Detailed description of the invention
For fully understanding the purpose of this utility model, feature and effect, existing by following specific embodiment, and coordinate accompanying drawing, the utility model is described in detail as follows:
As shown in Figure 2, electrodes in mine hot stove of the present utility model is stuck with paste gig disconnected rope safety guard and is comprised: lifting rope seat 4, telescopic pin 3, control steel rope 1 and turn to rope seat 5.Wherein, lifting rope seat 4 is fixedly installed on the central authorities at gig lifting platform 8 top, this lifting rope seat 4 comprises the shell 41 of a hollow and to be horizontally set in this shell 41 and the reel for rope 7 that can slide up and down along the shell wall of shell 41, and the hoisting wirerope 2 of gig is vertically fixed on described reel for rope 7 by wire rope grip.The shell wall top of described shell 41 is provided with the first locating part 42 that restriction reel for rope 7 slides, bottom is provided with the second locating part 43, between above-mentioned two locating parts, there is a distance Y, described reel for rope 7 slides up and down between above-mentioned two locating parts, and namely the shift motion of this reel for rope 7 is Y.In addition, the two ends of described reel for rope 7 have the becket bridle 71 given prominence to outside shell 41, and becket bridle 71 is connected with and controls steel rope 1, the other end of described control steel rope 1 is fixed in telescopic pin 3.
As shown in Figure 2 to Figure 3, telescopic pin 3 is the positions being arranged on described lifting platform 8 top, close gig derrick, mainly plays the effect that braking lifting platform prevents it from dropping.In the present embodiment, described telescopic pin 3 is arranged on four angles at lifting platform 8 top.Further, as shown in Figure 6 to 7, described telescopic pin 3 has the tubular pin cylinder 36 of hollow, and its two ends are coaxially provided with the first orienting sleeve 34 and the second orienting sleeve 37 with opening respectively, and the diameter of described opening is less than the diameter of pin cylinder 36.Telescopic shaft 32 is located in described pin cylinder 36, and it has first end 321 and the second end 322.Wherein, first end 321 stretches out the opening of the first orienting sleeve 34, and this first end 321 has the set collar 31 of fixing above-mentioned control steel rope 1.Described telescopic shaft 32 is coaxially provided with baffle ring 33 near its medium position, and the diameter of this baffle ring 33 is greater than the diameter of the opening of the first orienting sleeve 34 and the second orienting sleeve 37.The outside of telescopic shaft 32 is arranged with spring 35, and one end contact of spring 35 is on baffle ring 33, and other end contact is on the first orienting sleeve 34.When spring 35 is in compressive state, the second end 322 is positioned at the second orienting sleeve 37; When spring 35 is in release position, baffle ring 33 contact is on the second orienting sleeve 37, and the second end 322 stretches out the opening of the second orienting sleeve 37 and offsets to brake lifting platform 8 with gig derrick panel.Become in the process of release position at described spring 35 from compressive state, namely the distance that telescopic shaft 32 has flexible stroke X, this flexible stroke X is that baffle ring 33 is promoted the distance of movement by spring 35.Further, this flexible stroke X equals the sliding distance Y of above-mentioned reel for rope 7.
As shown in Fig. 2, Fig. 3 and Fig. 5, for gentle transition controls steel rope 1, reduces the conicity force of telescopic pin 3 as much as possible and make to stretch bearing pin 32 reciprocating action more smooth and easy, position between lifting rope seat 4 and telescopic pin 3 is also provided with and turns to seat 5 of restricting, it has a pair stay bearing plate 51 be vertically set on lifting platform 8 top, and two ends connect the rotating slewing rollers 52 of two stay bearing plates 51 respectively, there is between these slewing rollers 52 and lifting platform 8 top a passage 53.One end of described control steel rope 1 is fixedly connected on the becket bridle 71 of described reel for rope 7, and the other end is connected on the set collar 31 of described telescopic pin 3 through described passage 53.The end face that described control steel rope 1 is placed in the part of passage 53 contacts with the bottom surface of slewing rollers 52.Control steel rope 1 and slewing rollers 52 friction of rolling, effectively can prevent the fracture controlling steel rope 1.In addition, this turns to the height of rope seat 5 to be less than or equal to the rational height of described telescopic pin 3, matches, the vertical tension of hoisting wirerope 2 is become horizontal pull with control steel rope 1 and reel for rope 7, to control the flexible of telescopic shaft 32.
What deserves to be explained is, the manufactured materials of above-mentioned reel for rope 7 is 40Cr, has very high comprehensive mechanical performance after modified.Above-mentioned slewing rollers 52 and telescopic shaft 32 all select modified 45# steel to do; Spring 35 is made by spring steel 60SI2MnA.These materials application extensively, dependable performance and with low cost.
In addition, the utility model also can arrange base 6 at the top of lifting platform 8, and by lifting rope seat 4, turn to rope seat 5 and telescopic pin 3 be fixedly installed on this base 6.
When lifting platform 8 handling of the present utility model is housed, when hoisting wirerope 2 does not rupture, weight due to lifting platform 8 self makes hoisting wirerope 2 tighten, now reel for rope 7 is pulled to the first locating part 62 place (i.e. the vertex of its vertical stroke Y), thus tension controls steel rope 1, and then pull the first end 321 of the telescopic shaft 32 in described telescopic pin 3, make it away from the first orienting sleeve 34, thus drive the second end 322 to retract in the second orienting sleeve 37, meanwhile, baffle ring 33 is to the first orienting sleeve 34 direction Compress Spring 35.So, lifting platform 8 normally can carry out handling work.When hoisting wirerope 2 ruptures suddenly, reel for rope 7 falls to the second locating part 63 place (i.e. the nadir of its vertical stroke Y) owing to losing pulling force, order controls steel rope 1 and no longer tightens, thus make spring 35 abrupt release baffle ring 33 be pushed to the direction of the second orienting sleeve 37, and then the second end 322 promoting telescopic shaft 32 stretches out the second orienting sleeve 37 and is against on the crossbeam of lift headframe, to ensure that lifting platform can not fall.
Can be understood as, the utility model is described by some embodiments, and those skilled in the art, when not departing from spirit and scope of the present utility model, can carry out various change or equivalence replacement to these characteristic sum embodiments.In addition, under instruction of the present utility model, can modify to adapt to concrete situation and material to these characteristic sum embodiments and spirit and scope of the present utility model can not be departed from.Therefore, the utility model is not by the restriction of specific embodiment disclosed herein, and the embodiment in the right of all the application of falling into all belongs to protection domain of the present utility model.
