In the small handcart transport article in-process, with the help of the static friction force of antislip strip to the article, can prevent that the small handcart from the thing face landing of carrying when the state slope of standing, conveniently makes the article break away from ground, avoids the article to collide with ground, and convenient haulage, the utility model discloses rational in infrastructure, the material resources of using manpower sparingly can wide application in small handcart technical field.
Description
Technical Field
The utility model relates to a small handcart technical field, in particular to small handcart that laboratory was used.
Background
With the high precision requirement of laboratories on articles, ordinary forklifts and flat cars cannot meet the carrying work of high precision and heavy articles in laboratories. Such as: when carrying 100 ~ 150 kg's concrete test block, manual transport is very difficult, causes the damage easily moreover in handling, and then influences the experimental result, causes the serious loss of manpower and materials.
SUMMERY OF THE UTILITY MODEL
For solving above-mentioned technical problem, conveniently carry the article, avoid damaging the article, the utility model provides a small handcart that laboratory was used, the technical scheme who adopts as follows:
the utility model provides a small handcart that laboratory was used includes the backup pad, and the leading flank of backup pad is for carrying the thing face, carries the thing face to have arranged a plurality of antislip strips, and two pull rods have been arranged to the trailing flank of backup pad, and two wheels have been arranged to the trailing flank of backup pad.
Furthermore, the bottom end of the pull rod is formed with an inclined surface.
Furthermore, the anti-slip strip is made of carborundum.
Further, the pull rod is a telescopic rod.
Furthermore, the supporting plate is fastened with the object through a binding belt.
Further, the two pull rods are respectively provided with a support rod.
Further, when the pull rod is erected, the wheel is separated from the ground.
Has the advantages that: in the small handcart transport article in-process, with the help of the static friction force of antislip strip to the article, can prevent that the small handcart from the thing face landing of carrying when the state slope of standing, conveniently makes the article break away from ground, avoids the article to collide with ground, and convenient haulage, the utility model discloses rational in infrastructure, the material resources of using manpower sparingly can wide application in small handcart technical field.

FIG. 1 is a view of the structure of the dolly when it is set up, wherein the upper side, lower side, front side and rear side in the following are all relative to the orientation of the dolly when it is set up;
figure 2 is a side view of the dolly when erected.
Detailed Description
The present invention will be further described with reference to fig. 1 to 2.
The utility model relates to a small handcart that laboratory was used, it includes backup pad 11, and two pull rods 12 have been arranged to the trailing flank of backup pad 11, and pull rod 12 is the telescopic link. Two wheels 13 are arranged on the rear side of the support plate 11, and the two wheels 13 are respectively arranged on the two pull rods 12. The small handcart has simple structure and small occupied space.
The front side of the supporting plate 11 is a carrying surface, and the carrying surface is provided with a plurality of anti-slip strips for increasing the friction force between the carrying surface and the object. The anti-slip strip is made of carborundum materials.
In some embodiments, after the object is placed on the supporting plate 11, the supporting plate 11 is fastened by the binding band, and the binding band is fixed to the supporting plate by the binding object. The binding band is a common structure, and is not described in detail.
An inclined surface 15 is formed at the bottom end of the pull rod 12, when the pull rod 12 is erected, the inclined angle of the inclined surface 15 relative to the horizontal plane is 45 degrees, and the trolley can be conveniently inclined from the erected state after an object is fixed.
It should be noted that when the pull rod 12 is erected, the wheel 13 is separated from the ground by the support of the bottom end of the pull rod 12, that is, the height of the center of the wheel 13 should be greater than the radius of the wheel 13. In the process of inclining the small handcart, due to the action of the supporting plate 11 and the binding belt, the object and the supporting plate 11 are inclined simultaneously, the small handcart and the goods can be inclined continuously before the wheels 13 contact the ground, so that the resultant force of the normal force vertical component and the friction force vertical component is provided for the object by the object carrying surface of the supporting plate 11, the lifting force is increased continuously, and then the object is lifted off the ground; meanwhile, before the wheels 13 contact the ground, the lower end of the supporting plate 11 and a part of the object are always in contact with the ground, and due to the action of the binding belt, the object is prevented from slipping or falling due to insufficient lifting force or unstable support in the tilting process. With the continuous inclination of the supporting plate 11 and the object, the lifting force is formed by the resultant force of the normal force vertical component and the friction force vertical component, so that the lifting force is continuously lifted, and the object can be lifted off the ground finally.
The two pull rods 12 are respectively provided with a support rod 14, and the two support rods 14 are used for supporting the trolley when the trolley is flatly placed.
The specific use of the dolly is as follows: the cart is erected, and the article is fastened to the carrying surface by the binding band, and the cart is tilted. Simple operation and labor and material conservation.
The bottom end of the pull rod 12 is designed to have an inclination angle, so that the rotating radius of the small trolley during the inclination is effectively reduced, and the force analysis shows that in the inclination process of the small trolley, the lifting force formed by the resultant force of the normal force vertical component and the friction force vertical component provided by the object carrying surface when the object is just inclined along with the support plate 11 is small, and at the moment, the object is easy to slide or slide from the object carrying surface, so that the rotating radius of the support plate 11 is reduced to reduce the initial sliding distance of the object, and a larger inclination angle is obtained, so that a larger lifting force is obtained.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
