Abstract
The utility model discloses a take lift protection's grain conveying equipment relates to grain feelings check out test set field, adopts the gas pole to be lift protection device, and cooperation lift arm can effectively ensure equipment and personal safety. One end of the air rod is rotatably arranged at the bottom of the conveying belt through the support arranged on the body of the conveyor, and the other end of the air rod is rotatably arranged on the cross beam of the lifting arm. When a traction rope of the winch contracts and the lifting arm upwards rotates towards the direction of the winch, the air rod is stretched, and at the moment, outside air enters the air rod; when the haulage rope of hoist engine extends, when the lifing arm revolves down, the gas pole receives the extrusion and contracts, and the air is slowly discharged from the valve in the gas pole this moment, plays buffering and guard action. When the haulage rope breaks suddenly, the gas in the gas pole can't be discharged from the valve fast, and the contraction rate of gas pole is comparatively slow, plays the effect of buffering, reduces the falling speed of lifing arm and conveyer belt, avoids the circumstances such as lifing arm derail to take place, can effectively protect equipment and personnel's safety.
Description
Technical Field
The utility model relates to a grain haulage equipment field further relates to a take grain conveying equipment of lift protection.
Background
Grain is failed grain conveying equipment and is adopted hoist engine and lifing arm etc. to realize grain conveying equipment's conveyer belt lift, when the conveyer belt rose, the weight majority was applyed on the haulage rope of hoist engine, if maintenance or inspection do not in place, the haulage rope fracture appears easily among the lift process, under the action of gravity, the lifing arm slides forward fast, because of speed is very fast, the lifing arm can't effectively be blocked to the terminal stopper of guide rail, lead to grain conveying equipment whole to collapse, when personnel are under conveying equipment operation or when walking, lack reaction time, there is the casualty risk, equipment also will seriously damage simultaneously.
Disclosure of Invention
The utility model provides a take lifting protection's grain conveying equipment, aim at solves the above-mentioned problem that exists among the prior art.
The utility model adopts the following technical scheme:
a grain conveying device with lifting protection comprises a conveying belt, a lifting arm and a winch, wherein one end of the lifting arm is pivoted to a travelling mechanism, the other end of the lifting arm is connected to the conveying belt in a sliding mode through a rail, the winch is fixedly arranged on the conveying belt, and a traction rope of the winch is connected to the lifting arm; the lifting protection device comprises a telescopic rod, one end of the telescopic rod is hinged to the conveying belt, and the other end of the telescopic rod is hinged to the lifting arm.
Further, the telescopic rod is an air rod.
Specifically, the gas lever comprises a cylinder barrel and a piston rod, the piston rod is telescopically inserted into the cylinder barrel, and the rodless cavity of the cylinder barrel is provided with at least one air hole.
More specifically, the cylinder of the air rod is hinged to the beam of the lifting arm, and the piston rod of the air rod is hinged to the support of the conveying belt.
From the above description to the structure of the present invention, the present invention has the following advantages:
the utility model discloses a gas pole is lift protection device, and the cooperation lifing arm can effectively ensure equipment and personnel's safety. One end of the air rod is rotatably arranged at the bottom of the conveying belt through the support arranged on the body of the conveyor, and the other end of the air rod is rotatably arranged on the cross beam of the lifting arm. When a traction rope of the winch contracts, the lifting arm upwards rotates towards the direction of the winch, the air rod is stretched when the conveying belt ascends, and at the moment, outside air enters the air rod; when the haulage rope of hoist engine extends, the lifing arm is down-rotated, and the conveyer belt descends, the air pole receives the extrusion and contracts, and the air slowly discharges from the valve in the air pole this moment, plays buffering and guard action. When the haulage rope breaks suddenly, the gas in the gas pole can't be discharged from the valve fast, and the contraction rate of gas pole is comparatively slow, plays the effect of buffering, reduces the falling speed of lifing arm and conveyer belt, avoids the lifing arm derail, and the circumstances such as equipment slumps take place, can effectively protect equipment and personnel's safety.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1, the grain conveying equipment with lifting protection comprises a conveying belt 1, a lifting arm 9 and a winch 2. A running mechanism 8 connected with the conveyer belt 1 is arranged below the conveyer belt 1, and the running mechanism 8 mainly comprises a front roller group 81 and a rear roller group 82. The lower end of the lifting arm 9 is pivoted to the bracket of the rear roller group 82 of the traveling mechanism 8, and the other end is connected to the conveyor belt 1 in a manner of being capable of sliding back and forth through a rail 4 arranged at the bottom of the conveyor belt 1. The hoist 2 sets firmly in the bottom of conveyer belt 1 through mounting bracket 11, and the haulage rope 3 of hoist 2 connects on the crossbeam 5 of lifing arm 9.
As shown in fig. 1, the utility model discloses still include lift protection device, this lift protection device mainly includes telescopic link 6, and the one end of telescopic link 6 articulates in conveyer belt 1, and the other end articulates in lifing arm 9.
As shown in fig. 1, specifically, the telescopic rod 6 is an air cylinder, and includes a cylinder 61 and a piston rod 62, the piston rod 62 is telescopically inserted into the cylinder 61, and the rodless cavity of the cylinder 61 is provided with at least one air hole 611. The piston rod 62 is hinged to the support 7 of the conveyor belt 1 and the cylinder 61 is hinged to the cross beam 5 of the lifting arm.
The above-mentioned be the utility model discloses a concrete implementation way, nevertheless the utility model discloses a design concept is not limited to this, and the ordinary use of this design is right the utility model discloses carry out immaterial change, all should belong to the act of infringement the protection scope of the utility model.
