The specific embodiment
Be elaborated below in conjunction with the specific embodiment of accompanying drawing to the utility model; Should be understood that; The specific embodiment described herein only is used for explanation and explains the utility model, and the protection domain of the utility model is not limited to the following specific embodiment.
In following explanation; Be clear some related nouns of locality of technical scheme of describing the utility model; All be normally to use the orientation to define according to supportting frock clamp (being designated hereinafter simply as " interior support frock clamp ") in the concrete pump body frame shown in Figure 2, particularly, Fig. 2 looks sketch map for the master of support frock clamp in the utility model; The side that the support frock clamp shows in Fig. 2 then is a leading flank; The side relative with leading flank is trailing flank, and correspondingly, the side of the left and right sides is the left and right side among Fig. 2.
Referring to Fig. 2 and shown in Figure 3; The interior support frock clamp of the utility model comprises clamp body 11; The outer surface of this clamp body 11 is provided with support detent mechanism at least one; In said the support detent mechanism comprise two ends have wedge surface driven voussoir 3 and be used for the wedge surface corresponding matching of said driven voussoir with the two ends of supporting and drive this driven voussoir voussoir 6 initiatively; Slides respectively and is provided with that also be connected in separately can be along on the actuator of vertical reciprocating correspondence of said driven voussoir 3 in said two ends initiatively voussoir 6; The initiatively initiatively wedge slides setting and be connected in can be along on the vertical reciprocating said actuator of said driven voussoir 3 of the end in the voussoir 6 of perhaps said two ends, other end active voussoir fixedly installs.
In above-mentioned comparatively abstract basic technical scheme; Although it is because irrelevant and not mentioned with the inventive point of the utility model; But to those skilled in the art apparently; Generally can be provided with the positioning pressuring plate 4 that is used for the inwall roof pressure of pump truck underframe casing 1 on the said driven voussoir 3, in fact the end face of driven voussoir also can be used as location roof pressure face under the plain mode.
At clamp body 11 is under the form of rectangular shape, preferably, said interior support detent mechanism is installed on the end face of this clamp body 11 and the vertical side (the for example leading flank among Fig. 2).So-called vertically side is leading flank or trailing flank promptly along the side of clamp body 11 longitudinal extensions in Fig. 2.Generally speaking, for support frock clamp in said, be provided with that the support detent mechanism just can play good positioning supports effect in two, certain, can change according to different situations.
In above-mentioned basic embodiment; It may occur to persons skilled in the art that the above-mentioned reciprocating actuator of multiple realization; Particularly, for example in Fig. 2 and Fig. 3, said actuator can be screw rod 9; This screw rod 9 be fixed in spiro rod support 10 threaded engagement on the clamp body 11, and an end is connected on the said active voussoir 6 that corresponding slip is provided with.Rotary screw 9 for ease, and the other end of screw rod 9 is provided with handle 8.Shown in Figure 2 is lower as the form cost of actuator with screw rod, and in addition, some known devices also can be realized reciprocating function, for example electric expansion bar etc.
Preferably, be under the situation of rectangular shape at above-mentioned clamp body, the end face of clamp body 11 and vertical side are provided with the wedge slides groove 5 of the said active voussoir 6 that is used for the guided slidable setting.Certainly, initiatively the structure of voussoir 6 slip settings is more, and what adopt usually is structures such as chute, guide rail.
As a kind of preferred form, in Fig. 2 and Fig. 3, every end wedge surface of driven voussoir 3 also is combined with secondary initiatively voussoir 7, and this pair active voussoir 7 is mainly used in and makes driven voussoir 3 be pushed more reposefully.Secondary active voussoir 7 is connected in initiatively voussoir 6, and certainly, this pair initiatively voussoir 7 can form as one with active voussoir 6.Preferably, have opening between secondary initiatively voussoir 7 and the active voussoir 6, be provided with the guider 2 that is used to guide driven voussoir 3 roof pressures motion that is fixed in clamp body 11 in this opening.This guider 2 is mainly used in and prevents that driven voussoir 3 from shift phenomenon occurring in the roof pressure motion, thereby makes the interior support of roof pressure better effects if, and structure is diversified certainly.Particularly, as shown in Figure 3, this guider 2 comprises the guiding bearing pin that is fixed on the clamp body 11, and this guiding bearing pin is inserted in the bullport on the said driven voussoir 3.
In addition, initiatively voussoir 6 is varied with the connected mode of screw rod 9, and under above-mentioned optimal way, said active voussoir 6 is provided with dead eye, is provided with bearing 12 in this dead eye, and said screw rod 9 passes this bearing 12 and fastening through nut.Preferably, said bearing 12 is a deep groove ball bearing.Screw rod one end makes that through deep groove ball bearing initiatively voussoir better is connected with screw rod.
The following operating process of simply describing support frock clamp in the utility model with reference to Fig. 2 and preferred implementation shown in Figure 3.
The support frock clamp is inserted in the pump truck underframe casing 1 and carries out the positioning and clamping top of corresponding hold-down mechanism pressure holding pump truck underframe casing 1 (for example through) at first will being somebody's turn to do; Turning handle 8 then; Handle 8 drives that initiatively voussoirs 6 are moving, outwards release thereby drive driven voussoir 3, with positioning pressuring plate 4 roof pressures in pump truck underframe casing; Thereby the physical dimension and the welding deformation of control pump body frame casing 1 make the moulding of pump truck underframe casing can reach requirement.Completion back backward rotation handle 8, handle 8 drives active voussoir 6 and moves backward, and driven voussoir and positioning pressuring plate 4 unclamp pump truck underframe cabinet wall, and dismantle other securing member, just can this frock clamp be withdrawed from from positioning and clamping.
Compare with the interior support frock clamp of preceding text prior art; The major technique of support frock clamp is characterised in that in the concrete mixer of the above-mentioned specific embodiment of the utility model: quantity of the driven voussoir of support detent mechanism can be one in each; Quantity reduces, and screw rod directly is connected (for example connecting through bearing) with active voussoir 6, and therefore initiatively the return of voussoir changes direct return into; More simple and reliable, precision is higher.
Can be found out that by last description the concrete advantage of the interior support frock clamp of the utility model is: support frock clamp structure is simpler in this, uses more safe and reliable, and quality gentlier, volume is littler; Simultaneously, the interior support frock clamp of the utility model has reduced the quantity of driven voussoir, and positioning accuracy is higher.In addition, support frock clamp has been realized the initiatively direct driving return of voussoir in this, is difficult for breaking down.
More than combine accompanying drawing to describe the preferred implementation of the utility model in detail; But; The utility model is not limited to the detail in the above-mentioned embodiment; In the technical conceive scope of the utility model, can carry out multiple simple variant to the technical scheme of the utility model, these simple variant all belong to the protection domain of the utility model.For example, can actuator can also be the tooth bar by gear drive.
Need to prove that in addition each the concrete technical characterictic described in the above-mentioned specific embodiment under reconcilable situation, can make up through any suitable manner.For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible compound modes.
In addition, also can carry out combination in any between the various embodiment of the utility model, as long as its thought without prejudice to the utility model, it should be regarded as content disclosed in the utility model equally.
