[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] Embodiment 1:

[0039] See also Figures 1 to 4 A road-fall protection device includes a buffer component 1, a hinge component 2, an H-shaped plate 3, a suspended rail trolley 4, a side baffle 5 and a power-off control component 6.

[0042] The inflation unit 14 includes a cylindrical cavity 141, a cylindrical cavity 141 is opened inside the stop iron 137, a piston rod 142 is slidably installed inside the cylindrical cavity 141 through a compression spring 144, a traction rope 143 is fixedly connected to the upper end of the piston rod 142, and the upper end of the traction rope 143 is fixedly connected to the hinge assembly 2, an airbag 145 is arranged on the side wall of the stop iron 137 away from the cross bar 136, and an airway 1371 for connecting the airbag 145 and the cylindrical cavity 141 is opened in the middle of the side wall of the stop iron 137 away from the cross bar 136.

[0043] The hinge assembly 2 includes a hinge ball 21, and a mounting hole is provided at the end of the slide tube 12 away from the slide rod 11, and the hinge ball 21 is rotatably arranged in the mounting hole, and a hinge pin 22 is penetrated through the middle of the hinge ball 21, and the upper and lower ends of the hinge pin 22 are fixedly connected with connecting plates 23, and the connecting plate 23 is fixedly connected to the side wall of the H-shaped plate 3. The upper end surface of the connecting plate 23 located on the upper side is symmetrically provided with a reinforcing rib plate 24, and the reinforcing rib plate 24 and the side wall of the H-shaped plate 3 are fixedly connected. The connecting plate 23 located on the upper side is fixedly connected with a support plate 231 on the side away from the reinforcing rib plate 24, and the upper end of the traction rope 143 is fixedly bolted to the lower end surface of the support plate 231.

[0044] In this embodiment, the travel switch 64 can control the power on and off of the rail crane, thereby controlling the operating state of the rail crane.

[0045] When the track is in operation, the upper end of the rail crane is installed on the track, and the side part is installed on the end of the slide bar 11. The rail trolley 4 is hung on the track. During normal operation, the rail crane will drive the anti-drop protection device to move along the track. When the rail trolley 4 encounters a fork block, the rail trolley 4 will stop. At this time, the inertia of the rail crane will drive the slide bar 11 to slide into the slide cylinder 12. At the same time, the first stop ring 131 will drive the buffer spring 133 to compress, and the wire rope 135 is in a relaxed state. The reaction force of the spiral spring 138 will drive the cross bar 136 and the stop iron 137 to move in the direction of the travel switch 64, so that the wire rope 135 tends to be taut, and the travel switch 64 is triggered by the stop iron 137 to cut off the power of the rail crane. Under the action of the buffer spring 133, the rail crane gradually stops moving, thereby avoiding damage to it.

[0046] When the stop iron 137 moves toward the travel switch 64, the stop iron 137 will pull the traction rope 143. Since the connecting plate 23 is in a stationary state, the traction force of the stop iron 137 will cause the piston rod 142 to move upward in the cylindrical cavity 141. At this time, the air in the cylindrical cavity 141 will be compressed and enter the airbag 145 through the airway 1371, causing the airbag 145 to expand rapidly and contact the contact of the travel switch 64, thereby shortening the triggering time of the travel switch 64, which is beneficial to the rapid power off of the rail crane, reducing the braking time of the rail crane after encountering an obstruction in the fork, and improving its safety during use. At the same time, the flexible airbag 145 can play a certain protective role on the contact of the travel switch 64, thereby avoiding damage to the contact of the travel switch 64 due to excessive impact force.

[0047] Embodiment 2:

[0048] The technical solution is basically the same as that of the first embodiment, see Figure 1 , Figure 2 as well as Figures 5 to 7The difference is that: the side baffles 5 are symmetrically installed on the side walls of the H-shaped plate 3 and below the suspended rail trolley 4, and a power-off control component 6 is arranged inside the side baffles 5, and the power-off control component 6 is fixedly connected to the end of the buffer component 1.

[0049] The power-off control component 6 includes a fixed plate 61, to which the end of the buffer component 1 is fixedly connected, and a rectangular frame 62 is fixedly connected at the end of the fixed plate 61 away from the buffer component 1, and the lower end of the rectangular frame 62 is open, and a sliding plate 63 is slidably installed inside the rectangular frame 62, and a travel switch 64 is fixedly connected to the lower end of the sliding plate 63, and the travel switch 64 and the inner side wall of the lower end of the H-shaped plate 3 are slidably matched, and a driving unit 65 is arranged on the side wall of the rectangular frame 62, and the upper end of the driving unit 65 is fixedly connected to the lower end surface of the suspended rail trolley 4, and a lubrication unit 66 is arranged inside the rectangular frame 62, and the end of the lubrication unit 66 extends to the top of the hinge component 2.

[0050] The driving unit 65 includes a driving rod 651, and the driving rod 651 is fixedly connected to the lower end surface of the suspended rail trolley 4. The lower end of the driving rod 651 is fixedly connected to a No. 1 extrusion block 652. A No. 2 extrusion block 653 is arranged below the No. 1 extrusion block 652. The No. 2 extrusion block 653 is fixedly connected to the sliding shaft 654 can. The sliding shaft 654 slides through the side wall of the rectangular frame 62 and the end of the sliding shaft 654 away from the No. 2 extrusion block 653 is fixedly connected to the sliding plate 63. A return spring 655 is sleeved on the sliding shaft 654 between the rectangular frame 62 and the No. 2 extrusion block 653.

[0051] The lubrication unit 66 includes a transition oil barrel 661, and the transition oil barrel 661 is fixedly installed on the side wall of the rectangular frame 62 away from the sliding plate 63. A piston plate 663 is slidably installed inside the transition oil barrel 661 through a supporting spring 662. A ball head rod 664 is fixedly installed on the side wall of the piston plate 663, and the ball head end of the ball head rod 664 is abutted against the sliding plate 63. A supplementary oil barrel 665 is fixedly set on the upper end of the rectangular frame 62, and the oil outlet of the supplementary oil barrel 665 is connected to the inside of the transition oil barrel 661 through a one-way valve. The oil outlet of the transition oil barrel 661 is connected to a one-way oil injection pipe 666, and the end of the one-way oil injection pipe 666 extends to above the hinged ball 21.

[0052] During specific operation, when the rail trolley 4 moves to the end of the track and the staff fails to connect the track in time, the rail trolley 4 will be off the track. At this time, the rail trolley 4 will drive the H-shaped plate 3 and the side baffle plate 5 to rotate downward around the hinge point of the hinge ball 21 and the hinge pin 22 and fall down, and the rail trolley 4 will drive the driving rod 651 and the first extrusion block 652 to squeeze the second extrusion block 653 downward, so that the second extrusion block 653 drives the sliding shaft 654 to move toward the rail crane. At the same time, the reset spring 655 is compressed, and the sliding shaft 654 drives the sliding plate 63 and the travel switch 64 to move toward the direction close to the stop iron 137, thereby triggering the travel switch 64 to cut off the power of the rail crane to avoid its derailment and damage and cause an accident;

[0053] The H-shaped plate 3 will drive the support plate 231 to rotate synchronously during the process of rotating and falling downward. At this time, the end of the support plate 231 close to the rail crane will tilt up and apply a certain pulling force to the traction rope 143, which will cause the traction rope 143 to drive the piston rod 142 to move upward in the cylindrical cavity 141. At this time, the air in the cylindrical cavity 141 will be compressed and enter the airbag 145 through the air channel 1371, causing the airbag 145 to expand rapidly and quickly contact the contact of the travel switch 64, further shortening the triggering time of the travel switch 64, which is conducive to the rapid power off of the rail crane and improves the safety of the rail crane during operation;

[0054] When the sliding plate 63 moves toward the direction of the rail crane, it will drive the ball head rod 664 to move into the transition oil barrel 661. At this time, under the action of the piston plate 663, the support spring 662 is compressed, and the lubricating oil inside the transition oil barrel 661 will be sprayed to the connection between the articulated ball 21, the articulated pin 22 and the slide cylinder 12 through the one-way oil spray pipe 666 and lubricate, thereby reducing the friction between the articulated ball 21 and the slide cylinder 12. When the suspended rail trolley 4 derails, it ensures that the suspended rail trolley 4 can rotate downward around its hinge point and fall smoothly, thereby shortening the triggering time of the travel switch 64, which is conducive to its rapid power-off processing of the rail crane and avoiding the problem of derailment and damage to the rail crane.

[0055] The working principle of the present invention when in use:

[0056] 1. The upper end of the rail crane is installed on the track, and the side is installed on the end of the slide bar 11. The rail trolley 4 is hung on the track. During normal operation, the rail crane will drive the anti-drop protection device to move along the track. When the rail trolley 4 encounters a fork block, the rail trolley 4 will stop. At this time, the inertia of the rail crane will drive the slide bar 11 to slide into the slide cylinder 12. At the same time, the first baffle ring 131 will drive the buffer spring 133 to compress, and the wire rope 135 is in a relaxed state. The reaction force of the spiral spring 138 will drive the cross bar 136 and the stop iron 137 to move toward the travel switch 64, so that the wire rope 135 tends to be taut, and the travel switch 64 is triggered by the stop iron 137 to cut off the power of the rail crane. Under the action of the buffer spring 133, the rail crane gradually stops moving, thereby avoiding damage to it.

[0057] Second: When the stop iron 137 moves toward the travel switch 64, the stop iron 137 will pull the traction rope 143. Since the connecting plate 23 is in a stationary state, the traction force of the stop iron 137 will cause the piston rod 142 to move upward in the cylindrical cavity 141. At this time, the air in the cylindrical cavity 141 will be compressed and enter the airbag 145 through the air channel 1371, causing the airbag 145 to expand rapidly and contact the contact of the travel switch 64, thereby shortening the triggering time of the travel switch 64, which is conducive to the rapid power off of the rail crane, reducing the braking time of the rail crane after encountering a fork obstruction, and improving its safety during use. At the same time, the flexible airbag 145 can play a certain protective role on the contact of the travel switch 64, thereby preventing the contact of the travel switch 64 from being damaged due to excessive impact force;

[0058] 3. When the rail trolley 4 moves to the end of the track and the staff fails to connect the track in time, the rail trolley 4 will be off the track. At this time, the rail trolley 4 will drive the H-shaped plate 3 and the side baffle plate 5 to rotate downward around the hinge point of the hinge ball 21 and the hinge pin 22 and fall down, and the rail trolley 4 will drive the driving rod 651 and the first extrusion block 652 to squeeze the second extrusion block 653 downward, so that the second extrusion block 653 drives the sliding shaft 654 to move toward the rail crane. At the same time, the reset spring 655 is compressed, and the sliding shaft 654 drives the sliding plate 63 and the travel switch 64 to move toward the direction close to the stop iron 137, thereby triggering the travel switch 64 to cut off the power of the rail crane to avoid its derailment and damage and cause an accident;

[0059] Fourth: When the H-shaped plate 3 rotates downward and falls, it will drive the support plate 231 to rotate synchronously. At this time, the end of the support plate 231 close to the rail crane will tilt up and apply a certain pulling force to the traction rope 143. The pulling force will cause the traction rope 143 to drive the piston rod 142 to move upward in the cylindrical cavity 141. At this time, the air in the cylindrical cavity 141 will be compressed and enter the airbag 145 through the airway 1371, and the airbag 145 will expand rapidly and quickly contact the contact of the travel switch 64, further shortening the triggering time of the travel switch 64, which is conducive to the rapid power off of the rail crane and improves the safety of the rail crane during operation;

[0060] 5. When the sliding plate 63 moves toward the direction of the rail crane, it will drive the ball head rod 664 to move into the transition oil barrel 661. At this time, under the action of the piston plate 663, the support spring 662 is compressed, and the lubricating oil inside the transition oil barrel 661 will be sprayed to the connection between the articulated ball 21, the articulated pin 22 and the slide cylinder 12 through the one-way oil spray pipe 666 to lubricate, thereby reducing the friction between the articulated ball 21 and the slide cylinder 12. When the suspended rail trolley 4 derails, it ensures that the suspended rail trolley 4 can rotate downward around its hinge point and fall smoothly, thereby shortening the triggering time of the travel switch 64, which is conducive to its rapid power-off processing of the rail crane and avoiding the problem of derailment and damage to the rail crane.
