Description

Platform Screen Door Working Footplate The present invention relates to a platform screen door work platform used for trackside inspection and maintenance work on platform screen doors at railway stations. It allows for easy performance of work at various heights through height adjustment and prevents accidents by manufacturing the work platform close to the edge of the platform. Inspection and maintenance of platform screen doors at railway stations are usually carried out at night after the tracks are closed. When inspecting and maintaining track-side sensors, emergency door panic bars, and opening/closing handles of movable doors, the protrusion length of the platform edge is short, ranging from 0 to 30 cm. Consequently, workers must either wear safety harnesses and attach a safety hook to the platform screen door head box to perform track-side work, or place a long ladder on the tracks to carry out the work. However, inspection and maintenance work is only possible within the radius of the safety hook installed on the safety harness, and there are limitations on the scope of work even when using a ladder on the tracks. In existing work, although the height between the top of the sleepers and the platform is 1.3m or more, the length of the safety hook for preventing workers from falling is 1m, which limits the working radius available to the worker. It is also very dangerous when the protruding length of the platform stone is short, and even when working with a long ladder placed on the track, the working range is restricted, and there is the inconvenience of having to move and install it frequently. Consequently, proper inspection and maintenance are impossible due to the unstable posture, and there have been several fall accidents caused by not wearing safety harnesses, as well as problems such as reduced work efficiency.

The platform screen door work platform of the present invention is characterized by enabling easy performance of work at various heights through height adjustment and preventing accidents by manufacturing the work platform in close proximity to the platform edge. The present invention will be described below with reference to the attached drawings. FIG. 1 is a perspective view of the present invention, FIG. 2 is a front view of the present invention, and FIG. 3 is a side view of the present invention. Referring to the drawings, the platform screen door work platform (1) is characterized by comprising a pair of tracks (10) arranged parallel in the longitudinal direction, wherein the tracks (10) include a first track (11) located adjacent to the platform (20) and a second track (12) located facing the first track (10), and the main frame (100) having a plurality of columns installed in the height direction on the upper part of the first track (11), a guide shoe (200) installed on the upper part of the second track (12) and having auxiliary wheels (210) attached to move along the longitudinal direction of the second track (12), and a length adjustment bar (300) connecting the main frame (100) and the guide shoe (200). FIG. 4 is a detailed perspective view of the main frame of the present invention, and FIG. 5 is a drawing showing the main wheel of the present invention. Referring to FIG. 1 to 3, the main frame (100) is erected in the height direction with a plurality of columns on the upper part of the first track (11) located adjacent to the platform (20), and it is preferable that there are two columns. The two columns are positioned with a predetermined spacing. Between the two columns of the main frame (100), another column may be connected to fix the columns so that they do not twist. A main wheel (110) is attached to the bottom of the main frame (100) to enable movement along the length direction of the head of the first track (11). The main wheel (110) is an H-shaped wheel with a cross-section to prevent it from deviating from the first track (12), and is designed to roll while in contact with the side and top surfaces of the head of the first track (12), thereby facilitating movement so that a worker can perform work at a desired location using the main wheel (110). Additionally, a brake pedal (120) may be installed on the side of the main wheel (110) to enable braking of the main wheel (110) so that the worker does not move in a dif
