Problems solved by technology
[0002] In the field of mechanical traction, when multiple traction systems exert traction on the same object, the traction is often uneven due to the asynchrony between the traction systems. Damage to a traction system due to failure to synchronize without sharing traction
For the sake of safety, designers often design all traction systems according to the most dangerous limit conditions, resulting in waste of cost, and at the same time not completely solving the problem

Embodiment Construction
[0007] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:
[0008] As shown in Figure 1, when the weight 1 is dragged by two traction systems, two traction rods 4A and 4B act on the weight 1, and the two traction rods 4 are respectively connected to the pistons 2A and 2B, and the pistons 2A and 2B They are installed in the oil cylinders 5A and 5B respectively, and the oil cylinders 5A and 5B are respectively communicated with the same high pressure vessel 6 through the oil pipes 3A and 3B. The high-pressure container 6, the oil cylinders 5A, 5B, and the oil pipes 3A, 3B are filled with the same liquid in communication.
[0009] When the traction rods 4A, 4B pull the pistons 2A, 2B, due to the pressure transmission of the liquid, the pressure in the oil cylinders 5A, 5B, the oil pipes 3A, 3B, and the high-pressure container 6 are uniform, that is, each traction rod 4A The traction shared by 4B is equal. In this...

The present invention provides a conjugate traction equipment. Said equipment is composed of a high pressure container and several oil cylinders, pistons and traction pulling bars. Every traction pulling bar is connected with a piston mounted in an oil cylinder, on every oil cylinder an oil tube is set, and is connected with same high-pressure container. In the high-pressure container, oil cylinder and oil tube an identical liquor can be injected respectively, said high-pressure container is communicated with every oil cylinder and every oil tube, so that when the piston is pulled by traction pulling bar, the above-mentioned liquor has pressure-transferring action, therefore the pressures in the high-pressure container and every oil cylinder and oil tube are identical, and the traction forces of all the pulling bars also are identical.
Description
Technical field [0001] The invention relates to the field of mechanical traction. technical background [0002] In the field of mechanical traction, when multiple traction systems exert traction on the same object, the traction force is often uneven due to the lack of synchronization between the traction systems. It often happens that when a certain traction system bears a traction force exceeding the limit value, other traction systems Due to the inability to synchronize and not share the traction, a certain traction system is damaged. For the sake of safety, designers often design all traction systems in accordance with the most dangerous extreme conditions, resulting in cost waste, and at the same time, they may not completely solve the problem. Summary of the invention [0003] The object of the present invention is to provide a conjugate traction device, when multiple traction systems exert traction on the same object, to ensure that all traction systems bear the same tract...
