Description

A kind of suspension hook

Technical field

The utility model relates to the suspender of elevator machinery, specifically is a kind of suspension hook.

Background technology

Suspension hook is the common suspender of elevator machinery, and suspension hook is suspended on the steel rope of lifting mechanism by means of parts such as assembly pulleys usually, when weight is lifted by crane, through the steel rope that is suspended on the suspension hook weight is bundled, lifts by crane.Yet; Because the suspension hook handle of suspension hook and the space between the bill are what open wide; In the process of hoisting heavy, in case steel rope loses suddenly to lower pulling force, steel rope can rebound out in moment, and (steel rope all is to adopt stranded the forming of high-quality spring wire to suspension hook; It has good tension intensity and elasticity), thus the safe in utilization and operating personnel's of elevator machinery personal safety is formed significant threat.

In order to eliminate above-mentioned potential safety hazard, the most existing suspension hook all is provided with anticreep rope mechanism, and this suspension hook with anticreep rope mechanism is of common occurrence on public publication.Wherein, Modal suspension hook with anticreep rope mechanism is referring to Fig. 1: on the suspension hook handle 01 of suspension hook, be provided with permanent seat 02; The inner of anti-flake 07 is connected on the permanent seat 02 through screw rod 03 hinge, on screw rod 03, is with torque spring 04, and the outer end of anti-flake 07 contacts with the bill 05 of suspension hook; Thereby make the suspension hook handle 01 and the sealing of the space between the bill 05 of suspension hook, the steel rope 06 that prevents to be suspended on the suspension hook comes off.Though this suspension hook can prevent steel rope 06 and come off, and in the use of reality, has defectives such as troublesome poeration, fastness difference; This be because: when suspension hook takes off steel rope 06, need to prevent that flake 07 presses, this is for the less steel rope of specification; There are not much problems, but for the bigger steel rope of specification, very trouble; Require a people to push down anti-flake 07, another people takes off steel rope 06 from suspension hook, depends the operation that a people is difficult to accomplish the anti-flake 07 of the pressure that links up, gets steel rope 06 alone; Labour intensity is very big, wastes time and energy; In addition, anti-flake 07 is connected on the permanent seat 02 of suspension hook handle 01 through screw rod 03 hinge, and its Joint strenght is very low, and fastness is poor, and anti-flake 07 is easy to bumped by steel rope 06 askew, and reliability is low.These defectives make above-mentioned suspension hook can't fundamentally solve potential safety hazard.

Summary of the invention

The purpose of the utility model is: to the deficiency of above-mentioned prior art, a kind of easy to operate, fastness good, reliability is high, practical suspension hook is provided.

The technical scheme that the utility model adopts is, a kind of suspension hook comprises the suspension hook handle, and said suspension hook handle is provided with anticreep rope mechanism, and said anticreep rope mechanism mainly is made up of anchor ear, handle, pipe link, stop block, spring and anti-drop rod; Wherein, said anchor ear is fixed on the suspension hook handle, and the top of anchor ear outside wall surface is provided with locating button, has the location square hole on the locating button, and the bottom of anchor ear outside wall surface is provided with and the corresponding clip of locating button; Said pipe link passes locating button and clip, and the upper end of pipe link is connected with handle, and the lower end of pipe link is connected with anti-drop rod; Said spring housing is on the pipe link between locating button and the clip, and the bottom of spring is against on the clip; Said stop block is fastened on the pipe link on spring top, and the top of stop block is a step surface, and the location square hole on this step surface and the locating button is complementary; The outer end of said anti-drop rod contacts with the bill of suspension hook.

Said pipe link passes from the location square hole of locating button.

Said anchor ear passes through bolted on the suspension hook handle.

The beneficial effect of the utility model is: the suspension hook of said structure has been set up anticreep rope mechanism on suspension hook under the prerequisite that does not influence hoisting function, no matter be to get from suspension hook to take off steel rope or hang up steel rope; Can easily accomplish per capita for one, easy to operate, and also bulk strength is high; Fastness is good; Can stop effectively that in actual application the steel rope bounce-back comes off, eliminate the significant threat to operating personnel's personal safety and elevator machinery formation safe in utilization, reliability is high; Practical, durable in use.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a kind of structural representation of existing suspension hook.

Fig. 2 is a kind of structural representation of the utility model.

The specific embodiment

Referring to Fig. 2: the utility model comprises suspension hook handle 1, and parts such as the upper end of suspension hook handle 1 and assembly pulley are connected, and on suspension hook handle 1, are provided with anticreep rope mechanism.Anticreep rope mechanism mainly is made up of anchor ear 3, handle 4, pipe link 5, stop block 7, spring 8 and anti-drop rod 9.Wherein, Anchor ear 3 is fastened on the suspension hook handle 1 through bolt 2, and the top of anchor ear 3 outside wall surface is provided with locating button 6, has the location square hole on the locating button 6; The bottom of anchor ear 3 outside wall surface is provided with and locating button 6 corresponding clips 12; The perforation that has pipe link 5 on the clip 12, the diameter of location square hole is greater than the diameter of pipe link 5, also greater than the penetration hole diameter on the clip 12; Pipe link 5 passes the perforation of the location square hole and the clip 12 of locating button 6, captives joint with handle 4 in the upper end of pipe link 5, and the lower end of pipe link 5 is connected with anti-drop rod 9 through jam nut; Spring 8 is sleeved on the pipe link 5 between locating button 6 and the clip 12, and the bottom of spring 8 is against on the clip 12; Stop block 7 is fastened on the pipe link 5 on spring 9 tops, and the top of stop block 7 is a step surface, and the location square hole on this step surface and the locating button 6 is complementary, and the location square hole is also taken into account the screens of stop block 7 when serving as pipe link 5 perforation; The outer end of anti-drop rod 9 contacts with the bill of suspension hook 10, thereby makes the suspension hook handle 1 of suspension hook and the space between the bill 10 form sealing, and the steel rope 11 that prevents to be suspended on the suspension hook comes off.

The working process of the utility model is: when steel rope 11 need be hanging on the suspension hook, pinch handle 4, and pushing downwards, stop block 7 withdraws from the location square hole on the locating button 6; Spring 8 is compressed, and with handle 4 half-twists, anti-drop rod 9 is along with half-twist; Make the space open between suspension hook handle 1 and the bill 10, release handle 4 is under the effect of spring 8; Stop block 7 automatic screens are in the square hole of the location of locating button 6, and anti-drop rod 9 keeps, and steel rope 11 is hung suspension hook; Through operations such as pushing, rotary handles 4, make the space sealing between suspension hook handle 1 and the bill 10, prevent that steel rope 11 comes off in the use; When steel rope 11 need be got when taking off from suspension hook; Through operations such as pushing, rotary handles 4, make the space open between suspension hook handle 1 and the bill 10, take off steel rope 11 from suspension hook to get final product; Very convenient, the sequence that the people can easily accomplish lanyard or get rope fully.
