[0002] In the manufacturing process of elevator cars, car assembly is a crucial step. Traditional elevator car assembly methods primarily rely on manual measurement and adjustment. Workers need to repeatedly measure the positional relationships between adjacent car modules using tools such as measuring tapes and levels, and then manually adjust them. This is not only cumbersome and time-consuming, but also makes it difficult to guarantee assembly accuracy, easily leading to problems such as uneven seams and poor structural stability. With the continuous development of modular production concepts, elevator cars are gradually adopting modular designs, dividing the car into multiple modules for production, and then assembling these modules into a complete car.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, this utility model provides a modular rapid splicing and positioning device for elevator cars, including multiple car modules 1. Each car module 1 is provided with a positioning component 2 and an adjustment component 3 at the splicing edge. Adjacent car modules 1 are initially positioned by the positioning component 2 and precisely adjusted by the adjustment component 3.

[0023] The positioning component 2 includes a positioning pin body 21 and a positioning hole 22. The positioning pin body 21 is set on the splicing edge of one of the car modules 1, and the positioning hole 22 is correspondingly opened on the splicing edge of the adjacent car module 1. The positioning pin body 21 and the positioning hole 22 are adapted to each other. When splicing the elevator car modules 1, the splicing edges of the two adjacent car modules 1 are first aligned so that the positioning pin body 21 on the splicing edge of one car module 1 is aligned with the positioning hole 22 on the splicing edge of the other car module 1. Then, the car module 1 is pushed so that the positioning pin body 21 is inserted into the positioning hole 22 to complete the initial positioning. This can quickly achieve the initial positioning between adjacent car modules 1, avoid large positional deviations during splicing, and improve splicing efficiency.

[0024] The adjustment component 3 includes an adjustment bolt 31 and a fixing nut 32. The fixing nut 32 is fixedly installed on the splicing edge of the car module 1. The adjustment bolt 31 is threadedly connected to the fixing nut 32. The end of the adjustment bolt 31 abuts against the splicing edge of the adjacent car module 1. After the adjacent car module 1 has completed its initial positioning, the adjustment bolt 31 is rotated to move within the fixing nut 32, thereby adjusting the distance between the adjacent car modules 1. In conjunction with the positioning pin body 21 of the elastic telescopic structure, the precise adjustment of the splicing position of the car module 1 is achieved, ensuring the splicing accuracy and the stability of the splicing of the adjacent car modules 1.

[0025] It should be noted that the end of the positioning pin body 21 is provided with a guide cone surface 211. The guide cone surface 211 can play a guiding role in the process of the positioning pin body 21 being inserted into the positioning hole 22, making it easier for the positioning pin body 21 to enter the positioning hole 22 more accurately and improving the efficiency of preliminary positioning.

[0026] like Figures 1 to 4 As shown, the positioning pin body 21 is an elastic telescopic structure, including a pin 212, a spring 213, and a limiting block 214. One end of the pin 212 is connected to the car module 1, and the other end of the pin 212 is a free end. The spring 213 is sleeved on the surface of the pin 212, and the limiting block 214 is fixed to one end of the pin 212. The splicing edge of the car module 1 is provided with a mounting hole 215 to accommodate the pin 212 and the spring 213. One end of the spring 213 is connected to the bottom of the mounting hole 215, and the other end is connected to the limiting block 214. The positioning pin body 21 passes through the mounting hole 215. The positioning pin body 21 with elastic telescopic structure can play a buffering role during the splicing process, avoiding rigid collision between the positioning pin body 21 and the positioning hole 22 and causing damage. At the same time, it can also compensate for positional errors during the splicing process to a certain extent and improve the reliability of positioning.

[0027] Multiple adjustment components 3 are evenly arranged on the splicing edge of each car module 1. The multiple adjustment components 3 are evenly distributed and can adjust the splicing position of the car module 1 from multiple positions, making the adjustment more flexible and precise, and ensuring the overall stability of the car module 1 after splicing.

[0028] Locking bolts 4 are screwed into threaded holes on the splicing edge of car module 1. Locking holes 5 are correspondingly provided on the splicing edge of adjacent car modules 1. Locking bolts 4 pass through the threaded holes and are threaded into the locking holes 5. After the precise adjustment of car modules 1 is completed, adjacent car modules 1 are firmly connected together by locking bolts 4 to prevent loosening during subsequent use and to ensure the structural stability and safety of the elevator car.

[0029] The locating pin body 21 is made of high-strength alloy material, and the inner wall of the locating hole 22 is provided with a wear-resistant coating. The high-strength alloy material can ensure that the locating pin body 21 has sufficient strength and rigidity and is not easily deformed or damaged. The wear-resistant coating on the inner wall of the locating hole 22 can improve its wear resistance and extend the service life of the locating component 2.

[0030] The locking bolt 4 is a high-strength bolt. High-strength bolts have high connection strength and reliability, which can ensure that the connection between adjacent car modules 1 is firm and reliable, and meet the usage requirements of elevator cars.

[0031] Working principle and process: When assembling elevator car modules 1, first align the splicing edges of two adjacent car modules 1, so that the positioning pin body 21 on the splicing edge of one car module 1 is aligned with the positioning hole 22 on the splicing edge of the other car module 1. Then, push the car module 1 so that the positioning pin body 21 is inserted into the positioning hole 22, completing the initial positioning. At this time, if there is a deviation in the splicing position of the two car modules 1, the adjusting bolt 31 in the adjusting assembly 3 is rotated. The adjusting bolt 31 rotates and moves within the fixing nut 32, and its end abuts against the splicing edge of the adjacent car module 1, pushing the car module 1 to adjust its position until the splicing position is accurate. Finally, the locking bolt 4 is passed through the threaded hole on the splicing edge of the car module 1 and screwed into the locking hole 5 on the splicing edge of the adjacent car module 1 to lock and fix the adjacent car module 1, thus completing the splicing process. This greatly shortens the positioning time and improves the splicing efficiency. The entire splicing and positioning process is simple to operate, requires no complicated professional skills, reduces the labor intensity of operators, and helps to improve production efficiency.
