Abstract

The invention discloses an easy-to-adjust escalator comb teeth protective device. The easy-to-adjust escalator comb teeth protective device comprises switch supports and switch touch plates. Each switch support is connected to one side of a comb teeth supporting plate and used for fixing a limit switch. The switch touch plates are connected to a comb teeth iron footboard. Self-set distance between a touch point of the front end of each switch touch plate and the corresponding limit switch is kept to be 2-3 cm. When a comb teeth plate is stuck by a foreign body, the comb teeth iron footboard is pushed to move, accordingly the switch touch plates are driven to move, and the touch points of the front ends of the switch touch plates touch the limit switches, so that the limit switches act to stop an escalator. The easy-to-adjust escalator comb teeth protective device has the advantages of being convenient to operate, maintain and adjust, the positions of the limit switches can be seen by opening a floor plate, and the adjustment of the limit switches is not affected even though outer decorative plates on the two sides of the escalator are already finished.

Description

The escalator comb protection device easily adjusted

Technical field

The present invention relates to the protection device of a kind of escalator comb, the escalator comb particularly to a kind of easy tune protects device.

Background technology

The protection device of escalator comb is after fishback snaps in foreign body, triggering limit switch action, making escalator out of service, thus protecting the safety of passenger-in-elevator.

Fig. 1 illustrates the structural representation of existing escalator comb protection device; as shown in Figure 1; the protection device of escalator comb is typically mounted at the centre position of comb gripper shoe 2; it is connected with support touch panel 4 by the roller 6 being arranged in comb gripper shoe 2; when fishback retreats, trigger limit switch 5. The shortcoming of this guard method is after escalator installs, owing to the decorating board of both sides has installed closing in use procedure, extremely inconvenient when the position of limit switch needs to finely tune, and brings very big trouble to debugging efforts.

Summary of the invention

The technical problem to be solved is to provide for a kind of debugging convenient escalator comb protection device.

In order to solve above technical problem, the invention provides the escalator comb of a kind of easy tune protection device, including:

Switch bracket, is connected to comb gripper shoe side, is used for fixing limit switch;

Switch touch panel, is connected on comb ferrum pedal, and the contact of switch touch panel front end keeps from the distance set with limit switch, and distance is 2��3cm;

When fishback has foreign body to block, promoting comb ferrum pedal to move, and then drive switch touch panel to move, limit switch is encountered in the contact of switch touch panel front end, makes limit switch action stop ladder.

Superior effect of the present invention is in that:

1) easy to operate, be easy to safeguard regulate;

2) open floor plates namely it can be seen that the position of limit switch, even if the balustrade exterior panelling of staircase both sides is complete, nor affect on the adjustment of limit switch;

3) installation and repairing is convenient, improves efficiency.

Detailed description of the invention

Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.

Embodiments of the invention are described in detail below in conjunction with Fig. 2.

Fig. 2 illustrates the structural representation of escalator comb of the present invention protection device. As in figure 2 it is shown, the invention provides the escalator comb of a kind of easy tune protection device, switch bracket 7 is bolted in the side of comb gripper shoe 2, and one end of switch bracket 7 is fixed with limit switch 5. The model of this limit switch 5 is 236-TR11.

Fig. 3 illustrates that the present invention switchs the structural representation of touch panel. As it is shown on figure 3, the rear end of described switch touch panel 8 is connected to the bottom of comb ferrum pedal 9, the contact 801 of switch touch panel 8 front end and limit switch 5 keep the distance of 2cm.

Described comb gripper shoe 2 is connected with the frame that spreads out by gripper shoe reinforcement 3.

The operation principle of the present invention: when fishback 1 finds that foreign body blocks; comb ferrum pedal 9 is promoted to be moved rearwards by; and then drive switch touch panel 8 to be moved rearwards by; the contact 801 then making switch touch panel 8 front end is moved back by, and the salient point of limit switch 5 is placed exactly in inner fovea part 802 under switch touch panel 8 front end, owing to switching the displacement of touch panel 8; promote the salient point of limit switch 5; making limit switch 5 action, escalator is out of service, the safety of protection passenger-in-elevator.

When needing the position of limit switch 5 is finely tuned, floor plates only need to be opened namely it can be seen that limit switch 5. Even if the balustrade exterior panelling of staircase both sides is complete, nor affect on the adjustment of limit switch 5. In use procedure, the practical application of the present invention is splendid.

The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations. All within the spirit and principles in the present invention, any amendment of making, equivalent replacements, improvement etc., should be included in protection scope of the present invention interior within.
