Description

Technical Field

[0001] The present application relates to the technical field of concrete pouring on the surface of ductile iron jacking pipes, and more specifically, to an auxiliary pouring pool for concrete pouring on the surface of ductile iron jacking pipes. Background Art

[0002] Concrete underground pipelines are pipelines laid underground for the transportation of liquids, gases or lines. The production of concrete underground pipelines usually involves placing a concrete casting formwork on the outside of a welded steel cage, then pouring concrete into the concrete casting formwork, and then removing the formwork after the concrete solidifies, thereby preparing the concrete underground pipeline.

[0003] The document with the prior art announcement number CN213290773U provides a ductile iron jacking pipe surface concrete auxiliary pouring pool. When preparing a concrete underground pipeline, the device first welds the steel cage on the outer end of the ductile iron jacking pipe. After the welding of the steel cage is completed, a concrete pouring template is set on the outer end of the steel cage. Then, the concrete pouring template with the ductile iron jacking pipe inside is placed vertically on a vibration plate and limited by a limit device. After the limiting is completed, the vibration motor is turned on and the concrete filling operation is carried out at the same time until the concrete filling is completed; after the concrete is solidified and formed, the demoulding process is carried out, and then the spray water pipe is turned on for spray curing operation. After the spray curing is completed, the formed pipeline is hoisted to the designated position.

[0004] Although the above-mentioned prior art scheme can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: after pouring concrete into the concrete pouring formwork with a ductile iron jacking pipe inside, the above-mentioned prior art can limit the concrete pouring formwork through a limiting device, but it is still unable to achieve the reinforcement and support treatment of the concrete pouring formwork, resulting in that after the concrete is poured into the concrete pouring formwork, the inner wall of the formwork is easily squeezed by the concrete and the formwork runs and expands, making it difficult to ensure the product quality of the concrete underground pipeline and requiring secondary rework, which not only wastes the time and physical strength of the operating workers, but also prolongs the production cycle of the concrete underground pipeline, resulting in a decrease in the production efficiency of the concrete underground pipeline. Summary of the invention

[0005] Technical problem to be solved: The purpose of this application is to provide a ductile iron top pipe surface concrete auxiliary pouring pool, which solves the technical problems raised in the above-mentioned background technology.

[0006] Technical solution: The technical solution of the present application provides an auxiliary pouring pool for concrete on the surface of a ductile iron jacking pipe, including a pouring pool and a support platform connected to the bottom end of the inner cavity of the pouring pool; a concrete pouring template with a ductile iron jacking pipe inside is placed on the top of the support platform, and two brackets are symmetrically connected to the left and right of the support platform, each bracket is connected to a hydraulic cylinder, and the opposite ends of the two hydraulic cylinders are connected to clamping seats, and the front and rear ends of the clamping seats are connected to side wing seats; a number of tensioning screws are connected from top to bottom to the side wing seats connected to the two ends of one of the clamping seats, and the other end of the tensioning screw passes through the other clamping seat and is threadedly connected to a nut.

[0007] As an optional scheme of the technical scheme of the present application document, an end extension rod is also connected to the end of the tensioning screw away from the side wing seat to which it is connected; a limiting sleeve is provided on the outer periphery of the end of the end extension rod away from the tensioning screw, and an elastic rubber anti-slip ring is connected to the open end of the limiting sleeve, a built-in cavity is provided inside the side wall thickness of the limiting sleeve, and a square column is inserted through the side wall of the limiting sleeve at a position corresponding to the position of the built-in cavity; one end of the square column protrudes from the side wall surface of the limiting sleeve, and the other end passes through the built-in cavity and extends into the inner cavity of the limiting sleeve, and a chamfered clamp is provided on the end of the square column extending into the inner cavity of the limiting sleeve; a synchronous outer ring arranged in the built-in cavity is also sleeved and fixed on the outer periphery of the square column, and a reset spring is connected to the synchronous outer ring, and the end of the reset spring away from the synchronous outer ring is connected to the end of the built-in cavity; a plurality of chamfered grooves arranged linearly and adapted to the chamfered clamp are evenly provided on the surface of the end extension rod.

[0008] As an optional solution of the technical solution of the present application document, a guide slider is connected to the side wall of the inner cavity of the limiting sleeve, and a straight groove adapted to the guide slider is opened on the side wall of the end extension rod.

[0009] As an optional solution of the technical solution of this application document, the square column is a rectangular parallelepiped structure.

[0010] As an optional solution of the technical solution of this application document, a vibration motor is connected to the side wall of the clamping seat.

[0011] As an optional solution of the technical solution of this application document, the tensioning screws are distributed on the side wing seats in a dense manner at the bottom and sparsely at the top.

[0012] As an optional solution of the technical solution of this application document, the outer diameter of the end extension rod is equal to the outer diameter of the tensioning screw.

[0013] Beneficial effects: One or more technical solutions provided in the technical solution of the present application have at least the following technical effects or advantages: 1. Before preparing the concrete underground pipeline, the present application can not only clamp and fix the concrete casting formwork by the drive of two hydraulic cylinders, but also subsequently tighten the nuts by tools such as wrenches, so that the two clamping seat stirrups are on the outer periphery of the concrete casting formwork, thereby realizing the reinforcement and support treatment of the concrete casting formwork. In this way, when pouring concrete into the concrete casting formwork, not only the stability of the fixation of the concrete casting formwork can be guaranteed, but also the concrete casting formwork can be effectively prevented from running or expanding, thereby ensuring the product quality of the concrete underground pipeline.

[0014] 2. When the nut is tightened and concrete is poured into the concrete casting formwork, the concrete inside the concrete casting formwork will be affected by the vibration of the vibration motor, which will cause the loose concrete particles to be compacted, reduce the gaps between the particles inside the concrete, and improve the compactness of the concrete.

[0015] 3. Before pouring concrete into the concrete casting formwork, tighten the nut, put the limiting sleeve on the end of the end extension rod, and insert the guide slider into the straight groove on the side wall of the end extension rod while the limiting sleeve is put on the end of the end extension rod, and then push the limiting sleeve. When the limiting sleeve slides toward the nut at the end of the end extension rod, the chamfering clamps are sequentially inserted into different chamfering grooves under the action of the inclined surface of the chamfering clamp, and when the chamfering clamp is blocked by the vertical surface of the chamfering groove, After being buckled into the chamfered slot, it can only move in the direction close to the nut and cannot move backward in the opposite direction. Therefore, when the nut is tightened, the limiting sleeve is fixed to the end extension rod through the chamfered clip buckle on the end of the square column, so that the elastic rubber anti-slip ring is tightly against the end of the nut, preventing the nut from loosening under the vibration of the vibration motor, ensuring that the clamping seat of the device can firmly clamp the concrete casting template when preparing concrete underground pipelines, thereby ensuring the reinforcement and support effect of the concrete casting template.

[0016] 4. As concrete is continuously poured into the interior of the concrete casting formwork, the pressure on the lower part of the inner cavity side wall of the concrete casting formwork is relatively large. Since the tensioning screws are densely distributed at the bottom and sparsely distributed at the top on the side wing seats, when the nuts on the tensioning screws are tightened, under the tension of multiple tensioning screws that are relatively dense under the side wing seats, the clamping force of the clamping seat on the lower part of the concrete casting formwork is greater than that on the upper part of the clamping seat. Therefore, it is beneficial to further improve the reinforcement and support effect of the concrete casting formwork, so that the concrete casting formwork can be more firmly supported during the concrete pouring process.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application. The present application is further described in detail below in combination with the drawings in the specification.

[0023] Reference Figures 1 to 3 The embodiment of the present application provides an auxiliary pouring pool for concrete on the surface of a ductile iron jacking pipe, comprising a pouring pool 1 and a support platform 2 connected to the bottom end of the inner cavity of the pouring pool 1; a concrete pouring template 3 with a ductile iron jacking pipe inside is placed on the top of the support platform 2, and two brackets are symmetrically connected to the left and right of the support platform 2, each bracket is connected to a hydraulic cylinder 7, and the opposite ends of the two hydraulic cylinders 7 are connected to a clamping seat 4, and the front and rear ends of the clamping seat 4 are connected to side wing seats 5; a plurality of tensioning screws 6 are connected to the side wing seats 5 connected at both ends of one of the clamping seats 4 from top to bottom, and the other end of the tensioning screw 6 passes through another clamping seat 4 and is threadedly connected to a nut 10.

[0024] A steel cage is welded to the outer periphery of the ductile iron jacking pipe, and then the ductile iron jacking pipe with the steel cage fixed on the outer periphery is placed into the concrete casting formwork 3. Before preparing the concrete underground pipeline, the present application can not only clamp and fix the concrete casting formwork 3 by the two clamping seats 4 driven by the two hydraulic cylinders 7, but also subsequently tighten the nuts 10 by tools such as wrenches, so that the two clamping seats 4 stirrups are on the outer periphery of the concrete casting formwork 3 to achieve reinforced support for the concrete casting formwork 3. In this way, when pouring concrete into the steel cage between the concrete casting formwork 3 and the ductile iron jacking pipe, not only the stability of the fixation of the concrete casting formwork 3 can be guaranteed, but also the concrete casting formwork 3 can be effectively prevented from running or expanding, thereby ensuring the product quality of the concrete underground pipeline.

[0025] A vibration motor 8 is also connected to the side wall of the clamping seat 4. When the nut 10 is tightened and concrete is poured into the concrete pouring template 3, the concrete inside the concrete pouring template 3 is vibrated by the vibration motor 8, which densifies the loose concrete particles, reduces the gaps between the particles inside the concrete, and improves the compactness of the concrete.

[0026] The tensioning screws 6 are distributed on the side wing seats 5 in a dense distribution at the bottom and sparse distribution at the top. As concrete is continuously poured into the interior of the concrete casting template 3, the pressure on the lower part of the inner cavity side wall of the concrete casting template 3 is relatively large. Since the tensioning screws 6 are distributed on the side wing seats 5 in a dense distribution at the bottom and sparse distribution at the top; therefore, after tightening the nuts 10 on the tensioning screws 6, under the tension of the multiple tensioning screws 6 that are relatively dense below the side wing seats 5, the clamping force of the clamping seat 4 on the lower part of the concrete casting template 3 is greater than that on the upper part of the clamping seat 4, which is conducive to further improving the reinforcement and support effect of the concrete casting template 3, so that during the concrete pouring process, the concrete casting template 3 can be more firmly supported.

[0027] Reference Figure 3 and Figure 4 The embodiment of the present application provides a ductile iron top pipe surface concrete auxiliary pouring pool, and the end of the tensioning screw 6 away from the side wing seat 5 to which it is connected is also connected to an end extension rod 17; the outer periphery of the end of the end extension rod 17 away from the tensioning screw 6 is sleeved with a limiting sleeve 9, and the open end of the limiting sleeve 9 is connected to an elastic rubber anti-slip ring 18, and the side wall thickness of the limiting sleeve 9 is provided with a built-in cavity inside, and the side wall of the limiting sleeve 9 is penetrated and inserted with a square column 11 at the position corresponding to the position of the built-in cavity;

[0028] One end of the square column 11 protrudes from the side wall surface of the limiting sleeve 9, and the other end passes through the built-in cavity and extends into the inner cavity of the limiting sleeve 9, and a chamfered clamp 14 is provided on the end of the square column 11 extending into the inner cavity of the limiting sleeve 9; the outer periphery of the square column 11 is also sleeved and fixed with a synchronous outer ring 12 arranged in the built-in cavity, and the synchronous outer ring 12 is connected to a return spring 13, and the end of the return spring 13 away from the synchronous outer ring 12 is connected to the end of the built-in cavity;

[0029] The surface of the end extension rod 17 is evenly provided with a plurality of chamfering grooves 15 arranged linearly and adapted to the chamfering clamp 14, such as Figure 4 The longitudinal section of the chamfered groove 15 is a right triangle, and the longitudinal section of the chamfered clamping head 14 is also a right triangle.

[0030] A guide slider 16 is connected to the inner side wall of the limiting sleeve 9, and a straight groove matching the guide slider 16 is provided on the side wall of the end extension rod 17. The square column 11 is a rectangular parallelepiped structure. The outer diameter of the end extension rod 17 is equal to the outer diameter of the tightening screw 6.

[0031] Before pouring concrete into the concrete pouring formwork 3, tighten the nut 10, put the limiting sleeve 9 on the end of the end extension rod 17, and insert the guide slider 16 into the straight groove on the side wall of the end extension rod 17 while the limiting sleeve 9 is put on the end of the end extension rod 17, and then push the limiting sleeve 9;

[0032] When the limiting sleeve 9 slides at the end of the end extension rod 17 toward the direction of the nut 10, under the action of the inclined surface of the chamfered clamp 14, the chamfered clamp 14 is successively clamped into different chamfered grooves 15, and under the obstruction of the vertical surface of the chamfered groove 15, when the chamfered clamp 14 is buckled into the chamfered groove 15, it can only move in the direction close to the nut 10 and cannot retreat in the opposite direction; therefore, when the nut 10 is tightened, the limiting sleeve 9 is buckled and fixed on the end extension rod 17 by the chamfered clamp 14 on the end of the square column 11, so that the elastic rubber anti-slip ring 18 is tightly against the end of the nut 10, preventing the nut 10 from loosening under the vibration of the vibration motor 8, ensuring that the clamping seat 4 of the device can firmly clamp the concrete casting template 3 when preparing the concrete underground pipeline, thereby ensuring the reinforcement and support effect of the concrete casting template 3.

[0033] It should be noted that the electrical components mentioned in this article are all connected to the main controller and 220V mains electricity, and the main controller is a common prior art computer that plays a control role. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
