Description
Technical field
The present invention relates to railway, highway freight field, be particularly useful for open type compartment with top cover.
Background technology
The open type compartment be meant have end wall, sidewall, floor and do not have roof, the boxcar that is open upwards mainly supplies to transport coal, ore, ore deposit and builds mass freight usefulness such as goods and materials, timber, steel, also can be used to transport the little mechanical equipment of weight.If behind overspread waterproof canvas on the goods that is loaded and transported or other awning things, the goods that can replace box car acknowledgement of consignment Keep away from rain to drench.Therefore the open type compartment has very big commonality, and quantity is maximum in lorry is formed, and the total open type compartment of railway is about 300,000 at present, accounts for more than 50% of lorry sum.If handling load can cause and get rusty, go bad etc. being drenched with rain, and loose goods can produce airborne dust in transportation, and environment is impacted; Common way is to adopt tarpaulin to hide, yet it is time-consuming, rainproof not thorough to hide tarpaulin; Cannot say for sure to manage; Be prone to lose, often handling load still receives damage by water, and bulk freight is owing to humidity has increased the unloading difficulty.Therefore, having occurred successively both at home and abroad is open type compartment design-calculated top cover specially, is the Chinese patent " railway transportation open type compartment special-purpose top cover " etc. of CN2441704 like publication number.But when existing top cover was installed in the open type compartment, the fixed form of top cover was loaded down with trivial details, and poor reliability is opened inconvenience, has limited the use of open type compartment to top cover, has restricted the performance of open type compartment benefit.
Summary of the invention
Technical matters to be solved by this invention provides the cap lock buckle device in a kind of open type compartment, make top cover can reliable connection on the open type compartment, open flexibly.
For solving the problems of the technologies described above, the cap lock buckle device in open type provided by the invention compartment is characterized in that, comprises pedestal, suspension hook seat, suspension hook, lock hook seat, latch hook, connecting rod; Said pedestal comprises riser, upper cover plate and base plate, and said upper cover plate and base plate are installed in the top and the bottom of riser respectively, and said base plate connects top cover edge, open type compartment; The hook end of said suspension hook is connected on the suspension hook seat up, and said suspension hook seat connects said riser, and can on the vertical direction between said upper cover plate and the base plate, slide by said relatively riser; Said lock hook seat is hinged on said pedestal bottom, and the hook end of said latch hook is connected on the lock hook seat down; Said suspension hook seat top and said lock hook seat flexibly connect through said connecting rod, and the connection end point of said connecting rod and said suspension hook seat, lock hook seat is positioned on said suspension hook seat, the lock hook seat side away from said riser respectively.
Further, said suspension hook seat bottom is a wedge shape, and the inclined-plane that matches with said lozenges is arranged on the said lock hook seat; When said lock hook seat inclined-plane cooperated with said lozenges closed contact, latching system was in tight lock state.
Mounting spring between said upper cover plate and suspension hook seat; Spring applies downward tension force to the suspension hook seat; Further strengthen the downward pressure of suspension hook seat, prevent in the vehicle operating process, make the reduction of suspension hook gravity because of jolting or move up lock hook seat; Make the top chord of hook-type latch hook disengaging car body, the phenomenon that meets accident and break off relations.
For increasing the alerting ability of open type carriage top cover lock buckle device at the attachment point of top cover, between said base plate and top cover, increase and adorned base, said base plate connects top cover edge, open type compartment through base; Said base is installed on the top cover edge, said open type compartment through general bolt, has elongate slot on the base, has screw on the base plate of pedestal, and general bolt passes said elongate slot and with screw base is connected with base plate.Like this, open type carriage top cover lock buckle device can move to location and installation behind the required horizontal position in the elongate slot on base.
Screw on the said base plate is a slotted hole, and the length direction of slotted hole is vertical with the length direction of elongate slot.Like this, open type carriage top cover lock buckle device can move to location and installation after the required lengthwise position at relative top cover edge in the base plate slotted hole.
Said lock hook seat comprises fixing device, and said latch hook is connected on the said lock hook seat through this fixing device.Like this, the upper-lower position of latch hook on fixing device is adjustable, is convenient to be applicable to the top chord of different size.
As a kind of optimal way; Said fixing device comprises square clip slot, bolt hole, fastening bolt; Said latch hook comprises coupler body and lead screw, and said lead screw is connected the coupler body top, and coupler body inserts in the square clip slot from the bottom to top; The lead screw head stretches out square clip slot and nut is installed, and said fastening bolt passes square clamping trough wall through bolt hole and connects said coupler body.Through the length that the lead screw head stretches out square clip slot, regulate the length of latch hook, to adapt to the top chord of different size.
In order to prevent or alleviate in lifting during top cover that the suspension hook seat is to the impulsive force of said pedestal upper cover plate, position-limited lever is installed on the said riser top on said suspension hook seat, is used to limit the hoisting position of suspension hook seat, bears the most suspension hook seat impulsive force that makes progress.
As preferably, said suspension hook seat top has the guiding slotted eye; Have axis hole on the said lock hook seat, the hinged said lock hook seat of an end of said connecting rod, the other end connects said guiding slotted eye.
Another is preferred, has the guiding slotted eye on the said lock hook seat; Said suspension hook seat top has axis hole, the hinged said suspension hook seat of an end of said connecting rod, and the other end connects said guiding slotted eye.
The occupation mode of open type carriage top cover lock buckle device of the present invention is: the open type carriage top covers to distribute installs several open type carriage top cover lock buckle devices; When top cover fell to being positioned on the roof, suspension hook to lower slider, drove lock hook seat through connecting rod and overturns downwards under the deadweight effect; The hook-type latch hook is hooked on the curb girder of car body; Thereby realize falling to covering automatic latch hook, make top cover firmly cover roof, prevent rainwater intrusion and goods dust pollution environment.When opening top cover, lifting appliance hooks said suspension hook, upwards lifting; At this moment, suspension hook upwards slides at pedestal under draw on the lifting appliance; Drive upwards upset of lock hook seat through connecting rod, the hook-type latch hook is broken away from from the top chord in compartment, thereby realize automatic unlocking.
The present invention is simple in structure, make top cover can reliable connection on the open type compartment, open flexibly, prevent effectively that rainwater from invading to cause goods damage, avoid goods dust pollution environment simultaneously.Therefore improved the usefulness of utilizing in open type compartment greatly, be worth greatly promoting the use of.
