Description

Ground rail

Technical field

The utility model relates to the ground rail that travels for dumper in a kind of factory floor.

Background technology

Mostly the dumper that transports raw material or workpiece in factory floor generally is to move on ground rail, the wheel of this dumper is to exist in pairs, each wheel comprises the inboard operation wheel and the position-limited wheel in the outside, and the axis of operation wheel and position-limited wheel is located along the same line.The track of prior art as shown in Figure 1 also is to exist in pairs, every track is an i iron 102 that is arranged in the ground groove 101, i iron 102 end faces and ground are contour, i iron 102 inboards (near a side of another root track) push against with groove 101 inside walls (near the sidewall of another root track), have slit 103 between i iron 102 outsides (away from a side of another root track) and groove 101 lateral walls (away from the sidewall of another root track); The operation of each wheel wheel is shelved on i iron 102 end faces, and position-limited wheel is contained in the slit 103 between i iron 102 outsides and groove 101 lateral walls.

There is following defective in the ground rail of above prior art: other vehicle such as small-sized go-cart etc. often need to cross ground rail, at this moment, if the gap width between the i iron of ground rail and the groove is excessive, the wheel that crosses the vehicle of ground rail is absorbed in the slit easily, and promptly to cross the ground rail difficulty big for wheel; If be snapped into the situation in slit and be provided with the width in slit very little in order to alleviate the vehicle wheel that crosses ground rail, can cause the bigger former truck of position-limited wheel thickness impassable on ground rail again.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of dumper current smoothly other vehicle that also can guarantee simultaneously on ground rail that can guarantee to cross the convenient ground rail smoothly of ground rail.

Technical solution of the present utility model is, a kind of ground rail is provided, it comprises two paired tracks, every track is first an interior i iron of groove that is contained in ground, the end face of first upper cross plate of first i iron is consistent with ground level, first i iron inboard with the groove inside wall near, have the slit between first i iron outside and the groove lateral wall, it also comprises at least one pair of slit closing device.

Each slit closing device comprises that one is positioned at the groove outside and is contained in pit and second i iron parallel with first i iron with the pit of groove connection with Duo Gen, be fixed with horizontal screw rod on the pit lateral wall, every second i iron is provided with the through hole that passes for screw rod, many second i iron slip cap side by side are combined on the screw rod, there is the gap between per two second adjacent i iron, the gap is much smaller than the slit between first i iron outside and the groove lateral wall, on the screw rod with the inside wall of the riser of every second i iron near the position be combined with fastening nut, be provided with elastic device between per two second adjacent i iron risers, second upper cross plate of the second the most inboard i iron is close to first upper cross plate of first i iron, and second upper cross plate of this second i iron is provided with arc limit or hypotenuse by two angles of first i iron.

Push against arc spring leaf between the riser of per two second adjacent i iron.

There is the gap in the equal in length of two transverse slats of every second i iron between second upper cross plate of per two second adjacent i iron.

Each slit closing device also comprises a fixed mount that is made of base plate and side plate, and the base plate of fixed mount and pit bottom surface are fixed, and the second all i iron is shelved on the base plate of fixed mount, and the side plate of fixed mount and pit lateral wall are fixed.

After adopting above structure, the utility model ground rail compared with prior art has the following advantages:

Dumper moves on ground rail, and its operation wheel is at the first i iron end face, in the slit of its position-limited wheel between first i iron outside and pit lateral wall.When dumper moves to closing device position, slit, position-limited wheel in the slit touches with the arc edge joint of the second the most inboard i iron, and dumper moves on, position-limited wheel can be passed the arc limit to the direction away from track, make some second i iron arranged side by side from inside to outside successively to direction motion away from first i iron, like this, will make that expose in the slit between first i iron that sheltered from by the second the most inboard i iron and the pit, thereby guarantee dumper trouble-free operation on ground rail.When dumper passes through the slit closing device fully, every second i iron can inwardly move under the promotion of spring leaf again, until pushing against on the fastening nut of every i iron inboard, at this moment, the second the most inboard i iron resets fully, promptly this second i iron and first i iron push against and first i iron and pit between the slit blocked fully, like this, the various vehicles that cross ground rail can not blocked by the slit, and it is convenient and swift to have guaranteed that various vehicles cross ground rail.

To sum up, first i iron of ground rail of the present utility model and the slit between the groove can be provided with big width, to stop the bigger dumper of position-limited wheel thickness impassable drawback on ground rail, simultaneously, because the existence of slit closing device, can when vehicle crosses ground rail, shelter from the slit between first i iron and the groove, guarantee the smooth and easy ground rail that crosses of vehicle.
