Description
Technical field
This utility model belongs to construction machinery equipment technical field, specifically a kind of double safety building hoists.
Background technology
Building hoist is vertical transport personnel and a kind of elevating mechanism of material in construction, is mainly made up of guide rail bracket, cage and actuating device, safety device etc..Quantity according to driver element is different, can be divided into single driving, Dual Drive and three drivings.Wherein single driving elevator drive mechanism is configured with a set of motor reducer, and brake is integrated on motor, and elevator carries out parking brake by this brake.
Single driving elevator only has a set of brake unit, and the reliability of brakes is relatively poor, thus causes the safety of elevator to decline to a great extent.Additionally while be provided with an anti-falling safety device on the cage of elevator, can ensure that in theory when brake system non-functional cage falls, braked by safety, it is ensured that personnel and equipment safety.In actual use, if safety frequent movement, owing to shock of a fall is bigger, in fact it could happen that the situation that in cage, safety gear failure and backgear come off, even there will be the situation of safety self damage and cause safety to lose efficacy, there are major safety risks.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, it is provided that a kind of double safety building hoists, uses double safety design, improves the safety of elevator, eliminate safe hidden trouble.
For realizing above-mentioned technical purpose, the scheme that this utility model provides is: a kind of double safety building hoists, including there is cage, driving plate, braking motor, decelerator, the hoistable platform of trolley frame, trolley frame is connected by sensing bearing pin with cage, plate is driven to be fixed on trolley frame by bolt, braking motor and decelerator are in transmission connection and both of which is installed on driving plate, drive and arrange cage top safety on plate；It is provided with the guard plate being connected with it by bolt in cage, guard plate arranges safety in cage.
The beneficial effects of the utility model are: this pair of safety building hoist modern design, simple in construction, safety is high；In cage, guard plate and safety are identical with Conventional elevator, and cage top drives plate installation dimension to drive plates consistent with conventional two, and trolley frame to drive trolley frame with conventional two consistent, highly versatile, parts making replacing is simply.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the utility model is described in further detail.
The present embodiment provides a kind of double safety building hoist, as depicted in figs. 1 and 2, including there is cage 3, driving plate 5, braking motor 9, decelerator 8, the hoistable platform of trolley frame 1, trolley frame 1 is connected by sensing bearing pin with cage 3, plate 5 is driven to be fixed on trolley frame 1 by bolt, braking motor 9 and decelerator 8 are in transmission connection and both of which is installed on driving plate 5, drive and arrange cage top safety 2 on plate 5；It is provided with the guard plate 7 being connected with it by bolt in cage 3, guard plate 7 arranges safety 4 in cage.
During use, the startup initial value of safety 4 in cage top safety 2 and cage is set to difference.Such as, the initial value that starts arranging cage top safety 2 is failure to actuate more greatly because demarcating speed of action more than the startup initial value of safety 4 in cage, when braking motor 9 brake failure elevator falls, the leading action of safety 4 in cage, cage top safety 2；After in cage, safety 4 causes brake fade because of reasons such as parts damages, safety 2 action of cage top, ensure that elevator runs safety by double safeties.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model principle; can also make some improvement or deformation, these improve or deformation also should be regarded as protection domain of the present utility model.
