Description
Technical field
A kind of heavy pin shaft fast assembling-disassembling of the utility model frock, removes for fast dismantling and installs heavy pin shaft.
Background technology
On heavy mechanical equipment and metal structure, a large amount of connection using bearing pin to realize bascule parts.As: the Men Jie etc. of the suspension hook of hoisting machinery, the grid joint of trash rack, Stoplog gate.For adapting to different operating mode or overhauling needs with plant maintenance, as regular in hoisting machinery needs changes suspension hook; Hydraulic Metal needs periodic inspection etc., and these main equipments and metal structure often must be removed, be installed bearing pin.
Because heavy pin shaft heavier-weight, volume are comparatively large, be generally about 0.1-0.5 ton, and bearing pin and shaft hole matching gap less, bearing pin still bearing part self gravitation during dismounting, therefore dismounting task difficulty is larger.And normal conditions lower bearing pin quantity is more, as each trash rack joint just has two bearing pins, pin assembling/disassembling workload is larger.
Traditional way adopts hydraulic lifting equipment or framed bent to coordinate bottle gouard moved by hands mode, bearing pin and axis hole centering is highly made by adjustment, again bearing pin taken out or load axis hole, but the shortcoming of these traditional dismounting modes is: 1, be only suitable for horizontal dismountable, when inclination or vertical station, dismounting difficulty is very large; 2, centering adjustment stroke is large, and dismounting work efficiency is low; 3, frock volume is large, is unfavorable for the dismounting of narrow space; , easily there is bearing pin slippage casualty accident in 4 poor stability.
Summary of the invention
For the defect of existing dismounting mode, the utility model provides a kind of heavy pin shaft fast assembling-disassembling frock, adopts the mouse cage type structure with hydraulic jacking device, bolt, utilizes the bolt hole of baffle plate on bearing pin to install this frock, realizes bearing pin fast assembling-disassembling.
The technical scheme that the utility model is taked is: a kind of heavy pin shaft fast assembling-disassembling frock, comprise front end-plate, end plate, muscle bar, front end-plate is welded into hollow mouse cage type structure by many muscle bars and end plate, described front end-plate is furnished with bolt hole, described muscle bar is provided with bolt, described end plate is provided with hydraulic jacking device, and the pipe joint of described hydraulic jacking device is by hydraulic hose connecting fluid press pump.
Described hollow mouse cage type structure is cylindrical, square column type or taper, and it is for retraining bearing pin.
Described hydraulic jacking device is connected with extension bar.
This frock is two, is separately fixed at the symmetrical both sides of pedestal of bearing pin by bolt.
A kind of heavy pin shaft fast assembling-disassembling of the utility model frock, technique effect is as follows:
1), this frock do not depart from axis hole pedestal all the time, in demolition, installation transfer process, need not readjust frock, can continuous production process.
2), bearing pin constrained in frock shaft core position by bolt, and bearing pin and axis hole center can rapid adjustment be located when mounted, and centering adjustment stroke is little, quick for installation.
3, because frock is fixed on axis hole pedestal all the time, bearing pin kinematic constraint is in the enclosure space of frock, and bearing pin all can not landing under any angle, greatly improves processing safety.
4), this frock volume is little, lightweight, easy and simple to handle, only needs a less space to use.Operating personnel can operate at an arbitrary position, are beneficial to the disassemble and assemble work of narrow space or inclination station especially.
5), because frock is directly fixed on axis hole pedestal, tool pedestal that need not be extra, saves frock cost, and this frock making simple process, material is easy to get, economic and practical.
6), the utility model frock, be particularly useful for the heavy pin shaft dismounting at improper station or camp equipment, more can embody convenience and the economy of frock.
Accompanying drawing explanation
Fig. 1 is the utility model tool structure schematic diagram;
Fig. 2 is the utility model frock scheme of installation.
Detailed description of the invention
As shown in Figure 1 and Figure 2, a kind of heavy pin shaft fast assembling-disassembling frock, comprises front end-plate 4, end plate 3, muscle bar 2,
Front end-plate 4 is welded into hollow mouse cage type structure by many muscle bars 2 and end plate 3, and described front end-plate 4 is furnished with bolt hole 1, and described muscle bar 2 is provided with bolt 5, and bolt 5 can adjust bearing pin and realize centering location.Described end plate 3 is provided with hydraulic jacking device 6, and the pipe joint 7 of described hydraulic jacking device 6 is by hydraulic hose connecting fluid press pump.
Described hollow mouse cage type structure is cylindrical, square column type or taper, and it is for retraining bearing pin 9.
Described hydraulic jacking device 6 is connected with extension bar 8, for lengthening hydraulic jacking device 6 stroke.
The described muscle bar 2 with bolt is three, and hollow mouse cage type structure is mutually 120 ° of distributions, and each root muscle bar 2 is furnished with bolt 5.
A kind of heavy pin shaft fast assembling-disassembling of the utility model frock, uses in pairs, utilizes the baffle plate bolt hole on pin shaft hole pedestal (being generally 4 bolts hole), by two the utility model frocks, be separately fixed at the symmetrical both sides of the pedestal of bearing pin 9 with bolt 12.When removing bearing pin, utilize the hydraulic jacking device 6 of end plate 3, bearing pin 9 is released axis hole, it is stand-by that bearing pin 9 enters opposite side frock.When bearing pin is installed, adjusts bearing pin center with the bolt 5 on muscle bar 2, make it to align with axis hole, then with the hydraulic jacking device 6 of frock tail end, bearing pin is pushed axis hole, remove frock; Bearing pin baffle plate is installed, namely completes bearing pin installation process.Bearing pin is not adopted to the main equipment of bolt baffle plate version, also on axis hole pedestal, bolt hole can be drilled separately, re-use the utility model frock and carry out pin assembling/disassembling.
Implementation step:
Removing bearing pin 9 operation is: as shown in Figure 2, removal top base 10, bottom base 11 are applied to the load of bearing pin 9; Remove the baffle plate at bearing pin 9 two ends; Utilize baffle plate bolt hole construction bolt 12, at bearing pin 9 two ends, the utility model frock is respectively installed.Start the hydraulic jacking device 6 of frock tail end, when jacking stroke is inadequate, extension bar 8 can be installed additional, bearing pin 9 is slowly released axis hole, until bearing pin 9 exits axis hole completely, enter opposite side the utility model frock.Tighten the bolt 5 on muscle bar 2, fixed pin shaft 9, then it is stand-by to remove two frocks.As working space allows, also can not remove.Shrink hydraulic jacking device 6, top base 10 and bottom base 11 can realize being separated.
Installing bearing pin 9 operation is: after top base 10, bottom base 11 contraposition, be installed on pedestal by the frock that bearing pin 9 is housed; Adjust bearing pin center with the bolt 5 on muscle bar 2, make it to align with axis hole.Start the hydraulic jacking device 6 of frock tail end, bearing pin 9 is pushed axis hole (extension bar 8 can be installed additional when top lifting height is inadequate), until bearing pin 9 is completely in place; Shrink hydraulic jacking device 6, remove frock; Bearing pin baffle plate is installed, namely completes bearing pin installation process.
