Description

Technical Field

[0001] The present invention belongs to the field of steel strip production, and particularly relates to a measuring device for a steel strip assembly. Background Art

[0002] During the operation of the parent-child device, realizing the separation of multiple-stage parent-child devices involves a series of multi-body interference and unsteady complex aerodynamic systems. Due to the common and specific problems of inter-stage interference, factors such as the size of the sub-stage components, the aerodynamic structure shape, the attitude during separation, the initial separation conditions, the position of the component centroid, and the separation timing of each stage all play important roles in the entire separation process.

[0003] The length of the steel strip assembly is one of the important technical indicators of the three-stage separation scheme, which to a certain extent determines the success or failure of the second and third stages of the actuation system. In the second stage, the outer baffle leaves the parent device in a fixed state such as flat impact under the action of the actuation mechanism, and then is affected by the flow field in the interference area, generating complex aerodynamic forces, exposing the hoop assembly, the sub-device, and the interior of the parent device to the flow field; in the third stage, the scattering process is a key link in the actuation system of the parent-child device. The actuation of the hoop assembly is a prerequisite for the scattering process. The length of the hoop assembly determines its force-tightening state, ensuring the stable attitude of the sub-device; the length of the hoop assembly has an important impact on the attitude of the sub-device after being force-scattered. The sub-device is scattered and separated in a severe complex aerodynamic interference between the sub-device and the parent device, the fairing, and the baffle, which may even affect the separation and damage effect of the parent-child device.

[0004] The traditional method for measuring the steel strip is to use a steel ruler or a tape measure to flatten it. The steel straight ruler is laid flat on the measurement reference surface, the steel strip assembly is placed on the steel straight ruler, one end of the steel strip assembly is fixed, and the other end is aligned with the scale for reading. The positions of the two ends of the steel strip are swapped and read again, obtaining a set of data, and the average value is taken after repeating three times. The data at this time is determined as the actual length of the steel strip assembly. This operation requires at least 2 people to cooperate to complete, the process is cumbersome, the measurement data has a large error, and there is a safety hazard of breaking the steel strip assembly.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figure 1-2 shown in FIGS. 4 and 5, a device for measuring the length of a steel strip assembly includes a base 1. Two fixing blocks 12 are provided at one end of the base 1, and a measuring device is provided at the other end. The measuring device includes a measuring support 4 fixed on the base 1. The measuring support 4 is connected to a sleeve 3. A measuring rod 2 is slidably arranged in the sleeve 3. One end of the measuring rod 2 is connected to a measuring block 11. A scale is provided on the sleeve 3.

[0021] In this application: The angle steel at the bottom of the base 1 is placed on the on-site workbench. The fixing blocks 12 are installed on the base 1 through countersunk head screws. The measuring support 4 is fixed on the base 1 through bolts 5, flat washers 6 and fixing nuts 7. During assembly, the measuring rod 2 is inserted into the sleeve 3, and then they are put into the measuring support 4 together and fixedly connected through nuts. When in use, as Figure 3 shown in FIGS. 6 and 7, a groove is provided on the fixing block 12. One end of the steel strip 13 is placed and fixed in the groove. The other end of the steel strip is placed in the groove of the measuring block 11. The steel strip assembly is tightened and straightened by pulling the measuring rod 2, and the measured value is read by reading the dimension scale line on the sleeve 3.

[0022] In this application, there are two fixing blocks 12. Different fixing blocks are selected according to the length of the steel strip. As Figure 3 and Figure 4 shown in FIGS. 8 and 9, a support seat 8 is provided on the base 1. Since the steel strip is relatively long and heavy, the support seat 8 can be used to support the steel strip.

[0023] Preferably, the measuring block 11 is connected to a measuring head 10. The measuring head 10 is threadedly connected to the measuring rod 2. A limit nut 9 is also provided between the measuring rod 2 and the measuring head. In this application, the measuring block 11 is connected to the measuring head 10 through four countersunk head screws. For steel strips of different lengths, the extension length of the measuring head 10 is controlled by the limit nut 9.

[0024] This application is particularly applicable to the detection of steel strips with a relatively narrow width. The detection process is as follows:

[0025] 1. Place one end of the steel strip assembly to be detected on the groove of the fixing block 12, and select a long or short fixing block for fixing according to the length of the steel strip assembly.

[0026] 2. Fix the other end of the steel strip assembly in the groove of the measuring block 11, and adjust the measuring rod 2 slightly to make it fit in smoothly.

[0027] 3. Check whether the steel belt assembly is in the groove on the base 1 and whether there are any bends or bulges.

[0028] 4. Slowly pull the measuring rod 2 outwards and observe the horizontal state of the steel belt assembly. When it can no longer be stretched, read the value.

[0029] 5. Record the scale value on the upper end face of the sleeve 3 at this time, and this value is the length value of the product to be inspected.

[0030] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
