Further, the initiating terminal of described rope is connected to the upper limb of described cutting means enclosure, and the end of described rope is walked around lower edge and the described fixed pulley sliding block joint of described cutting means enclosure.
Further, described rope is steel rope.
Further, described cutting means enclosure comprises the many fender rods that be arranged in parallel and connects many chains of described fender rod.
Further, described cutting means enclosure comprises that 7 are horizontally disposed with fender rod, and the spacing between described fender rod is 150mm-250mm.
Further, described fender rod is steel pipe.
Further, the spacing between described chain is 400mm-600mm.
The protective device for Ma Dier self-advancing tail device that the utility model provides can form safety curtain between Ma Dier self-advancing tail device and operating personal, make operating personal and operating equipment keep certain safety distance, thereby the safety that guarantees production is carried out, and this protective device is simple in structure, easy to operate, contribute to reduction operation personnel's labour intensity.
Accompanying drawing explanation
Fig. 1 is the cutting means enclosure schematic diagram of a kind of preferred protective device for Ma Dier self-advancing tail device of the utility model;
Fig. 2 is the capstan winch schematic diagram of a kind of preferred protective device for Ma Dier self-advancing tail device of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, a preferred embodiment of the present utility model is described in detail.Wherein identical parts represent with identical Reference numeral.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometric centre.
As depicted in figs. 1 and 2, the protective device for Ma Dier self-advancing tail device that the utility model provides comprises the cutting means enclosure 1 and the fixed pulley 2 that are hung on described Ma Dier self-advancing tail device outlet, on described cutting means enclosure 1, be connected with the rope 3 for cutting means enclosure described in pull-up 1, described rope 3 is dynamically connected with described fixed pulley sliding 2, while pulling described rope 3, described cutting means enclosure 1 can be scrolled up, otherwise, while unclamping described rope 3, described cutting means enclosure 1 can be spread out downwards.Certainly, in order to simplify the operation, reduce the labour intensity of operating personal, the end of rope 3 of the present utility model is connected with capstan winch 4, and operating personal can pass through to control the hand of rotation of described capstan winch 4, thereby realizes lifting or the decline of cutting means enclosure.
When personnel need to enter belt operation, only need by Manual tightening capstan winch 4, drive rope 3 by slow cutting means enclosure 1 pull-up; At production period; operating personal can become flexible capstan winch 4 by reversing sense, and cutting means enclosure 1 is slowly put down, and sets up one deck barrier between implement and operating personal; make operating personal and equipment in service keep certain peace to go distance, thereby play the object of protection personal security.
As a kind of preferred version of the present utility model, as shown in Figure 1, the initiating terminal of the rope 3 of the present embodiment is connected to the upper limb of described cutting means enclosure 1, and the end of described rope 3 is walked around lower edge and described fixed pulley 2 sliding block joints of described cutting means enclosure 1.Need to rise described cutting means enclosure 1 time, operating personal rotates described capstan winch 4, pull described rope 3, described rope 3 moves up under the directional tagging of described fixed pulley 2, because the initiating terminal of described rope 3 is fixed on described Ma Dier self-advancing tail device outlet, along with the movement of described rope 3, the lower edge of described cutting means enclosure 1 under described rope 3 drives by pull-up gradually and rise, otherwise, rotate backward described capstan winch 4, decontrol described rope 3, described cutting means enclosure 1 is not having under rope 3 gathering effects, dependence self gravitation naturally droops, thereby realize the decline of cutting means enclosure.
In order to make cutting means enclosure 1 rise or to decline to uniform and stable, the present embodiment arranges many ropes 3 in the direction of the rising perpendicular to described cutting means enclosure 1 or decline, correspondingly, above every rope, be also provided with fixed pulley 2, after rope 3 and fixed pulley 2 sliding block joints, be connected on capstan winch 4, fixed pulley 2 can change the lead of rope 3, makes many ropes 3 under the rotation traction of capstan winch, all can pull described cutting means enclosure 1 towards direction straight up.
Consider rope 3 of the present utility model cutting means enclosure 1 rise and decline process in need to be subject to larger friction force, in order to improve intensity and the wear resisting property of rope 3, the rope 3 of the present embodiment is preferably steel rope, certainly, steel rope is only a kind of preferred version of the utility model rope 3, the utility model can also adopt other rope with sufficient intensity and wear resisting property known in those skilled in the art, repeats no more herein.
As a kind of preferred version of the present utility model, as shown in Figure 1, the present embodiment cutting means enclosure 1 comprises the many fender rods that be arranged in parallel 11 and connects the many chains 12 of described fender rod 11, and the fender rod 11 of the present embodiment is preferably steel pipe.Consider the height of conventional Ma Dier self-advancing tail device, the cutting means enclosure 1 of the present embodiment preferably includes 7 and is horizontally disposed with fender rod 11, spacing between described fender rod 11 is preferably 150mm-250mm, the chain 12 of the present embodiment arranges perpendicular to described fender rod 11, spacing between described chain 12 is preferably 400mm-600mm, the present embodiment adopts chain 12 to connect fender rod 11, not only can guarantee protection effect, can also effectively improve the flexibility ratio of cutting means enclosure 1, thereby avoid being damaged in Ma Dier self-advancing tail device passing process.
To sum up, the protective device for Ma Dier self-advancing tail device that the utility model provides can form safety curtain between Ma Dier self-advancing tail device and operating personal, make operating personal and operating equipment keep certain safety distance, thereby the safety that assurance is produced is carried out.And because this device is formed by connecting by chain by many root guards bar, therefore flexibility ratio is larger, even be also difficult for causing damage in Ma Dier self-advancing tail device passing process.
