Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to a forming device for concrete ditch covers. Background Technique

[0002] Ditches can be roughly divided into two types. One is the rainwater sewer that can be seen everywhere by the roadside, and the other is the sewage sewer that conveys the wastewater of homes and factories to the sewage treatment plant in a closed pipeline. In urban road construction, there are many large and small ditches dug on the roadside. The ditches play a very important role in facilitating the timely discharge of sewage in the city. Above the ditches, a layer of ditch covers is usually laid.

[0003] For the existing ditch cover forming devices, concrete is generally poured directly on the ditch. When demolding the ditch cover after pouring, since the concrete cover is not aligned with the already demolded cover, it still needs to be carried again, which is time-consuming and laborious and is not conducive to the production of ditch covers. In view of this, we propose a forming device for concrete ditch covers. Content of the Utility Model

[0004] The purpose of the utility model is to provide a forming device for concrete ditch covers to solve the problem that in the existing ditch cover forming devices, concrete is generally poured directly on the ditch. When demolding the ditch cover after pouring, since the concrete cover is not aligned with the already demolded cover, it still needs to be carried again, which is time-consuming and laborious and is not conducive to the production of ditch covers as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A forming device for concrete ditch covers includes a flipping frame and a forming mold. Inside the forming mold is a ditch cover formed by concrete pouring. The forming mold is slidably connected to the flipping frame. Rotating shafts are rotatably connected to the left and right sides of the flipping frame. Roller wheels are fixedly installed at the outer ends of the rotating shafts. Handrails are fixedly installed on the left and right sides of the upper end of the flipping frame. A hollow cavity is provided in the middle of the flipping frame. Guide grooves are symmetrically arranged on both sides of the hollow cavity. The front ends of the guide grooves are open, and multiple guide inclined surfaces are provided on the opening sides of the guide grooves. A pressure boosting pad is provided at the upper end of the guide groove. The pressure boosting pad is connected to the flipping frame by bolts. Protruding blocks are arranged at intervals on the lower end surface of the pressure boosting pad, and a guiding surface is provided on the side of the pressure boosting pad corresponding to the opening of the guide groove.

[0006] Preferably, the roller wheels are arranged outside the flipping frame, and the roller wheels and the flipping frame are arranged at intervals.

[0007] Preferably, the distance between the rotating shaft and the lower end surface of the flipping frame is greater than the distance between the rotating shaft and the front end surface of the flipping frame.

[0008] Preferably, the molding die is arranged inside the hollow cavity, and the front end of the hollow cavity is open.

[0009] Preferably, the width of the molding die is smaller than the maximum distance between adjacent guide grooves.

[0010] Preferably, the width of the turning frame is greater than the maximum width of the molding die.

[0011] Preferably, the center lines of the armrest rod and the rotating shaft are perpendicular to each other.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. For the molding device for concrete ditch covers, when demolding the ditch covers after pouring, the contact between the turning frame and the ground is a rolling contact, which reduces the contact friction and improves the service life of the molding device; at the same time, through the rolling contact of the rolling wheels with the ditch, it is easy to push the molding device, making the concrete covers aligned with the already demolded covers, saving time and effort, facilitating the pouring of the ditch covers on the ditch, and reducing the occupied area.

[0014] 2. For the molding device for concrete ditch covers, by setting the ditch cover molding die as laminated bamboo lumber, the laminated bamboo lumber has high strength and stiffness, high dimensional stability, good environmental protection performance, low manufacturing cost, and is easy for ditch molding processing.

[0015] 3. For the molding device for concrete ditch covers, a pressure - increasing pad is arranged on the upper side of the guide groove. When demolding the ditch covers after pouring, in addition to the extrusion effect, the pressure - increasing pad also receives the pulling force provided by the ditch covers towards the opening side of the guide groove; at this time, through the action of the raised blocks arranged on the pressure - increasing pad, the downward force of the ditch covers can be restricted, thereby further ensuring the safety of the demolding process of the ditch covers.

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

[0023] Example: See Figures 1-5 The present invention provides a technical solution: a forming device for concrete ditch covers. This solution addresses the problem of existing ditch cover forming devices, which typically cast concrete directly on the ditch. When the ditch cover is demolded after casting, the concrete cover is not aligned with the demolded cover, requiring further transport. This is time-consuming and labor-intensive, hindering the production of ditch covers. The specific solution is as follows: it includes a turning frame 1 and a forming mold 6. The ditch cover is cast by directly pouring concrete into the inner side of the forming mold 6.

[0024] It is worth noting that the forming mold 6 is made of bamboo laminated wood. Bamboo laminated wood is a new type of composite material made from bamboo. The production process of bamboo laminated wood is as follows:

[0025] Material Selection and Cutting: Select high-quality bamboo and saw it into bamboo tubes according to the required length. The variety and quality of bamboo have a significant impact on the performance of bamboo laminated lumber. Generally, bamboo with moderate growth age, uniform wall thickness, and no obvious defects is selected.

[0026] Slicing and sorting: Slice the bamboo tube according to the specified width and sort it according to different thickness requirements to ensure that the specifications of the bamboo slices meet the production standards.

[0027] Rough planing: Use a rough planer to remove the green, yellow and partitions of the bamboo strips, and plane the curved bamboo strips to make them rectangular bamboo strips for subsequent gluing operations. At the same time, perform precise width determination and planing to improve the accuracy of the bamboo strips.

[0028] Carbonization: The bamboo strips are tied together with their front and back facing each other, and then carbonized. The carbonization process consists of two stages: high-temperature carbonization, desugaring, and degreasing, followed by low-temperature drying. This step improves the stability and durability of the bamboo, and effectively prevents insect infestation and mildew.

[0029] Fine planing and sorting: The carbonized bamboo strips are finely planed to further improve the flatness and smoothness of the bamboo strips. At the same time, each bamboo strip is selected according to quality and color to ensure the appearance quality of the bamboo laminated lumber.

[0030] Gluing and hot pressing: Glue is applied to the selected bamboo strips, and then the bamboo strips are glued together by hot pressing to form the boards of bamboo laminated lumber. During hot pressing, parameters such as pressure, temperature and time need to be controlled to ensure the gluing quality.

[0031] The forming die 6 is processed with bamboo laminated lumber because bamboo laminated lumber has higher strength and stiffness, and its mechanical property indexes such as tensile strength, bending strength and compressive strength are better than those of ordinary wood. For example, the average tensile strength of bamboo is 208.2 MPa, which is about 2 times that of wood. High dimensional stability: After processes such as hydrothermal treatment and gluing and pressing, bamboo laminated lumber has a low shrinkage rate and expansion coefficient, good dimensional stability, and is not easy to deform or crack. Strong wear resistance: Bamboo itself has a high hardness. After processing, the surface of bamboo laminated lumber is hard and has strong wear resistance, which is suitable for making products such as furniture and floors that are often rubbed. Good environmental protection: Bamboo is a renewable resource with a fast growth rate. The adhesives used in the production process of bamboo laminated lumber have also been improved, with a low free formaldehyde content, meeting the environmental protection requirements.

[0032] Please refer to Figure 1 and Figure 2 , the width of the turnover frame 1 is greater than the maximum width of the forming die 6. A trench cover plate 7 made of concrete is arranged inside the forming die 6. The forming die 6 is slidably connected to the turnover frame 1. Rotating shafts 9 are rotatably connected to the left and right sides of the turnover frame 1. The distance between the rotating shaft 9 and the lower end face of the turnover frame 1 is greater than the distance between the rotating shaft 9 and the front end face of the turnover frame 1. A rolling wheel 8 is fixedly installed at the outer end of the rotating shaft 9. The rolling wheel 8 is arranged outside the turnover frame 1, and the rolling wheel 8 and the turnover frame 1 are arranged at intervals. The rolling wheel 8 can turn at a certain angle on the turnover frame 1. When demolding the trench cover plate 7 after pouring, the contact between the turnover frame 1 and the ground is rolling contact, reducing the contact friction and improving the service life of the forming device; at the same time, through the rolling contact of the rolling wheel 8 with the trench, it is easy to push the forming device, making the concrete cover plate and the already demolded cover plate aligned, facilitating the pouring of the trench cover plate on the trench and reducing the occupied area.

[0033] Furthermore, handrails 3 are fixedly installed on the left and right sides of the upper end of the turnover frame 1. The center lines of the handrails 3 and the rotating shaft 9 are perpendicular to each other. Silicone with a flexible material can be set outside the handrails 3 to protect the hands of operators. The setting of the handrails 3 can facilitate the turnover of the turnover frame 1. Setting it on both sides can facilitate selective operation on both sides. A hollow cavity 2 is arranged in the middle of the turnover frame 1. The forming die 6 is arranged inside the hollow cavity 2, and the front end of the hollow cavity 2 is open.

[0034] In this embodiment, guide grooves 4 are symmetrically arranged on both sides of the hollow cavity 2, and the width of the forming die 6 is smaller than the maximum distance between adjacent guide grooves 4. The front end of the guide groove 4 is open, and a plurality of guide inclined surfaces 5 are arranged on the opening side of the guide groove 4. A pressure boosting pad 41 is arranged at the upper end of the guide groove 4. The pressure boosting pad 41 is connected to the turnover frame 1 by bolts. Protrusion blocks 42 are arranged at intervals on the lower end surface of the pressure boosting pad 41, and a guiding surface 43 is arranged on one side of the pressure boosting pad 41 corresponding to the opening of the guide groove 4. Among them, the material of the pressure boosting pad 41 is flexible rubber. In the initial state, as Figure 1 shown, it is convenient for the pouring operation of concrete, and the pressure boosting pad 41 is only subjected to extrusion; when demolding the channel cover plate 7 after pouring, in addition to the extrusion, the pressure boosting pad 41 is also subjected to the pulling force provided by the channel cover plate 7 towards the opening side of the guide groove 4; at this time, through the action of the protrusion blocks 42 arranged on the pressure boosting pad 41, the downward acting force of the channel cover plate 7 can be restricted, thereby further ensuring the safety of the demolding process of the channel cover plate 7.

[0035] Working principle: For this concrete channel cover plate forming device, during pouring, the opening of the forming die 6 faces upwards, and the concrete is poured inside the forming die 6; after pouring and standing for a certain period of time, by inserting the turnover frame 1 from one side of the forming die 6, the side flange of the forming die 6 is placed in the guide groove 4 and gradually pushed forward from the back, so that the turnover frame 1 catches the forming die 6; as Figure 3 shown in the schematic diagram, by flipping the forming device, the demolding operation of the channel cover plate 7 inside the forming die 6 can be carried out.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
