Abstract

The utility model relates to a fast-mounted and demounted switch hooking and locking machine which is a special apparatus for locking a railway switch to be unable to unclose casually. The utility model is composed of more than ten members which are a hook screw rod (tooth-shaped rod), a movable hook, an add-forced cam, a hook body, a cam shaft, a spanner, a fastening block, etc. The action principle of the utility model is similar to that of a lathe brake block or a ratchet wheel. Compared with the ordinary switch hooking and locking machine, the utility model is fast and convenient to mount and demount and has the advantages of time saving, labor saving and strong versatility in operation.

Description

Load and unload the track switch hook lock fast

The utility model relates to a kind of switch locking mechanism that guarantees railway traffic safety.

The common hook lock that is used for the locking railway switch is at present colluded with horned nut by hook-shaped screw rod, activity to be formed.When horned nut clockwise rotates on hook-shaped screw rod, activity colluded push ahead, collude to collude until the end of hook-shaped screw rod and catch on the track switch flange of rail simultaneously with activity, and any one aperture on the horned nut is aimed at the movable aperture that colludes, lock switch locking.This hook lock is simple in structure, but loads and unloads time-consumingly, and inefficiency as screw rod and nut corrosion, or is blocked by dirt, and it is more inconvenient to operate.

The purpose of this utility model is to be similar to lathe brake shoe or ratchet principle for avoiding above-mentioned the deficiencies in the prior art to propose a kind of action principle, have when operation install or remove rapidly, convenient, highly versatile, same as the quick loading and unloading track switch hook lock of advantages such as hook lock can use on any one kilogram/meter track switch.

The purpose of this utility model can reach by following measure: the utility model is except that comprising that hook-shaped screw rod (thread form bar) and activity are colluded, with colluding body and being installed in the fastening block that colludes on the body, camshaft, the reinforcement cam, key, members such as spanner substitute the horned nut of common hook lock, its action principle is similar to lathe brake shoe or ratchet principle, when spanner is parallel with hook-shaped screw rod, fastening block is depressed, the thread form in its aperture is meshed with the thread form of hook-shaped screw rod, two reinforcement cams also collude activity extruding forward simultaneously, hook lock tightly colludes on the flange of rail of track switch both sides, and track switch is by locking; When spanner and hook-shaped screw rod were orthogonal, fastening block was upspring and is left hook-shaped screw rod, and two reinforcement cams also leave activity simultaneously and collude, at this moment, activity is colluded and is colluded body and can move freely along hook-shaped screw rod, and hook lock is unloaded, and track switch is unlocked.

Describe concrete structure of the present utility model and working condition in detail below in conjunction with accompanying drawing:

The utility model by hook-shaped screw rod (1), activity collude (2), reinforcement cam (3), collude body (4), camshaft (5), key (6), spanner (7), fastening block (8), steel ball (9), spring (10), key (11), screw (12) form.Hook-shaped screw rod (1) is the thread form bar, the material ordinary steel.The top that (2) are colluded in activity is pincerlike, and the centre is given boxing out and is used to install hook-shaped screw rod (1), and the bottom is colluded activity (2) and colluded body (4) flexible connection, material cast steel with screw (12).Two reinforcement cams (3) are large semi-circular, be installed in the two ends of camshaft (5) respectively, and with key (11) chucking fixing (accompanying drawing 5), fastening block (8) is one to be drilled with the cylindrical of the region between the heart and the diaphragm hole along axis direction, the end, aperture is a thread form, this thread form is meshed with the thread form of hook-shaped screw rod (1), and spring (10) and steel ball (9) are housed in the hole, and material is with No. 45 steel.Collude body (4) and have three holes: one is the vertical equity hole, is used to install hook-shaped screw rod (1); Another be positioned at collude body (4) front end bossing and with the vertical vertical core that communicates of lateral aperture, be used to install fastening block (8); The 3rd hole is to be positioned at the upper end of colluding body (4) bossing, and be vertical with the vertical equity hole and pass the transverse horizontal hole of vertical core, is used to install camshaft (5), colludes body (4) and cylinder iron hole behind the moulding by casting.The section of key (6) is flute profile, and the key hole is established on biside plate top, and the base is given and stayed screw, with plain screw key (6) is fixed on the platform that colludes body (4) rear end.One end of spanner (7) has screw thread, is installed in giving of camshaft (5) middle part box out material A ₂Number steel.

The thread form bar of hook-shaped screw rod (1) also can be made threaded rod or channel-shaped bar, but should note the orifice shapes of fastening block (8) is made corresponding change, so that fastening block (8) can mesh with hook-shaped screw rod (1) when work.

Key (11) also can be used neat seam screw instead.

Referring to Fig. 1, Fig. 2

During locking track switch, (2) are colluded in hook-shaped screw rod (1) and activity catch on the track switch flange of rail simultaneously, with spanner (7) pull to the parallel position of hook-shaped screw rod (1), this moment, the cam of camshaft (5) mid portion was depressed fastening block (8), the thread form of fastening block (8) orifice end and the thread form of hook-shaped screw rod (1) engagement (accompanying drawing 2), two reinforcement cams (3) also collude activity (2) simultaneously and push forward, reach the tight effect of colluding, track switch is lockable, for preventing that the people from losing the locking effect for pulling spanner, available common iron lock penetrates the key hole with spanner.Locking.

Referring to Fig. 3, Fig. 4

During release, with spanner (7) pull to the perpendicular position of hook-shaped screw rod (1), because loosening, the spring (10) in fastening block (8) hole separates this moment by (accompanying drawing 4) with fastening block jack-up and with hook-shaped screw rod (1), two reinforcement cams (3) are half-twist and (2) are colluded in the disengaging activity simultaneously also, activity is colluded (2) and is set back, at this moment, activity is colluded (2) and is colluded body (4) and can be free to slide on hook-shaped screw rod (1), hook lock is unloaded, and track switch is unlocked.

Referring to Fig. 6

Lightweight loads and unloads the track switch hook lock fast, be that reinforcement cam of the present utility model (3) is removed, activity is colluded (2) and collude body (4) and be integrated, its action principle is identical with the utility model with performance, does not need the area that track switch is tightly killed when being applicable to locking track switch.
