Abstract
The utility model discloses a bidirectional sliding moveable guard fence which is composed of fixed fences and movable fences. The utility model is characterized in that the fixed fences are composed of two groups, and each group of fixed fences is composed of a plurality of vault frames, an upper guide rod and a lower guide rod, wherein the vault frames are vertically fixed on a road surface, and the upper guide rod and the lower guide rod are respectively fixedly connected in a vertical way with the upper part and the lower part of two opposite straight rods; the guide rods are respectively provided with an inner gliding groove; the upper guide rods and the lower guide rods are respectively on the same horizontal plane and are parallel to the ground. The movable fences are arranged between the two groups of fixed fences, and the movable fences are composed of two groups; each group of movable fences is composed of an upper fence rod and a lower fence rod which are parallel to the ground, support rod fixedly connected with the upper fence rod and the lower fence rod, and a latch lock device arranged on the upper fence rod; the latch lock device is arranged on a wheel latch which is arranged in the inner gilding grooves of the guide rods, and can roll and move horizontally along the guide rods. The guard fence can be opened and closed conveniently at any time as required, and has the advantages of simple installation, convenient maintenance and low cost.
Description
The utility model relates to a kind of bi-directional push-pull movable rail, belongs to the operation technical field of traffic transportation.
The existing highway especially guardrail of speedway is isolated the general guardrail that adopts two kinds of patterns of broken belt, a kind ofly is fixing iron bar, and a kind of is the folding type movable guardrail.The former is welded with steel, and inserts and to be embedded in the underground sleeve pipe, in the time of need opening this isolation strip as emergency episode, must it be dialled one by one with the long period and remove, also need reinstall afterwards, obviously unfavorable timely processing accident, evacuate vehicle, and can certain damage be arranged road pavement during installation and maintenance; And the latter can open and close its isolation strip at any time, but also exist cost higher for adopting the movable rail of bar linkage structure formula, and mechanical strength is lower, not the defective of easy-maintaining.
The purpose of this utility model is exactly the defective that will overcome above-mentioned guardrail, and a kind of bi-directional push-pull movable rail is provided, and makes it can open and close it as requested at any time and isolates broken belt, when having an accident, can in time evacuate vehicle, and installation and maintenance is simple.
For achieving the above object, bi-directional push-pull movable rail of the present utility model is made of fixed fence and portable fence, it is characterized in that, fixed fence constitutes by two groups, every group of fixed fence by a plurality of vertically be fixed on the road surface the vault framework with constitute with the vertical respectively affixed upper and lower guide peg in the upper and lower of its two relative straight-bar, each guide peg is respectively equipped with internal chute, and last guide peg and following guide peg are in respectively on the same horizontal plane, and parallel to the ground; Between two groups of fixed fences portable fence is housed, portable fence constitutes by two groups, every group of portable fence is by upper and lower railing parallel to the ground, the affixed support bar of going up lower rail, be placed in the buckling and locking device on the railing, scroll wheel that is placed on the lower rail and can moves along the road surface and the directive wheel that is installed on the upper and lower railing constitute, and directive wheel is installed between the guide peg internal chute, can do to roll and translational motion along guide peg.In addition, the described vault framework of this bi-directional push-pull movable rail can directly be fixed on the road surface with setscrew.
Adopt bi-directional push-pull movable rail of the present utility model, under the traffic normal condition, two groups of portable fences can stretch out from each corresponding fixed fence by the roller motion, and lock with buckling and locking device, and close the isolation broken belt, as have an accident in the time of need opening the isolation strip, buckling and locking device then opened, slip in the corresponding fixed fence by promoting portable fence, and open the isolation broken belt, reach the purpose that can open and close its isolation broken belt at any time reliably, and install simple, easy to maintenance, cost is also cheaper.
Below in conjunction with embodiment the utility model is further described:
Fig. 1 is the assembling front view of the utility model under in off position
Fig. 2 is the assembling left view of the utility model under in off position
Fig. 3 is the assembling plan view of the utility model under in off position
Referring to accompanying drawing, vault framework 1 can be fixed on the road surface 3 by setscrew 2, be provided with internal chute 7,8 with its straight-bar 4 vertical affixed upper and lower guide pegs 5,6, and play two effects simultaneously, the one, the railing of the fence part of fixing, the one, play guide effect by the motion that is installed in upper and lower railing 9,10 and is installed on 11, the 12 pairs of portable fences of directive wheel on the internal chute 7,8.Support bar 13 affixed upper and lower railings 9,10, the external part on last railing 9 is equipped with a buckling and locking device 14, and the scroll wheel 15 that can move along the road surface is housed on lower rail 10.When need are opened this isolation strip, open buckling and locking device, can promote easily in the portable fence retraction portable fence; When need are closed this isolation strip, can easily portable fence be pulled out in fixed fence, and lock with buckling and locking device.
Should be noted that moving of the buckling and locking device of bi-directional push-pull movable rail described in the utility model and portable fence all can adopt electronics or other automated methods to control, and the conversion of these methods all should drop in the protection domain of the present utility model.
