Description

Technical Field

[0001] The utility model belongs to the technical field of drilling equipment, and specifically relates to a narrow-gauge crawler installation structure and an exploration drill rig. Background Technique

[0002] Crawler drills have strong cross-country and climbing abilities, are not prone to sinking in wet, muddy or soft soil, and can adapt to harsh field environments. They are widely used in fields such as mineral exploration, railways and highways, water conservancy and hydropower, and bridges and tunnels. However, the overall width of existing crawler drills is relatively wide, making it difficult to transport them using containers or to pass through narrow roads, which affects the normal use of crawler drills due to objective conditions.

[0003] After retrieval, it is found that the Chinese utility model patent document (application number 202222316515.5) discloses an adjustable-spacing drill rig crawler, including a crawler main body; there are two groups of the crawler main bodies, and a device main body is arranged between the two groups of the crawler main bodies. The top of the device main body is provided with a device top plate, and an adjustment mechanism is arranged inside the device main body. The adjustment mechanism includes an adjustment chamber, which is opened inside the device main body. A motor is fixedly connected to the position near the rear end of the bottom end of the adjustment chamber. A screw rod is fixedly connected to the rotating shaft part of the motor. Limiting rods are arranged on both horizontal sides of the screw rod. Movable platforms are connected to both ends of the screw rod through threads. A limiting plate is arranged between the two groups of movable platforms. The limiting plate is fixedly connected to the bottom end of the adjustment chamber. Multiple through holes are opened on the surface of the limiting plate. The function of adjustable crawler spacing is realized through the structural design of the adjustment mechanism.

[0004] The above solution sets up a special adjustment mechanism for adjusting the spacing between the crawlers, with a relatively complex structure, a large damage coefficient, and a high maintenance cost. The utility model does not require a complex adjustment mechanism, but only needs to move the crawlers inward by a certain distance to achieve the effect of reducing the overall width of the drill rig. In contrast, the technical solution of the utility model is more convenient and economical, reducing the manufacturing / maintenance cost. Content of the Utility Model

[0037] In order to enable those skilled in the art to better understand the technical solution of the present application, the technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings and embodiments.

[0038] The structures, proportions, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification, and are not used to limit the limiting conditions under which the present utility model can be implemented. Therefore, they do not have technical essence. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects that the present utility model can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in the present utility model. At the same time, the terms such as "left", "right", "first", "second", "inner", "outer", etc. cited in this specification are only for the convenience of clear narration, and are not used to limit the scope that can be implemented. The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope in which the present utility model can be implemented.

[0039] The crawlers of existing exploration drills are located on both sides of the frame, resulting in a relatively large overall width of the machine, and a wider container is required for transportation, which will undoubtedly increase the transportation economic cost; in addition, when short-distance walking is required, if the road surface is relatively narrow, it may also hinder the normal passage of the crawler drill. The crawler is the widest part of the whole drill. In order to reduce the overall width of the machine, it is necessary to try to reduce the distance between the two crawlers on both sides, thereby reducing the overall width of the drill. The purpose of the present utility model is to conceal the crawlers under the frame, thereby shortening the distance between the two crawlers on both sides, facilitating container transportation or short-distance walking.

[0040] Combined with Figures 1 to 12, A narrow-gauge crawler installation structure of the present utility model includes a vehicle frame 1, a crawler transition mounting frame 2, and a crawler 3; the crawler 3 includes a left crawler 31 and a right crawler 32; the crawler transition mounting frame 2 is used to connect the vehicle frame 1 and the crawler 3; the height of the vehicle frame 1 is higher than that of the crawler 3, so that at least a part of the crawler is hidden under the vehicle frame 1 to shorten the distance between the two crawlers. As for the width of the crawler hidden under the vehicle frame, it can be specifically designed according to the working scenario of the crawler drill and the needs of customers.

[0041] Preferably, the height of the vehicle frame 1 is set to be slightly higher than that of the crawler 3, and the vehicle frame 1 is provided with a notch 12 to avoid interference between the vehicle frame 1 and the crawler 3.

[0042] Preferably, a notch 12 is provided on the left side of the vehicle frame 1 to avoid interference between the left side of the vehicle frame 1 and the left crawler 31; the right crawler 32 is arranged closely along the outer edge of the right side of the vehicle frame 1 to avoid interference between the right side of the vehicle frame 1 and the right crawler 32.

[0043] Lifting the vehicle frame so that the lower plane of the vehicle frame is higher than the upper plane of the crawler can completely hide the crawler under the vehicle frame, but this may bring a problem: the overall center of mass of the machine is too high, weakening the walking stability of the entire drill. Adopting the technical solution that the upper plane of the lifted vehicle frame is slightly higher than the upper plane of the crawler can not only not affect the layout of the entire machine above the upper plane of the vehicle frame but also take into account the walking stability of the entire drill; since the upper plane of the vehicle frame is slightly higher than the upper plane of the crawler, the left crawler is very likely to interfere with the vehicle frame, affecting the normal walking of the crawler. By opening a notch on the left side of the vehicle frame, the problem of interference between the vehicle frame and the crawler can be effectively avoided. The so-called notch can be understood as omitting a part of the vehicle frame that may interfere with the crawler to avoid affecting the normal rotation of the crawler. The upper plane of the vehicle frame is slightly higher than the upper plane of the crawler. Here, "slightly higher" can be set in combination with the size of the opened notch. If the opened notch is very large, the height of the upper plane of the vehicle frame higher than the upper plane of the crawler can be smaller; if the opened notch is smaller, the height of the upper plane of the vehicle frame higher than the upper plane of the crawler can be appropriately larger. For those of ordinary skill in the art, after seeing the technical solution of the present utility model, the understanding of the meaning of "slightly higher" is clear and unambiguous.

[0044] Since the tower of the entire drill is on the right side and the overall center of mass of the machine is biased to the right, and the force on the vehicle frame is mainly on the right side, the right crawler adopts the scheme of being as close as possible to the outer side of the vehicle frame instead of being hidden inside the vehicle frame. In this way, there is no need to open a notch on the right side of the vehicle frame, which can effectively maintain the force on the vehicle frame, and the crawler deviates from the overall center of mass of the machine, which is also beneficial to the overall stability of the machine.

[0045] Of course, such a technical solution may make it difficult for the two crawlers to be symmetrically arranged along the central axis of the drill rig, but this does not affect container transportation or short-distance walking. It should be noted that when the crawler drill rig works, it is supported by a special support device, and the asymmetrical two crawlers will not have a negative impact on the work of the crawler drill rig.

[0046] In the prior art, the transition mounting frame between the vehicle frame and the crawler is mostly installed in a grooved manner for positioning, and there is no lateral limit, so the lateral shear force of the mounting bolts cannot be eliminated. The grooved notch generated by the grooved installation of the vehicle frame bottom beam will cause the reinforcement plate of the vehicle frame bottom beam to be discontinuous, greatly weakening the bearing capacity of the bottom beam.

[0047] To improve the problem of discontinuity of the reinforcement plate of the vehicle frame bottom beam caused by the grooved notch generated by the grooved installation, the grooved connection between the vehicle frame and the crawler transition mounting frame is changed to a cylindrical connection, so that the bottom beam reinforcement plate is designed as a whole.

[0048] An integrated bottom beam reinforcement plate 13 is fixedly arranged below the vehicle frame 1, which can effectively improve the bearing capacity of the vehicle frame bottom beam. A plurality of grooves 132 are arranged on the bottom beam reinforcement plate 13, and protrusions 21 corresponding to the grooves 132 are arranged on the crawler transition mounting frame 2. The grooves 132 are cylindrical grooves, and the protrusions 21 are cylindrical protrusions corresponding to the grooves 132.

[0049] The crawler transition mounting frame 2 is a frame structure welded by rectangular steel pipes. One end of it is connected to the vehicle frame, and there are through holes and cylindrical protrusions for connecting with the vehicle frame above. The cylindrical protrusions cooperate with the cylindrical grooves, which can effectively improve the reliability of bolt connection.

[0050] A plurality of first through holes 22 for connecting with the vehicle frame 1 and a plurality of second through holes 23 for connecting with the crawler 3 are arranged on the crawler transition mounting frame 2; a plurality of first threaded holes 133 are arranged on the bottom beam reinforcement plate 13, and the fastener 4 can fixedly connect the vehicle frame 1 and the crawler transition mounting frame 2 through the first through holes 22 and the first threaded holes 133; second threaded holes 322 corresponding to the second through holes 23 are arranged on the crawler 3, and the fastener 4 can fixedly connect the crawler transition mounting frame 2 and the crawler 3. The fastener is mainly composed of a tooth pad 41 and a bolt 42, and is used for connecting between the crawler, the vehicle frame and the crawler transition mounting frame. A driving motor 321 is built into the crawler and is used for the whole machine of the drill rig to walk.

[0051] Align the protrusions on the crawler transition mounting frame with the grooves on the vehicle frame, and then fasten them with fasteners; then align the mounting threaded holes on the crawler with the through holes on the crawler transition mounting frame, and then fasten them with fasteners, and the installation of the crawler installation structure can be completed. The disassembly process is the opposite, which is very simple.

[0052] A plurality of kidney-shaped holes 131 are provided on the bottom beam reinforcing plate 13. On the one hand, it can appropriately reduce the weight of the integrated bottom beam reinforcing plate. On the other hand, welds with the inner side of the bottom plate can be added inside the kidney-shaped holes, reducing the welds on the side of the bottom beam and the bottom beam reinforcing plate (from full weld to intermittent weld), which can effectively reduce the residual stress and welding deformation generated by welding.

[0053] Another aspect of the present utility model also relates to an exploration drill, and the exploration drill adopts the narrow gauge crawler installation structure described above.

[0054] The present utility model and its implementation manners are schematically described above. The description is not restrictive, and only one of the implementation manners of the present utility model is shown in the drawings. The actual structure is not limited thereto. If those of ordinary skill in the art are inspired by it and design a structural manner similar to the technical solution without creative work without departing from the creative purpose of the present utility model, it shall fall within the protection scope of the present utility model.
