Description

Pallet truck

Technical Field

The utility model belongs to building block brick preparation auxiliary assembly field, concretely relates to supporting plate transport vechicle for non-burning brick.

Background

The baking-free brick is a novel wall material which is manufactured by using materials such as fly ash, coal cinder, coal gangue, tailing slag, chemical slag or natural sand, tidal marsh mud and the like as main raw materials without high-temperature calcination, has the characteristics of high strength, light weight, heat preservation, sound insulation, environmental protection, no pollution and the like, and is widely applied in the industry of buildings.

In the process of pressing and curing, the stress distribution of the baking-free brick is difficult to avoid and has deviation in the forming process, the stress concentration part is easy to crack, and the baking-free brick can be ensured to have enough strength and hardness only by carrying out good maintenance. Therefore, during loading, unloading, transporting and even curing of the green bricks which are just pressed, collision should be reduced as much as possible, direct pouring and throwing are not allowed, otherwise, the appearance of the product is easy to damage, and the product becomes waste; the supporting plate is used as an essential supporting pad component in the manufacturing process of the baking-free brick, and can effectively ensure the placing and transportation stability of the baking-free brick in the manufacturing, processing and even placing processes.

Because the cement supporting plate feeding area at the feeding port of the existing small and medium-sized brick making machine depends on manual feeding before pressing, the supporting plate feeding operation of a green brick area can be completed by a material taking mode of a mechanical arm. Because the supporting plate at the feeding port of the brick making machine is mostly carried by manpower, the high weight of the cement supporting plate is often a big factor limiting the carrying efficiency; the single cement supporting plate has to be transported by two persons, so that the feeding speed of the supporting plate at the feeding port of the brick making machine severely limits the practical working efficiency; some manufacturers also consider adopting advanced machinery such as a forklift to carry the supporting plate in an auxiliary way, however, the forklift can be used for transporting the supporting plate from a warehouse or an external place into a factory building, and how to quickly, accurately and efficiently place the supporting plate transported to the door of the factory building at the feed inlet of the brick making machine in consideration of the compactness of the factory building space and the narrowness of the feed inlet of the brick making machine, which is a technical problem to be solved urgently by technical personnel in the field.

2) As a specific implementation scheme of the present invention, the clamping portion here is still preferably in a top-bottom mold clamping structure; the structure is characterized in that the bin promotion of the space of the factory building is considered, and the clamping part needs to be lifted and transported in the later period, so that the clamping part is designed into an upper and lower die assembly structure, the action directions of the same integral part are positioned in the height direction and cannot extend to two sides, and the purpose of effectively utilizing the space with higher height of the factory building is achieved; during actual operation, the rack can be pushed firstly, so that the supporting unit is lower than the placing surface of the supporting plate and penetrates through the lower part of the supporting plate, then the power source is started, the guide rod starts to move upwards along the door post, and due to the constraint relation between the supporting unit at the bottom of the guide rod and the bottom surface of the supporting plate, the supporting unit lifts the supporting plate to lift the supporting plate together with the supporting plate, and finally the transportation purpose is achieved; the upper plate surface of the supporting unit and the cross beam of the gantry-shaped portal frame also play a role in clamping the upper plate surface and the lower plate surface of the fixed supporting plate, and are favorable for ensuring and even improving the position stability of the stacked supporting plates during transportation.

3) In fact, for the supporting unit, the utility model achieves the purpose of containing and supporting the supporting plate by adopting the angle irons which are symmetrical to each other and have L-shaped cross sections; as for the design of the limiting section, the depth of the supporting plate inserted into the supporting unit is ensured, and the adverse effect on the normal transportation of the device caused by the shallow or deep insertion of the supporting plate is avoided.

4) The supporting unit is used as a supporting unit, two realization mechanisms are provided, one of the two realization mechanisms is a mode of directly adopting the inclined fixed welding or screw connection of the supporting unit and the bottom end of the guide rod, at the moment, an inclined dustpan shape similar to a front high thick bottom can be formed according to a containing area formed by the supporting unit, and the front end of the supporting unit is smoothly inserted below a flatly placed supporting plate in parallel through an inclined rack during transportation, after the supporting unit lifts the supporting plate to be in contact with a portal-shaped door frame, the supporting plate is obliquely arranged on a transportation trolley, and due to the limiting effect of a limiting section, the self gravity of the supporting unit ensures the placing stability of the supporting unit; the other scheme is that the support unit and the guide rod are in hinged fit, the fit structure has the advantages that after the support unit and the gantry portal clamp the support plate, the transportation stability of the support plate is guaranteed, and the two support sections forming the support unit cannot be completely symmetrical or parallel to each other due to height or angle errors existing in design, installation and even assembly.

5) The above description, considering the use cost and the structure simplification factor, the power source here is the jack, and for the convenience of operation, the utility model arranges the turning handle at the jack, and makes the turning handle extend forward and form the rotation fit with the vertical rod; in other words, the rotating handle, the vertical rods for fixing the two ends of the rotating handle and the jack form a structure similar to a simple supported beam, so that on one hand, the rotating handle is utilized to realize the convenient driving effect on the jack, and on the other hand, the structural stability of the rotating handle is ensured by the simple supported beam structure; the arrangement direction of the upright stanchion is based on the operation end of a worker positioned at the front end of the rack, so that the upright stanchion is convenient to operate in due time. As for the stable structure of the upright stanchion, the upright stanchion is realized by connecting a gantry portal and/or a frame, so that a triangular support or a multi-angle stable support effect is formed.

6) As the utility model discloses, all the time to attribute to on the travelling bogie, the overall arrangement of wheel makes the specified removal purpose that the frame possessed more. Due to the design of the handle, the manual pushing effect of the rack is realized; the design of supporting part has guaranteed especially that when the dolly does not use or when it is placed on one side, can effectively guarantee the holistic stability of placing of frame, and its simple structure and practicality.
