Problems solved by technology

[0003] For the above situations: when the installer holds the pin shaft, it is easy to hit the installer's hand during the smashing of the pin shaft; In addition, it is not easy to align the pin shaft and the center line of the pin hole, so that the pin shaft is not easy to install, the installation process is long, and the labor is laborious. At the same time, there are potential safety hazards for the installer; and performance damage, affecting the secondary use of the pin shaft

Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0018] like figure 1 As shown, a new type of hydraulic pinning device includes a pinning bracket for placing the connecting pin shaft 9, and the pinning bracket includes channel steel one 2, channel steel two 8 and cylinder supporting plate 4, and the groove Steel No. 8 cooperates with Channel No. 2 to form a slideway. The connecting pin 9 is placed between the No. 2 Channel No. 8 and No. 1 Channel No. 2 and can slide along the slideway. At the tail end of steel 1 2 and channel steel 2 8, the oil cylinder supporting plate 4 is provided with a hydraulic pin-through oil cy...

Abstract

The invention discloses a novel hydraulic pin penetrating device and belongs to the linkage field of tower crane pin shafts. The device comprises a pin penetrating bracket used for containing a linkage pin shaft. The pin penetrating bracket comprises a first steel channel (2), a second steel channel (8) and an oil cylinder supporting plate (4); the second steel channel and the first steel channel are matched to form a slide way; the linkage pin shaft (9) is placed between the second steel channel and the first steel channel and can slide along the slide way; and the oil cylinder supporting plate is arranged at the tail end of the first steel channel and the tail end of the second steel channel and is provided with a hydraulic pin penetrating oil cylinder providing power. A slider (6) is arranged between the first steel channel and the second steel channel and provided with a bolt (3) and a screw (5); an oil cylinder force application screw drives the slider and pushes the linkage pin shaft to move to the linkage position; and a stand pin (7) used for positioning the slider is arranged on the second steel channel. According to the hydraulic pin penetrating device, time and force are saved and operation is convenient and safe when the pin shaft is installed, installing efficiency can be improved, damage caused when the pin shaft penetrates in can also be avoided, and the secondary use rate of the pin shaft is increased.

Description

technical field [0001] The invention relates to a pin threading device, in particular to a novel hydraulic pin threading device, which belongs to the field of pin connection of tower cranes. Background technique [0002] At present, the connection between structural parts of tower cranes mostly adopts the pin shaft connection form. There are no other structural parts to support the pin shaft on the structure of the pin shaft, and all rely on the original method. When the pin is light, the installer supports the pin with his hands; when the pin is heavy, hemp rope is used to cover the pin, and several installers hold the hemp rope to support the pin. [0003] For the above situations: when the installer holds the pin shaft, it is easy to hit the installer's hand during the smashing of the pin shaft; In addition, it is not easy to align the pin shaft and the center line of the pin hole, so that the pin shaft is not easy to install, the installation process is long, and the la...
