Description

Technical Field

[0001] The present application relates to the technical field of inspection well construction, and in particular to a mortar centrifugal spraying device. Background Art

[0002] Inspection wells are provided for the maintenance of power supply, water supply, sewage discharge, communication, cable TV, gas pipes, street lamp lines, etc. of urban underground infrastructure, and are convenient for installation.

[0003] Currently, after the inspection well is excavated, the inner wall surface of the inspection well needs to be sprayed with mortar. The common method is for two workers to cooperate with each other. One person holds a spraying machine to spray the inner wall surface of the inspection well, and the other person holds the pipe for conveying mortar to the spraying machine, so as to spray the inner wall of the inspection well to enhance its compressive resistance, impermeability, anti-corrosion and other properties, thereby extending the service life of the inspection well.

[0004] However, due to the large reaction force of the spraying machine and the large weight of the pipe for conveying mortar to the sandblasting machine, the spraying efficiency of the inner wall of the inspection well is slow. At the same time, since the sandblasting quality is easily affected during manual construction, the sandblasting quality is reduced. Utility Model Content

[0005] In order to improve the sandblasting quality and efficiency of the inner wall surface of the inspection well, the present application provides a mortar centrifugal spraying device.

[0006] A mortar centrifugal spraying device provided by the present application adopts the following technical solutions:

[0007] A mortar centrifugal spraying device includes a frame body arranged on the inspection well. A sliding plate is slidably arranged on the frame body along the axis direction of the inspection well. A driving component for driving the sliding plate to slide is arranged on the frame body. A spraying mechanism for spraying the side wall of the inspection well is arranged on the sliding plate. The spraying mechanism includes:

[0008] A rotating shaft, which is arranged on the sliding plate and extends into the inspection well;

[0009] A mounting seat, which is rotatably arranged on the rotating shaft;

[0010] A sandblasting machine, which is arranged on the mounting seat and is used for spraying mortar on the side wall of the inspection well;

[0011] A rotating component, which is arranged on the rotating shaft and is used for driving the mounting seat to rotate.

[0012] By adopting the above technical solution, the framework is fixed on the inspection well, and then the rotating assembly drives the mounting seat to rotate on the rotating shaft. Then, the sandblasting machine is started to perform 360-degree sandblasting on the side wall of the inspection well. At the same time, the driving assembly drives the sliding plate to slide downward. By controlling the rotation speed of the mounting seat and the sliding speed of the sliding plate, all-round sandblasting of the side wall of the inspection well is finally realized, improving the sandblasting quality and efficiency of the inner wall surface of the inspection well.

[0013] Furthermore, the rotating assembly includes:

[0014] A gear ring, which is coaxially arranged on the rotating shaft;

[0015] A small gear, which is rotatably arranged on the mounting seat and meshes with the gear ring to drive the mounting seat to rotate on the rotating shaft;

[0016] A driving member, which is arranged on the mounting seat and is used to drive the small gear to rotate.

[0017] By adopting the above technical solution, the driving member drives the small gear to rotate. Through the meshing of the small gear and the gear ring, the mounting seat is driven to rotate on the rotating shaft.

[0018] Furthermore, rollers are arranged on the mounting seat, and the rollers are in rolling contact with the upper surface of the gear ring to support the mounting seat.

[0019] By adopting the above technical solution, one end of the mounting seat away from the rotating shaft is in rolling contact with the gear ring through the rollers, thereby improving the stability of the mounting seat.

[0020] Furthermore, the gear ring is an internal gear ring. On the side of the gear ring away from the rollers, multiple groups of support rods are arranged at intervals. One end of the support rod away from the gear ring is fixedly connected to the rotating shaft to support and fix the gear ring.

[0021] By adopting the above technical solution, multiple groups of support rods are fixed on the rotating shaft to support the bottom of the gear ring, thereby improving the stability of the gear ring. At the same time, the inside of the internal gear ring meshes with the small gear to facilitate driving the mounting seat to rotate.

[0022] Furthermore, the inside of the rotating shaft is hollow, and a feeding assembly for supplying mortar to the sandblasting machine is arranged on the rotating shaft. The feeding assembly includes:

[0023] A feeding pipe, which is arranged inside the rotating shaft and is communicated with an external mortar supply device;

[0024] A rotating pipe joint, which is rotatably arranged at the bottom of the feeding pipe, and the rotating pipe joint is rotatably connected to the rotating shaft;

[0025] A connecting pipe, which is arranged on a sandblasting machine and communicates with a rotary pipe joint to convey the mortar in the feeding pipe into the sandblasting machine.

[0026] By adopting the above technical solution, the feeding pipe is installed in the rotating shaft and rotationally communicates with the connecting pipe through the rotary pipe joint, so that the connecting pipe can always supply mortar to the sandblasting machine when the sandblasting machine rotates with the mounting base.

[0027] Furthermore, a locking assembly for locking the rotating shaft is arranged on the sliding plate. The locking assembly includes:

[0028] A locking block, which slides along the direction close to or away from the sliding plate and presses the rotating shaft against the sliding plate;

[0029] A locking bolt, which passes through the locking block and is locked on the sliding plate;

[0030] A limiting ring, which is slidably arranged on the rotating shaft along the axis direction of the rotating shaft. The limiting ring presses against the locking block and the sliding plate and presses and limits the rotating shaft;

[0031] A fixing bolt, which passes through the limiting ring and fixes the limiting ring on the rotating shaft.

[0032] By adopting the above technical solution, the fixing bolt adjusts the position of the limiting ring on the rotating shaft, and then the locking bolt adjusts the acting force of the locking block on the rotating shaft, so as to facilitate the adjustment of the position of the rotating shaft, thereby facilitating the realization of increasing the sliding distance of the sandblasting machine in the inspection well and finally increasing the spraying distance of the inspection well.

[0033] Furthermore, a protective cover is arranged on the mounting base. The protective cover rotates with the mounting base and protects the rotating assembly.

[0034] By adopting the above technical solution, the protective cover rotates with the mounting base to protect the gear ring, pinion and driving member, prevent sundries from entering the gear ring, pinion and driving member, and ensure the meshing effect between the gear ring and the pinion.

[0035] Furthermore, the frame body is arranged on the inspection well through a positioning assembly. The positioning assembly includes:

[0036] A pressing ring, which presses against the ground and is connected to the frame body;

[0037] Positioning blocks, multiple groups of positioning blocks are arranged in a circumferential array on the pressing ring and press against the side wall of the inspection well. At least three groups of positioning blocks are provided.

[0038] By adopting the above technical solution, the pressing ring is placed on the ground, and multiple groups of positioning blocks press against the side wall of the inspection well, so as to facilitate the rapid and accurate positioning of the position of the frame body.

[0039] In summary, the present application includes at least one of the following beneficial technical effects:

[0040] 1. The frame is quickly positioned on the inspection well through multiple groups of positioning blocks, and then the driving member is started to drive the pinion to rotate, thereby driving the mounting seat to rotate on the rotating shaft. Then, the sandblaster is started to perform 360-degree sandblasting on the side wall of the inspection well. At the same time, the driving assembly drives the sliding plate to slide downward. By controlling the rotation speed of the driving member and the sliding speed of the sliding plate, the all-round sandblasting of the side wall of the inspection well is finally realized, improving the sandblasting quality and efficiency of the inner wall surface of the inspection well.

[0041] 2. The position of the limiting ring on the rotating shaft is adjusted by the fixing bolt, and then the acting force of the locking block on the rotating shaft is adjusted by the locking bolt, so as to facilitate the adjustment of the position of the rotating shaft, thereby facilitating the realization of increasing the sliding distance of the sandblaster in the inspection well and finally increasing the spraying distance of the inspection well.

There are multiple groups of positioning blocks 22, and multiple groups of positioning blocks 22 are circumferentially arrayed on the tightening ring 21 with the axis of the tightening ring 21 as the center line, and multiple groups of positioning blocks 22 all abut against the side wall of the manhole. In order to ensure the positioning effect of the positioning component 2, at least three groups of positioning blocks 22 are provided.

[0052] Reference Figure 1 , the sliding plate 11 is slidably installed on the frame body 1 along the axial direction of the manhole. The driving component 12 includes a lead screw and a motor. The lead screw is rotatably installed on the frame body 1, and the lead screw is threadedly connected to the sliding plate 11. When the lead screw rotates, it drives the sliding plate 11 to slide on the frame body 1; the motor is fixedly installed on the frame body 1 and is used to drive the lead screw to rotate, and finally drive the sliding plate 11 to slide on the frame body 1.

[0053] Reference Figure 1 and Figure 2 , the spraying mechanism 3 is arranged on the sliding plate 11. The spraying mechanism 3 is used for spraying the side wall of the manhole. The spraying mechanism 3 includes a rotating shaft 31, a mounting seat 32 and a sandblasting machine 33. The rotating shaft 31 is fixedly installed on the sliding plate 11, and the rotating shaft 31 extends into the manhole. The axis of the rotating shaft 31 coincides with the axis of the manhole; the mounting seat 32 is rotatably installed on the rotating shaft 31 through a bearing. The bearing is rotatably installed on the outer surface of the rotating shaft 31, and the mounting seat 32 is welded to the outer surface of the bearing. Finally, the mounting seat 32 rotates on the rotating shaft 31; the sandblasting machine 33 is fixedly installed on the mounting seat 32. The sandblasting machine 33 is used for spraying mortar on the side wall of the manhole. By rotating on the rotating shaft 31, the inner side wall of the manhole is sprayed 360 degrees.

[0054] Reference Figure 1 and Figure 2, the spraying mechanism 3 further includes a rotating assembly 4. The rotating assembly 4 is arranged on the rotating shaft 31 and is used to drive the mounting seat 32 to rotate. The rotating assembly 4 includes a toothed ring 41, a pinion 42 and a driving member 43. The toothed ring 41 is coaxially arranged on the rotating shaft 31; in this embodiment, the toothed ring 41 is an internal toothed ring 41; multiple groups of support rods 44 are spaced and installed on the lower surface of the toothed ring 41. One end of the support rod 44 away from the toothed ring 41 is fixedly connected to the rotating shaft 31. The support rods 44 support and fix the toothed ring 41. Through the action of multiple groups of support rods 44, the toothed ring 41 is fixedly installed on the rotating shaft 31.

[0055] Refer to Figure 2 , the pinion 42 is rotatably installed on the mounting seat 32. The pinion 42 meshes with the toothed ring 41. When the pinion 42 rotates, it drives the mounting seat 32 to rotate on the toothed ring 41, and finally makes the mounting seat 32 rotate on the rotating shaft 31; the driving member 43 is fixedly installed on the mounting seat 32 and is used to drive the pinion 42 to rotate; in this embodiment, the driving member 43 is a driving motor.

[0056] Refer to Figure 2 , a roller 321 is fixedly installed on the lower surface of the mounting seat 32. The roller 321 is in rolling contact with the upper surface of the toothed ring 41. The roller 321 supports the mounting seat 32, so as to facilitate the meshing of the pinion 42 with the toothed ring 41 and drive the mounting seat 32 to rotate on the rotating shaft 31. The roller 321 and the support rod 44 are located at opposite ends of the toothed ring 41.

[0057] Refer to Figure 1 and Figure 2 , the inside of the rotating shaft is hollow. A feeding assembly 5 for supplying mortar to the sandblaster 33 is arranged on the rotating shaft. The feeding assembly 5 includes a feeding pipe 51, a rotating pipe joint 52 and a connecting pipe 53. The feeding pipe 51 is fixedly installed inside the rotating shaft 31 and is connected to the equipment for supplying mortar outside.

The connecting pipe 53 realizes rotational connection with the feeding pipe 51 through the rotating pipe joint 52. The connecting pipe 53 bypasses the toothed ring 41 and is fixed on the mounting seat 32. The other end of the connecting pipe 53 away from the rotating pipe joint 52 is internally connected to the sandblaster 33; during use, the mortar in the feeding pipe 51 enters the sandblaster 33 through the rotating pipe joint 52 and the connecting pipe 53. Through the rotational connection between the rotating pipe joint 52 and the feeding pipe 51, when the mounting seat 32 rotates, the connecting pipe 53 rotates with the mounting seat 32 and always supplies mortar to the sandblaster 33; at the same time, a power cord is installed inside the rotating shaft 31, and the power cable of the driving member 43 and the sandblaster 33 is electrically connected to the power cord inside the rotating shaft 31 through a slip ring.

[0058] Refer toFigure 1 and Figure 2 A protective cover is fixedly installed on the mounting base 32. One end of the protective cover is rotatably connected to the rotating shaft 31 through a bearing. The protective cover protects the toothed ring 41, the pinion 42 and the driving member 43, thereby preventing sundries from entering the toothed ring 41, the pinion 42 and the driving member 43, and ensuring the meshing effect between the toothed ring 41 and the pinion 42.

[0059] The working principle of Embodiment 1 of this application is as follows:

[0060] The frame body 1 is quickly positioned on the inspection well through multiple groups of positioning blocks 22, and then the driving member 43 is started to drive the pinion 42 to rotate, thereby driving the mounting base 32 to rotate on the rotating shaft 31. Then the sandblaster 33 is started to perform 360-degree sandblasting on the side wall of the inspection well. At the same time, the driving assembly 12 drives the sliding plate 11 to slide downward. By controlling the rotation speed of the driving member 43 and the sliding speed of the sliding plate 11, a full-range sandblasting treatment of the side wall of the inspection well is finally realized, improving the sandblasting quality and efficiency of the inner wall surface of the inspection well.

[0061] Embodiment 2

[0062] Referring to Figure 3 and Figure 4 This embodiment is different from Embodiment 1 in that a locking assembly 6 for locking the rotating shaft 31 is provided on the sliding plate 11. The locking assembly 6 includes a locking block 61, a locking bolt 62, a limiting ring 63 and a fixing bolt 64. A semi-circular groove for positioning the rotating shaft 31 is formed on the sliding plate 11. The locking block 61 slides along the direction close to or away from the sliding plate 11 and presses the rotating shaft 31 against the sliding plate 11. At the same time, a semi-circular groove matching the groove on the sliding plate 11 is also formed on the locking block 61; the locking bolt 62 passes through the locking block 61 and is locked on the sliding plate 11, thereby pressing the locking block 61 against the sliding plate 11 and pressing and locking the rotating shaft 31.

[0063] Referring to Figure 3 and Figure 4 The limiting ring 63 is slidably mounted on the rotating shaft 31 along the axial direction of the rotating shaft 31. The lower surface of the limiting ring 63 presses against the upper surfaces of the locking block 61 and the sliding plate 11. The fixing bolt 64 passes through the locking block 61 and fixes the limiting ring 63 on the rotating shaft 31, thereby pressing and limiting the rotating shaft 31 to prevent the rotating shaft 31 from sliding downward.

[0064] Referring to Figure 3 and Figure 4, specifically, when the spraying distance of the inspection well is relatively long, after the sliding plate 11 moves down to the maximum distance, the driving assembly 12 drives the sliding plate 11 to rise to the top, then loosens the fixing bolt 64, slides the limiting ring 63 upward by a certain distance, and then tightens the fixing bolt 64 to lock the limiting ring 63 on the rotating shaft 31; then loosens the locking bolt 62, and the locking block 61 moves away from the sliding plate 11, causing the rotating shaft 31 to slide downward until the limiting ring 63 abuts against the upper surfaces of the locking block 61 and the sliding plate 11, and then tightens the locking bolt 62 to press the rotating shaft 31 against the sliding plate 11 through the locking block 61; adjust the position of the sliding plate 11 so that the position of the sandblaster 33 coincides with the previous sandblasting position, and then start the driving assembly 12 to move down again to increase the spraying distance of the inspection well.

[0065] The working principle of Embodiment 2 of the present application is as follows:

[0066] Adjust the position of the limiting ring 63 on the rotating shaft 31 through the fixing bolt 64, and then adjust the acting force of the locking block 61 on the rotating shaft 31 through the locking bolt 62, thereby facilitating the adjustment of the position of the rotating shaft 31, so as to facilitate the realization of increasing the sliding distance of the sandblaster 33 in the inspection well, and finally increasing the spraying distance of the inspection well.

[0067] The above are all the preferred embodiments of the present application. Without limiting the protection scope of the present application accordingly, therefore: all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
