Description
Technical field
The utility model belongs to multistage booster and uses point type separator technical field, is specifically related to a kind of composite explosion protection bolt box structure.
Background technology
The point type separators such as blasting bolt are selected in stage separation, are isolation technics the most frequently used in multistage booster flight course.The feature of point type separator work will have suitable bearing capacity when being not to be separated, and ensures the inter-stage coupling stiffness of carrier rocket, thus guarantees the safety of flight, when needs are separated, disconnect or unlocks, generally can discharge larger impulsive force.In carrier rocket flight process, the load of drawing of inter-stage is mainly born by point type separator, thus causes larger single-point concentrated force to the sub-level cabin body of rocket.Generally, point type separator connects by blasting bolt box.
Blasting bolt box is generally the square box shaped structure in 5 faces, inside bulkhead or outside there is no box wall, and lid is housed, for the demolition, installation of blasting bolt; Specific constructive form can with reference to (" researchs of typical blasting bolt bearing capacity " such as Hou Chuantao, " intensity and environment ", p32-p37,38 (4), 2011), Wu Yanhong etc. (" blast analogue of blasting bolt box and impact strength calculate ", p10-p15,34 (6), 2007).
Above-mentioned blasting bolt box is single box, and its load is delivered on the end frame of cabin body, covering, longitudinal girder by box body, dynamic changes process rule be X, Y, Z tri-the box in direction to unidirectional end frame, longitudinal girder transmission.As bolt box be only connected with arranged on left and right sides structure time, this kind of organization plan is selected comparatively general, and it is no problem to use.But when bolt box is connected with left and right, rear three directions, find through test, this kind of structure is concentrated at three direction point of intersection stress, distortion is difficult to coordinate, load cannot effectively be transmitted, and only by increase box body thickness, structure efficiency is very low.
Summary of the invention
The purpose of this utility model is to improve traditional blasting bolt box in the design efficiency with structure during multi-direction being connected, reaching load and effectively, evenly transmit, alleviate the object of construction weight.
To achieve these goals, technical scheme of the present invention is, a kind of composite explosion protection bolt box structure, comprises outer bolt box and inner bolt box; Wherein, outer bolt box comprises end frame, floor, outer bolt box backboard, outer bolt box side plate, upper plate and lower shoe; Floor is arranged on the outer middle side part of outer bolt box backboard, and outer bolt box backboard both sides at right angle setting is fixed with outer bolt box side plate; Floor, outer bolt box backboard and outer bolt box side plate upper end are connected with upper plate, and lower end is provided with lower shoe; Upper plate both sides stretch out and form end frame, and end frame is for being fitted on cabin body by box-packed for outer bolt; Upper plate center is provided with outer blasting bolt connecting hole; End frame, floor, outer bolt box backboard intersect at region of stress concentration on the downside of blasting bolt connecting hole outside; When outside blasting bolt connecting hole bearing large single-point load upwards, stress raisers, the load diffusion effect of region of stress concentration are undesirable; Inner bolt box comprises top board, inner bolt box backboard and two inner bolt box side plates, and inner bolt box backboard both sides at right angle setting fixes inner bolt box side plate; The top of inner bolt box backboard, inner bolt box side plate is provided with top board, and top board center arranges implode bolt connecting hole; Inner bolt box backboard, inner bolt box side plate, top board form dustpan shape structure, and backboard, inner bolt box side plate, top board have some through holes for arranging screw or rivet; Inner bolt box overall dimensions is with spatial match in the box of outer bolt box, namely top board outside height is mated with upper plate inside height, inner bolt box backboard bottom surface width mates with outer bolt box backboard inner surface width, and two inner bolt box side plate geomeries are with two outer bolt box side plate couplings.
Described outer bolt box backboard has outer bolt box backboard lightening hole.
Bolt box backboard lightening grooves over described outer bolt box backboard bottom.
Inner bolt box backboard lightening grooves is had in the middle part of described inner bolt box backboard.
Described inner bolt box side plate has inner bolt box side plate lightening grooves.
The beneficial effects of the utility model are, by the composite explosion protection bolt box structural change power pass through mechanism of large concentrfated load of outer bolt box and inner bolt box composition, under identical bearing capacity, weight reduces about 20%.
