Abstract
The utility model discloses a device for collecting a rotation angle signal of a concrete jetting mechanical arm frame, which comprises a rotary encoder and a small gear, wherein a central rotating shaft of the small gear is fixed on a bearing pedestal of an arm frame installation plate; the small gear is meshed with a large gear ring for driving the arm frame to rotate; and the rotary encoder is connected with the central rotating shaft of the small gear. The device has a simple structure, is reliable in working and can realize the automatic or semi-automatic control of the arm frame spraying process without adopting a special motor with a shaft.
Description
Technical field
The utility model belongs to tunnel buttress water-bearing concreae casting equipment, particularly relates to a kind of harvester that is used for concrete sprayer tool arm frame rotary angle signal.
Background technology
Concrete sprayer is a kind of equipment that is used for tunnel buttress water-bearing concreae cast, moves by operation concrete sprayer jib and finishes the cast of concrete to an arch ancient piece of jade, round, flat and with a hole in its centre.Therefore the order of accuarcy of controlling the action of spraying machine jib directly influences casting quality.
Available coagulation soil spraying machine all is to finish cast to the tunnel buttress by operating the action of jib and shower nozzle manually.Because the operator is to the unskilled of jib operation or lack experience, will cause that the concrete springback rate is excessive, a mask is uneven, leak spray, problems such as many sprays, bring certain influence to subsequent handling, cause the unnecessary waste of concrete simultaneously.Simultaneously manually carry out continual operation for a long time, labour intensity is bigger.So can adopt the action of semi-automatic and full-automatic programmed control jib and shower nozzle to finish the spraying of an arch ancient piece of jade, round, flat and with a hole in its centre for the straight preferably tunnel of operating mode, to remedy its above-mentioned defective.
The automatic control that realizes jib and shower nozzle at first must collect the real-time status that jib rotates whole process, a series of actions when finishing automatic casting by the control jib anglec of rotation.The general structure that adopts of the real-time collection of the anglec of rotation at present is: the little axle of motor afterbody output that drives the jib rotation, the rotating speed of little axle and the rotating speed of motor are in full accord, rotary encoder is linked to each other by shaft coupling with little axle, transmit rotation relationship, finish the collection of rotation radian.But because the rotating speed of little axle is very fast, vibrations herein are bigger, disturb greatlyyer, and the little axle and the utensil of encoding are fragile, and user's maintenance cost is higher.
The utility model content
Technical problem to be solved in the utility model provides a kind of harvester that is used for concrete sprayer tool arm frame rotary angle signal of simple in structure, reliable operation, need not to dispose special tape spool motor, reach the process automatic or that the semiautomatic control jib sprays that realizes.
In order to address the above problem, the utility model has adopted following technical scheme.The harvester that is used for concrete sprayer tool arm frame rotary angle signal comprises rotary encoder, pinion wheel, the centre rotational axis of described pinion wheel is fixed on the bearing seat on the jib installing plate, pinion wheel and the bull gear engagement that drives the jib rotation, described rotary encoder is connected with the centre rotational axis of pinion wheel.
Described rotary encoder is connected with the centre rotational axis of pinion wheel by shaft coupling.
Described rotary encoder is fixed on the described bearing seat by mount pad.
Described holder is provided with the over cap of rotary encoder.
Compared with prior art, the rotating signal harvester that provides of the utility model has following effect:
1) the utility model is the principle of transfer line speed unanimity when utilizing big pinion, pinion wheel directly rotated with jib mesh with bull gear, the anglec of rotation of pinion wheel is passed to rotary encoder by centre rotational axis, draw the anglec of rotation of jib by the central control unit conversion Calculation.Therefore have signals collecting and transmit characteristic of accurate.
2) this device is installed on the jib revolution stand, the vibration that produces during concrete sprayer work is less with the pinion wheel centre rotational axis influence that is connected to scrambler, the serviceable life that helps improving scrambler and shaft coupling.
3) this mechanism need not dispose the motor of special band angular displacement axle, and is cheap, reduced user's maintenance cost.
By the field test of a period of time, prove that this covering device can accurately transmit the real-time angle of jib rotation, for automatic and semi-automatic injection provides data necessary control.
In sum, the utility model is a kind ofly can accurately gather the jib anglec of rotation and dependable performance, the concrete sprayer tool arm frame rotary angle signal harvester that maintenance cost is cheap.
Below in conjunction with drawings and Examples the utility model is described further.

Fig. 2 is a front view of the present utility model.
Fig. 3 is the sectional view of Fig. 2.
Embodiment
As shown in Figure 1 to Figure 3, the utility model comprises the mount pad 9 that changes scrambler 1, pinion wheel 5, bearing seat 8, rotary encoder, the hole that bearing seat 8 passes on the jib installing plate 11 is fixed on the installing plate 11, be placed with rolling bearing 7 in it, the rolling bearing 7 that the centre rotational axis 4 of pinion wheel 5 passes in the bearing seat 8 is connected by shaft coupling 10 with rotary encoder 1; Mount pad 9 is cylindric, and the one end is fixedlyed connected with bearing seat 8, and the other end is rotary encoder 1 fixedly, and its barrel is provided with the mounting hole 12 of shaft coupling; Mount pad 9 is provided with the over cap 2 of rotary encoder 1; The mount pad 9 of bearing seat 8 and rotary encoder is fixed on the installing plate 11 by bolt 3, pinion wheel 5 and bull gear 6 engagements that drive the jib vertical rotation.
As shown in Figure 1, 2, this device is the collection that the principle of transfer line speed unanimity when utilizing big pinion realizes the anglec of rotation.When bull gear 6 rotations, the pinion wheel 5 that drive is engaged with rotates, pinion wheel 5 rotation angle information pass to rotary encoder 1 by the centre rotational axis 4 that is connected on the pinion wheel 5, rotary encoder 1 draws the actual anglec of rotation of jib with the data that collect after the central control unit conversion Calculation, realize automatic casting control for jib crucial Data Source is provided.
