Abstract
The present invention, which discloses one kind, prevents diesel locomotive brake shoe partial wear device, and including pull rod, the pull rod is symmetrical two-part structure, and each section includes upper boom, lower beam and brace, and groove is formed among pull rod；Two upper booms of pull rod are fixed on the centre position of brake head by attachment device；The port of the lower beam sets the flange and groove of mutual cooperation respectively, also sets up through hole and pin hole；Through-hole groove and multigroup pin hole are set in fixed plate, and two lower beams of pull rod are by passing through the bolt of the through hole and being integrally fixed through the pin of pin hole；Anti- torsion bar is also set up, the anti-torsion bar is fixed on the upper boom, brace, lower beam of pull rod.It is an advantage of the invention that：Brake shoe partial wear phenomenon eliminates, and locomotive operation is good, with substantially prolonging the service life of brake shoe than before, while reduces locomotive inspection and repair and with cost, alleviates the labor intensity of worker, improve the integrated use rate of locomotive, eliminate traffic safety hidden danger.
Description
Technical field
The present invention relates to diesel locomotives, and being specifically one kind prevents brake shoe partial wear device.
Background technology
Clasp brake diesel locomotive is mainly engaged in shunting service, since rail track limits to, frequently falls to modulate and move, accelerate
The secondary abrasion of each leverage friction, increase the gap of each leverage, and these member structures also exist in design, assembling between design
Gap and assembly clearance will generate very big gap error when these gaps are reflected on brake shoe together, these gaps will brake
When make the brake force that left and right sides obtains uneven, along with brake rigging itself is there are one transverse momentum is stood, so as to generate lock
Watt friction phenomenon.
The braking drag link system of former vehicle design as shown in Fig. 2, since installation site is in the one side of both sides wheel brake head,
When checking cylinder acts on, two external force certainly will be generated on the brake shoe stress point of both sides, cause brake shoe partial wear in the course of time.
Wheel tread shape is made of wheel rim and circular conical surface two parts, as shown in figure 3, belonging to worn profile tread, it is played
Guiding role.Due to the influence of tread profile during locomotive brake, brake shoe will be subject to one, and outwards braking component, this component will make
Brake shoe partial wear.
Due to the presence of disadvantages mentioned above, brake shoe partial wear causes brake shoe cisco unity malfunction, the brake shoe one side after eccentric wear to limit
After will scrap monoblock brake shoe, cause spare part significant wastage, Master Cost and maintenance cost caused to sharply increase；After brake shoe partial wear
Accelerate the abrasion of locomotive carrying idler tread, shorten the service life of rim；Brake shoe partial wear weakens the brake force of locomotive, increases braking
Distance brings very big security risk to driving.
The content of the invention
In order to solve the above technical problems, the object of the present invention is to provide a kind of device for preventing brake shoe partial wear, particular techniques
Scheme is as follows：
One kind prevents diesel locomotive brake shoe partial wear device, and including pull rod, the pull rod is symmetrical two-part structure, each
Duan Jun includes upper boom, lower beam and brace, and groove is formed among pull rod；Two upper booms of pull rod are fixed on brake shoe by attachment device
The centre position of support；The port of the lower beam sets the flange and groove of mutual cooperation respectively, also sets up through hole and pin hole；Gu
Through-hole groove and multigroup pin hole be set on fixed board, and two lower beams of pull rod are by passing through the bolt of the through hole and through pin hole
Pin be integrally fixed；Anti- torsion bar is also set up, the anti-torsion bar is fixed on the upper boom, brace, lower beam of pull rod.
The attachment device is：The male cooperation of the end set groove of upper boom, the groove and brake head, pin pass through
The through hole set on groove；The through hole is multigroup.
It is an advantage of the invention that：Brake shoe partial wear phenomenon eliminates, and locomotive operation is good, with substantially prolonging brake shoe than before
Service life, while reduce locomotive inspection and repair and with cost, alleviate the labor intensity of worker, improve the synthesis of locomotive
With rate, traffic safety hidden danger is eliminated.
Description of the drawings
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is prior-art illustration；
Fig. 3 is wheel tread shape figure.
Specific embodiment
The present invention is illustrated below in conjunction with the accompanying drawings, as shown in Figure 1, the present invention includes pull rod 3, the pull rod 3 is symmetrical
Two-part structure, each section includes upper boom 31, lower beam 33 and brace 32, and groove is formed among pull rod, universal to avoid
Axis 2；Two upper booms 31 of pull rod are fixed on the centre position of brake head 1 by attachment device 4；The port difference of the lower beam 33
The flange 8 to cooperate and groove 9 are set, also set up through hole and pin hole；Through-hole groove and multigroup pin are set in fixed plate 11
Hole, two lower beams 33 of pull rod are by passing through the bolt 10 of the through hole and being integrally fixed through the pin 6 of pin hole；It is anti-
Only the turning of pull rod 3 occurs angle change and then influences the both ends length of pull rod 3；Also set up anti-torsion bar 7, the anti-torsion bar 7
It is fixed on by axis 12 on the upper boom 31, brace 32, lower beam 33 of pull rod, in this way, pull rod is formed stable triangle connection
Structure.
For ease of the length at adjustment pull rod both ends, the attachment device 4 is：The end set groove of upper boom 31, it is described recessed
The male cooperation of slot and brake head, pin 6 pass through the through hole 5 set on groove；The through hole 5 is multigroup.The connection structure can
By the length that pin is arranged on to different through hole adjusting yoke both ends；And lower beam and the connection structure in fixed plate, due to
There is provided multiple pin holes, the length at pull rod both ends can also be adjusted；Two regulating devices cooperate, convenient for easily combining
Into different length.
It, can be by each leverage in the brake rigging of clasp brake diesel locomotive in order to obtain superior technique effect
Nylon jacket changes steel bushing into.Rigidity, the intensity of casing when so not only can guarantee braking, but also the deformation of guide can be reduced, reduce each bar
Activity between system does not cause lever, brake shoe during braking to generate swing.
