[0001] The invention relates to the field of excavators, and in particular to a working method of construction equipment. Background Art

[0002] With the rapid development of my country's economy, the demand for railway tunnel construction is also increasing. In addition to the commonly used shield tunneling machines, the market demand for tunneling machines with buckets for non-explosive excavation is also increasing. In the current field of mechanical construction, especially for industrial and civil buildings, water conservancy and hydropower projects, farmland transformation projects, oil field and port facility construction, transportation networks, mining operations and a series of modern military projects, the application of construction machinery is particularly critical and important. These projects generally rely on a series of high-performance mechanical equipment, including but not limited to tunneling equipment, loading machinery and tower cranes, etc., to ensure the improvement of construction efficiency, quality and safety. Because the tunneling machine has the characteristics of high technical integration, strong functional complexity, high work efficiency, strong operating capacity and wide application range, it can greatly reduce the physical labor burden of workers, while saving the cost of engineering construction, so that the project can be completed on time with quality and quantity guaranteed. At present, hydraulic tunneling machines are playing an increasingly important role in engineering construction.

[0003] In actual engineering practice, there are the following problems:

[0004] 1. In the prior art excavator, the arm performs a bending action to dig deep (such as the present invention Figure 3 ) When the actuator is in motion, a large torque is generated, which will cause a large load on related components, thereby reducing stability and shortening service life.

[0005] Second, in the prior art excavator, there are multiple pivot shafts, and when the corresponding pivot holes are worn, it is difficult to replace and maintain them because the pivot holes are connected to the base and other parts as a whole.

[0006] 3. Excavators in the prior art require different digging angles under different working conditions, for example Figure 1 In the case of excavation in a horizontal position such as a tunnel or a wall, the arm is set in a relatively horizontal position, such as Figure 3 The working condition of the curved arm digging the ground is shown, and the arm is set in a relatively curved position; the requirements under different working conditions are different.

[0022] The beneficial effects of the present invention are:

[0023] Invention point 1, in response to the first point raised in the background technology, the adopted technical means is: in the prior art, a pivot seat is generally provided on the base of the excavator for connecting the bottom of the hydraulic cylinder. Invention point 1 sets a block in the pivot seat to limit the pivot angle of the main oil cylinder, thereby providing a more stable support to resist the larger torque caused by the bending action.

[0024] At the same time, a series of blocks of different sizes are set up to adapt to different limit angles, and a placement portion is further set on the support to place blocks of different sizes, so that there is no need to specifically go to the tool library to find blocks of different specifications, which facilitates quick replacement at the construction site.

[0025] Invention point 2: In response to the first point raised in the background technology, the second technical means adopted is: in the prior art, the telescopic cylinder generally pivots at one position, and the force it provides to the entire arm also originates from one point. Invention point 2 is to disperse the force or torque provided by this one point to multiple components. When the excavating arm digs deep and shakes the head, the force is more evenly dispersed through the triangular blocks, thereby providing a more stable and stronger structure.

[0026] Invention point three, in response to the second point raised in the background technology, the pivot seats in the prior art are all arranged on the base, and the present invention lifts the pivot seat away from the base to provide a larger disassembly and assembly space; at the same time, the pivot seat that is not easy to disassemble and assemble is decomposed into a fixed part and a disassembly part, and the disassembly part can be directly disassembled during disassembly; in addition, the wear when the shaft and the shaft hole are matched is mostly caused by the skewness of the shaft, so the wear of the shaft hole occurs at the outer edge of the shaft hole, so the invention point three arranges the disassembly and assembly part on the outside of the corresponding shaft hole, and when wear occurs, the wear position is located in the hole on the plate body of the sub-plate, and only the sub-plate needs to be disassembled and replaced, which is convenient for disassembly and assembly.

[0027] Invention point four, in response to the first and second points proposed in the background technology (i.e., invention point one and invention point three), invention point four makes an organic combination, and integrates the stopper mentioned in invention point one with the disassembly and assembly part (sub-plate) mentioned in invention point three through an overall structure, so that the stopper and the disassembly and assembly part form an organic whole, making the structure simpler, and realizing the functions of two parts through one component; at the same time, through the provision of the sub-plate, the strength of the main board is enhanced; in addition, through the provision of the outer plate, it can be directly connected to the circular ring on the pivot seat (in the prior art, only half of the ring can be connected to the plate, such as the fixed part, and a whole ring cannot be formed), thereby enhancing the strength and thickness of the pivot seat, and thus four functions are integrated through one component.

[0028] Invention point five, in response to the third point raised in the background technology, an adjustment part is provided under the telescopic cylinder to adjust the support height below the cylinder. After the adjustment part is raised, better support force can be provided for the cylinder. After the adjustment part is removed, a larger space can be provided for the cylinder to rotate flexibly, thereby providing a structure that is convenient for adjustment and disassembly and assembly.
