Problems solved by technology

[0006] (1) Since the overturning chain is flexible, the center of gravity of the track beam is constantly changing during the overturning process of the track beam on the overturning chain, so the track beam shakes a lot on the overturning chain and has a large impact force; the track beam needs to be fixed during assembly. That is to say, only the crawler beam can be assembled when it does not move on the flip chain, and the track beam of the flexible chain is easy to shake when assembling, and it can only be turned over, and the assembly cannot be realized, let alone the use of multi-axis tightening machines; It takes a period of time from shaking to standing still; and during assembly, the operator accidentally touches the track beam or external force touches the track beam, which will make the track beam shake again, so the disadvantage of this displacement method is that the track beam is on the chain Easy to shake, not conducive to assembly, and low work efficiency
[0007] (2) When the chain is in motion, due to the heavy weight of the track beam itself, sliding between the track beam and the chain is easy to occur, causing the track beam to be scratched and bumped. Seriously affect product quality
[0008](3) There are supporting rollers on the track beam, the supporting rollers are arc-shaped, the distance between adjacent supporting rollers is small, and the distance between each supporting roller The spacing between the chains and rollers is different, and the shaking is large when turning over at the same time, causing misalignment between the chain and the rollers, seriously affecting the turning efficiency and causing safety hazards
[0009] It can be said that the current track beam overturning mainly adopts the driving overturning operation method, the technical level is backward, and there are potential safety hazards for personnel and driving
There is an impact in this flipping method, which is likely to cause bumps, scratches and deformation of the crawler beam, leaving quality problems for subsequent processes
As the output increases year by year, the use of the crane to turn over and shift takes a long time to travel, which causes the crane to fail to meet the normal lifting workload and restricts the improvement of the overall production capacity.

Embodiment Construction

[0043] The working principle and specific structure of the connection plate assembly proposed according to the present invention and the double-sided assembly positioner with the connection plate assembly will be described in detail below in conjunction with the accompanying drawings.

[0044] The principle of the bilateral assembly positioner of the present invention mainly adopts mechanical transmission. The connection between the crawler beam 2 and the double-sided assembly positioner is divided into two steps: the first step is to connect the connection plate assembly 6 with the drive frame 21 of the track beam 2, the main purpose is to reduce the assembly time on the positioner and improve the turnover The utilization rate of the machine; the second step is to connect the connecting plate assembly 6 with the rotating base 1 of the positioner, and then connect the moving base 4 with the fork end 22 of the crawler beam 2 to achieve the purpose of fixing the crawler beam 2. ...

Abstract

The invention discloses a double-sided assembly positioner, comprising a connecting plate assembly, which includes a main shaft (62), a fixed connecting plate (65) fixedly connected to the main shaft (62), a movable connecting plate (63) and a fixed connecting plate (65) Removably connected, the movable connecting plate (63) is detachably connected with the crawler beam driving frame (21), and the two ends of the main shaft (62) can be respectively engaged on the extension arm (12) of the rotating base (1), and the rotating A pair of extension arms (12) of the base (1) is provided with grooves (15), and the shaft steps (67) at both ends of the main shaft (62) are fixedly connected to the grooves (15) by threaded pressure plates (14). Among them, the mobile base (4) is installed on a pair of first rails (7), and the connecting end (41) of the mobile base (4) is detachably connected with the fork end (22) of the track beam. The double-sided assembly positioner can overcome the problems existing in the prior art, and has the advantages of convenient loading and unloading of workpieces, saving production area, and more stable turning.

Description

technical field [0001] The invention relates to a displacement device, in particular to a displacement device for large parts, for example, a displacement device for assembling a crawler beam of a crawler crane. Background technique [0002] Positioner refers to a special machine that can change the original position of the workpiece, that is, flip the workpiece to the required position, so that the operator can weld, assemble or operate. A positioner is sometimes called a flipper. [0003] At present, there are mainly two types of crawler beam positioners, one is an L-shaped positioner, which is mainly composed of a base 82, a gusset bracket 84, a driving cylinder 83, a hydraulic station, etc., and flips the track beam 81. Such as Figure 8 Shown; The other is a chain positioner, which is mainly composed of a motor reducer 91, a sprocket 93, a turning machine main frame 94, a turning chain 92 and other parts, such as Figure 9(1) , 9(2) and 9(3). [0004] The first type...
