Description

Technical Field

[0001] This utility model relates to the field of underground utility tunnel construction technology, and more specifically, to an auxiliary trolley. Background Technology

[0002] In urban underground space development, integrated utility tunnels, as public tunnels for the centralized laying of various municipal pipelines such as electricity, communications, water supply, and drainage, are increasingly being built on a large scale. Currently, cast-in-place concrete utility tunnels are one of the main construction methods, and their construction process typically relies on formwork systems to shape the internal structure and dimensions of the tunnel.

[0003] In existing technologies, the installation and dismantling of the inner formwork for utility tunnels largely rely on a combination of large lifting equipment and manual labor. Specifically, the hoisting, positioning, adjustment, and subsequent dismantling and transportation of the inner formwork not only require frequent use of heavy machinery such as cranes, but also suffer from the following significant drawbacks: the movement, positioning, and demolding of the inner formwork depend entirely on external lifting equipment, resulting in complex process connections, long time commitments for machinery and equipment, long single-cycle operation periods, and slow overall construction progress; the large size and weight of the inner formwork lead to poor stability during installation, especially during dismantling and demolding, making it prone to swaying or tipping over, posing a safety threat to construction workers. Utility Model Content

[0004] This utility model provides an auxiliary vehicle that can overcome some or more defects of the prior art.

[0005] According to the present invention, an auxiliary trolley includes: a trolley body, the trolley body including a rectangular mounting frame, a reinforcing frame inside the mounting frame, and wheels at the bottom of the reinforcing frame; the mounting frame also includes lifting mechanisms located on both sides of the reinforcing frame, the lifting mechanisms being used to push the trolley body upward.

[0006] This invention enables the following steps during the construction of a pipe gallery: First, the foundation of the pipe gallery is poured, and reinforcing mesh is tied at both ends of the foundation. Then, construction workers use a crane to lift the main body of the trolley to one end of the foundation. Next, the left and right inner molds are lifted onto the trolley. The second motor is then started, driving the wheels to move the trolley to the designated location. Construction workers then use jacks to push the left and right inner molds towards and against the reinforcing mesh. A support frame is then installed between the left and right inner molds to secure them. Finally, the second hydraulic cylinder is activated to lift the trolley... After the trolley is lifted to move the left and right inner molds to the designated positions, support rods are installed below the left and right inner molds to support them. Then, the construction workers activate the second hydraulic cylinder to lower the height of the trolley, and then activate the second motor to drive the traveling wheels to detach the trolley from the left and right inner molds. After the trolley is detached from the left and right inner molds, the top plate is installed on the top of the left and right inner molds, and the outer templates are installed on both sides of the left and right inner molds. Finally, the above operation is repeated to install another inner mold. Adjacent inner molds are fastened together with positioning pins and screws. After all the inner and outer molds are installed, concrete is poured. After the pouring is completed, move the trolley to the bottom of the left and right inner molds. First, remove the positioning pins and screws to disconnect the connection between the adjacent inner molds. Then, start the second hydraulic cylinder to lift the trolley to the bottom of the inner mold. Then, loosen the support rod under the inner mold so that the inner mold is mounted on the trolley. Then, the construction workers stand on the support plate of the trolley and remove the support frame connecting the left and right inner molds. Then, use jacks to pull the left and right inner molds towards the middle so that the left and right inner molds are separated from the side walls of the pipe rack. After that, start the second hydraulic cylinder to lower the height of the trolley so that the inner mold is separated from the top wall of the pipe rack. Finally, the trolley transports the inner mold away. Repeat the above operation to remove all the inner molds. The installation and removal of the inner formwork rarely relies on heavy machinery such as cranes, thus reducing equipment costs. Furthermore, the installation and removal of the inner formwork are carried out inside the pipe gallery by construction personnel and trolleys, and are not affected by external equipment due to the movement of equipment, which greatly improves the efficiency of the installation and removal of the inner formwork. In addition, there is no need to lift the inner formwork during the installation and removal process, which avoids the inner formwork shaking or tipping during the lifting process and posing a safety threat to the construction personnel.

[0007] Preferably, the lifting mechanism includes a first reinforcing plate arranged along the width of the mounting frame, with a second hydraulic cylinder at each end of the first reinforcing plate, and a support foot connected to the second hydraulic cylinder below the second hydraulic cylinder.

[0008] With this invention, the support foot is connected to the hydraulic rod of the second hydraulic cylinder and contacts the bottom surface, thereby preventing the hydraulic rod from contacting the bottom surface and thus damaging the hydraulic rod.

[0009] Preferably, a second reinforcing plate is provided on the side of the first reinforcing plate away from the mounting frame. The second reinforcing plate and the mounting frame together form a first limiting interval. A double-rod hydraulic cylinder is provided in the first limiting interval. The hydraulic rod of the double-rod hydraulic cylinder passes through the mounting frame, and a guide wheel is provided at one end of the hydraulic rod that passes through the mounting frame.

[0010] With this invention, during the movement of the trolley, the double-rod hydraulic cylinder presses the guide wheel against the lower side wall of the pipe gallery, enabling the trolley to move stably.

[0011] Preferably, the reinforcement frame includes a base plate connected to the mounting frame, and two third reinforcement plates are provided above the base plate along the length of the base plate. At both ends of the third reinforcement plates are fourth and fifth reinforcement plates spaced apart along the length of the third reinforcement plates. The third reinforcement plates, fourth reinforcement plates, fifth reinforcement plates and the base plate together constitute a second limiting interval, and a second motor for driving the rotation of the walking wheels is provided in the second limiting interval.

[0012] With this invention, the fourth and fifth reinforcing plates are welded to the inner sidewall of the mounting frame at both ends, and the bottom plate sidewall is welded to the inner sidewall of the mounting frame; the reinforcing frame effectively improves the overall structural strength of the trolley. The fourth, fifth, first, and second reinforcing plates are respectively provided with a first hole, a second hole, a third hole, and a fourth hole for the line to pass through, so as to facilitate the line to pass through the fourth, fifth, first, and second reinforcing plates and connect to the second hydraulic cylinder and the second motor.

[0013] The third, fourth, and fifth reinforcing plates, together with the base plate, form multiple storage slots. These slots are used to store construction tools such as jacks, positioning pins, screws, support rods, and support frames.

[0014] Preferably, the fourth reinforcing plate has mounting grooves at both ends, and the mounting grooves contain first rollers.

[0015] Both ends of the fourth reinforcing plate are equipped with connecting blocks that connect to the mounting frame, and the connecting blocks are equipped with second rollers.

[0016] With this invention, when the left and right inner molds are on the trolley, their bottom surfaces press against the first and second rollers, making it convenient for construction workers to use jacks to gather or separate the left and right inner molds, and allowing the left and right inner molds to slide easily on the trolley; thus reducing the friction between the left and right inner molds and the trolley.

[0017] Preferably, a support plate is provided above the reinforcement frame.

[0018] This utility model allows construction workers to stand on a trolley and install and remove support rods and support frames. Attached Figure Description
