Abstract
The utility model belongs to the field of surveying and mapping, and particularly relates to an inclinometer tube opening seal protecting device. The utility model aims at overcoming the limitation and the high cost of the prior art for inclinometer tube opening protection and provides a technical scheme with the advantages of low cost, high safety coefficient and excellent seal performance. The device comprises a top cover, a bottom cover, an elastic column and a bolt, wherein the elastic column is arranged between the top cover and the bottom cover; threaded holes matched with the bolt are formed in the centers of both the top cover and the bottom cover; the bolt penetrates through the two threaded holes from top to bottom or from bottom to top, so that the top cover, the elastic column and the bottom cover are sequentially mounted in a sheathing manner; and a limiting block is arranged on the edge of the bottom cover. During the use, the bolt is tightened to enable the elastic column to produce side expansion and achieve the effect of sealing a tube opening. The device has the advantages of excellent tightness, high safety coefficient, low cost and simplicity in operation.
Description
Technical field
The utility model belongs to survey field, is specifically related to a kind of inclinometer tube orifice seal protecting device.
Background technology
The deep horizontal displacement observation mainly is to cooperate inclinometer pipe to finish by gradient-meter.Inclinometer pipe is embedded in the soil body by boring, and perhaps colligation is on the building enclosure steel reinforcement cage.After inclinometer pipe arranges, must carry out seal protection to the aperture, prevent that foreign matter from falling in the hole, cause inclinometer pipe to stop up, hinder the observation of deep horizontal displacement.
General mouth of pipe safety method has: inclinometer tube orifice exposure ground (or plane of structure), with supporting inclinometer pipe lid the aperture is covered, and this kind method is easier to destroyed at the construction field (site); After perhaps the mouth of pipe being lower than ground, make inspection shaft, protect, the method complicated operation, expense is higher, and the method is not suitable for being embedded in the seal protection of the inclinometer tube orifice in the building enclosure.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part; a kind of inclinometer tube orifice seal protecting device is provided; this device is set with top cover, elastic cylinder and bottom successively by bolt; in use bolt tightening is made elastic cylinder produce lateral expansion, so that inclinometer pipe and extraneous sealing.
The utility model purpose realizes being finished by following technical scheme:
A kind of inclinometer tube orifice seal protecting device, the ferrule that is used for inclinometer pipe, it is characterized in that described ferrule fender guard comprises top cover, bottom, the elastic cylinder between described top cover and bottom and bolt, described top cover and bottom center offer respectively the screw that matches with described bolt, and described bolt passes described two screws from top to bottom or from bottom to top and is set with successively top cover, elastic cylinder and bottom; Wherein said bottom edge is provided with limiting stopper.
Described top cover external diameter is greater than described inclinometer pipe external diameter.
Described elastic cylinder body diameter is not more than described inclinometer pipe internal diameter.
Offer pin-and-hole on the described bolt tail sidewall, be inserted with backing pin in the described pin-and-hole.
When described bolt inserts the described screw that is opened in bottom and top cover center from bottom to top, expose header field at described bolt and be combined with nut.
Vertical guide groove on described limiting stopper and the described inclinometer pipe inwall is complementary.
The utility model has the advantages that, good seal performance, easy and simple to handle, cost is low, is difficult for destroyed.
Description of drawings
Fig. 1 is that the utility model is installed in the structural representation on the inclinometer pipe;
Fig. 2 is the utility model front elevation;
Fig. 3 is the utility model cap structure schematic diagram;
Fig. 4 is spanner structure schematic diagram of the present utility model;
Fig. 5 is the structural representation of embodiment 2 of the present utility model.
The specific embodiment
Feature of the present utility model and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that the understanding of technical personnel of the same trade:
Such as Fig. 1-5, mark 1-11 is respectively among the figure: inclinometer tube orifice seal protecting device 1, inclinometer pipe 2, top cover 3, elastic cylinder 4, projection 5, spring cotter 6, bottom 7, socket bolt 8, spanner 9, bolt 10, nut 11.
Embodiment 1: as shown in Figure 1, 2, 3; the present embodiment relates to a kind of inclinometer tube orifice seal protecting device; this device is comprised of top cover 3, bottom 7, elastic cylinder 4 and socket bolt 8; described elastic cylinder 4 is between top cover 3 and bottom 7; offer a circular hole in top cover 3 centers; and offer a screw that matches with socket bolt 8 in the center of bottom 7; socket bolt 8 is passed down through the screw of elastic cylinder 4 rear access bottoms 7 from the circular hole of top cover 3, top cover 3, elastic cylinder 4 and bottom 7 suits are integrated.Wherein the afterbody at socket bolt 8 offers a pin-and-hole, and inserts spring cotter 6, plays barrier effect, falls in the inclinometer pipe 2 to prevent bottom 7 and hollow circular cylinder 4; Two groups of projections 5 that are mutually 90 ° of directions are set in the marginal portion of bottom 7, and the vertical guide groove on described projection 5 and inclinometer pipe 2 inwalls is complementary, and provides counter-force when socket bolt 8 rotation, plays position-limiting action, prevents that bottom 7 from rotating; Described elastic cylinder 4 is made by regenerated plastics and is ducted body.
Shown in Fig. 1,4, in use, inclinometer tube orifice seal protecting device 1 is put into inclinometer pipe 2, this moment, inclinometer tube orifice seal protecting device 1 belonged to free-running fit with the inwall of inclinometer pipe 2; Pull socket bolt 8 with spanner 9, make elastic cylinder 4 produce lateral expansion, the external diameter of elastic cylinder 4 is greater than the internal diameter of inclinometer pipe 2, with inclinometer pipe 2 and extraneous sealing at this moment.When need take out this device, use spanner 9 loosening socket bolts 8, elastic cylinder 4 is restored, with this device from inclinometer pipe 2 interior taking-ups.
Embodiment 2: as shown in Figure 5; the present embodiment relates to a kind of inclinometer tube orifice seal protecting device; bolt 10 in this device inserts the screw that is arranged on bottom 7 and the top cover 3 from bottom to top; bottom 7, elastic cylinder 4 and top cover 3 suits are fastened as a whole; simultaneously nut 11 is screwed on the bolt 10, with the effect that reaches the location and tighten.Identical among all the other structures of installing in the present embodiment and the embodiment 1 be not therefore repeat them here.
In use, inclinometer tube orifice seal protecting device 1 is put into inclinometer pipe 2, this moment, inclinometer tube orifice seal protecting device 1 belonged to free-running fit with the inwall of inclinometer pipe 2; Nut 11 is tightened so that elastic cylinder 4 produces lateral expansion by instrument, the external diameter of elastic cylinder 4 is greater than the internal diameter of inclinometer pipe 2, with inclinometer pipe 2 and extraneous sealing at this moment.When need take out this device, unclamp nut 11 and get final product, elastic cylinder 4 is restored, with this device from inclinometer pipe 2 interior taking-ups.
The utility model rationally utilizes the pressurized of regenerated plastics to produce the characteristic of deformation, can inclinometer pipe 2 be sealed with extraneous actv., and apparatus structure is simple, easy for installation, is easy to on-the-spot the use.
