Description

[0001] The utility model relates to the technical field of equipment anti-theft, in particular to an integrated anti-theft sealing device for a reduction gearbox. Background Art

[0002] In the daily production process, the reducer is a very common mechanical device, especially in oil field production work, where almost every oil well pumping unit is equipped with a reducer to transmit power while reducing the speed of the device. At the oil production site, the pumping units and their reducers usually work in the field and are very scattered. They can only be monitored through daily inspections. The monitoring capacity is very limited, resulting in frequent theft of the lubricating oil in the reducer, causing poor lubrication of the gears in the reducer and then damage to the equipment. The reducers currently used do not have anti-theft capabilities. The lubricating oil inside can be removed by simply rotating the bolts of the reducer cover or the plug at the bottom. In order to prevent the loss of lubricating oil, some reducers are anti-theft by welding the bottom plug. Although this can effectively increase the difficulty of theft and prevent the loss of lubricating oil, the workload is greatly increased when replacing the lubricating oil due to the welding of the plug, resulting in an increase in workload. In the prior art, there is an anti-theft device for a reduction gearbox. The device is provided with a connecting rod at the bottom of the reduction gear upper cover to clamp the upper cover and the reduction gear body together, and then the connecting rod is fixed by a lock body. After the connecting rod fixes the upper cover to the reduction gear body, the reduction gear upper cover can only be opened with a key. The above technology has the following problems: First, the force on the upper cover only acts on the two connecting rods, and the structural strength of the connecting rod after being connected to the linkage shaft is low, and the degree of protection is limited in the event of violent situations such as forced opening; Second, the exposed lock body gives thieves the opportunity to unlock and steal, and long-term direct exposure to the external environment and environmental influences such as rain and snow can easily damage the lock body, making the device difficult to repair. Therefore, in response to the above shortcomings, an integrated anti-theft sealing device for a reduction gearbox is proposed. Summary of the Invention

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-2As shown, the utility model provides an integrated anti-theft sealing device for a reduction gearbox, comprising: a reduction gearbox cover 1 and a locking plate 2. The locking plate 2 is located below the reduction gearbox cover 1. The reduction gearbox cover 1 is the existing oil pump reduction gearbox cover. The reduction gearbox cover 1 is usually located at the top of the reduction gearbox body to seal the reduction gearbox body, and a number of fixing bolts are provided on the edge of the reduction gearbox cover 1 to fix the reduction gearbox cover 1 to the reduction gearbox body. The locking plate 2 is mainly used to clamp the reduction gearbox cover 1 and the reduction gearbox body, thereby locking the reduction gearbox cover 1 to the reduction gearbox body. A vertically upward screw 3 is provided in the middle of the locking plate 2, and the screw 3 passes through the reduction gearbox cover 1 upward. Before installing the reduction gearbox cover 1, the screw 3 is first passed through the reduction gearbox cover 1 from bottom to top, and a nut is installed at the top of the screw 3. After tightening the nut, it cooperates with the locking plate 2 to tighten the reduction gearbox cover 1, thereby fixing the position of the locking plate 2. The width of the locking piece 2 is smaller than the width of the reduction gear upper cover 1, and the length of the locking piece 2 is larger than the width of the reduction gear upper cover 1. When installing the locking piece 2, first align the long end of the locking piece 2 with the long end of the reduction gear upper cover 1, and then install the reduction gear upper cover 1 on the reduction gear body. At this time, the locking piece 2 is placed in the reduction gear body along with the reduction gear upper cover 1. Turn the nut to loosen the locking piece 2. At this time, turn the screw 3 to drive the locking piece 2 to rotate synchronously. After rotating the locking piece 2 90°, the long end of the locking piece 2 is perpendicular to the long end of the reduction gear upper cover 1. Then tighten the nut and the locking piece 2 to tighten the reduction gear upper cover 1. The length of the locking plate 2 is greater than the width of the reducer cover 1. At this time, the long ends of the locking plate 2 extend out of the reducer cover 1 to the left and right sides. When the reducer cover 1 is lifted, the locking plate 2 moves upward with the reducer cover 1. The upper surface of the part of the locking plate 2 extending out of the reducer cover 1 contacts the lower surface of the top edge of the reducer body to clamp the locking plate 2 and prevent the locking plate from continuing to move upward. Since the locking plate 2 is now clamped and fixed to the reducer cover 1 by the nut and screw 3, the locking plate 2 drives the reducer cover 1 to be fixed to the top of the reducer body. The reducer cover 1 cannot be opened without disassembling or damaging the nut.

[0022] In order to maintain uniform force on the locking plate 2 and the reducer upper cover 1 , the locking plate 2 and the reducer upper cover 1 are usually arranged concentrically, and the screw 3 is located in the middle of the locking plate 2 .

[0023] A sealed anti-theft box 4 is provided above the reducer cover 1. The portion of the screw rod 3 that passes through the reducer cover 1 is located in the anti-theft box 4. The anti-theft box 4 wraps the top of the screw rod 3 to protect the top of the screw rod 3 and the nut. Without opening the anti-theft box 4, the nut installed on the screw rod 3 cannot be removed, and thus the reducer cover 1 cannot be opened, thus realizing the anti-theft function. Without opening the anti-theft box 4, if you want to open the reducer cover 1, you need to apply an upward force to the reducer cover 1, and the magnitude of the force needs to be sufficient to deform the locking plate 2 or destroy the integrity of the thread between the screw rod 3 and the nut, which greatly increases the difficulty of theft. Compared with the prior art, the portion used to lock the reducer cover 1 does not have movable connection parts such as a connecting shaft and a long rod, but is a whole. Its strength and the amount of force it can withstand are significantly improved, and it has better anti-theft performance. Typically, the lock plate 2 is made of stainless steel with a thickness between 4mm and 8mm, which is sufficient to withstand the stress generated by most theft incidents. In special circumstances where the maximum stress that the lock plate 2 can withstand is higher, the thickness of the lock plate 2 can be further increased without affecting the normal operation of the reducer. To ensure that the lock plate 2 can be smoothly installed into the reducer along with the reducer cover 1 and rotated underneath the reducer cover 1, when the lock plate 2 and the reducer cover 1 are oriented in the same direction, the edge of the lock plate 2 should be approximately 2cm away from the end faces of the top opening of the reducer body.

[0024] To facilitate the opening, closing, and disassembly of the gearbox cover 1, an openable cover is provided on the anti-theft box 4. A remote control lock 5 is provided on the gearbox cover 1, and a lock tongue pops out when the remote control lock 5 is actuated. A lock button 6 is provided on the edge of the cover corresponding to the remote control lock 5, and the lock button 6 engages with the lock tongue of the remote control lock 5. Typically, the anti-theft box 4 is square, with the gearbox cover 1 serving as the bottom surface of the anti-theft box 4. Three of the four front, back, and left and right sides of the anti-theft box 4 are formed by welding the box body to the gearbox cover 1. Typically, the left, right, and rear surfaces of the anti-theft box 4 are formed by welding. The top surface and front surface of the anti-theft box 4 are integrally cast to form an L-shaped cover. The top of the cover and the top of the rear surface of the anti-theft box 4 are connected by a hinge to form an openable cover that can be flipped up and down. To prevent thieves from opening the anti-theft box 4 by removing the hinge, the hinge is installed on the inner wall of the anti-theft box 4. The remote control lock 5 is a common tool that can be purchased directly. After the remote control lock 5 is powered on, the lock tongue of the remote control lock 5 can be controlled to be ejected and retracted by a matching external remote control. After the remote control lock 5 is installed on the gearbox upper cover 1 inside the anti-theft box 4, a lock box 6 is installed on the edge of the upper cover of the anti-theft box 4. After the anti-theft box 4 is buckled, the lock tongue of the remote control lock 5 is controlled to be ejected. At this time, the lock tongue extends into the lock box 6. Because the lock tongue blocks the lock box 6, the upper cover of the anti-theft box 4 cannot be flipped up and opened. Without the control of the matching remote control, the lock tongue cannot be controlled to be retracted, thereby achieving the anti-theft function. Generally, a magnet is provided in the lock box 6. The position of the magnet corresponds to the position of the lock tongue of the remote control lock 5. When the anti-theft box 4 is buckled, the magnet in the lock box 6 attracts the lock tongue in the remote control lock 5 under its own magnetic effect, locking the lock box 6 on the anti-theft box 4. Even if the remote control lock 5 is powered off, the magnet will attract the lock tongue and maintain the lock tongue in position, so that the remote control lock 5 can remain locked and the anti-theft box 4 can be sealed even if the power is off.

[0025] The anti-theft box 4 has a power hole extending through it on its side wall, and the remote control lock 5 is provided with an external power cord 7 extending out of the power hole. After the remote control lock 5 is locked by controlling the lock tongue to pop out, the power to the anti-theft box 4 is cut off and the external power cord 7 is led out of the anti-theft box 4. The remote control lock 5 remains locked after the power is cut off. In this case, in addition to the matching remote control, the remote control lock 5 needs to be powered in order to open it, further increasing the difficulty of theft and strengthening the device's anti-theft capabilities. At the same time, removing the power supply of the remote control lock 5 can prevent the loss of power in the power supply during long-term outdoor operation. It also prevents the power supply from being damaged and rotted by impurities such as moisture and oil vapor during long-term operation inside the anti-theft box 4, thereby extending the service life of the device.

[0026] It should be noted that the remote control lock 5 is equipped with a separate power box and remote control. The power box is provided with a connector for the external power cord 7. Normally, the power box is equipped with batteries as supplied by the store. During inspection and maintenance work, the staff will connect the power box loaded with batteries to the external power cord 7 through the connector to provide power to the remote control lock 5. After that, the remote control can be used to control the remote control lock 5 and realize the opening and closing of the anti-theft box 4.

[0027] After a long period of operation, the lubricating oil in the gearbox is consumed. At this time, the lubricating oil needs to be injected into the pumping unit to replenish the lubricating oil in the pumping unit. The gearbox cover 1 is provided with a refill pipe 8 extending into the gearbox. The refill pipe 8 includes an elbow and a universal joint. The fixed end of the universal joint is connected to the gearbox cover 1, and the bottom end of the elbow is connected to the movable end of the universal joint. When refilling the lubricating oil, the lubricating oil can be injected into the refill pipe 8, and the lubricating oil flows down the refill pipe 8 into the gearbox, thereby replenishing the lubricating oil in the gearbox. The universal joint includes a fixed end and a movable end. Before holding the universal joint, a mounting hole with a size that matches the fixed end of the universal joint is opened on the gearbox cover 1. The fixed end of the universal joint is fixed in the mounting hole. The movable end of the universal joint is inserted into the fixed end, and a bearing is provided between the fixed and movable ends so that the movable end can rotate freely in the horizontal direction after being connected to the fixed end. When refilling the oil, there is no need to change the direction of the refueling vehicle based on the direction of the top of the refill pipe 8, which reduces the difficulty of operating the device.

[0028] Among them, the position of the oil filling pipe 8 corresponds to the locking plate 2. When thieves attempt to insert an oil stealing tool into the oil filling pipe 8 to steal the lubricating oil in the reducer, the inserted oil stealing tool will be released from the locking plate 2, and the locking plate 2 prevents the oil stealing tool from being inserted, thereby playing a further anti-theft function.

[0029] In order to save materials and reduce the manufacturing cost of the device, the locking plate 2 can be processed into an X shape. After the locking plate 2 is fixed to the reducer cover 1, the locking plate 2 is rotated 90 degrees so that the four long sides of the X-shaped locking plate 2 extend out of the reducer cover 1 and contact the reducer body for clamping. The X-shaped locking plate 2 can save materials and reduce its own weight, reduce the amount of force that the reducer cover 1 and the screw 3 need to bear, and improve the stability and service life of the device. At this time, when installing the refueling pipe 8, it is necessary to pay attention to the installation position of the refueling pipe 8 and the position of one of the long sides of the rotating locking plate 2. At this time, the locking plate 2 can still catch the refueling pipe 8 from the bottom and prevent the oil theft tool from extending into the reducer through the refueling pipe 8. After the locking piece 2 is processed into an X shape, in order to facilitate the determination of the position of the locking piece 2 in the reduction gear box, magnets can be installed at the ends of the four long sides of the locking piece 2. When the locking piece 2 is rotated 90° under the reduction gear box upper cover 1, the ends of the four long sides of the locking piece 2 are located below the reducer body. The magnets are attracted to the reducer body to generate magnetic force, and further rotation of the locking piece 2 will be prevented by the magnetic force. When the screw 3 is used to drive the locking piece 2 to rotate, it is found that the screw 3 has a force that prevents further rotation, which indicates that the locking piece 2 has been rotated to the locked position, reducing the working difficulty of the device.

[0030] It should be noted that to ensure the cleanliness of the lubricating oil in the reduction gearbox, a filter is usually installed at the bottom of the filler pipe 8. The filter can filter the air flowing in during normal working conditions and the new oil injected during refueling, preventing impurities from entering the reduction gearbox through the filler pipe 8. At the same time, the filter and the lock plate 2 can prevent the insertion of oil theft tools into the filler pipe 8, thus playing a theft prevention role.

[0031] In order to facilitate opening and closing the reduction gear box cover 1, a handle 9 protruding upward is usually provided on the top of the reduction gear box cover 1. After opening the anti-theft box 4 and the lock plate 2, the reduction gear box cover 1 can be opened by directly pulling the handle 9.

[0032] Combine Figures 1 to 2 The following is a detailed description of the steps of the reduction gearbox anti-theft sealing integrated device when it works:

[0033] Step 1: Install the lock plate under the gearbox cover and fix the gearbox cover to the top of the gearbox body.

[0034] Step 2: Turn the screw to rotate the locking plate under the reducer cover to lock the reducer cover. At this time, the locking plate rotates 90 degrees with the screw, and the long end of the locking plate under the reducer extends below the reducer body. Then, turn the nut on the screw to cooperate with the locking plate to clamp the reducer cover, thereby fixing the position of the locking plate. When the reducer cover is lifted without turning the screw, the upper surface of the locking plate will contact the reducer body and drive the reducer cover to maintain its original position, preventing the reducer cover from opening and realizing the anti-theft function.

[0035] Step 3: After snapping the anti-theft box closed, use the remote control to control the remote lock to eject the lock tongue and engage the lock box to seal the anti-theft box. After the remote lock ejects the lock tongue, it extends into the lock box to secure the lock box in place. Until the remote lock retracts the lock tongue, the top cover of the anti-theft box is always locked by the lock tongue and cannot be opened. The top of the screw is protected inside, preventing thieves from turning the screw and lock plate to open the gearbox cover, thus achieving the anti-theft function.

[0036] Step 4. Remove the power supply of the remote control lock to prevent the power supply from being corroded and damaged when working outdoors for a long time.

[0037] Step 5: When refueling is needed, stop the refueling vehicle near the reduction gearbox, turn the refueling pipe toward the refueling vehicle, connect the oil pipe to the refueling pipe, and add new lubricating oil into the reduction gearbox.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
