Abstract
The utility model discloses a bidirectional safety catching hook which comprises a hook handle and a bidirectional hook body connected to the lower end of the hook handle. By the aid of the bidirectional safety catching hook, serious personal casualty accidents caused by breakage of traction steel wire ropes during personnel transport by wide-angle elevated cable cars can be effectively prevented, potential safety risks are eradicated, and the requirement on safety production can be met.
Description
Technical field
The utility model relates to a kind of bidirectional safe arresting hook.
Background technology
The colliery overhead manned equipment mainly is made up of actuating device, rope supporting device, aircraft, roundabout wheel device, tightening device and electrical controller etc.The overhead manned equipment principle of work is: the annular wire rope that it is good to peg graft in two ends is installed on actuating device and the return sheave, and the centre is fixed with holder rope sheave, press rope wheel etc., and carries out tensioning by counterweighted take-up.Electrical motor by actuating device during overhead manned equipment work drives the reductor rotation through coupler; Reductor drives the drive wheel rotation, makes the steel rope that is wrapped between drive wheel and the return sheave do electrodeless circular flow, or operation up and down reciprocatingly; Earlier chair lift is connected with rope clamping device; Again rope clamping device is locked on the steel rope of operation,, thereby realizes conveying personnel's purpose along with the steel rope upstream or downstream.Wide-angle is built on stilts takes advantage of people's cable car in transporting personnel's process, during the traction steel wire fracture of rope, may cause great human casualty accident.
The utility model content
The purpose of the utility model provides the bidirectional safe arresting hook that a kind of mine wide-angle takes advantage of people's cable car rope broken protector to use; Prevent to take advantage of people's cable car traction steel wire fracture of rope in transporting personnel's process to cause great human casualty accident because of wide-angle is built on stilts; Eliminate safe hidden trouble, satisfy the needs of safety in production.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of bidirectional safe arresting hook comprises the neck of hook and has the coupler body of two-way suspension hook with neck of hook lower end bonded assembly.
The said neck of hook is made up of linkage section that has connecting bore and bending segment, and said linkage section and bending segment vertically part are angle a, and angle a is 10 °～20 °; Said coupler body is by forming with the vertical part bonded assembly of bending segment bar portion and bar subordinate end curved suspension hook that is circular arc on both sides.
When the utility model uses; Catch hook to bidirectional safe and be fixed on each coventional type belleville spring formula fixed rope clip binding bolt, making it becomes with this rope clamping device, makes bidirectional safe catch hook and arrest the horizontal title of slideway and keeps certain safety distance; When fracture takes place in haulage cable; The steel rope of drive wheel both sides respectively under the effect of steel rope, chair lift, personnel's gravity etc., the down landing of chair lift and passenger, final two-way arresting hook will be fallen and arrest in the slideway; And catch on and arrest stull, guaranteed the safety of personnel and equipment.Through actual pull test, pulling force is 24.6KN when making it that deformation take place, and can satisfy user demand fully.

Fig. 3 is the utility model running condition figure.
The specific embodiment
Like Fig. 1, shown in Figure 2, a kind of bidirectional safe arresting hook comprises the neck of hook and has the coupler body of two-way suspension hook with neck of hook lower end bonded assembly.The neck of hook is made up of linkage section that has connecting bore 73 71 and bending segment 74, and said linkage section 71 is angle a with the vertical part 75 of bending segment, and angle a is 10 °～20 °; Coupler body is by forming with bending segment vertical part 75 bonded assembly bar portions 72 and bar subordinate end curved suspension hook 76 that is circular arc on both sides.
As shown in Figure 3, the mine wide-angle is taken advantage of people's cable car rope broken protector, comprise be arranged at the both sides, tunnel arrest slideway 11 (it selects steel pipe for use), arrest to be provided with laterally on the slideway 11 and arrest stull 10, arrest stull 10 and whenever be provided with one at a distance from 0.5 meter; Bidirectional safe arresting hook 7 in the utility model is fixedly connected on the rope clamping device of captiveing joint with steel rope 5; Bidirectional safe arresting hook 7 is positioned at the top of arresting stull 10, when wire cable rupture (as shown in Figure 3), and steel rope 5 landing from the support roller 8; Bidirectional safe arresting hook 7 falls to arrests slideway 11 and catches on and arrest stull 10; Prevent that suspension rod 12 and chair lift 13 from continuing to fall, guarantee the safety of personnel and equipment, prevent to take advantage of people's cable car traction steel wire fracture of rope in transporting personnel's process to cause great human casualty accident because of wide-angle is built on stilts; Eliminate safe hidden trouble, satisfy the needs of safety in production.
Claims (2)
1. a bidirectional safe arresting hook is characterized in that, comprises the neck of hook and has the coupler body of two-way suspension hook with neck of hook lower end bonded assembly.
2. bidirectional safe arresting hook as claimed in claim 1 is characterized in that the said neck of hook is made up of linkage section that has connecting bore and bending segment, and said linkage section and bending segment vertically part are angle a, and angle a is 10 °～20 °; Said coupler body is by forming with the vertical part bonded assembly of bending segment bar portion and bar subordinate end curved suspension hook that is circular arc on both sides.
