Description

Technical Field

[0001] The present invention relates to the field of pole processing and manufacturing, and specifically to a demoulding device for a suspended pole mold. Background Art

[0002] Poles are core components used to support overhead lines in infrastructure such as power and communication. They mainly bear the function of supporting equipment such as conductors and crossarms. Common materials include wood, concrete, steel, etc. Electric power is transmitted over long distances by erecting conductors, and they are widely distributed in urban, rural, and wild environments. Currently, the mainstream poles are mainly made of concrete, whose durability and load-bearing capacity are significantly better than traditional wooden and iron poles, making it the first choice for modern power grid construction.

[0003] The production process of concrete poles includes processes such as steel bar processing, concrete batching, centrifugal forming, and steam curing. The mold and its turnover rate affect the concrete production efficiency. Concrete poles are formed by the centrifugal method, which is one of the manufacturing processes for poles. Reinforcing bars or steel wire skeletons are arranged inside the poles to enhance crack resistance, and the circular cross-section can optimize the stress distribution. In the centrifugal forming process, the pole molds used are generally custom-made steel molds. During the production process of poles, the custom-made steel molds adopt an internal and external double-spliced steel film. After the poles are formed in the custom-made steel molds, they also need to be placed and cured for a long time before demoulding, resulting in problems such as slow production efficiency and occupation of site.

Detailed Embodiments

[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments.

[0015] Embodiment 1 As Figures 1 to 6As shown in the figure, there is a demoulding device for a suspended pole mould. This demoulding device is used to facilitate the rapid casting and forming of poles and save the demoulding time. In terms of structural design, the demoulding device includes two outer model hoops 1 that can be spliced and connected by bolts. A number of roller guides 11 are respectively connected to the outer walls of the outer model hoops 1. Rail wheels corresponding to the roller guides 11 are respectively arranged on both sides of the outer model hoops 1. The rail wheels are respectively adapted to the roller guides 11. The rail wheels on the same side are connected to the output end of the driving motor through a rotating shaft, and the rail wheels are driven to rotate by the driving motor. The rail wheels arranged on both sides limit the rotation of the spliced outer model hoops 1 and the pole concrete poured inside the outer model hoops 1. Through the centrifugal action, "centrifugal vibration" is carried out on the pole concrete poured inside the outer model hoops 1, so as to ensure the quality of the poles poured inside the outer model hoops 1.

[0016] At the same time, an inflatable core mould 2 is arranged inside the spliced outer model hoops 1. The gap between the inflatable core mould 2 and the outer model hoops 1 is used to place the pole steel skeleton and is filled with concrete to be cast into the shape of a pole. With such a design, the inflatable core mould 2 acts as the "inner mould of the pole", and the spliced outer model hoops 1 act as the "outer mould of the pole". The gap between the two is used to place the pole steel skeleton and pour concrete, so that it is formed into a "concrete pole".

[0017] Moreover, on both sides of the through-hole cavity of the inflatable core mould 2, movable support mechanisms for stably supporting the inflatable core mould 2 are respectively arranged. By the "expansion" of the arranged movable support mechanisms, the inner wall of the inflatable core mould 2 is stably supported, ensuring the stability of the inflatable core mould 2 acting as the inner mould. Thus, when "centrifugal vibration" is carried out, it is ensured that the inflatable core mould 2 does not deform, so as not to affect the quality of the concrete pole after forming. And when the pole after casting and forming is cured for a certain period of time, by adjusting and controlling the movable support mechanisms, "folding and shrinking" can be realized, so as to facilitate the removal of the inflatable core mould 2 acting as the inner mould, improve the turnover rate of the mould, save time in this way, and reduce the time for the pole to occupy the site.

[0018] Embodiment 2 Based on Embodiment 1, both of the two movable support mechanisms are provided with movable adjustment structures, and at least three movable adjustment structures are provided. Among them, each movable adjustment structure includes a first movable seat 31 and a second movable seat 32 that are movably arranged in the through-hole cavity of the inflatable core mould 2. The first movable seat 31 and the second movable seat 32 are respectively movably penetrated through a movable adjustment lead screw 3. The first movable seat 31 and the second movable seat 32 are provided with opposite threads, and the first movable seat 31 and the second movable seat 32 can move relatively by driving the movable adjustment lead screw 3.

[0019] Meanwhile, a number of arc-shaped support hoops 4 are provided on the outer walls of the first movable seat 31 and the second movable seat 32. The support hoops 4 are all connected to the first movable seat 31 and the second movable seat 32 through movable connection structures; the support hoops 4 are used to be movably arranged in the through cavity of the inflatable core mold 2, and the support hoops 4 are driven to move and expand to support on the inner wall of the inflatable core mold 2 through the movable connection structures, so as to stably support the inflatable core mold 2.

[0020] In the embodiment, the two movable adjustment structures are respectively arranged in the hollow cavities at both ends of the inflatable core mold 2, and the movable adjustment structures at both ends are respectively connected to the spliced outer model hoop 1 through bolts; then, by adjusting and controlling the movement of the movable adjustment screw 3 of the movable adjustment structure, the movable adjustment structure is driven to move, so that the support hoops 4 connected to each other are driven to move and expand in the inflatable core mold 2, and are used to support on the inner wall of the inflatable core mold 2, so as to stably support the inflatable core mold 2, thereby avoiding the deformation and movement of the inflatable core mold 2 and affecting the quality of the cast pole. It should be noted here that at least three movable adjustment structures are arranged on the movable adjustment screw 3, so that the number of movable adjustment structures can be appropriately increased according to the length of the pole designed and constructed, so as to ensure that when the movable adjustment screw 3 is rotated and adjusted, there is enough power to drive the support hoop 4 to move and expand and enough supporting force to stably support the inflatable core mold 2.

[0021] Embodiment 3 Furthermore, the movable connection structure includes a movable adjustment rod 33 and a movable hinge rod 34; one end of the movable adjustment rod 33 is hinged to the first movable seat 31 through a pin shaft, the other end of the movable adjustment rod 33 is hinged to the support hoop 4 through a pin shaft, and the movable adjustment rod 33 is obliquely arranged; one end of the movable hinge rod 34 is hinged to the middle of the movable adjustment rod 33 through a pin shaft, and the other end of the movable hinge rod 34 is hinged to the second movable seat 32 through a pin shaft.

[0022] Meanwhile, a support and stability flange 5 is arranged at one end of the movable adjustment screw 3 close to the end of the inflatable core mold 2; one end of the movable adjustment screw 3 close to the support and stability flange 5 passes through the support and stability flange 5 rotatably through a bearing, and the support and stability flange 5 is used to be connected to the outer model hoop 1; the specific connection method can be: the ends of the outer model hoop 1 are respectively connected with outer film flanges 12 through bolts, and the outer film flanges 12 and the support and stability flange 5 are detachably connected through bolts. And, the end of the movable adjustment screw 3 far from the support and stability flange 5 is used to be connected to the output end of the screw machine that drives the movable adjustment screw 3 to rotate and move.

[0023] In an embodiment, by separately controlling the start of two externally connected lead screw machines, the lead screw machines drive the movable adjusting lead screw 3 to rotate around the support and stability flange 5 under the movable limit effect of the support and stability flange 5, driving the first movable seat 31 and the second movable seat 32 sleeved on the movable adjusting lead screw 3 to move relatively closer (since the threads provided on the first movable seat 31 and the second movable seat 32 are opposite, that is, under the driving effect of the movable rotation of the movable adjusting lead screw 3, the first movable seat 31 and the second movable seat 32 can move relatively closer). To ensure that the first movable seat 31 and the second movable seat 32 can move relatively closer, several movable guide rods 51 are provided at one end of the support and stability flange 5 close to the through cavity of the inflatable core mold 2 (that is, these several movable guide rods are used to be arranged in the through cavity of the inflatable core mold 2); one end of the movable guide rod 51 is used to be fixedly connected to the support and stability flange 5, and the other end of the movable guide rod 51 is used to pass through the first movable seat 31 and the second movable seat 32 of the movable adjusting structure; thus, when driving the movable adjusting lead screw 3 to rotate, the first movable seat 31 and the second movable seat 32 are under the movable guiding and limiting effect of the provided movable guide rods 51 and because the "internal threads" of the first movable seat 31 and the second movable seat 32 are opposite, that is, one is positively adapted and the other is reversely adapted to the thread on the provided movable adjusting lead screw 3; furthermore, under the movable effect of the rotation of the movable adjusting lead screw 3, the first movable seat 31 and the second movable seat 32 move towards each other on the movable adjusting lead screw 3, driving the movable adjusting rod 33 and the movable hinge rod 34 to move, and finally driving the provided support hoop 4 to support and abut against the inner wall of the inflatable core mold 2, so as to support and stabilize the inflatable core mold 2.

[0024] Furthermore, in an embodiment, sliding guide rails are respectively connected to the outer wall of the outer model hoop 1, and a guiding sliding seat corresponding to the sliding guide rail is connected to the inner diameter of the roller guide rail 11. The guiding sliding seat is provided with a sliding groove, the sliding groove is slidably adapted to the sliding guide rail, and the guiding sliding seat and the sliding guide rail are connected and limited by bolts. In this way, the guiding sliding seat provided on the roller guide rail 11 can use the connection part of the splicing seam of the two outer model hoops 1 as the "sliding guide rail". After sliding and limiting the sliding groove opened on the guiding sliding seat on the "sliding guide rail" to a suitable position, the guiding sliding seat and the "sliding guide rail" are connected by bolts; this can not only be used to limit and connect the two outer model hoops 1 to make their connection more firm and reduce the probability of "mold explosion"; but also can reduce the joint seam between the outer model hoop 1 and the roller guide rail 11 and ensure the quality of the poles constructed.

[0025] Through this demoulding device, not only can the quality of the poles processed and manufactured be ensured and their service life be increased; moreover, through this demoulding device, the production efficiency of the poles can also be improved, and the processing cost and site can be saved.
