Abstract
The utility model relates to a hoist device, in particular to a hydraulic hoisting capacity limiting device of a hoist, which comprises a hoist frame, a lifting chassis, a suspension platform, a sliding touch unit and an alarm. The lifting chassis is provided with the suspension platform; the sliding touch unit and the hoist frame are provided with a sliding contact line which is connected; the sliding contact lines are connected with the alarm; the suspension platform is connected with an oil cylinder arranged on the lifting chassis through a piston rod which is connected with the bottom of the suspension platform; the outer ends of the lifting chassis are respectively an overload signal collector and a sliding touch unit which are electrically connected; and the oil cylinder is connected with the overload signal collector through an oil delivery pipe. The arrangement of the overload signal collector and the alarm can result in the safe and reliable operation of the hoist; the overload alarm and the power breakdown operation can remind the staff that the hoisting overload is dangerous, thereby improving the safety awareness of the staff; and the overload alarm can promptly remind the staff of treating the goods loading condition, thereby improving the work efficiency.
Description
Technical field:
The utility model relates to a kind of gig device, especially a kind of gig fluid pressure type hoisting capacity restraint device.
Background technology:
Existing gig and discharging platform are not installed the hoisting capacity restraint device mostly, cause cargo-carring goods standard to differ, and have a strong impact on the service efficiency and the service life of gig, and be when weight is excessive, dangerous during use.
Summary of the invention:
The technical problems to be solved in the utility model is: provide a kind of when improving service efficiency, ensure gig and discharging platform work safety, improve the gig fluid pressure type hoisting capacity restraint device of staff's awareness of safety simultaneously.
The technical scheme that solves its technical matters employing is: a kind of gig fluid pressure type hoisting capacity restraint device, comprise: lift carriage, the lifting chassis, floating platform, the wiping device, annunciator, it is provided with floating platform described lifting chassis, on described wiping device and the lift carriage trolley sliding block joint is set, this trolley is connected with annunciator, described floating platform is by being connected with the oil cylinder that is provided with on its bottom bonded assembly piston rod and the lifting chassis, outer end, described lifting chassis is equipped with the overload signal picker and the wiping device of electrical connection respectively, is connected by transport pipe between described oil cylinder and the described overload signal picker.
Compared with prior art, the beneficial effects of the utility model are:
Overload signal picker and annunciator by being provided with make gig work safe and reliable; It is dangerous that warning during overload and power operation can be reminded the overload of staff's gig, so staff's awareness of safety is improved; The overload alarm in time reminds the staff to handle the cargo loading situation, has improved work efficiency.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure: lift carriage 1, lifting beam 2, ropes 3, promote cabinet 4, floating platform 5, trolley 6, annunciator 7, power supply 8, relay 9, winch power supply 10, winch 11, wiping device 12, coiled tubing test port one 3, overload signal picker 14, lifting chassis 15, transport pipe 16, oil cylinder 17, piston rod 18.
The specific embodiment:
The utility model is described in further detail below in conjunction with drawings and Examples:
A kind of gig fluid pressure type hoisting capacity restraint device, by lift carriage 1, lifting beam 2, ropes 3, promote cabinet 4, floating platform 5, trolley 6, annunciator 7, power supply 8, relay 9, winch power supply 10, winch 11, wiping device 12, coiled tubing test port one 3, overload signal picker 14, lifting chassis 15, transport pipe 16, oil cylinder 17, piston rod 18, it is provided with floating platform 5 described lifting chassis 15, this floating platform 5 is by being connected with the oil cylinder 17 of setting on its bottom bonded assembly piston rod 18 and the lifting chassis 15,15 outer ends, described lifting chassis are equipped with the overload signal picker 14 and the wiping device 12 of electrical connection respectively, be connected by transport pipe 16 between described oil cylinder 17 and the described overload signal picker 14, on described wiping device 12 and the lift carriage 1 trolley 6 sliding block joints are set, this trolley 6 is connected with annunciator 7.
The utility model principle of work is summarized as follows:
During lade, drive 4 liftings of lifting cabinet by the ropes 3 that is arranged on the lifting beam 2, when carrier is overweight on being positioned at floating platform 5, the gravity of carrier is by oil cylinder 17, piston rod 18 changes into hydraulic coupling, pass to overload signal picker 14 by coiled tubing test port one 3, overload signal picker 14 is triggered during overload, transmit signal by wiping device 12 and trolley 6 and give power supply 8, power supply 8 transmits electric signal and gives the alarm for annunciator 7, transmit electric signal simultaneously and give relay 9, relay 9 gives the winch power supply 10 outages, and winch 11 is not worked.
