Abstract
The invention relates to a safety device of a transmission shaft of a concrete mixer truck, which comprises a protective plate and a U-shaped component, wherein the openings of the U-shaped component are upward. The protective plate extends along a horizontal direction and is connected with a pump bracket; two opening ends of the U-shaped component are arranged at the bottom of the protective plate respectively; and the transmission shaft passes through the middle part of the U-shaped component. When either end of the transmission shaft breaks, the U-shaped component limits the rotation of the transmission shaft in a U-shaped space of the U-shaped component. Therefore, the transmission shaft does not fall off from the U-shaped component so as to break other parts such as a chassis. The safety device effectively prevents damages to the other parts of the concrete mixer truck, such as the chassis, which are caused by the rupture of the transmission shaft.

The specific embodiment
Below in conjunction with accompanying drawing,, will make technical scheme of the present invention and other beneficial effects apparent by the specific embodiment of the present invention is described in detail.
Shown in Fig. 2,3,4, the safety device of transmission shaft of concrete mixer truck of the present invention is the U type spare 61 that makes progress of an opening and the protective plate 62 that is used to install this U type spare 61, two openends 611,612 of U type spare 61 are connected with the bottom of protective plate 62 respectively, generally are to adopt bolt 7 to connect.Among the figure 26 is power takeoff, and its function and action principle are identical with the concrete mixing and transporting car of prior art, so be not described in detail in this.
The fixing of protective plate 62 then utilizes pump support 231 to carry out, and pump support 231 utilizes the carrying effect of pump support 231 that protective plate 62 along continuous straight runs are installed on the pump support 231 and protective plate 62 can be fixed as the carrier of hydraulic oil pump 23.Because it is easy to operate that bolt is linked and packed, to make simply, being connected between protective plate 62 and the pump support 231 generally also adopts bolt 71,72 to connect.Protective plate 62 bottoms are installed U type spare and are supported the U type spare 61 of slinging like this, and power transmission shaft 21 passes in the middle of the U type spare 61 and can only rotate in the U of this U type spare 61 type space, and 61 pairs of power transmission shafts 21 of U type spare have played position-limiting action.When fracture takes place in power transmission shaft 21 any ends, because the position-limiting action of U type spare 61, power transmission shaft 21 can only rotate in the U of U type spare 61 type space, form a cantilever position, so not can from U type spare 61 come off and with other parts such as chassis etc. beat (pounding) bad, prevented effectively because of the damage of drive shafts fracture the generation of other parts vehicle chassis component of concrete mixing and transporting car.
In addition, as shown in Figure 4, for easy for installation, two openends of U type spare 61 stretch out respectively and set out horizontal connecting portion 6111 and 6121, two horizontal connecting portions 6111,6121 are connected with bolt 73,74 respectively with the bottom of protective plate 62.
Above embodiment only is a kind of preferred implementation, as limit in the mechanism as not adopting U type spare, and adopt other structure such as circular-arc locating part also can realize, as long as can to power transmission shaft 21 play limit its activity space and can from locating part, not come off with other parts such as chassis etc. beat (pounding) bad.
Again as shown in Figure 2, for when power transmission shaft 21 is protected, also play the effect of warning, the safety device of transmission shaft of concrete mixer truck of the present invention also can be provided with a warning device.This warning device comprises an alarm mechanism (not shown), a sensor 52.Sensor 52 is arranged at by the power transmission shaft 21 driven flanges, and provides an alarm signal, this alarm signal to be sent to this alarm mechanism to give the alarm when fracture takes place power transmission shaft 21.Alarm mechanism comprises sender unit and signal receiver, and sender unit links to each other with this sensor, and alarm signal is sent to signal receiver, and sends sound and/or light alarm by signal receiver.
Wherein, in conjunction with shown in Figure 1, signal receiver is installed in the driver's cabin 8 of concrete mixing and transporting car, because drawing relation, among the figure and fail to illustrate the concrete installation site of sender unit, signal receiver, as long as but the actual signal receiver can be installed on the place that driver or operating personnel can find or can hear.Mount pad 51 is arranged on the pump support 231 of hydraulic oil pump 23 of this concrete mixing and transporting car and stirs the power transmission shaft 21 driven member flange ends 211 of transportation near this concrete, be that sensor 21 is installed in the position that can sense 211 normal operations of power transmission shaft 21 driven member flange ends, and mount pad 51 generally directly is welded on the pump support 231 of hydraulic oil pump 23, and sensor 52 and sender unit can be fixedly mounted on the mount pad 51 in the lump.
With further reference to shown in Figure 5, Fig. 5 is the alarm flow figure of the safety device of transmission shaft of concrete mixer truck of the present invention.Under the situation that machine runs well, power transmission shaft 21 driven member flange ends 211 run well, the signal that the normal event of the signal that inductor 52 is sensed is delivered to the cab signal receiver is normal, when fracture takes place in power transmission shaft 21 any ends, the driven flange 211 of power transmission shaft will stop operating under external force forces, at this moment sensor 52 detects less than signal, this moment, sender unit was sent to signal receiver with alarm signal, send sound and/or light alarm by signal receiver again, so that driver or operating personnel in time handle, reduce the loss.
Because sensor 52, sender unit and signal receiver all adopt the related elements of prior art, so its action principle also is same as prior art, will no longer describe in detail at this.
As known by the technical knowledge, the present invention can realize by other the embodiment that does not break away from its spiritual essence or essential feature.Therefore, above-mentioned disclosed embodiment with regard to each side, all just illustrates, and is not only.All within the scope of the present invention or the change in being equal to scope of the present invention all be included in the invention.
