Description

Technical Field

[0001] The present application relates to the technical field of elevators, and in particular to an installation device for an elevator hanging plate wheel. Background Art

[0002] At present, during the use of elevators, due to long-term opening and closing of doors, the hanging plate wheels of elevator car doors and floor doors will be worn or damaged, so they need to be repaired and replaced regularly. The traditional method of replacing the hanging plate wheels is to first clamp the hanging plate wheels on the hanging plate shaft rod, and then use a hammer to knock the hanging plate wheels completely into the hanging plate shaft rod, thereby realizing the replacement and installation of the hanging plate wheels on the hanging plate.

[0003] According to the above operation, directly using a hammer to hit the hanging plate wheel can easily cause damage to the surface of the hanging plate wheel, and even damage the bearings of the hanging plate wheel, shortening the service life of the hanging plate wheel. There is room for improvement. Utility Model Content

[0004] In order to reduce damage to the hanging plate wheel when replacing the hanging plate wheel, the present application provides an installation device for the elevator hanging plate wheel.

[0005] The present application provides an installation device for an elevator hanging plate wheel, which adopts the following technical solution:

[0006] A device for installing an elevator hanging plate wheel comprises a frame, on which are arranged, from top to bottom, a blocking mechanism for limiting the position of the hanging plate wheel, a lifting head abutting against the side of the hanging plate facing away from the blocking mechanism, and a pressing mechanism for pressing the hanging plate; a placement space for placing the hanging plate and the hanging plate wheel is provided between the blocking mechanism and the lifting head; the lifting head is mounted on the pressing mechanism and is arranged coaxially with the blocking mechanism in the vertical direction.

[0007] By adopting the above technical solution, in actual operation, the hanging plate is lifted in the vertical direction by utilizing the setting of the pressing mechanism and the lifting head, and at the same time, the blocking mechanism coaxially arranged with the lifting head is utilized to limit the position of the hanging plate wheel to remain stationary when the lifting head presses the hanging plate. As the lifting head continues to press the hanging plate, the force is applied to the side of the hanging plate away from the blocking mechanism. As the height of the hanging plate relative to the hanging plate wheel is lifted, the hanging plate shaft rod is brought into contact with the blocking mechanism, and then the hanging plate wheel is completely installed on the hanging plate shaft rod, which has the advantages of easy installation, reduced loss cost, and improved installation efficiency and safety.

[0008] Preferably, the blocking mechanism includes an external pressure head and a fixing nut, the external pressure head passes through the frame and is threadedly connected to the fixing nut, and the fixing nut forms an abutment fit with the frame on a side close to the external pressure head.

[0009] By adopting the above technical solution, the external pressure head is threadedly connected to the frame, so that the fixed connection between the external pressure head and the frame is detachable, which is convenient for the staff to replace the external pressure head.

[0010] Preferably, a handheld concave surface is provided on the outer wall of the external pressure head.

[0011] By adopting the above technical solution, by using the handheld concave surface provided on the outer wall of the external pressure head, it is convenient for the staff to hold the external pressure head by hand, reducing the risk of the external pressure head falling down during the installation and disassembly process, and thus damaging the external pressure head or other components.

[0012] Preferably, a profiling groove matching the outer contour of the hanging plate wheel is provided on one side of the external pressure head close to the lifting head.

[0013] By adopting the above technical solution, by using the design of the profiling groove on the external pressure head, the hanging plate wheel can be adapted to the profiling groove during the installation process, thereby ensuring that the position of the hanging plate wheel is more firmly limited by the profiling groove.

[0014] Preferably, the blocking mechanism includes an elastic member and an inner shaft. A stepped surface is provided on the inner shaft. The external pressure head is provided with an embedding groove matching the outer contours of the elastic member and the inner shaft. The opening of the embedding groove faces downward. The upper end of the elastic member abuts against the top of the embedding groove, and the lower end of the elastic member abuts against the stepped surface of the inner shaft. The inner shaft is symmetrically provided with limiting grooves in the radial direction. Upper and lower retaining edges are respectively provided in the limiting grooves of the inner shaft. A blocking member is horizontally arranged in the embedding groove of the external pressure head, and the blocking member is located in the limiting groove.

[0015] By adopting the above technical solution, by using the two ends of the elastic member to abut against the external pressure head and the inner shaft respectively, when the inner shaft is stressed, the elastic member provides a certain buffering force, reducing the risk of damaging the inner shaft due to excessive force during the pressing process, thereby protecting the hanging plate shaft rod; by using the arrangement of the blocking member and the limiting groove, the inner shaft is blocked by the blocking member and will not fall down.

[0016] Preferably, a plug board is inserted and matched with the external pressure head. The blocking member is arranged on the plug board. The plug board and the limiting groove form an embedded sliding fit. One side of the plug board away from the inner shaft is connected to the external pressure head by a plug pin.

[0017] By adopting the above technical solution, the insert plate and the limit groove are embedded and slidingly matched, and the upper and lower ribs are set in the limit groove, so that the buffering range of the elastic member is limited to the height distance of the limit groove, that is, the inner shaft can only slide up and down within the height range of the limit groove. At the same time, the insert plate is plugged in with the external pressure head to achieve the detachability of the insert plate relative to the external pressure head, and the side of the insert plate away from the inner shaft is connected to the external pressure head pin to further fix the insert plate and the external pressure head, thereby ensuring the stability of the insert plate.

[0018] Preferably, the frame is provided with a support plate for supporting the hanging plate, and a second avoidance space for avoiding the lifting of the lifting head is provided between the support plate and the lifting head.

[0019] By adopting the above technical solution and utilizing the design of the support plate, a stable support platform is provided for the hanging plate, reducing the risk of the hanging plate slipping due to instability during installation. At the same time, the setting of the second avoidance space can avoid the rise of the lifting head, reducing the risk of collision between the lifting head and the support plate.

[0020] Preferably, the support plate is provided with an adapting hole along its thickness direction, the lifting head is fitted with the adapting hole, and the second avoidance space is formed in the adapting hole.

[0021] By adopting the above technical solution and utilizing the setting of the adapter hole, it is convenient for the lifting head to pass through the adapter hole on the support plate, thereby smoothly pressing the hanging plate and improving the stability during the installation process.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. During actual operation, the hanging plate is lifted vertically by utilizing the pressing mechanism and the lifting head. At the same time, a blocking mechanism coaxially arranged with the lifting head is utilized to limit the position of the hanging plate wheel to remain stationary when the lifting head presses the hanging plate. As the lifting head continues to press the hanging plate, a force is applied to the side of the hanging plate away from the blocking mechanism. As the height of the hanging plate relative to the hanging plate wheel is raised, the hanging plate shaft rod abuts and cooperates with the blocking mechanism, and the hanging plate wheel is smoothly and completely installed on the hanging plate shaft rod. This has the advantages of convenient installation, reduced loss cost, and improved installation efficiency and safety.

[0024] 2. The combined design of the elastic member, blocking member, limiting slot, and insert plate allows for a certain elastic buffer zone for the inner shaft when the external pressure head is under pressure, through the elastic force range of the elastic member and the sliding range of the limiting slot. This reduces the risk of damage to the hanging plate shaft due to excessive pressure and violent collision with the inner shaft.

[0025] 3. Combining the design of the support plate and the adapter hole, while the support plate provides support for the hanging plate, the setting of the adapter hole makes it easier for the lifting head to pass through the adapter hole on the support plate, thereby smoothly pressing the hanging plate and improving the stability during installation.

[0032] The following is combined with Figure 1 -Attached Figure 5 This application is described in further detail.

[0033] The embodiment of the present application discloses an installation device for an elevator hanging plate wheel.

[0034] Example 1:

[0035] Reference Figure 1, An installation device for an elevator hanging plate wheel, comprising a frame 1. The frame 1 is arranged in a C-shaped structure. On the frame 1, there is a blocking mechanism 2 for defining the position of the hanging plate wheel, a lifting head 3 that abuts against the side of the hanging plate away from the blocking mechanism 2, and a pressing mechanism 4 for pressing the hanging plate. The blocking mechanism 2, the lifting head 3, and the pressing mechanism 4 are arranged in sequence from top to bottom. The lifting head 3 is in the shape of a stepped cylinder, and there is a placement space 5 for placing the hanging plate and the hanging plate wheel between the lifting head 3 and the blocking mechanism 2. On the blocking mechanism 2, there is a first avoidance space 6 for avoiding the hanging plate shaft rod during the installation process. The lifting head 3 is sleeved on the pressing mechanism 4 and is coaxially arranged with the blocking mechanism 2 in the vertical direction.

[0036] Refer to Figure 1 , During actual operation, by means of the settings of the pressing mechanism 4 and the lifting head 3, the hanging plate is lifted in the vertical direction. At the same time, by using the blocking mechanism 2 coaxially arranged with the lifting head 3, when the lifting head 3 presses the hanging plate, the position of the hanging plate wheel is restricted to remain stationary. As the lifting head 3 continuously presses the side of the hanging plate away from the blocking mechanism 2, the height of the hanging plate relative to the hanging plate wheel is continuously increased. At the same time, the gradually protruding hanging plate shaft rod is located in the first avoidance space 6, and the hanging plate presses the hanging plate wheel on the hanging plate shaft rod, so that the hanging plate wheel is completely installed on the hanging plate.

[0037] Refer to Figure 1 and Figure 2 , The frame 1 includes side plates 11 symmetrically arranged at intervals in the horizontal direction. Between the two side plates 11, there is a top plate 12 and a bottom plate 13 arranged horizontally. The bottom plate 13 is located at the bottom of the frame 1 and is fixedly welded to the pressing mechanism 4. The blocking mechanism 2 includes an outer pressing head 21 and a fixing nut. The outer pressing head 21 passes through the top plate 12 from bottom to top and is threadedly connected to the fixing nut. And the side of the fixing nut close to the outer pressing head 21 forms an abutting fit with the frame 1. The outer pressing head 21 also passes through a flat washer and an elastic washer between the top plate 12 and the fixing nut. Since the outer pressing head 21, the flat washer, and the elastic washer are all fixed on the top plate 12 by the fixing nut, the fixed connection between the outer pressing head 21 and the top plate 12 is detachable, which is convenient for the staff to replace the outer pressing head 21.

[0038] Refer to Figure 1 and Figure 2 , On the outer wall of the outer pressing head 21, there are hand-held concave surfaces 211 symmetrically arranged in the radial direction, which is convenient for the staff to hold the outer pressing head 21 by hand, reducing the risk that the outer pressing head 21 falls down due to the influence of gravity during the process of installing and disassembling the outer pressing head 21, and further damaging the outer pressing head 21 or other components; on the side of the outer pressing head 21 close to the lifting head 3, there is a profiling groove 212 that matches the outer contour of the hanging plate wheel. The stepped contour formed on the profiling groove 212 forms an abutting fit with the outer contours of the bearing and the wheel disc, so as to ensure that the profiling groove 212 more firmly defines the position of the hanging plate wheel.

[0039] Refer to Figure 3 andFigure 4 The blocking mechanism 2 includes an elastic member 22 and an inner shaft 23. A convex block 231 with a smaller diameter is integrally formed on the inner shaft 23. That is, the inner shaft 23 and the convex block 231 form a stepped shaft structure. The elastic member 22 is sleeved on the convex block 231. A stepped surface 232 is formed at the connection between the convex block 231 and the inner shaft 23. The outer pressure head 21 is provided with an embedding groove 213. The embedding groove 213 is arranged with an opening facing downwards and is matched with the outer contours of the elastic member 22 and the inner shaft 23. That is, an embedding fit is formed between the embedding groove 213 and the elastic member 22 and the inner shaft 23. The upper end of the elastic member 22 abuts against the top of the embedding groove 213, and the lower end of the elastic member 22 abuts and cooperates with the stepped surface 232 of the inner shaft 23. And a first avoidance space 6 is formed in the embedding groove 213. That is, the hanging plate shaft rod forms an embedding fit with the embedding groove 213. When the hanging plate shaft rod presses against the inner shaft 23, the elastic member 22 provides a certain buffering force to the inner shaft 23, thereby reducing the damage to the inner shaft 23 due to excessive force during the pressing process, and further protecting the hanging plate shaft rod from being damaged during the installation process. In the embodiment of the present application, the elastic member 22 is set as a compression spring.

[0040] Refer to Figure 3 and Figure 4 As shown in and, the inner shaft 23 is symmetrically provided with limiting grooves 24 along the radial direction. Upper stop edges 241 and lower stop edges 242 are respectively arranged in any one of the limiting grooves 24 of the inner shaft 23. The buffering action range of the elastic member 22 is limited to the height distance of the limiting grooves 24. That is, the inner shaft 23 can only slide up and down within the height range of the limiting grooves 24. Blocking members 251 are symmetrically arranged along the horizontal direction on the inner side of the outer pressure head 21. Any one of the blocking members 251 is located in the limiting groove 24. Thus, the inner shaft 23 is blocked by the blocking member 251 and will not fall downwards. A plugging groove 214 is opened along the horizontal direction on the outer pressure head 21. An n-shaped plug plate 25 is plugged and cooperated in the plugging groove 214 of the outer pressure head 21, so as to realize the detachable connection of the plug plate 25 relative to the outer pressure head 21. Any one of the blocking members 251 is symmetrically arranged on the plug plate 25 and is on both sides where the openings of the plug plate 25 are close to each other. That is, both sides of the opening of the plug plate 25 respectively form an embedding and sliding fit with the two limiting grooves 24.

[0041] Refer to Figure 3 and Figure 4, on the side of the plug board 25 away from the inner shaft 23, there is a pin hole 252. The outer pressure head 21 is located in the profiling groove 212, and a positioning groove 215 and a threaded groove 216 are successively opened from bottom to top. The positioning groove 215, the pin hole 252, and the threaded groove 216 are successively connected and communicated. During actual use, the operator can pass the plug-in bolt through the positioning groove 215 and the pin hole 252 in sequence and thread it into the threaded groove 216 to fix the plug board 25. This improves the connection stability between the plug board 25 and the outer pressure head 21. When the outer pressure head 21 is under pressure, within the elastic force range of the elastic member 22 and the sliding range of the limiting groove 24, the inner shaft 23 has a certain elastic buffer range, thereby reducing the risk of the hanging board shaft rod being damaged due to excessive top pressure and severe collision with the inner shaft.

[0042] The implementation principle of the embodiment of the present application is as follows: During actual operation, first, the hanging board wheel to be replaced is clamped on the hanging board shaft rod of the hanging board, and then the hanging board is placed in the placement space 5 between the outer pressure head 21 and the lifting head 3, and the outer pressure head 21, the hanging board wheel, and the lifting head 3 are on the same axis. During the installation process, it is necessary to ensure that the staff supports the end of the hanging board away from the installation of the hanging board wheel with their hands throughout the process, reducing the risk of the hanging board slipping due to unstable support. After ensuring the stable support of the hanging board, start the top pressure mechanism 4 to drive the lifting head 3 to slowly lift. The lifting head 3 abuts against the side of the hanging board away from the outer pressure head 21, so that the height of the hanging board relative to the hanging board wheel gradually increases. When the hanging board shaft rod is lifted to abut against the inner shaft 23, the profiling groove 212 also restricts the position of the hanging board wheel. As the lifting head 3 continuously presses the hanging board, the position of the hanging board is lifted while the position of the hanging board wheel remains unchanged, so that the hanging board wheel is successfully and completely installed on the hanging board.

[0043] Embodiment Two:

[0044] The difference between Embodiment Two and Embodiment One is as follows:

[0045] Refer to Figure 1 and Figure 5 , between the two side plates 11 of the frame 1, a support plate 14 for supporting the placement of the hanging board is fixed by bolts, providing a stable support platform for the hanging board and reducing the risk of the hanging board slipping due to unstable support during the installation process. A second avoidance space 7 is provided between the support plate 14 and the lifting head 3, and the second avoidance space 7 is used to avoid the rising of the lifting head 3, reducing the risk of collision between the lifting head and the support plate.

[0046] Refer to Figure 1 and Figure 5, a fitting hole 141 is formed through the support plate 14 in the thickness direction, a second avoidance space 7 is formed in the fitting hole 141, and the fitting hole 141 is arranged directly above the lifting head 3 and is adapted to the size of the lifting head 3, so that the lifting head 3 can pass through the fitting hole 141 during the pressing process and abut against the hanging plate on the support plate 14, improving the stability during the installation process.

[0047] During actual operation, first, the hanging plate wheel to be replaced is clamped on the hanging plate shaft rod of the hanging plate, then the hanging plate is placed on the support plate 14, and the external pressure head 21, the hanging plate wheel and the lifting head 3 are on the same axis. Although the support plate 14 provides partial support force for the hanging plate during the installation process, the staff still needs to support the end of the hanging plate far from the installation of the hanging plate wheel by hand, reducing the risk of slipping due to unstable support of the hanging plate. After ensuring the stable support of the hanging plate, start the pressing mechanism 4 to drive the lifting head 3 to slowly rise. After the lifting head 3 passes through the fitting hole 141 of the support plate 14, it abuts against the side of the hanging plate far from the external pressure head 21. Thus, the height of the hanging plate relative to the hanging plate wheel gradually rises. When the hanging plate shaft rod is raised to abut against the inner shaft 23, the profiling groove 212 also restricts the position of the hanging plate wheel. As the lifting head 3 continuously presses the hanging plate, the position of the hanging plate is raised while the position of the hanging plate wheel remains unchanged. Thus, the hanging plate wheel is successfully and completely installed on the hanging plate, having the advantages of convenient installation, reduced loss cost, improved installation efficiency and safety.

[0048] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
