Abstract
The utility model relates to a protection device for preventing a shaped steel derrick hanging basket from dropping off. The utility model is composed of two symmetrical eccentric wheel rail clamping devices, wherein each eccentric wheel rail clamping device comprises a draw rod (1) which is fixedly connected with a swing rod of a hanging basket, a crank arm (7) which is fixedly connected with the draw rod (1) and is provided with a drive rod (3), wherein the drive rod (3) is connected with a link mechanism (4). One end of the link mechanism (4) is provided with a tension spring (5), and the other end is provided with a pair of gears (6). An eccentric wheel pair (7) is installed on a gear shaft of the gears (6). The utility model has the characteristics of simpler structure, simple manufacture, convenient installation, low cost, flexible action and strong reliability. The utility model can be used on shaped steel derrick lifters, and can be used as a safety device for preventing a hanging basket from dropping off.
Description
The utility model relates to the safety guard of lifting machinery, the safety guard that particularly a kind of hanging basket that prevents shaped steel derrick elevator falls.
The lifting transportation device of building unit regulation use at present is a shaped steel derrick elevator, because the steel rope of elevator can wear and tear in long-term use, as fail in time to change, the time have the phenomenon of wire cable rupture to take place, steel rope is once the hanging basket falling accident will take place in fracture, and the personnel that cause injure or material damage, for construction safety, supervisory management zone all requires unit in charge of construction to install the safety device that prevents that hanging basket from falling additional usually.Because what generally used in the past is the tubular derrick elevator, the shaped steel derrick elevator that is not suitable for that its anti-fall device has uses, have then structurally too complexity make cost of manufacture higher.The lifting transportation device of construction unit is a kind of easy mechanical equipment, and its self-value is lower, needs the installation of often changing places again, therefore, have only and protect reliably, be easy to install, and the not high anti-fall device of price just may be accepted extensively by unit in charge of construction.
The purpose of this utility model is: provide that a kind of structure is simple, reliable in action, be easy to the shaped steel derrick hanging basket anti-fall device that price is lower is installed.
Formation of the present utility model: it is made of the eccentric wheel rail clamping device of two cover symmetries.The formation of eccentric wheel rail clamping device comprises, the pull bar (1) of captiveing joint with the hanging basket fork, captive joint the connecting lever (2) that has drive link (3) with pull bar (1), drive link (3) is connected to connecting rod mechanism (4), one end of connecting rod mechanism (4) has extension spring (5), the other end has a gear mesh (6), eccentric wheel is housed to (7) on the gear wheel shaft of gear mesh (6).
Compared with the prior art, the utility model has been simplified the structure of hanging basket anti-fall device, and it is simpler to make that whole anti-fall device has structure, is easy to make, is convenient to install, cost is low, be active in one's movements, the characteristics of good reliability.Can be widely used on the shaped steel derrick elevator, as preventing that the safety device that hanging basket falls from using.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Accompanying drawing 1 is an organigram of the present utility model;
Accompanying drawing 2 is running condition scheme drawings of the present utility model.
Embodiment: the utility model is made of the eccentric wheel rail clamping device of two cover symmetries, and what provide in the accompanying drawing 1 is the structure of a cover eccentric wheel rail clamping device.The formation of eccentric wheel rail clamping device comprises, the pull bar (1) of captiveing joint with the hanging basket fork, captive joint the connecting lever (2) that has drive link (3) with pull bar (1), drive link (3) is connected to a connecting rod mechanism (4), one end of connecting rod mechanism (4) has extension spring (5), the other end has a gear mesh (6), eccentric wheel is housed to (7) on the gear wheel shaft of gear mesh (6).
During use, one cover eccentric wheel rail clamping device is installed respectively symmetrically in the left and right sides at hanging basket top, wherein drive link (3) is fixed on and is contained on the carriage that hangs blue top, extension spring (5) is fixed on hangs on the blue sidewall, and eccentric wheel is clamped in as the derrick column (7) holds concurrently on the angle steel of elevator guide rails.Fork on the steel rope is because of being the upright position under dead weight of basket and the action of gravity at ordinary times, by pull bar (1), connecting lever (2), drive link (3) extension spring (5) is elongated simultaneously and produced the preparation pulling force, this moment, eccentric wheel was to there being bigger space between (7), made the hanging basket can free up-and-down movement.Once wire cable rupture, pull bar (1), connecting lever (2) lose the constraint of fork can reverse an angle, add that extension spring (5) desire restores to the original state, drivening rod mechanism (4) action, connecting rod mechanism (4) makes gear mesh (6) action, gear mesh (6) drive eccentric wheel again and (7) are done corresponding rotation and presss from both sides extremely on angle steel.
Claims (1)
1, shaped steel rises the anti-fall protection device of frame hanging basket, it is characterized in that: its formation comprises the eccentric wheel rail clamping device of two cover symmetries, the formation of eccentric wheel rail clamping device comprises, the pull bar (1) of captiveing joint with the hanging basket fork, captive joint the connecting lever (2) that has drive link (3) with pull bar (1), drive link (3) is connected to a connecting rod mechanism (4), and an end of connecting rod mechanism (4) has extension spring (5), the other end has a gear mesh (6), eccentric wheel is housed to (7) on the gear wheel shaft of gear mesh (6).
