Description

Technical Field

[0001] The invention relates to the technical field of shield machine transportation, and in particular to a shield machine station-passing trolley and a shield machine station-passing method. Background Art

[0002] During the construction of underground projects such as urban subways and tunnels, the shield machine is a commonly used excavation equipment. In order to realize the rapid transfer of the shield machine from one working shaft to another, two methods are generally used: wheel-set walking method and roller sliding method. The wheel-set walking method realizes the movement of the shield machine through pre-laid tracks and walking wheels welded on both sides of the shield machine; while the roller sliding method uses jacking cylinders and rollers to achieve the translation of the shield machine. However, both methods have some obvious technical problems: (1) The amount of welding on the shield machine is large, which has a certain degree of impact on the strength and wear resistance of the main machine structure; (2) There is a lot of preliminary preparation work, the number of repeated uses of welding parts is small, and the welding parts are not properly handled, which is easy to damage the tunnel door sealing device, resulting in difficulty in sealing the tunnel door and even causing major losses; (3) After the shield machine is completed, the jacking cylinder, reaction force support, steel plate, etc. need to be manually transported with the help of a reverse chain, which requires a large number of people and takes a lot of time.

[0003] In order to solve the above problems, the prior art proposes a new way for shield machines to pass through stations, that is, using a station-passing trolley for passing through stations. At this time, the station-passing trolley can play a supporting and guiding role to reduce the amount of welding and preliminary preparation work, thereby improving the efficiency and safety of the shield machine passing through stations. For example, the prior art discloses a self-propelled shield machine station-passing trolley with a patent application number of CN201620737470.0. Its design purpose is to simplify the shield machine station-passing process through the station-passing trolley and improve work efficiency.

[0004] However, in the prior art (a self-propelled shield machine station-passing trolley with patent application number CN201620737470.0), the station-passing trolley can only move in a straight line along a fixed track, and during the shield body transfer process of the shield machine, it is also necessary to perform lateral movement when it reaches the standard section position. At this time, it is generally necessary to re-lay the track horizontally and install a jack cylinder horizontally to drive the trolley for lateral translation operation. The overall movement execution steps are relatively cumbersome, and the track trolley cannot be recycled, which increases construction costs and resource waste to a certain extent.

[0005] To this end, the present application specifically proposes a shield machine station-passing trolley and a shield machine station-passing method to solve the above-mentioned technical problems. Summary of the invention

[0006] The main purpose of the present invention is to provide a shield machine station-passing trolley that can conveniently lay tracks horizontally for translation and a shield machine station-passing method using the trolley.

[0007] In order to solve the above technical problems, the present invention provides a shield tunneling station-passing trolley, comprising a frame for supporting a shield body of a shield machine, the frame being slidably arranged on two sets of parallel station-passing tracks, and characterized in that it also comprises:

[0008] The walking mechanism is provided with multiple groups and distributed on both sides of the frame, and is used to drive the frame to move along the station track;

[0009] The movable connecting piece is arranged between the traveling mechanism and the frame, and is used to movably connect the traveling mechanism and the frame so that the traveling mechanism can be transferred between the parallel station-passing track and the transverse translation track.

[0010] Further, the walking mechanism includes a hydraulic jack, a track clamp and a reaction force support, the hydraulic jack and the track clamp are both installed on the reaction force support, and the end of the hydraulic jack is connected to the movable connecting piece;

[0011] The rail clamp is used to clamp the rail to fix the position of the reaction support;

[0012] The hydraulic jack pushes the frame to move on the track by telescoping.

[0013] Furthermore, the walking mechanism also includes an articulated component, and the hydraulic jack is installed on the reaction force support through the articulated component.

[0014] Furthermore, the lifting arm of the hydraulic jack is arranged obliquely, and one end of the hydraulic jack connected to the movable connecting piece is higher than the other end.

[0015] Furthermore, the walking mechanism also includes two groups of guide bars arranged at the bottom of the reaction force support, and the guide bars are located on both sides of the station passing track.

[0016] Furthermore, the movable connection member includes a universal joint member and a limit mounting plate installed on the frame, and the universal joint member is installed on the limit mounting plate for connecting the walking mechanism.

[0017] Furthermore, a plurality of movable wheel groups are arranged on both sides of the frame, and the movable wheels in the movable wheel groups are in contact with the tracks for supporting the frame.

[0018] Furthermore, the present invention also proposes a method for a shield machine to pass a station, using any of the above-mentioned shield machine to pass a station trolley, comprising the following steps:

[0019] S1. Lay the transit track and install the shield transit trolley on the transit track, then move the shield of the shield machine to the frame of the shield transit trolley;

[0020] S2. The mobile shield machine passing station trolley drives the shield body of the shield machine to pass the station;

[0021] S3. Using the hydraulic jacks set at an angle on both sides to provide thrust, the frame carrying the shield is lifted with the movable connector, the frame is lifted to a specified height, and then the track below the frame is removed;

[0022] S4. Lay the translation track that intersects the station track posture under the frame;

[0023] S5. The frame falls onto the translation track, and then the traveling mechanism is transferred to the horizontal translation track to complete the track switching operation of the shield tunneling trolley, and the traveling mechanism is used to move the frame carrying the shield body to the target area.

[0024] Furthermore, in the step S1, before the shield machine is put on the shield passing the station trolley, butter is applied on the track, the shield machine is pushed out of the steel sleeve, the position of the cutter disc is adjusted and the cutter disc is not allowed to be rotated after the adjustment, and the position of the side scraper and the passing station trolley track is staggered to prevent the side scraper from scratching the passing station trolley.

[0025] Furthermore, the specific operation steps of lifting in step S3 include:

[0026] S31. After the frame carrying the shield is lifted, the first pad is placed under the frame and the track under the frame is removed;

[0027] S32. Move the hydraulic jack to a vertical position and fix the bottom, continue to lift the trolley through the station, and then use the second pad to pad the bottom of the frame.

[0028] The beneficial effects of the present invention are embodied in:

[0029] 1.

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0045] In the embodiment, see Figures 1 to 5 .

[0046] like Figure 1 As shown, the present invention provides a shield station-passing trolley, which is slidably arranged on two sets of parallel station-passing tracks 4, wherein the shield station-passing trolley is welded by section steel and steel plate, has a size of 9000*4326mm, a height of 667mm, a guide rail center distance of 3540mm, and a wheel-track gauge of 3960mm, and the shield station-passing trolley specifically includes:

[0047] The frame 1 is slidably arranged on two sets of station-passing rails 4 and is used to support the shield body of the shield machine;

[0048] The walking mechanism 2 is provided in four groups and symmetrically distributed at the ends of both sides of the frame 1, and is used to drive the frame 1 to walk and move along the station-passing track 4;

[0049] The movable connecting member 3 is installed at the end of the walking mechanism 2 and connected to the frame 1, and is used for movably adjusting the installation posture of the walking mechanism 2 on the frame 1 to adapt to the lateral translation track.

[0050] During specific use, by using the traveling mechanism 2 and the movable connecting part 3 on the frame 1, the traveling mechanism 2 can be used to drive the frame 1 to move along the station track 4. At the same time, the frame 1 can be lifted to facilitate the horizontal laying of pads and tracks, and the traveling mechanism 2 can be turned to be installed on the horizontal translation track to perform translation operations on the frame 1.

[0051] In addition, it should be noted that when the passing trolley is fixed on the track, H-shaped steel can be used to reinforce the base around the track. When the shield is put up, 4 H20 steel diagonal braces are set in front and behind the trolley, and 6 H20 steel diagonal braces are set on the left and right sides to prevent the trolley from sliding during the shield raising process. All H20 steel diagonal braces should be removed after the shield is raised.

[0052] Among them reference Figure 2 and Figure 3 The walking mechanism 2 includes a hydraulic jack 21, a track clamp 22 and a reaction force support 23. The hydraulic jack 21 and the track clamp 22 are both installed on the reaction force support 23. The end of the hydraulic jack 21 is connected to the movable connecting piece 3. The track clamp 22 is pneumatically controlled to clamp on the track to fix the position of the reaction force support 23. The hydraulic jack 21 is hydraulically controlled to realize the jacking and extension operation, and finally realizes the pushing of the frame to move on the station track 4.

[0053] In the specific use process, the moving process specifically includes:

[0054] (1) Before the shield machine goes up to the station trolley, apply butter on the station track 4, push the shield machine out of the steel sleeve, adjust the cutterhead position, stagger the position of the scraper and the station track 4 of the station trolley to prevent the scraper from scratching the station trolley. After the adjustment, the cutterhead is not allowed to rotate. Communication is maintained during the process. The shield machine drives onto the station trolley according to the guidance. Here, the shield machine is mounted by assembling the lower negative ring segments. After assembly, the shield machine is pushed forward by the shield excavation cylinder. After the shield machine is mounted on the station trolley, the connecting bridge connecting the shield machine and the shield body is dismantled;

[0055] (2) The shield body passes through the station by sliding the station trolley on the station track 4 pre-laid on the station floor. The thrust provided by two 200t hydraulic jacks 21 at one end of the frame 1 overcomes the gravity of the shield machine and the station trolley and the friction between the station trolley and the station track 4, and pushes the station trolley and the shield machine forward. For details, refer to Figure 4 As shown, when the shield body of the shield machine moves to the frame 1, the two sets of walking mechanisms 2 at one end of the frame 1 are driven and clamped by the track clamp 22 pneumatically controlled to fix the reaction support 23 and install it on the station track 4, and then the hydraulic jack 21 is lifted to drive the frame 1 to carry the shield body of the shield machine and move along the station track 4. At this time, butter is applied on the track surface of the station track 4 before installation. The total weight of the shield machine head, screw machine, assembly machine, station trolley, etc. is generally within 400t. Under normal circumstances, the steel The friction coefficient between steel and steel is 0.1-0.15, and the friction coefficient with lubrication is 0.05-0.1. The maximum friction coefficient is 0.15 when calculating, and the maximum dynamic friction resistance is: F=μN (the maximum thrust of shield machine movement is μ=0.15)=0.15×400=60t. Therefore, the thrust provided by two 200t hydraulic jacks 21 and the supporting hydraulic station can fully meet the power requirements in translation. A single reaction clamp can meet the 200t reaction force, so the reaction support meets the translation requirements.

[0056] Therefore, by setting up the walking mechanism 2 and utilizing the coordinated use of the hydraulic jack 21 and the track clamp 22, the frame carrying the shield body of the shield machine can be driven to move along the length direction of the station track 4, thereby completing the stable operation of the shield body of the shield machine between the two channel shafts. The structure is simple, no extra welding steps are required, and it is easy to use.

[0057] In addition, it is necessary to explain that due to the long length of the station, the stroke of the 200t jack is 80cm, and the elongation of the jack is limited. It is impossible to push the entire shield machine to the starting shaft position at one time. It is necessary to repeatedly cycle the pneumatically controlled track clamp 22 to clamp the reaction force support 23, the hydraulic jack 21 to lift and push the frame 1 to move, the track clamp 22 to release, and use the hydraulic jack 21 to retract to drive the reaction force support 23 to move forward, so as to complete the shield machine passing the station construction.

[0058] In addition, the traveling mechanism 2 further comprises an articulated component 24 , and the hydraulic jack 21 is mounted on the reaction force support 23 via the articulated component 24 .

[0059] It should be noted that the lifting arm of the hydraulic jack 21 is tilted at this time, so the two ends of the hydraulic jack 21 are not parallel, the lifting arm of the hydraulic jack 21 close to the frame 1 is slightly higher than the other end, and the slope is above 30°, generally set to 40°.

[0060] At this time, in the specific implementation process, refer to Figure 5 Since the hydraulic jack 21 is installed on the frame 1 through the movable connecting piece 3, the frame 1 can be lifted up by using four groups of hydraulic jacks 21 in conjunction with the hinge 24 during the synchronous force application of the four groups of hydraulic jacks 21. At this time, it is convenient to lay steel pads at the bottom of the frame 1 to achieve stable support for the frame 1 and the shield body of the shield machine. After the steel pads are installed to stably support the frame 1 and the shield body of the shield machine, the terminal station-passing track 4 is removed, and a transverse translation track is laid. The walking mechanism 2 is turned and installed on the transverse translation track. The hydraulic jack 21 is subjected to force again. After the steel pads are removed, the hydraulic jack 21 can be driven to retract and the frame 1 can be lowered to the transverse translation track. At this time, the walking mechanism 2 can continue to be used to achieve lateral movement of the frame 1, thereby realizing the terminal operation of the shield passing the station.

[0061] In summary, by setting four groups of walking mechanisms 2 and symmetrically arranging them at the ends of both sides of the frame 1, the hydraulic jack 21 can be used in conjunction with the hinge 24 and the movable connecting member 3 to control the lifting of the frame 1 carrying the shield body of the shield machine, so as to facilitate the removal of the station track 4 at the bottom of the frame 1 and the synchronous transverse laying of pads and translation tracks, which is convenient for the lateral translation of the frame 1. At the same time, the walking mechanism is connected by setting the movable connecting member 3. When the frame 1 is located on the transverse translation track, the walking mechanism 2 can be turned and reloaded on the transverse translation track using the movable connecting member 3, so as to further perform the translation operation of the frame 1. The structure is simple, the use and installation of redundant components are reduced, and it is convenient to use.

[0062] In addition, it should be supplemented that the walking mechanism 2 also includes two groups of guide bars 25 arranged at the bottom of the reaction force support 23, and the guide bars 25 are located on both sides of the track.

[0063] The guide strip 25 can be used to improve the force stability of the 200t hydraulic jack 21 on the reaction support 23 and ensure the installation stability of the track clamp 22 when it is in a released state.

[0064] In a specific embodiment, if Figure 2 and Figure 3As shown, the movable connecting member 3 includes a universal joint 31 and a limiting mounting plate 32 mounted on the frame 1 , and the universal joint 31 is mounted on the limiting mounting plate 32 for connecting to the walking mechanism 2 .

[0065] In a specific embodiment, a plurality of movable wheel groups 11 are symmetrically arranged on both sides of the movable frame 1 in contact with the station track 4. The movable wheel group 11 is composed of two groups of movable wheels. The movable wheels in the movable wheel group 11 are used to flexibly adjust the posture so as to fit and slide on the lateral translation track.

[0066] Specifically, each side of the station-passing trolley has 12 wheels, and the transverse translation track is placed in the middle of each set of movable wheels 11 of the station-passing trolley, and the track is fixed by planting steel bars.

[0067] At this point, it can be supplemented that during the lifting and movement of the frame 1, when the trolley is 5 cm above the track, the lifting is stopped, the longitudinal station track 4 is removed, and the track is inserted horizontally and translated to be distributed between the wheels of the station trolley.

[0068] In addition, based on the above-mentioned shield machine station-passing trolley, the present invention also proposes a shield machine station-passing method, comprising the following steps:

[0069] S1. After the shield tunnel section of the tunnel is penetrated, the shield machine is excavated to the steel sleeve, and the shield machine passes the station by the above-mentioned shield station trolley. The station trolley is divided into a frame 1 and a walking mechanism 2. The frame 1 is welded by steel and steel plates. The central axis of the shield station trolley should be installed strictly in accordance with the shield receiving posture to ensure that the shield is smoothly mounted. The station track 4 is laid for movement. The shield station trolley is installed on the track. When the shield station trolley is fixed on the track, the track is reinforced with H-shaped steel around. Four H20 steel diagonal braces are set at the front and rear of the shield station trolley, and six H20 steel diagonal braces are set on the left and right to prevent the shield station trolley from sliding when the shield is mounted. Then the shield machine is moved to the frame 1 of the shield station trolley. After the mounting is completed, all H20 steel diagonal braces are removed;

[0070] At this point, it is also necessary to explain that before the shield machine is put on the shield station trolley, butter is applied on the track, the shield machine is pushed out of the steel sleeve, the cutter head position is adjusted and the cutter head is not allowed to be rotated after adjustment, and the side scraper and the shield station trolley track position are staggered to prevent the side scraper from scratching the shield station trolley;

[0071] S2. Before the shield machine passes the standard section, the station clearance size needs to be reviewed, and the line needs to be laid out in advance according to the design center line of the station. The track needs to be laid according to the center line of the station. The shield body needs to pass the station on the track using the shield station trolley. Two sets of hydraulic jacks 21 on one side are used to provide thrust to overcome the gravity of the shield machine and the shield station trolley and the friction between the shield station trolley and the track, and push the shield station trolley and the shield machine forward. The jack stroke is 80cm, and the elongation of the jack is limited. The shield machine cannot be pushed to the starting shaft position at one time. The jack needs to be installed and positioned repeatedly to complete the shield machine station construction.

[0072] S3. Before the shield machine is lifted, the center of gravity is calculated according to the weight of the shield machine, and the hydraulic jacks 21 arranged obliquely on both sides are used to provide thrust. The shield machine-carrying trolley can be lifted in cooperation with the movable connecting piece 3. The shield machine-carrying trolley is lifted to the same height as the standard section and then fixed. A transverse translation track is installed corresponding to the standard section passing position. The translation track has a specified height and is used to use the traveling mechanism 2 again to push the shield machine-carrying trolley into the initial area of ​​the standard section.

[0073] The specific steps for fixing after lifting include:

[0074] S31. After the shield tunneling trolley carrying the shield machine is lifted by 50 cm, the steel box girder is inserted as the first cushion block under the shield tunneling trolley according to the calculated center of gravity position, and the last section of the tunneling track 4 is withdrawn;

[0075] S32. Move the hydraulic jack 21 to a vertical position and fix the bottom, continue to lift the shield tunneling trolley for 500 mm, then stop lifting, and use 450 mm H-shaped steel with ribs to weld a steel box girder as the second pad under the shield tunneling trolley (the ribs are welded from 20 mm steel plates, with a spacing of 300 mm);

[0076] S33. Determine whether the height meets the requirements according to the actual engineering requirements. If not, the H-shaped steel and the shield station trolley can be fixed together and then continue to be lifted. After being lifted to the preset height, the lifting is stopped and the iron piers welded with seamless steel pipes are placed under the steel box beam, with 6 pads on each side, and are connected as a whole with channel steel for reinforcement and fixation;

[0077] S4. Lay the translation track that intersects with the station-passing track 4 under the frame 1, the frame 1 falls onto the translation track, and then transfer the traveling mechanism 2 to the horizontal translation track to complete the track switching operation of the shield station-passing trolley. The shield station-passing trolley is flush with the standard section, and use the traveling mechanism 2 to move the frame carrying the shield body to the target area, and finally move the shield machine off the frame to complete the station-passing operation of the shield machine.

[0078] In summary, this method adopts an improved shield station-passing trolley, which can reduce the frequent installation of jacks compared with the existing technology, streamline the structure and improve the efficiency of shield trolley track changing, thereby improving the shield station-passing speed and quality and facilitating use.
