Description

Technical Field

[0001] The invention relates to the technical field of shaft smearing, in particular to a shaft smearing tool for an inspection shaft. Background Art

[0002] Applying cement mortar tape at the mortar pipe interface is an effective safeguard to prevent leakage at the pipe interface when water is flowing; the main interface types of mortar pipes include flat pipe interfaces, tongue-and-groove pipe interfaces and socket-and-spigot pipe interfaces; among them, the width of the tape at the flat pipe and tongue-and-groove pipe interfaces varies according to the requirements of different pipe diameters; brick-built inspection wells are strictly prohibited in municipal inspection wells, and assembled inspection well shafts are widely used. The gaps in the inspection well shafts after splicing need to be treated with mortar tape.

[0003] However, during construction, workers do not have suitable smearing tools, which can easily lead to uneven width and thickness of the smearing tape after completion, and the mortar loss caused by construction is large, which can easily affect the construction speed and make it difficult to ensure the quality of the project. When manually applying mortar in the gap between the two wellbores, due to the large thickness of the mortar, it is easy to fall off the wellbore after applying the mortar, and the fallen mortar cannot be recycled through the collection component, which may lead to waste of materials. Summary of the invention

[0004] In view of the problems in the prior art, the present invention provides a tool for wiping a belt in an inspection well shaft.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a wellbore wiping tool for an inspection well, comprising an upper wellbore, on which a lower wellbore is clamped and installed; a mounting groove is provided on the lower wellbore; a plurality of hanging mechanisms are clamped and placed on the upper wellbore; a collecting mechanism is fixed on the hanging mechanism; a galvanized material plate is installed on the collecting mechanism; a fixing mechanism is installed on the galvanized material plate; a positioning groove is provided on the galvanized material plate;

[0006] Specifically, the fixing mechanism includes a first protrusion and a rotating rod. The first protrusions are fixedly installed at both ends of one of the galvanized material plates, and the second protrusions are fixedly installed at both ends of the other galvanized material plate. The first protrusion is rotatably connected with a rotating rod, and a slider is threadedly connected to the rotating rod. The second protrusion is fixedly connected with a limiting block, and the limiting block is snap-fitted with the first protrusion. A limiting groove is provided on the first protrusion, and the slider is snap-fitted with the limiting block. The slider is slidably connected with the first protrusion. The limiting block is snap-fitted with the limiting groove, and the ends of the two first protrusions and the second protrusion conflict with each other. The slider is arranged in a "convex" shape.

[0007] Specifically, the diameter of the upper wellbore is equal to the diameter of the lower wellbore, the upper wellbore is clamped and installed in the installation groove, the two galvanized material plates are in contact with the side walls of the upper wellbore and the lower wellbore, and the galvanized material plates are located in the gap between the upper wellbore and the lower wellbore, the diameter of the upper wellbore is smaller than the inner diameter of the galvanized material plate, and the diameter of the top end of the galvanized material plate is larger than the diameter of the bottom end of the galvanized material plate.

[0008] Specifically, the collecting mechanism includes a collecting frame and a positioning rod. The collecting frame is fixedly connected to the galvanized material plate. The bottom end of the collecting frame is threadedly connected to the positioning rod. The positioning rod passes through the inner wall of the supporting frame. The supporting frame is in conflict with the collecting frame. A through groove is provided on the collecting frame. The diameter of the collecting frame is larger than the diameter of the galvanized material plate, and the width of the through groove is larger than the width of the positioning groove.

[0009] Specifically, the hanging mechanism includes a first clamping ring and a second clamping ring, and the first clamping ring and the second clamping ring are fixedly connected to the two support frames respectively, the first clamping ring is fixedly connected to a clamping block, the second clamping ring is provided with a clamping groove, the clamping block and the second clamping ring are clamped and connected, the first clamping ring and the second clamping ring are fixedly installed with a connecting rod, the top of the connecting rod is fixedly connected with a hook, the two groups of the hooks and connecting rods are symmetrically arranged, and the hooks are hung on the top of the upper wellbore.

[0010] The beneficial effects of the present invention are:

[0011] (1) The inspection well shaft wiping tool described in the present invention can make the two galvanized material plates contact each other when the two fixing mechanisms are assembled together, and the galvanized material plates can be fixed by rotating the fixing mechanism using the tool, that is: when installing the wiping tool, the operator can first engage the limit block fixed on the first protrusion into the limit groove provided in the second protrusion. When the limit block is engaged into the inside of the second protrusion, the two ends of the two galvanized material plates can be in a state of contact; then, the tool is used to rotate the rotating rod installed on the first protrusion. The rotating rod rotates inside the first protrusion, which can make the slider threaded on the rotating rod slide in the direction close to the limit block. When the slider is engaged into the inside of the limit block, the slider can limit the limit block, thereby facilitating the fixation of the two galvanized material plates and facilitating the removal of the galvanized material plates from the shaft after the wiping is completed.

[0012] (2) The present invention relates to a tool for smearing a manhole shaft, wherein the collecting mechanism is located at the bottom end of a galvanized plate. When mortar is poured into the galvanized plate, the collecting mechanism can recycle excess mortar, thereby facilitating prevention of waste. That is, after two galvanized plates are assembled together, the collecting frames installed at their bottom ends are also assembled together. The end of the support frame can be fixed to the collecting frame by means of a positioning rod threadedly installed on the collecting frame. The top ends of the two support frames are respectively fixed to a first clamping ring and a second clamping ring, thereby supporting the support frame by means of the first clamping ring and the second clamping ring. Since a positioning groove is provided between the galvanized plate and the upper and lower manhole shafts, the mortar is poured into the positioning groove, thereby performing smearing treatment on the gap between the upper and lower manhole shafts. Furthermore, the diameter of the top end of the galvanized plate is greater than the diameter of its bottom end. After the mortar is poured, a tool is used to rotate on the top end of the galvanized plate, thereby smoothing the top of the poured smearing tape by the tool. While facilitating the limiting of the smearing tape width, it can also prevent the situation in which the smearing tape thickness varies due to manual operation.

[0013] (3) The inspection well shaft wiping tool described in the present invention installs a hanging mechanism on the top of the upper well shaft, so that the hanging mechanism can drive the galvanized material plate to be sleeved on the central part of the gap between the upper well shaft and the lower well shaft, so as to facilitate the width of the well shaft wiping belt to be kept consistent while also supporting the collection mechanism, that is: because the first clamping ring and the second clamping ring are both connected to the support frame, when the two collection frames are spliced ​​together, the clamping block installed on the first clamping ring will be engaged with the clamping groove provided in the second clamping ring, so that the end of the first clamping ring will conflict with the end of the second clamping ring, so that The first clamping ring is spliced ​​with the second clamping ring; when using the smearing tool, the collection frame, the galvanized material plate, the first clamping ring and the second clamping ring are sequentially sleeved on the side walls of the upper shaft and the lower shaft. When the galvanized material plate is located in the gap between the upper shaft and the lower shaft, the hook can be hung on the top of the upper shaft through the connecting rod fixed on the first clamping ring and the second clamping ring. Since the hook is fixedly connected to the connecting rod and the hook is arranged in an L-shaped structure, the gravity exerted on the first clamping ring and the second clamping ring can be supported by the connecting rod, which makes it easy to limit the position of the galvanized material plate when pouring mortar.

[0034] Since the first clamping ring 303 and the second clamping ring 305 are both connected to the support frame 401, when the two collection frames 402 are spliced ​​together, the clamping block 304 installed on the first clamping ring 303 will be engaged with the clamping groove 306 provided in the second clamping ring 305, so that the end of the first clamping ring 303 and the end of the second clamping ring 305 are in conflict, so that the first clamping ring 303 and the second clamping ring 305 can be spliced ​​together; when using the wiping tool, the collection frame 402, the galvanized material plate 5, the first clamping ring 303 and the second clamping ring 305 are sleeved on in turn. The side walls of the upper shaft 1 and the lower shaft 2, when the galvanized material plate 5 is located in the gap between the upper shaft 1 and the lower shaft 2, the hook 301 can be hung on the top of the upper shaft 1 through the connecting rod 302 fixed on the first clamping ring 303 and the second clamping ring 305. Since the hook 301 is fixedly connected to the connecting rod 302, and the hook 301 is arranged in an L-shaped structure, the gravity exerted on the first clamping ring 303 and the second clamping ring 305 can be supported by the connecting rod 302, so as to facilitate the limitation of the position of the galvanized material plate 5 when pouring the mortar.
