Description
Technical Field
[0001] This utility model relates to the field of elevator safety protection technology, specifically to an elevator equipment guardrail. Background Technology
[0002] Elevator guardrails play a crucial role in the operation and maintenance of elevator equipment. However, traditional elevator guardrails have many problems in practical applications.
[0003] The installation of traditional elevator equipment railings is quite complex, mostly using welding and bolting for splicing. Welding installation requires professional welding equipment and technicians, which is not only time-consuming, but also time-consuming for the installation and dismantling of the railings, affecting the overall work progress. The size and shape of traditional railings are often fixed, which makes them either impossible to install on elevator shafts with special shapes or sizes, or they do not fit the space well after installation, resulting in protective loopholes and failing to fully realize the safety protection function of the railings.
[0004] For example, in an elevator safety railing with announcement number CN220283220U, the rear protection unit is located between two rear side uprights, and the side protection unit is located between the front and rear uprights. The rear protection unit, side protection unit, and uprights form a maintenance and protection space. It is also connected to the upper beam of the elevator car frame, thereby improving the overall protection effect of the elevator safety railing and preventing the occurrence of safety accidents.
[0005] A type of elevator safety railing (CN222293312U) includes a base with a column fixedly installed on its upper surface, a protective net fixedly installed on the outer surface of the column, and several upper assembly bases fixedly installed on the outer surface of another column. By using the base, column, and two protective nets in combination, the fault tolerance of multiple fixed-length elevator safety railing bodies after assembly is effectively reduced. However, the aforementioned elevator safety railing is complex and time-consuming to install, and its fixed size and shape make it difficult to adapt to different elevator shafts, affecting installation efficiency and protective effect. Other problems exist, such as insufficiently stable connections between railing panels, leading to deformation, loosening, or even breakage. Some railings use simple plug-in or snap-fit connections, which are prone to loosening over time, resulting in decreased overall stability. Relative movement between components easily causes friction and wear, shortening the railing's lifespan and potentially affecting the normal operation of the elevator equipment due to wear debris. Loose connections can also damage the railing panels, affecting their structural integrity and reducing protective effect. Utility Model Content
[0006] The purpose of this utility model is to provide an elevator equipment guardrail to solve the problems mentioned in the background art, such as the complex and time-consuming installation of elevator equipment guardrails, the fixed size and shape making it difficult to adapt to different elevator shafts, which affects the installation efficiency and protective effect, the unstable connection between guardrail panels, the risk of people and objects being trapped, the easy wear of components, and the reduced protective performance.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an elevator equipment guardrail, comprising a support frame and a first guardrail plate disposed at the front end of the support frame; a second guardrail plate disposed at the front end of the support frame, and the second guardrail plate being disposed at its lower end; a free-moving mechanism disposed at the front end of the support frame, and a guide groove fixedly installed on the left side of the front end of the support frame, and two guide grooves being evenly distributed around the support frame as the center of symmetry; a positioning post fixedly installed on the upper right side of the second guardrail plate, and two positioning posts being evenly distributed around the support frame as the center of symmetry; a positioning and fixing mechanism disposed on the first guardrail plate, and a positioning groove opened on the lower left side of the first guardrail plate, and two positioning grooves being evenly distributed around the support frame as the center of symmetry.
[0008] Furthermore, the free-moving mechanism includes a first guide block fixedly installed at both ends of the first guardrail plate, and the first guide block cooperates with the guide groove; and a second guide block fixedly installed at both ends of the second guardrail plate, and the second guide block cooperates with the guide groove.
[0009] Furthermore, the positioning and fixing mechanism includes a return spring installed at the upper end of the positioning groove, and a baffle installed at the lower end of the return spring, with the baffle slidably connected to the positioning groove.
[0010] Furthermore, the lower end of the baffle corresponds to the upper end of the positioning post, and a fixing buckle is fixedly installed on the right side of the lower end of the first guardrail, with two fixing buckles evenly distributed around the first guardrail as the center of symmetry.
[0011] Furthermore, the upper end of the second guardrail is provided with a placement groove, and two placement grooves are evenly distributed with the second guardrail as the center of symmetry. A fixing plate is fixedly installed at the lower end of the placement groove.
[0012] Furthermore, a fixed ball is nested within the sphere on the right side of the middle of the fixed plate, and two fixed balls are evenly distributed with the fixed plate as the center of symmetry.
[0013] Furthermore, the fixed ball and the lower end of the fixed buckle cooperate with each other, and a compression spring is installed inside the upper right end of the fixed plate, with the left end of the compression spring installed on the right end of the fixed ball.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. During installation, simply match the guide groove at the front end of the support frame with the first guide blocks on both sides of the first guardrail. Adjust the position of the first guardrail by matching the guide groove with the first guide blocks. Then match the guide groove with the second guide blocks on both sides of the second guardrail. The first guardrail and the second guardrail can be quickly spliced together. When installing guardrails in the elevator machine room, workers can quickly assemble the various components together, improving installation efficiency.
[0016] Furthermore, based on the actual spatial layout of the elevator equipment, whether it is a conventional rectangular elevator shaft or an irregularly shaped shaft formed by special building structures, the guardrails can be reasonably spliced to make them fit the spatial contours closely, providing comprehensive and effective protection. This avoids the problem of inadequate protection caused by unsuitable guardrail sizes and ensures the safety of the elevator operating area.
[0017] Furthermore, it improves the overall efficiency of elevator installation or maintenance. When the guardrail is damaged, only the damaged splicing module needs to be replaced, instead of replacing the entire guardrail, reducing material waste. The guardrail can be disassembled into multiple small parts for transportation. These small parts are small in size and light in weight, greatly reducing the space occupied. During transportation, the transportation space can be used more rationally, reducing transportation costs.
[0018] 2. The fixing buckle at the lower end of the first guardrail is placed in the groove on the right end. Then, the lower end of the fixing buckle presses the fixing ball on the fixing plate. The fixing ball presses the compression spring. Then, when the fixing buckle groove corresponds with the fixing ball, the compression spring pushes the fixing ball, so that the fixing ball locks the fixing buckle, thus fixing the first guardrail and the second guardrail together to form a stable overall structure and enhance the resistance to deformation, loosening and breakage.
[0019] Furthermore, the panels are tightly fixed together with no gaps, fundamentally avoiding the risk of people or objects getting caught. No accidental injuries will occur due to gaps between the panels, providing more reliable protection for personnel safety. This reduces damage to the railings caused by friction and wear, decreases the cost and hassle of frequent railing replacements, and lowers the safety risks caused by railing damage. Loosening will not cause localized damage, thus affecting the overall protective function of the railing. Attached Figure Description
