Description
Technical Field
The utility model relates to a special tool for installing screws on a brake wheel.
Background
The bridge and portal crane are used as movable special equipment, and brakes are arranged on the lifting mechanism and the large and small car running mechanism of the bridge and portal crane, and are important safety components of the bridge and portal crane. Because the space on the bridge and the portal crane is narrow, the layout of each equipment part is very compact, and the distance between each equipment and the parts is very small, so that the replacement and maintenance difficulties of the equipment parts on the bridge and the portal crane are high. Particularly, the brake wheels on the motors of the lifting mechanism and the running mechanism of the gantry crane are very close to the motor fan cover, when the motors are replaced, the connecting screws on the brake wheels are very inconvenient to assemble and disassemble, the hands are not plugged into the space of the inner head of the brake disc, the screw holes are not plugged into the inner head of the brake disc by clamping the screws between the two fingers, so that the operation difficulty of replacing the motors is increased, and the operation time of replacing the motors is prolonged. Because many bridge and portal cranes have high operation rate, heavy production tasks and short equipment maintenance time given by a producer, a special method or special tool is needed to be adopted when the bridge and portal cranes replace the motor, and the connecting bolts on the brake wheel are installed (penetrated) into screw holes of the brake wheel at the highest speed, so that the on-time completion of motor replacement operation is ensured. The existing installation (threading) method of the brake wheel connecting screw for operators in bridge and portal crane maintenance departments is to screw 5-6 copper wires with enough length into a strand (2 wires are needed), thread one copper wire into the brake wheel from a first screw hole on the brake wheel, bind the rope head coming out of the rear end of the brake wheel on a screw fastener of the connecting screw, bind the other copper wire on a hexagon head of the screw, respectively grasp two ends of the 2 copper wires by two hands of the operators, pull the copper wire outside the screw hole of the brake wheel outwards, send the connecting screw to the inner head of a brake disc, shake the copper wire up and down and left and right after the screw head is close to the screw hole of the brake disc, and then continuously pull outwards, pull the screw head from the screw hole of the brake disc, thereby completing the installation (threading) of the first screw; sequentially installing other brake wheel connecting bolts according to the same steps and methods; this method of mounting the connecting screw on the brake disc is very cumbersome and particularly delays. Although the task of installing the connecting screw on the brake disc can be completed, the requirement of completing the operation of replacing the motor according to the time node cannot be met; therefore, the method for installing (penetrating) the connecting screw on the brake wheel has great defects, needs to be optimized, and needs to find out a more proper method for installing (penetrating) the connecting screw on the brake disc or design a special tool for installing (penetrating) the connecting screw on the brake disc.
Disclosure of Invention
The utility model aims to provide a special tool for installing screws on brake wheels, which can solve the technical problem of installing connecting screws on motor brake wheels of bridge and gantry cranes.
The technical scheme includes that the special tool for installing screws on the brake wheel comprises a main pipe body and an auxiliary pipe body, wherein the auxiliary pipe body is horizontally fixedly connected to the lower end of the main pipe body, a pushing spring is sleeved in the auxiliary pipe body, an inner hexagon sleeve is formed in the right opening end of the auxiliary pipe body, the left side end of the auxiliary pipe body is closed, an opening is formed in the right side part of the lower end of the main pipe body at the top surface of the auxiliary pipe body, an operating rod is sleeved in the main pipe body, the lower part of the operating rod is horizontally bent from the opening of the lower end of the main pipe body and extends out to be tightly attached to the top surface of the auxiliary pipe body, the right free end of the operating rod is downwards bent to form a clamping hook, a notch is formed in the back surface of the upper part of the main pipe body, a push rod is arranged in the back surface of the upper part of the operating rod, the push rod extends backwards from the notch, the top end of the main pipe body is closed, a compression spring is arranged in the top end of the main pipe body, and the lower end of the compression spring is propped against the top end of the operating rod; the outer side part of the upper end of the main pipe body is also provided with a holding handle.
When the auxiliary pipe body with the screw is used, firstly, the push rod is pressed into the inner hexagon sleeve at the right side end of the auxiliary pipe body, then the push rod is loosened, at the moment, the pushing spring in the inner hexagon sleeve contracts (stores energy) and props against the rear of the hexagon head of the connecting bolt, under the thrust of the compression spring in the main pipe body, the hexagon head of the connecting bolt is tightly clamped by the clamping hook at the right side end of the operating rod, secondly, the holding handle is held by hands, the side of the auxiliary pipe body with the screw is plugged into a gap between the rear end of the driving wheel and the motor fan cover, and then the main pipe body and the auxiliary pipe body are synchronously rotated by 90 degrees, so that the screw head is aligned to the screw hole of the braking wheel to press the push rod, and at the moment, the pushing spring in the inner hexagon sleeve ejects (releases energy) to push the connecting screw into the screw hole of the braking wheel. Other connecting bolts are sequentially installed (penetrated) into the screw holes of the brake wheel according to the steps and the method.
When designing the special tool for installing the screw on the brake wheel, in order to ensure that the special tool accurately penetrates the connecting bolt into the screw hole of the brake wheel, the special tool for installing the screw on the brake wheel with corresponding dimensions (sizes) is designed and manufactured according to the size of the brake wheel and the size of a gap between the motor fan cover and the rear end of the brake wheel, so that the dimensions of parts formed by the special tools for installing the screw on the brake wheels with different sizes are also changed. The special tool for installing the screws on the brake wheels can rapidly install (penetrate) the connecting bolts to the screw holes of the brake wheels through the steps, the installation (penetrating) process of each connecting screw only needs 20-30 seconds, labor and time are saved, and working efficiency is greatly improved.
