Abstract
Description
Technical Field
[0001] This utility model relates to a vehicle buffer limit, specifically an infrared limit buffer device for a vehicle end beam. Background Technology
[0002] When the gantry crane stops at the side, it often hits the side rail stop, making a loud impact noise and sometimes even damaging the crane. Currently, the crane's limit buffer uses only a buffer rod in conjunction with a spring, but the crane motor is manually controlled, so the limit buffer effect is not good and the impact noise still occurs. Utility Model Content
[0003] To address the shortcomings of the existing technology, this utility model provides an infrared limiting and buffering device for a crane end beam. This utility model uses infrared light to control the crane motor to stop and uses a buffer component to buffer the impact, prevent collisions, and protect the driving safety.
[0004] To achieve the above technical objectives, this utility model adopts the following technical solution: an infrared limiting and buffering device for a traveling beam, comprising a buffer assembly disposed on the traveling beam and a limiting plate disposed at the end of the traveling track. The limiting plate is provided with an infrared emitting end and an infrared receiving end at the end near the buffer assembly. When the traveling beam moves between the infrared emitting end and the infrared receiving end, the infrared receiving end cannot receive infrared light, and the traveling beam begins to decelerate. The limiting plate is also provided with a limiting positioning groove, and the buffer assembly can be positioned in the limiting positioning groove.
[0005] The buffer assembly includes a housing with a shaft hole, a spring and a moving rod inside. One end of the moving rod is located inside the housing and connected to the spring, while the other end extends outside the housing and is provided with a collision plate. A blocking block is provided at the end of the housing. The housing is fixed to the end beam of the traveling vehicle. The collision plate can block the infrared rays emitted by the infrared emitting end and can also be positioned in the limiting positioning groove.
[0006] The movable rod is also provided with a limiting ring, and the shaft hole of the housing is also provided with a limiting groove. The limiting ring is placed in the limiting groove. The limiting ring is provided with a protrusion. The diameter of the limiting ring is larger than the diameter of the movable rod. The diameter of the movable rod is larger than the diameter of the protrusion. The protrusion extends into the spring.
[0007] The outer shell is also threadedly connected to a force-bearing shell, which is provided with a force-bearing ring that can contact the impact plate.
[0008] The impact plate is provided with a first buffer pad, and the force-bearing ring is provided with a second buffer pad.
[0009] The limiting plate includes a support plate, a connecting plate, and two mounting columns. The lower end of the support plate is fixed to the trolley track, the connecting plate is fixed to the top of the support plate, and the two mounting columns are fixed to the ends of the connecting plate. The infrared transmitter and the infrared receiver are respectively mounted on the two mounting columns.
[0010] The support plate is fixed with a limiting positioning plate, and the limiting positioning plate has the limiting positioning groove.
[0011] In summary, this utility model achieves the following technical effects:
[0012] When the crane end beam moves to the infrared position, the infrared light is blocked and the receiver cannot receive it. At this time, the infrared receiver can send a signal to the crane motor, which reduces its speed and then stops. The crane end beam then decelerates and stops. The buffer component can buffer the crane end beam when the motor stops working but the crane end beam still has inertia and moves forward, preventing the crane end beam from being damaged and also preventing a large impact sound.

[0023] Example:
[0024] Figure 1 It is an infrared limiting and buffering device for the end beam of a crane. Figure 2 yes Figure 1The side view includes two train tracks 1 and a train end beam 2, including a buffer assembly 3 disposed on the train end beam 2, and a limiting plate 4 disposed at the end of the train track 1. The limiting plate 4 is provided with an infrared emitting end 5 and an infrared receiving end 6 at the end near the buffer assembly 3. When the train end beam 2 moves between the infrared emitting end 5 and the infrared receiving end 6, the infrared receiving end 6 does not receive infrared light, and the train end beam 2 begins to decelerate. The limiting plate 4 is also provided with a limiting positioning groove 47, in which the buffer assembly 3 can be positioned.
[0025] When the crane end beam 2 moves to the infrared position, the infrared light is blocked and the receiver cannot receive the infrared light. At this time, the infrared receiver can send a signal to the crane motor (not shown). The crane motor reduces its speed and then stops. The crane end beam 2 starts to decelerate and then stops. The buffer component 3 can buffer the crane end beam when the motor stops working but the crane end beam still has inertia and moves forward, preventing the crane end beam from being damaged and also preventing a large impact sound.
[0026] Figure 3 This is a schematic diagram of a buffer assembly. The buffer assembly 3 includes a housing 31 with a shaft hole. A spring 33 and a moving rod 34 are installed inside the housing 31. One end of the moving rod 34 is located inside the housing 31 and connected to the spring 33, while the other end extends outside the housing 31 and is provided with a collision plate 37. A blocking block 32 is provided at the end of the housing 31. The housing 31 is fixed to the end beam 2 of the traveling vehicle. The collision plate 37 can block the infrared rays emitted by the infrared emitting end 5 and can also be positioned in the limiting positioning groove 47.
[0027] The movable rod 34 is also provided with a limiting ring 35, and the shaft hole of the housing 31 is also provided with a limiting groove. The limiting ring 35 is placed in the limiting groove. The limiting ring 35 is provided with a protrusion 36. The diameter of the limiting ring 35 is larger than the diameter of the movable rod 34, and the diameter of the movable rod 34 is larger than the diameter of the protrusion 36. The protrusion 36 extends into the spring 33.
[0028] The outer shell 31 is also threadedly connected to a force-bearing shell 38, which is provided with a force-bearing ring 39, and the force-bearing ring 39 can contact the impact plate 37.
[0029] The impact plate 37 is provided with a first buffer pad 7, and the force ring 39 is provided with a second buffer pad 8.
[0030] This utility model features a housing 31, which is fixed to the top of the end beam 2 of the crane. This design minimizes the protruding length of the entire buffer assembly, allowing the end beam to stop as close to the side as possible. The moving rod 34 is equipped with a collision plate 37, which contacts the limiting positioning groove 47 of the limiting plate 4. The moving rod 34 is pressed into the housing 31, compressing the spring 33 and achieving a buffering effect, preventing loud impact noise and damage to the crane. When the end beam continues to move, the moving rod returns to its original position under the action of the spring 33, but it will not detach from the housing 31 under the action of the limiting ring 35 and the limiting groove. The force-bearing shell 38 can be adjusted to change the buffer stroke of the moving rod. Of course, if necessary, the force-bearing shell 38 can be fixed with a fastening nut.
[0031] This utility model is equipped with a buffer component 3, which can provide a buffering force to the end beam of the vehicle during inertial forward movement to prevent impact.
[0032] Figure 4 This is a schematic diagram of a limiting plate. The limiting plate 4 includes a support plate 42, a connecting plate 41, and two mounting posts 43. The lower end of the support plate 42 is fixed to the trolley track 1, the connecting plate 41 is fixed to the top end of the support plate 42, and the two mounting posts 43 are fixed to the ends of the connecting plate 41. The infrared emitting end 5 and the infrared receiving end 6 are respectively mounted on the two mounting posts 43.
[0033] The support plate 42 is fixed with a limiting positioning plate 46, and the limiting positioning plate 46 has a limiting positioning groove 47.
[0034] This utility model features a limiting plate that can accommodate an infrared receiver and transmitter, and can work with a buffer assembly to achieve buffering and positioning.
[0035] Working principle:
[0036] When the end beam 2 of the traveling vehicle carries the buffer assembly 3, the impact plate 37 of the buffer assembly 3 blocks the infrared receiver. The infrared receiver sends a signal, the traveling motor decelerates and stops working, and the end beam of the traveling vehicle continues to move forward under inertia. The impact plate 37 of the buffer assembly contacts the limiting positioning groove 47 and slowly stops under the action of the spring.
[0037] This utility model Figure 1 and Figure 2 Only one end of the track is shown with a limiting plate and a buffer assembly. In actual use, limiting plates can be installed at both ends of the track, and buffer assemblies can be installed at both ends of the trolley end beam.
[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
