Description

[0001] The present invention relates to a flat belt equalizer for folding and extending a folding bridge,

The present invention relates to a passenger car which is provided with a first tunnel for providing an entrance passage and a second tunnel for providing a connection passage and a third tunnel for providing an exit passage, A means for guiding the telescopic expansion and contraction of the passenger tunnel in accordance with the traveling direction of the driving device connected to the third tunnel while the traveling wheel is provided, A folding unit disposed on a lower side of the boarding tunnel for folding the second tunnel and the third tunnel in cooperation with each other, a spreading unit disposed on the other side of the lower portion of the boarding tunnel for interlocking the second and third tunnels, To an equalizer for a stretching operation of a boarding bridge.

In general, a boarding school is arranged between an airport building and a passenger plane to provide a passageway for the passengers to move safely and conveniently from the airport building to the inside of the passenger plane without being affected by various weather conditions or outside environment, It has a structure capable of changing the length of expansion and contraction and exit direction according to the distance between the building and the passenger plane and the position of the door of the passenger aircraft.

More specifically, the boarding bridge includes a first tunnel providing an entrance passage with a connection to an airport building, a second tunnel providing a connection passage, and a third tunnel providing an exit passage to the passenger aircraft are connected to a telescope ), And a driving device connected to the third tunnel in a state of having a moving wheel. The main body of the tunnel is provided with a function of a rotating shaft so as to rotate the traveling tunnel in accordance with the position of the passenger plane , And a lift column for moving up and down the boarding tunnel in accordance with the size of the passenger plane and the position of the door.

When the third tunnel is pulled toward the front side or the rear side is pushed in by driving the driving device connected to the third tunnel in the above-mentioned boarding bridge, the second tunnel is interlocked with the third tunnel to the front side or the rear side, A device called an equalizer is applied so that the expansion and contraction of the tunnel can be stably performed. The equalizer is disposed at one side of the lower surface of the boarding tunnel, and is provided with a folding unit for folding the second and third tunnels, And a spreading unit disposed on the other side of the lower surface of the boarding tunnel for unfolding the second and third tunnels in cooperation with each other.

As a typical example of the equalizer, a first pulley installed on the bottom of the bottom of the outlet side of the second tunnel is pivoted to the upper side of the inlet side of the third tunnel with one side connected to the bottom of the inlet side of the first tunnel And a second pulley installed at a predetermined angle on the bottom surface of the inlet side of the second tunnel in a state where one end is connected to the bottom of the bottom of the outlet side of the first tunnel, And a second rope spreading unit that is pivotally connected to an upper portion of the bottom surface of the entrance side of the third tunnel and connected to the other end is disclosed in Korean Registration No. 10-0924212 (published on Oct. 29, 2009) have.

However, in the above-described conventional equalizer, since the folding unit and the spreading unit for performing the expansion and contraction operation of the boarding tunnel are composed of the wire rope and the pulley, And thus it was difficult to smoothly and smoothly perform the stretching operation of the boarding tunnel. In addition, frequent collisions or friction between the wire rope and the boarding tunnel caused damage to the wire rope So that the durability of the equalizer and the useful life of the equalizer are relatively short.

In order to solve the above problems, both ends of the wire rope are fixed to the lower surface of the tunnel, while each wire rope is pulled with a very strong force. On the other hand, It is necessary to install a plurality of support brackets for supporting the wire rope along with the installation of the equalizer. In addition to this, the equalizer installation work becomes complicated, and a lot of time and cost are required for the work. There is a problem that the wire rope is stretched and sagged continuously after the lapse of the period.

Particularly, in order to ensure safe use of the equalizer, maintenance work for applying oil to the surface of the wire rope which is susceptible to corrosion has to be carried out from time to time. When the third tunnel is folded to the first tunnel side together with the second tunnel When the third tunnel is pulled out of the first tunnel together with the second tunnel as the wire rope located below the bottom surface of the second tunnel comes into contact with the decorative carpet laid on the bottom surface of the passage of the third tunnel, And the bottom surface of the passage of the third tunnel is stained with oil.

As described above, if the oil stains of the carpet placed on the bottom surface of the passageway of the third tunnel are left unchanged, the passengers moving to the passenger aircraft through the passenger tunnel are discomforted. Therefore, the cleaning work for removing oil stains on the carpet In addition, since it is very difficult to remove oil stains from the carpet, it takes a lot of manpower and time for the cleaning work, and when the oil stains are heavily burnt, the carpet itself needs to be replaced with a new one. Which causes a considerable cost burden.

As a further matter, as the second rope constituting the spreading unit is pivoted from the outlet side of the first tunnel to the inlet side of the second tunnel to extend to the third tunnel side, the second pulley penetrates the bottom surface of the second tunnel obliquely There is a problem in that a position where the second pulley is installed must be selected so as to match the position where the second rope is connected so that the traveling route of the second rope does not deviate even when the second pulley is wound, Since the bracket supporting the second pulley in a sloped state and the rotation shaft are very likely to generate cracks due to a torsional load, the durability and service life of the equalizer including the spreading unit are further shortened.

Korean Patent No. 10-0924212

The folding unit and the spreading unit for the folding operation and the unfolding operation of the boarding tunnel are divided into two parts on the left and right sides of the lower surface of the boarding tunnel respectively, 1 tunnel is connected to the lower part of the bottom of the entrance side of the first tunnel, and the first belt drum is installed below the bottom of the exit side of the second tunnel, A folding unit is constituted by a flat belt and a second belt drum installed on an opening side bottom face of the second tunnel in a state where one end is connected to the bottom of the bottom of the outlet side of the first tunnel is turned, The second flat belt having the other end connected to the upper side of the side bottom surface constitutes the spreading unit.

On the other hand, in the state where the second tunnel 5 and the third tunnel 6 are folded toward the first tunnel 4 connected to the airport building as shown in Fig. 10 (a), the third tunnel 6, When the third tunnel 6 is moved forward (in the arrow direction) by operating the driving device 3 connected to the first tunnel 4, the outlet side end bracket 15a of the first tunnel 4 constituting the spreading unit 10b, Only the inlet side end bracket 15a of the third tunnel 6 moves together with the third tunnel 6 and pulls the second flat belt 12 forward, The second tunnel 5 in which the second belt drum 14 is fixed is also moved forward with the second belt drum 14 in the course of the second flat belt 12 being pulled by the second belt drum 14 In this way, the second tunnel 5 interlocks with the third tunnel 6 and is pulled toward the front side. As a result, as shown in FIG. 10 (B) Which will be put spreads the tunnel (2).

In addition, when the folding unit 10a performs folding operation of the boarding tunnel 2, tensile force is not applied to the second flat belt 12 of the spreading unit 10b, No tensile force is applied to the first flat belt 11 of the folding unit 10a even during the unfolding operation of the tunnel 2. Thus, when the folding or unfolding operation of the boarding tunnel 2 is performed, The belt drum 12 (14) fixed to the second tunnel (5) in the process of folding or unfolding the second tunnel (5) with the third tunnel (6) even if no tensile force is applied to the second tunnel The flat belts 11 and 13 are automatically restored to their original positions by moving the flat belts 11 and 13 in the forward and backward directions, The moving speed of the second tunnel 5 is half of the moving speed of the third tunnel 6 due to the structure of turning around.

As described above, the interlocking type expansion and contraction operation of the boarding tunnel 2 by the folding unit 10a and the spreading unit 10b can be regarded as being substantially the same as the conventional method. However, in the case of the present invention, Flat belts 11 and 13 for embedding an iron core or a steel wire 21 inside the belt 20 and exhibiting excellent tensile strength and a belt drum 12 for advancing the flat belts 11 and 13 in the form of a conveyor belt The folding unit 10a and the spreading unit 10b can be formed of the wire rope 14 so as to have a more smooth and flexible surface than the wire rope, It is possible to silently and smoothly perform the stretching and contracting operation of the boarding tunnel 2 by using the flat belts 11 and 13 in which the stuttering is hardly generated and at the same time to improve the durability and service life of the equalizer 10 Provides differentiated benefits.

In particular, unlike conventional wire ropes, there is no need to apply anti-corrosive oil to the surfaces of the flat belts 11 and 13, so that the working period required for maintenance of the equalizer 10 can be maximized Of course, in the course of folding and unfolding the boarding tunnel 2, the phenomenon that the decorative carpet laid on the bottom surface 9 of the passage 3 of the third tunnel 6 is stained with oil can also be originally cut off, 3 unnecessary cleaning work for the passage bottom surface 9 of the tunnel 6 can be eliminated, and the cost required for normal operation of the boarding school 1 can be greatly reduced.

The folding unit 10a and the spreading unit 10b are installed to form a series of belt conveyor lines on the left and right sides of the lower surface of the boarding tunnel 2 while the second pulley function of the conventional equalizer The second belt drum 14 to be carried is also installed in the right posture in the horizontal direction on the opening 8a of the bottom surface 8 of the second tunnel 5, It is possible to quickly and easily perform the installation work of the equalizer 10 and prevent the action of the torsional load on the bracket or the rotation shaft of the second belt drum 14 and the occurrence of cracks or the like, The durability and the service life can be more sufficiently secured.

In addition, when the tension drum 18 is additionally provided, an appropriate tension is applied to the first flat belt 11 whose length is relatively longer than that of the second flat belt 13, The first flat belt 11 extending from the inlet side of the first tunnel 4 to the outlet side of the second tunnel 5 can be suppressed more reliably It is possible to prevent the tunnel 7 from being brought into contact with the bottom surfaces 7 and 8 of the tunnels 4 and 5 so that the expansion and contraction of the tunnel 2 can be performed more smoothly and smoothly, Durability and service life can be extended to a semi-permanent level.

Particularly when the tension drum 18 is capable of resiliently pressing the first flat belt 11 with the coil spring 27 interposed therebetween, Not only tensile deformation of the tunnel 2 due to shrinking deformation at the time of use, but also tensile deformation at the time of long-term use are adequately buffered to maintain a constant level of tension at all times. It is possible to provide an optimum equalizer 10 that can more accurately and stably perform the stretching operation of the boarding tunnel 2 through the buffering.
