Description
Technical Field
The utility model relates to a breaker maintenance of equipment technical field, in particular to change PXZ900 breaker hydraulic cylinder bush's device.
Background
At present, when PXZ900 breaker hydraulic cylinder bush needs to be changed, because do not have specialized tool, often need to dismantle hydraulic cylinder and just can carry out the bush change, waste time and energy, work efficiency is low.
SUMMERY OF THE UTILITY MODEL
To the technical problem, the utility model provides a change PXZ900 breaker hydraulic cylinder bush's device for solve present change PXZ900 breaker hydraulic cylinder bush, do not have specialized tool, must dismantle hydraulic cylinder and just can carry out the bush and change, the work efficiency who brings is low, the problem that wastes time and energy.
In order to realize the purpose, the technical scheme of the utility model is specifically as follows:
an apparatus for replacing PXZ900 crusher hydraulic cylinder liner, comprising:
the cross-shaped support structure is assembled after being placed inside the lining;
the cardboard, vertical setting is on four end of bearing structure, when dismantling the lower liner cover part of bush, the cardboard can with the last edge joint of lower liner cover part, when dismantling the last liner cover part of bush, the cardboard can with the bottom joint of last liner cover part.
The support structure includes:
the clamping plates are arranged at two ends of the two clamping steel plates respectively;
two connecting steel plates set separately on two sides of the clamping steel plates to form a cross structure, and the ends of the two connecting steel plates are provided with the clamping plates.
The outside of cardboard and bearing structure junction is provided with can with the dop of the upper edge of lower liner part and the bottom joint of upper liner part.
The beneficial effects of the utility model are that: the utility model discloses a can be in the inside limited operation space of bush, carry out the operation, put into the bush with criss-cross bearing structure and assemble after inside, simultaneously on four end of bearing structure vertical cardboard that sets up, when dismantling the lower bush part of bush, cardboard and the last joint of following of bush part down, through lifting by crane equipment to bearing structure's pushing down, with the partial extrusion of bush down, when dismantling the last bush part of bush, the cardboard is with the bottom joint of last bush part, through lifting by crane equipment to bearing structure lift, will go up the bush part and propose. The utility model discloses preparation processing is simple, and the practicality is stronger, with overhead traveling crane cooperation operation, has liberated the manpower, and the safety risk reduces, has stopped a limited operation activity, has guaranteed staff's safety. The utility model provides a when changing PXZ900 breaker hydraulic cylinder bush, must dismantle hydraulic cylinder's history, stopped a limited space operation activity, reduced the maintenance frequency, reduced the safety risk.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
As shown in fig. 1, a device for replacing PXZ900 crusher hydraulic cylinder liner includes: the cross-shaped support structure is assembled after being placed inside the lining; cardboard 1, vertical setting is on bearing structure's four end, and when dismantling the lower liner bushing part 5 of bush, cardboard 1 can with the last joint along of lower liner bushing part 5, when dismantling the last liner bushing part 4 of bush, cardboard 1 can with the bottom joint of last liner bushing part 4.
As shown in fig. 1 and 2, the support structure includes: the clamping plates 1 are respectively arranged at two ends of the two clamping steel plates 2; two connecting steel plate 3 set up respectively in two 2 both sides of centre gripping steel sheet, constitute cruciform structure, and 3 ends of two connecting steel plate all are provided with cardboard 1.
As shown in fig. 2 and 3, the outer side of the joint of the clamping plate 1 and the supporting structure is provided with a clamping head which can be clamped with the upper edge of the lower bushing part 5 and the bottom of the upper bushing part 4.
When the utility model is used, firstly, two clamping steel plates 2 and two connecting steel plates 3 are placed in a bushing, then, the assembly welding is carried out to form a cross-shaped supporting structure, a clamping plate 1 is vertically welded on four ends of the supporting structure, when a lower bushing part 5 of the bushing is disassembled, a clamping head of the clamping plate 1 is clamped with an upper edge of the lower bushing part 5, and then, a crown block is used for hoisting a movable cone (with the weight of 24 tons) to extrude the lower bushing part 5; when the upper liner part 4 of the liner is removed, the chuck of the chuck plate 1 is engaged with the bottom of the upper liner part 4, and the upper liner part 4 is lifted by a crown block (lifting weight 50 tons).
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. Further, it is intended that the appended claims cover all such variations and modifications as fall within the scope and boundaries of the appended claims or the equivalents of such scope and boundaries.
