Description
Technical field
The utility model relates to rail transit locomotive buffer unit technical field.
Background technology
Coupler and draft gear is for making vehicle and vehicle, locomotive or the motor-car extension that interconnects mutually, and transmitting tractive power, brake force also relaxes the vehicle part of longitudinal impact force.It is by hitch, buffer, hook tail frame, and slave plates etc. form a whole, and are installed in the draw beam of body frame structure end.For the interchangeability that ensures that coupling of vehicles is safe and reliable and coupler and draft gear is installed, the relevant code regulation of China railways rolling stock: after coupler draft gear entrucking, the horizontal center line of its coupler knuckle for car coupler is the height under complete vehicle curb condition apart from rail surface, passenger vehicle is 880mm(permission+10mm,-5mm error), lorry is 880mm(± 10mm).The hitch horizontal center line maximum height difference of two adjacent vehicles must not be greater than 75mm.
Coupler draft gear is the structure member of the power that often withstands shocks, and generally comprises friction-type buffer and rubber bumper, and wherein, friction-type buffer is that vibration is converted into frictional heat energy; Rubber bumper is to play to relax by the friction in rubber molecule and strain to impact and catabiotic effect.Buffer is consumable accessory, in order to ensure that buffer reliably, work stably, requires to carry out in strict accordance with package technique in maintenance, because annual locomotive coupler maintenance amount is large, for the buffer of wearing and tearing, needs to decompose, dismantle and re-assembly.The elastic force and the slave plate that are dependence itself due to coupler draft gear tightly compress in the mount pad that is contained in car body buffer, must be by external force when dismounting, and dismounting is wasted time and energy, and affects repair schedule.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of portable hitch buffer dismounting tool, simple in structure, make easily, length is adjustable, easy to carry, use this instrument can fast assembling-disassembling coupler draft gear, greatly reduce labour intensity, improve dismounting efficiency.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of portable hitch buffer dismounting tool, comprise screw rod, the lower end of described screw rod is bolted with and the gripper shoe that can be supported in tailstock frame end face, also comprise the screwed connecting rod in two ends, the lower end of described connecting rod and the upper end of screw rod are spirally connected by screwed adapter sleeve, are also provided with in the upper end of connecting rod the fastener head being spirally connected with connecting rod.
Described connecting rod is more than one.
The free end of described screw rod is plane.
On described fastener head, be installed with handle.
The beneficial effect that adopts technique scheme to produce is: the utility model is split-type structure, between connecting rod and screw rod, connects by adapter sleeve screw threads for fastening, can take apart, is easy to carry, easy to use; It screws head and is provided with internal thread, can directly tighten and coordinate with screw rod, while therefore use, can remove as required connecting rod, shortens length, adapts to the needs of different spaces and operation occasion.This tool construction is simple, makes easily, uses this instrument can fast assembling-disassembling coupler draft gear, reduces labour intensity, improves dismounting efficiency, with respect to a large amount of coupler draft gear maintenance maintenance works, has greatly shortened the maintenance maintenance activity time.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model blast structural representation;
Fig. 3 is the structural representation of the utility model embodiment;
In figure: 1, handle; 2, screw head; 3, connecting rod; 4, adapter sleeve; 5, screw rod; 6, gripper shoe; 7, tailstock frame; 8, cotter hole; 9, front slave plate; 10, buffer.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Due to the needs of repair and maintenance, in the time locomotive coupler buffer being carried out to disassembly and assembly replacing, first need coupler yoke key to take out, hitch is pulled down, but because coupler draft gear elastic force is larger, the buffer after pulling down becomes full extension state, install more loaded down with trivial details.This instrument can make simple installation, time saving and energy saving.Below in conjunction with specific embodiment, this instrument is illustrated.
Embodiment 1
Referring to Fig. 1, Fig. 2, the utility model comprises the screwed connecting rod 3 of screw rod 5 and two ends, the upper end of the lower end of described connecting rod 3 and screw rod 5 is spirally connected by screwed adapter sleeve 4, be bolted with in the lower end of described screw rod 5 and the gripper shoe 6 that can be supported in tailstock frame 7 end faces, gripper shoe 6 is strip, and its two ends are placed in the cotter hole 8 of tailstock frame 7, and be supported on the end face of tailstock frame 7, the lower end of described screw rod 5 is plane, can contact with 9 of front slave plates.The upper end of connecting rod 3 is also provided with the fastener head 2 being spirally connected with connecting rod 3, on described fastener head 2, is installed with handle 1.
Referring to Fig. 3, when concrete use, first coupler yoke key is taken out, hitch is separated with front slave plate 9, take out hitch, gripper shoe 6 is placed in the cotter hole 8 of hook tail frame, and be positioned at front slave plate 9 before, now, gripper shoe 6 is limited in cotter hole 8, and be supported on the frame of hook tail frame, screw rod 5 and connecting rod 3 use adapter sleeves 4 are connected tight, and fastener head is screwed on connecting rod 3, insert handle 1, then screw rod 5 is screwed in to gripper shoe 6, turning handle 1, the end plane of screw rod 5 contacts with front slave plate 9, continue to screw, gripper shoe 6 produces outbreak firmly with hook tail frame, front slave plate 9 compression buffers 10, can make buffer 10 be installed in the tailstock frame 7 of car body.
While use, can be connecting rod 3, screw rod 5, screw 2, handle 1 and gripper shoe 6 take apart one by one, be convenient for carrying.
Embodiment 2
The difference of the present embodiment and embodiment 1 is: with screwing 2 directly and screw rod 5 is spirally connected.Can adapt to the limited place of space situations.
Embodiment 3
The difference of the present embodiment and above-described embodiment is: adopt more than two or two connecting rods to be spirally connected between two with adapter sleeve 4, then be spirally connected with screw rod, lengthen the body of rod, adapt to different needs.
This tool construction is simple, makes easily, uses flexibly, easy to carry, use this instrument can fast assembling-disassembling coupler draft gear, reduce labour intensity, improve dismounting efficiency, for a large amount of coupler draft gear maintenance maintenance works, can significantly save the maintenance maintenance activity time.
