Description

Hang scale hooper gate limit control system in port

Technical field

The utility model relates to gate control equipment technical fields more particularly to a kind of port to hang the limit control of scale hooper gate System.

Background technique

Port hangs on and typically contains multiple scale hoopers in material belt line, to improve the hanged material in harbour port, feeding operating rate.To keep away Exempt from belt line in feeding process to be killed by material, is that any one scale hooper breaks down in process control, whole feeding Belt line can all report an error shutdown automatically.And it is highest, serious system that scale hooper fault gate rate is hung in feeding system at entire port About the raising of port crane operation rate.

Scale hooper gate limit controller is hung as shown in Figure 1, it is formed by three close to switch combination, and is passed through in original port Rigid rod is welded on scale hooper, and a touch points are welded on gate, and touch points are successively with three during gate open and close movement It is a close to switch contact, transmit it is complete close, half-open, three signals of standard-sized sheet.Charging belt line when dropout, dual signal, three signals Will stoppage protection avoid scale hooper failure from material occur and kill belt or belt being torn to shreds.

The above scale hooper gate limit controller is often there arises a problem that (1) is since scale hooper vibration motor is in feeding Constantly vibration in the process, nut fastening generate displacement close to easy loosen of switch, signal deletion occur and cause belt line stoppage in transit； (2) port is hung on during material due to materials from spattering, when magnetic material is touched close to switch, dual signal even three signals occurs Belt line is caused to stop transport；(3) when breaking down close to switch, maintenance personal needs first to stop belt line, then gets into gate and skin Narrow position between band carries out upkeep operation.

Utility model content

Technical problem to be solved by the utility model is: being easy pine close to switch to understand due to scale hooper motor oscillating , there is signal deletion and causes belt line stoppage in transit problem in the raw displacement of movable property；Port hang on material during due to materials from spattering, work as magnetic material When touching close switch, there are dual signal even three signals and cause belt line stoppage in transit problem；When breaking down close to switch, maintenance Personnel need first to stop belt line, and the small space then got between gate and belt carries out upkeep operation, and operating environment is severe While there are problems that security risk, the utility model provides a kind of port and hangs scale hooper gate limit control system.

The technical scheme adopted by the utility model to solve the technical problem is as follows: the limit control of scale hooper gate is hung at a kind of port System, including scale hooper and Electrohydraulic push rod, the scale hooper are mounted on scale hooper column, are provided in the lower port of scale hooper Gate is opened and closed, the folding gate includes active gate and driven gate, and the upper end of active gate and scale hooper are by actively turning Axis rotation connection, the upper end of driven gate and scale hooper are rotatablely connected by driven spindle, are set with driving tooth on active rotating shaft It takes turns, driven gear, active rotating shaft and driven spindle is set on driven spindle and is intermeshed by driving gear and driven gear, When active gate and driven gate are closed, the lower port of scale hooper is closed, when active gate and driven gate are opened, scale hooper Lower port it is open, Electrohydraulic push rod is fixed on scale hooper outer wall, the extension end of Electrohydraulic push rod and the outside activity of active gate It connects, is further fixedly arranged on hex nut on the outside of the driven gate, scale hooper gate limit control system is hung also in the port Including fixed pulley, ballast box, clump weight, wirerope and calculator, the fixed pulley is fixedly installed on the top of hex nut, matches Loaded van is fixed on scale hooper column, and ballast box is located at below fixed pulley, and clump weight is arranged in ballast box, one end of wirerope Be fixedly connected with hex nut, the other end of wirerope bypasses the top of fixed pulley, be then passed through ballast box top vertical downwards and Clump weight connection, the side of ballast box are installed from top to bottom there are three close to switch, and three connect close to switch and calculator through signals It connects, three separately detect active gate and the full pass of driven gate, half-open and three states of standard-sized sheet, calculator and electricity close to switch The connection of liquid push rod signal.

In order to guarantee to weigh the transmission of bucket material, vibration excitor is also equipped on the scale hooper.

In order to guarantee wirerope stable turning, it is fixed sliding that changed course is further fixedly arranged between the fixed pulley and hex nut Wheel, changed course fixed pulley and fixed pulley are contour.

The utility model has the beneficial effects that scale hooper gate limit control system is hung at the port of the utility model, steel is utilized Cord one end is fixed on the hex nut of gate, and the other end connects stainless steel clump weight, will be former by two changed course fixed pulleys Originally the limit controller being mounted on gate is transferred on scale hooper column, is converted clump weight for the opening and closing movement of gate and is being matched Upper and lower reciprocating motion in loaded van, full pass, half-open, standard-sized sheet signal are transferred to computer and sentenced by three respectively close to switch Do not control, it made to have completely disengaged the severe working environment of situ, as the continual continuous vibration of scale hooper vibration motor, Limit controller is down to zero close to switch physical damage rate and vibration displacement problem by the collision of material during material feeding；? Close to switch service life to when limit replacement, it is not necessary to which stop entire charging belt line, improves port crane operation efficiency, while employee Also small space replacement operation between scale hooper and belt need not be pierced, while improving working efficiency, safety coefficient is higher.
