Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 1, the construction platform vehicle for reinforcing a non-operational tunnel in this embodiment includes a rectangular frame, a working mechanism is disposed at an upper end of the frame, a vehicle body connecting portion is connected to a lower end of the frame, two axles for providing a power source are rotatably disposed at a lower end of the vehicle body connecting portion, a tire group is disposed on each axle, the tire group includes a pair of first tires and a pair of second tires, a distance between the first tires in the same tire group is short, a distance between the second tires is long, an outer diameter of each first tire is larger than an outer diameter of each second tire, outer diameters of the first tires and the second tires are adapted to arc transformation of a transverse section of the tunnel, and a plurality of telescopic cylinders are movably disposed on the frame.
The device carries out the operation through the supplementary manual work of operating device 2, the external diameter through being located inboard first tire 41 sets to the external diameter that is greater than the second tire 42 that is located the outside, make the arc transform of 4 external diameter adaptation tunnels of tire group, the contact area and the adaptation degree in tire group 4 and arc tunnel have been increased, make the driving steady, high driving efficiency, compare in the chinese patent of publication number CN208981038U only rely on arc tire and cambered surface contact, unsettled design of plane walking wheel, this design has been avoided, tire and tunnel area of contact are little, the problem of swift current smooth takes place easily, the inconvenient even possibility of taking place the incident of use has been reduced. When the platform truck operation, the automobile body need keep quiescent condition, because during the operation, certain external force will be applyed to the tunnel to the platform truck, the platform truck receives certain reaction force, in order to keep the automobile body static, accurate operation, flexible hydro-cylinder 52 through the activity setting, adjust the position of several flexible hydro-cylinder 52, when making flexible hydro-cylinder 52 extension conflict tunnel, form the balanced holding power to frame 1, further prevent that the vehicle from rocking or slipping, the atress slope when the operation has been avoided the platform truck, influence the problem of operation and personnel's safety.
Further, the four corners of frame 1, respectively fixedly connected with two connection pieces 5 that extend to the support outside on every corner, connection piece 5 on every corner is fixed mounting respectively in the upper end of frame 1 and the lower extreme of frame 1, and it has a driving arm 51 to rotate to be connected with between the connection piece 5 on every corner, and equal fixed mounting has telescopic cylinder 52 on each driving arm 51.
Please refer to fig. 2-3, the present application provides a preferred embodiment, four transmission arms 51 are rotatably disposed at four corners, and a telescopic cylinder 52 is disposed on the transmission arms 51, so that the platform truck drives the telescopic cylinder 52 to be disposed at a position attached to the side of the frame 1 when the platform truck does not need to be supported, and the telescopic cylinder 52 is accommodated in the transmission arms 51, when the platform truck needs to be supported, the transmission arms 51 rotate to drive the telescopic cylinder 52 to be away from the side of the frame 1, so that the telescopic cylinder 52 is conveniently supported by four points, and the platform truck provides a supporting force.
Further, a support portion 53 adapted to the arc-shaped tunnel is fixedly mounted on an output shaft of the telescopic cylinder 52, and an outer diameter of the support portion 53 is larger than that of the telescopic cylinder 52.
The device increases the lifting surface area, provides the holding power through setting up the supporting part 53 in adaptation arc tunnel, prevents to slide.
Further, a rubber pad is provided at the bottom end of the support portion 53.
The device is provided with the rubber pad through the bottom at supporting part 53, utilizes the physical characteristics of rubber pad to increase the frictional force of supporting part 53 and tunnel inner wall, further prevents skidding.
Further, extension platforms 31 are rotatably connected to both sides of the vehicle body connecting portion 3, so that the extension platforms 31 can be accommodated in the vehicle body connecting portion 3.
The device rotates through the both sides at vehicle body connecting portion 3 and connects extension platform 31, and it is rotatory at the during operation for extension platform 31 level expandes, has increased the area that the platform truck can be under construction or deposit the instrument, when need not to use, rotatory extension platform 31 makes the vertical both sides of accomodating to vehicle body connecting portion 3 of extension platform 31.
The working principle of the above embodiment is as follows:
when the device enters the arc tunnel, the first tire 41 with larger outer diameter contacts the part of the tunnel close to the arc top, the second tire 42 with the relatively small outer diameter is in contact with the position far away from the arc top of the tunnel, so that the tire group 4 is compared with the tires with the same size, the outer diameters of the two tires are matched with the arc transformation of the transverse tangent plane of the tunnel, the tires are completely contacted with the ground, and when the platform truck walks, the running is stable, the running efficiency is high, the problem that the device is easy to slide up and down due to partial contact with the ground of the tire when the arc tire is used independently in other designs is avoided, when the operation is needed, the driving arm 51 is started to drive the telescopic oil cylinder 52 to be far away from the side edge of the frame 1, thereby flexible hydro-cylinder 52 is four-point conflict tunnel inner wall, provides the holding power for the platform truck, further prevents that the platform truck atress from inclining when the operation, has avoided the platform truck to slide, incline, influences the problem of operation flow harm personnel's safety even.
