The invention provides an engineering machinery counter weight penetrating pin device. The engineering machinery counter weight penetrating pin device comprises a rotary platen, a connecting plate, a penetrating pin shaft, a penetrating pin oil cylinder and mounting shafts. The mounting shafts are arranged in parallel with the penetrating pin shaft, and the first ends of the mounting shafts are fixedly connected with the connecting plate. A pin head is provided with a first clamping groove in the radial direction of the pin head, and the end of an oil cylinder rod of the penetrating pin oil cylinder is provided with a clamping head matched with the first clamping groove. The connecting plate is provided with second clamping grooves having the same clamping direction as the first clamping groove, and the second ends of the mounting shafts are clamped in the second clamping grooves and are provided with locking components. After the mounting shafts are clamped and locked through the locking components, the position of the oil cylinder rod is limited, the degree of freedom of the oil cylinder rod in the vertical direction is limited, and the purpose of fastening installation is realized. By the adoption of the structure, the engineering machinery counter weight penetrating pin device can be dismounted in the radial direction, and the purpose of providing the engineering machinery counter weight penetrating pin device with a low requirement for axial dismounting space is realized. The invention further provides a crane.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, more specifically, to a counterweight pin-threading device of an engineering machinery. The invention also relates to a crane. Background technique [0002] With the development of my country's economic construction, my country's use of hoisting machinery is becoming more and more extensive. [0003] At present, the counterweight pinning device of crawler cranes can be disassembled freely, and the disassembly form of the counterweight pinning device of crawler cranes is mostly: there is a counterweight pinning device on the inside of the counterweight, which is installed with the turntable through a threaded shaft to achieve fixation. . Since it cannot be disassembled perpendicular to the ground, it can only be disassembled axially, which requires a large axial disassembly space, which brings inconvenience to the disassembly work. [0004] Therefore, how to provide a construction...
