Abstract
The utility model relates to a safety hook of a lift. The safety hook of the lift comprises a hook body, the hook body is wholly cast into a piece-type structure, and connecting holes and reinforcing ribs are arranged on the surface of the hook body. The safety hook of the lift has the advantages that the hook body of the safety hook of the lift is cast into the piece-type structure (similar to a plate-shaped structure), contacting area of the hook body with stand columns/transmission beams of a cage is increased, intensity is reinforced, and the safety hook of the lift is safe and reliable. The reinforcing ribs are arranged on the surface of the outer side of the hook body, so that whole intensity is further enhanced. Bosses are arranged at both ends of the connecting holes so that a thickened part is formed and connection is stable and reliable by bolts. The hook body is arranged on the stand columns/the transmission beams of the cage by mounting bolts so as to prevent the cage/a transmission mechanism from being isolated from a guide rail rack in case of damage of a trolley or other emergency conditions.
Description
Technical field
The utility model relates to elevator technology field, especially safety hook for elevator.
Background technology
China Patent No. CN201020696214.4 discloses a kind of safety hook for elevator on August 24th, 2011, comprise coupler body, rivet and bolt, the rivet lower end is connected with the coupler body top, and the rivet upper end is fixed on the major trough steel of elevator craning cage or bogie, and is bolted.Owing to being provided with rivet and bolt, the rivet lower end is connected with the coupler body top, the rivet upper end is fixed on the major trough steel of elevator craning cage or bogie, and when installing and using, fix with bolt again, therefore when disassembling bolts, hook with safety tong still hangs on the installation site of major trough steel by rivet, the phenomenon of neglected loading when effectively having avoided installing.But because the cross section of coupler body becomes cylindrical structural, the area of contact of itself and major trough steel is little, and it is unreliable to connect, and haves much room for improvement.
The utility model content
The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, and provides a kind of simple and reasonable for structure, has increased area of contact and has strengthened intensity, and is more safe and reliable, and easy for installation, attractive and durable safety hook for elevator.
The purpose of this utility model is achieved in that
Safety hook for elevator comprises coupler body, it is characterized in that, described coupler body inblock cast becomes slice structure, and the surface is provided with connecting bore and strengthens gusset.
The purpose of this utility model can also adopt following technical measures to solve:
As a kind of scheme more specifically, described reinforcement gusset is provided with three, and the uniform outer surface that is arranged on coupler body.
The connecting bore two ends of described coupler body are provided with boss.
The beneficial effects of the utility model are as follows:
(1) coupler body of this kind of safety hook for elevator is cast as slice structure (being similar to platy structure), has increased with cage column/transmission contact of beams area and strengthens intensity, and is more safe and reliable;
(2) the coupler body outer surface is provided with the reinforcement gusset, has further strengthened whole intensity;
(3) the connecting bore two ends are provided with boss, thereby form the position of a thickening, bolt are connected more firm, reliable;
(4) with hold-down bolt coupler body is installed on cage column/transmission beam cage/transmission device getaway frame in the time of can preventing that roller from damaging or under other emergency case.
Description of drawings
Fig. 1 is the utility model one embodiment mounting structure schematic diagram.
Fig. 2 is the plan structure schematic diagram that coupler body is connected with cage column/transmission beam.
Fig. 3 is the hook body structure schematic diagram.
Fig. 4 is the left TV structure schematic diagram of Fig. 3.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figures 1 to 4, this safety hook for elevator comprises coupler body 2, and described coupler body 2 inblock casts become slice structure, and the surface is provided with connecting bore 23 and brace panel 21.
Described brace panel 21 is provided with three, and the uniform outer surface that is arranged on coupler body 2.
Connecting bore 23 two ends of described coupler body 2 are provided with boss 22.
Described coupler body 2 is installed on cage column/transmission beam 1 by bolt 3, and bolt 3 passes connecting bore 23 coupler body 2 and cage column/transmission beam 1 are linked into an integrated entity, cage/transmission device getaway frame when preventing that roller from damaging or under other emergency case.
