Abstract
The utility model relates to a manual lifting supporting device. The manual lifting supporting device comprises an adjusting seat, a hole is formed in the periphery of the adjusting seat, and a positioning handle is connected in the hole in an inserting mode. A turning nut is arranged in the adjusting seat, and a thrust ball bearing is arranged on the turning nut. One end of an adjusting lead screw sequentially penetrates through the turning nut and the thrust ball bearing and is in threaded connection with the adjusting seat, and the other end of the adjusting lead screw sequentially penetrates through a connection plate and a roller seat. The connection plate is fixedly connected with the roller seat, at least two symmetrical grooves are formed in the roller seat, roller rotating shafts are embedded in the grooves, and rollers are arranged outside the roller rotating shafts. According to the manual lifting supporting device, the nut is driven to rotate through rotation of the handle, rotating motion is changed into vertical motion of the adjusting lead screw, therefore the roller seat is driven to carry out synchronous motion along with the vertical motion of the adjusting lead screw, and the purpose that a workpiece support is in a horizontal state can be achieved.
Description
Technical field
The utility model relates to fastening, relates in particular to hand-operated lifting support device.
Background technology
In the prior art, when the straight girth welding of the enterprising line pipe part of positioner, all need be at positioner device chuck, by chuck pipe fitting is clamped, drive its revolution and process, but when processing during than long pipe fittings, only the clamping by chuck can't satisfy pipe fitting and keeps horizontal level, makes the welding job difficulty.
I am at the requirement in above-mentioned, provide a kind of rational in infrastructure, the easy to operate carrying roller mechanism that manually heightens.Its cardinal principle is by the rotation nut, and screw rod is done movement in vertical direction, drives the roller mount knee-action at screw rod top, and roller is made and can be regulated, and is suitable for the workpiece of different-diameter.
The utility model content
The applicant provides a kind of simple in structure, easy to operate hand-operated lifting support device at these shortcomings in the above-mentioned existing production.
The technical scheme that the utility model adopts is as follows:
Hand-operated lifting support device comprises adjustment seat, and the periphery of adjustment seat has the hole, the position fixing handle of pegging graft in the hole; In adjustment seat, install rotating nut, install thrust ball bearing on the rotating nut; An end of regulating screw mandrel runs through rotating nut, thrust ball bearing in proper order and is threaded with adjustment seat, the other end of regulating screw mandrel runs through connecting plate, roller mount in proper order, connecting plate and roller mount are affixed, at least symmetry has two grooves on roller mount, chimeric roller wheel shaft in the groove, the peripheral unit roller of roller wheel shaft.
Its further technical scheme is:
Have the groove that to peg graft with position fixing handle on the described adjusting screw mandrel;
Be provided with the rocking bar that the position is mutually 90 ° in the periphery of described rotating nut, an end device handle ball of rocking bar;
The beneficial effects of the utility model are as follows:
The utility model is simple in structure, easy to operate, rotate by the rotary handle drive nut, convert moving up and down of adjusting screw mandrel with rotatablely moving to, thereby drive roller mount with regulating being synchronized with the movement up and down of screw mandrel, be in horizontal state to reach workpiece support; Simultaneously the roller on the roller mount can be on roller mount free conversion gear, can satisfy the demand of the workpiece of different size.
Description of drawings
Fig. 1 is perspective view of the present utility model.
Fig. 2 is the assembling schematic diagram of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1 and Figure 2, the utility model comprises adjustment seat 1, and the periphery of adjustment seat 1 has kidney slot 101, and being provided with in the kidney slot 101 can be for the perforate 102 of position fixing handle 2 grafting, and turning handle 2 is affixed by securing member 103 and adjustment seat 1; Device rotating nut 3 in adjustment seat 1, suit thrust ball bearing 10 on the rotating nut 3, thrust ball bearing 10 play supporting role; The periphery of rotating nut 3 is provided with the rocking bar 8 that the position is mutually 90 °, an end device handle ball 9 of rocking bar 8.An end of regulating screw mandrel 4 runs through rotating nut 3, thrust ball bearing 10 in proper order and is threaded with adjustment seat 1, the other end of regulating screw mandrel runs through connecting plate 12, roller mount 5 in proper order, connecting plate 12 is affixed by securing member with roller mount 5, at least symmetry has two groove 501(as shown in Figure 2 on roller mount 5, in the utility model, groove 501 is 4), chimeric roller wheel shaft 6 in the groove 501, the peripheral unit roller 7 of roller wheel shaft 6.Also having on adjusting screw mandrel 4 can be for the groove 401 of position fixing handle 2 grafting, and position fixing handle 2 is plugged in the 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 prevents that rotating nut 3 from falling.
The concrete course of work of the present utility model 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, according to the length of pipe fitting, roller 7 is placed suitable gear then, the while is according to the clamping height of pipe fitting, by handle ball 9 rotation rotating nuts 3, because the guide effect of position fixing handle 2, regulating 4 of screw mandrels when making rotation rotating nut 3 can move both vertically up and down, and can not rotate with rotating nut 3.
When regulating screw mandrel 4 risings, owing to regulate an end device connecting plate 12 of screw mandrel 4, and connecting plate 12 is fixedlyed connected with roller mount 5 by securing member, make roller do 5 with regulating screw mandrel 4 risings, after reaching the required clamping height of pipe fitting, can finish the supporting to pipe fitting, make pipe fitting keep level.
The utility model is simple in structure, easy to operate, rotate by the rotary handle drive nut, convert moving up and down of adjusting screw mandrel with rotatablely moving to, thereby drive roller mount with regulating being synchronized with the movement up and down of screw mandrel, be in horizontal state to reach workpiece support; Simultaneously the roller on the roller mount can be on roller mount free conversion gear, can satisfy the demand of the workpiece of different size.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model institute restricted portion is referring to claim, and under the situation of basic structure of the present utility model, the utility model can be done any type of modification.
