Applying the technical solution of this embodiment, when disassembling the end cover of the transmitter, the worker holds the handle 30 of the disassembly tool with his hand, and then extends the claw 20 on the body 10 into the hole on the end cover of the transmitter. In the groove, the claw 20 can be reliably engaged with the groove, and then the end cover can be easily removed or installed by turning the handle 30 and applying torque. Since the handle 30 is provided and one end of the handle 30 is connected to the body 10 , a worker can easily apply a larger torque by holding the other end of the handle 30 during operation. When removing the transmitter end cover, the transmitter end cover can be quickly disassembled by applying a large torque, and correspondingly, when the transmitter end cover is installed, it can be quickly and fastened by applying a large torque Securely install the transmitter cover. Therefore, by setting the handle 30, on the one hand, the labor intensity of the staff can be reduced, and the operation efficiency can be improved; Due to the provision of the claw 20, when the transmitter end cover is removed or installed, the claw 20 can be reliably snapped into the groove on the transmitter end cover, thereby preventing the tool from slipping or damaging the end cover, and facilitating Apply torque. Moreover, since the distance between the claw 20 and the axis of the body 10 can be adjusted, the dismounting tool can be used to disassemble the end covers of transmitters of different specifications, which increases the versatility of the dismounting tool.

Specifically, in this embodiment, a sliding slot can be provided on the body 10, and the claw 20 can be slidably arranged in the sliding slot. In this way, the distance between the claw 20 and the axis of the main body 10 can be adjusted by sliding the claw 20 in the slide groove, so as to match the end covers of transmitters of different specifications. After the claw 20 is adjusted to a predetermined position, the position of the claw 20 on the body 10 can be fixed by fasteners, so as to ensure the reliability of the dismounting tool and facilitate the application of torque.

Applying the technical solution of this embodiment, the claw 20 on the body 10 is driven to rotate through the rotation of the handle 30, and the end cover of the transmitter is driven to rotate through the cooperation between the claw 20 and the groove, so that the end cover can be easily and quickly disassembled or installed. cover. In this way, the problem of insufficient torque and time-consuming and labor-intensive direct operation by hand in the prior art is avoided, and the problem of easy slipping or damage to the end cover when operated with a common wrench is also avoided. Therefore, the assembly and disassembly tool provided in this embodiment can facilitate the assembly and disassembly of the end cover of the transmitter, and can ensure the sealing and reliability of the end cover. For example, using the disassembly tool for the calibration and maintenance of Rosemount pressure and liquid level transmitters can achieve convenient and efficient operation at a lower cost, ensuring the normal operation of the equipment and the smooth progress of production.

Specifically, a plurality of jaws 20 of the dismounting tool may be provided, the plurality of jaws 20 are arranged at intervals on the outer peripheral surface of the body 10 , and the centerlines of the plurality of jaws 20 are all located on the same plane. A plurality of claws 20 are arranged in one-to-one correspondence with multiple grooves on the end cover of the transmitter. Setting the centerlines of the multiple claws 20 on the same plane allows multiple claws 20 to be snapped into multiple grooves at the same time. in the slot. When using the disassembly tool, a plurality of claws 20 can be snapped into a groove on the end cover of the transmitter, which can increase the firmness of the disassembly tool and the end cover, and the multiple claws 20 restrict each other to prevent the claws 20 from slipping, so that the end cover can be disassembled more smoothly. After a plurality of claws 20 are set, the structural strength increases, and greater torque can be applied to the end cover through the joint action of multiple claws 20, thereby improving the efficiency of disassembling and assembling the end cover and the sealing performance of the end cover after installation , but also can prolong the service life of disassembly tools.

In this embodiment, the extension line of the centerline of the claws 20 passes through the axis of the body 10 , and the angles between the centerlines of two adjacent claws 20 are equal. By passing the extension line of the center line of the claw 20 through the axis of the body 10, the setting angle of the claw 20 can be matched with the setting angle of the groove on the end cover of the transmitter, so that the claw 20 can be engaged with the groove catch. Setting the angle between the centerlines of two adjacent jaws 20 to be equal can increase the versatility of the disassembly tool, that is, as long as one jaw 20 is snapped into any groove at the correct position, The other claws 20 can be snapped into other corresponding grooves at the same time. In this way, when the transmitter end cover is disassembled, the disassembly tool and the transmitter end cover can have multiple matching positions, thereby facilitating the use of the disassembly tool.

The size of the body 10 in the dismounting tool, the size and number of claws 20 should match the size and number of the end cover of the transmitter and the grooves on the end cover. For example, there are 6 grooves on the end cover of the transmitter, and the angle between the center lines of adjacent grooves is 60 degrees. As shown in FIG. 1 , six claws 20 can be provided correspondingly, and the angle between the centerlines of two adjacent claws 20 is 60 degrees. In this way, the matching of the disassembly tool and the transmitter end cover can be ensured, and multiple matching positions can be provided between the disassembly tool and the transmitter end cover, so that it is convenient to use the disassembly tool to disassemble the transmitter end cover.

As shown in FIG. 1 , the clamping jaw 20 has two parallel clamping surfaces 21 , the two clamping surfaces 21 match the inner surface of the groove on the end cover of the transmitter, and the clamping surfaces 21 are aligned with the axis of the body 10 parallel. The claw 20 and the groove are engaged by the cooperation between the two engaging surfaces 21 on the claw 20 and the inner surface of the groove, so that the end cover of the transmitter can be disassembled using a disassembly tool. In order to facilitate the connection or separation of the claw 20 and the groove while the clamping is firm, a certain gap is set between the claw 20 and the groove, that is, the distance between the two clamping surfaces 21 is set to be less than the groove. The distance between the two inner faces. The specific value of the gap can be set according to the size and processing technology of the groove. In order to facilitate the processing of the claw 20, the claw 20 can be set as a cuboid.

In this embodiment, the body 10 of the dismounting tool can be configured in different structures. For example, the body 10 can be set as a circular plate, and the claw 20 can be connected with the outer peripheral surface of the circular plate, and the handle 30 can be connected with the outer peripheral surface of the circular plate; or the body 10 can be set as a ring, and the claw 20 is connected with the outer peripheral surface of the ring, and the handle 30 is connected with the outer peripheral surface of the ring. Setting the body 10 as a circular plate can increase the structural strength of the device, and the size of the circular plate should match the size of the end cover of the transmitter. Setting the body 10 as a ring can reduce the weight of the device, thereby facilitating the operation of the staff, and the size of the ring should match the size of the transmitter end cover. Wherein, the circular plate can be made of a steel plate, and the ring can be made of a steel pipe, both of which have simple structures and low processing costs.

As shown in FIG. 2 , the body 10 has a first end surface 11 and a second end surface 12 oppositely disposed, the claw 20 is disposed close to the first end surface 11 , and the handle 30 is disposed close to the second end surface 12 . When using the dismounting tool, the first end surface 11 of the body 10 is close to the end cover of the transmitter. Such setting can prevent the handle 30 from interfering with the end cover of the transmitter, and make the claw 20 fit into the groove on the end cover of the transmitter. It is snapped firmly to facilitate the disassembly and assembly of the transmitter end cover.

Preferably, in one embodiment of the present invention, the extension line of the centerline of the handle 30 passes through the axis of the body 10 , and the centerline of the handle 30 is perpendicular to the axis of the body 10 . Such setting is convenient for applying torque, thereby reducing the labor intensity of workers.

Further, the handle 30 of the dismounting tool includes a first rod segment 31 and a second rod segment 32, wherein the first rod segment 31 is connected to the body 10, the second rod segment 32 is connected to the first rod segment 31, and the second rod segment 31 is connected to the body 10. The centerline of the rod section 32 coincides with the centerline of the first rod section 31 . Moreover, the cross-sectional area of the first rod segment 31 decreases gradually from the second rod segment 32 to the direction of the body 10 . In this way, the cross section of the handle 30 close to the body 10 is smaller, thereby preventing the handle of the dismounting tool from interfering with the end cover of the transmitter when the dismounting tool is used. As shown in FIG. 2 , the first rod segment 31 and the second rod segment 32 are of an integral structure, and two inclined surfaces are provided on the second rod segment 32 , and the cross section of the second rod segment 32 can be changed through the two inclined surfaces.

In this embodiment, the handle 30 can be made of 45# carbon steel, and the total length of the handle 30 can be set to 50 mm to 70 mm, and of course can also be set to other values according to the requirement of the applied torque. Wherein, the included angle between the slope on the second rod segment 32 and the axis of the second rod segment 32 can be set at 5 degrees to 15 degrees.

In order to facilitate the use of dismounting tools, the outer peripheral surface of the second rod segment 32 is knurled. When using the assembly and disassembly tool, the worker grasps the second rod section 32 to apply torque to the end cover of the transmitter, which can prevent hand slipping and facilitate the use of the assembly and disassembly tool. Wherein, the depth of the teeth produced by the knurling process can be set at 0.2 to 0.7 mm, and the distance between adjacent teeth can be set at 0.2 to 0.7 mm. In this embodiment, the depth of the teeth is set to 0.5 mm, and the distance between adjacent teeth is set to 0.5 mm.

In order to reduce the manufacturing cost of the dismounting tool, the body 10, the claw 20 and the handle 30 can be processed separately, and then the three can be connected together by welding. This not only ensures the structural strength of the disassembly tool, but also reduces the processing difficulty and material consumption, thereby reducing the manufacturing cost of the disassembly tool. For transmitter end covers of different models or sizes, matching disassembly tools can be manufactured separately, and the size of each structure on the disassembly tool can be set according to the size of the transmitter end cover.

Applying the technical scheme of the utility model, when disassembling the end cover of the transmitter, the staff hold the handle 30 of the disassembly tool with their hands, and then extend the claw 20 on the body 10 into the end cover of the transmitter. In the groove, the claw 20 can be reliably engaged with the groove, and then the end cover can be easily removed or installed by turning the handle 30 and applying torque. Applying torque through the handle 30 can, on the one hand, reduce the labor intensity of workers and improve operating efficiency; on the other hand, it can improve the sealing of the connection of the transmitter end cover, thereby meeting safety requirements such as explosion-proof, and improving the safety of equipment and personnel. Since the claws 20 are provided, and multiple claws 20 can be set, when the transmitter end cover is removed or installed, multiple claws 20 can be reliably snapped into the corresponding grooves on the transmitter end cover center, which prevents the tool from slipping or damaging the end cap, and facilitates torque application. The rotation of the handle 30 drives the claw 20 on the body 10 to rotate, and the cooperation between the claw 20 and the groove drives the end cover of the transmitter to rotate, so that the end cover can be easily and quickly removed or installed. Applying the technical scheme of the utility model, the claw 20 on the body 10 is driven to rotate through the rotation of the handle 30, and the end cover of the transmitter is driven to rotate through the cooperation of the claw 20 and the groove, so that the end cover can be easily and quickly disassembled or installed. cover. In this way, the problem of insufficient torque and time-consuming and labor-intensive direct operation by hand in the prior art is avoided, and the problem of easy slipping or damage to the end cover when operated with a common wrench is also avoided. Therefore, the dismounting tool can facilitate the disassembly and assembly of the end cover of the transmitter, and can ensure the sealing and reliability of the end cover. Moreover, since the distance between the claw 20 and the axis of the body 10 can be adjusted, the dismounting tool can be used to disassemble the end covers of transmitters of different specifications, which increases the versatility of the dismounting tool.
