Embodiment
Core of the present utility model provides a kind of engineering machinery angle detection system, and the installation site of scrambler is more wide in range in this detection system, the restriction of installing space is reduced, and be not subjected to the influence of reductor.
In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 2, Fig. 2 provides a kind of structural representation of embodiment engineering machinery angle detection system for the utility model.
In this embodiment, the engineering machinery angle detection system comprises pivoting support 1 and installing plate 2 thereof, scrambler 3, the detection axle 5 of scrambler 3 links to each other with special rotating transmission device 4, the gear driven rotating transmission device 4 of pivoting support 1 rotates, and the detection axle 5 that rotating transmission device 4 drives scrambler 3 again rotates.The rotating transmission device volume is less, and the suffered restriction in scrambler 3 installation sites reduces, and is fixedly mounted on the installing plate 2.
Please refer to Fig. 3, Fig. 3 is the rotating transmission device in the engineering machinery angle detection system shown in Figure 2 and the installation process synoptic diagram of scrambler, scrambler 3 can be fixing by screw and mounting blocks 7, again that mounting blocks 7 is fixing with installing plate 2, thereby realize the fixing of scrambler 3 and installing plate 2, actual operation is strong.Certainly, in theory, scrambler 3 also can be directly by screw retention on installing plate 2.
Mounting blocks 7 can be connected with installing plate 2 by vertical rod 8.Process the hole that equates with vertical rod 8 numbers on mounting blocks 7, vertical rod 8 one ends insert the hole in the mounting blocks 7, and the other end and installing plate 2 are fixing.Preferably adopted three vertical rods among the embodiment, mounting blocks 7 is a triangle, and three drift angle places are processed with three fixedly holes of vertical rod.
Please refer to Fig. 4, Fig. 4 is the structural representation of rotating transmission device in the engineering machinery angle detection system shown in Figure 2.Because the detection axle 5 of scrambler 3 is thinner usually, directly link to each other with connection gear 41, there is certain difficulty technically, in order further to improve the simplification that connection gear 41 is installed, rotating transmission device 4 can also comprise pass connection gear 41 and with its axle 42 that rotates with speed, the detection axle 5 of scrambler 3 is connected with an end of spools 42.Under this connected mode, connection gear 41 does not directly drive detection axle 5 and rotates, and during work, 1 gear driven connection gear 41 rotations are supported in revolution, and connection gear 41 drives axle 42 and rotates, and drives detection axle 5 by axle 42 again and rotates.
In engineering machinery with rotation class operation part, the normally requisite parts of pivoting support 1 and installing plate 2.Rotating transmission device 4 only comprises parts such as connection gear 41, axle 42, simple in structure, volume is less comparatively speaking, therefore, when scrambler 3 is connected by rotating transmission device 4 with the gear of pivoting support 1, be meshed as long as guarantee the gear of connection gear 41 and revolution support 1, scrambler 3 can be installed in the position that any space allows on the installing plate 2.Connection gear 41, axle 42 and scrambler 3 concrete connected mode and associated components please refer to Fig. 5, and Fig. 5 is each parts erection sequence synoptic diagram of rotating transmission device shown in Figure 4.Connection gear 41 is fixed on an end of axle 42, can install according to the order of bolt 46, packing ring 47, connection gear 41 and baffle plate 44 successively from outside to inside.The other end (gearless end) of axle 42 then is inserted in the bearing seat 43 by bearing 49, bearing 49 comprises the clutch shaft bearing 491 and second bearing 492, and bearing seat 43 is between two bearings, during installation, bearing seat 43 is fixed in the mounting hole of installing plate 2, and then fixes connection gear 41 and axle 42.
Two bearings can be fixed by following mode with bearing seat 43: a side of the clutch shaft bearing 491 of close connection gear 41 links to each other with bearing seat 43, opposite side links to each other with bearing gland 45, one side of second bearing 492 links to each other with back-up ring 48, and opposite side links to each other with bearing seat 43.
When rotating transmission device 4 is installed, can be earlier on installing plate 2 centre distance according to connection gear 41 and pivoting support 1 gear matched process mounting hole.The clutch shaft bearing 491 and second bearing 492 all are fixed in the bearing seat 43, and rotating transmission device 4 can be used as a global facility and is installed on the installing plate 2, also can be assembled in successively on the installing plate 2.At last, by bolt 9 bearing seat 43 is fixed on the installing plate 2 again, certainly, also can directly fixes by other modes such as welding, riveted joints.
Since the effect of two bearings, the rotation sensitivity of axle 42, therefore, can take the connected mode of interference fit between axle 42 and the connection gear 41, promptly compress connection gear 41 and axle 42 compression fit, can realize that equally connection gear 41 drives axle 42 and rotates, reduced cost of processing.
Scrambler 3 is fixedly mounted on installing plate 2 belows (comparatively speaking, rotating transmission device 4 is installed in the top of installing plate 2) and the corresponding position of mounting hole, mounting hole is penetrating, when using mounting blocks 7 regular coding devices, also need to be processed with corresponding through hole on the mounting blocks 7, at this moment, the detection axle 5 of scrambler 3 can be connected with the gearless end of axle 42, thereby realizes that axle 42 drives detection axle 5 and rotates.
Scrambler 3 is installed in the below of installing plate 2, installing plate 2 can protect scrambler 3 in the engineering machinery bad working environment not by clashing and breaking, do not need to increase extra protective device, the cost that reduces design and make.
Detect axle 5 and can be connected by shaft coupling, realize coaxial rotation comparatively easily with axle 42.Preferred flexible shaft coupling 6 guarantees under the prerequisite of higher transmission efficiency that not high to requirement on machining accuracy, processing cost is also lower.
The rotating transmission device 4 that more than one scrambler 3 can be installed on the installing plate 2 and match with it.The rotating transmission device 4 that the utility model provides is simple in structure, installs that this device can not increase installation difficulty more than one, also helps to detect more accurately the anglec of rotation of pivoting support.
More than engineering machinery angle detection system provided by the utility model is described in detail.Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
