However, in actual use of the above patent, when heavy materials are placed on the upper end of the pressure plate, it is difficult for the staff to push the beam. Usually, the material needs to be unloaded first before the beam can be moved, which is inconvenient to operate.
[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an assembly device for the open pipe welding base of the marine diesel engine frame is provided, in order to achieve a more practical purpose. Utility Model Content

DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0022] Example 1: Please refer to Figure 1-5 The utility model provides an assembly device for an open pipe welding base of a marine diesel engine frame, comprising a support rod 100, a cross beam 101, a movable support assembly 102, and a base 103. A motor 110 is fixedly installed on one side of the support rod 100, and the power output end of the motor 110 rotates and penetrates into the support rod 100. A gear 111 is fixedly installed on the deep end of the motor 110, and the gear 111 is rotatably arranged inside the support rod 100. A rack 112 is fixedly installed on the upper end surface of the cross beam 101, and the gear 111 and the rack 112 are meshed and connected. A threaded rod 113 is rotatably installed on one side of the support rod 100, and the deep end of the threaded rod 113 movably contacts the tooth groove of the gear 111. A rotating block 114 is fixedly installed on the other end of the threaded rod 113, and a control panel 115 is fixedly installed on the outer side of the support rod 100.
[0023] Working principle: When in use, the motor 110 is started by controlling the control panel 115, and the motor 110 drives the gear 111 to rotate. When the gear 111 rotates, it drives the meshing rack 112 to move, and the rack 112 drives the beam 101 to move on the support rod 100. When the beam 101 is adjusted to a suitable position, the threaded rod 113 is rotated by the turning block 114, so that the threaded rod 113 is stuck in the corresponding groove of the gear 111, thereby fixing the position of the beam 101 after moving.
[0024] Embodiment 2:
[0025] The difference between the second embodiment and the first embodiment is that: a guide block 121 is fixedly installed on the inner side of the support rod 100, a slide groove corresponding to the guide block 121 is opened at the bottom of the crossbeam 101, a guide rod 122 is fixedly installed on the inner wall of the slide groove of the guide block 121, the guide rod 122 slides through the guide block 121, the number of guide rods 122 is set to two, a scale value 120 is set on the side of the crossbeam 101, an anti-slip convex block is set on the outer side of the rotating block 114, a groove is opened on the upper end surface of the guide block 121, and a uniform fixed installation is installed in the groove. There are four rotating shafts 123, and rollers 124 are rotatably installed on the outer sides of the rotating shafts 123. The rollers 124 rotate to resist the crossbeam 101. When in use, the movement of the crossbeam 101 is guided by the guide block 121 and the guide rod 122. When the crossbeam 101 moves, the rotating shaft 123 will rotate with the friction of the crossbeam 101. The distance moved by the crossbeam 101 on the support rod 100 is judged by the scale value 120, and the friction between the rotating block 114 and the staff's hand is increased by the anti-slip bump.
[0026] Finally: The above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
