Description

Technical Field

[0001] This utility model belongs to the technical field of elevator counterweight protection, and in particular relates to an elevator counterweight protection component and an elevator. Background Technology

[0002] Elevator counterweight protection components are a set of safety facilities installed in the elevator pit. Their main function is to effectively isolate the operating area below the counterweight, thereby preventing installation, maintenance and inspection personnel from accidentally entering the vertical operating space of the counterweight when working in the pit, avoiding serious personal injury accidents such as mechanical impact and crushing, and providing crucial passive safety protection for personnel working in this special workplace of the pit.

[0003] Currently, existing elevator counterweight protection components are generally detachably installed onto the counterweight guide rail using bolts and other fasteners. This requires workers to perform tedious tightening and disassembly operations with wrenches and other tools when installing or maintaining the counterweight buffer or conducting safety inspections. This process is time-consuming and labor-intensive, resulting in low work efficiency. This not only increases the workload of disassembly and assembly, but more importantly, personnel entering the confined counterweight operating area themselves face a high risk of mechanical compression or impact, posing a potential safety hazard.

[0004] Furthermore, as provided in the patent document CN219489320U, an elevator counterweight protection device and elevator counterweight are provided. The guardrail components are connected and fixed on the guardrail bracket by fasteners such as bolts. As a result, during subsequent installation and maintenance of the elevator, a wrench is required to disassemble the fasteners, which makes the entire counterweight buffer distance detection time and maintenance time still very long. There is a defect in terms of operational convenience that urgently needs to be improved. Utility Model Content

[0005] In view of this, it is necessary to provide an elevator counterweight protection component and an elevator that are easy to install and disassemble.

[0006] An elevator counterweight protection component, comprising: The side guard plate assembly includes a first side guard plate and a second side guard plate, wherein the first side guard plate and the second side guard plate are disposed on the two outer sides of the counterweight guide rail and are respectively used to connect the adjacent counterweight guide rails; A front protective plate is disposed on one side of the side protective plate group and connected to the first side protective plate and / or the second side protective plate, so that the front protective plate and the side protective plate group enclose a protective cavity. The first side protective plate and / or the second side protective plate are provided with an opening clip. The bent end of the front protective plate is inserted into the opening clip and clamped and fixed by the opening clip, thereby fixing the front protective plate to the side protective plate assembly.

[0007] It is understandable that the front protective plate is clamped and fixed by using opening clips on the first and / or second protective plates, so that the front protective plate can be installed and removed by inserting and pulling it out from the front of the opening clips or by sliding it in and out from the top. This facilitates the on-site installation of the elevator counterweight protection components and subsequent maintenance operations.

[0008] In one embodiment, the opening clip includes a connecting plate, a first clamping plate, and a second clamping plate. One end of the first clamping plate and one end of the second clamping plate are respectively disposed on both sides of the connecting plate. The other ends of the first clamping plate and the second clamping plate form clamping openings for clamping and fixing the front protective plate, and are respectively connected to the connecting plate. Furthermore, the ends of the first clamping plate and the second clamping plate that are opposite to the connecting plate are respectively abutted and limited by the bent end. The connecting plate body is attached to the first bent plate portion of the first side protective plate and connected to the first bent plate portion; and / or, the connecting plate body is attached to the second bent plate portion of the second side protective plate and connected to the second bent plate portion.

[0009] In one embodiment, the first side protective plate and / or the second side protective plate are provided with elongated slots through which a connector can pass, wherein the connector can press and fix the corresponding first side protective plate or second side protective plate to the counterweight guide rail. In the thickness direction of the front protective plate, the mounting position of the connector within the elongated slot can be adjusted.

[0010] It is understandable that by utilizing the elongated slot structure on the first and / or second protective plates, the installation position of the first and / or second protective plates on the counterweight guide rail can be adjusted. This not only reduces the dimensional control precision of the first and / or second protective plates, thus reducing costs, but also facilitates the on-site installation of the elevator counterweight protection components.

[0011] The front protective plate is provided with a measuring hole and an observation hole, which are respectively connected to the protective chamber. The measuring hole extends along the height direction of the side protective plate assembly. The elevator counterweight protection component also includes a measuring ruler, which has a straight ruler part marked with graduations. The straight ruler part can pass through the measuring hole and extend into the protective chamber. Furthermore, the graduations on the straight ruler part located in the protective chamber can be observed through the observation hole.

[0012] Understandably, by setting dedicated measuring and observation holes on the front protective panel, operators only need to insert the graduated ruler into the measuring hole and read the measurement data through the observation hole to directly complete the detection of the counterweight buffer distance or related maintenance work. In this process, there is no need to disassemble the entire elevator counterweight protection component. Not only is the operation process extremely simple and can significantly shorten the operation time, thereby greatly improving the operation efficiency, but it can also fundamentally eliminate the potential safety risks faced by operators entering the counterweight operating space, achieving a dual improvement in safety and efficiency.

[0013] In one embodiment, the number of observation holes is set to multiple, and the multiple observation holes are arranged sequentially at intervals along the height direction of the side protective plate assembly; Furthermore, the scale on the ruler portion that extends into the protective chamber can be observed through the observation hole.

[0014] It is understandable that by using multiple observation holes arranged at intervals along the height of the side protection plate assembly to read measurement data separately, the elevator counterweight protection component is suitable for detecting different counterweight buffer distances, thus meeting the usage requirements of different elevators.

[0015] In one embodiment, the number of observation holes is set to multiple, and the multiple observation holes are combined to form multiple rows of observation hole groups, wherein the observation holes in each row of the observation hole groups are arranged sequentially at intervals along the height direction of the side protective plate group; The observation hole group in multiple rows is arranged on both sides of the measuring hole in the width direction of the front protective plate.

[0016] Understandably, the arrangement of multiple rows of observation holes allows operators to read the scale on the ruler from different angles. This not only ensures that the measurement data can be read, but also expands the angle from which operators can read the measurements, thereby further facilitating their operation.

[0017] In one embodiment, the measuring ruler further includes a handle portion, which is disposed at one end of the ruler portion and connected to the ruler portion; When the ruler portion passes through the measuring hole and extends into the protective chamber, the handle portion extends outward through the measuring hole.

[0018] Understandably, operators can grasp the measuring ruler through the handle to perform related operations, which further facilitates the operator's measurement operations.

[0019] In one embodiment, a support member is provided on the front protective plate, and the support member encloses and forms a limiting cavity; The measuring ruler is housed within the limiting cavity and abuts against the support member for limiting.

[0020] Understandably, placing the measuring ruler directly on the front protective panel eliminates the need for workers to carry their own measuring tools. They can quickly begin measuring operations on-site by simply picking them up. This not only greatly simplifies preparation and further enhances the convenience of measurement operations, but also effectively avoids the problem of forgetting or losing tools due to carrying them themselves, thus ensuring the continuity and efficiency of the work.

[0021] In one embodiment, the number of the front protective panels is set to multiple, and the multiple front protective panels are stacked sequentially along the height direction of the side protective panel group.

[0022] It is understandable that assembling multiple front protective panels to form the front protective structure of the elevator counterweight protection component can reduce the size and weight of a single front protective panel, making it easier to handle and transport the elevator counterweight protection component in the future, thereby improving the convenience and flexibility of the elevator counterweight protection component in logistics turnover and on-site handling.

[0023] In one embodiment, the front protective panel is provided with a handle, and the front protective panel can be gripped by the handle.

[0024] Understandably, using a handle to provide a stable and effortless gripping point for the front panel makes it easier and more convenient to move.

[0025] This application also provides an elevator, including the elevator counterweight protection component described above.

[0026] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: The elevator counterweight protection component and elevator for which this application seeks protection, by setting dedicated measuring holes and observation holes on the front protective panel, allow operators to directly complete the detection or related maintenance work of the counterweight buffer distance simply by inserting the graduated ruler into the measuring hole and reading the measurement data through the observation hole. In this process, it is not necessary to disassemble the entire elevator counterweight protection component, which not only simplifies the operation process and significantly shortens the operation time, thereby greatly improving the operation efficiency, but also fundamentally eliminates the potential safety risks faced by operators entering the counterweight operating space, achieving a dual improvement in safety and efficiency.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] like Figures 1 to 5 As shown, the elevator counterweight protection assembly 100 provided in this application includes a side protection plate assembly 10, a front protection plate 20, and a measuring ruler 30. The side protection plate assembly 10 includes a first side protection plate 11 and a second side protection plate 12. The first side protection plate 11 and the second side protection plate 12 are disposed on the two outer sides of the counterweight guide rail 200 and are used to connect adjacent counterweight guide rails 200 respectively. The front protection plate 20 is disposed on one side of the side protection plate assembly 10 and is connected to the first side protection plate 11 and / or the second side protection plate 12 so that the front protection plate 20 and the side protection plate assembly 10 enclose a protective chamber 101. The first side protection plate 11 and / or the second side protection plate 12 are provided with an opening clip 13. The bent end 210 of the front protection plate 20 is inserted into the opening clip 13 and clamped and fixed by the opening clip 13, thereby fixing the front protection plate 20 to the side protection plate assembly 10. This allows the front protective plate 20 of this application to be installed and removed by inserting and pulling it out from the front or sliding it in and out from the top of the opening clip 13, which further facilitates the on-site installation and subsequent maintenance of the elevator counterweight protection component 100. It should be noted that the first side protective plate 11 and the second side protective plate 12 mentioned above can both be integral plate structures.

[0038] Here, opening clips 13 are respectively installed on the first side protective plate 11 and the second side protective plate 12. The front protective plate 20 can be assembled and connected to the first side protective plate 11 and the second side protective plate 12 via the two opening clips 13, thereby improving the stability of the front protective plate 20 when assembled on the side protective plate assembly 10. Of course, in other embodiments, the front protective plate 20 can also be fixed to the first side protective plate 11 or the second side protective plate 12 using only one opening clip 13, which will not be elaborated upon here.

[0039] like Figure 2 , Figure 4 As shown, in one embodiment, the opening clip 13 includes a connecting plate 131, a first clamping plate 132, and a second clamping plate 133. The first clamping plate 132 and the second clamping plate 133 are disposed on both sides of the connecting plate 131 and are respectively connected to the connecting plate 131, specifically, they can be connected to the connecting plate 131 as a whole. The first clamping plate 132 and the second clamping plate 133 each form a clamping opening on the side away from the connecting plate 131 for clamping and fixing the front protective plate 20. Furthermore, the ends of the first clamping plate 132 and the second clamping plate 133 on the side away from the connecting plate 131 respectively abut and limit the bending end 210 for clamping and fixing the front protective plate 20.

[0040] Here, the first clamping plate 132 and the second clamping plate 133 are respectively connected to the connecting plate 131 as a whole. Specifically, they can be made by bending a straight part, so that the opening clip 13 can use the elastic deformation of the first clamping plate 132 and the second clamping plate 133 to clamp and fix the bent end 210 inserted into the opening clip 13. Of course, in other embodiments, the opening clip 13 can also be formed by connecting the independently set connecting plate 131, the first clamping plate 132 and the second clamping plate 133, which will not be elaborated here.

[0041] like Figure 4 As shown, in this embodiment, the connecting plate 131 is attached to the first bent plate portion 111 of the first side protective plate 11 and connected to the first bent plate portion 111. Specifically, the connecting plate 131 can be fixed to the first side protective plate 11 by welding, and the opening clip 13 can be assembled on the first side protective plate 11.

[0042] Similarly, such as Figure 2 As shown, the connecting plate 131 can also be attached to the second bent plate portion 121 of the second side protective plate 12 and welded to the second bent plate portion 121 to realize the assembly connection of the opening clip 13 on the second side protective plate 12.

[0043] As shown in the figure, in one embodiment, the first side protective plate 11 and / or the second side protective plate 12 are provided with elongated slots 1112, through which a connector (not shown) can pass. The connector can press and fix the corresponding first side protective plate 11 or second side protective plate 12 to the counterweight guide rail 200. Furthermore, in the thickness direction Y of the front protective plate 20, the installation position of the connector in the elongated slots 1112 can be adjusted, so that the first side protective plate 11 and / or the second side protective plate 12 can be adjusted relative to the counterweight guide rail 200 in the thickness direction Y of the front protective plate 20. This not only reduces the dimensional control accuracy of the first side protective plate 11 and / or the second side protective plate 12, thus reducing costs, but also facilitates the on-site installation of the elevator counterweight protection component 100.

[0044] Here, both the first side protective plate 11 and the second side protective plate 12 have multiple elongated slots 1112. Furthermore, the first side protective plate 11 and the second side protective plate 12 can be clamped and fixed to the counterweight guide rail 200 using connectors that pass through the multiple elongated slots 1112. These connectors can specifically be bolts, screws, etc. Of course, in other embodiments, only the first side protective plate 11 or the second side protective plate 12 may have elongated slots 1112 for the connectors to pass through; this will not be elaborated upon here.

[0045] like Figures 1 to 5 As shown, in one embodiment, the front protective plate 20 is provided with a measuring hole 21 and an observation hole 22, which are respectively connected to the protective chamber 101. The measuring hole 21 extends along the height direction Z of the side protective plate assembly 10. Furthermore, the elevator counterweight protection assembly 100 also includes a measuring ruler 30, which includes a ruler portion 31 marked with graduations (not shown). The ruler portion 31 can pass through the measuring hole 21 and extend into the protective chamber 101. The graduations on the ruler portion 31 located in the protective chamber 101 can be observed through the observation hole 22. Here, the first side protective plate 11 and the second side protective plate 12 can be specifically fixed to the adjacent counterweight guide rail 200 using screws, bolts, or other connecting components. This allows operators to simply insert the graduated ruler 31 into the measuring hole 21 and read the measurement data through the observation hole 22 to directly complete the detection or related maintenance work of the counterweight buffer distance. In this process, there is no need to disassemble the entire elevator counterweight protection component 100. Not only is the operation process extremely simple and the operation time significantly shortened, thereby greatly improving the operation efficiency, but it also fundamentally eliminates the potential safety risks faced by operators entering the counterweight operating space, achieving a dual improvement in safety and efficiency.

[0046] It should be noted that the ruler part 31 on the measuring ruler 30 of this application can be used to measure the distance between the counterweight assembly on the counterweight guide rail 200 and the counterweight buffer located in the pit, and can also measure the compression distance of the counterweight buffer when it is compressed by the counterweight assembly, so as to meet the needs of counterweight buffer distance detection and maintenance during elevator use.

[0047] like Figure 1 , Figure 5 As shown, in one embodiment, the number of front protective plates 20 is set to multiple, and the multiple front protective plates 20 are stacked sequentially along the height direction Z of the side protective plate group 10, so that the front protective structure of the elevator counterweight protection component 100 is formed by combining multiple front protective plates 20. This can reduce the size and weight of a single front protective plate 20, so as to facilitate the subsequent handling and transportation of the elevator counterweight protection component 100, thereby improving the convenience and flexibility of the elevator counterweight protection component 100 in logistics turnover and on-site handling.

[0048] Here, the number of front protective plates 20 is set to three. Of course, in other embodiments, the number of front protective plates 20 can also be two, four, or even more. The specific number can be selected according to the needs of use, which will not be elaborated here.

[0049] like Figure 1 , Figure 5 As shown, in one embodiment, a handle 220 is provided on the front protective plate 20, and the front protective plate 20 can be gripped by the handle 220. This allows the handle 220 in this embodiment to provide a stable and effortless gripping point for the front protective plate 20, making it easier and more convenient to move the front protective plate 20.

[0050] Here, the number of handles 220 is set to two, and the two handles 220 are located on the upper and lower sides of the measuring hole 21 on the front protective plate 20 in the height direction Z of the side protective plate assembly 10. Of course, in other embodiments, the two handles 220 can also be located in other positions on the front protective plate 20, or the number of handles 220 can be set to one, three, or more, which will not be elaborated here.

[0051] like Figure 1 , Figure 5As shown, in one embodiment, the number of observation holes 22 is set to multiple, and the multiple observation holes 22 are arranged sequentially at intervals along the height direction Z of the side protective plate assembly 10; and the scale on the ruler portion 31 located in the protective chamber 101 can be observed through one of the observation holes 22. That is to say, this embodiment can use multiple observation holes 22 arranged sequentially at intervals along the height direction Z of the side protective plate assembly 10 to read measurement data respectively, so that the elevator counterweight protection component 100 is suitable for detecting different counterweight buffer distances to meet the usage requirements of different elevators.

[0052] like Figure 1 , Figure 5 As shown, multiple observation holes 22 are combined to form a multi-row observation hole group 221. The multi-row observation hole group 221 is set on both sides of the measuring hole 21 in the width direction X of the front protective plate 20, so that the operator can read the scale of the ruler part 31 from different angles. This not only ensures that the measurement data can be read, but also expands the angle for the operator to read the measurement, thereby further facilitating the operator's operation.

[0053] Here, the number of observation hole groups 221 is six rows, and the six rows of observation hole groups 221 are symmetrically arranged on both sides of the measuring hole 21. Of course, in other embodiments, the number of observation hole groups 221 may also be two, three, four, five, etc., which will not be elaborated here.

[0054] like Figure 5 As shown, in one embodiment, the measuring ruler 30 further includes a handle portion 32, which is disposed at one end of the ruler portion 31 and connected to the ruler portion 31. Specifically, the handle portion 32 and the ruler portion 31 can be connected as one unit. Furthermore, when the ruler portion 31 passes through the measuring hole 21 and extends into the protective chamber 101, the handle portion 32 extends outward through the measuring hole 21. This allows the operator to grasp the measuring ruler 30 using the handle portion 32 for related operations, and prevents the operator's line of sight from being obstructed by grasping the handle portion 32, thus further facilitating the operator's measurement operations.

[0055] Here, the handle portion 32 is vertically disposed at one end of the ruler portion 31 and is connected to the ruler portion 31 as an integral structure. Of course, in other embodiments, the handle portion 32 may also be disposed at the middle position of the ruler portion 31 or at any other position, and the included angle formed between the handle portion 32 and the ruler portion 31 may be 75°, 80°, 92°, 100°, etc., which will not be elaborated here.

[0056] like Figure 3As shown, in one embodiment, a support member 230 is provided on the front protective plate 20, and the support member 230 and the front protective plate 20 enclose a limiting cavity 201; and the measuring ruler 30 is partially housed in the limiting cavity 201 and abuts against the support member 230 for limiting, so that the measuring ruler 30 can be directly placed on the front protective plate 20. In this way, the operator no longer needs to carry the measuring tool himself, and can quickly start the measurement operation on site. This not only greatly simplifies the preparation work and further improves the convenience of the measurement operation, but also effectively avoids the problem of forgetting or losing the tool due to carrying it himself, thereby ensuring the continuity and efficiency of the work.

[0057] Here, the support member 230 is configured as a U-shaped bent member, specifically fixed to the front protective plate 20 by welding. Two support members 230 spaced apart on both sides of the width direction X of the front protective plate 20 can jointly support the measuring ruler 30. Of course, in other embodiments, the support member 230 can also be configured as an L-shaped bent member. The number used to support the measuring ruler 30 can be set to one, three, four, or even more depending on the application requirements; this will not be elaborated upon here.

[0058] In addition, this application also provides an elevator, including the elevator counterweight protection component 100 described above.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
