Abstract
The utility model relates to the disassembly of hinge pins of large structural members, particularly relates to a spiral pin remover for performing hinge pin disassembly, which solves the problems that disassembly of the hinge pins of the conventional structural member is time-saving, labor-saving and difficult. The spiral pin remover comprises a screw rod with one end capable of directly or indirectly being fixed with a bolt hole on a hinge pin to be disassembled, and a support frame which is used for supporting the screw rod to ensure that the screw rod is perpendicular to the end surface of the hinge pin to be disassembled and can move along the direction perpendicular to the end surface of the hinge pin to be disassembled, wherein a nut which can be propped against the support frame is arranged at the other end of the screw rod; and the position where the support frame is matched with the screw rod is positioned between the end part where the screw rod is fixed on the hinge pin to be disassembled and the nut. The spiral pin remover has a simple and reasonable structure and good use effect, is time-saving and labor-saving, and is applicable to the hinge pin assembly when a hydraulic support used for a long time underground is repaired.
Description
Technical field
The utility model relates to the bearing pin dismounting of large-sized structural parts, specifically is a kind of spiral pin removal of implementing the bearing pin dismounting.
Background technology
Mine hydraulic bracket is when carrying out repair demolition, because the big bearing pin of band screw is after using a period of time through the down-hole on the support, the axis hole mating surface can deform because of reasons such as wearing and tearing, corrosion, so very difficult during the bearing pin dismounting.
And general way all is to implement dismounting by servicing unit, for example: be fixed with the rod member that impact block and end can be threaded with the screw on the pin roll end face-be the impacting type pin removal on it, during use, be threaded fixing with screw on the pin roll end face Rod end, outwards knock impact block, utilize the outside impact of impact block that bearing pin is extracted.The required impact of this dismounting mode is bigger, exert oneself is directly given power into people worker, need multiple impact, bearing pin could be extracted, very waste time and energy, and for the used hydraulic support in the down-hole for a long time, implement and be still the comparison difficulty: because the type body of hydraulic support is all bigger now, pin diameter all exists
More than, weight is generally all about 80 kilograms, and bearing pin is after using distortion, and the impact that produces by impact block often can not overcome the frictional force between bearing pin and the axis hole, also just bearing pin can't be extracted, and causes dismantling ending in failure.
Summary of the invention
The utility model exists when at present implementing dismounting at the bearing pin of large-sized structural parts in order to solve wastes time and energy, dismantle problems such as difficult, and a kind of spiral pin removal is provided.
The utility model is to adopt following technical scheme to realize: spiral pin removal, comprise can be the directly or indirectly fixing leading screw of an end, be used to support leading screw and make it and wait to tear pin roll end face vertical also energy edge open and wait to tear open the mobile bracing frame of pin roll end face vertical direction (being leading screw self axial direction) with waiting to tear open screw on the bearing pin, the other end of leading screw is equipped with the nut that can offset with bracing frame, and the cooperation place of bracing frame and leading screw is in leading screw and waits to tear open the fixing end of bearing pin with between the nut.
During use, bracing frame is vertically stood on the surface that the large-sized structural parts bearing pin waits to tear open the place, and the leading screw end directly or indirectly fixed with waiting to tear open on the bearing pin screw, nut and the bracing frame adjusted on the leading screw offset, and bracing frame just in time is folded between large-sized structural parts and the nut; Then by spanner, nut on the turn leading screw produces pressure to bracing frame, and be passed on the large-sized structural parts by bracing frame, simultaneously, leading screw moves outward, outwards traction bearing pin to be torn open, like this, large-sized structural parts with wait to tear open bearing pin and be subjected to direction opposite effect power respectively, make to produce relative motion between bearing pin and the structural member, and then realize extracting of bearing pin.And in unloading process, realize lever principle, effectively reduced ARTIFICIAL FORCE used when bearing pin is dismantled by spanner.
The utility model is simple and reasonable for structure, and result of use is good, and is time saving and energy saving, is applicable to carry out the bearing pin dismounting when long-time used hydraulic support is reprocessed in the down-hole.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: the 1-large-sized structural parts; 2-bearing pin to be torn open; The 3-crossover sub; The 4-bracing frame; The 5-leading screw; The 6-nut; The 7-screw.
The specific embodiment
As shown in Figure 1, spiral pin removal, comprise can be the directly or indirectly fixing leading screw 5 of an end, be used to support leading screw 5 and make it and wait to tear bearing pin 2 end faces vertical also energy edge open and wait to tear open the mobile bracing frame 4 of bearing pin 2 end face vertical direction (being leading screw self axial direction) with waiting to tear open screw on the bearing pin 27, the other end of leading screw 5 is equipped with the nut 6 that can offset with bracing frame 4, and the cooperation place of bracing frame 4 and leading screw 5 is in leading screw 5 and waits to tear open the fixing end of bearing pin 2 with between the nut 6.
During concrete enforcement, leading screw 5 is used for and waits to tear open the end that screw 7 is fixed on the bearing pin 2 being equipped with crossover sub 3, described crossover sub 3 one ends are provided with and wait to tear open the screw thread that screw 7 is fixed on the bearing pin 2, the other end is fixed with leading screw 5 ends with demountable structure (as screw connection structure etc.), in order to indirect realization leading screw 5 ends with wait to tear open the fixing of screw 7 on the bearing pin 2.
The purpose that is provided with of crossover sub is: the bearing pin of 1, considering large-sized structural parts 1 is diversified in specifications, wait to tear open that there is inconsistency in the size of screw on the bearing pin, when implementing dismounting at the bearing pin of different size, only need to change crossover sub, and need not to change leading screw, make pin removal described in the utility model can be applicable to the bearing pin dismounting of different size; 2, in long-time use, the screw thread that screw cooperates on the bearing pin is fragile with waiting to tear open, and during the thread damage of crossover sub, the crossover sub that more renews gets final product, and need not to change leading screw, can effectively reduce the use cost of pin removal described in the utility model.
Described demountable structure is easy to for a person skilled in the art realize, and can realizes that for example: square toes are adopted in leading screw 5 ends with multiple structure, crossover sub 3 and the stiff end setting of leading screw 5 and the square inner bore of leading screw end square toes coupling;
Support frame as described above 4 also is easy to realize for a person skilled in the art, and can realize with multiple structure, wherein, the most easy structure is as follows: by gripper shoe, constitute with two pillars of gripper shoe vertical fixing, offer on the gripper shoe for leading screw and pass and be in through hole between two pillars.
