Camera 1, camera 2, camera 3, camera 4 are used for the real-time situation of four direction obstacles of surveillance valve room high altitude vehicle chassis 9 respectively, and head end laser radar 5 and tail end laser radar 6 are accurate survey and drawing valve room high altitude vehicle and the accurate distance of obstacle respectively. And after the set warning distance is reached, displaying the position and the distance of the detected obstacle on a display screen. The power supply device 7 is installed near the charging device of the valve hall overhead truck, and is convenient to charge simultaneously with the vehicle after the operation is finished.
And then will use removable mount pad when needs installation and dismantlement camera or laser radar, the use is as follows:
the base body (10) is fixed at the corresponding position of a vehicle chassis (9) firstly, because the base body (10) does not need to be moved after being installed, the existing bolt or welding or other modes capable of being firmly fixed can be adopted, if the base body (10) is installed on a plane, the bottom surface of the base body (10) is connected with an installation surface, and if the base body (10) is installed on a vertical surface, the rear end surface of the base body (10), namely the right side end surface shown in figure 2, is fixedly connected with the installation vertical surface. When the base is installed by bolts, the bottom surface or the rear end surface of the base body (10) is provided with a bottom edge of an outer edge, and a hole for the bolt to pass through is arranged on the bottom edge (because the prior art is adopted, the hole is not shown in the figure). The plane or the vertical surface is the position for mounting on a trolley, and the front end and the rear end of the trolley are provided with the plane or the vertical surface for mounting.
When the base body (10) is installed, the replaceable installation base can be normally used, the initial state of the replaceable installation base is as shown in figure 7, if a laser radar needs to be installed, the laser radar is placed below the arc-shaped elastic sheet (20) shown in figure 2, namely, the part A in figures 3 and 7, then the connecting rod (21) is pulled forwards, namely, the connecting rod (21) is pulled anticlockwise as shown in figure 2, meanwhile, the movable clamp (12) is pinched open until the front ends of the two clamping pieces (12-1) of the movable clamp (12) are positioned at the two sides of the 7-shaped pressing piece (11), namely, the position shown in figure 3, then the two clamping pieces (12-1) are loosened to clamp the laser radar from the two sides, in the process, due to the anticlockwise rotation of the driving gear (16), the replaceable installation base is enabled to be meshed with the horizontal rack (10-2) to move backwards, namely, the front lateral rack (10-1) is driven to move backwards together by moving to the right end shown in figure 2, so that the front lateral rack (10-1) is meshed with the transverse gear (14) to rotate, the transverse gear (14) drives the internal threaded sleeve (13) to rotate, the internal threaded sleeve (13) is meshed with the external threaded screw rod (11-1-1) to rotate, because the internal threaded sleeve (13) is fixed up and down, the external threaded screw rod (11-1-1) drives the 7-shaped pressing piece (11) to move downwards and press on the laser radar from the upper part, thus the laser radar is fixed from three directions, then the transverse insert piece (17-1) is inserted into the groove (18-1) and the slide block (19) is moved forwards to cover the transverse insert piece (17-1), as shown in figure 6, so that the fixed support rod (17) and the support column movable clamp (12) are prevented from moving upwards and falling off.
When the laser radar needs to be disassembled, the sliding block (19) is slid backwards, then the fixed supporting rod (17) is moved out, the movable clamp (12) is pinched, the connecting rod (21) is pulled to rotate clockwise, the laser radar is separated from the laser radar, meanwhile, the transverse gear (14) is meshed and rotates reversely, so that the 7-shaped pressing piece (11) moves upwards until the state shown in the figure 7 is reached, and then the laser radar is taken out to be replaced or maintained. Because the volume and the weight of laser radar or camera are not very big, so through the tight location of the clamp of three direction just can be fine fixed with it, the reliability is very high, and its use is very convenient, fine solution bolt fastening's installation dismantle complicated problem and the unstable problem of sucking disc fixed, do benefit to popularization and application.
