Background technology
The assembly pulley of crane in bridge type is usually by compositions such as movable pulley, fixed pulley (if fixed pulley plays equilibrium activity, claiming equalizer pulley again) and steel ropes.In the practical operation of crane in bridge type; because influences such as human element, site condition; tilt to hang thing and be difficult to avoid; often cause steel rope " side races " to occur at the fixed pulley place, thereby make steel rope and pulley lateral margin, anticreep frid etc. push, wear and tear, and fixed pulley is installed on the reel downside usually; be in the high-altitude; be difficult for to check, handle, the time regular meeting wire cable rupture accident takes place because of excessive wear, threaten production safety.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of steel rope fender guard that is used for crane in bridge type fixed pulley place, makes the practical life of steel rope obtain prolonging.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of steel rope fender guard that is used for crane in bridge type fixed pulley place is provided, comprise support frame, two vertical bearing pins, two horizontal bearing pins, vertical sleeve and transverse sleeves, described support frame is made up of two longitudinal vertical plates, two transverse vertical plates and two gussets; Be welded with described two longitudinal vertical plates between described two transverse vertical plates, and constitute box type construction; The outside of described two transverse vertical plates is welded with a gusset respectively; All have two holes on described every transverse vertical plate and the longitudinal vertical plate; Two holes that described two vertical bearing pins pass respectively on the described transverse vertical plate are fixed between two transverse vertical plates; Two holes that described two horizontal bearing pins pass respectively on the described longitudinal vertical plate are fixed between two longitudinal vertical plates; On the described every horizontal bearing pin transverse sleeves is installed; On described every vertical bearing pin two vertical sleeves are installed.
Described vertical bearing pin carries out axial location by pad and spring cotter on transverse vertical plate; Described horizontal bearing pin carries out axial location by pad and spring cotter on longitudinal vertical plate.
Described transverse vertical plate, longitudinal vertical plate and gusset all adopt the Q235 steel plate.
Described horizontal bearing pin and vertical bearing pin all adopt the Q235 round steel.
Described transverse sleeves and vertical sleeve are steel pipe or copper pipe.
Beneficial effect
Owing to adopted above-mentioned technical scheme, the utility model compared with prior art, have following advantage and good effect: (1) can solve the wear and rupture problem that produces when the crane in bridge type steel rope " side race " phenomenon occurs at the fixed pulley place, abatement apparatus hidden danger, the safe operation of support equipment; (2) adopt rolling friction, replace sliding friction, can reduce the wearing and tearing of steel rope, improve the practical life of steel rope; (3) make simply, with low cost, be easy to realize.
Description of drawings
Fig. 1 is an assembling scheme drawing of the present utility model;
Fig. 2 is the birds-eye view after Fig. 1 dextrorotation turn 90 degrees;
Fig. 3 is a design sketch of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
The utility model relates to a kind of steel rope fender guard that is used for crane in bridge type fixed pulley place, as depicted in figs. 1 and 2, comprises the vertical bearing pin of support frame, two 2, two horizontal bearing pins 4, vertically sleeve 9 and transverse sleeves 8.
Described support frame is made up of two longitudinal vertical plates 1, two transverse vertical plates 3 and two gussets 6.Be welded with two longitudinal vertical plates 1 between two transverse vertical plates 3, and constitute box type construction.The outside of two transverse vertical plates 3 is welded with a gusset 6 respectively.Support frame and dolly base plate weld together by longitudinal vertical plate 1, transverse vertical plate 3 and gusset 6 constitute need be trapped among steel rope the box type construction the inside if steel rope has been put on when welding.The material of longitudinal vertical plate 1, transverse vertical plate 3 and gusset 6 and specification can be selected according to the load size of fixed pulley size and the locus that should locate and steel rope, require steel plate that good welding performance is arranged, and generally can select the Q235 steel plate.
All have two on every transverse vertical plate 3 and the longitudinal vertical plate 1 and be used for the mount pin axis hole.Two holes that two vertical bearing pins 2 pass respectively on the transverse vertical plate 3 are fixed between two transverse vertical plates 3, and two holes that two horizontal bearing pins 4 pass respectively on the longitudinal vertical plate 1 are fixed between two longitudinal vertical plates 1.Laterally the material of bearing pin 4 and vertical bearing pin 2 and size can be selected according to actual loading and space condition, generally can select the Q235 round steel.
Vertically bearing pin 2 and horizontal bearing pin 4 are load parts that vertical sleeve 9 and transverse sleeves 8 are installed.Transverse sleeves 8 is installed on the horizontal bearing pin 4, on the every horizontal bearing pin 4 transverse sleeves 8 is installed.Vertically sleeve 9 is installed on vertical bearing pin 4, and two vertical sleeves 9 are installed on every vertical bearing pin 4.At the synchronization of device real-world operation, every sleeve contacts with 1 steel rope at most.The material of bush material can adopt common steel tube according to field condition, also available copper pipe, and the relative attriting performance of copper pipe is quite a lot of, but the wearing and tearing of itself relatively can be big.The internal diameter of sleeve should be more bigger than the external diameter of bearing pin, so that it rotates on bearing pin flexibly.In addition, installing and will be between sleeve and bearing pin during maintenance, and grease-added in appearance, to reduce friction.
Pad 5, spring cotter 7 are vertical bearing pin 2 and the horizontal axial location part of bearing pin 4 on support frame.The axial play momentum that pad 5 and spring cotter 7 are installed rear pin shaft should be controlled at the thickness (as far as possible littler) of a pad, otherwise can adjust by the method for shimming.
As shown in Figure 3, the method that the utility model is arranged the rolling sleeve around adopting, hunting range when both the side race appears in may command steel rope 10 at fixed pulley 11 places, prevent that itself and fixed pulley 11,12 of anticreep frids from producing extruding, wearing and tearing, can reduce the friction between steel rope 10 and protective device again, thereby guarantee the safety of crane in bridge type operation, and improve the practical life of steel rope 10.
