The lifting appliance comprises a lifting appliance body, wherein the lifting appliance body has a lever-shaped structure, one end of the lifting appliance body is provided with a balance weight and a driving motor, the other end of the lifting appliance body is provided with a changeable sleeve, the balance weight is provided with a guide wheel and can slide on the lifting appliance body, and the lifting appliance body is further provided with a limit switch for limiting the slide stroke of the guide wheel. The lifting appliance is simple to operate, and can quickly lift the equipment in place such as a furnace roller of an annealing furnace, a paving pipe and the like on the premise that the safety and the quality are guaranteed, so that the work efficiency can be effectively improved, the use ratio of a lifter can be improved, and the safe operation risk can be reduced.
Description
Technical field
The utility model relates to a kind of equipment hoisting instrument, especially a kind of suspender that is used for equipment such as heating furnace radiant tube or furnace roller.
Background technology
The installation of annealing furnace unit furnace roller divides upper and lower furnace roller two parts usually, is put on the up-down chassis after the bottom furnace roller hangs in special hanger, carries out the assembling of two ends parts then.Then use chain block after the top furnace roller hangs in special hanger it is hung, carry out the assembling of two ends parts then.Orthodox method is to use " shoulder pole " and chain block to accomplish jointly, and is not enough below traditional suspender tool exists: 1, operating process very complicated, and operating process is dangerous also bigger, need carry out sufficient safety precaution; 2, need repeatedly calculate hoisting point position, and join jack and hang flat equipment, operability is complicated, and efficient is low; 3, furnace roller, need repeatedly change hook adjustment when radiant tube passes through fire door, length expends time in.
Summary of the invention
The utility model provides a kind of can carry out quick adjusting suspender and balance of plant, and need not to change hook, and the accessible suspender that passes through fire door improves safety that lifts and the suspender that lifts the band moving counterweight of efficient.
The suspender of band moving counterweight; Include the suspender body; It is characterized in that: described hanging is specially the lever-like structure, and suspender body one end is equipped with counterweight and driving motor, and an other end of suspender body is equipped with the exchangeable sleeve; Wherein said counterweight has guide wheel and can on the suspender body, slide, and the limit switch that is used to limit the guide wheel sliding stroke also is installed on the suspender body.
In such scheme, described suspender body is provided with the stroke screw mandrel, and stroke screw mandrel and guide wheel are that ball screw is in transmission connection, and guide wheel can slide on the stroke screw mandrel, drives counterweight simultaneously and on the stroke screw mandrel, slides.
In such scheme, described limit switch is divided into fourth gear, two end positions about the corresponding counterweight of its position difference, and two control positioies, and counterweight slides into the limit switch place can limited chucking.
The principle of the utility model is that suspender becomes lever-like, and suspender one end connects the exchangeable sleeve, and the other end is a moving counterweight, and suspender has interchangeable sleeve, is applicable to the furnace roller and the radiant tube that connect the various diameters of axle, sleeve and furnace roller or lay to manage and pass through bolted connection; Have moving counterweight, can carry out free leveling; Counterweight drives through movable motor, has worn limit switch above and has carried out position control, is provided with corresponding limit position and working position, and just with leveling quick and precisely, counterweight is through helical screw transmission self-locking.
It is simple to operate that the utility model uses, can guarantee under the prerequisite of safety, quality, fast with the furnace roller of annealing furnace, to lay equipment hoisting such as pipe in place, effectively increases work efficiency, and the degree of utilization of weight-lifting equipment, reduces the safe in operation risk simultaneously.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
The suspender of band moving counterweight as depicted in figs. 1 and 2; Include suspender body 8; Suspender body 8 is the lever-like structure, and suspender body 8 one ends are equipped with counterweight 3 and driving motor 5, and an other end of suspender body 8 is equipped with exchangeable sleeve 2; Wherein said counterweight 3 has to be led 4 and takes turns and can on suspender body 8, slide, and the limit switch 1 that is used to limit guide wheel 4 sliding strokes also is installed on the suspender body 8.
In the present embodiment, described suspender body 8 is provided with stroke screw mandrel 7, and stroke screw mandrel 7 and guide wheel 4 are for ball screw is in transmission connection, and guide wheel 4 can slide on stroke screw mandrel 7, drives counterweight 3 simultaneously and on stroke screw mandrel 7, slides.
In the present embodiment, described limit switch 1 is divided into fourth gear, two end positions about the corresponding counterweight 3 of its position difference, and two control positioies, and counterweight 3 slides into limit switch 1 place can limited chucking.
Concrete operations are that the interface selection exchangeable sleeve 2 according to equipment is installed in exchangeable sleeve 2 on the suspender body 8; The equipment (like furnace roller, radiant tube etc.) of needs liftings is connected with exchangeable sleeve 2, and the arm of force length of limit switch 1 and moving counterweight 3 is installed in adjustment then, and maintenance suspender body 8 levels lift the mounting hole that equipment passes furnace shell just then.
It is as shown in Figure 3 that guide wheel 4 and stroke screw mandrel 7 are connected drive mechanism; Driving motor 5 drives 7 rotations of stroke screw mandrel through chain 6; Ball nut on 4 on stroke screw mandrel 7 and the guide wheel is capable to become the ball screw transmission, and transmission accuracy is high, be easy to self-locking (can accurately locate at end position), can transmit bigger power.Suspender body 8 is provided with four limit positions, and two end positions about the corresponding counterweight 3 of its position difference, and two control positioies can increase and decrease working position according to construction requirement.
The moving counterweight 3 that passes through of the utility model carries out the leveling of suspender; Need not every calculation of equipments hoisting point position; The difference that has remedied because of the distinct device substance causes the drawback of adjustment repeatedly, and assurance equipment can accessiblely once pass through the furnace shell mounting hole, has effectively avoided the interference of jack and furnace shell; Obviously improved the installation effectiveness of equipment, easy to operate, safety.
