Description

Technical Field

[0001] This utility model relates to the field of explosion-proof operating console technology, and specifically to an explosion-proof operating console. Background Technology

[0002] When extracting oil, the requirements for the equipment used are usually quite strict. In particular, the equipment on offshore drilling platforms must be explosion-proof. Using explosion-proof equipment can minimize the risk of explosions and fires and also ensure the safety of the workers.

[0003] However, many of the electrical and control components in existing well logging equipment are specialized and not explosion-proof. Therefore, they need to be placed inside an explosion-proof control panel during use. The electrical modules inside the control panel are operated by a control handle, and the electrical modules control the electrical components inside the explosion-proof control panel to work, so that the electrical equipment can also play an explosion-proof role when it is working.

[0004] However, since the hydraulic pump control handle in the logging equipment is a Hall effect control handle, it needs to be moved back and forth to control the rotation position of the electrical module inside the control panel. Therefore, the space between the handle and the control panel is relatively large, making it difficult to achieve an effective seal, which has a certain impact on the explosion-proof effect. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an explosion-proof operating console to solve the problem mentioned in the background art that when electrical modules are directly controlled via a handle, the space that needs to be effectively sealed is large due to the need to move the handle back and forth.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An explosion-proof operating console includes an explosion-proof box, an electrical module, and a control handle. It also includes a housing, a rotating shaft, a swing assembly, and a locking assembly. The housing is fixedly installed at the inner top of the explosion-proof box. The rotating shaft is rotatably installed at the inner bottom of the housing via a mounting bracket. The control handle is fixedly installed on the outer side wall of the rotating shaft. The swing assembly is disposed on the housing for connecting the control handle and the electrical module. The locking assembly is disposed at the top of the explosion-proof box for fixing the control handle after it has been moved.

[0010] Furthermore, the swing assembly includes a first shift fork, a drive shaft, and a second shift fork. The first shift fork is fixedly mounted on the rotating shaft. One end of the drive shaft is fixedly mounted on the side of the first shift fork and is rotatably mounted through the side of the housing. The second shift fork is fixedly mounted on the other end of the drive shaft, and the electrical module is fixedly mounted on the side of the second shift fork via a connecting roller.

[0011] Furthermore, the locking assembly includes a fixing frame, a locking rod, and a fixing block. The fixing frame is fixedly installed on the top of the explosion-proof box, and a fixing groove is provided on the top of the fixing frame. The locking rod is slidably installed through the top of the explosion-proof box and the top of the fixing frame, and a U-shaped frame is fixedly installed on the top of the locking rod. Two fixing blocks are provided, and both fixing blocks are fixedly installed on the side of the drive shaft, and a limit groove is provided on the fixing block.

[0013] In order to fix the locking rod to the fixing frame, the bottom end of the locking rod is adapted to the limiting groove of the fixing block, and the bottom end of the U-shaped frame is adapted to the fixing groove of the fixing frame.

[0014] In order to fix the control handle after it has been turned, further, when the bottom end of the locking rod is inserted into the limiting groove of the fixing block, the bottom end of the U-shaped frame is inserted into the fixing groove of the fixing frame.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides an explosion-proof operating platform, which has the following beneficial effects:

[0017] 1. In this utility model, when the control handle drives the electrical module to control the electrical switch, the swing component can connect the control handle and the electrical module, thereby reducing the through space of the housing and making it more convenient to seal it.

[0018] 2. In this utility model, after the toggle is completed, the control handle can be locked and fixed by the locking component, thereby preventing the control handle from rotating due to vibration during equipment operation, which in turn drives the electrical module to change position and thus changes the switch of the equipment.

[0019] Therefore, through the cooperation between the housing, rotating shaft, swing assembly and locking assembly, the explosion-proof operating console can connect the control handle and electrical module, making the space through the housing smaller. Compared with using Hall effect control handles to move back and forth, it can better and more conveniently seal the through-hole. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1 to 6An explosion-proof operating console includes an explosion-proof box 1, an electrical module 2, and a control handle 3. It also includes a housing 4, a rotating shaft 5, a swing assembly, and a locking assembly. The housing 4 is fixedly installed on the inner top of the explosion-proof box 1. The rotating shaft 5 is rotatably installed on the inner bottom of the housing 4 via a mounting bracket. The control handle 3 is fixedly installed on the outer side wall of the rotating shaft 5. The swing assembly is disposed on the housing 4 for connecting the control handle 3 and the electrical module 2. The locking assembly is disposed on the top of the explosion-proof box 1 for fixing the control handle 3 after it is moved.

[0029] like Figure 2 and Figure 3 As shown, when using the equipment, the equipment is first placed inside the explosion-proof box 1. Then, the control handle 3 and the electrical module 2 are connected by the swing assembly. The control handle 3 is located at the top of the explosion-proof box 1, and the electrical module 2 is located inside the explosion-proof box 1. When it is necessary to control the switch of the equipment, the position of the electrical module 2 can be controlled by the swing assembly. The swing assembly includes a first fork 6, a drive shaft 7, and a second fork 8. The first fork 6 is fixedly installed on the rotating shaft 5. One end of the drive shaft 7 is fixedly installed on the side of the first fork 6, and the drive shaft 7 is rotatably installed through the side of the housing 4. The second fork 8 is fixedly installed on the other end of the drive shaft 7, and the electrical module 2 is fixedly installed on the side of the second fork 8 by the connecting roller 15.

[0030] Specifically, the connecting rod inside the control handle 3 is connected to the rotating shaft 5. By moving the control handle 3 back and forth, the rotating shaft 5 is driven to rotate, which in turn drives the first shift fork 6 to rotate. Under the connection of the transmission shaft 7, the second shift fork 8 rotates synchronously. The second shift fork 8 then drives the electrical module 2 inside the explosion-proof box 1 to rotate. After detecting the position information, the electrical module 2 determines the position and outputs the direction and magnitude of the control signal, thereby controlling the switch of the electrical equipment inside the explosion-proof box 1 to start or stop it. It should be noted that the control of the equipment switch by the electrical module 2 is a known technology and can be controlled by relays and transistors, etc.

[0031] like Figure 5 and Figure 6 As shown, after the rotation is completed, the drive shaft 7 can be fixed by the locking assembly. The locking assembly includes a fixing frame 9, a locking rod 10 and a fixing block 11. The fixing frame 9 is fixedly installed on the top of the explosion-proof box 1, and a fixing groove is opened on the top of the fixing frame 9. The locking rod 10 is slidably installed through the top of the explosion-proof box 1 and the top of the fixing frame 9, and a U-shaped frame 14 is fixedly installed on the top of the locking rod 10. There are two fixing blocks 11. Both fixing blocks 11 are fixedly installed on the side of the drive shaft 7, and a limit groove is opened on the fixing block 11.

[0032] Specifically, when the device is not switched on, the limiting groove of one of the fixing blocks 11 on the drive shaft 7 faces upwards. Because the bottom end of the locking rod 10 matches the limiting groove of the fixing block 11, and the bottom end of the U-shaped bracket 14 matches the fixing groove of the fixing frame 9, and when the bottom end of the locking rod 10 is inserted into the limiting groove of the fixing block 11, the bottom end of the U-shaped bracket 14 is inserted into the fixing groove of the fixing frame 9, the locking rod 10 is moved downwards, inserting its bottom end into the limiting groove of one of the fixing blocks 11, and at this time, the U-shaped bracket 14 is inserted into the fixing groove of the fixing frame 9, thus limiting the drive shaft 7. After the drive shaft 7 rotates, when the electrical module 2 rotates to the switch to turn on the device, the other fixing block 11 of the drive shaft 7 rotates to directly below the locking rod 10. At this time, pulling the locking rod 10 inserts it into the limiting groove of the other fixing block 11, fixing it in place. This is the device's on state.

[0033] like Figure 4 As shown, when the equipment is working, it will vibrate. In order to better support the drive shaft 7 and the electrical module 2, a support assembly can be used to support the bottom end of the drive shaft 7. The support assembly includes a support rod 12 and a support ring 13. The support rod 12 is fixedly installed on the side of the housing 4, and the support ring 13 is fixedly installed on the top of the support rod 12. The connecting roller 15 is rotatably installed on the support ring 13. Specifically, the drive shaft 7 rotates on the support ring 13. Therefore, the support rod 12 and the support ring 13 can support the bottom end of the drive shaft 7.

[0034] Working Principle: When using this explosion-proof control panel, the equipment is first placed inside the explosion-proof enclosure 1. The electrical module 2 is located inside the enclosure 1 and is used to control the switch of the equipment. At this time, only the control handle 3 is located outside the explosion-proof enclosure 1. When it is necessary to turn on the equipment, the control handle 3 is moved back and forth, which drives the rotating shaft 5 to rotate. The rotating shaft 5 drives the first shift fork 6 to rotate. Under the connection of the transmission shaft 7, the second shift fork 8 rotates synchronously. The second shift fork 8 then drives the electrical module 2 inside the explosion-proof enclosure 1 to rotate. After detecting the position information, the electrical module 2 determines the position and outputs the direction and magnitude of the control signal, thereby controlling the switch of the electrical equipment inside the explosion-proof enclosure 1 to start it. When the control handle 3 is moved, the locking rod 10 is pulled up. After opening, the locking rod 10 is moved down, and the bottom end of the locking rod 10 is inserted into the transmission shaft 7. The transmission shaft 7 is fixed in the limiting groove of one of the fixing blocks 11, and the bottom end of the U-shaped frame 14 is inserted into the fixing groove of the fixing frame 9 to fix the transmission shaft 7, thereby limiting the control handle 3 to prevent it from changing position due to contact. It should be added that the transmission shaft 7 passes through the housing 4, so it can be installed at the connection point by a sealing strip or sealing ring to seal it. The locking rod 10 is slidably installed at the top of the explosion-proof box 1, and a sealing ring can also be installed for sealing. This method of sealing is relatively simple. It should also be added that there are many ways to install the control handle 3 and the explosion-proof box 1. One of them is to open holes at the top of the explosion-proof box 1 and the housing 4 and install bearings. The connecting rod of the control handle 3 passes through the inner ring of the bearing, so that the connecting rod can rotate smoothly. Sealed bearings can be used to ensure sealing.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
