Description

Technical Field

[0001] The present application relates to the field of anchor bolt technology, and in particular to a prestressed anchor bolt nut disassembly device. Background Art

[0002] Prestressed anchor bolts primarily consist of steel bars, prestressing tendons, and an anchoring system. The steel bars and tendons are embedded in the concrete, forming a single unit. The anchoring system secures the tendons, creating a prestressed force. This prestressed force increases the concrete's bearing capacity and improves the stability of the structure.

[0003] In the traditional prestressed anchor bolt installation process, the anchor bolt nuts are usually removed manually using a wrench. However, due to the large number of nuts, the labor intensity is high. Utility Model Content

[0033] The above description is merely an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.

[0034] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings to facilitate understanding by technical personnel.

[0035] Example 1:

[0036] See also Figure 1 A prestressed anchor bolt nut disassembly device, the prestressed anchor bolt nut disassembly device comprising:

[0037] Platform 1;

[0038] A rotating member 2 is provided on the support platform 1, and a sleeve 3 is connected to the rotating member 2;

[0039] A driving member 4 is provided on the support platform 1 and is transmission-connected to the rotating member 2;

[0040] The sleeve 3 is provided with a hexagonal hole matching the anchor nut. When the driving member 4 is actuated, the rotating member 2 is driven to rotate around its own axis, thereby driving the sleeve 3 to rotate synchronously.

[0041] Specifically, the upper end surface of the platform 1 is fixedly connected to the bottom of the rotating member 2 and the driving member 4. This fixed connection enhances the strength of the joint and ensures stability during transmission. The rotating member 2 and the sleeve 3 are detachably connected, facilitating replacement of the sleeve 3. The sleeve 3 has a hexagonal hole that matches the anchor nut, allowing the anchor nut to nest tightly within the sleeve 3, thereby facilitating the sleeve 3 to drive the nut. The driving member 4 and the rotating member 2 can be connected via a chain or belt.

[0042] During construction, the device is placed on the ground, the anchor bolt is passed through the sleeve 3 and fixed to the nut, and the driving member 4 is activated. When the driving member 4 is activated, the rotating member 2 is driven to rotate about its own axis, thereby driving the sleeve 3 to rotate synchronously, thereby achieving the removal of the nut. This application removes the anchor bolt nut through the transmission coordination of the driving member 4, the rotating member 2 and the sleeve 3, replacing the manual removal method using a wrench, reducing labor intensity.

[0043] Example 2:

[0044] See also Figure 1 and Figure 2 Based on the first embodiment, optionally, the rotating member 2 includes:

[0045] A fixed pier 5 is provided with an arc-shaped installation groove, in which a bearing 6 is provided. The outer ring of the bearing 6 is fixedly connected to the installation groove, and the inner ring of the bearing 6 is fixedly connected to the sleeve 3.

[0046] Specifically, the bottom of the fixing pier 5 is fixedly connected to the end surface of the base 1. The top of the fixing pier 5 defines an arcuate mounting groove that matches the outer ring of the bearing 6. The bearing 6 is fixedly mounted within the arcuate mounting groove. The arcuate mounting groove increases the contact area with the outer ring of the bearing 6, thereby improving the stability of the bearing 6. The outer diameter of the sleeve 3 matches the inner ring diameter of the bearing 6, facilitating the connection between the inner ring of the bearing 6 and the sleeve 3. As a result, when the sleeve 3 rotates, the inner ring of the bearing 6 rotates synchronously with it, while the outer ring remains stationary, providing support for the sleeve 3 through the bearing 6.

[0047] Optionally, the driving member 4 includes:

[0048] A fixed plate 7 is provided with a pulley 8 rotatably mounted on one side thereof, and a handle 9 is provided on the pulley 8;

[0049] The pulley 8 is connected to the sleeve 3 via a transmission belt 10 .

[0050] Specifically, the fixing plate 7 is in the shape of an elongated strip, the bottom of which is fixedly connected to the end face of the platform 1, and a pulley 8 is rotatably mounted on one side of the upper portion of the fixing plate 7. A handle 9 is fixedly connected to the end face of the pulley 8 away from the fixing plate 7. The pulley 8 is connected to the sleeve 3 via a transmission belt 10, and the force on the pulley 8 is transmitted to the sleeve 3 via the transmission belt 10. In this way, when the handle 9 is rotated, the pulley 8 is driven to rotate, thereby driving the sleeve 3 to rotate synchronously.

[0051] In addition, it is conceivable that the pulley 8 can be driven by a motor in order to further reduce labor intensity.

[0052] Optionally, a flexible rubber layer is bonded to the surface of the handle 9 .

[0053] Specifically, a flexible rubber layer is bonded to the surface of the handle 9 , which, on the one hand, increases the friction between the hand and the handle 9 and facilitates force application; on the other hand, it reduces damage to the hand caused by the handle 9 and improves the comfort of holding.

[0054] Optionally, the surface of the flexible rubber layer is provided with patterns.

[0055] Specifically, providing patterns on the surface of the flexible rubber layer can increase the friction coefficient, thereby further improving the friction between the hand and the handle 9.

[0056] Example 3:

[0057] See also Figure 3 Based on the above embodiment, optionally, a lubricating oil nozzle 11 is provided on the side of the bearing 6 away from the sleeve 3, and the fixed end of the lubricating oil nozzle 11 is detachably connected to the mounting plate 12, and the bottom of the mounting plate 12 is fixed to the side of the base 1.

[0058] Specifically, mounting plate 12 should avoid interference with the anchor bolts, and therefore its height should be no higher than the bottom of the inner ring of bearing 6. A mounting hole for lubricating oil nozzle 11 is provided on the top of mounting plate 12. Lubricating oil nozzle 11 is removably mounted within this hole, with the nozzle of lubricating oil nozzle 11 facing the ball bearing of bearing 6. Because a large number of nuts require removal, and bearing 6 must maintain good transmission performance at all times, lubricating oil nozzle 11 is installed on one side of bearing 6 to facilitate lubrication.

[0059] Optionally, the lubricating oil nozzle 11 is connected to a lubricating oil source through a hose.

[0060] Specifically, when lubrication is required, the lubricating oil nozzle 11 is connected to the oil pump and the lubricating oil source through a hose. The operation and shutdown of the lubricating oil nozzle 11 can be controlled manually, or the controller can be used to control the lubricating oil nozzle 11 to inject lubricating oil into the bearing 6 at a regular and quantitative manner.

[0061] It should be noted that components such as hoses and oil pumps are common knowledge and are not shown in the figures, so they will not be described in detail here.

[0062] It should be noted that the structures and / or installation methods not detailed in this application are known to those skilled in the art in combination with common knowledge and / or existing technologies, and are not the focus of disclosure in this application and will not be further elaborated here.

[0063] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application; the dimensions of the drawings are not related to the specific objects, and the dimensions of the objects can be changed arbitrarily.
