Description
Technical field
The utility model relates to a kind of car, relates in particular to a kind of novel semi-trailer.
Background technology
Usually the suspension vehicle frame of antenna superimposed trailer needn't separate with equipment platform, and in gas circuit control, do not adopt the integrated design thinking, be on the gas circuit air receiver, relay valve etc. with hang vehicle frame, compressed air brake cylinder is not fused to separate unit, when the suspension vehicle frame has demand to separate with equipment platform, need loading line and brake piping between 4 compressed air brake cylinders of dismounting and the air receiver relay valve, personnel operation is simple and direct inadequately.Adopt " die and stop " because of the gas circuit control of safe superimposed trailer, promptly just be in braking mode as long as tractor truck and superimposed trailer break away from the tire of rear overhang trailer frame.When hanging vehicle frame, needs are in the brake off state, dual mode is arranged at present: a kind of is that the adjusting bolt that unscrews in the automatic compensation arm just can make the tire brake off, need screw when need recover braking state and regulate bolt and then 1/4 circle that circles round, this operation is strongly professional.This measures bad grasp " 1/4 circle circles round ", regulates the performance of parking brake that can influence superimposed trailer not in place; Another kind of mode is to adopt standby bolt, and the compressed air brake cylinder inner push-rod that will be in the brake off state makes it be in the brake off state with standby bolted connection restriction push rod retraction.Though this operating mode is professional not strong, operate very inconveniently, personnel need lie prone and could operate under vehicle bridge.
So, in order to reduce the use of accessory equipment instrument, improve personnel operation, raising work for satisfying the train transportation request of large-scale antenna superimposed trailer.
The utility model content
Technical matters to be solved:
Provide a kind of making to hang moving and separating with docking operation simple and directly, safe and reliable with equipment platform of vehicle frame at above not enough the utility model, and can satisfy the novel semi-trailer of the train transportation request of large-scale antenna superimposed trailer.
Technical scheme:
A kind of novel semi-trailer comprises tractor truck, hangs vehicle frame, equipment platform and air-path control system, and hanging vehicle frame and equipment platform is two separate units, hangs vehicle frame and equipment platform by revolving phase-locked the connection; Described air-path control system comprises compressed air brake cylinder, rapid release valve, emergency relay valve, air receiver, switch valve, quick coupling, brake piping, loading line, T-pipe joint, hand brake; Compressed air brake cylinder links to each other with rapid release valve, emergency relay valve, rapid release valve links to each other with air receiver with T-pipe joint by hand brake successively, emergency relay valve links to each other with air receiver, brake piping, loading line, be provided with switch valve between air receiver and the brake piping, switch valve links to each other with air receiver by T-pipe joint, air receiver is arranged on and hangs on the vehicle frame, and brake piping between brake piping between tractor truck and the equipment platform and loading line and suspension vehicle frame and the equipment platform and loading line are respectively arranged with 1 quick coupling.
Beneficial effect:
The antenna superimposed trailer hangs the integrated design that vehicle frame separates and the brake gas circuit is controlled can satisfy the train transportation request, improves personnel's operating environment greatly.Be mainly reflected in: because of on the structure by revolve lock connect make rear overhang trailer frame and equipment platform butt joint with separate simple and directly, and only need 2 quick couplings of plug (appendix and brake pipe) to get final product on the gas circuit; After the separation, only need open a valve at releasing suspension vehicle frame brake operating and can realize.
Description of drawings
Fig. 1 is the utility model equipment platform structural representation;
Fig. 2 is that the utility model hangs the body frame structure for automotive scheme drawing;
Fig. 3 is the utility model air-path control system figure.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
As shown in Figure 1 to Figure 3, a kind of novel semi-trailer, comprise tractor truck 8, hang vehicle frame 14, equipment platform 10 and air-path control system, hanging vehicle frame 14 and equipment platform 10 is two separate units, two railway transportation unit have been separated into, hang vehicle frame 14 and be connected separation and simple to operation by revolving lock 15 scooping out with equipment platform 10.
The gas circuit control system of novel semi-trailer is included as the dual line braking control system, comprises loading line 9 and brake piping 7.Suspension vehicle frame 14 is with equipment platform 10 butt joints and separate only 2 quick couplings 6 of need plug.
Described air-path control system comprises compressed air brake cylinder 1, rapid release valve 2, emergency relay valve 3, air receiver 4, switch valve 5, quick coupling 6, brake piping 7, loading line 9, T-pipe joint 11, hand brake 12; Compressed air brake cylinder 1 and rapid release valve 2, emergency relay valve 3 links to each other, rapid release valve 2 links to each other with air receiver 4 with T-pipe joint 11 by hand brake 12 successively, emergency relay valve 3 and air receiver 4, brake piping 7, loading line 9 links to each other, be provided with switch valve 5 between air receiver 4 and the brake piping 7, switch valve 5 links to each other with air receiver 4 by T-pipe joint 11, air receiver 4 is arranged on and hangs on the vehicle frame 14, and brake piping 7 between tractor truck 8 and the equipment platform 10 and loading line 9 and the brake piping 7 and the loading line 9 that hang between vehicle frame 14 and the equipment platform 10 are respectively arranged with 1 quick coupling 6.
The effect that emergency relay valve 3 and rapid release valve 2 are installed between compressed air brake cylinder 1 and the air receiver 4 is to shorten brake response time, plays the function that " filling soon " " puts " soon.Increase a switch valve 5 between air receiver 4 and the brake piping 7 and realize after tractor truck breaks away from, removing the braking of hanging vehicle frame 14, promptly open switch valve 5 and make air receiver 4 open the path brake off of air receiver 4 compressed air brake cylinders 1 with control emergency relay valve 3 toward brake piping 7 air feed.
Though the utility model with preferred embodiment openly as above; but they are not to be used for limiting the utility model; anyly be familiar with this skill person; in the spirit and scope that do not break away from the utility model; can do various variations or retouching from working as, what therefore protection domain of the present utility model should be defined with the application's claim protection domain is as the criterion.
