Abstract
The utility model discloses a kind of hydraulic push rod type break, form primarily of brake shoe, brake arm, brace, main spring, set square triangle lever, push rod and hydraulic driver, two described brake arms are respectively equipped with brake shoe, between two brake arms, upside is provided with main spring, set square triangle lever is provided with above the brake arm of right side, pass on left brace with set square triangle lever above left hand brake arm to be connected, set square triangle lever lower right-hand side is provided with push rod, connects hydraulic driver below push rod.The utility model, in order to overcome the large shortcoming of electromagnetic blocked brake impact force, have employed hydraulic push rod block brake.Their difference is that its power that declutches relies on moving up and down of the push rod in hydraulic driver, then affects brace to complete braking by triangle lever, stable working, noiseless; Allow per hourly to connect electric number of times and can reach 720 times, long service life.
Description
Technical field
The utility model belongs to break technical field, is specifically related to a kind of hydraulic push rod type break.
Background technique
Break is the vitals ensureing crane safety, normal work.Conventional block brake on travelling crane, it is a kind of simple, reliable break.Block brake can be divided into again short stroke, Long travel and hydraulic push rod block brake.Short stroke and Long travel break, its basic structure and working principle can consult relevant books.Break many uses single phase poaer supply of short stroke, break many uses three phase mains of Long travel.Long travel break has the longer arm of force due to its lever, therefore have larger braking moment, and the braking force of short stroke break is relatively little.The shortcoming that when they have an action, impact force is large, needs often to safeguard and maintenance.
Model utility content
The purpose of this utility model is to provide a kind of hydraulic push rod type break, to solve the deficiency existed in such scheme.
In order to achieve the above object, the technological scheme that the utility model adopts is:
A kind of hydraulic push rod type break, form primarily of brake shoe, brake arm, brace, main spring, set square triangle lever, push rod and hydraulic driver, two described brake arms are respectively equipped with brake shoe, between two brake arms, upside is provided with main spring, set square triangle lever is provided with above the brake arm of right side, pass on left brace with set square triangle lever above left hand brake arm to be connected, set square triangle lever lower right-hand side is provided with push rod, connects hydraulic driver below push rod.
Described main spring is provided with spring buffer.
All fixed element is provided with below described brake arm He below hydraulic driver.
The utility model, in order to overcome the large shortcoming of electromagnetic blocked brake impact force, have employed hydraulic push rod block brake.Their difference is that its power that declutches relies on moving up and down of the push rod in hydraulic driver, then affects brace to complete braking by triangle lever, stable working, noiseless; Allow per hourly to connect electric number of times and can reach 720 times, long service life.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
1-brake shoe; 2-brake arm; 3-brace; 4-main spring; 5-set square triangle lever; 6-push rod; 7-hydraulic driver.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As shown in Figure 1, a kind of hydraulic push rod type break, form primarily of brake shoe 1, brake arm 2, brace 3, main spring 4, set square triangle lever 5, push rod 6 and hydraulic driver 7, it is characterized in that: two described brake arms 2 are respectively equipped with brake shoe 1, between two brake arms 2, upside is provided with main spring 4, set square triangle lever 5 is provided with above the brake arm 2 of right side, pass on left brace 3 with set square triangle lever 5 above left hand brake arm 2 to be connected, set square triangle lever 5 lower right-hand side is provided with push rod 6, connects hydraulic driver 7 below push rod 6; Described main spring 4 is provided with spring buffer; All fixed element is provided with below described brake arm 2 He below hydraulic driver 7.
