Problems solved by technology

In order to improve the lifting performance of the loading end, the current handling loaders generally adopt the forward rotation eight-bar linkage or the forward rotation six-bar linkage mechanism, which generally has problems such as short loading stroke, insufficient driving force and lifting force, so it is necessary to solve the common handling and loading mechanism In the process of moving goods and loading, the problem of insufficient handling force and small stroke can better improve the efficiency of handling and loading

Embodiment 1

[0019] Embodiment 1: The present invention provides a transporting and loading mechanism for improving arm stroke and driving force, its structure is as follows figure 1 Shown is a schematic structural view of a preferred embodiment. The present invention comprises sequentially articulated frame 1, boom 2, stick 3, and terminal actuator 4; Hinged by hinge R9, the other end of the arm is hinged with the terminal actuator by hinge R12. The present invention is also provided with frame connecting rods 5 , arm connecting rods 6 , boom hydraulic cylinders 7 , arm hydraulic cylinders 9 and terminal actuator hydraulic cylinders 11 installed in pairs.

[0020] The boom 2 described in the present invention is symmetrically provided with a pair of upper hinged ears 22 and middle hinged ears 21 in the upper and middle parts of the side facing the terminal actuator respectively, and hinged holes are opened in the hinged ears.

[0021] The ends of the cylinder sleeves of the pair of boom...

Embodiment 2

[0024] Embodiment 2: The present invention provides a transporting and loading mechanism for improving arm stroke and driving force, its structure is as follows figure 2 As shown, the transport loader of this embodiment is used as a mine-used front shovel hydraulic excavator, and its structure is basically the same as that of Embodiment 1. The difference is that the boom 2 is only symmetrically provided with a pair of middle articulation ears 21 in the middle. One end of the hydraulic cylinder barrel 11 of the terminal actuator is hinged with the terminal actuator 4 through the hinge R11, and the end of the piston rod 12 of the hydraulic cylinder of the terminal actuator is hinged at the middle part of the arm connecting rod 6 through the hinge R10, that is, the second A hinged way. In the handling loader of this embodiment, the end of the piston rod 12 of the hydraulic cylinder of the terminal actuator is hinged to the middle part of the arm connecting rod 6, and a forward r...

Abstract

The invention relates to a transferring and loading mechanism for increasing the stroke and driving force of a bucket rod. The transferring and loading mechanism for increasing the stroke and driving force of the bucket rod comprises a machine frame, a movable arm, the bucket rod, a terminal execution mechanism, machine frame connecting rods, bucket rod connecting rods, movable arm hydraulic cylinders, bucket rod hydraulic cylinders and terminal execution mechanism hydraulic cylinders, wherein the machine frame connecting rods, the bucket rod connecting rods, the movable arm hydraulic cylinders, the bucket rod hydraulic cylinders and the terminal execution mechanism hydraulic cylinders are symmetrically installed respectively. According to the transferring and loading mechanism for increasing the stroke and driving force of the bucket rod, the upper portion and the middle portion of the movable arm are each provided with a pair of hinging lugs; the two ends of each movable arm hydraulic cylinder is hinged to the machine frame and the movable arm; one end of each machine frame connecting rod is hinged to the machine frame, and the other end of each machine frame connecting rod is hinged to the corresponding bucket rod connecting rod; the other end of each bucket rod connecting rod is hinged to the bucket rod; bucket rod hydraulic cylinder barrels are hinged to the machine frame connecting rods, and the ends of piston rods of the bucket rod hydraulic cylinders are hinged to the machine frame; terminal execution mechanism hydraulic cylinder barrels are hinged to the terminal execution mechanism, and the ends of piston rods of the terminal execution mechanism hydraulic cylinder barrels are hinged into the hinging lugs on the upper portion of the movable arm or into the bucket rod connecting rods. The transferring and loading mechanism for increasing the stroke and driving force of the bucket rod is simple and compact in structure; by additionally arranging the machine frame connecting rods, the bucket rod connecting rods and the bucket rod hydraulic cylinders, the movement distance of the bucket rod can be remarkably increased, and the purpose of increasing the stroke and driving force of the bucket rod is achieved.

Description

technical field [0001] The invention relates to a transporting and loading mechanism for improving the stroke and driving force of a stick, in particular to a loading mechanism suitable for engineering construction excavation and transporting, which can be widely used in the industrial field of material transporting and loading. Background technique [0002] At present, the handling loader is widely used in the construction and transportation industries, and the handling and loading of raw materials for industrial production. The handling and loading mechanism of the handling loader is the main component to complete various functions of handling and loading. In the handling and loading operation of the handling loader, because the volume and quality of the goods and materials are getting larger and larger, the requirements for the handling and loading stroke and driving force are getting higher and higher. In order to improve the lifting performance of the loading end, the c...
