Description

Technical Field

[0001] This invention relates to a testing device, and more particularly to a winch cable tension testing device. Background Technology

[0002] Marine cable winches are equipped with a cable guide mechanism on their frame. This mechanism forces the cable to move laterally or backward during winding or unwinding, facilitating its orderly winding and arrangement on the drum. The cable is under tension during winding or unwinding, or when the winch is stationary. Existing cable guide mechanisms are limited in function, only controlling the cable's left-right swing to complete the winding or unwinding actions; they cannot detect the cable tension in a timely or real-time manner. Summary of the Invention

[0003] The purpose of this invention is to provide a winch cable tension detection device that is simple in structure, flexible and reliable in operation, and can detect the tension of the cable in real time while winding and unwinding the cable, thus overcoming the shortcomings of the prior art.

[0004] The winch cable tension detection device of the present invention includes a cable laying mechanism and a three-roller force measuring mechanism. The cable laying mechanism includes a bracket with a reciprocating screw rotatably connected and a guide shaft slidably connected. The force measuring mechanism includes a force measuring bracket and three rotatable rollers mounted on the force measuring bracket, one of which has a pin-shaft sensor as its spindle. The bracket is rotatably connected to a rotating bracket via two vertical shafts symmetrically arranged at the upper and lower ends of the rotating bracket and the bracket. A swing link is rotatably connected to the middle of the rotating bracket via two horizontal shafts symmetrically arranged on both sides of the rotating bracket and the swing link. The swing link is rotatably connected to the force measuring bracket in the force measuring mechanism via two connecting shafts symmetrically arranged on both sides of the swing link and the force measuring bracket.

[0005] In the winch cable tension detection device of the present invention, during installation, the pin sensor in the three-roller force measuring mechanism is connected to the control mechanism, and the cable is wound on the winch drum through the three-roller force measuring mechanism, the swinging connecting rod, the rotating bracket, and the bracket. During operation, the reciprocating screw mounted on the frame rotates under the drive of the drive mechanism, simultaneously driving the bracket to reciprocate. The rotating support, swing link, and three-roller force measuring mechanism (including the force measuring bracket) also reciprocate accordingly. The cable passes through the three-roller force measuring mechanism, the swing link, the rotating support, and the bracket, all reciprocating. During this reciprocating motion, because the bracket and rotating support, the rotating support and the swing link, and the swing link and the force measuring bracket are all rotatably connected, the rotating support can rotate left and right, the swing link can swing up and down, and the force measuring bracket can swing up and down. This allows the force measuring mechanism to freely float up and down and swing left and right, following the changes in the position and angle of the cable during winding and unwinding. Combined with the reciprocating motion of the bracket, this ensures the cable is neatly wound and arranged on the drum. The cable tension can be measured in real time via the three-roller force measuring mechanism during the operation and stop of the cable winch, determining the winch's load status and effectively avoiding safety hazards.

[0006] Figure 1 This is a three-dimensional structural diagram of a specific embodiment of the present invention. Detailed Implementation

[0007] like Figure 1 As shown: The winch cable tension detection device of the present invention includes a cable laying mechanism and a three-roller force measuring mechanism. The cable laying mechanism includes a bracket 2, on which a reciprocating screw 3 is rotatably connected and a guide shaft 4 is slidably connected. The force measuring mechanism includes a force measuring bracket 11 and three rotatable rollers mounted on the force measuring bracket 11. The spindle of one roller is a pin sensor 10, and the other two rollers are mounted on the force measuring bracket 11 through a first roller shaft 9 and a second roller shaft 12, respectively.

[0008] The bracket 2 is rotatably connected to the rotating support 6 via a vertical shaft 1. There are two vertical shafts 1, which are symmetrically arranged at the upper and lower ends of the rotating support 6 and the bracket 2. A swing link 7 is rotatably connected to the middle of the rotating support 6 via a horizontal shaft 5. There are two horizontal shafts 5, which are symmetrically arranged on both sides of the rotating support 6 and the swing link 7. The swing link 7 is rotatably connected to the force measuring support 11 in the force measuring mechanism via a connecting shaft 8. There are two connecting shafts 8, which are symmetrically arranged on both sides of the swing link 7 and the force measuring support 11.

[0009] In the winch cable tension detection device of the present invention, during installation, the pin sensor 10 in the three-roller force measuring mechanism is connected to the control mechanism, and the cable 13 is wound on the winch drum through the three-roller force measuring mechanism, the swing connecting rod 7, the rotating bracket 6, and the bracket 2. During operation, the reciprocating screw 3 mounted on the frame rotates under the drive of the drive mechanism, simultaneously driving the bracket 2 to reciprocate. The rotating support 6, the swinging link 7, and the three-roller force measuring mechanism including the force measuring bracket reciprocate accordingly. The cable 13 passes through the three-roller force measuring mechanism, the swinging link 7, the rotating support 6, and the bracket 2, and reciprocates accordingly. During the reciprocating swing, since the bracket 2 and the rotating support 6, the rotating support 6 and the swinging link 7, and the swinging link 7 and the force measuring bracket 11 are all rotatably connected, the rotating support 6 can rotate left and right, the swinging link 7 can swing up and down, and the force measuring bracket 11 can swing up and down, the force measuring mechanism can freely float up and down and swing left and right as the position and angle of the cable 13 changes during the cable winding and unwinding process, and cooperate with the reciprocating motion of the bracket 2 to make the cable 13 neatly arranged and wound on the drum. The cable 13 is arranged, wound, or unwound on the cable drum in coordination with the reciprocating motion of the bracket. The cable tension can be measured in real time by a three-roller force measuring mechanism when the cable winch is running and stopping, thus determining the load status of the winch and effectively avoiding safety hazards.
