Description

Technical Field

[0001] The utility model relates to the technical field of elevator accessories, in particular to an elevator door hanging plate guide rail structure. Background Art

[0002] The elevator door system includes the floor door system and the car door system. The floor door system corresponds to the floor station entrance and exit. The floor door is passively opened and closed under the drive of the car door. The floor door system includes the upper sill assembly, door panel and door frame. The upper sill assembly is composed of the door head panel, door hanging panel, door pulley, door guide rail and other components. The door hanging panel is suspended on the door guide rail by the door pulley and moves under the guidance of the door guide rail to drive the door panel to open and close.

[0003] In the existing technology, many companies build their factories into multi-story buildings to transport large-sized goods. At this time, they need to use stronger elevators to prevent the door panels from running poorly. When transporting large-sized goods, they need to use larger and taller elevators to avoid collisions that cause the doors to slide off the door guides, resulting in the door hanging panels falling off, thus causing safety accidents. Utility Model Content

[0004] The utility model aims to provide an elevator door hanging plate guide rail structure which has higher strength and anti-collision effect.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] An elevator door hanging plate guide rail structure comprises a guide rail base and a door hanging plate, wherein guide rail groups are fixedly installed on the upper and lower sides of the guide rail base through grooves, an arc-shaped bar is installed on the upper end of the guide rail group, and a rectangular bar is installed on the lower end of the guide rail group; two upper and lower sliding groups are arranged on the door hanging plate, and the door hanging plate is slidably installed on two arc-shaped bars through the two sliding groups; two upper and lower protection groups A are arranged on the door hanging plate, and the door hanging plate is slidably installed on two rectangular bars through the two protection groups A; a protection group B is arranged on the guide rail base, and the protection group B is located between the two guide rail groups, and the protection group B is used for stabilizing the door hanging plate on the first layer.

[0007] It can be seen that the coordinated use of the guide rail base and the two guide rail groups can increase the strength of the guide rail and make it more suitable for transporting large-sized goods. The guide rail group installed through the groove can not only reduce the material and weight, so that the guide rail does not need to be restricted by the mold or specific processing equipment, but also increase the elastic deformation capacity of the guide rail group to prevent the guide rail group from being broken due to local force. During the sliding process, the protection group A and the protection group B can play a double-layer limiting role on the door hanging plate to prevent the goods from hitting the door hanging plate when transporting large-sized goods, causing the pulley to fall off the guide rail group, thereby avoiding the door hanging plate from falling off the guide rail group. The double-layer protection makes the overall stability stronger, improves the impact resistance of the door hanging plate, and reduces the possibility of safety accidents.

[0008] Furthermore, the sliding group includes a pulley, a connecting plate, a screw and a fastener, and two groups of mounting holes A are opened on the door hanging plate; the pulley is slidably installed on the arc bar, and a connecting plate is installed on the side of the pulley close to the door hanging plate; the screw is fixedly connected to the connecting plate by passing through the mounting hole A, and the screw and the door hanging plate are fixed by fasteners.

[0009] When the elevator door system is started, the pulley is driven to slide on the arc bar, thereby driving the door hanging plate to move synchronously, so that the door hanging plate can be guided to move under the action of the guide rail group. By using two sets of sliding groups, the door hanging plate can be guided to slide on the two sets of guide rail groups, which can increase the strength of the guide rails, improve the bearing capacity of the elevator, and be more suitable for transporting large-sized goods.

[0010] Furthermore, the protection group A includes a U-shaped block, a slider and a fastening bolt. A sliding groove is opened on the rectangular bar, and two sets of mounting holes B are installed on the door hanging plate; the U-shaped block and the slider are not fixedly connected, and the slider is slidably installed in the sliding groove; the fastening bolt passes through the mounting hole B and penetrates the door hanging plate to connect with the U-shaped block.

[0011] In specific operations, since the U-shaped block is connected to the door hanging plate by fastening bolts, it drives the U-shaped block to slide on the slide groove, providing stability for the movement of the door hanging plate, avoiding the door hanging plate from being hit and causing the pulley to fall off the arc bar when transporting large-sized goods, resulting in safety accidents, thereby improving the stability of the door hanging plate.

[0012] Furthermore, the protection group B includes a mounting part A, a sliding rod, a mounting part B and a mounting block; the sliding rod is fixedly installed at the center position of the left and right sides of the guide rail base through the mounting part A, and two groups of mounting blocks are installed at the center position of one side of the door hanging plate close to the guide rail base through the mounting part B; the two mounting blocks are slidably installed on the sliding rod through the sliding hole.

[0013] During the sliding process of the door hanging plate, it can drive the mounting block to slide on the sliding rod through the sliding hole, providing a second layer of stability for the sliding of the door hanging plate, avoiding the pulley from sliding off the arc bar due to impact, preventing the door hanging plate from derailing, further improving the carrying capacity when transporting large-sized goods, and providing higher safety.

[0014] Furthermore, a sponge pad is installed on the inner wall of the slide groove.

[0015] The sponge pad can improve the interactive friction of the U-shaped block in the slide groove, avoid the phenomenon that the U-shaped block is separated from the slide groove when hitting the door hanging plate, and improve the anti-separation performance of the door hanging plate.

DETAILED DESCRIPTION

[0021] The utility model is described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-4 As shown, an elevator door hanging plate guide rail structure includes a guide rail base 1 and a door hanging plate 3, wherein guide rail groups 2 are fixedly installed on the upper and lower sides of the guide rail base 1 through grooves, an arc strip 21 is installed on the upper end of the guide rail group 2, and a rectangular strip 22 is installed on the lower end of the guide rail group 2; two upper and lower sliding groups 4 are arranged on the door hanging plate 3, and the door hanging plate 3 is slidably installed on the two arc strips 21 through the two sliding groups 4; two upper and lower protection groups A5 are arranged on the door hanging plate 3, and the door hanging plate 3 is slidably installed on the two rectangular strips 22 through the two protection groups A5; a protection group B6 is arranged on the guide rail base 1, and the protection group B6 is located between the two guide rail groups 2, and the protection group B6 is used to stabilize the door hanging plate 3 on the first layer.

[0023] During specific use, the door hanging plate 3 is preliminarily made to slide on the two guide rail groups 2 by using the sliding group 4. The coordinated use of the guide rail base 1 and the two guide rail groups 2 can improve the strength of the guide rails. The guide rail groups 2 installed through the grooves can reduce the material and weight. During the sliding process, the protection group A5 and the protection group B6 can play a double-layer limiting role on the door hanging plate 3 to prevent the goods from hitting the door hanging plate 3 when transporting large-sized goods, causing the pulley 41 to fall off the guide rail group 2, thereby avoiding the door hanging plate 3 from falling off the guide rail group 2.

[0024] Specifically, the sliding group 4 includes a pulley 41, a connecting plate 42, a screw 43 and a fastener 44. Two groups of mounting holes A401 are provided on the door hanging plate 3. The pulley 41 is slidably mounted on the arc strip 21. A connecting plate 42 is mounted on the side of the pulley 41 close to the door hanging plate 3. The screw 43 is fixedly connected to the connecting plate 42 through the mounting hole A401. The screw 43 is fixed to the door hanging plate 3 by the fastener 44. When the elevator door system is started, the pulley 41 is driven to slide on the arc strip 21. Since the pulley 41 is connected to the door hanging plate 3 through the connecting plate 42 and the screw 43, and the screw 43 and the door hanging plate 3 are fixed by the fastener 44, the sliding pulley 41 can drive the door hanging plate 3 to move synchronously, thereby realizing the guided movement of the door hanging plate 3 under the action of the guide rail group 2. By using two groups of sliding groups 4, the door hanging plate 3 can be guided and slid on the two groups of guide rail groups 2.

[0025] Specifically, the protection group A5 includes a U-shaped block 51, a slider 52 and a fastening bolt 53. A slide groove 501 is provided on the rectangular bar 22, and two groups of mounting holes B502 are installed on the door hanging plate 3. The U-shaped block 51 and the slider 52 are not fixedly connected, and the slider 52 is slidably installed in the slide groove 501. The fastening bolt 53 passes through the door hanging plate 3 through the mounting hole B502 and is connected to the U-shaped block 51. The U-shaped block 51 and the slider 52 are fixedly connected to make the connectivity and stability stronger. In specific operation, when the door hanging plate 3 slides on the two guide rail groups 2 through the sliding group 4, since the U-shaped block 51 is connected to the door hanging plate 3 through the fastening bolt 53, it can drive the U-shaped block 51 to slide on the slide groove 501, providing a stabilizing effect for the movement of the door hanging plate 3, and preventing the door hanging plate 3 from being hit and causing the pulley 41 to fall off the arc bar 21 when transporting large-sized goods.

[0026] Specifically, the protection group B6 includes a mounting member A61, a slide bar 62, a mounting member B63 and a mounting block 64; the slide bar 62 is fixedly mounted at the center of the left and right sides of the guide rail base 1 through the mounting member A61, and two groups of mounting blocks 64 are mounted at the center of one side of the door hanging plate 3 close to the guide rail base 1 through the mounting member B63; the two mounting blocks 64 are slidably mounted on the slide bar 62 through the sliding hole. During the sliding process of the door hanging plate 3, the mounting block 64 can be driven to slide on the slide bar 62 through the sliding hole, providing a second layer of stabilization effect for the sliding of the door hanging plate 3, and preventing the pulley 41 from sliding off the arc strip 21 due to collision.

[0027] Specifically, a sponge pad is installed on the inner wall of the slide groove 501. By arranging the sponge pad in the slide groove 501, the interactive friction of the U-shaped block 51 in the slide groove 501 can be increased, and the phenomenon that the U-shaped block 51 is separated from the slide groove 501 when hitting the door hanging plate 3 can be avoided.
