Description

Technical Field

[0001] The utility model relates to the technical field of bolt disassembly, in particular to a flange connection bolt disassembly device. Background Technique

[0002] In the modern industrial field, flange connections are widely used in the connection of pipelines, containers, and various mechanical equipment. However, when maintenance, repair, or component replacement of flange connections is required, disassembling the connection bolts often becomes a challenging task.

[0003] Traditional bolt disassembly methods usually rely on manual tools such as wrenches. However, with the development, the use of electric wrenches is also increasing. However, traditional flange connection bolts usually consist of bolts and nuts. When disassembling, the nut needs to be turned. However, during the turning process, since the bolt and the flange are independently arranged, turning the nut easily drives the bolt to rotate. Therefore, tools are needed to limit the position of the bolt. Most traditional disassembly devices do not have such a function, resulting in more laborious disassembly. Therefore, the utility model proposes a flange connection bolt disassembly device to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and propose a flange connection bolt disassembly device. By setting a fixing mechanism and a driving mechanism, when it is necessary to disassemble the flange connection bolt, the bolt can be limited in position to avoid synchronous rotation with the nut during the disassembly process, and no other tools are required, with high practicability.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A flange connection bolt disassembly device, including an electric wrench main body. A chute is opened at the upper end of the electric wrench main body. A moving plate is slidably connected inside the chute. A cross bar is fixedly connected to the side wall of the moving plate. One end of the cross bar away from the moving plate is fixedly connected to a fixing plate. A notch is opened at the lower end of the fixing plate. A limiting groove is opened on the inner wall of the notch. A fixing mechanism for fixing the bolt is arranged in the limiting groove. The fixing mechanism includes two symmetrically arranged clamping plates slidably connected in the limiting groove. Anti-slip rubber sleeves are sleeved on both clamping plates. A driving mechanism for driving the fixing mechanism is arranged in the limiting groove. A limiting mechanism for limiting the moving plate is arranged in the chute.

[0007] Preferably, the driving mechanism includes a double-headed threaded rod rotatably connected between the inner walls at both ends of the limiting groove. The double-headed threaded rod passes through the two clamping plates and is threadedly connected to them.

[0008] Preferably, a motor is fixedly connected to the side wall of the fixing plate, and the end of the output shaft of the motor is fixedly connected to the end of the double-headed threaded rod.

[0009] Preferably, the limiting mechanism includes a guide rod fixedly connected between the inner walls of both ends of the sliding groove, and the guide rod passes through the moving plate and is slidably connected thereto.

[0010] Preferably, the moving plate is elastically connected to the inner wall of the sliding groove by a spring, and the spring is sleeved on the guide rod.

[0011] Preferably, two handles are fixedly connected to the lower end of the electric wrench body, and the two handles are symmetrically arranged.

[0012] Preferably, a socket is rotatably connected to one end of the electric wrench body close to the fixing plate, and a rotating head is installed at the socket.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By providing the fixing mechanism and the driving mechanism, when it is necessary to disassemble the flange connection bolt, first align the notch of the fixing plate with the bolt head, then drive the output shaft of the motor to rotate, so that the clamping plates on both sides move closer to the middle to fix the bolt head, and then move the rotating head close to the nut on the other side and sleeve the nut, start the electric wrench body, and turn the nut to complete the disassembly of the bolt. It can limit the bolt to prevent it from rotating synchronously with the nut during the disassembly process, and there is no need to use other tools, so the practicability is relatively high.

[0015] 2. By providing the limiting mechanism, the moving plate slides in the sliding groove. During disassembly, the electric wrench body can move following the movement of the nut to avoid movement interference. At the same time, under the action of the guide rod, the stability of the moving plate and the entire fixing mechanism can be ensured, improving the practicability of the device.

[0021] In order to make the above-mentioned objects, features and advantages of the present utility model more obvious and understandable, the specific implementation manner of the present utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific implementations disclosed below.

[0022] Refer to Figures 1-4 , a flange connection bolt disassembly device, including an electric wrench body 1. A chute 4 is opened at the upper end of the electric wrench body 1. A moving plate 5 is slidably connected inside the chute 4. A cross bar 6 is fixedly connected to the side wall of the moving plate 5. One end of the cross bar 6 away from the moving plate 5 is fixedly connected to a fixed plate 7. A notch 8 is opened at the lower end of the fixed plate 7. A limit groove 12 is opened on the inner wall of the notch 8. A fixing mechanism for fixing the bolt is arranged in the limit groove 12. The fixing mechanism includes two symmetrically arranged clamping plates 11 slidably connected in the limit groove 12. Anti-slip rubber sleeves are sleeved on both clamping plates 11. The setting of the anti-slip sleeves can increase the friction between the clamping plates 11 and the bolt, and avoid slipping during clamping.

[0023] A driving mechanism for driving the fixing mechanism is arranged in the limit groove 12. The driving mechanism includes a double-headed threaded rod 13 rotatably connected between the inner walls at both ends of the limit groove 12. The double-headed threaded rod 13 passes through the two clamping plates 11 and is threadedly connected thereto. A motor 10 is fixedly connected to the side wall of the fixed plate 7. The end of the output shaft of the motor 10 is fixedly connected to the end of the double-headed threaded rod 13.

[0024] A limiting mechanism for limiting the moving plate 5 is arranged in the chute 4. The limiting mechanism includes a guide rod fixedly connected between the inner walls at both ends of the chute 4. The guide rod passes through the moving plate 5 and is slidably connected thereto. The moving plate 5 and the inner wall of the chute 4 are elastically connected by a spring 3. The spring 3 is sleeved on the guide rod. The guide rod limits the moving plate 5. The setting of the spring 3 can enable the moving plate 5 to quickly reset. At the same time, the electric wrench body 1 and the fixing mechanism are movably connected. When the nut moves, the electric wrench body 1 can follow the movement.

[0025] At the lower end of the electric wrench body 1, two handles 2 are fixedly connected. The two handles 2 are symmetrically arranged. One end of the electric wrench body 1 close to the fixing plate 7 is rotatably connected with a socket. A rotating head 9 is installed at the socket. The rotating head 9 is of a detachable and replaceable type, which can facilitate the use of different nuts. This technology is a mature existing technology and will not be elaborated here.

[0026] When the present utility model is in use, first, when it is necessary to disassemble the bolts on the flange, the notch 8 of the fixing plate 7 is sleeved on the bolt head. Subsequently, the output shaft of the driving motor 10 rotates. The rotation of the output shaft of the motor 10 drives the double-headed threaded rod 13 to rotate. The rotation of the double-headed threaded rod 13 can drive the two clamping plates 11 threadedly connected thereto to move closer to the middle, thereby realizing the clamping and fixing of the bolt. After the clamping is completed, the rotating head 9 is sleeved on the nut of the bolt. Subsequently, the electric wrench body 1 is driven. The electric wrench body 1 drives the rotating head 9 to rotate, screwing the nut to loosen the nut. During the loosening process, the nut moves relative to the bolt. During this process, the electric wrench body 1 can be moved so that the electric wrench body 1 can move along with the nut to complete the disassembly of the nut. After the disassembly is completed, the output shaft of the driving motor 10 rotates in the reverse direction, and the double-headed threaded rod 13 is rotated in the reverse direction, so that the clamping plates 11 on both sides loosen the bolt head to the two sides.

[0027] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
