Abstract
The manual lifting and supporting device which comprises an adjusting seat. Holes are formed on the periphery of the adjusting seat, positioning handles are connected in the holes in an inserted manner, a rotating nut is arranged in the adjusting seat, a thrust ball bearing is arranged on the rotating nut, one end of an adjusting screw sequentially penetrates the rotating nut and the thrust ball bearing to be in threaded connection of the adjusting seat while the other end of the adjusting screw sequentially penetrates a connecting plate and a roller seat, the connecting plate is fixedly connected with the roller seat, at least two grooves are symmetrically formed in the roller seat, a roller rotating shaft is embedded in each of the grooves, and a roller is arranged on the periphery of each roller rotating shaft. The nut is driven to rotate by a rotating handle, and rotating motion is converted into up-down motion of the adjusting screw so as to drive the roller seat to move synchronously along with up-down motion of the adjusting screw, so that a workpiece is supported horizontally.
Description
Technical field
The present invention relates to fastening, relate in particular to hand-operated lifting support device.
Background technology
In prior art, when the straight girth welding of the enterprising line pipe part of positioner, all need on positioner, install chuck, by chuck, pipe fitting is clamped, drive its revolution and processed, but, when processing than long pipe fittings, only the clamping by chuck can't meet pipe fitting maintenance horizontal level, makes the welding job difficulty.
I am for the requirement in above-mentioned, provide a kind of rational in infrastructure, the easy to operate carrier roller mechanism of manually heightening.Its cardinal principle is by rotating nut, and screw rod is done to movement in vertical direction, drives the roller mount knee-action at screw rod top, and roller is made and can be regulated, the workpiece of applicable different-diameter.
Summary of the invention
The applicant, for these shortcomings in above-mentioned existing production, provides a kind of simple in structure, easy to operate hand-operated lifting support device.
The technical solution adopted in the present invention is as follows:
Hand-operated lifting support device, comprise adjustment seat, and the periphery of adjustment seat has grafting position fixing handle in ，Yu hole, hole; Install rotating nut in adjustment seat, install thrust ball bearing on rotating nut; An end of regulating screw mandrel sequentially runs through rotating nut, thrust ball bearing and is threaded with adjustment seat, the other end of regulating screw mandrel sequentially runs through connecting plate, roller mount, connecting plate and roller mount are affixed, on roller mount, at least symmetry has two grooves, chimeric roller wheel shaft in groove, the peripheral unit roller of roller wheel shaft.
Its further technical scheme is:
Have the groove that can peg graft with position fixing handle on described adjusting screw mandrel;
The outer rocking bar that position is mutually 90 °, the end device handle ball of rocking bar of being arranged with in described rotating nut;
Beneficial effect of the present invention is as follows:
The present invention is simple in structure, easy to operate, by the rotation of rotary handle drive nut, converts to rotatablely moving and regulates moving up and down of screw mandrel, thereby drive roller mount with regulating being synchronized with the movement up and down of screw mandrel, to reach the state of workpiece support in level; Roller on roller mount can freely convert gear on roller mount simultaneously, can meet the demand of the workpiece of different size.
The accompanying drawing explanation
Fig. 1 is perspective view of the present invention.
The assembling schematic diagram that Fig. 2 is Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1 and Figure 2, the present invention includes and comprise adjustment seat 1, the periphery of adjustment seat 1 has kidney slot 101, is provided with the perforate 102 that can peg graft for position fixing handle 2 in kidney slot 101, and turning handle 2 is affixed by securing member 103 and adjustment seat 1; At the interior device rotating nut 3 of adjustment seat 1, suit thrust ball bearing 10 on rotating nut 3, thrust ball bearing 10 play supporting role; The outer rocking bar 8 that position is mutually 90 °, the end device handle ball 9 of rocking bar 8 of being arranged with of rotating nut 3.An end of regulating screw mandrel 4 sequentially runs through rotating nut 3, thrust ball bearing 10 and is threaded with adjustment seat 1, the other end of regulating screw mandrel sequentially runs through connecting plate 12, roller mount 5, connecting plate 12 is affixed by securing member with roller mount 5, on roller mount 5, at least symmetry has two groove 501(as shown in Figure 2, in the present invention, groove 501 is 4), the interior chimeric roller wheel shaft 6 of groove 501, the peripheral unit roller 7 of roller wheel shaft 6.Also have the groove 401 that can peg graft for position fixing handle 2 on adjusting screw mandrel 4, position fixing handle 2 is plugged in groove 401, makes in rotation rotating nut 3, regulates 4 of screw mandrels and can do elevating movement, and can not rotate with rotating nut 3.Returning apparatus holding screw 11 on adjustment seat 1, prevent that rotating nut 3 from falling.
Specific works process of the present invention is as follows:
As shown in Figure 2, utilize the chuck of positioner to fix an end of pipe fitting, roller mount 5 is reduced to minimum point, then according to the length of pipe fitting, roller 7 is placed in to suitable gear, the while is according to the clamping height of pipe fitting, by handle ball 9 rotation rotating nuts 3, due to the guide effect of position fixing handle 2, regulating 4 of screw mandrels when making rotation rotating nut 3 can move up and down vertically, and can not rotate with rotating nut 3.
When regulating screw mandrel 4 rising, due to an end device connecting plate 12 of regulating screw mandrel 4, and connecting plate 12 is fixedly connected with roller mount 5 by securing member, making roller do 5 rises with regulating screw mandrel 4, after reaching the required clamping height of pipe fitting, can complete the supporting to pipe fitting, make pipe fitting keep level.
The present invention is simple in structure, easy to operate, by the rotation of rotary handle drive nut, converts to rotatablely moving and regulates moving up and down of screw mandrel, thereby drive roller mount with regulating being synchronized with the movement up and down of screw mandrel, to reach the state of workpiece support in level; Roller on roller mount can freely convert gear on roller mount simultaneously, can meet the demand of the workpiece of different size.
Above description is explanation of the invention, is not that limited range of the present invention is referring to claim, in the situation that, without prejudice to basic structure of the present invention, the present invention can do any type of modification to the restriction of invention.
