Abstract
The invention relates to a clamp and in particular relates to a flue hoisting clamp. The flue hoisting clamp comprises an extension pipe, a bracket plate connected at the bottom of the extension pipe and a flue frame connected at the top part of the extension pipe, wherein the flue frame is a square hollow straight tube which has a closed upper end and is larger than a flue, and a hook is arranged on the top surface of the outside of the straight tube; the extension pipe is composed of mutually-nested straight pipes, the length of the extension pipe in an extension state is equal to the length of the flue, the upper end of the straight pipe is arranged on the top surface of the inside of the flue frame, and an air bag is arranged between the straight tube and the extension pipe; the bracket plate is composed of two straight plates of which one ends are intersected, the intersected point of the straight plates is arranged at the bottom of the extension pipe by a locating pin, one end of the straight plate is provided with a baffle plate perpendicular to the upper end surface of the straight plate, and the lower end surface of the straight plate is provided with a spring for connecting the two straight plates. The flue hoisting clamp has the beneficial effects that when the flue is hoisted, the stressed area of the clamp and the flue wall is increased, and the flue outlet is prevented from collision.
Description
Technical field
The present invention relates to a kind of fixture, be specifically related to a kind of flue stone tongs.
Background technology
Flue just refers to the piping articles for the flue gas or sanitary accomodation foul smell getting rid of kitchen cooking activity generation, it is house kitchen, the chief component of sanitary accomodation common exhaust duct system, flue is be prefabricated into sulphate aluminium cement inner clip alkali-resistant glass fibre screen cloth or Portland cement inner clip wire net and other reinforcing material to form mostly, when flue is installed, traditional method pinions flue top with stay cord, then lift, but Problems existing is: walling of flue is thinner, direct stay cord is tied up, the area of thrust surface acted on walling of flue are little, floss hole is easily made to damage, in hoisting process, if floss hole is collided, be also easy to damage, thus cause flue junction to leak gas.
Summary of the invention
The object of the present invention is to provide a kind of increase and walling of flue area of thrust surface, prevent floss hole by the flue stone tongs collided.
To achieve these goals, the application proposes a kind of flue stone tongs, comprises telescopic pipe, is connected to the supporting plate bottom telescopic pipe and is connected to the flue frame at telescopic pipe top; Described flue frame is the square hollow straight tube of the upper end closed being greater than flue, and described straight tube exterior top surface is provided with hook; Described telescopic pipe is made up of mutually nested straight tube, and the length under telescopic tube state equals the length of flue, and described straight tube upper end is arranged in flue frame inside top surface, is provided with air bag between described straight tube and telescopic pipe; Two blocks of straight plates that described supporting plate is intersected by one end form, and the joining of described straight plate is arranged on bottom telescopic pipe by locating dowel pin, and straight plate one end is provided with the block perpendicular to straight plate upper surface, and straight plate lower surface is provided with the spring of the straight plate of connection two.
Compared with prior art, the present invention has following advantages: when floss hole is collided, and described straight tube has protective effect to floss hole, and described air bag and floss hole are fitted, and increase walling of flue area of thrust surface, also reduce the impulsive force to floss hole; Flue lower end holds up by described straight plate, more firm when flue is lifted, and there will not be landing.
As preferred scheme, in described little straight tube, there is less straight tube, by arranging more straight tube, the length of telescopic pipe can be shortened, reduce the space shared by fixture, convenient transport and use.
As preferred scheme, described straight plate upper surface is provided with elastic rubber fitting, makes straight plate while picking-up flue lower end, reduces the application force of straight plate to lower end floss hole.
As preferred scheme, described hook is arranged on the center of straight tube exterior top surface, makes hook and supporting plate is stressed is on same vertical curve, does not cause the extruding to walling of flue.
Accompanying drawing explanation
Fig. 1 is the cutaway view of stone tongs of the present invention.
Fig. 2 is the cutaway view that stone tongs of the present invention is connected with flue.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
A kind of flue stone tongs as shown in Figure 1, comprises hook 1, flue frame 2, air bag 3, telescopic pipe 4, locating dowel pin 5, straight plate 6, elastic rubber fitting 7, block 8, spring 9.
As shown in Figure 1, hook 1 is arranged at flue frame 2 top, and flue frame 2 inside is provided with air bag 3, telescopic pipe 4 is made up of large straight tube and little straight tube, little straight tube is contained in large straight tube, and telescopic pipe 4 is arranged on flue frame 2 inner tip, and the length under the most long status of telescopic pipe 4 equals the length of flue; The straight plate 6 intersected is arranged on bottom the little straight tube of telescopic pipe 4 lower end by locating dowel pin 5, and straight plate 6 is provided with elastic rubber fitting 7, and straight plate 6 one end is provided with the block 8 perpendicular to straight plate 6 upper surface, and straight plate 6 lower surface is provided with the spring 9 connecting straight plate 6.
As shown in Figure 2, when flue 10 lifts, extract locating dowel pin 5, get lower straight-plate 6, telescopic pipe 4 is made to be in most long status, put into from flue 10 upper port, until air bag in flue frame 2 and flue 10 upper-end contact, then straight plate 6 fixes the bottom with telescopic pipe 4 by locating dowel pin 5, now spring 9 is in compressive state, straight plate 6 is made to be in elongation state, elastic rubber fitting 7 now on straight plate 6 and flue 10 times end in contact, then inflate in air bag 3, make air bag 3 together with the close contact of flue 10 upper end, hook 1 is pinioned with stay cord, can lift, in hoisting process, because air bag 3 material is softer, large with the contact surface of flue 10, damage can not be caused to flue 10 because of pressure is excessive, if flue 10 is collided, flue frame 2 can play the effect of protection flue 10, due to the buffer action of air bag 3, the impulsive force of the upper port to flue 10 can be reduced, elastic rubber fitting 7 contacts with the lower port of flue 10, reduces straight plate 6 pairs of flue 10 lower port application forces, prevents flue 10 lower port from being damaged by pressure, after being lifted into the position needing to install, spring 9 is shunk, straight plate 6 is folded, extract locating dowel pin 5, get lower straight-plate 6, then flue 10 lower end is completed correct installation, release a part of gas in air bag 3, now easily can take off stone tongs, repeat aforesaid operations, can lift next section of flue.
The foregoing is only the detailed description of present pre-ferred embodiments, be not used for limiting the present invention, all embodiments complying with the similar change that creation spirit of the present invention is done, all should be contained among the present invention.
