Abstract
Description
- The present invention relates to an extensible movable bridge assembly, comprising several cooperating parts for performing, in a tunnel being built, operations such as the loading of mines, laying of reinforcing ribs and nets and the like.
- The aim of the present invention, is to provide such an extensible movable bridge assembly which can be quickly and easily moved and installed.
- Within the scope of the above mentioned aim, a main object of the invention is to provide such an extensible movable bridge assembly which is very simple construction wise and very reliable in operation.
- According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by an extensible movable bridge assembly for use in building tunnels, characterized in that said bridge assembly comprises a bridge frame, coupled to a truck, said truck having a truck chassis on which two raising arms are pivoted, said raising arms bearing a counter-platform which, in turn, supports a platform provided with legs, oleodynamic piston means being moreover provided for raising said component parts in an independent way from one another.
- Further characteristics and advantages of the extensible movable bridge assembly according to the present invention, will become more apparent from the following detailed description of a preferred, though not exclusive, embodiment of the extensible movable bridge assembly according to the invention which is illustrated, by way of an indicative but not limitative example, in the accompanying drawings, where:
- Figure 1 is a side view illustrating the subject extensible movable bridge assembly mounted on a truck and in its fully closed and fully open positions;
- Figure 2 is a rear view of the extensible bridge assembly in its fully closed and fully open positions.
- With reference to the figures of the accompanying drawings, the extensible movable bridge assembly for making tunnels according to the invention, comprises a bridge frame, overally indicated at the
reference number 1, which is affixed, by four brackets 2, to the chassis of atruck 3. - The bridge frame essentially comprises four section members HE, (4), extending horizontally and welded, at respective end portions thereof, to two section members "HE", of like cross-section, so as to define a rectangular construction.
- At the corners of this rectangular construction there are are provided corresponding stabilizing
pistons 5 which are bolted to welded metal sheet box-like bodies 6. - To these section members HE (4), there is welded a central body 7, made of welded sheet metal and which is arranged at the cabin of the truck.
- This central body comprises four hinges for pivotably coupling raising arm members for raising a counter-platform which will be disclosed in a more detailed way hereinafter.
- There are moreover provided a first access ladder 8, two
guard walls second ladder 11 for accessing the platform. - The top raising arm, indicated at 12, comprises four C-shape section members welded in pairs and mutually spaced by a L-shape section member lattice 13.
- This top raising arm bears a hinge coupling portion for pivotably coupling the head portion of a raising
piston 14 which is also articulated to thebeams 4 of the frame. - The top arm, moreover, is articulated, at one end thereof, to the central body and, at the other end thereof, to a
central body 15 for supporting the above mentioned counter-platform. - As the
arm 12 is arranged at a lowered position, it will rest, through thelegs 16, on theframe 1. - With the above disclosed raising
arm 12 co-operates, at the bottom, a second raisingarm 17, also made of four C-shape section members, welded in pairs and mutually spaced by a L-shape section member lattice 13′. - This second raising arm, in turn, is pivoted, at one end thereof, to said central body 7 and, at the other end thereof, to the
central body 15 of thecounter-platform 18. - The above mentioned
central body 15 is made of a welded and suitably ribbed metal sheet, and bears the pivot hinges for the raisingarms - The counter-platform, in turn, comprises beams HE, (19), welded to the
central body 15 and bearinghorizontal rollers 20 on which a platform, overally indicated at 21, can slide. - There are moreover provided vertical-
axis rollers 22 for laterally restraining thesliding platform 21 on thecounter-platform 18. - The above platform, in particular, is driven by a
cylinder 23 which is respectively pivoted to said platform andcounter-platform 18. - The
platform 21 comprises moreoverguard walls 24, afloor 25, made of HE and IPE beams, a sheet metal covering, as well asabutment rollers 26 for saidbeams 19, which rollers are provided for sliding said platform along saidcounter-platform 18. - A leg bearing
frame 27 is moreover provided, made of square-cross-section tubular elements, in the inside of saidframe 27 there being providedtracks 28, made of C-shape section members, and bearing a panel on which slide thewheels 29 of leg orwing members 30. - These legs are arranged under the mentioned
floor 25 and are included in saidframe 27 which, on vertical sides thereof,supportsroller pairs 31 for restraining said legs. - Said legs, in particular are provided with
removable galleries 32 and comprise arespective piston 33 for driving said legs to perform extension and withdrawing movements. - A main feature of the invention is that in the subject extensible movable bridge assembly, the stabilizing elements, raising arms, platform and legs are driven by means of independent drives.
- From the above disclosure it should be apparent that the invention fully achieves the intended aim and objects.
- While the invention has been disclosed and illustrated with reference to a preferred embodiment thereof, it should be apparent that the disclosed embodiment is susceptible to several modifications and variations all of which will come within the spirit and scope of the appended claims.
