Problems solved by technology

[0002] At railway and highway intersections, in order to ensure the safety of railway traffic, electric gates are generally used as crossing protection equipment, but most of the electric gates in the prior art provide guidance for the gates through guide rails, and the disadvantage in use is that the structure is complex , The service life is short, especially in the installation and construction at the intersection of railways and highways. It is necessary to apply for traffic control when installing the gate walking guide rail to excavate the road surface. The construction period is long, which seriously affects the normal traffic order
In addition, the installation of gate guide rails will increase the unevenness of the road surface, affecting the normal passage of passing vehicles and pedestrians, and there are potential traffic safety hazards

Embodiment

[0024] The use of the present invention is very convenient. As shown in the accompanying drawings, when a railroad crossing needs a gate to block the crossing, the gate starts to close under the electric drive of the gate drive device, and the four-link height adjustment mechanism automatically adjusts the walking casters height to maintain balance and adaptability. At this time, the tackle frame slides slowly on the lower side of the gate. When the positioning block on the gate contacts the tackle frame, the tackle frame will stop sliding relative to the gate. The middle gate of the fence is supported; when the gate needs to return to its original state and open to the intersection, under the electric drive of the gate drive device, the gate starts to recover, and when the trolley reaches the position of the gate drive device, it will be blocked and stop , until the gate is retracted into the door frame.

Abstract

The invention provides a trackless motor-driven door supported and guided through truckles and belongs to the motor-driven door. The trackless motor-driven door comprises a gantry, a door, a fixed truckle mechanism, a sliding truckle mechanism and a door driving device, wherein the lower end of the gantry is fixed with the ground through a base, and the top of the gantry is connected through a cross beam; the door driving device is arranged at the bottom of the gantry; the door is inserted into the gantry; the top of the door is connected with the cross beam in a sliding way through a pulley wheel, and the bottom of the door is connected with the door driving device; the fixed truckle mechanism is arranged at the bottom of the left end of the door; the middle of the bottom of the door is provided with a positioning block; and the sliding truckle mechanism is arranged between the fixed truckle mechanism and the positioning block and is connected with the bottom of the door in a slidingway. Compared with the prior art, the motor-driven door has the advantages of scientific design, easy processing, no need for paving a guide steel rail on a crossing, simple construction, convenient use, convenient transportation, safety, reliability and suitability for landform ground surfaces with various road junctions.
