Abstract
The utility model discloses a handle clutch device for a point switch, and belongs to the rail point switch field. A drive device in the prior art is of the rigid connection, a slider beats and rubs on a cam or enters difficultly a clutch slot when switching electrically or switching manually, causing the disadvantages that the switching turnout is not switched. Based on the structure of the prior art, key arc surfaces 11 are arranged symmetrically on the cam to be used for the mechanical unlocking and locking, a circular arc 12 is used for the electric sliding, a slot is arranged on the clutch, the slider is provided with a locking component and a spring. After adopting the technical proposal, the failures that the switching turnout cannot be switched when sliding are eliminated, and the manually normal and continuous switchover of the point switch can be ensured.
Description
Technical field
The utility model relates to a kind of switch machine handle clutch equipment, is used for the railroad turnout cross travel, belongs to the railway switch apparatus field.
Background technology
In railway traffic, existing switch machine handle clutch equipment is rigid connection, the drive disk assembly of its clutch equipment, and promptly release between slider pad and the power-transfer clutch and locking are the rigidity frictions.Slider pad can not art skating when manual or electronic conversion.Chinese patent 95212626.5 discloses a kind of interchange switch machine handle clutch equipment, and the drive disk assembly of this device is rigid connection, during electronic conversion, and the slider pad friction of on cam, beating; During manual switch, mechanical locking cutting slider pad is difficult to enter the clutch tank, and it is not enough perhaps to enter the degree of depth, causes slider pad power-transfer clutch notch and goes out; The mechanical release slider pad is scraped the power-transfer clutch notch especially and is gone out; Must cause manual handle to skid and to change switch breakdown.
Summary of the invention
It is non-slip, safe and reliable in when conversion that the purpose of this utility model provides a kind of guarantee handle clutch equipment, guarantees that release and locking switch breakdown can not occur changing freely between the drive disk assembly.
In order to realize above-mentioned target, its technical scheme is: on the prior art constructions that comprises cam, power-transfer clutch, slider pad, spring, turning cylinder, handle, cam is provided with the crucial cambered surface 11 of symmetric arrangement, be used for release and locking, a circular arc 12 is used for electronic sliding, power-transfer clutch is provided with groove 21, and slider pad is provided with locking and spring is housed.
When manual switch, in mechanical locking or the releasing process, locking that cam 11 cambered surfaces hold up slider pad is put in the clutch tank 21 or locking is held up and freely leaves clutch tank 21, guarantees that locking do not scrape notch; Manually during contraposition, cam 12 cambered surfaces are guaranteed empty moving the sliding of slider pad.During electronic conversion, 13 of cam holds up slider pad, and it is empty moving that main shaft drives power-transfer clutch.
Compared with prior art, having eliminated during the work of this device skids can not change the fault of track switch, can guarantee the conversion that switch machine is manually normal, continue.This device drive disk assembly has increased conversion intensity, can be used for heavy rail (60kg/m) large size track switch going up and uses.In addition, this device is used to exchange switch machine, also can be used for direct-current point machine.
Description of drawings
Fig. 1 is the cam structure figure in the switch machine handle clutch equipment of the present utility model.
Fig. 2 is the clutch configuration figure in the switch machine handle clutch equipment of the present utility model.
Fig. 3 is the floating block structure figure in the switch machine handle clutch equipment of the present utility model.
Fig. 4 is the general assembly drawing of switch machine handle clutch equipment of the present utility model.
In Fig. 4,1 is that cam, 2 is that power-transfer clutch, 3 is that slider pad, 4 is that slider pad spring, 5 is that main shaft, 6 is handle.In Fig. 1,11 is the circular arc in the cam 1, and 12 is the circular arc in the cam 1, and 13 is the circular arc in the cam 1.In Fig. 2,21 is the groove in the power-transfer clutch 2.
The specific embodiment
With reference to Fig. 1, Fig. 4, the structure of cam 1 as shown in the figure, diameter is 130mm, thick in 63mm.A spindle hole, a microswitch driving hole, three bolt holes, 1 awl lockhole are arranged on it.Crucial cambered surface on the cam has 11, is two cambered surfaces of symmetric arrangement, is used for release and locking, and the 12nd, big cambered surface is used for empty moving the sliding of handle contraposition, and 13 are used to hold up slider pad.Because 11,12 cambered surfaces are often rotated, need surface hardening to handle.
Handle 6 is mentioned 15 degree mechanical lockings, pulls 150 degree conversion track switches, pulls 15 degree mechanical releases.
With reference to Fig. 4, cam 1 is fixed on the turn-out track casing, and power-transfer clutch 2 is connected with main shaft 5, and slider pad spring 4 is enclosed within on the slider pad 3, and is contained in the handle 6, the locking of slider pad and power-transfer clutch driving surface 2mm, the driving surface flush fit of the planing surface of slider pad 3 and cam 1; One end of main shaft 5 is by screw fixed handle clutch equipment, and the other end connects the switch machine driving cam.
In order to be illustrated more clearly in switch machine handle clutch equipment ground structure feature, special service condition with it is described below:
During electronic conversion, slider pad locking has left power-transfer clutch because of 13 on the cam holds up, and it is empty moving that main shaft drives the power-transfer clutch rotation;
During manual switch, handle mention 15 the degree mechanical lockings, promptly the planing surface of slider pad be close to cam 11 cambered surfaces slide 15 the degree, make sliding shoe locking not contact the power-transfer clutch notch and low water; Handle is pulled 150 degree again, and locking is stirred power-transfer clutch and driven main axis rotation 150 degree, makes railway switch tongue cross travel, opens another access; Handle is pulled 15 degree mechanical releases again, and promptly the planing surface of slider pad is close to another 11 cambered surface of cam and is slided 15 degree, makes locking not contact the power-transfer clutch notch and goes out groove; Handle action 180 degree have been finished and have once been changed the track switch function.If want track switch to get back to original position, handle clutch equipment working process is identical.During the handle contraposition, locking slides on cam 12 cambered surfaces, and contraposition back handle clutch equipment working process is same as described above.
Above-mentioned specific embodiments is a preferred embodiment of the present utility model.By description to above-mentioned working condition, illustrate that also this device can not produce slider pad and scrape the clutch tank and scrape the cam phenomenon when electronic, guarantee railway security thereby remove fault.
