Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for electric shovel saddles, in particular to a movable support device for an electric shovel saddle. Background Technique

[0002] An electric shovel is one of the main excavation equipment in ten-million-ton open-pit mines. It has high productivity, high operation rate, and low operation cost, and is a recognized model in the current mining industry. An electric shovel consists of a traveling device, a slewing device, a working device, a lubrication system, and a gas supply system. During the use of an electric shovel, pulling out the dipper stick is a frequently performed maintenance task, such as replacing the dipper stick, pulling out the dipper stick when lowering the boom, etc. When reinstalling the pulled-out dipper stick, the saddle has fallen to the lowest position, and it is very difficult to insert the dipper stick into the saddle opening. Therefore, a support device for the saddle is needed, which can support the saddle at a certain position, prevent it from being at the lowest point, and has a certain inclined opening, so that the dipper stick can be easily inserted into the saddle opening and the reinstallation of the dipper stick can be successfully completed. When using a fixed support, due to wear of the push rod bushing or misalignment of the rack teeth, it will collide with the fixed support when the bucket is at the closest position to the shovel body, causing damage to the support.

[0003] Currently, there is no auxiliary device for an electric shovel saddle to solve the above technical problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a movable support device with reasonable, simple, easy-to-make, low processing cost, convenient operation, safe and reliable, good support performance, and avoiding potential safety hazards caused by mutual collision with the saddle.

[0005] A movable support device for an electric shovel saddle of the utility model includes a first steel plate, the first steel plate is hinged to a second steel plate, a nut is fixedly installed on the bottom surface of the first steel plate; a flat steel bar is clamped on the side wall edge of the first steel plate.

[0006] When the provided flat steel bar and the second steel plate are in use, they can be welded to the side of the boom. When they form a right angle with the first steel plate, this is when the shovel rod of the electric shovel is retracted to the closest position to the electric shovel. At this time, there is a distance of approximately 30 mm between the saddle body and the plate surface of the first steel plate, that is, when the shovel rod is retracted to the closest position to the electric shovel, the edge of the electric shovel saddle body will not contact the first steel plate; after removing the shovel rod, the edge of the saddle body exactly falls on the edge of the first steel plate, giving the saddle body a certain inclination angle, making it easy to insert the shovel rod into the saddle opening when reinstalling the shovel rod, smoothly completing the reinstallation of the shovel rod, with convenient operation, time-saving and labor-saving, safe and reliable in use, and can fully guarantee the safety of the operators; for the provided nut, when it is necessary to use the first steel plate to support the saddle body, the cable rod can be hooked into the nut at the second vehicle platform and gently pulled, then the first steel plate can be rotated, which is easy for the operators to operate; for the provided flat steel bar, when the electric shovel is performing normal excavation operations, the first steel plate rotates upward by 90° around the articulated double-headed bolt. At this time, the first steel plate and the second steel plate form an angle of 180°, that is, they are flat against the side plate of the boom; when the first steel plate and the second steel plate form an angle of 180°, the first steel plate exactly fits into the bent part of the flat steel bar, which can limit the first steel plate, ensuring that the first steel plate and the second steel plate are flat against the side plate of the boom during normal excavation of the electric shovel and will not break away from the restraint of the flat steel bar due to vibration.

[0007] A connecting part is fixedly connected to the lower end surface of the first steel plate, and a hole Ⅰ is provided through the connecting part; a groove is provided on the upper end surface of the second steel plate, and a hole Ⅱ is provided through the upper end surface of the second steel plate; a double-headed bolt is installed through the hole Ⅰ and the hole Ⅱ to hinge the first steel plate and the second steel plate.

[0008] Through the provided connecting part and groove, the first steel plate and the second steel plate can be better engaged, and then through the double-headed bolt passing through the hole Ⅰ and the hole Ⅱ, the first steel plate and the second steel plate can be better hinged. Therefore, the first steel plate can arbitrarily adjust the included angle between the second steel plate and the first steel plate according to the required angle, further support the saddle at a fixed position, prevent the saddle from being at the lowest point, make it easier for the shovel rod to insert into the saddle opening, ensure the operation of completing the reinstallation of the shovel rod, with flexible and practical operation, wide application range, and suitable for various angle adjustments.

[0009] A support plate Ⅰ is fixedly installed on the side wall surface of the first steel plate, and a support plate Ⅱ is fixedly installed on the side wall surface of the steel plate.

[0010] The support plate Ⅰ and the support plate Ⅱ are triangular plates.

[0011] The provided support plate Ⅰ and support plate Ⅱ can play a supporting role for the first steel plate 1, with stable support, safe and reliable. The support plate Ⅰ and support plate Ⅱ are set as triangular plates to ensure that the included angle between the first steel plate after rotating downward and the second steel plate is 90°, thus forming a right-angle brace. When the shovel rod of the electric shovel is removed and the saddle body falls on the edge of the first steel plate, it plays an auxiliary supporting role.

[0012] The flat steel bar comprises a first steel bar, a second steel bar and a third steel bar, wherein the angle between the first steel bar and the second steel bar is 120°; and the angle between the second steel bar and the third steel bar is 120°.

[0013] The flat steel bar is set, when the first steel plate and the steel plate are at 180 degrees during normal excavation operation of the electric shovel, the steel plate is just embedded in the bending part of the flat steel bar, which can limit the first steel plate, ensuring that the first steel plate and the second steel plate are flat against the side plate of the boom during normal excavation of the electric shovel, and will not break away from the constraint of the flat steel bar due to vibration; the first steel bar and the third steel bar are set to facilitate the fixed installation of the entire flat steel bar, the fitting surface is smoother, the installation is more stable, and the safety is improved.
