Abstract
The invention discloses an anti-clamping device for an escalator. A direct current servo motor, a connecting sleeve, a pressure detecting device and a filling block which are sequentially connected are arranged on the pedal bottom. Two chutes are arranged on the filling block, a screw stem which is fixedly arranged on the pedal bottom is arranged in each chute, two square nuts which are mutually connected in parallel are arranged on each screw stem, and a filling plate is arranged between a pedal and each square nut to be capable of leftwards and rightwards moving on the square nut. By adjusting the left and right position of the filling plate, a gap between the pedal and a skirt panel in the movement of the escalator is enabled to be maintained in 0.5-1mm. When an object is clamped between the pedal and the skirt panel, the change of pressure is detected by the pressure detecting device, and the operation of the escalator is stopped. By adopting the device, the personal and property safety of a passenger is obviously improved when the escalator operates. Even though the object is clamped, the object can also be conveniently taken out.
Description
Technical field
The present invention relates to a kind of escalator anti-pinch device, belong to the elevator field.
Background technology
Owing to have bigger gap between the pedal of escalator and the apron plate, cause potential safety hazard easily.Although national standard has been made regulation to the gap between pedal and the apron plate, the gap standard between pedal and the apron plate is not more than 4mm, and the gap sum of two sides is not more than 7mm.Comprehensive this news report in several years, such gap is obviously excessive.
Respectively adorn one in the pedal both sides by plastics and dry lubricant preparation and the infill panel that pedal becomes with the apron plate, its shape and pedal are complementary.Infill panel keeps its position by spring or pull bar, and contacts with the apron plate in the total travel scope of escalator, has filled up the gap between moving staircase apron plate and the pedal both sides, and its safety guard-safeguard effect is tangible.Infill panel is a kind of dry friction with contacting of apron plate, and the teflon coating with the apron plate grinds off easily.
Safety brush anti-pinch device is made up of pedestal and hairbrush, and pedestal does not have sharp-pointed edge and can unload easily, and hairbrush is softness but also certain rigidity is arranged not only, does not hinder clothing, recovery automatically after passenger's shoes are run into hairbrush.But can not fundamentally solve the problem of anti-pinch.
The patent No. is 201010291156.1, and patent name is a kind of invention of escalator skirtboard anti-pinch device, discloses a kind of escalator skirtboard anti-pinch device, and it mainly is: when object is clamped, avoid injuring held object by backing down the apron plate.The installation requirement of apron plate own is just very high, so will damage the apron plate, causes unnecessary trouble; And using glass more and more as the escalator of apron plate in recent years, glass does not have elasticity, cannot be backed down.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the purpose of this invention is to provide a kind of escalator anti-pinch device of passenger's person and passenger safety when improving escalator operation.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions.
Bottom surface at pedal is equipped with infill panel.Shape and the pedal of infill panel are complementary, and infill panel comprises anti-biting bar and jut, and the length of anti-biting bar is identical with tread width.The skirtboard of escalator is made up of polylith apron plate, and this has just caused the impossible in-line of skirtboard of escalator, considers to make anti-biting bar contact to damage the apron plate with the apron plate that anti-biting bar stretches out the part of pedal just must be regulated.Have two road chutes thus on the jut, thread rod is fixedly mounted on the bottom surface of pedal, and infill panel is sleeved on the thread rod by chute, has been installed in parallel two square nuts on the thread rod, and infill panel can be along the chute sway.Gap between infill panel and the apron plate is 0.5-1mm, and this gap has guaranteed that personal safety can be protected.
Because pedal moves, when pedal moved to another piece apron plate next door from an apron plate, because the setting accuracy problem of apron plate and pedal, variation had taken place in the gap of pedal and apron plate, just needs to regulate the gap of pedal and apron plate.Use DC servo motor to be fixedly mounted on the bottom surface of pedal thus, DC servo motor is connected with control setup, the output shaft of DC servo motor is screw rod, infill panel is connected with connector bushing, the negative thread that matches with output shaft is arranged in the connector bushing, and DC servo motor is connected with connector bushing by motor shaft.Because DC servo motor can realize rotating, anti-biting bar just can be realized sway under the control of DC servo motor, guarantee that by the movement of anti-biting bar the gap between infill panel and the apron plate is 0.5-1mm.
Owing to still gapped between anti-biting bar and the apron plate, if tiny article fall in the gap, also may be clamped between pedal and the apron plate again.Between connector bushing and infill panel pressure-detecting device is installed, pressure-detecting device is connected with control setup.When object was clamped between pedal and the apron plate, pressure-detecting device detected pressure and changes, and stops the operation of escalator.After escalator was out of service, the control DC servo motor made the gap between anti-biting bar and the apron plate become big, takes out and is held article.
Further improve, the material of infill panel is nylon.Use nylon as the material of making infill panel, because that nylon has is in light weight, intensity is high, self-lubricating, can make the article that are held can not be subjected to further injury.
Beneficial effect.
1, the present invention has reduced the gap between pedal and the apron plate, makes clearance control between pedal and the apron plate at 0.5-1mm, passenger's the person and property safety when significantly having improved escalator operation.Even article are held, also can take out very easily.
2, the present invention is simple in structure, and is easy to assembly; Each structure is separate, and is easy to maintenance.
Description of drawings
Fig. 1 is the three-dimensional structure diagram of escalator anti-pinch device.
Fig. 2 is the infill panel structural representation.
Fig. 3 is the front view of escalator anti-pinch device.
Reference numeral is as follows:
