Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of tunnel construction equipment, and particularly to a boom mobile arch installation vehicle. Background Art
[0002] Currently, boom-type tunnel arch installation vehicles can be divided into two categories:
[0003] The first category is as shown in Figure 1 In this type of boom-type tunnel arch installation vehicle, boom A4 and boom B5 are simultaneously hinged to a boom support 2 through two boom swing seats 3. The boom support 2 is fixed to the chassis frame 1. Through the left and right swing, up and down pitching of boom A4 and boom B5 relative to the boom support 2, and the telescopic movement of each boom, the working platform and the working device 6 connected to the end of the boom are moved to the specified spatial position, so that the working device 6 or the staff on the working platform can perform construction operations.
[0004] Due to structural limitations, this type of boom generally cannot achieve a swing of more than 180 degrees. As a result, the overall vehicle contraction state is too long, which is not conducive to transportation, or the effective coverage area within the operation radius is small, and it cannot meet the operation conditions of multiple steps and long distances, affecting the operation efficiency and other problems.
[0005] The first category is as shown in Figure 2 In this type of boom-type tunnel arch installation vehicle, boom A4 and boom B5 are simultaneously hinged to a boom support 2 through two boom swing seats 3. The boom support 2 is installed on the track of the chassis frame 1, and the boom support 2 can perform a sliding movement relative to the chassis frame 1. Through the sliding movement of the boom support 2, the left and right swing, up and down pitching of boom A4 and boom B5 relative to the boom support 2, and the telescopic movement of each boom, the working platform and the working device 6 connected to the end of the boom are moved to the specified spatial position, so that the working device 6 or the staff on the working platform can perform construction operations.
[0006] When the boom structure is in the transportation state, the boom support 2 slides to one end of the track. After the booms A4 and B5 are retracted and placed, the overall length of the vehicle is greatly shortened, solving the transportation problem. During the operation process, combined with the sliding movement of the boom support 2, the coverage area of the operation platform is increased, effectively improving the operation efficiency. However, since the booms A4 and B5 are connected to the same boom support 2, they move simultaneously during sliding, unable to meet the movement requirements of the independent movement of boom A4 or boom B5. On the other hand, the boom swing seat 3, the booms A4 and B5, the working platform and the working device 6, as well as the corresponding other accessories, and even the mass of the motor and the reducer are all attached to one boom support 2. The load of the sliding movement is large, requiring high requirements for the structure, kinematic pair, reducer, and drive structure of the boom support 2, with high manufacturing difficulty, high cost, and large load of the sliding movement, slow response speed, excessive ineffective load, and uneconomical. Summary of the Invention
[0007] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a boom-mobile arch installation vehicle with high flexibility, wide application range, easy operation, low failure rate, good response speed, and low manufacturing and assembly difficulty and cost.
[0008] To solve the above technical problems, the present invention adopts the following technical solutions:
[0009] A boom-mobile arch installation vehicle includes a chassis and more than one telescopic boom installed on the chassis. A working platform and a working device are installed on each telescopic boom. Each telescopic boom is installed on an independent moving platform through a swinging and pitching adjustment device. The moving platform is installed on the chassis in a manner that can move on the chassis. The boom-mobile arch installation vehicle further includes a moving drive assembly for driving the movement of the moving platform.
[0010] As a further improvement of the above technical solution:
[0011] The moving platform is installed on the chassis in a sliding manner through a sliding assembly.
[0012] The sliding assembly includes two first guide rails arranged at intervals. Each first guide rail has a guiding portion protruding towards the other first guide rail. The moving platform is provided with a moving support member supported on the upper surface of the guiding portion corresponding to each first guide rail, a bottom slider that abuts against the lower surface of the guiding portion and cooperates with the moving support member to prevent the moving platform from moving up and down, and a side slider that abuts against the side surface of the guiding portion to prevent the moving platform from moving away from the other first guide rail.
[0013] Two first limit members for restricting the moving range of the moving platform are provided on the chassis on both sides of the moving platform.
[0014] The mobile platform is also provided with a first pressing screw for forcing the bottom slider to closely adhere to the guiding part and a second pressing screw for forcing the side slider to closely adhere to the guiding part.
[0015] Corresponding to each first pressing screw, the bottom slider is provided with a first contact and cooperation part. The bottom slider is provided with a first positioning hole having a first counterbore at one end. The first contact and cooperation part includes a first inserting column part inserted into the first positioning hole and a first head part located in the first counterbore. The first pressing screw presses the first head part to force the bottom slider to closely adhere to the guiding part; corresponding to each second pressing screw, the side slider is provided with a second contact and cooperation part. The side slider is provided with a second positioning hole having a second counterbore at one end. The second contact and cooperation part includes a second inserting column part inserted into the second positioning hole and a second head part located in the second counterbore. The second pressing screw presses the second head part to force the side slider to closely adhere to the guiding part.
[0016] The sliding component includes two second guide rails arranged at intervals. Each second guide rail is provided with a guiding and limiting groove with an opening facing the other second guide rail. The mobile platform is provided with rollers corresponding to each second guide rail, which are placed in the guiding and limiting groove of the second guide rail and move along the guiding and limiting groove. The chassis is provided with two second limiting parts respectively arranged on both sides of the mobile platform for limiting the moving range of the mobile platform.
[0017] The mobile driving component includes a first chain, a first driving sprocket installed on the mobile platform, and a first driving mechanism installed on the mobile platform for driving the first driving sprocket to rotate. The two ends of the first chain are respectively connected to the chassis and meshed with the first driving sprocket.
[0018] The mobile driving component includes a second chain, a driven sprocket installed on the chassis, a driving sprocket installed on the chassis, and a second driving mechanism installed on the chassis for driving the driving sprocket to rotate. The two ends of the second chain respectively bypass the driven sprocket and the driving sprocket and are connected to the mobile platform.
[0019] The mobile driving component includes a rack installed on the chassis, a gear installed on the mobile platform, and a third driving mechanism installed on the mobile platform for driving the gear to rotate. The gear meshes with the rack.
[0020] Compared with the prior art, the advantages of the present invention are as follows:
[0021] The telescopic arms of the boom mobile arch installation vehicle of the present invention are respectively installed on independently moving mobile platforms. Each telescopic arm can move independently, which can meet the requirements of some special actions in arch installation, greatly improving the use flexibility and applicable range. At the same time, the load of a single mobile platform is small. Compared with multiple telescopic arms installed on a single mobile platform, it can be reduced by at least 50%, reducing the requirements for the structure of the mobile platform and the performance of the mobile drive components, and also reducing the manufacturing and assembly difficulty and cost. Moreover, a single mobile platform moves independently and will not drive other telescopic arms to move together, significantly reducing the dead load, effectively improving the operation performance and response speed, reducing the failure probability, and being more economical to use.

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0036] Embodiment 1:
[0037] As Figures 3 to 6 shown, the boom-mobile arch installation vehicle of this embodiment includes a chassis 1 and two telescopic arms 2 installed on the chassis 1. A working platform 3 and a working device 4 are installed on each telescopic arm 2. Each telescopic arm 2 is installed on an independent mobile platform 5 through a swing and pitch adjustment device 100. The mobile platform 5 is installed on the chassis 1 in a manner that can move on the chassis 1. The boom-mobile arch installation vehicle further includes a mobile drive assembly 6 for driving the mobile platform 5 to move. The telescopic arms 2 of the boom-mobile arch installation vehicle are respectively installed on independently moving mobile platforms 5. Each telescopic arm 2 can move independently, which can meet the requirements of some special actions in arch installation, greatly improving the use flexibility and application range; at the same time, the load of a single mobile platform 5 is small, which can be reduced by at least 50% compared with multiple telescopic arms 2 installed on a single mobile platform 5 at the same time, reducing the requirements for the structure of the mobile platform 5 and the performance of the mobile drive assembly 6, and also reducing the manufacturing and assembly difficulty and cost; and a single mobile platform 5 moves independently and will not drive other telescopic arms 2 to move together, significantly reducing the ineffective load, effectively improving the operation performance and response speed, reducing the failure probability, and being more economical to use. The boom-mobile arch installation vehicle can also control all telescopic arms 2 to move simultaneously by controlling each mobile platform 5 when needed.
[0038] The articulated boom gantry crane of this embodiment is provided with two telescopic booms 2. In other embodiments, only one telescopic boom 2 may be provided, or more than three telescopic booms 2 may be provided. The above-mentioned swing and pitch adjustment device 100, work platform 3 and working device 4 are all prior arts and can be configured with reference to existing gantry cranes.
[0039] In this embodiment, the mobile platform 5 is installed on the chassis 1 in a sliding manner through the sliding assembly 7, which has good movement stability, high reliability and is easy to implement.
[0040] In this embodiment, as Figures 4 to 6 shown, the sliding assembly 7 includes two first guide rails 71 arranged at intervals. Each first guide rail 71 has a guiding portion 7101 protruding towards the other first guide rail 71. The mobile platform 5 is provided with a moving support member 72 supported on the upper surface of the guiding portion 7101 corresponding to each first guide rail 71, a bottom slider 73 abutted against the lower surface of the guiding portion 7101 and cooperating with the moving support member 72 to prevent the mobile platform 5 from moving up and down, and a side slider 74 abutted against the side surface of the guiding portion 7101 to prevent the mobile platform 5 from moving away from the other first guide rail 71. Among them, the moving support member 72 serves to support the mobile platform 5 on the first guide rail 71 and slide along the first guide rail 71. The moving support member 72 can be a roller or a slider. Each first guide rail 71 cooperates with the moving support member 72 and the bottom slider 73 to limit the up and down movement freedom of the mobile platform 5. The two first guide rails 71 cooperate with their respective side sliders 74 to limit the horizontal movement freedom of the mobile platform 5. At the same time, the first guide rail 71, the moving support member 72, the bottom slider 73 and the side slider 74 jointly act to limit the rotational freedom of the mobile platform 5 in all directions, so that the mobile platform 5 can only slide along the first guide rail 71. The mobile platform 5 has good stability and high reliability, and the structure of this kind of sliding assembly 7 is simple, low in cost and easy to manufacture and assemble.
[0041] In this embodiment, two first limit members 75 are provided on the chassis 1 on both sides of the mobile platform 5 to limit the movement range of the mobile platform 5 and ensure that the telescopic boom 2 moves within a safe range.
[0042] In this embodiment, the mobile platform 5 is also provided with a first pressing screw 76 for forcing the bottom slider 73 to closely adhere to the guiding portion 7101 and a second pressing screw 77 for forcing the side slider 74 to closely adhere to the guiding portion 7101. The close adhesion degree of the bottom slider 73 and the side slider 74 to the guiding portion 7101 can be adjusted through the first pressing screw 76 and the second pressing screw 77, which is convenient for adjusting to ensure the stable reliability of the mobile platform 5 while smoothly sliding, and is also convenient for assembly and disassembly.
[0043] In this embodiment, a first contact fitting 78 is provided on the bottom slider 73 corresponding to each first pressing screw 76. The bottom slider 73 is provided with a first positioning hole having a first counterbore at one end. The first contact fitting 78 includes a first inserting post portion 781 inserted into the first positioning hole and a first head portion 782 located in the first counterbore. The first pressing screw 76 presses the first head portion 782 to force the bottom slider 73 to closely adhere to the guiding portion 7101. The first contact fitting 78 increases the contact area between the first pressing screw 76 and the bottom slider 73, ensuring that the surface of the bottom slider 73 is not damaged, prolonging the service life of the bottom slider 73, and also facilitating ensuring the effective pressing of the bottom slider 73. Preferably, the bottom slider 73 is made of a rubber part, and the first contact fitting 78 is made of a metal part; on the side slider 74, a second contact fitting 79 is provided corresponding to each second pressing screw 77. The side slider 74 is provided with a second positioning hole having a second counterbore at one end. The second contact fitting 79 includes a second inserting post portion 791 inserted into the second positioning hole and a second head portion 792 located in the second counterbore. The second pressing screw 77 presses the second head portion 792 to force the side slider 74 to closely adhere to the guiding portion 7101. The second contact fitting 79 increases the contact area between the second pressing screw 77 and the side slider 74, ensuring that the surface of the side slider 74 is not damaged, prolonging the service life of the side slider 74, and also facilitating ensuring the effective pressing of the side slider 74. Preferably, the side slider 74 is made of a rubber part, and the second contact fitting 79 is made of a metal part.
[0044] In this embodiment, as Figure 9 shown, the moving drive assembly 6 includes a first chain 61, a first drive sprocket 62 installed on the moving platform 5, and a first drive mechanism 63 installed on the moving platform 5 for driving the first drive sprocket 62 to rotate. Both ends of the first chain 61 are respectively connected to the chassis 1 and meshed with the first drive sprocket 62. When the first drive mechanism 63 drives the first drive sprocket 62 to rotate, the first drive sprocket 62 moves along the first chain 61, thereby driving the moving platform 5 to slide. The first drive sprocket 62 and the first drive mechanism 63 of this moving drive assembly 6 are both arranged on the moving platform 5, and the forward and reverse operations are smooth and stable, with low assembly requirements and simple installation and maintenance.
[0045] The above-mentioned first drive mechanism 63 adopts a combination of a motor and a speed reducer. In other embodiments, any existing drive mechanism that can realize driving the first drive sprocket 62 to rotate can also be used.
[0046] In this embodiment, two tensioning sprockets 64 are further installed on the moving platform 5. The two tensioning sprockets 64 are respectively arranged on both sides of the first drive sprocket 62 and force the first chain 61 to remain meshed with the first drive sprocket 62, which can prevent the first chain 61 from disengaging from the first drive sprocket 62 and make the meshing degree between the first chain 61 and the first drive sprocket 62 higher, improving the stability and reliability of the work.
[0047] In this embodiment, at least one end of the first chain 61 is connected to the moving platform 5 through a first tensioning and adjusting mechanism. The first tensioning and adjusting mechanism includes a first tensioning bolt 65 threadedly connected to the moving platform 5. The first chain 61 is connected to the first tensioning bolt 65. By screwing the first tensioning bolt 65, the relative position of the first tensioning bolt 65 on the moving platform 5 can be adjusted, and further the distance between the connection end and the other end of the first chain 61 connected to the first tensioning bolt 65 can be adjusted, so as to achieve the purpose of tensioning and loosening the first chain 61. By adjusting the tightness of the first chain 61, the stable cooperation between the first chain 61 and the first driving sprocket 62 can be ensured, the stability and reliability of the work can be improved, and at the same time, the assembly and disassembly are also convenient.
[0048] Embodiment 2:
[0049] The articulated boom gantry erector of this embodiment is basically the same as that of Embodiment 1. The main difference is that, as Figure 7 and Figure 8 shown, in this embodiment, the sliding assembly 7 includes two second guide rails 710 arranged at intervals. Each second guide rail 710 is provided with a guiding and limiting groove 711 with an opening facing the other second guide rail 710. The moving platform 5 is correspondingly provided with rollers 712 placed in the guiding and limiting groove 711 of each second guide rail 710 and moving along the guiding and limiting groove 711. Through the cooperation of the guiding and limiting grooves 711 of the two second guide rails 710 and the rollers 712, the moving platform 5 can only slide along the second guide rail 710, which has good stability and reliability, and the structure is simpler, the cost is lower, and it is easier to manufacture and assemble.
[0050] At the same time, two second limit members 713 for restricting the moving range of the moving platform 5 are provided on the chassis 1 and are respectively arranged on both sides of the moving platform 5 to ensure that the telescopic boom 2 moves within a safe range.
[0051] Embodiment 3:
[0052] The articulated boom gantry erector of this embodiment is basically the same as that of Embodiment 1. The main difference is that, as Figure 10As shown in the figure, in this embodiment, the mobile drive assembly 6 includes a second chain 66, a driven sprocket 67 mounted on the chassis 1, a driving sprocket 68 mounted on the chassis 1, and a second drive mechanism 69 mounted on the chassis 1 for driving the driving sprocket 68 to rotate. The two ends of the second chain 66 respectively bypass the driven sprocket 67 and the driving sprocket 68 and are connected to the mobile platform 5. The second chain 66 and the mobile platform 5 are connected to form an annular structure. When the second drive mechanism 69 drives the driving sprocket 68 to rotate, the driving sprocket 68 drives the second chain 66 to run, and then drives the mobile platform 5 to slide. The driven sprocket 67, the driving sprocket 68 and the second drive mechanism 69 of this kind of mobile drive assembly 6 are all arranged on the chassis 1, which can reduce the ineffective load of the mobile platform 5, is also convenient for further simplifying the structure of the mobile platform 5, effectively improves the stability and reliability of work, and is also convenient for maintenance.
[0053] The above-mentioned second drive mechanism 69 adopts a combination of a motor and a reducer. In other embodiments, any existing drive mechanism that can drive the driving sprocket 68 to rotate can also be used.
[0054] In this embodiment, at least one end of the second chain 66 is connected to the mobile platform 5 through a second tensioning adjustment mechanism. The second tensioning adjustment mechanism includes a second tensioning bolt 610 threadedly connected to the mobile platform 5, and the second chain 66 is connected to the second tensioning bolt 610. By screwing the second tensioning bolt 610, the relative position of the second tensioning bolt 610 on the mobile platform 5 can be adjusted, and then the position of the connection end of the second chain 66 and the second tensioning bolt 610 can be adjusted, so as to achieve the purpose of tensioning and loosening the second chain 66. By adjusting the tightness of the second chain 66, the stability and reliability of work can be improved, and at the same time, it is also convenient for assembly and disassembly.
[0055] Preferably, a guide wheel for guiding the second chain 66 and a supporting wheel for supporting the second chain 66 are arranged on the chassis 1 to ensure the normal operation of the second chain 66 without being interfered by other components.
[0056] Embodiment 4:
[0057] The boom mobile arch support installation vehicle of this embodiment is basically the same as that of Embodiment 1. The main difference is that, as Figure 11 shown in the figure, in this embodiment, the mobile drive assembly 6 includes a rack 611 mounted on the chassis 1, a gear 612 mounted on the mobile platform 5, and a third drive mechanism 613 mounted on the mobile platform 5 for driving the gear 612 to rotate. The gear 612 meshes with the rack 611. When the third drive mechanism 613 drives the gear 612 to rotate, the gear 612 moves along the rack 611, and then drives the mobile platform 5 to slide. The mobile drive assembly 6 with the cooperation form of the rack 611 and the gear 612 has a simpler structure, lower cost, and is easier to assemble and maintain.
[0058] The above-mentioned second driving mechanism 69 adopts a combination of a motor and a speed reducer. In other embodiments, any driving mechanism that can realize the rotation of the driving gear 612 in the prior art can also be adopted.
[0059] The mobile driving assembly 6 and the sliding assembly 7 in the above Embodiments 1 to 4 can be arbitrarily interchanged and combined. The mobile driving assembly 6 and the sliding assembly 7 can also adopt other prior arts.
