[0032] Figure 1 It is a schematic diagram of the connection relationship between two adjacent trolleys in the baggage sorting machine trolley assembly; Figure 2 for Figure 1 The top view of the connection state of two adjacent trolleys is shown in FIG. Figure 1 and Figure 2 As shown, there are two adjacent trolleys 8, a mounting plate 9 is fixed to the tail of one trolley 8, a boss 10 is fixed on the mounting plate 9, and a radial spherical bearing 11 is embedded in the boss 10, and a connecting plate 12 is fixed to the head of the other trolley 8, the connecting plate 12 includes two horizontal plates arranged in parallel, and two vertical plates arranged in parallel between the two horizontal plates, the boss 10 is inserted between the two vertical plates in the direction of the arrow in the figure, and then the eccentric bolt 13 is passed through the vertical plate and the radial spherical bearing 11 embedded in the boss 10, and the interference connection with the radial spherical bearing 11 is completed at the same time. The eccentric bolt 13 includes an eccentric disk 131 and a screw rod 132 that are fixedly connected, and the screw rod 132 is provided with threads only on the outer wall of the end away from the eccentric disk 131. After the eccentric bolt 13 is interference-connected with the radial spherical bearing 11, the two ends are exposed to the vertical plates on both sides. In order to limit the position of the eccentric bolt 13, a nut 14 is connected to the threaded end thereof, and the nut 14 is made to abut against the vertical plate on that side. The width of the boss 10 is smaller than the spacing between the two vertical plates. In order to further limit the position of the eccentric bolt 13, a sleeve 15 is also provided on the side of the boss 10 facing the nut 14, so that the eccentric bolt 13 passes through the radial spherical bearing 11 and the sleeve 15, and then passes through the vertical plate 14. Figure 2 The vertical plate on the right side of the middle part is abutted against the sleeve 15, so that the sleeve 15 and the nut 14 are respectively abutted against the two opposite side surfaces of the same vertical plate, so that after the eccentric bolt 13 is connected to the radial spherical bearing 11, both sides along the extension direction cannot move.

[0033] Figure 3 This is an exploded view of the eccentric bolt removal tool according to one embodiment of the utility model in use; Figure 4 for Figure 3A top view of the eccentric bolt removal tool in use; Figure 5 for Figure 3 A side view of the eccentric bolt removal tool in use; Figure 6 for Figure 4 A partial enlarged view of the connection relationship between the guide sleeve and the eccentric bolt is shown.

[0034] like Figure 3-Figure 6 As shown, the removal tool of the eccentric bolt 13 includes a guide sleeve 1, a limiting push rod 2, a sleeve 3 and a push rod 4. A receiving groove 101 is provided on the first end face of the guide sleeve 1 in the extension direction, and the receiving groove 101 is used to accommodate the eccentric disk 131 of the eccentric bolt 13 and has an interference fit with the eccentric disk 131; the limiting push rod 2 is bent, and the first end side wall of the limiting push rod 2 abuts against the second end of the guide sleeve 1 in the extension direction, and the second end of the limiting push rod 2 is located on one side of the screw 132 of the eccentric bolt 13 and keeps a certain distance from the screw 132; the sleeve 3 is fixedly connected to the second end of the limiting push rod 2, and a connecting hole is provided through the sleeve 3, and the extending direction of the connecting hole is the same as the extending direction of the guide sleeve 1; the push rod 4 is inserted into the connecting hole and is movably connected to the sleeve 3, and the end of the push rod 4 facing the guide sleeve 1 is used to abut against the screw 132.

[0035] When the eccentric bolt 13 needs to be removed, the nut 14 that cooperates with it to limit the position is first removed, and the end of the guide sleeve 1 with the accommodating groove 101 is aligned with the end of the eccentric disk 131 of the eccentric bolt 13, that is, the end away from the nut 14, and the guide sleeve 1 is pressed to sleeve the eccentric disk 131 of the eccentric bolt 13 into the accommodating groove 101, and the eccentric disk 131 of the eccentric bolt 13 is interference-connected with the accommodating groove 101, and the side wall of the first end of the limiting push rod 2 is abutted against the free end of the guide sleeve 1, so that the sleeve 3 fixed on the second end is aligned with the end of the screw rod 132 of the eccentric bolt 13, and the push rod 4 is inserted into the sleeve 3 and moves relative to the sleeve 3 toward the eccentric bolt 13, and finally abuts against the end face of the free end of the screw rod 132 of the eccentric bolt 13. Continue to move the push rod 4 toward the eccentric bolt 13, and the push rod 4 will continue to apply external force to the eccentric bolt 13. Under the action of a sufficiently large external force, the eccentric bolt 13 moves in the receiving groove 101 toward the guide sleeve 1, and finally disengages from the radial spherical bearing 11, releasing the interference connection with the radial spherical bearing 11. Then, move the push rod 4 away from the eccentric bolt 13, disengage from the eccentric bolt 13, remove the limit push rod 2, release the contact with the guide sleeve 1, remove the guide sleeve 1 and the eccentric bolt 13 inserted in the receiving groove 101 of the guide sleeve 1, and then pull out the eccentric bolt 13, thus completing the removal of the eccentric bolt 13.

[0036] By using the eccentric bolt removal tool of the utility model, one end of the eccentric disk 131 of the eccentric bolt 13 is inserted into the accommodating groove 101 of the guide sleeve 1, one end of the limiting push rod 2 is abutted against the guide sleeve 1, and the other end is fixed to the sleeve 3 and a pushing rod 4 is inserted into the sleeve 3, so that the pushing rod 4 is abutted against one end of the screw rod 132 of the eccentric bolt 13. In the process of moving the pushing rod 4 along the sleeve 3, an external force is applied to the eccentric bolt 13, so that the eccentric bolt 13 further penetrates into the accommodating groove 101 of the guide sleeve 1 under the action of the external force, and finally detaches from the radial spherical bearing 11, thereby realizing the disassembly of the eccentric bolt 13. The overall structure of the removal tool is simple, the space occupied is small, the operation is convenient, and the operator is convenient to operate quickly in the narrow space between adjacent trolleys.

[0037] like Figure 3 , Figure 4 As shown, in this embodiment, the guide sleeve 1 is a hollow cylinder as a whole, and the inner diameter of the receiving groove 101 matches the cross-sectional diameter of one end of the eccentric disk 131 of the eccentric bolt 13, so that the two can be connected by interference. The limiting push rod 2 is bent into a C shape as a whole, and does not interfere with the trolley 8, the mounting plate 9 and the connecting plate 12 connected to the trolley 8, etc. Figure 4 The inner side wall of the left end of the middle limit push rod 2 abuts against the guide sleeve 1, and the sleeve 3 is fixed on the right end, and keeps a certain distance from the eccentric bolt 13. After the limit push rod 2 abuts against the guide sleeve 1, the sleeve 3 is coaxially arranged with the screw 132 of the eccentric bolt 13, and the push rod 4 is also coaxially arranged with the screw 132 after being inserted into the sleeve 3, and the sleeve 3 plays a guiding role on the push rod 4, ensuring that the push rod 4 applies a pushing force to the screw 132 along the axial direction of the sleeve 3, that is, along the axial direction of the screw 132. According to the actual application, the specific shapes and sizes of the guide sleeve 1, the limit push rod 2, the sleeve 3 and the push rod 4 can be matched and adjusted, as long as the guide sleeve 1 can accommodate the eccentric bolt 13, the limit push rod 2 can stably clamp the guide sleeve 1, and the push rod 4 can stably apply external force to the eccentric bolt 13 along the sleeve 3, and under the above cooperation, the eccentric bolt 13 can be smoothly released from the radial spherical bearing 11.

[0038] Optionally, the inner wall of the sleeve 3 is provided with an internal thread; the outer wall of the push rod 4 is provided with an external thread, and the push rod 4 is threadedly connected with the sleeve 3. The threaded connection is set to rotate the push rod 4 to move it toward the guide sleeve 1, so as to apply an external force to the eccentric bolt 13, and the rotational motion of the push rod 4 is converted into a linear motion, which does not require much manpower, is labor-saving and convenient, and the threaded connection makes the connection between the push rod 4 and the sleeve 3 more stable.

[0039] Optionally, the eccentric bolt 13 removal tool further comprises a contact top block 5, the end surface of the first end of the contact top block 5 is provided with a connection hole, the connection hole is used for threaded connection with the screw rod 132, and the second end of the contact top block 5 abuts against one end of the push rod 4 that faces the guide sleeve 1. The push rod 4 directly abuts against the eccentric bolt 13, and in the process of the push rod 4 applying external force, the contact position between the eccentric bolt 13 and the push rod 4 may be damaged. With the help of the contact top block 5, the external force applied by the push rod 4 is transmitted to the eccentric bolt 13 after passing through the contact top block 5, thereby protecting the eccentric bolt 13 from damage and being reusable.

[0040] like Figure 4 As shown, in the present embodiment, a connecting hole is provided on the left end face of the contact top block 5 and extends for a distance, and an internal thread is provided on the inner wall of the connecting hole to match the screw rod 132 portion of the eccentric bolt 13. After the push rod 4 moves toward the guide sleeve 1, it abuts against the right end face of the contact top block 5, and the push rod 4 continues to rotate, so that the push rod 4 continues to apply external force to the contact top block 5, and finally pushes the contact top block 5 and the eccentric bolt 13 threadedly connected thereto toward the depth of the accommodating groove 101 of the guide sleeve 1, thereby releasing the eccentric bolt 13 from the radial spherical bearing 11. After the eccentric bolt 13 is separated from the radial spherical bearing 11, the push rod 4 is rotated in the reverse direction to separate the push rod 4 from the contact top block 5, the limit push rod 2 is removed, and the contact top block 5 is rotated to release the threaded connection between the contact top block 5 and the screw rod 132 of the eccentric bolt 13, and then the guide sleeve 1 and the eccentric bolt 13 inserted in the guide sleeve 1 are removed, and finally the eccentric bolt 13 is pulled out from the receiving groove 101 of the guide sleeve 1, and the removal of the eccentric bolt 13 is finally completed. According to the actual application, the specific shape and size of the contact top block 5 can be adjusted, as long as one end of it is connected to the screw rod 132 of the eccentric bolt 13, and the other end is in contact with the push rod 4 to transmit external force to the eccentric bolt 13, and the eccentric bolt 13 can be smoothly separated from the radial spherical bearing 11 under the action of external force.

[0041] Figure 7 for Figure 4 A partial enlarged view of the connection relationship between the contact top block and the eccentric bolt is shown; Figure 8 for Figure 4 The partial enlarged view of the connection between the contact top block and the push rod is shown. Figure 7 and Figure 8As shown, optionally, the contact top block 5 includes a first section 51, a second section 52 and a third section 53 connected in sequence, the free end of the first section 51 is provided with the connection hole, the third section 53 is in contact with the push rod 4, the cross-sectional diameter of the first section 51 is smaller than the cross-sectional diameter of the third section 53, and the cross-sectional diameter of the second section 52 gradually increases in the direction toward the third section 53. This arrangement enables the end of the contact top block 5 connected to the eccentric bolt 13 to have a smaller cross-sectional area, so that when the eccentric bolt 13 moves toward the guide sleeve 1 and disengages from the radial spherical bearing 11 under the action of external force, the cross-sectional area of ​​the contact top block 5 is prevented from being too large and Figure 2 The mounting plate 9 in the middle interferes with the disassembly of the eccentric bolt 13. In addition, the end of the contact top block 5 that abuts against the push rod 4 has a larger cross-section, which can not only ensure its own structural strength, but also have a sufficiently large contact area with the push rod 4 to facilitate stable force transmission.

[0042] like Figure 7 As shown, in this embodiment, the contact top block 5 is composed of a first section 51, a second section 52 and a third section 53 from left to right. A connecting hole is provided at the left end of the first section 51, which is threadedly connected to the eccentric bolt 13. The cross-sectional diameter of the outer wall is slightly larger than the diameter of the eccentric bolt 13. The cross-sectional diameter of the third section 53 is larger than that of the first section 51. The cross-sectional diameter of the left end of the second section 52 is the same as that of the first section 51, and the cross-sectional diameter of the right end is the same as that of the third section 53. The cross-sectional diameter in the middle gradually increases.

[0043] Optionally, a positioning hole 54 is provided on the end surface of the free end of the third section 53, and the push rod 4 is inserted into the positioning hole 54. When the positioning hole 54 is provided, the push rod 4 is inserted into the positioning hole 54, and after abutting against the inner wall of the positioning hole 54, the push rod 4 is further rotated to rotate relative to the sleeve 3 and generate a linear movement toward the contact top block 5, which can ensure the stability of the abutment between the push rod 4 and the contact top block 5, so that during the rotation of the push rod 4, its end portion is always located in the positioning hole 54, and will not be separated from the surface of the contact top block 5.

[0044] like Figure 7 and Figure 8 As shown, in this embodiment, a positioning hole 54 is opened at the center position of the right end surface of the third section 53 of the contact top block 5, so that after the push rod 4 is inserted into the positioning hole 54, it is coaxially arranged with the contact top block 5, which is conducive to the stable transmission of force.

[0045] Optionally, the cross-sectional diameter of one end of the push rod 4 inserted into the positioning hole 54 gradually decreases in the direction toward the contact top block 5; the cross-sectional diameter of the positioning hole 54 gradually decreases in the direction away from the push rod 4. This arrangement reduces the contact area between the push rod 4 and the contact top block 5 in the positioning hole 54, thereby increasing the pressure on the contact top block 5 under the premise of applying the same force to the push rod 4, and then after the force is transmitted to the eccentric bolt 13, the eccentric bolt 13 can be more quickly and conveniently separated from the radial spherical bearing 11.

[0046] like Figure 7 and Figure 8 As shown, in this embodiment, the end of the push rod 4 that contacts the top block 5 is set to a conical structure, and the cone vertex angle is 60°. Correspondingly, the positioning hole 54 is also set to a conical shape. After the push rod 4 is inserted into the positioning hole 54, its outer wall fits with the inner wall of the positioning hole 54. According to actual application conditions, the specific angle of the cone vertex angle of the end of the push rod 4 inserted into the positioning hole 54 can be adjusted, and it can also be set to other structures other than a cone, and the positioning hole 54 is adjusted accordingly.

[0047] Optionally, the end of the push rod 4 away from the guide sleeve 1 is connected with a handle 6. The handle 6 is provided to facilitate operation and force generation during the process of rotating the push rod 4.

[0048] like Figure 4 As shown, in this embodiment, the right end of the push rod 4 is threadedly connected with a hexagonal nut to serve as a handle 6. When the push rod 4 is rotated, the hexagonal nut can be turned with the help of a wrench to rotate the push rod 4. According to actual application conditions, the handle 6 can be set to any shape and size, as long as it is convenient to apply external force to the handle 6 and rotate the push rod 4.

[0049] Optionally, a limiting plate 7 is fixed to the side wall of the first end of the limiting push rod 2, and the limiting plate 7 abuts against the guide sleeve 1. In this arrangement, the limiting plate 7 can abut against guide sleeves 1 of different sizes without being limited by the shape and size of the inner wall of the limiting push rod 2.

[0050] like Figure 3 , Figure 4 As shown, in this embodiment, the limiting plate 7 is set as a cubic plate body, fixed to the inner wall of the limiting top rod 2 facing the guide sleeve 1, the width of the limiting plate 7 is greater than the width of the limiting top rod 2, and the top of the limiting plate 7 is higher than the top of the limiting top rod 2. Moreover, the limiting plate 7 is set as a square. During installation, due to the obstruction of vision, the installation position and angle of the limiting plate 7 can be clearly determined by touching the top corner position of the limiting plate 7. According to the actual application, the specific shape and size of the limiting plate 7 can be adjusted.

[0051] Fig. 9 for Figure 3 An enlarged view of the guide sleeve 1 is shown. Fig. 9 As shown, optionally, a plug hole 102 is formed on the end surface of the second end of the guide sleeve 1; a plug post (not shown) is fixed on the limit plate 7, and the plug post is inserted into the plug hole 102. This arrangement ensures the stability of the contact between the limit plate 7 and the guide sleeve 1 by means of the plug connection between the plug post and the plug hole 102, and prevents the limit plate 7 from being separated from the guide sleeve 1 during the process of releasing the connection between the eccentric bolt 13 and the radial spherical bearing 11.

[0052] like Fig. 9 As shown, in this embodiment, the plug hole 102 is opened at a position where the end surface of the guide sleeve 1 passes through the axis and extends for a distance.

[0053] Optionally, the side wall of the guide sleeve 1 is provided with an avoidance groove 103. During the assembly process of a single trolley 8, fasteners such as bolts are used. The avoidance groove 103 is provided on the side wall of the guide sleeve 1 to avoid interference between the guide sleeve 1 and the fasteners on the trolley 8 when the guide sleeve 1 is sleeved on the eccentric bolt 13.

[0054] like Figure 4 and Fig. 9 As shown, in the present embodiment, most of the upper surface of the guide sleeve 1 is cut in the horizontal direction, so that the height of most of the upper surface of the guide sleeve 1 is reduced. At the same time, part of the accommodating groove 101 is also cut, so that the cross-section of the accommodating groove 101 is arc-shaped, and the arc is larger than a semicircle, so that the eccentric bolt 13 can be stably installed and interfered with the eccentric bolt 13. Figure 4 The distance between the upper surface of the middle guide sleeve 1, that is, the bottom of the avoidance groove 103 and the bolt on the trolley 8 is 2 mm. According to the actual application, the opening position and size of the avoidance groove 103 can be adjusted according to the interference situation. Fig. 9 The whole is cut horizontally in the middle, and can also be opened as a groove with inner walls around it.
