Description

Technical Field

[0001] The utility model relates to the technical field of ship equipment, in particular to a vibration reduction and sway reduction device for a plunger type steering gear. Background Art

[0002] The plunger-type steering gear is a type of steering gear. Together with the ship's propulsion power unit, it is used to control the ship's navigation direction and ensure that the ship can quickly and reliably turn the rudder blade to and maintain the specified rudder angle as required, so that the ship can sail on a given route. The plunger-type steering gear is a product with a high degree of mechanical, electrical and hydraulic integration, consisting of a steering gear fastening, a hydraulic system, and an electronic control system. The steering mechanism consists of a plunger, a plunger pin, a cylinder, a tiller, a slider and other components; the hydraulic system consists of a closed plunger pump, a valve group, a motor, an oil tank (including a reserve oil tank), etc.; the electronic control system consists of an electrical starter box, an alarm junction box, an alarm board, etc. The plunger moves back and forth in a straight line under the action of oil pressure, thereby driving the rudder to swing. The plunger limits the limit stroke to achieve the limit angle of rotation of the steering gear.

[0003] Application No. 202220715150.0 relates to a vibration reduction and sway reduction device for a plunger-type steering gear, and belongs to the technical field of ship equipment. It includes a plunger-type steering gear, which includes a steering gear body and a rudder angle indicator, and a base is provided at the bottom of the steering gear body; the base is a split structure as a whole, including a first base, a transverse tie rod and a second base, and the first base and the second base are symmetrically arranged on both sides of the transverse tie rod; the transverse tie rod is arranged as a boss-type arch bridge structure as a whole; a through hole for passing the rudder angle indicator is provided at the top of the transverse tie rod; an opening for operation and maintenance personnel to enter is provided at the bottom of the transverse tie rod. The transverse tie rod added by the utility model enables the rudder angle indicator to pass through without affecting the operation of the steering gear indicator connecting rod.

[0004] Although an opening is provided at the bottom of the transverse tie rod for operation and maintenance personnel to enter, which facilitates maintenance by operation and maintenance personnel, after the plunger-type servo is connected to the first base and the second base, the vibration generated during operation of the plunger-type servo will cause the connection between the first base and the second base to loosen, thereby causing the plunger-type servo to separate from the first base, increasing the difficulty of maintenance. Therefore, a vibration reduction and sway reduction device for the plunger-type servo that can buffer vibration is needed. Summary of the invention

[0005] In order to solve the above technical problems, the utility model provides a vibration reduction and sway reduction device for a plunger-type steering gear.

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment. Example

[0026] Please combine Figure 1-4 , a vibration reduction and sway reduction device for a plunger-type steering gear of this embodiment comprises a main body mechanism 1, a steering gear mechanism 2 and a buffer mechanism 3, wherein the steering gear mechanism 2 is located at the top of the main body mechanism 1, and the buffer mechanism 3 is located inside the steering gear mechanism 2;

[0027] The main mechanism 1 includes a limit block 101, the bottom of the limit block 101 is fixedly connected to a fixed base 102, the inner wall of the limit block 101 is fixedly connected to a mounting plate 103, the bottom of the fixed base 102 is fixedly connected to a base spring 104, the interior of the fixed base 102 is fixedly connected to a connecting spring 105, and the top of the fixed base 102 is provided with a mounting position 106, the number of the limit blocks 101 is provided with two, and the two limit blocks 101 are symmetrically distributed with the fixed base 102 as the center, the number of the mounting plates 103 is provided with two, and the two mounting plates 103 are symmetrically distributed with the fixed base 102 as the center, the number of the base springs 104 is provided with four, and the four base springs 104 are equidistantly distributed with the mounting plate 103 as the center, the number of the connecting springs 105 is provided with two, and the two connecting springs 105 are symmetrically distributed with the mounting plate 103 as the center, the mounting position 106 and the limit block 101 limit the displacement of the plunger 201, and then the vibration of the motor is reduced by the spring.

[0028] The steering gear mechanism 2 includes a plunger 201, which is rotatably connected to the inside of the mounting position 106. A hydraulic rod 202 is inserted at the bottom of the plunger 201, and a power pump station 203 is fixedly connected to the top of the hydraulic rod 202. The end of the hydraulic rod 202 away from the power pump station 203 is fixedly connected to a motor plate 204, and a mounting block 205 is fixedly connected to the bottom of the hydraulic rod 202. There are two hydraulic rods 202, which are symmetrically distributed with the plunger 201 as the center. There are four groups of mounting blocks 205, which are equidistantly distributed with the plunger 201 as the center. The mounting blocks 205 mount the hydraulic rod 301 on the mounting plate 205.

[0029] The buffer mechanism 3 includes a buffer rod 301, which is fixedly connected to the inner wall of the limit block 101. The buffer rod 301 is internally slidably connected with a buffer head 302. There are two buffer rods 301, which are symmetrically distributed around the plunger 201. The buffer head 302 inside the buffer rod 301 reduces the impact when the plunger 201 rotates.

[0030] The implementation principle of a vibration reduction and sway reduction device for a plunger-type steering gear in the embodiment of the present application is as follows: during the installation process, the fixed base 102 is first installed, and then the steering gear mechanism 2 is installed with the mounting plate 103 through the mounting block 205. During installation, the base of the plunger 201 is installed in the mounting position 106. After the installation is completed, the vibration generated by the steering gear is transmitted to the cabinet base spring 104 through the mounting plate 103, and the force is unloaded through the base spring 104. The vibration generated when the plunger 201 is selected is buffered by the connecting spring 105, which greatly improves the shock reduction ability of the vibration reduction and sway reduction device of the plunger 201 type steering gear. When the plunger 201 rotates, the buffer head 302 contacts the plunger 201, and the vibration of the plunger 201 is reduced by the hydraulic pressure in the buffer rod 301, which greatly improves the sway amplitude of the vibration reduction and sway reduction device of the plunger 201 type steering gear.

Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
