Abstract

The utility model belongs to the hoisting apparatus technology, and relates to a windproof security device running the hoisting apparatus on outdoor rails, in particular to a novel wedge type of wheel limit stop. The utility model is characterized in that a series of drive links hinged together are arranged between the active rocker and the wedge; the positioning of the wedge at a specific position is completed by a pothook. The bracket, the electric power hydraulic pusher, the active rocker and the support shaft are hinged together in sequence. The support shaft is in rigid connection with the passive rocker. The passive rocker, the connecting rod, the triangle swing stem, a horizontal rod and the steeve are hinged together in sequence. The wedge is hinged with the horizontal rod through a round orifice and a slotted hole. The wedge, two ends of the support shaft, the elbow of the triangle swing stem and the upper part of the steeve are respectively hinged with the bracket. The wedge of the utility model slides horizontally along the place close to the wheel and is ensured to prop up the wheel when being pushed and save labor without being blocked or resisted when being pulled out. The wedge is positioned by the pothook after being lifted; the limit stop can work without electricity; therefore the electric power is saved and the service life of the limit stop is prolonged.

Description

Wedge-type wheel hill holder

Technical field

The utility model belongs to the weight-lifting equipment technical field, relates to the windproof safety device of operation weight-lifting equipment on the outdoor rail, specially refers to a kind of novel Wedge-type wheel hill holder.

Background technology

The Wedge-type wheel stop motion mechanism of having used at present has following weak point, and (1) can not guarantee accurately to prop up wheel when voussoir falls, and needs compensating device and makes equipment voussoir when being subjected to displacement just can touch wheel; And be clipped in the directly operation obliquely upward when mentioning of voussoir between track and the wheel, easily produce the jam phenomenon.(2) mentioning always of voussoir continues to support by electro hydraulicthruster, and power hydraulic pressure promotes as works for a long time, and the internal electrical chance produces overheated and easily causes fault.

Summary of the invention

The purpose of this utility model is to overcome above technical deficiency, and a kind of novel Wedge-type wheel hill holder is provided.Be mainly used in the weight-lifting equipment that moves on the outdoor rail in back out of service stop wheel rapidly, prevent to slip the car accident because of external force effects such as wind-force.

The technical solution of the utility model is that this hill holder mainly is made of a series of drive links that are hinged between support 1, electro hydraulicthruster 2 and initiatively rocking arm 5 and the voussoir 13, and finishes the location of voussoir 13 at ad-hoc location by hook 8.Electro hydraulicthruster 2 bottoms and support 1 are hinged; Top and initiatively rocking arm 5 are hinged, and the initiatively rocking arm 5 that is provided with driving lever 4 can rotate around pivot shaft 3, and passive rocking arm 6 is rigidly connected with pivot shaft 3, and connecting rod 7 upper ends and the passive rocking arm 6 that are provided with bayonet lock 9 are hinged; Lower end and triangle fork 10 transverse arms are hinged, and triangle fork 10 ancons and support are hinged; Its trailing arm and horizon bar 12 are hinged, and suspension rod 11 upper ends and support 1 are hinged; The lower end is hinged by slotted hole and horizon bar 12, and voussoir 13 middle parts and horizon bar 11 are hinged; Left end is also hinged with horizon bar 11 by slotted hole.The hook 8 that is provided with special-shaped groove and back-trough is hinged with support 1.See Fig. 1～Fig. 3.

Effect of the present utility model and benefit are: (1) voussoir is in the slip that one section horizontal direction is arranged near the wheel place, and the voussoir level slides into when advancing voussoir, guarantees accurately to prop up wheel; The voussoir level skids off when pulling out voussoir, and is laborsaving and do not have a jam phenomenon.(2) voussoir 13 is mentioned the back by hook 8 location, and hill holder does not have electricity work, has not only saved electric power resource but also improved the service life of hill holder.

The specific embodiment

Below in conjunction with technical scheme and accompanying drawing, be positioned by voussoir and hang up and two steps that voussoir was released and propped up wheel are described in detail the specific embodiment of the present utility model.

One, Fig. 4～Fig. 7 is seen in the voussoir hang-up that is positioned.

Energising, electro hydraulicthruster 2 is jack-up initiatively rocking arm 5 first; Driving lever 4 on the initiatively rocking arm lifts passive rocking arm 6 around bolster 3 clickwises; Connecting rod 7 upward movements; Bayonet lock 9 is along with upward movement, and hook 8 is subjected to bayonet lock 9 thrust around K axle left-hand revolution; Triangle fork 10 is around E axle clickwise; Suspension rod 11 is around F axle clickwise; Horizon bar 12 moves to the upper left side, because suspension rod 11 lower ends and voussoir 13 left end settings is slotted hole, makes horizon bar 12 when dragging voussoir 13, and voussoir 13 could move to the upper left side after wheel 15 1 segment distances are left in track 14 horizontal slips earlier.

After electro hydraulicthruster 2 reached upper limit position, outage fell after rise; Under the action of gravity of a series of drive links, initiatively rocking arm 5 and passive rocking arm 6 are around pivot shaft 3 left-hand revolutions; Connecting rod 7 moves downward, and links up with 8 by gravitys around K axle clickwise; Bayonet lock 9 is taken advantage of a situation and is slided into hook 8 special-shaped trench bottoms and be stuck, and each rod member is stop motion, voussoir 13 hang-up that is positioned.Electro hydraulicthruster 2 and initiatively rocking arm 5 continue to fall back to initial position.Voussoir 13 hang-up that is positioned, equipment is free-running operation in orbit.

Two, voussoir is released and props up wheel, sees Fig. 8～Figure 11.

Energising, electro hydraulicthruster 2 is jack-up initiatively rocking arm 5 once more; Driving lever 4 touches passive rocking arm 6 and drives it around pivot shaft 3 clickwises; Connecting rod 7 upward movements; Bayonet lock 9 is linked up with 8 by gravitys around K axle clickwise along with upward movement; Bayonet lock 9 just rises up into the flank of hook 8 special-shaped grooves.

At this moment electro hydraulicthruster 2 has reached upper limit position, and outage falls after rise; Under the action of gravity of a series of drive links, initiatively rocking arm 5 and passive rocking arm 6 are around pivot shaft 3 left-hand revolutions; Connecting rod 7 moves downward, and bayonet lock 9 is along with moving downward and skidding off by linking up with 8 back-trough; Triangle fork 10 is around E axle left-hand revolution; Suspension rod 11 is around F axle left-hand revolution; Horizon bar 12 and voussoir 13 move to the lower right simultaneously.Because the setting of suspension rod 11 lower ends and voussoir 13 left end slotted holes makes voussoir 13 before not touching wheel 15, at first fall on the track 14, and continue to advance voussoir 8 until propping up wheel 15 by hinge J along track 14 levels by horizon bar 12.Wheel 15 is propped up, and can not roll and can not slide, and realizes the stop purpose.
