Detailed description of the invention
As Figure 1-3, a kind of catch gear shielding trailer described in the embodiment of the present invention, comprise trailer body 1 and the support body 2 being positioned at trailer body 1 front, described support body 2 inner bottom part is provided with the connecting panel 4 coordinated with trailer driving chain 3, described connecting panel 4 is rotatably connected to crank connecting link 5, described crank connecting link 5 top is rotationally connected the bottom of lock core 6, the profile on described lock core 6 top matches with the profile of trailer body 1 front end latch hook 7, the top of described lock core 6 is provided with lock core hole 8, lock core marble 9 is provided with in described lock core hole 8, the front end of described lock core marble 9 is squeezed push rod 10, the rear of described lock core 6 is provided with push rod 11, described push rod 11 is arranged on trailer body 1, described push rod 11, lock core marble 9 and push rod 10 are a straight line when trailer state of kinematic motion, described support body 2 top is fixedly connected with mounting box 12, and the middle and upper part of described lock core 6 is flexibly connected with mounting box 12, and described push rod 10 is arranged in mounting box 12 anterior, the top of described connecting panel 4 and the bottom of lock core 6 are equipped with turning cylinder, and described turning cylinder matches with the axis hole at crank connecting link 5 two ends, described lock core 6 is provided with brake component 61, brute spring 62 and attaching parts 63 from top to bottom successively, the top of attaching parts 63 is placed on and brake component 61 is connected by screw 64 with attaching parts 63 center in the bottom of brake component 61, the top overcoat of attaching parts 63 has brute spring 62, and described brake component 61 and attaching parts 63 are provided with brake clearance in vertical direction, described push rod 10 overcoat has pellet sleeve 13, and described push rod 10 is stepped shaft structure and one end overcoat of small diameter has spring 14, and the two ends of described spring 14 are squeezed in the larger-diameter one end of push rod 10 and pellet sleeve 13 respectively.Described push rod 11 is all arranged on fixed body device 15 with latch hook 7, and described fixed body device 15 is connected with trailer body 1 by pad.The thickness of described pad comprises 1mm, 2mm and 3mm tri-kinds.The front portion of described trailer body 1 is provided with two shock absorbers 17 side by side, and described shock absorber 17 inside is provided with recoil spring 18.The both sides of described support body 2 are equipped with safety pin 19, and the contact site of described connecting panel 4 two ends and safety pin 19 is trapezoidal, and trapezoidal top end face is provided with safe pin-and-hole 16
As shown in Figure 4, be trailer body 1 free state, between push rod 11 and lock core marble 9, have certain distance, lock core 6 pins by lock core marble 9 together with push rod 10, whole catch gear can not move, and connecting panel 4 contacts with driving chain 3 brakeless, and crank connecting link 5 can not rotate.Planker is also in the lock state.Trailer now can drag with drag chain.Left and right can be freely automatic.When trailer starts to brake, the deceleration acceleration/accel of support body 2 is greater than the deceleration acceleration/accel of trailer body 1, trailer body 1 starts to support body 2 close, push rod 11 is driven to start to move to lock core marble 9, then push rod 11 touches lock core marble 9 and continues extruding lock core marble 9, until lock core marble 9 is clamp-oned in lock core 6 by push rod 11 completely, now push rod 10 is extruded lock core 6 by the other end of lock core marble 9 completely, only have lock core marble 9 in the lock core hole 8 of lock core 6, lock core 6 can up-and-down movement.
As shown in Figure 5, be ultimate limit state when trailer body 1 travels forward.Lock core marble 9 is compressed into lock core 6 body by push rod 11.Now lock core 6 is in up and down free state.Now connecting panel 4 continues to left movement under the drive of drag chain.Drive crank connecting link 5 to rotate, pushing lock cylinder 6 inserts latch hook 7.The ultimate limit state that last trailer moves to.Connecting panel 4 continues arrival ultimate limit state of moving left under the drive of drag chain.Drive crank connecting link 5 to rotate, pushing lock cylinder 6 inserts latch hook 7 and crosses first dead center.Because lock core 6 is the fabricate blocks with spring, compressible 10-15mm.Therefore cross after top dead center, lock core 6 still gives latch hook 7 enough locking pressure.Now driving chain 3 stop motion, braking procedure terminates, and whole system is in stabilized conditions.
Meanwhile, to be on the safe side, two safety pins 19 are installed additional in support body 2 both sides.When connecting panel 4 is to left movement, inclined-plane, connecting panel 4 side jack-up safety pin 19; When connecting panel 4 move left reach the limit of time, safety pin 19 just falls and inserts connecting panel 4 bottom outlet.Find through overtesting, when the gradient of plunger is greater than Mohs No. 6 taperings 2 degree 59 points 12 seconds and is less than 5 degree, safety pin 19 can conveniently be extracted again by safety locking.
The present invention is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but any change is done in its shape or structure; every have identical with the application or akin technical scheme, all drops within protection scope of the present invention.
