[0010] A plurality of counterbores are provided on both sides of the support rod, and the first support block and the second support block are respectively provided with matching screw holes. The connection and disassembly are convenient.

[0011] The reinforcing block is a trapezoidal structure with good strength and long service life.

[0012] The first support block and the second support block are formed by casting, have good strength, and save machining process.

[0013] The following beneficial effects can be achieved by using the utility model:

[0014] 1. The supporting square plates on both sides are changed to one-piece forming, and the middle rectangular tube is changed to sheet metal bending process, and then assembled together with screws.

[0015] 2. The support blocks on both sides are integrally formed by casting, eliminating the need for machining.

[0024] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-6 As shown, the utility model is a support rail for lifting a door frame.

[0026] The support bracket of the lifting gantry in this embodiment includes a support rod 1. The support rod 1 has a structure with an opening on one side. A first support block 2 and a second support block 3 are detachably connected to both sides of the support rod 1 respectively. The first support block 2 and the second support block 3 are symmetrically arranged facing each other, and the first support block 2 and the second support block 3 are attached to the inner side and both sides of the opening of the support rod 1. The first support block 2 and the second support block 3 are respectively composed of a fixed block 21 and a connecting block 22. The fixed block 21 is surrounded by reinforcing blocks on both sides and a connecting plate in the middle. The size of the reinforcing block at the end of the connecting block 22 is larger than the inner size of the opening of the support rod 1. The outer shape of the connecting block 22 is larger than the outer shape size of the support rod 1, and the connecting block 22 is a square structure with rounded corners at the four corners. A plurality of holes are provided on the connecting block 22 for connection and fixation.

[0027] Further, the support rod 1, the first support block 2, and the second support block 3 are respectively integral structures. The support rod 1 adopts laser cutting and bending processes. After assembly, the required accuracy can be achieved without machining on a machine tool.

[0028] Further, the support rod 1 is a "U" - shaped structure, and the connection part has a circular arc transition.

[0029] Further, a plurality of counter - sunk holes 11 are provided on both sides of the support rod 1, and the first support block 2 and the second support block 3 are respectively provided with matching screw holes. The counter - sunk hole structure can sink the head of the connecting screw inside the support rod 1.

[0030] Further, the reinforcing block is a trapezoidal structure, which effectively strengthens the structure.

[0031] Furthermore, the first support block 2 and the second support block 3 are formed by casting, which ensures the outer shape and dimensions.

[0032] When the support bracket of this lifting gantry is in use, only the connecting blocks 22 at both ends need to be fixed to the corresponding positions.

[0033] The above is the preferred embodiment of the present invention, which does not limit the protection scope of the present invention. For those skilled in the art, the deformations and improvements made according to the design concept of the present invention should be regarded as within the protection scope of the present invention.
