[0028] See also Figure 1 - Figure 6A core-drilling machine support includes a frame 100, a moving wheel 200, a pushing member 300 and a rotating member 400, wherein the frame 100 is used to install the core-drilling machine, a rectangular groove 110 is provided at the bottom of the frame 100, the moving wheels 200 are arranged on both sides of the rectangular groove 110, the pushing member 300 is arranged on one side of the two moving wheels 200, the pushing member 300 is arranged parallel to the inner wall of the rectangular groove 110 and is slidably connected to the inner wall of the rectangular groove, and the rotating member 400 is arranged on the same end side of the two pushing members 300 and is rotatably connected to the frame 100, and the rotating member 400 is used to enable the pushing member 300 to drive the moving wheel 200 to be retracted or extended;

[0029] In this embodiment, the rotating member 400 is rotated clockwise, and the rotating member 400 causes the pushing member 300 to move toward the side of the moving wheel 200 and push the moving wheel 200. The moving wheel 200 rotates clockwise with the rotation connection with the inner wall of the rectangular groove 110 as the center. After the rotating member 400 rotates 90°, the lower part of the moving wheel 200 protrudes from the bottom of the rectangular groove 110 and lifts up the frame 100. Then the rotating member 400 is fixed, and the moving wheel 200 is also restricted. At this time, the frame 100 can be moved and rotated. The parts of this device are installed in a relatively open rectangular groove 110. The operation is simple, the structure is reasonable, and the difficulty of maintenance or replacement is greatly reduced.

[0030] In one embodiment, see Figure 1 - Figure 6 , the frame 100 is U-shaped, and a reinforcing rod 120 is provided in the middle of the frame 100;

[0031] In this embodiment, the reinforcing rod 120 ensures the strength of the frame 100 while maintaining its lightness.

[0032] In one embodiment, see Figure 1 - Figure 6 , the top of the moving wheel 200 is rotatably connected to the top inner wall of the rectangular groove 110;

[0033] In this embodiment, the moving wheel 200 is rotatably connected to the side of the rectangular groove 110 .

[0034] In one embodiment, see Figure 1 - Figure 6, the two pushing members 300 each include a push rod 310, a first connecting rod 320 and a second connecting rod 330, the two push rods 310 are located at both sides of the rectangular groove 110, and the top of the push rod 310 is slidably connected to the top inner wall of the rectangular groove 110, the two first connecting rods 320 are respectively rotatably connected to one end of the two push rods 310, the other ends of the two first connecting rods 320 are respectively rotatably connected to the two moving wheels 200, the two second connecting rods 330 are respectively rotatably connected to the other ends of the two push rods 310, and the other ends of the two second connecting rods 330 are respectively rotatably connected to both ends of the rotating member 400;

[0035] In this embodiment, the push rod 310 is rotatably connected to the moving wheel 200 through the first connecting rod 320. When the push rod 310 moves, the moving wheel 200 can be driven by the first connecting rod 320 to rotate along the connection with the rectangular groove 110 as the center of the circle;

[0036] When the push rod 310 moves toward the moving wheel 200 , the moving wheel 200 is lowered, and when the push rod 310 moves away from the moving wheel 200 , the moving wheel 200 is retracted.

[0037] In one embodiment, see Figure 1 - Figure 6 The rotating member 400 includes a rotating shaft 410, two rotating sleeves 420 and a pressure rod 430. The two ends of the rotating shaft 410 are rotatably connected to the inner walls of the two sides of the rectangular groove 110 and extended to the outside of the two sides of the frame 100. The two rotating sleeves 420 are respectively fixedly sleeved on the two end sides of the rotating shaft 410. The bottoms of the two rotating sleeves 420 are respectively rotatably connected to one end of the two second connecting rods 330. The bottom end of the pressure rod 430 is fixedly connected to the middle of the rotating shaft 410. The middle of the pressure rod 430 is provided with a universal wheel 440. The top of the pressure rod 430 is rotatably connected with an extension rod 450. A clamping groove 130 is opened on one side of the top of the frame 100. One end of the extension rod 450 is adapted to the clamping groove 130.

[0038] In this embodiment, the pressing rod 430 is rotated clockwise, and the pressing rod 430 drives the two rotating sleeves 420 to rotate together through the rotating shaft 410, and the rotating sleeve 420 rotates and pushes the push rod 310 to approach the moving wheel 200 through the second connecting rod 330. The pressing rod 430 is rotated counterclockwise, and vice versa.

[0039] The rotation direction of the extension rod 450 is perpendicular to the rotation direction of the pressure rod 430. The pressure rod 430 rotates clockwise and rotates the extension rod 450 to one side, so that one end of the extension rod 450 is embedded in the positioning groove 130, so that the pressure rod 430 can be fixed and reset. When the pressure rod 430 needs to be reset, the extension rod 450 is rotated first to disengage it from the positioning groove 130.

[0040] In one embodiment, see Figure 1 - Figure 6 The cross section of the rotating shaft 410 is polygonal, which reduces the difficulty of installing the pressure rod 430 and the rotating shaft 410 and improves the torsional resistance of the rotating shaft 410.

[0041] In one embodiment, see Figure 1 - Figure 6 A chamfer 121 is provided at the entrance of the positioning groove 130 , and the chamfer 121 can improve the convenience of inserting the extension rod 450 .

[0042] In one embodiment, see Figure 2 , Figure 4 and Figure 5 The height dimension of the moving wheel 200 is greater than the depth dimension of the rectangular groove 110. When the push rod 310 pushes the moving wheel 200, it is not necessary to make the moving wheel 200 completely perpendicular to the frame 100. The push rod 310 only needs to move a small distance to make the moving wheel 200 support the frame 100.

[0043] In one embodiment, see Figure 1 , Figure 3 , Figure 5 and Figure 6 The bottom of the frame 100 is provided with an anti-skid sheet 500, and the anti-skid sheet 500 improves the stability of the frame 100 when it is not moving.

[0044] In order to better understand the present invention, the following Figures 1 to 6 The technical solution of the utility model is described in detail: when the frame 100 needs to be moved, the pressure rod 430 is rotated clockwise, and the pressure rod 430 drives the two rotating sleeves 420 to rotate together through the rotating shaft 410. The rotating sleeve 420 rotates and pushes the push rod 310 to approach the moving wheel 200 through the second connecting rod 330. The moving wheel 200 rotates along the connection with the rectangular groove 110 as the center of the circle to lift the frame 100. The pressure rod 430 is rotated counterclockwise, and vice versa;

[0045] Furthermore, the rotation direction of the extension rod 450 is perpendicular to the rotation direction of the pressure rod 430. The pressure rod 430 rotates clockwise and rotates the extension rod 450 to one side, so that one end of the extension rod 450 is embedded in the positioning groove 130, so that the pressure rod 430 can be fixed and reset. When the pressure rod 430 needs to be reset, the extension rod 450 is first rotated to disengage it from the positioning groove 130. The parts of the device are installed in a relatively open rectangular groove 110, which is simple to operate and has a reasonable structure, and the difficulty of maintenance or replacement is greatly reduced.

[0046] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
