TECHNICAL FIELD
[0001] The utility model belongs to the field of hanging element, concretely, especially relates to a small -size water equipment hoist hook device of safety tongue piece dynamic adjustment. BACKGROUND
[0002] When hoisting water operation equipment, the ship is usually equipped with a large crane fixed on the deck to carry out hoisting operation. But in the offshore, inland river and other places, some small water equipment is often needed to carry out related operations on the water surface. For example, underwater robots (ROV) are used to carry out bridge detection, and underwater submersible vehicles (AUV) are used to carry out underwater pipeline detection. At the same time, due to the limitation of operation cost, water area characteristics and other factors, the ship loaded with large crane is difficult to enter or stop operation, and is generally not adopted. Considering that the weight of such small water equipment is generally between 50-200kg, the weight is relatively light, and only a small crane is needed to lift and lower, so a small ship is generally used, and an independent crane is used for temporary hoisting operation.
[0003] The safety tongue piece is generally installed on the hook of the temporary crane, and is self-locked by spring contraction. When the equipment shakes during hoisting, it can play a good blocking effect. But in actual use, when hoisting small water equipment to the outside of the ship side, if there is no receiving personnel on the water surface to operate, the automatic locking feature of the safety tongue piece becomes an obstacle to the equipment unhooking. Some operators also use straps and bands to bind the safety tongue piece on the hook body during actual operation, so that it is always in an open state, but this will cause the safety tongue piece to lose its function and it is difficult to ensure the safe hoisting of the equipment when it shakes. There are also a small part of cranes on the market equipped with hooks that control the opening and closing of the safety tongue piece through motors, electromagnets and other devices, but such products are expensive, have high power and need regular maintenance, and have low cost performance in the field environment without fixed power supply. In addition, once the equipment is lifted, it is basically in a suspended state, and there is also a lack of corresponding adjustment capability for some equipment that needs to be simply adjusted in water angle and direction. There is usually a large height difference between the ship and the water surface, and it is difficult to directly adjust the hook or unhook the operation by manual. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described in the following combined with the drawings in the embodiments of the utility model, obviously, the described embodiments are only some embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.
[0024] In the description of the utility model, it is understood that the terms "opening", "upper", "lower", "top", "middle", "inner" and the like indicate the orientation or positional relationship, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated component or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.
[0025] Please refer to Figures 1-4 As shown in the utility model is a kind of small water equipment hoist hook device with dynamic adjustment safety tongue, including hook body 1, safety tongue 2 and tongue restriction control device 3, hook body 1 is installed on small crane by wire rope, safety tongue 2 is rotatably installed in the inside of the opening of hook body 1 by spring hinge shaft, tongue restriction control device 3 includes restriction coil 4, connecting rod 5, pull rope 6, tension reset spring 7 and compression handle 8, restriction coil 4 is connected with hook body 1 and safety tongue 2, compression handle 8 is installed at one end of connecting rod 5, and compression handle 8 is connected with restriction coil 4 by pull rope 6, and tension reset spring 7 is used to drive pull rope 6 to move reset;
[0026] When the hook device is used, the small water equipment is fixed and tightened by using the sling, the operator holds the compression handle 8, and the pull rope 6 is pulled to the side of the operator's body by the compression handle 8, at this time, the pull rope 6 drives the restriction coil 4 to contract, so that the restriction coil 4 is contracted and tightened, and the safety tongue 2 is opened under the action of the restriction coil 4;The sling for binding the small water equipment is sleeved into the opened hook body 1 of safety tongue 2, the tension of pull rope 6 is released, and the pull rope 6 is reset under the reset elastic force of tension reset spring 7, so as to relax the contraction force of restriction coil 4, and then the safety tongue 2 is rotated and reset and closed under the torsional elastic force of spring hinge shaft;The crane hoists the equipment to the outside of the ship side, and lowers the equipment to the water surface, the operator holds the connecting rod 5, and opens the safety tongue 2 again by the cooperation of the compression handle 8 and the pull rope 6, adjusts the orientation position of the equipment by using the rigid connecting rod 5, and challenges downward to make the sling separate from the hook;When the equipment is recovered, the operator holds the connecting rod 5 and opens the safety tongue 2 again, and uses the bracing rod and other tools to lift the sling and sleeve it into the hook body 1, and hoists the equipment back to the ship.
[0027] Specifically, the connecting rod 5 is a hollow rod structure, the constraint coil 4 is a flexible metal strip, and the constraint coil 4 is connected with the fixed connecting head 10 and the movable connecting head 11 respectively. The fixed connecting head 10 is fixedly installed at the end of the connecting rod 5, and the movable connecting head 11 is connected with one end of the pull rope 6. The other end of the pull rope 6 passes through the connecting rod 5 and is connected with the compression handle 8. When the pull rope 6 pulls the constraint coil 4 through the movable connecting head 11, the constraint coil 4 is gradually contracted, so that the safety tongue 2 is pulled and opened by the tightening force of the constraint coil 4. When the pull rope 6 is relaxed and reset, the constraint coil 4 is flexibly deformed and reset under the action of its own elasticity, and no longer pulls the safety tongue 2, so as to facilitate the reset of the safety tongue 2.
[0028] Specifically, the compression handle 8 includes a handle body, and outer ring guide grooves 14 are formed on both sides of the handle body. A T-shaped handle 13 is slidably installed between the two outer ring guide grooves 14. One end of the T-shaped handle 13 is connected with the pull rope 6. When the pull rope 6 needs to be pulled, the palm holds the handle body of the compression handle 8, and the fingers hold the T-shaped handle 13 tightly and push it backward. The T-shaped handle 13 can pull the pull rope 6 backward, so that the pulling process of the pull rope 6 is more convenient.
[0029] Specifically, a limiting plate 12 is fixedly installed in the connecting rod 5, and a tension reset spring 7 is arranged in the connecting rod 5. One end of the tension reset spring 7 is fixedly connected with the limiting plate 12, and the other end of the tension reset spring 7 is fixedly connected with the T-shaped handle 13. When the T-shaped handle 13 is held tightly and pushed backward, the tension reset spring 7 is stretched and elongated, and generates a reset elastic force. When the holding of the T-shaped handle 13 is relaxed, the tension reset spring 7 pulls the T-shaped handle 13 to reset, thereby driving the pull rope 6 to reset.
[0030] Specifically, a handle reset spring 15 is installed in the outer ring guide groove 14 and abuts against the rear end of the T-shaped handle 13. When the T-shaped handle 13 is held tightly and pushed backward, the handle reset spring 15 is abutted and contracted to generate a reset elastic force. When the holding of the T-shaped handle 13 is relaxed, the handle reset spring 15 pushes the T-shaped handle 13 to move and reset. The tension reset spring 7 and the handle reset spring 15 jointly drive the T-shaped handle 13 to reset, so that the reset process of the T-shaped handle 13 is more smooth.
[0031] Specifically, a constraint port 9 is formed on the hook body 1 and the safety tongue 2, and the constraint coil 4 passes through the two constraint ports 9 in sequence. The constraint coil 4 is constrained and limited by the constraint port 9, so that the installation and operation of the constraint coil 4 are more stable, and it is ensured that the constraint coil 4 can drive the safety tongue 2 to open when it is contracted.
