But, dragveyer is when working properly, main shaft 1 also can produce distortion or have the situation generation of end float misalignment, like this, main shaft 1 drives sensor block 2 ' to produce and moves axially, and when sensor block 2 ' exceeds the detecting distance of proximity switch 3 ' with the distance of proximity switch 3 ', proximity switch 3 ' can't detect sensor block 2 ', failure alarm signal can be sent out by mistake, cause dragveyer to trip and quit work.
Utility model content
The purpose of this utility model is to provide a kind of chain fault detection system and has the dragveyer of this chain fault detection system, sends out the problem of failure alarm signal for solving checking system of the prior art by mistake.
To achieve these goals, the utility model provides a kind of chain fault detection system, described chain is by carrying out transmission with drive sprocket and engaging of driven sprocket, described chain fault detection system comprises can with at least one sensor block of the main axis of described driven sprocket and for sensing the sensing cell that described sensor block rotates, and described sensing cell is arranged on the outside that described sensor block rotates the circumference formed;
Each described sensor block is the length direction strip consistent with the axis direction of described main shaft, and described sensing cell is set to sense described sensor block when described sensor block moves axially in preset range.
Preferably, the end of described main shaft is provided with detection dish, described sensor block be multiple and along around described main shaft circle spacing be arranged on described detection dish.
Preferably, described sensing cell is proximity switch.
Preferably, described sensing cell is multiple and along around the circumference of described main shaft.
Preferably, described chain fault detection system also comprises the monitoring alarm device be electrically connected with described sensing cell.
The utility model also provides a kind of dragveyer, comprises chain fault detection system as above, and described sensor block is arranged on the main shaft of the driven sprocket of described dragveyer, and described sensing cell is arranged in the frame of described dragveyer.
By technique scheme, can avoid when equipment normally works, due to driven sprocket main shaft deform or end float misalignment time, cause by mistake sending out a chain failure alarm signal, thus cause equipment downtime.
Other feature and advantage of the present utility model are described in detail in detailed description of the invention part subsequently.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for specification sheets, is used from explanation the utility model, but does not form restriction of the present utility model with detailed description of the invention one below.In the accompanying drawings:
Fig. 1 is the structural representation of chain fault detection system in prior art;
Fig. 2 is the structural representation of chain fault detection system in a kind of embodiment of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
The utility model provides a kind of chain fault detection system, chain is wherein by carrying out transmission with drive sprocket and engaging of driven sprocket, this chain fault detection system comprises at least one sensor block 2 that can rotate with the main shaft 1 of driven sprocket and for sensing the sensing cell 3 that sensor block 2 rotates, sensing cell 3 is arranged on the outside that sensor block 2 rotates the circumference formed; Each sensor block 2 is the length direction strip consistent with the axis direction of main shaft 1, and sensing cell 3 is set to sense sensor block 2 when sensor block 2 moves axially in preset range.
The fault detection system that the utility model provides, the main shaft 1 of flower wheel produces distortion in normal operating conditions or produces end float misalignment, due to the strip that sensor block 2 is consistent with main shaft 1 axis direction, so sensor block 2 is when moving axially with main shaft 1, the radial distance be arranged between the sensing cell 3 in the outside of the circumference that sensor block 2 rotation is formed and sensor block 2 is constant, therefore, even if sensor block 2 produces end float misalignment within the specific limits with main shaft 1, sensing cell 3 still can sense sensor block 2, flase alarm phenomenon can not be there is less than sensor block 2 because of the distortion under main shaft 1 normal operation or end float misalignment sensing.
In a specific embodiment, as shown in Figure 2, detection dish 4 can be set in the end of flower wheel main shaft 1, sensor block 2 is provided with multiple, the plurality of sensor block 2 is arranged on this detection dish 4 along the circle spacing around main shaft 1, certainly, sensor block 2 is not limited to be arranged on detection dish 4, also can be set directly on the end face of main shaft 1, as long as rotate with driven sprocket main shaft 1, in chain course of normal operation, sensor block 2 rotates with flower wheel main shaft 1, and sensing cell 3 can receive the rotation information of sensor block 2.
Preferably, sensing unit 3 is set to multiple, and along the circumference around main shaft 1, like this, when sensing unit 3 cisco unity malfunction, detects sensor block 2 by other sensing unit 3, to ensure the normal work of this chain checking system.
In present embodiment, sensing cell 3 is proximity switch, and as in Fig. 2, proximity switch is arranged on the fixed adapter plate 5 of relative main 1, and the sensitive surface of proximity switch is towards the center of main shaft 1, is received the rotation information of sensor block 2 by proximity switch.
