specific Embodiment approach 1

[0006] Specific implementation mode one: (see figure 1 , Figure 4 ) This embodiment consists of a fixed hinge bracket 1, a fixed rod 2, a bearing rod 3, a bearing rod plug 3-1, a drive rod 4, a limit reed 5, a translational hinge bracket 6, a movable rod 7, and a sliding sleeve 8 It is composed of the linear guide rail 9, one end of the fixed rod 2 is fixedly connected with the lower end of the linear guide rail 9, the space between the fixed rod 2 and the linear guide rail 9 is set at right angles, the fixed hinge bracket 1 is fixed on the other end of the fixed rod 2, and the sliding sleeve 8 is set on the linear guide rail 9, one end of the movable rod 7 is fixedly connected with the sliding sleeve 8, the movable rod 7 and the sliding sleeve 8 are arranged at right angles, and the translation hinge bracket 6 is fixed on the other end of the movable rod 7, The limit reed 5 is fixed on the movable rod 7 on the outside of the translation hinge bracket 6, the lower end of the...

specific Embodiment approach 2

[0007] Specific implementation mode two: (see figure 2 , image 3 ) The bottom end surface 5-3 of the limiting reed 5 of the present embodiment is arc-shaped, and the bottom end surface 5-3 of the limiting reed 5 has a through hole 5-1, and the opening end of the limiting reed 5 is " X" shaped socket 5-2. Others are the same as in the first embodiment. This embodiment is the basic configuration of the limit spring 5 installed on the translation hinge bracket 6 . The bearing rod plug 3-1 on the bearing rod 3 is inserted into the reed from the opening of the limit reed 5. The insertion process causes the limit reed 5 to deform and prevent the bearing rod 3 from moving, so the translational hinge bracket 6 needs to have a relatively large force, so as to ensure that the moment generated by the force acting on the bearing rod 3 through the drive rod 4 can overcome the deformation of the limit reed 5 and enter the limit reed 5. Conversely, if the bearing rod 3 is to be disenga...

specific Embodiment approach 3

[0008] Embodiment 3: The material of the limiting reed 5 in this embodiment is 60CrMnA, and the hardness is 45-50HRC. Others are the same as in the second embodiment.

Abstract

A force strengthening mechanism in vertical direction aims to solve the problem of lower axial rigidity of the entire arm when the root section of the prior large space crane arm is fastened. A rightangle arrangement is provided between a positioning rod and a linear guide rail, a slide sleeve is arranged on the linear guide rail, a movable rod is fixedly connected with the slide sleeve at one end, a force bearing rod is hinged with a fixed hinge support at the lower end, a right angle arrangement is provided between the movable rod and the slide sleeve, a drive rod is hinged with a flat hinge support at one end and is hinged with the middle section of the force bearing rod at the other end, and a force bearing rod plug on the force bearing rod is matched with a position-limit spring. Theentire force strengthening mechanism has compact design and light weight, and can achieve force strengthening and position limiting in vertical direction. The force strengthening mechanism has forcestrengthening effect only at specific positions and has low energy consumption because friction resistance is present between kinematic pair in other movement process. The force strengthening mechanism can also achieve repeated force strengthening function, significant force strengthening effect, and simple structure.

Description

technical field [0001] The invention relates to a booster mechanism. Background technique [0002] Although the problem of accurate locking in the loading barrel of the large-scale space extension arm after it is fully deployed has been solved, there is still the problem of low axial stiffness of the entire arm after the root of the extension arm is locked. This problem has not been solved so far. Method. Contents of the invention [0003] The purpose of the present invention is to provide a vertical force boosting mechanism to solve the problem of low axial stiffness of the entire arm after the root of the existing large space extension arm is locked. The present invention is composed of a fixed hinge bracket, a fixed rod, a load-bearing rod, a load-bearing rod plug, a drive rod, a limit reed, a translational hinge bracket, a movable rod, a sliding sleeve and a linear guide rail. One end of the fixed rod and the linear guide rail The lower end is fixedly connected, the ...
