Description

Technical Field

[0001] The present invention relates to the field of tunnel construction equipment, and particularly relates to a transfer device and a transfer method for a secondary lining trolley of a vehicle cross-passage Background Art

[0002] In a long tunnel, it is necessary to construct a vehicle cross-passage to ensure that vehicles can turn inside the tunnel in case of an emergency. The existing arch wall secondary lining trolley for vehicle cross-passages can only perform simple forward and backward movement functions. The process of transferring the secondary lining trolley during construction is as follows: ① Assemble the trolley directly opposite the vehicle cross-passage in the main tunnel of the tunnel, and then push the trolley forward parallel along the track into the vehicle cross-passage for lining construction; ② After the lining construction of the vehicle cross-passage is completed, push the trolley out of the vehicle passage through the track and into the main tunnel of the tunnel; ③ Since the track and the main tunnel of the tunnel are at an angle at this time, the trolley cannot move to the next vehicle cross-passage position through the track. Therefore, to avoid damaging the trolley components, it is necessary to disassemble the trolley, transport the components to the entrance of the next vehicle cross-passage, reassemble them, and finally repeat the previous work again.

[0003] Since the construction site is in the tunnel, it is inevitably restricted by the site, resulting in a long time required for a series of work such as transporting the trolley to the site for assembly, disassembly, transferring to the next vehicle cross-passage position for assembly, etc. At the same time, it also affects the normal time of other processes, consuming time, labor, and materials. In addition, for high-gas tunnels, during the process of disassembling and assembling the trolley, the frequency of welding and hot work in the tunnel is invisibly increased, that is, the safety risk of construction workers in the tunnel is increased. Summary of the Invention

[0004] The purpose of the present invention is to provide a transfer device and a transfer method for a secondary lining trolley of a vehicle cross-passage to solve the problem that in the secondary lining construction of a vehicle cross-passage, the trolley can only move forward and backward and is not convenient to be transferred to the next vehicle cross-passage position for construction. The transfer device can not only make the secondary lining trolley move forward and backward, but also quickly switch the walking direction of the trolley to left and right walking, which is beneficial to quickly transfer the secondary lining trolley from the current vehicle cross-passage to the next vehicle cross-passage during the secondary lining construction of the vehicle cross-passage.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0006] A transfer device for a secondary lining trolley of a vehicle cross-passage includes a walking frame and a driving motor arranged thereon. Walking wheels are arranged on the walking frame, and the driving motor is used to drive the walking wheels to walk along the secondary lining trolley track. A connecting block is also arranged on the walking frame. The connecting block is used to be connected with the vertical telescopic rod of the secondary lining trolley through a pin, and at least two pin holes are arranged on both the connecting block and the vertical telescopic rod, and the included angle between the pin holes is adapted to the angle of the vehicle cross-passage relative to the main tunnel of the tunnel.

[0007] In the transfer device of the present invention, the lower end of the vertical telescopic rod of the secondary lining trolley is connected by a pin. At least two pin holes are provided on both the connecting block and the vertical telescopic rod, and the included angle between the pin holes is adapted to the angle of the vehicle passage transverse tunnel relative to the main tunnel of the tunnel. When transferring the trolley, it is not necessary to disassemble the trolley. After the trolley is pushed out of the vehicle passage transverse tunnel and into the main tunnel of the tunnel, the pin is pulled out and the direction of the transfer device is rotated, and then the pin is inserted into another pin hole, so that the moving direction of the trolley can be quickly switched. Furthermore, the time for disassembling and reassembling the trolley can be reduced. After reaching the position of the next vehicle passage transverse tunnel, the walking direction of the trolley is quickly switched again to enter the next vehicle passage for the secondary lining construction of the arch wall. This transfer device can not only make the secondary lining trolley move forward and backward along the vehicle passage transverse tunnel, but also quickly switch the walking direction of the secondary lining trolley to move along the main tunnel of the tunnel, which is beneficial to quickly transfer the secondary lining trolley from the current vehicle passage transverse tunnel to the next vehicle passage transverse tunnel during the secondary lining construction of the vehicle passage transverse tunnel, without repeatedly disassembling and assembling the trolley, greatly saving the trolley transfer time, and being beneficial to improving the safety of tunnel construction.

[0008] As a preferred solution of the present invention, a spherical groove is provided on the connecting block, and the front part of the corresponding vertical telescopic rod is a ball head rod adapted to the spherical groove. By adopting the connection and cooperation of the spherical groove and the ball head rod, it is beneficial to enhance the connection force between the connecting block and the vertical telescopic rod of the secondary lining trolley, thereby improving the force on the pin connection and avoiding damage to the pin during use.

[0009] As a preferred solution of the present invention, the connecting block is divided into two parts based on the central plane of the spherical groove, and the two parts of the connecting block are connected into one body by bolts. Adopting the above solution is beneficial to the assembly connection between the ball head rod and the connecting block, and is also convenient for the processing of the spherical groove on the connecting block.

[0010] As a preferred solution of the present invention, the two pin holes on the connecting block are arranged on different cross-sections, and the two pin holes of the vertical telescopic rod are also arranged on two corresponding cross-sections. Adopting the above solution, on the one hand, it avoids reducing the strength of the cross-section due to the two pin holes being located on the same cross-section, and on the other hand, the two pin holes being located on different cross-sections can avoid the pins being inserted into the wrong positions.

[0011] As a preferred solution of the present invention, there are two walking wheels, namely a driving wheel and a driven wheel, and the driving wheel is connected to a driving motor.

[0012] As a preferred solution of the present invention, the driving wheel and the driven wheel are connected by chain or belt drive.

[0013] As a preferred solution of the present invention, the driving motor is an explosion-proof motor.

[0014] As a preferred embodiment of the present invention, the connecting block and the traveling frame are detachably connected.

[0015] A method for transferring the secondary lining trolley by using the above-mentioned transfer device for the secondary lining trolley in the vehicle passage cross tunnel includes the following steps:

[0016] Step 1: When the secondary lining trolley withdraws to the outside of the vehicle passage cross tunnel, jack up the trolley by the jack of the secondary lining trolley foundation, and pull out the pin between the connecting block and the vertical telescopic rod of the secondary lining trolley;

[0017] Step 2: Rotate the connecting block so that the traveling direction of the traveling wheels is parallel to the direction of the main tunnel, and then insert the pin into another pin hole on the connecting block and the vertical telescopic rod;

[0018] Step 3: Place the track under the traveling wheels, then adjust the vertical telescopic rod and the foundation jack to lower the transfer devices at the four corners of the trolley, and finally lower the foundation jack, thus completing the switching of the traveling direction of the secondary lining trolley;

[0019] Step 4: By cyclically using multiple tracks on each side, move the secondary lining trolley to the position where the next vehicle passage cross tunnel is located;

[0020] Step 5: Then switch the traveling direction of the transfer device in the same way so that the secondary lining trolley enters the vehicle passage cross tunnel for secondary lining construction.

[0021] Through steps 1 to 5 of this method, the traveling direction of the secondary lining trolley can be quickly switched from traveling along the vehicle passage cross tunnel direction to traveling along the main tunnel direction, which is beneficial for quickly transferring the secondary lining trolley from the current vehicle passage cross tunnel to the next vehicle passage cross tunnel during the secondary lining construction of the vehicle passage cross tunnel. Moreover, there is no need to repeatedly disassemble and assemble the trolley. The transfer operation of the secondary lining trolley is convenient, greatly saving the transfer time of the secondary lining trolley, and is beneficial to improving the construction safety of the gas tunnel.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] 1. In the present invention, the transfer device is connected to the lower end of the vertical telescopic rod of the secondary lining trolley by a pin. At least two pin holes are provided on both the connecting block and the vertical telescopic rod, and the included angle between the pin holes is adapted to the angle of the vehicle passage transverse tunnel relative to the main tunnel of the tunnel. When transferring the trolley, it is not necessary to disassemble the trolley. After the trolley is pushed out of the vehicle passage transverse tunnel and enters the main tunnel of the tunnel, the pin is pulled out, the direction of the transfer device is rotated, and then the pin is inserted into another pin hole, so that the moving direction of the trolley can be quickly switched. Furthermore, the time for disassembling and reassembling the trolley can be reduced. After reaching the position of the next vehicle passage transverse tunnel, the walking direction of the trolley is quickly switched again to enter the next vehicle passage for the construction of the arch wall secondary lining. This transfer device can not only make the secondary lining trolley advance and retreat along the vehicle passage transverse tunnel, but also quickly switch the walking direction of the secondary lining trolley to walk along the main tunnel of the tunnel, which is beneficial to quickly transfer the secondary lining trolley from the current vehicle passage transverse tunnel to the next vehicle passage transverse tunnel during the construction of the secondary lining of the vehicle passage transverse tunnel, without repeatedly disassembling and assembling the trolley, greatly saving the trolley transfer time and being beneficial to improving the safety of tunnel construction.

[0024] 2. In the present invention, by using the spherical groove and the ball head rod in connection and cooperation, it is beneficial to enhance the connection force between the connecting block and the vertical telescopic rod of the secondary lining trolley, thereby improving the force-bearing of the pin connection and avoiding damage to the pin during use.

[0025] 3. In the present invention, the connecting block is divided into two parts based on the central plane of the spherical groove, and the two parts of the connecting block are connected into one body by bolts. By adopting the above scheme, it is beneficial to the assembly connection between the ball head rod and the connecting block, and at the same time, it is also convenient for the processing of the spherical groove on the connecting block.

[0026] 4. In the present invention, the two pin holes on the connecting block are arranged on different cross-sections, and the two pin holes of the vertical telescopic rod are also arranged on the corresponding two cross-sections. By adopting the above scheme, on the one hand, it avoids reducing the strength of this cross-section due to the two pin holes being located in the same cross-section, and on the other hand, the two pin holes being located in different cross-sections can prevent the pin from being inserted into the wrong position.
