[0039] like Figure 1 and Figure 4 As shown, a cage vehicle operation safety auxiliary device includes a main frame and a display 2 arranged on the main frame.

[0040] like Figure 8 As shown, the main frame includes a base frame 11, and the four corners of the lower side of the base frame 11 are respectively provided with walking wheels 12. The front end of the base frame 11 is provided with a first vertical frame 13 extending upward perpendicularly to the base frame 11, and the upper end of the first vertical frame 13 is provided with a horizontal frame 14 extending forward perpendicularly to the first vertical frame 13. A camera 3 is provided on the horizontal frame 14, and the picture taken by the camera 3 can be displayed on the display 2 in real time. A rib plate 15 is provided between the horizontal frame 14 and the first vertical frame 13. A locking mechanism for connecting with the cage car 6 is provided on the first vertical frame 13 below the horizontal frame 14. When the cage car 6 is connected to the first vertical frame 13 through the locking mechanism, the camera 3 is located above the cage car 6, and the environment around the cage car 6 can be displayed on the display 2.

[0041] like Figure 1 , Figure 4 and Figure 8 As shown, the locking mechanism includes two cross bars 161 extending in the transverse direction, and the middle portion of the cross bar 161 is fixedly connected to the front side of the first upright frame 13. Exemplarily, the middle portion of the cross bar 161 is fixedly connected to the front side of the first upright frame 13 by welding. Claws 1621 are respectively provided at both ends of the cross bar 161, and the hooking portion of the claw 1621 faces the front side. The claw 1621 is hinged to the cross bar 161 through a hinge shaft 1622, and the axis of the hinge shaft 1622 extends in the vertical direction. An elastic member is provided between the claw 1621 and the cross bar 161 for preventing the front end portion of the claw 1621 from swinging outward. As a specific embodiment, as Figure 3As shown, the elastic member described in this embodiment is a torsion spring 1623 sleeved on the hinge shaft 1622. A connecting rod 163 is provided between the two claws 1621 located on the same side of the first stand 13, and the upper end of the connecting rod 163 is fixedly connected to the rear end of the claw 1621 located on the upper side in a detachable manner, and the lower end of the connecting rod 163 is fixedly connected to the rear end of the claw 1621 located on the lower side in a detachable manner.

[0042] like Figure 8 As shown, the left and right ends of the base frame 11 are respectively provided with second upright frames 17 extending upward perpendicular to the base frame 11, the lower end of the second upright frame 17 is fixedly connected to the base frame 11 by welding, and the front end of the second upright frame 17 is fixedly connected to the first upright frame 13 by welding.

[0043] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, a pull rod 164 extending in the transverse direction is provided between the two second frames 17, and the two ends of the pull rod 164 are respectively slidably connected with the second frames 17, and the pull rod 164 can slide forward and backward relative to the second frames 17. As a specific implementation, the second frames 17 described in this embodiment are provided with a guide slot 171 in an oblong hole structure, and the guide slot 171 passes through the second frames 17 in the transverse direction. The two ends of the pull rod 164 respectively pass through the guide slot 171 on the second frames 17 and extend to the outside of the second frames 17 (with the side opposite to the two second frames 17 as the inner side). The two ends of the pull rod 164 are located on the outside of the second frames 17 (with the side opposite to the two second frames 17 as the inner side) and are respectively provided with limit nuts 1641. The limit nuts 1641 play a stopper role, and are used to limit the freedom of the pull rod 164 to move in the axial direction. The second stand 17 is provided with a guide pulley 165 at the front side of the guide slot 171. The two connecting rods 163 are connected to the pull rod 164 through traction ropes 166, one end of the traction rope 166 is connected to the connecting rod 163, and the other end of the traction rope 166 is connected to the pull rod 164 after passing through the guide pulley 165.

[0044] When the pull rod 164 is pulled backward, the pull rod 164 pulls the connecting rods 163 on both sides to move toward the stand through the traction rope 166, and the two connecting rods 163 can simultaneously drive the four claws 1621, and make the front ends of the four claws 1621 swing outward, and the locking mechanism is in an open state. When the pull rod 164 is released, the four claws 1621 will reset under the elastic restoring force of the torsion spring 1623, that is, the front ends of the claws 1621 swing inward, and the swing of the claws 1621 will drive the two connecting rods 163 to move away from the stand, and the movement of the connecting rod 163 will drive the pull rod 164 to move forward through the traction rope 166, and the locking mechanism is in a locked state.

[0045] Furthermore, if Figure 4 and Figure 5 As shown, the front end of the horizontal frame 14 is provided with a mounting rod 18 extending in the transverse direction, and a plurality of laser radars 4 are evenly arranged in the transverse direction on the mounting rod 18, and the emitting end of the laser radar 4 faces downward. As a specific implementation, four laser radars 4 are evenly arranged in the transverse direction on the mounting rod 18 described in this embodiment. When the cage car 6 is connected to the first vertical frame 13 through a locking mechanism, the laser radar 4 is located at the front side of the cage car 6, and is used to detect obstacles in front of the cage car 6. An alarm is provided on the main frame (not shown in the figure). When the laser radar 4 detects an obstacle, the alarm sounds an alarm reminder.

[0046] Higher obstacles can be detected by the laser radar 4, and shorter obstacles can be observed by the camera 3. The two work together to provide enhanced audio-visual warning perception of hidden dangers in the operation of the cage truck 6, complement blind spots, and provide more comprehensive safety protection.

[0047] Furthermore, if Figure 1 As shown, an electrical cabinet 5 is disposed between the two second upright frames 17 on the bottom frame 11, and the display 2 is disposed on the electrical cabinet 5. Preferably, the electrical cabinet 5 is provided with a first inclined surface 51 facing upward and backward, and the display 2 is disposed on the first inclined surface 51.

[0048] Furthermore, the alarm (not shown in the figure) is arranged on the electrical cabinet 5.

[0049] Furthermore, the second stand 17 is provided with a handle 19, and when the operator holds the handles 19 on both sides with both hands, the display 2 is located in front of the operator. Preferably, the second stand 17 is provided with a second inclined surface 172 flush with the first inclined surface 51, and the handle 19 is provided on the second inclined surface 172.

[0050] When in use, first move the cage trolley 6 running safety auxiliary device to the rear side of the cage trolley 6 to be transported, then pull the pull rod 164 backward to open the locking mechanism, and at the same time continue to move the cage trolley 6 running safety auxiliary device forward until the cross bar 161 of the cage trolley 6 running safety auxiliary device abuts against the cage trolley 6. Then release the pull rod 164, as shown in FIG. Fig. 9 and Fig.10 As shown, at this time, the claw 1621 will be reset under the action of the elastic restoring force of the torsion spring 1623, and hooked on the vertical rods 61 on both sides of the rear of the cage car 6, completing the connection between the cage car 6 operation safety auxiliary device and the frame of the cage car 6. Then push the cage car 6 operation safety auxiliary device. Since the cage car 6 operation safety auxiliary device is already connected to the cage car 6 at this time, it can drive the cage car 6 to move together while pushing the cage car 6 operation safety auxiliary device. In the process of moving, the camera 3 and the laser radar 4 can detect the situation around the cage car 6 to avoid collision with staff, other cage cars 6, walls or fire-fighting facilities. When the cage car 6 is transported to the designated location, pull the pull rod 164 backwards again to open the locking mechanism, and at the same time pull the cage car 6 operation safety auxiliary device backwards to separate it from the cage car 6.

[0051] Furthermore, in order to avoid a rigid collision with the cage car 6 when the cage car 6 is hooked, as Figure 7 As shown, a buffer pad 1611 is provided on the front side of the cross bar 161. Exemplarily, the buffer pad 1611 is fixedly connected to the cross bar 161 by gluing.
