Description

Technical Field

[0001] The utility model relates to the field of monorail cranes, and more specifically to an anti-collision alarm device for a monorail crane locomotive. Background Art

[0002] Monorail crane is a system that uses a special I-beam hanging above the roadway as a track, and is connected by a group of hanging vehicles with various functions, and is towed by traction equipment to run along the track. Monorail crane is widely used in material handling, lifting, loading and unloading, and has become an indispensable and important equipment in modern industrial production.

[0003] After the existing monorail crane locomotive stops running, it is usually blocked by a car blocker when approaching the end of the track. The car blocker is a rigid blocking device. Although it plays a limiting role, it has the disadvantage of collision and spraining the track. When approaching the end of the track, if the driver does not slow down in time, he will directly hit the car blocker at a high speed. The high-speed collision will not only damage the car blocker itself, but more importantly, it will generate a huge impact force, causing direct physical damage to the track. Under the long-term cumulative effect, the track may have problems such as deformation and cracks, affecting the stability and safety of the entire transportation system. Utility Model Content

[0004] The utility model aims to overcome the defects of the prior art and provides a monorail crane anti-collision alarm device.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a monorail crane locomotive anti-collision alarm device comprises a slide rail, a car blocker is installed at the end of the slide rail, the car blocker comprises a U-shaped plate, the U-shaped plate is made of metal, and a rubber buffer pad is provided at the U-shaped plate, two sliding frames that can slide on the slide rail are installed at the slide rail, a cab is installed through the two sliding frames, a plurality of sensor blocks are installed at the bottom of the slide rail, the sensor blocks are detachably installed between the cab and the car blocker, a mounting hole is provided at the top of the cab, an electrical installation box is installed at the mounting hole, the top and bottom of the electrical installation box both have openings, the electrical installation box comprises an outer frame and a bottom cover detachably installed at the bottom of the outer frame, a controller and a rangefinder are installed in the electrical installation box, a speaker is installed at the controller, the outer frame has a sound-transmitting hole, an infrared sensor is installed at the rangefinder, and the rangefinder is used to detect the distance between the infrared sensor and the bottom of the slide rail.

[0006] Furthermore, a fixing screw is installed at the U-shaped plate, and a locking nut is provided at the fixing screw to fix the U-shaped plate and the slide rail.

[0007] Thereby, the car arrester is stably connected to the slide rail.

[0008] Furthermore, a substrate is installed on the bottom cover, and the controller and the rangefinder are both installed on the substrate. The bottom cover has a plurality of first nut columns, a plurality of second nut columns, and a plurality of third nut columns. The substrate has a plurality of first through holes that cooperate with the first nut columns, a plurality of second through holes that cooperate with the second nut columns, and a plurality of third through holes that cooperate with the third nut columns. The first nut column has a first threaded hole, the second nut column has a second threaded hole, and the third nut column has a third threaded hole.

[0009] Therefore, the controller, the distance meter and the base plate are installed by the locking bolts and the corresponding nut columns.

[0010] Furthermore, the controller and the rangefinder are both fixed with protrusions, and the protrusions have mounting holes.

[0011] This makes it easier to pass the locking bolt.

[0012] Furthermore, the bottom cover is fixedly connected to the outer frame by a first fixing bolt, the bottom cover has a fourth through hole matched with the first fixing bolt, and the bottom of the outer frame has a fourth threaded hole matched with the first fixing bolt.

[0013] The bottom cover is thus easy to remove, thereby facilitating maintenance.

[0014] Furthermore, the sensing block is fixedly connected to the slide rail via a second fixing bolt, the sensing block has a blind hole matched with the second fixing bolt, and the bottom of the slide rail has a fifth threaded hole matched with the second fixing bolt.

[0015] The induction block is thus easy to install and disassemble.

[0016] Furthermore, the sliding frame includes two side frames and a connecting block connecting the two side frames, the side frames are equipped with a first pulley and multiple second pulleys, the first pulley abuts against the slide rail, the second pulley abuts against the edge of the slide rail, and a mounting shaft is also installed between the two side frames. The top of the cab has a lifting ear, and the lifting ear has a through hole that cooperates with the mounting shaft.

[0017] Thus, the sliding frame is clamped on the slide rail through the installation shaft, and the plurality of second pulleys make the sliding frame move more smoothly, and the lifting lugs are used to hang the cab under the two sliding frames.

[0018] Furthermore, there are two sensing blocks, namely a first sensing block and a second sensing block. The distance between the first sensing block and the vehicle blocker is greater than or equal to 5 meters, and the distance between the second sensing block and the vehicle blocker is greater than or equal to 2.5 meters.

[0019] Therefore, when the locomotive reaches the first induction block, the controller controls the horn to sound an alarm to remind the driver to decelerate until the locomotive stops. When the locomotive passes the second induction block without decelerating, the locomotive is controlled to power off and stop.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] 1. The locomotive anti-collision alarm device of the present application detects that the locomotive is approaching the end of the slide rail through the cooperation of the rangefinder and the induction block. The controller controls the horn to alarm, thereby reminding the driver to slow down in time to avoid the locomotive directly colliding with the blocker, thereby improving the safety of locomotive operation.

[0022] 2. The locomotive anti-collision alarm device of the present application is provided with two sensing blocks. When improper operation or other circumstances cause the locomotive to fail to decelerate in time and pass the second sensing block, the PLC control box controls the locomotive to power off and shut down, thereby realizing double detection of the locomotive's driving status and further improving safety.

[0034] Working principle: The locomotive anti-collision alarm device of the present application has a power unit at the slide rail, and the power unit has a PLC control box. The power unit is controlled by the PLC control box program to propel the locomotive to move, and the PLC control box is connected to the controller in the electrical installation box (preferably, wireless connection is adopted). During specific detection, when the locomotive is running on the slide rail, the rangefinder will continue to measure the distance between the rangefinder and the bottom of the slide rail. When the rangefinder moves below the sensing block, the distance detected by the rangefinder becomes shorter, thereby sending a signal to the controller, and the controller executes the corresponding command. Based on the speed as the basis for judgment, when the locomotive travels to the first sensing block, the controller controls the horn to alarm and remind the driver to slow down. When the locomotive travels to the second sensing block, since the PLC control box has controlled the power unit to slow down the locomotive, the controller controls the horn not to alarm. When the locomotive passes the first sensing block, if the driver does not slow down or the locomotive does not slow down due to improper operation, the PLC control box will control the locomotive to shut down when the locomotive passes the second sensing block to prevent the locomotive from colliding with the car blocker at the end. At this time, due to inertia, the locomotive will continue to travel for a distance, and the rubber buffer pad can play a certain buffering role.
