A horizontal pushing electric carriage device for side-opening doors

Abstract

The invention particularly relates to a horizontal push electric carriage device for a hinged door. The device comprises a rectangular frame, an internal door opening and closing mechanism, an external door opening and closing mechanism, a transmission mechanism and a control box. The internal door opening and closing mechanism and the external door opening and closing mechanism are mounted on the rectangular frame; an internal door is mounted on the internal door opening and closing mechanism; an external door is mounted on the external door opening and closing mechanism; and the control box controls the transmission mechanism to drive the internal door and the external door to be opened and closed in the horizontal direction. Through the adoption of the structure, the horizontal push electric carriage device occupies a small space, and the effective passing size after the doors are opened can be increased maximally.

Description

technical field [0001] The invention relates to a door opening device, in particular to a horizontal push electric carriage device for opening doors. Background technique [0002] At present, the common open door at the top of the shelter is an upward-turning hatch opening structure. The door opening device adopts a hydraulic cylinder or an electric push rod to open from the inside to the outside. It has the characteristics of high bearing capacity and convenient installation. [0003] But, there is following shortcoming in the device of this kind structure: [0004] 1. When hydraulic cylinders or electric push rods are used to open the side-by-side doors, because the installation space of the hydraulic rods and electric push rods is relatively large, the effective passage size after the door is opened is limited by the width of the shelter, and the effective space will be further reduced. The utilization rate is low. [0005] 2. When hydraulic cylinders are used, the cabi...

Problems solved by technology

[0004] 1. When hydraulic cylinders or electric push rods are used to open the side-by-side doors, because the installation space of the hydraulic rods and electric push rods is relatively large, the effective passage size after the door is opened is limited by the width of the shelter, and the effective space will be further reduced. low utilization

[0005] 2. When hydraulic cylinders are used, the cabin needs to be equipped with a separate hydraulic system, and there is a risk of oil leakage in the hydraulic system, which requires irregular inspection and maintenance. The skill level of maintenance personnel is relatively high, and the cost of equipment and maintenance costs higher average

Due to the higher requirements on the synchronization of the cylinder, it is necessary to use a higher-level electric push rod or a synchronous control system, and the cost is too high
