[0002] During the installation of chemical pipe gallery frames, quick auxiliary fixing is required. First, it improves installation efficiency. By using auxiliary fixing tools, workers can quickly position and secure the iron frame, thereby accelerating the construction progress. Second, auxiliary fixing can improve installation accuracy and ensure the stability and safety of the iron frame structure. During the installation process, auxiliary fixing tools can help workers precisely adjust the position and angle of the iron frame, avoiding installation errors caused by human factors. Finally, auxiliary fixing can also reduce the installation difficulty. Especially for large or complex iron frame structures, appropriate auxiliary fixing measures can make the installation process safer and more convenient.

[0003] However, currently, temporary support frames are mainly used to fix the iron frames, or fasteners such as bolts and nuts are used to quickly lock the position of the iron frames. However, these methods are still time-consuming and labor-intensive, and cannot flexibly and quickly fix the relative position of the pipe gallery structure. Therefore, a fast, simple, time-saving and labor-saving fixing device is urgently needed. Utility Model Content

[0033] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] Example 1

[0035] refer to Figures 1 to 5 , a quick fixing device for facilitating the construction of a pipe gallery frame, comprising:

[0036] guide frame;

[0037] The screw 5 is rotatably disposed in the guide frame, and the upper portion of the screw 5 has a first external thread, and the lower portion of the screw 5 has a second external thread;

[0038] The upper slider 4 is slidably disposed in the guide frame and is disposed on the upper section of the screw 5. The upper slider 4 is provided with a first internal thread that cooperates with the first external thread to drive the screw 5 to rotate;

[0039] The lower slider 3 is slidably disposed in the guide frame and is disposed at the lower section of the screw 5. The lower slider 3 is provided with a second internal thread that cooperates with the second external thread, and is used to drive the lower slider 3 to move up and down, fixing and loosening the pipe gallery frame;

[0040] The pitch of the first external thread is greater than the pitch of the second external thread, and the rotation direction is the same. The tangent value of the thread lead angle of the first external thread is much greater than the friction coefficient of the friction pair, which is used to realize the upper slider 4 driving the screw 5 to rotate. The tangent value of the thread lead angle of the second external thread is less than the friction coefficient of the friction pair, which is used to realize the self-locking of the lower slider 3.

[0041] The quick fixing device of the utility model mainly utilizes the difference in thread lead angles and can only control the up and down movement of the lower slider in one direction through the upper slider, so that the fixing device has a real-time self-locking function.

[0042] The tangent value of the thread lead angle of some parts of the utility model is much larger than the friction coefficient of the friction pair, and only a small force is needed to regulate the movement of the lower slider to achieve fixation, which is simple and flexible to use.

[0043] The fixing device of the utility model has the characteristics of compact and simple structure design and low production cost, and is maintenance-free and has low labor cost.

[0044] The utility model is a unique and innovative design, which is in a sense out of the traditional fixing device model. Compared with most existing fixing devices, it will have a wider application space.

[0045] In this embodiment, the guide frame includes:

[0046] Outer frame 1;

[0047] The fixing frame 2 is fixedly connected to the lower end of the outer frame 1 , and the upper end of the fixing frame 2 is provided with an opening communicating with the outer frame 1 .

[0048] In this embodiment, the outer frame 1 includes:

[0049] Two U-shaped support rods, the two U-shaped support rods are arranged opposite to each other, and the upper slider 4 and the lower slider 3 are both provided with a limiting portion that cooperates with the groove of the U-shaped support rod;

[0050] A first crossbeam, the first crossbeam is connected to the upper ends of the two U-shaped support rods, and the end of the first end of the screw rod 5 is rotatably connected to the first crossbeam;

[0051] The second cross beam is connected to the middle and lower ends of the two U-shaped support rods. The second end of the screw rod 5 passes through the second cross beam and extends to the lower side of the second cross beam. The upper part of the cross beam is the upper section of the screw rod 5, and the lower part of the second cross beam is the lower section of the screw rod 5.

[0052] In this embodiment, the screw rod 5 is connected to the first crossbeam and the second crossbeam via a first rotary bearing 6 and a second rotary bearing 7 respectively.

[0053] In this embodiment, both the first rotary bearing 6 and the second rotary bearing 7 are thrust bearings.

[0054] In this embodiment, the lower slider 3 is divided into an upper structure and a lower structure. The first internal thread is arranged on the upper structure. The lower structure passes through the opening at the lower end and extends into the fixed frame 2. A hook is provided at the lower end of the lower structure. The middle of the upper structure and the lower structure is a hollow structure, which is used to provide space for the up and down movement of the screw 5.

[0055] In this embodiment, the fixing frame 2 is a rectangular fixing frame, and the extending direction of the rectangular fixing frame is perpendicular to the outer frame 1 .

[0056] Example 2

[0057] This embodiment is the specific use steps of Example 1, and the steps are as follows:

[0058] (1) In the initial state, the upper slider and the lower slider are located at the upper part of the upper and lower sections of the screw rod 5 respectively, and the opening of the rectangular fixing frame 2 reaches the maximum. The pipe gallery frame to be fixed is placed in the rectangular fixing frame 2. Since the tangent value of the thread lead angle of the upper part is much larger than the friction coefficient of the friction pair, the upper slider 4 can be easily pushed downward by hand, thereby driving the screw rod 5 to rotate in the forward direction, and then pushing the lower slider 3 to gradually move downward, the rectangular fixing opening is reduced, and the pipe gallery frame is quickly and temporarily fixed in a very short time.

[0059] (2) Since the tangent value of the thread lead angle of the lower part is less than the friction coefficient of the friction pair, the lower slider 3 can only be moved by rotating the screw 5, and the lower slider 3 cannot push the screw 5 to rotate in turn, thus achieving self-locking of the lower slider 3. Therefore, the force exerted by the pipe gallery frame on the lower slider 3 will not cause the lower slider 3 to move upward, loosening the temporary fixation, and ensuring the rapid and safe advancement of the pipe gallery frame construction.

[0060] (3) When the quick fixing device needs to be quickly removed, the upper slider 4 can be easily pushed upward by hand, thereby driving the screw 5 to rotate in the opposite direction, and then pushing the lower slider 3 to gradually move upward. The rectangular fixing opening is opened, thereby separating from the pipe gallery frame, and the fixing device is removed in a very short time for the next use.

[0061] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to fall within the scope of protection of the present invention.
