Technical Field
[0001] This utility model relates to the field of lifting platform technology, and in particular to a hydraulic lifting platform for cargo transport. Background Technology
[0002] A hydraulic lifting platform is a mechanical device that uses hydraulic transmission technology to achieve vertical lifting. It mainly consists of a load-bearing platform, hydraulic cylinders, a pump station, and a control system. Its working principle is that a motor drives a hydraulic pump, which pressurizes hydraulic oil into the hydraulic cylinders, pushing the piston rod to extend and retract, thereby smoothly raising and lowering the platform. This equipment features a stable structure, high load-bearing capacity, and smooth lifting, and is widely used in factories, warehouses, logistics centers, and other scenarios for loading and unloading goods, equipment maintenance, and high-altitude operations.
[0003] In the prior art, such as Chinese Patent No. CN210764135U, a multi-functional hydraulic lifting platform belongs to the field of lifting equipment technology. It includes a loading platform and a base plate. The loading platform is located on the upper part of the base plate, and the loading platform and the base plate are connected by two sets of support components. A hydraulic push rod is provided above the base plate to drive the support components for lifting. A cavity is provided on the upper part of the loading platform, and a discharge plate is provided inside the cavity. Several rollers are rotatably arranged on the upper part of the discharge plate, and the bottom of the discharge plate is connected to the base plate through a multi-section telescopic rod. In this embodiment of the invention, through the arrangement of the discharge plate, rollers, and telescopic rod, the goods can be pushed towards the edge of the loading platform during unloading. Combined with a pull-out first plate and a second plate hinged to the first plate, the first plate can tilt between the loading platform and the ground to support the goods sliding towards the edge of the loading platform. This has the advantages of safe unloading, labor-saving, and low unloading cost.
[0004] While the above-mentioned solution has the advantages mentioned above, its disadvantages are as follows: Although it can push the goods to the edge of the loading platform during unloading by setting up unloading plates, rollers, and telescopic rods, and with the pull-out first plate and the second plate hinged to the first plate, the first plate can tilt between the loading platform and the ground to support the goods sliding towards the edge of the loading platform, which has the advantages of safe unloading, labor saving, and low unloading cost, the loading platform is raised and lowered by a scissor-like mechanism, so that the loading platform is still a certain height from the ground when it is lowered to the lowest point. When it is necessary to move the goods on the ground to the loading platform, it is time-consuming and laborious, thus increasing the labor intensity of the workers. Utility Model Content
[0005] The purpose of this invention is to address the problem in existing technologies where, although the unloading platform, rollers, and telescopic rods can push goods towards the edge of the loading platform during unloading, and the pull-out first plate and the second plate hinged to the first plate allow the first plate to tilt between the loading platform and the ground to support the goods sliding towards the edge of the loading platform, offering advantages such as safe unloading, labor-saving, and low unloading costs, the loading platform is raised and lowered using a scissor-like mechanism. Even at its lowest point, the loading platform is still a certain height above the ground, making it time-consuming and labor-intensive to move goods from the ground to the loading platform, thus increasing the workload of workers.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a hydraulic lifting platform for cargo transport, comprising: a hydraulic lifting platform body, and further comprising:
[0007] Two fixed blocks are symmetrically fixedly connected to one side of the hydraulic lifting platform body near the bottom. A round rod is fixedly connected to the opposite side of the two fixed blocks. Two movable strips are symmetrically rotatably connected to the outer surface of the round rod. A sliding plate is slidably connected inside the two movable strips. A convex groove is opened on one side of the sliding plate. A movable frame is slidably connected to the inner wall of the convex groove. A placement frame is fixedly connected to one side of the movable frame. A rack is fixedly connected to one side of the movable strip. A rotating rod is rotatably connected to the opposite side of the sliding plate. Gears are fixedly connected to both ends of the rotating rod. The gears mesh with the rack. A winding wheel is fixedly connected to the outer surface of the rotating rod. A pull rope is fixedly wound around the outer surface of the winding wheel. A fixed rod is fixedly connected to the opposite side of the placement frame. The fixed rod is fixedly connected to the pull rope.
[0008] Preferably, a guide rod is fixedly connected to one side of the inner wall of one of the movable strips, and the guide rod is slidably connected to the slide plate.
[0009] Preferably, a lead screw is rotatably connected to the opposite side of the inner wall of another movable strip, and the lead screw is threadedly connected to the slide plate.
[0010] Preferably, a motor is fixedly connected to the bottom of another movable bar, and the output end of the motor is fixedly connected to one end of a lead screw.
[0011] Preferably, a second fixing block is fixedly connected to the other side of the movable strip, and a second round rod is fixedly connected to the opposite side of the two second fixing blocks. Two electric telescopic rods are symmetrically rotatably connected to the outer surface of the second round rod.
[0012] Preferably, two U-shaped blocks are symmetrically fixedly connected to one side of the hydraulic lifting platform body near the bottom, and a round rod three is fixedly connected to the opposite side of the two arms of the U-shaped blocks, and the electric telescopic rod is rotatably connected to the round rod three.
[0013] Preferably, a protective frame is fixedly connected to the top of the hydraulic lifting platform body.
[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0015] 1. This utility model uses a controller to start the motor, causing its output shaft to drive the lead screw to rotate. Then, under the action of the threaded connection between the lead screw and the sliding plate, and with the cooperation of the guide rod limiting and guiding the sliding plate, the sliding plate can move upward along the outer surface of the lead screw, simultaneously driving the placement frame and gears upward. Next, under the meshing action of the gear and rack, the gear can rotate, simultaneously driving the rotating rod and the winding wheel to rotate, winding the pull rope. Through the winding of the pull rope, a pulling force is applied to the fixed rod, causing the movable frame to slide upward along the inside of the convex groove, simultaneously driving the placement frame upward, moving it to the position above the movable bar, lifting the goods above the hydraulic lifting platform body. At this point, workers can easily place goods above the hydraulic lifting platform body, making it easy to move goods from the ground to the hydraulic lifting platform body, saving time and effort, and reducing the labor intensity of workers.
[0016] 2. This utility model uses a controller to control the retraction of the electric telescopic rod, which can apply a pulling force to the second round rod, the second fixed block, and the movable bar, causing the movable bar to rotate downwards at an appropriate angle around the outer surface of the first round rod, keeping the movable bar, movable frame, and placement frame in a vertical state for easy storage. Conversely, it can keep the movable bar, movable frame, and placement frame at a certain tilt angle for easy loading and unloading of goods, thus improving the ease of use of this device.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0025] Examples, such as Figure 1-4 As shown, this utility model provides a hydraulic lifting platform for cargo transport, including: a hydraulic lifting platform body 1, and two fixed blocks 2, symmetrically fixedly connected to one side of the hydraulic lifting platform body 1 near the bottom. A round rod 201 is fixedly connected to the opposite side of the two fixed blocks 2. Two movable bars 202 are symmetrically rotatably connected to the outer surface of the round rod 201. A sliding plate 302 is slidably connected inside the two movable bars 202. A convex groove is provided on one side of the sliding plate 302, and a movable frame 303 is slidably connected to the inner wall of the convex groove. A placement frame 304 is fixedly connected to one side of the movable frame 303, a rack 3 is fixedly connected to one side of the movable bar 202, a rotating rod 307 is rotatably connected to the opposite side of the slide plate 302, gears 301 are fixedly connected to both ends of the rotating rod 307, the gears 301 mesh with the rack 3, a winding wheel 308 is fixedly connected to the outer surface of the rotating rod 307, a pull rope 306 is fixedly wound around the outer surface of the winding wheel 308, a fixing rod 305 is fixedly connected to the opposite side of the placement frame 304, and the fixing rod 305 is fixedly connected to the pull rope 306.
[0026] Furthermore, such as Figure 1-4As shown, a guide rod 311 is fixedly connected to the opposite side of the inner wall of one of the movable strips 202. The guide rod 311 is slidably connected to the slide plate 302. With the above arrangement, the slide plate 302 can slide along the outer surface of the guide rod 311.
[0027] Furthermore, such as Figure 1-4 As shown, a lead screw 310 is rotatably connected to the opposite side of the inner wall of another movable strip 202. The lead screw 310 is threadedly connected to the slide plate 302. With the above arrangement, when the lead screw 310 rotates, the slide plate 302 can move to one side along the outer surface of the lead screw 310.
[0028] Furthermore, such as Figure 1-4 As shown, a motor 309 is fixedly connected to the bottom of another movable bar 202. The output end of the motor 309 is fixedly connected to one end of the lead screw 310. The motor 309 is started by the controller, so that its output shaft drives the lead screw 310 to rotate.
[0029] Furthermore, such as Figure 1-4 As shown, a fixing block 203 is fixedly connected to the other side of the movable bar 202. A round rod 204 is fixedly connected to the opposite side of the two fixing blocks 203. Two electric telescopic rods 205 are symmetrically rotatably connected to the outer surface of the round rod 204. With the above arrangement, when the electric telescopic rod 205 extends or retracts, a force can be applied to the round rod 204, causing the electric telescopic rod 205 to rotate around the round rod 204 at an appropriate angle.
[0030] Furthermore, such as Figure 1-4 As shown, two U-shaped blocks 206 are symmetrically fixedly connected to one side of the hydraulic lifting platform body 1 near the bottom. Round rods 207 are fixedly connected to the opposite side of the two arms of the U-shaped blocks 206. The electric telescopic rod 205 is rotatably connected to the round rods 207. With the above arrangement, when the electric telescopic rod 205 extends or retracts, a force can be applied to the round rods 207, causing the electric telescopic rod 205 to rotate around the round rods 207 at an appropriate angle.
[0031] Furthermore, such as Figure 1-4 As shown, a protective frame 101 is fixedly connected to the top of the hydraulic lifting platform body 1. The protective frame 101 provides a certain degree of protection.
[0032] Working Principle: During use, when the hydraulic lifting platform body 1 is raised to its lowest height (since the hydraulic lifting platform body 1 is existing technology, it will not be described in detail), the placement frame 304 is flush with the ground, and goods can be placed in the placement frame 304. Then, the controller controls the motor 309 to start, causing its output shaft to drive the lead screw 310 to rotate. Then, under the action of the threaded connection between the lead screw 310 and the slide plate 302, and with the cooperation of the guide rod 311 limiting and guiding the slide plate 302, the slide plate 302 can move upward along the outer surface of the lead screw 310, synchronously driving the placement frame 304 and gear 301 to move upward. Then, under the action of the meshing of the gear 301 and the rack 3, the gear 301 can rotate, synchronously driving the rotating rod 307 and the winding wheel 308 to rotate, winding the pull rope 306. Through the winding of the pull rope 306, a pulling force can be applied to the fixed rod 305, causing the movable frame 303 to slide upward along the inside of the convex groove. The device simultaneously moves the placement frame 304 upwards, positioning it above the movable bar 202. This lifts the goods above the hydraulic lifting platform body 1, allowing workers to easily place them on top. This facilitates the easy transfer of goods from the ground to the hydraulic lifting platform body 1, saving time and effort and reducing worker workload. The controller controls the retraction of the electric telescopic rod 205, applying tension to the second round rod 204, the second fixed block 203, and the movable bar 202. This causes the movable bar 202 to rotate downwards at an appropriate angle around the outer surface of the first round rod 201, keeping the movable bar 202, movable frame 303, and placement frame 304 vertical for easy storage. Conversely, it allows the movable bar 202, movable frame 303, and placement frame 304 to maintain a certain tilt angle for easy loading and unloading of goods, thus improving the ease of use of the device.
[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
