Description

One kind prevents diesel locomotive brake shoe partial wear device

Technical field

The utility model is related to diesel locomotive, and specifically one kind prevents brake shoe partial wear device.

Background technology

Clasp brake diesel locomotive is mainly engaged in shunting service, due to rail track limitation, frequently falls and modulates dynamic, accelerates The abrasion of each leverage friction pair, increase the gap of each leverage, and between these member structures also have design in design, assembling Gap and assembly clearance, these gaps are reflected in the lump will produce very big gap error when on brake shoe, these gaps will be in braking When make the brake force that left and right sides obtains uneven, along with brake rigging itself has a standing transverse momentum, so as to produce lock Watt eccentric wear phenomenon.

The braking drag link system of former car design as shown in Fig. 2 because installation site is in the side of both sides wheel brake head, When checking cylinder is acted on, two external force certainly will be produced on the brake shoe stress point of both sides, brake shoe partial wear is caused in the course of time.

Wheel tread shape is made up of wheel rim and circular conical surface two parts, as shown in figure 3, belonging to worn profile tread, it is played Guide effect.Due to the influence of tread profile during locomotive brake, brake shoe will outwards be braked component by one, and 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 side after eccentric wear to limit After will scrap monoblock brake shoe, cause spare part significant wastage, cause Master Cost and maintenance cost 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, very big potential safety hazard is brought to driving.

Utility model content

In order to solve the above technical problems, the purpose of this utility model is to provide a kind of device for preventing brake shoe partial wear, specifically Technical scheme is as follows：

One kind prevents diesel locomotive brake shoe partial wear device, including pull bar, and the pull bar is symmetrical two-part structure, each Duan Jun includes forming groove in the middle of upper boom, lower beam and brace, pull bar；Two upper booms of pull bar are fixed on brake shoe by attachment means The centre position of support；The port of the lower beam is respectively provided with the flange and groove of mutual cooperation, also sets up through hole and pin hole；Gu Through-hole groove and multigroup pin hole be set in fixed board, and two lower beams of pull bar are by the bolt through 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 of pull bar, brace, lower beam.

The attachment means are：The end of upper boom sets the male cooperation of groove, the groove and brake head, and pin is passed through The through hole set on groove；The through hole is multigroup.

The utility model has the advantages that：Brake shoe partial wear phenomenon is eliminated, and locomotive operation is good, and be substantially prolongs than before The service life of brake shoe, while reducing locomotive inspection and repair and using cost, alleviates the labour intensity of workman, improves locomotive Integrated use rate, eliminates traffic safety hidden danger.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model；

Fig. 2 is prior-art illustration；

Fig. 3 is wheel tread shape figure.

Specific embodiment

The utility model is illustrated below in conjunction with the accompanying drawings, as shown in figure 1, the utility model includes pull bar 3, the pull bar 3 is symmetrical two-part structure, and each section includes forming groove in the middle of upper boom 31, lower beam 33 and brace 32, pull bar, to hide Open universal drive shaft 2；Two upper booms 31 of pull bar are fixed on the centre position of brake head 1 by attachment means 4；The end of the lower beam 33 Mouth is respectively provided with the flange 8 and groove 9 of mutual cooperation, also sets up through hole and pin hole；Through-hole groove and many is set in fixed plate 11 Group pin hole, two lower beams 33 of pull bar are fixed into one by the bolt 10 through the through hole and the pin 6 through pin hole Body；For the turning for preventing pull bar 3 occurs angle change and then influences the two ends length of pull bar 3；Anti- torsion bar 7 is also set up, it is described Anti- torsion bar 7 is fixed on the upper boom 31 of pull bar, brace 32, lower beam 33 by axle 12, and so, pull bar is formed the triangle of stabilization Shape attachment structure.

For ease of the length at adjustment pull bar two ends, the attachment means 4 are：The end of upper boom 31 sets groove, described recessed The male cooperation of groove and brake head, through hole 5 of the pin 6 through setting on groove；The through hole 5 is multigroup.The attachment structure can By the length that pin is arranged on different through hole adjusting yoke two ends；And the attachment structure in lower beam and fixed plate, due to There is provided multiple pin holes, it is also possible to adjust the length at pull bar two ends；Two adjusting meanss cooperate, and are easy to easily combine Into different length.

In order to obtain superior technique effect, can be by each leverage in the brake rigging of clasp brake diesel locomotive Nylon jacket changes steel bushing into.Rigidity, the intensity of sleeve pipe when so both can guarantee that braking, can reduce the deformation of guide again, reduce each bar Activity between system, lever, brake shoe produce swing when not causing braking.

Claims (2)

1. one kind prevents diesel locomotive brake shoe partial wear device, it is characterised in that：Including pull bar, the pull bar is symmetrical two-part Structure, each section includes forming groove in the middle of upper boom, lower beam and brace, pull bar；Two upper booms of pull bar pass through attachment means It is fixed on the centre position of brake head；The port of the lower beam is respectively provided with the flange and groove of mutual cooperation, 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 bar are by the bolt through the through hole And be integrally fixed through the pin of pin hole；Also set up anti-torsion bar, the anti-torsion bar be fixed on the upper boom of pull bar, brace, under On bar.
