As an example, the safety barrier 20 may include five barrier units 100, with the five barrier units 100 being connected end-to-end in sequence to form a circular barrier. Each segment of the guardrail unit 100 is of an arc-shaped structure, and the arc lengths of each segment of the guardrail unit 100 may be equal or unequal.

In the embodiment of the present utility model, each segment of guardrail unit 100 is a minor arc, and the arc lengths are equal.

Of course, in other embodiments, the number of barrier units 100 may be two, three, four, six, or other numbers.

It should be noted that, the safety barrier 20 according to the embodiment of the present utility model is designed to include at least two segments of barrier units 100, on one hand, the weight of each barrier unit 100 can be reduced, and further the moment of inertia and shake can be reduced; on the other hand, the storage and transportation of the respective barrier units 100 are facilitated; in yet another aspect, the safety barrier 20 is easily removed so that airport personnel open the safety barrier 20 to gain access to the interior of the safety barrier 20.

For convenience of description, the five-stage guardrail unit 100 is defined as a first guardrail unit 101a, a second guardrail unit 101b, a third guardrail unit 101c, a fourth guardrail unit 101d, and a fifth guardrail unit 101e, respectively. As shown in the counterclockwise direction of fig. 3, the first barrier unit 101a is connected to the second barrier unit 101b, the second barrier unit 101b is connected to the third barrier unit 101c, the third barrier unit 101c is connected to the fourth barrier unit 101d, the fourth barrier unit 101d is connected to the fifth barrier unit 101e, and the fifth barrier unit 101e is connected to the first barrier unit 101 a.

With continued reference to fig. 1 and 2, each guardrail unit 100 includes a stationary section 110 for connection to the cross-member 11 and a movable section 120 movably connected to the stationary section 110.

As shown in fig. 3 and 4, in the at least two segments of guardrail unit 100, a connection 130 is formed between each two adjacent fixed segments 110, wherein at least one connection 130 is a detachable connection structure, and the connection 130 adjacent to the connection 130 is a rotatable connection structure. Adjacent two movable sections 120 are connected through a flexible member 140. Meanwhile, the flexible member 140 corresponding to the detachable connection structure is detachably disposed between the two movable sections 120.

In the embodiment of the present utility model, the connection 130 between the fixed segment 110 of the first guardrail unit 101a and the fixed segment 110 of the second guardrail unit 101b is a detachable connection structure, and the connection 130 between the fixed segment 110 of the second guardrail unit 101b and the fixed segment 110 of the third guardrail unit 101c, and the connection 130 between the fixed segment 110 of the fifth guardrail unit 101e and the fixed segment 110 of the first guardrail unit 101a are rotatable connection structures.

The fixed segment 110 of the third barrier unit 101c and the fixed segment 110 of the fourth barrier unit 101d and the fixed segment 110 of the fifth barrier unit 101e may be a rotatable connection structure and/or a fixed connection structure.

Two adjacent movable segments 120 are connected through a flexible member 140, so that each movable segment 120 can independently move. When one of the movable segments 120 moves relative to the corresponding fixed segment 110 of the movable segment 120, two movable segments 120 connected adjacent to the movable segment 120 are not affected.

In the embodiment of the present utility model, the flexible member 140 between the movable section 120 of the first barrier unit 101a and the movable section 120 of the second barrier unit 101b is detachably connected between the two movable sections 120.

It is understood that the pliable component 140 may be a chain, rope, or other pliable component.

As shown in fig. 4, since the connection 130 between the fixed section 110 of the first barrier unit 101a and the fixed section 110 of the second barrier unit 101b is a detachable connection structure, and the connection 130 between the fixed section 110 of the fifth barrier unit 101e and the fixed section 110 of the first barrier unit 101a and the connection 130 between the fixed section 110 of the second barrier unit 101b and the fixed section 110 of the third barrier unit 101c are all rotatable connection structures, the fixed section 110 of the first barrier unit 101a and the fixed section 110 of the second barrier unit 101b can be separated, the movable section 120 of the first barrier unit 101a and the movable section 120 of the second barrier unit 101b can be separated, and airport personnel can enter the safety barrier 20 through the opening between the first barrier unit 101a and the second barrier unit 101b to perform maintenance, emergency bridge withdrawal, and the like.

As shown in fig. 5, as an example, the manner of fixing connection between the fixing section 110 of the third barrier unit 101c and the fixing section 110 of the fourth barrier unit 101d and between the fixing section 110 of the fourth barrier unit 101d and the fixing section 110 of the fifth barrier unit 101e may be: a fixing member 150 is provided, and the fixing member 150 is fixedly connected to the fixing section 110 of the third guardrail unit 101c and the fixing section 110 of the fourth guardrail unit 101d, or the fixing member 150 is fixedly connected to the fixing section 110 of the fourth guardrail unit 101d and the fixing section 110 of the fifth guardrail unit 101e. In the embodiment of the present utility model, the third guardrail unit 101c, the fourth guardrail unit 101d and the fifth guardrail unit 101e are fixed to each other to form a relatively fixed portion, the first guardrail unit 101a and the fifth guardrail unit 101e and the second guardrail unit 101b and the third guardrail unit 101c are rotatably connected, the first guardrail unit 101a and the second guardrail unit 101b are detachably connected, and after the whole assembly connection, the whole is formed with relatively fixed position and substantially unchanged shape when no external force is applied.

The safety barrier 20 further includes a universal wheel 160, and the universal wheel 160 is rotatably connected to the fixed section 110 of the barrier unit 100 for contacting the ground to support the safety barrier 20 to move with the movement of the traveling mechanism body 10.

As shown in fig. 6, a locking member 170 is further provided between the fixed section 110 of the second barrier unit 101b and the fixed section 110 of the third barrier unit 101c, and the locking member 170 is used to lock the two fixed sections 110 when the safety barrier 20 is in the open state. Meanwhile, a locking member 170 is also provided between the fixed section 110 of the first barrier unit 101a and the fixed section 110 of the fifth barrier unit 101e.

As shown in fig. 7 and 8, the detachable connection structure between the fixed section 110 of the first barrier unit 101a and the fixed section 110 of the second barrier unit 101b may employ a mortise lock structure 180.

Specifically, one of the two fixed segments 110 is provided with a mortise lock structure 180 and the other is provided with a jack. The mortise lock structure 180 includes a base 183, a button 181, and a latch tongue 182, the latch tongue 182 being telescopically coupled to the base 183, the button 181 being movably coupled to the base 183 and being in linkage with the latch tongue 182. After pressing button 181, latch tongue 182 is retracted relative to base 183. When the button 181 is not stressed, the latch tongue 182 extends out of the base 183.

When the safety rail 20 is in the closed condition, the latch 182 extends into the receptacle. When it is desired to open the first barrier unit 101a and the second barrier unit 101b, the button 181 is pressed and the latch tongue 182 is retracted to withdraw from the receptacle.

Of course, in other embodiments, the removable connection structure is not limited to the mortise lock structure 180, and for example, a bolt connection, a latch connection, etc. may be used, which are not illustrated herein.

With continued reference to fig. 7, a second detecting element 190 is further disposed between the first guardrail unit 101a and the second guardrail unit 101b, and the second detecting element 190 is configured to detect an open/close state of the first guardrail unit 101a and the second guardrail unit 101b, so as to improve safety.

In the embodiment of the present utility model, the second detecting element 190 is mounted on one of the fixed segment 110 of the first guardrail unit 101a and the fixed segment 110 of the second guardrail unit 101b, and the other fixed segment 110 is provided with a trigger member. When the first guard rail unit 101a and the second guard rail unit 101b are closed, the trigger triggers the second detection element 190.

As shown in fig. 1, 9 and 10, the safety barrier 20 is connected to the cross beam 11 by a connection assembly 200. It can be appreciated that since the safety barrier 20 is connected to the cross beam 11 of the traveling mechanism body 10 regardless of the movement of the traveling wheel frame 12, when the traveling wheel frame 12 rotates relative to the cross beam 11, the safety barrier 20 does not rotate with the rotation of the traveling wheel frame 12, avoiding the problem of drag caused by the rotation of the safety barrier 20, and improving safety.

In the embodiment of the present utility model, the two ends of the beam 11 in the length direction are both provided with the connection assemblies 200, the fixed section 110 of the fifth guardrail unit 101e is connected to the beam 11 through one of the connection assemblies 200, and the fixed section 110 of the third guardrail unit 101c is connected to the beam 11 through the other connection assembly 200.

The connection assembly 200 includes a first connection member 210, a second connection member 220, and an insert 230, the first connection member 210 is connected with the cross beam 11, the second connection member 220 is connected with the safety barrier 20, the first connection member 210 is provided with an insertion portion 211, and the insert 230 is connected to the second connection member 220 and inserted into the insertion portion 211.

In the embodiment of the present utility model, the two ends of the beam 11 in the length direction are respectively provided with a first connecting piece 210, and the fixed section 110 of the fifth guardrail unit 101e and the fixed section 110 of the third guardrail unit 101c are respectively fixedly provided with a second connecting piece 220. The first connector 210 may be rod-shaped and disposed perpendicular to the ground. The second connecting member 220 may also have a rod shape and be disposed parallel to the ground. The first connector 210 and the second connector 220 may be vertically disposed.

As an example, the plug portion 211 includes a groove, an extending direction of the groove is perpendicular to the ground, at least a portion of the insert 230 is movably received in the groove, and the insert 230 can move along the extending direction of the groove. Since the insert 230 is movably received in the recess in a direction perpendicular to the ground, the safety rail 20 is movable in a direction perpendicular to the ground with respect to the running gear body 10. Thus, when the travelling wheel 13 walks on uneven ground, the safety barrier 20 can move back and forth relative to the travelling mechanism body 10 according to the road surface condition, so that the safety barrier 20 can be ensured to be always in contact with the ground, and the safety is improved.

When the travelling mechanism body 10 moves along the front-rear direction, the groove wall of the groove abuts against the insert 230, so that the travelling mechanism body 10 can drive the safety barrier 20 to move along the front-rear direction together.

With continued reference to fig. 9 and 10, along the axial direction of the second connector 220, the insert 230 may move relative to the second connector 220 to enable the insert 230 to be inserted into or removed from the socket portion 211. The connection assembly 200 further includes a locking member 240, the locking member 240 being coupled to the second connection member 220 and/or the insert 230 for locking the insert 230 in a predetermined position on the second connection member 220. By adjusting the positions of the inserts 230 at both ends of the cross beam 11 in the length direction on the second link 220, the center of the safety barrier 20 can be substantially coincident with the rotation center of the traveling wheel frame 12.

As an example, the locking member 240 is screwed onto the second connecting member 220 and abuts against the insert 230. The locking member 240 may be a locking nut, but is not limited thereto.

The insert 230 includes an insertion portion 231 and a flange 232, at least a portion of the insertion portion 231 is inserted into the insertion portion 211, and the flange 232 is protruded from an outer periphery of the insertion portion 231. Preferably, a gap is formed between the flange 232 and the first connector 210 during installation, and since the flange 232 is not in direct contact with the first connector 210, but a gap is formed between the flange 232 and the first connector 210, when the running gear body 10 walks on a road condition with uneven ground or the boarding bridge is inclined, the first connector 210 is not directly abutted with the flange 232, so that on one hand, the safety barrier 20 is ensured to be always in contact with the ground, and on the other hand, the insert 230 is prevented from being damaged due to the extrusion of the first connector 210.

The process of installing the safety barrier 20 on the running gear body 10 will be described in detail with reference to fig. 4 and 11 to 16. As shown in fig. 4, the first barrier unit 101a and the second barrier unit 101b are separated, and at this time, the safety barrier 20 is in an open state and encloses the traveling mechanism body 10. Thereafter, as shown in fig. 11, the first barrier unit 101a and the second barrier unit 101b are connected.

The insert 230 and the locking member 240 provided on the fifth barrier unit 101e are moved to the outermost end of the second connector 220 facing away from the fifth barrier unit 101e, and then the insert 230 is inserted into the insertion portion 211 of the first connector 210 located at the left side of the cross member 11. At this time, the entire safety barrier 20 moves in the direction of the third barrier unit 101c, and thus the center of the safety barrier 20 is biased toward the third barrier unit 101c without overlapping the rotation center of the traveling wheel frame 12. Thereafter, the insert 230 provided on the third barrier unit 101c is inserted into the insertion portion 211 of the first connector 210 located on the right side of the cross member 11, and thereafter, the positions of the inserts 230 on the fifth barrier unit 101e and the third barrier unit 101c are adjusted along the length direction of the cross member 11 until the center of the safety barrier 20 substantially coincides with the rotation center of the traveling wheel frame 12.

It should be noted that, the above installation process is installed according to the order from left to right, if the installation is installed according to the order from right to left, the reverse operation is only needed, and the details are not repeated here. In addition, the disassembly process of the safety barrier 20 is performed in the reverse direction according to the above-described installation steps, and will not be described again here.

As shown in fig. 17 and 18, the boarding bridge travel mechanism touch stop function is realized by the movable section 120. Specifically, the movable segment 120 is coupled to the stationary segment 110 by a swing assembly 300. The swing assembly 300 includes a first swing link 310, a second swing link 320, and an elastic member 330, wherein one end of the first swing link 310 is hinged with the fixed section 110, the other end is hinged with the movable section 120, one end of the second swing link 320 is hinged with the fixed section 110, and the other end is hinged with the movable section 120. One end of the elastic member 330 is connected to the fixed segment 110, and the other end is connected to the first swing link 310 and/or the second swing link 320, so as to provide an elastic force to the movable segment 120 through the first swing link 310 and/or the second swing link 320, so that the movable segment 120 has a tendency to move towards the outside of the ring structure.

The boarding bridge traveling mechanism further includes a first detecting element 410, where the first detecting element 410 is disposed on the fixed segment 110, and is configured to detect a motion signal of the first swing link 310 or the second swing link 320, and generate a stop signal.

When the movable section 120 does not touch an obstacle, the movable section 120 is located at the outermost side of the safety barrier 20 due to the elastic force of the elastic member 330 applied to the first swing link 310 and the second swing link 320. When the movable segment 120 hits an obstacle, the movable segment 120 swings inward with respect to the fixed segment 110. When the first swing link 310 or the second swing link 320 swings a distance, the first detecting element 410 is triggered, the first detecting element 410 generates a stop signal, and the running mechanism body 10 stops moving at this time.

In the embodiment of the utility model, the other end of the elastic member 330 is connected to the first swing rod 310. Of course, in other embodiments, the other end of the elastic member 330 may be connected to the second swing link 320, or both the first swing link 310 and the second swing link 320.

As an example, the elastic member 330 may be a tension spring, but is not limited thereto.

In an embodiment, the first swing link 310 and the second swing link 320 are parallel to each other and have equal lengths, so that the movable section 120 can swing in a horizontal state all the time without turning over during the swing process of the movable section 120 touching an obstacle.

With continued reference to fig. 18, the boarding bridge walking mechanism further includes a limiting assembly 420, and the limiting assembly 420 includes a first limiting member 421 and a second limiting member 422. The first limiting member 421 is connected to the fixed segment 110, and is used for stopping the swing assembly 300 when the movable segment 120 moves to an outer maximum extent relative to the fixed segment 110. The second limiting member 422 is connected to the fixed segment 110 for stopping the swing assembly 300 when the movable segment 120 moves to an inner minimum amplitude with respect to the fixed segment 110.

In the embodiment of the present utility model, when the movable section 120 does not touch an obstacle, the first limiting member 421 abuts against the first swing rod 310 of the swing assembly 300 to stop the swing assembly 300 from further swinging outwards, so that the movable section 120 can only move to the position of the maximum amplitude outwards relative to the fixed section 110. During the process that the movable segment 120 touches an obstacle and moves inwards relative to the fixed segment 110, if the first detection element 410 can work normally, the movable segment 120 triggers the first detection element 410, the first detection element 410 generates a stop signal, and the boarding bridge stops moving; if the movable section 120 is forced to swing inwards, the movable section is abutted against the second limiting piece 422.

The first stopper 421 includes a first mounting member 421b, a first adjusting member 421c, and a magnetic attraction portion 421a. The first mounting member 421b is connected to the fixed segment 110, and the first adjusting member 421c is movably connected to the first mounting member 421b on the swing path of the swing assembly 300, and the magnetic attraction portion 421a is connected to an end of the first adjusting member 421c facing the swing assembly 300 for magnetically attracting the swing assembly 300.

In the swing path of the swing assembly 300, since the first adjusting member 421c is movably coupled to the first mounting member 421b, the maximum amplitude of the outward swing of the movable segment 120 with respect to the fixed segment 110 is also adjustable. Furthermore, since the magnetic attraction portion 421a can magnetically attract the swing assembly 300, when the movable section 120 is at the position of the outer maximum amplitude, the first swing link 310 of the swing assembly 300 is attracted by the magnetic attraction portion 421a, so as to reduce the swing of the movable section 120 during the boarding bridge traveling process.

As an example, the first adjusting member 421c is screwed to the first mounting member 421b, but not limited thereto.

The second limiting member 422 may include a second mounting member 422b and a second adjusting member 422c, and the connection relationship and the function of the second mounting member 422b and the second adjusting member 422c are similar to those of the first limiting member 421, and will not be described herein.
