Abstract

The utility model discloses an oil pipe clamp. The oil pipe clamp comprises a pipe clamp cover plates, a pipe clamp base and a fastening screw, wherein the pipe clamp cover plate and the pipe clamp base are adjacent to each other in the vertical direction, one end of the pipe clamp cover plate and one end of the pipe clamp base are fixedly connected through the fastening screw, the side face, adjacent to the pipe clamp base, of the pipe clamp cover plate and the side face, adjacent to the pipe clamp cover plate, of the pipe clamp base are respectively provide with at least one pair of arc-shaped concave portions matched with oil pipes in diameter, and the other end of the pipe clamp cover plate and the other end of the pipe clamp base are hinged through a hinge bolt and nuts. The oil pips clamp is simple in structure and convenient to manufacture, the pipe clamp cover plate is kept connected with the pipe clamp base all the time, the oil pipes can be taken out after the pipe clamp cover plate is opened in the detachment process, labor intensity of an operator is lowered, assembly efficiency is improved, the problem that the pipe clamp cover plate is not matched with the pipe clamp base can not occur, and the hydraulic oil pipes are rapid and convenient to fix, stable and reliable.

Description

Oil pipe clamp

Technical field

The utility model relates to a kind of oil pipe fixing device, and especially a kind of pipe clamp for the hydraulic oil pipe that is fixedly clamped, belongs to pipe fittings technical field.

Background technique

The hydraulic oil pipe pipe clamp of engineering machinery is for fixed hydraulic oil pipe, and because the load change of engineering machinery is large, operating mode is severe, hydraulic oil pipe vibration is frequent, particularly important with the reliable fixed hydraulic oil pipe of pipe clamp.Engineering machinery, in the time changing accessory or maintenance, often need to be dismantled pipe clamp.The pipe clamp seat of existing hydraulic oil pipe pipe clamp is generally fixed on the associated components of engineering machinery, after pipe clamp detachable cover plate with pipe clamp seat in separated state, be very easy to occur the phenomenon that pipe clamp cover plate is lost or the pipe clamp cover plate of different model is obscured.As at will looked for one to fix hydraulic oil pipe with the unmatched pipe clamp cover plate of pipe clamp seat, will cause hydraulic oil pipe fixing unstable, while causing engineering machinery to use hydraulic oil pipe vibration frequent, until there is the loosening and fault of leakage of oil of oil connection; Continue to find the pipe clamp cover plate mating and reduced operator's efficiency.

Model utility content

The purpose of this utility model be to provide a kind of simple in structure, convenient to operation, lock reliable and stable oil pipe clamp.

The utility model is achieved by the following technical programs:

A kind of oil pipe clamp, comprise neighbouring pipe clamp cover plate, pipe clamp seat and be fixedly connected with pipe clamp cover plate one end and the fastening screw trip bolt of pipe clamp seat one end, described pipe clamp cover plate is respectively equipped with in pipe clamp seat adjacent side the arc indent that at least one pair of mates with tubing diameter; The pipe clamp cover plate the other end and the pipe clamp seat the other end are hinged by hinge bolt, nut.

The purpose of this utility model can also further realize by following technical measures.

Aforesaid oil pipe clamp, while wherein clamping oil pipe, leaves gap a between pipe clamp cover plate and pipe clamp seat adjacent side, described gap a=2.0 mm～3.5mm.

Aforesaid oil pipe clamp, the diameter of wherein said hinge bolt is greater than fastening screw trip bolt diameter.

The utility model is simple in structure, easy to make, pipe clamp cover plate remains and being connected of pipe clamp seat, when dismounting, first unload fastening screw trip bolt, overturn again after pipe clamp cover plate and just can take out oil pipe, in the labor intensity that reduces operator, also improved efficiency of assembling, pipe clamp cover plate and the unmatched problem of pipe clamp seat can not occur, hydraulic oil pipe is fixing efficient and convenient, reliable and stable.

Advantage and disadvantage of the present utility model, by for illustration and explanation the non-limitative illustration by preferred embodiment below, these embodiments, only provide as an example with reference to accompanying drawing.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model locking state;

Fig. 2 is the structural representation of the utility model open mode;

Fig. 3 is the left view of Fig. 1.

Embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail.

As shown in FIG. 1 to 3, the present embodiment comprises neighbouring pipe clamp cover plate 1, pipe clamp seat 2 and connects the fastening screw trip bolt 3 of pipe clamp cover plate 1 right-hand member and pipe clamp seat 2 right-hand members, pipe clamp cover plate 1 and the arc indent 5 that is respectively equipped with at least one pair of in pipe clamp seat 2 adjacent side and mates with oil pipe 4 diameters, the present embodiment is provided with two pairs of arc indents 5 altogether, can be used for fixing two oil pipes 4.As required, the quantity of arc indent 5 can be more than 3 or 3.The degree of depth A of pipe clamp cover plate arc indent 51 is less than the radius R of oil pipe 4, the depth B of pipe clamp seat arc indent 52 equals the radius R of oil pipe 4, therefore, pipe clamp cover plate 1 and pipe clamp seat 2 are clamped after oil pipe 4, between the adjacent side of pipe clamp cover plate 1 and pipe clamp seat 2, leave gap a, the gap a=3.0mm of the present embodiment, guarantee that pipe clamp cover plate 1 and pipe clamp seat 2 clamp oil pipe 4, also can adopt the depth B of pipe clamp seat arc indent 52 to be less than the radius R of oil pipe 4, the degree of depth A of pipe clamp cover plate arc indent 51 equals the structure of oil pipe 4 radius Rs.

Pipe clamp cover plate 1 left end of the present embodiment extends vertical end 11 downwards, pipe clamp seat 2 left ends are provided with the jaw corresponding with vertical end 11 21, vertical end 11 is inserted in jaw 21 by hinge bolt 6, nut 7 hinged, the utility model also can adopt pipe clamp cover plate 1 and pipe clamp seat 2 be fixedly connected with end at left end, articulated position the structure at right-hand member; Or pipe clamp cover plate 1 right-hand member extends vertical end 11 downwards, and jaw 21 is arranged on the structure of pipe clamp cover plate 1 right-hand member.In a word, the rounded end position of pipe clamp cover plate 1 and pipe clamp seat 2, vertical end and corresponding jaw position can not be subject to the restriction of the present embodiment.

In the process of clamping oil pipe 4, hinge bolt 6 is subject to shearing force effect, and the permitting stress of identical material is much smaller than allowable tensile stress, cut off for fear of hinge bolt 6, the diameter of hinge bolt 6 is than the large specification of fastening screw trip bolt 3 diameters, the fastening screw trip bolt 3 of the present embodiment is Φ 12mm, and hinge bolt 6 is Φ 14mm.

In addition to the implementation, the utility model can also have other mode of executions, and all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
