Description

Technical Field

[0001] This utility model relates to the field of fire protection devices, and in particular to a fire-fighting interface torque detection device. Background Technology

[0002] A fire hydrant is a fixed fire-fighting facility whose main function is to control combustibles, isolate oxidizers, and eliminate ignition sources. Both the fire hydrant and the hose are equipped with fire hose couplings (consisting of upper and lower couplings). These couplings connect the fire hydrant and hose, allowing for direct water spraying to extinguish the fire.

[0003] Because fire hydrants are subjected to a certain amount of water pressure during opening and closing, the appropriate torque value when connecting the fire hose's fire hose coupling to the hydrant's coupling significantly impacts the hydrant's safe operation. Therefore, a torque testing device is needed to inspect the fire hose coupling. This device offers high accuracy and stability for measuring the torque value of the coupling, making it an indispensable testing instrument in the production process. However, existing torque testing devices are inconvenient to operate and inefficient; therefore, a new torque testing device for fire hose couplings is needed. Utility Model Content

Detailed Implementation

[0027] like Figure 1-2As shown, a fire-fighting interface torque detection device includes a workbench 10, a control panel 20, and a clamping mechanism 30. The control panel 20 and the clamping mechanism 30 are respectively mounted on the workbench 10, and the control panel 20 is connected to the clamping mechanism 30.

The clamping mechanism 30 includes a clamping platform 1, a slider 2 slidably connected to the clamping platform 1, a clamping post 3 mounted on the slider 2, a torque test sensor 4 and a circuit board for receiving signals from the torque test sensor 4 mounted on the clamping post 3, and a rubber collar 5 for attaching the sensor and the circuit board to the clamping post 3. A handheld component 6 for sliding the slider 2 is provided on one side of the clamping platform 1. The relative position between the clamping columns 3 can be adjusted by sliding the slider 2 inward or outward simultaneously, which can accommodate fire-fighting interfaces of different sizes. At the same time, it can control the tightness between the rubber collar 5 on the clamping column 3 and the lower fire-fighting interface. When the upper fire-fighting interface is twisted, the required clamping force between the lower fire-fighting interface and the rubber collar is transmitted to the torque test sensor, making the obtained test data more accurate.

[0028] like Figure 3 As shown, a central hole 11 is provided at the center of the top of the clamping platform 1, and a cylindrical hole 12 is provided below the central hole 11.

The secondary tooth 19 is connected to the handheld component 6. The other end of the handheld component 6 can be connected to the output end of a motor, and its rotation can be controlled by the motor. By rotating the handheld component 6, the handheld component 6 drives the secondary tooth 19 to rotate, causing the gear ring 17 to rotate with the secondary tooth 19, thereby causing the slider 2 to slide inward or outward simultaneously.

[0029] In an embodiment of this utility model, the clamping platform 1 is provided with four sliding grooves 14, the slider 2 is slidably connected in the sliding groove 13, the lower part of the sliding groove 13 near the middle position is connected to the cylindrical hole 12, the outer wall of the clamping platform 1 is provided with a clamping platform hole 15, the clamping platform hole 15 is used to install the auxiliary tooth, the bottom of the clamping platform 1 is provided with a screw hole 16, the screw hole 16 is used to connect the screw, the screw hole 16 is connected to the clamping platform hole 15, so that one end of the screw can extend to the clamping platform hole 15.

[0030] like Figure 4 As shown, the cylindrical tube 13 is located on the upper part of the inner side of the cylindrical tube hole 12. The outer wall of the cylindrical tube 13 is provided with a small cylindrical hole 131 for setting a small cylinder with a secondary tooth. The bottom of the cylindrical tube 13 is provided with a screw hole 7 for connecting to the base plate by screws, so as to make the device stable.

[0031] like Figure 5-6 As shown, the gear ring 17 includes a large bevel gear 171, which meshes with a secondary gear 19, causing the large bevel gear 171 to rotate following the secondary gear 19. The top of the large bevel gear 171 is provided with a planar thread 172. The top of the slider 2 is provided with several threaded holes 21, and the lower end of the clamping post 3 is threaded into the threaded holes 21. The clamping post 3 can be connected to different threaded holes 21 to adjust the relative position between the clamping posts 3. The bottom end of the slider 2 is provided with several arc-shaped strips 22, which are slidably connected to the planar thread 171 of the gear ring 17. When the secondary gear 19 drives the large bevel gear 171 to rotate, the planar thread 172 of the upper gear ring rotates, and the slider 2 can slide inwards or outwards simultaneously, thereby changing the relative position between the clamping posts 3 connected to the slider 2.

[0032] like Figure 7-8 As shown, a base plate 18 is provided below the gear ring 14, and the base plate 18 is located in the lower part inside the cylindrical hole 17. The base plate 18 includes a bottom plate 181 and a hollow cylinder 182. The bottom plate 181 is connected to the hollow cylinder 182. The bottom of the bottom plate 181 is provided with a plurality of screw holes 7. Screws 8 are provided to pass through the screw holes 7 of the bottom plate 181 and the cylindrical cylinder 13 in sequence to connect the base plate 18 to the cylindrical cylinder 13. A plurality of U-shaped grooves 183 are provided on the hollow cylinder 182. The auxiliary gear 19 includes a small bevel gear 191, which extends out of the clamping platform hole 15 and meshes with a large bevel gear 171 in a U-shaped groove 183.

The other end of the small bevel gear 191 is connected to a large cylinder 193. An annular groove 194 is formed between the large cylinder 193 and the small bevel gear 191. A screw 9 is provided, passing through a screw hole 16 and extending into the annular groove 194, so that the upper part of the screw is engaged with the auxiliary gear to limit its position. One end of the large cylinder 193 is connected to the handheld component 6.

[0033] Working principle

[0034] Rotating the handheld component 6 forward causes the auxiliary gear 19 to rotate, which in turn causes the gear ring 17 to rotate. The rotation of the gear ring 17 causes the slider 2 to slide towards the center, clamping the rubber collar 5 on the clamping column 3 with the lower fire interface. When the upper fire interface is twisted, the clamping force required between the lower fire interface and the rubber collar is transmitted to the torque test sensor 4, and the data is displayed on the control panel. Rotating the handheld component 6 in the reverse direction causes the auxiliary gear 19 to rotate in the opposite direction, which in turn causes the gear ring 17 to rotate in the opposite direction. The gear ring 17 then causes the slider 2 to slide outward, releasing the rubber collar 5 on the clamping column 3 from the lower fire interface, allowing the fire interface to be removed.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
