Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings.

Example 1

A movable arm tower crane hook video monitoring device is shown in figures 1-5 and comprises an L-shaped plate 2, a socket 3, a rack 4, a shell 41, a camera 5, a sealing mechanism 6, a guide sleeve 7, a movable clamping rod 8 and a wedge block 9, wherein the shell 41 is fixedly connected to the upper portion of the left side face of the camera 5, an arc-shaped groove 51 is formed in the upper portion of the left side of the shell 41, the sealing mechanism 6 is arranged in the shell 41, the guide sleeve 7 is fixedly connected between the upper portions of the front side face and the rear side face in the shell 41, the movable clamping rod 8 is arranged in the guide sleeve 7 in a sliding mode, the wedge block 9 matched with the sealing mechanism 6 is fixedly connected to the bottom end of the movable clamping rod 8, the socket 3 is fixedly connected to the middle of the right side face of the L-shaped plate 2, the socket 3 is matched with a plug of the camera 5, and the rack 4 matched with the sealing mechanism 6 is fixedly connected to the front side and the rear side of the right bottom outside the L-shaped plate 2.

Closing mechanism 6 is including gear 61, the pivot 62, connecting plate 63, cowl 64 and actuating lever 65, the cross-under of casing 41 front and back both sides right part downside all the rotary type has

pivot

62, 62 outer ends rigid couplings of pivot have gear 61, gear 61 and rack 4 cooperation, 62 inboard week of pivot 62 left parts rigid couplings have connecting plate 63, the rigid couplings have cowl 64 between the front and back both sides connecting plate 63 left end, cowl 64 and arc wall 51 cooperation, the rigid couplings have actuating lever 65 in the middle of cowl 64 medial surface left side lower part, actuating lever 65 and wedge 9 cooperation.

Firstly, an operator installs a camera 5 on a lifting hook of a suspension arm, installs an L-shaped plate 2 at the right side of the bottom of the suspension arm, clamps a plug of the camera 5 at the top end of a movable clamping rod 8, starts the camera 5, and can shoot an image transmitted back through the camera 5 to control the lifting hook of the suspension arm to hook an object, a closing mechanism 6 is matched with a shell 41 to block the plug of the camera 5, so that rainwater and impurities are prevented from falling onto the plug to affect use, when the camera 5 is powered off for a long time, the operator can control the lifting hook of the suspension arm to move upwards to drive the camera 5 to move upwards, the camera 5 moves upwards to drive the shell 41 to move upwards, the shell 41 moves upwards to drive the movable clamping rod 8 to move upwards through a guide sleeve 7, the movable clamping rod 8 moves upwards to drive the plug to move upwards, and when the closing mechanism 6 moves upwards to contact with a rack 4, the rack 4 makes the closing mechanism 6 function and does not block the arc-shaped groove 51, also do not block the plug, and simultaneously, closing mechanism 6 function and wedge 9 contact, and closing mechanism 6 drives wedge 9 rebound, and wedge 9 rebound drives movable kelly 8 rebound, and movable kelly 8 rebound drives plug rebound and passes arc-shaped groove 51, and the plug passes arc-shaped groove 51 and inserts circular telegram in socket 3, just also charges camera 5, and the lifting hook stop motion of control davit, and closing mechanism 6 also stops the function. Similarly, when the lifting hook of davit moves down and begins to work, the plug then moves down and breaks away from with socket 3, camera 5 stops to charge, and then closing mechanism 6 moves down and resets through the function of rack 4, and closing mechanism 6 resets and breaks away from with wedge 9, and because of the effect of gravity, wedge 9 drives the plug through activity kelly 8 and moves down to casing 41 in, and closing mechanism 6 blocks arc 51, and closing mechanism 6 continues to move down and breaks away from with rack 4. Thus, when the camera 5 is not powered, the lifting hook of the suspension arm can be controlled to enable the plug to be plugged into the socket 3 to be powered on to charge the camera 5.

When the housing 41 moves upwards, the housing 41 drives the rotating shaft 62 to move upwards, the rotating shaft 62 moves upwards to drive the gear 61 and the connecting plate 63 to move upwards, the connecting plate 63 moves upwards to drive the arc-shaped baffle 64 to move upwards, and further when the gear 61 moves upwards to be meshed with the rack 4, the rack 4 enables the gear 61 moving upwards to rotate reversely, the gear 61 rotates reversely to drive the rotating shaft 62 to rotate reversely, the rotating shaft 62 rotates reversely to drive the arc-shaped baffle 64 to rotate reversely through the connecting plate 63, the arc-shaped baffle 64 rotates reversely without blocking the arc-shaped slot 51, the arc-shaped baffle 64 also drives the driving rod 65 to rotate reversely, the driving rod 65 rotates reversely to be in contact with the wedge 9, the driving rod 65 drives the wedge 9 to move upwards, so that the plug passes through the arc-shaped slot 51 to be inserted into the socket 3, the lifting hook of the control boom stops driving the housing 41 to move, the gear 61 also stops moving upwards and rotates reversely, and the arc-shaped baffle 64 stops rotating. When the lifting hook of the suspension arm moves downwards to start working, the shell 41 moves downwards to drive the rotating shaft 62 to move downwards, the gear 61 rotates forwards through the rack 4, the arc-shaped baffle plate 64 rotates forwards to drive the driving rod 65 to rotate forwards to be separated from the wedge-shaped block 9, the plug moves downwards into the shell 41, the arc-shaped baffle plate 64 rotates forwards to block the arc-shaped groove 51, and the gear 61 moves downwards continuously to be separated from the rack 4. Therefore, rainwater and impurities can be prevented from falling onto the plug to affect use.
