Description

TECHNICAL FIELD

[0001] The utility model relates to synchronous belt detection field, specifically a synchronous belt breakage detection device. BACKGROUND

[0002] The shuttle vehicle runs in the passageway of the stereoscopic warehouse, stores the goods (material box) at the lane mouth into the goods grid of the goods shelf, or takes out the goods in the goods grid and transports to the lane mouth.

[0003] Synchronous belt: it is a kind of ring-shaped belt with steel wire rope or glass fiber as power layer, and polyurethane or neoprene rubber is covered outside, the inner periphery of the belt is made into a tooth shape, so that it is meshed with the toothed belt wheel transmission.Synchronous belt transmission is through the meshing of belt teeth and tooth groove of belt wheel, realizes the precise transmission without slip, and the transmission ratio is accurate and constant.

[0004] The lifting system of the shuttle vehicle usually adopts double synchronous belt transmission design, however, the synchronous belt is prone to breakage or relaxation after long-term use.

[0005] The main reason for synchronous belt breakage is that the tooth surface is seriously worn after long-term operation, resulting in the decrease of the strength of the belt body.

[0006] The main reason for synchronous belt relaxation is that the initial tension of the synchronous belt is insufficient during installation, resulting in that the belt body is too loose, or the belt body is gradually stretched due to material fatigue and wear during long-term operation, resulting in the decrease of tension.

[0007] For the above problems, the current monitoring method is mostly through naked eye observation and touch by people, and the broken belt and insufficient synchronous belt tension cannot be found in time, resulting in sudden shutdown risk and increased maintenance cost.

[0008] In view of the above problems, the utility model provides a synchronous belt breakage detection device to complete the breakage detection of the synchronous belt. Utility model content

[0009] The utility model aims at providing a synchronous belt breakage detection device to solve the above problems existing in the prior art.

[0010] Technical scheme: a synchronous belt breakage detection device, comprising:

[0011] The trigger part comprises a base, a trigger piece movably arranged on the base, and the trigger piece comprises a trigger piece;

[0012] The receiving part comprises a micro switch abutting against the trigger piece, and the trigger end of the micro switch is provided with a roller abutting against the trigger piece in rolling mode.

[0013] The trigger piece is connected with the end part of the open loop synchronous belt.

[0014] The trigger plate has a chamfer at a predetermined angle near the end of the roller.

[0015] The base and micro switch are both installed on the lifting platform of the shuttle trolley's lifting system.

[0016] When in use, the micro switch can be connected to the control terminal of the shuttle car to complete the shutdown operation.

[0017] This invention uses a design where a trigger plate contacts a micro switch to detect whether the synchronous belt has broken. When the synchronous belt breaks, the trigger is not under force and descends, causing the trigger plate to descend and contact the roller, which in turn causes the trigger end to extend and retract, thus completing the belt break detection.

[0018] In a further embodiment, the base is concave, and guide bolts and clamping bolts are respectively provided at both ends of the base;

[0019] A rectangular spring is connected between the clamping bolt and the base. By designing the rectangular spring, the open-loop synchronous belt has a certain tension. At the same time, when the open-loop synchronous belt breaks, the trigger plate can contact the roller more quickly, and the trigger end of the micro switch can retract to complete the triggering of the micro switch.

[0020] When the timing belt is slack, since one end of it is connected to the toothed block, the toothed block is affected by the spring tension, which tightens the timing belt and provides tension to the timing belt.

[0021] In a further embodiment, the trigger includes:

[0022] Toothed blocks;

[0023] The pressure plate is connected to the toothed block;

[0024] The pressure plate is connected to the toothed block by fixing bolts.

[0025] In use, the toothed portion of the open-loop synchronous belt is engaged with the toothed block, and the pressure plate and the toothed block are connected by fixing bolts to fix the open-loop synchronous belt between the toothed block and the pressure plate.

[0026] In a further embodiment, the toothed block abuts against the guide bolt and is threadedly connected to the clamping bolt.

[0027] In a further embodiment, the toothed block has guide grooves and threaded grooves at both ends;

[0028] The guide bolt includes a guide thread body that is screwed to the base, and a guide smooth body that is connected to the guide thread body and extends into the guide groove;

[0029] The principle of the guide thread body is that one end of the guide smooth body is provided with a guide hexagonal bolt head.

[0030] The clamping bolt includes a clamping threaded body adapted to the threaded groove, and a clamping smooth body connected to the clamping threaded body and slidingly engaged with the base.

[0031] The clamping bolt has a clamping hexagonal bolt head at one end near the clamping smooth body.

[0032] The rectangular spring is sleeved on the pressing smooth body.

[0033] In a further embodiment, the trigger plate is mounted on the pressure plate.

[0034] Beneficial effects: This utility model discloses a synchronous belt breakage detection device. This utility model detects whether the synchronous belt has broken by designing a trigger piece to contact a micro switch. When the synchronous belt breaks, the trigger is not under force. At this time, the trigger falls down, which drives the trigger piece to fall down and then contact the roller, causing the trigger end to move in a telescopic motion, thereby completing the belt breakage detection work.

[0039] This application relates to a synchronous belt breakage detection device, which will be explained in detail below through specific embodiments.

[0040] A timing belt breakage detection device, comprising:

[0041] The triggering part includes a base 1 and a trigger member movably disposed on the base 1, the trigger member including a trigger piece 4;

[0042] The receiving part includes a micro switch 9 that abuts against the trigger piece 4, and the trigger end of the micro switch 9 is provided with a roller that rolls against the trigger piece 4;

[0043] The trigger is connected to the end of the open-loop synchronous belt;

[0044] The trigger plate 4 has a chamfer at a predetermined angle near the end of the roller.

[0045] Both the base 1 and the micro switch 9 are installed on the lifting platform of the shuttle trolley's lifting system.

[0046] When in use, the micro switch 9 can be connected to the control terminal of the shuttle car to complete the shutdown operation.

[0047] The micro switch 9 is a telescopic micro switch 9, and the trigger end is a telescopic rod.

[0048] This invention uses a design where a trigger piece 4 contacts a micro switch 9 to detect whether the synchronous belt has broken. When the synchronous belt breaks, the trigger is not under force and descends, causing the trigger piece 4 to descend and contact the roller, which in turn causes the trigger end to extend and retract, thus completing the belt break detection.

[0049] The base 1 is concave, and guide bolts 8 and clamping bolts 6 are respectively provided at both ends of the base 1;

[0050] A rectangular spring 5 is connected between the clamping bolt 7 and the base 1. By designing the rectangular spring 5, the open-loop synchronous belt has a certain tension. At the same time, when the open-loop synchronous belt breaks, the trigger piece 4 can contact the roller more quickly, and the trigger end of the micro switch 9 can retract to complete the triggering of the micro switch 9.

[0051] When the timing belt is slack, since one end of it is connected to the toothed block 2, the toothed block 2 is affected by the spring tension, which tightens the timing belt and provides tension to the timing belt.

[0052] At the same time, the tension of the spring can drive the clamping bolt 6 to move, increase the descent speed of the toothed block 2, reduce the detection response time, and improve the detection efficiency.

[0053] The trigger includes:

[0054] Toothed block 2;

[0055] Pressure plate 3 is connected to the toothed block 2;

[0056] The pressure plate 3 is connected to the toothed block 2 by fixing bolts 7.

[0057] In use, the toothed portion of the open-loop synchronous belt is engaged with the toothed block 2, and the pressure plate 3 is connected to the toothed block 2 by the fixing bolt 7, thus fixing the open-loop synchronous belt between the toothed block 2 and the pressure plate 3.

[0058] The toothed block 2 abuts against the guide bolt 8 and is threadedly connected to the clamping bolt 6.

[0059] The toothed block 2 has guide grooves and threaded grooves at both ends;

[0060] The guide bolt 8 includes a guide thread body that is screwed to the base 1, and a guide smooth body that is connected to the guide thread body and extends into the guide groove;

[0061] The principle of the guide thread body is that one end of the guide smooth body is provided with a guide hexagonal bolt head.

[0062] The clamping bolt 6 includes a clamping threaded body adapted to the threaded groove, and a clamping smooth body connected to the clamping threaded body and slidingly engaged with the base 1.

[0063] The clamping bolt 6 has a clamping hexagonal head at one end near the clamping smooth body.

[0064] The rectangular spring 5 is sleeved on the pressing smooth body.

[0065] The trigger plate 4 is mounted on the pressure plate 3.

[0066] Working principle description: During operation, one end of the open-loop synchronous belt is installed between the pressure plate 3 and the toothed block 2, and the adjusting guide bolt 8 and the clamping bolt 6 are adjusted to connect the toothed block 2 to the base 1.

[0067] When the synchronous belt is intact, it holds the pressure plate 3 and the toothed block 2. When the synchronous belt breaks, the pressure plate 3 and the toothed block 2 are no longer under force and descend. At this time, they come into contact with the roller and cause the trigger end of the micro switch 9 to extend and retract, thus completing the belt break detection.

[0068] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
