[0021] Explanation of the reference numerals: 1. first support; 2. second support; 3. lifting ring; 4. sealing set; 5 - upper frame; 6 - CH870 crusher upper arm seal removal device. DETAILED DESCRIPTION

[0022] like Figure 1 and 2 As shown, a CH870 crusher upper boom seal disassembly device comprises: a first support 1, a second support 2 and a lifting ring 3. The device is used for disassembly of the CH870 crusher upper boom seal set.

[0023] The first support 1 is made of Q235 material, with a thickness and width of 20mm and sufficient strength. The upper length of the beam is 480mm, which is just large enough to pass through the inner edge of the upper frame and clamp the sealing set. The angle at the end of the beam is 45-75°, which is convenient for the entry and use of the sealing set.

[0024] The second support 2 is made of Q235 material, with a thickness and width of 20mm. The upper length of the beam is 480mm, with a 20mm wide and 20mm high U-shaped groove in the middle, and the angle of the end of the beam is 45-75°. The first support 1 is clamped in the U-shaped groove of the second support 2 and fixed by welding.

[0025] The first support 1 and the second support 2 are symmetrical in size at 90 degrees, and are connected by four-sided welding.

[0026] The upper end surfaces of the first support 1 and the second support 2 are level to ensure uniformity during the lifting process. There is an M12 bolt hole in the middle of the second support 2. The lifting ring 3 is an M24 lifting ring, and the lifting ring 3 is connected to the second support 2 through the bolt hole.

[0027] The purpose of the U-shaped groove is to facilitate the first support to be directly clamped in the U-shaped groove to ensure the integrity of the first support. The first support with good integrity has higher strength and can withstand greater tension.

[0028] As required, the ends of the first support and the second support are both retractable structures. The ends are fixedly connected by threads and the retractable structure is realized by the cooperation of the threads. The screws / threaded holes at the ends cooperate with the threaded holes / screws on the supports to achieve fine adjustment of the lengths of the two supports, so that the sealing set can be clamped more conveniently through the inner edge of the upper frame, and the stability of the clamping can be improved by the telescopic effect.

[0029] A method for using a CH870 crusher upper boom seal removal device, such as Figure 2 As shown: When disassembling the sealing set, place the device under the sealing set in the upper arm, use a crane to pass the wire rope through the lifting ring, and lift the sealing set.

[0030] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
