Abstract

The utility model discloses a kind of derrick inclination angle indicator, including the base plate that is fixed on derrick and otic placode, two retainers are symmetrically arranged with base plate top two sides interval, are symmetrically fixed with two scale boards on base plate bottom two sides;Otic placode is passed downwardly through bearing pin and is hinged with the afterbody of pointer, and the two sides arrow of pointer is each passed through downwards a corresponding retainer, is engaged with the graduation mark of each scale board.Device of the present utility model, can indicate the inclination angle during truck-mounted drill rig derrick installation fast accurate, simplify derrick installation adjustment operation, improve derrick installation efficiency, and simple structure is economical and practical.

Description

Derrick inclination angle indicator
Technical field
The utility model belongs to technical field of petroleum machinery, is related to a kind of derrick inclination angle indicator.
Background technology
Derrick inclination angle instruction equipment is the important corollary equipment that the derrick installation of oil truck-mounted drill rig is fixed, and truck-mounted drill rig is in well Erecting needs to incline 2~3.5 ° to well head direction after rising, and derrick inclination angle is too small to cause to swim crane system and derrick interference and collision, and Derrick inclination angle is excessive, and derrick stress can be made severe, so as to affect the security performance of derrick, therefore precise control truck-mounted drill rig well Frame angle of inclination is most important to the use of truck-mounted drill rig.
Currently, when fixed truck-mounted drill rig derrick is installed, often through range estimation and micro-judgment derrick inclination angle, the tune at inclination angle Whole precision is affected larger by operating personnel's experience and qualification, if improper during work, needed to readjust derrick and is inclined Angle, this cause operative employee's labour intensity to increase, and greatly reduce operating efficiency of the derrick during mounting and adjusting.
Utility model content
The purpose of this utility model is to provide a kind of derrick inclination angle indicator, solves prior art by range estimation and experience Judge that derrick inclination angle, the Adjustment precision at inclination angle are affected larger problem by operating personnel's experience and qualification.
The technical scheme adopted by the utility model is that a kind of derrick inclination angle indicator, including the bottom being fixed on derrick Plate and otic placode, are symmetrically arranged with two retainers at base plate top two sides interval, are symmetrically fixed with two on base plate bottom two sides Scale board;Otic placode is passed downwardly through bearing pin and is hinged with the afterbody of pointer, and the two sides arrow of pointer is each passed through downwards corresponding one Retainer, is engaged with the graduation mark of each scale board.
Derrick inclination angle of the present utility model indicator, is further characterized in that:
Pointer is double pointers.
The beneficial effects of the utility model are to indicate the inclination angle during truck-mounted drill rig derrick installation fast accurate, Simplify derrick installation adjustment operation, disposably adjustment is installed in place to make derrick, improve derrick installation efficiency, simple structure is economical Practical.

Specific embodiment
With reference to the accompanying drawings and detailed description the utility model is described in detail.
With reference to Fig. 1, Fig. 2, Fig. 3, structure of the present utility model is, including the base plate 1 that is fixed on derrick 8 and otic placode 6, 1 top two sides of base plate interval is symmetrical arranged (welding) two retainers 2, symmetrically fixes (by bolt on 1 bottom two sides of base plate 7 are fixedly connected) there are two scale boards 3 (being easy to two sides calibrate);Otic placode 6 passes downwardly through the tail of bearing pin 5 and pointer 4 Portion is hinged, and pointer 4 is double pointers, and the two sides arrow of pointer 4 is each passed through downwards a corresponding retainer 2, with each scale The graduation mark of board 3 is engaged, i.e., pointer 4 downward through 1 both sides of base plate retainer 2 and indicate on the groove of scale board 3.
With reference to Fig. 4, Fig. 5, operation principle of the present utility model is,
First, when ensureing that derrick 8 is in erectility, base plate 1 and otic placode are correspondingly separately fixed at derrick 8 about 6 Side correct position, and the direction of 3 scale value of scale board increase is consistent with well head direction, now pointer 4 points to 0 ° of scale board 3 Position;
Then, during derrick telescoping, the continuous inclination angle of adjustment derrick 8, when seeing what pointer 4 was indicated on scale board 3 Angle for needed for derrick 8 during inclination angle (2~3.5 ° of the technical requirements angle that raising reaches), that is, completes raising, fixes derrick 8 i.e. Into.
