Abstract

The utility model discloses a variable separation guard rail, which comprises a wall body, a gear, a toothed rack, an electromagnet, a motor and a gear reducer; wherein, the electromagnet, the motor and the gear reducer are mounted on the wall body; the output shaft of the motor is integrated with the gear reducer; the output shaft of the gear reducer drives the gear, so that the wall body can fulfill meshing movement on the toothed rack. The utility model has advantages of simple structure, low cost, convenient manufacturing and installation, quick movement, flexible control, and increased traffic fluency for the lanes.

Description

Variable isolation guardrail

Technical field

The utility model relates to a kind of means of transportation, and the hurdle is expanded in particularly a kind of variable isolation.

Background technology

Continuous expansion along with developing of automobile industry and urban population, the construction of road traffic lags behind the demand of people to quick, safe and traffic easily all the time, this contradiction metropolis seems particularly evident, grade separation and speedway exist significantly " morning and evening tides " traffic behavior, promptly monolateral traffic congestion problem to the branch line of ambient radiation.How under the situation that does not change width, to increase the traffic capacity in track, still do not have effective method at present.

Summary of the invention

The purpose of this utility model provides a kind of variable isolation guardrail that can solve monolateral traffic congestion problem.

The purpose of this utility model realizes by following proposal:

A kind of variable isolation guardrail, comprise: body of wall, gear, tooth bar, electromagnet, motor and reductor, wherein, electromagnet, motor, reductor are installed on the body of wall, the output shaft and the reductor of motor link into an integrated entity, reductor go out shaft driven gear, make body of wall on tooth bar, do the grinding tooth motion.Described tooth bar fixes on the ground.

The utlity model has following advantage:

1. under the situation that does not change road width, increase the traffic capacity in track.

2. move rapidly, control flexibly.

3. simple in structure, be convenient to make and install.

Description of drawings

Fig. 1 is the scheme of installation of the variable isolation guardrail of the utility model;

Fig. 2 is the structural representation of the utility model tooth bar;

Fig. 3 is the structure sectional view of the variable isolation guardrail of the utility model.

The specific embodiment

The utility model will be further described below in conjunction with drawings and Examples:

The variable isolation guardrail of the utility model is made up of body of wall 1, gear 2, tooth bar 3, electromagnet 4, motor 5, reductor 6.During isolation guardrail work, be installed in electromagnet 4 energisings on the body of wall 1, electromagnetic actuation, output shaft and reductor 6 that motor 5 energisings are simultaneously rotated are connected as a single entity, again through reductor 6 go out shaft driven gear 2, allow body of wall 1 on tooth bar, do the grinding tooth motion, isolation guardrail is whole to be moved thereby make.When mobile protect fence moves when arriving assigned position, motor 5 outages, reductor 6 and gear 2 stop motions simultaneously, electromagnet 4 dead electricity are simultaneously inserted the purpose that reaches location and protecting against shock in the locating hole of tooth bar.Because the various combination of tooth bar is arranged, isolation guardrail can be done different motions according to the tooth bar track, or its combination, and shown in Figure 1 is exactly that guardrail is done swing and straight-line scheme of installation.

Claims

1. variable isolation guardrail, comprise: body of wall (1), gear (2), tooth bar (3), electromagnet (4), motor (5) and reductor (6), it is characterized in that, electromagnet (4), motor (5), reductor (6) are installed on the body of wall (1), the output shaft of motor (5) and reductor (6) link into an integrated entity, reductor (6) go out shaft driven gear (2), make body of wall (1) on tooth bar (3), do the grinding tooth motion.

2. variable isolation guardrail according to claim 1 is characterized in that, described tooth bar (3) fixes on the ground.
