[0024] In order to more clearly describe the specific structural composition of the gyratory crusher fixed cone liner installation tool, combined with the attached Figure 1-4 Describe this embodiment: like Figure 1 and Figure 2 As shown, a gyratory crusher fixed cone lining installation tool comprises a ring-grid steel frame 5, which can be lowered into the inner cavity of the conical shell 2 of the gyratory crusher 1 where the lining is to be installed; the top of the ring-grid steel frame 5 is provided with a hoisting component 6 for connecting a hoisting device, and the bottom of the inner cavity of the ring-grid steel frame 5 is provided with a mounting platform 7; On the outside of the ring-grid steel frame 5, there are multiple installation units distributed along the circumference of the ring-grid steel frame 5, and the number of installation units is equal to the number of linings of this layer; each installation unit includes a mounting part 8 that can be snap-fitted with the lining lifting ear 4 and hang the corresponding lining 3 on the outside of the ring-grid steel frame 5, and also includes a positioning part 9 that corresponds to the mounting part 8 and can press the lining 3 against the mounting surface of the inner wall of the conical shell 2.

[0025] When in use, firstly, a plurality of lining plates 3 of the whole circumference of the layer are sequentially hung on the mounting parts 8 of the ring grid steel frame 5 by using an overhead crane, and the number of layers of the mounting parts 8 is determined according to the number of layers (the number of layers in the axial direction) of the lining plates 3 to be installed in the conical shell 2. Figure 1 Only a single-layer mounting part is shown in the figure), after all the lining boards 3 are hung on the mounting parts 8, the entire ring grid steel frame 5 together with the multi-layer lining boards 3 are hoisted into the interior of the conical shell 2 as a whole, and after the clamping connection between the lining boards 3 and the mounting parts 8 is released, the lining boards 3 are pushed up to their outer surfaces through the corresponding positioning parts 9 in sequence so that they can smoothly fit with the inner mounting surface of the conical shell 2, and the installation of the entire layer of lining boards is completed. The lining boards of other layers can be installed in the same way.

[0026] In the above embodiment, a support member capable of supporting the top of the conical shell 2 and suspending the ring-grid steel frame 5 in the conical shell 2 is fixed on the top of the ring-grid steel frame 5. After each layer of lining board is hoisted in, the support member will use the conical shell as support to stably suspend the ring-grid steel frame 5 in the conical shell 2, which is safe and stable, and the next step can be carried out without fixing the installation tool again.

[0027] Specifically, the support member includes a support block 10 fixed on the top of the ring-grid steel frame 5 and extending to the outside of the ring-grid steel frame 5 , and the support block 10 is connected to the side surface of the ring-grid steel frame 5 through a reinforcing rib 11 .

[0028] In the above embodiment, the overall shape of the ring grid steel frame 5 is a rotating body that is larger at the top and smaller at the bottom.

[0029] When designing the external dimensions of the ring-grid steel frame 5 , it is necessary to ensure that the overall outer diameter of the ring-grid steel frame 5 carrying the entire layer of lining plate 3 is adapted to the inner diameter of the conical shell 2 to be installed, so as to ensure smooth entry.

[0030] Specifically, the ring-grid steel frame 5 includes an annular plate 501 and a connecting plate 502. There are at least two annular plates 501 and they are not in the same plane. The connecting plates 502 are distributed along the circumference of the annular plates 501, and each connecting plate 502 is fixedly connected to at least two annular plates 501. This type of ring-grid steel frame 5 can reduce its own weight and ensure operating space while ensuring the overall rigidity of the hoisting.

[0031] In the above embodiment, the lifting component 6 can be a lifting lug. In order to maintain the stability of lifting, the number of the lifting lugs is preferably not less than three, and the ring-grid steel frame 5 is distributed at equal angles in the circumferential direction to cooperate with the hook of the overhead crane to realize the lifting and transfer of the entire ring-grid steel frame 5.

[0032] See also Figure 3 In the above embodiment, the installation platform 7 specifically includes a ring steel frame 701, a cross steel frame 702 and a grating 703; the ring steel frame 701 is fixed to the lower end of the ring grid steel frame 5, the end of the cross steel frame 702 is fixed in the ring steel frame 701, and the grating 703 is fixed to the top of the ring steel frame 701 and the cross steel frame 702. The function of the installation platform 7 is to provide an installation and operation platform for workers, and also to facilitate the subsequent backing glue pouring and other work.

[0033] The mounting member 8 of the same mounting unit is located above the positioning member 9 .

[0034] In the above embodiment, the mounting part 8 specifically includes a tool ear 801, a pin 802 and a cotter pin 803. The tool ears 801 are fixed on the ring grid steel frame 5 in pairs. The tool ears 801 are provided with pin holes for the pins 802 to pass through horizontally. The pins 802 can pass through the liner ears 4 and the tool ears 801, so that the liner 3 and the mounting part 8 are snap-fitted. Ears are provided on both the mounting part and the liner, and the ears are connected by fixing pins, which is simple and easy to disassemble and assemble. When snapping, the liner ear 4 is placed in the gap between a pair of tool ears 801, and the pin holes on the liner ear 4 and the tool ear 801 are horizontally opposite, the pin 802 is inserted, and the cotter pin 803 is inserted at the end of the pin 802 to prevent the pin 802 from detaching. When releasing the snap connection, the cotter pin 803 is pulled out, and the pin 802 is pulled out of the tool ear 801 and the liner ear 4. See also Figure 4 The pin hole 804 on the tool lifting ear 801 is wide at the top and narrow at the bottom. The pin 802 can be cylindrical. The pin 802 is conveniently inserted from the wider upper part of the pin hole 804. Due to the gravity of the liner 3, the pin 802 falls into the narrow lower part of the pin hole 804, which is not easy to shake, and at the same time meets the requirements of convenient disassembly and stability.

[0035] In the above embodiment, the positioning member 9 specifically includes a nut 901 and a tightening bolt 902. The nut 901 is fixed on the ring-grid steel frame 5. The tightening bolt 902 is connected to the inner thread of the nut 901. The tightening bolt 902 has a tightening end facing the inner side of the liner 3. After the entire ring-grid steel frame 5 together with the entire layer of liner 3 is hoisted into the interior of the conical shell 2, the tightening bolt 902 is rotated to move relative to the nut 901. The tightening end of the tightening bolt 902 presses the inner side of the liner 3, so that the outer surface of the liner 3 fits the inner surface of the conical shell 2, which is convenient to operate and has high installation efficiency.
