Description

Technical Field:

[0001] The utility model relates to the technical field of hydraulic loading machines, in particular to a weighing hydraulic tipping loading machine. Background Art:

[0002] When a container transport vehicle is loading goods, it sometimes needs to be lifted for loading, such as when transporting PVC particles. In the prior art, a hydraulic unloading machine is generally modified into a hydraulic loading machine with the main difference being that the direction of the vehicle head is opposite. Although the existing hydraulic loading machine realizes the lifting and loading of the container transport vehicle, with the popularization and application, some deep-seated technical problems have been found, mainly reflected in two aspects. One is that most of the turning force points of the existing hydraulic loading machine are located in the middle of the entire tipping plate or near the turning axis, while the overall center of gravity of the container and the transport vehicle is located in the middle and rear, resulting in an upward tilting force on the front end, which not only accelerates the wear of the rotating support but also poses a risk of welding open. Another relatively prominent problem is the low weighing accuracy. In order to accurately measure the loading weight, a weighing sensor is usually installed on the platform of the existing hydraulic loading machine, and then the weighing sensor measures the weight of the tipping plate and the goods on it. Although this method can achieve weighing measurement, since the hydraulic station is installed on the platform rather than on the tipping plate, there is hydraulic oil in the oil cylinder when the tipping plate is lifted, and the hydraulic oil in the oil cylinder returns to the hydraulic station when the tipping plate is laid flat, resulting in a large error in the weighing measurement result. Therefore, it is necessary to improve and optimize on the basis of the existing hydraulic loading machine.

[0003] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Content of the Utility Model:

[0004] The purpose of the utility model is to solve the problems existing in the prior art, and provide a weighing hydraulic tipping loading machine, which has the advantages of reasonable structure design, safer and more reliable turning, high weighing accuracy, etc.

[0005] The utility model realizes the above purpose by adopting the following technical solutions:

[0006] The weighing hydraulic tipping loading machine includes a foundation, multiple embedded plates are arranged on the foundation at intervals, weighing sensors are arranged on the embedded plates, a platform is arranged at the upper end of the weighing sensors, a rotating support is arranged at the front end of the platform, a tipping plate is rotatably arranged on the rotating support, turning brackets are respectively arranged on both sides of the tipping plate, the distance from the turning bracket to the front end of the tipping plate is greater than the distance to the rear end of the tipping plate, an upper support is arranged on the turning bracket, a lower support corresponding to the platform is arranged on the platform, a turning oil cylinder is rotatably arranged on the lower support, the upper end of the turning oil cylinder is rotatably connected with the upper support, the turning oil cylinder is connected with a hydraulic station through an oil circuit, and the hydraulic station is arranged on the platform.

[0007] The distance from the upper support to the front end of the tipping plate is greater than the distance from the lower support to the front end of the tipping plate.

[0008] Four wheel stoppers are arranged at intervals on the tipping plate, and corresponding avoidance grooves are arranged on the foundation.

[0009] A limiting mechanism for limiting the front end of the container is arranged on the tipping plate. The limiting mechanism includes bases arranged on both sides of the tipping plate. An elevating oil cylinder is vertically arranged at the upper end of the base. A limiter is arranged between the two elevating oil cylinders, and the limiter acts on the container for limiting.

[0010] The utility model adopts the above structure, and can bring the following beneficial effects:

(3) By designing the tipping plate support on one side close to the rear end of the tipping plate, the center of gravity of the tipping plate and its components falls between the tipping support and the front end of the tipping plate, thereby effectively preventing the front end of the tipping plate from tilting up, and the tipping of the tipping plate is more stable, safe and reliable. (4) By arranging the tipping oil cylinder obliquely backward, in addition to meeting the tipping drive requirement, the stroke of the tipping oil cylinder can be effectively shortened.

Detailed implementation mode:

[0018] In order to more clearly illustrate the overall concept of the present utility model, the following will be described in detail by way of examples in conjunction with the accompanying drawings of the specification.

[0019] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present utility model is not limited by the specific embodiments disclosed below.

[0020] Each embodiment in this specification is described in a progressive manner. The same or similar parts among the embodiments can be referred to each other, and the differences between each embodiment and other embodiments are emphasized.

[0021] In addition, terms such as "front end", "back end", "upper", "lower", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the position of the indicated technical features.

[0022] In the present utility model, unless otherwise clearly defined and limited, terms such as "provided with", "set", "connected", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection; it may be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0023] Such as Figures 1-5As shown in the figure, the weighing type hydraulic tipping loader includes a foundation 1. A plurality of embedded plates 2 are arranged on the foundation 1 at intervals. A weighing sensor 3 is arranged on the embedded plate 2. A platform 4 is arranged at the upper end of the weighing sensor 3. A rotary support 5 is arranged at the front end of the platform 4. A tipping plate 6 is rotatably arranged on the rotary support 5. Turning brackets 7 are respectively arranged on both sides of the tipping plate 6. The distance from the turning bracket 7 to the front end of the tipping plate 6 is greater than the distance to the rear end of the tipping plate 6. An upper support 8 is arranged on the turning bracket 7. A corresponding lower support 9 is arranged on the platform 4. A tipping cylinder 10 is rotatably arranged on the lower support 9. The upper end of the tipping cylinder 10 is rotatably connected to the upper support 8. The tipping cylinder 10 is connected to a hydraulic station 11 through an oil circuit. The hydraulic station 11 is arranged on the platform 4. By directly designing the embedded plate 2 on the foundation 1 to replace the traditional pit type structure, the construction is more convenient and fast. In practical applications, the number of the embedded plates 2 is 4 or 6, and the two side embedded plates 2 are symmetrically designed. The weighing sensor 3 is arranged on the embedded plate 2, and the platform 4 is installed on the weighing sensor 3 to weigh the entire platform 4 and the components thereon, effectively eliminating the measurement error of the hydraulic oil and making the weighing measurement more accurate. By designing the turning bracket 7 on one side close to the rear end of the tipping plate 6, the center of gravity of the tipping plate 6 and the components thereon falls between the turning bracket 7 and the front end of the tipping plate 6, thereby effectively preventing the front end of the tipping plate 6 from tilting up, and the tipping of the tipping plate 6 is more stable, safe and reliable. (4) By arranging the tipping cylinder obliquely backward, in addition to meeting the tipping drive requirement, the stroke of the tipping cylinder can be effectively shortened.

[0024] The distance from the upper support 8 to the front end of the tipping plate 6 is greater than the distance from the lower support 9 to the front end of the tipping plate 6. This design realizes the backward inclination design of the tipping cylinder 10, which can effectively shorten the stroke of the tipping cylinder 10. Especially, the three-stage cylinder can be shortened to a two-stage cylinder, which can significantly reduce the cost and improve the service life of the cylinder. The reason why the inclined design can be adopted in this article is that when loading and tipping, that is, when tipping, there is no cargo in the container 16 on the transport vehicle 15, so the tipping is relatively easy.

[0025] Four wheel stoppers 12 are arranged on the tipping plate 6 at intervals. A corresponding avoidance groove 13 is arranged on the foundation 1. The wheel stopper 12 belongs to the prior art and has a wide application in the hydraulic unloader, and can be directly applied to realize the wheel limit.

[0026] A limiting mechanism 14 for limiting the front end of the container 16 is provided on the flap 6. The limiting mechanism 14 includes bases 1401 arranged on both sides of the flap 6. A lifting oil cylinder 1402 is vertically arranged at the upper end of the base 1401. The purpose of designing the lifting oil cylinder 1402 is to facilitate the passage of the transport vehicle. A limiter 1403 is arranged between the two lifting oil cylinders 1402. The limiter 1403 acts on the container 16 for limiting. Since the container 16 is inclined after flipping, the limiting mechanism 14 can limit the container 16.

[0027] The above specific implementation manners cannot be used as a limitation to the protection scope of the present invention. For those skilled in the art of this technology, any alternative improvement or transformation made to the implementation manners of the present invention falls within the protection scope of the present invention.

[0028] Where the present invention is not described in detail, it is the well-known technology of those skilled in the art of this technology.
