Abstract
Description
Technical Field
[0001] This utility model belongs to the field of elevator technology, and specifically relates to a quick-installation plug-in elevator car. Background Technology
[0002] In traditional elevators, the connection between car walls must be performed entirely outside the car. Since the car walls are typically over 2 meters high, the connection points in the middle of the car walls are difficult for installers to reach from outside the car. Furthermore, the space between the car walls and the shaft walls is sometimes too narrow, making it impossible to perform the connection operation inside the shaft, significantly impacting installation efficiency. In some traditional car structures facing this situation, the connection between the car walls usually needs to be performed outside the shaft before the entire car is hoisted into the shaft and secured to the car floor. However, this method is still limited by space, resulting in significant operational difficulties, low efficiency, and certain safety risks.
[0003] This utility model adopts a plug-in quick-assembly structure, which allows installers to assemble the car walls and position the car walls and car bottom inside the car, solving the problems of traditional elevator cars requiring installers to assemble them outside the car (which is inefficient and unsafe) and the difficulty of assembly due to the limitation of shaft space. Summary of the Invention
[0004] To address the above shortcomings, the purpose of this utility model is to provide a quick-installation plug-in elevator car, which solves the problem that the structure of a transmission elevator car cannot meet the demand of the elevator installation market for significantly increased elevator installation efficiency.
[0005] The technical solution adopted by the utility model is: a quick-installation plug-in elevator car, which is mainly composed of a car top, a car bottom and a car wall. The key technical point is that the buckle provided on one side of the car wall and the slot provided on the adjacent side of the car wall are fastened together by mutual plugging.
[0006] Preferably, the buckle is divided by the outermost circular edge, and tapers in a conical shape to both sides to form two circular planes of different sizes, with a through hole in the middle of the two circular planes.
[0007] Preferably, the slot is L-shaped in general, including a wide slot for the buckle to pass laterally and a narrow slot for the buckle to slide in and lock into place at the base.
[0008] Priority is given to installing buckles on the first short bend surfaces on both sides of the rear middle car wall.
[0009] Preferredly, a slot is provided on the first short bend surface on one side of the rear car wall, and a buckle is provided on the outer side of the large flat surface of the other side of the car wall.
[0010] Preferredly, a slot is provided on the first short bend surface on one side of the side car wall and a buckle is provided on the first short bend surface on the other side.
[0011] Priority is given to the front car wall having a slot on the outer side of the large plane of the car wall.
[0012] Preferredly, a rectangular slot is provided at the lower end of each car wall, and a welding nut that mates with the rectangular slot is provided at the bottom of the car. The rectangular slot at the lower end of the car wall rests on the threaded rod of the flange bolt at the bottom of the car. A fixing clip is installed at the connection between the upper part of the car wall and the side flange of the car top.
[0013] Preferably, the clamping piece is R-shaped, with its lower part opening at a certain angle and having elastic clamping force.
[0014] The beneficial effects of this utility model are as follows: A quick-assembly plug-in elevator car, wherein a buckle on one side of the car wall and a slot on the adjacent side of the car wall are interlocked and locked together. This car allows installers to position the car walls and floor and assemble the car walls from inside the car. It solves the problems of traditional elevator cars requiring installers to assemble them outside the car (low efficiency and safety) and the difficulty of assembly due to space constraints in the shaft; it significantly shortens the car installation time, saving 50%-75% of the car assembly time compared to traditional elevator car assembly methods; and it reduces the number of installers required, as traditional elevator car assembly requires 2-3 people, while this invention only requires 1 person to complete the car assembly.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figures 1-10 The present invention will be further described in detail below with reference to specific embodiments.
[0028] The car of this utility model is composed of multiple components, including a rear middle car wall 1, a rear car wall 2, a side car wall 3, a front car wall 4, a car top 5, and a car bottom 6. The rear middle car wall 1, the rear car wall 2, the side car wall 3, and the front car wall 4 are respectively connected and locked to each other by a buckle 7 fixed on each other and a slot 9 provided on one side of the adjacent car wall through a sliding fit.
[0029] like Figure 3As shown: In this embodiment, clips 7 are installed on each car wall. These clips are made of nylon and taper in a conical shape towards both sides, with the outermost circular edge serving as the boundary. The two sides are circular planes of different sizes, one large and one small, with a through hole in the middle. The small plane corresponds to a hole on the car wall for installing the clip 7. The small plane of the clip 7 contacts the car wall panel, and its small hole is concentrically aligned with the mounting hole on the car wall. The large plane is used to fit against the pop rivet 8. The pop rivet 8 passes through the small hole, and the clip 7 is firmly pressed and fixed to the car wall panel through a riveting operation.
[0030] like Figure 4 As shown: A slot 9 is machined on the car wall. Its overall shape is L-shaped. As shown in the figure, there is a wide slot 92 for the buckle 7 to pass through laterally, and a narrow slot 91 for the buckle 7 to slide into and lock.
[0031] like Figure 5 The diagram illustrates the placement of various car wall clips 7 and slots 9. Clips 7 are provided on the first short bend surfaces on both sides of the rear middle car wall 1. Slots 9 are provided on the first short bend surface on one side of the rear car wall 2, and clips 7 are provided on the outer side of the large plane of the other side car wall. Slots 9 are provided on the first short bend surface on one side of the side car wall 3, and clips 7 are provided on the first short bend surface on the other side. Slots 9 are provided on the outer side of the large plane of the front car wall 4.
[0032] like Figure 2 As shown: The installation sequence of the car components in this embodiment is as follows: The car top 5 and car bottom 6 are pre-placed in the aisle with their upper and lower centers aligned. The car top 5 is pre-lifted and fixed to the upper beam (this is not specifically related to the content of this application, so the connection between the car top and the upper beam is not described). Then, the rear middle car wall 1 is installed first, followed by the rear car wall 2, side car wall 3, and front car wall 4 installed counterclockwise to the left. Then, starting from the rear middle car wall 1, the rear car wall 2, side car wall 3, and front car wall 4 are installed clockwise to the right.
[0033] like Figure 6 As shown: Several rectangular slots 10 are provided on the upper part of the car wall. The width of these slots can accommodate the screws of M6 flange bolts 12, and there is a certain margin in width. One side of the slots overlaps with the outer edge of the car wall, so that they are open on one side of the car wall.
[0034] like Figure 7 As shown: Welding nuts 11 are welded to the inner periphery of the car bottom 6. Flange bolts 12 are pre-installed on each welding nut 11 on the outer periphery. After being screwed in for a certain length of thread, a certain gap is left so that the rectangular slot 10 at the bottom of the car wall has enough insertion space.
[0035] like Figure 8As shown: A clamping piece 13 with elastic clamping force is used. Its overall shape is R-shaped. The lower part can open at a certain angle and generate a certain clamping force. During the installation of various car walls, after the rectangular slot 10 at the bottom of the car wall is aligned and positioned with the flange bolts 12 on the outer side of the car bottom 6, in order to prevent the car wall from tilting, this clamping piece 13 is used to temporarily clamp the upper car wall panel and the bent edge panel on the outer side of the car top 5. This can keep the car wall vertical and fixed, so that the installers do not need to support the previous car wall by hand when installing the car walls in sequence.
[0036] like Figure 9 The diagram illustrates the final position of the buckle 7 after assembly with the slot 9. At this point, the root of the rectangular slot 10 below the car wall is seated and in contact with the flange bolt 12, while the root of the buckle 7 has slid into the narrow opening of the slot 9. The width of the narrow opening and the part of the buckle 7 that is attached to the car wall panel are designed to achieve a certain clamping force so that the contact surfaces of the two car walls are tightly pressed together and the buckle 7 has no space to wobble in any horizontal direction within the narrow opening of the slot 9.
[0037] like Figure 10 The diagram illustrates the process of installing the car wall inside the car. Taking the installation of the side car wall 3, connected to the rear car wall 2, as an example, the rear middle car wall 1 and the rear car wall 2 are already in place. The installer holds the side car wall 3 inside the car, first extending its upper end out of the car and lifting it to a certain height. Simultaneously, the installer slowly rotates the side car wall 3 so that its upper end rests against the outer edge of the car roof 5 while its lower end moves outwards. During the rotation, the wide opening of the first upper slot 9 on the side car wall 3 is aligned with the first upper buckle 7 on the rear car wall 2 and passed over it. As the car wall rotates... Sequentially, the wide openings of the second to the bottom slots 9 are passed over the clips 7. The car wall is then pushed outwards to maintain a certain verticality, with its lower end slightly outside the car floor plane. A downward force is then applied to lower the car wall until the root of the rectangular slot 10 below it is in contact with the flange bolt 12, and simultaneously the root of the clip 7 has slid into the narrow opening of the slot 9. The installer then holds the clamping piece 13 from inside the car, extending it upwards from the top of the car, and clamps the clamping piece 13 onto both sides of the upper edge plate of the side car wall 3 being installed and the bent edge plate on the outer side of the car roof 5. The installation of the remaining car walls follows the same method.
[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
