Abstract
The utility model discloses a kind of winch balance cock with flow regulating valve, it relates to the technical field of engineering machinery such as man-riding winch, and it comprises valve block, balance cock, flow regulating valve and check valve; Balance cock is arranged on the side on valve block top, and the opposite side on valve block top is provided with check valve, and the rear side of valve block is provided with flow regulating valve.Its novel structure, improves the safety performance of winch, can detect the deceleration and stopping performance of winch brake, can get rid of the potential safety hazard in winch use procedure, provides technical guarantee for winch is used for manned operation.
Description
Technical field
The utility model relates to a kind of winch balance cock with flow regulating valve, belongs to the technical field of engineering machinery such as man-riding winch.
Background technology
In order to the safety problem of load in the process that solves winch rope closing or put rope, winch maker takes arrangement brake device and balance cock to ensure the normal work of winch usually.
Can the performance of drg be most important for winch performance, need accurately its brake torque of test reach requirement.Winch rise load time, utilize the drg of winch self and balance cock load to be mentioned smoothly and to land, though lose hydraulic power also can make load hang hold.But when losing hydraulic power, payload security but cannot decline by the balance cock of traditional winch accurately.
Summary of the invention
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of winch balance cock with flow regulating valve.
A kind of winch balance cock with flow regulating valve of the present utility model, it comprises valve block, balance cock, flow regulating valve and check valve; Balance cock is arranged on the side on valve block top, and the opposite side on valve block top is provided with check valve, and the rear side of valve block is provided with flow regulating valve.
The beneficial effects of the utility model are: its novel structure, improve the safety performance of winch, can detect the deceleration and stopping performance of winch brake, can get rid of the potential safety hazard in winch use procedure, provide technical guarantee for winch is used for manned operation.
accompanying drawing illustrates:
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is structural representation of the present utility model,
Fig. 2 is left view of the present utility model,
Fig. 3 is birds-eye view of the present utility model,
Fig. 4 is upward view of the present utility model,
Fig. 5 is back view of the present utility model.
In figure: 1-valve block; 2-balance cock; 3-flow regulating valve; 4-check valve.
detailed description of the invention:
For making the purpose of this utility model, technical scheme and advantage clearly understand, below by the specific embodiment shown in accompanying drawing, the utility model is described.But should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
As Figure 1-5, this detailed description of the invention by the following technical solutions: it comprises valve block 1, balance cock 2, flow regulating valve 3 and check valve 4; Balance cock 2 is arranged on the side on valve block 1 top, and the opposite side on valve block 1 top is provided with check valve 4, and the rear side of valve block 1 is provided with flow regulating valve 3.
This detailed description of the invention mainly designs for manned crane winch, it is on the basis of common winch balance cock, devise especially at the position that balance cock is suitable and can enter the flow regulating valve of drg by hydraulic control oil, conventional balanced valve and flow regulating valve are combined together.
This detailed description of the invention compares common balance cock, adds the specific function of following two aspects:
1., when hydraulic power disappears, utilize the flow regulating valve on this balance cock and the top connection of braking release oil circuit, external hand-hydraulic oil cylinder, according to the method for operation of service instructions, the safety that can realize load accurately declines;
2. the flow regulating valve on balance valve, can block the oil circuit towards drg, can be a kind of effective means that on test winch, brake performance provides.
More than show and describe groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
