Abstract
Description
Technical Field
[0001] This utility model relates to a mechanical signal device, belonging to the field of signal technology. Background Technology
[0002] During shaft construction in mines, the signaling communication between the shaft opening and the hoisting platform underground mostly relies on mine-use explosion-proof and intrinsically safe audible and visual signaling devices. These devices are powered by electricity. If the power supply fails in an emergency, and personnel are in the middle of the shaft in the hoisting bucket, they lose contact with the signalmen at the shaft opening and underground. Once the power supply is restored, the signalmen are unsure whether the bucket is safe to continue hoisting. Given this construction context, this mechanical signaling device was designed and manufactured based on the actual site conditions.
[0003] This utility model proposes a new solution. Utility Model Content

The firing mechanism includes a base plate, a slide rod connected to the top of the base plate, a bell disc movably mounted on the slide rod, a bracket connected to one side of the slide rod, a rotating rod rotatably mounted on the bracket, and a bell hammer located below the bell disc at one end of the rotating rod. The rope winding mechanism includes a mounting frame and a rope-holding drum rotatably mounted on the mounting frame. A pull rope is wound around the rope-holding drum, and one end of the pull rope passes through the end of the rotating rod away from the bell hammer.
[0007] Preferably, a stop block is fixedly connected to the middle of the slide bar, and the bell is located above the stop block.
[0008] Preferably, a top plate is fixedly connected to the top of the slide bar.

[0010] Preferably, a connecting rod is installed on the bracket, and a rotating hole is provided on the rotating rod to cooperate with the connecting rod.
[0011] The beneficial technical effects of this utility model are as follows: According to the mechanical signal device of this utility model,
[0012] 1. During mine shaft construction, it serves as an emergency device that can transmit signals through mechanical operation in the event of signal interruption, thus playing a role in safety protection and reducing the safety risks of hoisting operations;
[0013] 2. In use, the personnel downhole operate the bell hammer by pulling the rope suspended near the well wall, striking the bell plate to produce a sound. The number of sounds is the same as the number of normal hoisting signal points. After hearing it, the wellhead signalman sends a signal to the machine room through the dot device, and the hoisting operation is normal. This device has a simple structure, low investment cost, does not require power supply, has a short processing time, and is easy to operate. It is suitable for all vertical shaft construction processes. Attached Figure Description

[0019] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.
[0020] like Figures 1-4As shown, the mechanical signal device provided in this embodiment includes a firing mechanism 1 and a rope winding mechanism 2. The firing mechanism 1 includes a base plate 3, with a slide rod 4 connected to the top of the base plate 3. A bell disc 5 is movably mounted on the slide rod 4, and a bracket 6 is connected to one side of the slide rod 4. A rotating rod 7 is rotatably mounted on the bracket 6, and one end of the rotating rod 7 is connected to a bell hammer 8 located below the bell disc 5. The rope winding mechanism 2 includes a mounting frame 9 and a rope-holding drum 10 rotatably mounted on the mounting frame 9. A pull rope 11 is wound and connected to the rope-holding drum 10, and one end of the pull rope 11 passes through the end of the rotating rod 7 away from the bell hammer 8. With the setting of the firing mechanism 1 and the rope winding mechanism 2, the personnel downhole operate the bell hammer 8 by pulling the pull rope 11 suspended near the well wall, striking the bell disc 5 to produce a sound. The number of sounds is the same as the number of normal hoisting signal points. After hearing it, the wellhead signalman sends a signal to the machine room through a dot device, and normal hoisting operation is resumed. This is suitable for situations where the signal is interrupted, enabling mechanical operation to transmit signals, playing a safety hoisting protection role, and reducing the safety risks of hoisting operation.
[0021] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, a stop block 12 is fixedly connected to the middle of the slide rod 4, the bell disc 5 is located above the stop block 12, a top plate 13 is fixedly connected to the top of the slide rod 4, a collar 14 is connected to the end of the rotating rod 7 away from the bell hammer 8, the pull rope 11 passes through the collar 14, a connecting rod 15 is installed on the bracket 6, and a rotating hole 16 is opened on the rotating rod 7 to cooperate with the connecting rod 15. With the stop block 12 in place, the bell disc 5 is located above the stop block 12, so that in its natural state, there is space between the bell hammer 8 and the bell disc 5, allowing it to be struck to generate a sound signal. With the collar 14 in place, one end of the pull rope 11 passes through the collar 14 and hangs down onto the hanging plate, and then the pull rope 11 is fixed to the collar 14 for easy raising and lowering.
[0022] In this embodiment, as Figures 1-4 As shown, the working process of the mechanical signal device provided in this embodiment is as follows:
[0023] The number of normal hoisting signal points is agreed upon, and a mechanical signal device is installed near the wellhead signal room. In the event of a signal interruption, the personnel inside the well pull rope 11 to operate the bell hammer 8 and strike the bell disc 5 to make a sound, thus contacting the ground signalman. Once the wellhead signalman hears that the number of sounds is the same as the number of normal hoisting signal points, he sends a signal to the vehicle room through the marker device, and normal hoisting operation resumes.
[0024] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
