Technical Field
[0001] The utility model relates to the technical field of special equipment for assembling a sheet-type standard section lifting block, in particular to welding equipment for a sheet-type standard section lifting block. Background Art
[0002] When the tower crane is jacking, the jacking beam is connected to the jacking block of the standard section through the pins on both sides, and the jacking beam is connected to the sleeve frame through the oil cylinder. The jacking sleeve frame is installed on the outside of the standard section, and the sleeve is equipped with 8 sets of rollers to ensure that the sleeve frame moves up and down on the standard section. The jacking system of the tower crane includes jacking beams, standard sections, jacking blocks, oil cylinders, sleeve frames and other components. The current problems are mainly concentrated on the welding device of the standard section jacking block, and there are errors and inaccurate assembly caused by manual marking or simple marking molds.

DETAILED DESCRIPTION
[0023] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.
[0024] like Figure 1As shown, the utility model proposes a sheet-type standard section lifting block welding equipment, including a drive motor 1. The core part of the equipment is the drive motor 1, which is located in the center of the equipment and is responsible for providing driving force to achieve double-sided welding of the standard section lifting block. On one side of the drive motor 1, a connecting sleeve 6 is installed, which is a key component for achieving connection and coordinated movement of various components. On one side of the connecting sleeve 6, a main frame weldment 15 is installed, which is the supporting frame of the entire structure. A longitudinal tensioner 7, a main chord and lifting positioning block 18, a main chord angle steel clamp 11 and a longitudinal positioning block 16 are installed in sequence above the main frame weldment 15. The longitudinal tensioner 7 installed above the main frame weldment 15 is used to securely position and clamp the workpiece longitudinally during welding; the main chord and lifting positioning block 18 is located at the core position of the lifting system, is responsible for leading the upward movement during welding, and ensures accurate positioning through the threaded positioning pin 8. It is worth noting that there are four main chord and lifting positioning blocks 18, two of which correspond to each other and are placed relative to each other, which means that during welding, these four blocks work together to provide better support and positioning. This relative design helps to balance the force and pressure during welding, thereby ensuring the consistency and accuracy of the welding results; the installation and adjustment of the threaded positioning pin 8 is a key link in this welding equipment. The threaded positioning pin 8 is fastened to the main chord and the lifting positioning block 18 by the locking nut 10, and the setting of the gasket 10 helps to ensure a firm connection between the threaded positioning pin 8 and the locking nut 10. This design ensures the reliability and stability of the main chord and the lifting positioning block 18 during the welding process, and achieves the purpose of fixing the positioning of the standard section lifting block and preventing welding deformation; the main chord angle steel clamp 11 is another key component, which is connected to the brackets on both sides of the main frame weldment 15 through the clamp turn pin 12, and the clamp turn pin 12 and the bracket are distributed on both sides of the main frame weldment 15 of the main frame weldment (15), respectively. There are two pieces, which are used for the separate assembly and welding of two symmetrical standard section main chords and lifting blocks, and maintain stability during the welding process; the main chord angle steel clamp 11 is connected to the bracket through the clamp turn pin 12. This connection method allows the clamp to move during the welding process. This design takes into account the need to clamp and release the main chord during the welding process, so that the movement of the clamp is more flexible and controllable. At the same time, the longitudinal positioning block 16 further strengthens the positioning of the workpiece in the longitudinal direction to ensure the accuracy and consistency of welding. On one side of the equipment, the presence of the rotating shaft 17 increases the stability of the entire system. The outer periphery of the rotating shaft is connected to a bearing seat 13, and a bearing seat bracket 14 is arranged below, which further reduces the friction during movement and ensures the smooth rotation of the rotating shaft, which helps to increase the life of the equipment. The outer periphery of the rotating shaft 17 is provided with a bearing seat 13, and the bearing seat bracket 14 is arranged below the bearing seat. This setting is intended to provide good support and guidance for the rotating shaft, reduce the friction of the rotating shaft during movement, and ensure its smooth rotation.The design of the bearing seat and bracket takes into account the impact on the overall stability and durability of the equipment, so that the equipment can maintain high efficiency and reliability during long-term operation. In order to ensure the stable support of the drive motor, the motor bracket 2 is set under the equipment through bolts 3 and nuts 5, and washers 4 are set between the bolts and nuts to ensure the tightness and stability of the connection.
