Description

Technical Field

[0001] The utility model relates to a crawler type plate inserter, in particular to a support leg for enhancing the stability of the crawler type plate inserter. Background Art

[0002] At present, plastic drainage boards combined with the preloading method are widely used in soft foundation treatment. Crawler-type plate inserters are very popular in drainage board construction because of their simple structure and flexible and convenient site transfer. During construction, the soft ground behind the plate inserter will settle; at the same time, the depth of the plate inserter in this project is large, with the deepest reaching 37 meters, so the height of the plate inserter frame must reach more than 40 meters to meet the construction requirements. Due to the strong winds prevailing in coastal areas, the stability of the plate inserter will be seriously affected. Therefore, there are higher requirements for the anti-tilt stability of the structure of this type of plate inserter, and additional reinforcement is required. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a support leg for enhancing the stability of a crawler-type plate inserter, thereby greatly improving the stability of the crawler-type plate inserter and reducing safety risks.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A support leg for enhancing the stability of a crawler-type plate-scaling machine comprises a base, which is divided into multiple groups and fixed on the outer wall of the crawler. A cantilever bracket is rotatably mounted on the base via a first rotating shaft, and the cantilever bracket is horizontally rotated outward to extend or horizontally rotated inward to approach the outer wall of the crawler. A support leg is rotatably mounted on the other end of the cantilever bracket via a second rotating shaft and is locked by bolts. When the support leg is rotated to a vertical state, the lower end of the support leg is supported on the ground.

[0006] The device is made of stainless steel.

[0007] There are 4 groups of bolts, which are on the same circle and the angles between adjacent bolts are all 90 degrees. The second rotating shaft is located at the center of the circle.

[0008] A bottom plate is installed at the lower end of the supporting leg.

[0009] The utility model provides a support leg for enhancing the stability of a crawler-type plate inserter, which has the following effects:

[0010] 1) By setting multiple sets of outriggers on the left and right outer sides of the crawler type plate inserter, multiple sets of outriggers can be opened in windy weather, when construction is suspended, or when the ground is not flat, to enhance the stability of the crawler type plate inserter.

[0011] 2) Since the first rotating shaft is arranged vertically, the cantilever bracket can rotate horizontally and drive the supporting legs to expand or close to the side wall of the crawler type plate inserter, which will not cause obstacles or impacts on the upper structure of the crawler type plate inserter. By arranging the axial direction of the second rotating shaft horizontally, the supporting legs can rotate around the cantilever bracket and face vertically to the ground, thereby achieving stable support.

[0012] 3) By arranging four groups of bolts on a circle on the periphery of the second rotating shaft (corresponding to the cantilever bracket and the holes on the supporting leg), the four groups of bolts are evenly arranged circumferentially. In this way, no matter whether the supporting leg is rotated to a vertical state or a horizontal state, it can be fixed by four groups of bolts / four groups of holes; at the same time, the positioning can be quickly adjusted to a horizontal state or a vertical state by four groups of bolts / four groups of holes.

[0013] 4) Since the outriggers are not needed under normal construction conditions and are only used in windy weather or when work is stopped, in order to minimize the impact on normal construction, the outriggers are set as a retractable structure that can be retracted close to the outer wall of the crawler track.

[0014] 5) Although the patent "Anti-tilt mechanism for a tracked unmanned vehicle" with application number "202320868852.7" can also provide support and prevent rollover, it cannot be processed directly on site. However, all parts in this application can be processed directly on site, which is low-cost and efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In the figure: base 1, first rotating shaft 2, cantilever bracket 3, supporting leg 4, bottom plate 5, reinforcing rib 6, second rotating shaft 7, bolt 8. DETAILED DESCRIPTION

[0021] like Figure 1-2As shown, a support leg for enhancing the stability of a crawler type plate inserter includes a base 1, which is made of a 2 cm thick Q235 steel plate welded to the outer wall of the crawler. A first rotating shaft 2 is arranged on the base 1, and the first rotating shaft 2 is connected to a cantilever bracket 3. The axial direction of the first rotating shaft 2 is vertical, and the length direction of the cantilever bracket 3 matches the length direction of the crawler and is always in a horizontal plane. When the cantilever bracket 3 is rotated, the cantilever bracket 3 rotates horizontally outward and extends out, or rotates horizontally inward and close to the outer wall of the crawler.

[0022] The cantilever bracket 3 is made of 2 cm thick Q235 steel plate, and reinforcing ribs 6 are arranged on both sides of the cantilever bracket 3 to increase the rigidity of the cantilever bracket 3. The other end of the cantilever bracket 3 is connected to the support leg 4 through a connecting assembly. The connecting assembly includes 4 bolts 8 and a second rotating shaft 7. Among them, the 4 bolts 8 are on the same circle and have an angle of 90 degrees with each other, and the second rotating shaft 7 is located at the center of the circle. In this way, when the 4 bolts 8 are loosened, the cantilever bracket 3 and the support leg 4 can be rotated to achieve verticality or on the same line. By locking the 4 bolts 8, the cantilever bracket 3 and the support leg 4 can be fixed by the bolts 8 regardless of whether the cantilever bracket 3 is vertical or on the same line with the support leg 4. When the support leg 4 is rotated to be vertical to the cantilever bracket 3, it is supported on the ground by the base plate 5.

[0023] like Figure 4 As shown, during daily construction, the device is in a horizontally retracted state. In windy weather, when construction is suspended, or when the ground is not flat, the device can be opened to enhance the stability of the board inserter.

[0024] Working process and principle:

[0025] 1) Rotate the cantilever bracket 3 together with the supporting leg 4 horizontally by 90° so that they are perpendicular to the outer wall of the crawler track.

[0026] 2) Remove the four bolts 8 connecting the support leg 4 and the cantilever bracket 3, loosen them and rotate the support leg 4 90° to make it perpendicular to the ground.

[0027] 3) Re-tighten the four bolts 8 to make it work. When the device is no longer used, it can be put away according to the above process in reverse.
