Abstract

An external main control cabinet, comprising a resistor box (1) and a main control box (2). The resistor box is provided directly above the main control box; a C-shaped steel channel (3) used for separating the resistor box from the main control box is provided between the resistor box and the main control box to achieve heat insulation and heat dissipation; the front side of the main control box is provided with a double door (4); a portable maintenance window (5) is provided on the double door; a side of the main control box is provided with heat-dissipation ventilation openings (6). To overcome the problem of insufficient space for placing the control cabinet in an escalator truss machine room, the position of the resistor box may be adjusted according to an actual condition. The main control cabinet is full-featured, good in heat dissipation, simple in structure, and easy to install.

Description

External main control cabinet

Technical field:

The invention relates to an external main control cabinet, belonging to the technical field of elevators.

Background technique:

The control cabinet of the general escalator is placed in the upper machine room of the truss, including the power box, the main control box, the inverter box, the resistance box, etc. Due to the depth and length of the truss, the arrangement between the box and the box needs to be as compact as possible. In order to reduce the depth and length of the truss as much as possible, and reduce costs. However, with the improvement of the national standards for special equipment, the safety requirements are getting higher and higher, and the requirements of customers are increasing. It is bound to increase the number and types of electrical components in the control box, which leads to contradictions between the two. The control box came into being.

Summary of the invention:

The technical problem to be solved by the invention is that in order to overcome the shortage of the control cabinet in the escalator truss machine room, an external design with exquisite design, complete functions, beautiful appearance, better heat dissipation and waterproof effect, and favorable maintenance is provided. cabinet.

In view of the above technical problem, the external control cabinet involved in the present invention includes a resistance box and a main control box, and the resistance box is directly above the main control box, and an overhead resistor is disposed between the resistance box and the main control box. The box and the main control box are used to realize the heat-dissipating C-shaped channel steel. The main control box is provided with a double-opening door in front of the main control box, and the double-opening door is provided with a portable maintenance window, and the main control box side is provided with a heat dissipation vent.

Preferably, in order to improve the stability of the operation of each electronic component inside the main control cabinet, The emergency maintenance window is provided with an emergency stop button, a main power one-button cut-off button, a speed change switch, a fault reset button and a fault inquiry operation interface.

Preferably, in order to facilitate the lifting of the main control cabinet during installation, the C-shaped channel steel is provided with lifting holes for facilitating lifting of the main control cabinet.

Preferably, in order to improve the waterproof performance of the main control cabinet, the bottom of the main control box is provided with a mounting base for preventing rainwater from penetrating into the main control cabinet.

Preferably, in order to be able to adjust the placement position of the resistance box according to the on-site working environment, the resistance box and the main control box are movably connected.

Preferably, in order to improve the heat dissipation effect of the main control cabinet, a convection fan for exhausting heat is disposed at the heat dissipation vent.

Compared with the prior art, the invention has the advantages that: in order to overcome the shortage of the control cabinet in the escalator truss machine room, the position of the resistance box can be adjusted according to the site conditions, the function is complete, the heat dissipation is good, the structure is simple, and the installation is simple. Convenience.
