Abstract

The utility model relates to a steel structure assembly welding stabilizer, which belongs to the manufacturing technology area of the building material machinery. The stabilizer is mainly composed of a stander (5) with a feeding roll table (4), a cylinder (9) with a rack (8) positioned on the feeding roll table (4), a main shaft (6) positioned on the stander (5) with a gear (7) and a swinging arm (3) on both sides, and a depended wheel (1) arranged on the top of the swinging arm (3). The rack (8) and the gear (7) is engaged in transmission, the main shaft (6) is arranged obliquely and the angle of slope Alpha between the main shaft (6) and the plane of the stander (5) is 30 to 60 degrees. The utility model has a reasonable design. The main shaft is positioned obliquely, and the swinging arm is positioned vertically with the main shaft, which makes the swinging arm cling to the feeding roll table before the steel structure workpieces are welded in assemblage, thus efficiently ensuring that the steel structure workpiece will not collide with the main shaft during the process of hoisting and carrying, and the service life of the equipment is greatly improved accordingly.

Description

The vertical position welding of steel construction group connects erection device

Technical field

The utility model relates to the vertical position welding of a kind of steel construction group and connects erection device, belongs to the manufacturing technology field of building mechanical equipment.

Background technology

When the vertical position welding of steel construction group connects, weld assembly unit processing after workpiece need be centralized.Existing erection device is generally main shaft is vertical placement, swing arm horizontal positioned with respect to rollgang version, swing arm slides up and down along main shaft according to the workpiece size and regulates its corresponding height, provide power by oil cylinder, rotate swing arm, reach to clamp and set upright purpose by linkage.Mainly there is following defective:

1, exceed about 1.5 meters of rollgangs owing to main shaft is general vertical, therefore in process, the steel construction workpiece is when the lifting carrying, and frequent and main shaft bumps, and damages main shaft, shortens the service life of equipment greatly.

2, adopt a series of linkage, complex structure, production efficiency is low, and operating accuracy is also undesirable.

Summary of the invention

The purpose of this utility model provides a kind of reasonable in design, and is simple in structure, and reliable operation is easy to operate, and the steel construction group vertical position welding of long service life connects erection device.

The utility model is that the vertical position welding of steel construction group connects erection device, comprises the frame of being with rollgang, it is characterized in that rollgang is provided with the oil cylinder of band tooth bar, and frame is provided with two ends respectively with the main shaft of gear and swing arm, the rack and pinion engaged transmission; Described main shaft is tiltedly to be sidelong to be put, and the inclined angle alpha between main shaft and the horizontal plane of frame is 30～60 °.During use, provide power,, swing arm is risen, clamp the purpose of setting upright the steel construction workpiece thereby reach by gear, tooth bar engagement rotating spindle by oil cylinder.

The top of described swing arm also can be provided with roller.

The utility model compared with prior art has following outstanding advantage and good effect:

1, because main shaft adopts tiltedly to be sidelong puts, swing arm is vertical with main shaft places, the vertical position welding of steel construction workpiece group is connect before, swing arm is adjacent to rollgang, guarantee that effectively the steel construction workpiece in the lifting handling process, can not bump with main shaft, thus the service life of improving equipment greatly.

2, employing wheel and rack engaged transmission form is simple and reliable for structure, improves the operating accuracy of steel construction workpiece greatly.

Description of drawings

Fig. 1 is an overall structure front view of the present utility model;

Fig. 2 is an A-A face structural representation shown in Figure 1;

Fig. 3 is a working state schematic representation of the present utility model.

Among the figure, 1 is roller, and 2 is the steel construction workpiece, and 3 are swing arm, and 4 is rollgang, and 5 is frame, and 6 is main shaft, and 7 is gear, and 8 is tooth bar, and 9 is oil cylinder.

The specific embodiment

The utility model mainly by the frame 5 of band rollgang 4, place on the rollgang 4 band tooth bar 8 oil cylinder 9, place two ends on the frame 5 respectively with the main shaft 6 of gear 7 and swing arm 3, place roller 1 formation such as grade at swing arm 3 tops, tooth bar 8 and gear 7 engaged transmission, main shaft 6 is tiltedly to be sidelong to be put, and the inclined angle alpha between main shaft 6 and frame 15 horizontal planes is 30～60 °.

Frame 5 and main shaft 6, swing arm 3 are used bearings each other with roller 1, and rotation flexibly; Main shaft 6 is connected firmly with flat key respectively each other with gear 7, swing arm 3; Rollgang 4 is connected firmly with bolt each other with oil cylinder 9; Frame 5 supports with oilless bearing each other with tooth bar 8; Oil cylinder 9 is connected with tooth bar 8 usefulness hinges.

Equipment is before startup, swing arm 3 is adjacent on rollgang 4 (as shown in Figure 2), when steel construction workpiece 2 lifting is carried on the rollgang 4, start oil cylinder 9 stretching tooth bars 8, the engaged transmission by tooth bar 8 and gear 7 makes main shaft 6 rotations, swing arm 3 is slowly risen, roller 1 in swing arm 3 is close to steel construction workpiece 2 (as shown in Figure 3), simultaneously, and according to the height of steel construction workpiece 2, regulate the position of swing arm 3 and main shaft 6, the position that makes roller 1 be close to workpiece meets the requirements.At this moment, steel construction workpiece 2 is in the operating position of rollgang 4 substantially.Start the steel construction group vertical position welding structure of meeting sb. at the airport, the assembly unit welding after welding is finished, starts oil cylinder 9 compression tooth bars 8, by the engaged transmission of tooth bar 8 with gear 7, makes main shaft 6 rotations, and swing arm 3 slowly descends, and is adjacent on rollgang 4 up to swing arm 3.Repeat above-mentioned action, carry out the welding of next part steel construction workpiece.

Claims

1, the vertical position welding of a kind of steel construction group connects erection device, the frame (5) that comprises band rollgang (4), it is characterized in that rollgang (4) is provided with the oil cylinder (9) of band tooth bar (8), frame (5) is provided with two ends respectively with the main shaft (6) of gear (7) and swing arm (3), tooth bar (8) and gear (7) engaged transmission; Described main shaft (6) is tiltedly to be sidelong to be put, and the inclined angle alpha between main shaft (6) and frame (15) horizontal plane is 30～60 °.
