Description

Technical Field

[0001] The invention relates to the technical field of escalators or moving walkways, and in particular to a destructive escalator or moving walkway handrail entrance safety protection device and an installation structure thereof. Background Art

[0002] The safety protection device for the entrance of escalator or moving walkway handrail is an important protection device for escalator safety. In recent years, there have been frequent accidents of people being pinched or injured by handrail entrance in domestic public places. Major escalator manufacturers have also added safety protection devices for escalator handrail entrance. At present, the commonly used safety protection devices for handrail entrance are as follows: Figure 9 As shown in the figure, A1 is the entry rubber, A2 is the baffle, A3 is the connecting rod I, A4 is the fixing bracket, A5 is the connecting nut, A6 is the safety switch bracket, A7 is the safety switch, and A9 is the handrail I. When a foreign object enters the gap between the handrail I and the handrail buckle, it causes the entire entry rubber A1 to move leftward, thereby causing the underside of baffle A2 to move leftward and contact safety switch A7, thus achieving safety protection. However, this protective device has many problems in actual use: 1) The entry rubber is a single piece and is relatively hard. In actual use, when a foreign object, especially a hand, enters the gap, it can cause an injury before the protection is triggered due to the hardness of the entry rubber. 2) The entry rubber often requires a large impact force to deform the baffle and impact the safety switch, resulting in an insensitive protective device. This often causes injury by the time the protection is activated. 3) This structure generally only protects against fingers or foreign objects stuck in the gap directly below the entry of the handrail I, but does not provide sufficient protection against objects stuck in the gaps on either side of the handrail I. There are also some other protective devices in the prior art, but they are generally not sensitive and have large or uneven operating torques, which poses a major safety hazard to the domestic escalator market. Summary of the Invention

[0003] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a destructive escalator or moving walkway handrail entrance safety protection device and its installation structure, so as to solve the problems that the prior art protection devices are insensitive, have large or uneven operating torque, and cannot protect gaps in other directions of the handrail entrance.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A destructive escalator or moving walkway handrail entrance safety protection device comprises a vertically arranged fixed plate and two side baffles perpendicular to the fixed plate, the side baffles having a U-shaped cross-section, and the open sides of the two side baffles are located in the vertical plane and arranged facing each other, the rear end of the side baffles is connected to the fixed plate, and a gap is provided between the upper sides of the two side baffles; a contact switch is also provided on the upper side of one side baffle, and the touch end of the contact switch is arranged toward the direction of the other side baffle; an outer baffle is respectively provided at the front end of the two side baffles, and the opposite sides of the two outer baffles are rotatably connected to the two side baffles by a right-angle spring hinge. In the initial state, under the action of the right-angle spring hinge, the outer baffles are located in the vertical plane.

[0006] A guide bar is provided at the adjacent edges of the lower sides of the two side baffles, and the guide bar is arranged along the length direction of the side baffle, and there is a distance between its front end and the outer baffle; a guide rail is provided between the two guide bars, and the guide rail is clamped and fixed by the two guide bars, and the upper side of the guide rail is located below the upper side of the guide bar, so that a slide is formed between the two guide bars and the guide rail; a receiving groove is provided on the adjacent side of the two guide bars, and the receiving groove passes through the front end and upper side of the guide bar, so that the front opening of the slide is greater than the rear opening of the slide.

[0007] An extrusion slider is provided in the slideway, wherein the thickness of the front section of the extrusion slider is smaller than the thickness of the rear section thereof, and the width of the rear section of the extrusion slider is smaller than the width of the front section thereof, wherein the width of the rear section of the extrusion slider is smaller than the opening of the rear portion of the slideway, and the width of the front section of the extrusion slider is larger than the rear opening of the slideway and smaller than the front opening of the slideway; the front section of the slider is correspondingly located in the front portion of the slideway;

[0008] A push rod is provided on the extrusion slider, the rear end of the push rod is connected to the extrusion slider, and the front end thereof is in contact with the outer baffle; when the extrusion slider is pushed by the push rod and moves backward, it can interact with the handrail and move backward driven by the handrail.

[0009] During actual use, in the initial state, the contact end of the contact switch contacts the baseboard, the front end of the push rod abuts the outer baffle, and a gap exists between the squeeze slider and the handrail, allowing the escalator or moving walkway to operate normally. However, when a foreign object enters the gap between the outer baffle and the handrail, it will inevitably push the outer baffle to rotate toward the front end of the guide bar, thereby pushing the push rod to move toward its rear end. Since the squeeze slider is located in the receiving groove at the front of the slide, the push rod pushes the squeeze slider to slide toward the rear end of the slide. The rear section of the squeeze slider is smaller than the rear opening of the slide. Under the push of the push rod, the rear section of the squeeze slider slides into the rear of the slide. However, since the front section of the squeeze slider is wider than the rear opening of the slide, the rear section of the squeeze slider will expand the slide as it enters the rear end of the slide, thereby separating the guide rail from the guide bars on both sides, thereby driving the baffles on both sides to move away from each other, ultimately separating the contact switch on the side baffle from the baseboard, and causing the escalator or moving walkway to stop operating.

[0010] During actual application, the present invention only requires a very small force to push the push rod, which in turn pushes the extrusion slider to be in extrusion contact with the handrail, so that the elevator can be closed in time. The action torque can be controlled within a very small range, and the sensitivity is high, which can timely avoid damage to people or objects. At the same time, it can also protect all gaps between the wall panel, handrail and outer baffle, and can provide timely protection no matter which gap foreign objects enter from.

[0011] Preferably, a slide groove is opened on the upper side of the guide rail, and the slide groove is arranged along the length direction of the guide rail, and its two ends pass through the two ends of the guide rail; a slider is provided on the lower side of the extrusion slider, and the slider extends into the slide groove and is slidably connected to the guide rail, so that the extrusion slider can slide along the slide groove on the guide rail and ensure the sliding trajectory of the extrusion slider. At the same time, the slider extends into the slide groove and fills the slide groove, which can also prevent the extrusion slider from falling off the guide rail.

[0012] Preferably, two grooves are respectively provided on the upper surface of the extrusion slider, and the two grooves are spaced apart along the width direction of the extrusion slider, and the grooves extend from the front end to the rear end of the extrusion slider; a sliding block is provided in the groove, which can slide along the length direction of the groove, and one end of the sliding block is fixedly connected to the rear end of the push rod; a moving block is provided above the front section of the extrusion slider, and a connecting rod is provided between the moving block and the sliding block, the rear end of the connecting rod is rotatably connected to the moving block, and the front end of the connecting rod is rotatably connected to the sliding block, and under the action of external force, the push rod can push the connecting rod and the moving block to slide along the length direction of the groove through the sliding block; after the moving block moves backward, it can form extrusion with the handrail belt, and move backward driven by the handrail belt, while driving the extrusion slider to move backward. There can be multiple connection methods between the extrusion slider and the push rod. The present invention connects the push rod and the extrusion slider through a moving block and a sliding block. During actual use, the push rod pushes the sliding block to slide along the slot, and pushes the moving block to slide toward the rear end of the extrusion slider through the connecting rod, so that the moving block contacts the handrail. The handrail will squeeze the moving block downward and drive the moving block and the extrusion slider to slide toward the rear of the slide, thereby separating the guide bar and the guide track, disconnecting the connection between the contact switch and the wall guard plate, and allowing the escalator or moving walkway to be closed in time.

[0013] Preferably, the rear part of the front section of the extrusion slider protrudes upward to form a boss, the height of the boss is lower than the height of the rear section of the extrusion slider, and the boss and the front part of the front section of the extrusion slider are transitioned by an inclined surface, so that the front section and the rear section of the extrusion slider are stepped, and the moving block can slide onto the boss more easily through the inclined surface. At the same time, the rear section of the extrusion slider can prevent the moving block from slipping off the extrusion slider, so that the handrail can move with the moving block and the extrusion slider after squeezing the moving block.

[0014] Preferably, a plurality of clamping blocks are provided on both sides of the guide rail facing the guide bar, and a plurality of clamping holes corresponding to the clamping blocks are provided on the guide bar, and the guide rail is connected to the guide bar through the clamping blocks extending into the clamping holes.

[0015] Preferably, the rear end wall of the receiving groove is inclined so that the width of the receiving groove gradually decreases. This inclined surface makes it easier for the extrusion slider to enter the slideway and also makes it easier to separate the guide bar and the guide track, so as to close the escalator or moving walkway in time and prevent the device from causing damage to people or objects.

[0016] A mounting structure for a destructive escalator or moving walkway handrail entrance safety protection device comprises a vertically arranged wall guard plate and a handrail wrapped around its edge. The destructive escalator or moving walkway handrail entrance safety protection device according to the present invention is used, wherein the wall guard plate extends between the two side baffles from a gap on the upper side of the two side baffles, the handrail is wrapped around the wall guard plate and is located above a guide rail, and there is a gap between the handrail and the guide rail; notches are formed on the two outer baffles to match the wall guard plate and the handrail, so that there is a gap between the two outer baffles facing each other and the wall guard plate and the handrail; the touch end of the contact switch is in close contact with the wall guard plate and is conductive, and is connected to the escalator or moving walkway circuit; the height of the extrusion slider is greater than the minimum gap between the handrail and the guide rail; in an initial state, the touch end of the contact switch is in contact with the wall guard plate, the front end of the push rod is in contact with the outer baffle, and there is a gap between the extrusion slider and the handrail, and the escalator or moving walkway operates normally.

[0017] During actual use, in the initial state, the baseboard and handrail are installed between the baffles on both sides, the touch end of the contact switch is in contact with the baseboard, the front end of the push rod is in contact with the outer baffle, there is a gap between the extrusion slider and the handrail, and the escalator or moving walkway operates normally. When a foreign object enters the gap between the outer baffle and the handrail, it will inevitably push the outer baffle to rotate toward the front end of the guide strip, thereby pushing the push rod to move toward its rear end. Since the extrusion slider is located in the accommodating groove at the front of the slide, under the action of the push rod, the push rod pushes the extrusion slider to slide toward the rear end of the slide, wherein the rear section width of the extrusion slider is smaller than the opening at the rear of the slide. Under the push of the push rod, the rear section of the extrusion slider slides into the rear of the slide, but since the front section width of the extrusion slider is larger than the rear opening of the slide, the rear section of the extrusion slider will open the slide in the process of entering the rear of the slide, thereby separating the guide track from the guide strips on both sides of it, and then driving the baffles on both sides to move away from each other, and finally separating the contact switch on the side baffle from the baseboard, and the escalator or moving walkway stops running.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention forms a long, enclosed buffer space by symmetrically arranging two side baffles and guide strips on both sides of the handrail, as well as guide tracks arranged in conjunction with the guide strips. Through this series of structural designs, when foreign objects enter the gap around the handrail, even with the action of very small force, the escalator or moving walkway can be shut down in time, preventing the device from causing damage to people or objects.

[0020] 2. When the escalator or moving walkway is operating normally, the entire device of the present invention does not contact the handrail, and does not affect the normal operation of the escalator or moving walkway. In addition, the entire device is highly sensitive, and the required triggering torque is very small, avoiding the situation where the protection is not triggered in time and the injury has already occurred. At the same time, it can protect all gaps between the handrail and the outer baffle to prevent improper protection. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] 1. A destructive escalator or moving walkway handrail entrance safety protection device

[0033] The destructive escalator or moving walkway handrail entrance safety protection device includes a vertically mounted fixed plate 1 and two side baffles 2 perpendicular to the fixed plate. The side baffles have a U-shaped cross-section, with the open sides of the two side baffles located on the vertical plane and facing each other. The rear end of the side baffle is connected to the fixed plate, and a gap is formed between the upper sides of the two side baffles. A contact switch 3 is also provided on the upper side of one side baffle, with the contact end of the contact switch facing the direction of the other side baffle. An outer baffle 4 is provided at the front end of each side baffle. The two outer baffles are rotatably connected to the two side baffles on the opposite side via a right-angle spring hinge 5. In the initial state, the outer baffles are located on the vertical plane under the action of the right-angle spring hinge.

[0034] A guide bar 6 is provided at the adjacent lower edges of each side baffle. The guide bar runs along the length of the side baffle, with a gap between its front end and the outer baffle. The guide bar is fixedly connected to the underside of the side baffle. When the guide bar moves, the side baffle also moves. A guide rail 7 is provided between the two guide bars. The guide rail is clamped and fixed by the two guide bars, with the upper side of the guide rail located below the upper side of the guide bars, forming a slideway between the two guide bars and the guide rail. A receiving groove 8 is provided on each adjacent side of the two guide bars. The receiving groove extends through the front end and upper side of the guide bar, making the front opening of the slideway larger than the rear opening.

[0035] A squeeze slider 9 is provided within the slideway. The front section of the squeeze slider is thinner than the rear section, and the rear section is narrower than the front section. This allows the width of the front section of the squeeze slider to gradually decrease toward the rear section, making it easier for the squeeze slider to break the slideway, thereby separating the guide bar from the guide rail. The rear section of the squeeze slider is narrower than the rear opening of the slideway, while the front section is wider than the rear opening and narrower than the front opening. The front section of the slider is located within the front section of the slideway.

[0036] A push rod 10 is provided on the extrusion slider, the rear end of the push rod is connected to the extrusion slider, and the front end thereof is in contact with the outer baffle; when the extrusion slider is pushed by the push rod and moves backward, it can interact with the handrail and move backward driven by the handrail.

[0037] During actual use, in the initial state, the contact end of the contact switch contacts the baseboard, the front end of the push rod abuts the outer baffle, and a gap exists between the squeeze slider and the handrail, allowing the escalator or moving walkway to operate normally. However, when a foreign object enters the gap between the outer baffle and the handrail, it will inevitably push the outer baffle to rotate toward the front end of the guide bar, thereby pushing the push rod to move toward its rear end. Since the squeeze slider is located in the receiving groove at the front of the slide, the push rod pushes the squeeze slider to slide toward the rear end of the slide. The rear section of the squeeze slider is smaller than the rear opening of the slide. Under the push of the push rod, the rear section of the squeeze slider slides into the rear of the slide. However, since the front section of the squeeze slider is wider than the rear opening of the slide, the rear section of the squeeze slider will expand the slide as it enters the rear end of the slide, thereby separating the guide rail from the guide bars on both sides. The two guide bars then drive the baffles on both sides to move away from each other, ultimately separating the contact switch on the side baffle from the baseboard, causing the escalator or moving walkway to stop operating.

[0038] In one embodiment, a slide groove 11 is provided on the upper side of the guide rail, and the slide groove is arranged along the length direction of the guide rail, and its two ends pass through the two ends of the guide rail; a slider 12 is provided on the lower side of the extrusion slider, and the slider extends into the slide groove and is slidably connected to the guide rail, so that the extrusion slider can slide along the slide groove on the guide rail, and ensure the sliding trajectory of the extrusion slider, avoiding the sliding direction of the extrusion slider being inconsistent with the slide. At the same time, the slider extends into the slide groove and fills the slide groove, which can also prevent the extrusion slider from falling off the guide rail.

[0039] In one embodiment, two slots 13 are provided on the upper surface of the extrusion slider. The two slots are spaced apart along the width direction of the extrusion slider and extend from the front end to the rear end of the extrusion slider. A sliding block 14 is provided in the slot. The sliding block can slide along the length direction of the slot, and one end of the sliding block is fixedly connected to the rear end of the push rod. A moving block 15 is provided above the front section of the extrusion slider. A connecting rod is provided between the moving block and the sliding block. The rear end of the connecting rod is rotatably connected to the moving block, and the front end of the connecting rod is rotatably connected to the sliding block. Under the action of external force, the push rod can push the connecting rod and the moving block to slide along the length direction of the slot through the sliding block. After the moving block moves backward, it can form an extrusion with the handrail and move backward under the drive of the handrail, while driving the extrusion slider to move backward. The two ends of the moving block are raised to form a clamping head 16, and a bayonet 18 is provided at the rear end of the connecting rod to be clamped and connected to the clamping head of the moving block. The extrusion slider and the push rod can be connected in a variety of ways. For example, the extrusion slider can be directly connected to the push rod or connected to the push rod through other structures or devices. The present invention connects the push rod and the extrusion slider through a moving block and a sliding block. During actual use, the push rod pushes the sliding block to slide along the slot. The connecting rod pushes the moving block to slide toward the rear section of the extrusion slider, causing the moving block to contact the handrail. The handrail will then squeeze the moving block downward, driving the moving block and the extrusion slider to slide toward the rear of the slideway, thereby separating the guide bar and the guide track, disconnecting the contact switch from the baseboard, and causing the escalator or moving walkway to close in a timely manner. Among them, the rear part of the front section of the extrusion slider protrudes upward to form a boss 19, the height of the boss is lower than the height of the rear section of the extrusion slider, and the boss and the front part of the front section of the extrusion slider are transitioned by an inclined surface, and the front and rear parts of the front section of the extrusion slider form a step shape. Through the inclined surface, the moving block can more easily slide from the front part of the front section of the extrusion slider to the boss, and the position of the moving block can be raised so that it can contact the handrail belt, and under the limiting action of the rear section of the extrusion slider, the handrail belt continues to move with the moving block and the extrusion slider.

[0040] In one embodiment, a plurality of latching blocks 20 are provided on either side of the guide rail facing the guide bar, and the guide bar is provided with a plurality of latching holes 21 corresponding to the latching blocks. The guide rail is connected to the guide bar via the latching blocks extending into the latching holes. The guide rail and the guide bar can be connected by an interference fit, allowing the guide bar to be detachably connected to the guide rail, allowing the guide rail and the guide bar to be separated by squeezing a slider, thereby promptly shutting down the escalator or moving walkway.

[0041] In one embodiment, the rear end wall of the receiving groove is inclined, gradually reducing the width of the receiving groove. The inclined rear end wall of the receiving groove makes it easier for the extrusion slider to enter the slideway and also makes it easier to separate the guide bar from the guide track, allowing the escalator or moving walkway to be shut down in a timely manner to prevent damage to people or objects.

[0042] 2. Installation structure of a destructive escalator or moving walkway handrail entrance safety protection device

[0043] The mounting structure of the destructive escalator or moving walkway handrail entrance safety device includes a vertically mounted baseboard 22 and a handrail 23 extending around its edge. The baseboard extends between the two side panels through the gap on the upper side of the two side panels. The handrail is wound around the baseboard and positioned above the guide rails, with a gap between the handrail and the guide rails. Notches are provided on the two outer panels to accommodate the baseboard and handrail, creating a gap between the facing sides of the two outer panels and the baseboard and handrail. The contact switch's triggering end is in close contact with the baseboard, conducting electricity, and connected to the escalator or moving walkway's electrical circuit. The height of the extrusion slider is greater than the minimum gap between the handrail and the guide rails. In the initial state, the contact switch's triggering end is in contact with the baseboard, the front end of the push rod is in contact with the outer panel, and a gap is maintained between the extrusion slider and the handrail, allowing the escalator or moving walkway to operate normally.

[0044] During actual use, in the initial state, the baseboard and handrail are installed between the baffles on both sides, the touch end of the contact switch is in contact with the baseboard, the front end of the push rod is in contact with the outer baffle, there is a gap between the extrusion slider and the handrail, and the escalator or moving walkway operates normally. When a foreign object enters the gap between the outer baffle and the handrail, it will inevitably push the outer baffle to rotate toward the front end of the guide strip, thereby pushing the push rod to move toward its rear end. Since the extrusion slider is located in the accommodating groove at the front of the slide, under the action of the push rod, the push rod pushes the extrusion slider to slide toward the rear end of the slide, wherein the rear section width of the extrusion slider is smaller than the opening at the rear of the slide. Under the push of the push rod, the rear section of the extrusion slider slides into the rear of the slide, but since the front section width of the extrusion slider is larger than the rear opening of the slide, the rear section of the extrusion slider will open the slide in the process of entering the rear of the slide, thereby separating the guide track from the guide strips on both sides of it, and then driving the baffles on both sides to move away from each other, and finally separating the contact switch on the side baffle from the baseboard, and the escalator or moving walkway stops running.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the technical solutions. Those skilled in the art should understand that modifications or equivalent replacements of the technical solutions of the present invention that do not depart from the purpose and scope of the technical solutions of the present invention should be included in the scope of the claims of the present invention.
