Description

Technical Field

[0001] This utility model relates to the technical field of RGV power vehicle equipment, specifically a low-platform multi-stage lifting RGV power vehicle. Background Technology

[0002] Existing RGV motor vehicles have some limitations in their lifting function, affecting their application effectiveness in specific scenarios. Traditional RGV motor vehicles typically use a single-stage hydraulic cylinder for lifting operations. While this method can meet the lifting needs of goods to a certain extent, in low-platform application scenarios, the stroke of a single-stage hydraulic cylinder is limited, making it difficult to achieve long-distance lifting and thus restricting the scope of application of RGV motor vehicles. Extensive research has been conducted on this issue. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a low-platform multi-stage lifting RGV power vehicle that can achieve a multi-stage lifting function with a long stroke, uniform force distribution and stability.

[0004] This utility model is achieved through the following technical solution: A low-platform multi-stage lifting RGV power vehicle of this utility model includes an RGV power vehicle, wherein the RGV power vehicle is provided with a multi-stage lifting assembly, characterized in that the multi-stage lifting assembly includes an upper platform plate and an intermediate platform, the RGV power vehicle is provided with a first lifting structure that drives the intermediate platform to move up and down, and the intermediate platform is provided with a second lifting structure that drives the upper platform plate to move up and down.

[0005] In a further technical solution, when the upper platform plate moves to the lowest side, the upper surface of the upper platform plate is flush with the upper surface of the RGV power vehicle.

[0006] A further technical solution is that when the upper surface of the upper platform plate is flush with the upper surface of the RGV power vehicle, the intermediate platform retracts into the upper platform plate.

[0007] In a further technical solution, an inner cavity is provided at the bottom of the upper platform plate, and the middle platform moves into the inner cavity.

[0008] In a further technical solution, a vertical plate is fixedly installed in the RGV power vehicle, and a bottom plate is fixedly installed on the lower side of the intermediate platform. When the intermediate platform moves downward, the bottom plate abuts against the vertical plate.

[0009] A further technical solution includes a first lifting structure comprising a plurality of first hydraulic cylinders fixedly installed inside the RGV power vehicle, wherein each first hydraulic cylinder is provided with a telescopic first telescopic rod, and the first telescopic rod is fixedly connected to the intermediate platform.

[0010] In a further technical solution, four first hydraulic cylinders and two second hydraulic cylinders are provided, and the first hydraulic cylinders and two hydraulic cylinders are arranged in a trapezoidal shape.

[0011] A further technical solution includes a second lifting structure comprising a plurality of second hydraulic cylinders fixedly installed at the bottom of the intermediate platform, wherein each second hydraulic cylinder is provided with a telescopic second telescopic rod, and the second telescopic rod is fixedly connected to the upper platform plate.

[0012] In a further technical solution, the second hydraulic cylinder is disposed on one side of the first hydraulic cylinder, and the second hydraulic cylinder is offset from the first hydraulic cylinder.

[0013] In a further technical solution, the RGV power vehicle is equipped with a hydraulic pump station, which is connected to the second hydraulic cylinder and the first hydraulic cylinder.

[0014] The beneficial effects of this utility model are as follows: First, the multi-stage lifting assembly disperses the hydraulic cylinders with the same stroke into a first hydraulic cylinder and a second hydraulic cylinder. The first hydraulic cylinder lifts the second hydraulic cylinder and the intermediate platform, and the second hydraulic cylinder lifts the upper platform plate, thereby realizing the multi-stage lifting function of the low platform.

[0015] Second, by installing a vertical plate inside the RGV power vehicle and a bottom plate inside the intermediate platform, since the upper platform plate is used to place heavy objects, when the second hydraulic cylinder and the first hydraulic cylinder are in the retracted state, the bottom plate abuts against the upper surface of the vertical plate, and the upper platform plate abuts against the upper surface of the intermediate platform. Thus, the upper platform plate and the intermediate platform can be supported, thereby avoiding continuous load on the second hydraulic cylinder and the first hydraulic cylinder and improving the working life of the second hydraulic cylinder and the first hydraulic cylinder.

[0016] Third, by using a trapezoidal layout of the second hydraulic cylinder and the first hydraulic cylinder, and by having the second hydraulic cylinder and the first hydraulic cylinder be arranged in a cross manner, the force distribution range can be effectively dispersed, avoiding force concentration, and making the first hydraulic cylinder more stable when lifting the intermediate platform, the second hydraulic cylinder, the second telescopic rod and the upper platform plate.

Detailed Implementation

[0028] like Figures 1-9 As shown, this utility model will be described in detail. For ease of description, the directions mentioned below are defined as follows: the directions of up, down, left, right, front, and back mentioned below are the same as... Figure 1 The projection relationship of the RGV power vehicle is consistent in the up, down, left, right, front, and back directions. The present invention provides a low-platform multi-stage lifting RGV power vehicle, including an RGV power vehicle 11. The RGV power vehicle 11 is provided with a multi-stage lifting assembly. When the upper platform plate 12 moves to the lowest side, the upper end surface of the upper platform plate 12 is flush with the upper end surface of the RGV power vehicle 11. The multi-stage lifting assembly includes an upper platform plate 12 and an intermediate platform 17. The RGV power vehicle 11 is provided with a first lifting structure that drives the intermediate platform 17 to move up and down, and the intermediate platform 17 is provided with a second lifting structure that drives the upper platform plate 12 to move up and down.

[0029] Advantageously, when the upper surface of the upper platform plate 12 is flush with the upper surface of the RGV power vehicle 11, the intermediate platform 17 is retracted into the upper platform plate 12.

[0030] Advantageously, the upper platform plate 12 has an inner cavity 31 at its bottom. When the upper platform plate 12 overlaps with the middle platform 17, the middle platform 17 is located inside the inner cavity 31.

[0031] Advantageously, two upright plates 22 are fixedly installed in the middle position of the RGV power vehicle 11, and two bottom plates 21 are fixedly installed on the lower side of the middle position of the middle platform 17. When the middle platform 17 moves downward, the bottom plates 21 abut against the upright plates 22, and at this time the middle platform 17 moves to the lowest point on the lower side.

[0032] Beneficially, the bottom plates 21 on both sides are arranged in a mirror symmetrical manner.

[0033] Advantageously, the first lifting structure includes a plurality of first hydraulic cylinders 16 fixedly installed inside the RGV power vehicle 11, and each first hydraulic cylinder 16 is provided with a telescopic first telescopic rod 18, which is fixedly connected to the intermediate platform 17.

[0034] Advantageously, there are four first hydraulic cylinders 16, which are arranged in a trapezoidal shape, that is, the lines connecting the first hydraulic cylinders 16 form a trapezoid, and the first hydraulic cylinders 16 are located at the four corners of the trapezoidal lines.

[0035] Advantageously, the second lifting structure includes a plurality of second hydraulic cylinders 15 fixedly installed at the bottom of the intermediate platform 17, and the second hydraulic cylinders 15 are provided with telescopic second telescopic rods 13, which are fixedly connected to the upper platform plate 12.

[0036] Advantageously, the intermediate platform 17 is provided with a perforation 14. When the intermediate platform 17 enters the upper platform plate 12, the fixing plate at the top of the second telescopic rod 13 is provided in the inner cavity 31, so that the intermediate platform 17 is completely placed in the upper platform plate 12.

[0037] Advantageously, when the intermediate platform 17 enters the upper platform plate 12, the lower end surface of the intermediate platform 17 is flush with the lower end surface of the upper platform plate 12.

[0039] Advantageously, the second hydraulic cylinder 15 is located on one side of the first hydraulic cylinder 16. The second hydraulic cylinder 15 and the first hydraulic cylinder 16 are staggered. Compared with the traditional rectangular layout, the force can be effectively distributed and the force concentration can be avoided, making the first hydraulic cylinder 16 more stable when lifting the middle platform 17, the second hydraulic cylinder 15, the second telescopic rod 13 and the upper platform plate 12.

[0040] Advantageously, the RGV power vehicle 11 is equipped with a hydraulic pump station 19, which is connected to the second hydraulic cylinder 15 and the first hydraulic cylinder 16 to provide a power source for the second hydraulic cylinder 15 and the first hydraulic cylinder 16.

[0041] The RGV power vehicle 11 is equipped with a multi-stage lifting assembly, which enables the upper platform plate 12 to be lifted to a relatively long height while meeting the low platform height requirement of the RGV power vehicle 11.

[0042] When the multi-stage lifting assembly is in operation, the first hydraulic cylinder 16 and the second hydraulic cylinder 15 can work synchronously or asynchronously. When the first hydraulic cylinder 16 is working, it can lift the intermediate platform 17, the second hydraulic cylinder 15, the second telescopic rod 13 and the upper platform plate 12 upward. When the second hydraulic cylinder 15 is working, it can drive the second telescopic rod 13 to lift the upper platform plate 12 upward.

This enables the function of lifting the upper platform plate 12 with a long stroke in the low-platform RGV power vehicle 11.
