Abstract
The utility model relates to hoisting devices, particularly to a roller table hoisting device for mounting of roller tables, which is a special replacement device for layer flow roller tables and heat transport roller tables in hot-rolling mills. The device comprises a hoisting cross beam; a hand chain hoist is connected to one end of the hoisting cross beam, and a counterweight body is connected to the other end thereof; and a hoisting hole is formed above the end of the hoisting cross beam where the counterweight body is connected. The hoisting cross beam and the counterweight body can form an integrated structure; and a plurality of balancing weights can be connected to the counterweight body as required. The utility model has the advantages that the roller table hoisting device can hoist a roller table in place directly and adopts a traveling crane for hoisting instead of the original hand chain hoist, thereby eliminating the potential safety hazards and greatly improving the working efficiency.
Description
Technical field
The utility model relates to the suspension apparatus class, specifically refers to a kind of roller-way hanging apparatus that roller-way is installed, and is applicable to as the specialty of hot rolling mill laminar flow roller-way, hot rollgang changing device more.
Background technology
Cold roller fault happens occasionally in the roller-way of thermal output roller-way, causes the roller needs constantly to be changed.Because interior cold roller is in convexity detector scope, the space is narrow and small, when day, periodical repair are changed roller or repairing replacing roller, driving or loop wheel machine all can not directly hang, send roller, rely on traditional manual indigenous method fully, promptly pass with many groups chain block and connect, in general changing a roller required time is about 495 minutes, and inefficiency, labour intensity be big, exist potential safety hazard.
As shown in Figure 1, interior cold roller is below profile gauge, the profile gauge total length reaches 9 meters, roll surface only has about 1.5 meters to the distance of profile gauge, the space is very narrow and small, travelling crane hook below can not directly putting in profile gauge hung out roller when roller was changed, and had only employing nine groups of chain blocks as shown in Figure 1 to pass the methods that connect in the prior art, the roller transmission is delivered to profile gauge framework external application driving hangs out.
The problem that this roll-changing method exists mainly contains:
1, owing to adopt many group chain blocks, the instrument that needs is many, and the workmen needs 10 people at least, and concentrates on the space construction of 1.5 meters of 9 meters X.
2, the manual biography connects lifting, exists unhook, Slip Hook, object landing potential safety hazard such as hurt sb.'s feelings.
3, change a roller and need about 490 minutes, only when periodical repair (16 hours), could arrange to change, change the untimely fault rate height that causes.
4, break profile gauge equipment easily in the roller lifting.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, a kind of roller-way hanging apparatus is provided, steel rope is firmly tied up roller-way,, cooperate driving can realize that the safety of roller-way installs handling again with the steel rope of slinging of the chain block on the roller-way hanging apparatus.
The utility model purpose realizes being finished by following technical scheme:
A kind of roller-way hanging apparatus comprises a lifting crossbeam, and an end of lifting crossbeam is connected with chain block, and the lifting crossbeam other end is connected with balance weight body, and described lifting crossbeam top position offers hole for hoist.
Above-mentioned lifting crossbeam and balance weight body are structure as a whole;
Be connected and installed with some clump weights on the above-mentioned balance weight body, bolt is connected between balance weight body and the clump weight;
Above-mentioned hole for hoist is at least two, and chain block is at least one.
The utility model has the advantages that the utility model roller-way hanging apparatus can directly put the roller-way lifting in place, avoid original chain block to pass and connect, directly, eliminate safe hidden trouble, improve operating efficiency greatly with the driving lifting.
Description of drawings
Fig. 1 is a prior art hanging apparatus structural representation;
Fig. 2 is the utility model apparatus structure scheme drawing;
Fig. 3 is an A-A cutaway view among Fig. 2.
The specific embodiment
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that the understanding of technical personnel of the same trade:
When safeguarding that roller is changed in replacing or repairing, driving or loop wheel machine all can not directly hang, send roller, rely on traditional manual indigenous method fully, promptly pass with many groups chain block to connect, as shown in Figure 1.Roller required time of general replacement is very long, and work efficiency is low, labour intensity is big, exist cooresponding potential safety hazard.
Be head it off, the utility model has been made a roller-way hanging apparatus that is used in particular for carrying roller-way, and this device can cooperate travelling crane hook carrying roller-way, and its structure as shown in Figure 2.The roller-way hanging apparatus mainly comprises lifting crossbeam 6, balance weight body 7, chain block 4 etc. in the present embodiment.One end of lifting crossbeam 6 is connected and installed with two chain blocks 4, and lifting crossbeam 6 other ends are connected with balance weight body 7, and lifting crossbeam 4 tops offer hole for hoist 9, and hole for hoist 9 is at least two.
Wherein, lifting crossbeam 6 can be structure as a whole with balance weight body 7.Be to regulate weight, but the some clump weights 10 of connection on the balance weight body 7 are captiveed joint by bolt 8 between balance weight body 7 and the clump weight 10, as shown in Figure 3.For making roller-way hanging apparatus two ends balance, can realize by regulating the installation that increases or reduce clump weight 10.
When using the utility model roller-way hanging apparatus, must guarantee dead halt after, confirming that the three parts lists can.Carry out according to following steps then:
The first step: flipper guide and move to other position of roller-way or hang out on the dismounting roller-way;
Second step: remove roller-way follower bolt and drier oil pipe, and the electric wire of motor;
The 3rd step: with driving or loop wheel machine suspender is sling, chain block one end hangs on the hook of suspender counterweight, an end hang over drive a vehicle or the hook of loop wheel machine on, with chain block with the suspender leveling;
The 4th step: the roller that will prepare lifting is tied up in the middle of the body of roll firmly with steel rope;
The 5th step: suspender is hung the roller steel rope on the hook of suspender above the effect of driving a vehicle is displaced downwardly to roller, slowly looses one's grip and draws cucurbit to soar and the suspender level up to roller, then, utilizes driving that roller is hung out, and is put into assigned address;
The 6th step: the greasy dirt and the dust of cleaning roller-way frame and base plate, coincide when guaranteeing roller and rack;
The 7th step: hang over admittedly on the suspender hook fastening with rope coil in the middle of the body of roll of preparing to reach the standard grade, roller is sling and with chain block the suspender leveling;
The 8th step: driving hangs in the profile gauge below with it, and the workmen slowly falls into roller the groove of roller-way underframe in the roller both sides, guarantees to install steadily;
The 9th step: return the electric wire of dress drier oil pipe, motor, flipper guide also guarantees certain setting accuracy.
