Description
Technical field
The present invention relates to small rail car assembling travel line technical field, particularly a kind of small rail car switches collision prevention device with high low speed.
Background technology
For the small rail car assembling travel line that uses chain to drag, because automated assembly line is comprised of many different stations, the beat between each station there are differences, and the distance between each station also there are differences.Improve the plant efficiency of whole automated assembly line, need to automatically select high low speed chain according to different station, when two small rail cars meet accident collision, have simultaneously impact protecting function.
The general dynamic device of employing of traditional automatic assembling travel line such as elevator, gear stop device etc., realize that high low speed switches and anticollision.For the small rail car assembling travel line that uses chain to drag, if adopt dynamic high low speed to switch and collision prevention device, then there are the shortcomings such as complex structure, cost are higher.
Summary of the invention
The technical problem to be solved in the present invention is: carry the problems such as first high and low speed switching device complex structure, two small rail cars easily bump in order to overcome existing small rail car, provide a kind of small rail car to switch collision prevention device with high low speed, it is simple in structure, high low speed chain easy switching has solved the anticollision problem simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: a kind of small rail car switches collision prevention device with high low speed, this device is installed on the small rail car, with the top chain in the small rail car, bottom chain and walking slideway are used in conjunction with, this device has a fixing base, fixing base is provided with up and down two cover mechanical mechanisms, every cover mechanical mechanism is equipped with sprocket wheel, separate the circle wheel, limit is turned round device, spring floating bar and rotation mounting rail, spring floating bar one end is installed on the fixing base, the other end is connected with the rotation mounting rail by hinge, the rotation mounting rail other end is hinged on the fixing base, sprocket wheel is fixed to limit and turns round the movable position of device, and limit is turned round device and separated circle and take turns to be connected to by an axle and rotate on the mounting rail.
Described small rail car is provided with track-frame, the top chain that mounted movable speed is different on the track-frame and bottom chain.
Described walking slideway is installed on the track-frame, and matches with round wheel of separating in the upper cover mechanical mechanism.
Described walking slideway is installed on the track-frame, and matches with round wheel of separating in the mechanical mechanism of trapping.
The invention has the beneficial effects as follows: this device has simply solved mechanically the high low speed of dolly and has switched and the anticollision problem, and high low speed switches easily, compares with electric or pneumatic mode, and this mechanism structure is simple, dependable performance, low price.
Description of drawings
Fig. 1 is structural representation of the present invention
Fig. 2 is that the present invention is installed in the structural representation on the small rail car
The specific embodiment
Now by reference to the accompanying drawings and specific embodiment, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1, this device 2 comprise that a fixing base 21 contains sprocket wheel 26 and 210 with two covers, separates circle wheel 28 and 211, limit is turned round device 27 and 29, spring floating bar 23 and 25 and rotate the mechanical mechanisms of mounting rail 22 and 24 compositions.For the top mechanical mechanism, spring floating bar 23 1 ends are installed on the fixing base 21, and spring floating bar 23 other ends are connected with rotation mounting rail 22 1 ends by hinge; The other end of rotation mounting rail 22 is hinged on the fixing base 21; Sprocket wheel 26 is fixed to limit and turns round the movable part of device 27, and limit is turned round device 27 and separated circle and take turns 28 and be connected to by an axle and rotate on the mounting rail 22.For the bottom mechanical mechanism, spring floating bar 25 1 ends are installed on the fixing base 21, and spring floating bar 25 other ends are connected with rotation mounting rail 24 1 ends by hinge; The other end of rotation mounting rail 24 is hinged on the fixing base 21; Sprocket wheel 210 is fixed to limit and turns round the movable part of device 29, and limit is turned round device 29 and separated circle and take turns 211 and be connected to by an axle and rotate on the mounting rail 24.
As shown in Figure 2, a kind of small rail car switches collision prevention device with high low speed, this device 2 is installed on the small rail car 1, small rail car is provided with track-frame 4, the top chain 5 that mounted movable speed is different on the track-frame 4 and bottom chain 6, walking slideway 3 is installed on the track-frame, can separate with any one in the mechanisms of two covers the circle wheel and match and uses (as the bottom slideway of walking being housed among Fig. 2).
The high low speed switch operating principle of this device is: two different chains of speed center on the track up-and-down movement, each station is equipped with the walking slideway that separates the circle wheel for difference according to arts demand, when small rail car is walked certain station (for example the bottom is equipped with and is separated circle wheel walking slideway), the separation circle wheel walking of bottom separates the sprocket wheel that has meshed the bottom along the slideway walking with the bottom chain, simultaneously, the spring floating bar on top stretches out forward under spring-force driven dual, drive the motion of top rotation mounting rail, thereby so that top sprocket wheel and the engagement of top chain, and both not relative motions, like this, the top chain will drag the small rail car motion.
The anticollision principle of work of this device is: sprocket wheel is installed in a mechanical type limit and turns round on the device, when bumping, the pivotable parts that limit is turned round device will temporarily separate, like this, turn round the sprocket wheel that the pivotable parts of device is connected with limit and will skid and do not readvance, thereby prevent the further damage to small rail car.
