Abstract
A railing machine, which can rise and fall steadily, relates to the improvement of a balancing unit on the existing railing machine. The balancing unit is arranged on the end of the spindle within the cover at the top of the railing machine cabinet, and is composed of a U-shaped mounting seat, a spring seat, an adjusting ring, and a torsion spring with opposite screwing direction, which is positioned between the spring seat and the adjusting ring. The mounting seat is fixed on the cabinet through a bearing, the spring seat and the mounting seat are fixed face to face and the adjusting ring can rotate along the spindle. In order to increase the adjusting force, two adjusting rings are positioned on the spindle, and a plurality of through holes is arranged on the radial periphery of the adjusting ring. For the torsion spring between each adjusting ring and the corresponding spring seat, an end is fixed on the spring seat, while the other end is hooked and hung on a through hole of the adjusting ring, so as to achieve the objectives of adjusting the force of the spring and making the railing rise and fall steadily by changing the positions or numbers of the hung through holes. The utility model is suitable for road and bridge roll stations as well as vehicle inspection stations.
Description
One, affiliated technical field
The utility model is that a kind of road, bridge charge station and some of being used for needs then the let pass Handrail machine in place of parking checking, belongs to electromechanical integrated product.
Two, background technology
At present, the road of vehicle, bridge charge station or inspection post generally all are provided with the sign that the signal vehicular traffic stops, lets pass, and this sign generally adopts Handrail machine.Handrail machine is by motor, power-transmitting part and block bar and form, and to block bar and lifting/falling balance in the process, at the uniform velocity, accurately in order to allow, so each Handrail machine all is provided with bascule.The bascule of each Handrail machine had two kinds of structures in the past: the one, and adopt three extension springs to come adjustment power; The 2nd, adopt a torsion spring to regulate, its defective is, the former will be with three extension springs, therefore it takes up room greatly, noise height during action, balance quality is poor, though the latter only uses a torsion spring, satisfy the requirement of compact conformation, but can only regulate constant equilibrant force, when length lengthening that blocks bar or shortening, will lose the function of adjustment power, strengthen the load of decelerator, the scope of application is restricted.
Three, summary of the invention
For the adjustable range that overcomes existing Handrail machine bascule is little, defective such as volume is big, and the scope of application is little, the utility model provides a kind of new Handrail machine, and the scope of the bascule adjustment of this Handrail machine is big, volume compact, effective, can adapt to different purposes, the needs of different occasions.
The technical scheme that its technical problem that solves the utility model adopts is: at the existing casing that comprises, case lid, motor, power drive mechanism and blocking on the Handrail machine of bar, bascule is located on the main shaft in the casing top cover, one end of this main shaft is connected with and blocks bar and power drive mechanism thereof, the other end of main shaft has U type mount pad by bearing fixing, respectively be fixed with a spring base on the two ends inwall of mount pad, being provided with two on the main shaft in mount pad can be with the adjustable ring of main shaft rotation, between each adjustable ring and corresponding spring base, be provided with the opposite torsion spring of rotation direction, the torsion spring that described rotation direction is opposite is respectively the rotation torsion spring of left-handed or dextrorotation, on the radial circumference of adjustable ring upper edge, be provided with a plurality of through holes, one end of torsion spring is fixed on the spring base, the other end is connected on certain through hole of adjustable ring, the position that connects through hole on the adjustable ring by regulating, change the size of its torsion, make and block bar and reach statokinetic purpose, if, the road junction is narrower, it is shorter to block bar, can take down a torsion spring from through hole, just can adapt to different purposes, the demand of different occasions.
The beneficial effects of the utility model are: the bascule of this barrier machine is directly arranged in an end of main shaft, and only use two torsion springs, simple in structure, volume is little, original position and use number because of torsion spring can change again, therefore good balance effect is easy to use, is fit to various roads, bridge charge station or inspection post and uses.
Four, description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the front view of structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the left view of Fig. 1.
Among the figure: 1. casing, 2. case lid 3. blocks bar, 4. main shaft,
5. left-handed spring, 6. adjustable ring, 7. dextrorotation spring, 8. spring base,
9. mount pad, 10. attachment screw, 11. block pole socket.
Five, the specific embodiment
With reference to accompanying drawing: in the case lid (2) on casing (1) top, be provided with main shaft (4), one end of main shaft (4) is connected with and blocks pole socket (11), interior being connected with by attachment screw or rivet (10) of this railing seat blocked bar (3), block pole socket (11) under the driving of main shaft (4), can make and block bar (3) and rotate together, lifting/falling of bar blocked in realization, stop or the purpose of the vehicle of letting pass to reach, the other end at main shaft (4) is fixed with U type mount pad (9), on two inwalls of mount pad (9), be fixed with spring base (8), be provided with two adjustable rings (6) that rotate synchronously with main shaft on the main shaft in mount pad (9), the radial circumference of this adjustable ring is provided with a plurality of through holes, be provided with the opposite torsion spring of rotation direction (5) or (7) between each adjustable ring (6) and corresponding spring base (8), an end of torsion spring is fixed on the spring base, and the other end colludes on certain through hole that is suspended to adjustable ring, by the position that regulating spring is hung through hole on the adjustable ring, realize that the balance of blocking bar rises and falls.
Claims (2)
1, a kind of Handrail machine, comprise that casing, case lid, motor, power pass with mechanism, railing, it is levied and is: be located on the main shaft (4) in casing (1) the top case lid (2), one end is connected with and comprises and block bar and power drive mechanism thereof, the other end is fixed with U type mount pad (9) by holding, on the inwall of the two ends of mount pad, respectively be fixed with a spring base (8), be provided with two adjustable rings (6) that can rotate with main shaft on the main shaft in mount pad, between each adjustable ring and corresponding spring base, be provided with the opposite torsion spring of rotation direction (7).
2, Handrail machine according to claim 1 is characterized in that: the torsion spring that described rotation direction is opposite is the rotation torsion spring of left-handed or dextrorotation; Described adjustable ring, its radial circumference is provided with a plurality of through holes.
