Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a large longitudinal slope second lining trolley construction walking system. Background Art

[0002] In tunnel construction, secondary lining is one of the important links in tunnel construction. The secondary lining trolley, full name of which is the tunnel secondary lining trolley, is an important construction equipment to complete this link. It is usually composed of a frame, formwork, hydraulic system, travel system and other parts. The frame, as the main structure, provides support for the entire equipment, and the formwork is in direct contact with the concrete to ensure that the surface quality of the poured concrete is good.

[0003] After searching, the Chinese patent number CN219262384U discloses a new self-propelled maintenance trolley for tunnel secondary lining construction, including a support frame, a travel guide rail symmetrically arranged on the lower side of the support frame, a travel wheel arranged on the inner side of the travel guide rail, a screw guide rail symmetrically arranged on the upper side of the support frame, and a support arc arranged on the upper side of the screw guide rail. The utility model provides a screw guide rail, a servo motor, a support arc, a water spray elbow and a nozzle, so that when the tunnel secondary lining construction maintenance trolley is used, after the mobile trolley moves to a position, the servo motor drives the support arc to move horizontally through the screw guide rail, so that the nozzle can evenly spray water on the secondary lining wall for maintenance.

[0004] After searching, the Chinese patent number CN207598258U discloses a tunnel secondary lining repair trolley, which belongs to the field of trolleys and aims to provide a tunnel secondary lining repair trolley that is easy to move to reduce the human resource investment during the movement. It includes a trolley body, running wheels installed at the lower end of the trolley body, and at least two electric hoists arranged between the trolley body and the second lining trolley in front of it; one end of the electric hoist is hung on the second lining trolley, and the other end is hung on the trolley body. This utility model facilitates the pushing or pulling of the repair trolley by installing running wheels at the lower end of the trolley body; by arranging an electric hoist between the trolley body and the second lining trolley in front of it to pull the trolley body close to the second lining trolley, the trolley body can also follow the movement of the second lining trolley.

[0005] In the above patent, in the construction of inclined shafts, especially in the construction of inclined shafts with large longitudinal slopes, the traditional tunnel second lining trolley based on the second lining construction adopts a motor-driven wheel type, which requires manual laying of sleepers and rails, consumes a lot of labor and has a large material loss. In the construction of the inverted arch surface with a large longitudinal slope, an additional anti-slip device is required, the walking motor needs to be equipped with a brake device, and the track needs to be fixed. The trolley travels slowly and is prone to slipping. While the construction progress is slow, there are also certain construction safety risks. Based on this, the present invention designs a large longitudinal slope second lining trolley construction walking system to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide a large longitudinal slope secondary lining trolley construction walking system, which solves the problems of large manpower and material consumption and slow construction in the background technology.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] A large longitudinal slope secondary lining trolley construction walking system, comprising:

[0009] A running body, the running body comprising a lower longitudinal beam, used for supporting and connecting the top and bottom components;

[0010] The driving mechanism is installed at the bottom of the running body and is used for the normal operation of the construction walking system. The driving mechanism includes a translation component and a lifting component. The translation component is installed at the four corners of the running body and is used for the vertical movement of the running body. The lifting component is installed at the bottom of the running body and is used for the horizontal movement of the running body.

[0011] Preferably, the translation assembly comprises a translation assembly installed on one side of the operating body, a translation cylinder is installed on one side of the translation assembly, and the translation cylinders are arranged in four groups and distributed in a matrix array.

[0012] Preferably, the lifting assembly includes lifting cylinders installed at the four corners of the operating body, and the lifting cylinders are distributed in a matrix array and are used for stable lifting of the operating body.

[0013] Preferably, the driving mechanism further comprises a walking base installed at the bottom of the lower longitudinal beam, the walking bases are connected by support rods, the support rods are connected to the lower longitudinal beam via a walking assembly and the driving force is generated by the walking assembly.

[0014] Preferably, the walking assembly includes a fixed seat installed on the top of the support rod and a connecting seat at the bottom of the lower longitudinal beam, a walking cylinder is hinged in the inner cavity of the connecting seat and the output end of the walking cylinder is hinged in the inner cavity of the fixed seat, the walking cylinder is provided with two front and rear groups, and a limiting assembly is also installed at the bottom of the walking base.

[0015] From the above technical solution, we can know that the core of the system lies in its driving mechanism, which cleverly combines the translation components installed at the four corners of the trolley with the lifting components located at the bottom. The translation components ensure the stable movement of the trolley in the vertical direction through the matrix-distributed translation cylinders; while the lifting components use the lifting cylinders installed at the four corners of the running body to achieve the horizontal movement and lifting operation of the trolley. This design not only improves the flexibility of the trolley, but also greatly enhances its adaptability in complex terrain and longitudinal slope conditions.

[0016] Preferably, the limiting assembly includes an anti-skid steel bar installed at the bottom of the walking base to enhance walking safety on a road surface with a large longitudinal slope and ensure that the maximum usable slope can reach 20%.

[0017] Preferably, locking mechanisms are installed inside the translation assembly and the lifting assembly, and the locking mechanisms include hydraulic locks for locking the cylinder when it is not working to prevent accidental movement; the translation assembly and the lifting assembly are both operated by the hydraulic station control valve to achieve the lifting, moving and direction adjustment of the trolley.

[0018] Preferably, the walking system has a hydraulic cylinder under force all the time during the walking process to prevent slipping during walking.

[0019] Preferably, a large longitudinal slope secondary lining trolley construction walking system provides the following method for use:

[0020] Step 1: After the four-corner lifting components of the trolley are started, the travel cylinder at the bottom of the lower longitudinal beam and the travel base are lifted off the ground, and the control valve on the hydraulic station is operated to fully retract the travel cylinder. At this time, the trolley is in a waiting state;

[0021] Step 2: Operate the control valve of the lifting cylinder to retract the lifting cylinder and the travel assembly lands;

[0022] Step 3: Continue to retract the lifting cylinder so that the translation assembly of the translation component leaves the ground;

[0023] Step 4: Operate the travel cylinder control valve, the travel cylinder slowly extends, and the trolley can move forward;

[0024] Step 5: Repeat step 1 to step 2 until the trolley moves to the working position;

[0025] Step 6: When the trolley is moving, use the translation cylinder to adjust the overall direction of the trolley according to the actual situation;

[0026] Step 7: After the trolley is in place, use the translation cylinder to adjust the center line of the trolley to coincide with the center line of the tunnel.

[0027] Through the above technical solution, it can be seen that during the walking process, the system fully utilizes the driving force of the hydraulic cylinder and locks it through the hydraulic lock when the cylinder is not working, thereby ensuring the stability and safety of the trolley. At the same time, the anti-skid steel strips installed at the bottom of the walking base further enhance the friction coefficient of the trolley on the road surface with a large longitudinal slope, effectively preventing the occurrence of slipping. In addition, the system is also equipped with a translation cylinder, so that the trolley can flexibly adjust its direction according to the actual situation during the walking process to ensure the construction accuracy.

[0028] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0029] 1. The present invention uses a conventional motor-driven wheeled double-lining trolley that requires manual laying of sleepers and rails, which not only consumes a lot of labor but also results in large material losses. The present invention uses an innovative drive mechanism design, especially the combination of a walking assembly and a lifting assembly, to achieve autonomous walking and lifting of the trolley without the need to lay tracks, thereby greatly reducing the use of labor and materials and lowering construction costs.

[0030] 2. According to the present invention, in the construction of a large longitudinal slope arch surface, a traditional trolley needs to be additionally provided with an anti-skid device, and the travel motor needs to be equipped with a braking device, and the track also needs to be fixed, resulting in a slow travel speed of the trolley and prone to slipping. The present invention effectively prevents the slipping of the trolley through the continuous force of the hydraulic cylinder and the design of anti-skid steel bars, ensures the stable travel of the trolley on the large longitudinal slope road surface, improves construction efficiency, and reduces construction safety risks.

[0031] 3. The present invention, the translation assembly and the lifting assembly of the present invention are operated by the hydraulic station control valve, and a locking mechanism is installed inside, which can lock the oil cylinder when it is not working to prevent accidental movement. This design not only improves the stability and controllability of the system, but also enables the trolley to stably walk on a large longitudinal slope road with a maximum use slope of 20%, and can adjust the direction according to the actual situation, ensuring the construction accuracy and progress.

[0048] See also Figure 1-Figure 6 In the embodiment of the present invention, the driving mechanism 2 also includes a walking base 201 installed at the bottom of the lower longitudinal beam 101, and a support rod 202 is installed between the walking bases 201 to connect them. The support rod 202 and the lower longitudinal beam 101 are connected through a walking component 5, and the driving force is generated by the walking component 5.

[0049] The walking component 5 includes a fixed seat 501 installed on the top of the support rod 202 and a connecting seat 502 at the bottom of the lower longitudinal beam 101.

[0053] The locking mechanism 7 installed inside the translation assembly 3 and the lifting assembly 4 includes a hydraulic lock 701, which is used to lock the cylinder when it is not working to prevent accidental movement, thereby improving the safety and stability of the system.

[0054] Embodiment 3;

[0055] See also Figure 1-Figure 6 In the embodiment of the present invention, a locking mechanism 7 is installed inside the translation assembly 3 and the lifting assembly 4. The locking mechanism 7 includes a hydraulic lock 701, which is used to lock the cylinder when it is not working to prevent accidental movement; the translation assembly 3 and the lifting assembly 4 are both operated by the hydraulic station control valve to realize the lifting, moving and direction adjustment of the trolley.

[0056] The travel system is always under pressure from the hydraulic cylinder during the travel process to prevent slipping.

[0057] A large longitudinal slope secondary lining trolley construction walking system provides the following methods for use:

[0058] Step 1: After the four-corner lifting assembly 4 of the trolley is started, the travel cylinder 503 at the bottom of the lower longitudinal beam 101 and the travel base 201 are lifted off the ground, and the control valve on the hydraulic station is operated to fully retract the travel cylinder 503. At this time, the travel of the trolley is in a waiting state;

[0059] Step 2: operate the control valve of the lifting cylinder 401 to retract the lifting cylinder 401 and the walking assembly 5 falls to the ground;

[0060] Step 3: Continue to retract the lifting cylinder 401 so that the translation assembly 301 of the translation component 3 leaves the ground;

[0061] Step 4: Operate the control valve of the travel cylinder 503, and the travel cylinder 503 slowly extends, and the trolley can move forward at this time;

[0062] Step 5: Repeat steps 2 to 4 until the trolley moves to the working position;

[0063] Step 6: During the movement of the trolley, according to the actual situation, the translation cylinder 302 is appropriately used to adjust the overall direction of the trolley;

[0064] Step 7: After the trolley is in place, use the translation cylinder 302 to adjust the center line of the trolley to coincide with the center line of the tunnel.

[0065] The working principle of the embodiment of the present invention is:

[0066] Startup and preparation: When the trolley needs to be moved, first start the lifting cylinder 401 of the lifting assembly 4 to raise the four corners of the trolley, and the travel cylinder 503 at the bottom of the lower longitudinal beam 101 and the travel base 201 are off the ground. Then, operate the control valve on the hydraulic station to fully retract the travel cylinder 503, and the trolley enters the waiting state.

[0067] Walking process: operate the control valve of the lifting cylinder 401, retract the lifting cylinder 401, and make the walking assembly 5 fall to the ground. Continue to retract the lifting cylinder 401 to make the translation assembly 301 of the translation assembly 3 leave the ground. At this time, operate the control valve of the travel cylinder 503, and the travel cylinder 503 slowly extends to push the travel base 201 and the entire trolley forward. During the walking process, since the hydraulic cylinder is always under force and the anti-slip steel strip 601 provides additional friction, the system can effectively prevent the occurrence of slipping.

[0068] Direction adjustment and positioning: During the movement of the trolley, the overall direction of the trolley can be adjusted according to the actual situation by operating the translation cylinder 302. When the trolley reaches the predetermined working position, the translation cylinder 302 is used to further adjust the center line of the trolley to coincide with the center line of the tunnel to ensure construction accuracy.

[0069] Working principle: In terms of structural composition, the walking system is mainly composed of the operating body 1, the driving mechanism 2 and the translation assembly 3, the lifting assembly 4, the walking assembly 5 and other key parts. The operating body 1 serves as the bearing frame of the entire system. The top and bottom components are firmly connected through the lower longitudinal beam 101, providing a solid foundation for the operation of the trolley. The driving mechanism 2 is installed at the bottom of the operating body 1 and is the power source of the system. Among them, the translation assembly 3 includes a translation assembly 301 and a translation cylinder 302 installed at the four corners of the trolley, which are responsible for the stable movement of the trolley in the vertical direction; the lifting assembly 4 realizes the horizontal movement and lifting operation of the trolley through the lifting cylinder 401 installed at the four corners of the operating body 1. In addition, the walking assembly 5 is composed of a fixed seat 501 installed on the top of the support rod 202, a connecting seat 502 at the bottom of the lower longitudinal beam 101, and a walking cylinder 503 hinged therebetween, which provides the trolley with the power to move forward.

[0070] In terms of the operation process, the walking system realizes the movement and positioning of the trolley through a series of orderly steps. First, start the lifting cylinder 401 of the lifting assembly 4 to lift the four corners of the trolley, lift the walking cylinder 503 and the walking base 201 off the ground, and completely retract the walking cylinder 503 to put the trolley into a waiting state. Next, retract the lifting cylinder 401 to make the walking assembly 5 fall to the ground, and continue to retract the lifting cylinder 401 to make the translation assembly 301 of the translation assembly 3 leave the ground. At this time, operate the control valve of the walking cylinder 503 to slowly extend it, pushing the walking base 201 and the entire trolley forward. During the walking process, the overall direction of the trolley can be adjusted by operating the translation cylinder 302 according to the actual situation. When the trolley reaches the predetermined working position, use the translation cylinder 302 again to adjust the center line of the trolley to coincide with the center line of the tunnel to ensure construction accuracy.

[0071] In terms of safety, the walking system adopts a number of innovative designs. First, a locking mechanism 7 is installed inside the translation component 3 and the lifting component 4, including a hydraulic lock 701, which is used to lock the cylinder when it is not working to prevent accidental movement, thereby improving the safety and stability of the system. Secondly, a limit assembly 6 is installed at the bottom of the walking base 201, which is mainly composed of anti-skid steel strips 601. These anti-skid steel strips 601 enhance the walking safety of the trolley on the road surface with a large longitudinal slope, ensuring that the maximum use slope can reach 20% without safety accidents such as slipping. In addition, the walking system is always under force in the hydraulic cylinder during the walking process, which further prevents the occurrence of slipping.

[0072] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations may be made to the embodiments without departing from the principles and spirit thereof, and the scope of the present invention is defined by the appended claims and their equivalents.
