[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The embodiment of the present application discloses a jaw crusher upper pulley assembly tool. Figure 1 and Figure 2The upper pulley assembly tool of the jaw crusher includes a mounting column 1 for detachably fixedly mounted on the main shaft 2. The mounting column 1 is mounted at one end of the main shaft 2, and the mounting column 1 is coaxial with the main shaft 2. A pressure block 4 is slidably mounted on the mounting column 1. The pressure block 4 is provided with a mounting hole 41 for the main shaft 2 to pass through. The mounting column 1 is passed through the mounting hole 41. The mounting column 1 is provided with a driving member 5 for driving the pressure block 4 to slide, and the driving member 5 is located on the side of the pressure block 4 away from the main shaft 2. The operator first fixes the mounting column 1 on the end of the main shaft 2 and makes the mounting column 1 parallel to the main shaft 2, then passes the pulley 3 through the mounting column 1 and sleeves it onto the main shaft 2; then sleeves the pressure block 4 on the mounting column 1 so that the pressure block 4 and the side of the pulley 3 away from the main shaft 2 abut against each other; finally, mounts the driving member 5 on the mounting column 1, controls the driving member 5 to drive the pressure block 4 to slide and approach the main shaft 2, and the pressure block 4 can press the pulley 3 on the main shaft 2 along the axial direction of the main shaft 2, thereby realizing the installation of the pulley 3, avoiding the damage of the pulley 3 and the main shaft 2 caused by axial striking with tools such as a sledgehammer, extending the service life of the equipment, improving the assembly efficiency of the pulley 3, reducing the production cost, realizing the fast, accurate and lossless installation of the pulley 3, improving the performance and use effect of the equipment, and reducing the damage to the pulley 3 during assembly as a whole.

[0034] The pressing block 4 is annular, the pressing block 4 and the mounting column 1 are coaxial, the pulley 3 is located on the side of the pressing block 4 close to the main shaft 2, the side wall of the mounting column 1 is provided with a thread, further, the thread on the side wall of the mounting column 1 is an M36T-type thread, the mounting column 1 is a screw rod, the driving member 5 is provided with a threaded hole adapted to the thread of the mounting column 1, and the mounting column 1 is penetrated into the threaded hole. By rotating the driving member 5, the driving member 5 can slide along the length direction of the mounting column 1 and drive the pressing block 4 close to the main shaft 2.

[0035] In order to facilitate the rotation of the driving member 5, the driving member 5 can be a hand wheel; the hand wheel is relatively common, and the operator can rotate the hand wheel with relatively less effort, which is convenient for driving the pressing block 4 to slide, thereby reducing the labor intensity of the operator.

[0036] Reference Figure 1 and Figure 2, the mounting column 1 is fixedly connected to one end of the main shaft 2 with a mounting seat 6, and three fixing holes 61 are provided on the mounting seat 6, and fixing bolts 7 are provided in the fixing holes 61, and there are four or more fixing holes 61. The three fixing holes 61 are arranged circumferentially around the mounting column 1. Screw holes are provided on the end wall of the main shaft 2 corresponding to the fixing holes 61, and the screw holes are adapted to the fixing bolts 7, and the fixing bolts 7 are M16 bolts. When the operator installs the mounting seat 6 on the main shaft 2, the fixing hole 61 and the screw hole can be aligned, and then the fixing bolt 7 can be screwed into the screw hole. The fixing bolt 7 passes through the fixing hole 61 and is threadedly connected to the main shaft 2, so that the mounting seat 6 can be firmly installed on the main shaft 2, thereby realizing the installation and connection between the mounting column 1 and the main shaft 2. After loosening and removing the locking bolt, it is convenient to remove the mounting column 1 and the mounting column 1 from the main shaft 2.

[0037] The mounting seat 6 is cylindrical, and the mounting seat 6 is coaxial with the mounting column 1. The diameter of the mounting hole 41 is larger than the diameter of the mounting seat 6, and the diameter of the mounting seat 6 is smaller than or equal to the diameter of the main shaft 2. When the control pressure block 4 is close to the main shaft 2, the pressure block 4 can be sleeved on the mounting seat 6, and the pressure block 4 can be against the pulley 3, reducing the control pressure block 4 close to the main shaft 2, and ensuring that the pulley 3 is sleeved on the main shaft 2.

[0038] Reference Figure 1 and Figure 2 A flexible pad 42 is fixedly provided on one side of the pressing block 4 away from the driving member 5. The flexible pad 42 may be a rubber pad. The flexible pad 42 is arranged between the pressing block 4 and the pulley 3, which is beneficial for the pressing block 4 to uniformly apply pressure to the pulley 3.

[0039] In order to guide the sliding of the pressing block 4, a limiting member 8 is welded on one side of the pressing block 4 close to the driving member 5, and a limiting hole 81 is formed through the limiting member 8. The diameter of the limiting hole 81 matches the mounting column 1, and the mounting column 1 is passed through the limiting hole 81. With the help of the limiting member 8, the pressing block 4 can be guided to ensure the stable contact between the pressing block 4 and the pulley 3.

[0040] Reference Figure 2 and Figure 3 Furthermore, the limiting member 8 is a plane bearing. When the hand wheel is against the limiting member 8, the plane bearing can be driven to rotate when the hand wheel rotates, and the operator can rotate the hand wheel more easily.

[0041] A bearing plate 9 is integrally welded to one side of the hand wheel close to the plane bearing. The bearing plate 9 increases the contact area with the plane bearing and reduces the pressure on the plane bearing.

[0042] The implementation principle of the pulley assembly tooling on the jaw crusher of the embodiment of the present application is: the operator first fixes the mounting column 1 on the end of the main shaft 2, and makes the mounting column 1 parallel to the main shaft 2, and then passes the pulley 3 through the mounting column 1 and sleeves it onto the main shaft 2; then sleeves the pressure block 4 on the mounting column 1, so that the pressure block 4 and the side of the pulley 3 away from the main shaft 2 are against each other; finally, the driving member 5 is installed on the mounting column 1, and the driving member 5 is controlled to drive the pressure block 4 to slide and approach the main shaft 2, and the pressure block 4 can press the pulley 3 on the main shaft 2 along the axial direction of the main shaft 2, thereby realizing the installation of the pulley 3 and reducing the damage to the pulley 3 during assembly as a whole.
