Description

Technical Field

[0001] This utility model relates to the field of material handling equipment technology, specifically to a portable hydraulic material handling vehicle. Background Technology

[0002] In industrial production, pallet trucks are needed to transport semi-finished products, finished products, or bulk materials. Existing pallet trucks are limited to this purpose, requiring manual labor or other equipment for loading and unloading. Manual loading and unloading is time-consuming, labor-intensive, costly, and inefficient. Furthermore, using other equipment increases equipment and personnel costs. The existing pallet truck beds cannot be raised or lowered. When materials need to be raised to a certain height for loading equipment on the production floor, separate lifting equipment is required, further increasing production costs and making operation cumbersome. Utility Model Content

[0003] This utility model proposes a portable hydraulic pallet truck, which effectively solves the problems of existing pallet trucks that cannot be raised or lowered, have limited functions, and cannot meet the needs of various work scenarios.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A portable hydraulic pallet truck, characterized in that it includes a support platform, outriggers, a front support, a rear support, a sliding track, and a hydraulic lifting device. The outriggers include a first leg and a second leg. The front and rear supports are connected and fixed via the sliding track. A mounting base is provided on the front support. A groove is formed on the side wall of the sliding track. One end of the first leg is movably mounted on the mounting base, and the other end is connected below the support platform. One end of the second leg is equipped with a pulley, which is slidably mounted in the groove. The other end is connected below the support platform. The first and second legs are hinged together. The hydraulic lifting device includes an angle shaft, a hydraulic cylinder, a return spring, a connecting chain plate, a rocker arm, a support plate, and a pressure rod. The angle shaft is mounted on the first outrigger. One end of the hydraulic cylinder is movably connected to the angle shaft, and the other end is provided with a cylinder base. The cylinder base is fixed with a cylinder pressure rod and a support plate. A pin is provided at the end of the cylinder pressure rod. The return spring is mounted on the cylinder pressure rod and is limited by the pin. The pressure rod is mounted on the rocker arm. The rocker arm is movably mounted on the support plate by a pin. The two ends of the connecting chain plate are movably connected to the pin and the rocker arm, respectively, by pins.

[0006] In the above structure: the portable hydraulic pallet truck proposed by this utility model includes a support platform, outriggers, a front support, a rear support, a sliding track, and a hydraulic lifting device. The support platform is used to place transported items. The front support, rear support, and sliding track form the bottom platform of this device. The front support and rear support are connected and fixed through the sliding track. The outriggers are installed between the bottom platform and the support platform. The outriggers are extended or retracted through the hydraulic lifting device. When the outriggers are extended, the support platform rises accordingly. When the outriggers are retracted, the support platform falls accordingly. The operation is extremely simple.

[0007] The outrigger includes a first leg and a second leg. A mounting base is provided on the front support. One end of the first leg is movably mounted on the mounting base, and the other end is connected to the bottom of the support platform. A sliding groove is provided on the side wall of the sliding track. One end of the second leg is equipped with a pulley, which is slidably mounted in the sliding groove. The other end is connected to the bottom of the support platform. The first leg and the second leg are hinged. When the support platform is raised or lowered by a hydraulic lifting device, the second leg can slide in the sliding groove via the pulley, while the first leg is movably mounted on the mounting base.

[0008] The hydraulic lifting device includes an angle shaft, a hydraulic cylinder, a return spring, a connecting chain plate, a rocker arm, a support plate, and a pressure rod. The angle shaft is mounted on the first outrigger. One end of the hydraulic cylinder is movably connected to the angle shaft, and the other end is fitted with a cylinder base. The cylinder base is fixed with a pressure rod and a support plate. A pin is located at the end of the pressure rod. The return spring is mounted on the pressure rod and limited by the pin. The pressure rod is mounted on the rocker arm, which is movably mounted on the support plate via pins. Both ends of the connecting chain plate are connected by pins. The dynamic connection is between the shaft pin and the rocker arm. During use, the pressure rod is continuously pressed, which drives the hydraulic cylinder pressure rod to move. The hydraulic cylinder pressure rod squeezes the hydraulic cylinder to produce oil, which drives the hydraulic rod at the end of the hydraulic cylinder to extend or retract. The hydraulic rod drives the angle shaft to rotate, which in turn drives the first outrigger to move. Since the first and second outriggers are hinged, the outrigger frame can be extended or retracted. When the outrigger frame is extended, it causes the support platform on it to rise, and when the outrigger frame is retracted, it causes the support platform on it to fall.

[0009] Furthermore, it also includes an armrest, one end of which is fixed to the rear support.

[0010] In the above structure: the handrail is installed on the rear support to facilitate the staff to push the transport cart.

[0011] Furthermore, it also includes support rods, and the support leg frame is provided in two sets, with the two sets of support leg frames connected by support rods.

[0012] In the above structure, there are two sets of outriggers, which are installed in parallel on the front support and / or the support. The two are connected and fixed by support rods, making the pallet truck more stable when in use.

[0013] Furthermore, it also includes wheels, which are fixed under the front bracket and the rear bracket respectively.

[0014] In the above structure, the wheels are fixed under the front and rear supports respectively, which facilitates pushing.

[0015] Furthermore: a support plate fixing block is fixed above the hydraulic cylinder rod, the support plate is fixed on the support plate fixing block, and the support plate is arranged parallel to the hydraulic cylinder rod.

[0016] In the above structure: the support plate fixing block is used to install and fix the support plate.

[0017] Furthermore, the hydraulic lifting device also includes a rear fixing pin seat, which is coaxially mounted on the rocker arm with the support plate.

[0018] In the above structure: the rear fixing pin seat is coaxially mounted on the rocker arm with the support plate, which can protect the support plate and the rocker arm.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This utility model achieves the vertical movement of the support platform through two sets of hinged support legs and a hydraulic lifting device, thereby enabling the rapid loading of goods on the ground. When using it, the operator can control the hydraulic lifting device by stepping on it from the rear of the transport vehicle, which greatly improves the safety performance. Moreover, this application has multiple handling modes to meet the needs of various work scenarios. It can realize the loading and unloading of equipment on the production site, with a wide range of applications and high efficiency. Attached Figure Description
