Description
Technical field
The utility model relates to technical field of coal mine equipment, specifically a kind of bearing mounting/dismounting device.
Background technology
Coal preparation plant is due to factors such as mine output is large, atures of coal, and Pulp pump bearing loss is comparatively large, if by traditional hot drawing bearing method, not only waste resource, used time longer, contaminated environment, and safety also can not get ensureing.The maintenance task burdensome of machine maintenance team every day, if by traditional hot drawing bearing method, will take their most working time, have a strong impact on normal production.
Summary of the invention
The purpose of this utility model is to solve above-mentioned problems of the prior art, and provides a kind of bearing mounting/dismounting device.
The utility model is achieved by the following technical solution:
A kind of bearing mounting/dismounting device, comprises bracing frame, positioning disk, top board, jack and electric block; Wherein, the bottom of bracing frame is provided with base, position bracing frame being positioned at middle part is fixed with the first brace rod, is positioned at the position of bottom and is fixed with the second brace rod, and the top of bracing frame offers the different locating hole of some height, is fitted with bolt in locating hole; Positioning disk is the disk body offering central through hole, and positioning disk to be placed in bracing frame and to support and is positioned on the first brace rod or the second brace rod; The end face of top board is connected with electric block, bottom surface is connected with jack, and top board slip is inserted into the top section of bracing frame and realizes altitude location by locating hole and bolt.
The course of work of the utility model bearing mounting/dismounting device is as follows:
1) dismounting of bearing: positioning disk is positioned on the first brace rod, axle is vertically put into positioning disk central through hole with fixed main shaft, with electric block top board sling and be inserted in bracing frame, with bolt, top board is fixed on correct position, with electric block, top board is strained, main shaft top will be placed on bottom jack, top board is withstood on top, manually slowly press jack, in time hearing the sound that bearing and main shaft depart from, continue gently to press jack, until bearing is separated completely with main shaft, namely complete the dismounting of bearing.
2) installation of bearing: positioning disk is positioned on the second brace rod, axle is vertically put into positioning disk central through hole with fixed main shaft, with electric block top board sling and be inserted in bracing frame, with bolt, top board is fixed on correct position, with electric block, top board is strained, will be placed on base bearing bottom jack, top board is withstood at top, manually slowly press jack, slowly bearing is packed into main shaft with the pressure of jack, till putting into main shaft completely.Pay special attention to main shaft two ends to be polished flat before installation bearing, bearing and main shaft should remain on same center line.
Huge effect has been played after the utility model bearing mounting/dismounting device comes into operation, originally the artificial a set of bearing of dismounting needs 48 hours, to use after replacer time shorten to 1 hour, effect improves 48 times, need 5 individual calculus by a set of bearing of dismounting, use a set of bearing of replacer dismounting to save cost of labor 1500 yuan.After have employed replacer, not only significantly reduce the labour intensity of employee, improve operating efficiency, decrease the repair time, strive for the most of the time for enterprise normally produces, also avoid manpower dismounting bearing and easily cause this phenomenon of bearing damage, improve the installation effect of bearing, the number of times that single cover pump year changes bearing is reduced to once by three times, and coal preparation plant's size pump about has 30 multiple stage, year saving bearing more than 60 overlaps, and material is made into and originally reduces 18000 yuan.
Simple, easy to operate, the flexible property of the utility model bearing mounting/dismounting device structure is strong, supports, with positioning disk fixed main shaft with bracing frame, top board is fixed with bolt, carry out the disassemble and assemble work of bearing with jack and electric block, decrease the working strength of workman, improve operating efficiency.
