DETAILED DESCRIPTION
[0062] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model more clear, the technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0063] Embodiment 1
[0064] As Figure 1 And Figure 2As shown, the embodiment provides a checking vehicle parking device, which comprises a checking vehicle fast parking mechanism, the checking vehicle fast parking mechanism comprises a blocking block 101, a fixed shaft 102, a rotating shaft 103, a sliding shaft 104, a dovetail groove sliding group 105, a bolt 106, and a butterfly bolt 107.
[0065] The dovetail groove sliding group 105 is rotationally connected to the driving box, and comprises a rotating groove body 1051 and a sliding block 1052. One end of the rotating groove body 1051 is rotationally connected to the driving box mounting plate 201, and the sliding block 1052 is slidingly connected to the rotating groove body 1051 and can slide along the rotating groove body 1051. In this embodiment, the rotating groove body 1051 is provided with a dovetail groove, and the sliding block 1052 is matched therewith, so that the sliding block 1052 can stably slide in the dovetail groove and will not fall out.
[0066] The rotating groove body 1051 is connected to one end of the rotating shaft 103 by a screw, the blocking block 101 is connected to the other end of the rotating shaft 103 by a screw, and the rotating shaft 103 passes through the driving box mounting plate 201 and is rotationally connected to the driving box mounting plate 201. In this way, when the rotating groove body 1051 rotates, the rotating shaft 103 and the blocking block 101 will rotate together, realizing the rotation function of the blocking block 101.
[0067] The driving box mounting plate 201 is provided with a pin hole, and the bolt 106 is detachably installed in the pin hole. The bolt 106 is located below the dovetail groove sliding group 105. When the checking vehicle is running, the bolt 106 is inserted into the pin hole, the bolt 106 supports the rotating groove body 1051 to avoid rotation, thereby avoiding the blocking block 101 from contacting the track 401.
[0068] One end of the sliding block 1052 away from the rotating groove body 1051 is connected to one end of the fixed shaft 102 by a screw, and the blocking block 101 is connected to the other end of the fixed shaft 102 by a screw. When the sliding block 1052 slides along the rotating groove body 1051, the blocking block 101 will move together.
[0069] The rotating groove body 1051 is connected to one end of the sliding shaft 104 by a screw, the blocking block 101 is connected to the other end of the sliding shaft 104 by a screw, a slot hole is arranged on the blocking block 101, a screw connected with the sliding shaft 104 is arranged in the slot hole in a sliding manner, and the length direction of the slot hole is consistent with the direction of the track 401. The fixed shaft 102, the sliding shaft 104 and the dovetail groove sliding group 105 form a horizontal moving pair, so as to realize the displacement of the blocking block 101 in the horizontal direction.
[0070] The butterfly bolt 107 is connected between the sliding block 1052 and the rotating groove body 1051, when the butterfly bolt 107 is tightened, the sliding block 1052 will be fixed on the rotating groove body 1051 and cannot slide.
[0071] When the inspection vehicle is running, the dovetail groove sliding group 105 is fixed by the bolt 106, and the butterfly bolt 107 is locked to fix the sliding block 1052 of the dovetail groove sliding group 105, so as to prevent the blocking block 101 from interfering with the track 401 plane.
[0072] When temporary parking is needed, the bolt 106 is removed, the dovetail groove sliding group 105 is in an active state, the rotating groove body 1051 can rotate freely, the butterfly bolt 107 is loosened, the sliding block 1052 of the dovetail groove sliding group 105 can move, and the blocking block 101 can move freely. At this time, the dovetail groove sliding group 105 plays a guiding and limiting role, and the blocking block 101 can move with the sliding block 1052 of the dovetail groove sliding group 105. The operator places the blocking block 101 on the track 401, starts the inspection vehicle, the positions of the blocking block 101 and the sliding block 1052 are fixed, the drive box, the rotating groove body 1051 and the sliding shaft 104 move forward, the track wheel 501 of the inspection vehicle is pressed on the blocking block 101, and the parking purpose is realized.
[0073] During the movement of the inspection vehicle to the blocking block 101, the relative positions between the inspection vehicle and the blocking block 101 change, so the slot hole on the blocking block 101 is needed to adapt to the change, prevent the blocking block 101 from moving with the inspection vehicle, separate the blocking block 101 from the inspection vehicle, and realize the parking purpose.
[0074] In the embodiment, the blocking block 101 is provided with a circular arc surface, so that the track wheel 501 can be pressed on the blocking block 101. The blocking block 101 is made of cast iron, which is used to prevent damage to the track 401, increase the roughness and contact area required for parking, and improve the stability of parking.
[0075] The parking mechanism changes the contact area and roughness of the track wheel 501 with the track 401 to achieve fast parking, so the blocking block 101 is the most core component in the entire mechanism, which realizes the parking function.
[0076] However, such mechanism is suitable for parking in a relatively horizontal and no headwind condition. If the inspection vehicle is parked on a steep slope or in a strong headwind condition, or needs to be parked temporarily for a short time and the staff leaves the inspection vehicle, an auxiliary parking mechanism is needed. The auxiliary parking mechanism has the characteristics of the fast parking mechanism, but is more stable and reliable.
[0077] As shown in Figure 3 and Figure 4 , the auxiliary parking mechanism includes a base 308 and a blocking block 309. The base 308 is magnetized and can be magnetically attracted to the track 401. The blocking block 309 is hinged to the base 308. The blocking block 309 is an obtuse angle L-shaped structure, which includes an inclined plate 3091 and a bottom plate 3092 connected to the lower end of the inclined plate 3091. The included angle between the inclined plate 3091 and the bottom plate 3092 is an obtuse angle. The inclined plate 3091 is hinged to the base 308. When the bottom plate 3092 is in contact with the bottom track 401, the upper end of the inclined plate 3091 is in abutment with the top track 401. The inclined plate 3091 and the bottom plate 3092 are integrally formed.
[0078] When there is no blocking, there is a gap between the bottom plate 3092 of the blocking block 309 and the bottom track 401, and between the inclined plate 3091 of the blocking block 309 and the top track 401. When blocking, the operator only needs to place the auxiliary parking mechanism on the track 401 and make the blocking block 309 contact with the track wheel 501. When the track wheel 501 is parked on the bottom plate 3092 of the blocking block 309, the blocking block 309 will rotate due to the weight of the inspection vehicle. The upper end of the inclined plate 3091 of the blocking block 309 will press the top track 401, and because of the existence of the force arm, the pressure on the top will be greater, thereby obtaining greater friction, and finally making the mechanism reach a self-locking state to achieve the purpose of blocking. The auxiliary parking mechanism can ensure that the inspection vehicle is parked stably on a steep slope or in a strong headwind condition, or needs to be parked temporarily for a short time and the staff leaves the inspection vehicle.
[0079] The auxiliary parking mechanism can be arranged simultaneously with the fast parking mechanism of the inspection vehicle, and can be arranged and act on different track wheels 501.
[0080] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
