The automatic feeding device has the advantages of low input cost, visual and obvious effect, reduction of manpower use, reduction of work rhythm of workers and improvement of work efficiency.
Description
Technical Field
The utility model relates to a large-scale cylindrical grinder grinding wheel hoist and mount change technical field in the iron and steel trade, in particular to emery wheel stone tongs.
Background
A grinding wheel of a large cylindrical grinding machine is generally assembled with a special chuck for use in use, according to the process flow of dismounting and mounting the grinding wheel, the grinding wheel to be replaced is hung from the grinding machine by a special chuck lifting appliance, a normal chuck and an old grinding wheel assembly are horizontally placed, a special tool is used for dismounting a chuck clamping device on the grinding wheel, the old grinding wheel is lifted out of the chuck by manpower after the chuck clamping device is completely dismounted, a spare new grinding wheel is lifted up and aligned to be mounted in the chuck, the weight of the old grinding wheel to be dismounted is about 35kg after the old grinding wheel to be dismounted is used, the weight of the brand new grinding wheel to be mounted is about 80kg, the old grinding wheel can be independently dismounted by one person for good physical quality, but a large amount of manpower is required for mounting the new grinding wheel, the fit clearance between the grinding wheel chuck and the grinding wheel is very small, and the smooth mounting can be realized only by ensuring the horizontality of the grinding wheel, the assembler is at least 2 or more individuals.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a when changing large-scale cylindrical grinder grinding wheel, effectually carry out the suspension clamp installation to the grinding wheel, reduce the use of manpower, improve work efficiency's emery wheel stone tongs.
The utility model discloses a solution is such:
a grinding wheel hoisting clamp comprises at least three hoisting tool assemblies, wherein the lower end of a base of each hoisting tool assembly is provided with a support for supporting a grinding wheel, and the upper end of each hoisting tool assembly is hinged with the middle of a pressing plate, so that the pressing plate forms a swing rod structure; the upper end of the pressing plate is connected with the lifting rope, the lower end of the pressing plate is a pressing end, and clamping force formed between the support of the base and the pressing end of the lower end of the pressing plate acts on two sides of the grinding wheel respectively to clamp the grinding wheel.
The more specific technical scheme also comprises the following steps: the lifting ropes respectively connected with each lifting appliance component are the same in length, one end of each lifting rope is connected with the upper end of the pressing plate, and the other ends of the lifting ropes are connected with the lifting hook after being converged into a connection point.
The utility model has the advantages that the input cost is low, and the effect is directly perceived obvious, reduces the manpower and uses, slows down staff's work rhythm, has improved work efficiency.
Drawings
Fig. 1 is a schematic view of the usage state of the present invention.
Fig. 2 is a schematic structural diagram of the present invention.
The parts of the drawings are detailed as follows: the grinding wheel grinding device comprises a cantilever crane hook 1, a grinding wheel 2, a grinding wheel chuck 3, a lifting appliance component 4, a pressing plate 5, a nut 6, a bolt 7, a base 8 and a lifting rope 9.
Detailed Description
As shown in fig. 1 and 2, in the present embodiment, three lifting tool assemblies 4 and corresponding lifting ropes 9 are adopted, a support for supporting a grinding wheel is arranged at the lower end of a base 8 of each lifting tool assembly 4, and the upper end of each lifting tool assembly is hinged to the middle of a pressing plate 5 through a nut 6 and a bolt 7, so that the pressing plate 5 forms a swing rod structure swinging around the bolt 7; the upper end of the pressing plate 5 is connected with the lifting rope 9, the lower end of the pressing plate is a pressing end, and clamping force formed between the support of the base 8 and the pressing end at the lower end of the pressing plate 5 acts on two sides of the grinding wheel respectively to clamp the grinding wheel.
The lifting ropes 9 respectively connected with each lifting appliance component 4 are the same in length, one ends of the lifting ropes 9 are connected with the upper end of the pressing plate 5, and the other ends of the lifting ropes 9 are connected with the lifting hooks after being converged into a connection point, so that the horizontality of the grinding wheel and the chuck plate is guaranteed.
According to the requirements of a working use site, the actual parameters of the grinding wheel used by the grinding machine are determined, the C-shaped clamping hanger with the matched thickness is manufactured according to the thickness, the diameter and the weight of the grinding wheel, the pressing lip of the clamping hanger can be designed in multiple angles according to the requirements, and the clamping condition of the grinding wheel with multiple types of one clamp is met.
The working process of the embodiment is as follows: the three lifting appliances of the lifting appliance group are uniformly clamped on the grinding wheel sheet to keep the balance and the levelness of the grinding wheel sheet, the lower end of the base 8 supports the bottom surface of the grinding wheel, the lower end of the pressing plate 5 presses the top surface of the grinding wheel, the lifting ring of the lifting appliance group is hung in the lifting hook by using the cantilever lifting hook to be stably lifted, and the clamp is stretched under the gravity action of the grinding wheel, so that the grinding wheel is clamped by a clamping force formed between the support of the base 8 and the pressing end at the lower.
