Description
Technical Field
[0001] The utility model belongs to the technical field of safety protection, and in particular relates to a gap safety protection device based on laser scanning. Background Art
[0002] At present, electric lifting platforms are often used in construction projects. The platform is raised and lowered to the required height mainly through an electric hydraulic system. It is used to lift workers or materials so that they can work at high places.
[0003] The existing electric lift platform is protected by guardrails to prevent workers from accidentally falling from heights, but there are no corresponding safety protection measures in the gap between it and the building. Workers need to be close to the building when performing high-altitude operations. Due to the large gaps in the guardrails, when workers accidentally step on the air and their legs enter the gap between the electric lift platform and the building, it is easy to cause injuries to the workers' legs, increasing the danger for the workers.
[0004] To this end, we provide a gap safety protection device based on laser scanning to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to provide a gap safety protection device based on laser scanning. Through the coordinated arrangement of the protection component and the protection component, the problem that the electric lifting platform in the prior art has no gap safety protection function and the workers are prone to step on air and get their legs stuck in the gap, causing injuries when performing aerial operations is solved.
[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0007] The utility model is a gap safety protection device based on laser scanning, comprising a lifting platform body, a protection component and a protection component, wherein a pedal is fixedly connected to the top of the lifting platform body, and a guardrail is fixedly connected to the top of the pedal;
[0008] The protection component is arranged at the bottom of the pedal, including a control box, a motor is fixedly connected to the left side of the inner cavity of the control box, a screw is fixedly connected to the right side of the output end of the motor, a threaded sleeve is threadedly connected to the surface of the screw, a connecting rod is fixedly connected to the top of the threaded sleeve, the top of the connecting rod passes through the inner cavity of the pedal and is fixedly connected to an extension plate, a limit plate is arranged in the inner cavity of the extension plate, a spring is fixedly connected to the right side of the limit plate, the left side of the limit plate passes through the outer side of the pedal and is fixedly connected to a top plate, and a laser ranging sensor is fixedly connected to the top of the left side of the pedal;
[0009] The protection component is arranged on the left side of the top of the pedal, including a movable shell, the left side of the movable shell is movably connected with a baffle, the front and rear sides of the pedal are fixedly connected with electric push rods, and the left side of the output end of the electric push rod is used for fixed connection with the movable shell.
[0010] The utility model is further configured that the front side and the rear side of the top of the movable shell are both provided with notches used in conjunction with the guardrail, and the inner wall of the movable shell is slidably connected to the pedal.
[0011] The utility model is further configured that the right side of the screw rod is movably connected to the inner wall of the control box through a bearing, and the top of the control box and the bottom of the pedal are both provided with movable openings used in conjunction with the connecting rod.
[0012] The utility model is further configured such that the front and rear sides of the right side of the pedal inner cavity are fixedly connected to a limiting tube, the inner cavity of the limiting tube is provided with a movable plate, the left side of the movable plate is fixedly connected to a pull rod, the left side of the pull rod passes through the limiting tube and is fixedly connected to the extension plate.
[0013] The utility model is further configured such that the front side and the rear side of the inner cavity of the control box are fixedly connected with slide rails, the surfaces of the slide rails are slidably connected with sliders, and the opposite sides of the two sliders are fixedly connected with the threaded sleeves.
[0014] The utility model is further configured that the shape of the connecting rod is L-shaped, and the right side of the spring is fixedly connected to the inner wall of the extension plate.

[0017] The utility model has the following beneficial effects:
[0018] 1. The utility model can scan and measure the distance between the pedal and the wall through the setting of the protective component. When the staff accidentally steps on the air, the legs block the signal of the laser distance sensor. At this time, the motor starts, and the motor cooperates with the screw to drive the threaded sleeve and the connecting rod to move. The connecting rod drives the extension plate to pop out quickly, and the gap between the pedal and the wall is blocked by the extension plate to prevent the staff's legs from being stuck in the gap and causing injuries, thereby increasing the safety of the use of the lifting platform body.
[0019] 2. The utility model sets a protective component. When the lifting platform body starts to be used, the electric push rod is started, and the electric push rod drives the movable shell to move to the right, so that the movable shell pulls the baffle. The baffle is expanded by squeezing the left side of the pedal and no longer blocks the laser ranging sensor. After the lifting platform body is used, the electric push rod is started again. The baffle is driven by the electric push rod and the movable shell to protect the laser ranging sensor to prevent the laser ranging sensor from being damaged.
[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
