On column, Protection switch is installed in the left part of bolt, the feeler lever of Protection switch is put in the door bolt cylinder of bolt.
Although this protective door interlock protection device for material hoist discharging platform has protective door, in material lifting
Protective door may be because that shaking or other reasons are opened during machine is gone up and down, and generate security risk.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of material elevator, protection
Door can only could be opened on material elevator stroke top or bottom end.
To achieve the above object, the utility model provides following technical solution: a kind of material elevator, including carriage with
And the protective door with carriage rotation connection, the two sides of the carriage are symmetrically arranged with locking device；The locking device includes wearing
Cross the side wall of carriage and the limited block that is slidably connected with carriage and the driving assembly for driving limited block sliding；The limited block
Positioned at protective door outside and stop protective door to the outside of carriage rotate；The driving component includes matching of connecting with limited block
Close block, the upper fixed link for being fixed on lift well top and the lower fixed link for being fixed on lift well bottom end, upper fixed link and lower fixation
Bar can be abutted with coordinating block, and sectional area of the coordinating block close to limited block one end is less than the sectional area far from limited block one end.
By using above-mentioned technical proposal, carriage in the process of movement, limited block is located at the outside of protective door, stops
To the outer side to overturn of carriage, people or cargo in carriage stop protective door turning inside out to carriage again, protect at this time protective door
Door can not be opened；When carriage will be moved to the top or bottom end of lift well, upper fixed link or lower fixed link and coordinating block
It abuts, continues to go up and down with carriage, sectional area of the coordinating block close to limited block one end is less than the section far from limited block one end
Product, contacting block with upper fixed link or lower fixation can generate to the sliding far from limit Block direction, and the outside of protective door is detached from
After the blocking of limited block, protective door can not be opened during lifting to the outer side to overturn of carriage, increase and use
Safety.
The utility model is further arranged to: it is characterized by: the bottom end of fixed bar is rotatably connected to upper limit
Wheel, the top of lower fixed link is fixed with lower limit wheel, and lower limit wheel and upper limit wheel are abutted with coordinating block.
By using above-mentioned technical proposal, moved between position-limited wheel rotation reduction coordinating block and upper fixed link or lower fixation

Under the action of, it stretches out carriage 2 and is located at the front side of protective door 21, stop outer side to overturn of the protective door 21 to carriage 2.When carriage is
Will be moved to the top of lift well perhaps bottom end when upper limit wheel 332 or lower limit wheel 322 abutted with arc surface 3131, with
Carriage 2 continue to go up and down, arc surface 3131 can be slided relative to upper limit wheel 332 or lower limit wheel 322, drive sliding bar
312 move to the direction far from protective door 21, and the front side of protective door 21 loses the blocking of limited block 3121, can be to carriage 2
Outer side to overturn.
Referring to fig. 4 and Fig. 5, the inside of carriage 2 are fixed with the block 25 for preventing protective door 21 from rotating to the inside of carriage 2.
Man-operated mechanism 34 includes the skewback 342 that the connecting rod 341 for being fixed on 3122 top of link block and connecting rod 341 are slidably connected.Even
The through-hole 3411 slided for skewback 342 is offered on extension bar 341, the bottom end of skewback 342 is located in through-hole 3411, and through-hole 3411
Width be less than 342 top of skewback width.Side of the skewback 342 far from carriage 2 is inclined-plane 3421, and the bottom end of skewback 342
For the lesser one end of 342 sectional area of skewback；The upper sliding along the vertical direction of skewback 342, be able to drive connecting rod 341 to separate or
It is moved close to the direction of carriage 2.
In conjunction with Fig. 6, skewback 342 passes through the side wall of carriage 2, is offered on the side wall of carriage 2 for the vertical of the sliding of skewback 342
Hole 24 enables skewback 342 to slide on 24 vertical direction of vertical holes.Man-operated mechanism 34 further includes that carriage 2 is arranged in
Inside and the shifting block 343 being fixedly connected with skewback 342, the fixed frame 344 for being fixed on 24 outside of vertical holes and with fixed frame 344
The bolt 345 of grafting.Bolt 345 passes through fixed frame 344 and skewback 342, so that skewback 342 is able to maintain the relatively solid of position
It is fixed.
When original state, bolt 345 is inserted into fixed frame 344 and skewback 342, and skewback 342 can not be in vertical holes 24 at this time
Interior sliding.When needing limited block 3121 mobile from the inside of carriage 2, bolt 345 is extracted, shifting block 343 is being stirred, is driving skewback
342 along 24 slide downward of vertical holes, so that the area that skewback enters in through-hole 3411 gradually increases, drives connecting rod 341 to remote
Direction movement from carriage 2.Connecting rod 341 moves drive to the direction far from carriage 2 and drives link block 3122 to far from carriage 2
Side movement, the limited block 3121 that will be located at the front side of protective door 21 walk, and protective door 21 can be beaten from the inside of carriage 2 at this time
It opens.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
