Therefore, the locking mechanism 4 is arranged, so that the first state and the second state of the dust cover assembly 1 can be effectively switched, meanwhile, the sealing performance of the dust cover assembly 1 in the first state can be guaranteed, and the walking wheels 5 are prevented from being exposed due to misoperation.
Specifically, one of the first cover 11 and the second cover 12 is movably provided on the vehicle body 7, and the locking mechanism 4 includes a bracket 41, a rotating member 42, and a locking piece 43.
Further, the bracket 41 is provided on the vehicle body 7 or the hood assembly 1. In other words, the bracket 41 may be mounted on the vehicle body 7 or provided on one of the first cover 11 and the second cover 12.
Specifically, the rotating member 42 is rotatably inserted through the bracket 41. For example, the holder 41 is provided with a through hole, and the rotary member 42 is rotatably provided on the holder 41 through the through hole.
Specifically, the locking piece 43 is fixed at one end of the rotating member 42 to rotate synchronously with the rotating member 42, and in the locked state, the locking piece 43 cooperates with the first cover 11 or the second cover 12 to limit the freedom of movement of the movable first cover 11 or the second cover 12.
For example, the bracket 41 is mounted on the vehicle body 7, one of the first cover 11 and the second cover 12 is movable, and in the locked state, the locking piece 43 cooperates with the movable first cover 11 or the second cover 12 to restrict the degree of freedom of movement thereof.
For another example, one of the first housing 11 and the second housing 12 can be moved, the bracket 41 is mounted on the fixed first housing 11 or the fixed second housing 12, and the fixing locking piece 43 cooperates with the movable first housing 11 or the movable second housing 12 to limit the freedom of movement.
For another example, one of the first housing 11 and the second housing 12 may be movable, the bracket 41 may be mounted on the movable first housing 11 or the movable second housing 12, and the locking piece 43 may cooperate with the fixed first housing 11 or the fixed second housing 12 to limit the freedom of movement of the movable first housing 11 or the movable second housing 12.
Specifically, in the locked state, the locking piece 43 abuts against the outer peripheral wall of the first cover 11 or the second cover 12. For example, as shown in fig. 4, the first cover 11 is fixed in the vehicle body 7, the second cover 12 is movable, the bracket 41 is mounted on the second cover 12, a flange is provided on an end surface of the first cover 11, and the locking piece 43 is stopped against an outer peripheral wall of the flange to limit the freedom of movement of the second cover 12. Therefore, the operation is simple, and the working efficiency can be improved.
Preferably, the end surface of the bracket 41 is provided with one of the positioning groove 422a and the positioning hole. For example, when the positioning groove 422a is provided on the end surface of the bracket 41, the positioning hole matching with the positioning groove 422a is provided on the end surface of the rotary member 42 contacting with the bracket 41. Alternatively, when the end surface of the bracket 41 is provided with a positioning hole, the end surface of the rotating member 42 contacting the bracket 41 is provided with a positioning groove 422a matching with the positioning hole. When the positioning groove 422a is engaged with the positioning hole, the rotary member 42 cannot rotate relative to the bracket 41.
Specifically, the rotating member 42 includes a first member 421, a second member 422, and a first elastic member 423.
The first member 421 is rotatably and movably disposed in the mounting hole. In other words, the first member 421 can not only rotate relative to the bracket 41, but also move relative to the bracket 41.
The second component 422 is provided with the other one of the positioning groove 422a and the positioning hole, which is engaged with or disengaged from the positioning groove 422a, for example, if the positioning hole is provided on the end surface of the bracket 41, the positioning groove 422a is correspondingly provided on the rotary member 42, and when the locking mechanism 4 is in a normal state, the positioning hole is engaged with the positioning groove 422a, and when the locking mechanism is unlocked, the positioning hole is disengaged from the positioning groove 422 a.
Further, the second part 422 is matched with the first part 421, the first part 421 moves to drive the second part 422 to move synchronously, and the locking piece 43 is arranged at one end of the second part 422 far away from the bracket 41 through the connecting piece 44. For example, the first member 421 and the second member 422 are engaged through the axle hole, the first member 421 can drive the second member 422 to rotate and move, the connecting member 44 is specifically a connecting bolt, and the locking plate 43 is fixed at an end of the second member 422 far away from the bracket 41 through the connecting bolt.
The two ends of the first elastic member 423 are respectively stopped against the second member 422 and the locking piece 43 and normally push the second member 422 to move toward the bracket 41. Therefore, when the locking mechanism 4 is in a normal state, the first elastic member 423 keeps the positioning groove 422a and the positioning hole in a matching state, so that the rotating member 42 cannot rotate relative to the bracket 41, and the reliability of the locking mechanism 4 is improved.
Specifically, the first elastic member 423 is a spring externally fitted to the connecting member 44, and thus, the reliability of the locking mechanism 4 can be improved.
Optionally, the outer peripheral wall of the first part 421 is provided with a locking groove 421a, the second part 422 is provided with a matching hole 422b, and the inner peripheral wall of the matching hole 422b is provided with a locking block extending into the locking groove 421 a. Therefore, through the matching of the locking slot 421a and the matching hole 422b, the first component 421 can not only drive the second component 422 to rotate, but also drive the second component 422 to move relative to the bracket 41.
When the dust cover assembly 1 needs to be moved, the first component 421 is pushed at first, the first component 421 drives the second component 422 to move and compress the first elastic member 423 through the matching of the fixture block and the clamping groove 421a, so that the positioning groove 422a and the positioning hole are disengaged, then the first component 421 is rotated and drives the locking plate 43 to rotate so as to realize unlocking, and at this time, the locking mechanism 4 resets after the first component 421 is released. This simplifies the operation and further improves the practicability of the locking mechanism 4.
It is understood that the structure of the locking mechanism 4 is not limited to this, and the locking mechanism 4 may be formed in any structure, for example, the locking mechanism 4 may be a matching structure of a snap and a snap groove, which are separated when the locking mechanism 4 is triggered so that the first cover 11 and the second cover 12 can move relatively, as long as it is achieved that the first cover 11 and the second cover 12 can move relatively when the locking mechanism 4 is in the locking state to position the first cover 11 and the second cover 12 and the locking mechanism is switched to the unlocking state.
According to the maintenance method of the straddle-type monorail train 100 of the embodiment of the invention, the straddle-type monorail train 100 is the straddle-type monorail train 100 according to the embodiment of the invention, and the maintenance method comprises the following steps: lifting the straddle monorail train 100 off the track beam to separate the traveling wheels 5 from the track beam; switching the locking mechanism 4 to the unlocked state; controlling the movable cover body and the electric appliance cabinet cover 6 to move so as to expose the walking wheels 5; the running wheels 5 are taken out of the vehicle body 7.
