[0055] As shown in the figure, Figure 2 The bottom of each of the two moving plates 57 is connected with two supporting plates 58, a rotating shaft 59 is rotatably installed between the two supporting plates 58, the first end of the rotating shaft 59 extends to the outside of one of the supporting plates 58, a gear disc 511 is connected to the end surface of the extending part of the rotating shaft 59, a camera holder 513 is fixedly sleeved on the outer circumferential surface of the part of the rotating shaft 59 between the two supporting plates 58, the camera 510 is installed in the corresponding camera holder 513, two racks 512 are connected to the second housing 51, the rack 512 and the gear disc 511 are in one-to-one correspondence, the gear disc 511 is adapted to move along with the corresponding moving plate 57, thereby being engaged with the corresponding rack 512, so as to drive the corresponding camera holder 513 to produce an angular offset, and the rack 512 is located above the corresponding gear disc 511.

[0056] As shown in the figure, Figure 2As shown, the two moving plates 57 are respectively provided with lighting components 6, which include mounting plates 61 connected with the corresponding moving plates 57 and two lighting lamps 62 mounted on the corresponding mounting plates 61 and located on the two sides of the corresponding moving plates 57.

[0057] The working principle of the embodiment is as follows:

[0058] The gantry plays a supporting role in the whole device and can be moved through the universal wheels 14 arranged at the bottom. The electric hoist 2 on the gantry is arranged on the I-shaped cross beam 11 to move horizontally. The electric hoist 2 moves linearly in the slot of the I-shaped cross beam 11 through the action wheels, which is the prior art, and its working principle will not be described in detail. Through the position adjustment of the universal wheels 14 and the electric hoist 2 itself, the electric hoist 2 can be accurately moved above the object to be lifted. Taking the water pump in the well as an example, the electric hoist 2 is moved above the well, and then the steel wire rope is lowered so that the lighting component 6, the camera component 5 and the two hooks 45 connected to the steel wire rope are all inserted into the well. The lowering and lifting of the steel wire rope by the electric hoist 2 are both the prior art, and their working principles will not be described in detail.

[0059] When the lighting component 6, the camera component 5 and the two hooks 45 are all inserted into the well, the lighting lamps 62 in the lighting component 6 play a role in illuminating the working environment in the well, and the camera 510 in the camera component 5 can feed back the working picture at and around the hooks 45 to the display of the operator on the ground, thereby improving the ability to obtain information in the well and facilitating the accurate hanging of the two hooks 45 on the hoisting belt or the component such as the ring provided in advance on the object to be lifted or self-provided on the object to interface with the hooks 45. It should be noted that the lighting lamps 62 and the camera 510 are both provided with power sources, and their working principles are both the prior art, which will not be described in detail.

[0060] The operator can accurately see the positional relationship of the two hooks 45 and the corresponding docking components such as the lifting belts with the help of the camera 510 and the illuminating lamp 62. When the distance between the two hooks 45 is greatly different from the distance between the corresponding two lifting belts and cannot be normally docked, the driving motor 42 is started to drive the first bidirectional screw rod 43 to rotate. When the first bidirectional screw rod 43 rotates, the two transmission sleeves 44 connected with the first bidirectional screw rod 43 drive the corresponding hooks 45 to move towards or away from each other. The movement towards or away from each other is controlled through the forward and reverse rotation of the driving motor 42. According to the actual situation, the corresponding operation is selected to adjust the distance between the two hooks 45 to match the distance between the two lifting belts, so that the two lifting belts can be hung. It should be noted that the bidirectional screw rod and the transmission sleeve 44 can be assembled through a ball nut. The bidirectional screw rod drives the two transmission sleeves 44 to move towards or away from each other, which is prior art. The specific working principle is not described in detail here.

[0061] When the distance between the two hooks 45 is small, it indicates that the size of the object to be lifted is small, so the distance between the two cameras 510 is also small, avoiding the situation that the small size of the object and the too large field of view range cause the details to be unclear. When the distance between the two hooks 45 is large, it indicates that the size of the object to be lifted is large, so the distance between the two cameras 510 also needs to be large to widen the field of view range. Therefore, the adjustment of the distance between the cameras 510 needs to be synchronized with the adjustment of the distance between the hooks 45. The specific synchronous movement mode is that the first bidirectional screw rod 43 drives the distance between the two hooks 45 to change through rotation. In this process, the first bevel gear 52 connected with the first bidirectional screw rod 43 rotates, the first bevel gear 52 drives the second bevel gear 53 to rotate through meshing, the second bevel gear 53 and the third bevel gear 54 are fixedly connected through a rotating rod, so the second bevel gear 53 can drive the rotation of the second bevel gear 53, and the third bevel gear 54 drives the fourth bevel gear 55 to rotate through meshing. Since the fourth bevel gear 55 is fixedly sleeved on the second bidirectional screw rod 56, the rotation of the fourth bevel gear 55 can realize the rotation of the second bidirectional screw rod 56. When the second bidirectional screw rod 56 rotates, it drives the two moving plates 57 connected with the cameras 510 to move towards or away from each other. The transmission mode between the first bidirectional screw rod 43 and the moving plate 57 is the same as the transmission mode between the first bidirectional screw rod 43 and the transmission sleeve 44. It needs to be explained that the towards or away from each other movement of the two moving plates 57 is consistent with the towards or away from each other movement of the two transmission sleeves 44, that is, when the two transmission sleeves 44 move towards each other, the two moving plates 57 also move towards each other. At the same time, the cameras 510 and the adjacent hooks 45 are arranged in a staggered manner to avoid the hooks 45 and the lifted object from blocking the field of view of the cameras 510. The moving plate 57 also drives the mounting plate 61 connected thereto to move while moving. Each mounting plate 61 is provided with two illuminating lamps 62, and the two illuminating lamps 62 are located on both sides of the moving plate 57, that is, on both sides of the corresponding camera 510. The synchronous movement of the illuminating lamps 62 with the cameras 510 continuously improves the illumination and avoids the direct light of the lens;

[0062] When the moving plate 57 moves, the gear plate 511 connected to the rotating shaft 59 between the two supporting plates 58 will mesh with the gear rack 512 connected to the second shell 51, the gear rack 512 drives the gear plate 511 to rotate, the gear plate 511 drives the rotating shaft 59 to rotate, the rotating shaft 59 drives the camera holder 513 to rotate, and the camera 510 is installed in the camera holder 513, so that the angle of the camera 510 can be changed. It should be noted that the gear rack 512 is located above the gear plate 511, so that the camera 510 can be inclined downward toward the side of the hook 45, and a larger field of view can be obtained by changing the angle of inclination, which is more conducive to hoisting a water pump with a larger size in the well.

[0063] The telescopic support frame 13 can be provided in two sections in a conventional manner, but is not limited to this arrangement. When provided in two sections, one section is a fixed end and the other section is a telescopic end. The fixed end is hollow, and the telescopic end can be telescoped in the internal space of the fixed end to adjust the total length. After adjustment, the fixed end and the telescopic end are fixed by bolts passing through the preset adjustment holes. The telescopic support frame 13 is a prior art and will not be described in detail here.

[0073] On the basis that the first connecting beam 15 or the second connecting beam 16 is butted with the connecting seat 12 through the fixing groove 114, two connecting plates 112 are arranged on the connecting seat 12, a sliding rod 110 is arranged between the two connecting plates 112, a screw thread is arranged on the outer circumferential surface of the sliding rod 110, a fastening nut 111 is threadedly connected on the screw thread part, and the first connecting beam 15 or the second connecting beam 16 slides to adjust the position on the corresponding connecting seat 12, and the sliding rod 110 slides in the horizontal adjusting groove 19, when the position is adjusted, the two fastening nuts 111 are rotated to move on the sliding rod 110, and finally the two fastening nuts 111 clamp the two sides of the horizontal adjusting groove 19 in a clamping manner, so that the fixing capacity of the first connecting beam 15 and the second connecting beam 16 with the corresponding connecting seat 12 is further improved, when different sizes of the first connecting beam 15 and the second connecting beam 16 need to be replaced, the connecting plate 112 is disconnected with the connecting seat 12, and then the connecting plate 112 is disconnected with the sliding rod 110, so that the corresponding connecting beam can be taken out, and in this way, the width of the whole gantry frame is changed.
