[0002] There is a certain gap between the car platform and the shaft. However, some platform elevators now have no car walls and doors, which may cause the passengers' bodies to get stuck in this gap. Therefore, in order to ensure the safety of the passengers, elevator manufacturers will install safety side guards at the platform edge (the edge of the car bottom) where the gap between the car and the shaft is the smallest. When the passengers' limbs press the safety side guard at this location, the elevator will not be able to run, thus preventing the occurrence of jams. The platform ladder safety side guard devices on the market are composed of materials such as compression springs, safety guards, switch pressure plate assemblies, and contact switch assemblies. The elastic deformation caused by the safety side guard pressing the compression spring is used to trigger the contact switch action, so that the safety circuit is blocked and the elevator is prevented from running, thereby avoiding the occurrence of jams. However, during the process of the safety side guard compressing the compression spring, the rigid friction between the compression spring guide sleeve and the guide bolt produces abnormal noise, affecting the comfort of the elevator.

[0003] In view of this, the present application aims to improve the existing safety ribs, achieve a silent effect, and enhance the comfort of elevator operation. Utility Model Content

[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the described embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] Unless otherwise defined, technical or scientific terms used herein shall have the ordinary meaning as understood by persons of ordinary skill in the art to which this application belongs. The terms "first," "second," and similar expressions used in this patent specification and claims do not denote any order, quantity, or importance, but are merely used to distinguish different components. Similarly, terms such as "a" or "an" do not denote a limitation of quantity, but rather denote the presence of at least one.

[0026] according to Figures 1 to 3 As shown, a new type of safety rib device for a platform elevator is shown in the example of the present invention. It is installed on the entrance side and left and right sides of the platform elevator. Each side includes an auxiliary bracket 14, a safety rib 11, a compression rubber 12 and a micro switch seat 13. Compared with the prior art, in the process of compressing the compression spring of the safety rib, the rigid friction between the compression spring guide sleeve and the guide bolt produces abnormal noise. In this application, the compression rubber 12 replaces the compression spring, the compression spring guide sleeve and the guide bolt, and uses the rubber deformation to trigger the safety switch action, thereby realizing the safety protection function while achieving a silent effect and improving the comfort of elevator operation.

[0027] In this embodiment, the auxiliary bracket 14 is detachably mounted on the side of the outer bottom surface of the elevator platform 10 .

[0028] Specifically, if Figure 3 As shown, the cross section of the auxiliary bracket 14 is stepped. One end of the auxiliary bracket 14 is fixed closely to the side of the outer bottom surface of the elevator platform 10, and the other end extends outward to fix the compression rubber 12 and the micro switch seat 13.

[0029] Specifically, the auxiliary bracket 14 may be an aluminum alloy bracket.

[0030] In this embodiment, the safety ribs 11 are installed along the door side and both sides of the elevator platform 10 . The safety ribs 11 are all located at the same height and are higher than the elevator platform 10 .

[0031] Specifically, the safety rib 11 is 5 mm higher than the elevator platform 10. When the passenger's limbs exceed the standing platform range, they will press against the safety rib 11 and trigger the linkage device of the safety rib 11.

[0032] Specifically, the safety retaining edge 11 is preferably an aluminum alloy frame with a rectangular cross section, which is easy to manufacture and process.

[0033] In this embodiment, Figure 2 、 Figure 3 As shown, the top of the compression rubber 12 is connected to the upper safety rib 11, and the bottom of the compression rubber 12 is fixed to the auxiliary bracket 14. The micro switch seat 13 is electrically connected to the elevator safety circuit, and the compression rubber 12 is linked to the micro switch seat 13. Specifically, a compression rubber 12 and a micro switch seat 13 are provided under each side of the safety rib 11 of the elevator platform 10. The micro switch seat 13 is adjacent to the compression rubber 12. The compression rubber 12, micro switch seat 13, and safety rib 11 are located in the same longitudinal plane and on the same straight line.

[0034] Specifically, if Figure 2 As shown, microswitch base 13 includes microswitch 131. Normally, microswitch 131 is disconnected from the elevator safety circuit and in contact with safety rib 11. Microswitch base 13 is bolted to auxiliary bracket 14, lower than compression rubber 12. A gasket is provided at the connection between microswitch base 13 and auxiliary bracket 14. When a passenger's limbs exceed the standing platform and press against safety rib 11, compression rubber 12 attached to the underside of safety rib 11 is retractable, compressing safety rib 11. This compresses safety rib 11, causing it to move downward, pushing microswitch 131 downward and contacting the elevator safety circuit. The elevator safety circuit triggers the elevator to stop, preventing a jam. Once the pressure from safety rib 11 is relieved, the elevator can resume normal operation.

[0035] Specifically, the elevator's safety circuit is connected to the elevator's brake. During normal operation, the brake is inoperative, and the elevator ascends or descends at a constant speed. However, if an emergency situation requires stopping, the brake immediately activates, rubbing against the drive gear or chain to bring the elevator to a rapid stop. Simultaneously, the brake disconnects the elevator's drive system, halting the elevator.

[0036] Specifically, a decorative panel 15 is provided on the underside of the safety rib 11 to shield the compression rubber 12 and microswitch base 13. This panel also shields the compression rubber 12 and the switch, enhancing the aesthetics of the device. As shown in the figure, the decorative panel 15 has an L-shaped cross-section with its opening facing the compression rubber 12 and microswitch base 13. The bottom of the decorative panel 15 is bolted to the auxiliary bracket 14.

[0037] In this embodiment, a novel safety rib device for a platform elevator operates as follows: A compression rubber 12 and a microswitch 131 are secured to an auxiliary bracket 14 fixed to the car floor, and then the safety rib 11 above is secured to the compression rubber 12. When pressure is applied to the safety rib 11, the compression rubber 12 activates the microswitch 131, causing the elevator to stop. When the pressure on the safety rib 11 is released, the elevator resumes operation.

[0038] In this embodiment, a novel safety side guard device for a platform elevator is used as follows: after the auxiliary bracket 14 is bolted to the car platform, a micro switch 131 is secured to the auxiliary bracket 14. The compression rubber 12 is secured to the aluminum alloy side guard and then to the auxiliary bracket 14. The micro switch 131 and the mounting bracket are adjustable, and the switch's operating stroke can be adjusted to be less than the compression stroke of the compression rubber 12.

[0039] In summary, the technical solution of this application has the following beneficial effects:

[0040] 1. Compared with the existing technology, during the compression of the compression spring by the safety retaining edge, the rigid friction between the compression spring guide sleeve and the guide bolt produces abnormal noise, which affects the comfort of the elevator. The utility model replaces the compression spring, the compression spring guide sleeve and the guide bolt with compressed rubber, and uses the deformation of the rubber to trigger the action of the safety switch, thereby realizing the safety protection function while solving the problem of abnormal noise, achieving a silent effect, and improving the comfort of elevator operation.

[0041] 2. In this utility model, when the safety rib is under pressure, the rubber is compressed, actuating the microswitch, stopping the elevator. Once the pressure from the safety rib is released, the elevator resumes operation. This device is simple and easy to install and maintain, with low cost. It is highly sensitive, requiring only a small amount of pressure to trigger the device, stopping the elevator and preventing it from getting stuck. Once the pressure is released, the elevator resumes normal operation.

[0042] The above are merely exemplary embodiments of the present application and are not intended to limit the scope of protection of the present application. The scope of protection of the present application is determined by the appended claims.
