Abstract
Description
Technical Field
[0001] This utility model relates to a drilling rig, and more particularly to a power head slide that is easy to maintain. Background Technology
[0002] The power head of the drilling rig is mounted on the base, which is slidably mounted on the slide rail. As the base slides on the slide rail, friction can easily cause wear on the inner wall of the base. Over time, if the inner wall of the base is severely worn, the base needs to be replaced, resulting in high operating costs. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a power head slide that has a long service life, low operating cost, and is easy to maintain.
[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a power head slide that is easy to maintain, including a seat body that is slidably fitted on a slide rail, the seat body and the slide rail being clearance-fitted, and a plurality of sliding support devices installed between the seat body and the slide rail to prevent the seat body from contacting the slide rail. The sliding support device includes a mounting hole provided on the seat body, a pressure cap installed on the outside of the mounting hole, a support pad installed in the mounting hole between the pressure cap and the slide rail, one side of the support pad extending inward and pressing against the slide rail, a rigid pad plate also installed in the mounting hole on the outside of the support pad, and a clamping adjustment device installed on the pressure cap to ensure that the support pad is always in contact with the slide rail.
[0005] As a preferred technical solution, the slide rail is a square slide rail, the base is a square sliding sleeve, and two sets of the sliding support devices are provided on each side of the slide rail and the base.
[0006] As a preferred technical solution, the support pad is a nylon pad.
[0007] As a preferred technical solution, the clamping adjustment device includes two screw holes provided on the pressure cover, and a clamping adjustment bolt is installed in each screw hole.
[0008] As a preferred technical solution, the clamping adjustment device includes two screw holes provided on the pressure cover, and a clamping adjustment screw is installed in each screw hole. The end of the clamping adjustment screw is provided with an internal hexagonal hole.
[0009] Due to the adoption of the above technical solution, the power head slide, which is easy to maintain, includes a seat body that is slidably fitted onto a slide rail. The seat body and the slide rail are clearance-fitted. Several sliding support devices are installed between the seat body and the slide rail to prevent the seat body from contacting the slide rail. Each sliding support device includes a mounting hole on the seat body. A pressure cap is installed on the outside of the mounting hole. A support pad is installed in the mounting hole between the pressure cap and the slide rail. One side of the support pad extends inward and presses against the slide rail. A rigid pad is also installed in the mounting hole on the outside of the support pad. A clamping adjustment device is installed on the pressure cap to ensure that the support pad is always in contact with the slide rail. During the sliding process of the seat body on the slide rail, the seat body does not directly contact the slide rail, but contacts the slide rail through the support pad. Therefore, the seat body will not be damaged by friction during the sliding process, which can extend the service life of the equipment and reduce the operating cost. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.
[0016] like Figures 1 to 3As shown, the easy-to-maintain power head slide includes a seat body 2 that is slidably fitted onto a slide rail 1. The seat body 2 and the slide rail 1 are clearance-fitted. Several sliding support devices 3 are installed between the seat body 2 and the slide rail 1 to prevent the seat body 2 from contacting the slide rail 1. Each sliding support device 3 includes a mounting hole on the seat body 2. A pressure cover 31 is installed on the outside of the mounting hole and is bolted to the seat body 2. A support pad 32 is installed in the mounting hole between the pressure cover 31 and the slide rail 1. One side of the support pad 32 extends inward and presses against the slide rail 1. A rigid pad 4 is also installed in the mounting hole on the outside of the support pad 32. A clamping adjustment device is installed on the pressure cover 31 to ensure that the support pad 32 is always in contact with the slide rail 1.
[0017] The slide rail 1 is a square slide rail 1, the base 2 is a square sliding sleeve, and two sets of the sliding support devices 3 are provided on each side of the slide rail 1 and the base 2.
[0018] The support pad 32 is a nylon pad. Using a nylon pad ensures the support strength between the seat 2 and the slide rail 1, while also reducing the friction on the slide rail 1 and minimizing wear and tear during sliding. Furthermore, the use of nylon pads further reduces operating costs due to their low cost.
[0019] The clamping adjustment device includes two screw holes on the pressure cover 31, and a clamping adjustment bolt is installed in each screw hole. Alternatively, the clamping adjustment device includes two screw holes on the pressure cover 31, and a clamping adjustment screw 33 is installed in each screw hole. The end of the clamping adjustment screw 33 is provided with an internal hexagonal socket, and the clamping adjustment screw 33 can be adjusted by inserting an internal hexagonal rod into the internal hexagonal socket.
[0020] During use, when the support pad 32 becomes thinner due to friction, the support pad 32 can be pushed inward by rotating the clamping adjustment bolt or clamping adjustment screw 33 to ensure that the support pad 32 is in contact with the slide rail 1. When the thickness of the support pad 32 becomes thinner than the adjustment range of the clamping adjustment bolt or clamping adjustment screw 33, the pressure cover 31 can be removed and a new support pad 32 can be installed.
[0021] The slide rail 1 can also be a circular slide rail 1. When a circular slide rail 1 is used, the mechanism of the support pad 32 and the pressure cover 31 also needs to adopt an arc-shaped structure that matches the circular slide rail 1.
[0022] Taking a core drilling rig as an example, this easy-to-maintain power head slide is explained. The core drilling rig includes a base, with a rotating shaft rotatably mounted at one end of the base. A slide rail 1 is vertically fixed on the rotating shaft. The power head slide is fitted onto the slide rail 1 and moves along the slide rail 1. The core drilling rig's head assembly is fixedly mounted on the slide. When the core drilling rig is working, the drilling angle needs to be adjusted in advance. During the adjustment process, in order to adapt to the angle adjustment, the power head slide needs to move up or down on the slide rail 1. A sliding support device 3 is set inside the slide. The core component of the sliding support device 3 is a nylon pad, which is not only wear-resistant but also reduces sliding noise and makes the sliding smoother and more stable.
[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
