Description

Technical Field

[0001] The utility model belongs to the technical field of disassembly and assembly tools, and particularly relates to a special tool for an open-type temperature measuring device. Background Art

[0002] A thermal resistor is a commonly used temperature measuring device, which transmits temperature signals to an external digital display or DCS system for monitoring through leads. During the maintenance and overhaul of traditional hot tanks, it is often necessary to disassemble and assemble the thermal resistor. However, some thermal resistors are installed in the grooves of the equipment, with limited space, making the disassembly and assembly process difficult.

[0003] Since the tail of this type of thermal resistor is equipped with a transmission line, it is not suitable to use a traditional hexagonal socket. The solution in the prior art is mainly to use a pair of needle-nose pliers for removal. By clamping the hexagonal head of the thermal resistor with the needle-nose pliers and rotating it, the disassembly and assembly of the thermal resistor can be achieved in a small rotation space within the groove, but there are some problems. First, the use of needle-nose pliers requires certain operating skills and has high requirements for operators. During the use process, the thermal resistor is easily damaged due to incorrect clamping force direction, affecting its service life and measurement accuracy. In addition, if the thermal resistor to be disassembled and assembled is used to measure liquid media, there is a risk of scalding due to the leakage of hot liquid media in the hot tank during the disassembly and assembly process.

[0004] Therefore, designing a disassembly and assembly tool suitable for thermal resistors with leads for temperature measurement in grooves is an urgent problem to be solved currently. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a special tool for an open-type temperature measuring device to solve the problems existing in the prior art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A special tool for an open-type temperature measuring device, including a rotating cylinder, one end of the rotating cylinder is detachably provided with a hexagonal socket, one end of the hexagonal socket is provided with a soft ring, the soft ring is used for pressing on the external position of the open-type temperature measuring device, one side of the rotating cylinder is provided with a rotating disk, the other end of the rotating cylinder is connected with an external joint, and a drainage mechanism is rotatably arranged on the external joint, and the drainage mechanism is used for guiding and discharging the relatively hot liquid introduced into the rotating cylinder.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] This special tool for an open-type temperature measuring device is suitable for disassembling and assembling thermal resistors in a small rotation space within a groove, and is easy to operate, and the thermal resistor is not easily damaged during the whole process.

[0009] This special tool for the opening temperature measuring device can effectively prevent the leakage of liquid medium through the pressure sealing of the soft ring. Under the action of the drainage mechanism, the liquid introduced into the rotating cylinder can be drained downward, avoiding direct splashing onto the hands of workers and the risk of scalding caused by the leakage of hot liquid medium in the hot tank.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0019] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, an embodiment of the utility model provides a special tool for an opening temperature measuring device, which includes a rotating cylinder 1. A hexagonal sleeve 3 is detachably arranged at the left end of the rotating cylinder 1. The set length of the hexagonal sleeve 3 is such that the threaded part of the thermal resistor can be completely screwed out of the thermal tank. The sizes of the hexagonal sleeve 3 are M10, M12, and M14. By installing hexagonal sleeves 3 of different sizes, the disassembly and assembly requirements of thermal resistors of different sizes can be adapted. A soft ring 4 is adhesively bonded to the left end of the hexagonal sleeve 3 with heat-resistant resin glue. The soft ring 4 is in the shape of a flared round cover structure. The material of the soft ring 4 is fluororubber. The size of the soft ring 4 is such that it can slide and be inserted into the groove for installing the thermal resistor in the thermal tank. With such a setting, when the hexagonal sleeve 3 is sleeved on the hexagonal head at the tail of the thermal resistor and the soft ring 4 is pressed against the outer side of the thermal tank, through the pressure sealing of the soft ring 4, the leakage of liquid medium can be effectively prevented; a rotating disk 7 is integrally arranged on the right side of the rotating cylinder 1. The rotating disk 7 is provided for rotating the rotating cylinder 1 and the hexagonal sleeve 3; an external joint 8 is integrally communicated with the right end of the rotating cylinder 1. A drainage mechanism is rotatably arranged on the external joint 8. The drainage mechanism is used for guiding and discharging the relatively hot liquid introduced into the rotating cylinder 1 downward.

[0020] Under the action of the drainage mechanism, the liquid introduced into the rotating cylinder 1 can be discharged downward, avoiding directly splashing onto the hands of workers.

[0021] Refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 6 Referring to Figure 2 , Figure 3 , Figure 4 , and Figure 6 , a joint 2 is integrally communicated with the center position at the right end of the hexagonal sleeve 3. The outer wall of the joint 2 is coated with a fluororubber layer and is tightly inserted into the left end of the rotating cylinder 1. At the right end of the hexagonal sleeve 3 and circumferentially uniformly around the outer edge of the joint 2, insertion posts 5 are integrally arranged. The left end of the rotating cylinder 1 is circumferentially uniformly provided with slots, and a magnetic layer 101 is fixedly arranged in the slots. The magnetic layer 101 adsorbs the insertion posts 5, and the insertion posts 5 slide and are inserted into the inner wall of the magnetic layer 101.

[0022] The joint 2 is tightly inserted and sealed at the left end of the rotating cylinder 1, ensuring the sealing performance at the connection between the rotating cylinder 1 and the hexagonal sleeve 3, and preventing the leakage of hot liquid medium through the connection between the rotating cylinder 1 and the hexagonal sleeve 3. And by sliding the circumferentially arranged insertion posts 5 into the magnetic layer 101 arranged in the circumferentially arranged slots, the rotating cylinder 1 and the hexagonal sleeve 3 are kept rotating synchronously. And this installation method also facilitates the replacement of hexagonal sleeves 3 of different sizes;

[0023] A magnetic ring 6 is fixedly arranged on one side inside the hexagonal sleeve 3. The setting of the magnetic ring 6, when the threaded part of the thermal resistor is screwed out of the thermal tank, adsorbs the head of the thermal resistor through the magnetic ring 6. By pulling this special tool outward, the temperature measuring part of the thermal resistor can be pulled out of the thermal tank.

[0024] Refer to Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 andFigure 7 , the drain mechanism includes a bearing cover 10 rotatably arranged at the right end of the outer joint 8. A sealing bearing 9 is press-fitted and sealed around the right end of the outer joint 8. The bearing cover 10 is press-fitted and sealed around the outer ring of the sealing bearing 9. In this setting, when the bearing cover 10 does not rotate, the outer joint 8 and its connecting components can rotate under the rotational bearing of the sealing bearing 9. Additionally, the setting of the sealing bearing 9 can prevent hot liquid medium from leaking through it when bearing rotation. A circular step groove is formed at the right end of the bearing cover 10. A soft board 11 is bonded in the circular step groove with heat-resistant resin glue. The material of the soft board 11 is fluororubber. A wire-passing enlarged hole 12 is provided at the center of the soft board 11. The size of the wire-passing enlarged hole 12 is such that it can tightly wrap around the outer skin of the transmission line, for passing through and tightly wrapping around the outside of the transmission line of the temperature measuring device;

[0025] When using this tool, the transmission line of the thermal resistor can be passed through the hexagonal sleeve 3, the joint 2, the rotating cylinder 1, the outer joint 8, and the wire-passing enlarged hole 12 in sequence. When rotating the hexagonal sleeve 3 by rotating the rotating disk 7, the transmission line of the thermal resistor can be rotated together.

[0026] A drain pipe 13 is integrally connected to the left side of the bottom of the bearing cover 10. The drain pipe 13 is press-fitted into the discharge hose 14. The length of the hose 14 can be selected according to actual needs, and it is required to ensure that the hose 14 can drain the liquid heat medium to an area away from the workers. A handle 15 is fixed to the bottom of the bearing cover 10 and on the right side of the drain pipe 13 with screws.

[0027] The working principle of this embodiment is as follows:

[0028] When in use, the transmission line of the thermal resistor can be passed through the hexagonal sleeve 3, the joint 2, the rotating cylinder 1, the outer joint 8, and the wire-passing enlarged hole 12 in sequence. Align the hexagonal sleeve 3 with the hexagonal head of the thermal resistor and insert it, and keep the rotating cylinder 1 as perpendicular to the hot tank as possible. Hold the handle 15 and keep pressing the soft ring 4 against the outer wall of the hot tank with force. Rotate the rotating disk 7, and the thermal resistor can be screwed into or out of the hot tank. It is suitable for disassembling and assembling the thermal resistor in a small rotating space in the groove, and the operation is simple. Just align the hexagonal head of the thermal resistor and insert it and rotate, and it is not easy to damage the thermal resistor during the whole process.

[0029] During this process, through the pressure sealing of the soft ring 4, it can effectively prevent the liquid medium from leaking. Under the action of the drain mechanism, the liquid introduced into the rotating cylinder 1 can be drained downward, avoiding directly splashing onto the worker's hand and the risk of scalding caused by the hot liquid medium in the hot tank running, overflowing, or dripping.

[0030] The above is only a preferred embodiment of the present invention, and is not used to limit the protection scope of the present invention.
