Description

Technical Field

[0001] The utility model relates to the technical field of processing of supporting foot pads, in particular to a cutting device for crane supporting foot pads with an auxiliary fixing structure. Background Technique

[0002] The supporting feet are important components of a crane. The supporting feet are mainly used to support the vehicle frame after being connected to the vehicle frame. The ultimate function of the supporting feet is to transfer the force of the whole vehicle to the ground through the supporting feet during the operation of the crane, support the vehicle frame, and ensure the safety and stability of the whole vehicle when the crane is working. Due to the construction of various large-scale facilities, the greater the reaction force on the legs with larger tonnage, which leads to a relatively increased ground contact pressure. In order to increase the ground contact area and reduce the ground contact pressure, the supporting foot pad is placed under the supporting foot plate. When the supporting foot pad is reproduced, a cutting device is needed to cut it.

[0003] After retrieval, it is found that a typical cutting device in the prior art is such as the one with the publication number CN203380415U, a steel plate cutting device, including a cutting table. Above the cutting table, a liftable steel plate pressing block is provided through a frame connected to the cutting table, and a liftable steel plate cutting knife is provided outside the steel plate pressing block. In the utility model, a liftable steel plate pressing block is provided through a frame connected to the cutting table above the cutting table, and a liftable steel plate cutting knife is provided outside the steel plate pressing block. In this way, by placing the steel plate to be cut at a certain position on the cutting table, driving the steel plate pressing block to press the steel plate to be cut on the cutting table through a driving mechanism, and then the steel plate cutting knife runs downward to cut the steel plate from the corresponding position, accurate cutting of the steel plate is realized.

[0004] To sum up, when the existing cutting device is in use, it will first cut the size of the steel plate. The staff will push the steel plate under the cutter, and cut the steel plate by manually pushing the steel plate against the cutter. Because the steel plate is too large and heavy, the operation is difficult. At the same time, relying on manual pushing has potential safety hazards. In view of the above problems, the existing equipment needs to be improved. Content of the Utility Model

The staff will push the steel plate under the cutter, and cut the steel plate by manually pushing the steel plate against the cutter. Because the steel plate is too large and heavy, the operation is difficult. At the same time, relying on manual pushing has potential safety hazards.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A cutting device for crane supporting foot pads with an auxiliary fixing structure, including a frame,

At the same time, the output ends of each group of electric hydraulic cylinders penetrate through the installation frame and are connected to the corresponding electric linear guide rails. The lower end of the electric linear guide rail is connected to an electromagnetic seat through an electric slide seat. A positioning frame is arranged on the other side of the upper end of the frame, and a cutting assembly is arranged at the upper end inside the positioning frame.

[0008] Preferably, the sizes of the plurality of conveying rollers are different, and the size of the conveying rollers arranged between the limiting side plates is longer than the size of the conveying rollers arranged below the positioning frame.

[0012] Compared with the prior art, the beneficial effects of the present utility model are: the cutting device for the crane outrigger pad with an auxiliary fixing structure

[0013] (1) To solve the problem that in the existing cutting device during use, the size of the steel plate is first cut. The staff will push the steel plate to below the cutter and cut it by manually pushing the steel plate against the cutter. Because the steel plate is too large and heavy, the operation is relatively difficult. At the same time, relying on manual pushing has potential safety hazards. In this application, the electric hydraulic cylinder is used to push the electric linear guide rail downward, so that the electromagnetic seat fits with the upper surface of the steel plate. Then, the electric linear guide rail drives the electromagnetic seat and the steel plate to move on the conveying rollers arranged at the upper end of the frame, thereby realizing automatic feeding. The operation is simple and the danger during operation is reduced;

[0014] (2) To solve the problem that the existing cutting device, when in use, does not have an auxiliary fixing structure, resulting in easy deviation when manually pushing the steel plate for cutting, causing unqualified cutting products, wasting materials, and reducing the processing efficiency and quality at the same time. In this application, the limit side plates are used to facilitate the restriction of the area where the steel plate moves, effectively preventing deviation. At the same time, the electric push rod is used to push the auxiliary plate to move, facilitating the restriction of the area of moving and conveying according to the size of the steel plate, improving the accuracy of the conveying direction, and thus improving the cutting quality and efficiency.
