Description
Technical Field
[0001] The utility model relates to the technical field of maintenance equipment, in particular to a maintenance rack for a jack of a roller bit drill. Background Technique
[0002] The roller bit is one of the most widely used drilling bits. When the roller bit works, the cutting teeth alternately contact the bottom of the well. The rock-breaking torque is small, the contact area between the cutting teeth and the bottom of the well is small, the specific pressure is high, and it is easy to penetrate into the formation; the total length of the working edge is large, so the wear is relatively reduced. The roller bit can adapt to a variety of formations from soft to hard.
[0003] In mining equipment, the roller bit drill of the perforating equipment is essential. The horizontal guarantee of the fuselage when the roller bit drill works is realized by the jacks at the four corners of the roller bit drill; the extension length of the jacks is adjusted to ensure the levelness when the drill works; after the piston seal is worn, the jack will be depressurized and three jacks will bear the force during work, and the support of the drill is unstable; in the existing use, when maintaining the jack, a crane is mostly used to lift the jack down and place it horizontally on the ground. At this time, when disassembling and installing the hydraulic cylinder nut, the hydraulic cylinder needs to be rolled back and forth, and the hydraulic oil flows out, causing waste and environmental pollution. It is not easy to insert the piston rod into the hydraulic cylinder when replacing the seal and installing the piston rod.
[0004] Therefore, there is a need for an auxiliary device for maintaining the jack, which can solve the above technical problems. Content of the Utility Model
[0005] The purpose of the utility model is to provide a maintenance rack for a jack of a roller bit drill with reasonable structural design, low processing and manufacturing cost, easy to operate, safe and reliable, convenient for disassembling and installing the jack bolts, convenient for inserting the piston rod into the hydraulic cylinder, and preventing the hydraulic oil from flowing out and polluting the environment.
[0006] The maintenance rack for a jack of a roller bit drill of the utility model includes a first fixing plate. Four support columns are fixedly installed at the four corners of the first fixing plate. Vertical plates are installed on the opposite sides between the four support columns. First fixing holes are arranged on the surface of the first fixing plate, and third fixing holes are arranged on the side wall surface of the vertical plate.
[0007] On the surface of the first fixing plate, there are first fixing holes, and on the side wall surface of the vertical plate, there are third fixing holes. During use, the jack is lifted by a crane and inserted into the first fixing holes of the maintenance rack. At this time, the positioning hole at the lower part of the jack hydraulic cylinder is exactly located at the opening of the third fixing hole on the vertical plate, that is, the positioning hole at the lower part of the jack hydraulic cylinder and the three third fixing holes arranged on both sides are in a straight line. A steel pipe is inserted into the three holes of the positioning hole at the lower part of the jack hydraulic cylinder and the third fixing holes to form a limit. The jack will not rotate when disassembling and installing the screw of the jack hydraulic cylinder, making it easy to disassemble and install the screw of the jack hydraulic cylinder. The installation operation is more convenient, assisting the operator to complete the maintenance work more efficiently and safely. The operation is safe and reliable; the four support columns provided can firmly support the jack and assist the operator in the maintenance operation.
[0008] A second fixing plate is fixedly installed between the four support columns, and second fixing holes are provided on the surface of the second fixing plate.
[0009] The diameter of the second fixing holes is larger than that of the first fixing holes.
[0010] The first fixing holes provided on the surface of the first fixing plate and the second fixing holes provided on the surface of the second fixing plate are used to fix the jack hydraulic cylinder. When the jack is lifted by a crane and inserted into the maintenance rack, the cylinder body of the jack hydraulic cylinder is located in the first fixing holes, and the bottom of the jack hydraulic cylinder is located in the second fixing plate. Since the diameter of the cylinder body of the jack hydraulic cylinder is large, the diameter of the second fixing holes is large, and the diameter of the bottom of the jack hydraulic cylinder is small, and the diameter of the first fixing holes is small, making the fixation of the entire maintenance rack body more stable, safe and reliable, and facilitating the operator's maintenance.
[0011] The first fixing plate and the second fixing plate are arranged parallel to the horizontal plane.
[0012] The center lines of the first fixing holes and the second fixing holes are located on the same straight line.
[0013] When the jack is inserted into the first fixing holes and the second fixing holes, since the center lines of the first fixing holes and the second fixing holes are located on the same straight line, it is possible to prevent the oil in the jack hydraulic cylinder from leaking out, causing environmental pollution problems. The use is safe and reliable, energy-saving and environmentally friendly.
[0014] The center lines of the third fixing holes arranged on both sides are located on the same straight line.
[0015] The beneficial effects of the present utility model:
[0016] 1) There are first fixing holes on the surface of the first fixing plate, and third fixing holes on the side wall surface of the vertical plate. During use, the jack is lifted by a crane and inserted into the first fixing holes of the maintenance frame. At this time, the positioning hole at the lower part of the jack hydraulic cylinder is exactly located at the opening of the third fixing hole of the vertical plate, that is, the positioning hole at the lower part of the jack hydraulic cylinder and the three third fixing holes on both sides are in a straight line. A steel pipe is inserted into the three holes of the positioning hole at the lower part of the jack hydraulic cylinder and the third fixing holes to form a limit, so that the jack will not rotate when disassembling and installing the screw rod of the jack hydraulic cylinder, making it easy to disassemble and install the screw rod of the jack hydraulic cylinder, and the installation operation is more convenient, assisting the operator to complete the maintenance work more efficiently and safely, and the operation is safe and reliable; the four support columns provided can firmly support the jack and assist the operator in the maintenance operation.
[0017] 2) The first fixing holes on the surface of the first fixing plate and the second fixing holes on the surface of the second fixing plate are used to fix the jack hydraulic cylinder. When the jack is lifted by a crane and inserted into the maintenance frame, the cylinder body of the jack hydraulic cylinder is located in the first fixing holes, and the bottom of the jack hydraulic cylinder is located in the second fixing plate. Since the diameter of the cylinder body of the jack hydraulic cylinder is large, the diameter of the second fixing holes is large, the diameter of the bottom of the jack hydraulic cylinder is small, and the diameter of the first fixing holes is small, making the fixation of the entire maintenance frame more stable, safe and reliable, and facilitating the operator's maintenance.
[0018] 3) When the jack is inserted into the first fixing holes and the second fixing holes, since the center lines of the first fixing holes and the second fixing holes are on the same straight line, it can prevent the oil in the jack hydraulic cylinder from leaking out and causing environmental pollution problems. It is safe and reliable in use, energy-saving and environment-friendly.
[0019] 4) The device has a reasonable structural design, low processing and manufacturing cost, easy to operate, safe and reliable, convenient for disassembling and installing the jack bolts, convenient for inserting the piston rod into the hydraulic cylinder, preventing the hydraulic oil from flowing out and polluting the environment. At present, it has been put into production and use, and the use effect is good. BRIEF DESCRIPTION OF THE DRAWINGS
