Abstract
The utility model discloses a kind of linkage structure of Sling for lifting roller pinch liner plate, this linkage structure comprises steel sole plate and liner plate, described steel sole plate surface is interval with some dovetail grooves along its length, it is convex stupefied that the described liner plate back side is interval with the dovetail shaped mated with described dovetail groove some positions along its length, in some dovetail grooves of the described steel sole plate of the convex stupefied insertion of some dovetail shapeds of described liner plate.This linkage structure also comprises two rectangular pressing plates, described two rectangular pressing plates by bolt be located at described steel sole plate bi-side and against the bi-side of described liner plate.This structure overcomes the defect that conventional straps connects, and effectively avoids the damage of handling process breaker roll, improve the working life of liner plate, and liner plate is easy for installation, ensure that normal, the safety of roll lifting job are carried out.
Description
Technical field
The utility model relates to a kind of linkage structure of Sling for lifting roller pinch liner plate.
Background technique
Usual roll, in the operation process such as maintenance, installation, all needs to adopt suspender handling, and electronic Sling for lifting roller in use, just can carry out lifting job after being clamped by roll by pinch.Therefore, for avoiding pinch inner side surface and roll collide and rub, usually on the steel sole plate surface of pinch, liner plate being installed, directly being contacted with roll by liner plate, thus avoid handling process to damage roll.
As shown in Figure 1, steel sole plate 1 is provided with screw to the linkage structure of steel sole plate and liner plate, liner plate 2 is processed with bolt hole 21, and in adopting between steel sole plate 1 with liner plate 2, hexagonal countersunk screw 3 is connected, and makes the plane of bolt 3 lower than the plane of liner plate 2.Usually in actual applications, the thick of liner plate 2 is 10mm, and bolt hole 21 degree of depth is 5mm, namely allows liner plate 2 wear-thickness to be 5mm.At the scene in operation, due to the frequent handling of roll, liner plate 2 constantly collide with roller surface and rubs, cause liner plate 2 continuous wear and tear thinning.When liner plate 2 may wear to the thickness of 5mm, bolt 3 will be caused to expose, now, if fixture continues to use, bolt 3 will rub with roll, thus causes roll to abrade, and needs breaker roll again to repair, and causes larger economic loss.In addition, because fixture uses comparatively frequent, therefore liner plate 2 replacement frequency is higher, and bolt 3 and screw are through repeatedly removing and installing, and easily causes the phenomenon of bolt 3 or the sliding tooth of screw, thus causes liner plate 2 can not normal mounting, affects the lifting job of roll.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of linkage structure of Sling for lifting roller pinch liner plate, this structure overcomes the defect that conventional straps connects, effectively avoid the damage of handling process breaker roll, improve the working life of liner plate, and liner plate is easy for installation, ensure that normal, the safety of roll lifting job are carried out.
For solving the problems of the technologies described above, the linkage structure of the utility model Sling for lifting roller pinch liner plate comprises steel sole plate and liner plate, described steel sole plate surface is interval with some dovetail grooves along its length, it is convex stupefied that the described liner plate back side is interval with the dovetail shaped mated with described dovetail groove some positions along its length, in some dovetail grooves of the described steel sole plate of the convex stupefied insertion of some dovetail shapeds of described liner plate; This linkage structure also comprises two rectangular pressing plates, described two rectangular pressing plates by bolt be located at described steel sole plate bi-side and against the bi-side of described liner plate.
Further, the degree of depth of described dovetail groove is 5mm, slot bottom width is 156mm, angle is 45o.
Further, described liner plate is multistage liner plate, and to be interval with three dovetail shapeds along its length convex stupefied every section of liner plate back side.
Further, described liner plate is nylon lining plate.
Because the linkage structure of the utility model Sling for lifting roller pinch liner plate have employed technique scheme, namely this linkage structure comprises steel sole plate and liner plate, described steel sole plate surface is interval with some dovetail grooves along its length, it is convex stupefied that the described liner plate back side is interval with the dovetail shaped mated with described dovetail groove some positions along its length, in some dovetail grooves of the described steel sole plate of the convex stupefied insertion of some dovetail shapeds of described liner plate.This structure overcomes the defect that conventional straps connects, and effectively avoids the damage of handling process breaker roll, improve the working life of liner plate, and liner plate is easy for installation, ensure that normal, the safety of roll lifting job are carried out.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is traditional steel sole plate of Sling for lifting roller pinch and the connection diagram of liner plate;
Fig. 2 is the linkage structure schematic diagram of the utility model Sling for lifting roller pinch liner plate.
Embodiment
Embodiment 1 as shown in Figure 2, the linkage structure of the utility model Sling for lifting roller pinch liner plate comprises steel sole plate 1 and liner plate 2, described steel sole plate 1 surface is interval with some dovetail grooves 11 along its length, described liner plate 2 back side is interval with the dovetail shaped convex stupefied 22 mated with described dovetail groove 11 some positions along its length, and some dovetail shapeds convex stupefied 22 of described liner plate 2 insert in some dovetail grooves 11 of described steel sole plate 1; This linkage structure also comprises two rectangular pressing plates 4, described two rectangular pressing plates 4 by bolt 41 be located at described steel sole plate 1 bi-side and against the bi-side of described liner plate 2.Rectangular pressing plate can effectively prevent liner plate in use side direction skid off dovetail groove, thus ensure liner plate and the reliability be connected between steel sole plate.
Preferably, the degree of depth of described dovetail groove 11 is 5mm, slot bottom width is 156mm, angle is 45o.
Preferably, described liner plate 2 can adopt multistage liner plate, and every section of liner plate back side is interval with three dovetail shapeds convex stupefied 22 along its length.In actual using process, Sling for lifting roller handling list props up more than the frequency of handling a pair roller 3 times of the frequency of roll, make liner plate different in the degree of wear of length direction, the liner plate bottom wearing and tearing of obvious clamping single roll are faster, therefore the multistage liner plate of piecemeal is adopted can to change with regard to the monolithic bottom liner plate of wearing and tearing, more reasonable than liner plate integral replacing, thus save cost.
Preferably, described liner plate 2 is nylon lining plates.Nylon lining plate can carry out flexible clamping in breaker roll surface, avoids the damage of roller surface.
This linkage structure has abandoned the bolt connecting mode of steel sole plate and liner plate, thus liner plate can be may wear to greatest extent, improves the working life of liner plate, avoids causing bolt to expose because of a small amount of wearing and tearing of liner plate, thus the problem of scratch roll; Simultaneously liner plate is once wear extent is too large, when needing to change, without the need to integral replacing, only need change the liner plate of most easily-worn position, greatly save liner plate cost.In addition, this linkage structure solves the problem causing bolt or the sliding tooth of screw because frequently changing liner plate, facilitates the connection of steel sole plate and liner plate, only needs the installation that convex for dovetail shaped stupefied insertion dovetail groove can be completed liner plate.
