Description

Technical Field

[0001] This utility model belongs to the field of underground mine surveying technology, and relates to an extension bar support device for an underground mine scanner. Background Technology

[0002] During mining operations, it is often necessary to perform 3D scanning measurements on areas such as goafs and tunnels in underground mines. Due to the confined spaces and complex structures of these areas, traditional single-point measurement methods are insufficient. In such cases, using an underground mine scanner in conjunction with an extension bar allows for comprehensive and accurate measurements of these complex areas.

[0003] Traditional methods of moving scanners require significant manpower and time to transport and adjust their position. Existing scanner support devices can greatly improve scanner movement speed, allowing operators to quickly move the scanner to the desired location, thus saving considerable time and labor costs. However, due to the complex, confined, and variable environment of underground mines (uneven ground, slopes, pits, or slippery surfaces), existing scanner support devices often fail to meet practical needs, especially when extending the scanning range, exhibiting problems such as insufficient stability and difficulty in adjusting the scanner's height and angle.

[0004] Therefore, it is necessary to design an extension bar support device that enables stable support and flexible adjustment of the scanner in underground mining environments. Utility Model Content

They are used only for the convenience of describing this utility model and do not require that this utility model be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. The terms "connected," "linked," and "set up" used in this utility model should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a direct connection or an indirect connection through intermediate components; a wired connection, a radio connection, or a wireless communication signal connection. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0039] Please see Figure 1-6 This utility model provides the following technical solution: an extension bar support device for an underground mining scanner. The extension bar support device includes: a bucket 1, a support mechanism 2, and a locking mechanism. Specifically, rollers 4 are mounted on the bottom of the bucket 1 via a main shaft. The position of the bucket 1 can be changed via the rollers 4; typically, four rollers 4 are sufficient for use. The support mechanism 2 is located inside the bucket 1 and supports the extension bar 7 connected to the underground mining scanner 8, allowing the scanner 8 to be tilted upwards. Simultaneously, the support mechanism 2 and the extension bar 7 are movably connected. When adjusting the angle between the extension bar 7 and the horizontal plane (e.g., 10-60° is sufficient for practical use), the contact position (also called the connection point) between the support mechanism 2 and the extension bar 7 changes with the support mechanism 2 as a reference, and the support mechanism 2 always provides support. The locking mechanism is located inside the bucket 1 and is used to lock the lower end of the extension bar 7, which is spaced apart from the aforementioned connection point. Before use, this device should be moved to the work site. In use, the lower part of the extension bar 7 with the underground mining scanner 8 is inserted into the truck bed 1 and connected to the support mechanism 2. At the same time, the lower end of the extension bar 7 is locked by the locking mechanism to prevent the extension bar 7 from moving left or right. Figure 4 Using the image shown as a reference (left side of truck bed 1 is left direction, right side of truck bed 1 is right direction), manually adjust the angle between the extension bar 7 and the horizontal plane to change the position of the extension bar 7 inside the truck bed 1. Stop adjusting when the angle between the extension bar 7 and the horizontal plane meets the actual needs of the scanner 8 at the work site. At this point, the positional relationship between the extension bar 7 and the truck bed 1 is determined. The locking mechanism prevents the scanner 8 from moving or shaking during scanning, ensuring stable support for the scanner 8 in the underground mining environment and improving scanning accuracy and efficiency.

[0040] As an embodiment of the specific structure of the aforementioned support mechanism 2, in this embodiment, the support mechanism 2 includes: a base 21 and a clamping component 22. Specifically, refer to... Figure 5 As shown, the base 21 is located on the inner side of the bottom of the truck bed 1. The clamping component 22 is located on the base 21 and is connected to the base 21, such as by bolts. The clamping component 22 has a mounting hole for supporting the extension bar 7. Preferably, the bottom plate of the truck bed 1 has a downwardly recessed slide rail 10 along the running direction of the truck bed 1. The base 21 can be located above the slide rail 10 or inside the slide rail 10. During installation, the lower end of the extension bar 7 is inserted into the mounting hole on the clamping component 22 and abuts against the slide rail 10. In this way, the clamping component 22 can provide support for the extension bar 7. When adjusting the angle, the extension bar 7 is moved forward or backward along the slide rail 7, and the base 21 moves in the same direction as the extension bar 7. By manually changing the position of the extension bar 7 in the slide rail 10, the angle between the extension bar 7 and the horizontal plane can be adjusted.

[0041] As an embodiment of the specific structure of the above-mentioned locking mechanism, in this embodiment, the locking mechanism includes: a pressing insert 9. Specifically, when the base 21 is located above the slide rail 10, the pressing insert 9 is disposed on the slide rail 10 (side wall) on both sides of the extension bar 7 (e.g., Figure 6 (As shown); or when the base 21 is located within the slide rail 10, one embodiment is that the clamping insert 9 is disposed on the slide rail 10 (side wall) below the base 21, and the clamping insert 9 is located on both sides of the extension bar 7. Another embodiment is that clamping inserts 9 are disposed on both the extension bar 7 and the slide rail 10 (side wall) on both sides of the base 21. It can also be understood that two layers of clamping inserts 9 are disposed on the slide rail 10 (side wall), so that the width of the movement track of the base 21 is greater than the width of the movement track of the extension bar 7. One side of the clamping insert 9 is a plane, and the other side (also called the working surface) is provided with a toothed structure for applying clamping force to the target object (such as the extension bar 7). Based on the plane of the clamping insert 9, preferably, the working surface of the clamping insert 9 is provided with a toothed structure with increasing height. That is, the abutting force exerted by the tip of the small tooth on each clamping insert 9 on the extension bar 7 (and base 21) gradually increases along the length of the clamping insert 9. The clamping inserts 9 are used in pairs, and the increasing toothed structures on the working surfaces of the clamping inserts 9 that are positioned opposite each other abut against the side wall of the extension bar 7 (and base 21) to clamp and fix the extension bar 7 (and base 21). This can prevent the extension bar 7 (and base 21) from wobbling left and right when adjusting the angle or during the operation of the scanner 8, thus improving the stability of the device. It should be noted that the number of clamping inserts 9 can be flexibly set according to the length of the slide 10.

[0042] To further improve the stability of the support device, this extension bar support device also includes a top cover 3. Specifically, the top cover 3 is located on the truck bed 1, and a through hole 31 is provided on the top cover 3. In use, the extension bar 7 is inserted into the truck bed 1 through the through hole 31 on the top cover 3 and connected to the support mechanism 2, thus providing support for the upper part of the extension bar 7. It is understood that during the adjustment of the angle, the contact position between the extension bar 7 and the top cover 3 will change with the top cover 3 as a reference. Preferably, the projection of the through hole 31 on the horizontal plane is on the same straight line as the support mechanism 2. Figure 6 As shown, the through hole 31 is located on the front side of the clamping component 22.

[0043] To facilitate the adjustment of the height of the scanner 8, the extension bar 7 is composed of multiple sections of rods connected by threads. Once the angle of the scanner 8 is determined, if the height of the scanner 8 is insufficient or excessive, appropriate sections of rods can be added or removed as needed, thus achieving height adjustment of the scanner 8.

[0044] The front end of the truck bed 1 (with Figure 2 Based on the image shown, a triangular plate is installed on the left side of the truck bed 1 (the forward direction, i.e., the direction of travel of the truck bed 1). A bolt 6 is installed on the triangular plate for connecting traction equipment, such as a car connected by a rope, to transport the device to the underground mine. Preferably, to facilitate pushing the device, a pusher 5 is provided on the truck bed 1. The pusher 5 can be located at the front end of the truck bed 1 or on the triangular plate; this embodiment is not limited to either.

[0045] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
