Description

Technical Field

[0001] This utility model relates to the field of gantry crane column fixing technology, and in particular to a fixing component for stabilizing gantry crane columns. Background Technology

[0002] A gantry machining center is a machining center in which the Z-axis of the spindle is set perpendicular to the worktable. The overall structure is a large machining center with a portal frame consisting of double columns and a top beam. There is also a crossbeam in the middle of the double columns. It is especially suitable for machining large workpieces and workpieces with complex shapes. Therefore, it is necessary to ensure the stability of the gantry machine's column installation.

[0003] Existing patent (publication number: CN222520546U) discloses "This utility model discloses a double column for a gantry milling machine, relating to the field of gantry milling machine technology. Specifically, it describes a double column for a gantry milling machine, including a gantry column with a mounting groove for mounting bolts at the bottom of its outer side. The gantry column is generally herringbone-shaped, and its inner wall is fixedly connected to ribs that support it. These ribs are in a star-shaped pattern. A support frame is also provided in the middle of the gantry column's interior. The support frame is fixed at the intersection point with the ribs on the inner wall of the gantry column, and a fixed base is fixedly connected to the bottom of the support frame. This double column for a gantry milling machine, by adopting a herringbone shape and supported by the star-shaped ribs on its inner wall, can effectively suppress the machine tool's forward tilt, ensuring processing stability. Furthermore, the internal support frame makes the gantry column more stable."

[0004] In the process of developing this application, the inventors discovered the following problems with the aforementioned comparative patent: When the device is in use, although the driving inclined plate and the limiting column can be moved by the second spring to fix the locking sleeve, the user still needs to pull the two driving inclined plates at the same time before fixing the locking sleeve, which is not conducive to improving work efficiency.

[0005] Therefore, this application provides a fastener for stabilizing the column of a gantry crane to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fixing component for stabilizing the column of a gantry crane. When using this device, the fixing frame and the main body can be manufactured separately and then assembled, which simplifies the production of the device and facilitates the maintenance of the fixing frame in the later stages.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fixing component for stabilizing the column of a gantry crane, comprising a fixing frame, a first main body and multiple fixing bolts, wherein a bidirectional screw is rotatably arranged inside the first main body, and two connecting blocks are threaded around the bidirectional screw, and two fixing rods are fixedly arranged on the side of the two connecting blocks that are far apart from each other.

[0008] The fixing frame includes a second main body, and fixing plates are fixedly installed on both sides of the second main body. Both fixing plates have multiple second through holes. A first fixing groove is opened at the upper end of the first main body. The second main body is slidably engaged and installed inside the first fixing groove through the two fixing plates.

[0009] Furthermore, a handle is fixedly provided at one end of the bidirectional lead screw.

[0010] Furthermore, both connecting blocks are slidably disposed inside the lower end of the first main body.

[0011] Furthermore, all of the aforementioned fixing bolts pass through the first main body and the two fixing plates, and one end of each of the aforementioned fixing bolts is provided with a nut.

[0012] Furthermore, a second fixing groove is provided on both sides of the lower end of the first main body, and a locking sleeve is slidably engaged inside each of the four second fixing grooves.

[0013] Furthermore, all four fixing rods are slidably disposed inside the lower end of the first main body, and the four fixing rods are respectively slidably disposed inside the four locking sleeves.

[0014] Furthermore, springs are connected between each of the four locking sleeves and the main body.

[0015] Furthermore, a through hole is provided at both ends of the lower side of the main body.

[0016] This utility model has the following beneficial effects:

[0017] 1. The present invention proposes a fixing component for stabilizing the column of a gantry crane. During production, the fixing frame and the first main body can be produced separately. Then, the fixing frame is inserted into the first fixing groove. Then, multiple fixing bolts are inserted from one side of the first main body, passing through two fixing plates and being pushed out from the other side of the first main body. Then, nuts are installed on one end of the fixing bolts, which helps to fix the fixing frame and the first main body together and makes the production of the device more convenient.

[0018] 2. The present invention proposes a fixing component for stabilizing the column of a gantry crane. When in use, rotating the handle drives the bidirectional lead screw to rotate, which in turn drives the two connecting blocks to move closer to each other. The two connecting blocks then drive the four fixing rods to move closer to each other in pairs. This makes it easier and faster to release the fixing rods from the locking sleeve, eliminating the need for the user to constantly fix the fixing rods with one hand, thus improving work efficiency.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4This utility model provides an embodiment of a fixing component for stabilizing a gantry crane column, comprising a fixing frame 1, a primary body 2, and multiple fixing bolts 3. A bidirectional lead screw 13 is rotatably mounted inside the primary body 2. Two connecting blocks 12 are threaded around the bidirectional lead screw 13. Two fixing rods 8 are fixedly mounted on the opposite sides of the two connecting blocks 12. A fixing groove 5 is formed at the upper end of the primary body 2. A handle 4 is fixedly mounted at one end of the bidirectional lead screw 13. The two connecting blocks 12 are slidably mounted inside the lower end of the primary body 2. Multiple... All fixing bolts 3 pass through the first main body 2 and the two fixing plates 101. One end of each fixing bolt 3 is provided with a nut 11. The lower end of the first main body 2 is provided with two fixing grooves 6 on both sides. Locking sleeves 9 are slidably engaged inside the four fixing grooves 6. Four fixing rods 8 are slidably disposed inside the lower end of the first main body 2. The four fixing rods 8 are respectively slidably disposed inside the four locking sleeves 9. Springs 7 are connected between the four locking sleeves 9 and the first main body 2. A first through hole 10 is provided through both ends of the lower side of the first main body 2.

[0028] Specifically, rotating the handle 4 drives the bidirectional lead screw 13 to rotate, which in turn drives the two connecting blocks 12 to move closer together. The two connecting blocks 12 then drive the four fixing rods 8 to move closer together, thereby disengaging the fixing rods 8 from the locking sleeve 9. This facilitates the installation of the locking sleeve 9 during the production of the device. The locking sleeve 9 helps to limit the bolts used to install the device, thus improving the stability of the device. The spring 7 pushes the locking sleeve 9 downward, further enhancing its stability. The fixing bracket 1 improves the stability of the first body 2. The first fixing slot 5 facilitates the user's installation of the fixing bracket 1. The fixing bolt 3 is inserted from one side of the first body 2, then passes through the fixing bracket 1 and the first body 2. The nut 11 is then fixed to one end of the fixing bolt 3, which helps to fix the fixing bracket 1 and the first body 2 together, improving the stability of the first body 2. Furthermore, the fixing bracket 1 and the first body 2 can be produced separately, improving production convenience.

[0029] Reference Figure 5 The fixing frame 1 includes a second main body 103. Fixing plates 101 are fixedly installed on both sides of the second main body 103. Both fixing plates 101 have multiple second through holes 102. The second main body 103 is slidably engaged with the two fixing plates 101 and installed inside the first fixing groove 5.

[0030] Specifically, the two fixing plates 101 help to install the fixing bracket 1 more stably inside the first body 2, and allow the second through hole 102 to be directly aligned with the fixing bolt 3, thereby improving the installation efficiency of the fixing bracket 1; the second body 103 can improve the stability of the first body 2.

[0031] Working principle: When in use, rotating the handle 4 drives the bidirectional lead screw 13 to rotate. The bidirectional lead screw 13 drives the two connecting blocks 12 to move closer to each other, which in turn drives the four fixing rods 8 to move closer to each other in pairs, causing them to disengage from the locking sleeve 9. This makes it easier to install the locking sleeve 9 during production, improving work efficiency. In addition, rotating the nut 11 disengages it from the fixing bolt 3, and then the fixing frame 1 is pulled out from the first fixing groove 5. This allows the fixing frame 1 and the first main body 2 to be produced separately and then assembled together, simplifying production and improving production efficiency. Furthermore, the fixing frame 1 can be disassembled for maintenance later, improving the practicality of the device.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
