Abstract
The utility model relates to a shaft pin type overload limit device of an electric hoist trolley, which mainly comprises an overload display component, a wedge sleeve as well as wire ropes and a wire rope clamp, a shaft pin type overload limiter, brackets, a shaft sleeve and a hanging board, wherein through arranging brackets on a casing of an electric hoist, two ends of the shaft pin type overload limiter and an end board are connected and mounted on one of the brackets; and through arranging the shaft sleeve and the hanging board, and connecting the shaft sleeve and the hanging board mutually, the shaft sleeve can be connected with the outer surface of the shaft pin type overload limiter in a sleeving way and is connected with the wedge sleeve through the hanging board, and the shaft pin type overload limiter is not directly in contact with the wire ropes, so that friction can be prevented from generating and the mutual abrasion can be prevented from undergoing between the overload limiter and the wire ropes, and overload accidents caused by the malfunction of the overload limiter are avoided. The technical scheme is simple in structure and implementation and convenient for installation and maintenance, has very ideal roles of preventing the overload limiter from malfunction and eliminating accident potentials.
Description
Technical field:
The utility model relates to mechanical equipment, especially the electric block dolly in the lifting equipment.
Background technology:
Always, for safety, prevent that the electric block dolly is accidents caused because of overloading, on the electric block dolly, be provided with load limiter.Because playing a role clearly and intuitively seeing overload capacity of its overload restriction in the course of time, just become one of indispensable engineering factor on the electric block dolly.
But the existing load limiter that uses on the electric block dolly is mounted in the side-compression load limiter on the steel rope; Because steel rope and side-compression load limiter rub easily; Be worn each other, will become flexible between the pressure sling of side-compression load limiter and the steel rope, not only can reduce the service life of steel rope and load limiter, and can be because of the malfunctioning initiation gross overload accident of load limiter; So; Existing side-compression load limiter obviously exists gross overload accident hidden danger, is not suitable for using on the electric block dolly.
Summary of the invention:
The purpose of the utility model provides a kind of electric block dolly axial pin type overload restraint device; Its objective is such realization: integral body comprises overload display module, cover of wedge and steel rope and wire rope grip, has also comprised the axle sleeve and the link plate of axial pin type load limiter, the support that is arranged on the electric block shell, phase interconnected body; To be connected with the electric block shell, support is arranged on the electric block with the end plate of one side and the limit of connecting panel; Axle sleeve is enclosed within axial pin type load limiter outside, and link plate and cover of wedge are with spool being connected and with the end of pin pin in axle; The axial pin type load limiter is connected with two end plates with two ends and is arranged on the support; Survey and transmit the overload sensor of information of axial pin type load limiter with joint being used to of being connected with data line in the overload display module, be connected an end of axial pin type load limiter.
Owing to adopted such scheme,, just can the axial pin type load limiter be mounted on the support with two ends and end plate through on the electric block shell, support being set; Through axle sleeve and link plate are set; And, just can axle sleeve be enclosed within axial pin type load limiter outside, and be connected with cover of wedge with link plate with axle sleeve and link plate interconnected body mutually; The axial pin type load limiter is not directly contacted with steel rope; Just can prevent to rub between load limiter and the steel rope, worn and torn each other, avoid load limiter malfunctioning, cause gross overload accident.This technical scheme, simple in structure, implement easily, not only installation and maintenance are convenient, and prevent that load limiter effect malfunctioning and elimination accident potential is all very desirable.
Description of drawings:
Accompanying drawing is an electric block dolly axial pin type overload restraint device structural representation.
Among the figure: 1, connecting panel 2, support 3, axial pin type load limiter 4, sensor 5, read-out 6, instrument 7, electric wire 8, joint 9, data line 10, electric block shell 11, end plate 12, axle sleeve 13, link plate 14, nut 15, clevis bolt 16, fixture block 17, steel rope 18, cover of wedge 19, axle 20, cut son 21, end plate
The specific embodiment:
Below in conjunction with accompanying drawing and embodiment, the utility model is described further.
Electric block dolly axial pin type overload restraint device, as shown in the figure:
Integral body comprises overload display module, cover of wedge 18 and steel rope 17 and wire rope grip, has also comprised axial pin type load limiter 3, is arranged on the support 2 of electric block shell 10, the axle sleeve 12 and the link plate 13 of phase interconnected body.
Overload display module wherein, comprise sensor 4, data line 9, joint 8, be provided with read-out 5 instrument 6, can lead to the electric wire 7 of control housing, the two ends of data line 9 are connected with sensor 4, the joint 8 of being located at instrument 6 respectively.
Wire rope grip wherein comprises clevis bolt 15, nut 14, fixture block 16, can penetrate steel rope 17 between fixture block 16 and the clevis bolt 15, fixture block 16 is enclosed within on the clevis bolt 15, and nut 14 is twisted in the two ends of clevis bolt 15.
Support 2 wherein is provided with end plate 11/21 and connecting panel 1, and connecting panel 1 is connected with end plate 11/21 with two ends and is set directly between the end plate 11/21, with this phase interconnected body.
To be connected with electric block shell 10, support 2 is arranged on the electric block with the end plate 11/21 of one side and the limit of connecting panel 1;
Axial pin type load limiter 3 is connected with two end plates 11/21 with two ends and is arranged on the support 2;
Survey and transmit the overload sensor 4 of information of axial pin type load limiter 3 with joint 8 being used to of being connected with data line 9 in the overload display module, be connected an end of axial pin type load limiter 3.
