[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0031] See also Figure 1-2 As shown, the present invention is a security inspection equipment trolley working in a special environment, the security inspection equipment trolley comprises a trolley body 2, a mounting column 11 is arranged on the top of the trolley body 2, three cameras 12 are installed on one side of the mounting column 11, through the arrangement of the three cameras 12, the near and far focus cross-angle monitoring of the three cameras 12 is used to reduce the blind spot of the monitoring field of view; and in order to facilitate the installation of the prescribed route to keep the security inspection equipment trolley stable in use, a group of tracks 1 are arranged along the inspection route, and the trolley body 2 is controlled to move along the track 1 when in use.

[0032] Specifically, a processor connected to the camera 12 is disposed in the mounting column 11, and the processor is also connected to a light alarm 13 disposed on the mounting column 11; Figure 5 The trolley body 2 includes a frame 20 on which a moving mechanism 21 that moves along the track 1 is installed. The moving mechanism 21 is connected to a lead-acid battery 22 mounted on the frame 20; the lead-acid battery 22 is also electrically connected to the camera 12 and the light alarm 13.

[0033] It can be known that in the present invention, when three cameras 12 are used to detect a dangerous situation, in order to facilitate use and timely control the trolley body 2 to stop at the dangerous situation point according to needs, a braking mechanism that cooperates with the track mounting surface is also provided on the trolley body 2; the braking mechanism includes a counterweight friction block 6 that can move up and down; when a dangerous situation occurs, after the trolley body 2 moves to the dangerous position, the counterweight friction block 6 is controlled to fall and contact with the track mounting surface to control the trolley body 2 to brake.

[0034] Specifically, in a possible implementation, the brake mechanism further includes a driving mechanism for driving the counterweight friction block 6 to move up and down; Figure 8The driving mechanism includes at least two tubes 60 arranged on the trolley body 2, and a guide rod 61 is slidably arranged along the inner wall of any tube 60, and the top of the guide rod 61 is connected to a connecting rope A62, and the top of the connecting rope A62 is connected to the outer wall of the cross bar 63; a telescopic cylinder A64 is also arranged on the trolley body 2, and the end of the telescopic cylinder A64 is fixed with a V-shaped support block 65 supported on the outer wall of the cross bar 63; the bottom end of the guide rod 61 is connected to the counterweight friction block 6 through a connecting rope B69; guide sleeves 66 are respectively arranged on the trolley body 2 at both ends of the cross bar 63, and the bottom side surface of the guide sleeve 66 is connected to a plug sleeve 67 sliding along the inner wall of the guide sleeve 66 through a spring D; an opening is arranged on the bottom side surface of the guide sleeve 66, and the plug sleeve 67 is connected to a traction rope 671, which passes through the opening and is connected to a telescopic cylinder B68; that is, when it is necessary to control the counterweight friction block 6 upward in use, When it moves to the point where it leaves the track mounting surface, the control telescopic cylinder A64 is extended, thereby driving the cross bar 63 to move upward in the vertical direction. At this time, the movement of the guide rod 61 and the cooperation of the connecting rope A62 and the connecting rope B69 are used to drive the counterweight friction block 6 to move upward. After moving to the specified position, the control telescopic cylinder B68 is extended. At this time, under the action of the spring D, the control sleeve 67 is extended outward until the two ends of the cross bar 63 are respectively inserted into the two sleeves 67, and the control telescopic cylinder A64 is retracted; on the contrary, when the counterweight friction block 6 needs to move downward to contact the track mounting surface, the control telescopic cylinder B68 is retracted to drive the two ends of the control cross bar 63 to be pulled out of the two sleeves 67 respectively. At this time, under the action of gravity, the counterweight friction block 6 quickly moves downward until it contacts the track mounting surface, which is beneficial for the track mounting surface and the counterweight friction block to form damping and thus prevent the trolley body 2 from continuing to move under the action of inertia.

[0035] In order to detect whether the counterweight friction block 6 contacts the track mounting surface after release during use, a friction plane that matches the track mounting surface is provided on one side of the counterweight friction block 6; a contact detection module is provided on the friction plane; Fig. 9 The contact detection module includes a groove 601 opened on the friction plane, and a limit ring 602 is set at the open end of the groove 601; the inner wall of the limit ring 602 is connected to the T-shaped movable rod 604 through a spring E603, and a pressure sensor B605 is set on the bottom side of the groove 601.

[0036] Specifically, the processor is also connected to the factory monitoring system through a wireless transceiver module.

[0037] Similarly, during use, the space in which the track 1 is installed is accompanied by continued production, and other equipment or personnel pass by, which may easily cause the track 1 to be damaged. When the track 1 is damaged, the trolley body 2 moves past the damaged position of the track 1, which may easily cause the trolley body 2 to detach from the track 1. The cross section of the track 1 provided by the present invention is triangular, and a detection mechanism for detecting whether the track 1 located at the front side of the movement of the trolley body 2 is damaged is provided at the front end of the trolley body 2; Figure 3-4 The detection mechanism includes a swing arm 3 hinged on the trolley body 2, and a detection module is installed at the end of the swing arm 3; the detection module includes an inverted V-shaped block 31 connected to the end of the swing arm 3, and pressure sensors A32 are respectively arranged on the two side walls of the V-shaped block 31, and an outer guide sleeve 33 is arranged on the peripheral side of the pressure sensor A32, and a convex ring 34 is arranged on the inner side wall of the outer guide sleeve 33. One side of the convex ring 34 is connected to a movable column 36 that slides along the inner wall of the outer guide sleeve 33 through a spring A35, and a ball 37 that moves along the track 1 is installed at the end of the movable column 36; the other end of the movable column 36 is connected to a A guide column 39 slides through the convex ring 34, and a limit plate 30 is set at the end of the guide column 39. Then, when the track 1 is damaged, the track 1 is lost, or depressions or protrusions are formed on both sides of the track 1; that is, when the detection mechanism moves to the damaged position of the track 1, the pressure signal generated by the pressure sensor A32 changes, that is, when the pressure value detected by the pressure sensor A32 fluctuates greatly compared with the pressure value detected under normal conditions, that is, at this time, the surface track 1 is damaged; and then the trolley body 2 is controlled to stop in advance to avoid the trolley body 2 from tipping over when it moves past the damaged position of the track 1.

[0038] Specifically, the swing arm 3 swings along the horizontal plane when in use; the end bottom side of the swing arm 3 is connected to a connecting rod assembly 4, such as Figure 7 The end of the connecting rod assembly 4 is connected to the outer wall of the V-block 31; and the connecting rod assembly 4 includes a sleeve 40 connected to the side of the end of the swing arm 3, and the sleeve 40 is provided with a column A41 and a column B43 that move along its inner wall, and a spring C42 is connected between the column A41 and the column B43; the bottom end of the sleeve 40 is provided with a locking bolt 44 for locking and fixing the column A41 located in the sleeve 40.

[0039] It can be known that when using Figure 6An infrared thermal imager assembly 14 is also arranged on the top of the mounting column 11. The infrared thermal imager assembly 14 includes a column 141 fixed on the top of the mounting column 11. A connecting sleeve A142 is arranged on the column 141. A base 143 with a pivot shaft is arranged on the end of one side of the connecting sleeve 142. A connecting sleeve B144 is pivotally connected to the pivot shaft. A hinge seat A145 is arranged on one side of the connecting sleeve B144. A hinge seat B146 is hinged on one side of the hinge seat A145 through a hinge shaft. The end of the hinge seat B146 is connected to a mounting plate 147. An infrared thermal imager body 148 is installed on the mounting plate 147. The above arrangement is used to facilitate the adjustment of the installation direction of the infrared thermal imager body 148 according to needs during use.
