Description

Technical Field

[0001] This application relates to a drilling tool for the pressure relief cover of a slurry pump. Background Art

[0002] A slurry pump refers to a machine that increases the energy of a solid-liquid mixed medium by means of centrifugal force, and is a device that converts electrical energy into the kinetic energy and potential energy of the medium. It is mainly applicable to: mining, power plants, dredging, metallurgy, chemical industry, building materials, petroleum and other industrial fields. Slurry pumps are generally used to transport materials with a relatively large degree of particle wear, and have extremely high requirements for the hardness of the pressure relief cover. The pressure relief cover mainly refers to a device installed at the inlet or outlet of the pump machine, which reduces the pressure inside the pump machine by changing the pressure difference inside and outside the pump machine, enabling the pump machine to operate more smoothly. When producing and processing the pressure relief cover, a drilling tool is required to fix the pressure relief cover for convenient drilling.

[0003] Although the existing drilling tools have good fixing effects, during drilling, the debris generated by drilling directly falls on the tool and splashes everywhere, making it difficult to clean. Moreover, common pressure relief covers are circular, and a large hole needs to be drilled in the middle of the pressure relief cover and multiple small holes need to be evenly drilled in the outer circle. Due to the extremely high hardness of the pressure relief cover, the pressure relief cover needs to be supported during drilling. Different pressure relief covers have different drilling positions and hole diameters. When fixing different pressure relief covers, the support structure at the bottom will block the drilling position, and different drilling tools need to be replaced, which is rather troublesome to use.

[0004] Therefore, it is desirable to provide a drilling tool for the pressure relief cover of a slurry pump. Utility Model Content

[0005] In this embodiment, a drilling tool for the pressure relief cover of a slurry pump is provided, which solves the problems that the debris generated by drilling directly falls on the tool and splashes everywhere, making it difficult to clean, and that when fixing different pressure relief covers, the bearing structure at the bottom will block the drilling position, and different drilling tools need to be replaced, which is rather troublesome to use.

[0006] According to one aspect of the present application, a drilling tool for the pressure relief cover of a slurry pump is provided, including a base. Multiple groups of support columns are fixed at the bottom of the base. A fixing frame is arranged on the top of the base. Clamping structures are symmetrically arranged on both sides at the top end inside the fixing frame. It is characterized in that the drilling tool for the pressure relief cover of the slurry pump further includes:

[0007] A rotating structure, which is arranged outside the fixing frame;

[0008] A support structure, which is arranged inside the fixing frame.

[0009] Further, a connecting ring is fixed to the bottom of the fixing frame, and the connecting ring is slidably connected in the second chute, and the second chute is arranged on the top of the base.

[0010] Further, the clamping structure includes an electric push rod, an arc-shaped clamping plate and a sliding plate. The electric push rods are symmetrically fixed on the inner walls of the two sides of the top of the fixing frame, and arc-shaped clamping plates are fixed to the ends of the electric push rods, and anti-slip plates are fixed to the inner walls of the arc-shaped clamping plates.

[0011] Further, a decompression cover body is arranged in the middle of the top end of the fixing frame, and both ends of the decompression cover body are abutted against the anti-slip plates.

[0012] Further, the rotating structure includes a motor, a rotating shaft, a gear and a toothed ring. The motor is fixed at one end of the bottom of the base, and the output end of the motor passes through the base and is fixed with the rotating shaft.

[0013] Further, a gear is fixed to the top end of the rotating shaft, and the gear meshes with the toothed ring, and the toothed ring is fixed to the outside of the fixing frame.

[0014] Further, the supporting structure includes a receiving frame, a bearing plate, a mounting frame, a threaded rod, a supporting plate, a slider, a first chute and a mounting plate. The receiving frame is arranged at the bottom of the decompression cover body.

[0015] Further, both ends of the bottom of the receiving frame are clamped to the top of the bearing plate. One end of the bearing plate is fixed to the inner wall of the fixing frame. A mounting frame is fixed to the middle of the inner bottom of the receiving frame, and threaded rods are threadedly connected to the top ends of both side walls of the mounting frame.

[0016] Further, the threaded rod passes through the side wall of the mounting frame and is connected with the supporting plate. The threaded rod is rotatably connected to the side wall of the supporting plate, and the top end of the supporting plate abuts against the bottom of the decompression cover body.

[0017] Further, sliders are fixed to the bottom of the supporting plates, and the sliders are slidably connected in the first chute. The first chute is horizontally arranged on the top of the mounting plate, and one end of the mounting plate is fixed to the outer wall of the mounting frame.

[0018] The advantages of this application are as follows:

[0019] 1. The decompression cover body is fixed in the fixing frame. A receiving frame is installed at the inner bottom of the fixing frame. The debris generated during drilling of the decompression cover body directly falls into the fixing frame. The inner bottom of the fixing frame at the bottom of the electric push rod is inclined, and the debris will slide into the receiving frame for collection. When cleaning the debris, directly take out the receiving frame and pour out the debris in the receiving frame, which is convenient for cleaning.

[0020] 2. By arranging a rotating structure outside the fixed frame, when drilling the outer ring of the pressure reducing cover, the rotating structure drives the fixed frame to rotate, thereby driving the pressure reducing cover body clamped in the fixed frame to rotate, so that the drilling position can be quickly changed and the drilling efficiency is improved.

[0021] 3. By rotating the threaded rod in the support structure, the position of the support plate supporting the pressure reducing cover can be adjusted. When drilling holes in different pressure reducing cover bodies, the support position of the support plate is adjusted so that the support plate avoids the drilling position. It is suitable for different pressure reducing covers. When drilling holes in different pressure reducing covers, there is no need to replace different drilling tooling, which improves the flexibility and practicality of the drilling tooling.

[0034] Please refer to Figures 1-4 As shown, a drilling tooling for the pressure relief cover of a slurry pump includes a base 1. A plurality of support columns 7 are fixedly arranged at the bottom of the base 1. A fixed frame 2 is arranged at the top of the base 1. Clamping structures 3 are symmetrically arranged at both sides of the inner top end of the fixed frame 2. The drilling tooling for the pressure relief cover of the slurry pump further includes:

[0035] A rotating structure 4, and the rotating structure 4 is arranged outside the fixed frame 2;

[0036] A supporting structure 5, and the supporting structure 5 is arranged inside the fixed frame 2.

[0037] A connecting ring 8 is fixedly arranged at the bottom of the fixed frame 2. The connecting ring 8 is slidably connected in a second chute 9, and the second chute 9 is arranged at the top of the base 1.

[0038] The clamping structure 3 includes an electric push rod 301, an arc-shaped clamping plate 302 and a sliding plate. The electric push rods 301 are symmetrically fixedly arranged on the inner top side walls of both sides of the fixed frame 2. Arc-shaped clamping plates 302 are fixedly arranged at the ends of the electric push rods 301. Anti-slip plates 303 are fixedly arranged on the inner walls of the arc-shaped clamping plates 302. The inner bottom of the fixed frame 2 at the bottom of the electric push rods 301 is inclined.

[0039] A pressure relief cover main body 6 is arranged in the middle of the inner top end of the fixed frame 2. Both ends of the pressure relief cover main body 6 are abutted against the anti-slip plates 303.

[0040] The rotating structure 4 includes a motor 401, a rotating shaft 402, a gear 403 and a toothed ring 404. The motor 401 is fixedly arranged at one end of the bottom of the base 1. The output end of the motor 401 passes through the base 1 and is fixedly provided with a rotating shaft 402.

[0041] A gear 403 is fixedly arranged at the top end of the rotating shaft 402. The gear 403 meshes with a toothed ring 404, and the toothed ring 404 is fixedly arranged outside the fixed frame 2.

[0042] In this technical solution, when drilling the outer ring of the pressure relief cover, the rotating structure 4 drives the fixed frame 2 to rotate, so as to drive the pressure relief cover main body 6 clamped in the fixed frame 2 to rotate, which can quickly change the drilling position and improve the drilling efficiency.

[0043] The supporting structure 5 includes a receiving frame 501, a bearing plate 502, a mounting frame 503, a threaded rod 504, a supporting plate 505, a slider 506, a first chute 507 and a mounting plate 508. The receiving frame 501 is arranged at the bottom of the pressure relief cover main body 6.

[0044] The two ends of the bottom of the receiving frame 501 are clamped to the top of the bearing plate 502. One end of the bearing plate 502 is fixed to the inner wall of the fixed frame 2. In the middle of the inner bottom of the receiving frame 501, a mounting frame 503 is fixed. At the top ends of the two side walls of the mounting frame 503, threaded rods 504 are connected.

[0045] In this technical solution, the debris generated during the drilling of the decompression cover body 6 directly falls into the fixed frame 2. The inner bottom of the fixed frame 2 at the bottom of the electric push rod 301 is inclined. The debris will slide into the receiving frame 501 for collection. When cleaning the debris, the receiving frame 501 is directly taken out, and the debris in the receiving frame 501 is poured out, which is convenient for cleaning.

[0046] The threaded rod 504 passes through the side wall of the mounting frame 503 and is connected to a support plate 505. The threaded rod 504 is rotatably connected to the side wall of the support plate 505. The top end of the support plate 505 abuts against the bottom of the decompression cover body 6.

[0047] At the bottom of the support plate 505, sliders 506 are fixed. The sliders 506 are slidably connected in a first chute 507. The first chute 507 is horizontally arranged on the top of a mounting plate 508. One end of the mounting plate 508 is fixed to the outer wall of the mounting frame 503.

[0048] In this technical solution, when drilling different decompression cover bodies 6, the threaded rod 504 in the rotating support structure 5 is rotated to adjust the support position of the support plate 505, so that the support plate 505 avoids the drilling position, which is applicable to different decompression covers. When drilling different decompression covers, there is no need to replace different drilling tooling, which improves the flexibility and practicality of the drilling tooling.

[0049] When this application is in use, the electrical components appearing in the application are externally connected to a power supply and a control device during use. First, adjust the position supported by the support plate 505 according to the position where the decompression cover body 6 needs to be drilled. Rotate the threaded rod 504 in the support structure 5 to move the support plate 505 left and right, so that the support plate 505 avoids the drilling position and does not block the drilling. Then, place the decompression cover body 6 on the top of the installation frame 503, and drive the arc-shaped clamping plate 302 to move towards one side of the decompression cover body 6 through the electric push rod 301, so that the arc-shaped clamping plate 302 clamps and fixes the decompression cover body 6. The anti-slip plate 303 on the arc-shaped clamping plate 302 can enhance the stability of clamping. Then, drill the decompression cover through the drilling device. When drilling the outer ring of the decompression cover, rotate the motor 401 and the gear 403 in the rotating structure 4, and the toothed ring 404 engaged with the gear 403 rotates accordingly. The fixed frame 2 fixed inside the toothed ring 404 also rotates, thereby driving the decompression cover body 6 clamped inside the fixed frame 2 to rotate, which can quickly change the drilling position and improve the drilling efficiency. The debris generated when drilling the decompression cover body 6 directly falls into the fixed frame 2. The bottom inside the fixed frame 2 at the bottom of the electric push rod 301 is inclined, and the debris will slide into the receiving frame 501 for collection. When cleaning the debris, directly take out the receiving frame 501 and pour out the debris inside the receiving frame 501, which is convenient for cleaning.

[0050] The above are only the preferred embodiments of this application and are not used to limit this application. For those skilled in the art, this application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this application shall be included in the protection scope of this application.
