Description
Technical Field
The utility model relates to a arresting gear technical field, concretely relates to cold-packed formula intelligence temperature display appearance backstop.
Background
When equipment such as an inclined conveyor, a bucket elevator, a winch, a large fan and a rotary kiln is used, a backstop is usually adopted to prevent the equipment from reversing when the final actuating mechanism cannot reverse due to unexpected power failure or transmission failure.
The fixed connection between the rotating shaft and the inner ring of the existing backstop is realized by adopting a key connection mode, the key groove can weaken the strength of the rotating shaft, the rotating shaft is easy to break under the condition of large load, and the key groove and the key of the key connection are usually arranged in the middle of the rotating shaft, so that the backstop is very inconvenient to install and disassemble.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that to the not enough of above-mentioned prior art, provide a cold-packed formula intelligence temperature display appearance backstop, can realize the quick installation of backstop, improve the installation effectiveness and save the labour.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a cold dress formula intelligence temperature display appearance holdback, includes outer lane, inner circle, pivot, the outer lane cup joints with the inner circle, the mounting hole that can supply the pivot installation is seted up to the inner circle, form the installation cavity between pivot and inner circle inner wall, make pivot and inner circle linkage, its characterized in that through setting up connecting device in the installation cavity: the connecting device is an expansion sleeve, the expansion sleeve is sleeved with the rotating shaft, the expansion sleeve, the inner ring and the rotating shaft are linked, and the expansion sleeve is fixedly connected with the inner ring through a locking piece.
The utility model has the characteristics as above: the expansion sleeve is used as a connecting device between the inner ring and the rotating shaft to replace key connection, and the rotating shaft cancels a key slot, thereby avoiding the situation that the rigidity of the rotating shaft is weakened and prolonging the service life of the rotating shaft; the expansion sleeve is arranged between the inner ring and the rotating shaft, so that the three are linked; only need can dismantle the tight cover of expanding out after unscrewing the retaining member during dismantlement, it is all very convenient to dismantle with the installation, has effectively improved backstop installation effectiveness and save labour, reduction in production cost.
The utility model discloses further setting is: the expansion sleeve comprises a conical boss and a connecting disc, the inner wall of the installation cavity of the inner ring is provided with a conical surface matched with the conical boss, the end face of the inner ring is provided with an installation groove matched with the connecting disc, and the connecting disc is fixedly connected with the installation groove through a locking bolt.
The utility model has the characteristics as above: the expansion sleeve generates huge holding force by the force from the conical surface and the rotating shaft, so that keyless connection between the inner ring and the rotating shaft is realized, and the rotating shaft, the expansion sleeve and the inner ring do not move relatively under the action of the expansion sleeve, so that synchronous linkage is realized; when the expansion sleeve bears load, the combination pressure of the expansion sleeve, the inner ring and the rotating shaft and the friction force generated therewith transmit torque and axial force, and when the expansion sleeve is overloaded, the expansion sleeve loses the coupling effect, so that the equipment can be protected from being damaged.
The utility model discloses further setting is: the temperature collector is arranged inside the outer ring, the intelligent temperature display instrument is arranged on the surface of the outer ring, and the temperature collector is connected with the intelligent temperature display instrument through a data transmission line.
The utility model has the characteristics as above: the temperature collector reflects the internal temperature change of the backstop on the intelligent temperature display instrument, the temperature rise condition of the backstop in operation is monitored in real time, the safety accident caused by failure of the backstop can be prevented in advance, and the safety performance of the backstop is improved.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
