Abstract
The invention discloses a crane boom quick-install device, and relates to the technical field of design of crane boom installing parts. The crane boom quick-install device provided by the invention comprises a plug-in lug plate, wherein one side of the plug-in lug plate is provided with an open type pin shaft insert port, the outer side of the plug-in lug plate is provided with a locking plate matched with the pin shaft insert port, the locking plate and the plug-in lug plate are fit with each other and are in bolted connection, the locking plate is provided with a concave locking port matched with the pin shaft insert port, and a closed pin shaft hole is formed between the pin shaft insert port and the concave locking port in a combined manner. According to the stressing characteristic of the lug plate at the root of a crane boom, a close type pin hole connected with the lug plate is changed into the open type insert port, and by matching the locking plate, a pin shaft can be previously arranged on the ground and then directly inserted to a connecting lug plate of a slewing tower, so that the effects of being rapid, labor-saving, safe and effective are achieved.
Description
Technical field
The present invention relates to crane arm mounting parts design field.
Background technology
On existing tower machine market, the conventional tower machine is closed pin-and-hole owing to connecting otic placode, all first crane arm root otic placode is inserted slewing tower and connect in otic placode when crane arm is installed, and reinstalls bearing pin, because this process effort of aloft work labour intensity consuming time is large.
Summary of the invention
The object of the invention is to provide a kind of simple and reasonable, easy to use labour-saving crane arm quick-mounting device for above problem.
The present invention includes and patch otic placode, described otic placode one side that patches is provided with open type bearing pin socket, the jam plate that is patching the otic placode arranged outside and match with the bearing pin socket, described jam plate with patch otic placode and fit and be bolted, the spill fore shaft that coordinates with the bearing pin socket is set on described jam plate, is combined to form closed pin shaft hole between described bearing pin socket and spill fore shaft.
The present invention changes the closed pin-and-hole that connects otic placode into open jack according to crane arm root otic placode loading characteristic, coordinates jam plate, bearing pin can be installed on ground in advance then directly insert slewing tower connection otic placode, and fast power-saving is safe and effective.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation that patches otic placode.
Fig. 3 is the structural representation of jam plate.
The specific embodiment
As shown in Figure 1, 2, 3, the present invention includes and patch otic placode 1, patch otic placode 1 one sides and be provided with open type bearing pin socket 1-1, the jam plate 2 that is patching otic placode 1 arranged outside and match with bearing pin socket 1-1, jam plate 2 with patch otic placode 1 and fit and be bolted, the spill fore shaft 2-1 that coordinates with bearing pin socket 1-1 is set on jam plate 2, is combined to form closed pin shaft hole 3 between bearing pin socket 1-1 and spill fore shaft 2-1.
