The utility model content
The purpose of this utility model provides a kind of electronic rail suspender, makes its lifting convenient, work safety, efficient.
The purpose of this utility model is achieved in that electronic rail suspender, comprise the connecting rod clamping device, this connecting rod clamping device comprises preceding upper connective plate, back upper connective plate, preceding hook plate and back hook plate, preceding upper connective plate and upper connective plate upper end, back are hinged through upper pin, preceding upper connective plate lower end and preceding hook plate upper end are hinged, back upper connective plate lower end is hinged with hook plate upper end, back, and preceding hook plate is hinged through lower bearing pin with hook plate middle part, back, and preceding hook plate and hook plate lower end, back are provided with the gib head that is used for the clamping rail; This electronic rail suspender also comprises the suspender frame, described suspender frame bilateral symmetry also is respectively equipped with two back plates, the connecting rod clamping device has two covers and is separately positioned between two back plates of both sides, corresponding upper pin two ends are installed in respectively on two back plates of a corresponding side, between two back plates of inboard, be horizontally disposed with and be useful on the support platform that motor and speed reducer is installed, the support platform downside is provided with limit and turns round device, limit is turned round the device lower end and is connected with screw rod, engagement is provided with nut seat on the screw rod, captives joint with corresponding lower bearing pin respectively in the nut seat two ends; Correspondence is provided with a vertical straight trough on two back plates of each side, and described lower bearing pin passes vertical straight trough.
During the utility model work, whole device is sling through the suspender frame, motor and speed reducer can be installed on support platform, when motor rotates, but limit is turned round the device transfer torque and is given screw rod, and screw rod rotates and drives nut seat and move up or down, and lower bearing pin is when longitudinally straight trough is transported lower bearing pin up or down and moved downward thereupon, corresponding gib head pitch smaller can be sling rail; When the lower bearing pin upward movement, the spacing between the corresponding gib head becomes big, rail can be unclamped.Compared with prior art, as long as the utility model is by electronic control, order about screw rod and do the rotation of corresponding rotation direction, can realize rail is clamped and decontroled, can lift by crane rail easily, the scene does not need personnel manually to open and tightens up gib head, it lifts by crane convenient, improve work efficiency, simultaneously, also improved safety.
For improving the screw axial stress-bearing capability, described screw rod is provided with two-way surface bearing, and described two-way surface bearing is bearing on the horizontally disposed stay bearing plate.The setting of stay bearing plate has improved screw axial stability.
Description of drawings
Fig. 1 is the utility model block diagram.
Fig. 2 is the utility model structural representation.
Wherein, 1 suspender frame, 2 medial branch boards, 3 lateral branch boards, 4 support platforms, 5 upper pins, 6 limits are turned round device, 7 screw rods, 9 vertical straight troughs, 10 lower bearing pins, 11 near switching control mechanism, 12 nut seats, 13 stay bearing plates, 14 two-way surface bearings, 15 gib heads, 16 back hook plates, hook plate before 17,18 back upper connective plates, 19 preceding upper connective plates.
The specific embodiment
As figure, electronic rail suspender, comprise the connecting rod clamping device, this connecting rod clamping device comprises preceding upper connective plate 19, back upper connective plate 18, preceding hook plate 17 and back hook plate 16, preceding upper connective plate 19 and upper connective plate 18 upper ends, back are hinged through upper pin 5, preceding upper connective plate 19 lower ends and preceding hook plate 17 upper ends are hinged, back upper connective plate 18 lower ends are hinged with hook plate 16 upper ends, back, preceding hook plate 17 is hinged through lower bearing pin 8 with hook plate 16 middle parts, back, preceding hook plate 17 and hook plate 16 lower ends, back are provided with the gib head 15 that is used for the clamping rail, and gib head 15 is connected as a single entity with corresponding preceding hook plate 17 and back hook plate 16; This device also comprises suspender frame 1, described suspender frame 1 bilateral symmetry also is respectively equipped with two back plates, be respectively the two lateral branch boards 3 that are positioned at the outside and be positioned at two inboard medial branch boards 2, the connecting rod clamping device has two covers and is separately positioned between the corresponding lateral branch board 3 and medial branch board 2 of both sides, corresponding upper pin 5 two ends are installed in respectively on the lateral branch board 3 and medial branch board 2 of a corresponding side, be horizontally disposed with between two medial branch boards 2 and be useful on the support platform 4 that motor and speed reducer is installed, support platform 4 downsides are provided with limit and turn round device 6, limit is turned round device 6 lower ends and is connected with screw rod 7, engagement is provided with nut seat 12 on the screw rod 7, and nut seat 12 two ends are connected with corresponding lower bearing pin 10 respectively; Correspondence is provided with a vertical straight trough 9 on two back plates of each side, and described lower bearing pin 10 passes vertical straight trough 9 of a corresponding side separately.Also be provided with two-way surface bearing 14 on the screw rod 7, described two-way surface bearing 14 is bearing on the horizontally disposed stay bearing plate 13.
