Embodiment
Be described in detail embodiment of the present utility model below, its sample table shows in the accompanying drawings.Be described to explain the utility model to embodiment below with reference to the accompanying drawings.
Fig. 2 is the structural representation of the vertical view according to horizontal loop of the present utility model; Fig. 3 is the structural representation of the front view of horizontal loop in Fig. 2.
Specifically describe according to horizontal loop of the present utility model referring to Fig. 2, Fig. 3.Horizontal loop comprises winding plant, wireline 23, loop trolley 25, first travelling block 26, second travelling block 27 and fixed pulley 22, winding plant comprises drive unit 28 and reel 21, wherein, reel 21 can be double hoisting reel, wireline 23 coiling is on reel 21, first travelling block 26, second travelling block 27 and fixed pulley 22 are all between reel 21 and loop trolley 25, first travelling block 26, second travelling block 27 is arranged on the both sides, front end of loop trolley 25 symmetrically, and the first travelling block 26, relative position relation between second travelling block 27 and loop trolley 25 is fixed, such as, each travelling block can all be fixed on loop trolley 25.Fixed pulley 27 is fixed on winding plant, and from the side of reel 21, successively, order coiling first travelling block 26, fixed pulley 22 and the second travelling block 27 are also finally fixed on the opposite side of reel 21 wireline 23.Make reel 21 rotate folding and unfolding wireline 23 by drive unit 28, and then drive loop trolley 25 to seesaw together with two travelling block 26,27.
In the present embodiment, double hoisting reel is formed uniformly and places the grooving of wireline 23, the two ends of wireline 23 symmetrically coiling in the grooving of double hoisting reel, to make the stress balance at the two ends of wireline 23.Wireline 23 can from the grooving at middle part towards zygomorphy ground coiling, also can from the grooving of both sides towards middle part coiling symmetrically, preferably, when horizontal loop is entry loop, wireline 23 is from middle part towards zygomorphy ground coiling, when being in full cover position (position namely during normal production) to make entry loop, the moment of flexure that reel 21 is subject to is less, thus optimizes the stressed of reel 21; When horizontal loop is outlet looping, wireline 23 is coiling symmetrically from both sides towards middle part, with make outlet looping be in empty set position (namely normal produce time position) time, the moment of flexure that reel 21 is subject to is less.
In addition, also carrying roller 24 can be set in the front of travelling block 26,27, to support or to hold the wireline 23 of coiling travelling block 26,27, ensure the height of wireline 23.In addition, drive unit 28 can be electric motor and step-down gear.
Describe the working process of horizontal loop below with reference to accompanying drawings in detail.
Fill in cover process at horizontal loop, drive unit 28 makes reel 21 be subject to forward making a concerted effort of (right side namely in Fig. 2) with movable reel 21 thus (being namely seen as clockwise from the view of Fig. 3) rotates clockwise, wireline 23 along the grooving extended from centre to both sides symmetrically coiling on reel 21, along with the coiling of wireline 23, wireline 23 pulls forward travelling block 26 and 27, and then pull loop trolley 25 to travel forward, along with the loop trolley of front end travels forward successively, steel band can enter horizontal loop more.Now, owing to there are two travelling block 26, 27, make travelling block 26, the stressed half of making a concerted effort for forward direction on the wireline 23 at 27 two ends, and when loop trolley 25 moves forward predetermined distance, each travelling block all moves forward described predetermined distance, namely the equal coiling in the both sides of reel 21 has the wireline 23 of the length of the described predetermined distance of two times, the translational speed of wireline 23 has become original two times, in addition, because the two ends of reel 21 are fixed, when entry loop is in full cover position, the pulling force of wireline 23 pairs of reels is positioned at the two ends place of reel 21, therefore, the moment of flexure reel of entry loop being subject to from middle part towards the mode of both sides coiling wireline 23 is less, similarly, (not shown) when outlet looping is in empty set position, the pulling force of wireline 23 pairs of reels 21 is positioned at the two ends place of reel 21, and therefore, the moment of flexure reel of outlet looping being subject to from both sides towards the mode of middle part coiling is less.
Put in cover process at entry loop, because steel band itself has backward the pulling force in (left side namely in Fig. 2) always, therefore when drive unit 28 provides less motivating force, loop trolley 25, travelling block 26,27 and reel 21 be subject to backward make a concerted effort, reel 21 counterclockwise (being namely seen as counterclockwise from the view of Fig. 3) rotates, wireline 23 is released from reel 21, loop trolley 25 moves backward, along with the loop trolley of front end moves successively backward, steel band can leave horizontal loop and enter in production process subsequently.
Therefore, according to the beneficial effects of the utility model be: loop trolley is in operational process, under the effect of travelling block and fixed pulley, wireline is symmetrical in drum center line all the time and runs, due to the medullary ray that drum center line is also loop trolley simultaneously, so the pulling force of both sides wireline to reel is symmetrical.In addition, wireline, by the coiling of a fixed pulley, two travelling block, makes the stressed of wireline alleviate as original half, and the translational speed of wireline becomes original twice simultaneously, therefore the step-down gear that speed can be selected smaller.In addition, the fixed form of the wireline of entry loop is improved to middle part wireline being originated in reel, the moment of flexure that reel is subject to is less, therefore, the stressed of wireline and reel can be optimized by the layout improving pulley and wireline, thus more economic wireline and step-down gear can be selected, structure is simple, economically feasible, ensure that the high-speed stable running of Long Distances horizontal loop, decreases cost consumption.
Although show and described embodiments more of the present utility model, but, it should be appreciated by those skilled in the art, when not departing from principle of the present utility model and spirit, can make change in these embodiments, scope of the present utility model is by claim and equivalents thereof.
