Description

Technical Field

[0001] The utility model relates to the technical field of construction site transportation, in particular to a simple transportation tool for construction sites. Background Technique

[0002] In construction sites, the construction areas are usually large, and various test blocks and sampling materials made on the construction site often need to be manually carried to designated storage locations such as standard curing rooms. There are problems such as untimely manual handling and low efficiency over long distances. If an electric tricycle is used to carry various test blocks or sampling materials, there are problems such as being easily detained by the traffic police.

[0003] The Chinese invention patent with the publication date of February 2, 2021 and the publication number of CN112298312A discloses a construction site transport vehicle convenient for unloading, specifically related to the technical field of construction transport vehicles, including a vehicle frame. A transport hopper is arranged on the top of the vehicle frame. One side of the bottom of the transport hopper is arranged as an inclined plane. A rotating bearing is fixedly arranged at one end of the vehicle frame. A rotating shaft is arranged at the bottom of the inclined plane of the transport hopper. The rotating shaft is movably connected with the rotating bearing. A discharging mechanism is arranged between the vehicle frame and the bottom of the transport hopper. The discharging mechanism includes a discharging port, which is opened at the top of the inclined plane of the transport hopper. A first fixing block and a positioning block are respectively fixedly arranged on both sides of the bottom of the discharging port. This invention performs opening and closing operations on the discharging port through a discharging baffle, pulls the discharging baffle to move by using a connecting cable, and then cooperates with a first return spring to perform restoration operations on the discharging baffle. The opening and closing of the discharging port are synchronized with the overturning of the transport hopper, which is convenient for the transport vehicle to be tilted at a small angle for use.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0025] As Figure 1 and Figure 2 shown, a simple transportation tool for construction sites described in Embodiment 1 of the present invention includes a main frame 1 and a lifting frame 5 that is liftably arranged on the main frame 1, so that the space of the transportation tool can be enlarged to load more test blocks or sampling materials, and when not loading larger or more items, it can be contracted for easy movement or storage. Universal wheels 6 are provided at the bottom of the main frame 1 for easy movement of the transportation tool; a rotating handle 3 is hinged on the lifting frame 5 or the main frame 1, so that the handle can be unfolded and extended for use, facilitating the towing of the trolley; when not in use, the handle can also be rotated and folded on the trolley.

[0026] Furthermore, as Figure 1 and Figure 2 shown, the main frame 1 includes four vertical first steel pipes arranged in a rectangle and angle steels connected between adjacent first steel pipes. There are four angle steels, and the four horizontally arranged angle steels connect the four vertically arranged first steel pipes in a rectangle to form a rectangular frame. In this embodiment, the angle steels are connected to the lower ends of the first steel pipes.

[0027] Furthermore, as Figure 2As shown, reinforcing bars 4 are connected between the oppositely arranged angle steels. In this embodiment, reinforcing bars 4 are connected between the angle steels on the long side of the rectangular frame body to support the test blocks or sampling materials placed on the inner wall of the transportation tool.

[0028] Furthermore, as Figure 1 shown, reinforcing bars 4 are connected between the lower parts of adjacent first steel pipes around the rectangular frame body.

There are a total of four pairs of spaced steel plates 8 around the rectangular frame body, and a gap is formed between each pair of steel plates 8. And a notch is cut on the side of the first steel pipe facing the steel plate 8 so that the gap formed by a pair of steel plates 8 communicates with the inner space of the first steel pipe.

[0030] Furthermore, the lifting frame body 5 includes four second steel pipes and connectors connected between the upper parts of adjacent second steel pipes. A small rectangular frame body is also formed by connecting the connectors and the four second steel pipes. The diameter or width of the four second steel pipes is smaller than that of the first steel pipe. The second steel pipes slide through the first steel pipes, and the connectors can be embedded in the gaps between the corresponding pair of steel plates 8, so that the whole lifting frame body 5 can descend, making the second steel pipes slide into the first steel pipes and the connectors embedded between the steel plates 8, or the whole lifting frame body 5 can rise, thereby expanding the loading space of the transportation tool.

[0031] Among them, the first steel pipe and / or the second steel pipe is a square steel pipe or a round steel pipe. In this embodiment, as Figure 2 shown, both the first steel pipe and the second steel pipe are round steel pipes, and the diameter of the second steel pipe is smaller than that of the first steel pipe. In another embodiment, both the first steel pipe and the second steel pipe are square steel pipes, and the width of the second steel pipe is smaller than that of the first steel pipe.

[0032] Furthermore, as Figure 1 shown, a bolt 7 is horizontally inserted through the first steel pipe, and a number of holes at different heights that can be inserted by the bolt 7 are provided on the second steel pipe. The bolt 7 passes through the first steel pipe and is inserted into the hole at the same time to fix the lifting frame body 5 on the main frame body 1.

[0033] Embodiment 3 is different from Embodiment 2 in that the connector includes a reinforcing bar 4 and / or a steel pipe. In this embodiment, the connector includes a reinforcing bar 4 and a steel member. The steel member is a small steel pipe or an angle steel, and it is connected to the tops of adjacent second steel pipes around the small rectangular frame body. As Figure 1 shown, the reinforcing bar 4 is arranged below the steel member, and the reinforcing bar 4 is connected to the position near the top of adjacent second steel pipes.

[0034] Embodiment 4 is different from Embodiment 1 in that, asFigure 1 As shown, a pair of rotatable sleeves 2 spaced apart are provided at one end of the top of the lifting frame 5. The end of the rotating handle 3 is provided with a connecting shaft, and both ends of the connecting shaft penetrate into the rotatable sleeves 2 and are rotatably engaged with the rotatable sleeves 2, so that the rotating handle 3 is hinged at one end of the top of the lifting frame 5.
