Utility model content
The purpose of this utility model is to provide one can regulate height, and wicking height scope is large, avoids hidden danger, low cost of manufacture, long service life, the jack assembly of increasing work efficiency, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of jack assembly, comprises base, lifting bar, channel-section steel cross-arm and jack; Described base is arranged on lifting bar lower end, and lifting bar is positioned at base center and perpendicular setting; Lifting bar bottom is provided with locking lever, and locking lever upper end and lifting bar are hinged, and the lower end of locking lever is provided with the setting that to be articulated and connected in the middle part of locating rack; Positioning seat is provided with below described locating rack; Cardan wheel is provided with below described base; Described lifting bar top horizontal link slot steel cross-arm, channel-section steel cross-arm bottom is connected to supporting pin, and lifting bar top is inserted in supporting pin; Described channel-section steel cross-arm front end arranges track, and track is built-in with sliding machine, and sliding machine normal thread connects montant, and montant upper end connects height regulating handle; In described montant lower end, corresponding channel-section steel cross-arm place is provided with transverse concave groove, and montant connects iron chains through transverse concave groove, and iron chains lower end connects jack.
Further: described height regulating handle setting range is 0.5-1 rice.
Further: the height adjustment range of described height regulating handle is less than lifting bar.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model passes through cardan wheel, random movement, and operate locking lever and locating rack is fallen and supports on the ground, then regulate height by lifting bar, after finishing using, regain base, again regulate locking lever, locating rack is packed up, the features such as it is reasonable in design, structure is simple, easy to use, function admirable, practicality, arbitrarily can regulate height, wicking height scope is large, avoids staff's high-altitude suspension and the accident potential that brings;
2, in the utility model, sliding machine can to move with jack according to stretching process and needs short range to move freely, the height of height adjustment handle motor-driven adjustment jack among a small circle, application is convenient, low cost of manufacture, long service life, can not damage easily, floor area is little, improve the stretch-draw work efficiency of operator, reduce the tension operation time.
Accompanying drawing explanation
Fig. 1 is the structural representation of jack assembly.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of jack assembly, comprises base 1, lifting bar 2, channel-section steel cross-arm 5 and jack 9; Described base 1 is arranged on lifting bar 2 lower end, and lifting bar 2 is positioned at base 1 center and perpendicular setting; Lifting bar 2 bottom is provided with locking lever 3, and locking lever 3 upper end and lifting bar 2 are hinged, and the lower end of locking lever 3 is provided with the setting that to be articulated and connected in the middle part of locating rack 4; Positioning seat 11 is provided with below described locating rack 4; Cardan wheel 12 is provided with below described base 1; In work, by cardan wheel 12, arbitrarily movement, and operate locking lever 3 and locating rack 4 is fallen and supports on the ground, then regulate height by lifting bar 2, after finishing using, regain base 1, again regulate locking lever 3, locating rack 4 is packed up, it is reasonable in design, structure is simple, easy to use, function admirable, the feature such as practicality, arbitrarily can regulate height, wicking height scope is large, avoids staff's high-altitude suspension and the accident potential that brings; Described lifting bar 2 top horizontal link slot steel cross-arm 5, channel-section steel cross-arm 5 bottom is connected to supporting pin 13, and lifting bar 2 top is inserted in supporting pin 13; Described channel-section steel cross-arm 5 front end arranges track, track is built-in with sliding machine 6, and sliding machine 6 normal thread connects montant 10, and montant 10 upper end connects height regulating handle 7, height regulating handle 7 setting range is 0.5-1 rice, and the height adjustment range of height regulating handle 7 is less than lifting bar 2; In described montant 10 lower end, corresponding channel-section steel cross-arm 5 place is provided with transverse concave groove, and montant 10 connects iron chains 8 through transverse concave groove, and iron chains 8 lower end connects jack 9; In work, sliding machine 6 can to move with jack 9 according to stretching process needs short range to move freely, the height of height adjustment handle 7 motor-driven adjustment jack among a small circle, application is convenient, and manufacturing cost can save 30%, and device can forever use, can not damage easily, floor area is little, improves the stretch-draw work efficiency of operator, reduces the tension operation time.
