[0002] In the prior art, before the inspection and maintenance operations of equipment such as fans, speed reducers, and water pumps, the equipment needs to be powered off first. In order to prevent the equipment such as fans, speed reducers, and water pumps from rotating again due to their own weight or external factors and causing harm to the inspection and maintenance personnel, tools such as wooden boards, iron pipes, brown ropes, and chain hoists are required to fix the coupling. However, the use of tools such as wooden boards, iron pipes, brown ropes, and chain hoists for fixing is not firm and reliable enough, and there is still a risk of injury caused by rotation during the maintenance process, and the use is not convenient enough. Therefore, a safety protection device for inspection and maintenance is proposed to solve the above problems. Content of the Utility Model

[0003] The purpose of the utility model is to provide a safety protection device for inspection and maintenance aiming at the above deficiencies, which can firmly fix the coupling, avoid its rotation during the maintenance process, and is more convenient to use.

[0005] A safety protection device for inspection and maintenance includes a coupling, and is characterized in that: two internally threaded through holes that are symmetric left and right and penetrate through the coupling, stud bolts screwed in the internally threaded through holes, two hexagonal nuts used to tighten the stud bolts on the coupling, a bottom plate arranged below the coupling, two support rods symmetrically arranged left and right on the bottom plate, and a contact block fixed at the top of the support rod, and the contact block abuts against the hexagonal nut.

[0006] Further, a slide rail is welded on the bottom plate, two sliders are slidably connected in the slide rail, an adjusting rod is vertically arranged on the slider, an external thread is arranged on the adjusting rod, and a nut is screwed on the external thread, and the top of the adjusting rod is connected to the support rod.

[0007] Further, a gasket is sleeved on the adjusting rod, and the gasket is arranged on the contact surface between the nut and the slide rail.

[0008] Further, a contact groove is arranged on the contact block, and the shape of the contact groove is adapted to the outer shape of the hexagonal nut.

[0009] The beneficial effects of the utility model are:

[0010] In practical applications, when in use, studs are respectively installed in the internal threaded through holes of the coupling of the device, and hexagonal nuts are tightened with a wrench. Then, the bottom plate is placed below the coupling, and the coupling is fixed by two abutting blocks respectively abutting against the left and right hexagonal nuts, preventing the coupling from rotating during the maintenance process; the utility model can firmly fix the coupling, avoid its rotation during the maintenance process, and is more convenient to use.

[0014] As Figure 1 and Figure 2 shown, a safety protection device for inspection and maintenance includes a coupling 1, characterized in that: two internal threaded through holes that are symmetric left and right and penetrate through the coupling 1, studs 2 screwed in the internal threaded through holes, two hexagonal nuts 3 used to tighten the studs 2 on the coupling 1, a bottom plate 4 arranged below the coupling 1, two support rods 5 symmetrically arranged left and right on the bottom plate 4, and abutting blocks 6 fixed at the top ends of the support rods 5, and the abutting blocks 6 abut against the hexagonal nuts 3.

[0015] When in use, studs 2 are respectively installed in the internal threaded through holes of the coupling 1 of the device, and hexagonal nuts 3 are tightened with a wrench. Then, the bottom plate 4 is placed below the coupling 1, and the coupling 1 is fixed by two abutting blocks 6 respectively abutting against the left and right hexagonal nuts 3, preventing the coupling 1 from rotating during the maintenance process; the utility model can firmly fix the coupling 1, avoid its rotation during the maintenance process, and is more convenient to use.

[0016] As Figure 1 and Figure 2As shown, a slide rail 7 is welded on the bottom plate 4. Two sliders 8 are slidably connected in the slide rail 7. An adjusting rod 9 is vertically arranged on the slider 8. An external thread 91 is arranged on the adjusting rod 9. A nut 10 is screwed on the external thread 91. The top end of the adjusting rod 9 is connected to a support rod 5. In this embodiment, by providing the slide rail 7, the slider 8, the adjusting rod 9 and the nut 10, the distance between the two support rods 5 can be adjusted, and the inspection and maintenance safety protection device is suitable for being fixedly used with different couplings 1.
