A type of convertible barrier-free escalator

Abstract

This application provides a convertible barrier-free escalator, including an escalator body, a track inside the escalator body, several ordinary steps between the track and the escalator body, and several special steps connecting the ordinary steps. A lower lifting section is located at one end of the escalator body, and an upper lifting section is located at the other end. The lower and upper lifting sections are used to lift the special steps to achieve barrier-free switching. Through the lower and upper lifting sections and the special steps, this application allows the lower and upper lifting sections to independently lift multiple special steps, ensuring that the height of the multiple special steps remains consistent during inclined sections. This creates a wider platform between the tops of the multiple special steps to support wheelchairs, thus achieving barrier-free switching and facilitating use.

Description

Technical Field

[0001] This invention relates to the field of escalator technology, and more specifically, to a transferable barrier-free escalator. Background Technology

[0002] Escalators are generally inclined. When a pedestrian stands on one end of the escalator and moves automatically, he will be taken to the other end of the escalator. The steps will remain horizontal along the way. The escalator has handrails on both sides that move in sync with the steps for users to hold on to.

[0003] In the existing technology, the steps of most escalators are relatively narrow. Although they can meet the needs of normal pedestrians, they are difficult for wheelchair users to use, failing to meet the needs of barrier-free use and thus being unfavorable to users.

[0004] For example, Chinese utility model patent CN201520434860.6 discloses "A Barrier-Free Escalator," whose specification states that escalators, as inter-floor mobility devices, are commonly used in large shopping malls, office buildings, and other areas. Pedestrians can reduce the fatigue of walking upstairs and enjoy views of the mall while automatically moving between floors. However, for wheelchair users, escalators are difficult to use. They generally use vertical traction elevators or hydraulic elevators for safety reasons. However, using traction elevators or hydraulic elevators requires a certain waiting time and is relatively crowded, making them inconvenient and inefficient... The aforementioned patent can corroborate the shortcomings of the existing technology.

[0005] Therefore, we have made improvements to this and proposed a convertible barrier-free escalator. Summary of the Invention

[0006] The purpose of this invention is to address the problem that most existing escalators have narrow steps, which, while meeting the needs of normal pedestrians, are difficult for wheelchair users.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0008] Convertible accessible escalators are designed to address these issues.

[0009] The application is as follows:

[0010] The escalator includes a main body, a track inside the main body, several ordinary steps between the track and the main body, and several special steps connected between the ordinary steps. A lower lifting section is provided at one end of the main body, and an upper lifting section is provided at the other end of the main body. The lower and upper lifting sections are used to lift the special steps to achieve barrier-free switching.

[0011] As a preferred technical solution of this application, it also includes a drive system installed in the main body of the escalator, the drive system being used to drive several ordinary steps and multiple special steps to run in a cycle.

[0012] As a preferred technical solution of this application, a control cabinet is also installed inside the escalator body. The control cabinet is connected to the lower lifting section, the upper lifting section and the track. The control cabinet is used to control the lower lifting section, the upper lifting section and the track.

[0013] As a preferred technical solution of this application, the escalator body is provided with a handrail, and the handrail is provided with an up conversion button and a down conversion button.

[0014] As a preferred technical solution of this application, a gear set is provided inside the special step.

[0015] As a preferred technical solution of this application, both the lower lifting part and the upper lifting part are stepped lifting structures, and the stepped lifting structures are used to lift multiple special steps.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] In the scheme of this application:

[0018] 1. Through the setting of the lower lifting part, the upper lifting part and special steps, the lower lifting part and the upper lifting part can lift multiple special steps individually, so that the height of multiple special steps can be kept consistent when running in the inclined section, thereby forming a wider platform between the tops of multiple special steps to support wheelchairs, that is, to achieve barrier-free switching and facilitate use;

[0019] 2. Through the set disinfection warning mechanism, the support component and the disinfection warning component in the disinfection warning mechanism work together to disinfect the handrail, thereby reducing the situation where bacteria grow on the handrail and affect the health of passengers. The support component and the disinfection warning component also work together to form a warning structure, which can provide warnings during the maintenance of the escalator, thereby improving the functionality of the disinfection warning mechanism.

[0020] 3. When used for disinfection, the second support part works with the first support part to support the sliding part, and the height of the sliding part can be adjusted by moving the sliding part up and down after pulling the second support part, thereby meeting the needs of different types of handrails and facilitating use;

[0021] 4. When used as a warning function, the second support and the first support work together to support the disinfection unit and adjust the warning range, which is convenient for use;

[0022] 5. When used for disinfection, the disinfection unit can apply the disinfectant delivered by the conveyor unit to the handrail. When used for warning, the disinfection unit can unfold to form a warning line, thereby reminding pedestrians to stay away from the maintenance area, thus improving the functionality of the disinfection unit.

[0023] 6. When used for disinfection, the upper and lower clamps can be clamped onto the limiting strip under the action of springs, thereby fixing the position of the second support frame. When used for warning, the lower clamp can be adjusted to be perpendicular to the upper clamp, at which time the lower clamp can improve the stability of the upper clamp's support for the second support frame.

[0047] Example 1:

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment proposes a convertible barrier-free escalator, including an escalator body 4, a track 5 inside the escalator body 4, several ordinary steps 6 between the track 5 and the escalator body 4, and several special steps 7 connected between the ordinary steps 6. A lower lifting section 8 is provided at one end of the escalator body 4, and an upper lifting section 9 is provided at the other end of the escalator body 4. The lower lifting section 8 and the upper lifting section 9 are used to lift the special steps 7 to achieve barrier-free switching. The lower lifting section 8 and the upper lifting section 9 can lift the multiple special steps 7 individually, so that the height of the multiple special steps 7 can be kept consistent when running on the inclined section, thereby forming a wider platform between the tops of the multiple special steps 7 for supporting wheelchairs.

[0049] Example 2:

[0050] The following section provides a further description of the scheme in Example 1, focusing on its specific working method. See the description below for details:

[0051] like Figure 1 As shown, in a preferred embodiment, based on the above method, it further includes a drive system 10 disposed in the escalator body 4, the drive system 10 being used to drive a number of ordinary steps 6 and a number of special steps 7 to run in a cycle.

[0052] like Figure 1As shown, in a preferred embodiment, based on the above method, a control cabinet 11 is further installed inside the escalator body 4. The control cabinet 11 is connected to the lower lifting part 8, the upper lifting part 9 and the track 5. The control cabinet 11 is used to control the lower lifting part 8, the upper lifting part 9 and the track 5.

[0053] like Figure 1 As shown, in a preferred embodiment, based on the above method, the escalator body 4 is further provided with a handrail 14, and the handrail 14 is provided with an up switch button 12 and a down switch button 13, both of which are connected to the control cabinet 11.

[0054] like Figure 1 As shown, in a preferred embodiment, based on the above method, a gear set is further provided in the special step 7.

[0055] like Figure 1 As shown, in a preferred embodiment, based on the above method, both the lower lifting part 8 and the upper lifting part 9 are stepped lifting structures, which are used to lift multiple special steps 7.

[0056] like Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, it further includes a lifting mechanism 1, and a first adjusting mechanism 2 and a second adjusting mechanism 3 are respectively provided on both sides of the top of the lifting mechanism 1.

[0057] The lifting mechanism 1 includes a bearing part, on which a lifting part is provided; the first adjustment mechanism 2 includes a first driving part and a first transmission part provided on the lifting part, the first driving part being connected to the first transmission part; and the second adjustment mechanism 3 includes a second driving part and a second transmission part provided on the lifting part, the second driving part being connected to the second transmission part.

[0058] The lifting part in the lifting mechanism 1 can realize the lifting function. The first driving part in the first adjusting mechanism 2 can drive the first transmission part to move horizontally, so as to make corresponding position adjustments according to the position of the steps. The second driving part in the second adjusting mechanism 3 can drive the second transmission part to move horizontally, so as to make corresponding position adjustments according to the position of the steps, which is convenient for use.

[0059] like Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the supporting part further includes a housing 101, and grooves are provided on both sides of the top of the housing 101. The grooves allow the first motor 206 and the second motor 306 to avoid the housing 101, thereby reducing space.

[0060] like Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, support columns 104 are fixedly installed on both sides of the box 101, and the bottom of the box 101 is lower than the bottom of the support columns 104, so that the support columns 104 can support the box 101.

[0061] like Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the lifting part further includes two hydraulic lifting rods 102 fixedly installed on both sides of the top of the box 101. A base plate 103 is fixedly connected between the tops of the two hydraulic lifting rods 102. The base plate 103 can be driven to rise or fall by the cooperation of the two hydraulic lifting rods 102. When the base plate 103 rises, the lifting function can be realized.

[0062] like Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the first driving unit further includes a first motor 206 fixedly installed at the bottom of the base plate 103, and the position of the first motor 206 corresponds to the position of one of the grooves on the top of the housing 101. A first transmission gear 205 is fixedly connected to the output shaft of the first motor 206, and the first transmission gear 205 can be driven to rotate by the first motor 206.

[0063] like Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the first transmission part further includes a first slide groove 201 that passes through the top of the base plate 103. The top of the base plate 103 is also fixedly installed with two first rack pressure plates 202 located on both sides of the first slide groove 201. The first rack pressure plates 202 can limit the first driven rack 203, thereby preventing the first driven rack 203 from moving up and down and improving the stability of the first driven rack 203 moving horizontally.

[0064] like Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, a first driven rack 203 is slidably connected between the two first rack pressure plates 202 and the first slide groove 201. A first driving rack 204 located below the base plate 103 is fixedly connected to the bottom of the first driven rack 203. The first driving rack 204 meshes with the first transmission gear 205. The first motor 206 drives the first transmission gear 205 to rotate. The first driven rack 203 can be moved by the mutual cooperation of the first transmission gear 205 and the first driving rack 204.

[0065] like Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the second drive unit further includes a second motor 306 fixedly installed at the bottom of the base plate 103, and the position of the second motor 306 corresponds to the position of another groove on the top of the housing 101. A second transmission gear is fixedly connected to the output shaft of the second motor 306, and the second transmission gear can be driven to rotate by the second motor 306.

[0066] like Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the second transmission part further includes a second slide groove 301 that passes through the top of the base plate 103. The top of the base plate 103 is also fixedly installed with two second rack pressure plates 302 located on both sides of the second slide groove 301. The second rack pressure plates 302 can limit the second driven rack 304 and the third driven rack 305, thereby preventing the second driven rack 304 and the third driven rack 305 from moving up and down.

[0067] like Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, a second driven rack 304 and a third driven rack 305 are slidably connected between the two second rack pressure plates 302 and the second slide groove 301. A second driving rack 303 located below the base plate 103 is fixedly connected between the bottoms of the second driven rack 304 and the third driven rack 305. The second driving rack 303 meshes with the second transmission gear. The second motor 306 can drive the second transmission gear to rotate. The cooperation between the second transmission gear and the second driving rack 303 can drive the third driven rack 305 and the second driven rack 304 to move horizontally.

[0068] Specifically, when this convertible barrier-free escalator is in operation / use: when a passenger in a wheelchair is riding from the bottom to the top, they need to ride to the front of the escalator step, i.e., at the bottom conversion button 13, and press the bottom conversion button 13. At this time, the escalator will enter the barrier-free mode. Through the instructions set in the control cabinet 11, the escalator will run to the program-specified position. At the same time, the lower lifting section 8 will start and mesh with the gear set in the special step 7, and the upper lifting section 9 will also be ready.

[0069] When the special step 7 moves to the lower conversion button 13, the wheelchair is moved onto the special step 7, and the escalator will start to operate normally. Multiple special steps 7 will interact with the first driven rack 203, the third driven rack 305 and the second driven rack 304 in the lower lifting part 8 in turn, so that multiple special steps 7 are raised to the same horizontal position.

[0070] When the escalator reaches the upper arc section, multiple special steps 7 will interact with the first driven rack 203, the third driven rack 305, and the second driven rack 304 in the upper lifting section 9 in turn, causing each of the special steps 7 to return to its original position. After the wheelchair reaches a specific position in the upper horizontal section, the escalator will stop running. Pressing the upper conversion button 12 will reset the lower lifting section 8 and the upper lifting section 9 to their original positions, and the escalator will enter normal operation mode and stand by. Passengers can then leave the escalator.

[0071] Example 3:

[0072] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0073] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, in a preferred embodiment, based on the above method, it further includes two disinfection warning mechanisms 15 respectively placed at both ends of the escalator body 4;

[0074] The disinfection warning mechanism 15 includes a support component 151 and a disinfection warning component 152 disposed on the support component 151. The support component 151 includes a disinfectant tank 1511, and the disinfectant tank 1511 is provided with a first support part and a second support part.

[0075] The disinfection warning component 152 includes a sliding part that is height adjustable and is disposed between the first support part and the second support part. A disinfection part is disposed on the front of the sliding part, and a conveying part is disposed between the disinfection part and the disinfectant tank 1511.

[0076] The support component 151 and the disinfection warning component 152 in the disinfection warning mechanism 15 work together to disinfect the handrail 14, thereby reducing the risk of bacterial growth on the handrail 14 affecting the health of passengers. The support component 151 and the disinfection warning component 152 also work together to form a warning structure, which can provide warnings during the maintenance of the escalator, thereby improving the functionality of the disinfection warning mechanism 15.

[0077] The first support includes a third slide 1512 opened on one side of the top of the disinfectant tank 1511. Limiting strips 1514 are fixedly installed on the inner walls on both sides of the third slide 1512. A first support frame 1513 is fixedly installed in the third slide 1512. A liquid filling port is opened on one side of the top of the disinfectant tank 1511, through which disinfectant can be added into the disinfectant tank 1511.

[0078] The second support includes an upper clamping plate 1515 that is slidably connected to the third slide groove 1512 and located above the two limiting bars 1514. A second support frame 1516 is fixedly installed on the top of the upper clamping plate 1515. A handle 1517 is fixedly installed on the side of the second support frame 1516 away from the first support frame 1513. A first sub-Velcro is fixedly provided on the handle 1517. The handle 1517 is designed to facilitate the lifting of the second support frame 1516.

[0079] The upper clamping plate 1515 has a bottom groove 1518 at its bottom. A chamber 1519 is formed in the upper clamping plate 1515 above the bottom groove 1518. A connecting rod 15110 is slidably connected in the chamber 1519. The bottom end of the connecting rod 15110 passes through the chamber 1519 and the bottom groove 1518 and is fixedly connected to a lower clamping plate 15111 located below the upper clamping plate 1515. A spring is sleeved on the outer surface of the connecting rod 15110 in the chamber 1519. The sides of the upper clamping plate 1515 and the lower clamping plate 15111 that are close to each other are in contact with the limiting strip 1514. The force of the spring causes the upper clamping plate 1515 and the lower clamping plate 15111 to be clamped on the limiting strip 1514, thereby limiting the position of the second support frame 1516.

[0080] The sliding part includes a slide block 1521 slidably connected between the first support frame 1513 and the second support frame 1516. The contact surfaces of the first support frame 1513, the second support frame 1516 and the slide block 1521 are all rough. This arrangement can increase the friction between the slide block 1521 and the first support frame 1513 and the second support frame 1516, thereby improving the stability of the first support frame 1513 and the second support frame 1516 in clamping the slide block 1521. A slot 1522 is provided through the front of the slide block 1521. A screw 1523 is rotatably connected to the front of the slide block 1521 through a bearing. A retaining plate 1524 is fixedly sleeved on the outer surface of the screw 1523, and a nut 1528 is also threadedly connected to the outer surface of the screw 1523. A bolt is threadedly connected to the top of the slide block 1521, and the end of the bolt extends into the slot 1522.

[0081] The disinfection unit includes a roll 1525 sleeved on the outer surface of the screw 1523 and with its two ends in contact with the baffle 1524 and the nut 1528 respectively. A strip of cloth 1526 is wound around the outer surface of the roll 1525. One end of the strip of cloth 1526 is fixedly connected to the roll 1525, and the other end of the strip of cloth 1526 is fixedly connected to a female hook and loop fastener 1527. A second female hook and loop fastener is attached to the bottom of the female hook and loop fastener 1527. The second female hook and loop fastener is fixedly connected to the outer surface of the strip of cloth 1526. The second female hook and loop fastener and the female hook and loop fastener 1527 cooperate with each other to make the strip of cloth 1526 wound and fixed on the roll 1525.

[0082] The delivery unit includes a delivery pump installed in the disinfectant tank 1511. The outlet of the delivery pump is fixedly connected to a delivery hose 15210. The delivery hose 15210 can be bent to meet usage requirements. One end of the delivery hose 15210 extends out of the disinfectant tank 1511 and into the slide 1521. The end of the delivery hose 15210 located in the slide 1521 is fixedly connected to a rigid outlet pipe 1529. One end of the rigid outlet pipe 1529 extends from the front of the slide 1521, and several outlets are provided at the bottom of the slide 1521.

[0083] Specifically, when disinfecting this convertible accessible escalator during operation / use, please refer to the instructions. Figure 5 Pull the handle 1517 upwards and move it away from the first support frame 1513. Then push the cloth strip 1526 up and down and adjust its height according to the actual situation. After adjustment, push the second support frame 1516 towards the first support frame 1513 so that the second support frame 1516 cooperates with the first support frame 1513 to clamp and fix the slide seat 1521. Place the disinfection warning mechanism 15 on the handrail 14 so that the cloth strip 1526 contacts the handrail 14. The infusion pump delivers disinfectant to the rigid outlet tube 1529 through the delivery hose 15210. Then the disinfectant drips from the outlet onto the cloth strip 1526. The cloth strip 1526 applies the disinfectant to the handrail 14 to achieve disinfection.

[0084] When issuing a warning, first change the form of the disinfection warning mechanism 15 from... Figure 5 Switch to Figure 12 Pull the second support frame 1516 away from the first support frame 1513 to separate the upper clamping plate 1515 from the third slide groove 1512. Then rotate the lower clamping plate 15111 to insert it into the bottom groove 1518. After placing the slide block 1521 horizontally, put the slot 1522 onto the outer surface of the first support frame 1513 from the top. Then tighten the bolts, pull the female hook and loop fastener 1527 to separate it from the second male hook and loop fastener. Then pull the female hook and loop fastener 1527 to unfold the fabric strip 1526 and stick the female hook and loop fastener 1527 onto the first male hook and loop fastener on the handle 1517. At this time, the disinfection warning mechanism 15 is in the form of... Figure 12 As shown, this design is placed in the escalator maintenance area to warn pedestrians;

[0085] When it is necessary to switch the form of the disinfection warning device 15 back to normal... Figure 5At this time, pull the female hook and loop fastener 1527 to separate it from the first male hook and loop fastener. Then loosen the bolt and remove the slide block 1521 from the first support frame 1513. Wrap the fabric strip 1526 around the roll 1525 and stick the female hook and loop fastener 1527 to the second male hook and loop fastener. Pull down the lower clamping plate 15111 and rotate it so that it is parallel to the upper clamping plate 1515. Then place the upper clamping plate 1515 in the third slide groove 1512. The upper clamping plate 1515 and the lower clamping plate 15111 are respectively located above and below the limiting strip 1514. Place the slide block 1521 between the second support frame 1516 and the first support frame 1513. Push the second support frame 1516 so that the second support frame 1516 and the first support frame 1513 clamp and fix the slide block 1521.

[0086] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described herein. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present invention, as well as all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present invention.
