Specific embodiment

The utility model is described in further detail in the following with reference to the drawings and specific embodiments, is not that this is practical Novel practical range limited to this.

It should be noted that in the description of the present invention, term " transverse direction ", " longitudinal direction ", "upper", "lower", " preceding ", The orientation or positional relationship of the instructions such as " rear ", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" be based on Orientation or positional relationship shown in the drawings, is merely for convenience of describing the present invention and simplifying the description, and is not instruction or dark Show that signified device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as pair The limitation of the utility model.

As shown in Figure 1-Figure 3, a kind of cement pump truck of the present embodiment is connected to seat automatic centering boring grab, including bracket 1, The bracket 1 is provided with the vertical plate 2 that can withstand connection seat inner wall and the two piece mandrils 3 arranged side by side with 2 front and back of vertical plate, the top The adjustable height of bar 3；It is provided with the pressing plate 4 being threadedly coupled with the bracket 1 above the vertical plate 2, is set above the mandril 3 It is equipped with the bolt 5 with the bracket 1 by insertion connection；Rotatable first sleeve 6 is provided with below the vertical plate 2, it is described The both ends of first sleeve 6 be provided with can simultaneous retractable thimble A8 and thimble B9, be provided with rotatable below the mandril 3 Two sleeves 7, the both ends of the second sleeve 7 be provided with can simultaneous retractable thimble C10 and thimble D11.

In use, connection seat is placed on the vertical plate 2 and the mandril 3, wherein the concave surface of the U-shaped shell of connection seat Downward, the top of the vertical plate 2 is arc-shaped, can be bonded well with the arcwall face of connection seat inner wall, to contradict connection Seat, two mandrils 3 are withstood in the plane of connection seat inner wall, and such three-point fix is played the role of to connection seat bearing, together When prevent connection seat rotation；The pressing plate 4 is installed and is inserted into the bolt 5, connection seat pressed from above rotates the first set Cylinder 6 and the second sleeve 7 make the thimble A8, the thimble B9, the thimble C10 and the thimble D11 simultaneously to overhanging Out, to make to be connected to seat about the facade centering where the axis of its U-shaped shell, the height for adjusting the mandril 3 makes to be connected to seat On half slot be bonded with the bolt 5, being at this moment connected to seat needs the planar horizontal of bore position, and tightening nut makes the pressing plate 4 Compress connection seat.

The mandril 3 need to play supporting role to connection seat, so the mandril 3 is threadedly coupled with the bracket 1, so that When being connected to seat drilling, connection seat will not sink under the pressure of drill bit.

The pressing plate 4 and the bracket 1 are separate structures, and there are two U-type grooves at the both ends of the pressing plate 4, in use, in institute Two screw rods of setting on bracket 1 are stated, the pressing plate 4 is mounted on the bracket 1 by U-type groove and screw rod fitting, then in screw rod On screw on nut and compress the pressing plate 4；Two U-type grooves of the pressing plate 4 can also be two through-holes.

To be inserted into the bracket 1 convenient for the bolt 5, the diameter of the middle section of the bolt 5 should be less than both ends and institute State the diameter of 1 mating part of bracket；Because the bolt makes cylinder, the end of the bolt 5 is provided with rectangular slab, the branch It is provided with scotch 12 on frame 1, the rotation of the bolt 5 is prevented by being bonded for rectangular slab and the scotch 12.This place Stating bolt 5 can be configured as with the bracket 1 hingedly, then tight with fastener by being pressed in the half slot of connection seat under overturning Gu.

Because the U-shaped shell of connection seat only has an axis, the first sleeve 6 is parallel with the second sleeve 7, And the axis of the first sleeve 6, the second sleeve 7 and the U-shaped shell axis vertical take-off that is connected to seat.

The both ends of the first sleeve 6 are provided with the contrary screw thread of thread, in this way, when the first sleeve rotates When, the thimble A8 being threadedly coupled with the first sleeve 6 and the thimble B9 can be made to stretch out or retract simultaneously；Described The both ends of two sleeves 7 are provided with the contrary screw thread of thread, in this way, when the second sleeve 7 rotation when, can make with it is described The thimble C10 and the thimble D11 that second sleeve 7 is threadedly coupled are stretched out or are retracted simultaneously.

The thimble A8, the thimble B9, the thimble C10 and the thimble D11 are slided with the bracket 1 respectively to be connected It connects, but is not rotatablely connected, in this way when the first sleeve 6 or the second sleeve 7 rotate, the thimble A8, the top Needle B9, the thimble C10 and the thimble D11 are not able to rotate by the blocking of the bracket 1, can only be under spiral force to overhanging It retracts out or inwardly.

The bracket 1 is provided with the holding screw M13 for preventing the first sleeve 6 from rotating and prevents the second sleeve 7 The holding screw N14 of rotation；After being connected to seat centering, the holding screw M13 and the holding screw N14 are screwed, it can be to prevent Only the first sleeve 6 or the second sleeve 7 are circled round, and cause the thimble A8, the thimble B9, the thimble C10 and institute Connection seat cannot be withstood well by stating thimble D11.

Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this The spirit and scope of utility model technical solution.
