Description

Technical Field

[0001] This utility model relates to the field of plate unit welding and assembly technology, and in particular to a step-type plate unit loading and unloading device. Background Technology

[0002] The bridges now use steel box girder bridge deck panel units. The panel unit includes a steel panel and U-ribs. When manufacturing the panel unit, the two web plates on both sides of the U-rib need to be welded to the steel panel along the longitudinal corner seams.

[0003] Before performing internal and external welding, the U-ribs and steel panels need to be positioned, assembled, and spot-welded before being sent to the external welding system and internal welding system for welding.

[0004] Currently, most board unit assembly machines use mobile gantry assembly machines, which use fixed supports for the board units to be assembled. The mobile gantry assembly machine positions, presses, and spots welds the board units from one end to the other. This type of pressing can lead to increased deformation of the board units.

[0005] Therefore, there is an urgent need to design a material loading and unloading device that can achieve assembly line-style loading and unloading, and work in conjunction with plate unit pressing equipment to position, press and spot weld the plate units, thereby reducing deformation. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a stepping plate unit loading and unloading device. The technical solution is as follows: A step-type plate unit feeding device includes multiple fixed support columns, multiple step-moving components, a step-power device, and a track. The bottoms of the multiple fixed support columns are detachably installed on the foundation, and the tops of the multiple fixed support columns form a fixed support surface for supporting the bottom of the steel panel of the plate unit to be assembled. The step-moving components include a step-moving trolley and a hydraulic lifting device. The step-moving trolley moves on the track. The end-to-end of the step-moving trolleys of the multiple step-moving components are connected by connecting rods. The base of the hydraulic lifting device is detachably installed on the top of the step-moving trolley. The base of the step-power device is installed on the foundation, and its telescopic end is connected to the side of the step-moving trolley. The track is installed on the foundation. When the telescopic end of the step-power device extends or retracts, it drives the step-moving trolley to perform a step-like reciprocating motion in the track direction.

[0007] Optionally, when the stepping plate unit feeding device performs the stepping feeding action, the hydraulic lifting devices of multiple stepping moving components rise synchronously to support the bottom of the steel panel of the plate unit to be assembled away from the top of multiple fixed support columns. The stepping moving trolleys of multiple stepping moving components move synchronously to the designated position according to the stepping control command. The hydraulic lifting devices of multiple stepping moving components descend synchronously to place the spot welding position of the assembly plate unit in the assembly position of the gantry rib plate assembly machine.

[0008] By adopting the above technical solution, the top fixed support surface of multiple fixed support columns is the support foundation of the plate unit. When stepping movement is required, the hydraulic lifting devices of multiple stepping movement components need to be started simultaneously to lift the plate unit to be assembled away from the fixed support surface. It is also necessary to ensure that the bottom of the plate unit is higher than the assembly position of the gantry rib plate assembly machine. Then, the reciprocating motion of the stepping power device is used to realize the stepping feeding action of the plate unit. Since the stepping plate unit unloading device adopts the same configuration as the stepping plate unit loading device, it can realize assembly line-style stepping loading and unloading.

[0009] Optionally, the stepping power unit includes a mounting base and a power component. The mounting base is detachably mounted on the foundation and located in the middle of the two rails of the track. The cylinder of the power component is detachably mounted on the mounting base. The piston rod end of the power component is connected to the side of one of the stepping moving trolleys of a plurality of stepping moving components. When the piston rod of the power component extends or retracts, it drives the stepping moving trolley to perform stepping reciprocating motion in the track direction.

[0010] Optionally, the power component is a hydraulic cylinder.

[0011] By adopting the above technical solution, a single power component is used to drive the stepping trolley in reciprocating linear motion on the track, providing high driving force and being economical and reliable. Due to the assembly plate unit at the top, other trolleys will perform synchronous reciprocating movements. Of course, electric cylinders or other power components can also be used as the power component depending on the application scenario.

[0012] In summary, this utility model has at least one of the following beneficial technical effects: This utility model provides a stepping plate unit loading and unloading device. The top fixed support surface of multiple fixed support columns is the support base of the plate unit. When stepping movement is required, the hydraulic lifting devices of multiple stepping movement components need to be started simultaneously to lift the plate unit to be assembled away from the fixed support surface. The bottom of the plate unit to be assembled must be higher than the assembly position of the gantry rib plate assembly machine. Then, the reciprocating motion of the stepping power device is used to realize the stepping loading action of the plate unit. Since the stepping plate unit unloading device adopts the same configuration as the stepping plate unit loading device, it can realize assembly line-style stepping loading and unloading.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings.

[0016] This utility model discloses a step-type plate unit loading and unloading device.

[0017] Reference Figure 1 - Figure 7 Example 1: A stepping plate unit feeding device includes multiple fixed support columns 11, multiple stepping moving components 12, a stepping power device 13, and a track 101. The bottoms of the multiple fixed support columns 11 are detachably installed on the foundation, and the tops of the multiple fixed support columns 11 form a fixed support surface for supporting the bottom of the steel panel of the plate unit 100 to be assembled. The stepping moving component 12 includes a stepping moving trolley 121 and a hydraulic lifting device 122. The stepping moving trolley 121 is located on the track. The multiple stepping moving components 12 are connected end to end by connecting rods on the track 101. The base of the hydraulic lifting device 122 is detachably installed on the top of the stepping moving trolley 121. The base of the stepping power device 13 is installed on the foundation, and the telescopic end is connected to the side of the stepping moving trolley 121. The track 101 is installed on the foundation. When the telescopic end of the stepping power device 13 extends or retracts, it drives the stepping moving trolley 121 to perform stepping reciprocating motion in the direction of the track 101.

[0018] In Example 2, when the stepping plate unit feeding device performs the stepping feeding action, the hydraulic lifting devices 122 of multiple stepping moving components 12 rise synchronously to support the bottom of the steel panel of the plate unit 100 to be assembled away from the top of multiple fixed support columns 11. The stepping moving trolleys 121 of multiple stepping moving components 12 move synchronously to the designated position according to the stepping control command. The hydraulic lifting devices 122 of multiple stepping moving components 12 descend synchronously to place the spot welding position of the assembly plate unit 100 in the assembly position of the gantry rib plate assembly machine.

[0019] The top fixed support surface of multiple fixed support columns 11 is the support base of plate unit 100. When stepping movement is required, the hydraulic lifting device 122 of multiple stepping movement components 12 needs to be started simultaneously to lift the plate unit 100 to be assembled away from the fixed support surface. The bottom of the plate unit 100 must be higher than the assembly position of the gantry rib plate assembly machine. Then, the reciprocating action of the stepping power device 13 is used to realize the stepping feeding action of the plate unit 100. Since the stepping plate unit unloading device adopts the same configuration as the stepping plate unit loading device, it can realize assembly line-style stepping loading and unloading.

[0020] In embodiment 3, the stepping power device 13 includes a mounting base 131 and a power component 132. The mounting base 131 is detachably mounted on the foundation and located in the middle of the two rails of the track 101. The cylinder of the power component 132 is detachably mounted on the mounting base 131. The piston rod end of the power component 132 is connected to the side of one of the stepping moving trolleys 121 of the plurality of stepping moving components 12. When the piston rod of the power component 132 extends or retracts, it drives the stepping moving trolley 121 to perform stepping reciprocating motion in the direction of the track 101.

[0021] In Example 4, the power component 132 is a hydraulic cylinder.

[0022] Here, a single power component 132 is used to drive the stepping trolley 121 to reciprocate linearly on the track 101, providing high driving force and being economical and reliable. Due to the assembly plate unit 100 at the top, the other trolleys 121 will perform synchronous reciprocating movements. Of course, depending on the application scenario, an electric cylinder or other power components can also be used as the power component 132.

[0023] Two sets of step-type plate unit feeding devices with the same structure are arranged in the middle to form an assembly production line. The plate unit 100 to be assembled includes a steel panel 1001 and multiple ribs 1002. The multiple ribs 1002 are arranged at equal intervals on the steel panel 1001. Multiple fixed welding points are set at equal intervals in the direction of the ribs 1002. Each row of fixed welding points forms a step-type assembly position. The production line includes a step-type plate unit feeding device, a gantry-type rib assembly machine, and a step-type plate unit unloading device. The step-type plate unit feeding device adopts a reciprocating motion. The plate unit 100 to be assembled is fed into the gantry rib plate assembly machine in a stepping manner. Each time, the gantry rib plate assembly machine positions and presses the steel panel and multiple ribs of the plate unit 100 to be assembled at the stepping assembly position. After spot welding and fixing, it continues to step to the next stepping assembly position. The plate unit 100 to be assembled continues to move forward into the stepping plate unit feeding device. The stepping plate unit unloading device uses the same reciprocating stepping method as the stepping plate unit feeding device to move the plate unit 100 to be assembled out to form the plate unit stepping moving assembly machine production line.

[0024] The steel panel 1001 is hoisted onto the step-type plate unit feeding device, and multiple ribs 1002 are arranged on the steel panel 1001 for pre-spot welding for initial positioning. The step-type plate unit feeding device uses a reciprocating stepping method to feed the plate unit 100 to be assembled into the gantry rib assembly machine. Each time the gantry rib assembly machine positions and presses the steel panel and multiple ribs of the plate unit 100 to be assembled at the step-type assembly position, after the first step-type assembly position is spot welded and fixed, it continues to step forward and is conveyed into the step-type plate unit unloading device. The step-type plate unit unloading device uses the same stepping action as the step-type plate unit feeding device to realize the unloading action of the plate unit 100 to be assembled after positioning, pressing and spot welding.

[0025] It realizes automated board unit loading, positioning and pressing and unloading actions except for spot welding. No crane support is required in the board unit step-moving assembly line area. Each positioning and pressing is a synchronous positioning and pressing of a row of fixed welding points to form a step assembly position, avoiding the deformation risk caused by using a single position for fixed-point pressing.

[0026] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made according to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
