Abstract

The utility model relates to a pile type car stopper unit. In a columnar outer cylinder body, a columnar inner cylinder body which is provided with internal threads is engaged with a leading screw through screw threads, the leading screw is radially fixed by a bearing which is arranged on a supporting disk arranged on the inner wall of the outer cylinder body, and one end of the leading screw is connected with a motor which is in permanent connection with the inner surface of a bottom board of the outer cylinder body; when the size setting of the outer cylinder body, the inner cylinder body and the leading screw makes the motor drive the leading screw to rotate, the inner cylinder body can make vertically elevating motion on specified stopping and release positions. The pile type car stopper unit is underground arranged, the top of the pile type car stopper unit is parallel with the ground, during operation, a power supply is switched on, when the inner cylinder body is raised to a restricted height or the inner cylinder body is lowered to be parallel with the ground, a travel range switch cuts off the power supply of the motor, and thus the motor is stopped and locks the position of the inner cylinder body so as to complete the stop or release of vehicles.

Description

The pile supported stopblock unit

Affiliated technical field

The utility model has been set forth a kind of new pile supported stopblock unit, and this pile supported stopblock unit is used for the level crossing and stops that road vehicle collides the crossing protection hurdle; Keep off a car in toll station, parking area, the vehicle pass-through highway section of prescribing a time limit; Keep off a car in the open-air parking position, automobile burglar etc.

Background technology

At present, the employed stop buffer in each place all is structures that pin or baffle plate are arranged, and can not adapt to the demand of keeping off a car of different places.

Summary of the invention

In order to overcome the deficiency that existing stop buffer can not adapt to the demand of keeping off a car of different places, the utility model provides a kind of pile supported stopblock unit, it is underground that this pile supported stopblock unit can single or multiplely be installed in the place that need keep off a car as required, the top is equal with ground, when inner cylinder body is raised to constrain height from ground, can bear Vehicular impact effectively, stop vehicle pass-through.When inner cylinder body drops to height parallel to the ground, vehicle is normally current.

The technical scheme that the utility model technical solution problem is adopted is: in a cylindricality outer cylinder body; the tapped inner cylinder body of cylindricality is housed; one leading screw; one motor; one bearing; one step disk; the inboard wall of cylinder block both sides respectively have a slide groove outside; bottom dead point is equipped with travel switch on a slide groove; on inner cylinder body, connect two spacing swing arms that end; this spacing lifting up-and-down movement in slide groove that ends swing arm with inner cylinder body; realize that inner cylinder body is in the location of top dead point and bottom dead point and stop its rotation; described step disk is fixed on the inwall of outer cylinder body; this step disk is nested with a bearing; this bearing inner sleeve is enclosed within on the leading screw; be used to support fixedly leading screw; leading screw and tapped inner cylinder body pass through screw-threaded engagement; leading screw one end is connected with motor shaft; motor and outer cylinder body base plate inboard are fixedly linked; the driven by motor leading screw rotates together; drive the inner cylinder body lifting; when inner cylinder body is elevated to bottom dead center position; travel switch cuts off motor power control motor and shuts down; stopping and clearance vehicle realized in locking inner cylinder body position.Inner cylinder body top and cylinder body lid links to each other, and the outer cylinder body top is embedded with seal ring, is used for preventing that rainwater, silt etc. from entering influences the stop buffer normal operation in the cylinder body.

The beneficial effects of the utility model are: can adapt to the demand of keeping off a car of different places, and simple in structure, easy to use.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the vertical face physical structure figure of pile supported stopblock unit embodiment.
