Description

Technical Field

[0001] The invention relates to the technical field of garbage incineration grabbing equipment, in particular to a garbage grabbing bucket cable protection device which has a simple structure, is easy to use, increases the service life of cables, prolongs the operation time of grabbing buckets, and reduces maintenance costs. Background Art

[0002] As we all know, waste incineration is an important way to achieve harmlessness, reduction and resource treatment of waste, which can solve the land waste and pollution problems caused by landfill to the greatest extent. In the current waste incineration process, it is necessary to use a garbage grab to lift the garbage from the garbage pit into the entrance of the waste incinerator, and transport it to the incinerator through the grate for incineration.

[0003] At present, the existing garbage crane is composed of a running trolley, a grab bucket, a lifting cable, and a lifting cable. The running trolley is arranged on a horizontal frame above the garbage pit, and the running trolley is driven and moved by a driving mechanism. There are cable rollers and cable rollers on the running trolley, and the cable rollers and cable rollers are driven by a driving motor. The lifting cable is wound on the cable roller and connected to the grab bucket, and the lifting cable is wound on the cable roller and connected to the junction box on the grab bucket. The cable roller and the cable roller are driven by the driving motor to rotate to realize the rising and falling of the grab bucket. Since the lifting cable rises and falls with the grab bucket, and the cost of the lifting cable is very high, in order to protect the lifting cable, a small cable roller is generally welded on the grab bucket side, and the cable is wound on the small roller with a certain curvature, and connected to the motor junction box on the grab bucket. In order to adapt to the running angle of the grab bucket, the lifting cable generally has a margin between the winding roller and the connecting junction box, so that the cable is in a relaxed and bent state, thereby protecting the lifting cable between the bottom of the roller and the junction box. However, when the operator is operating the grab to feed, dump, and clear the leachate at the bottom of the garbage pool, he is affected by factors such as the field of vision height, restricted space, grab tilt, and the bottom against the wall. Excessive release of the grab will cause the cable above the roller to move downward and bend. After the grab operates again, it often wears and cuts the bent cable, causing grounding and short circuit failures. After multiple cable repairs, the cable length does not reach the safe operating distance of the grab, so a new cable must be replaced, increasing maintenance costs. Summary of the invention

[0004] The purpose of the present invention is to solve the above-mentioned deficiencies in the prior art and to provide a garbage crane grab cable protection device which has a simple structure, is easy to use, increases the service life of the cable, extends the operation time of the grab, and reduces the maintenance cost.

[0013] The present invention is further described below in conjunction with the accompanying drawings:

[0014] As shown in the accompanying drawings, a cable protection device for a garbage grab bucket comprises a cable roller 1, a lifting cable 2 and a grab bucket 3 on a running trolley, a cable roller 4 is arranged on the side of the grab bucket 3, and the cable roller 4 is characterized in that a sleeve 5 is arranged on the cable roller 4 and passes vertically through the middle of the cable roller 4 from top to bottom, and the upper and lower ends of the sleeve 5 are respectively fixedly connected to the cable roller 4, one end of the lifting cable 2 is wound around the cable roller 1, and the other end of the lifting cable 2 passes through the sleeve 5 of the cable roller 4 and is connected to the junction box 6 on the grab bucket 3, and at least three floats 7 arranged in parallel from top to bottom are sleeved on the lifting cable 2 above the sleeve 5 in the cable roller 4, and the float 7 is fixedly connected to the lifting cable 2, and the lower end of the cable sleeved with the float 7 passes through The sleeve 5 is connected to the junction box 6 at the back, and the lifting cable 2 between the lower end of the sleeve 5 and the junction box 6 is in an arc-shaped relaxed state. The outer diameter of the float 7 is larger than the inner diameter of the sleeve 5, ensuring that the float 7 falls on the top of the sleeve 5 and the lifting cable 2 will not move down any further. The float 7 is made of PVC material, which is light and does not affect the function of the cable. The float 7 is made of an elliptical shape, and the elliptical floats 7 are stacked on each other. The floats 7 are fixedly connected to the cables respectively, and the floats 7 are not connected to each other, so that the floats 7 do not pull each other or the cable during the shaking process. The outer layer of the float 7 is coated with a red mark, and the float 7 with a red mark can be clearly observed by the operator, thereby reducing the cable damage rate.

[0015] When the present invention is in use, a sleeve 5 passing through the cable roller 4 is provided on the cable roller 4 on the side of the grab bucket 3, and four floats 7 are installed on the lifting cable 2 passing through the sleeve 5. The four floats 7 are fixedly connected to the lifting cable 2 and are vertically parallel. The outer diameter of the float 7 is larger than the inner diameter of the sleeve 5 to ensure that the float 7 does not move downward. During use, the four floats 7 can protect the cable from being scratched everywhere and can also be used as a reference for the cable to move up and down. When the grab bucket 3 is rising, if the float 7 with a red mark is found to be away from the upper end of the sleeve 5, it can be judged that the cable wound on the cable roller 1 on the trolley has a rewinding or wrong winding phenomenon, and it needs to be lowered in time for observation and processing. When the grab bucket 3 is descending, the float 7 is blocked above the sleeve 5, and the grab bucket The curvature of the lifting cable 2 between the upper junction box 6 and the lower end of the casing 5 remains unchanged. Since the curvature of the cable is guaranteed to remain unchanged, the cable can be guaranteed not to be scratched everywhere. In addition, the lifting cable 2 above the casing 5 is protected by a float 7, and there is a red mark on the float 7. Therefore, the operator can easily observe the operation of the lifting cable 2. The float 7 not only serves as a reminder, but also can protect the cable from being scratched when the lifting cable 2 moves downward too much. The use effect is remarkable, giving the operator an obvious and intuitive visual judgment, and the response is good. The maintenance rate of the grab 3 cable is greatly reduced. Since the cost of the cable is very high, this solution is designed to greatly reduce the cost of repairing and replacing the cable. Therefore, it has very good economic benefits. A small technical improvement has produced a great effect. In the present invention, the cable drum 4 is provided with a sleeve 5 that passes vertically from top to bottom through the middle of the cable drum 4. The upper and lower ends of the sleeve 5 are fixedly connected to the cable drum 4 respectively. One end of the lifting cable 2 is wound around the cable drum 1, and the other end of the lifting cable 2 passes through the sleeve 5 of the cable drum 4 and is connected to the terminal box 6 on the grab 3. The lifting cable 2 above the sleeve 5 in the cable drum 4 is provided with at least three floats 7 arranged in parallel from top to bottom. The float 7 is fixedly connected to the lifting cable 2. The lower end of the cable covered with the float 7 passes through the sleeve 5 and is connected to the terminal box 6. The lifting cable 2 between the lower end of the sleeve 5 and the terminal box 6 is in an arc-shaped relaxed state. The outer diameter of the float 7 is larger than the inner diameter of the casing 5, ensuring that the float 7 falls above the casing 5 and the lifting cable 2 will not move down any further. The float 7 is made of PVC material, which is light and does not affect the function of the cable. The float 7 is set to an elliptical shape, and the elliptical floats 7 are stacked on each other. The floats 7 are fixedly connected to the cables respectively, and the floats 7 are not connected to each other, so that the floats 7 do not pull each other or the cables during the shaking process. The outer layer of the float 7 is coated with a red mark, and the float 7 with a red mark can be clearly observed by the operator, reducing the cable damage rate. It has the advantages of simple structure, easy use, increased cable service life, extended grab 3 operation time, and reduced maintenance costs.
