Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction equipment, in particular to a tunnel operation trolley. Background Art

[0002] During the construction of railway tunnels and the treatment of railway tunnel defects, tunnel operation trolleys are needed to assist in construction and treatment. At present, most of these tunnel operation trolleys are welded according to specific tunnel outline dimensions using angle steel, channel steel, I-beam and other profiles. However, when treating railway tunnel defects, the response speed must be fast and the normal passage of the railway must not be affected as much as possible. However, the above-mentioned tunnel operation trolleys are too bulky, which makes movement inconvenient, and work efficiency is forced to be reduced, which prolongs the tunnel treatment cycle and cannot meet the needs of rapid treatment. Furthermore, because the above-mentioned tunnel operation trolleys are welded according to specific tunnel outline dimensions, they are less practical and are usually difficult to apply to tunnels of other outline dimensions, increasing the construction costs of the construction party.

[0003] In this regard, there are improved tunnel operation trolleys on the market. The improved tunnel operation trolleys are still based on an integrated frame, but they are equipped with telescopic platforms, lifting platforms and other devices on the integrated frame, so that the improved tunnel operation trolleys can meet the needs of tunnels within a certain range of outline dimensions, thus improving the applicability of the improved tunnel operation trolleys and expanding their scope of application. However, the improved tunnel operation trolleys still have the following shortcomings:

[0004] First, when the existing tunnel operation trolley is moved, it is mostly considered that the tunnel operation trolley moves along the length direction of the tunnel to meet the construction and renovation in the length direction of the tunnel; for the construction and renovation in the width direction of the tunnel, the tunnel operation trolley relies on the extension or retraction of the telescopic platform to adapt to the width of the tunnel, thereby solving the construction and renovation problems in the width direction of the tunnel; however, this method still limits the scope of application of the tunnel operation trolley to a certain extent, and there is a problem that the tunnel operation trolley is difficult to move horizontally in the width direction of the tunnel, or even cannot move horizontally;

[0005] Second, although a driving channel is set on the integrated frame of the tunnel operation trolley for construction vehicles to pass through, the integrated frame of the tunnel operation trolley will more or less compress the driving space because of the integrated structure of the frame. Therefore, the size of the construction vehicle is also limited (not too wide or too high), which affects the construction efficiency and increases the construction cost. Summary of the invention

[0006] In order to solve the above problems, the main purpose of the utility model is to provide a tunnel operation trolley which has high flexibility of use, strong practicality and can improve construction efficiency.

[0007] In order to achieve the main purpose of the utility model, the utility model provides a tunnel operation trolley, which includes a main frame, two flip platforms and a translation trolley, a lifting support mechanism is provided at the bottom of the main frame, the two flip platforms are distributed on both sides of the main frame along the moving direction of the tunnel operation trolley, the flip platform includes a flip table body and a first driving mechanism, the top of the flip table body is hinged with the main frame, the rotation axis of the flip table body is perpendicular to the moving direction, the bottom of the flip table body is provided with a roller and a locking member, the axis of the roller is parallel to the moving direction, the flip table body has an unfolding position and a recovery position, the first driving mechanism is connected between the main frame and the flip table body, the first driving mechanism can drive the flip table body to rotate between the unfolding position and the recovery position, the translation trolley includes a car body and two lifting driving mechanisms, the two lifting driving mechanisms correspond to the two flip platforms one by one, the lifting driving mechanism is installed on the car body, the lifting driving mechanism includes a transverse track, the transverse track is perpendicular to the moving direction, when the flip table body is in the recovery position, the lifting driving mechanism can drive the flip table body to lift, so that the transverse track contacts the roller, and the locking member is separated from the locking connection with the translation trolley.

[0008] As can be seen from the above, when the tunnel operation trolley needs to be moved, the main support is controlled by the translation trolley to move to the designated working position; at the same time, the main support and the flip platform can adjust their positions in the tunnel width direction through the lifting and driving mechanism of the translation trolley, so that the tunnel operation trolley can be applied to tunnel construction of different working conditions and different profile sizes, thereby improving the practicality of the tunnel operation trolley. After the position adjustment of the main support and the flip platform is completed (including the position adjustment of the main support in the length and width directions of the tunnel), the main support is fixed on the ground by the lifting support mechanism, and the translation trolley can be separated from the main support and the flip platform and moved to other areas for parking. The split support structure enables the tunnel operation trolley to have a larger driving space, which is conducive to improving construction efficiency and reducing construction costs. In addition, the main part of the tunnel operation trolley (including the main support, the flip platform, etc.) can also be adjusted in the width direction of the tunnel, which has the advantages of high adjustment flexibility and convenient adjustment, and is conducive to expanding the scope of application of the tunnel operation trolley. Furthermore, when the flip platform is in the unfolded position, it can also expand the operable area of ​​the tunnel operation trolley in the length direction of the tunnel, effectively expanding the operating range of the tunnel operation trolley.

[0009] A preferred solution is that a socket matching the locking piece is provided on the vehicle body; when the flip platform is in the retracted position, the lifting drive mechanism can drive the flip platform to descend until the locking piece is inserted into the socket, or the locking piece is a first telescopic rod, and when the flip platform is in the retracted position, the movable rod body of the first telescopic rod can be inserted into the socket.

[0010] It can be seen from the above that the above design can improve the firmness of the relatively fixed connection between the locking part and the vehicle body, further prevent the main support and the flip platform from being separated from the translation trolley during the movement of the tunnel operation trolley, and also ensure the safety of the tunnel operation trolley during movement.

[0011] Another preferred solution is that the bottom of the turning platform has a guide groove, which is parallel to the transverse track. When the roller contacts the transverse track, at least a portion of the transverse track is located in the guide groove.

[0012] As can be seen from the above, the above design can prevent the main part of the tunnel operation trolley from derailing from the transverse track, thereby ensuring the reliability and safety of the transverse movement of the main part of the tunnel operation trolley.

[0013] A further solution is that when there is a guide groove at the bottom of the flipping platform, an auxiliary wheel is provided on the transverse track, and the auxiliary wheel is rotatably installed in the transverse track, and the axis of the auxiliary wheel is parallel to the height direction of the main bracket; when the roller contacts the transverse track, the auxiliary wheel is adjacent to the side groove wall of the guide groove.

[0014] As can be seen from the above, the provision of the auxiliary wheels enables the main part of the tunnel operation trolley to move more smoothly relative to the transverse track, thereby making the position of the main part of the tunnel operation trolley in the width direction of the tunnel more convenient and labor-saving.

[0015] A further solution is that a connecting plate is provided between the two lifting drive mechanisms, and a guide column is provided at the bottom of the connecting plate; a guide sleeve matching the guide column is provided on the vehicle body, and the guide column is inserted into the guide sleeve.

[0016] As can be seen from the above, the above design enables the lifting drive mechanism to drive the main part of the tunnel operation trolley to lift and lower more smoothly and reliably, and can improve the strength and reliability of the lifting drive mechanism to ensure the safety of the translation trolley during use.

[0017] Another preferred solution is that the roller is an I-shaped wheel, and when the roller contacts the transverse track, the transverse track is engaged and connected with the I-shaped wheel.

[0018] As can be seen from the above, setting the roller as an I-shaped wheel can not only prevent the main part of the tunnel operation trolley from derailing from the transverse track, but also simplify the structure of the turning platform and the lifting drive mechanism.

[0019] Another preferred solution is that the first driving mechanism includes a tripod, a second telescopic rod and a third telescopic rod, the first corner of the tripod is hinged to the main frame, the second telescopic rod is hinged between the flip platform and the second corner of the tripod, and the third telescopic rod is hinged between the main frame and the third corner of the tripod.

[0020] As can be seen from the above, through the design of the first driving mechanism, the first driving mechanism can smoothly and reliably drive the flip platform to rotate relative to the main frame, and also enable the first driving mechanism to drive the flip platform to rotate over a large range, such as moving between the retracted position (the flip platform is in an upright state) and the deployed position (the flip platform is in a horizontal state).

[0021] A further solution is that the tunnel operation trolley also includes two first telescopic platforms and two second telescopic platforms. In the width direction of the main frame, the two first telescopic platforms are distributed on both sides of the main frame, the first telescopic platform includes a first translation platform body and a second driving mechanism, the first translation platform body is slidably connected to the main frame in the width direction, and the first driving mechanism can drive the first translation platform body to move, and in the width direction, the two second telescopic platforms are distributed on both sides of the main frame, the second telescopic platform is located above the first telescopic platform, the second telescopic platform includes a second translation platform body and a third driving mechanism, the second translation platform body is slidably connected to the main frame in the width direction, and the third driving mechanism can drive the second translation platform body to move.

[0022] As can be seen from the above, the first telescopic platform and the second telescopic platform can expand the operable area of ​​the tunnel work trolley in the tunnel width direction, thereby further expanding the operating range of the tunnel work trolley; in addition, the relative position setting of the first telescopic platform and the second telescopic platform enables construction personnel to work at different heights in the height direction of the main support.

[0023] A further solution is that the tunnel operation trolley also includes a lifting platform, which is located on the top of the main support. The lifting platform includes: a lifting platform body and a fourth driving mechanism, the fourth driving mechanism is connected between the lifting platform body and the main support, and the fourth driving mechanism can drive the lifting platform body to move in the height direction of the main support.

[0024] As can be seen from the above, the setting of the lifting platform can expand the operable area of ​​the tunnel operation trolley in the height direction of the main support, thereby further expanding the operating range of the tunnel operation trolley, and at the same time it is more conducive to construction personnel to carry out construction work on the top of the tunnel.

[0025] A further solution is that the main frame is provided with stairs, and the stairs pass through the first telescopic platform, the second telescopic platform and the lifting platform.

[0026] As can be seen from the above, the provision of stairs enables construction workers to enter the turning platform, the first translation platform, the second translation platform and the lifting platform more safely and conveniently. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Tunnel operation trolley embodiment

[0034] Reference Figure 1 The tunnel operation trolley 100 includes a main frame 1, a turnover platform 2, a translation trolley 3, a first telescopic platform 4, a second telescopic platform 5, a lifting platform 6 and a control system. The turnover platform 2, the first telescopic platform 4, the second telescopic platform 5 and the lifting platform 6 are all mounted on the main frame 1 to form the main part of the tunnel operation trolley 100. The translation trolley 3 is detachably connected to the turnover platform 2, so that the translation trolley 3 and the main part of the tunnel operation trolley 100 are in a split design. The translation trolley 3 is used to adjust the position of the tunnel operation trolley 100 in the tunnel.

[0035] The main support 1 has a driving channel, and the driving channel is parallel to the moving direction X of the tunnel operation trolley 100. A plurality of lifting support mechanisms 11 are provided at the bottom of the main support 1, and the lifting support mechanisms 11 can be extended or retracted in the height direction Z of the main support 1. The lifting support mechanism 11 preferably adopts a fourth telescopic rod (such as an oil cylinder or an electric cylinder, etc.), and the lifting support mechanism 11 is connected to the control system so that the control system can control the lifting support mechanism 11 to extend or retract. The lifting support mechanism 11 is used to cooperate with the ground, so that when the main part of the tunnel operation trolley 100 completes the position adjustment, the main part of the tunnel operation trolley 100 is supported and fixed on the ground by controlling the lifting support mechanism 11 to extend.

[0036] Combination Figure 2There are two flip platforms 2, and the two flip platforms 2 are distributed on both sides of the main support 1 along the moving direction X of the tunnel operation trolley 100; the two flip platforms 2 are arranged in a mirror-symmetrical manner. The flip platform 2 includes a flip platform body 21 and a first drive mechanism 22. The top of the flip platform body 21 is hinged to the main support 1, so that the flip platform body 21 can rotate relative to the main support 1, and the rotation axis of the flip platform body 21 is perpendicular to the moving direction X. Among them, the flip platform body 21 has an unfolded position and a retracted position; when the flip platform body 21 is in the unfolded position, the flip platform body 21 is in a horizontal state (such as Figure 5 When the flip table 21 is in the recovery position, the flip table 21 is in an upright state (as shown); Figure 4 In addition, a roller 211 and a locking member 212 are provided at the bottom of the flip platform 21, and the axis of the roller 211 is in the moving direction X.

[0037] The first driving mechanism 22 is connected between the main frame 1 and the flip platform 21, and the first driving mechanism 22 is used to drive the flip platform 21 to rotate between the unfolded position and the retracted position. Preferably, in this embodiment, the first driving mechanism 22 includes a tripod 221, a second telescopic rod 222 and a third telescopic rod 223, wherein the first corner of the tripod 221 is hinged to the main frame 1; the first end of the second telescopic rod 222 is hinged to the flip platform 21, and the second end of the second telescopic rod 222 is hinged to the second corner of the tripod 221, wherein the second corner is preferably located on the upper side of the first corner; the first end of the third telescopic rod 223 is hinged to the main frame 1, and the second end of the third telescopic rod 223 is hinged to the third corner of the tripod 221, wherein the third corner is preferably located on the upper side of the first corner, and in the moving direction X, the first corner is located between the second corner and the third corner.

[0038] The hinge axis between the tripod 221 and the support body, the second telescopic rod 222, and the third telescopic rod 223 is parallel to the width direction Y of the main support 1, and the hinge axis between the second telescopic rod 222 and the support of the flip table 21, and the hinge axis between the third telescopic rod 223 and the main support 1 are also parallel to the width direction Y. Through the design of the first driving mechanism 22, the first driving mechanism 22 can drive the flip table 21 to rotate in a large range, such as moving between the recovery position (the flip table 21 is in an upright state) and the unfolding position (the flip table 21 is in a horizontal state), and ensure the stability and reliability of the first driving mechanism 22 when driving the flip table 21. Among them, the second telescopic rod 222 and the third telescopic rod 223 can be an oil cylinder or an electric cylinder, and the second telescopic rod 222 and the third telescopic rod 223 are connected to the control system to be coordinated and controlled by the control system.

[0039] Combination Figure 3The translation trolley 3 includes a vehicle body 31, a lifting drive mechanism 32 and a control unit. A walking mechanism 311 is provided at the bottom of the vehicle body 31 to facilitate the movement of the translation trolley 3 itself and to facilitate the translation trolley 3 to drive the main part of the tunnel operation trolley 100 to move. There are two lifting drive mechanisms 32, and the two lifting drive mechanisms 32 correspond to the two turning platforms 2 one by one.

[0040] The lifting drive mechanism 32 is installed on the vehicle body 31. The lifting drive mechanism 32 includes a driving unit 321 and a transverse track 322. The driving unit 321 can preferably be a hydraulic cylinder or an electric cylinder, and the driving unit 321 is connected to the control unit to be controlled by the control unit. The transverse track 322 is connected to the driving end of the driving unit 321, so that the driving unit 321 can drive the transverse track 322 to move in the height direction Z. The transverse track 322 extends along the width direction Y, that is, the transverse track 322 is perpendicular to the moving direction X.

[0041] The translation trolley 3 can be moved into the driving channel of the main support 1 (i.e., located at the bottom of the main support 1), and is connected with the flip table 21. For example, when the flip table 21 is located at the recovery position, the lifting drive mechanism 32 can drive the transverse track 322 to move toward the flip table 21, so that the transverse track 322 contacts the roller 211 on the flip table 21, and drives the flip table 21 to rise, and the flip table 21 drives the main support 1 to rise synchronously; at this time, the locking member 212 is disengaged from the locking connection with the translation trolley 3, so that the flip table 21 can drive the main support 1 to move along the transverse track 322, so as to realize the position adjustment of the main part of the tunnel operation trolley 100 in the width direction Y (i.e., the width direction Y of the tunnel).

[0042] Preferably, the vehicle body 31 is provided with a socket 312 that matches the locking member 212. When the flip platform 21 is in the recovery position, when the lifting drive mechanism 32 drives the lateral track 322 to drive the flip platform 21 to descend to the initial position, the locking member 212 can be inserted into the socket 312, thereby improving the firmness of the relatively fixed connection between the locking member 212 and the vehicle body 31, better preventing the main frame 1 and the flip platform 2 from being separated from the translational trolley 3 during the movement of the tunnel operation trolley 100, and also ensuring the safety of the tunnel operation trolley 100 during movement.

[0043] In this embodiment, the locking member 212 is a fixed latch member. However, as another optional solution, in other embodiments, the locking member 212 can also be a first telescopic rod (such as a cylinder or an electric cylinder, etc.), the first telescopic rod is connected to the control system to be controlled by the control system, when the flip table 21 is in the recovery position, the movable rod body of the first telescopic rod can be inserted into the insertion hole 312, and the locking member 212 is set as the first telescopic rod, which is conducive to reducing the driving stroke of the lifting drive mechanism 32, lowering the driving center of the lifting drive mechanism 32, and thus improving the stability and reliability of the lifting drive mechanism 32 driving the flip table 21, the main frame 1, etc. to lift and lower.

[0044] As another optional solution, an electromagnet unit may be provided on the vehicle body 31 and / or the locking member 212. For example, an electromagnet unit may be provided on the vehicle body 31, the electromagnet unit may be connected to the control unit, and a component that may be magnetically adsorbed may be provided on the locking member 212. When the translation trolley 3 drives the main part of the tunnel operation trolley 100 to move, the control unit controls the electromagnet unit to generate a magnetic force to adsorb and fix the locking member 212. For another example, an electromagnet unit may be provided on the locking member 212, the electromagnet unit may be connected to the control system, and a component that may be magnetically adsorbed may be provided on the vehicle body 31. When the translation trolley 3 drives the main part of the tunnel operation trolley 100 to move, the control unit controls the electromagnet unit to generate a magnetic force to adsorb and fix the locking member 212. When the main part of the tunnel operation trolley 100 moves, the control system controls the electromagnet unit to generate magnetic force to adsorb and fix the locking piece 212; for another example, a first electromagnet unit is arranged on the vehicle body 31, and the first electromagnet unit is connected to the control unit, and a second electromagnet unit is arranged on the locking piece 212, and the second electromagnet unit is connected to the control system. When the translation trolley 3 drives the main part of the tunnel operation trolley 100 to move, the control unit controls the first electromagnet unit and the control system controls the second electromagnet unit, so that a magnetic force of attraction is formed between the first electromagnet unit and the second electromagnet unit.

[0045] Furthermore, the bottom of the flip table 21 has a guide groove 213, and the guide groove 213 is parallel to the transverse track 322. When the lifting drive mechanism 32 drives the transverse track 322 to move to contact the roller 211 of the flip table 21, at least a portion of the transverse track 322 is located in the guide groove 213. The design of the guide groove 213 can prevent the main part of the tunnel operation trolley 100 from derailing from the transverse track 322, thereby ensuring the reliability and safety of the main part of the tunnel operation trolley 100 moving along the transverse track 322.

[0046] Furthermore, the traverse track 322 is provided with auxiliary wheels 3221, which are rotatably mounted in the traverse track 322, and the axis of the auxiliary wheels 3221 is parallel to the height direction Z of the main support 1; when the roller 211 contacts the traverse track 322, the auxiliary wheels 3221 abut against the side groove wall of the guide groove 213. The provision of the auxiliary wheels 3221 enables the main part of the tunnel operation trolley 100 to move more smoothly relative to the traverse track 322, thereby making the position of the main part of the tunnel operation trolley 100 in the width direction Y of the tunnel more convenient and labor-saving.

[0047] It should be noted that, in other embodiments, the design of the guide groove 213 and the auxiliary wheel 3221 can be eliminated, and an I-shaped wheel can be used as the roller 211, so that when the I-shaped wheel contacts the transverse track 322, the transverse track 322 is engaged and connected with the I-shaped wheel. Using the roller 211 as an I-shaped wheel can prevent the main part of the tunnel operation trolley 100 from derailing from the transverse track 322, and can simplify the structure of the flip platform 21 and the lifting drive mechanism 32.

[0048] In addition, in order to enable the lifting drive mechanism 32 to drive the main part of the tunnel operation trolley 100 to lift and lower more smoothly and reliably, and to improve the strength and reliability of the lifting drive mechanism 32, and to ensure the safety of the translation trolley 3 during use, a connecting plate 33 is arranged between the two lifting drive mechanisms 32, and a guide column 331 is arranged at the bottom of the connecting plate 33. Matchingly, a guide sleeve 313 matching the guide column 331 is arranged on the vehicle body 31, and the guide column 331 is inserted into the guide sleeve 313.

[0049] Combination Figure 4 and Figure 5 The number of the first telescopic platforms 4 is preferably two, and in terms of width, the two first telescopic platforms 4 are distributed on both sides of the main frame 1. The first telescopic platform 4 includes a first translation platform body 41 and a second driving mechanism 42. The first translation platform body 41 is slidably connected to the main frame 1 in the width direction Y, and the second driving mechanism 42 is used to drive the first translation platform body 41 to move in the width direction Y to achieve the extension or retraction of the first translation platform body 41. Among them, the second driving mechanism 42 is preferably a cylinder or an electric cylinder, and the second driving mechanism 42 is connected to the control system to be cooperatively controlled by the control system.

[0050] There are two second telescopic platforms 5. In the width direction Y, the two second telescopic platforms 5 are distributed on both sides of the main frame 1, and the second telescopic platform 5 is located above the first telescopic platform 4. The second telescopic platform 5 includes a second translation platform body 51 and a third driving mechanism 52. The second translation platform body 51 is slidably connected to the main hanger in the width direction Y. The third driving mechanism 52 is used to drive the second translation platform body 51 to move in the width direction Y to achieve the extension or retraction of the second translation platform body 51. The third driving mechanism 52 is preferably an oil cylinder or an electric cylinder. The third driving mechanism 52 is connected to the control system to be controlled by the control system.

[0051] The first telescopic platform 4 and the second telescopic platform 5 can expand the operable area of ​​the tunnel operation trolley 100 in the tunnel width direction Y, thereby further expanding the operating range of the tunnel operation trolley 100. In addition, the relative position setting of the first telescopic platform 4 and the second telescopic platform 5 enables construction personnel to operate at different heights in the height direction Z of the main support 1.

[0052] The lifting platform 6 is located at the top of the main support 1. The lifting platform 6 includes a lifting platform body 61 and a fourth driving mechanism 62. The fourth driving mechanism 62 is connected between the lifting platform body 61 and the main support 1. The fourth driving mechanism 62 is used to drive the lifting platform body 61 to move in the height direction Z to achieve the extension or retraction of the lifting platform body 61. Among them, the fourth driving mechanism 62 can preferably be an oil cylinder or an electric cylinder. The fourth driving mechanism 62 is connected to the control system to be controlled by the control system. The setting of the lifting platform 6 can expand the operable area of ​​the tunnel operation trolley 100 in the height direction Z of the main support 1, thereby further expanding the operating range of the tunnel operation trolley 100, and at the same time, it is more conducive to the construction personnel to carry out construction work on the top of the tunnel.

[0053] In addition, the main frame 1 is provided with a staircase 12, which passes through the first telescopic platform 4, the second telescopic platform 5 and the lifting platform 6. The setting of the building allows construction workers to enter the turning platform 21, the first translation platform 41, the second translation platform 51 and the lifting platform 61 more safely and conveniently.

[0054] In summary, it can be seen that through the design of the tunnel operation trolley 100, when the tunnel operation trolley 100 needs to be moved, the main support 1 is controlled by the translation trolley 3 to move to the designated working position; at the same time, the main support 1 and the flip platform 2 can adjust their positions in the tunnel width direction Y through the lifting drive mechanism 32 of the translation trolley 3, so that the tunnel operation trolley 100 can be applied to tunnel construction with different working conditions and different profile sizes, thereby improving the practicality of the tunnel operation trolley 100. After completing the position adjustment of the main support 1 and the flip platform 2 (including the position adjustment of the main support 1 in the tunnel length direction and width direction Y), the main support 1 is supported and fixed on the ground by the lifting support mechanism 11, and the translation trolley 3 can be separated from the main support 1 and the flip platform 2 and moved to other areas for parking. The split support structure allows the tunnel operation trolley 100 to have a larger driving space, which is conducive to improving construction efficiency and reducing construction costs. In addition, the main part of the tunnel operation trolley 100 (including the main frame 1, the turning platform 2, etc.) can also be adjusted in the width direction Y of the tunnel, which has the advantages of high adjustment flexibility and convenient adjustment, which is conducive to expanding the application scope of the tunnel operation trolley 100. Furthermore, when the turning platform 21 is in the unfolded position, it can also expand the operable area of ​​the tunnel operation trolley 100 in the length direction of the tunnel, effectively expanding the operating range of the tunnel operation trolley 100.

[0055] Working method embodiment of tunnel operation trolley

[0056] The working method of this embodiment is applied to the tunnel operation trolley 100 described in the above tunnel operation trolley embodiment, and is specifically as follows:

[0057] In the initial state of the tunnel operation trolley 100 , the turning platform 21 is in the retracted position, the first translation platform 41 , the second translation platform 51 and the lifting platform 61 are in the retracted state, and the lifting support mechanism 11 is in the retracted state.

[0058] When the tunnel operation trolley 100 needs to be moved to the working position, the tunnel operation trolley 100 is controlled to move to the working position as a whole by the translation trolley 3 .

[0059] Next, the lifting drive mechanism 32 of the translation trolley 3 controls the transverse track 322 to rise, so that the transverse track 322 contacts the roller 211; then, the lifting drive mechanism 32 continues to control the transverse track 322 to rise until the locking piece 212 is disconnected from the body 31 of the translation trolley 3 (for example, in this embodiment, the locking piece 212 is disconnected from the socket 312).

[0060] Then, the main part of the tunnel operation trolley 100 (including the main body support 1, the turning platform 2, the first telescopic platform 4, the second telescopic platform 5, the lifting platform 6, etc.) can be moved along the transverse track 322 to adjust the position of the main part of the tunnel operation trolley 100 in the tunnel width direction Y.

[0061] After the position adjustment of the main part of the tunnel operation trolley 100 in the tunnel width direction Y is completed, the lifting support mechanism 11 at the bottom of the main frame 1 is controlled to extend so that the lifting support mechanism 11 is supported on the bottom surface, thereby achieving support and fixation of the main part of the tunnel operation trolley 100.

[0062] Next, the lifting drive mechanism 32 of the translation trolley 3 controls the transverse track 322 to descend to the initial position, so that the transverse track 322 is completely separated from the flip platform 21; then, the translation trolley 3 can be moved out from under the main support 1 to a designated position for parking.

[0063] Next, the first driving mechanism 22 of the turnover platform 2 drives the turnover platform body 21 to rotate to the unfolded position, so that the construction vehicle can pass through the driving passage of the main support 1. In addition, the second driving mechanism 42 of the first telescopic platform 4 can drive the first translation platform body 41 to extend, the third driving mechanism 52 of the second telescopic platform 5 can drive the second translation platform body 51 to extend, and the fourth driving mechanism 62 of the lifting platform 6 can drive the lifting platform body 61 to extend.

[0064] When it is necessary to move the main part of the tunnel operation trolley 100 to the next working position, the first driving mechanism 22 of the flipping platform 2 drives the flipping platform body 21 to rotate to the recovery position, the second driving mechanism 42 of the first telescopic platform 4 can drive the first translation platform body 41 to be recovered, the third driving mechanism 52 of the second telescopic platform 5 can drive the second translation platform body 51 to be recovered, and the fourth driving mechanism 62 of the lifting platform 6 can drive the lifting platform body 61 to be recovered.

[0065] Next, the translation trolley 3 is controlled to move to the bottom of the main frame 1 , so that the lifting drive mechanism 32 is aligned with the turning platform 21 .

[0066] Next, the lifting drive mechanism 32 of the translation trolley 3 controls the lateral track 322 to rise, so that the lateral track 322 contacts the roller 211; then, the lifting support mechanism 11 at the bottom of the main frame 1 contracts, breaks away from the contact with the ground, and contacts the support and fixation of the main frame 1.

[0067] Next, the lifting drive mechanism 32 of the translation trolley 3 controls the lateral track 322 to descend, so that the lateral track 322 drives the main part of the tunnel operation trolley 100 to descend until the locking rod is connected to the vehicle body 31 (such as the locking rod is inserted into the socket 312 in this embodiment) and the lateral track 322 is out of contact with the roller 211.

[0068] Then, the main part of the tunnel operation trolley 100 is controlled by the translation trolley 3 to move to the next working position and then the above-mentioned operation is repeated.

[0069] In summary, it can be seen that the working method of the tunnel working trolley provided by the utility model makes it more convenient to adjust the position of the tunnel working trolley 100 in the tunnel, and is beneficial to improving construction efficiency and reducing construction costs.

[0070] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
