Abstract
The invention relates to the maintenance of plate blank weighing machine.It mainly comprises the beam, hoisting cylinder at both ends of the hanging frame. The change of hoist cylinder goes with the side welded block at the jointing position of the beam and the hoist cylinder which is used to hoist the beam, with chock test inserted between the base and the block, discharging of pressure to let loose the hoist cylinder and the hanging frame, drop off the pins between the hoist cylinder and the beam and that between the hanging frames to change hoist cylinder, charging it to elevate the beam, remove the chock test, discharge pressure and let down of the hoist cylinder. This change method does not occupy any vehicles, with less construction time and removal of safety issue.
Description
Technical field
The present invention relates to the plate blank weighing machine method for maintaining, particularly a kind of plate blank weighing machine lifting cylinder changing method.
Background technology
The plate blank weighing machine primary structure is to promote all lift cylinder at crossbeam and crossbeam two ends of slab, and the two ends lift cylinder promotes the weighing slab with crossbeam during work, and therefore, the lift cylinder loss is serious, needs often to change.Existing method is to use driving and wire rope that crossbeam is caught earlier, dismantle lift cylinder then and weigh the pin that is connected, throw off pin with the crossbeam certain altitude of slinging, the workmen gets in the trench below the crossbeam and fills up sleeper, after the sleeper height is suitable crossbeam fallen and be put on the sleeper, change lift cylinder then.This method need take driving, influences the project that other need be driven a vehicle, and the workmen is many, the time is long, has bigger potential safety hazard.
Summary of the invention
Problem to be solved by this invention is that existing replacing lift cylinder method need take driving, needs many people to spend the plenty of time, and has potential safety hazard, and a kind of plate blank weighing machine lifting cylinder changing method is provided.Plate blank weighing machine lifting cylinder changing method of the present invention does not take driving, and construction is short man-hour, and eliminates safe hidden trouble.
A kind of plate blank weighing machine lifting cylinder changing method, plate blank weighing machine mainly comprise the lift cylinder at crossbeam and crossbeam two ends, and described replacing method is carried out according to following step:
A respectively welds a block at the crossbeam and the outside, lift cylinder junction;
B utilizes lift cylinder to promote crossbeam, pad one cushion block between plate blank weighing machine base and block;
C sheds pressure, makes lift cylinder and suspension bracket be in lax connection status;
D throws off the pin between lift cylinder and crossbeam and the suspension bracket, changes lift cylinder, wears pin;
E, the lift cylinder pressurization, the lifting crossbeam removes cushion block;
F sheds pressure, puts down lift cylinder.
Cushion block among the described step b is the steel cushion block, and thickness is not less than 25mm.
The present invention utilizes lift cylinder to mention crossbeam, does not need to take driving, for other projects under construction have been created condition.The workmen need not get into the weighing machine below and put sleeper, but put the steel cushion block on weighing machine limit, ground, the place is open, bright and clear, eliminate safe hidden trouble, and because in terrestrial operation, whole lift cylinder more changes jobs and is reduced to 3 people about 40 minutes by original workload of 8 hours of 5 people, increases work efficiency more than 6 times.And do not need to weld block when changing lift cylinder once more, directly lift lift cylinder and get final product.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is a synoptic diagram of the present invention.
Embodiment
As shown in Figure 1, a kind of plate blank weighing machine lifting cylinder changing method, plate blank weighing machine comprise main lift cylinder 3 by crossbeam 1 and suspension bracket 2 two ends, and described replacing method is carried out according to following step:
A respectively welds a block 4 at the crossbeam 1 and the outside, lift cylinder 3 junctions, guarantees to connect reliable;
B utilizes lift cylinder 3 to promote crossbeam 2, pad one cushion block 5 between plate blank weighing machine base ground and block 4;
C sheds pressure, makes lift cylinder 3 and crossbeam 1 and suspension bracket 2, utilizes cushion block 5 support limit stops 4 and supports weighing machine;
D throws off the pin between lift cylinder 3 and the crossbeam 1, changes lift cylinder 3;
E, lift cylinder 3 pressurizations, lifting crossbeam 1 removes cushion block 5;
F sheds pressure, puts down lift cylinder 3.
Cushion block among the described step b is the steel cushion block, and thickness is not less than 25mm, generally is 30mm.
Need to change 3 of lift cylinder later on again and can save described step a, only implementation step b is to step f.
From as seen last, the invention enables whole lift cylinder to change and be operated in ground enforcement, eliminate safe hidden trouble, improved efficiency.
Claims (2)
1. plate blank weighing machine lifting cylinder changing method, plate blank weighing machine comprise mainly and it is characterized in that by the lift cylinder at crossbeam and suspension bracket two ends described replacing method is carried out according to following step:
A is at crossbeam and the outside, lift cylinder junction welding block;
B utilizes lift cylinder to promote crossbeam, cushion block on pad between plate blank weighing machine base and the block;
C sheds pressure, makes lift cylinder and crossbeam and suspension bracket be in lax connection status;
D throws off the pin between lift cylinder and suspension bracket and the crossbeam, changes lift cylinder;
E, the lift cylinder pressurization, the lifting crossbeam removes cushion block;
F sheds pressure, puts down lift cylinder.
2. plate blank weighing machine lifting cylinder changing method according to claim 1 is characterized in that the cushion block among the described step b is the steel cushion block, and thickness is not less than 25mm.
