Description

Technical Field

[0001] This application relates to the technical field of fixing devices for elevator backpack frames and shaft sealing plates, and in particular to a structure for maintaining a constant distance between a platform elevator backpack frame and a shaft sealing plate. Background Technology

[0002] In existing platform elevator structures, to enhance the aesthetics of the elevator interior, a shaft sealing plate is typically added to the side of the shaft cavity near the traction machine, ensuring that users cannot see the shaft components when on the platform. However, many shaft sealing plate structures on the market focus on making the sealing plate more robust and preventing it from wobbling. For example, adding connectors to the shaft sealing plate columns at the upper and lower shaft ends, or adding vertical reinforcing ribs to the sealing plate, etc. However, in actual project applications, due to the extremely high shaft height, even if the shaft sealing plate columns are tightly connected to the upper and lower shafts, if the middle shaft sealing plate is not securely connected to the shaft, the sealing plate will inevitably wobble, causing scratches and noise, and may even lead to elevator accidents.

[0003] In view of this, this application aims to develop a structure that can maintain a constant distance between the shaft sealing plate and the backpack frame, and between the shaft sealing plate and the bottom of the car, even when the shaft sealing plate shakes greatly, thereby achieving the effect of low elevator noise and no scratching. Summary of the Invention

[0004] The technical problem this application aims to solve is that common sealing plate fixing solutions on the market only tighten the upper and lower ends of the sealing plate column, which does not actually solve the shaking problem. There is a lack of technical solutions specifically designed to ensure that the distance between the backpack frame and the sealing plate, and between the sealing plate and the bottom of the car remains unchanged when shaking is inevitable.

[0005] To solve the above-mentioned technical problems, this application provides a structure for maintaining a constant distance between a backpack frame and a shaft sealing plate in a platform elevator, comprising: a backpack frame fixed to the back of the car, with symmetrically arranged ends on the side of the backpack frame away from the car and movably connected to the car guide rail; the two ends of the backpack frame facing the car suspended behind the car; a backpack frame column perpendicular to the back of the car on the backpack frame, and a roller assembly and a fixing assembly on the backpack frame column; and a shaft sealing plate, fixed to the elevator shaft on both sides by the roller assembly and the fixing assembly.

[0006] The roller assembly includes a mounting base, a first roller, a second roller, and a third roller. The mounting base is a U-shaped groove. The first roller is mounted on one side of the U-shaped groove via angle steel. The second and third rollers are arranged side by side on the bottom side of the U-shaped groove. The extended surface of the bottom side of the U-shaped groove is tangent to the first roller, and the first roller is located on the longitudinal central axis surface between the second and third rollers. The mounting base is mounted on the backpack frame upright.

[0007] The fixing components include a sealing plate fixing post, a mounting bracket, and a baffle. The sealing plate fixing post is fixed to the mounting bracket. The main body of the sealing plate fixing post is cubic and has several connecting strip mounting slots running through it. The connecting strip mounting slots are open on both sides of the main body of the sealing plate fixing post, and the openings are sealed by the baffle. The upper end of the sealing plate fixing post is a rectangular body extending outward on one side. The extended end of the rectangular body contacts the first roller, the second roller, and the third roller. The contact points of the rectangular body with the first roller, the second roller, and the third roller are connected to form an isosceles triangle. The lower end of the sealing plate fixing post has a sealing plate mounting slot parallel to the rectangular body for inserting and fixing the side of the wellbore sealing plate. The mounting bracket is fixed to the backpack frame column and supports the sealing plate fixing post extending towards the bottom side of the U-shaped groove. The upper and lower sealing plate fixing posts located on the same side of the wellbore sealing plate are connected and fixed by connecting strips. The shapes of the two ends of the connecting strips are adapted to the connecting strip mounting slots.

[0008] According to an embodiment of this application, the backpack frame column is... The backpack frame column is movable to the car guide rail via a connector at the top, and fixed to the car via a backpack frame base at the bottom.

[0009] According to an embodiment of this application, the car guide rail is fixed inside the hoistway.

[0010] According to an embodiment of this application, the lower end of the sealing plate fixing post is also provided with an outward-facing light strip mounting groove.

[0011] According to an embodiment of this application, the traction machine is rigidly connected to the main shaft of the backpack frame via an output shaft, thereby driving the backpack frame to move up and down.

[0012] According to an embodiment of this application, the first roller is fixed to the angle steel via an axle, and the second and third rollers are also fixed to the bottom outer side of the U-shaped channel via an axle.

[0013] According to an embodiment of this application, a shaft sealing plate is installed between the traction machine and the protective backpack frame to cover the traction machine and shaft components.

[0014] According to an embodiment of this application, backpack frame columns are symmetrically arranged on the left and right sides of the backpack frame, and a connecting rod is provided between the backpack frame columns. Springs are sleeved at the connection points between the two ends of the connecting rod and the backpack frame columns.

[0015] According to an embodiment of this application, the connecting strip is provided with a plurality of mounting holes evenly distributed.

[0016] According to an embodiment of this application, the angle steel is welded and fixed to the U-shaped channel.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0018] 1. The platform elevator forms a dynamic limiting system through the three-point rolling cooperation between the backpack frame rollers and the contact surface of the sealing plate fixing column. During the operation of the elevator, a constant distance is forcibly maintained between the shaft sealing plate and the backpack frame (and the car), thereby effectively solving the safety hazards that may be caused by the shaking of the sealing plate and realizing a simple, safe and reliable constant distance maintenance mechanism.

[0019] 2. The sealing plate fixing column used in this application has a rectangular body at the upper end that contacts the roller of the backpack frame, forming a three-point rolling engagement with the contact surface, which ensures smooth operation. The rolling contact between the roller and the contact surface reduces friction and vibration, improving ride comfort. The sealing plate fixing column has a sealing plate mounting groove at the lower end to fix the side of the shaft sealing plate, preventing interference or collision with moving parts (such as the backpack frame or car) due to the shaking of the sealing plate, thus improving safety.

[0032] like Figures 1 to 6 As shown in the example of this application, a structure for maintaining a constant distance between a platform elevator backpack frame and a shaft sealing plate includes a backpack frame 10 and a shaft sealing plate 3 installed between the traction machine 1 and the backpack frame 10. Roller assemblies 11 and fixing assemblies 12 are fixedly installed on the backpack frame column 13 of the backpack frame 10. The left and right sides of the shaft sealing plate 3 are fixed to the backpack frame 10 through the roller assemblies 11 and fixing assemblies 12. This achieves a constant distance between the backpack frame 10 and the shaft sealing plate 3, and between the car bottom and the shaft sealing plate 3, when the shaft sealing plate 3 shakes. This results in low elevator noise and no scraping between moving parts, solving the problem of shaft sealing plate 3 shaking that cannot be effectively solved in the prior art.

[0033] In this embodiment, as Figure 1 , Figure 2As shown, the backpack rack 10 is fixed to the back of the car 4. The two ends of the backpack rack 10 on the side away from the car 4 are symmetrically arranged and movably connected to the car guide rail 2. The two ends of the backpack rack 10 on the side facing the car 4 are suspended behind the car 4. The backpack rack 10 is provided with a backpack rack column 13 perpendicular to the back of the car 4. The backpack rack column 13 is provided with a roller assembly 11 and a fixing assembly 12.

[0034] Specifically, the car guide rail 2 is fixed inside the hoistway to provide guidance for the backpack frame 10 and ensure the stable running trajectory of the backpack frame 10.

[0035] Specifically, the traction machine 1 is rigidly connected to the main shaft of the backpack frame 10 through the output shaft, thereby driving the backpack frame 10 to move up and down.

[0036] Specifically, such as Figure 2 , Figure 3 As shown, the backpack frame 10 includes backpack frame uprights 13, roller assembly 11, and backpack frame base 14. The backpack frame uprights 13 are symmetrically arranged on the left and right sides of the backpack frame 10. A connecting rod 5 is provided between the backpack frame uprights 13, and springs 51 are fitted at the connection points between the two ends of the connecting rod 5 and the backpack frame uprights 13. The backpack frame uprights 13 are... The backpack frame column 13 is movably connected to the car guide rail 2 via a connector at its upper end, and is fixedly connected to the car 4 via a backpack frame base 14 at its lower end.

[0037] In this embodiment, the left and right sides of the shaft sealing plate 3 are fixed to the elevator shaft by roller assembly 11 and fixing assembly 12.

[0038] Specifically, the shaft sealing plate 3 is installed between the traction machine 1 and the protective backpack frame 10 to cover the traction machine 1 and the shaft components.

[0039] Specifically, the shaft sealing plate 3 is fixed in the shaft by the sealing plate fixing column 121. The sealing plate fixing column 121 is provided with roller contact surface, and there are three contact surfaces in total, forming a dynamic limit system. During the operation of the elevator, a constant distance is forcibly maintained between the shaft sealing plate 3 and the backpack frame 10 (and the car 4), thereby effectively solving the safety hazards that may be caused by the shaking of the sealing plate and realizing a simple, safe and reliable constant distance maintenance mechanism.

[0040] In this embodiment, as Figure 4As shown, the roller assembly 11 includes a mounting base 114, a first roller 111, a second roller 112, and a third roller 113. The mounting base 114 is a U-shaped groove. The first roller 111 is mounted on one side of the U-shaped groove by an angle steel 115. The second roller 112 and the third roller 113 are arranged side by side on the bottom side of the U-shaped groove. The extended surface of the bottom side of the U-shaped groove is tangent to the first roller 111, and the first roller 111 is located on the longitudinal central axis surface between the second roller 112 and the third roller 113.

[0041] Specifically, the mounting base 114 is fixedly installed on the backpack frame column 13, that is, the three rollers move up and down along the car guide rail 2 together with the backpack frame 10.

[0042] In this embodiment, as Figure 5 As shown, the fixing assembly 12 includes a sealing plate fixing post 121, a mounting bracket 122, and a baffle 123. The sealing plate fixing post 121 is fixed on the mounting bracket 122. The main body of the sealing plate fixing post 121 is cubic and has several connecting strip mounting grooves 1212 extending through it. The connecting strip mounting grooves 1212 are open on both sides of the main body of the sealing plate fixing post 121, and the openings are sealed by the baffle 123. The upper end of the sealing plate fixing post 121 is a rectangular body 1211 extending outward on one side. The extended end of the rectangular body 1211 connects with the first roller. 111. The second roller 112 and the third roller 113 are in contact. The rectangular body 1211 is connected to the contact point of the first roller 111, the second roller 112 and the third roller 113 to form an isosceles triangle. The backpack frame roller and the contact surface of the rectangular body 1211 extending outward from the sealing plate fixing post 121 form a three-point rolling fit, forming a dynamic limiting system. The lower end of the sealing plate fixing post 121 is provided with a sealing plate mounting groove 1213 parallel to the rectangular body 1211 for inserting and fixing the side of the well sealing plate 3.

[0043] Specifically, the first roller 111 is fixed to the angle steel 115 via an axle, and the second roller 112 and the third roller 113 are also fixed to the bottom outer side of the U-shaped channel via an axle.

[0044] Specifically, angle steel 115 is welded and fixed to the U-shaped channel.

[0045] Specifically, the mounting bracket 122 is fixed to the backpack frame column 13. The mounting bracket 122 carries the sealing plate fixing column 121 extending to the bottom side of the U-shaped groove of the roller assembly 11. That is, the side of the mounting base 114 with two rollers faces the fixing assembly 12, so that the rectangular body 1211 of the sealing plate fixing column 121 can contact the three rollers.

[0046] Specifically, multiple sets of fixing components 12 can be symmetrically arranged on the left and right sides of the wellbore sealing plate 3. The side of the wellbore sealing plate 3 is inserted into the sealing plate mounting groove 1213 of the sealing plate fixing post 121 for fixing. The upper and lower sealing plate fixing posts 121 located on the same side of the wellbore sealing plate 3 are connected and fixed by a connecting strip 15. The shape of both ends of the connecting strip 15 is adapted to the connecting strip mounting groove 1212.

[0047] Specifically, the lower end of the sealing plate fixing post 121 is also provided with an outward-facing light strip mounting groove 1214.

[0048] Specifically, the sealing plate fixing post 121, the light strip mounting groove 1214, and the sealing plate mounting groove 1213 can be integrally formed.

[0049] Specifically, the connecting strip 15 is provided with multiple mounting holes evenly distributed.

[0050] In this embodiment, the working principle of the structure used to maintain a constant distance between the backpack frame 10 and the shaft sealing plate 3 in the platform elevator is as follows: Guiding and limiting: The backpack frame 10 is guided by the car guide rail 2 and moves up and down along the guide rail during elevator operation. Since the guide rail is fixed, the lateral and vertical distances between the backpack frame 10 and the shaft remain basically unchanged; Roller and contact surface cooperation: The three rollers on the backpack frame 10 are always in contact with the three roller contact surfaces on the sealing plate fixing column 121. This three-point contact structure forms a stable limiting system, restricting the lateral and longitudinal displacement of the backpack frame 10 relative to the sealing plate fixing column 121; Maintaining a constant distance: Even if the shaft sealing plate 3 shakes slightly due to installation or force, the relative position between the backpack frame 10 and the shaft sealing plate 3 is strictly limited because the rollers are always in close contact with the contact surface of the sealing plate fixing column 121. Therefore, no matter what height the elevator runs to, the distance between the shaft sealing plate 3 and the backpack frame 10, and between the shaft sealing plate 3 and the car 4, remains constant.

[0051] In summary, the technical solution of this application has the following beneficial effects:

[0052] 1. The platform elevator forms a dynamic limiting system through the three-point rolling cooperation between the backpack frame rollers and the contact surface of the sealing plate fixing column. During the operation of the elevator, a constant distance is forcibly maintained between the shaft sealing plate and the backpack frame (and the car), thereby effectively solving the safety hazards that may be caused by the shaking of the sealing plate and realizing a simple, safe and reliable constant distance maintenance mechanism.

[0053] 2. The sealing plate fixing column used in this application has a rectangular body at the upper end that contacts the roller of the backpack frame, forming a three-point rolling engagement with the contact surface, which ensures smooth operation. The rolling contact between the roller and the contact surface reduces friction and vibration, improving ride comfort. The sealing plate fixing column has a sealing plate mounting groove at the lower end to fix the side of the shaft sealing plate, preventing interference or collision with moving parts (such as the backpack frame or car) due to the shaking of the sealing plate, thus improving safety.

[0054] 3. The backpack frame structure used in this application integrates a roller system and a fixing system, eliminating the need for additional complex devices and saving shaft space.
