Description

Technical Field

[0001] This application relates to the field of auxiliary installation equipment technology for mining machinery, and in particular to a cutterhead fixing fixture. Background Technology

[0002] In mining operations, the cutterhead, as a core component of drilling operations, is mainly composed of a center rod and a cutter assembly. Because both the center rod and the cutter assembly are irregular, heavy parts, and the cutter assembly is mounted at an angle on the center rod, they need to be aligned in a certain direction or angle for convenient operation during assembly. This irregular shape leads to low assembly efficiency. Utility Model Content

[0003] To address the aforementioned technical problems, this application proposes a cutter head fixing fixture that assists in fixing the position of the center rod to facilitate the installation of the hob, thereby improving installation efficiency and quality.

[0005] The tool holder according to the embodiments of this application has at least the following beneficial effects: By installing the center rod onto the mounting rod, and then rotating the mounting rod around the hinge point with the base plate, the center rod rotates synchronously and partially rests on the pad. The position of the pad ensures that when the center rod abuts against the pad, the axis of the mounting hole on the center rod remains vertical, thus facilitating the installation of the cutter and improving installation efficiency and quality. Multiple cutters are installed on the center rod, so multiple pads are correspondingly installed on the base plate to ensure that each cutter can be quickly installed.

[0006] In some embodiments of this application, the pad is slidably mounted on the base plate and can be fixed relative to the base plate.

[0007] In some embodiments of this application, the pad is mounted on the base plate in a height-adjustable manner.

[0008] In some embodiments of this application, a limiting structure is provided at the top of the pad, and the limiting structure assists in fixing the central rod.

[0009] In some embodiments of this application, the limiting structure is a limiting groove, which is disposed at the top of the pad.

[0010] In some embodiments of this application, a buffer is installed in the limiting groove.

[0011] In some embodiments of this application, the first limiting ring is fixedly disposed in the middle of the mounting rod, and the second limiting ring is detachably installed in the end of the mounting rod.

[0012] In some embodiments of this application, the end of the mounting rod is provided with a threaded section, and a locking nut is installed on the threaded section; the second limiting ring is sleeved on the threaded section and abuts against the locking nut.

[0013] In some embodiments of this application, a connecting structure is installed at the end of the mounting rod.

[0014] In some embodiments of this application, the mounting rod is ball-jointed with the hinge seat or connected via a pin.

[0015] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0018] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0019] In the description of this application, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

The use of "first" and "second" is for the purpose of distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or the order in which the technical features are indicated.

[0021] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0022] Reference Figures 1 to 2 This application discloses a cutter head fixing fixture, including a base plate, a mounting rod 200, and a pad 300. The base plate is provided with a hinge seat 110, and the mounting rod 200 is hinged to the hinge seat 110. The mounting rod 200 includes a first limiting ring 210 and a second limiting ring 220. A center rod is sleeved on the mounting rod 200 and positioned between the first limiting ring 210 and the second limiting ring 220. The pad 300 is installed on the base plate to support the center rod. The mounting rod 200 rotates around the hinge point with the base plate, causing the center rod to rotate synchronously to a position abutting against the pad 300, so that the axis of the mounting hole remains in the center. Figure 2 The vertical direction shown facilitates the installation of the hob.

[0023] Since the cutter head usually has multiple cutters, that is, multiple cutters are usually installed on the center rod, multiple spacers 300 are provided. Multiple spacers 300 are spaced apart around the outer periphery of the hinge seat 110. The number of spacers 300 is less than or equal to the number of cutters to ensure that each cutter can be installed vertically, thereby improving the installation efficiency and installation quality of the cutters.

[0024] In some embodiments of this application, to avoid an excessive number of pads 300 and to increase the applicability of the fixing fixture in this embodiment, the pads 300 can be configured to slide on the base plate. (Refer to...) Figure 1 As shown, the base plate is provided with a slide rail 120, and the pad 300 is slidably mounted on the slide rail 120. However, it can also be locked with bolts or other fasteners to fix the relative position of the pad 300 and the base plate. By setting the pad 300 to be slidably mounted on the base plate, the number of pads 300 installed on the base plate can be reduced, and the fixing fixture of this embodiment can be used for various sizes and models of cutter heads.

[0025] It is conceivable that if the fixture in this embodiment is only applicable to a specific cutter head, the pad 300 and the base plate can be connected by welding or by fasteners such as bolts to reduce the manufacturing cost of the fixture.

[0026] In some embodiments of this application, the applicability of the fixing fixture in this embodiment can also be improved by setting the pad 300 to be adjustablely mounted on the base plate. For example, an electric lifting mechanism is installed at the bottom of the pad 300, and the electric lifting mechanism drives the pad 300 to rise and fall vertically, so that the fixing fixture can be applied to more types and sizes of cutter heads, and the hobs of different sizes and types of cutter heads can be installed vertically during installation.

[0027] In some embodiments of this application, a limiting structure is provided at the top of the pad 300, which assists in fixing the central rod. Specifically, refer to... Figure 1 , Figure 2 As shown, the pad 300 supports one side of the bottom end of the center rod. When installing the cutter, it is often necessary to tap the cutter to ensure it is in place. Therefore, during the installation of the cutter, the position where the center rod and the pad 300 meet will be subjected to a large pressure, which may cause damage or deformation to the center rod. The top of the pad 300 is equipped with a limiting structure, which can increase the contact area between the center rod and the pad 300, thereby reducing the risk of damage or deformation to the center rod.

[0028] In some specific embodiments of this application, the limiting structure can adopt various technical solutions, such as... Figure 1 , Figure 2 The limiting structure shown is set as a limiting groove 310. Alternatively, the limiting structure can be set as an upper surface protruding from the top of the pad 300. In this embodiment, no limitation is made.

[0029] When the limiting structure is set as the limiting groove 310, it is preferable to install a buffer in the limiting groove 310 to further reduce damage to the center rod. The buffer can be made of materials such as rubber and foam. The specific shape and size of the buffer can be set according to actual needs and are not limited in this embodiment.

[0030] In some embodiments of this application, the mounting rod 200 is hinged to the hinge seat 110 by a ball joint or by a pin connection. Figure 1As shown, the mounting rod 200 and hinge seat 110 are connected by a pin. This pin connection means the mounting rod 200 can only rotate within a single plane, thus the pad 300 can only be arranged in a straight line. However, this method results in lower tooling manufacturing costs. Connecting the mounting rod 200 and hinge seat 110 via a ball joint increases the rotation possibilities of the mounting rod 200 and allows for more flexible placement of the pad 300. In specific products, the connection method between the mounting rod 200 and hinge seat 110 can be selected according to actual needs; for example, a pin connection, a ball joint, or a combination of both can be used.

[0031] In some embodiments of this application, reference is made to Figure 1 , Figure 2 As shown, the first limiting ring 210 is fixedly disposed in the middle of the mounting rod 200, and the second limiting ring 220 is detachably installed at the end of the mounting rod 200. The outer diameter of the first limiting ring 210 is smaller than the outer diameter of the second limiting ring 220. The first limiting ring 210 and the mounting rod 200 are fixedly connected by welding, integral molding or other methods. The second limiting ring 220 and the mounting rod 200 are detachably connected, which facilitates the quick assembly and disassembly of the center rod and improves the convenience of using the tooling in this embodiment.

[0032] In some embodiments of this application, reference is made to Figure 1 As shown, the end of the mounting rod 200 is provided with a threaded section, and a locking nut 230 is installed on the threaded section; the second limiting ring 220 is sleeved on the threaded section and abuts against the locking nut 230. Specifically, when installing the center rod, first remove the second limiting ring 220, then sleeve the center rod on the mounting rod 200 until the first limiting ring 210 abuts against the lower end of the center rod; then install the second limiting ring 220, which is attached to the upper end of the center rod, and then the locking nut 230 tightens the second limiting ring 220 against the center rod, thereby ensuring the stability of the center rod.

[0033] In some embodiments of this application, a connecting structure 240 is mounted on the end of the mounting rod 200. Specifically, Figure 1 , Figure 2 The connecting structure 240 shown is an eye bolt. Because the center rod is large in size and weight, the connecting structure 240 is provided to facilitate the connection of lifting equipment and to assist in the installation of the hoist on the center rod. In some specific embodiments, the connecting structure 240 is not limited to eye bolts; different structures can be used depending on the lifting equipment. This embodiment does not impose such limitations.

[0034] The cutter head fixing fixture of this application embodiment is achieved by installing a central rod on a mounting rod 200, and then rotating the mounting rod 200 around the hinge point with the base plate, causing the central rod to rotate synchronously and partially fall on the pad 300. The position of the pad 300 ensures that when the central rod abuts against the pad 300, the axis of the mounting hole on the central rod remains in the vertical direction, thereby facilitating the installation of the hobbing cutter and improving the installation efficiency and quality. Since multiple hobbing cutters are installed on the central rod, multiple pads 300 are correspondingly installed on the base plate to ensure that each hobbing cutter can be quickly installed.
