Abstract
The utility model discloses a winch and rotary table detachable hydraulic control device, relates to a mobile crane hydraulic system, and solves the technical problem that a hydraulic motor can be damaged after a winch and a rotary table of a crane are detached. A hydraulic pump and an oil tank are installed on the rotary table portion, and the hydraulic motor is installed on the winch portion; an overflow unit composed of an overflow valve and an oil overflow collecting bottle is added at a case return opening of the hydraulic motor, an inlet of the overflow valve is connected with the case return opening of the hydraulic motor through a pipeline, and an outlet of the overflow valve is connected with the oil overflow collecting bottle; and a case drain pipe of the hydraulic pump is connected with a case drain pipe of the hydraulic motor through a quick coupling, and leaked hydraulic oil is communicated with the oil tank. The hydraulic control device is applied to the mobile crane equipment, not only transport of the winch and the rotary table after detachment can be achieved, but also a shaft seal ring of the hydraulic motor is prevented from being damaged.
Description
Technical field
The utility model relates to the Control in Hydraulic Rotation System of movable crane, particularly mobile crane winding and turntable two parts detouchable hydraulic control device.
Background technology
For general HM Hydraulic Motor, be subjected to the impact of rotating speed and the housing draining pressure of motor the service life of Simmer ring.In order to guarantee the service life of Simmer ring, it requires the average lasting housing draining pressure under operating temperature can not surpass 3bar, allows in short-term the absolute pressure peak value to be up to 10bar.The frequency that peak pressure occurs is higher, and the service life of Simmer ring is shorter.
At present, large-scale mobile weight-lifting equipment (such as crawler crane, all terrain crane etc.) is because in the requirement of when transition domestic shipping weight, elevator and turntable two parts need to be split to transport.Elevator is after fractionation, and the housing oil return line of HM Hydraulic Motor separates with the complete machine oil return line, thereby forms an enclosure space, and the fluid in this space can expand along with the rising of ambient temperature, causes housing oil return line pressure to raise.Under extreme situation, this pressure can allow housing draining pressure considerably beyond HM Hydraulic Motor, can cause damage to the Simmer ring of HM Hydraulic Motor.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of elevator and turntable detachable hydraulic control device are provided, after solving the elevator of present movable crane and turntable and splitting, and the technical matters that can cause HM Hydraulic Motor to damage.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of elevator and turntable detachable hydraulic control device, comprise: Hydraulic Pump, fuel tank and HM Hydraulic Motor, it is characterized in that: described Hydraulic Pump, fuel tank are installed in the turntable part, and the case drain line road of Hydraulic Pump links to each other with fuel tank, and described HM Hydraulic Motor is installed in the elevator part; Housing return opening in described HM Hydraulic Motor increases the overflow device that is made of by pass valve and oil spilling receiving flask, and the entrance of by pass valve is connected with the housing return opening pipeline of HM Hydraulic Motor, and the outlet of by pass valve is connected with the oil spilling receiving flask; With quick coupling with the case drain line road of described Hydraulic Pump be connected the case drain line road of HM Hydraulic Motor and connect, the leakage fluid force feed is communicated with described fuel tank.
Further, the oil pressure relief of described by pass valve is set as the top pressure that described hydraulic motor casing allows, the setting pressure of described by pass valve will be higher than the top pressure of oil return line under in working order.
The utility model compared with prior art has the following advantages and beneficial effect:
The utility model is owing to described Hydraulic Pump, fuel tank are placed in the turntable part, and described HM Hydraulic Motor is installed in the elevator part; Housing return opening in described HM Hydraulic Motor has increased overflow device, and therefore, when car load was worked, the hydraulic motor casing oil return line can be communicated with fuel tank by quick coupling; When elevator is in disassembly status, if the oil liquid pressure in the pipeline surpasses the setting value of by pass valve, by pass valve is opened, and unnecessary fluid enters into the oil spilling receiving flask by by pass valve, guarantee that hydraulic motor casing pressure is no more than authorized pressure, thereby prevented that HM Hydraulic Motor is damaged.The utility model is used for Mobile hoisting equipment, can realize not only that elevator and turntable two parts split to transport, and can prevent that the Simmer ring of HM Hydraulic Motor from can not cause damage.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The utility model is further described by preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 1, a kind of elevator and turntable detachable hydraulic control device comprise: Hydraulic Pump 2, fuel tank 3 and HM Hydraulic Motor 5, and described Hydraulic Pump 2, fuel tank 3 are installed in turntable part A, the case drain line road of Hydraulic Pump 2 links to each other with fuel tank 3, and described HM Hydraulic Motor 5 is installed in elevator part B; Housing return opening in described HM Hydraulic Motor 5 increases the overflow device that is made of by pass valve 6 and oil spilling receiving flask 4, and the entrance P of by pass valve 6 is connected with the housing oil return inlet T pipeline of HM Hydraulic Motor 5, and the outlet T of by pass valve 6 is connected with oil spilling receiving flask 4; The case drain line road of being connected with HM Hydraulic Motor in the case drain line road of Hydraulic Pump 2 with quick coupling 1 connects, and the leakage fluid force feed is communicated with fuel tank 3.
The oil pressure relief of by pass valve 6 is set as the top pressure that HM Hydraulic Motor 5 housings allow, when car load is worked, HM Hydraulic Motor 5 housing oil return lines are communicated with fuel tank 3 by quick coupling 1, HM Hydraulic Motor 5 housing draining pressure are the loss of pressure of oil return line, and this pressure generally can not surpass the average lasting housing draining pressure of HM Hydraulic Motor 5 under operating temperature.In order to guarantee that HM Hydraulic Motor 5 housing leakage fluid force feeds can be from by pass valve 6 overflows in when normal operation, the setting pressure of by pass valve 6 will be higher than the top pressure of oil return line under in working order.
When elevator part B is in disassembly status, HM Hydraulic Motor 5 housing oil return lines are in closed state, fluid in the pipeline expands along with the rising of ambient temperature, pressure increases, when pressure surpasses the setting pressure (top pressure that hydraulic motor casing allows) of by pass valve 6, by pass valve 6 is opened, unnecessary fluid enters into oil spilling receiving flask 4 by by pass valve 6, thereby guaranteed that hydraulic motor casing draining pressure is not higher than the top pressure that housing allows, prevented that the sealing member that causes because of the hydraulic motor casing hypertonia from damaging.When the hydraulic pressure oil mass in the oil spilling receiving flask 4 reaches certain value, empty the oil spilling receiving flask, prevent that fluid from overflowing environment.
