Description

Technical Field

[0001] This utility model relates to the technical field of bolt removal equipment, specifically to a device for quickly removing bolts. Background Technology

[0002] Large cast iron bolts are often used when installing large machinery to press-fit mechanical parts on the equipment and thus fix the parts in place.

[0003] In related technologies, when large ball mills, reducers, gears, and other equipment or components need maintenance, it is necessary to remove the large cast iron bolts. However, due to the initial interference fit of the components, the bolts fixing them are often difficult to remove when maintenance is required. Traditional removal methods, such as gas cutting and oscillating hammers, are acceptable for removing smaller bolts, but for larger bolts, these methods are time-consuming and laborious, and can easily deform the bolt holes, making subsequent assembly inconvenient. Therefore, a method using electric welding combined with pure oxygen has been introduced to remove the bolts. By electric welding at the center of the bolt and nut in the cast iron, and simultaneously blowing pure oxygen into this position, the bolt is ignited, causing the cast iron bolt to lose the fastening force of the interference fit. Then, the bolt is removed by hammering.

[0004] In this method of disassembling bolts, after igniting the central axis point of the cast iron bolt, the pipe supplying pure oxygen is continuously moved axially towards the cast iron bolt. Although this method can quickly disassemble large bolts, it requires a high level of skill, making it inconvenient to disassemble bolts in this way. To solve the above problems, a device for quickly disassembling bolts is proposed. Utility Model Content

[0005] In view of this, the present invention provides a device for quickly removing bolts. The present invention uses an air nozzle directly facing the central axis of the bolt to spot weld the central axis of the nut, and simultaneously opens a pure oxygen cylinder, allowing pure oxygen to enter the guide tube inside the oxygen delivery pipeline through the connecting component. The guide tube then precisely sprays the pure oxygen from the air nozzle into the bolt's ignition position. By activating an electric push rod, the oxygen delivery pipeline moves inward toward the bolt's central axis. By utilizing the high temperature generated instantaneously in a near-pure oxygen environment, a through hole is burned into the bolt's central axis, thereby destroying the bolt's internal stress and facilitating the removal of large cast iron bolts subjected to interference fit.

[0006] To solve the above-mentioned technical problems, this utility model provides a device for quickly removing bolts, including an oxygen delivery pipe, a connecting component at the air inlet end of the oxygen delivery pipe, a pure oxygen cylinder at the air inlet end of the connecting component, an air nozzle at the air outlet end of the oxygen delivery pipe, a positioning ring at the rear of the surface of the oxygen delivery pipe, a first support member at the bottom of the positioning ring, a second support member at the bottom of the pure oxygen cylinder, and a moving device at the bottom of the first and second support members. The moving device is slidably connected to the first and second support members respectively, and a gripping part is provided at the bottom of the moving device.

The connecting rods are used to connect the positioning ring to the support block, and then to connect the oxygen delivery pipe to the support block. Each connecting rod has a support block at its bottom, which is used to connect the connecting rod to the slider. Each support block has a slider at its bottom, which is used to connect the connecting rod to the slide rail.

[0010] The second support component includes a connecting plate fixed to the bottom of the connecting compartment. The connecting plate is used to support the connecting compartment and also to connect the connecting compartment to the support rod. A support rod is provided on each side of the bottom of the connecting plate. The support rod is used to connect the connecting compartment to the support block. A support block is provided at the bottom of each support rod. A slider is provided at the bottom of each support block, thereby connecting the connecting compartment to the slide rail.

[0011] The moving device includes a support plate for supporting two slide rails. A pair of slide rails are provided on the upper surface of the support plate for the movement of sliders. Each slider is slidably engaged with the slide rail on the same side. The two sliders are connected axially by a linkage rod, which connects the two sliders on the same side into one unit. When an electric push rod pushes a pair of sliders, all sliders will move synchronously. An electric push rod is provided at the rear of each slide rail, which pushes the slider to move within the slide rail, thereby causing the first support member and the second support member to move synchronously, thus causing the oxygen delivery pipeline and the pure oxygen cylinder to move synchronously. The telescopic end of each electric push rod is connected to the slider closest to it on the same side.

[0012] The grip includes a main grip rod fixed to the front end of the bottom of the support plate. The main grip rod is used by the operator to hold this mobile device. The surface of the main grip rod is provided with a protective sleeve to increase the friction between the hand and the main grip rod, making it more convenient and comfortable for the operator to hold the main grip rod. A secondary grip rod is provided at the rear of the bottom of the support plate. The secondary grip rod makes it easier for the operator to hold the mobile device and achieves higher horizontal accuracy.

[0013] A movement button is located at the front of the main handle. The movement button is used to operate the electric push rod. An air intake button is located next to the movement button. The air intake button is used to control the opening and closing of the pure oxygen cylinder outlet, making it easier to operate the device.

[0014] Each slide rail has a positioning block at the front. The positioning block is used to fit against the component that installs the cast iron bolt, making it easier for the air nozzle to accurately locate the center position of the cast iron bolt. Each positioning block has several protrusions on the side away from the slide rail. The protrusions are used to increase the friction between the positioning block and the component that installs the cast iron bolt, making it easier for the air nozzle to locate the center of the bolt.

With the nozzle directly facing the center axis of the bolt, spot weld the center axis of the nut. Simultaneously open the pure oxygen cylinder, allowing pure oxygen to enter the guide tube inside the oxygen supply pipeline through the connecting component. Then, through the guide tube, the pure oxygen is precisely sprayed from the nozzle into the bolt ignition position. By activating the electric push rod, the oxygen supply pipeline moves into the center axis of the bolt. By using the high temperature generated instantaneously in a near-pure oxygen environment, a through hole is burned into the center axis of the bolt, thereby destroying the internal stress of the bolt. This allows for easy removal of large cast iron bolts subject to interference fit.

[0016] 2. The support plate is used to support two slide rails, which are used for the movement of the sliders. The linkage rod is used to connect the two sliders on the same side into one unit. When the electric push rod pushes a pair of sliders, all the sliders will move synchronously.

[0037] Working principle: By aligning the nozzle 103 with the central axis of the cast iron bolt and nut, and simultaneously opening the pure oxygen cylinder 102 through the center of the welded bolt, pure oxygen enters the guide tube 500 within the oxygen supply pipeline 100 through the connecting component 101. The pure oxygen is then precisely sprayed from the nozzle 103 into the bolt ignition location. By activating the electric push rod 303, the first support 200 and the second support 201 move synchronously, causing the oxygen supply pipeline 100 to move inward toward the bolt's central axis. By utilizing a near-pure oxygen environment, the bolt is ignited under oxygen pressure, instantly generating high temperatures that burn a through hole into the bolt's central axis. After the through hole is burned out, the internal stress of the bolt is destroyed, and the bolt can be removed by striking it with a hammer or similar object. This allows for the convenient removal of large cast iron bolts subject to interference fits.
