Description
Technical field
This utility model belongs to belt transmission protection device field, and the anti-longitudinal tear of more particularly, to a kind of four-in-one belt is protected
Protection unit.
Background technology
Belt, during transported material, is mixed into the debris such as metal sharp weapon and may scratch tear belt in material, longitudinally
Tearing protective device is a kind of protection device reducing the tear of belt distance.Protective device against longitudinal tear generally by sensor and
Control chamber two parts form, and sensor is preferably installed on rubber conveyer and is subject to below shots, and sensor is as the detection of longitudinal tear
Element, after the belt of belt conveyor is pierced through by foreign body, material falls on sensor, and at this moment signal is delivered to control by sensor
Case, control relay action, send warning and stop sign, thus realizing the protective effect to belt.But this longitudinal tear
Protection device just can send alarm signal only until after belt tearing falling material on sensor, causes tear protection dress
Put not sensitive, can not perfectly solve upper belt tear, upper belt torn edges, lower belt strip, lower belt torn edges, lower belt
The problems such as sideslip weares and teares.The patent of patent No. 201320819946.x, designs protecting longitudinal rupture using dynamic balancing lever principle
Device, the position adjusting counter weight makes pallet and counter weight be equilibrated at horizontal level at spillplate two ends, has in belt tearing
Material is all broken initial balance and is triggered tearing protective device action when dropping on weight, striker plate or pallet, this device
Tear protection act can be produced at the belt tearing initial stage from the non-horizontal poised state of whole device, so that this tear
Protection is sensitiveer, but this device adopts dynamic balancing lever principle to design, and occasional, because the reason such as vibration equipment is big, can be made
Become tearing protective device misoperation；When tear phenomenon occurs, there is material to get on pallet or during striker plate, can cause entirely to tear guarantor
Protection unit overturns, and on the contrary because the upset of protective device against longitudinal tear, balancer shaft can be possible to rub on the belt of bottom, can make on the contrary
Become the bigger injury of belt.
Content of the invention
This utility model is to solve the above problems, and devises the anti-longitudinal direction of a four-in-one belt using static balance lever principle and tears
Split protection device.
Technical solution adopted in the utility model:
The anti-protective device against longitudinal tear of four-in-one belt, including pallet, upper belt protective cradle set, tear switch spindle,
Balancer shaft, backgauge board shaft, bottom belt protection support casing and sensor, described pallet and balancer shaft are individually fixed in tear switch
The main shaft left and right sides, balancer shaft arranges counter weight, and counter weight can be moved back and forth along balancer shaft, upper belt protective cradle
Set and bottom belt protection support casing are welded on the tear upper and lower both sides of switch spindle, and tear switch spindle two ends are respectively provided with band base
Bearing, setting alignment pin by the band base bearing of tear switch spindle one end, backgauge board shaft is welded on below tear switch spindle, on
On belt protection support casing and bottom belt protection support casing, upper belt fender bracket and bottom belt protection are respectively fixed with by screw
Frame, bottom belt protection frame can make the bracing frame of balancer shaft holding level in the welding of balancer shaft one side-lower, described sensing
Device is connected with pallet and belt drive unit respectively.
In described backgauge board shaft, striker plate is fixed with by fixed cover and bolt.
Some bar holes are opened on described pallet.
Described counter weight is bolted with counterweight between centers.
The beneficial effects of the utility model: this utility model can be produced by the non-standard state of device at the tear initial stage
Raw tear protection act, and alignment pin, when triggering tearing protective device action, the stuck tear of alignment pin are increased on main shaft
Protection device, forbids that balancer shaft significantly overturns the tear leading to belt bigger, increases on the lower belt support frame of configuration axle side
Plus bracing frame, so that balancer shaft is pressed on bracing frame, keep both sides to be in level, prevent the vibration of belt installing rack or some reasons
Lead to tearing protective device to break poised state, lead to misoperation, increase bottom belt protection frame, reduce the bigger torn edges of bottom belt
Phenomenon.
