Description

Technical Field

[0001] This utility model relates to the field of concrete manhole casting template technology, specifically a prefabricated assembled concrete manhole casting template. Background Technology

[0002] In municipal engineering construction, concrete inspection wells are an important component of underground drainage systems, and their prefabrication quality directly affects the stability and service life of the entire drainage system. With the promotion of prefabricated building technology, prefabricated concrete inspection wells have been widely used due to their advantages such as high construction efficiency and stable quality. As a key tool in the production of prefabricated inspection wells, the structural design and performance of the casting formwork are of paramount importance.

[0003] A precast concrete manhole casting template, disclosed in publication number CN109930629B, is precast as a whole with the manhole chamber in one go. This not only effectively solves the leakage problem, but also greatly improves the integrity and rigidity of the manhole chamber.

[0004] The precast concrete manhole casting formwork can be adjusted in height via a winch for easy installation. However, the device lacks a structure for rotating the formwork. When the formwork needs to be adjusted during installation, workers must manually adjust its position, which is inconvenient and requires improvement. Utility Model Content

[0018] 1. The precast concrete manhole casting template installation mechanism uses hydraulic cylinders and servo motors to achieve vertical lifting and 360° rotation of the arc-shaped clamping plate. It can automatically grab, position and adjust the position of the outer mold. The bidirectional threaded rod drives the threaded plate to move the arc-shaped clamping plate inward or outward synchronously, quickly clamping or releasing the mold and reducing manual operation.

[0019] 2. In the precast concrete manhole casting template, the adjustment mechanism uses a cylinder to drive a slider to slide along the moving groove of the load-bearing plate, thereby achieving fine-tuning of the inner mold's horizontal position. The sealing groove of the bottom mold fits into the bottom of the outer mold, and the engagement of the insertion rod with the fixing hole effectively prevents grout leakage during concrete pouring.

[0038] Example 2

[0039] Please see Figure 1-6 Furthermore, based on Embodiment 1, the adjustment mechanism 4 includes a cylinder 41, which is fixedly connected to the back end of the load-bearing plate 1. A slider 42 is fixedly connected to the front of the cylinder 41, and a fixing plate 43 is fixedly connected to the top of the slider 42. A bottom mold 44 is provided on the top of the fixing plate 43, and a bolt 45 is threadedly connected inside the bottom mold 44. An inner mold 6 is provided on the top of the bottom mold 44.

[0040] Furthermore, a moving groove corresponding to the movement trajectory of the slider 42 is provided on the inner side of the load-bearing plate 1, and the slider 42 is slidably connected to the inside of the moving groove. By moving the slider 42 inside the load-bearing plate 1, the slider 42 can slide inside the load-bearing plate 1, making the slider 42 more stable during movement.

[0041] Furthermore, the inner side of the fixing plate 43 is provided with a threaded hole corresponding to the position of the bolt 45, and the bolt 45 is threaded into the inner side of the threaded hole. The bottom mold 44 can be installed on the top of the fixing plate 43 by means of the bolt 45.

[0042] Furthermore, the bottom mold 44 has a sealing groove inside that corresponds to the position of the outer mold 2, and the bottom of the outer mold 2 fits into the bottom of the sealing groove. Through the sealing groove, the outer mold 2 can be inserted into the bottom mold, making the outer mold 2 more tightly placed on top of the bottom mold 44.

[0043] Furthermore, the bottom mold 44 has a fixing hole inside that corresponds to the position of the insert rod 5, and the insert rod 5 is inserted into the inside of the fixing hole.

[0044] In actual operation, when this device is used, first place the bottom mold 44 on top of the fixed plate 43, and install the bottom mold 44 on top of the fixed plate 43 with bolts 45. Place the inner mold 6 on the top front of the load-bearing plate 1. Open the hydraulic cylinder 35 through the PLC controller, so that the hydraulic cylinder 35 drives the support 302 and the rotating plate 32 to move downward through the lifting plate 37, so that the arc-shaped clamping plate 31 moves to the outside of the inner mold 6. Open the drive motor 38 through the PLC controller, so that the drive motor 38 drives the threaded plate 39 to move through the bidirectional threaded rod 301. The threaded plate 39 moves the arc-shaped clamping plate 31, which clamps the inner mold 6. The PLC controller opens the hydraulic cylinder 35, which moves the lifting plate 37 and the clamped inner mold 6 upward. The PLC controller opens the air cylinder 41, which pushes the slider 42 and the fixing plate 43 to move forward, so that the fixing plate 43 moves to the bottom of the inner mold 6. The PLC controller opens the hydraulic cylinder 35, which moves the inner mold 6 downward, so that the inner mold 6 can be placed on the top of the bottom mold 44.

[0045] When the outer mold 2 needs to be installed, after the outer mold 2 is clamped by the arc-shaped clamping plate 31, the servo motor 34 is turned on by the PLC controller, so that the servo motor 34 drives the rotating plate 32 to rotate through the rotating shaft 303. The rotating plate 32 can drive the clamped outer mold 2 to rotate, so that the insertion rod 5 inside the outer mold 2 can correspond to the hole opened inside the bottom mold 44, so that the outer mold 2 can be stably inserted into the top of the bottom mold 44 and make close contact with the bottom mold 44, effectively preventing grout leakage during concrete pouring.
