Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of equipment manufacturing, in particular to a container lock assembling method and device. BACKGROUND

[0002] In the field of railway freight transportation, the accurate installation of container locks and their seats is the cornerstone of transportation safety. However, the current assembly process in this industry is still relatively traditional and extensive. For example, in the key process of seat assembly, the common method is to "mark a rough position by an operator, and then repeatedly measure to determine the relative position of the 8 seats" using a tape measure.

[0003] This traditional method highly depends on the operator's personal experience and feeling, introducing a lot of operational uncertainty from the marking reference to the measurement reading, which leads to poor assembly quality stability and consistency. Moreover, the process of "repeated measurement" is extremely time-consuming, making seat assembly a significant bottleneck in the entire assembly process and severely restricting operational efficiency. More worrying is that the operator must repeatedly walk and bend over the truck chassis to measure, which not only requires a lot of labor but also poses a high risk of falling from a great height.

[0004] The cumulative dimensional error introduced by the operator during the operation directly leads to poor relative position accuracy of the seats, which poses a significant safety risk for subsequent container locking. When the train is subjected to long-term vibration and impact, positioning deviations may result in poor locking or locking of the container, which can easily cause major traffic accidents such as container displacement or even falling off, and the locking of the container when it is lifted out, causing the vehicle to be lifted out and derailed. At the same time, the low operational efficiency also reduces the overall efficiency of truck assembly and maintenance. To compensate for the lack of operational reliability, repeated verification measures are needed, further increasing labor and time costs. This makes the traditional seat assembly method difficult to meet the current demand for high-quality and efficient railway freight equipment.

[0005] Therefore, there is an urgent need for an automated assembly method that can improve installation efficiency and has high reliability. SUMMARY

[0006] The present application aims to provide a container lock assembly method and device to solve the problem of low efficiency and poor reliability of existing railway freight container lock assembly.

[0007] In order to achieve the above object, the application adopts the following technical scheme: a container lock assembling device for assembling container locks of railway freight cars, comprising a fixed frame installed on the ground, the fixed frame comprising side beams arranged on both sides, end beams arranged at both ends, and a sleeper beam arranged between the two side beams; an end beam positioning pile is arranged on the outer side of the first end beam, and an end beam jacking cylinder is arranged on the outer side of the second end beam; an end lock assembling mechanism is arranged above each of the two end beams; a side beam jacking cylinder is arranged on one side of the sleeper beam, and a side beam positioning pile is arranged on the other side of the sleeper beam; a middle lock assembling mechanism is arranged in the middle of the side beam; and a vehicle body supporting device is arranged on the fixed frame.

[0008] Meanwhile, the application also provides a container lock assembling method applied to the above container lock assembling device, comprising the following steps: S1, installing the fixed frame at a specified position on the ground; hoisting the vehicle to a corresponding position above the fixed frame and slowly placing it on the vehicle body supporting device; S2, adjusting the positions of the first and second limiting plates according to the determined positioning reference; S3, placing 8 groups of locks at specified positions of the end beams and side beams of the fixed frame, and adjusting the lock core positions through the limiting plates to make the positioning points of each group of locks meet the positioning requirements; S4, after fixing the locks adjusted to the positions, withdrawing the limiting plates to complete the container lock assembling.

[0009] The principle and advantages of the application are as follows: The application determines the installation positions of the lock positions as a whole by designing the fixed frame, and no longer needs to determine the positions individually by marking. Meanwhile, the application converts the positioning reference by combining the fixed frame to realize the accurate assembling of the container locks. The vertical positioning reference is set according to the side beams, the horizontal positioning reference is determined according to the side beams and the sleeper beam, and the longitudinal positioning reference is determined according to the end beams, thereby ensuring the stability and effectiveness of the reference and improving the repeatability and standardization of the fixed frame. Meanwhile, the application adopts the rotating and cylinder lifting mode to complete the rapid positioning of the end and middle locks by the synergistic effect of the side beam jacking cylinder, the end beam jacking cylinder and the positioning pile. Through process test verification, the middle lock assembling process is enlarged by 2mm in the width direction of the vehicle body, the end lock is unchanged, the length direction is enlarged by 5mm and 10mm, (considering the welding shrinkage deformation, the size is increased relative to the original nominal size, such as 2259 is enlarged to 2261, 5853 is enlarged to 5858, and 11985 is enlarged to 11995 for assembling) to ensure that the size after assembling and welding meets the drawing requirements.

[0010] Through the explicit three-dimensional positioning reference, quick positioning installation is realized, wrong installation is avoided, error is reduced, and positioning accuracy is improved. Meanwhile, the structural design of the scheme is simple and stable, the manufacturing cost is low, the personnel operation difficulty is reduced by relying on the mechanical device assisted positioning, the operation is more simple and convenient, and the automation degree is improved. After appropriate adjustment, the device can adapt to the assembly of container locks of various types of flat cars, improve the overall adaptability, thereby reduce the assembly time and cost, improve the assembly reliability, and ensure the safe and stable operation of the car.

[0014] Scheme one Provided is a container lock assembly device for railway freight container lock assembly, as shown in the accompanying Figure 1 The fixed frame 1 is installed on the ground. In this embodiment, the overall cross section of the fixed frame 1 is rectangular, and the overall longitudinal section is trapezoidal, as shown in the accompanying Figure 2 The fixed frame 1 includes side beams 2 on both sides, with a length of 12486±10mm, end beams 3 at both ends, with a longitudinal length of 2500mm, and pillow beams 4 between the two side beams 2, with a longitudinal length consistent with that of the end beams 3 and a transverse width greater than that of the end beams 3. The pillow beams 4 are located between the two end beams 3 and are arranged side by side with the end beams 3.

[0015] An end beam positioning pile 5 is installed on the outside of the first end beam to fix the position of the end beam 3. An end beam jacking cylinder 6 is installed on the outside of the second end beam to control the positioning of the whole vehicle.

[0016] An end lock assembly mechanism 7 is installed above each of the two end beams. In this embodiment, the end lock assembly mechanism 7 includes four groups, each installed at a corner of the end beam 3. As shown in the accompanying Figure 3 and the accompanying Figure 4 Each group of end lock assembly mechanisms 7 includes a positioning seat mechanism 22 installed on the ground and a first limiting plate 8 used to define the end lock. The first limiting plate 8 is installed on the rotating shaft of the positioning seat mechanism 22 and is rotated by the positioning seat mechanism 22. As shown in the accompanying Figure 5 The lower part of the first limiting plate 8 is a first main plate 9 in overall square structure, which is installed on the rotating shaft of the positioning seat mechanism 22. A clamping groove 10 is provided on one side of the upper part of the first limiting plate 8, which is located above the first main plate 9 and has an opening facing outward. The other side is wedge-shaped, forming a U-shaped groove. During installation, the top of the end lock 11 can be located in the clamping groove 10, and the installation position is determined according to the positioning point 12 of the end lock 11.

[0017] As shown in the accompanying Figure 1 A side beam jacking cylinder 13 is installed on one side of each of the two pillow beams 4 to control the positioning of the vehicle. A side beam positioning pile 14 is installed on the other side of each of the two pillow beams 4 to fix the vehicle.

[0018] A middle lock assembly mechanism 15 is provided in the middle of the side beam 2. The middle lock assembly mechanism 15 includes two groups, each installed at the middle position of the two side beams 2. As shown in the accompanying Figure 6As shown, each set of central lock assembly mechanisms 15 also includes a positioning seat mechanism 22 and a second limiting plate 17 for defining the two central locks 16, which are arranged side by side. In this embodiment, as shown in the attached... Figure 7 As shown, the second limiting plate 17 includes a second main plate 18 with an overall trapezoidal structure, through which the second limiting plate 17 is mounted on the rotating shaft of the positioning seat mechanism 22. A first corresponding groove 19 for locking the first central lock and a second corresponding groove 20 for locking the second central lock are integrally formed on the upper part of the second main plate 18.

[0019] The first corresponding groove 19 and the second corresponding groove 20 form two branches on the upper part of the second main board 18. The opening of the first corresponding groove 19 faces the upper left, forming an L-shaped structure, which is used to limit the installation position of the first central lock. The opening of the second corresponding groove 20 faces the upper center, forming a G-shaped structure, which is used to limit the installation position of the second central lock.

[0020] In this embodiment, a vehicle body support device 21 is also provided on the fixing frame 1 to fix the vehicle position. The vehicle body support device 21 and the positioning seat mechanism 22 adopt an integral frame structure, which can be easily replaced with different support and positioning positions according to different vehicle models.

[0021] As attached Figure 1 As shown, the distances between adjacent end lock assembly mechanisms are 2256-2259 mm and 11985±6 mm, respectively; that is, the longitudinal distance between adjacent end lock assembly mechanisms is 2256-2259 mm, and the lateral distance is 11985±6 mm. The distance between end lock assembly mechanism 7 and adjacent middle lock assembly mechanism 15 is 5853±6 mm. End lock assembly mechanism 7 and middle lock assembly mechanism 15 located on the same side are located on the same lateral positioning reference; all assembly mechanisms are located on the same vertical positioning reference; and the assembly mechanisms arranged opposite each other are located on the same longitudinal positioning reference.

[0022] In this embodiment, as shown in Figure 8 (1), the transverse positioning reference is the transverse plane determined by the L-shaped outer plane formed by the side beam 2 and the pillow beam 4; the longitudinal positioning reference is the outer plane of the web of the end beam 3, along the direction of the middle beam; as shown in Figure 8 (2), the vertical positioning reference is the vertical plane perpendicular to the horizontal plane determined by the upper surface of the side beam 2, thereby simplifying the positioning process, ensuring the accuracy and stability of the positioning, and allowing for repeated operation.

[0023] Option 2 A container lock assembly method is provided, applied to the aforementioned container lock assembly device, as shown in the attached figure. Figure 9 As shown, it includes the following steps: S1, install the fixing frame 1 at a designated position on the ground; lift the vehicle to the corresponding position above the fixing frame and slowly place it on the vehicle body support device 21.

[0024] S2, adjust the positions of the first limiting plate 8 and the second limiting plate 17 according to the determined positioning reference and positioning pile.

[0025] S3, place the 8 groups of locks at designated positions of the end beam 3 and the side beam 2 of the fixing frame 1, and adjust the positions of the lock cores through the limiting plates, so that the positioning points 12 of each group of locks meet the positioning requirements.

[0026] In this embodiment, 4 groups of end locks 11 are placed at the four corners of the end beam 3, and 2 groups of middle locks 16 are placed at the middle positions of the side beam 2 at the same time. Figure 4 and Figure 6 As shown in the drawings, the positions of the end locks 11 and the middle locks 16 are adjusted respectively, so that the positioning points 12 of each group of locks are placed at the positions of the comparison points of the limiting plates, thereby ensuring that the locks are installed in place.

[0027] S4, after the locks are fixed after being adjusted to the positions, the limiting plates are withdrawn to complete the assembly of the container locks.

[0028] In this embodiment, after all the locks are adjusted to the positions, the locks are sequentially welded and fixed by welding, and then the limiting plates are withdrawn. The limiting plates are raised by the positioning seat mechanism 22 of the end lock assembly mechanism and the middle lock assembly mechanism until the locks are completely withdrawn from the clamping grooves of the limiting plates, and then the main plate of the limiting plate is controlled to rotate 90 degrees in the opposite direction of the slot of the limiting plate, thereby completing the assembly of the container locks.

[0029] In this embodiment, after the vehicle body is placed in the position, the horizontal and vertical jacking of the air cylinder is used to save time and effort. The positioning base point set at the reference beam (pillow beam) of the vehicle body also has the function of fine adjustment and compensation of the size of the screw rod. The consistency of the relative position of the lock seat relative to the vehicle body during lock seat assembly is ensured. In addition, the end lock assembly mechanism and the middle lock assembly mechanism have the functions of one-key lifting and overturning, and the lock seat positioning plate has the functions of profile positioning and foolproof device to avoid lock seat installation in reverse and misinstallation, thereby eliminating the frequent situation of lock seat installation in reverse. After the positioning mechanism is controlled to the position by air control, several groups of lock seats are placed close to the profile positioning plate to complete the lock seat assembly. The relative size of the 8 groups of lock seats is fixed through the fixed clamping tool, thereby ensuring 100% container drop and greatly improving the efficiency.

[0030] Through the process test of the embodiment, a large number of trial production data show that the size consistency of the tool assembly is excellent, and the size of the lock seat is completely qualified. The applicability of the tool is verified. In subsequent production, the detection cycle of the tool position is set, and whether the relative size of the tool is changed by external force or unknown factors is checked according to the production frequency. At the same time, the first and last pieces are checked in each shift production, so as to ensure the stable quality of the assembly size. In the width direction of the vehicle body, the middle lock assembly process is enlarged by 2mm, and the end lock is unchanged; in the length direction of the vehicle body, it is enlarged by 5 and 10mm, so as to ensure that the final assembly and welding size meets the requirements.

[0031] In the embodiment, aiming at the problems in the assembly of the traditional railway freight car container lock, such as lack of unified reference, relying only on the distance control of adjacent locks to cause installation error accumulation, and then causing safety accidents such as lock falling after long time running, and low efficiency caused by repeated verification. The scheme realizes technical breakthrough through innovative positioning reference design and mechanical auxiliary positioning mechanism, realizes the rapid positioning of the end and middle locks by combining rotation and cylinder lifting through the cooperative action of the side beam jacking cylinder, the end beam jacking cylinder and the positioning pile.

[0032] The scheme effectively solves the core contradiction of "no reference relying on personnel verification" in the traditional assembly through the clear three-dimensional positioning reference and mechanical auxiliary structure. On the one hand, the standardized reference design avoids the accumulation of installation errors, significantly improves the positioning accuracy, and fundamentally eliminates the risk of falling caused by improper installation; on the other hand, the rotary and lifting type mechanical positioning replaces the pure personnel operation, cooperates with the reference conversion mechanism to realize rapid clamping, greatly reduces the time cost of repeated verification, and significantly improves the assembly efficiency. Compared with the traditional assembly method, the scheme not only has a simpler operation process, but also ensures the consistency and stability of batch assembly through the stable support of the positioning pile and the cylinder, and has lower manufacturing cost. After appropriate adjustment, it can also adapt to the assembly of container locks of various types of flat cars, and has the comprehensive technical advantages of "accurate positioning, efficient assembly, safe and reliable, and cost optimization".

[0033] The above is only an embodiment of the present application, and the specific technical solutions and / or common knowledge of the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the technical solutions of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, which will not affect the effect and practicality of the patent. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
