Abstract
Description
Technical Field
[0001] The utility model relates to a device capable of preventing the overhead trolley wire from icing and power off, belonging to the technical field of product structure design devices. Background Art
[0002] At present, for the treatment of ice on high-voltage overhead lines, when large lines are iced, a heating resistance line is started for heating and deicing. Such a facility has two problems. One is high investment, and the other is that it is not suitable for equipment like overhead trolley wires because the trolley slide needs to move back and forth along the slide wire and it is impossible to wind the heating resistance line around it. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a device capable of preventing the overhead trolley wire from icing and power off. It is composed of installing a heating device on an ordinary trolley slide, and has the advantages of fast heating, low cost, simple installation, etc. When the overhead trolley wire is iced and the power between the slide and the wire is cut off and it cannot operate, the crane operator only needs to close the heating switch to heat and melt the ice on the slide, so that the overhead trolley can be restored to power and the lifting operation of the overhead trolley can be carried out, thus avoiding the situation where normal lifting cannot be carried out due to the icing and power off of the overhead trolley wire, and solving the above problems existing in the background art.
[0004] The technical solution of the utility model is: a device capable of preventing the overhead trolley wire from icing and power off, comprising a slide, a heating device and a pressing plate. The heating device comprises an aluminum cuboid and heating rods. The heating rods are installed on the aluminum cuboid, and the aluminum cuboid is fixedly connected to the slide through the pressing plate; holes are provided in the width direction of the aluminum cuboid, the heating rods are installed in the holes, and the number and size of the holes match those of the heating rods.
[0005] There are three heating rods and three holes, and the holes are evenly arranged in the width direction of the aluminum cuboid.
[0006] Bolts are welded on the slide, there are two bolts, the distance between them matches the size of the aluminum cuboid, and the bolts are tightly connected to the pressing plate.
[0007] The power of the heating rods is 250W, and the heating rods are connected to a 220V power supply.
[0008] The beneficial effect of the utility model is: it is composed of installing a heating device on an ordinary trolley slide, and has the advantages of fast heating, low cost, simple installation, etc. When the overhead trolley wire is iced and the power between the slide and the wire is cut off and it cannot operate, the crane operator only needs to close the heating switch to heat and melt the ice on the slide, so that the overhead trolley can be restored to power and the lifting operation of the overhead trolley can be carried out, thus avoiding the situation where normal lifting cannot be carried out due to the icing and power off of the overhead trolley wire.

[0012] In order to make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments. Obviously, the described embodiments are only a small part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0013] A device for preventing the overhead crane trolley wire from icing and power off, comprising a slippage 1, a heating device and a pressing plate 4. The heating device comprises an aluminum rectangular cuboid 2 and a heating rod 3. The heating rod 3 is installed on the aluminum rectangular cuboid 2, and the aluminum rectangular cuboid 2 is fixedly connected to the slippage 1 through the pressing plate 4. Holes are provided in the width direction of the aluminum rectangular cuboid 2, and the heating rod 3 is installed in the holes. The number and size of the holes match those of the heating rod 3.
[0014] There are three heating rods 3 and three holes. The holes are evenly arranged in the width direction of the aluminum rectangular cuboid 2.
[0015] Bolts are welded to the slippage 1. There are two bolts, and the distance between them matches the size of the aluminum rectangular cuboid 2. The bolts are tightly connected to the pressing plate 4.
[0016] The power of the heating rod 3 is 250W, and the heating rod 3 is connected to a 220V power supply. Embodiment
[0017] The slippage 1 is a cast iron rectangular cuboid, with a length of 250mm, a width of 200mm, and a thickness of 20mm. The heating device comprises an aluminum rectangular cuboid 2, with a length of 130mm, a width of 90mm, and a thickness of 30mm. In the width direction of the aluminum rectangular cuboid 2, holes with a spacing of 15mm are evenly drilled, and three heating rods 3 with a diameter of φ10×100mm and a power of 250W are installed.
[0018] The manufacturing steps are as follows:
[0019] The first step: melt the aluminum block and pour it into the mold to make a rectangular cuboid with a length of 130mm, a width of 90mm, and a thickness of 30mm.
[0020] The second step: fix the made aluminum rectangular cuboid on the bench drill, and evenly drill 3 holes with a diameter of φ11×105mm at a spacing of 15mm in the width direction.
[0021] Step 3: Install three heating rods of φ10×100mm into the holes and fix them in place.
[0022] Step 4: Weld two φ8 bolts on the upper surface of the sliding block with a spacing of 90mm, place the aluminum cuboid with the heating rods on it, and press it with a pressing plate and tighten the nuts to fix it.
[0023] Step 5: Replace the ordinary sliding blocks on the outdoor overhead crane with the three prepared sliding blocks with heating rods, connect the heating rods to 220V voltage, and it can be normally heated and used after being powered on.
[0024] The utility model has the advantages of fast heating, low cost, simple installation, etc. The overhead crane operator only needs to turn on the heating switch during use to heat and melt ice, and the overhead crane is restored to power to carry out the hoisting operation of the overhead crane, thus avoiding the situation where normal lifting cannot be carried out due to the icing and power failure of the overhead crane trolley wire.
