Along with the continuous development of elevator technology, load-carrying unit can be designed to wrapped up by elastomeric material.The benefit of doing like this is that the drive wheel diameter of towing machine is can design-calculated less, thereby causes the drive torque of towing machine less, and the volume of towing machine also can reduce, and the layout of elevator device is more flexible; And because flexible material parcel, the vibration of elevator device and noise will reduce greatly, and the overall performance of elevator device is improved.But because flexible material parcel requires terminating set must be designed to give load-carrying unit littler compression effort like this; Otherwise elastomeric material will be crushed or creep, thereby makes load-carrying unit fine motion in socket, causes terminating set to lose efficacy, and brings on a disaster to elevator device.
For this reason, Chinese invention patent specification sheets CN1211272C discloses a kind of terminating set of lift appliance on (July 20 2005 day for announcing).But, the compression effort that this terminating set just becomes load-carrying unit with the pressure-bearing Design of length of voussoir the permission of elasticity lapping with range of pressure in.Will make the pressure of load-carrying unit inhomogeneous like this, thereby possibly cause the part of load-carrying unit to produce very large compression effort, the crushing or the creep of elasticity lapping occur, make terminating set lose efficacy.
Summary of the invention
The technical matters that the present invention will solve provides a kind of terminating set that is used for lift appliance, its ability automatic compensation voussoir position in socket; Make the pressure of load-carrying unit even, increase the service life; This terminating set is simple in structure, reliable simultaneously.
For solving the problems of the technologies described above, the terminating set that is used for lift appliance of the present invention comprises socket, voussoir, two strut members; Said socket has a strong point; Said voussoir is arranged between two strut members; Said voussoir has two first contoured surfaces that form an angle and be oppositely arranged with its center; Said two strut members have and corresponding second contoured surface of first contoured surface; Clamping promotes the load-carrying unit of lift appliance between said first and second contoured surface; Said voussoir and strut member at least partly are positioned at the inside of socket; Said each strut member is provided with at least one contact profile, and this contact profile is between strut member and socket, and said contact profile makes said two strut members in socket, to rotate, and said voussoir rotates under said two strut members drive; After load-carrying unit bore external force, said two strut members and said voussoir turned on the strong point position basically in a straight line of said load-carrying unit and said socket.
Owing to adopt said structure, make said two strut members and voussoir in socket, to rotate freely, automatically adjust the position of voussoir in socket, guarantee simultaneously on the strong point position basically in a straight line of said load-carrying unit and said socket.It is reliable to do the contact stabilization that can guarantee between two strut members and the voussoir like this, makes the face pressure of load-carrying unit very even, is very beneficial for having the load-carrying unit of elastomeric material parcel.
Description of drawings
Below in conjunction with accompanying drawing and preferred embodiment the present invention is done further detailed explanation:
Fig. 1 is the terminating set one embodiment front view that is used for lift appliance of the present invention;
Fig. 2 is the lateral plan of Fig. 1.
The specific embodiment
Like Fig. 1, shown in 2, in one embodiment of this invention, said terminating set comprises strut member 1, strut member 2, voussoir 3, socket 4.This terminating set utilizes bearing pin 5, attaching parts 6, screw rod 7, spring mounting seat 8, spring 9, spring mounting seat 10, nut 11 and spring cotter 12 to be connected on other parts of elevator, and wherein the strong point 18 of socket 4 is rotationally connected with bearing pin 5.
Said voussoir 3 has two and forms an angle with its center (line of centers that indicates referring to Fig. 1), first contoured surface 13 that is oppositely arranged, and the scope of this angle is 5 °～15 °.The positive pressure that load-carrying unit is received in such angular range is little, thereby makes the face of load-carrying unit press less.
In a preferred embodiments, the angle that said voussoir 3 has between 13, two first contoured surfaces 13 of two symmetrically arranged first contoured surfaces is 10 °～30 °.Voussoir 3 wide ends connect first contoured surface 13 at two ends through arc surface.
Said voussoir 3 is between strut member 1 and strut member 2, and said voussoir 3, strut member 1 and strut member 2 at least partly are positioned at the inside of socket 4; Voussoir 3, strut member 1 and strut member 2 are positioned at the inside of socket 4 fully in the embodiment shown in fig. 1.The structure and shape of strut member 1,2 is roughly the same.
Described strut member 1,2 has first contoured surface, 13 corresponding second contoured surfaces 14 with voussoir 3 respectively.At least be provided with a contact profile between each strut member 1,2 and the socket 4, wherein the contact profile between strut member 1 and the socket 4 is 15, and the contact profile between strut member 2 and the socket 4 is 17. Contact profile 15,17 is separately positioned on the side of strut member 1 and strut member 2, perhaps is separately positioned on the side and the bottom of strut member 1 and strut member 2.Each contact profile 15,17 is one section circular arc, and their center of circle is different.On said socket 4, be provided with the circular arc suitable, make it to contact with contact profile 15,17 with contact profile 15,17; Certainly contacted with contact profile 15,17 on said socket 4 also can be a plane.When contact profile 15,17 is separately positioned on the bottom of strut member 1,2, should make the bottom circular arc of socket 4 identical with the arc radius of contact profile 15,17.
Said contact profile 15,17 makes said two strut members 1,2 in said socket 4, to rotate; And said two strut members, 1,2 center of turns different (position that label 21 guides among Fig. 1 is the center of turn of strut member 1, and the position that label 20 guides is the center of turn of strut member 2).Certainly, the center of turn of two strut members 1,2 also can be designed to identical, and center of turn is positioned at the center of voussoir 3.Like this because contact profile 15,17 makes strut member 1,2 and voussoir 3 in socket 4, rotate together; Simultaneously can the said load-carrying unit of strict guarantee and the strong point 18 position basically in a straight line of said socket 4 on; The part in compression distortion strict conformance of said like this load-carrying unit, and face is pressed identical.
As stated, owing to adopt above-mentioned structure, voussoir 3, strut member 1, the very firm position relation of formation between 2.When load-carrying unit from the opening of socket 4 bottoms get into voussoir 3 and strut member 1, between 2, during around voussoir 3, the pressure that load-carrying unit receives is very even, makes that so well guaranteed the service life of load-carrying unit.If very reasonable with the pressurized Design of length of voussoir 3 simultaneously can make the face pressure-controlled of load-carrying unit in unusual reasonable levels, this point is for extremely important by the load-carrying unit of elastomeric material parcel.It is broken that it will make that elastomeric material can not be extruded, and destructive phenomenons such as creep or cold flow can not occur simultaneously, well guaranteed the service life of terminating set.Certainly for traditional load-carrying unit good effect is arranged also, because the pressure of load-carrying unit is even, it is very big local pressure can not occur, thereby causes the possibility of load-carrying unit local fracture.
More than, the present invention has been carried out detailed explanation, but protection scope of the present invention is not limited to described embodiment through embodiment.Under the situation that does not break away from the principle of the invention, those skilled in the art also can make many distortion and improvement, and these also should be regarded as protection scope of the present invention.
