Description
one, technical field
The utility model relates to the Performance Detection technology of tower crane, particularly for the static brake moment data test device of the luffing of tower crane or the second brake protection device normally closed type power hydraulic pressure spot-type disc brake of hoisting gear.
two, background technology
According to specifying in GB/T5031-2008 " tower crane " standard 5.4.1.4.3 mobile arm amplitude mechanism clause: " for preventing that foundation brakes or driving mechanism lost efficacy; and provide braking when possibly motor and foundation brakes being changed or keeped in repair, should be provided with can by operate all with overspeed protection switch control, directly act on the additional brake on reel edge." and normally closed type power hydraulic pressure spot-type disc brake is widely used in the luffing of tower crane or the second brake protection device of hoisting gear, because tower machine belongs to special equipment, so the requirement of the safe reliability of the detent that it is used is high.When general motor has driving force, detent in open mode without any braking maneuver, once the first brake fade, electric-control system can trigger hydraulic caliper-disc brake (being second brake) action immediately, clamp system reel edge, make mechanism reach emergency braking condition by detent static brake frictional resistance, avoid the generation of security incident.Therefore, the safe handling to tower crane whether up to standard of the static brake moment of hydraulic caliper-disc brake is vital.
three, summary of the invention
The purpose of this utility model is to provide a kind of normally closed type power hydraulic pressure spot-type disc brake testing table, by simulation hydraulic caliper-disc brake static brake operating mode, surveys and judges whether hydraulic caliper-disc brake static brake meets designing requirement.
The technical solution adopted in the utility model is: normally closed type power hydraulic pressure spot-type disc brake testing table has a workbench, is equipped with power supply box and hydraulic power unit on workbench, and power supply box connects display and hydraulic power unit by cable; On workbench, be provided with static pressure measurement dish, the hydraulic clamp of normally closed type power hydraulic pressure spot-type disc brake is clipped on the side of static pressure measurement dish, the hydraulic tube of hydraulic power unit connects hydraulic clamp, at a connecting-rods with constant lengh of static pressure measurement dish opposite side welding, and a hydraulic jack is installed below the outer end of connecting-rods with constant lengh, on hydraulic jack, with connecting-rods with constant lengh joint setting pressure sensor, the electric signal of pressure transducer is accessed to display.
This device is according to lever principle, utilizes disk simulation mechanism reel listrium, makes the static brake operating mode of hydraulic caliper-disc brake in disk is clamped.And then imposed load on the connecting-rods with constant lengh welding to the disk other end, working pressure sensor and display read the load that disk connecting-rods with constant lengh bears, in the time that imposed load reaches the rated load of hydraulic caliper-disc brake brake stator, disk should keep not rotating under hydraulic caliper-disc brake effect, and hydraulic caliper-disc brake static brake meets designing requirement.Thereby ensure the safe reliability of hydraulic caliper-disc brake static brake, and in design, take into full account convenience and the test accuracy of operation to there is the features such as principle is simple to operation.
