Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention can be embodied in many different forms other than those specifically described herein, and it will be apparent to those skilled in the art that similar modifications can be made without departing from the spirit and scope of the invention, and it is therefore not to be limited to the specific embodiments disclosed below.

As shown in fig. 1, the utility model discloses a horizontal 90 degrees elbows of crane span structure with adjustable, including setting up easy broken line 1 on the bottom plate of horizontal 90 degrees elbows of crane span structure, easy broken line 1 includes N perpendicular easy broken line and N horizontal easy broken line, and N more than or equal to 2, two liang of mutually perpendicular between perpendicular easy broken line and the horizontal easy broken line, between two adjacent perpendicular easy broken lines and between two adjacent horizontal easy broken lines parallel to each other and certain distance L in interval, distance L equals the height of elbow curb plate.

In one embodiment, the N vertical easy folding lines, the N horizontal easy folding lines and the right-angled sides outside the elbows are divided to form a large square of an N x N grid, the large square comprises N x N small squares, and the side length of each small square is L.

In one embodiment, the bottom plate of the horizontal 90-degree elbow of the adjustable bridge frame is further provided with a knockout hole 2, the knockout hole 2 comprises a horizontal knockout hole and a vertical knockout hole, the N small squares on the diagonal line of the large square are all provided with the horizontal knockout hole, the vertical knockout hole is further arranged right above the horizontal knockout hole, and specifically, the vertical knockout hole can be arranged above the horizontal easy-to-break line, so that the horizontal knockout hole can be overlapped with the vertical knockout hole after being bent, and the joint is connected with the vertical knockout hole through the horizontal knockout hole and the vertical knockout hole by a fixing bolt after being bent.

Therefore, after the two outer sides are folded and cut, the horizontal knocking-off holes and the vertical knocking-off holes which are matched with each other can be overlapped to form the knocking-off holes on the right angle shown in the leftmost lower corner of the drawing 1, and joints are connected through the knocking-off holes by fixing bolts after the bending so as to finish the mutual fixing of the two right-angle sides.

In order to realize the connection between the 90-degree elbow and other straight bridge plates, a horizontal knockout hole and a vertical knockout hole are respectively arranged at the edge end of the bottom plate in the horizontal direction and the edge end of the bottom plate in the vertical direction. In addition, the material of the horizontal 90-degree elbow of the adjustable bridge frame is an aluminum alloy plate or a steel plate, so that an easy folding line can be conveniently formed.

In one embodiment, the distance L is 100mm and N is 4. As shown in fig. 1, taking the horizontal easy folding line as an example, the minimum interval between the 200mm fold 1.1, the 300mm fold 1.2, the 400mm fold 1.3 and the 500mm fold 1.4 formed by the four horizontal easy folding lines is 100mm, so that 90-degree elbows with adjustable width range of 200-600 mm are formed, and when the width is selected to be 600mm, no cutting and folding operation is needed. After being folded, the bent pipe can form a bent pipe with the width and the height of 200 x 100mm, 300 x 100mm, 400 x 100mm and 500 x 100mm, and the side plate of the bent pipe is fixed on the bottom plate which is provided with the easy folding line.
