Embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
The basic thought of the present invention is：A kind of rotating locking apparatus C, including the limiting component set on tail-gate frame are provided
With the second engaging part set in the first engaging part and tail-gate frame that are set on corresponding tail-gate, limiting component can phase
Moved for first engaging part and the second engaging part and cause itself and first engaging part and the second holding section
Part is in locking or loosens two states, so as to avoid tail-gate from opening by mistake, its simple in construction, significant effect.
As shown in Fig. 1 to 5, it is shown that a preferred embodiment of the invention, a kind of rotating locking apparatus C, for dumper
Tail-gate is locked, including：The first engaging part 10 being arranged on self-unloading tailstock door and the tail-gate for being arranged on body of tipper carriage rear portion
The engaging part 30 of limiting component 20 and second of rotatable flexible on frame.The engaging part of first engaging part 10 and second
30 and the position correspondence of limiting component 20, make limiting component 20 can be by rotary extension and first engaging part 10 and second
Engaging part 30 is in locking state or relaxation state.
In this embodiment, due to being provided with the first engaging part 10 on self-unloading tailstock door, and in self-unloading tailstock door
The second engaging part 30 is provided with frame, and the position of the first engaging part 10 and the second engaging part 30 is corresponded on tail-gate frame
Limiting component 20 is set, limiting component 20 can be made to be in after rotary extension with the first engaging part 10 and the second engaging part 30
Lock and loosen two states.Specifically, when needing locking door, rotary extension limiting component 20 to itself and the first engaging part
10 and second engaging part 30 be bonded, three is in locking state, now the limiting component 20 will limit tail-gate motion, keep away
Exempt from it to open by mistake；When needing to open door, rotary extension limiting component 20 to itself and the first engaging part 10 and the second holding section
Part 30 staggers a certain distance, three is in relaxation state, now the limiting component 20 will can no longer limit the motion of door, energy
Easily open tail-gate.Rotating locking apparatus C can pass through the first engaging part 10 and the second engaging part 30 and limiting component 20
Effectively engaging locking, significant effect, and it is simple in construction, manufacturing cost is cheap.
Specifically, after the limiting component 20 can be set directly at body of tipper carriage by fixtures such as welding or bolt and nuts
On the tail-gate frame in portion, and the second engaging part 30 again may be by the fixtures such as welding or bolt and nut and be set directly at certainly
Unload on the tail-gate frame at compartment rear portion.Or as in Figure 2-4, rotating locking apparatus C is also included mounting seat 40, make limiting section
The engaging part 30 of part 20 and second is arranged on tail-gate frame by the mounting seat 40.In the preferred embodiment, limiting component
20 and second engaging part 30 by the installation settings of mounting seat 40, can further improve the engaging part 30 of limiting component 20 and second
Smoothness and steadiness, so as to improve the locking journey of the engaging part 10 of limiting component 20 and first and the second engaging part 30
Degree, reaches more preferable locking effect.
Specifically, limiting component 20 can be any rotary extension after can be with the first engaging part 10 and the second engaging part 30
Mechanical structure in locking state or relaxation state, such as by the bar that can be manually rotated with it is fixed or movable be arranged on it is convex on bar
Mechanical structure that block is formed etc..
Preferably, as shown in figure 3, limiting component 20 includes the drive mechanism of rotatable flexible, the cylinder with drive mechanism 21
The cylinder rod 22 that the connection of cylinder 21 is set, and the limited block 23 being fixedly installed in cylinder rod 22.
In this embodiment, give the concrete structure of limiting component 20, its by the drive mechanism of rotatable flexible, with
After the cylinder barrel 21 of drive mechanism connects the cylinder rod 22 set, and the limited block 23 being fixedly installed in cylinder rod 22 realizes rotary extension
Lock or loosen the process of the first engaging part 10 and the second engaging part 30.Detailed, need to lock during material transportation
During tight door, drive mechanism is set to drive connected cylinder rod 22 to rotate, to drive the both ends of limited block 23 to move to first respectively
The surface of the engaging part 30 of engaging part 10 and second, then make drive mechanism drive the cylinder rod 22 being connected with its cylinder barrel 21 to contract
It is short, make the both ends of limited block 23 slowly close to the first engaging part 10 and the second engaging part 30, until the both ends of limited block 23
It is bonded respectively with the first engaging part 10 and the second engaging part 30, or without above-mentioned rotation and shortens two stages, directly
Connecing makes drive mechanism drive connected cylinder rod 22 to be moved with the spiral way of rotary extension, until the both ends point of limited block 23
Be not bonded with the first engaging part 10 and the second engaging part 30, make the first engaging part 10 and the second engaging part 30 with it is spacing
Block 23 is in locking state, and now the limited block 23 will limit the motion of tail-gate, it is ensured that and in transportation, material will not be revealed,
It tail-gate is opened by mistake due to jolting, security incident occur.Arrive at need open door when, drive mechanism can
On the basis of above-mentioned locking state, first the cylinder rod 22 being connected with its cylinder barrel 21 is driven to extend, to drive the both ends of limited block 23 slow
Slow remote first engaging part 10 and the second engaging part 30, make the first engaging part 10 and the second engaging moving a certain distance
