Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of equipment level correction, in particular to an equipment footing leveling device. BACKGROUND

[0002] In most cases, in order to ensure that the equipment can be successfully installed and reach the expected technical standards, the specific mechanical equipment needs to carry out ground excavation work at the corresponding position of the workshop before formal installation. This process involves digging the ground to a certain depth and rebuilding a solid foundation that meets the equipment installation requirements on this basis. The main purpose is to ensure that the equipment can meet a series of technical requirements after installation, such as the levelness of the equipment. By ensuring the levelness of the equipment, the stability and reliability of the equipment during operation can be further guaranteed.

[0003] This method of ground excavation and foundation reconstruction is not suitable for all cases. It is mainly suitable for ground workshops, that is, those workshops where equipment can be directly installed on the ground. Although this method can ensure the stable operation of the equipment, it also has some obvious disadvantages. First of all, since it involves ground excavation, foundation construction, and subsequent ground repair work, the cost is relatively high. Secondly, this method is time-consuming and labor-intensive, requiring a long construction period, which negatively affects the normal production activities of the workshop.

[0004] For workshops whose floor can bear the weight of the equipment and have other important building facilities below, the traditional foundation construction method is obviously not suitable. In this case, the equipment cannot be excavated and the foundation cannot be reconstructed, but can be placed directly on the ground. In order to ensure the levelness of the equipment, engineers will use iron sheets of different thicknesses under the feet of the equipment to adjust. Each foot usually needs to use multiple iron sheets of different thicknesses to raise the height to ensure the overall levelness of the equipment.

[0005] However, even in such cases, the level adjustment of the equipment is not a one-time job. Over time, the equipment may change in level during operation due to various factors. Therefore, engineers must regularly check and adjust the level of the equipment to ensure that the equipment maintains the correct posture. This ongoing maintenance work is crucial to ensure long-term stable operation of the equipment. Currently, the method for adjusting the equipment foot is usually to pad different thicknesses of metal sheets under the equipment foot. When adjusting the level of the equipment, all equipment feet need to be adjusted with shims. Each adjustment requires the use of lifting machinery to lift and lower the equipment, test, and then repeat the above steps until the technical requirements are met. In addition, the thickness of the shims is not the same, resulting in non-linear height adjustment, and theoretically, the optimal level cannot be achieved. On the other hand, repeatedly raising and lowering the equipment is not safe, is easy to cause local damage to the equipment, and the operation process is too cumbersome, time-consuming and labor-intensive.

[0034] In order to reduce the overall weight while ensuring the strength of the device, the shank of the foot screw 4 is in a hollow columnar structure, and the upper end part is closed by a baffle 9 and a fixing screw 10.

[0035] Please refer to Figures 1 to 3 In the embodiment, the foot nut 5 adopts a hollow variable-diameter cylindrical structure, the central hole face is provided with an internal thread matched with the external thread of the foot screw 4, at least one adjusting hole A for inserting a handle is radially arranged on the large-diameter section of the foot nut 5, and the small-diameter section of the foot nut 5 is nested in the inner ring of the thrust bearing 7. A plurality of fixing holes for inserting the fixing screw 6 are radially arranged on the large-diameter section of the foot nut 5.

[0036] In a specific application scenario, in order to avoid the displacement of the foot upper cover during the operation of the device, a non-through limiting groove is excavated on the lower end surface of the foot upper cover 8, and the outer ring of the thrust bearing 7 is embedded in the limiting groove. As a preferred, the foot upper cover 8 and the device foot 14 are connected and fixed by a bolt assembly, and the bolt assembly simultaneously serves as an auxiliary support between the foot upper cover 8 and the foot base 1. Specifically, the bolt assembly includes a fixed screw 11, which penetrates the device foot and the foot upper cover in turn, and the lower end is inserted into the corresponding positioning groove on the foot base. An upper washer 12 and an upper fixed nut 13 are arranged on the fixed screw 11 on the upper segment of the device foot 14, and a lower washer 3 and a lower fixed nut 2 are arranged on the fixed screw 11 on the lower segment of the foot upper cover 8.
