[0027] Next, the pipe gallery box-shaped external mold lifting and transporting device of the present exemplary embodiment will be further described.

[0028] In some embodiments of the present application, the above-mentioned transport vehicle body 2 includes a bottom frame 21, a triangular support 22, and a load-bearing I-beam 23. The triangular support 22 is arranged on the top of the bottom frame 21. Both the triangular support 22 and the bottom frame 21 are welded by rectangular steel pipes. The triangular support 22 is welded into a triangular stable structure, forming a sheet-frame box-type stable support with the bottom frame 21. The above-mentioned guide wheel set 3 is arranged at the bottom of the bottom frame 21, and the guide wheels are rollingly connected to the transport track 1, so that the transport vehicle body 2 can move horizontally in a straight line along the transport track 1. The above-mentioned load-bearing I-beam 23 is connected to the top of the triangular support 22. The load-bearing I-beam 23 serves as a main load-bearing rod and is welded to the triangular support 22 at the bottom, and is used to carry the box-shaped outer molds 7 on both sides. Through the above structural design, the transport vehicle body 2 combines the characteristics of the back groove environment, utilizes the narrow space at the top of the pipe gallery, realizes the vertical lifting and horizontal transportation of the box-shaped outer mold 7, and overcomes the problem that traditional large cranes cannot vertically lift and transport in the narrow space of the pipe gallery.

[0029] It should be noted that the driving of the above-mentioned transport vehicle body 2 adopts any linear driving mechanism in the prior art that can drive the vehicle body to run on the track, and can be remotely controlled by remote control. For example, the motor drives the guide wheel set 3 to rotate to realize the operation on the transport track 1, and specific details are not described herein.

[0030] As a preferred implementation manner, the above-mentioned telescopic member 4 is correspondingly located above the installed box-shaped outer mold 7, and the distance from the center points of the two telescopic members 4 to the side wall of the pipe gallery main body is greater than the distance from the center point of the box-shaped outer mold 7 to the side wall of the pipe gallery main body. Through the above design, when the transport vehicle body 2 lifts the box-shaped outer mold 7, the box-shaped outer mold 7 can be separated from the outer wall of the pipe gallery after being lifted.

[0031] As a preferred implementation manner, there are two above-mentioned transport tracks 1, and the two transport tracks 1 are arranged oppositely. The transport tracks 1 are used to be installed on the top of the pipe gallery to ensure the straight-line walking of the transport vehicle body 2. There are two groups of the above-mentioned guide wheel sets 3, and the two groups of guide wheel sets 3 are respectively arranged at both ends of the bottom of the bottom frame 21. The two groups of guide wheel sets 3 are respectively rollingly connected to the two transport tracks 1. Each group of guide wheel sets 3 includes two guide wheels, and there are a total of four guide wheels on both sides, so that the transport vehicle body 2 can walk stably on the transport track 1.

[0032] As a preferred implementation manner, there are multiple groups of the above-mentioned triangular supports 22, and the multiple groups of triangular supports 22 are arranged at intervals on the top of the bottom frame 21. Multiple groups of triangular supports 22 are welded between the bottom frame 21 and the load-bearing I-beam 23 to play a role in stably supporting the load-bearing I-beam 23.

[0033] As a preferred implementation, the telescopic member 4 is a hydraulic cylinder, and the driving member 6 is a hydraulic station, which is connected to the hydraulic cylinder. The hydraulic cylinder is a 30-ton hydraulic cylinder, and the power of the hydraulic cylinder is provided by the hydraulic station. Four steel wire rope hooks 5 are arranged at the bottom of the hydraulic cylinder. When the hydraulic cylinder extends, the staff hangs the steel wire rope hook 5 at the bottom of the hydraulic cylinder on the inner sling of the box-shaped external mold 7, and the hydraulic cylinder contracts to lift the box-shaped external mold 7. Through the above design, the transport vehicle body 2 has scalability, lifting function, is easy to use, has strong stability, and is easy to operate by the staff. It should be noted that the distance between the steel support on the top of the pipe gallery and the top of the pipe gallery main body is about one and a half meters, which has enough operating space for the staff to hang the steel wire rope hook 5 on the box-shaped external mold 7.

[0034] The working principle of this application: The transport track 1 is laid at the preset installation position on the top of the pipe gallery. The specific operation is as follows: Before laying the transport track 1 on the top of the pipe gallery, first perform surface cleaning, remove debris such as gravel and garbage to ensure that there is no obstacle when the transport vehicle body 2 moves forward, and install the track according to the provided track placement position dimensions. Among them, the above preset installation position is located at: The telescopic members 4 at both ends of the transport vehicle body 2 after installation correspond to a designated distance offset from the center position of the box-shaped external mold 7 towards the support side. That is, the installation position is located at a position where the box-shaped external mold 7 is separated from the outer wall of the pipe gallery after lifting, which is convenient for quickly horizontally transporting the box-shaped external mold 7 out and avoiding collisions with the outer wall of the pipe gallery and causing obstacles to it. In a specific embodiment, after the transport vehicle body 2 is installed, the center position of the hydraulic cylinder is offset from the center position of the box-shaped external mold 7 towards the support side, with a distance of about 10 cm. Refer to Figures 2 - 4 .

[0035] Lift the transport vehicle body 2 onto the transport track 1 and control the transport vehicle body 2 to move to the position of the box-shaped external mold 7 to be demolished; the specific operation is as follows: Through the vehicle lifting structure, lift the horizontal transport vehicle to the construction site, and when lifting, align the groove of the guide wheel with the upper plane of the transport track 1 and place it.

[0036] Control the telescopic movement of the telescopic member 4 through the driving member 6, connect the steel wire rope hook 5 to the sling of the box-shaped external mold 7 and lift the box-shaped external mold 7; the specific operation is as follows: Among them, the telescopic member 4 is a hydraulic cylinder, and the driving member 6 is a hydraulic station; Connect the hydraulic station to 220V power supply and conduct an oil supply test on the hydraulic cylinder to ensure that during the telescopic movement of the hydraulic cylinder, the cylinder body is full of oil and no gas, the telescopic stop is smooth and there is no displacement, ensuring construction safety; Drive the hydraulic cylinder to extend through the hydraulic station, and connect the steel wire rope hook 5 to the sling of the box-shaped external mold 7; Drive the hydraulic cylinders at both ends of the transport vehicle body 2 to contract through the hydraulic station, lift the box-shaped external mold 7, and through the center offset effect, the box-shaped external mold 7 is automatically separated from the pipe gallery wall after being lifted. Refer to Figure 5 .

[0037] Finally, the transport vehicle 2 is controlled to move to the ejection port, and the box-shaped outer mold 7 is lifted out. The specific operation is as follows: after the box-shaped outer mold 7 is lifted, the horizontal transport vehicle 2 is transported in a straight line on the transport track 1, and the box-shaped outer mold 7 is transported to the ejection position. The truck crane lifts out the box-shaped mold and transfers it to the next location for re-construction.

[0038] Beneficial effects:

[0039] By installing 30-ton hydraulic cylinders on both sides of the load-bearing I-beam 23, the hydraulic cylinders are powered by a hydraulic station, and four steel rope hooks are arranged at the bottom of the hydraulic cylinders. When the hydraulic cylinders are extended, the steel rope hooks at the bottom of the hydraulic cylinders are hung on the inner lifting rings of the box-type outer mold 7, and the hydraulic cylinders are contracted to lift the box-type outer mold 7. Because the center position of the hydraulic cylinder connected to the top of the "I"-beam is 10 cm away from the center of the box-type outer mold 7 in the return groove, the box-type outer mold 7 is separated from the outer wall of the pipe gallery after being lifted. This device is easy to use, has strong stability, and is easy for staff to operate.

[0040] Tracks are laid on the top of the tunnel, and four track guide wheels are installed on both sides of the bottom of the horizontal transport vehicle to achieve linear movement of the box-shaped outer mold 7, which saves labor and greatly improves construction efficiency.

[0041] The structural frame adopts a triangular support 22 structure as the frame support fulcrum, and is transported by walking on the guide rail. The horizontal transport vehicle is transported in a shoulder pole manner. A box-shaped outer mold 7 is hoisted on each side, with equal weight and stable walking.

[0042] Green construction, no pollution, stable and reliable construction methods.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
