Technical Field

[0001] The utility model relates to the technical field of gas relay detection, in particular to a gas relay detection device. Background Art

[0002] A gas relay is a device that uses changes in gas pressure or density for control and protection. It is commonly used in power systems, petrochemicals, and other fields. It primarily consists of a sensor, actuator, and control system. The sensor detects changes in gas pressure or density and transmits a signal to the control system. The control system then determines whether to activate the actuator based on the received signal to implement the corresponding control and protection functions.

[0003] Gas relays require visual inspection during the production phase. However, the existing inspection method requires inspectors to manually carry the gas relays for visual inspection. Due to the heavy weight of the gas relays, the operator will suffer from physical fatigue after carrying them for a long time, which reduces the inspection speed of the gas relays and affects production efficiency.

[0004] For this purpose, a gas relay detection device is specially proposed. Utility Model Content

To achieve the above-mentioned purpose, the present utility model provides the following technical solutions: A gas relay detection device, comprising a base, a bracket welded at each of the four corners on the top of the base, a top plate welded on the top of the bracket, a driving structure installed on one side of the base and the top plate, a second double-threaded screw and a first double-threaded screw installed inside the base and the top plate through bearings, a slide is provided on the outer sides of both ends of the second double-threaded screw and the first double-threaded screw through a threaded engagement sleeve, a splint is installed on one side of the slide through a rotating shaft, a rubber anti-slip pad is fixed on one side of the splint, a first motor is fixed on one side of the slide by bolts, an electric telescopic rod is fixed on the top of the base by bolts, a bottom plate is welded on the top of the electric telescopic rod, and a detection platform is rotatably installed on the top of the bottom plate.

[0011] Compared with the prior art, the present invention provides a gas relay detection device with the following beneficial effects:

[0012] When performing an appearance inspection on a gas relay, the gas relay can be placed on top of the inspection table first, and then the gas relay can be rotated by rotating the inspection table, so that the inspector can perform an appearance inspection on multiple sides of the gas relay.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 1: A bracket 4 is welded at each of the four corners on the top of the base 1, and a top plate 9 is welded on the top of the bracket 4. A driving structure 13 is installed on one side of the base 1 and the top plate 9. The second double-threaded rod 15 and the first double-threaded rod 12 are installed inside the base 1 and the top plate 9 through bearings respectively. A slide plate 7 is provided on the outer sides of both ends of the second double-threaded rod 15 and the first double-threaded rod 12 through a threaded engagement sleeve. A splint 8 is installed on one side of the slide plate 7 through a rotating shaft 5. A rubber anti-slip pad 11 is fixed to one side of the splint 8. A first motor 6 is fixed to one side of the slide plate 7 by bolts. An electric telescopic rod 2 is fixed to the top of the base 1 by bolts. A bottom plate 14 is welded on the top of the electric telescopic rod 2. A detection table 10 is rotatably installed on the top of the bottom plate 14. The output end of the first motor 6 passes through and extends out of the interior of the slide plate 7, and the output end of the first motor 6 is fixedly connected to one end of the rotating shaft 5.

[0020] Specifically, such as Figure 1 、 Figure 2 and Figure 3As shown, since an electric telescopic rod 2 is installed on the top of the base 1, a bottom plate 14 is fixed to the output end of the electric telescopic rod 2, and a test platform 10 is rotatably installed on the top of the bottom plate 14, when performing an appearance inspection on the gas relay, the gas relay can be placed on the top of the test platform 10 first, and then the gas relay is driven to rotate by rotating the test platform 10, so as to facilitate the inspection personnel to perform appearance inspection on multiple sides of the gas relay, and then the first double-corrugated screw rod 12 and the second double-corrugated screw rod 15 are driven to rotate synchronously by controlling the driving structure 13. Since the outer sides of the two ends of the first double-corrugated screw rod 12 and the second double-corrugated screw rod 15 are respectively provided with a slide plate 7 through a threaded engagement sleeve, the synchronous rotation of the first double-corrugated screw rod 12 and the second double-corrugated screw rod 15 can drive the two slide plates 7 to slide relative to each other along the installation direction of the first double-corrugated screw rod 12 and the second double-corrugated screw rod 15. Since a splint 8 is installed on one side of the slide plate 7, the two splints 8 can be placed on the test platform 10 through the relative sliding of the two slide plates 7. The two sides of the gas relay above are clamped. Since a rubber anti-slip pad 11 is fixed on one side of the splint 8, the rubber anti-slip pad 11 can prevent one side of the splint 8 from directly contacting the gas relay, thereby preventing both sides of the gas relay from being scratched and damaged, thereby affecting its appearance quality. At the same time, the rubber anti-slip pad 11 can increase the friction of clamping the gas relay and improve the stability after clamping. Subsequently, the controller simultaneously controls the output ends of the two first motors 6 to rotate synchronously, which can drive the splint 8 to rotate. The rotation of the splint 8 can drive the clamped gas relay to rotate, thereby facilitating the operator to inspect the appearance part of the gas relay that has not been inspected before and is placed on the test bench 10. This avoids the need for the inspector to manually carry the gas relay for appearance inspection, thereby reducing the work intensity of the inspector and avoiding the physical fatigue of the inspector caused by long-term transportation of the gas relay, thereby stabilizing the speed of gas relay appearance inspection and ensuring production efficiency.

[0021] Example 2: Two supporting slides 801 are welded to one side of the splint 8, and an annular groove 701 is opened on one side of the slide 7. One end of the supporting slide 801 is slidably installed inside the annular groove 701. Three supporting blocks 16 are welded to the outside of the detection platform 10 at equal distances, and one end of the three supporting blocks 16 is welded to the control rod 3. The driving structure 13 includes a shell 1303, and the first sprocket shaft 1302 and the second sprocket shaft 1305, the first double-threaded rod 12 and the second double-threaded rod 15 are respectively installed inside the shell 1303. One end of each extends into the interior of the housing 1303, one end of the first double-threaded rod 12 is fixedly connected to one end of the first sprocket shaft 1302, and one end of the second double-threaded rod 15 is fixedly connected to one end of the second sprocket shaft 1305, a transmission chain 1301 is installed between the first sprocket shaft 1302 and the second sprocket shaft 1305, and a second motor 1304 is fixed to one side of the housing 1303 by bolts, and an output end of the second motor 1304 extends into the interior of the housing 1303 and is fixedly connected to one end of the second sprocket shaft 1305.

[0022] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, since the outer side of the testing platform 10 is connected to the control rod 3 through the support block 16, the control rod 3 can facilitate the testing personnel to rotate and control the testing platform 10. When the splint 8 rotates, the two supporting slide bars 801 fixed on one side of the splint 8 will slide along the opening direction of the annular slide groove 701, thereby ensuring the supporting strength and rotational stability of the splint 8. By controlling the output end of the second motor 1304 to rotate, the second sprocket shaft 1305 and the first sprocket shaft 1302 can be driven to rotate at the same time. Since one end of the second sprocket shaft 1305 and the first sprocket shaft 1302 are respectively connected to one end of the second double-corrugated rod 15 and the first double-corrugated rod 12, the second double-corrugated rod 15 and the second double-corrugated rod 15 can be driven to rotate at the same time by the simultaneous rotation of the second sprocket shaft 1305 and the first sprocket shaft 1302.

[0023] Working principle: The gas relay is then driven to rotate by the rotating inspection table 10, so as to facilitate the inspection personnel to perform appearance inspection on multiple sides of the gas relay. At this time, the bottom of the gas relay cannot be inspected. Therefore, the gas relay is clamped by controlling the relative movement of the two slides 7, and then the gas relay is driven to rotate by the rotation of the output end of the first motor 6. The bottom of the gas relay can be turned over to facilitate the inspection personnel to perform appearance inspection on it, and there is no need for the inspection personnel to manually carry it, thereby ensuring the speed of appearance inspection of the gas relay.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
