DETAILED DESCRIPTION
[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0017] The utility model of the tapered lamp pole butt welding tool, such as Figure 1 、 Figure 2 and Figure 3 As shown, the base 1 includes a first support 2 and a second support 3. Due to the length of the lamp pole, the base 1 is also relatively long. Specifically, the base 1 can be made of a metal plate or bracket with a length that matches the lamp pole. The first support 2 and the second support 3 are used to support and position the lamp pole. There is an appropriate spacing between the first support 2 and the second support 3 to ensure stable support for the lamp pole.
[0018] A first support groove with a semicircular cross-section is provided on the top of the first support 2. A detachable pressure cover 5 is connected to the top of the first support 2. A semicircular second support groove is provided on the lower surface of the pressure cover 5. The first support groove and the second support groove can enclose a circular cavity. A detachable lower positioning sleeve 7 is provided in the first support groove, and a detachable upper positioning sleeve 8 is provided in the second support groove. The upper positioning sleeve 8 and the lower positioning sleeve 7 enclose a truncated cone-shaped positioning cavity 9. The upper surface of the lower positioning sleeve 7 has a semi-truncated cone-shaped groove body, and the lower surface of the upper positioning sleeve 8 has a semi-truncated cone-shaped groove body. After the lower positioning sleeve 7 and the upper positioning sleeve 8 are docked, they can enclose a truncated cone-shaped positioning cavity 9. The size of the positioning cavity 9 is compatible with the outer dimensions of the clamped section of the conical lamp pole, so that the outer wall of the conical lamp pole can fit the lower positioning sleeve 7 and the upper positioning sleeve 8, increasing the contact area with the lower positioning sleeve 7 and the upper positioning sleeve 8, and ensuring the positioning stability of the lamp pole. The lower positioning sleeve 7 and the upper positioning sleeve 8 are detachable and can be replaced with lower positioning sleeves 7 and upper positioning sleeves 8 having different inner cavity sizes, so as to facilitate the support and positioning of lamp poles with different outer diameters.
[0019] The first support 2 is used to position the welded end of the lamp pole, and the second support 3 is used to support the non-welded end of the lamp pole. The welded end of the lamp pole needs to be kept stable, so the gland 5 and the upper positioning sleeve 8 are used to press the lamp pole tightly. The second support 3 only needs to support the non-welded end of the lamp pole and does not need to be pressed tightly. Specifically, the top of the second support 3 is provided with a third support groove with a semicircular cross section. A detachable support block 6 is provided in the third support groove. The upper surface of the support block 6 is provided with a support cavity 10 with a semicircular cross section. The support cavity 10 is coaxial with the positioning cavity 9. The support cavity 10 is semi-conical in shape and its size is adapted to the outer dimensions of the lamp pole, which can stably support the lamp pole.
[0020] The use process of this utility model is as follows: first remove the gland 5, then use a lifting device to place the lamp pole on the lower positioning sleeve 7 and support block 6, adjust the axial position of the lamp pole so that the outer wall of the lamp pole is in full contact with the lower positioning sleeve 7 and support block 6, then install the gland 5 on the first support 2, and press the lamp pole with the upper positioning sleeve 8. The two lamp poles to be butt-welded are positioned separately using the above method, and after positioning, the welding ends of the two lamp poles are butted together and welding can begin.
[0021] In the present invention, in order to facilitate the disassembly and assembly of the gland 5 , the gland 5 is connected to the first support 2 by screws.
[0022] The lower positioning sleeve 7 and the upper positioning sleeve 8 can be semi-cylindrical with a semicircular cross-section. The outer walls of the lower positioning sleeve 7 and the upper positioning sleeve 8 respectively fit the groove walls of the first support groove and the second support groove. When the diameter of the positioning cavity 9 is small, the lower positioning sleeve 7 and the upper positioning sleeve 8 need to be thicker, heavier, and inconvenient to carry and install. Therefore, the utility model is provided with a plurality of lower connecting ribs 11 on the outer wall of the lower positioning sleeve 7, and the lower connecting ribs 11 are connected to the first support 2 by screws. The lower connecting ribs 11 fit the first support groove, and the lower positioning sleeve 7 adopts a semi-cylindrical with a smaller thickness, which is lighter overall. Similarly, the outer wall of the upper positioning sleeve 8 is provided with a plurality of upper connecting ribs 12, and the upper connecting ribs 12 are connected to the pressure cover 5 by screws.
[0023] To facilitate adjustment of the lamppost's height, the first and second supports 2 and 3 each include a connecting base 13 and a lifting block 14. The connecting base 13 is mounted on the base 1. A vertical guide post 15 is positioned on top of the connecting base 13. The guide post 15 extends through the lifting block 14 and slidably engages with it. The guide post 15 provides guidance and positioning, ensuring stable vertical movement of the lifting block 14. A lifting mechanism 16 is positioned between the lifting block 14 and the connecting base 13. This mechanism can utilize existing equipment, such as a pneumatic cylinder, hydraulic cylinder, or linear motor, to drive the lifting block 14 upward and downward. A first support groove and a third support groove are provided on the upper surface of the lifting block 14.
[0024] In order to facilitate the docking of the welding ends of the two lamp poles, a horizontal guide rail 17 is provided on the base 1, and the first support 2 and the second support 3 are both slidably matched with the guide rail 17, that is, the first support 2 and the second support 3 can slide along the guide rail 17, thereby driving the lamp pole to move axially.
[0025] In order to facilitate the movement of the first support 2 and the second support 3, and to ensure that the first support 2 and the second support 3 move synchronously, and to ensure the stability of the lamp pole during the movement, the first support 2 is connected to the second support 3 through a telescopic rod 18, and the first support 2 and the second support 3 are connected to a driving mechanism 4, which is used to push the first support 2 and the second support 3 to slide along the guide rail 17. The length of the telescopic rod 18 is adjustable, thereby adjusting the distance between the first support 2 and the second support 3, so as to support lamp poles of various lengths. The telescopic rod 18 can be made of an existing telescopic rod. After the length adjustment is completed, the length of the telescopic rod 18 remains stable and will not change automatically. When the driving mechanism 4 pushes the first support 2 or the second support 3 to slide, the first support 2 and the second support 3 can move synchronously.
[0026] The driving mechanism 4 is preferably a hydraulic cylinder.
[0027] 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 the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
