[0040] Embodiment 1:

[0041] like Figure 1-Figure 10 As shown, the assembled gate roller disassembly and assembly device includes a horizontal track 1, a horizontal trolley 2, a vertical lifting trolley 3, a lifting mechanism 4, a locking mechanism 5, and a pulling tool 6. The horizontal track 1 is fixed to the lower embedded part of the gate maintenance track with bolts, the horizontal trolley 2 is installed in the horizontal track 1; the vertical lifting trolley 3 is installed in the vertical track of the horizontal trolley 2; the lifting mechanism 4 is fixed to the horizontal trolley 2 and the vertical lifting trolley 3; the locking mechanism 5 is fixed to the horizontal track 1 and the horizontal trolley 2; and the pulling tool 6 is placed on the back side of the vertical lifting trolley 3.

[0042] like Figure 2-Figure 3 As shown, the horizontal track 1 includes a main beam 11, a transverse track 12, a support and adjustment assembly 13, a fixed baffle 14, etc. The main beam 11 is welded by a T-beam and a cantilever beam, both of which are steel plate welded parts. The transverse track 12 is fixed to the cantilever beam of the main beam 11 by bolt connection; there are 4 groups of support and adjustment assemblies 13, each group of support and adjustment assemblies 13 is composed of a screw, 2 nuts and a sleeve base, which supports and can adjust the horizontal track 1 to a horizontal state; the fixed baffle 14 is arranged at both ends of the transverse track 12, and is connected by bolts to prevent the horizontal trolley 2 from derailing.

[0043] like Figure 4 As shown, the horizontal trolley 2 includes a first groove roller 21, a first cross beam 22, a first longitudinal beam 23, a vertical track 24, a tie rod 25, and a support 26. The first groove roller 21 is a standard part, and its axle is connected to the first cross beam 22 as a whole; the first longitudinal beam 23 is welded to the first cross beam 22 as a whole; the vertical track 24 is two channel steel tracks, which are welded to the first longitudinal beam 23 as a whole; the tie rod 25 is a screw rod, which connects the two channel steel tracks of the vertical track 24 as a whole, in addition to enhancing the stability of the structure, it can also prevent the vertical lifting trolley 3 from derailing; the support 26 is a steel plate welded part, which is welded to the first cross beam 22 as a whole.

[0044] like Figure 5As shown, the vertical lifting trolley 3 includes a second groove roller 31, a second cross beam 32, a second longitudinal beam 33, a lifting rod 34, a lifting platform 35, and a drawing baffle 36. The second groove roller 31 is a standard part, and its wheel axle is connected to the second cross beam 32 as a whole; the second longitudinal beam 33 is welded to the second cross beam 32 as a whole; the lifting rod 34 is an inverted "U" shape, and is welded to the second cross beam 32 and the second longitudinal beam 33 as a whole; the lifting platform 35 is a steel plate welded part, arranged on the back side, and is welded to the second cross beam 32 and the second longitudinal beam 33 as a whole; the drawing baffle 36 is a steel plate welded part, and is welded to the lifting platform 35 as a whole.

[0045] The lifting mechanism 4 is a vehicle-mounted double-tooth hand-cranked jack with a rated lifting capacity of 1.0-2.0t.

[0046] like Figure 6 As shown, the locking mechanism 5 includes a single-ear screw 51, a hollow screw 52 and a double-ear screw 53. The single-ear screw 51 and the double-ear screw 53 are connected to the hollow screw 52 by threads. When the single-ear screw 51 and the double-ear screw 53 are fixed, the overall length can be adjusted within a certain range by rotating the hollow screw 52.

[0047] like Figure 7 As shown, the drawing tool 6 includes a crossbar 61 and a drawing rod 62. The crossbar 61 is a welded part of a channel steel and a flat steel plate, and has long waist-shaped holes at both ends; the drawing rod 62 is composed of a screw and a nut, and passes through the long waist-shaped hole of the crossbar 61.

[0048] The working principle of the present invention is as follows:

[0049] 1. Movement principle of internal components of the device: The main beam 11 of the horizontal track 1 is connected to the embedded parts of the gate inspection track by bolts, and the support adjustment component 13 is adjusted to achieve the overall horizontal state of the horizontal track 1. The horizontal trolley 2 can move horizontally forward and backward in the transverse track 12 of the horizontal track 1 through the first groove roller 21; the vertical lifting trolley 3 moves up and down on the vertical track 24 of the horizontal trolley 2 through the second groove roller 31, and the lifting rod 34 of the vertical lifting trolley 3 can lift heavy objects. The up and down movement of the vertical lifting trolley 3 is realized by the lifting mechanism 4.

[0050] 2. Principle of the device not tipping over:

[0051] (1) No tipping forward or backward: When the gate roller 7 is disengaged from the roller shaft 8, the gate roller 7 is completely moved to the lifting rod 34 of the vertical lifting trolley 3. The weight of the gate roller 7 is transferred to the horizontal track 1 through the vertical lifting trolley 3, the lifting mechanism 4, the horizontal trolley 2, etc. Since the right side is supported by the support adjustment component 13, the gate roller 7 will not tip backward. The force analysis is as follows: Figure 8, the weight G1 of the gate roller 7, the weight G2 of the horizontal track 1, the weight G3 of the horizontal trolley 2, and the weight G4 of the vertical lifting trolley 3. With the bolt as the fulcrum, the corresponding force arms of the above components are L1, L2, L3, and L4 respectively. In order to ensure that the entire device will not tip forward (because the weight of the lifting mechanism 4, the locking mechanism 5 and the pulling tool 6 is relatively small, and the center of gravity is located on the right side of the bolt, it is more conducive to not tipping over, which is temporarily ignored), it must meet the following requirements: G1*L1<(G2*L2+G3*L3+G4*L4), taking the weight G1=200Kg of the gate roller 7 with a diameter of 600mm as an example, L1=37mm, the weight G2=38Kg of the horizontal track 1, L2=655mm, the weight G3=18Kg of the horizontal moving trolley 2, L3=157mm, and the weight G4=10Kg of the vertical lifting trolley 3, L4=107mm. G1*L1<(G2*L2+G3*L3+G4*L4) can be satisfied, that is, the entire device will not tip forward. When the gate roller 7 moves toward the vertical lifting trolley 3 along the lifting rod 34 or the horizontal trolley 2 moves backward, the center of gravity of the gate roller 7 is on the right side of the fulcrum bolt, and it will not tip over.

[0052] (2) Not tilting left or right: Fig. 9 As shown, the weight of the entire device and the gate roller 7 is borne by the two bolts connecting the main beam 11 and the embedded parts of the inspection track and the four bolt support adjustment components 13. The center of gravity of the entire component and the gate roller 7 is on the center line and within the support range lines on both sides, and will not tip over to the left or right.

[0053] 3. Centering method for gate roller 7 during disassembly and assembly: The lifting rod 34 of the vertical lifting trolley 3 is mainly composed of an arc plate, a side plate and a support. The arc diameter of the arc plate at the top of the lifting rod 34 is 10-20mm smaller than the aperture of the gate roller 7. When the lifting rod 34 lifts the gate roller 7, the lifting mechanism 4 can lift the vertical lifting trolley 3, that is, lift the gate roller 7, so that the height of the gate roller 7 hole and the roller shaft 8 are consistent; when the gate roller 7 hole and the roller shaft 8 end face are tilted left and right, because the diameter of the arc plate at the top of the lifting rod 34 is slightly smaller than the aperture of the gate roller 7, the gate roller 7 can be manually rotated left and right on the arc plate at the top of the lifting rod 34 to achieve the centering of the gate roller 7 hole and the roller shaft 8.

[0054] 4. The gate roller 7 does not slip: the pulling tool 6 is placed on the inner side of the pulling baffle 36 of the vertical lifting trolley 3, the pulling rod 62 is inserted into the screw hole of the roller pressure cover plate of the gate roller 7 and tightened, and the nut on the pulling rod 62 is turned, and the gate roller 7 slowly moves from the roller shaft 8 to the lifting rod 34 of the vertical lifting trolley 3, so that the gate roller 7 can be pulled out from the roller shaft 8 and the gate roller 7 and the vertical lifting trolley 3 are fixed together, which can prevent the gate roller 7 from slipping.
