A kind of bont that the utility model provides; Comprise frame; Be arranged at the wireline reel of said frame, an end is connected with said wireline reel, the other end reaches the actuating device that is connected with said wireline reel with two hoisting ropes that the both sides of thing to be hoisted are connected respectively, and the both sides of said frame are respectively equipped with first angle pulley; Two said first angle pulleies are corresponding with two avris of thing to be hoisted respectively, and two said hoisting ropes are around in two said first angle pulleies respectively.
So be provided with, when the bont that utilizes the utility model to provide promotes object, for example; When promoting the LED display curtain, only need two hoisting ropes are connected in two side positions of thing to be hoisted, then start actuating device; Actuating device drives wireline reel and rotates; Because two hoisting ropes all are connected with wireline reel, so during the wireline reel rotation, two hoisting rope hoisting speeies unanimities.In addition; Because frame is provided with two first angle pulleies; And these two angle pulleies are corresponding with two avris of thing to be hoisted, promptly two hoisting ropes through two first angle pulley break-ins after, when two hoisting ropes promote thing to be hoisted; Two hoisting ropes act on that application force on the thing to be hoisted parallels and all perpendicular to plane, thing to be hoisted place, thing to be hoisted can not receive any extruding and be distorted in lifting process.Obviously, the bont that provides of the utility model can effectively be evaded the problem that thing to be hoisted is prone to be distorted in the handling process.
Description of drawings
Fig. 1 is a bont structural representation in the utility model specific embodiment.
The specific embodiment
The utility model provides a kind of bont, and it can effectively evade the problem that thing to be hoisted is prone to be distorted in the handling process.
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1, Fig. 1 is a bont structural representation in the utility model specific embodiment.
The bont that this specific embodiment provided comprises frame (not shown), wireline reel 11, two hoisting ropes 12 and actuating device (not shown)s.Wherein, wireline reel 11 is arranged on the frame, and an end of two hoisting ropes 12 all is connected on the wireline reel 11, and the other end of hoisting rope 12 is used to connect thing to be hoisted, and actuating device is connected with wireline reel 11 and rotates to drive wireline reel 11.Need to prove that the bont that this specific embodiment provided can be used for promoting the large LED screen, certainly, also can be applicable to promote other object, such as, large-scale propagating poster etc.
In addition; The bont that this specific embodiment provided; Two side positions of frame are respectively equipped with first angle pulley 13, and two first angle pulleies 13 are corresponding with two avris of thing to be hoisted, and two hoisting ropes 12 are around in two first angle pulleies 13 respectively.
So be provided with, when the bont that utilizes this specific embodiment to provide promotes object, for example; When promoting the LED display curtain, only need two hoisting ropes 12 are connected in two side positions of thing to be hoisted, then start actuating device; Actuating device drives wireline reel 11 and rotates; Because two hoisting ropes 12 all are connected with wireline reel 11, so during wireline reel 11 rotations, two hoisting rope 12 hoisting speeies unanimities.
In addition; Because frame is provided with two first angle pulleies 13; And these two first angle pulleies 13 are corresponding with two avris of thing to be hoisted, promptly two hoisting ropes 12 through two first angle pulley 13 break-ins after, when two hoisting ropes 12 promote thing to be hoisted; Two hoisting ropes 12 act on that application force on the thing to be hoisted parallels and all perpendicular to plane, thing to be hoisted place, thing to be hoisted can not receive any extruding and be distorted in lifting process.
Obviously, the bont that this specific embodiment provided can effectively be evaded the problem that thing to be hoisted is prone to be distorted in the handling process.
Need to prove, because two hoisting ropes 12 extend to two side positions of wireline reel 11, so during wireline reel 11 coiling hoisting ropes 12, hoisting rope 12 is prone to reel to wireline reel two side positions, and then causes hoisting rope 12 disengaging wireline reels 11.
Given this; The bont that this specific embodiment provided can specific as followsly be stated setting; Frame is provided with 14, two hoisting ropes 12 of wireline reel 11 corresponding two second angle pulleies and is around in two second angle pulleies 14 and two first angle pulleies 13 respectively successively.
Need to prove that the second covert pulley 14 is corresponding with wireline reel 11, mean that two second angle pulley 14 positions are between the plane, both ends of the surface place of wireline reel 11.Two hoisting ropes 12 are around in two second angle pulleies 14 and two first angle pulleies 13 respectively successively; Mean that two hoisting ropes 12 at first are around in second angle pulley 14 after being come out by wireline reel 11, then are connected through first angle pulley 13 and then with thing to be hoisted again.
So be provided with, when wireline reel 11 coiling hoisting ropes 12, hoisting rope 12 is positioned at the plane, place, two ends of wireline reel 11 all the time, promptly is positioned at all the time on the axis body of wireline reel, and then has effectively evaded the problem of hoisting rope 12 disengaging wireline reels 11.
In order to make hoisting rope 12 more clocklike be arranged on the wireline reel 11, can be provided with coiling groove (not shown) on the outer circumference surface of wireline reel 11, and the distribution of coiling groove spiral, two hoisting ropes 12 are wound in the coiling groove.
So be provided with, hoisting rope 12 can be arranged in along the coiling groove of spiral on the wireline reel 11 regularly, can effectively avoid hoisting rope 12 that the problem of entanglement takes place.
The bont that this specific embodiment provided, its hoisting rope 12 can be specially steel rope, certainly, also can be the hoisting rope of other type, such as, wick, only needs it to have sufficient intensity and promotes thing to be hoisted and get final product.
In addition, the bont that this specific embodiment provided, the actuating device of its wireline reel 11 can be specially motor, certainly, also can be the actuating device of other type, such as, HM Hydraulic Motors etc. only need it can provide enough power to get final product to drive the wireline reel rotation.
More than a kind of bont that the utility model provided has been carried out detailed introduction; Used concrete example among this paper the principle and the embodiment of the utility model are set forth, the explanation of above embodiment just is used to help to understand the method and the core concept thereof of the utility model.Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
