Technical Field

[0001] This utility model relates to the field of elevator cars, and in particular to an auxiliary device for processing the bottom frame of an elevator car. Background Technology

[0002] An elevator is a permanent transportation device that serves several specific floors within a building. Its car moves along at least two rigid tracks perpendicular to the horizontal plane or at an angle of less than 15° to the vertical. With technological advancements, elevators have continuously evolved. Currently, elevators mainly consist of a traction system, a guiding system, a car, a door system, a weight balancing system, an electric drive system, an electrical control system, and a safety protection system. The car is the box-shaped space used by the elevator to carry and transport people and goods. The car generally consists of major components such as the car floor, car walls, car top, and car doors, and is the body component of the elevator used to transport passengers, goods, and other loads.

[0003] A search revealed Chinese Patent Publication No. CN202221838626.6, which discloses an elevator car welding frame, comprising a car panel fixing frame and a tilting motor. The car panel fixing frame has turntable bearings installed inside both sides, and mounting blocks are installed inside the turntable bearings. Electric push rods are installed inside the mounting blocks, and top plate suction cups are installed at the output ends of the electric push rods. A tilting motor is installed on the side of the mounting block away from the electric push rods. The inner surface of the car panel fixing frame has left and right adjustment grooves, and left and right adjustment sliders are installed inside the left and right adjustment grooves. This elevator car welding frame uses the electric push rods on both sides of the car panel fixing frame and the top plate suction cups to adsorb and fix the top and bottom plates of the elevator car, and also uses side plate suction cups and side plate support fixing plates to adsorb and fix the side plates of the elevator car, facilitating the welding of the side plates and the top and bottom plates of the elevator car, thus improving welding accuracy and efficiency.

[0034] The first fixing mechanism 5 is mounted on the support frame 4 and is used to limit the position of the car frame;

[0035] The first fixing mechanism 5 includes a first bidirectional lead screw 503, which is disposed inside the support frame 4. A first motor 502 is fixedly mounted on the surface of the support frame 4. The output shaft end of the first motor 502 is fixedly connected to the first bidirectional lead screw 503. A first slider 504 is symmetrically arranged in the first positioning groove 501. A first clamping plate 505 is fixedly connected to the top of the first slider 504. The first motor 502 drives the first bidirectional lead screw 503 to rotate. After the first bidirectional lead screw 503 rotates, it drives the first slider 504 and the first clamping plate 505 to slide. The car bottom frame is clamped by changing the spacing of the first clamping plate 505.

[0036] The second fixing mechanism 6 is installed on the first fixing mechanism 5 and is used to clamp the car frame.

[0037] The second fixing mechanism 6 includes a second bidirectional lead screw 603, which is disposed inside the first clamping plate 505. A second motor 602 is fixedly installed on one side of the first clamping plate 505. The output shaft end of the second motor 602 is fixedly connected to the second bidirectional lead screw 603. The second clamping plate 605 is symmetrically arranged in the second positioning groove 601. The second clamping plate 605 is fixedly connected to the second slider 604. The second motor 602 drives the second bidirectional lead screw 603 to rotate. After the second bidirectional lead screw 603 rotates, it drives the second slider 604 and the second clamping plate 605 to move closer to each other, thereby clamping the bottom frame again and preventing the bottom frame from shaking during the welding process.

[0038] Reference Figure 3A first positioning groove 501 is formed at the center of the top of the support frame 4, and a first bidirectional lead screw 503 is rotatably connected inside the first positioning groove 501. A first clamping plate 505 is slidably connected to the top of the support frame 4, and the first bidirectional lead screw 503 is threadedly connected to the first slider 504. A second positioning groove 601 is formed on one side of the first clamping plate 505, and the second bidirectional lead screw 603 is rotatably connected inside the second positioning groove 601. The second slider 604 is threadedly connected to the second bidirectional lead screw 603. Rubber anti-slip pads are provided on the surfaces of both the second clamping plate 605 and the first clamping plate 505. The rubber anti-slip pads on the surfaces of both the second clamping plate 605 and the first clamping plate 505 improve the fixing effect on the welding material of the bottom frame.

[0039] Reference Figure 1 The support frame 4 has a through groove 7 on its surface. The support frame 4 has a limiting mechanism 8 at its bottom. The through groove 7 allows the car bottom frame to be placed through the support frame 4. When clamping and welding the car bottom frame, the bottom of the car bottom frame can also be welded through the through groove 7.

After releasing the fixation, the support frame 4 can rotate along the fixed seat 3, facilitating the welding of the bottom frame.

[0041] Working principle: The bottom frame material to be welded is placed on the support frame 4. The first motor 502 is started according to the size. The first motor 502 drives the first bidirectional lead screw 503 to rotate. The rotation of the first bidirectional lead screw 503 drives the first slider 504 and the first clamping plate 505 to move closer together and clamp the material. The second motor 602 is started to drive the second bidirectional lead screw 603 to rotate. The rotation of the second bidirectional lead screw 603 drives the second slider 604 and the second clamping plate 605 to move closer together and clamp the remaining material, which facilitates the welding of the material. After welding the top, the bottom is welded through the through groove 7 for easy use.
