Description

TECHNICAL FIELD

[0001] The application relates to a disk spring friction energy consumption self-resetting gate anti-collision structure and belongs to the technical field of ship lock gates of navigable structures. BACKGROUND

[0002] With the rapid development of water transportation, the number of ship locks has rapidly increased in recent years in China, and the normal opening and closing of the gates are necessary conditions for the safe operation of the ship locks. In order to better protect the ship lock gates and ensure the safety of the ships passing through the ship locks, anti-collision facilities are generally arranged on the gate bodies.

[0003] At present, the gates are basically of a space truss system, and the anti-collision system thereof is mostly in the form of a support rod system and an anti-collision panel. This form has almost no energy dissipation effect under the impact of the ships and is a rigid collision. With the acceleration of the large-scale development of the ships, the impact kinetic energy of the ships is increased, and the anti-collision system and the gate body are prone to deformation and damage under the impact of the ships. The vibration of the gate body is easy to cause the cracking of the welds, reduce the safety degree and service life of the gate body, and is not easy to replace or maintain, thereby affecting the normal navigation of the ship lock. On the other hand, the traditional anti-collision system has a large self-weight, causes the weight of the gate body to be unbalanced, and has an impact on the stable operation of the gate, the service life of the supporting operating parts and the like.

[0004] In recent years, a new type of buffer energy dissipation device has been widely applied in the industrial field. Therefore, in combination with the special requirements of the anti-collision system of the ship lock gate, a light, energy-dissipating and easy-to-replace anti-collision system of the ship lock gate is developed, which has high practical significance and good popularization and application value. SUMMARY

[0006] To achieve the above-mentioned purpose, the application adopts the following technical scheme:

[0007] The application first provides a friction energy dissipation self-resetting gate anti-collision unit, characterized by comprising an anti-collision plate, a self-resetting energy dissipation device and a buffer device; two connecting parts are arranged on the back surface of the anti-collision plate, and the two ends of the self-resetting energy dissipation device are fixed on one of the connecting parts; the buffer device is perpendicular to the plane of the anti-collision plate, one end of the buffer device is fixed on the middle part of the self-resetting energy dissipation device, and the other end of the buffer device is used for connecting the gate body.

[0008] The self-resetting energy dissipation device comprises a structure inner tube, a structure outer tube, an energy dissipation resetting device and a friction energy dissipation device; the two ends of the structure inner tube are connected with the two connecting parts of the anti-collision plate; the energy dissipation resetting device and the friction energy dissipation device are both arranged in the middle of the structure inner tube and the structure outer tube, and the energy dissipation resetting device is located between the two friction energy dissipation devices.

[0010] An inner plate reinforcing plate is arranged on the structural inner tube in the circumferential direction; the inner tube friction plate is welded with the inner plate reinforcing plate.

[0011] The energy dissipation reset device is composed of an elastic reset element and a baffle; the baffle is located on both sides of the elastic reset element, and the baffle is sleeved on the structural inner tube and can slide axially along the structural inner tube.

[0012] The elastic reset element is a disc spring.

[0013] The buffer support pipe rod comprises a pipe rod inner tube, a pipe rod outer tube, an end joint and a buffer reset device; the pipe rod inner tube and the end joint are arranged at one end of the pipe rod outer tube respectively; the buffer reset device comprises a buffer reset element and a buffer baffle, the buffer baffle is fixed in the pipe rod outer tube, one end of the buffer reset element is connected with the buffer baffle, and the other end of the buffer reset element is connected with the inner end of the pipe rod inner tube.

[0014] A hoop connecting device for connecting the gate body is arranged at one end of the buffer device for connecting the gate body.

[0015] The anti-collision plate is a honeycomb plate.

[0016] The application also provides a friction energy dissipation self-resetting gate anti-collision device, which is characterized by being connected by the friction energy dissipation self-resetting gate anti-collision units in the horizontal direction and the vertical direction.

[0017] The working mechanism of the gate anti-collision structure is that: the anti-collision plate serves as a first-level energy storage deceleration device, deforms first after being impacted, and consumes the impact energy generated by the impact; the self-resetting energy dissipation device serves as a second-level energy storage deceleration device, consumes the impact energy generated by the impact after being impacted, deforms at the same time as the structure deforms, and provides sufficient restoring force for the self-resetting of the structure after being impacted; the buffer support pipe rod serves as a third-level energy storage deceleration device, elastically deforms and consumes the impact energy generated by the impact after being impacted, deforms at the same time as the structure deforms, and provides sufficient restoring force for the self-resetting of the structure after being impacted.

[0022] The traditional gate anti-collision structure is mainly in the form of a support rod system and an anti-collision panel, and is basically rigidly connected, almost has no energy dissipation effect under impact, and is easy to be permanently deformed and damaged. The friction energy dissipation self-resetting gate anti-collision structure is simple in structure and clear in stress; at the same time, the aluminum alloy honeycomb plate, the self-resetting energy dissipation device and the buffer support pipe rod in the structure can simultaneously play the energy dissipation effect, have multiple energy dissipation and protection mechanisms, and have excellent energy dissipation performance.

[0023] The traditional gate anti-collision structure has a large self-weight, causes the door body to be overweight, and affects the stable operation of the gate, the service life of the supporting running parts and the like. The friction energy dissipation self-resetting gate anti-collision structure adopts light materials and has a simple structure, and thus has a light self-weight, is beneficial to prolonging the service life of the gate, and has good comprehensive economic benefits.

[0024] The disc spring is used as the self-resetting element, and different specifications of the disc spring can meet different deformation and restoring force requirements, so that the problems of insufficient limited elastic deformation capacity and high cost of the existing self-resetting materials are overcome.
