Description

Technical Field

[0001] This utility model belongs to the field of construction equipment technology, specifically relating to a steel pipe handling and collection vehicle for construction sites. Background Technology

[0002] Steel pipes for construction are one of the most commonly used infrastructure materials on construction sites. They can be classified into seamless steel pipes and welded steel pipes, depending on whether they have welds or not. Welded steel pipes are further divided into spiral steel pipes and straight seam steel pipes based on the type of weld. Both are widely used in building piling, structures, steel structures, load-bearing, and drainage.

[0003] Chinese Patent Application No. CN202220222848.9 discloses a steel pipe handling and collection vehicle for construction sites. Addressing the problem that existing steel pipe collection methods often involve simply placing them directly into the collection vehicle, resulting in scattered, wobbly piles that are prone to falling, this invention proposes the following solution: It includes a base with four symmetrically arranged wheels rotatably connected to its bottom. A box is fixedly installed on the top of the base, with openings on its top and one side. Two symmetrically arranged fixing columns are fixedly installed on the inner bottom wall of the box, each with sliding holes. A dual-axis motor is fixedly installed on the inner bottom wall of one of the sliding holes, and screws are rotatably connected to the inner walls of both sliding holes. This invention is simple to operate and convenient to use, facilitating the secure placement of steel pipes and allowing for neat shaking during placement, thus aiding in transportation.

[0004] Regarding the aforementioned related technologies, the inventors have discovered at least the following problems: the material handling and collection vehicle is not convenient for manual unloading, and unloading requires manual handling, which increases the labor intensity of workers. Therefore, we provide a construction site steel pipe handling and collection vehicle that facilitates material unloading. Utility Model Content

[0025] Please see Figure 1-7 This utility model provides a steel pipe transport and collection vehicle for construction sites, including a base 1, a collection box 8 at the upper end of the base 1, a second fixed seat 101 fixedly installed at the upper end of the base 1, a first fixed seat 87 fixedly connected to the lower end of the collection box 8, and a second cylinder 9 between the first fixed seat 87 and the second fixed seat 101. A second telescopic rod 91 is movably installed at the front end of the second cylinder 9, and the end of the second cylinder 9 and the end of the second telescopic rod 91 are respectively rotated with the second fixed seat 101 and the first fixed seat 87. A rotating seat 102 is fixedly installed on the side of the base 1 away from the second fixed seat 101, and a rotating shaft 1021 is rotatably installed inside the rotating seat 102. A connecting piece 88 is fixedly connected to the outside of the rotating shaft 1021, and the other end of the connecting piece 88 is fixedly connected to the bottom of the collection box 8. A fixing plate 2 is fixedly installed at the upper end of the base 1, and a control switch 3 is fixedly installed on the surface of the fixing plate 2.

[0026] By adopting the above technical solution: during unloading, the second cylinder 9 drives the second telescopic rod 91 to extend, and pushes one side of the collection box 8 to rise through the first fixed seat 87. Furthermore, the ends of the second cylinder 9 and the second telescopic rod 91 are respectively adjusted in angle through the second fixed seat 101 and the first fixed seat 87. At the same time, the other side of the collection box 8 is connected to the rotating shaft 1021 in the rotating seat 102 through the connector 88, which can make the collection box 8 tilt and allow the steel pipe inside the collection box 8 to slide out.

[0027] In this embodiment, a first telescopic rod 85 is fixedly installed on one side inside the collection box 8, and a pusher plate 86 is fixedly connected to the end of the first telescopic rod 85. A first cylinder 84 for driving the first telescopic rod 85 is fixedly installed on the outside of the collection box 8. By setting the first telescopic rod 85 and the pusher plate 86, when the steel pipe slides out of the collection box 8, the first cylinder 84 drives the first telescopic rod 85 to push the pusher plate 86 to move, so that the steel pipe can slide out of the collection box 8 quickly.

[0028] In this embodiment, a plurality of rollers 83 are rotatably arranged inside the bottom surface of the collection box 8; by setting the rollers 83, the steel pipe slides more smoothly when it slides out of the collection box 8.

[0029] In this embodiment, a housing 5 is fixedly installed at the lower end of the base 1. A motor 51 and a differential 52 are fixedly installed inside the housing 5, and the output end of the motor 51 is fixedly connected to the differential 52. Rollers 7 are connected to both sides of the differential 52 through transmission rods 6. A caster 4 is movably installed on the lower end of the base 1 away from the housing 5. By setting up the differential 52, the caster 7 and the caster 4, the base 1 can be moved by the motor 51 cooperating with the differential 52 to drive the caster 7 to rotate, thereby reducing the pushing force required by the workers when transporting steel pipes. At the same time, the direction of movement of the base 1 can be adjusted by the caster 4, and the caster 7 can be easily turned by the differential 52.

[0030] In this embodiment, an electric push rod 81 is movably installed on the inner side of the inner wall of the collection box 8, and a pressure plate 82 is fixedly connected to the upper end of the electric push rod 81. By setting the electric push rod 81 and the pressure plate 82, the steel pipe is placed in the collection box 8, and then the pressure plate 82 is pulled down by the electric push rod 81 to apply pressure to the steel pipe, so that the steel pipe is stably placed in the collection box 8.

[0031] The working principle and usage process of this utility model are as follows: During use, the steel pipe is placed in the collection box 8. Then, the electric actuator 81 pulls the pressure plate 82 downwards, applying pressure to the steel pipe and ensuring it remains stably within the collection box 8. The motor 51, in conjunction with the differential 52, drives the rollers 7 to rotate, thus moving the base 1 and reducing the pushing force required by workers during pipe transport. Simultaneously, the casters 4 allow adjustment of the base 1's direction of movement, and the differential 52 facilitates turning of the rollers 7. During unloading, the second cylinder 9 drives the second telescopic rod 91 to extend, pushing one side of the collection box 8 upwards via the first fixed seat 87. Furthermore, the ends of the second cylinder 9 and the second telescopic rod 91 are angled via the second fixed seat 101 and the first fixed seat 87, respectively. Meanwhile, the other side of the collection box 8 is connected to the rotating shaft 1021 inside the rotating seat 102 via the connector 88, which allows the collection box 8 to tilt and the steel pipe inside the collection box 8 to slide out. In addition, the roller 83 makes the steel pipe slide more smoothly. During the unloading process of the steel pipe, the first cylinder 84 drives the first telescopic rod 85 to push the pusher plate 86 to move, which allows the steel pipe to slide out of the collection box 8 quickly, thus facilitating the workers to unload the material quickly without the need for manual handling and unloading, reducing the burden on the workers.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
