Abstract
A novel anti-falling device is mainly composed of an adjusting screw, a spring, a fastening nut, a dovetail groove support, a supporting shaft, guiding wheels, a supporting plate, a rack, a dust shield, a small gear and an eccentric clamping wheel. The novel anti-falling device is characterized in that the adjusting screw is used for adjusting the spring, the fastening nut and the dovetail groove support are used for fixing the supporting shaft, the supporting plate supports the guiding wheels, the supporting plate is covered with the dust shield, and the spring drives the rack to move so as to drive the small gear and the eccentric clamping wheel. The novel anti-falling device has the advantages that the novel anti-falling device is installed on the top of a lifting cage and moves up and down along a guiding tube of a lifter frame body through the guiding wheels, when working normally, the novel anti-falling device moves up and down along with the lifting cage, and when a rope is loosened or broken, the lifting cage descends rapidly, the novel anti-falling device can lift the whole lifting cage and prevent the lifting cage from falling; the novel anti-falling device is safe, reliable and rapid and convenient to install.
Description
Technical field
The utility model relates to building hoist field, and what be specifically related to is a kind of novel falling proof device.
Background technology
Building hoist is a kind of machinery by cage vertical transport people, thing, at goods with on building hoist, the general steel rope that adopts draws cage, if meet steel rope abrasion or rupture suddenly because external force causes cage operational process steel rope, to cause cage falling accident, in view of the difficult foresight of this type of accident and the massive losses causing thus, imagination provides a kind of novel falling proof device to solve this difficult problem.
Utility model content
The purpose of this utility model is just to provide a kind of novel falling proof device.
The technical solution adopted in the utility model is: a kind of novel falling proof device, mainly by governing screw, spring, clamp nut, dovetail furrow bearing, pivot shaft, track adjusting wheel, stay bearing plate, tooth bar, dust boot, miniature gears and eccentric clamping wheel, formed, governing screw fixing spring, clamp nut and dovetail furrow bearing fixed pedestal axle, stay bearing plate supporting guide wheel, dust boot covers on stay bearing plate, thereby the action of spring band carry-over bar drives miniature gears, cam lock bearing up pulley.
Described Novel anti-falling dropping control device is arranged on the crossbeam of both sides, cage top by dovetail furrow bearing.
On described cam lock bearing up pulley, be provided with master scale line.
Described track adjusting wheel folder leans against on the guide pipe of Frame of elevator installation.
This falling proof device is arranged on the crossbeam of both sides, cage top by dovetail furrow bearing, track adjusting wheel folder leans against on the guide pipe of Frame of elevator installation, during normal operation, this falling proof device is along guide pipe up-and-down movement, when pine, disconnected rope, cage declines rapidly, thereby tooth bar action drives miniature gears, cam lock bearing up pulley, and cam lock bearing up pulley is clamped on guide pipe, and whole cage is sling and do not made it fall, thereby reach the object of safety, when steel rope reparation; When cage rises again, thereby the action of spring band carry-over bar drives miniature gears, cam lock bearing up pulley, cam lock bearing up pulley is reversed and reset, and automatically terminates locking state, and elevator recovers normal operation, is provided with master scale line on cam lock bearing up pulley.
The beneficial effects of the utility model: be arranged on cage top, guide pipe up-and-down movement by leading sheave along Frame of elevator, during normal operation, this falling proof device is with cage up-and-down movement, when pine, disconnected rope, cage declines rapidly, and whole cage is sling and do not made it fall, safe and reliable, quick and easy for installation.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
