Description

Technical Field

[0001] This utility model belongs to the technical field of side support legs for self-loading and unloading emergency generators, specifically relating to an electric push rod telescopic support leg structure for self-loading and unloading emergency generators. Background Technology

[0002] Self-loading emergency generators play a crucial role in numerous scenarios such as emergency rescue, field operations, and temporary power supply. They can quickly and conveniently provide power support for various equipment and meet the power needs in emergency situations. To ensure that self-loading emergency generators can operate stably under different terrain conditions, four electric push rod telescopic outriggers are usually installed on both sides. The height and angle of the telescopic outriggers can be adjusted by electric push rods to keep the generator in a horizontal and stable state, thereby ensuring the normal operation of the generator and the safe operation of the electrical equipment. When not in use or when the generator is moved, the four electric push rod telescopic outriggers can be rotated to a horizontal state and folded to the side of the generator to reduce the overall space occupied and improve portability.

[0003] Currently, existing self-loading and unloading emergency generator electric push rod telescopic outrigger structures generally use bolt locking to fix the electric push rod when rotating it to a vertical (working) or horizontal (retracted) state. Using bolts for locking requires tools, and operators need to spend time finding suitable tools and manually tightening or loosening the bolts. The whole process is cumbersome, resulting in slow switching of the electric push rod's state and reducing the overall deployment efficiency of the electric push rod telescopic outrigger structure. Especially in emergency situations, where every second is crucial, this inefficient operation method may delay the generator's deployment time and affect the timely implementation of emergency rescue and other work. Therefore, this utility model proposes a self-loading and unloading emergency generator electric push rod telescopic outrigger structure. Utility Model Content

[0024] 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.

[0025] Example

[0026] Please see Figures 1 to 6 This embodiment of the present invention provides the following technical solution: a telescopic outrigger structure for an electric push rod of a self-loading and unloading emergency generator, comprising four outrigger assemblies 1 located at the four corners of the self-loading and unloading emergency generator 2. Each outrigger assembly 1 includes a rotating fixed base 11 fixed to the side of the self-loading and unloading emergency generator 2, a transverse support column 12 rotatably mounted on the rotating fixed base 11, an electric push rod 13 rotatably mounted at the front end of the transverse support column 12, and a bottom support leg 14 mounted on the free end of the electric push rod 13. In actual application, the electric push rod 13 is rotated to a vertical working state, and the operation of the electric push rod 13 causes the bottom support plate at the bottom end of the bottom support leg 14 to press firmly against the ground, thus effectively supporting the self-loading and unloading emergency generator 2. When not in use, the electric push rod 13... 3. The operation causes the bottom support leg 14 to retract, and then the electric push rod 13 is directly rotated until the top of the transverse support column 12 is in a horizontal state. Then the transverse support column 12 is rotated to the side of the self-loading and unloading emergency generator 2, so that the entire support leg assembly 1 can be retracted to the side of the self-loading and unloading emergency generator 2, which facilitates the transfer of the self-loading and unloading emergency generator 2. The front end of the transverse support column 12 has two seat plates 15 symmetrically welded and fixed to the front and rear of the electric push rod 13. The top outer side of the two seat plates 15 is fixed with a rotating base plate 151 by bolts. A rotating shaft 152 is installed between the two rotating base plates 151. The electric push rod 13 is rotatably connected to the rotating base plate 151 through the rotating shaft 152, so that the electric push rod 13 can rotate smoothly at the front end of the transverse support column 12.

[0027] Also includes

[0028] The upper U-shaped seat 121 is welded and fixed to the top surface of the transverse support column 12, the upper limit seat 131 is welded and fixed to the top side of the electric push rod 13 and corresponds to the upper U-shaped seat 121, the lower U-shaped seat 122 is welded and fixed to the bottom surface of the transverse support column 12, and the lower limit seat 132 is welded and fixed to the bottom side of the electric push rod 13 and corresponds to the lower U-shaped seat 122. When the electric push rod 13 rotates to the vertical working state, the lower limit seat 132 will be screwed into the lower U-shaped seat 122. When the electric push rod 13 rotates to the top of the transverse support column 12 and is in a horizontal state, the upper limit seat 131 will be screwed into the inner side of the upper U-shaped seat 121.

[0029] The cylindrical pin 16 is provided. The surfaces of the upper U-shaped seat 121 and the lower U-shaped seat 122 are both provided with circular insertion holes 123 for the cylindrical pin 16 to pass through. The surfaces of the upper limit seat 131 and the lower limit seat 132 are both provided with central holes for the cylindrical pin 16 to pass through. The cylindrical pin 16 passes through the lower limit seat 132 and the lower U-shaped seat 122, so as to realize the insertion between the lower limit seat 132 and the lower U-shaped seat 122, which can stably limit the electric push rod 13 in the vertical working state.

[0030] The push-type quick-stop structure 17 is provided on the lower limit seat 132 and the upper limit seat 131 to quickly stop the cylindrical pin 16 after it has passed through, thereby improving the convenience of stopping and making it easier to quickly release the stop and realize the rotation operation of the electric push rod 13.

[0031] In this embodiment, preferably, the press-type quick-release structure 17 includes a cylindrical pressing groove 171 formed on the side of the lower limit seat 132 and the upper limit seat 131, a circular pressing block 173 movably installed in the cylindrical pressing groove 171, and a pressing rod 174 welded and fixed to the top surface of the circular pressing block 173. The top end of the pressing rod 174 extends to the outside of the lower limit seat 132 or the upper limit seat 131 and is fixed with a movable plate 175. A limit block 176 is welded and fixed to the inner side of the front end of the movable plate 175. A limit block 176 is formed at the center of the cylindrical pin 16 and is connected to the limit block 176. The end of the limiting block 176 extends into the annular groove 161 corresponding to the 6, allowing for quick and stable positioning of the cylindrical pin 16. A spring 172 is fitted onto the bottom surface of the pressing rod 174 relative to the inner side of the cylindrical pressing groove 171, and the spring 172 is positioned at the top of the circular pressing block 173. Under the pressure of the spring 172, the movable plate 175 can stably adhere to the surface of the upper limit seat 131 or the lower limit seat 132 during daily use, and the end of the limiting block 176 is stably engaged within the annular groove 161. To ensure the stability of the cylindrical pin 16, if the limitation on the electric push rod 13 needs to be quickly released, simply press the circular pressing block 173, compressing the spring 172 and causing the pressing rod 174 to move along with the movable plate 175, causing the end of the limiting block 176 to move out of the annular groove 161. At this point, the cylindrical pin 16 can be directly pulled out. Without the cylindrical pin 16, the limitation on the electric push rod 13 can be quickly released. Then, the electric push rod 13 is rotated up until the top of the horizontal support column 12 is in a horizontal state, completing the electric push rod 13... When the outrigger assembly 131 is retracted, the upper limit seat 131 will be screwed into the upper U-shaped seat 121. Then, press the circular pressing block 173 on the upper limit seat 131 and insert the cylindrical pin 16 through the upper limit seat 131 and the upper U-shaped seat 121. Then, release the circular pressing block 173 so that the end of the limiting block 176 is inserted into the annular groove 161. This completes the quick limiting of the electric push rod 13 in the horizontal state. Finally, rotate the transverse support column 12 to the side of the self-loading and unloading emergency generator 2 to complete the quick retraction of the outrigger assembly 1 when it is not working, improving the convenience of use and the efficiency of the layout.

[0032] In this embodiment, preferably, the bottom end of the spring 172 abuts against the top surface of the circular pressing block 173, and the top end of the spring 172 abuts against the inner wall of the cylindrical pressing groove 171.

[0033] In this embodiment, preferably, the other side surfaces of the upper limit seat 131 and the lower limit seat 132 are each provided with a through hole for the limiting block 176 to pass through, and the other side surfaces of the upper limit seat 131 and the lower limit seat 132 are each provided with a through hole for the pressing rod 174 to pass through.

[0034] In this embodiment, preferably, a bottom support plate is also installed at the bottom end of the bottom support leg 14. The bottom support plate is in contact with the ground to ensure stable support.

[0035] In this embodiment, preferably, both the upper U-shaped seat 121 and the lower U-shaped seat 122 are U-shaped when viewed from the side, so that the upper limit seat 131 can be smoothly screwed into the inner side of the upper U-shaped seat 121, and the lower limit seat 132 can be smoothly screwed into the inner side of the lower U-shaped seat 122.

[0036] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
