Abstract

The utility model relates to a building inclined monitoring instrument, which comprises a balancing ring, a fixing ring, a pointing pipe, a hollow frustum cone, a sleeve pipe, a warning ring, a warning ring seat, a battery, and an equal difference radius concentric circle mark. The utility model is characterized in that an infrared laser head is arranged at the center of the bottom part of the hollow frustum cone; the pointing pipe is connected with the balancing ring in a supporting way through a connecting knife, and the balancing ring is connected with the fixing ring in a supporting way through the connecting knife; more than four uniformly distributed hollow conical holes are arranged on an identical cross section at the upper part of the hollow frustum cone. Compared with the prior art, the utility model has the advantages that the pointing accuracy and the sensitivity are high, the stability is good, and the operation is convenient.

Description

The building inclination monitor

The utility model relates to a kind of instrument that building inclination is monitored.

Chinese patent 91228634.2 has proposed a kind of can directly the monitoring and the building inclination monitor that can give the alarm the building inclination degree, has simple to operate, practical advantage.But in use, find that still there is the problem of following three aspects in this instrument: 1, this instrument is to aim at the concentric circles sign that the crosshair of the center pit at its sight tube top and lower end projects on the measured object dignity by naked eyes to monitor.Sighting distance is shorter owing to direct pointing, and only is applicable on the top layer face that is placed on monitored object and monitors.As be used for directly monitoring tens meters to tens meters high buildingss, just can't see the sign center clearly, it is low to sight precision.2, between its sight tube and the gimbal, be connected with coupling shaft between gimbal and the set collar, surface of contact is big, and gimbal sensitivity is not high.3, its open circles frustum swing rear stability is poor.

The purpose of this utility model is the weak point at above-mentioned building inclination monitor, proposes a kind of structurally improved building inclination monitor in addition, sights precision, sensitivity and stability with further raising instrument.

The utility model is realized in the following way: this building inclination monitor comprises gimbal, set collar, sight tube, open circles frustum, sleeve pipe, warning ring, warning ring seat, electric battery, the equal difference radius concentric circles sign that former building inclination monitor is provided with, and is improved from following three aspects: 1, the bottom centre in the open circles frustum is provided with the infrared laser head; 2, adopt between sight tube and the gimbal and between gimbal and the set collar and is connected the connection of cutter support; 3, on the top of open circles frustum in opening open circles taper hole uniform more than four on the same cross section.When using this monitor that buildings is monitored, support about 1.3 meters high of instrument with tripod 4, the tripod point is placed on the top layer of buildings, or instrument is suspended on the top of buildings, makes instrument directly to the ground floor of buildings.Opening power, infrared laser are got red point immediately downwards, then the top layer of buildings or on its ground floor mobile concentric circles sign the red point of center and laser is overlapped, fix sign.When the buildings run-off the straight, the red point of laser is departed from the center of circle of equal difference radius concentric circles sign, and the distance of reading the red point of laser and the concentric circles center of circle just can converse the degree of tilt of buildings.When building inclination when the frustum of a cone being run into report to the police ring, circuit is connected, electric bell sends the building inclination alarm.Because the lower end of the utility model sight tube is connected to the open circles frustum, under the effect of its underpart own wt and gimbal, the center line of crossing sight tube, open circles frustum, laser head is a vertical line, thereby the line of the infrared laser point that sends under the mind-set therein of laser head is a vertical line.The utility model replaces former building inclination monitor with the naked eye to aim at the collimation line of crosshair with the infrared laser vertical line, thereby can improve accuracy of observation and prolong sighting distance.Simultaneously, with gimbal and sight tube and with set collar between be connected by connecting with coupling shaft to change into and connect the sensitivity that has improved gimbal with connecting the cutter support.The uniform open circles taper hole of offering on the open circles frustum then can play the effect of stablizing the open circles frustum by air damping.

This shows that the utility model compared with prior art has precision sighted and highly sensitive, good stability, easy to operate advantage.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.

With reference to Fig. 1, Fig. 2, this building inclination monitor comprises the critical piece of former building monitor: sight tube 10, gimbal 2, set collar 3, sleeve pipe 7, open circles frustum 11, report to the police ring 14, warning ring seat 15, electric battery 18, electric bell 19, equal difference radius concentric circles sign 16, connecting

screw

8,17 is connected with the ring 14 of reporting to the police, electric battery 18, electric bell 19 by power lead 9.This monitor is loaded onto the laser head 13 that can send infrared laser point downwards at the center, lower end of open circles frustum 11, is connected with power supply by power lead.Adopt respectively between sight tube 10 and the gimbal 2 and between gimbal 2 and the set collar 3 and is connected

cutter

5,6 connections.With reference to Fig. 1, Fig. 3, Fig. 4, Fig. 5, connect cutter 5 and be fixed on the gimbal 2, the center of crossing in sight tube 10 tops has the two hole 10-1 that are mutually 180 degree angles, connects cutter 5 and penetrates in the 10-1 of hole, and the knife edge support that makes progress connects sight tube 10.Connect cutter 6 and be fixed on the set collar 3, the center of crossing in gimbal 2 tops has the two hole 2-1 that are mutually 180 degree angles, connects cutter 6 and penetrates in the 2-1 of hole, and the knife edge support that makes progress connects gimbal 2.On the top of open circles frustum 11, on same cross section, have at least 4 uniform open circles taper holes 12.Upper end at sight tube 10 preferably adds pipe cap 1, mutually to be threaded.Pipe cap 1 can play the effect of decorating and protecting sight tube.
