Description

Technical Field

[0001] The utility model relates to the technical field of chemical production equipment, and particularly relates to an adjustable pressure gauge fastening device. Background Technique

[0002] A pressure gauge is a pressure monitoring device widely used in large chemical enterprises, mainly used for pressure detection of pipelines and containers.

[0003] In the existing installation process of pressure gauges, generally, workers prepare tools such as fixing rods and fixing rings according to experience to fix the pressure gauge at a convenient observation position. However, in the existing technology, when fastening the pressure gauge, it is generally designed separately according to the sizes of the pressure gauge and the pipeline, with poor universality. For non-standard pipelines, it is easy to cause the problem that the pressure gauge is not tightly fixed. If the pressure gauge shakes and cannot be fixed in time, it is extremely easy to cause damage to the pressure gauge or inaccurate values, or even leakage of the medium at this place.

[0004] In addition, in the existing technology, the pressure gauge is generally fixed by a fixing rod or a fixing ring. Once the position is determined, it cannot be adjusted or changed. On the one hand, it causes inconvenience in the installation process. On the other hand, it limits the position of the pressure gauge and is easy to cause the pressure gauge to be not easily observable. Content of the Utility Model

[0005] To solve the deficiencies of the existing technology, the utility model provides an adjustable pressure gauge fastening device, including: a main pipeline clamp, which is locked by a first set screw. A vertical support column is arranged on the outer surface of one side of the main pipeline clamp along the vertical and perpendicular direction. A support column sliding sleeve is slidably sleeved on the vertical support column, and a second set screw is arranged on the side wall of the support column sliding sleeve. A horizontal support column is fixed on the side wall of the support column sliding sleeve on the opposite side of the second set screw, and a pressure gauge pipe clamp is fixed at the end of the horizontal support column. The pressure gauge pipe clamp is locked by a third set screw, and a fourth set screw for fixing the pressure gauge is arranged on the side wall.

[0006] Furthermore, the horizontal support column is a telescopic rod structure with adjustable length, including a sleeve fixed to the support column sliding sleeve and a sliding rod inserted into the sleeve and slidably connected to the sleeve. The sliding rod is fixed with a pressure gauge pipe clamp at the end.

[0007] Furthermore, an external thread is arranged on the outer wall of the sleeve close to the sliding rod, and the sleeve locks or unlocks the sliding rod through a locking sleeve screwed to the external thread.

[0008] Furthermore, the locking sleeve includes a bearing with an inner diameter of the inner ring larger than the diameter of the sliding rod. The bearing includes a bearing outer ring and a bearing inner ring rotatably connected through balls or rollers. A pressing ring with a right-angled trapezoid cross-section is arranged at the outer edge of the end of the sleeve. The inclined surface end of the pressing ring faces the sliding rod.

[0009] The outer bearing ring extends towards the outer wall of the sleeve relative to the inner bearing ring, and a bearing thread screwed to the external thread is provided at a position corresponding to the external thread on the inner wall of the outer bearing ring.

[0010] The inner bearing ring is connected with a connecting block through a spring. The connecting block is inserted between the pressing ring and the sliding rod, and an inclined surface matching the pressing ring is provided at one end facing the pressing ring. One end of the connecting block facing the sliding rod matches the outer surface of the sliding rod.

[0011] Further, several pulleys are rotatably connected to one end of the connecting block facing the pressing ring.

[0012] Further, a rubber layer matching the outer surface of the sliding rod is connected to one end of the connecting block facing the sliding rod.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. The utility model can, as required, match and fasten the main pipeline within a certain pipe diameter range through the main pipeline clamp, and match and fasten the pressure gauge within a certain diameter range through the pressure gauge pipe clamp, thereby expanding the applicable range of the pressure gauge fastening device.

[0015] 2. Through the arrangement of the vertical support column and the support column sliding sleeve, the utility model enables the pressure gauge to displace and rotate relative to the main pipeline, so that the installation position of the pressure gauge has strong adjustability.

[0022] Embodiment 1

[0023] An adjustable pressure gauge fastening device, as Figure 1 shown, includes: a main pipeline clamp 1, and the main pipeline clamp 1 is locked by a first set screw 2. A vertical support column 3 is provided on the outer surface of one side of the main pipeline clamp 1 along the vertical and perpendicular direction. A support column sliding sleeve 5 is slidably sleeved on the vertical support column 3, and a second set screw 4 is provided on the side wall of the support column sliding sleeve 5. A transverse support column 6 is fixed on the side wall of the support column sliding sleeve 5 on the opposite side of the second set screw 4, and a pressure gauge pipe clamp 7 is fixed at the end of the transverse support column 6. The pressure gauge pipe clamp 7 is locked by a third set screw 8, and a fourth set screw 9 for fixing the pressure gauge is provided on the side wall.

[0024] The usage process of this device is as follows: First, the main pipeline clamp 1 is clamped on the outer wall of the target position of the main pipeline, and then by tightening the first set screw 2, the main pipeline clamp 1 is locked, thereby fixing the relative position with the main pipeline. Then, by sliding the support column sliding sleeve 5, the spatial position of the pressure gauge pipe clamp 7 is adjusted to the target appropriate position, and by tightening the second set screw 4, the support column sliding sleeve 5 is fastened on the vertical support column 3 through friction. Finally, the lower end of the pressure gauge or the support column of the pressure gauge is inserted into the pressure gauge pipe clamp 7, and the third set screw 8 is tightened to make the pressure gauge pipe clamp 7 clamp the pressure gauge, and the pressure gauge is further fastened by tightening the fourth set screw 9.

[0025] The present utility model can match and fasten the main pipeline within a certain pipe diameter range through the main pipeline clamp 1 as needed, and match and fasten the pressure gauge within a certain diameter range through the pressure gauge pipe clamp 7, thereby expanding the applicable range of the pressure gauge fastening device.

[0026] Through the setting of the vertical support column 3 and the support column sliding sleeve 5, the present utility model enables the pressure gauge to be displaced and rotated relative to the main pipeline, so that the installation position of the pressure gauge has strong adjustability.

[0027] Embodiment 2

[0028] The adjustable pressure gauge fastening device based on Embodiment 1, as Figure 2 and Figure 3 shown, the lateral support column 6 is a telescopic rod structure with adjustable length, including a sleeve 601 fixed to the support column sliding sleeve 5 and a sliding rod 602 inserted into the inside of the sleeve 601 and slidably connected to the sleeve 601. The end of the sliding rod 602 is fixed with a pressure gauge pipe clamp 7.

[0029] Compared with a fixed rod, the telescopic rod structure with adjustable length can increase a degree of freedom for adjusting the spatial position of the pressure gauge, further improving the selectivity of the installation position of the pressure gauge.

[0030] Embodiment 3

[0031] The adjustable pressure gauge fastening device based on Embodiment 2, as Figure 3 shown, the outer wall of the sleeve 601 close to the sliding rod 602 is provided with an external thread 6011, and the sleeve 601 locks or unlocks the sliding rod 602 through a locking sleeve 603 screwed to the external thread 6011.

[0032] The locking sleeve 603 includes a bearing with an inner ring inner diameter larger than the diameter of the sliding rod 602. The bearing includes a bearing outer ring 6031 and a bearing inner ring 6032 rotatably connected through balls or rollers. The outer edge of the end of the sleeve 601 is provided with a pressure ring 6012 with a right-angled trapezoid cross-section. The inclined surface end of the pressure ring 6012 faces the sliding rod 602.

[0033] The bearing outer ring 6031 extends towards the outer wall of the sleeve 601 relative to the bearing inner ring 6032, and a bearing thread 6037 screwed to the external thread 6011 is provided at a position corresponding to the external thread 6011 on the inner wall of the bearing outer ring 6031.

[0034] The bearing inner ring 6032 is connected with a connecting block 6034 through a spring 6033. The connecting block 6034 is inserted between the pressure ring 6012 and the sliding rod 602, and an inclined surface matching the pressure ring 6012 is provided at one end facing the pressure ring 6012. One end of the connecting block 6034 facing the sliding rod 602 matches the outer surface of the sliding rod 602.

[0035] At this time, rotate the bearing outer ring 6031, so that the locking sleeve 603 moves closer to or away from the sleeve 601 along the axis of the sleeve 601 relative to the sleeve 601 under the limitation of the screwed external thread 6011. When the locking sleeve 603 approaches the sleeve 601, the connecting block 6034 moves towards Figure 3The left movement in [description] causes one end of the connecting block 6034 facing the sliding rod 602 to press against the sliding rod 602 under the action of the inclined surface of the pressing ring 6012, and the sliding rod 602 is locked through friction. When the locking sleeve 603 moves away from the sleeve 601, the connecting block 6034 moves relatively to the right in [description]. Under the action of the spring 6033, the connecting block 6034 retracts inward along the inclined surface of the pressing ring 6012, so that one end of the connecting block 6034 facing the sliding rod 602 is disengaged from pressing against the sliding rod 602, thereby releasing the lock. Figure 3 The right movement in [description] causes the connecting block 6034 to retract inward along the inclined surface of the pressing ring 6012 under the action of the spring 6033, so that one end of the connecting block 6034 facing the sliding rod 602 is disengaged from pressing against the sliding rod 602, thereby releasing the lock.

[0036] According to an embodiment of the present invention, several pulleys 6036 are rotatably connected to one end of the connecting block 6034 facing the pressing ring 6012. This setting can make the sliding of the connecting block 6034 relative to the pressing ring 6012 smoother and reduce sliding friction.

[0037] According to an embodiment of the present invention, in order to make the force balance when the connecting block 6034 presses against the sliding rod 602, a connecting block 6034 can be connected by a spring 6033 at the opposite side or the equilateral triangle position or the square position or the regular pentagon position or other regular polygon positions of the inner ring 6032 of the bearing.

[0038] According to an embodiment of the present invention, a rubber layer 6035 matching the outer surface of the sliding rod 602 is connected to one end of the connecting block 6034 facing the sliding rod 602. This setting can increase the friction between the connecting block 6034 and the sliding rod 602 through the rubber layer 6035 and improve the fastening of the friction lock between the sliding rod 602 and the sleeve 601.

[0039] Inspired by the above ideal embodiment of the present invention, through the above description, relevant workers can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
