The cage connection mechanism comprises a suspension cage and a lifter transmission device, wherein force is transferred between the lifter transmission device and the suspension cage through a weighing sensor, the lifter transmission device is arranged in the suspension cage, a transmission device installation plate is arranged on the lifter transmission device, an installation steel plate is arranged on the suspension cage, connection holes are correspondingly arranged on the transmission device installation plate and the installation steel plate, the transmission device installation plate and the installation steel plate are fixedly connected through a bolt and a nut, a positioning sleeve is sleeved outside the bolt and fixed between the installation steel plate and the bottom surface on the head portion of the bolt, the length of the positioning sleeve is larger than the depth of the connection hole arranged on the installation steel plate, and the external diameter of the positioning sleeve is smaller than the hole diameter of the connection hole arranged on the installation steel plate. The lifter transmission device is arranged into the suspension cage, the effective lifting height of a lifter cannot be lowered, checking and maintenance are facilitated, and an overload protection device is accurate in measuring.
Description
Technical field
The utility model belongs to the elevator technology field, particularly relates to bindiny mechanism in a kind of weight limitor cage.
Background technology
Building hoist all is equipped with overload protection device at present, and this device reply cage is conducted oneself with dignity, cage is interior and cage top load is all effective.All building hoists all adopt the mode of putting on the driving device (driving device are outside cage in the market; and be positioned at directly over the cage) LOAD CELLS that overload protection device is installed, being connected by otic placode and pole-pin type LOAD CELLS between driving device and the cage realizes.It is little that this top load arrangement has in the cage noise, retarder occurs can not polluting cage inside after the leakage of oil, driving device does not take the advantage of cage inner space, also has simultaneously following weak point, effective hoisting depth of elevator can reduce 1-2 rice when same setting height(from bottom), and the maintenance and inspection of driving device are inconvenient.
Summary of the invention
For above-mentioned the deficiencies in the prior art part, the utility model provides bindiny mechanism in a kind of weight limitor cage, and elevator drive mechanism is built in cage inside, can solve the problem that above-mentioned prior art exists fully.
The technical solution adopted in the utility model is:
Bindiny mechanism in a kind of weight limitor cage, comprise cage and elevator drive mechanism, transmit power by LOAD CELLS between elevator drive mechanism and the cage, elevator drive mechanism is located in the cage, the driving device adapter plate is arranged on the elevator drive mechanism, the installation steel plate is arranged on the cage, correspondence is offered connecting bore on driving device adapter plate and the installation steel plate, by bolt and nut driving device adapter plate and installation steel plate are connected and fixed, and the connecting bore aperture on the driving device adapter plate is greater than the connecting bore aperture of installing on the steel plate, the bolt external diameter is less than the connecting bore aperture of driving device adapter plate, bolt coat connects locating bush, locating bush is fixed on to be installed between steel plate and the bolt head bottom surface, and the connecting bore degree of depth on the locating bush Length Ratio driving device adapter plate is long, and the locating bush external diameter is less than the connecting bore aperture on the driving device adapter plate.
As preferably, described driving device adapter plate and correspondence is installed on the steel plate offers 4 pairs of connecting bores.
Traditional elevator drive mechanism is connected with cage by 6 bolts driving device adapter plate and cage is connected and fixed.Have like this weight of considerable part by the tie bolt transmission, thereby cause the final metering of overload protection device inaccurate.The present invention adopts 4 bolts to connect by the driving device adapter plate with the 4 pairs of connecting bores on steel plate is installed, can reduce the metering error of overload protection device as far as possible.
As preferably, the long 1mm of the connecting bore degree of depth on the described locating bush Length Ratio driving device adapter plate.
This structure is so that be in contactless state between locating bush and the driving device adapter plate.
The utility model has the advantage of: simple in structure, reasonable in design, elevator drive mechanism is built in the cage, can not reduce effective hoisting depth of elevator, and makes things convenient for the maintenance and inspection of driving device, and the overload protection device metering is more accurate.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As depicted in figs. 1 and 2, bindiny mechanism in a kind of weight limitor cage, comprise cage 2 and elevator drive mechanism 1, pass through LOAD CELLS 3 transmission power between elevator drive mechanism 1 and the cage 2, elevator drive mechanism 1 is located in the cage 2, driving device adapter plate 6 is arranged on the elevator drive mechanism 1, the steel plate 7 of installation is arranged on the cage 2, correspondence is offered 4 pairs of connecting bores on driving device adapter plate 6 and the installation steel plate 7, by bolt 4 nuts 8 driving device adapter plate 6 and installation steel plate 7 are connected and fixed, and the connecting bore aperture on the driving device adapter plate 6 is greater than the connecting bore aperture of installing on the steel plate 7, bolt 4 external diameters are less than the connecting bore aperture of driving device adapter plate 6, bolt 4 outer socket locating bushs 5, locating bush 5 is fixed on to be installed between steel plate 7 and the bolt head bottom surface, and the long 1mm of connecting bore depth B on the locating bush length C ratio transmission device adapter plate 6, locating bush 5 external diameters are less than the connecting bore aperture on the driving device adapter plate 6.
When being assembled with cage 2, driving device 1 adopt mould that tie bolt 4 is aimed at 4 φ 30 connecting bores on the driving device adapter plate 6, then increase locating bush 5 between bolt 4 and the driving device adapter plate 6, locating bush 5 Length Ratio driving device adapter plates 6 thickness grow 1mm, and locating bush 5 external diameters are φ 23, like this after M16 tie bolt 4 is tightened, bolt 4 just compresses locating bush 5, and driving device adapter plate 6 is not compressed, because the locating bush 5 of external diameter φ 23 is concentric with the connecting bore of driving device adapter plate 6 φ 30, therefore both are in contactless state, bolt 4 can not Transfer of Shear and friction force, this moment, the effect of 4 M16 tie bolts 4 only was to prevent that driving device adapter plate 6 from toppling, if this thing happens, because 5 ratio transmission device adapter plate 6 thickness of locating bush grow 1mm, so the time driving device adapter plate 6 angle that can rotate around the pole-pin type sensor 3 of its bottom 0.05 degree is only arranged, the positive pressure that acts on bolt head only has 0.4kg, and steel and steel are 0.15 there not being the friction coefficient under the condition of lubricant, so the time
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
