Description

Technical Field

[0001] This utility model relates to the field of bolt tensioner technology, specifically to an auxiliary device for loading and unloading a large bolt hydraulic tensioner. Background Technology

[0002] A bolt tensioner is a mechanical device specifically designed to apply tension to bolts, primarily used for fastening structural components. It stretches the bolts hydraulically or mechanically, creating sufficient preload between the bolt and the connecting parts, thereby improving the stability and safety of the connection. To prevent the bolt tensioner from shifting or jamming during use, an auxiliary device for loading and unloading the hydraulic bolt tensioner is required.

[0003] However, the existing auxiliary devices for loading and unloading large bolt hydraulic tensioners have weak quick connection and disassembly functions. During use, it is not easy to quickly connect and disassemble the device and the bolt hydraulic tensioner according to the needs of the application scenario, which reduces the convenience of the device. Moreover, the existing auxiliary devices for loading and unloading large bolt hydraulic tensioners have weak lubrication. When the device is used for a long time or many times, it may cause jamming during the connection of the bolt hydraulic tensioner, which will affect the smoothness of the connection. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary device for loading and unloading large bolt hydraulic tensioners to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An auxiliary device for loading and unloading a large bolt hydraulic tensioner includes a fixed plate. A groove is formed in the middle of the top surface of the fixed plate. The tensioner body is slidably connected inside the groove. The tensioner body has slots on both sides of its surface. A sliding groove is formed on both sides of the fixed plate. A limit component is slidably connected inside the sliding groove. The limit component includes a sliding rod. The surface of the sliding rod is slidably connected inside the sliding groove. A lubrication component is fixedly connected to one end of the top of the fixed plate. The lubrication component includes a lubrication box. The bottom of the lubrication box is fixedly connected to one end of the top of the fixed plate.

[0007] Preferably, the top of the fixing plate has two sets of threaded grooves, and the inside of each set of threaded grooves is threaded with a fixing screw. The bottom of the fixing plate is fixedly connected with two sets of shock-absorbing buffer plates.

[0008] Preferably, the limiting component further includes a convenient block, the middle of one side of which is fixedly connected to one side of the sliding rod, and a spring is fixedly connected to one side of the convenient block, the inside of which is sleeved on the surface of the sliding rod.

[0009] Preferably, a limiting block is fixedly connected to the other side of the sliding rod, the surface of the limiting block is slidably connected to the inside of the slot, and the other side of the spring is fixedly connected to the surface of the fixing plate.

[0010] Preferably, the lubrication assembly further includes an oil inlet, the bottom of which is located in the middle of the top surface of the lubrication tank, a closing cover is snapped into the inside of the oil inlet, and a connecting pipe is connected through the bottom of the lubrication tank.

[0011] Preferably, one end of the connecting pipe is connected to a lubricating layer, and the surface of the lubricating layer is fixedly connected to the inside of the groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This auxiliary device for loading and unloading a large bolt hydraulic tensioner, through the setting of a limiting component, a groove, and a slot, allows the operator to first align the tensioner body with the inside of the groove and insert it. During insertion, the surface of the tensioner body will contact the limiting block and move backward against the limiting block, spring, and sliding rod. When the tensioner body is inserted to a certain position, the spring will drive the sliding rod and the limiting block to rebound, and the surface of the limiting block will be locked inside the slot, thus limiting the tensioner body. For disassembly, the operator needs to push two sets of convenient blocks backward. The convenient blocks will drive the sliding rod, spring, and limiting block to move backward, separating the limiting block from the slot, and then the tensioner body can be pulled out. This achieves quick installation and disassembly of the tensioner body, improving the convenience of the device.

[0014] 2. This auxiliary device for loading and unloading a large bolt hydraulic tensioner, through the setting of lubrication components, fixing threads, and shock-absorbing buffer plates, allows the operator to fix and limit the device through two sets of fixing screws inside the threaded grooves during use, preventing deviation during operation. The shock-absorbing buffer plates reduce the impact of external vibrations. Depending on the usage time and frequency, the operator can also remove the closing cover and pour lubricating oil into the lubrication tank. The lubricating oil is transported to the lubrication layer through the lubrication tank and connecting pipes. The lubrication layer absorbs the lubricating oil, lubricating the bottom of the tensioner body during use, making the installation and disassembly of the tensioner body and device smoother, thereby improving the device's practicality.
