Abstract
The utility model relates to a transmission enlarging type value indicating device for the cable inlet bracket or the shell of the existing alloy aluminium section verticality detecting rule. The transmission enlarging type value indicating device is composed of a transmission enlarging mechanism, a gravity hammer, a value indicating device, a hair spring and damping. The transmission enlarging type value indicating device is characterized in that via the transmission enlarging mechanism is driven to operate via the function on the gravity hammer by the earth gravity, and the reading is displayed by the indicator; moreover, under the function of the damping and the hair spring, the transmission enlarging type value indicating device is caused to realize the goal of rapid stop of the gravity hammer, the time saving and improving the checking work quality. The utility model has the advantages of high precision, labor saving.
Description
The utility model relates to a kind of building installation engineering verticality testing tool field.
Known to the present utility model people:
1, played that the testing tool to 1～2 meter kinds of construction verticality is to use wooden cable inlet bracket in " unified standard for quality inspection and assessment of building costructional erection works " of execution on September 1st, 1989, make benchmark with messenger wire, shortcoming is: (1) carries inconvenience, has 2 meters long; (2) messenger wire comes to a complete stop slowly, meets little wind slightly and rocks especially incessantly; (3) low precision, messenger wire are pressed close to batten slightly can be dull, can produce parallax again if leave a bit, and this instrument is again each family's self-control, and material and cross dimensions respectively have selection, and these all can bring influence to testing result.
2, the present utility model people once manufactured experimently and promoted a kind of verticality detection ruler, be to select two 1000 * 50 * 25(millimeters for use) empty stomach alloy aluminum section bar, link by special hinge, folding back length is 1 meter, section is 50 * 50(millimeter), be provided with the pendulum that 3 * 500 millimeters steel wires of φ are done in the section bar empty stomach, drive pointer and show reading by the pendulum action.The measured value mechanism of this detection ruler though solved some shortcoming of cable inlet bracket, still has weak point: the one, and pendulum time of coming to a complete stop is short not enough; The 2nd, hold chi and still must keep certain vertical requirement.
The purpose of this utility model be for aluminium section bar detection ruler housing provide a kind of come to a complete stop fast, precision is high, hold the transmission amplifying type indicating value device that the chi bar needn't be enough vertical.
The utility model is realized as follows: this transmission amplifying type indicating value device is mainly by bearing pin, the garden dish, clamping plate, gravity drop hammer, pointer, scale plate, hairspring and damping are formed, described bearing pin is to coil into vertical fixing with the garden to cooperate And that the garden dish of different joints garden radius is meshed to be loaded on each position, corresponding hole of clamping plate, fastening in addition by the bolt pair then, constituted a linkage magnification system thus, when the gravity drop hammer on being installed in active garden dish is subjected to terrestrial attraction to be used as the trend vertically-acting, drive linkage magnification system, show reading by pointer, in order to realize that gravity drop hammer comes to a complete stop soon, the purpose that precision is high is provided with damping and hairspring to this device.
Further illustrate content of the present utility model below in conjunction with accompanying drawing:
Fig. 1 is a front elevation of the present utility model;
Fig. 2 is a side view of the present utility model.
Do to amplify the requirement of transmission according to this device needs, with garden dish (1,2,3) be designed to different joints garden radius, (1,2,3) respectively with bearing pin (4,5,6) the one-tenth vertical fixing cooperates And and makes their formation engagements be loaded on clamping plate (7,8) corresponding Kong Weizhong, has equidistant shoulder first bolt adjutant (7 by four, 8) fastening, constituted a linkage magnification system thus, gravity drop hammer (9) rivet clasp is on (1), both sides in (9) are provided with damping (10 respectively, 11), one end of hairspring (12) is fixed on (6), the other end is fixed on (7) (also can be fixed on (8)), (3) pointer (13 is equipped with at two ends respectively, 14) ， And are (13,14) load onto scale plate (15 below, 16).According to the rules, construction and installation kinds of construction perpendicularity deviation value is to be unit with the millimeter, therefore the frame bar of (15,16) is designed to represent 1 millimeter with 1 lattice, see easily and read in order to adapt to some weak-eyed testing staff, the frame bar size is selected 1.2 millimeters for use,, pointer radius of gyration R, garden dish joint garden radius d, d
1Their relations can be tried to achieve by following formula:
R=1.2 (2000d
1 2)/(d
2) 2000 be detection ruler blade length in the formula.
This transmission amplifying type indicating value device is installed in existing alloy aluminum section bar verticality detection ruler housing, with realize that gravity drop hammer comes to a complete stop soon, measured value precision height, holding chi needn't the vertical effect of strictness, thereby reach laborsaving, save time and improve the purpose of testing quality.
This device also can be installed in and replace messenger wire to make indicating value usefulness on the cable inlet bracket.
Claims (3)
1, a kind of transmission amplifying type indicating value device of forming by garden dish, bearing pin, clamping plate, gravity drop hammer, damping, hairspring, pointer and scale plate, it is characterized in that gravity drop hammer (9) rivet clasp is on garden dish (1), and (1) with garden dish (2) engagement, mesh with garden dish (3) again (2).
2, transmission amplifying type device according to claim 1 is characterized in that the both sides of gravity drop hammer (9) are respectively equipped with damping (10,11).
3, driven type indicating value device according to claim 1 is characterized in that an end of hairspring (12) is fixed on the bearing pin (6), and the other end is fixed on the clamping plate (7), and is respectively equipped with pointer (13,14) at the two ends of (3).
