[0007] Further, the both sides of portal frame are fixed with vertical slide rods, the vertical both sides of hanging plate are fixed with slide blocks, and the slide blocks move on the slide rods.

[0008] Furthermore, rotatable auxiliary wheels are respectively installed on the left and right sides of the bottom of the frame, and the auxiliary wheels are used to contact the inner wall of the multi-wire cutting machine.

[0009] Compared with the prior art, the advantages of this utility model are that the roller grooves on the forks can accurately position and support the rollers, making the roller replacement process simpler and enabling one-time disassembly or installation, thus improving operational efficiency; the bottom of the frame is equipped with rotatable auxiliary wheels for contacting the inner wall of the multi-wire cutting machine, reducing friction between the frame and the inner wall of the multi-wire cutting machine, allowing the frame to smoothly and accurately enter the bottom of the multi-wire cutting machine, further improving the stability and accuracy of operation. Attached Figure Description

[0010] Fig. 1 This is a reference diagram showing the usage state of this utility model;

[0011] Fig. 2 This is a three-dimensional structural diagram of the present invention. Detailed Implementation

[0012] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0013] like Figs. 1-2 As shown, a trolley for assisting in changing rollers on a multi-wire cutting machine includes a frame 1. A wheel seat 2 is rotatably mounted at the front end of the frame 1, and a drive wheel 3 is fixed to the bottom of the wheel seat 2. A push rod 4 is hinged to the upper end of the wheel seat 2. A mast 5 is vertically fixed in the middle of the frame 1. A driven wheel 6 is fixedly mounted at the bottom of the frame 1. Rotatable auxiliary wheels 9 are respectively mounted on the left and right edges of the bottom of the frame 1. The auxiliary wheels 9 are used to contact the inner wall of the multi-wire cutting machine to reduce the friction between the frame 1 and the inner wall of the multi-wire cutting machine, so that the frame 1 can smoothly and accurately enter the multi-wire cutting machine. A loading mechanism 7 is slidably connected to the mast 5. The loading mechanism 7 includes a hanging plate 71 and two sets of forks 72, and the forks 72 are fixedly connected to the hanging plate. Two sets of forks 72 are arranged vertically on the mast 71. Each fork 72 has at least one roller groove 721 for positioning and supporting the roller. Vertical slide rods 51 are fixed on both sides of the mast 5. Slider blocks 73 are fixed on both vertical sides of the hanging plate 71. The sliders 73 move on the slide rods 51, so that the hanging plate 71 and the mast 5 slide vertically. A hanging plate lifting drive mechanism 8 is provided on the frame 1. The hanging plate lifting drive mechanism 8 includes a lead screw 81 rotatably connected to the mast 5 and a motor 82 fixedly installed on the frame 1. The lead screw 81 is vertically arranged. The motor 82 drives the lead screw 81 to rotate through an angle coupling 83. A connecting seat 74 is fixedly provided on the hanging plate 71 and is screwed to the lead screw 81.
