[0002] At present, during the installation process of large and overweight equipment, jacking equipment is required to assist in the disassembly and installation of large equipment by jacking operations. Existing jacking equipment usually adopts a feeding trolley to deliver the raising blocks from the receiving platform to the pallet of the jacking equipment. However, the current feeding tool adopts hydraulic transmission. However, due to the large adjustment range of the speed of the hydraulic transmission when the raising blocks are transported to the raising block pallet of the jacking equipment during the feeding process, the adjustment accuracy is relatively low. Therefore, it is easy for the raising blocks to be misplaced on the pallet, affecting the accuracy and effect of jacking. Utility Model Content

The plurality of lifting cylinders surround the raising block placement area on the raising block conveying pallet, and the lifting piston rod in each lifting cylinder is connected to the lower surface of the raising block conveying pallet. A ball screw is installed at the bottom of the pallet base, and the two ends of the ball screw are respectively connected to the welcoming platform outside the step-by-step raising and lifting equipment and the lower part of the step-by-step raising and lifting equipment through bearing seats. A transmission device is provided on the ball screw, and the transmission device includes a transmission motor and a transmission transition combination. The transmission motor is connected to the ball screw through the transmission transition combination.

[0005] Furthermore, the transmission transition combination mainly includes a pulley combination and a screw slider. The pulley combination includes a pulley I and a pulley II. Pulley I is installed on the output shaft of the transmission motor, and pulley II is installed on the ball screw. Pulley I is connected to pulley II through a transmission belt. A screw slider is installed on the ball screw. The screw slider is connected to the pallet base through a connecting plate. The transmission motor drives the ball screw to rotate through pulleys I and pulley II. A track wheel is installed at the bottom of the pallet base. After rotation, the ball screw drives the screw slider to slide back and forth horizontally on the ball screw. The screw slider drives the track wheel of the pallet base to slide back and forth horizontally on the rail (15) installed at the bottom of the welcoming platform and the step-by-step raising and lifting equipment. The movement of the pallet base also drives the raising block to transport the pallet to perform horizontal reciprocating motion.

[0006] Furthermore, the transmission motor is configured as a servo motor.

[0007] Furthermore, four lifting cylinders are installed vertically upward in the pallet base, two of which are installed on the front side of the pad placement area, and the other two are installed on the rear side of the pad placement area. The two lifting cylinders installed on the front side are symmetrically arranged with the two lifting cylinders installed on the rear side. The four lifting cylinders push the pad conveying pallet to perform lifting and lowering movements, thereby driving the pads placed on the pad conveying pallet to rise and fall.

[0008] The present invention has the following beneficial effects: after adopting the above technical solution, the present invention adopts a servo motor to drive the raising block conveying tray to transport the raising blocks. Since the speed and position can be precisely controlled, the ball screw can accurately control the position of the raising block conveying tray 2 during the transmission process, so that the raising blocks on the raising block conveying tray can accurately reach the raising block lifting position, thereby improving the accuracy and efficiency of the raising blocks during the jacking process. The two lifting cylinders of the present invention are installed on the front side of the raising block placement area, and the other two lifting cylinders are installed on the rear side of the raising block placement area. The two lifting cylinders installed on the front side are symmetrically arranged with the two lifting cylinders installed on the rear side, so that the raising blocks placed on the raising block conveying tray can be lifted and lowered, thereby making it easier for the raising blocks to move in the front and rear directions and facilitating the lifting of the raising blocks.

A screw slider 8 is installed on the ball screw 5. The screw slider 8 is connected to the tray base 1 through a connecting plate 11. The transmission motor is connected to the tray base 1 through a pulley Ⅰ13. And pulley II 7 drives the ball screw 5 to rotate, and a track wheel 14 is installed at the bottom of the pallet base. Two track wheels 14 are symmetrically installed on both sides of the bottom of the pallet base of this embodiment, and two tracks 15 are installed at the bottom of the welcoming platform and the step-by-step padding and lifting device. The two tracks 15 are symmetrically arranged. After rotation, the ball screw 5 drives the screw slider 8 to slide back and forth horizontally on the ball screw 5. The screw slider 8 drives the track wheels 14 on both sides of the pallet base 1 to slide back and forth horizontally on the two tracks 15 installed at the bottom of the welcoming platform and the step-by-step padding and lifting device. The movement of the pallet base 1 also drives the padding block to convey the pallet 2 horizontally. Reciprocating motion, the transmission motor used in this embodiment is set as a servo motor 12, and four vertically upward lifting cylinders 3 are installed in the tray base 1 of this embodiment, of which two lifting cylinders 3 are installed on the front side of the pad placement area 10, and the other two lifting cylinders 3 are installed on the rear side of the pad placement area 10. The two lifting cylinders 3 installed on the front side are symmetrically arranged with the two lifting cylinders 3 installed on the rear side.

[0014] The use process of the present invention is as follows: when it is necessary to transport the padding block on the welcoming platform to the padding block lifting device position of the step-by-step padding jacking equipment, the servo motor 12 is started, and the output shaft of the servo motor 12 drives the ball screw 5 to rotate through the pulley Ⅰ13, the pulley Ⅱ7 and the transmission belt 9. After rotation, the ball screw 5 drives the screw slider 8 to slide back and forth horizontally on the ball screw 5, and the screw slider 8 drives the track wheels 14 on both sides of the tray base 1 to slide back and forth horizontally on the two tracks 15. The movement of the tray base 1 also drives the padding block conveying tray 2 to make horizontal reciprocating motion. Since the servo motor 12 can realize precise control of speed and position, the ball screw 5 can be accurately controlled during the transmission process. The control pad block conveying pallet 2 is in place so that the pad blocks on the pad block conveying pallet 2 can accurately reach the pad block lifting position. This function cannot be achieved if the oil cylinder is used to control the conveying of the pad block. When the pad block reaches the pad block lifting position, the four lifting cylinders 3 push the pad block conveying pallet 2 to lift upward, and the pad block also rises to the specified position with the pad block conveying pallet 2, and the pad block is also separated from the welcoming platform, so that the pad block can be moved and lifted. When the pad block needs to be conveyed again, the four lifting cylinders 3 drive the pad block conveying pallet 2 to move downward into place, and then the ball screw 5 drives the pad block conveying pallet 2 to enter the welcoming platform for conveying the pad block again.
