Detailed description of the invention

Referring to figs. 1 through Fig. 4, this utility model is described further.

A kind of cement mortar plain bumper, including platform dish 13 and clamping bar 1, described dish 13 is provided with the governor motion for regulating clamping bar 1 longitudinally lifting, described governor motion is lead screw transmission mechanism, by lead screw transmission mechanism, gyration conversion is linearly moved, regulating the adjustable height of clamping bar 1, precision is higher.

As shown in Figure 1, described lead screw transmission mechanism includes elevator 2 and stud 3, one end of described stud 3 is fixing with platform dish 13 to be connected, the upper end of described elevator 2 and the lower end of clamping bar 1 are fixed, the upper end of described elevator 2 is welded with the lower end of clamping bar 1, prevent cement mortar plain bumper in the process of vibration, clamping bar 1 and elevator 2 depart from, described elevator 2 is provided with the screw matched with stud 3, described elevator 2 is sheathed on stud 3, utilize screw next with coordinating of stud 3, by rotation and lifting block 2, the female thread in elevator 2 screw is made to be subject on stud 3 externally threaded restriction, elevator 2 is made to move up and down on stud 3, thus driving the lifting of clamping bar 1.

In the prior art, owing to the governor motion of two column sleeves separates, being difficult to hold the altitude mixture control of column sleeve to consistent by manpower, user generally requires after having regulated column sleeve height and ensures that two column sleeves are highly consistent by external force such as gage, operates very constant.

As described in Figure 2, described dish 13 is provided with the first column 6, second column 7, first column sleeve 4 and the second column sleeve 5, described first column 6 is provided with the first movable block 8, described second column 7 is provided with the second movable block 9, the upper end of described first movable block 8 and the lower end of the first column sleeve 4 are fixed, the upper end of described second movable block 9 and the lower end of the second column sleeve 5 are fixed and are prevented cement mortar plain bumper in the process of vibration, movable block departs from column sleeve, affect die sleeve and cement mortar is tried the fixed effect of film, described first movable block 8 is set on the first column 6 and threadeds with the first column 6, described second movable block 9 is set on the second column 7 and threadeds with the second column 7, screw thread on described first column 6 and the screw thread on the second column 7 are consistent, prevent that the screw thread specification on two columns is different to be caused when two movable blocks rotate identical angle time, the height of two movable block liftings is different to some extent.

As shown in Figure 3 to Figure 4, described dish 13 is additionally provided with the link gear for regulating the first column sleeve 4 and the second column sleeve 5 lengthwise position simultaneously, described link gear is chain-drive mechanism, chaindriven average ratios is accurate, transmission power is big, described chain-drive mechanism includes driving tooth 10, transmission band 12 and driven tooth 11, described driving tooth 10 is circumferentially distributed on two movable blocks, described transmission is provided with, with 12, the driven tooth 11 matched with driving tooth 10, described transmission with 12 successively around the outside being located at the first movable block 8 and the second movable block 9, and described transmission band 12 joins end to end, said two movable block is linked by transmission band 12, when rotating the first movable block 8, driving tooth 10 on first movable block 8 and transmission are engaged with the driven tooth 11 on 12, transmission band 12 is promoted to move, transmission is engaged with the driving tooth 10 on the second movable block 9 with the driven tooth 11 on the opposite side of 12, the second movable block 9 is promoted to rotate, without driven tooth 11 and driving tooth 10, transmission drives movable block to be likely to the phenomenon producing to skid with 12 by self friction power, make two movable blocks cannot pass through transmission band 12 to link.

Described transmission band 12 is made up of gum elastic, gum elastic has good elasticity, frictional force is also big simultaneously, in time being set in two movable blocks, due to the restoring force of self, add transmission with the pressure between 12 and movable block, thus considerably increasing transmission with the frictional force between 12 and movable block, make frictional force more than transmission with 12 self gravity, make transmission band 12 not come off.

When cement mortar plain bumper works, first Membrane cover is lifted, cement mortar examination film is put on platform dish 13, the height trying film according to cement mortar pulls transmission band 12, transmission is rotated with the movable block in 12, die sleeve is elevated to and tries, with cement mortar, the height that film is corresponding, the upper surface making cement mortar examination film is inconsistent with the lower surface of Membrane cover, then Membrane cover is put down, rotate elevator 2, by lifting clamping bar 1, the clamp pin on Membrane cover is conflicted on clamping bar 1, rotating clip hook, it is made to be stuck on clamp pin, start motor, drive cam rotation, rotation along with cam, the continuous jack-up supporting roller of cam, when cam forwards certain position to, its Step of radius, so that platform dish 13 falls from certain altitude, plush copper contacts backstage dish 13 and is braked with retainer, cause that the examination film of the cement mortar on platform dish 13 shakes.

The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model. It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
