Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in figures 1 to 4, the bottom-lifting prop device comprises a base 1 and a prop oil cylinder 2, wherein the bottom of the base 1 is provided with a slot 10 for guiding a push rod 8 to pass through; one end of the supporting oil cylinder 2 is hinged with the base 1, a supporting oil cylinder 3 is arranged between the base 1 and the supporting oil cylinder 2, and two ends of the supporting oil cylinder 3 are respectively hinged with the cylinder body of the supporting oil cylinder 2 and the base 1. The above structure is an existing structure, so it is not described in detail here, and the specific scheme is as described in the patent application No. 201420080427.2, which has been filed by the applicant before.
The improvement is mainly as follows: one end of the base 1 is provided with a supporting wheel 4, a driving component 5 is arranged between the supporting wheel 4 and the base 1, and the supporting wheel 4 is contacted with a guide push rod 8 through the driving component 5 and can lift one end of the base 1.
When the device integrally moves forwards, the supporting wheel 4 is contacted with the guide push rod 8 through the driving component 5 and one end of the base 1 is lifted before the two deviation-adjusting oil cylinders arranged on the device extend; then, in the process that the two deviation-adjusting oil cylinders extend to push the hips to move forwards, one end of the base 1 is in contact with the guide push rod 8 through the supporting wheel 4 (rolling friction), and the other end of the base rubs against the floor, so that the resistance in the moving process can be effectively reduced. When supporting, the supporting wheel 4 retracts and is not contacted with the guiding push rod 8, and the whole bottom of the base 1 is contacted with the ground.
Further, as shown in fig. 1, the support wheels 4 are preferably provided at the front end of the base 1.
Further, the supporting wheel 4 comprises a supporting frame 40 and a wheel body 41, the supporting frame 40 is hinged with the base 1, and the wheel body 41 is rotatably connected with the supporting frame 40; the driving component 5 adopts a driving oil cylinder, and two ends of the driving oil cylinder are respectively hinged with the base 1 and the supporting frame 40.
When moving forward, the support frame 40 is rotated by extending the driving oil cylinder, the wheel body 41 gradually contacts with the guide push rod 8, and finally one end of the base 1 is jacked up. On the contrary, the driving oil cylinder retracts, so that the supporting frame 40 rotates reversely, and the wheel body 41 is not contacted with the guide push rod 8.
The structure can be realized by only arranging one driving oil cylinder, and the whole structure is simple.
Further, one end of the driving oil cylinder is fixed with a connecting seat 6 and is connected with the base 1 through the connecting seat 6, and the connecting seat 6 is provided with a corresponding hinge lug; the connecting seat 6 is fixedly connected with one end of the driving oil cylinder through a bolt. One end of the driving oil cylinder can be conveniently connected with the base 1 by arranging the connecting seat 6.
Further, two wheel bodies 41 are provided, and the two wheel bodies 41 are respectively located at two ends of the supporting frame 40.
Further, a support rod 7 is fixed on the base 1; the pipeline frame of each oil cylinder can be arranged on the supporting rod 7 through the supporting rod 7, and the arrangement of the pipeline is convenient.
Further, as shown in fig. 1, 5 and 6, the support rod 7 may be provided in various structures, preferably in the following structures: comprises a vertical rod 70 and a cross rod 71, wherein two ends of the vertical rod 70 are respectively fixedly connected with the cross rod 71 and the base 1; the two ends of the cross bar 71 are provided with stop bars 72.
The pipeline of each oil cylinder is erected on the cross bar 71, and the pipeline can be prevented from sliding off the cross bar 71 through the stop rods 72 at the two ends.
Further, although the pipeline can be prevented from slipping off by the stopper rod 72, there is still a possibility of slipping off; thus: the pressing plate 73 is arranged in parallel with the cross rod 71, and two ends of the pressing plate 73 are respectively connected with the two blocking rods 72 in a sliding manner; the two stop rods 72 are connected with fixing nuts 74 through threads.
When the pipeline clamping device is used, a pipeline is firstly erected on the cross rod 71, then two ends of the pressure plate 73 are respectively inserted into the stop rods 72 to form a frame shape, and then the fixing nuts 74 are screwed.
Further, rollers 75 are rotatably connected to the cross bar 71 and the pressing plate 73. By providing the roller 75, when the pipeline moves, the roller 75 can be driven to rotate, preventing dry (sliding) friction.
Although only the preferred embodiments of the present invention have been described in detail, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art, and all changes are encompassed in the scope of the present invention.
