Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] Combination Figures 1 to 9 As shown, this utility model proposes an anti-runaway device for monorail cranes operating in inclined shafts. This anti-runaway device can prevent monorail cranes from breaking their ropes or becoming detached, thereby ensuring the safety of coal mine workers and the safe operation of electromechanical equipment. The anti-runaway device mainly includes structural components such as an intercepting rope 21, a buffer mechanism 3, a cylinder 41, a traction rope 42, and a pulley 43.

[0018] Combination Figure 1 , Figure 2 and Figure 9As shown, the intercepting rope 21 is a key component used to directly stop a monorail crane that has broken its rope or become unhooked. It is horizontally positioned within the roadway to divide the roadway space. When a monorail crane experiences a rope breakage or becomes unhooked and slides uncontrollably, the intercepting rope 21 effectively prevents it from continuing to slide, avoiding more serious accidents and ensuring the safety of underground workers and electromechanical equipment. The intercepting rope 21 of this invention is made of steel wire rope, which has high strength, good toughness, and wear resistance, and can withstand significant impact forces, ensuring that it will not easily break when stopping the monorail crane and guaranteeing the reliability of the anti-runaway device.

[0019] Combination Figure 1 and Figure 2 As shown, the two ends of the intercepting rope 21 are connected to the roadway sidewall 12 through the buffer mechanism 3. The buffer mechanism 3 is set between the end of the intercepting rope 21 and the roadway sidewall 12. Its main function is to buffer and absorb the impact force when the intercepting rope 21 is subjected to the impact and pull of the monorail crane, thereby reducing the instantaneous impact force borne by the intercepting rope 21 and the entire anti-runaway device, preventing damage to the device due to excessive impact force, and extending the service life of the device.

[0020] Combination Figure 3 and Figure 4 As shown, the buffer mechanism 3 mainly includes structural components such as a base 31, a housing 32, a guide rod 33, a buffer spring 35, a sliding sleeve 34, a connecting plate 36, and a shackle 37. The rear side of the base 31 is fixedly connected to the roadway sidewall 12, providing stable support for the entire buffer mechanism 3. The housing 32 is cuboid in shape, and its rear side is fixedly connected to the front side of the base 31. An opening is provided in the center of the front plate 321 of the housing 32, a design that facilitates the connection of the intercepting rope 21 to the buffer mechanism 3.

[0021] Combination Figure 4 As shown, the interior of the outer shell 32 is provided with a plurality of parallel guide rods 33. In this embodiment, four guide rods 33 are provided, and the four guide rods 33 are symmetrically arranged at the corners of the connecting plate 36. This arrangement can make the connecting plate 36 bear the force evenly when it is subjected to tension, thus ensuring the stability and buffering effect of the buffer mechanism 3.

[0022] Combination Figure 4 As shown, one end of the guide rod 33 is fixedly connected to the base 31, and the other end of the guide rod 33 is fixedly connected to the front side plate 321 to ensure the overall stability of the buffer mechanism 3. A buffer spring 35 and a sliding sleeve 34 are slidably installed on each guide rod 33. One end of the buffer spring 35 is connected to the sliding sleeve 34, and the other end of the buffer spring 35 abuts against the front side plate 321 of the outer shell 32. When the intercepting rope 21 is impacted, the sliding sleeve 34 slides along the guide rod 33, compressing the buffer spring 35, which can convert the kinetic energy of the monorail crane into elastic potential energy and achieve a buffering effect.

[0023] Combination Figure 2 and Figure 4 As shown, multiple sliding sleeves 34 are connected by a connecting plate 36. A shackle 37 is provided at the center of the connecting plate 36. The end of the intercepting rope 21 is connected to the shackle 37 through the opening of the front side plate 321, so as to transmit the tension of the intercepting rope 21 to the buffer mechanism 3.

[0024] Specifically, such as Figure 5 As shown, when the intercepting rope 21 is not under tension, the buffer spring 35 is in a naturally extended state, and the sliding sleeve 34 and the connecting plate 36 are relatively far away from the front side plate 321; Figure 6 As shown, when a sports car accident occurs, the intercepting rope 21 is pulled by the out-of-control vehicle. This pulling force is transmitted to the connecting plate 36 through the shackle 37. The connecting plate 36 drives multiple sliding sleeves 34 to slide together along the guide rod 33 towards the front side plate 321, thereby strongly compressing the buffer spring 35. At this time, the huge kinetic energy of the vehicle is converted into the elastic potential energy of the buffer spring 35 in this process, realizing flexible braking and energy absorption.

[0025] Combination Figure 1 and Figure 9 As shown, cylinder 41 is mounted on the side wall 12 of the tunnel. Its telescopic end is connected to one end of the traction rope 42, and the other end of the traction rope 42 passes over pulley 43 and is connected to the intercepting rope 21. Cylinder 41 provides power to pull the intercepting rope 21 away from the tunnel floor 11 via the traction rope 42. Pulley 43 changes the direction of force on the traction rope 42, ensuring that the pulling force of cylinder 41 is effectively transmitted to the intercepting rope 21, thus guaranteeing the normal operation of the device.

[0026] It should be noted that during normal transport of the monorail crane, the intercepting rope 21 rests on the tunnel floor 11 under its own weight and does not affect the normal passage of the vehicle; when it is necessary to block the monorail crane, the cylinder 41 provides power and the traction rope 42 lifts the intercepting rope 21 to a certain height to block the monorail crane that has broken rope or become unhooked.

[0027] Combination Figure 1 As shown, in order to enhance the interception effect, multiple interception ropes 21 are provided. Both ends of each interception rope 21 are connected to the side wall 12 of the roadway through the buffer mechanism 3. Multiple interception ropes 21 can form multiple interception defense lines, further improving the reliability of the anti-runaway device.

[0028] In addition, combined Figure 1 and Figure 8As shown, multiple interception ropes 21 are connected by a limiting plate 22. The limiting plate 22 has through holes in the same number as the number of interception ropes 21. Each interception rope 21 passes through a through hole independently. The limiting plate 22 can ensure the relative position stability between the multiple interception ropes 21 and prevent the interception ropes 21 from getting tangled or misaligned when subjected to impact, thus affecting the interception effect.

[0029] Combination Figure 9 As shown, the tunnel sidewall 12 is also equipped with a speed measuring instrument 51 and an audible and visual alarm 52, and a controller. The control terminals of the speed measuring instrument 51, the audible and visual alarm 52, and the cylinder 41 are all connected to the controller via signal cables. The speed measuring instrument 51 can monitor the running speed of the monorail crane in real time and transmit this speed data to the controller. When the running speed of the monorail crane exceeds the preset safety threshold, the controller will immediately trigger the audible and visual alarm 52 to issue an alarm signal, reminding the underground workers to pay attention to safety. At the same time, the controller will also control the cylinder 41 to start, and quickly raise the intercepting rope 21 to a certain height through the traction rope 42 to form an interception line to prevent the monorail crane with broken rope or detached hook from continuing to slide down, thereby effectively avoiding accidents and ensuring the safety of coal mine workers and the safe operation of electromechanical equipment.

[0030] Combination Figures 1 to 9 As shown, this utility model proposes an anti-runaway vehicle device for monorail crane inclined roadway transportation. By setting multiple intercepting ropes 21 inside the roadway, it prevents the runaway vehicle from continuing to slide down, avoiding the expansion and deterioration of the accident, and ensuring the safety of underground workers and electromechanical equipment. Furthermore, by adding a buffer mechanism 3, this utility model can effectively convert the huge kinetic energy of the runaway vehicle into the elastic potential energy of the buffer spring 35, realizing flexible braking and energy absorption. This utility model, through the monitoring and early warning functions of the speed measuring instrument 51 and the audible and visual alarm 52, can promptly detect and deal with potential safety hazards, further improving the safety of coal mine transportation. Powered by the cylinder 41, the position of the intercepting ropes 21 can be adjusted in real time according to the operating status of the monorail crane. In practical applications, it has the characteristics of simple structure, convenient installation, and high reliability.

[0031] Of course, the above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model and should be protected by the present utility model.
