TECHNICAL FIELD

[0001] The present application relates to the field of tools for underwater ROV, in particular to an underwater high-precision intelligent torque wrench. BACKGROUND

[0002] At present, important equipment such as Christmas tree, MQC, manifold, SCM in underwater production system needs to use ISO13628-8 standard rotary butt joint interface for operation, which can be used for locking, releasing and unloading of Christmas tree valve, clamp and underwater control module. The interface is a square drive rod surrounded by a barrel-shaped shell, which is fixed by bolts or directly welded to the underwater system hydraulic panel, or can be independent, and even designed as an integral part of the underwater structure. Its structure is shown in the drawings, and the rotary butt joint interface in the underwater production system can be arranged horizontally or vertically.

[0003] As shown in the prior art, Figure 1 A rotary torque socket 200 is provided on the rotary interface 100 for exposing the end effector 300. Two lock holes 400 are provided on the rotary interface 100. The ROV torque wrench can be fixed on the equipment with the rotary torque socket 200 through the locking mechanism. The ROV torque wrench provides hydraulic power or electric driving power to control the torque wrench to drive the end effector 300 to rotate to complete the installation, rotation and removal tasks.

[0004] As shown in the prior art, Figure 1 The rotary interface on the underwater production system in the prior art has a rotary torque socket for exposing the end effector. The common torque wrench is provided with a torque output connector, which is provided with a connecting port matched with the end effector. The torque wrench is provided with a hydraulic cylinder for driving the torque output connector to rotate, which can drive the end effector to rotate synchronously.

[0005] However, the existing driving method has a long torque response time, which is time-consuming and laborious. In actual use, in order to save operation cost, the number of diving should be reduced as much as possible, and the response speed of the torque wrench should be improved, which needs to be improved. CONTENT OF THE INVENTION

[0006] In order to improve the torque response speed of the torque wrench, the present application provides an underwater high-precision intelligent torque wrench.

[0007] The underwater high-precision intelligent torque wrench provided by the present application adopts the following technical scheme:

[0008] An underwater high-precision intelligent torque wrench mainly includes a housing and a torque output connector. The torque output connector is installed on the housing. A hydraulic motor, a torque sensor, a torque multiplier, and an encoder are installed inside the housing. The two ends of the torque multiplier are respectively connected to the torque sensor and the torque output connector through couplings. The output shaft end of the torque output connector is connected to the torque sensor through a coupling.

[0009] A display and control unit is installed on the housing, and the display and control unit is electrically connected to the encoder and the torque sensor.

[0010] A locking mechanism for locking the torque output connector and the rotary interface is installed between the housing and the torque output connector.

[0011] By adopting the above technical solution, in the actual use of the torque wrench, the operator can insert the torque output connector of the torque wrench into the rotary torque port of the underwater ROV equipment's rotary interface, connecting the connector's connection port to the end effector in the rotary interface. Subsequently, the hydraulic motor drives the torque output connector to rotate and output torque. With the cooperation of a torque multiplier connected to the hydraulic motor, the torque output of the hydraulic motor can be increased, allowing the torque output connector to reach the preset torque, meeting the torque output requirements. A torque sensor installed between the torque multiplier and the hydraulic motor can detect the torque output of the torque wrench in real time and display it through the display and control unit. By using the torque multiplier and hydraulic motor in combination, the hydraulic motor's fast torque response, combined with the torque multiplier, ensures that the output torque reaches the required value while shortening the output torque response time, improving the torque wrench's response efficiency and overall working efficiency. Meanwhile, the locking mechanism between the housing and the torque output connector can lock the torque output connector inside the rotary interface when the torque wrench is in use, ensuring a stable connection between the torque output connector and the rotary interface during torque output and preventing interference from complex environments such as ocean currents on the operation of the torque wrench.

[0012] Preferably, the torque output connector includes a housing, and the locking mechanism includes two locking seats, each of which is fixedly mounted with two connecting plates, and a sliding groove is formed between the two connecting plates;

[0013] Both of the aforementioned slides are equipped with locking elements, and the housing is equipped with a drive mechanism for opening or closing the two locking elements.

[0014] By adopting the above technical solution, the two locking parts on the locking seat are opened by the drive mechanism, so that the locking parts are inserted and limited in the lock hole of the rotary interface, thereby realizing the locking between the torque output connector and the rotary interface; when the use is over, the two locking parts are returned by the drive mechanism, so that the two locking parts are retracted and withdrawn from the two lock holes, thereby unlocking the torque output connector and the rotary interface.

[0015] Preferably, both connecting plates are provided with oblong holes, and the two oblong holes are arranged opposite to each other. The direction of the two oblong holes is perpendicular to the radial direction of the outer shell. The locking member is provided with mounting holes, and bolt pins are inserted into the mounting holes. The rods of the bolt pins extending out of the mounting holes are respectively slidably disposed in the two oblong holes.

[0016] The drive mechanism includes two hydraulic cylinders mounted on the housing. Each hydraulic cylinder includes a pull rod. Each of the two locking seats has a through hole for the pull rod to pass through. The ends of the two pull rods are rotatably connected to the ends of the locking member by pins.

[0017] By adopting the above technical solution, when it is necessary to lock the torque output connector and the rotary interface, the hydraulic cylinder pressurizes, causing the cylinder rod to move towards the rotary interface, causing the locking member to rotate away from the slide groove, so that the locking member opens and extends into the lock hole of the rotary interface, completing the locking between the torque output connector and the rotary interface; when the torque tool is used up, the hydraulic cylinder releases the hydraulic pressure, and the cylinder rod moves away from the rotary interface, causing the locking member to rotate and return to the slide groove, so that the locking member slides out of the lock hole of the rotary interface, making it easy to retract the torque output tool.

[0018] Preferably, the locking seat includes a mounting plate, and both connecting plates are fixedly mounted on the mounting plate. The mounting plates are fixedly mounted on the housing by screws, and the two locking seats are symmetrically arranged about the housing.

[0019] Preferably, the display and control unit includes an external control compartment, which is mounted on the end of the housing away from the torque output connector; and:

[0020] The main control circuit is installed inside the external control compartment and is electrically connected to the encoder and the torque sensor.

[0021] The display is mounted on the external control cabin and is connected to the signal output terminal of the torque sensor.

[0022] The battery is fixedly installed inside the external control compartment and electrically connected to the display, the main control circuit, and the torque sensor.

[0023] By adopting the above technical solution, the battery can power the display, main control circuit and torque sensor. The display can receive and display the torque value measured by the torque sensor in real time, so that the user can keep track of the torque output of the torque wrench in real time.

[0024] In summary, the underwater high-precision intelligent torque wrench of this application has at least one of the following beneficial technical effects:

[0025] 1. By using a torque multiplier in conjunction with a hydraulic motor, the hydraulic motor can output torque with a fast response. When combined with a torque multiplier, the output torque can be guaranteed to reach the required value while shortening the response time of the output torque, thereby improving the response efficiency of the torque wrench and increasing its working efficiency.

[0026] 2. When it is necessary to lock the torque output connector and the rotary interface, the hydraulic cylinder pressurizes, causing the cylinder rod to move towards the rotary interface, which in turn causes the locking element to rotate away from the slide groove. This allows the locking element to open and extend into the lock hole of the rotary interface, thus locking the torque output connector and the rotary interface. When the torque tool is no longer in use, the hydraulic cylinder releases the hydraulic pressure, and the cylinder rod moves away from the rotary interface, causing the locking element to rotate and return to the slide groove. This allows the locking element to slide out of the lock hole of the rotary interface, making it easy to retract the torque output tool. Attached Figure Description

Detailed Implementation

[0031] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0032] Example 1

[0033] This application discloses an underwater high-precision intelligent torque wrench. (Refer to...) Figures 1-3 It mainly includes a housing 1 and a torque output connector 2. The torque output connector 2 is mounted on the housing 1. The housing 1 houses a hydraulic motor 11, a torque sensor 12, a torque multiplier 13, and an encoder. The two ends of the torque multiplier 13 are connected to the torque sensor 12 and the torque output connector 2 respectively via couplings. The output shaft end of the torque output connector 2 is connected to the torque sensor 12 via a coupling. A display and control unit 3 is mounted on the housing 1. The display and control unit 3 is electrically connected to the encoder and the torque sensor 12. A locking mechanism 4 for locking the torque output connector 2 and the rotary interface 100 is installed between the housing 1 and the torque output connector 2.

[0034] In actual use of the torque wrench, the operator can insert the torque output connector 2 on the torque wrench into the rotation torque port 200 of the rotation interface 100 of the underwater ROV equipment, and connect the connection port inside the torque output connector 2 to the end effector 300 in the rotation interface 100. Subsequently, the torque output connector 2 can be driven to rotate by the hydraulic motor 11 to output torque. With the cooperation of the torque multiplier 13 connected to the hydraulic motor 11, the torque output by the hydraulic motor 11 can be increased, so that the torque output connector 2 reaches the preset torque and meets the torque output requirements. The torque output torque of the torque wrench can be detected in real time by the torque sensor 12 installed between the torque multiplier 13 and the hydraulic motor 11, and displayed by the display and control unit 3.

[0035] By using the torque multiplier 13 in conjunction with the hydraulic motor 11, the hydraulic motor 11 can output torque with a fast response. When used in conjunction with the torque multiplier 13, it can ensure that the output torque reaches the required value while shortening the response time of the output torque, thereby improving the response efficiency of the torque wrench and increasing the working efficiency of the torque wrench.

[0036] Meanwhile, the locking mechanism 4 between the housing 1 and the torque output connector 2 can lock the torque output connector 2 inside the rotary interface 100 when the torque wrench is in use, ensuring a stable connection between the torque output connector 2 and the rotary interface 100 during torque output, and preventing interference from complex environments such as ocean currents on the operation of the torque wrench.

[0037] Reference Figure 2 and Figure 3 The torque output connector 2 includes a housing 21, and the locking mechanism 4 includes two locking seats 41. Two connecting plates 42 are fixedly installed on each locking seat 41, and a sliding groove is formed between the two connecting plates 42. Locking elements are installed in both sliding grooves, and a drive mechanism for driving the two locking elements to open or close is installed on the housing 1.

[0038] The two locking members on the locking seat 41 are opened by the drive mechanism, so that the locking members are inserted into the lock hole 400 of the rotary interface 100, thereby locking the torque output connector 2 and the rotary interface 100. When the use is finished, the two locking members are returned by the drive mechanism, so that the two locking members are retracted and withdrawn from the two lock holes 400, thereby unlocking the torque output connector 2 and the rotary interface 100.

[0039] Reference Figure 3 Both connecting plates 42 are provided with waist-shaped holes 43 for locking; 44, and the two waist-shaped holes 43 are arranged opposite to each other, and the direction of the two waist-shaped holes 43 is perpendicular to the radial direction of the outer casing 21. The locking member is provided with a mounting hole, and a bolt pin 45 is inserted into the mounting hole. The rods of the bolt pin 45 extending out of the mounting hole are respectively slidably disposed in the two waist-shaped holes 43 for locking; 44. The driving mechanism includes two hydraulic cylinders 46 mounted on the housing 1. Both hydraulic cylinders 46 include a pull rod 48. The two locking seats 41 are respectively provided with rod holes 47 for the pull rod 48 to pass through. The ends of the two pull rods 48 are rotatably connected to the ends of the locking members by pins.

[0040] When it is necessary to lock the torque output connector 2 and the rotary interface 100, the hydraulic cylinder pressurizes, causing the cylinder rod 48 to move towards the rotary interface 100, causing the locking member to rotate away from the slide groove, so that the locking member opens and extends into the locking hole 400 of the rotary interface 100, thus completing the locking between the torque output connector 2 and the rotary interface 100; when the torque tool is used up, the hydraulic cylinder releases the hydraulic pressure, and the cylinder rod 48 moves away from the rotary interface 100, causing the locking member to rotate and return to the slide groove, so that the locking member slides out of the locking hole 400 of the rotary interface 100, making it easy to retract the torque output tool.

[0041] Reference Figure 3 The locking seat 41 includes a mounting plate 49, and two connecting plates 42 are fixedly mounted on the mounting plate 49. The mounting plates 49 are fixedly mounted on the outer casing 21 by screws, and the two locking seats 41 are symmetrically arranged about the outer casing 21. In this embodiment, the display and control unit 3 includes an external control compartment 31, which is mounted on the end of the housing 1 away from the torque output connector 2; and: a main control circuit, installed in the external control compartment 31 and electrically connected to the encoder and torque sensor 12; a display 32, installed on the external control compartment 31 and signal-connected to the signal output terminal of the torque sensor 12; and a battery 33, fixedly installed in the external control compartment 31 and electrically connected to the display 32, the main control circuit, and the torque sensor 12.

[0042] Battery 33 provides power to display 32, main control circuit and torque sensor 12. Display 32 can receive and display the torque value measured by torque sensor 12 in real time, so that users can keep track of the torque output of torque wrench in real time.

[0043] The implementation principle of an underwater high-precision intelligent torque wrench according to this application embodiment is as follows: In actual use of the torque wrench, the operator can insert the torque output connector 2 of the torque wrench into the rotary interface 100 of the underwater ROV equipment, and connect the connection port inside the torque output connector 2 to the end effector 300 in the rotary interface 100; subsequently, the torque output connector 2 can be driven to rotate by the hydraulic motor 11 to output torque. Through the cooperation of the torque multiplier 13 connected to the hydraulic motor 11, the torque output of the hydraulic motor 11 can be increased, so that the torque output connector 2 reaches the preset torque and meets the torque output requirements; through the torque sensor 12 installed between the torque multiplier 13 and the hydraulic motor 11, the torque output of the torque wrench can be detected in real time and displayed through the display and control unit 3. By using the torque multiplier 13 and the hydraulic motor 11 together, because the hydraulic motor 11 outputs torque with fast response, combined with the torque multiplier 13, it can ensure that the output torque reaches the required value while shortening the response time of the output torque, improving the response efficiency of the torque wrench, and improving the working efficiency of the torque wrench. When it is necessary to lock the torque output connector 2 and the rotary interface 100, the hydraulic cylinder pressurizes, causing the cylinder rod 48 to move towards the rotary interface 100, causing the locking member to rotate away from the slide groove, so that the locking member opens and extends into the locking hole 400 of the rotary interface 100, thus completing the locking between the torque output connector 2 and the rotary interface 100; when the torque tool is used up, the hydraulic cylinder releases the hydraulic pressure, and the cylinder rod 48 moves away from the rotary interface 100, causing the locking member to rotate and return to the slide groove, so that the locking member slides out of the locking hole 400 of the rotary interface 100, making it easy to retract the torque output tool.

[0044] Example 2

[0045] In this embodiment, the display and control unit 3 is externally connected to the outer side of the torque wrench housing 1 and is installed separately from the torque wrench.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
