Description
Technical Field
[0001] The utility model belongs to the field of elevator car tops, and in particular relates to an elevator car top fixing structure. Background Art
[0002] An elevator is a permanent transportation device that serves several specific floors in a building and whose car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or inclined at an angle of less than 15° to the plumb line. The elevator car roof is the main component of the car, located at the top of the car. The car is a box-shaped space used by the elevator to carry and transport people and materials. In addition to the elevator car roof, the car also includes car walls, car bottoms, and car doors. At present, when the top of the elevator car is connected and fixed to the suspension wire assembly, it is usually connected by bolts. Publication No. CN220519881U discloses an elevator car top fixing structure, including an elevator car, a mounting seat is fixed on the top of the elevator car, a slot is opened on the top of the mounting seat, and slots are opened on the side walls around the slot, a plug box is inserted in the slot, a suspension wire rope is fixed on the top of the plug box, a slide plate is slidably connected in the plug box, the top of the slide plate is rotatably connected to a screw rod through a bearing, the screw rod is threadedly connected to the top of the plug box, a knob is fixed on the top of the screw rod, the bottom of the slide plate is rotatably connected to four connecting rods in a circular array through pins, and the bottom ends of the four connecting rods are rotatably connected to connecting blocks through pins. During the actual use test process, we found that the elevator car fixing structure in the above-mentioned prior art still has some shortcomings. For example, the sliding of the slide is controlled by the screw rod, and then the slide rod is moved down to push the connecting rod so that the clamping rod on the connecting rod is inserted into the clamping slot of the car to fix it. First, the device is installed in the plug-in box, and the plug-in box as a whole is completely empty, and the load-bearing effect is insufficient. Secondly, the screw rod lacks a limiting structure. Once the screw rod is accidentally rotated, the plug-in box and the car top will be separated, causing the elevator to fall. Utility Model Content

[0020] The fixing mechanism 4 includes a bottom groove 406, which is provided at the lower end of the socket 3, and a shaft rod 402 is rotatably connected to the inner side of the upper end of the socket 3, and an operating head 401 is fixedly installed on the upper end of the shaft rod 402, and a first bevel gear 407 is fixedly installed on the end of the shaft rod 402 extending into the bottom groove 406, and a movable groove 403 is provided on the outer side of the socket 3, and a screw rod 404 is rotatably connected to the inner side of the movable groove 403, and a second bevel gear 408 is fixedly installed on the end of the screw rod 404 extending into the bottom groove 406, and the first bevel gear 407 and the second bevel gear 408 are meshingly connected, and a reinforcing plate 405 is threadedly connected to the end of the screw rod 404 away from the second bevel gear 408, and one end of the reinforcing plate 405 is slidably connected to the inner side of the movable groove 403, and the end of the reinforcing plate 405 away from the movable groove 403 is clamped with the clamping groove 9, and the shaft rod 402 is close to the bottom groove 406. A limit gear 5 is fixedly installed on the outer wall of one end of the near operating head 401, and a limit mechanism 6 is fixedly installed on the upper end of the socket 3. The socket 3 is movably connected to the limit gear 5 through the limit mechanism 6. The operating head 401 is used to operate the shaft 402 to rotate on the socket 3, so that the first bevel gear 407 connected to the lower end of the shaft 402 engages with the second bevel gear 408, and the second bevel gear 408 drives multiple screws 404 to rotate synchronously in the movable groove 403. Due to the rotation of the screw 404, the reinforcing plate 405 connected to the outer thread slides out of the movable groove 403 and is stuck in the card slot 9 in the slot 8 to complete the installation. The structure first adopts an equi-angle hexagonal socket 3, so that the connection effect and force use have better stability and higher safety, and the socket 3 is not a hollow structure, so the load-bearing effect is better and it is not easy to be damaged;
[0021] The limiting mechanism 6 includes an installation box 601, which is fixedly installed on the upper end of the socket 3.

A spring 605 is sleeved on the outer side of the end of the pull rod 603 close to the moving plate 606. A clamping block 602 is fixedly connected to the side of the moving plate 606 away from the spring 605. The clamping end of the clamping block 602 movably penetrates the box wall of the installation box 601 and is plugged into the tooth groove on the outer side of the limiting gear 5. When the socket 3 and When the car top seat 7 is connected, it is necessary to pull the pull rod 603 through the pull plate 604 to make the shift plate 606 connected to the pull rod 603 slide, and the shift plate 606 compresses the spring 605. At the same time, the block 602 connected to the shift plate 606 is separated from the tooth groove of the limiting gear 5 on the outside of the shaft rod 402. When the fixing mechanism 4 connects the socket 3 and the car top seat 7, the pull plate 604 is released, so that the spring 605 resets and the shift plate 606 pushes the block 602 to be stuck in the gear groove of the limiting gear 5 on the outside of the shaft rod 402, thereby effectively avoiding the accidental loosening of the shaft rod 402, which indirectly causes the screw rod 404 to move, and affects the connection stability between the socket 3 and the car top seat 7.
[0022] refer to Figure 4 The outer side of one end of the reinforcing plate 405 is symmetrically fixedly connected to the limiting block 13, and one end of the reinforcing plate 405 is slidably connected to the inner side of the movable groove 403 through the limiting block 13.

The reinforcing plate 405 with the screw sleeve 14 is threadedly connected to the outer side of the screw 404, so that the reinforcing plate 405 can be easily adjusted and connected and fixed to the card slot 9.
[0023] refer to Figure 2 and Figure 5 and Figure 6The outer side of the installation box 601 is symmetrically fixedly connected with a fixing plate 11, and the inner side of the fixing plate 11 is provided with a fixing hole 12. The inner side of the installation box 601 is symmetrically provided with a slide groove 15, and the end of the moving plate 606 is slidably connected to the inner side of the slide groove 15. The upper end of the installation box 601 is rotatably connected with an L-shaped block 16, and the L-shaped block 16 and the pull plate 604 are movably connected. The fixing plate 11 with the fixing hole 12 is used to fix the installation box 601 through the fixing plate 11, and the slide groove 15 at the installation box 601 can facilitate the sliding of the moving plate 606, thereby ensuring the stability of the moving plate 606. During the operation of the operating head 401, after pulling a certain length through the pull plate 604, the L-shaped block 16 on the installation box 601 can be flipped 180 degrees, so that the L-shaped block 16 can limit the pull plate 604, so that the staff does not need to hold the pull plate 604 by hand during installation.
[0024] Principle and advantages of use: During use, first insert the socket 3 into the slot 8 at the upper end of the car top seat 7, then after pulling the pull plate 604 for a certain length, flip the L-shaped block 16 on the installation box 601 by 180 degrees, so that the L-shaped block 16 can limit the pull plate 604. When pulling the pull plate 604, the pull rod 603 connected to the pull plate 604 drives the moving plate 606 to slide, and the moving plate 606 compresses the spring 605. At the same time, the block 602 connected to the moving plate 606 is separated from the tooth groove of the limiting gear 5 on the outer side of the shaft rod 402. Then, the operating head 401 is used to operate the shaft rod 402 to rotate on the socket 3, so that the first bevel gear 407 connected to the lower end of the shaft rod 402 meshes with the second bevel gear 408, and the second bevel gear 408 drives multiple screw rods 404 to rotate synchronously in the active groove 403. Due to the rotation of the screw rod 404, the reinforcing plate 405 connected to the outer thread slides out of the active groove 403 and is stuck in the card slot 9 in the slot 8 to complete the installation.
[0025] After the installation is completed, pull the pull plate 604 and flip the L-shaped block 16 onto the installation box 601, then release the pull plate 604 to allow the spring 605 to reset and move the lower plate 606 to push the block 602 into the gear groove of the limiting gear 5 on the outside of the shaft 402, so as to limit the fixing mechanism 4 and ensure the safety of the elevator.
