Abstract
The utility model relates to a device for preventing a belt from being longitudinally torn. The device comprises a switch and a steel wire rope; one end of the rope is fixed, and the other end is connected to the switch. The device is characterized in that the steel wire rope is mounted above the belt; and a tensioning cushioning device is arranged at one end of the rope. The tensioning cushioning device can be a tension spring (6) or a volute spring with a winding shaft. The device is horizontally mounted at the lower part of the transfer chute of a rubber belt conveyor and above the belt, and is used for detecting hard matters falling down from the chute through the steel wire rope (4); and the belt is stopped by pulling a switch (5) to ensure that the belt can not be torn or scratched. The device has reliable operation and is properly mounted on the chutes with various shapes; and meanwhile, because the deformability of the steel wire rope is strong and the tensioning cushioning device has the cushioning effect, the switch can not be pulled apart. Therefore, the operation of the belt can be easily recovered after the failure is eliminated.
Description
Technical field
The utility model relates to a kind of device that prevents the belt longitudinal tear, and it is mainly used in the travelling apron of enterprises such as mine, metallurgy.
Background technology
Mine, metallurgy etc. play enterprise and use travelling apron to transport various materials in a large number; the hard things such as ironware that belt is mingled with in by material take place through regular meeting and scratch in travelling apron in operational process; belt all took place by longitudinal tear major accident into two in many enterprises, brought heavy losses to enterprise.
For addressing this problem, people have developed some and have prevented the method or the device of belt tearing.Common a kind of belt tearing protection switch on the market for example, this tear switch be mounted in pairs in the belt both sides, couple together by two sections steel ropes.One end of rope is permanently affixed on the Support bracket, and the other end is connected and tears apart on the spring ball of shutting.Two sections steel ropes have formed a C/LOOP consistent with the belt grooved below belt.The belt of exposing or tearing as object suspends in midair, and when sweeping one or two steel ropes, the spring ball is drawn out base, causes that two micro-switchs send alerting signal or turn off conveyer.This protection switch must wait belt to be scratched and tear and have object to suspend in midair just and can move, so reliability is lower, and belt it can not move when being scratched (not tearing).In addition because this device do not have recoil spring, when belt tearing have object touch steel rope often regular meeting draw bad switch because belt feeder has inertia not stop moment, so can not resume production immediately after moving.
Summary of the invention
The purpose of this utility model provides a kind of device that prevents the belt longitudinal tear, it can prevent effectively that belt from vertically being scratched or tearing, its reliable operation, before being scratched, belt just can detect fault, and can not drawn badly after the switch motion, can resume operation immediately behind the trouble removal.
The purpose of this utility model is achieved in that this device comprises switch, steel rope, and an end of steel rope is fixed, and the other end is connected on the switch, and its principal feature is: steel rope is installed in the belt top, and an end of steel rope is provided with the tensioning shock absorber.This tensioning shock absorber can be an extension spring, also can be the scroll-type spring of a spool of tape, and steel rope one end is wrapped on the spool.
When hard things such as bigger ironware are fallen on subordinate's belt from chute; if it will scratch or tear belt; a strong point must be arranged; steel rope in the utility model just is mounted in this supporting point position; therefore; hard thing must touch steel rope; steel rope will drive switch motion; send and shut down and alerting signal,, enough surpluses are provided for the tensile deformation of steel rope because an end of steel rope is provided with the tensioning shock absorber; can not draw bad switch; therefore, after hard thing takes out, switch resetted just can recover belt immediately and move.
In addition, be preferably in switch and be provided with the action direction board, so that when unexpected fracture of steel rope or switch motion, can in time find.
Description of drawings
Accompanying drawing 1 is the installation site cutaway view of an embodiment of the present utility model; Accompanying drawing 2 is structural representations of an embodiment of the present utility model.
In Fig. 1, (1) is the belt that transports material, and (2) are the chutes that connects the superior and the subordinate's belt, and (3) are the hard things that falls from chute, and (4) are the steel ropes that is used to detect the hard thing that may tear belt, and what draw is the bench section.
In figure 22, (2) are the chutes that connects the superior and the subordinate's belt, and what draw among the figure is the section of its two sides side plate, (4) be the steel rope that is used to detect the hard thing that may tear belt, (5) are switches, and (6) are extension springs, (7) be the fixed end support, (8) are the switch terminals supports.
The specific embodiment
(see figure 2) in the present embodiment, whole device is made up of fixed end, switch terminals and steel rope (4).Fixed end is made up of support (7) and extension spring (6), and extension spring (6) is the chief component of tensioning shock absorber; Switch terminals is made up of support (8) and switch (5).During use, fixed end and switch terminals are installed in the outside of the biside plate of chute (2) respectively, use steel rope (4) that both are linked up again.
The Unit Installation position can be with reference to shown in Figure 1 selected, and the position of steel rope (4) should guarantee to have in the chute (2) hard thing (3) can touch it when falling, so that belt (1) is stopped, thereby protection belt (1) is not scratched or tears.
The working process of device is such: when hard thing (3) falls from chute (2), if blocked by chute (2) and belt (1), will scratch or tear belt, but if want to tear belt, it just must have a strong point, and the steel rope in this device (4) just is arranged on this strong point place.Therefore, hard thing (3) must touch steel rope (4), and steel rope (4) is pulled, and drives switch (5) action, sends the belt shutdown signal, thereby the protection belt can not be scratched or tear.
In order to make steel rope (4) that bigger activity surplus be arranged, be provided with extension spring (6) at fixed end, steel rope (4) has just had bigger deformation space like this, and after being convenient to people hard thing (3) being taken out, device can recover standby immediately.
Switch (5) can be machinery limit switch, also can be electronics near switch.
For the ease of using and regulating, can also set up the switch motion direction board in switch terminals.
The switch of above embodiment and tightening device branch are located at the two ends of steel rope, certainly, also both can be installed in together an end of steel rope.
Claims (4)
1, a kind of device that prevents the belt longitudinal tear, it comprises switch, steel rope, and an end of rope is fixed, and the other end is connected on the switch, it is characterized in that: steel rope is installed in the belt top, and an end of rope is provided with the tensioning shock absorber.
2, according to the described device of claim 1, it is characterized in that: the tensioning shock absorber comprises an extension spring.
