Detailed description of the invention
It should be noted that when not conflicting, the embodiment in the application and the feature in embodiment can be mutually combined.Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
According to embodiments of the present invention pack dolly, as illustrated in figs. 1 and 2, including underframe 10, rollover stand 20 and driving device 30, underframe 10 is provided with roller 11 so that underframe 10 may move；Rollover stand 20 can be arranged on underframe 10 turningly towards the side of underframe 10；Driving device 30 is arranged on underframe 10, and is driveably connected with rollover stand 20, is used for driving rollover stand 20 to overturn.
That applies technical solution of the present invention packs dolly, by being arranged below roller 11 at underframe 10, the rollover stand 20 that can overturn it is provided above towards the side of underframe 10 at underframe 10, underframe 10 is provided with driving device 30 be driveably connected with rollover stand 20, driving device 30 can drive rollover stand 20 to overturn in predetermined angle, thus power distribution cabinet being placed on after rollover stand 20 overriding is transported to predeterminated position, power distribution cabinet can be unloaded by controlling rollover stand 20 be placed on predeterminated position towards preset direction upset, without manually moving, effectively reduce the labor intensity of workman, and it can be avoided that power distribution cabinet is damaged car body and around accessory.
When being embodied as, rollover stand 20 has free end and hinged end, hinged end is hinged with the first end of underframe 10, and driving device 30 is driveably connected rollover stand 20 jack-up with the partial switching frame 20 between hinged end and free end or puts down the upset realizing rollover stand 20.
nullThe height on the hinged end distance ground of rollover stand 20 is identical with the height on underframe 10 upper surface distance ground，After making rollover stand 20 dig，The lower end of power distribution cabinet can touch ground，The hinged end of rollover stand 20 is provided with telescopic foot stool 21，Telescopic foot stool 21 can be extended or retracted along the plane residing for rollover stand 20，It is thus possible to the length according to power distribution cabinet is adjusted adapting to different power distribution cabinet length，The length of telescopic foot stool 21 slightly larger than the hinged end of rollover stand 20 to the distance on ground，After telescopic foot stool 21 is fully extended，When rollover stand 20 is dug，The bottom of rollover stand 20 and earth surface，The angle on telescopic foot stool 21 and ground is less than 90 °，So that the center of gravity of power distribution cabinet is all the time towards rollover stand 20 side，Power distribution cabinet is avoided to fall down towards the side relative with rollover stand 20 under effect of inertia when upset.
In order to when rollover stand 20 is dug, it is easy to move by a small margin pack dolly, thus power distribution cabinet being placed on predetermined position, it is provided with at least one in the bottom of telescopic foot stool 21 and supports wheel 22, alternatively, supporting wheel and 22 be provided with two, two support wheel 22 and arrange respectively close to the both sides of telescopic foot stool 21.When rollover stand 20 is dug, support wheel 22 with earth surface it is thus possible to bear the gravity of a part of power distribution cabinet, it is simple to pack dolly and move by a small margin forward or backward.
Driving device 30 includes: push rod 31, moving mass 32, screw rod 33 and motor 34, and one end of push rod 31 and the partial switching frame 20 between hinged end and free end are hinged, and the other end of push rod 31 is connected rotationally with moving mass 32；Screw rod 33 circumferentially direction is rotatably arranged on underframe 10, and moving mass 32 has the screw matched with screw rod 33, and moving mass 32 is set on screw rod 33 movably by this screw；Motor 34 is driveably connected with screw rod 33, and alternatively, type of drive can drive for gear, belt drives or chain drive, and embodiment of the present invention motor 34 adopts chain to drive with screw rod 33 to be connected.When motor 34 drives screw rod 33 to rotate, moving mass 32 moves thus apply thrust forward or pulling force backward to push rod 31 along the axial direction of screw rod, push rod 31 is movable thus driving rollover stand 20 to overturn in predetermined angle, it is achieved is dug by power distribution cabinet and falls.
In order to enable rollover stand 20 to stop at predeterminated position exactly when digging or fall, the first end near screw rod 33 is provided with the first travel switch 35, the second end near screw rod 33 is provided with the second travel switch 36, and the first end is positioned at the front portion of screw rod 33, and the second end is positioned at the rear portion of screw rod 33；First travel switch 35 and the second travel switch 36 are connected with motor 34 respectively, moving mass 32 touches the first travel switch 35 when moving forward to the first end along screw rod 33, the drive circuit of motor 34 is disconnected by the first travel switch 35, motor 34 is made to shut down, rollover stand 20 stops at the first predeterminated position, is namely in tip-up state；Moving mass 32 touches the second travel switch 36 when being moved rearwardly into the second end along screw rod 33, the drive circuit of motor 34 is disconnected by the second travel switch 36, making motor 34 shut down, rollover stand 20 stops at the second predeterminated position, namely falls and the state of underframe 10 upper surface keeping parallelism.It is capable of the accurate control to rollover stand 20 upturned position by arranging the first travel switch 35 and the second travel switch 36.
Due to power distribution cabinet heavier mass, driving device 30 there will be rock when driving rollover stand 20 to dig or fall, in order to be held turned over the frame 20 balance in switching process, the gimbal lever 40 it is provided with between underframe 10 and rollover stand 20, the gimbal lever 40 is provided with two, the Liang Gen gimbal lever 40 be arranged in parallel and lays respectively at the both sides of driving device 30, one end of the gimbal lever 40 is hinged with underframe 10, the other end of the gimbal lever 40 and the partial switching frame 20 between hinged end and free end are hinged, the gimbal lever 40 can elongate or shorten according to the flip angle of rollover stand 20 thus rollover stand 20 is played certain supporting role, effectively reduce rollover stand to rock.
In order to make underframe 10 adapt to the power distribution cabinet of different length, the second end at underframe 10 is provided with telescopic extension frame 12, can adjust the entire length of underframe 10 by arranging Extension support 12 according to the power distribution cabinet of different length, meet different use needs.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
