Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all the embodiments. Based on the embodiments in this utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of this utility model.

[0026] As recorded in the background art, the traditional connection method between the elevator car frame and the diagonal tie rod often adopts a complex assembly structure, involving the precise alignment and fastening of multiple components. When installing on site, this connection method requires experienced technicians to conduct long-term debugging and calibration to ensure the precise fit between components. However, the on-site installation environment is complex and changeable, which may affect the accuracy and reliability of the installation. In addition, the traditional connection method also has problems such as a long installation period, bringing certain challenges to the construction and operation of the elevator system.

[0027] To solve this technical problem, this utility model provides an elevator diagonal tie rod connecting shaft structure.

[0028] Specifically, please refer to Figures 1-3 , the elevator diagonal tie rod connecting shaft structure specifically includes:

[0029] Car channel steel 1, a connecting shaft assembly 2 is inserted through the car channel steel 1, a locking groove 205 is provided on the connecting shaft assembly 2, a first locking plate 5 is inserted into the inner wall of the locking groove 205, and the first locking plate 5 is connected to the car channel steel 1 to realize the locking of the connecting shaft assembly 2.

[0030] The elevator diagonal tie rod connecting shaft structure provided by the utility model. In this application, through the provided connecting shaft assembly 2, the connecting shaft assembly 2 only needs to pass through the car channel steel 1 and be locked by the first locking plate 5, and then the next installation step can be carried out. Almost no on-site calibration is required, which greatly reduces the on-site installation steps and calibration work, significantly improves the installation efficiency, effectively avoids installation errors caused by on-site condition limitations, improves the reliability of the connection. The shortening of the installation time and the reduction of the calibration work directly reduce the labor cost and material loss, which is beneficial to controlling the overall project cost.

[0031] In order to enable the personnel in the technical field to better understand the solution of the utility model, the technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings.

[0032] It should be noted that, without conflict, the embodiments in the utility model and the features and technical solutions in the embodiments can be combined with each other.

[0033] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0034] Embodiment 1, please refer to Figures 1-3 , an elevator diagonal tie rod connecting shaft structure, including a car channel steel 1, a connecting shaft assembly 2 is inserted and connected on the car channel steel 1. The connecting shaft assembly 2 is provided with a locking groove 205, the inner wall of the locking groove 205 is inserted with a first locking plate 5, and the first locking plate 5 is connected to the car channel steel 1 to realize the locking of the connecting shaft assembly 2. In this application, through the provided connecting shaft assembly 2, the connecting shaft assembly 2 only needs to pass through the car channel steel 1 and be locked by the first locking plate 5, and then the next installation step can be carried out. Almost no on-site calibration is required, which greatly reduces the on-site installation steps and calibration work, significantly improves the installation efficiency, effectively avoids installation errors caused by on-site condition limitations, improves the reliability of the connection. The shortening of the installation time and the reduction of the calibration work directly reduce the labor cost and material loss, which is beneficial to controlling the overall project cost. Since the first locking plate 5 is tightly connected to the car channel steel 1, a firm locking structure is formed, effectively resisting various vibrations and impact forces generated during the operation of the elevator, thereby avoiding situations such as loosening and displacement of the connecting shaft assembly 2, and ensuring the smooth and safe operation of the elevator.

[0035] The connecting shaft assembly 2 is made of high-quality metal materials, ensuring strength and load-bearing capacity, with strong reliability, durability, and suitability for the working conditions of freight elevators with different load capacities. Manufacturing the connecting shaft assembly 2 with high-quality metal materials can adapt to the working conditions of various freight elevators with different load capacities, greatly expanding the application scope and usage scenarios of the product. High-quality metal materials have excellent strength and load-bearing capacity, capable of withstanding the huge pressure and impact generated during the operation of high-load freight elevators, ensuring that the connecting shaft assembly 2 will not deform or be damaged during long-term use, thus extending the service life of the elevator and reducing maintenance and replacement costs. At the same time, its strong reliability and durability provide a solid guarantee for the safe and stable operation of the elevator, allowing users to use it with confidence.

[0036] Furthermore, as Figure 2 shown, the connecting shaft assembly 2 includes a first connecting shaft 201, and the outer surface of the first connecting shaft 201 is inserted and connected with the car channel steel 1; only by adjusting the length of the first connecting shaft 201 can the requirements of car frames with different widths be met, with strong flexibility. This design significantly enhances the flexibility and adaptability of the product, effectively reducing production costs and improving production efficiency.

[0037] Furthermore, as Figure 1 and Figure 3 shown, a locking groove 205 is opened on the first connecting shaft 201, and the first locking plate 5 is bolted to the car channel steel 1. The insertion of the first locking plate 5 into the locking groove 205 can limit the horizontal movement and rotation of the first connecting shaft 201, improving the stability of the connecting shaft assembly 2 during use. This structural design effectively restricts the horizontal movement and rotation of the first connecting shaft 201, greatly enhancing the stability and reliability of the connecting shaft assembly 2 during use. During the operation of the elevator, due to the action of vibration and inertial forces, the connecting shaft assembly 2 is prone to horizontal movement and rotation. If not effectively restricted, it will affect the running smoothness and safety of the entire elevator system. Through the tight insertion of the first locking plate 5 into the locking groove 205, the first connecting shaft 201 can be firmly locked, enabling it to maintain a stable position and state under various working conditions, thus ensuring the smooth, safe, and reliable operation of the elevator, extending the service life of the elevator, and reducing maintenance costs.

[0038] Furthermore, as Figure 1 and Figure 3As shown in the figure, at both ends of the first connecting shaft 201, there are fixedly connected second connecting shafts 202. A upper inclined pull rod 3 is sleeved on the outer surface of one of the second connecting shafts 202, and a lower inclined pull rod 7 is sleeved on the outer surface of the other second connecting shaft 202. The diameter of the second connecting shaft 202 is smaller than that of the first connecting shaft 201. This structural layout not only optimizes the overall structure, improves the rationality and efficiency of connection, but also realizes the rational utilization of materials and reduces the overall weight of the structure. The design of connecting shafts with different diameters fully considers the force characteristics and functional requirements of different components during connection. The first connecting shaft 201 bears the main load-bearing and connecting functions and requires a larger diameter to ensure strength; while the second connecting shaft 202 is mainly used for sleeving with the inclined pull rods. A smaller diameter can not only meet the connection requirements, but also save materials and reduce weight. This design realizes the optimal allocation of materials and the lightweight of the structure on the premise of ensuring the structural strength and stability, reduces the production cost, and improves the energy efficiency of elevator operation;

[0039] The upper inclined pull rod 3 and the lower inclined pull rod 7 are used to connect multiple carriages of the freight elevator, the carriage and the car bottom, which play an important role in the overall strength of the carriage. The hoistway size of large-load freight elevators is usually relatively large, which will result in a large distance between the elevator car guide rails and the hoistway wall. It is necessary to additionally increase diagonal braces in the guide rail brackets to ensure that the guide rail brackets have sufficient strength support for the elevator car guide rails, which will increase the cost of the elevator;

[0040] To reduce the use of diagonal braces in the guide rail brackets, by increasing the outer width of the carriage, the distance between the guide rails and the wall is reduced. At this time, in order to enable the inclined pull rods to still play a strengthening role in the carriage, this connecting shaft can meet different widening requirements of the carriage. Through a connecting shaft assembly 2 passing through the carriage channel steel 1, the lower inclined pull rod 7 and the upper inclined pull rod 3 are connected. In the case of different outer widths of the carriage, only by using the connecting shaft assembly 2 with the first connecting shaft 201 of the corresponding length can the strengthening effect of the upper inclined pull rod 3 between the carriages, between the carriage and the car bottom be ensured.

[0041] In Embodiment 2, the elevator inclined pull rod connecting shaft structure provided in Embodiment 1 is further optimized. Specifically, limit members are provided at the ends of the two second connecting shafts 202 that are away from each other. The limit members are used for limiting the upper inclined pull rod 3 and the lower inclined pull rod 7 to prevent the upper inclined pull rod 3 and the lower inclined pull rod 7 from separating from the second connecting shaft 202. During the frequent start-stop and operation of the elevator, various dynamic loads and impacts will be generated. Without reliable limiting measures, the inclined pull rods may displace or even fall off, thus seriously affecting the operation safety of the elevator. By setting the limit members, it can be ensured that the inclined pull rods always remain in the correct position and are tightly connected to the second connecting shaft 202, providing a strong guarantee for the stable operation of the elevator, reducing the possibility of accidents, and improving the reliability and safety of the elevator.

[0042] Furthermore, as shown in Figure 1 and Figure 3 , the limiting member includes two fastening nuts 203, and the two fastening nuts 203 are respectively threadedly connected to the outer surfaces of the two second connecting shafts 202. The upper inclined tie rod 3 and the lower inclined tie rod 7 can be limited by the fastening nuts 203. Nuts are common and easily obtainable standard parts with low cost. They can be firmly fixed to the second connecting shaft 202 through threaded connection. During the installation process, the upper inclined tie rod 3 and the lower inclined tie rod 7 can be limited simply by rotating the nuts, and the operation is convenient and fast.

[0043] Furthermore, as shown in Figure 1 and Figure 3 , nut gaskets 204 are sleeved on the outer surfaces of the two second connecting shafts 202, and the two nut gaskets 204 are both located on the side where the two fastening nuts 203 are close to each other. The setting of the nut gaskets 204 significantly enhances the stability of the connection between the fastening nuts 203 and the second connecting shafts 202, effectively reducing the possibility of loosening. During the operation of the elevator, due to the action of vibration and dynamic loads, the fastening nuts 203 are prone to loosening, thus affecting the limiting effect. The nut gaskets 204 can increase the contact area and disperse the pressure.

[0044] Embodiment 3 further optimizes the elevator inclined tie rod connecting shaft structure provided in Embodiment 1 or 2. Specifically, as shown in Figure 1 and Figure 3 , a support plate 4 is provided on one side of the car channel steel 1 close to the lower inclined tie rod 7. Slots 401 are opened on both sides of the support plate 4, and the inner walls of the slots 401 are inserted into the car channel steel 1. The setting of the support plate 4 can cooperate with the car channel steel 1 to improve the support for the first connecting shaft 201, so that the first connecting shaft 201 is supported by the cooperation of the car channel steel 1 and the support plate 4, significantly improving the support effect on the first connecting shaft 201 and greatly enhancing the stability and reliability of the structure. During the operation of the elevator, the first connecting shaft 201 bears forces and loads from all directions. If only supported by the car channel steel 1, it may cause excessive single-point stress, easily leading to deformation and fatigue damage. The additional support plate 4 and the car channel steel 1 form a double-support structure, which can more evenly distribute the load, reduce the pressure at a single point, effectively reduce the risk of deformation and damage. This double-support structure can also improve the vibration resistance of the entire system, keep the first connecting shaft 201 stable in a complex operating environment, extend the service life of the connecting shaft, and ensure the safe operation of the elevator.

[0045] Furthermore, a groove is formed on the car channel steel 1, and the support plate 4 is inserted into the inner wall of the groove. The groove and the card slot 401 are arranged such that the support plate 4 and the car channel steel 1 can be engaged and limited with each other. The design of the groove and the card slot 401 ensures the precise installation and stable connection between the support plate 4 and the car channel steel 1, effectively preventing the support plate 4 from shifting or loosening during use. This mutually engaged limiting structure can withstand large shear forces and tensile forces. When the elevator is running, even under strong vibrations and impacts, it can ensure that the support plate 4 is always tightly combined with the car channel steel 1, without misalignment or detachment, thereby providing continuous and stable support for the first connecting shaft 201, improving the reliability and safety of the entire structure, and reducing the failures and maintenance costs caused by component loosening.

[0046] Furthermore, as Figure 1 and Figure 2 shown, the number of locking grooves 205 is two. One of the locking grooves 205 is inserted with the first locking plate 5, and the inner wall of the other locking groove 205 is inserted with the second locking plate 6. The second locking plate 6 is installed on the support plate 4 through bolts. By providing two locking grooves 205 and respectively cooperating with the first locking plate 5 and the second locking plate 6, the first connecting shaft 201 can be locked from two different positions, dispersing the stress at the locking points and improving the reliability of locking. Even in extreme cases, if one locking point fails, the other locking point can still play a certain limiting role, thereby greatly reducing the safety risk and ensuring the smooth operation of the elevator and the safety of passengers' lives.
