Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of diesel engines, and particularly relates to an adjusting bolt for equipment displacement adjustment. Background Art
[0002] With the development of the marine economy, the volume of logistics worldwide has increased sharply, ships are getting larger and larger, and shipping has become the main mode of logistics. During the manufacturing stage of the ship generator set equipment, the alignment adjustment between the diesel engine and the generator needs to be carried out, and after entering the cabin, the alignment adjustment also needs to be carried out. After the alignment meets the requirements, the generator installation fasteners are fixed according to the specified torque. To ensure the accurate alignment of the ship generator set, the installation adjustment of the generator must be carried out. Since the generator is large in volume and heavy in weight, and due to the space problem of the ship engine room, it is impossible to use a crane to lift the generator for alignment adjustment work. Currently, a special tooling for adjustment is designed on the generator installation base to carry out the alignment adjustment of the unit. The adjustment tooling bracket is fixed on the generator installation base with threads, and the position of the generator is adjusted in the horizontal direction (front, back, left, right) and the vertical direction by using the method of rotating and jacking bolts.
[0003] The overall composition of the diesel engine generator set consists of a diesel engine, a generator and a common base. When the current generator is aligned and adjusted with the unit, the tooling adopts Figure 5 the layout method. Although it can achieve the purpose of aligning and adjusting the generator 3 with the diesel engine, there are still the following deficiencies: 1) After installing the power generation 3 adjustment tooling (bracket 4 + bolt) on the common base 2, the bolt is a full-thread bolt (usually using the national standard standard part GB / T5783). During the process of rotating the bolt, the thread at the bolt head is prone to deformation; at the same time, the head of the full-thread bolt is a plane, which will seriously damage the surface state of the equipment when jacking up the equipment (due to the flatness of the non-working and non-installation area plane on the equipment surface). Because the bolt head is a plane, the force on the thread head is uneven during the jacking process, resulting in the phenomenon that the bolt thread and the bracket 4 thread are deflected or even stuck, affecting the use efficiency; 2) If the bolt needs to be replaced later, the bolt cannot be taken out of the bracket 4 (due to thread deformation and sticking), and only destructive disassembly or re-making of a new bracket can be carried out, and the replacement cost is relatively high; 3) During the jacking process, the bolt head is a plane and the equipment surface is a plane. When adjusting, the personnel need to use a lot of force (because the contact surface is too large and the pressure generated by the same force is small), and the work efficiency is not high. Therefore, in view of the above problems, it is necessary to make improvements. Content of the Utility Model
[0004] Technical problems solved by the utility model: Provide an adjusting bolt for equipment displacement adjustment. By optimizing the structure of the body itself, a trimming reserved section and a wear-reducing head are designed on the basis of a traditional bolt, effectively solving the problems that the traditional bolt is stuck with the bracket due to head wear and deformation and the serious damage to the equipment surface. Ensure reliable connection and smooth rotation between the body and the bracket, improve the service life of the bracket and the body, with simple structure, reasonable design, and convenient replacement of the body, which can effectively improve the use efficiency and service life of the generator installation and positioning tooling, and reduce the degree of equipment surface damage.

The lower end of the trimming reserved section is provided with a wear-reducing head for contacting the outer surface of the equipment and having an arc surface.
[0006] Among them, the wear-reducing head is a spherical arc surface, a semi-circular arc surface, or an inverted conical arc surface with a spherical structure at the tip.
[0007] Further, the length dimension of the trimming reserved section is 5 - 10 mm, and the radius of the wear-reducing head is equal to 1 / 2 of the minor diameter of the thread of the screw rod section.

[0009] Further, the bracket has an L-shaped structure, and the horizontal plate at the lower end of the bracket is fixed to the common base through a connecting bolt, while the screw rod section of the body is threadedly connected to the vertical plate of the bracket.

[0019] The following will combine the Figures 1-4 in the embodiments of the present utility model to clearly and completely describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0021] In this article, the terms "comprising", "including" or any other variants thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising one..." does not exclude the presence of additional identical elements in the process, method, article or device comprising said element.
[0022] The position-adjusting bolt for equipment displacement adjustment, such as Figures 1-4 shown, includes a body 1 threadedly connected to a bracket 4. The body 1 includes a hexagonal head section 1-1, a screw rod section 1-2, a trimming reserve section 1-3 and an anti-friction head 1-4 of an integral structure. The upper end of the screw rod section 1-2 is integrally and transitionally connected to the middle of the bottom surface of the hexagonal head section 1-1, and the lower end of the screw rod section 1-2 is integrally and transitionally connected to the upper end of the trimming reserve section 1-3. The lower end of the trimming reserve section 1-3 is provided with an anti-friction head 1-4 for contacting the outer surface of the equipment and having an arc surface. In the above structure, by optimizing the structure of the body 1 itself, a trimming reserve section is designed on the basis of a traditional bolt to provide a trimming allowance for the trimming after the wear of the anti-friction head 1-4, thereby realizing the reuse of the body 1 and greatly increasing the service life of the body 1. By designing the anti-friction head 1-4 on the basis of a traditional bolt, the contact area between the arc surface part and the outer surface of the equipment is small when lifting the equipment. Without generating an axial component force, abnormal thread extrusion deformation will not occur, and the pressure generated when lifting the equipment is large, reducing the damage to the equipment surface to the lowest level. At the same time, the quality of the thread of the screw rod section 1-2 is ensured, ensuring the smooth rotation operation of the body 1 on the bracket 4. It effectively solves the problems of the traditional bolt being stuck with the bracket due to the wear and deformation of the head and the disadvantage of serious damage to the equipment surface.
[0023] The specific shape of the anti-friction head 1-4 is as follows: The anti-friction head 1-4 is a spherical arc surface or a semi-circular arc surface or an inverted conical arc surface with a spherical structure at the tip, and the processing type of the anti-friction head 1-4 can be determined according to the requirements of the use site.
[0024] Specifically, the length dimension of the trimming reserve section 1-3 is 5-10 mm, which is convenient for the tool to enter and retreat when processing the spherical anti-friction head 1-4. Usually, a national standard bolt is selected for supplementary processing of the spherical arc surface, and the radius of the anti-friction head 1-4 is equal to 1 / 2 of the minor diameter of the thread of the screw rod section 1-2. Specifically, the diameter of the trimming reserve section 1-3 is not greater than the diameter of the screw rod section 1-2, ensuring that the trimming reserve section 1-3 can smoothly pass through the threaded hole on the vertical plate at the upper end of the bracket 4 and providing a trimming allowance for the trimming of the worn anti-friction head 1-4, thereby increasing the service life of the body 1.
[0025] Among them, such as Figures 2-4As shown, the bracket 4 has an L-shaped structure, and the horizontal plate at the lower end of the bracket 4 is fixed to the common base 2 through connecting bolts, while the screw section 1-2 of the body 1 is threadedly connected to the vertical plate of the bracket 4.
[0026] This technical solution has a simple structure, reasonable design, convenient replacement of the body, improves the service life of the bracket and the body, improves the efficiency and accuracy of equipment position adjustment, can effectively improve the service efficiency and life of the generator installation and positioning tooling, and reduces the degree of surface damage of the equipment.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model.
