Description
Technical Field
The utility model relates to a conveyer especially relates to a roll change dolly hydro-cylinder support.
Background
At present, the whole frame of the roll changing trolley of the original rolling line vertical rolling mill adopts a welding splicing mode, the trolley is driven by a hydraulic cylinder, when the hydraulic cylinder or the trolley needs to be overhauled and replaced, because a welding oil cylinder support is influenced by wheels at two ends, the inner space is very narrow and small, the auxiliary disassembly by tools such as a sledge hammer can not be used, and the overhauling difficulty and time are increased. Meanwhile, the oil cylinder support and the trolley frame are welded together, once the shaft hole is abraded, the trolley can only be completely lifted out for replacement, and the cost is high.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: to prior art not enough and defect, the utility model provides a roll change dolly hydro-cylinder support can reduce the intensity of labour and the time of overhauing by a wide margin, reduces equipment cost, improves work efficiency.
The technical scheme is as follows: the utility model discloses a roll change dolly hydro-cylinder support, including the dolly frame, its characterized in that: the trolley frame is provided with a plurality of threaded holes, the bottom of the trolley frame is provided with a groove structure, and the trolley frame is movably connected with the oil cylinder support; the top of the oil cylinder support is provided with a protruding structure corresponding to the groove structure, the protruding structure is embedded into the groove structure, the top of the oil cylinder support is provided with a plurality of threaded holes, the trolley frame is connected with the oil cylinder support through fixing bolts and matched nuts which penetrate the corresponding threaded holes, and the oil cylinder support is provided with a shaft hole.
Wherein, 4 corresponding threaded holes are formed at the joint of the trolley frame and the oil cylinder support.
The nut of the fixing bolt is positioned on one side of the trolley frame, and the nut matched with the fixing bolt is positioned on one side of the oil cylinder support.
Wherein, a gasket is arranged between the nut of the fixing bolt and the trolley frame.
And a gasket is arranged between the nut matched with the fixing bolt and the oil cylinder support.
Has the advantages that: compared with the prior art, the utility model has the following apparent advantage: the utility model discloses a detachable hydro-cylinder support, roll change dolly can directly be hung out, for overhauing the creation space, can reduce the intensity of labour and the time of overhauing by a wide margin. Meanwhile, when the shaft hole of the oil cylinder support is abraded, the oil cylinder support only needs to be detached and replaced independently, and the oil cylinder support is convenient and fast to use and low in cost. And the oil cylinder support and the trolley frame are prevented from relative displacement by adopting a concave-convex matching surface, so that the stability of the system is improved.

FIG. 2 is a schematic structural view of the welding cylinder support of the present invention;
in the figure, 1 is a trolley frame, 2 is an oil cylinder support, 3 is a groove structure, 4 is a bulge structure, 5 is an axle hole, 6 is a fixing bolt, and 7 is a nut.
Detailed Description
The technical solution of the present invention will be further described with reference to the accompanying drawings and the detailed description.
The utility model discloses a roll changing trolley oil cylinder support, which comprises a trolley frame 1, wherein the trolley frame 1 is provided with a plurality of threaded holes and the bottom of the trolley frame is provided with a groove structure 3, and the trolley frame 1 is movably connected with an oil cylinder support 2; the top of the oil cylinder support 2 is provided with a protruding structure 4 corresponding to the groove structure 3, the protruding structure 4 is embedded with the groove structure 3, the top of the oil cylinder support 2 is provided with a plurality of threaded holes, the trolley frame 1 is connected with the oil cylinder support 2 through a fixing bolt 6 penetrating through the corresponding threaded hole and a matched nut 7 of the trolley frame, and the oil cylinder support 2 is provided with a shaft hole 5. Wherein, 4 corresponding threaded holes are respectively arranged at the joint of the trolley frame 1 and the oil cylinder support 2. The nut of the fixing bolt 6 is positioned at one side of the trolley frame 1, and the nut 7 matched with the fixing bolt 6 is positioned at one side of the oil cylinder support 2. A gasket is arranged between the nut of the fixing bolt 6 and the trolley frame 1. A gasket is arranged between the nut 7 matched with the fixing bolt 6 and the oil cylinder support 2.
During the use, put into the groove structure 3 of dolly frame 1 with the protruding structure 4 of hydro-cylinder support 2, protruding structure 4 and groove structure 3 gomphosis, then carry out dolly frame 1 and hydro-cylinder support 2's connection through the fixing bolt 6 and its supporting nut 7 that pass corresponding screw hole.
In the prior art, the whole frame of the roll changing trolley adopts a welding and splicing mode, and the trolley frame and the oil cylinder support are welded together, so that the trolley frame cannot be disassembled and is difficult to overhaul. Meanwhile, once the shaft hole 5 is abraded, the trolley can only be completely lifted out for replacement, and the cost is high.
Use the utility model discloses a behind the change roll dolly hydro-cylinder support, when pneumatic cylinder or dolly overhaul the change, can demolish hydro-cylinder support 2's fixing bolt 6, the change roll dolly can directly be hung out, creates the space for the maintenance, then borrows appurtenance such as sledge hammer and demolishs, can reduce the intensity of labour and the time of overhauing by a wide margin. Meanwhile, when the shaft hole 5 of the oil cylinder support 2 is abraded, the oil cylinder support 2 only needs to be detached and replaced independently, and the oil cylinder support is convenient and fast to use.
