Detailed Description
In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.
As shown in fig. 1, 2, 3 and 4, the utility model comprises a support and a transfer vehicle for transferring the support. The support is including two expansion brackets that link together, and every expansion bracket all includes flexible frame 1 and is located flexible frame 1 inside and with flexible frame 1 sliding connection's flexible inside casing 2. Two flexible inside casings 2 pass through crossbeam 3 to be connected, and crossbeam 3 all is connected through actuating mechanism with every flexible frame 1, can realize flexible frame 1 through the actuating mechanism drive and keep away from or be close to crossbeam 3, and then realize the expansion bracket and expand or pack up. At least one supporting mechanism 4 is arranged below each telescopic outer frame 1.
In this embodiment, the supporting mechanism 4 is a jack, specifically a manual press-type jack, a piston rod of the jack is fixedly connected to the telescopic outer frame 1, and the bottom of the jack is disposed on the ground. The user can operate the jack and realize flexible frame 1 lift, fall, and then realize the lift of whole support. In this embodiment, two supporting mechanisms 4 are disposed below each telescopic outer frame 1, and the two supporting mechanisms 4 are respectively located at two sides of the driving mechanism.
In this embodiment, flexible inside casing 2 and flexible frame 1 adopt current slider and spout complex sliding connection mode, and is further, be equipped with the slider on the flexible inside casing 2, be equipped with the spout on the flexible frame 1, the slider is located the spout, and the slider just can no longer slide when the slider slides to the spout end to avoid flexible inside casing 2 to deviate from flexible frame 1.
In this embodiment, the two telescopic inner frames 2 are fixedly connected to the cross beam 3.
In this embodiment, the driving mechanism is a hydraulic cylinder 5, a cylinder seat of the hydraulic cylinder 5 is connected with the telescopic outer frame 1 through a pin shaft, a piston rod of the hydraulic cylinder 5 is connected with the cross beam 3 through a pin shaft, and the hydraulic cylinder 5 is connected with a hydraulic pump. When the piston rod extends, the distance between the telescopic outer frame 1 and the cross beam 3 is increased, the telescopic frame tends to expand, when the piston rod retracts, the distance between the telescopic outer frame 1 and the cross beam 3 is reduced, the telescopic frame tends to be folded, the extending width of the telescopic frame is adjustable, and the telescopic frame can be adjusted according to different roadway sections. The extension and contraction of a piston rod of the hydraulic cylinder 5 are controlled by a switch connected with a hydraulic pump electromagnetic valve, and the circuit connection relationship between the switch and the hydraulic pump electromagnetic valve is the prior art.
As shown in fig. 4, the transfer vehicle adopts an existing automatic walking type lifting platform, the automatic walking type lifting platform comprises a mobile base 8, a lifting frame 7 and a lifting platform 6, and the lifting platform 6 is used for lifting a support.
As shown in fig. 5, the stent transfer steps are as follows: the transfer vehicle is moved to the position under the support, the lifting frame 7 is lifted, the lifting platform 6 supports the support, the jack is retracted, the lifting frame 7 is decompressed, the lifting frame 7 carries the support to fall down, and the hydraulic cylinder 5 is operated to retract the telescopic frame. The shortened support frame is passed through the bottom of the adjacent support frame still in the supporting state by using the transfer vehicle, and is separated from the current working position. After reaching a proper position, the telescopic frame is unfolded, the lifting frame 7 is lifted, the lifting platform 6 lifts the lifting support and contacts with the top plate of the roadway, the jack is lifted, the top plate is supported, the lifting frame 7 falls, the transfer vehicle is moved away, and a moving process is completed.
