[0003] The purpose of this invention is to provide an improved counterweight structure for hydraulic machine tools, which makes it easier to move the worktable out of the main hydraulic machine tool.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an improved counterweight structure for a hydraulic machine tool, comprising a cable, characterized in that a ground hole is arranged at the hydraulic machine tool, a counterweight wheel is arranged in the ground hole, a winding part is provided at the entrance of the ground hole, the winding part has a first winding part on one side and a second winding part on the other side, a cable groove is provided on the left side of the first winding part, and the ends of the cable are respectively connected to the movable worktable and the counterweight wheel.

[0005] Further: The borehole has a rectangular cross-section.

[0006] Further: The winding section has a winding frame with winding frame holes. A wire box is provided on the winding frame and above the winding frame holes. A first winding section is provided on one side of the wire box, which includes multiple first winding rollers. A second winding section is provided on the other side, which includes multiple second winding rollers.

[0007] Compared with the prior art, the present invention has the following advantages: the present invention uses counterweight wheels to make it easier to move the worktable out of the hydraulic machine tool host. Attached Figure Description

[0017] Example 1

[0018] See Figures 1 to 8 An improved counterweight structure for a hydraulic machine tool includes a cable 11, a ground hole 12 arranged at the hydraulic machine tool 100, a counterweight wheel 13 arranged inside the ground hole 12, a winding section provided at the entrance of the ground hole 12, the winding section having a first winding section on one side and a second winding section on the other side, a cable groove 14 provided on the left side of the first winding section, and the ends of the cable 11 being connected to a movable worktable 101 and a counterweight wheel 13 respectively (the cable passes around the winding section, enters the ground hole and connects with the counterweight wheel).

[0019] In the embodiment, the cross-section of the borehole 12 is rectangular.

[0020] In this embodiment, the winding section has a winding frame 161, a winding frame hole 161a is provided on the winding frame 161, a wire box 162 is provided on the winding frame 161 and above the winding frame hole 161a, a first winding section is provided on one side of the wire box 162, the first winding section includes a plurality of first winding rollers 163, and a second winding section is provided on the other side, the second winding section includes a plurality of second winding rollers 164.

[0021] When the movable worktable 101 moves away from (removes out of) the hydraulic machine tool main unit 100 ( Figure 1 (The right-hand movable worktable is in its current state), with the counterweight wheel at the lowest point B in the ground hole. Under power, the movable worktable moves into the hydraulic machine tool host. During this process, the cable is placed in the cable tray (this does not affect the operation of the movable worktable).

[0022] After the movable worktable 101 enters (moves into) the hydraulic machine tool main unit 100, Figure 1 (The left-hand movable worktable is in its current state), with the counterweight roller at the highest point A in the borehole. After the hydraulic operation is completed, the movable worktable moves out of the hydraulic machine tool host under the action of power. Due to the counterweight roller, the movement is relatively easy. This continues until the movable worktable is moved to a position far away from the hydraulic machine tool host.

[0023] The hydraulic machine tool part can refer to existing technology and will not be described in detail.

[0024] Example 2

[0025] The difference between this embodiment and Embodiment 1 is that a guide wheel assembly is provided at the cable insertion point of the movable worktable 101, including an upper guide wheel 101a on the upper side and a lower guide wheel 101b on the lower side. This design facilitates the use of cables.

[0026] Example 3

[0027] The difference between this embodiment and embodiments 1 and 2 is that four lower winding rollers 15 are arranged circumferentially below the winding frame hole. This design facilitates the use of cables.

[0028] Example 4

[0029] The solution is the same as in Implementation Examples 1, 2, or 3; the differences are as follows: Figure 9 The figure shows a top view. To facilitate the use of the borehole, multiple inverted U-shaped clamps 17 are installed at the entrance of the borehole 12. The figure shows 5 clamps, but the number can be increased or decreased as needed.

[0030] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above-described embodiments. All technical solutions that fall within the principles of this utility model are within its protection scope. For those skilled in the art, any improvements made without departing from the principles of this utility model should also be considered within its protection scope.
