Description

Technical Field

[0001] This invention relates to the field of escalator technology, specifically to an anti-pinch device for escalator skirt panels. Background Technology

[0002] Escalators are a common type of vertical transportation equipment, widely used in shopping malls, subway stations, airports, and other public places. They are designed to facilitate the movement of people between different floors, especially in crowded areas. Escalators consist of a series of interconnected moving steps that circulate on a track via a drive system, allowing people to go up and down floors safely and quickly. Escalator skirts are an integral part of escalators, located at the edges, primarily for passenger safety and also for aesthetic purposes.

[0003] Patent CN213569072U discloses an anti-pinch device for an escalator skirt panel, including an skirt panel. One side surface of the skirt panel is provided with an anti-loosening pad, and an installation bolt passes through the surface of the anti-loosening pad. A brush holder is fixedly installed on the other side surface of the skirt panel. A limiting groove is formed inside the brush holder, and a fixing shell is engaged inside the limiting groove. A first brush is fixedly installed on the surface of the fixing shell, and a second brush is fixedly installed on the surface of the fixing shell below the first brush. An adjustment device is movably installed on the surface of the brush holder, and a central mechanism is movably installed on the surface of the second brush. The patent describes an anti-pinch device for escalator skirt panels, belonging to the field of anti-pinch devices. It can support the second brush from below and change the tilt angle of the second brush. The upper pressure plate and the support plate can clamp the second brush to prevent it from loosening and affecting the appearance. However, during the use of the above device, if a passenger deliberately puts their foot deep into the device, some uncontrollable accidents may still occur. At the same time, dust will accumulate on the brush bristles on the skirt panel over time, and the above device still requires cleaning staff to bend down and clean it manually, which is very troublesome. Therefore, an anti-pinch device for escalator skirt panels is proposed to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an anti-pinch device for escalator skirts, which addresses the shortcomings of the prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: an anti-pinch device for escalator skirts, including an mounting plate and a fixing plate, wherein the mounting plate and the fixing plate are fixedly connected by bolts and nuts, and an upper plate and a lower plate are fixedly connected to the front of the fixing plate, and brush bristles are fixedly connected to the front of both the upper plate and the lower plate.

[0006] During installation, the fixing plate is installed on the escalator mounting plate with bolts and nuts. Then, the fixing plate is removed, and the protective box is rotated at a certain angle so that the direction of the escalator's forward movement is aligned with the slope of the corresponding rotating protective box. After the protective box is rotated, the fixing plate is installed, and the bottom clamp of the fixing plate is inserted into the top of the protective box and the turntable to fix the two together.

[0007] A protective mechanism is provided at the front of the fixing plate, a cleaning mechanism is provided at the front of the fixing plate, and a pushing mechanism is provided on the surface of the protective mechanism;

[0008] The protective mechanism includes a protective box, a baffle is installed at the front of the protective box to prevent dust and debris from entering the protective box, a threaded rod is rotatably connected to the inner wall of the fixed plate, a guide rod is fixedly connected to the inner wall of the fixed plate, a turntable is threaded to the circumferential surface of the threaded rod, a fixed plate is installed on the top of the turntable, and multiple locking rods are fixedly connected to the bottom of the fixed plate.

[0009] By rotating the threaded rod with a tool, the threaded rod drives the turntable and the protective box to rotate. However, the protective box is limited by the guide rod and cannot rotate. Therefore, rotating the threaded rod can only move the turntable and the protective box forward, so that the front of the protective box moves between the two bristles. This allows someone riding the escalator to place their shoes against the bristles, and the shoes that move with the escalator will contact the inclined surface of the protective box, preventing the shoes from entering and thus preventing them from being trapped in the escalator, thereby improving the safety of the escalator.

[0010] Preferably, the circumferential surface of the lever contacts the inner wall of the top of the protective box, the circumferential surface of the guide rod contacts the inner wall of the protective box, and the circumferential surface of the turntable is rotatably connected to the inner wall of the protective box.

[0011] The rotation angle of the protective box can be adjusted arbitrarily to adapt to escalators moving in any direction. There is no need to install it in the opposite direction when installing an escalator with a fixed slope, which is very user-friendly.

[0012] Preferably, the protective box is located between the upper plate and the lower plate, with the upper plate located above the lower plate.

[0013] Preferably, the cleaning mechanism includes an upper sliding plate and a lower sliding plate. Multiple cleaning rods are fixedly connected to the side of the upper and lower sliding plates away from each other. An upper fixed rod and a lower fixed rod are fixedly connected to the side of the upper and lower plates close to each other, respectively. An upper slider and a lower slider are slidably connected to the surface of the upper fixed rod and the lower fixed rod, respectively. The upper fixed rod and the lower fixed rod are used to provide support for the upper slider and the lower slider.

[0014] Preferably, a support plate is fixedly connected to the top of the lower plate, and a sliding rod is fixedly connected to the top of the support plate. Two upper transmission plates and two lower transmission plates are rotatably connected to the sides of the upper and lower sliders away from each other, respectively.

[0015] Preferably, there are multiple upper and lower sliding plates, a spring is provided between two upper sliding plates, a spring is provided between two lower sliding plates, the side of the upper transmission plate away from the upper slider is rotatably connected to the inner wall of the upper sliding plate, and the side of the lower transmission plate away from the lower slider is rotatably connected to the inner wall of the lower sliding plate.

[0016] When workers need to clean the brush bristles, they stop the escalator and use their shoes to push the sliding rod. The sliding rod moves towards the mounting plate with the support of the support plate. The sliding rod pushes the lower and upper sliding blocks to separate through the inclined plane and rollers. The lower and upper sliding blocks then push the lower and upper sliding plates to move through the lower and upper transmission plates, respectively. The lower and upper sliding plates drive the cleaning rod to move. The cleaning rod moves through the brush bristles and cleans off the dust or debris on the surface of the brush bristles. It is very convenient and quick, without the need for workers to bend over or squat down to clean with cleaning tools.

[0017] Preferably, the rear inclined surface of the slide rod contacts the upper slider and the lower slider respectively, and rollers are rotatably connected to the top inner wall and the bottom inner wall of the slide rod. The rollers are used to reduce the friction between the slide rod and the upper slider and the lower slider, thereby reducing wear.

[0018] Preferably, the pushing mechanism includes an arc-shaped plate, a push rod, and a ball bearing. The arc-shaped plate is fixedly connected to the inner wall of the top of the lower slide plate, the push rod is slidably connected to the inner wall of the protective box, and the ball bearing is movably connected to the inner wall of the bottom of the push rod.

[0019] Preferably, the pushing mechanism further includes a guide plate and a limiting plate. The guide plate is fixedly connected to the top of the push rod, and the limiting plate is fixedly connected to the bottom of the guide plate. The top of the guide plate is provided with a downward slope from the middle to the sides and the rear, which is used to guide the dust falling on its top so that the dust slides off.

[0020] Dust from the brush bristles falls onto the top of the protective box, where a guide plate directs the dust, allowing it to slide off the inclined surface and preventing it from accumulating and affecting the cleaning effect.

[0021] Preferably, the surface of the ball contacts the upper surface of the arc plate, the bottom of the guide plate contacts the top of the protective box, and the limiting plate is slidably connected to the inner wall of the top of the protective box.

[0022] When the lower skateboard moves, it drives the curved plate to move. The curved plate pushes the ball bearings upward through the curved surface. The ball bearings drive the push rod upward, the push rod drives the guide plate upward, and the guide plate drives the limit plate upward. This causes the guide plate to move up and down and causes the dust on its top to slide off, improving the dust cleaning efficiency.

[0023] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0024] 1. This escalator skirt anti-pinch device allows passengers to place their shoes against the brush area while riding the escalator. The shoes, moving with the escalator, will contact the inclined surface of the protective box and be pushed away from the escalator skirt, preventing the shoes from being trapped and improving escalator safety. The rotation angle of the protective box can be adjusted by rotating it to adapt to escalators moving in any direction. It eliminates the need for reverse installation when installing escalators with a fixed inclined surface, making it very user-friendly.

[0025] 2. The escalator skirt anti-pinch device allows workers to stop the escalator when they need to clean the brush bristles. The worker then pushes the sliding rod with their shoes, which in turn moves the lower and upper sliding plates. The lower and upper sliding plates move the cleaning rod, which moves through the brush bristles and removes dust or debris from the surface. This eliminates the need for workers to bend over or squat down to clean with cleaning tools, making it very convenient and quick.

[0026] 3. The escalator skirt anti-pinch device has a guide plate on the top of the protective box that guides the dust, allowing the falling dust to slide off the inclined surface of the guide plate, preventing dust from accumulating on the protective box and affecting the dust cleaning effect. At the same time, the guide plate moves up and down, causing the dust on its top to slide off, improving the dust cleaning efficiency. When the guide plate moves up to its maximum distance, the limiting plate is still on the inner wall of the top of the protective box, so the limiting plate can block subsequent dust and prevent subsequent dust from entering between the bottom of the guide plate and the top of the protective box.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1-10 One embodiment of the present invention is: an anti-pinch device for escalator skirts, including a mounting plate 1 and a fixing plate 2. The mounting plate 1 and the fixing plate 2 are fixedly connected by bolts and nuts. An upper plate 3 and a lower plate 4 are fixedly connected to the front of the fixing plate 2. Brush bristles 8 are fixedly connected to the front of both the upper plate 3 and the lower plate 4.

[0040] A protective mechanism 5 is provided at the front of the fixed plate 2, a cleaning mechanism 6 is provided at the front of the fixed plate 2, and a pushing mechanism 7 is provided on the surface of the protective mechanism 5;

[0041] The protective mechanism 5 includes a protective box 51. A baffle 52 is installed at the front of the protective box 51 to prevent dust and debris from entering the protective box 51. A threaded rod 53 is rotatably connected to the inner wall of the fixed plate 2, and a guide rod 54 is fixedly connected to the inner wall of the fixed plate 2. A turntable 55 is threadedly connected to the circumferential surface of the threaded rod 53. A fixed plate 56 is installed on the top of the turntable 55, and multiple locking rods are fixedly connected to the bottom of the fixed plate 56. When passengers ride the escalator, they place their shoes against the bristles 8. The shoes that move with the escalator will come into contact with the baffle 52 on the protective box 51. Since the baffle 52 is tilted with the protective box 51, it can block the shoes and prevent them from being added to the escalator, thus improving the safety of the escalator.

[0042] The circumferential surface of the lever contacts the inner wall of the top of the protective box 51, the circumferential surface of the guide rod 54 contacts the inner wall of the protective box 51, and the circumferential surface of the turntable 55 is rotatably connected to the inner wall of the protective box 51.

[0043] The protective box 51 is located between the upper plate 3 and the lower plate 4, with the upper plate 3 located above the lower plate 4. By rotating the protective box 51, its rotation angle can be adjusted arbitrarily to adapt to escalators moving in any direction. It eliminates the need for reverse installation when installing escalators moving in the opposite direction due to the fixed-direction slope, which is very user-friendly.

[0044] Working principle: During installation, the fixing plate 2 is installed on the mounting plate 1 of the escalator using bolts and nuts. Then, the fixing plate 56 is removed, and the protective box 51 is rotated at a certain angle around the turntable 55, so that the front of the protective box 51, i.e., the side where the baffle 52 is installed, is inclined. Figure 10 As shown, the protective box 51 is tilted to the left, suitable for elevators moving from left to right. If the protective box 51 is tilted to the right, it is suitable for elevators moving from right to left. After the protective box 51 rotates, the fixing plate 56 is installed, and the bottom locking rod of the fixing plate 56 is inserted into the top of the protective box 51 and the turntable 55 to fix them together. Then, the threaded rod 53 is rotated by a tool. The threaded rod 53 drives the turntable 55 and the protective box 51 to rotate, but the protective box 51 is limited by the guide rod 54 and cannot rotate. Therefore, rotating the threaded rod 53 can only drive the turntable 55 and the protective box 51 to move forward. The front of the protective box 51 moves between the two bristles 8, allowing a person to place their shoes against the bristles 8 while riding the escalator. The shoes, which move with the escalator, will then come into contact with the baffle 52 on the protective box 51. Since the baffle 52 is tilted along with the protective box 51, it can block the shoes and prevent them from being caught in the escalator, thus improving the safety of the escalator. By rotating the protective box 51, its rotation angle can be adjusted arbitrarily to adapt to escalators moving in any direction. It eliminates the need for reverse installation when installing escalators moving in the opposite direction due to the fixed-direction slope, which is very user-friendly.

[0045] Please see Figures 1-10Based on the above embodiments, in another embodiment of the present invention, the cleaning mechanism 6 includes an upper sliding plate 61 and a lower sliding plate 62. Multiple cleaning rods 63 are fixedly connected to the sides of the upper sliding plate 61 and the lower sliding plate 62 away from each other. Upper fixed rods 65 and lower fixed rods 64 are fixedly connected to the sides of the upper plate 3 and the lower plate 4 close to each other, respectively. Upper sliders 611 and lower sliders 610 are slidably connected to the surfaces of the upper fixed rods 65 and the lower fixed rods 64, respectively. The upper fixed rods 65 and the lower fixed rods 64 provide support for the upper sliders 611 and the lower sliders 610. When a worker needs to clean the brush bristles 8, the escalator is stopped, and the worker pushes the sliding rod 67 with their shoes, thereby moving the lower sliding plate 62 and the upper sliding plate 61. The lower sliding plate 62 and the upper sliding plate 61 move the cleaning rods 63, which move within the brush bristles 8 and remove dust or debris from the surface of the brush bristles 8. This eliminates the need for workers to bend over or squat down to clean with cleaning tools, making it very convenient and quick.

[0046] A support plate 66 is fixedly connected to the top of the lower plate 4, and a slide rod 67 is fixedly connected to the top of the support plate 66. Two upper transmission plates 68 and two lower transmission plates 69 are rotatably connected to the sides of the upper slide block 611 and the lower slide block 610 away from each other.

[0047] Multiple upper slide plates 61 and lower slide plates 62 are provided. A spring is provided between two upper slide plates 61 and between two lower slide plates 62. The side of the upper transmission plate 68 away from the upper slider 611 is rotatably connected to the inner wall of the upper slide plate 61. The side of the lower transmission plate 69 away from the lower slider 610 is rotatably connected to the inner wall of the lower slide plate 62.

[0048] The rear inclined surface of the slide rod 67 contacts the upper slider 611 and the lower slider 610 respectively. Rollers are rotatably connected to the top inner wall and the bottom inner wall of the slide rod 67. The rollers are used to reduce the friction between the slide rod 67 and the upper slider 611 and the lower slider 610, thereby reducing wear.

[0049] The pushing mechanism 7 includes an arc plate 71, a push rod 72, and a ball bearing 73. The arc plate 71 is fixedly connected to the inner wall of the top of the slide plate 62, the push rod 72 is slidably connected to the inner wall of the protective box 51, and the ball bearing 73 is movably connected to the inner wall of the bottom of the push rod 72.

[0050] The pushing mechanism 7 also includes a guide plate 74 and a limiting plate 75. The guide plate 74 is fixedly connected to the top of the push rod 72, and the limiting plate 75 is fixedly connected to the bottom of the guide plate 74. The top of the guide plate 74 is provided with a downward slope from the middle to the sides and the rear, which is used to guide the dust falling on its top, so that the dust slides off. The guide plate 74 on the top of the protective box 51 will guide the dust, so that the falling dust slides off the slope of the guide plate 74, preventing the dust from accumulating on the protective box 51 and thus affecting the dust cleaning effect. When the protective box 51 rotates, there will also be a ball bearing 73 and a push rod 72 located on the top of the arc plate 71. The guide plate 74 and the limiting plate 75 are made of lightweight materials, and only a ball bearing 73 and a push rod 72 are sufficient to push the guide plate 74 and the limiting plate 75 upward.

[0051] The surface of the ball bearing 73 contacts the upper surface of the arc plate 71, the bottom of the guide plate 74 contacts the top of the protective box 51, and the limiting plate 75 is slidably connected to the inner wall of the top of the protective box 51. The guide plate 74 moves up and down and causes the dust on its top to slide off, improving the dust cleaning efficiency. At the same time, when the guide plate 74 moves up to the maximum distance, the limiting plate 75 is still located on the inner wall of the top of the protective box 51. Therefore, the limiting plate 75 can block subsequent dust and prevent subsequent dust from entering between the bottom of the guide plate 74 and the top of the protective box 51.

[0052] Working principle: When the worker needs to clean the brush bristles 8, the escalator is stopped. The worker pushes the slide bar 67 with their shoes. The slide bar 67 moves towards the mounting plate 1 with the support of the support plate 66. The slide bar 67 pushes the lower slide bar 610 and the upper slide bar 611 to separate through the inclined plane and rollers. The lower slide bar 610 and the upper slide bar 611 push the lower slide plate 62 and the upper slide plate 61 to move through the lower transmission plate 69 and the upper transmission plate 68 respectively. The lower slide plate 62 and the upper slide plate 61 drive the cleaning rod 63 to move. The cleaning rod 63 moves in the brush bristles 8 and cleans the dust or debris on the surface of the brush bristles 8. There is no need for the worker to bend over or squat down to clean with cleaning tools. It is very convenient and quick.

[0053] Dust from the upper brush bristles 8 falls onto the top of the protective box 51. The guide plate 74 on the top of the protective box 51 guides the dust, allowing it to slide off the inclined surface of the guide plate 74, preventing dust accumulation on the protective box 51 and thus affecting the cleaning effect. Simultaneously, when the lower slide plate 62 moves, it moves the curved plate 71. The curved plate 71 pushes the ball bearing 73 upwards via its curved surface. The ball bearing 73 moves the push rod 72 upwards, which in turn moves the guide plate 74 upwards. The guide plate 74 then moves the limiting plate 75 upwards, causing the guide plate 74 to move up and down. This causes the dust on top to slide off, improving the dust cleaning efficiency. At the same time, when the guide plate 74 moves up to its maximum distance, the limiting plate 75 is still on the inner wall of the top of the protective box 51. Therefore, the limiting plate 75 can block subsequent dust and prevent subsequent dust from entering between the bottom of the guide plate 74 and the top of the protective box 51. When the protective box 51 rotates, there will also be a ball bearing 73 and a push rod 72 on the top of the arc plate 71. Since the guide plate 74 and the limiting plate 75 are made of lightweight materials, only a ball bearing 73 and a push rod 72 are enough to push the guide plate 74 and the limiting plate 75 to move upward.

[0054] This invention provides an anti-pinch device for escalator skirt panels. Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of the invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention.
