Automatic safety pedal device for construction elevator

Abstract

The invention discloses an automatic safety pedal device for a construction elevator. The automatic safety pedal device comprises a pedal body and an automatic opening device arranged on the side wallof the interior of the elevator, wherein the automatic opening device is in contact with the pedal body; the pedal body is fixed to the bottom of the elevator; the automatic opening device comprisesa fixing device, a baffle plate arm arranged on the fixing device, a sliding device and a spring; a fixed column connected to the spring is arranged on the fixing device; and the other end of the spring is fixed to the sliding device which is connected to the baffle plate arm. The automatic safety pedal device with the above structure for the construction elevator avoids the personnel injury caused by gaps in the material feeding and discharging process, ensures the smooth and safe transition of the entry and exit of a trolley, is detachable and recyclable, is suitable for different types of material elevators, and is convenient and fast to assemble and disassemble, easy to operate, conveniently to directly check and easy to daily maintain.

Description

technical field [0001] The invention relates to the technical field of auxiliary building facilities, in particular to an automatic safety pedal device for a construction hoist. Background technique [0002] Material elevators are widely used in the process of building construction. The purpose is to solve the vertical transportation of materials, but there is a certain distance between the material elevator and the unloading platform. When construction workers transport materials from the cage of the material elevator to the construction work surface, Usually the construction site temporarily uses wooden boards to cover the gap between the material elevator and the unloading platform as a pedal, or uses a simple steel plate as a temporary pedal. These are likely to cause temporary pedals or materials to fall from the gap, resulting in safety accidents, because Wooden boards or steel plates are not easy to fix when used as temporary pedals. During use, trolleys and construct...

[0002] Material elevators are widely used in the process of building construction. The purpose is to solve the vertical transportation of materials, but there is a certain distance between the material elevator and the unloading platform. When construction workers transport materials from the cage of the material elevator to the construction work surface, Usually the construction site temporarily uses wooden boards to cover the gap between the material elevator and the unloading platform as a pedal, or uses a simple steel plate as a temporary pedal. These are likely to cause temporary pedals or materials to fall from the gap, resulting in safety accidents, because Wooden boards or steel plates are not easy to fix when used as temporary pedals. During use, trolleys and construction workers are likely to move temporary pedals, causing materials and temporary pedals to fall, causing accidents. In addition, temporary pedals need to be removed when they are not in use. Time-consuming and labor-intensive, increasing labor costs and easily causing waste of materials

The existing automatic pedal is that the pedal is hinged on both sides of the bottom plate of the cage, the other end of the pedal is welded with two round steels, and two angle steels or channel steels are welded on the upper and lower sliding doors corresponding to the round steel of the pedal to form a joint with two joints. The track corresponding to the round steel, the round steel and the angle steel or channel steel form a snap ring, this structure is not easy to disassemble, and is not suitable for any type of material hoist
