Abstract
The utility model relates to a stochastic automatic stretching safety device of a reversed loader. The stochastic automatic stretching safety device mainly solves the technical problems of poor safety protection effect and requirement of manual operation of the existing safety device. The technical scheme of the stochastic automatic stretching safety device is that the stochastic automatic stretching safety device of the reversed loader comprises a connecting plate telescoping mechanism, a protective screen and fixed connecting mechanisms at two ends, wherein the connecting plate telescoping mechanism is composed of a plurality of connecting plates which are connected with each other via a hinge pin shaft; the protective screen is composed of annular chains linked together; the left end of each of the fixed connecting mechanisms at two ends is composed of a left universal connecting mechanism, a left fixing frame, a lead rail and a hoop; the right end of each of the fixed connecting mechanisms at two ends is composed of a right universal connecting mechanism, a right fixing frame, a rack and a lead rail, and the lead rail is a rectangular lead rail. The stochastic automatic stretching safety device has the advantages that the stochastic automatic stretching safety device is simple and practical in structure, good in safety protection performance and the like, and can automatically stretch at random.
Description
Technical field
The utility model relates to the corollary apparatus of elevating conveyor in a kind of comprehensive extracting and caving face, and more particularly, the utility model is at random automatic retractable safety protector of a kind of elevating conveyor.
Background technology
In the whole supporting layout of comprehensive extracting and caving face equipment, the elevating conveyor both sides have ridden one group of face end support, in elevating conveyor monolateral groove material feeding section and face end support left side, be overlapped with the front and rear portions scratch board conveyor, elevating conveyor is then being undertaken the raw coal transportation of whole work plane.When work plane is pushed ahead, can alternately move forward along with the direction of propulsion mutual circulation of work plane between face end support, elevating conveyor and the front and rear portions scratch board conveyor.
Elevating conveyor is to prevent that larger coal cinder from entering main conveying system when transportation, at the elevating conveyor middle part PCM400 set hammer formula crushing engine is installed, so the material receiving area segment limit at elevating conveyor carries out the personnel of operation in case carelessness is strayed in the elevating conveyor, will cause great human casualty accident.According to " safety regulations in coal mine " the 9th section of the 67 article regulation: when the work plane elevating conveyor is equipped with crushing engine, safety device must be arranged.
The safety device of at present elevating conveyor employing has the patterns such as expansion link, ratchet reel type protective chain and common protective chain, and in use there are the following problems: because expansion link is rigidity, can't stretch, lower side space is excessive, the security protection weak effect.Ratchet reel type protective chain and common protective chain all use three small-sized round-link chains, utilize the reducer of front and rear portions transporter to fix foundation frame and ratchet drum mechanism built for basic point design, and protective chain is connected between the front and rear portions transporter.Although three protective chain has certain shield structure, but push ahead at work plane, replace between each equipment when moving, the mechanism of ratchet reel or three protective chains all need the artificial operation of removing, comparatively loaded down with trivial details, also stayed potential safety hazard in the time of after the releasing.
Summary of the invention
The purpose of this utility model is the manually-operated that needs that solves existing safety device existence, and the technical problem of security protection weak effect provides at random automatic retractable safety protector of the high elevating conveyor of the good automaticity of a kind of safety.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be:
Elevating conveyor is the automatic retractable safety protector at random, comprise the connecting plate telescoping mechanism, protective screening is fixedly connected with mechanism with two ends, wherein: described connecting plate telescoping mechanism is interconnected several connecting plates by hinging pin shaft and forms, described protective screening is formed by the round-link chain link, and with bolts with the lower end of connecting plate telescoping mechanism, described two ends are fixedly connected with the left end of mechanism by left Universal connecting mechanism, left fixed mount, guide rail and clip form, left Universal connecting mechanism is the long trough opening, be hooked on the left fixed mount, guide rails assembling is on left fixed mount, and left fixed mount and clip are welded to connect, and described two ends are fixedly connected with the right-hand member of mechanism by right Universal connecting mechanism, right fixed mount, hanger and guide rail form, right Universal connecting mechanism band rectangle square hole also is connected with guide rail on the right fixed mount, and hanger is fixed on the right fixed mount.
Described guide rail is rectangular guideway.
Because the utility model has adopted technique scheme, mutually alternately moving the space segment that constantly changes that produces according to front and rear part transporter, elevating conveyor and face end support designs, designed at random automatic retractable safety protector of two groups of elevating conveyors at space segment, the connecting plate telescoping mechanism that uses, automatic telescopic does not need manual operation at random; Two ends are fixedly connected with the scope that moves horizontally that mechanism can realize and the amplitude of oscillation and can satisfy fully and alter the displacement that downslide produces on the work plane haulage device; Owing to be to pluck the connected mode of unloading, can guarantee like this when equipment downtime overhaul, can extract at any time this end, shrink and hang on the hanging rack special on the reducer, be convenient to personnel and pass in and out or transport the material and facility parts; Protective screening can be with work plane operating personnel and elevating conveyor isolation, and security protection performance is good.Therefore, compare with background technology, the utlity model has simple and practical, automatic telescopic at random, the advantage such as security protection performance is good.
