Abstract
The utility model discloses guide sleeve of stand column pulling attachments, including walking dolly, level is fixedly connected hydraulic cylinder on walking dolly, hydraulic cylinder is connect by outlet tube with control valve a, liquid outlet is provided on control valve a, hydraulic cylinder is connect by inlet tube with control valve b, and inlet is provided on control valve b, is additionally provided with claw on hydraulic cylinder.During overhauling hydraulic support column, even if there is serious corrosion situation in guide sleeve of stand column, safely and fast guide sleeve can also be disassembled using the utility model, avoid the case where being beaten guide sleeve of stand column with tools such as hammers at present, it is made to fall off and equipment is made to be damaged.
Description
Technical field
The utility model belongs to mechanical equipment technical field, and in particular to a kind of guide sleeve of stand column pulling attachment.
Background technique
During overhauling hydraulic support column, guide sleeve of stand column usually will appear very serious corrosion situation, existing skill
In art, guide sleeve of stand column usually is beaten with tools such as hammers, it is made to fall off, this method for dismounting not only wastes time, moreover, often
Column can be often undermined, makes equipment by a degree of damage.
Utility model content
The purpose of the utility model is to provide a kind of guide sleeve of stand column pulling attachments, solve existing in the prior art tear open
Except guide sleeve of stand column wastes time, while making the problem of equipment is by a degree of damage.
The utility model is the technical scheme adopted is that guide sleeve of stand column pulling attachment, including walking dolly, walking dolly
Upper level is fixedly connected hydraulic cylinder, and hydraulic cylinder is connect by outlet tube with control valve a, and liquid outlet, liquid are provided on control valve a
Cylinder pressure is connect by inlet tube with control valve b, and inlet is provided on control valve b, is additionally provided with claw on hydraulic cylinder.
The utility model is also characterized by:
Control valve a, control valve b are fixedly connected on walking dolly.
The two sides of hydraulic cylinder front end have been respectively fixedly connected with a pair of bolts earhole, and there are four claws, four claw every two
It is bolted respectively in this for one group between bolt earhole, and two claws of every side are arranged successively up and down.
Height between the two panels bolt earhole of each pair of bolt earhole is greater than the sum of the thickness of two claws.
Claw is in J-shaped.
The beneficial effects of the utility model are:
It is practical using this even if serious corrosion situation occurs in guide sleeve of stand column during overhauling hydraulic support column
It is novel safely and fast to disassemble guide sleeve, it avoids and beats guide sleeve of stand column with tools such as hammers at present, make it
The case where falling off and equipment made to be damaged.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model column oil cylinder guide sleeve pulling attachment.
In figure, 1. walking dollies, 2. hydraulic cylinders, 3. outlet tubes, 4. inlet tubes, 5. control valve a, 6. control valve b, 7. block
Pawl, 8. liquid outlets, 9. inlets.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
It is horizontal on walking dolly 1 as shown in Figure 1, the utility model guide sleeve of stand column pulling attachment, including walking dolly 1
It is welded hydraulic cylinder 2, inlet tube 4 and outlet tube 3 are connected on hydraulic cylinder 2, outlet tube 3 is connected by control valve a5 and liquid outlet 8
It connects, inlet tube 4 is connect by control valve b6 with inlet 9.Control valve a5 and control valve b6 is fixedly connected on the handle of walking dolly 1
On hand, the two sides of 3 front end of hydraulic cylinder have been respectively fixedly connected with a pair of bolts earhole, and there are four claws 7, four 7 every two of claw
It is bolted respectively in this for one group between bolt earhole, and about 7 two claws of every side are arranged successively, each pair of bolt
Height between the two panels bolt earhole of earhole is greater than the sum of the thickness of described two claws 7, therefore claw 7 can be in level side
It is rotated up, so as to adapt to the guide sleeve of different path lengths.
The working process of the utility model is as follows: before the utility model guide sleeve of stand column pulling attachment is pushed into column oil cylinder,
Inlet 9 is connected with the outlet tube of pumping plant, liquid outlet 8 is connected with the inlet tube of pumping plant, then, Level tune claw 7 it
Between distance, match it with guide sleeve path length, and catch on guide sleeve, then, start pumping plant, opening controlling valve b6 makes hydraulic
The piston rod of cylinder 2 stretches out, and guide sleeve is pulled out by the power of opposite direction immediately, finally, control valve b6, opening controlling valve a5 are closed,
The piston rod of hydraulic cylinder 2 is withdrawn, pumping plant is closed, the utility model guide sleeve of stand column pulling attachment restPoses.
