However, because the guide tube is a closed space, maintenance personnel cannot monitor the operating status of the weight and wire rope, or the degree of fatigue or wear on some of the wire ropes. If the wire rope breaks, the weight will fall out of restraint. If the weight falls out of control and strikes structures such as the door panel head and the sill bracket, these deformed parts need to be replaced, making maintenance difficult and costly. This also poses a safety threat to maintenance personnel if they are present in the elevator pit.

[0004] Therefore, there is an urgent need for an elevator landing door weight assembly and an elevator to solve the above-mentioned technical problems. Utility Model Content

[0033] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0036] At the same time, the meaning of "and / or" or "and / or" appearing in the full text includes three options. Taking "A and / or B" as an example, it includes option A, or option B, or an option in which both A and B are satisfied.

[0037] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0038] The utility model provides an elevator floor door weight hammer assembly, aiming to solve the technical problem in the existing technical solution that the weight hammer assembly is likely to damage other elevator floor door components or endanger the personal safety of maintenance personnel after falling out of control.

[0039] In an embodiment of the present invention, an elevator landing door weight assembly is provided, comprising a guide assembly 1 and a landing door weight 2. The landing door weight 2 moves under the guidance of the guide assembly 1 by being pulled by a steel wire rope 3.

[0040] The guide assembly 1 includes a guide member 11 and a guide frame 12. The guide member 11 is clamped on the guide frame 12 to be fixed to the elevator landing door system through the guide frame 12.

[0041] The landing door weight 2 includes a weight body 21 and a blocking member 22 disposed on the weight body 21;

[0042] The blocking member 22 is located above the guide member 11 in the direction of gravity. When the wire rope 3 pulling the weight body 21 to move breaks, the guide member 11 supports the blocking member 22 to prevent the weight body 21 from falling.

[0043] Ginseng Figure 1 As shown, the elevator landing door system includes a landing door device 4 and a sill 5. The landing door device 4 includes a door frame 41 and two hanging plates 42 mounted on the door frame 41. The two hanging plates 42 can slide relative to each other on the door frame 41. A pair of landing door panels are mounted on the hanging plates 42, which drive the landing door panels to open and close. When closed, the landing door panels need to be able to remain closed to prevent passengers from prying at the door or leaning on the door panels and falling into the hoistway.

[0044] The prior art provides a weight assembly, which consists of a weight and a guide tube. The weight runs in the guide tube by the traction of a steel wire rope, and the other end of the steel wire rope is connected to a hanging plate away from the weight, so that when the elevator floor door panel is closed, the gravity of the weight is converted into a self-closing force of the floor door panel, so that the elevator floor door panel can still maintain the ability to close itself when the passenger is pulling the door or leaning on the floor door panel. However, since the inside of the guide tube is a closed space, maintenance personnel are unable to detect the operating status of the weight and the wire rope, and the fatigue or wear of some wire ropes. Once the wire rope breaks, the weight will fall off due to loss of restraint. After the weight falls out of control and hits structures such as the door panel head and the sill bracket, these deformed parts need to be replaced. Maintenance is difficult and costly. If there are maintenance personnel in the elevator pit, it will also pose a threat to the personal safety of the maintenance personnel. If the weight is not found in time, it will also cause insufficient self-closing force of the floor door panel, resulting in a dangerous situation where subsequent elevator passengers fall into the shaft.

[0045] Therefore, please refer to Figures 2 to 4 As shown, the present application proposes an elevator floor door weight assembly, which includes a guide assembly 1 and a floor door weight 2. The floor door weight 2 moves up and down under the guidance of the guide assembly 1 through the traction of a steel wire rope 3.

[0046] The guide assembly 1 includes a guide member 11 and a guide frame 12. The guide frame 12 is fixed to a fixing device of the elevator floor door system by a fastening device (such as a bolt). The fixing device can be an elevator floor door panel or a fixing rod 6 connected between the floor door device 4 and the sill 5, or other fixing devices. The guide member 11 is clamped on the guide frame 12 so that the guide member 11 is fixed to the elevator floor door system.

[0047] The landing door weight 2 includes a weight body 21 and a blocking member 22 disposed on the weight body 21. The blocking member 22 can be disposed anywhere on the weight body 21, as long as it is positioned above the guide member 11 in the direction of gravity when the landing door weight 2 is pulled by the wire rope 3. Preferably, the blocking member 22 is disposed at an end of the weight body 21, but this is not specifically limited in this embodiment.

[0048] When the elevator floor door weight assembly of the present application is installed and used, the guide member 11 is clamped on the guide frame 12, and the guide frame 12 is fixedly installed on the elevator floor door system. One end of the wire rope 3 is connected to the weight body 21 of the floor door weight 2, and the weight body 21 is placed within the guide range of the guide member 11 in the direction of gravity, and the blocking member 22 is located above the guide member 11 in the direction of gravity. In this way, the weight body 21 can move under the guidance of the guide member 11 through the traction of the wire rope 3. At the same time, once the wire rope 3 breaks, the blocking member 22 will be supported by the guide member 11 when the floor door weight 2 falls freely, thereby preventing the weight body 21 from falling off continuously due to loss of restraint, damaging other structural components of the elevator system and threatening the personal safety of elevator pit maintenance workers.

[0049] The technical solution of the present utility model proposes an elevator floor door weight assembly, including a guide assembly 1 and a floor door weight 2. The floor door weight 2 moves under the guidance of the guide assembly 1 through the traction of a wire rope 3. The guide assembly 1 includes a guide member 11 and a guide frame 12. The guide member 11 is hooped on the guide frame 12 to be fixed to the elevator floor door system through the guide frame 12; the floor door weight 2 includes a weight body 21 and a blocking member 22 arranged on the weight body 21; the blocking member 22 is located above the guide member 11 in the direction of gravity. When the wire rope 3 that pulls the weight body 21 to move breaks, the guide member 11 supports the blocking member 22 to prevent the weight body 21 from falling. In the present application, a blocking member 22 is provided on the weight body 21, and the blocking member 22 is located above the guide member 11 in the direction of gravity. When the wire rope 3 that pulls the weight body 21 to move breaks, the weight body 21 falls freely, and the guide member 11 supports the blocking member 22, thereby preventing the weight body 21 from continuing to move under the guidance of the guide member 11, thereby avoiding the problem that the weight body 21 falls off continuously due to loss of restraint, damaging other structural components of the elevator system and threatening the personal safety of elevator pit maintenance workers.

[0050] Furthermore, the interior of the guide member 11 is hollowed out to form an inner wall 111 , and the projection of the blocking member 22 in the gravity direction at least partially protrudes from the inner wall 111 .

[0051] Understandable, please refer to Figures 2 to 9 As shown, since the weight body 21 moves up and down under the guidance of the guide member 11, the guide member 11 is a guide structure with an internal hollow design, and the internal hollow part forms an inner wall 111, as shown in FIG. Figure 8 and Figure 9As shown, the guide member 11 can be cylindrical or cubical, with a circular inner wall 111 formed therein. Of course, in other embodiments, the guide member 11 can also be of other shapes, and the inner wall 111 formed therein can also be of other shapes, as long as the weight body 21 can move under the guidance of the guide member 11. The blocking member 22 is located above the guide member 11 in the direction of gravity, and the projection of the blocking member 22 in the direction of gravity at least partially protrudes from the inner wall 111. Figure 5 and Figure 6 As shown, the blocking member 22 can be a circular sheet or a square sheet, or of course other sheet structures. A mounting hole is provided in the middle of the sheet structure to facilitate the blocking member 22 to be mounted on the weight body 21. In other embodiments, the blocking member 22 can also be Figure 7 The non-circular structure shown has a notch, which can be of any shape. The blocking member 22 can also be a sheet-like structure with a notch of other shapes. When the wire rope 3 pulling the weight body 21 breaks, the portion of the blocking member 22 protruding from the inner wall 111 can be supported by the guide member 11 during the free fall of the door weight 2, thereby preventing the weight body 21 from continuing to move under the guidance of the guide member 11. Preferably, as Figure 3 and Figure 4 As shown, the projection of the blocking member 22 in the direction of gravity protrudes from the inner wall 111, so that the guide member 11 and the blocking member 22 have more contact area, ensuring the supporting effect of the guide member 11. Of course, it is also possible to adopt Figure 7 The non-circular sheet-like blocking member 22 shown may also be other sheet-like structures with a notch, as long as it is ensured that the portion of the blocking member 22 protruding from the inner wall 111 can be supported by the guide member 11 when the wire rope 3 breaks.

[0052] Furthermore, the guide member 11 includes an outer wall 112 , and a projection of an outer edge 221 of the blocking member 22 in the direction of gravity at least partially protrudes from the outer wall 112 of the guide member 11 .

[0053] Understandable, please refer to Figures 8 and 9 As shown, the guide member 11 has an outer wall 112. Figures 5 to 7 As shown, the blocking member 22 has an outer edge 221, and the projection of the outer edge 221 in the direction of gravity at least partially protrudes from the outer wall 112, so that when the guide member 11 supports the blocking member 22, a larger portion of the blocking member 22 in the horizontal direction is supported by the guide member 11, thereby further ensuring the supporting effect of the guide member 11. Of course, preferably, as Figure 4 As shown, the projection of the outer edge 221 of the blocking member 22 in the direction of gravity protrudes from the outer wall 112 of the guide member 11. In this way, all parts of the upper surface of the guide member 11 can be used to support the blocking member 22, and the supporting effect is better. Of course, it is also possible to use Figure 7 The non-circular sheet-like blocking member 22 shown may also be other sheet-like structures with a notch shape, as long as it is ensured that the portion of the blocking member 22 protruding from the outer wall 112 can be supported by the guide member 11 when the wire rope 3 breaks.

[0054] It should be noted that for the above examples, no matter how Figure 8 The cylindrical guide 11 is also selected as Figure 9 The guide member 11 of a cube shape or other shapes can be adapted as follows. Figure 5 Whole round flakes, such as Figure 7 The disc-shaped blocking member 22 with a notch or Figure 6 The whole square sheet, the square sheet with notch or other notch or no-notch shaped blocking member 22. Figure 8 The cylindrical guide 11 is also selected as Figure 9 The guide member 11 may be a cube or any other shape, and the clamp groove 1211 of the guide frame 12 may be circular, square or any other shape, as long as the guide member 11 can be clamped by the guide frame 12 and not fall off.

[0055] Furthermore, the guide frame 12 is L-shaped, including a flat plate portion 121 extending horizontally and a vertical portion 122 extending vertically. A clamp groove 1211 is provided on the flat plate portion 121 , and the guide member 11 is clamped in the clamp groove 1211 .

[0056] Understandable, please refer to Figures 8 to 10As shown, in this embodiment, the guide frame 12 is provided with an L-shaped structure including a flat plate portion 121 and a vertical portion 122. A semi-open clamp groove 1211 is dug on the flat plate portion 121. The guide member 11 is provided with a cylindrical shape with a hollow interior or a square shape or other irregular shapes. The guide member 11 is clamped in the semi-open clamp groove 1211 so that the guide member 11 can be stably fixed on the guide frame 12. In addition, the guide member 11 is set as a non-enclosed structure. The gap between the weight body 21 and the guide member 11 is not easily blocked by foreign objects. It can provide guidance for the weight body 21 without completely covering the weight body 21. Only a small part of the weight body 21 will be covered by the guide member 11 during movement. The wire rope 3 connected to the weight body 21 can also be completely exposed outside the guide member 11. In this way, maintenance personnel can easily detect the operating status of the weight body 21 and the wire rope 3, the fatigue level and wear level of the wire rope 3 during maintenance. If it is found that the weight body 21 or the wire rope 3 is not in good operating condition, the wire rope 3 is about to reach its fatigue life or is severely worn, the weight body 21 or the wire rope 3 can be replaced in time. This can directly prevent the weight body 21 from running freely without restraint due to the weight body 21 itself or the breakage of the wire rope 3. Moreover, during maintenance, if the guide member 11 or the guide frame 12 is found to be damaged, the corresponding component can be directly replaced, reducing the difficulty and cost of subsequent maintenance by maintenance personnel. In this embodiment, the running direction of the weight body 21 is constrained by the guide member 11 and the guide frame 12. The movement state of the weight body 21 can be observed at any time, and the processing cost is lower than that of the guide tube guiding solution in the prior art.

[0057] Furthermore, a groove 113 is provided on the outer surface of the guide member 11, and the clamp groove 1211 of the guide frame 12 is a major arc groove, which includes a semi-arc groove 1212 and clamp feet 1213 provided at both ends of the semi-arc groove 1212. The semi-arc groove 1212 clamps the groove 113, and the clamp feet 1213 are clamped in the groove 113.

[0058] For easy understanding, please refer to Figure 8 、 Figure 9 As shown, the outer surface of the guide member 11 is concavely provided with a groove 113. Figure 10As shown, the clamp groove 1211 of the guide frame 12 is a major arc groove, which includes a semi-arc groove 1212 and clamp feet 1213 arranged at both ends of the semi-arc groove 1212. The clamp feet 1213 are formed by the semi-arc groove 1212 continuing to extend toward the missing other half of the semi-arc. During installation, the guide member 11 can be pressed into the clamp groove 1211 so that the semi-arc groove 1212 can completely cover half of the groove 113 of the guide member 11, and the clamp feet 1213 continue to cover the other half of the groove 113. This not only facilitates the installation of the guide member 11 on the guide frame 12, but also prevents the guide member 11 from falling out of the clamp groove 1211 of the guide frame 12, and also facilitates maintenance personnel to replace corresponding components during maintenance.

[0059] Preferably, the weight body 21 is cylindrical, the guide member 11 is a circular ring structure, the clamp groove 1211 of the guide frame 12 is semicircular, the blocking member 22 is disc-shaped, and the outer diameter of the outer edge 221 of the blocking member 22 is larger than the inner diameter of the inner wall 111 of the guide member 11.

[0060] For easy understanding, please refer to Figures 2 to 5 and Figure 8 、 Figure 10 As shown, the weight body 21 is cylindrical and can be made directly from round steel, avoiding secondary processing. At the same time, in order to provide a better guiding function for the cylindrical weight body 21, the guide member 11 is designed as a circular ring structure. Of course, in order to provide a better clamp fixing effect for the guide member 11, the clamp groove 1211 of the guide frame 12 is also designed as a semi-circular clamp groove 1211. Specifically, the clamp groove 1211 has a semi-circular semi-circular groove 1212 and a pair of clamp legs 1213 formed circumferentially from both ends of the semi-circular groove 1212. In order to ensure that the guide member 11 can support the blocking member 22 in the event of a break in the wire rope 3, the blocking member 22 is provided in a disc shape, and the outer diameter of its outer edge 221 is larger than the inner diameter of the inner wall 111 of the guide member 11. Of course, in order to achieve the best supporting effect, the outer diameter of the outer edge 221 of the blocking member 22 can be set to be larger than the outer diameter of the outer wall 112 of the guide member 11.

[0061] Furthermore, at least two guide assemblies 1 are provided, and each guide assembly 1 is separated and arranged in the vertical direction.

[0062] For easy understanding, please refer to Figure 2 As shown, the guide assembly 1 can be provided in a plurality, each guide assembly 1 having a guide member 11 and a guide frame 12, and the guide assemblies 1 are separated in the vertical direction. The plurality of guide assemblies 1 separated in the vertical direction can not only limit the shaking of the weight body 21 when it moves up and down, but also prevent the weight body 21 from continuing to fall when one of the guide assemblies 1 fails. Preferably, the guide assemblies 1 can be provided in two, which is not specifically limited in this embodiment.

[0063] Furthermore, the guide member 11 is made of a soft material, and the guide frame 12 and the blocking member 22 are made of a rigid material.

[0064] As is easy to understand, the guide member 11 is made of a soft material, such as polyurethane, nylon, rubber, Teflon, etc. The guide frame 12 and the blocking member 22 are made of a rigid material, such as ordinary carbon steel, such as Q235 steel. This embodiment allows the blocking member 22 to be supported by the guide member 11 in the event that the wire rope 3 pulling the weight body 21 breaks. At this time, the rigid blocking member 22 will drag the weight body 21 under the support of the guide member 11, and the rigid blocking member 22 will not deform. Furthermore, when the blocking member 22 falls onto the guide member 11, the soft guide member 11 will have a better cushioning function and will not cause permanent damage to the guide member 11 itself and the blocking member 22. The guide member 12 is made of a rigid material, which can better hold the guide member 11 and ensure that the guide member 11 and the blocking member 22 do not fall synchronously when the guide member 11 is impacted by the falling impact of the blocking member 22.

[0065] It should also be noted that the blocking member 22 can be configured to be formed by stacking multiple gaskets, such as two circular gaskets stacked in the up and down directions to form the blocking member 22, so that the blocking member 22 as a whole has better rigidity to better drag the heavy hammer body 21 when the wire rope 3 breaks.

[0066] Furthermore, the weight body 21 and the blocking member 22 are formed separately and then assembled into one body, or the weight body 21 and the blocking member 22 are formed in one body.

[0067] For easy understanding, please refer to Figure 2 As shown, after the weight body 21 and the blocking member 22 are separately formed, the blocking member 22 is mounted on the end of the weight body 21. Specifically, a threaded hole is provided at the end of the weight body 21, and one end of the wire rope 3 is connected to a threaded rod. The threaded rod passes through the blocking member 22 and is threadedly connected to the threaded hole of the weight body 21 and fastened by a fastener, so that one end of the wire rope 3 is connected to the weight body 21, and the blocking member 22 is fixed to the end of the weight body 21. Of course, in other embodiments, the weight body 21 and the blocking member 22 can be integrally formed, and specifically, the blocking member 22 can be integrally formed at the end of the weight body 21.

[0068] Furthermore, the elevator landing door system includes a landing door device 4 , a sill 5 and a fixing rod 6 connected between the landing door device 4 and the sill 5 , and the guide frame 12 is fixed to the fixing rod 6 .

[0069] Understandable, please refer to Figure 1As shown, the elevator landing door system includes a landing door device 4 disposed at the top, a sill 5 disposed at the bottom, and a fixing rod 6 connected between the landing door device 4 and the sill 5. The fixing rod 6 can be directly connected to the landing door device 4 and the sill 5, or can be indirectly connected and fixed to the landing door device 4 and the sill 5 via an adapter. By fixing the guide frame 12 to the fixing rod 6, the elevator landing door hammer assembly is installed and fixed to the elevator landing door system, thereby realizing the self-closing function of the elevator landing door hammer assembly on the elevator landing door door panel. Specifically, the guide frame 12 can be fixed to the fixing rod 6 by bolts, which is not specifically limited in this embodiment.

[0070] Furthermore, the floor door device 4 includes a door frame 41 and two hanging plates 42 installed on the door frame 41, the floor door weight 2 and one of the two hanging plates 42 are located on the same side, one end of the wire rope 3 is connected to the floor door weight 2, and the other end is connected to the hanging plate 42 located on the other side of the floor door weight 2.
