Description

Technical Field

[0001] The utility model relates to the field of drilling rig crawlers, in particular to a highly stable detachable crawler frame. Background Art

[0002] The crawler direct-push soil drilling rig is a mechanical equipment specially used for soil sampling and investigation. It has a wide range of applications, including civil engineering, geological exploration, environmental monitoring and many other fields.

[0003] There is a large downward force when the drill rod is in use, so the crawler frame needs to have a large bearing capacity, and the requirements for the crawler frame are high; the current traditional crawler frame is a welded structure, which is prone to cracks during use, resulting in overall instability; at the same time, when the crawler frame is damaged, it is difficult to replace due to welding, resulting in relatively low maintenance efficiency. Utility Model Content

[0004] The utility model aims to provide a high-stability detachable crawler frame which has high structural strength and is easy to assemble.

[0005] The purpose of the utility model is achieved as follows: a high-stability detachable crawler frame, including a walking frame and a connecting bridge arranged on the walking frame; symmetrical inverted L-shaped concave surfaces are provided on both sides of the connecting bridge, and the inverted L-shaped concave surfaces are composed of horizontal contact surfaces and vertical contact surfaces; extension plates are provided on both sides of the horizontal contact surfaces, and the extension plates are connected to the horizontal surface of the walking frame by bolts; two upper and lower groups of serrated grooves are provided on the vertical contact surface, and L-shaped plates are provided between the two groups of serrated grooves and at the top and bottom of the serrated grooves; two groups of contact serrations are provided on the inner vertical surface of the walking frame, and the contact serrations are slidably matched with the serrated grooves.

[0006] Preferably, the L-shaped plate and the extension plate are both provided with fixing holes, and are fixed to the walking frame by bolts.

[0007] Preferably, the connecting bridge is composed of a plurality of groups of side panels, and a supporting plate is provided inside the connecting bridge.

[0008] Preferably, the walking frame is provided with a through hole for cooperating with a bolt, a fixing block is provided on the inner side of the side plate of the walking frame, a blind hole is provided on the fixing block and is connected with the through hole, and an internal thread is provided in the blind hole.

[0009] Preferably, the interfaces between the interfering serrations and the serration grooves are both right triangles, and the length of the interfering serrations is smaller than the length of the serration grooves.

[0010] Compared with the prior art, the utility model is beneficial in that:

[0011] 1. Bolts are used to connect the bridge and the traveling frame, and welding is avoided. Since welding depends on the workers' operating skills, cracks in the welds should be avoided, which may cause the connection between the bridge and the traveling frame to become loose, resulting in shaking of the main body of the drilling rig;

[0012] 2. Use multiple sets of limit structures, such as L-shaped plates, extension plates connected to the connecting bridge, and sawtooth grooves connected to the interference grooves; avoid unstable overlap between the two sides of the connecting bridge and the walking frame, and ensure the stability of the overall structure;

[0013] 3. After the connecting bridge and the traveling frame are connected by bolts, the whole structure can be disassembled. When the traveling frame or the connecting bridge is damaged, it can be replaced separately, which is more flexible than welding. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0019] It should be noted that in the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the utility model product is usually placed when in use, which are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance. Terms such as "horizontal", "vertical", and "overhanging" do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0020] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] like Figure 1-3 As shown, a high-stability detachable crawler frame comprises a walking frame 1 and a connecting bridge 2 arranged on the walking frame 1; symmetrical inverted L-shaped concave surfaces 3 are provided on both sides of the connecting bridge 2, and the inverted L-shaped concave surfaces 3 are composed of a horizontal resistance surface 301 and a vertical resistance surface 302; extension plates 4 are provided on both sides of the horizontal resistance surface 301, and the extension plates 4 are connected to the horizontal surface of the walking frame 1 by bolts; two groups of upper and lower sawtooth grooves 3021 are provided on the vertical resistance surface 302, and L-shaped plates 5 are provided between the two groups of sawtooth grooves 3021 and at the top and bottom of the sawtooth grooves 3021 to ensure that the L-shaped plates will not contact the resistance sawtooth on the sliding route of the connecting bridge; two groups of resistance sawtooths 6 are provided on the inner vertical surface of the walking frame 1, and the resistance sawtooths 6 are slidably matched with the sawtooth grooves 3021. When matching, the inverted L-shaped concave surfaces on both sides of the connecting bridge are overlapped between the walking frames, and then the connecting bridge is moved forward until it contacts with the resistance sawtooth.

[0022] As shown in the figure, fixing holes are provided on the L-shaped plate 5 and the extension plate 4, and they are fixed to the traveling frame 1 by bolts. The bolt connection facilitates disassembly and assembly and subsequent maintenance, thereby improving efficiency.

[0023] like Figure 1As shown, the connecting bridge 2 is composed of multiple groups of side panels, and a support plate is provided inside the connecting bridge (not shown in the figure, the support plate is horizontal with the walking frame when installed). By setting multiple groups of support plates, the overall structural strength of the connecting bridge can be increased and the bearing capacity can be improved.

[0024] like Figure 3 As shown, a through hole 101 is opened on the walking frame 1 to cooperate with the bolt, and a fixing block 102 is provided on the inner side of the side plate of the walking frame 1. A blind hole 1021 is provided on the fixing block 102 to communicate with the through hole, and an internal thread is provided in the blind hole. Since the thickness of the side plate is relatively small, it is avoided that the bolt is only connected to the side plate after installation, resulting in a small contact area between the bolt and the side plate, further resulting in a decrease in the fixing force of the bolt, and finally causing the loosening of the walking frame and the connecting bridge.

[0025] like Figure 1-2 As shown, the interfaces of the conflicting sawtooth 6 and the sawtooth groove 3021 are both right triangles, the length of the conflicting sawtooth 6 is smaller than the length of the sawtooth groove 3021, the vertical surface of the conflicting sawtooth is integrally connected to the walking frame, and another set of horizontal surfaces conflicts with the sawtooth groove, ensuring that the conflicting sawtooth and the sawtooth groove form the maximum contact area, further ensuring stability; after the sawtooth groove and the conflicting sawtooth are matched, it is ensured that the conflicting sawtooth will not be exposed outside the sawtooth groove, ensuring the overall aesthetics, while also reducing the use of steel.

[0026] The working principle of the utility model is explained as follows: when fitting, the inverted L-shaped concave surfaces on both sides of the connecting bridge are overlapped between the walking frames, and then the connecting bridge is moved forward until it contacts the interfering serrations, and then the extension plate and the L-shaped plate are fixed to the walking frame by bolts, thereby completing the connection between the walking frame and the connecting bridge; the bolt connection method is easy to disassemble and assemble, thereby improving the efficiency of later maintenance.

[0027] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary personnel in the field to the technical solution of the present invention should fall within the protection scope of the present invention, and the technical contents of the present invention for protection have been fully recorded in the claims.
