Description

Technical Field

[0001] This utility model relates to the field of tunnel construction equipment technology, specifically a construction template trolley. Background Technology

[0002] Formwork trolleys are specialized formwork equipment used in the secondary lining of tunnels, primarily for the construction of cement formwork for the inner walls of tunnels. Formwork trolleys mainly include simple formwork trolleys, fully hydraulic automatic walking formwork trolleys, and space frame formwork trolleys. Among these, fully hydraulic formwork trolleys can be further divided into side-top arch type, full-circular needle beam type, bottom-form needle beam type, and full-circular through-type, etc. In hydraulic tunnel and bridge construction, lifting slipform, jacking slipform, and flipping formwork are also commonly used.

[0003] For example, the tunnel construction formwork trolley disclosed in the authorization announcement number CN 222650004 U, although it realizes a tunnel construction formwork trolley including a main frame, and a formwork mechanism and a support mechanism set on the main frame, with the support mechanism installed on the main frame and the formwork mechanism supported on the periphery of the main frame by the support mechanism, does not solve the problem that existing general formwork trolleys are generally too large and heavy, and when they need to be moved, they can only be disassembled first, and then reassembled after reaching the designated location. This working method is time-consuming and labor-intensive, and it cannot improve the effective movement of construction pouring molds when they need to be moved. Utility Model Content

[0004] The purpose of this utility model is to provide a construction template trolley to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A construction template trolley includes an inner mold mechanism, which includes a base plate, a first moving module, and a lifting support module. The first moving module is provided at the bottom end of the base plate, and the lifting support module is provided at the top end of the base plate.

[0007] The lifting support module is equipped with an outer mold mechanism at its top. The outer mold mechanism includes a structural support rod, a second moving module, an outer mold top plate, and a template fixing module. The bottom ends of the two structural support rods are respectively equipped with the second moving module. The top end of the structural support rod is equipped with the outer mold top plate, and the bottom end of the outer mold top plate is equipped with the template fixing module.

[0008] Preferably, the first and second moving modules each include a motor, and the output end of the motor is equipped with a moving wheel. The advantage is that, generally, template trolleys are too large and heavy, and when they need to be moved, they can only be disassembled first and then reassembled after reaching the designated location. This working method is time-consuming and labor-intensive. Therefore, by setting the first and second moving modules in the inner mold mechanism and the outer mold mechanism respectively, and driving the moving wheel to rotate through the motor, the trolley can be moved quickly and conveniently, which can effectively improve the practicality of the trolley.

[0009] Preferably, the lifting support module includes a lifting cylinder, a movable support rod at the top of the lifting cylinder, an inner mold top plate at the top of the movable support rod, and adjusting shafts rotatably mounted on both sides of the inner mold top plate. An inner mold side plate is mounted on one side of each adjusting shaft. The advantage is that during support, the lifting cylinder first pushes the inner mold top plate against the bottom surface of the construction casting mold. Then, several inner mold hydraulic support rods push the inner mold side plates tightly against both sides of the construction casting mold for fixation. When it is necessary to move the inner mold mechanism, the inner mold side plates are pulled and retracted by the inner mold hydraulic support rods. Then, some of the inner mold hydraulic support rods used for fixing are removed, and the lifting cylinder retracts the movable support rods to lower the height of the inner mold top plate. After lowering to a suitable height, the moving wheels are driven by a motor to rotate, thus enabling quick and convenient movement and improving actual work efficiency.

[0010] Preferably, a plurality of internal mold hydraulic support rods are connected between the movable support rod and the inner mold side plate. The two sides of the internal mold hydraulic support rods are respectively connected to one side of the movable support rod and the inner mold side plate through a plurality of internal mold connecting shafts. The advantage is that, when providing support, the inner mold top plate is first pushed against the bottom surface of the construction casting mold by the lifting cylinder, and then the inner mold side plate is pushed tightly against both sides of the construction casting mold by the plurality of internal mold hydraulic support rods for fixation.

[0011] Preferably, the template fixing module includes a side-pulling cylinder, and an outer mold side plate is rotatably mounted on one bottom end of the side-pulling cylinder. An outer mold hydraulic support rod is connected between the outer mold side plate and the structural support rod. The advantage is that, during fixing, the outer mold side plate is pulled by the side-pulling cylinder to clamp the construction casting mold, ensuring the stability during fixing.

[0012] Preferably, the bottom end of the outer mold hydraulic support rod is provided with a pin. The advantage is that the bottom end of the construction casting mold is fixed by connecting the bottom end of the pin, which can effectively improve the stability during fixing.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In use, this type of construction template trolley first uses a side-pulling hydraulic cylinder to pull the outer mold side plate to clamp and fix the construction pouring mold. During fixing, the bottom end of the construction pouring mold is fixed by connecting the bottom pin shaft. Then, the moving wheels are driven by a motor to rotate and move to the top of the inner mold mechanism. Then, the lifting hydraulic cylinder pushes the inner mold top plate to press against the bottom surface of the construction pouring mold. Then, several inner mold hydraulic support rods push the inner mold side plate to be tightly attached to both sides of the construction pouring mold for fixation. After the overall support is completed, the construction pouring work is carried out on the construction pouring mold.

[0015] 2. This type of construction formwork trolley has an inner membrane mechanism that is an integral structure, with 10-meter sections forming a unit. Existing formwork trolleys are generally too large and heavy, requiring disassembly before movement and reassembly at the designated location. This method is time-consuming and labor-intensive, and it doesn't effectively move the construction casting mold. Therefore, an outer mold mechanism is provided. This mechanism grips the construction casting mold and moves it longitudinally from the top of the inner mold mechanism until it reaches the predetermined top for support. This significantly improves work efficiency during the casting process. Attached Figure Description

Generally, template trolleys are too large and heavy, and when they need to be moved, they can only be disassembled first and then reassembled after reaching the designated location. This working method is time-consuming and labor-intensive. Therefore, by setting the first moving module 2 and the second moving module 5 in the inner mold mechanism and the outer mold mechanism respectively, and driving the moving wheel 9 to rotate through the motor 8, the trolley can be moved quickly and conveniently, which can effectively improve the practicality of the trolley.

[0026] In this embodiment, preferably, the lifting support module 3 includes a lifting cylinder 10, a movable support rod 11 at the top of the lifting cylinder 10, an inner mold top plate 12 at the top of the movable support rod 11, and adjusting shafts 13 rotatably arranged on both sides of the inner mold top plate 12.

During support, the lifting cylinder 10 first pushes the inner mold top plate 12 to press against the bottom surface of the construction casting mold. Then, several inner mold hydraulic support rods 15 push the inner mold side plates 14 to be fixed tightly against both sides of the construction casting mold. When it is necessary to move the inner mold mechanism, the inner mold side plates 14 are pulled and retracted by the inner mold hydraulic support rods 15. Then, some of the inner mold hydraulic support rods 15 used for fixing are removed, and then the lifting cylinder 10 retracts the movable support rods 11 to lower the height of the inner mold top plate 12. After lowering to a suitable height, the motor 8 drives the moving wheels 9 to rotate, thereby enabling quick and convenient movement and improving actual work efficiency.

[0027] In this embodiment, preferably, a plurality of internal mold hydraulic support rods 15 are connected between the movable support rod 11 and the inner mold side plate 14.

During fixing, the bottom of the construction casting mold is connected to the bottom end by a pin 20. Then, a motor 8 drives the moving wheels 9 to rotate, moving the trolley to the top of the inner mold mechanism. Next, a lifting cylinder 10 pushes the inner mold top plate 12 to press against the bottom surface of the construction casting mold. Then, several inner mold hydraulic support rods 15 push the inner mold side plate 14 to press tightly against both sides of the construction casting mold for fixation. After the overall support is completed, the construction casting mold is then... The advantage of this method for casting is that the inner mold mechanism is an integral structure, with each 10 meters forming a unit. Existing formwork trolleys are generally too large and heavy, requiring disassembly and reassembly upon reaching the designated location when needed.
