Abstract
A deviation preventing device of a hoisting machine comprises a box body (1), a nylon roller wheel (2), an approach switch (6) and a switch seat (7) and is characterized in that the box body (1) is arranged on two sides close to a belt transmission wheel of the hoisting machine. A roller wheel supporting seat (3), a nylon roller wheel shaft (10) and a nylon roller wheel (2) are arranged on the box body (1). The roller wheel supporting seat (3) is fixed on one side of the box body (1) through a nut and a screw rod (5) with a spring (4). A nut end of the screw rod (5) is provided with the switch seat (7). The approach switch (6) is arranged on the switch seat (7). The deviation preventing device can real-timely monitor, discover and prevent deviation accidents caused by deviation of a winnowing pan, prevents failures of the hoisting machine from occurring, and further avoids property loss and personnel damage.
Description
Technical field
The utility model relates to the safety device, particularly a kind of elevator sideslip preventing device of anti-dust explosion of the material vertical transport equipment lifting machine of Feedstuff Enterprises.
Background technology
The dust explosion of Feed Enterprise is the major safety risks of serious harm business property and personal security, and wherein, the gig sassafras that rubs causes that dust explosion is the one of the main reasons of major hidden danger; Gig winnowing pan band from bottom to top high-speed cruising in airtight machine barrel, also granular material is scattered in airtight machine barrel when carrying raw grain at a high speed, the winnowing pan band is offset because other factors cause and causes when rubbing sassafras, form the heating that heats up, when the burning-point that reaches powder or have and just produce the huge dust explosion of power when rubbing the sassafras spark, annual in industry have such accident, caused unnecessary property damage and personal injury to enterprise.
Summary of the invention
The purpose of the utility model technology is to provide a kind of elevator sideslip preventing device, can Real-Time Monitoring, discovery and stop the winnowing pan band that skew occurs and the sassafras accident of rubbing that causes.
The purpose of the utility model technology realizes by following technical scheme, and a kind of elevator sideslip preventing device is made of casing 1, nylon running roller 2 and approach switch 6 and switch seat 7; Casing 1 is arranged near the both sides the belt for lifting machine power wheel, be provided with running roller bearing 3, nylon roller wheel shaft 10 and nylon running roller 2 on casing 1, running roller bearing 3 is fixed on casing 1 one sides by screw rod 5 and the nut with spring 4, nut end on screw rod 5 is provided with switch seat 7, and switch seat 7 is provided with approach switch 6.
When skew occurs in gig winnowing pan band, running roller in casing is subject to the extruding generation laterally offset of winnowing pan band, laterally offset occurs in screw rod simultaneously that connect the running roller bearing, when the induction zone of approach switch is arrived in the position of side-play amount, the switch conduction circuit moves, and reports to the police and cuts off the electricity supply.Guaranteed the safety of equipment operation.The utility model Real-Time Monitoring, discovery also stop the winnowing pan band that skew occurs and the sassafras accident of rubbing that causes, and avoid gig equipment to have problems and cause any property loss and personnel's injury.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is local structure for amplifying schematic diagram in Fig. 1;
Fig. 3 is the utility model casing and inner structural representation thereof.
The specific embodiment
Be below in conjunction with the case of implementing, according to accompanying schematic figure, the utility model technology be elaborated.
A kind of elevator sideslip preventing device of the utility model is made of casing 1, nylon running roller 2 and approach switch 6 and switch seat 7; Casing 1 is arranged near the both sides the belt for lifting machine power wheel, be provided with running roller bearing 3, nylon roller wheel shaft 10 and nylon running roller 2 on casing 1, running roller bearing 3 is fixed on casing 1 one sides by screw rod 5 and the nut with spring 4, nut end on screw rod 5 is provided with switch seat 7, and switch seat 7 is provided with approach switch 6.
The utility model is arranged near the both sides the belt for lifting machine power wheel, when skew occurs in gig winnowing pan band, running roller in casing is subject to the extruding generation laterally offset of winnowing pan band, laterally offset occurs in screw rod simultaneously that connect the running roller bearing, when the induction zone of approach switch is arrived in the position of side-play amount, the switch conduction circuit moves, and reports to the police and cuts off the electricity supply, and has guaranteed the safety of equipment operation.
