legs and the foundation, resulting in large vibrations during unit operation and difficulty in correction. Therefore, this invention proposes a correction device for the unit.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a calibration device for a unit, comprising: a cast body, a base, a first shim, a second shim, and an I-beam. Multiple first and second shims are provided, and multiple sets of the first and second shims are provided. Multiple sets of the first shims are equidistantly arranged on the top of the base. Pre-embedded bolts are provided on the inner side of each set of the first shims, and the pre-embedded bolts movably penetrate the base. Multiple I-beams are provided, and the multiple I-beams are evenly arranged below the base. Multiple positioning grooves are evenly provided on the bottom of the base. Multiple sets of the second shims are respectively arranged between the multiple positioning grooves and the multiple I-beams.

[0006] Preferably, the top of the casting body is provided with a plurality of casting holes at equal intervals, and the axial distance between the plurality of casting holes is equal.

[0007] Preferably, the top of the I-beam is symmetrically fixedly connected with a positioning rod, and the positioning rod passes through the second washer.

[0008] Preferably, the top of the first gasket is symmetrically provided with limiting grooves, and the bottom of the first gasket is symmetrically provided with sliders, the sliders being matched with the limiting grooves.

[0009] Preferably, the top of the base has multiple mounting slots symmetrically arranged, and the mounting slots are matched with the slider.

[0010] Preferably, a plurality of guide blocks are equidistantly arranged at the bottom of the base, and the inner surfaces of the plurality of guide blocks are slidably connected to the outer surfaces of a plurality of pre-embedded bolts.

[0011] Preferably, a circular plate is fixedly connected to the bottom of the pre-embedded bolt, and multiple through holes are equidistantly opened at the top edge of the circular plate, with the circular plate located inside the casting hole.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, during use, a pre-reserved pouring hole is made in the top of the cast body formed by the original primary grouting of the unit equipment. When placing and calibrating the base, after determining the error of the bolt pre-embedding, secondary grouting is performed in the pouring hole to fix multiple pre-embedded bolts above the cast body. Multiple I-beams are set between the base and the cast body for support, so that the unit equipment is fixedly installed on the base and does not directly contact the top of the cast body. When the equipment has a horizontal error due to vibration in the later stage, and maintenance and calibration are required, the number of multiple sets of first shims can be adjusted in sequence according to the measurement results of the level ruler to correct the unit equipment to a horizontal state, which plays a role in facilitating calibration.

[0014] 2. In this utility model, when in use, a circular plate is connected to the bottom of the pre-embedded bolt. The circular plate can increase the fixing effect of the pre-embedded bolt. Multiple through holes are opened at equal intervals on its surface, which facilitates the rapid filling of concrete into the pouring hole during secondary pouring, making it highly practical.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-5 As shown, this utility model provides a calibration device for a unit, including: a cast-in-place body 1, a base 3, first shims 8, second shims 13, and I-beams 11. Multiple first shims 8 and second shims 13 are provided, and multiple sets of first shims 8 and second shims 13 are provided. Multiple sets of first shims 8 are equidistantly arranged on the top of the base 3. Pre-embedded bolts 4 are provided on the inner side of each set of first shims 8, and the pre-embedded bolts 4 movably pass through the base 3. Multiple I-beams 11 are provided, and multiple I-beams 11 are evenly arranged below the base 3. Multiple positioning grooves 7 are evenly provided on the bottom of the base 3. Multiple sets of second shims 13 are respectively arranged in the multiple positioning grooves 7 and the multiple positioning grooves 11. Between each I-beam 11, multiple pouring holes 2 are equidistantly opened at the top of the casting body 1. The axial distance between the multiple pouring holes 2 is equal. A positioning rod 12 is symmetrically fixedly connected to the top of the I-beam 11. The positioning rod 12 and the second shim 13 are movably connected through each other. A limiting groove 9 is symmetrically opened at the top of the first shim 8. A slider 15 is symmetrically arranged at the bottom of the first shim 8. The slider 15 and the limiting groove 9 are matched. Multiple mounting grooves 10 are symmetrically opened at the top of the base 3. The mounting grooves 10 and the slider 15 are matched. Multiple guide blocks 14 are equidistantly arranged at the bottom of the base 3. The inner surface of the multiple guide blocks 14 is slidably connected to the outer surface of the multiple pre-embedded bolts 4 respectively.

[0024] The overall effect of Embodiment 1 is as follows: Before the unit is installed, the base 3 is first placed on the concrete casting body 1, which is formed by one-time concrete pouring, so that multiple circular plates 5 are in the corresponding pouring holes 2. Multiple I-beams 11 are placed under the base 3, and the level of the base 3 is corrected using a spirit level. Multiple second shims 13 are placed between the multiple I-beams 11 and the base 3 until the top of the base 3 is nearly level. The top of the I-beams 11 is symmetrically connected to positioning rods 12, which can limit the second shims 13 above them. The bottom of the base 3 has a positioning groove 7, which further limits the second shims 13. After the top of the base 3 is corrected to a level state, when a suitable amount of concrete is injected into the multiple pouring holes 2 for secondary pouring, the exposed pre-embedded bolts 4 are adjusted up and down. The length allows multiple pre-embedded bolts 4 to be fixed on the cast body 1. After it has completely solidified, the unit equipment can be hoisted onto the base 3 and connected to the multiple pre-embedded bolts 4. When the unit equipment is connected to the pre-embedded bolts 4 for secondary correction, multiple first shims 8 can be inserted between the equipment legs and the base 3 in sequence. The first shim 8 at the bottom will slide in the corresponding two mounting slots 10 through the sliders 15 symmetrically arranged at the bottom. The first shim 8 inserted above it will be limited in the limiting slot 9 opened at the top of the first shim 8 below. When the equipment has a horizontal error due to vibration and needs to be repaired and corrected later, the number of multiple sets of first shims 8 can be adjusted in sequence according to the measurement results of the level ruler to correct the unit equipment to a horizontal state, which facilitates the correction.

[0025] Example 2: Figures 1-5 As shown, a circular plate 5 is fixedly connected to the bottom of the pre-embedded bolt 4. Multiple through holes 6 are equidistantly opened at the top edge of the circular plate 5, and the circular plate 5 is located inside the pouring hole 2.

[0026] The effect achieved by the entire embodiment 2 is that, in use, by connecting the circular plate 5 to the bottom of the pre-embedded bolt 4, the circular plate 5 can increase the fixing effect of the pre-embedded bolt 4. The multiple through holes 6 equidistantly opened on its surface facilitate the rapid filling of concrete into the pouring hole 2 during secondary pouring, which is highly practical.

[0027] Working Principle: Before installation, the base 3 is placed on the concrete pouring body 1, ensuring that multiple circular plates 5 are positioned within their corresponding pouring holes 2. Multiple I-beams 11 are placed below the base 3. A spirit level is used to correct the levelness of the base 3. Multiple second shims 13 are placed between the I-beams 11 and the base 3 until the top of the base 3 is nearly level. Positioning rods 12 are symmetrically connected to the top of the I-beams 11, limiting the position of the second shims 13 above them. Positioning grooves 7 are provided at the bottom of the base 3 to further limit the position of the second shims 13. After the top of the base 3 is leveled, a suitable amount of concrete is poured into the multiple pouring holes 2 for secondary pouring. The exposed length of the embedded bolts 4 is adjusted vertically to fix the bolts 4 onto the pouring body 1. After complete solidification, the unit can be hoisted onto the base 3. It can be connected to multiple pre-embedded bolts 4. When the unit equipment is connected to the pre-embedded bolts 4 for secondary correction, multiple first shims 8 can be inserted between the equipment legs and the base 3 in sequence. The first shim 8 at the bottom will slide in the corresponding two mounting slots 10 through the sliders 15 symmetrically set at the bottom. The first shim 8 inserted above it will be limited in the limiting slot 9 opened at the top of the first shim 8 below. When the equipment has a horizontal error due to vibration and needs to be repaired and corrected later, the number of multiple sets of first shims 8 can be adjusted in sequence according to the measurement results of the level ruler to correct the unit equipment to a horizontal state, which plays a role in facilitating correction. By connecting the circular plate 5 to the bottom of the pre-embedded bolt 4, the fixing effect of the pre-embedded bolt 4 can be increased. The multiple through holes 6 opened at equal intervals on its surface facilitate the rapid filling of concrete into the pouring hole 2 during secondary pouring, which is highly practical.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
