Abstract
The utility model relates to a construction elevator, in particular to a load detection and overload protection device of a split-type construction elevator, which has simple structure, lower cost, stronger reliability and better safety. The load detection and overload protection device is provided with a transmission mechanism bracket, a suspension cage, two groups of flange plates, two vertical plate seats, two groups of shaft pin-type sensors and two groups of screws, wherein the flange plate is double-vane type; the flange plates are welded at the lower part of the transmission mechanism bracket; the two vertical plate seats are welded at the top of the suspension cage; the flange plate and the vertical plate seat are each provided with a sensor hole and a screw hole; the sensor hole is arranged above the screw hole; the shaft-pin type sensors are connected with the flange plates and the vertical plate seats; and the transmission mechanism bracket is integrated with the suspension cage. The utility model has the advantages that the load detection of the suspension cage can be realized, and the overload protection also can be realized. In addition, the utility model also has the advantages of high safety, strong reliability, simple structure and low cost.
Description
Technical field
The utility model relates to a kind of building hoist, and the load that especially relates to a kind of split type building hoist detects and cross the load fender guard.
Background technology
Building hoist is a kind of jacking equipment that is used for vertically transporting workmen and building materials at construction site.Especially in the camp site of skyscraper, the construction lifting is as a kind of main personnel and building material transportation means, and its safe in operation is particularly important.If in a single day elevator has an accident, often cause personal injury.National departments concerned is being done strict regulations aspect the safe operation of elevator, no matter be the safety protection function aspect of equipment itself, still comparatively strict regulation is being arranged all aspect user's the use.But the elevator major part in a lot of camp sites does not all have load to detect and crosses the load defencive function, or guard method is too simple, often causes accident on duty.Building hoist can be divided into split type and integral type on structure, the split type transmission device that is meant is contained in the cage top, hangs cage by transmission device; Integral type is meant that transmission device is installed in cage in-to-in structure.The loading testing method of split type employing is to connect transmission device and cage with two axial pin type sensors mostly, and axial pin type sensor is as unique parts of test load and carrying cage weight.But the axial pin type sensor work under bad environment, since its long-term work, the labor intensity height, and detecting data reliability can descend with period of service; Therefore in the course of the work, may the mistake load that produce cause the load detecting device fracture, cause accident on duty because the urgency of elevator stops whipping.
Chinese patent CN2266582 provides a kind of pinion and-rack elevator, its guide rail bracket directly is fixed on the wall by attaching parts, cage with guide wheel with the guide rail bracket combination, two drive motor and overrun brake are housed in the cage, drive motor one end is equipped with retarder, and by the wheel and rack engagement, the other end is equipped with magnet stopper, and manual clamping handle is housed on the magnet stopper.Wheel and rack engagement on the overrun brake.The cage bottom is two layers, and the spring on upper strata is supported on the bottom, between two layers limit switch is housed, and prevents overload.Have and operate steadily, noiselessness saves material, characteristics such as safety factor height.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, cost is lower, reliability is strong, safety preferably the load of split type building hoist detect and cross the load fender guard.
The utility model is provided with drive motor framework, cage, 2 groups of flanges, 2 riser seats, 2 groups of axial pin type sensors and 2 groups of screw rods.Described flange is a double-valve type, and flange is welded on drive motor framework bottom; 2 riser seats are welded on the cage top; Be equipped with gauge hole and screw on described flange and the riser seat, gauge hole is positioned at the screw top; Axial pin type sensor is connected with the riser seat with flange, and drive motor framework and cage are formed one.
Described axial pin type sensor and flange and riser seat can adopt flush fit.Axial pin type sensor had both played interconnect function like this, the more important thing is the weight that can detect cage.
Described screw rod and flange and riser seat can adopt free-running fit.
Under normal operation, the load of having only axial pin type sensor to bear cage guarantees that like this load weight that sensor is read is the actual weight of cage, can make overload warning truly.But because long-term work, the labor intensity height can produce fatigue accumulation or fatigue damage, and the urgency of elevator stops whipping in addition, can produce increment load, and long-term accumulation may cause the fracture of axial pin type sensor to cause accident on duty.Add that screw rod as crossing the load fender guard, just can prevent the generation of this class accident.After the axial pin type sensor fracture, screw rod plays the effect of connection, carrying cage.At this moment, the suffered load of screw rod can be bigger, and for guaranteeing safety, selecting for use of screw rod requires its load-carrying capacity greater than axial pin type sensor.
The utility model both can have been realized the detection of cage load, also can realize the load protection, safe, good reliability, and simple in structure, cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structural representation of flange among the utility model embodiment.
Fig. 3 is the structural representation of the riser seat on the cage among the utility model embodiment.
In Fig. 1～3,1 cage, 2 riser seats, 3 flanges, 4 drive motor frameworks, 5 axial pin type sensors, 6 screw rods.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present invention is further described.
Referring to Fig. 1～3, the utility model embodiment is provided with drive motor framework 4, cage the 1, the 1st flange the 31, the 1st riser seat the 21, the 1st axial pin type sensor the 51, the 1st screw rod the 61, the 2nd flange the 32, the 2nd riser seat 22, the 2 axial pin type sensors 52 and the 2nd screw rod 62.The 1st flange 31 and the 2nd flange 32 all are welded on drive motor framework 4 bottoms.The 1st riser seat 21 and the 2nd riser seat 22 all are welded in cage 1 top.2 flanges and 2 riser seats all are provided with gauge hole and screw, and gauge hole is positioned at the screw top.2 axial pin type sensors and 2 flanges and 2 riser seats adopt flush fit, and drive motor framework 4 and cage 1 are formed one, and axial pin type sensor had both played interconnect function like this, the more important thing is the weight that can detect cage 1.
