Description
Technical Field
The utility model belongs to the technical field of equipment work piece transport, concretely relates to hand push flatbed with stride across obstacle.
Background
In the process of transferring and transporting equipment or workpieces, obstacles (such as doorsills with anti-theft doors, paved water and electric pipelines, steps and the like) which are difficult to remove or cannot be removed are inevitably encountered, the existing hand-pushed flat car can only run on an unobstructed road and is difficult to cross the obstacles, and great difficulty is brought to the transferring and transporting of the equipment or the workpieces. Therefore, it is an urgent need to solve the problem of designing a hand-pushed flat car for transporting workpieces which can cross obstacles.
Disclosure of Invention
The utility model discloses an overcome the problem that prior art exists, provide a rational in infrastructure simple, the high hand push flatbed that has the obstacle crossing function of security, can realize strideing across the obstacle and transport.
The utility model discloses realize above-mentioned purpose's technical scheme is:
the utility model provides a hand push flatbed with stride across obstacle function which characterized by, its structure is: two ends of the flat car are respectively provided with a lifting travelling mechanism; the flatbed includes: the lower part of the flat frame is connected with a walking universal wheel and a walking fixed wheel; the lifting traveling mechanism comprises: the rotating part is connected with a lifting mechanism, the rotating part is provided with a rotary fixed lock catch, the lifting mechanism is connected with a handle rocker, and the bottom end of the lifting mechanism is provided with a lifting travelling wheel; and two ends of the flat plate frame respectively lift the rotating parts of the traveling mechanism.
The utility model has the advantages that: the utility model discloses a twist grip rocker for the platform truck carries out elevating movement on the vertical direction. When crossing over the barrier, the platform truck frame, the walking universal wheels at the bottom end of the platform truck frame and the walking fixed wheels can be lifted to a certain height d (d > b, b is the height of the barrier) on the ground, and finally the purpose of crossing over the barrier to transfer and transport is achieved.
The rotating parts on the front side and the rear side of the flat car frame enable the lifting mechanism and the lifting travelling wheels to be parallel to the ground, and normal use of the flat car is not affected when no barrier exists.
The utility model has the advantages of reasonable and simple structure, high safety, convenient transportation and the like.

In fig. 1: 1. flat car: 1-1 parts of a flat plate frame, 1-2 parts of a walking universal wheel, 1-3 parts of a walking directional wheel; 2. lifting and traveling mechanism: 2-1, a lifting mechanism, 2-2, a handle rocker, 2-3, a rotary fixed lock catch, 2-4, a lifting travelling wheel, 2-5 and a rotating part; 3. an obstacle.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, a hand-pushed flat car having a function of crossing obstacles includes a flat car 1 and a lifting and lowering traveling mechanism 2. The flat car 1 includes: the lower part of the platform frame 1-1 is connected with a walking universal wheel 1-2 and a walking fixed wheel 1-3. The lifting and traveling mechanism 2 includes: the rotating part 2-5 is connected with the lifting mechanism 2-1, the rotating part 2-5 is provided with a rotary fixed lock catch 2-3, the lifting mechanism 2-1 is connected with a handle rocker 2-2, and the bottom end of the lifting mechanism 2-1 is provided with a lifting travelling wheel 2-4. Two ends of the flat car frame 1-1 are respectively connected with the rotating parts 2-5 of the lifting travelling mechanism 2 through bolts.
As shown in fig. 2-4, the specific working process of the present invention is as follows: when the hand-push flat car with the obstacle crossing function is used for crossing an obstacle 3, firstly, the minimum distance c between the lifting walking wheels 2-4 and the walking universal wheels 1-2 is ensured to be larger than the length a of the obstacle 3.
As shown in figure 2, before crossing the obstacle 3, the rotary fixed lock catch 2-3 is pulled out, the rotary part 2-5 is turned by 90 degrees to enable the lifting mechanism 2-1 to be vertical to the ground, and then the rotary fixed lock catch 2-3 is inserted into the connecting hole of the rotary part 2-5 to be mechanically locked.
When crossing the obstacle 3, as shown in fig. 3, the platform truck 1 is lifted by rotating the handle rocker 2-2, so that the walking universal wheels 1-2 and the walking fixed wheels 1-3 at the bottom end of the platform truck frame 1-1 can be lifted to a certain height d from the ground, as shown in fig. 1, and the height d is ensured to be higher than the height b of the obstacle 3 itself until the obstacle 3 is completely crossed, as shown in fig. 4. And finally, pulling out the rotary fixed lock catch 2-3 again, and turning the rotary part 2-5 for 90 degrees to enable the lifting mechanism 2-1 to be parallel to the ground, so that the aim of transferring and transporting the workpieces by the flat car 1 across the barrier 3 is fulfilled.
