Abstract

The invention relates to a cooling structure of a hydraulic system of a loading and unloading crane of a bulk carrier. The cooling structure comprises a pedestal. A movable tower is installed on the upper end of the pedestal through a slewing bearing. A swing drive hydraulic motor is arranged between the movable tower and the pedestal. A luffing winch and a lifting winch which are respectively driven by a luffing hydraulic motor and a lifting hydraulic motor are arranged on the movable tower. A heat exchange plate is disposed on the top of the movable tower. Two ends of a channel of the heat exchange plate are connected in series in a hydraulic pipeline of a hydraulic station. A temperature sensor is disposed inside a hydraulic oil tank of the hydraulic station. One side of the heat exchange plate is provided with a cooling fan driven by a motor. The motor and the temperature sensor both access to a control system. The temperature of hydraulic oil is monitored in real time by the temperature sensor, and the control system is used to control the motor so as to drive the cooling fan, thus leading to forced cooling of the hydraulic oil which passes through the heat exchange plate. By the adoption of the cooling structure, it is ensured that the temperature of the hydraulic oil in the hydraulic system is within the normal work range, and hydraulic oil viscosity reduction which influences normal operation of the hydraulic system is avoided.

Description

Bulge carrier loading and unloading loop wheel machine hydraulic efficiency pressure system cooling structure
Technical field
The present invention relates to a kind of high empty wagons, particularly a kind of close-coupled high-altitude chassis expands bridge system.
Background technology
Bulge carrier is that bulk carrier is called for short, and is to be used for transporting the goods that does not add wrapping specially, like coal, ore, timber, livestock, cereal etc.Bulge carrier loading and unloading loop wheel machine is used for the loading and unloading of bulk goods Cargo On Deck; It comprises that rotating relatively pedestal, movable body of the tower can take place in installation; Be provided with revolution between movable body of the tower and the pedestal and drive HM Hydraulic Motor; Be provided with on the movable body of the tower respectively by the span winch of the luffing HM Hydraulic Motor and the fluid motor-driven that hoists with hoist winch, revolution drives HM Hydraulic Motor, luffing HM Hydraulic Motor and the HM Hydraulic Motor that hoists by the Hydraulic Station feed flow.Because Hydraulic Station needs simultaneously to three HM Hydraulic Motor feed flows during work, and power is bigger, the hydraulic oil temperature rise is very fast, reduces hydraulic oil viscosity easily, and leaking increases, and has reduced Volumetric efficiency, even has influenced the normal operation of operating mechanism.
Summary of the invention
The technical matters that the present invention will solve provides a kind of bulge carrier loading and unloading loop wheel machine hydraulic efficiency pressure system cooling structure that can when hydraulic fluid temperature is higher, carry out forced cooling.
For solving the problems of the technologies described above; Technical scheme of the present invention is: a kind of bulge carrier loading and unloading loop wheel machine hydraulic efficiency pressure system cooling structure; Comprise the pedestal that is installed on the bulk goods wheel deck, said pedestal upper end is equipped with movable body of the tower through pivoting support, is provided with revolution between said movable body of the tower and the pedestal and drives HM Hydraulic Motor; Be provided with on the movable body of the tower respectively by luffing HM Hydraulic Motor and the span winch of the fluid motor-driven that hoists and the winch that hoists; Said revolution driving HM Hydraulic Motor, the luffing HM Hydraulic Motor and the HM Hydraulic Motor that hoists are by the Hydraulic Station feed flow, and its innovative point is: the top of said movable body of the tower is provided with heat exchanger plates, and the runner two ends of said heat exchanger plates are serially connected in the hydraulic tubing of Hydraulic Station; In the hydraulic reservoir of said Hydraulic Station temperature sensor is set, a side of heat exchanger plates is provided with by motor-driven cooling fan; The equal access control system of said motor and temperature sensor.
The invention has the advantages that: temperature sensor is monitored hydraulic fluid temperature in real time, and is transferred to control system.In the time of in hydraulic oil temperature is in normal range, hydraulic oil is only through heat exchanger plates the time, through the radiating fin and the extraneous heat exchange cooling of heat exchanger plates; When control system detected the oil temperature above setting value, the control motor was opened and is driven cooling fan, thereby the hydraulic oil through heat exchanger plates is carried out forced cooling.The hydraulic oil temperature of guaranteeing hydraulic efficiency pressure system is in the normal operating range, avoids hydraulic oil viscosity decline to influence hydraulic efficiency pressure system and moves normally.
Description of drawings
Fig. 1 is bulge carrier loading and unloading loop wheel machine hydraulic efficiency pressure system cooling structure scheme drawing of the present invention.
The specific embodiment
As shown in Figure 1, comprise pedestal 1, pivoting support 2, movable body of the tower 3, rotary fluid motor 4, luffing HM Hydraulic Motor 5, the HM Hydraulic Motor 6 that hoists, jib 7, span winch steel rope group 8, the winch cable group 9 that hoists, Hydraulic Station 10, heat exchanger plates 11, cooling fan 12.
The upper end of said base 1 is equipped with movable body of the tower 3 through pivoting support 2; Be provided with the revolution driving HM Hydraulic Motor 4 that driving activity body of the tower 3 rotates between movable body of the tower 3 and the pedestal 1 on pedestal 1, the span winch and the winch that hoists that are driven by the luffing HM Hydraulic Motor 5 and the HM Hydraulic Motor 6 that hoists respectively are set on the movable body of the tower 3.Bottom-hinged at movable body of the tower 3 has jib 7, and the span winch steel rope group 8 of mutually noninterfere and the winch cable group 9 that hoists are installed between the top of this jib 7 and movable body of the tower 3 tops.Wherein, revolution driving HM Hydraulic Motor 4, the luffing HM Hydraulic Motor 5 and the HM Hydraulic Motor 6 that hoists are by Hydraulic Station 10 feed flows.
Be provided with heat exchanger plates 11 on the top of movable body of the tower 3; Heat exchanger plates 11 is provided with radiating fin outward for copper pipeline; The runner two ends of heat exchanger plates 8 are serially connected in the hydraulic tubing of Hydraulic Station 10; In the hydraulic reservoir of Hydraulic Station 10 temperature sensor is set, a side of heat exchanger plates 11 is provided with the cooling fan 12 that is driven by motor 13.Temperature sensor and motor 13 equal access control systems.
Principle of work: temperature sensor is monitored hydraulic fluid temperature in real time, and is transferred to control system.In the time of in hydraulic oil temperature is in normal range, hydraulic oil is only through heat exchanger plates 11 time, through the radiating fin and the extraneous heat exchange cooling of heat exchanger plates 11; When control system detected the oil temperature above setting value, control motor 13 was opened and is driven cooling fan 12, thereby the hydraulic oil through heat exchanger plates 11 is carried out forced cooling.
