Abstract
A lower-mounting-type escalator step tread front demarcation belongs to the field of making of escalators. The existing structure is fixed with a pedal beam by a bolt from the above position, and is easy to be corroded or loosen by impact. The lower-mounting-type escalator step tread front demarcation comprises a strip demarcation body, and the upper surface of the demarcation body is provided with a plurality of tooth tips which are vertical to the length direction of the demarcation body and are integrally formed; the lower-mounting-type escalator step tread front demarcation is characterized in that the tooth tips comprise tooth tip ends positioned at the front part and tooth pieces positioned at the rear part and having the thickness smaller than that of the tooth tip ends, the front ends of two adjacent tooth tips are both arranged in a same plane in a dislocation manner, wherein the front end of one tooth tip thereof extends out of the demarcation body, and the lower surface of the demarcation body is provided with blind holes; and the lower-mounting-type escalator step tread front demarcation has the advantages that: the mounting on the upper surface is changed into the mounting on the lower surface, thus overcoming the defect that sewage or liquid corrodes the staircase by a bolt hole, guaranteeing safe and stable staircase operation, shortening the length of the tooth tip ends, reducing the possibility of loosening due to impact of a comb plate, having convenient mounting and accurate positioning of the front demarcation after the tooth pieces are positioned, and easy connection with a pedal, and being beautiful and firm.
Description
[technical field]
The utility model relates to a kind of preceding demarcation of pedal that is installed in escalator step pedal and kickplate intersection, belongs to escalator and makes the field.
[background technology]
Large-scale places such as airport, museum, market escalator is installed usually, it comprises and is interconnected to form endless chain on-cycle plural number joint corrosion-resistant steel step.Every joint step is formed by pedal assembly, kickplate assembly and one group of spider that has main wheel axle bed and jockey pulley axle bed of carrying passenger.Prompt passengers is installed on the pedal tramples the safety in zone and delimit, with the installation site be divided into preceding demarcation, delimit the back and about side delimit.In the prior art, preceding demarcation is installed in the front end of pedal assembly, and it is provided with and pedal convex tendon tip surface in the same way for the elongate body of plastic material and upper surface, and elongate body rear end, tip surface dock with the pedal convex tendon.During installation, penetrate to being positioned at the preceding corrosion-resistant steel pedal crossbeam internal fixation of delimiting the below by the mounting hole of screw from the elongate body upper surface.The preceding demarcation of this structure, mounting hole and screw head all are exposed to the one side that the passenger tramples, liquid that the passenger overturns accidentally in the use or the sewage in the cleaning course can corrode the preceding demarcation activity of screw order or come off, also can enter into the pedal below along screw, further corrosion corrosion-resistant steel pedal crossbeam or other staircase parts influence staircase safe operation time and service life.In addition, because preceding demarcation has certain width and directly is installed with on the crossbeam at pedal rear portion, during therefore by the staircase fishback before demarcation can be subjected to the effect of power, rely on a little less than the screw bonded assembly firmness, be subject to the impulsive force of fishback and become flexible, even damage and split away off.
[utility model content]
The technical assignment of the technical problems to be solved in the utility model and proposition is to overcome the defective of delimiting before the existing pedal, provide a kind of mounting hole hidden, can better ensure the step safe operation, prolong step service life and be difficult for being delimited before the good following installing type escalator step pedal of fishback impact loosening, firmness.For this reason, the utility model adopts following technical scheme:
Delimit before the following installing type escalator step pedal, comprise strip shape demarcation body, delimiting the body upper surface is provided with a plurality of perpendicular to delimiting body length direction and integrated tip surface, it is characterized in that described tip surface comprise be positioned at anterior tip surface end and be positioned at the rear portion and thickness less than the gear piece of tip surface end, the front end of adjacent two tip surfaces all shifts to install in same plane, the front end of a tip surface in adjacent two tip surfaces extends the demarcation body, and described demarcation body lower surface is provided with blind hole.This changing of design the defective that mounting hole exposes in the prior art, pass the pedal crossbeam earlier from the below by screw and screw in the blind hole again, thereby preceding demarcation is fixed on the pedal front end.During installation, sway is delimited in location in the muscle groove of gear piece insertion pedal convex tendon before preventing, the tip surface end then is used for the muscle groove of shutoff pedal convex tendon, prevents that foreign material from entering, and groove is unimpeded between the adjacent convex tendon of guarantee step pedal, can pass through the staircase fishback smoothly.Therefore, the passenger overturns accidentally in the use liquid or the sewage in the cleaning course can't be stained with screw, nor can enter into the pedal below along screw, and further corrode corrosion-resistant steel pedal crossbeam or other staircase parts, have all obtained guarantee in staircase safe operation time and service life; Can make the short preceding demarcation of tip surface end length according to actual needs, when step was by fishback like this, the area of thrust surface of preceding demarcation obviously reduced, and were difficult for being impacted pitching, and increased fastness.The preceding demarcation if adopt and pedal color with distinct contrast still can be played and be pointed out safety to trample the effect in zone; If adopt with pedal near or identical colour, then pedal surface neatly, atresia, overall appearance degree height.
For the improving and replenishing of technique scheme, can increase following technical characterictic or its combination:
The front end of described tip surface is provided with lower surface and is domatic guide portion.Demarcation can waltz through the staircase fishback before the domatic assurance.
A tip surface at described demarcation body middle part is the location tip surface, and described location tip surface has the location gear piece that is thicker than other gear piece.The location gear piece inserts in the muscle groove of pedal convex tendon during installation, being generally the grafting of no gap cooperates, delimit sway before preventing, the thickness of other gear piece then can be slightly less than the width of pedal convex tendon muscle groove, allow the gap after the insertion, even the gear piece precision is not high when making like this, equally also can install very smoothly and accurate positioning.
The level of described tip surface end to length at the 2-30 millimeter.Length is more little, and area of thrust surface are more little during by fishback, and it is more little to be impacted the possibility that comes off, the firmness height.
Described demarcation body front side wall is provided with reinforced rib.Be used to support the demarcation body portion that tip surface is extended in setting forward, strengthen firmness.
The utility model is cashed the upper surface that technology is arranged and is installed as lower surface and installs and fixes, overcome dirt or liquid defective by attaching screw corrosion step, staircase safe operation time and service life have been guaranteed, and shortened tip surface end length, reduction is by the possibility of fishback impact loosening, delimit easy for installation, accurate positioning before the location gear piece order that is provided with especially, easy and pedal is connected and fixed, and attractive in appearance, firm.
