Description

Technical Field

[0001] The utility model relates to the technical field of detection well casting moulds, in particular to an easy-to-demold detection well casting mould. Background Art

[0002] Inspection wells, also known as inspection wells, are indispensable buildings in municipal engineering construction. Inspection wells play a huge role in the installation and maintenance of urban underground power supply, water supply and drainage, communication and gas lines. For example, in the summer in the south, the amount of rain increases, and various debris will enter the sewer pipes with the water flow. Once there are too many debris, the underground drainage pipes will be blocked, resulting in water accumulation on the road. Workers need to go down to check the drainage system. At this time, the staff enters the municipal pipelines through the inspection wells set up in the municipal pipelines to repair and inspect the pipelines.

[0003] At present, most detection wells are concrete castings, which are mainly cast and formed using detection well casting molds. The existing detection well casting mold is mainly composed of a base frame, an outer mold barrel, an inner mold core and an annular plate. The bottom end of the outer mold barrel is fixed to the top of the base frame; the inner mold core is located in the outer mold barrel and placed on the base frame; the annular plate is arranged along the circumference of the outer mold barrel, and is placed on the base frame corresponding to the outer mold barrel and the inner mold core, and the detection well casting area is formed between the outer mold barrel, the inner mold core and the annular plate. In practical applications, the above structure can directly cast concrete mortar into the detection well casting area, which can quickly form the detection well and improve the detection well casting efficiency. However, the outer mold barrel, the inner mold core and the annular plate are fixed structures and cannot be moved. After the concrete mortar is solidified and formed in the detection well casting area, it cannot be taken out normally.

[0004] In order to solve the above technical problems, a variety of splicable outer mold barrels have been launched on the market. Taking advantage of the splicable outer mold barrel, after the detection well is cast and formed, the spliced ​​parts are disassembled and the outer mold barrel is disassembled to improve the efficiency of removing the detection well. However, the outer mold barrel is too large and too heavy, which makes it difficult to disassemble and assemble, and the disassembly and assembly efficiency is too low, which cannot meet the industrial production efficiency.

[0005] Therefore, how to design a detection well casting mold that is simple to operate and easy to demould is a problem that technical personnel in this field urgently need to solve. Utility Model Content

[0006] The utility model provides a detection well casting mould which is easy to demould, and solves the technical problem that the detection well cast in the existing detection well casting mould is difficult to take out.

[0007] The utility model solves the above-mentioned technical problem with the following technical solution: a mold for casting a detection well that is easy to demold, comprising a base frame, an outer mold barrel, an inner mold core and an annular plate, wherein the bottom end of the outer mold barrel is fixed to the top end of the base frame; the inner mold core is located in the outer mold barrel and is placed on the base frame; the annular plate is arranged along the circumference of the outer mold barrel and is placed on the base frame corresponding to the gap between the inner mold core and the outer mold barrel, and the gap between the outer mold barrel, the inner mold core and the annular plate is the casting area of ​​the detection well; the inner mold core comprises: a fixed core plate, a movable core plate, a top core plate and a driving opening and closing component,

[0008] The fixed core plate and the movable core plate are both arc-shaped structures and their arc lines are parallel to the circumference of the outer mold tube. The fixed core plate and the movable core plate are relatively arranged in the outer mold tube and can be spliced ​​into a cylindrical structure. The bottom end of the fixed core plate is fixed to the top end of the base frame; the annular plate is sleeved on the outer circumference of the cylindrical structure; the top core plate is fixed to the top end of the fixed core plate; the casting area of ​​the detection well is the gap between the outer mold tube, the cylindrical structure, the top core plate and the annular plate; the driving opening and closing assembly is located in the cylindrical structure and its fixed part is fixed to the top end of the base frame, and the driving part of the driving opening and closing assembly reciprocates radially along the cylindrical structure; the inner side wall of the movable core plate is hinged on the driving part and reciprocates radially along the cylindrical structure to separate the movable core plate from the detection well in the casting area of ​​the detection well.

[0009] The beneficial effects of the utility model are: breaking through the design constraints of the traditional detection well casting mold that moves the outer mold cylinder to accelerate demolding, and utilizing a fixed core plate, a movable core plate, a top core plate and a driving opening and closing assembly to form an inner mold core of a splicing structure. Since the fixed core plate and the movable core plate can be spliced ​​into a cylindrical structure, and since the driving part of the driving opening and closing assembly in the cylindrical structure is fixed on the inner wall of the movable core plate, when the detection well cast in the detection well casting area needs to be taken out, the driving part of the driving opening and closing assembly can be used to push the movable core plate to move radially along the cylindrical structure, thereby accelerating the separation speed of the movable core plate from the detection well and improving the removal efficiency of the detection well.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, the driving opening and closing assembly includes a support frame, a driving rotating rod, a lifting rod and a linkage, the support frame being the fixed part of the driving opening and closing assembly, the support frame being placed in the cylindrical structure along the axis of the cylindrical structure and having its bottom end fixed to the top end of the base frame; the driving rotating rod being rotatably connected in the base frame along a direction perpendicular to the axis of the cylindrical structure and having one end movably extending out of the base frame; the lifting rod sliding in the support frame along the axis of the cylindrical structure and having its bottom end hinged to the middle part of the driving rotating rod, so as to drive the lifting rod to reciprocate along the axis of the cylindrical structure with the rotation of the driving rotating rod; the linkage is the driving part of the driving opening and closing assembly, one end of the linkage is hinged to the outer wall of the lifting rod and the other end is hinged to the inner wall of the moving core plate, so as to link the moving core plate to reciprocate radially along the cylindrical structure with the lifting and lowering of the lifting rod.

[0012] The above-mentioned further beneficial effect is: by rotating the driving rotating rod, since the lifting rod slides on the support frame along the height direction of the support frame and its bottom end is hinged to the middle part of the driving rotating rod, the lifting rod can be driven to move up and down while the driving rotating rod rotates; at the same time, since one end of the linkage is hinged to the outer wall of the lifting rod and the other end is hinged to the inner wall of the moving core plate, the moving core plate can be synchronously linked to move back and forth along the radial direction of the cylindrical structure.

[0013] Furthermore, the driving opening and closing assembly also includes a rocker, one end of which is vertically fixed to the protruding end of the driving rotating rod that movably extends out of the base frame.

[0014] A further beneficial effect of adopting the above method is that by using the rocker to rock the rotating rod, the driving method of the rotating rod can be simplified and the splicing efficiency of the cylindrical structure can be improved.

[0015] Furthermore, the linkage member includes a linkage rod and a linkage plate, one end of the linkage rod is hinged to the outer side wall of the lifting rod; one end of the linkage plate is hinged to the other end of the linkage rod; the inner side wall of the movable core plate is hinged to the other end of the linkage plate.

[0016] Furthermore, the linkage rod and the linkage plate are multiple and arranged at intervals along the height direction of the support frame.

[0017] Furthermore, it also includes a guide assembly, which includes two guide support frames, two guide mounting frames and two guide slide rods. The linkage plate is provided with two symmetrically arranged guide slide holes, and the two guide slide holes extend along the circumference of the outer mold cylinder; the two guide support frames are fixed on the inner side walls of the fixed core plate at opposite sides of the movable core plate; the two guide mounting frames are symmetrically fixed on the two guide support frames; the two guide slide rods are respectively fixed on the two guide mounting frames and slide in the two guide slide holes respectively along the circumference of the outer mold cylinder.

[0018] The further beneficial effect of adopting the above method is: by utilizing the guide slide rod to slide axially along the outer mold cylinder in the guide slide hole, the moving direction of the movable core plate can be guided, the shaking of the movable core plate during movement can be avoided, and the stability of the movement of the movable core plate can be improved.

[0019] Furthermore, the guide assembly also includes a limiting strip plate, which is located above the guide mounting frame and the linkage plate and fixed on the two guide support frames, and the limiting strip plate can contact the movable core plate.

[0020] A further beneficial effect of adopting the above method is that by utilizing the contact between the limiting strip plate and the movable core plate, the moving distance of the movable core plate can be shortened and the reset speed of the movable core plate can be increased.

[0021] Furthermore, it also includes a rotating wheel, which is multiple and rotated at intervals and connected to the bottom end of the movable core plate, and the multiple rotating wheels all rotate at the top end of the base frame.
