Abstract
The utility model discloses an oil-loss protecting device of a speed reducer of a bucket wheel stacker and reclaimer, comprising a main motor control circuit and a pressure relay arranged on an oil passage, by which an oil pump conveys oil to the speed reducer; and the pressure relay is connected with the main motor control circuit. In the utility model, the pressure relay is arranged on the oil passage, by which the oil pump conveys the oil to the speed reducer; and when the pressure of the oil liquid input in the speed reducer is reduced, a main motor of the speed reducer is controlled and driven to stop running by the pressure relay and the main motor control circuit, thus protecting the speed reducer; therefore, the oil-loss protecting device of the speed reducer of the bucket wheel stacker and reclaimer completely avoids the speed reducer from continuing to rotate and be abraded when in an oil loss state.
Description
Technical field
The utility model relates to a kind of bucket-wheel stacker reclaimer retarder fender guard, relates in particular to a kind of bucket-wheel stacker reclaimer retarder and loses the oil guard device.
Background technology
Bucket-wheel stacker reclaimer is heap, gets the rail mounted handling equipment of unification, and the heap that is used for ore is got.Have functions such as walking, jib rotation, pitching, machine endothelium tape running, bucket wheel rotation on the rail.Can carry out manually and material-taking on-site, windrow operation.
In the prior art; the lubricated pump fuel feed that adopts of the retarder of bucket-wheel stacker reclaimer; Oil pump electrical machinery control loop and the main electric motor loop that drives retarder be interconnected lock mutually; when Oil pump electrical machinery shuts down; the main motor that drives retarder is simultaneously out of service; in order to avoid retarder is losing long-time running under the oil condition, reach the purpose of protection.In real work; when Oil pump electrical machinery normally moves; and the oil pump of on-load is damaged; quit work, retarder is in the mistake oil condition, but since Oil pump electrical machinery also in normal operation; do not jump electric protection according to linkage relationship The whole control loop; the main motor that drives retarder causes retarder losing oepration at full load under the oil condition also in work, and is badly damaged until retarder.Given this, the transformation to the whole protecting loop is very urgent.
Summary of the invention
At the prior art above shortcomings; the main motor that the utility model provides a kind of pressure control according to the retarder inner fluid to drive retarder rotates or the bucket-wheel stacker reclaimer retarder that stops loses the oil guard device, adopts this device can avoid retarder to be in fully to lose oil condition and is damaged.
The bucket-wheel stacker reclaimer retarder that the utility model provides loses the oil guard device, comprises main motor control loop and is arranged on the pressure relay of oil pump on the oil circuit of retarder oil transportation, and described pressure relay is connected with main motor control loop.
The beneficial effects of the utility model: the utility model adopts and on the oil circuit of retarder oil transportation pressure relay is set at oil pump; when the oil liquid pressure in the input retarder reduces; main motor by pressure relay and main motor control loop controlling and driving retarder is out of service; thereby the protection retarder has been avoided retarder to be in fully losing oil condition and is rotated further and weares and teares.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
Accompanying drawing is a structural representation of the present utility model; as shown in the figure: the bucket-wheel stacker reclaimer retarder loses the oil guard device and comprises main motor control loop 1 and be arranged on the pressure relay 4 of oil pump 2 on the oil circuit of retarder 3 oil transportations that described pressure relay 4 is connected with main motor control loop 1.
Bucket-wheel stacker reclaimer often is in open work, and retarder and bonded assembly oil circuit thereof vibration simultaneously is severe, and pressure relay 4 has favorable protection and shock resistance.The internal piloting node and the main electric machine control protection loop 1 of pressure relay 4 is chain; when the oil liquid pressure in the input retarder 3 reduces; main motor 5 by pressure relay 4 and main motor control loop 1 controlling and driving retarder is out of service; thereby the protection retarder has been avoided retarder to be in fully losing oil condition and is rotated further and weares and teares.Package unit is reliable, has ensured the continuity of producing, and has reduced the repair and maintenance expense, has improved the service life of equipment, has also improved production efficiency simultaneously.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
Claims (1)
1. a bucket-wheel stacker reclaimer retarder loses the oil guard device; comprise main motor control loop (1); it is characterized in that: also comprise being arranged on the pressure relay (4) of oil pump (2) on the oil circuit of retarder (3) oil transportation, described pressure relay (4) is connected with main motor control loop (1).
