Description

Technical Field

[0001] This utility model relates to the field of lifting mechanism technology, specifically a lifting mechanism with horizontal pushing function. Background Technology

[0002] In the fields of industrial automation and material handling, lifting mechanisms are key components for lifting and transporting goods, and are widely used, especially in ultra-low AGVs or RGV powered vehicles.

[0003] Furthermore, existing lifting mechanisms are insufficient in terms of load-bearing stability. During lifting, especially under heavy loads, the stability of the mechanism is crucial. Traditional lifting designs, lacking a reasonable stress-distribution structure, are prone to swaying or tilting during lifting and load-bearing, affecting the safety of the cargo and the lifting accuracy. This unstable lifting method may not only damage the cargo but also harm the equipment itself, and even cause safety accidents.

[0004] Furthermore, the use of multiple hydraulic cylinders for lifting results in higher costs, and the vertical lifting method requires greater thrust from the hydraulic cylinders, which also reduces their service life. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a lifting mechanism with horizontal pushing, which can solve the problems in the prior art.

[0006] This utility model is achieved through the following technical solution: A lifting mechanism with horizontal pushing of this utility model includes a movable plate assembly, characterized in that a guide wheel assembly is provided on the lower side of the movable plate assembly to guide the movable plate assembly, and a push rod assembly is also included. The push rod assembly drives the movable plate assembly to move horizontally. The movable plate assembly includes an inclined surface, and a lifting assembly is provided on the inclined surface. After the movable plate assembly is pushed by the push rod assembly, the lifting assembly cooperates with the inclined surface to lift upward, reaching the highest point when it is on the horizontal surface.

[0007] In a further technical solution, the guide wheel assembly includes a guide wheel, the moving plate assembly includes a sliding groove, the guide wheel rolls against the end wall of the sliding groove, the lifting assembly includes a pulley, the pulley rolls against the inclined surface, and the housing part of the pulley is fixedly provided with a lifting shaft.

[0008] In a further technical solution, a guide sleeve is provided on the outer surface of the lifting shaft.

[0009] In a further technical solution, a pulley groove is provided inside the pulley, a guide wheel groove is provided inside the guide wheel, the pulley groove rolls against the upper wall of the inclined surface, and the pulley groove rolls against the end wall of the groove.

[0010] In a further technical solution, a spherical groove is also provided inside the slide.

[0011] A further technical solution includes a push rod assembly comprising a hinged seat, a hydraulic cylinder hingedly disposed within the hinged seat, a telescopic push rod disposed within the hydraulic cylinder, and a connecting seat hingedly disposed at the end of the push rod, the connecting seat being fixedly connected to the movable plate assembly.

[0012] In a further technical solution, a connecting beam is fixedly provided on one side of the connecting seat, and the connecting beam is fixedly connected to the movable plate assembly.

[0013] In a further technical solution, when the movable plate assembly includes multiple push plates and connecting plates, the connecting beam is fixedly connected to the push plates.

[0014] In a further technical solution, when the moving plate assembly includes multiple push plates and connecting plates, the push plates and connecting plates are fixedly connected, the inclined surface and the horizontal surface are disposed on the top of the push plate, and the sliding groove and the spherical groove are disposed inside the push plate.

[0015] The beneficial effects of this utility model are as follows: First, the hinge seat in the push rod assembly, the guide wheel in the guide wheel assembly, and the guide sleeve in the lifting assembly are all fixed to the vehicle body or other machine body. This mechanism drives the moving plate assembly to move through the push rod assembly, so that when the inclined surface on the moving plate assembly contacts the pulley in the lifting assembly, it can drive the lifting shaft to lift upward relative to the guide sleeve, so as to realize the horizontal pushing lifting function. The overall height of this mechanism is set low, and the compact design can be used in ultra-low type AGV or RGV power vehicles.

[0016] Second, by placing the lifting assembly directly above the guide wheel assembly, i.e., the pulley is positioned directly above the guide wheel, the weight of the lifting bearing can be effectively transferred to the guide wheel after the guide wheel rolls against the end wall of the slide groove, thereby improving the load-bearing capacity of the mechanism.

[0017] Third, by setting a horizontal plane, the pulley can abut against the pulley, keeping the lifting assembly at its highest point. At the same time, a spherical groove is set to give the guide wheel enough space to be located directly below the pulley, which improves the structural stability of the lifting assembly in maintaining its highest point.

[0018] Fourth, the use of a horizontally driven push rod assembly reduces the thrust of the hydraulic cylinder while achieving the same lifting function, thus improving the lifespan of the hydraulic cylinder. Attached Figure Description

[0028] Advantageously, the guide wheel 25 can roll against the upper or lower end wall of the slide groove 24, or roll against the upper or lower end wall simultaneously.

[0029] Advantageously, when the lifting assembly is located directly above the guide wheel assembly, the pulley 44 is located directly above the guide wheel 25.

[0030] Advantageously, the outer surface of the lifting shaft 26 is provided with a guide sleeve 28, which is fixedly mounted on the vehicle body or other body, thereby enabling the lifting shaft 26 to have the function of guiding and sliding up and down.

[0031] Advantageously, the pulley 44 is provided with a pulley groove 43, the guide wheel 25 is provided with a guide wheel groove 42, the pulley groove 43 rolls against the upper end surface of the inclined surface 32, and the pulley groove 43 rolls against the end wall of the slide groove 24.

[0032] Advantageously, a horizontal surface 33 is provided on one side of the inclined surface 32, and after the movable plate assembly moves, the horizontal surface 33 rolls against the pulley 44.

[0033] Advantageously, a spherical groove 23 is also provided in the slide 24. After the moving plate assembly moves, the contact point between the spherical groove 23 and the slide 24 engages with the guide wheel 25 to reach the limit position of the moving plate assembly.

[0034] Advantageously, the push rod assembly includes a hinge seat 11 fixedly mounted on the vehicle body or other machine body. A hydraulic cylinder 12 is hingedly mounted inside the hinge seat 11. A telescopic push rod 13 is mounted inside the hydraulic cylinder 12. A connecting seat 15 is hingedly mounted at the end of the push rod 13. The connecting seat 15 is fixedly connected to the movable plate assembly. The hydraulic cylinder 12 is connected to a hydraulic pump station mounted on the vehicle body or other machine body to realize the power transmission function.

[0035] Advantageously, a connecting beam 16 is fixedly provided on one side of the connecting seat 15, and the connecting beam 16 is fixedly connected to the movable plate assembly.

[0036] Advantageously, when the movable plate assembly includes multiple push plates 21 and connecting plates 22, the connecting beam 16 is fixedly connected to the push plates 21.

[0037] Advantageously, the movable plate assembly includes multiple push plates 21 and connecting plates 22, which are fixedly connected. The fixed connection between the push plates 21 and connecting plates 22 can be achieved by welding or fastener connection, or they can be set as an integral part. An inclined surface 32 and a horizontal surface 33 are provided on the top of the push plate 21, and a sliding groove 24 and a spherical groove 23 are provided inside the push plate 21.

The guide wheel 25 in the guide wheel assembly rolls against the upper wall of the slide groove 24 in the moving plate assembly, so that the moving plate assembly moves smoothly. When the pulley 44 is set directly above the guide wheel 25, the load-bearing capacity can be effectively improved.

[0039] When the mechanism is in operation, the hydraulic cylinder 12 causes the push rod 13 to be hydraulically pushed out. Since the push rod 13 is hinged to the connecting seat 15, and the connecting seat 15, connecting beam 16, push plate 21, and connecting plate 22 are fixedly connected, the push plate 21 and the connecting plate 22 can be moved. Since the push plate 21 is provided with a sliding groove 24, and the upper wall of the sliding groove 24 rolls against the guide wheel 25, the push plate 21 and the connecting plate 22 can be guided and moved in parallel.

[0040] After the pulley 44 rolls against the inclined surface 32, due to the parallel sliding of the push plate 21 and the inclined surface 32 being set at an angle, the pulley 44 and the lifting shaft 26 are driven to rise upward, causing the lifting shaft 26 to slide upward from the guide sleeve 28. When the pulley 44 moves to the horizontal surface 33, the lifting shaft 26 rises to the highest point.
