Detailed Description

The technical scheme of the utility model is further described below with reference to the accompanying drawings and the specific embodiments.

The utility model relates to a height-adjustable supporting tool, which comprises a supporting leg welding frame 1 and an adjustable support 2, wherein 2 groups of 4 pin shaft holes I7 are formed in the upper part of the supporting leg welding frame 1, a plurality of groups of pin shaft holes II 8 are formed in the adjustable support 2, and the supporting leg welding frame 1 and the adjustable support 2 are connected through 1 group of 2 pin shafts 3 and pass through the corresponding pin shaft holes I7 and the pin shaft holes II 8; the end part of one end of the pin shaft 3 is provided with a handle 9, and the end part of the other end is connected with the cotter pin 4, and is locked by using the cotter pin 4; a backing plate 10 is arranged above the adjustable support 2, and a nylon cushion 5 is arranged above the backing plate 10. The upper part of the support leg welding frame 1 is of a rectangular structure formed by 4 pipe bodies, support legs are arranged at the joints of the 4 pipe bodies, and reinforcing pipes are arranged between the support legs. The upper portion of the supporting leg welding frame 1 is provided with 2 reinforcing pipes, the adjustable support 2 is arranged among the 2 reinforcing pipes, and the distance among the 2 reinforcing pipes is smaller than the length of the backing plate 10. The adjustable support 2 comprises 2 vertical pipes, and 6 groups of 12 pin shaft holes II 8 are formed in the 2 vertical pipes at equal intervals. 2 reinforcing pipes are arranged between the vertical pipes of the adjustable support 2. The nylon cushion 5 is connected with the backing plate 10 through a plurality of countersunk screws 6.

As shown in figure 1, the height of the support leg welding frame 1 is suitable in preparation, and the lowest installation point of the adjustable support seat 2 is ensured to be higher than the ground. The 2 groups of 4 pin shaft holes I7 of the support leg welding frame 1 are subjected to post-welding processing, and the coaxial center lines of the holes are ensured. The adjustable support 2 is provided with 6 groups of 12 pin shaft holes II 8, and the hole distance can meet the lifting height adjustment of movable arms of different models of series of underground shovels. The width of the backing plate 10 is slightly larger than that of the movable arm single side beam, and when the adjustable support 2 falls to the lowest point, two sides can be lapped on the middle two reinforcing pipes of the support leg welding frame 1, so that the support leg welding frame 1 is not separated completely when falling, and the safety performance of the tool is improved. The pin shaft 3 is welded with a handle 9, so that the pin shaft is convenient to hold, and the diameter of the pin shaft 3 is smaller than the aperture of the support leg welding frame 1 and the aperture of the adjustable support 2, so that the pin shaft is convenient to penetrate. The top of adjustable support 2 is installed by nylon pad 5, uses countersunk head screw 6 to fix, can effectively protect the surface quality of movable arm.
