Description

Technical Field

[0001] The utility model relates to a high-strength laminated gantry frame. Background Art

[0002] High-pressure equipment such as cold isostatic presses will generate ultra-high pressure during operation, and the pressure is generally more than several thousand tons. The cylinder of the press cannot withstand the high pressure, but the gantry frame bears it. In order to enable the gantry to withstand ultra-high pressure, the traditional practice is: 1. The gantry frame is made of steel plates and made into a grooved structure; 2. High-strength steel wire ropes with a certain preload are wound in the grooves; 3. The outside is covered with a cover. The traditional approach has the following disadvantages: 1. The gantry frame has a long production cycle and high cost; 2. Steel wire winding requires special equipment, and the winding process is complicated and the cycle is long; 3. High-strength steel wire ropes are expensive; 4. The steel wires are superimposed on each other, and gaps between the steel wires and the gantry frame steel plates and between the steel wire layers are inevitable. Summary of the invention

[0003] The utility model provides a high-strength laminated gantry frame in order to solve the problems existing in the prior art.

[0004] The technical solutions adopted in this utility model are:

[0005] A high-strength laminated gantry frame includes steel plate laminates. The steel plate laminates are made of high-strength alloy structural steel. The steel plate laminates are rectangular in structure. A rectangular hole is provided in the center of the steel plate laminate. Several steel plate laminates of the same shape are superimposed on each other and fixedly connected by bolts to form a gantry frame. Pads are fixed on the upper and lower hole walls of the center hole of the gantry frame.

[0006] Furthermore, the thickness of the steel plate laminate is 12-16 mm.

[0007] Furthermore, the steel plate stack is cut and formed at one time by a laser cutting machine.

[0008] The utility model adopts multi-layer laminates instead of wire winding. The traditional wire winding gantry needs to apply a large pre-tightening force to the wire when winding the wire, which makes the processing difficult. The multi-layer laminate gantry does not require wire rope winding, and the laminate strength of high-strength alloy structural steel can reach a tensile strength of more than one thousand, which is not much different from the strength of the wire rope, and the strength of the steel plate is higher than the strength of the traditional gantry frame steel plate, so the size and shape are also roughly the same. It is only necessary to use high-strength bolts and nuts to fix the multi-layer laminates, so the manufacturing difficulty is greatly reduced and the cost is also greatly reduced. Compared with the traditional wire layer winding gantry, gaps will inevitably appear between the steel wire and the gantry frame steel plate and the wire layer, so the laminated gantry has better rigidity. In addition, for large-sized gantries, the weight will be heavier, and the lifting equipment may be limited during hoisting and shipping, while the laminated gantry can be disassembled for shipment and assembled on site. The advantages of the multi-layer laminated gantry are as follows:

[0009] 1) The steel plate is made of high-strength alloy structural steel with high strength and good rigidity;

[0010] 2) The stacked sheets are cut and formed at one time by a fiber laser cutting machine, which is convenient for processing and manufacturing, low cost and short production cycle;

[0011] 3) The stacking gantry is easy and convenient to install, and can be shipped separately and assembled on site. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The utility model is further described below in conjunction with the accompanying drawings.

[0015] like Figure 1 and Figure 2 The utility model discloses a high-strength laminated gantry frame, comprising a steel plate laminate 1, the steel plate laminate is made of high-strength alloy structural steel, the steel plate laminate 1 is a rectangular structure, the thickness is 12-16mm, and is cut and formed at one time by a laser cutting machine. A rectangular hole is provided in the center of the steel plate laminate 1, and a plurality of steel plate laminates 1 of the same shape are superimposed on each other and fixedly connected by bolts to form a gantry frame. The upper and lower hole walls of the center hole of the gantry frame serve as the mounting surfaces of the oil cylinder and the workbench. To ensure smooth installation, a pad 2 is fixed on the upper and lower hole walls of the center hole of the gantry frame. The pad 2 is fixed to the gantry frame by bolts.

[0016] The utility model adopts multi-layer laminates to replace wire winding. The traditional wire winding gantry needs to apply a large pre-tightening force to the wire when winding the wire, which makes the processing difficult. The multi-layer laminate gantry does not require wire rope winding, and only needs to use high-strength bolts and nuts to fix the multi-layer laminates, so the manufacturing difficulty is greatly reduced, and the cost is also greatly reduced. Compared with the traditional wire layer winding gantry, gaps will inevitably appear between the steel wire and the gantry frame steel plate and the wire layer, so the laminated gantry has better rigidity. The advantages of the multi-layer laminated gantry are: the steel plate is made of high-strength alloy structural steel, which has high strength and good rigidity. The laminates are cut and formed at one time by a fiber laser cutting machine, which is easy to process and manufacture, and the production cycle is short. The laminated gantry is easy and simple to install, and can be shipped separately and assembled on site.

[0017] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
