Technical Field

The utility model relates to the technical field of crane rotary motors, in particular to a crane rotary motor valve bank.

Background

The crane rotary motor is a driving piece used for controlling the crane to reciprocate on the crane, and works and stands still through the related valve group;

however, when the existing crane rotary motor is used, the valve group arranged on the existing crane rotary motor is single, and the forward rotation, the reverse rotation and the rest of the motor cannot be rapidly controlled, so that the overall fuel consumption is higher, the cost is further increased, and therefore the crane rotary motor valve group is provided, and the problems are solved.

Disclosure of Invention

The utility model aims to provide a crane rotary motor valve group, which solves the problems that when the existing crane rotary motor is used, the valve group arranged on the existing crane rotary motor is single, and the forward rotation, the reverse rotation and the rest of the motor cannot be rapidly controlled, so that the overall oil consumption is higher, and the cost is further increased.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the crane rotary motor valve group comprises a valve block, a first pressure measuring port and a second pressure measuring port are formed in the top of the valve block, a first balance valve and a second balance valve are respectively arranged on two sides of the valve block, and an oil outlet, an oil inlet and an oil return port are formed in the surface of the valve block.

Preferably, as the crane rotary motor valve group of the present utility model, a shuttle valve is mounted on the surface of the valve block.

Preferably, as the crane rotary motor valve group, an oil pressure reversing valve is arranged at the top of the valve block.

Preferably, the crane rotary motor valve group is provided with a single-action brake cylinder interface on the surface of the valve block.

Compared with the prior art, the utility model has the following beneficial effects:

the device mainly controls three states of forward rotation, reverse rotation and static state of a motor by arranging the valve block, the first balance valve, the oil outlet, the single-acting brake cylinder interface, the shuttle valve, the oil inlet, the oil return port, the pressure reversing valve, the first pressure measuring port, the second pressure measuring port and the second balance valve. Under the conventional condition, the motor is in a static state, the brake cylinder enables the motor to be in a braking state, the load on the motor is in a static holding state by the first balance valve and the second balance valve, and when oil inlet and oil outlet are provided, the pressure reaches the set pressure of the pressure reversing valve at first, the brake is released, and the motor rotates.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, a crane rotary motor valve group comprises a valve block 1, wherein a first pressure measuring port 9 and a second pressure measuring port 10 are arranged at the top of the valve block 1, a first balance valve 2 and a second balance valve 11 are respectively arranged at two sides of the valve block 1, and an oil outlet 3, an oil inlet 6 and an oil return port 7 are arranged on the surface of the valve block 1.

As a technical optimization scheme of the utility model, further, a shuttle valve 5 is arranged on the surface of the valve block 1, the shuttle valve 5 belongs to a straight line Cheng Famen, and is a valve with a valve body and an actuator integrated into a whole. Its advantage is small, simple to operate, in addition the particularity of inside piston structure for the medium pressure hardly has more resistance to the piston to disturb, thereby realizes fast switch, the outstanding quality that the pressure loss is little.

As a technical optimization scheme of the utility model, further, the oil pressure reversing valve 8 is arranged at the top of the valve block 1, and the pressure of high-pressure oil can be limited through the oil pressure reversing valve 8.

As a technical optimization scheme of the utility model, further, the surface of the valve block 1 is provided with a single-acting brake cylinder interface 4, and a brake cylinder which can be connected through the single-acting brake cylinder interface 4 is further used for enabling the motor to be in a braking state.

Working principle:

before use, the safety of each structure of the device is checked firstly, when high-pressure oil enters from the oil outlet 3, the high-pressure oil enters one side of the motor through the second balance valve 11, meanwhile, the oil at the oil outlet 3 enters the pressure reversing valve 8 through the shuttle valve 5, the motor is in a braking state by the brake cylinder connected with the single-action brake cylinder interface 4 before the pressure reversing valve 8 is opened, and the first balance valve 2 and the second balance valve 11 have a load maintaining function. When the pressure of the high-pressure oil entering the pressure reversing valve 8 reaches the set pressure of the pressure reversing valve 8, the high-pressure oil passes through the single-acting brake cylinder interface 4 to release the brake, and meanwhile, the high-pressure oil passing through the second balance valve 11 rotates the motor, and the motor returns through the second balance valve 11 and returns through the return port 7. Whereas high pressure oil enters through the oil inlet 6 and vice versa.
