[0002] With the rapid growth of shipbuilding in China, the renewal and upgrading of ship equipment are getting faster and faster, and the testing and inspection of equipment performance are becoming more and more important. Especially for equipment such as ship capstans, winches, and towing winches, it is necessary to measure the tensile force of the equipment and at the same time detect the lifting speed, and it is necessary to conduct both static and dynamic tests of the ship. To quickly complete the testing and inspection of such equipment, a tensile test tooling is required.

[0003] Generally, to measure the tensile force and lifting speed of such equipment, a crane is needed for cooperation, and a pulley is hung on the hook for testing and inspection, or a tooling pulley is welded on the ship deck and extended outside the ship deck for testing and inspection. Since such tests require a large number of test times and a long cycle, the former method has a long cooperation cycle and high cost, and the latter method damages the ship deck coating and internal decoration, etc., and the installation, welding and removal costs of the tooling are high and it cannot be reused. Moreover, the angle of the welded or ordinary detachable tooling relative to the ship is fixed, and when the ship state changes, it is necessary to adjust the ship state to meet the test requirements.

[0004] Therefore, it is urgent to research and develop a tensile test tooling that can be disassembled and turned to solve the deficiencies of the prior art. Content of the Utility Model

It also includes two fixed clamping plates, which are respectively clamped on both sides of the bollard of the ship. And the two fixed clamping plates are detachably connected by a plurality of fastening bolts so that the two fixed clamping plates are clamped on the bollard. An outer cylinder is fixedly installed on one of the fixed clamping plates, and the other fixed clamping plate is slidably sleeved on the outer cylinder. An inner cylinder is installed in the outer cylinder through a bearing. Both ends of the inner cylinder penetrate to the outside of both ends of the outer cylinder and are connected with gland plates. One of the gland plates is fixed at one end of the inner cylinder, and the other gland plate is detachably installed at the other end of the inner cylinder. The pulley is installed on the outside of one of the gland plates fixed to the inner cylinder. The steel wire rope is threaded through the pulley and the inner cylinder.

[0007] As a further improvement, the test object is a cast iron weight.

[0008] Further, the test object is connected to the steel wire rope through a bolt.

[0009] Further, the side wall of each fastening bolt is in contact with the side wall of the bollard.

[0010] Further, there are four fastening bolts in total, and the four fastening bolts are evenly distributed around the outer cylinder. Each fastening bolt passes through the two fixed clamping plates in sequence and is connected with a nut.

[0011] Further, the other gland plate is connected to the inner cylinder by a thread.

Among them, the test object 1 is connected to a steel wire rope 3 corresponding to a ship's windlass or capstan or towing winch. The tensile test tooling further includes two fixed clamping plates 4, which are respectively clamped on both sides of a bollard 5 of the ship, and the two fixed clamping plates 4 are detachably connected by a plurality of fastening bolts 6 so that the two fixed clamping plates 4 are clamped on the bollard 5. An outer cylinder 7 is fixedly installed on one of the fixed clamping plates 4, and the other fixed clamping plate 4 is slidably sleeved on the outer cylinder 7 to facilitate the removal of the other fixed clamping plate 4. An inner cylinder 9 is installed in the outer cylinder 7 through a bearing 8, so that the inner cylinder 9 can rotate relative to the outer cylinder 7. Both ends of the inner cylinder 9 penetrate to the outside of both ends of the outer cylinder 7 and are connected with gland plates 10. One gland plate 10 is fixed at one end of the inner cylinder 9, and the other gland plate 10 is detachably installed at the other end of the inner cylinder 9. It should be noted that the detachable gland plate 10 and the detachable fixed clamping plate 4 are on the same side, and the fixed gland plate 10 and the fixed fixed clamping plate 4 are on the same side. The pulley 2 is installed on the outside of one of the gland plates 10 fixed to the inner cylinder 9. Specifically, the pulley 2 is rotatably installed on a bracket, and the bracket is then fixed on the outside of the gland plate 10. The steel wire rope 3 passes through the pulley 2 and the inner cylinder 9 to realize the support of the steel wire rope 3.

[0022] The tensile test tooling of the utility model is clamped on the bollard 5 of the ship through two fixed clamping plates 4, and the pulley 2 is installed on the rotatable inner cylinder 9. During use, the two fixed clamping plates 4 are placed on both sides of the bollard 5, the outer cylinder 7 is inserted into the other fixed clamping plate 4, and then the two fixed clamping plates 4 are tightened with the fastening bolts 6 so that the two fixed clamping plates 4 are firmly clamped on the bollard 5. Finally, the steel wire rope 3 can be passed through the inner cylinder 9, the pulley 2 and connected to the test object 1 for testing. The tensile test tooling can be disassembled, transported, stored and reused, and is applicable to different ship types or different equipment on the same ship; during the test process, when the ship tilts horizontally and vertically and the position of the ship changes relative to the test object, the front pulley always remains perpendicular to the force direction of the test object through its own rotation, without the need for manual adjustment of the angle of the tooling and the state of the ship, reducing the labor intensity of the test personnel and improving the safety factor of the test personnel, solving the difficulties of testing under harsh environmental conditions and testing under the state of excessive horizontal and vertical inclination of the ship, meeting the test requirements under various states of the ship, and without the need to adjust the state of the ship.
