Description

Technical Field

[0001] The present invention relates to the technical field of thermal power civil engineering, and in particular to a generator anchor bolt and an embedded component mounting frame. Background Art

[0002] Anchor bolts are a crucial foundational connector, commonly used to securely fasten heavy machinery to the ground or underlying structures. They are typically embedded in concrete foundations to ensure the equipment remains stable during operation and prevents movement or tilting due to vibration or external forces. The design and material selection of anchor bolts typically take into account the weight, type, and operating environment of the equipment. Anchor bolts are widely used in the foundations of various industrial equipment, such as generators, excavators, compressors, and wind turbines, enhancing their operational safety and reliability. Regular inspection and maintenance are also crucial to ensure the anchor bolts are in good condition, thereby preventing equipment failure or safety hazards caused by loosening.

[0003] Existing generator anchor bolts generally have a threaded portion, a connecting rod, and a bent portion. The threaded portion is usually located at one end of the bolt for mating with a nut. For anchor bolts, their ends may be designed into special shapes, such as hooks, rings, or other shapes, to facilitate connection with the foundation anchor or anchor plate.

[0004] However, in actual use, the generator vibrates greatly, and the anchor bolts will exert force on the concrete due to the vibration. The concrete is easily broken due to long-term force and the contact part with the anchor bolts is prone to breakage, resulting in the reduction of the tightness between the bolts and the concrete, loosening, and easy to be pulled out. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art that the anchor bolts will exert force on the concrete due to vibration, which will easily break the concrete, causing the bolts to loosen and be easily pulled out, and to propose a generator anchor bolt and embedded parts mounting bracket.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A generator anchor bolt is designed, comprising a connecting column, a mounting sleeve provided on the connecting column, a plurality of protrusions provided on the mounting sleeve, a connecting tube provided on the outer sleeve of the connecting column, a through slot provided on the connecting tube for cooperating with the protrusions, the protrusions being rotatably connected to the mounting sleeve, and the protrusions being movably plugged into the through slots;

[0008] The connecting column consists of a screw portion and a bolt portion. The screw portion is threadedly connected to the mounting sleeve. A guide portion is fixedly provided on the mounting sleeve. A guide rail that matches the guide portion is fixedly provided on the inner wall of the connecting pipe.

[0009] Furthermore, a mounting groove is provided on the mounting sleeve, the protrusion is rotatably connected to the mounting groove, and a torsion spring is provided between the protrusion and the mounting groove.

[0010] Furthermore, a positioning column is fixedly provided in the through groove, and the positioning column is provided between the protruding portion and the mounting sleeve, so that an angle is formed between the protruding portion and the mounting sleeve.

[0011] Furthermore, a positioning groove is provided on the screw portion, and a positioning component that matches the positioning groove is provided on the connecting pipe.

[0012] Furthermore, the positioning assembly includes an arc-shaped plate and a supporting structure, and the arc-shaped plate is engaged with the positioning groove.

[0013] Furthermore, the support structure includes an insertion rod provided on the connecting pipe, one end of the insertion rod is rotatably connected to the arc-shaped plate, and the insertion rod is movably plugged into the connecting pipe.

[0014] Furthermore, the support structure also includes a sleeve threadedly connected to the connecting pipe, the sleeve is provided with a socket, a spring is provided in the socket, the insertion rod is movably connected to the socket and abuts against the spring, one end of the sleeve passes through the connecting pipe and is provided with a polygonal part that cooperates with a wrench.

[0015] Furthermore, a gear is fixedly provided on the positioning groove, and a plug-in portion that matches the gear is fixedly provided on the arc-shaped plate.

[0016] Furthermore, the gear teeth are of a right-angled trapezoidal structure. When the gear rotates clockwise, the plug-in portion of the arc plate contacts the oblique side of the gear teeth. When the gear rotates reversely, the plug-in portion contacts the right-angled side of the gear teeth.

[0017] The present invention also proposes a generator embedded parts mounting bracket, including the above-mentioned generator anchor bolts, and also includes a mounting plate, the mounting plate is fixedly connected to at least one connecting pipe, a threaded column is fixedly provided on the mounting plate, and the mounting bracket also includes a base plate arranged at the lower end of the connecting pipe.

[0018] The generator anchor bolt and embedded parts mounting bracket proposed in the present invention have the following beneficial effects:

[0019] In the present invention, a plurality of protrusions are provided on the mounting sleeve. When the protrusions are opened, an umbrella-shaped structure is formed, thereby increasing the contact area between the anchor bolt and the concrete and evenly distributing the load of the anchor bolt into the concrete. This increases the contact area between the anchor bolt and the concrete and prevents the bolt from loosening due to concrete crushing.

[0020] Secondly, in the present invention, when the anchor bolt is not in use, the torsion spring drives the protrusion to retract into the installation groove, thereby reducing the space occupied by the anchor bolt and facilitating transportation and storage. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figure 1-6 A generator anchor bolt includes a connecting column 1, a mounting sleeve 2 is provided on the connecting column 1, a plurality of protrusions 3 are provided on the mounting sleeve 2, a connecting tube 4 is provided on the outer sleeve of the connecting column 1, a through slot 41 is provided on the connecting tube 4 to match the protrusion 3, the protrusion 3 is rotatably connected to the mounting sleeve 2, and the protrusion 3 is movably plugged into the through slot 41;

[0030] The connecting column 1 consists of a screw portion 11 and a bolt portion 12 . The screw portion 11 is threadedly connected to the mounting sleeve 2 . A guide portion 13 is fixedly provided on the mounting sleeve 2 . A guide rail 14 that matches the guide portion 13 is fixedly provided on the inner wall of the connecting pipe 4 .

[0031] In the present invention, a plurality of protrusions 3 are provided on the mounting sleeve 2. When the protrusions 3 are opened, an umbrella-shaped structure is formed, which increases the contact area between the anchor bolts and the concrete, and evenly distributes the load of the anchor bolts into the concrete, thereby increasing the contact area between the anchor bolts and the concrete and preventing the bolts from loosening due to concrete breakage.

[0032] Furthermore, in this embodiment, a mounting groove 21 is provided on the mounting sleeve 2, the protrusion 3 is rotatably connected to the mounting groove 21, and a torsion spring 22 is provided between the protrusion 3 and the mounting groove 21. The torsion spring 22 drives the protrusion 3 to rotate and retract it into the mounting groove 21, thereby reducing the space occupied by the anchor bolts and facilitating transportation and storage.

[0033] In this embodiment, a positioning column 411 is fixedly provided in the through groove 41. The positioning column 411 is arranged between the protrusion 3 and the mounting sleeve 2, so that an angle is formed between the protrusion 3 and the mounting sleeve 2. The connecting column 1 is rotated to drive the mounting sleeve 2 to move, and the protrusion 3 abuts against the positioning column 411, so that the angle formed between the protrusion 3 and the mounting sleeve 2 increases, and the protrusion 3 is opened to form an umbrella-shaped structure.

[0034] Furthermore, in this embodiment, a positioning groove 111 is provided on the screw portion 11, and a positioning component 5 that cooperates with the positioning groove 111 is provided on the connecting tube 4. By setting the positioning component 5 to cooperate with the positioning groove 111, the screw portion 11 is threadedly connected to the mounting sleeve 2, thereby preventing the rotating connecting column 1 from moving up and down.

[0035] In this embodiment, the positioning assembly 5 includes an arc plate 51 and a support structure 52. The arc plate 51 is engaged with the positioning groove 111. When the connecting column 1 rotates, the arc plate 51 limits the position of the connecting column 1 to prevent the connecting column 1 from moving during rotation.

[0036] It should be noted that, in this embodiment, the support structure 52 includes an insertion rod 521 arranged on the connecting tube 4, one end of the insertion rod 521 is rotatably connected to the arc plate 51, and the insertion rod 521 is movably plugged into the connecting tube 4, and the position of the arc plate 51 is controlled by controlling the position of the insertion rod 521.

[0037] In this embodiment, the support structure 52 also includes a sleeve 522 threadedly connected to the connecting pipe 4. A socket is provided on the sleeve 522, and a spring 523 is provided in the socket. The insertion rod 521 is movably connected to the socket and abuts against the spring 523. One end of the sleeve 522 passes through the connecting pipe 4 and is provided with a polygonal part that cooperates with the wrench. Its position is controlled by rotating the sleeve 522. When the sleeve 522 abuts against the connecting pipe 4, and the connecting pipe 4 drives the arc plate 51 to abut against the positioning groove 111, it plays a role in fixing the position of the connecting column 1, preventing the anchor bolt from being accidentally touched, causing the protrusion 3 to be stretched out and occupy space, and at the same time, it can prevent the anchor bolt from being accidentally touched when pouring concrete, causing the protrusion 3 to retract into the installation groove 21.

[0038] In addition, in this embodiment, a gear 524 is fixedly provided on the positioning groove 111, and a plug-in portion that cooperates with the gear 524 is fixedly provided on the arc plate 51. Through the plug-in portion cooperating with the gear 524, when the connecting column 1 is rotated, the gear 524 abuts the plug-in portion, so that the arc plate 51 is forced to move backward to squeeze the spring 523, thereby forming a damping structure.

[0039] In this embodiment, the gear teeth of the gear 524 are of a right-angled trapezoidal structure. When the gear 524 rotates clockwise, the plug-in portion of the arc plate 51 contacts the oblique side of the gear teeth. When the gear 524 rotates reversely, the plug-in portion contacts the right-angled side of the gear teeth, so that the connecting column 1 can only rotate in one direction, thereby ensuring that the protrusion 3 will not retract after being propped up.

[0040] Working method: When working, the connecting column 1 is rotated to drive the installation sleeve 2 to move, and the protrusion 3 abuts against the positioning column 411, so that the angle formed between the protrusion 3 and the installation sleeve 2 increases, and the protrusion 3 is opened to form an umbrella-shaped structure, which increases the contact area with the concrete when pouring concrete, so that the load is transferred more evenly, and the position of the connecting column 1 is restricted by the arc plate 51 to prevent the connecting column 1 from moving when rotating, and its position is controlled by rotating the sleeve 522. When the sleeve 522 abuts against the connecting pipe 4, and the connecting pipe 4 drives the arc plate 51 to abut against the positioning groove 111, it plays a role in fixing the position of the connecting column 1, preventing the anchor bolt from being accidentally touched, causing the protrusion 3 to be stretched out and occupy space.

[0041] A generator embedded parts mounting bracket includes the above-mentioned generator anchor bolts and a mounting plate 6, which is fixedly connected to at least one connecting pipe 4. A threaded column 7 is fixedly provided on the mounting plate 6. The mounting bracket also includes a base plate 8 arranged at the lower end of the connecting pipe 4. By providing the mounting plate 6, it is convenient to connect the anchor bolts to the generator and fix the generator.

[0042] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
