Abstract
The utility model discloses a stored hopper turnover door with a locking mechanism. The turnover door comprises a pair of turnover door bodies which are arranged on a stored hopper discharging port supporting seat, wherein two edges of the turnover door bodies are connected to rotary shafts on two sides of the supporting seat respectively and fixedly, piston rods which are used for controlling two ends of a cylinder and are arranged on the supporting seat horizontally are connected to the rotary shafts through connecting lug plates respectively and fixedly, locking lug plates are arranged on the rotary shafts on the two sides respectively, pin holes are arranged on end portions of the locking lug plates, positioning holes of which diameters are the same as diameters of pin holes are arranged on the supporting seat on the upper portions of the rotary shafts, and positioning pin shafts penetrate through pin holes and are inserted into positioning holes. The turnover door has the advantages of being simple in structure, convenient and flexible to operate and capable of conducting reliable mechanical locking to turnover door bodies and avoiding the problems that the turnover door is opened mistakenly caused by the mistaken action of the controlled cylinder, stored materials are poured into a main machine suddenly and maintenance personnel gets hurt.
Description
Technical field
The utility model relates to concrete batch plant, especially relates to a kind of pre-storaging bucket plate-turning door with lockable mechanism.
Background technology
When concrete-agitating stood in work, equipment can improper power-off event occur because of various uncertain factors, at this moment following problem can occur at production line: 1, in the main frame just the material at mix also do not have mix even, cause boiling in a covered pot over a slow fire machine; 2, deposited next dish sand material in the pre-storaging bucket in, also do not poured in the main frame.After the problems referred to above occurring, the maintenance personal enters with regard to needs and in time processes stewing machine problem in the main frame, and at this moment primary safety operation is exactly the main power source of Shutdown Hosts.But because the plate-turning door of pre-storaging bucket is to be opened and closed by cylinder control, it is unusual that unexpected power failure can cause control system or electric wiring to occur.After if the maintenance personal enters main frame, cylinder solenoid valve is jerked, and pre-storaging bucket plate-turning door is thrown open, and the sand material moment in the pre-storaging bucket will pour in the main frame, and its consequence must be very serious.
Summary of the invention
The purpose of this utility model is to provide a kind of pre-storaging bucket plate-turning door with lockable mechanism, and when the maintenance personal entered main frame, lockable mechanism can guarantee that plate-turning door is in closed condition, had eliminated the sudden toppling of pre-material stock to maintenance personal's unexpected injury.
For achieving the above object, the utility model can be taked following technical proposals:
Pre-storaging bucket plate-turning door with lockable mechanism described in the utility model, comprise a pair of plate-turning door body that is arranged on the pre-storaging bucket discharging opening bearing, the both sides of described plate-turning door body are connected in respectively in the rotating shaft of bearing both sides, and the piston rod that is horizontally set on the control cylinder two ends on the bearing is connected with described rotating shaft mutually by connecting otic placode respectively; Be respectively arranged with the locking otic placode in the rotating shaft of described both sides, offer pin-and-hole in described locking otic placode end, bearing on described rotating shaft top is provided with the locating hole identical with described pin-and-hole diameter, and alignment pin passes in described pin-and-hole in the described locating hole of rear insertion.
Offer locking hole in the alignment pin near locking otic placode inner side.
Described locking otic placode is the integral type structure with being connected otic placode.
The utility model has the advantage of simple in structurely, easy to operate, flexible, can carry out reliable mechanical locking to turning over sidecar body, stopped to open by mistake because the control cylinder misoperation makes plate-turning door, pre-material stock sudden toppling enters the unexpected injury that in the main frame maintenance personal is caused.

The specific embodiment
Shown in Fig. 1,2,3,4, pre-storaging bucket plate-turning door with lockable mechanism described in the utility model, comprise a pair of plate-turning door body 2 that is arranged on the pre-storaging bucket discharging opening bearing 1, the both sides of plate-turning door body 2 are connected in respectively in the rotating shaft 3 of bearing both sides, and the piston rod 5 that is horizontally set on control cylinder 4 two ends on the bearing 1 is connected with rotating shaft 3 mutually by connecting otic placode 6 respectively; Be respectively arranged with locking otic placode 7 in both sides rotating shaft 3, since locking otic placode 7 be connected otic placode 6 and move simultaneously, so locking otic placode 7 be connected otic placode 6 and can be the integral type structure, offer pin-and-hole 8 in locking otic placode 7 ends, bearing 1 on rotating shaft 3 tops is provided with the locating hole 9 identical with pin-and-hole 8 diameters, the workman is when overhauling the main engine, and alignment pin 10 passes in pin-and-hole 8 in the rear insertion locating hole 9; Alignment pin 10 can not come off from locating hole 9 during for assurance work, offers locking hole 11 in the alignment pin 10 near locking otic placode 7 inner sides, and locking hole 11 interior insertion locking pins (bolt that available diameter is 8 millimeters or L shaped bearing pin) get final product.
When equipment breaks down, the maintenance personal need to enter when overhauling in the main frame, Shutdown Hosts general supply at first, at this moment plate-turning door body 2 is closed, piston rod 5 retractions at control cylinder 4 two ends, pass in the pin-and-hole 8 with alignment pin 10 self-locking otic placodes 7 ends in the locating hole 9 on the rear insertion bearing, locking pin is inserted in the locking hole 11 again, plate-turning door body 2 is carried out reliable mechanical locking, misoperation appears even control cylinder 4 is malfunctioning like this, turn over sidecar body 2 and also can't open, guaranteed to enter the personal safety of maintenance personal in the main frame.
During normal operation, alignment pin 10 is extracted from locating hole 9 and pin-and-hole 8, control cylinder 4 actions, and piston rod 5 is protruding, connects otic placode 6 and promotes rotating shaft 3 rotations, and rotating shaft 3 drives are turned over sidecar body 2 and are opened; The main frame that material in the pre-storaging bucket can fall into the below stirs, as shown in Figure 5.
