Abstract
Provided is a safety pincer type stopping layer protective device of a lift cage used for transporting workers or goods during building construction, in industrial and mining enterprises and inside a building. The device comprises a pincer seat, pincer blocks, a spring, a movable rod, a pulling piece, an arc block, a lever and a touching block. The pincer seat corresponding to a vertical rod of a guide rail frame is installed on the lift cage, and the two pincer blocks in the pincer seat are respectively arranged on two sides of the vertical rod and keep a certain distance. When vertical normal operation of the lift cage along the vertical rod of the guide rail frame is stopped, users open a cage door, the touching block on the cage door touches the lever and the pulling piece to drive the whole set of mechanism, the two pincer blocks are respectively pressed on the two sides of the vertical rod and form clamping force, and stopping layer protection of the lift cage is achieved. The pulling piece is connected with an overspeed trigger mechanism and a rope breaking trigger mechanism of the lift cage to achieve the protection. The safety pincer type stopping layer protective device is scientific and reasonable in structure, safe and reliable, convenient in assembly, and capable of being widely popularized and used on man lifters and goods lifters.
Description
Technical field
The utility model belongs to the floor stopper that personnel or lifting of goods machine cage are transported in a kind of building operation, industrial and mining enterprises, and particularly a kind of safe jaw type stops a layer fender guard.
Background technology
In the prior art, like the lift bed device that Shandong assists friendly company to produce, its structure is fixing pipe on the cage top; One end of pipe is fixed with the end plate of centre hole, and stage clip and the diameter latch greater than footpath in the stage clip is set in the pipe, after an end of backguy passes the endoporus of centre hole and stage clip of end plate; Be connected with latch; The other end of backguy is connected with connecting lever one end on being arranged on cage, truck dead lever one end on the connecting lever, and the other end of lever receives cage door pouring weight is controlled.Cage stops to certain one deck, and personnel need get into when getting thing in the cage, and the cage door is opened and raise; With cage door configuration pouring weight is descended; Receive lever one end to pouring weight control under the effect of deadweight around fulcrum along with decline, the fixing connecting lever displacement of the other end of lever makes backguy lax, the latch in the pipe is protruding under the effect of stage clip; And be in the special use that is provided with on the elevator guide rails frame and stop on layer cross-arm, stop layer protection.The part but this structure also comes with some shortcomings; Towards tens of layers high level development, the special use that tens of places need be set on the elevator guide rails frame thus stops a layer cross-arm to modern building, is just heading on cross-arm like latch; Can't under the effect of stage clip, stretch out, can not realize stopping layer protection.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned prior art weak point, provides a kind of safe jaw type of elevator craning cage scientific and reasonable for structure, safe and reliable, easy for installation to stop a layer fender guard.The technical scheme of the utility model is: the circular arc piece is set on portable bar, and the pincers seat is gone up the cooresponding pincers piece in the left and right sides and is connected with the two ends of attaching parts respectively, and the circular arc piece is walked around at the middle part of attaching parts; The briquetting that is provided with on the portable bar connects draw piece one end, and the other end of draw piece connects lever, the corresponding collision block of an end of lever; Clamp seat and go up the vertical rod of corresponding guide rail bracket between the cooresponding pincers piece in the left and right sides, and keep certain distance respectively with the vertical rod both sides; When cage is parked in the guide rail bracket arbitrary height, open cage collision block shake-up lever drives sleeve mechanism behind the door, the cage stop that will stop is on guide rail bracket.In order to obtain better effect; The utility model can also adopt following technical measures: the driving lever that corresponding left and right pincers piece is set respectively on the portable bar; One end of left and right attaching parts is set respectively on the driving lever, and the other end of left and right attaching parts is provided with left and right pincers piece respectively.
Description of drawings
Accompanying drawing is the example structure scheme drawing of the utility model.
The specific embodiment
Embodiment: portable bar 7 and pincers seat 5 that circular arc piece 8 and briquetting 9 have been set are installed on cage 2; In the pincers seat 5 the cooresponding youngloop bending pliers piece 4 that is in the left and right sides is set; About pincers piece 4 under the combined action of spring 3, attaching parts 6 and circular arc piece 8, keep the gap; The vertical rod of guide rail bracket 1 is set between the gap, and keeps certain distance respectively with the vertical rod both sides.Cage 2 is along guide rail bracket 1 vertical rod up-down operation the time, and the cooresponding pincers piece 4 in the left and right sides can not rub.Briquetting 9 on the portable bar 7 is an end of draw piece 13 fixedly, and the other end of draw piece 13 connects lever 10, the collision block 11 on the corresponding cage door 12 of an end of lever 10.Its process was when the utility model used in reality: the cage 2 of having closed cage door 12 drives under the effect of hoisting rope 14 at power 15, goes up and down to move along the vertical rod of guide rail bracket 1.Pincers piece 4 is under the combined action of spring 3, attaching parts 6 and circular arc piece 8 about on the pincers seat 5, keeps the gap with the vertical rod of guide rail bracket 1 and do not rub.When cage 2 when arbitrary height is stopped transport row, after personnel need get into cage 2 and open cage door 12, collision block 11 made cooresponding lever 10 actions and pulling draw piece 13 rotate portable bars 7.The circular arc piece 8 that rotates with portable bar 7 promotes the elastic force that attaching partss 6 and the cooresponding pincers piece 4 in the left and right sides overcome spring 3, about pincers piece 4 under the effect on pincers seat 5 inclined-planes, upwards slide respectively and draw close to the vertical rod of guide rail bracket 1.Behind this moment and the pincers piece 4 elimination gaps of the little side in vertical rod gap, at first contact, compress the end that vertical rod stops to go up sliding and control linkage part 6 and rise, slidingly eliminated certain clearance, also have the gap though gone up with another big piece pincers piece 4 of vertical rod gap.Under portable bar 7 rotates; Attaching parts 6 is sliding on the elastic force that motion on the circular arc piece 8 and the other end bonded assembly pincers piece 4 that continue to promote attaching parts 6 overcome spring 3 continues; Eliminate the opposite side of contact vertical rod behind whole gaps and compress; At this moment pincers piece 4 produces Clamping force to vertical rod simultaneously about, realizes layer protection that stop of cage.Draw piece 13 connects an end of lever 10 and is connected with the hypervelocity of elevator craning cage, disconnected rope trigger mechanism, can realize above protection.The driving lever 16 of corresponding left and right pincers piece 4 is set respectively on the alleged portable bar 7 of the utility model, an end of left and right attaching parts 6 is set respectively on the driving lever 16, the other end of left and right attaching parts 6 is provided with left and right pincers piece 4 respectively.
The utility model and prior art relatively, have scientific and reasonable for structure, safety guard-safeguard is reliable, characteristics such as quick and easy for installation, for existing industry and the civilian personnel of transporting or lifting of goods machine provide a kind of safe jaw type of cage to stop a layer fender guard.
