Description

Technical Field

[0001] The present application relates to the technical field of installation tools, and in particular to an adjustment mechanism and a bridge installation tool. Background Art

[0002] The main drive mechanical structure of a tunnel boring machine is mostly circular, and main bearings of different specifications correspond to main drive structures of different diameters. The bridge arrangement on the main drive is mostly segmented and circumferential; a variable diameter bridge is usually composed of multiple bridge pieces installed together. Variable diameter bridges are used in wiring situations involving circular structures of various diameters and can be arranged on main drive structures of various diameters. Currently, when installing a variable diameter bridge on main drive structures of different diameters, most operations involve first removing the multiple bridge pieces from the original diameter main drive structure, and then hoisting and installing them separately onto the main drive structure after the diameter is reduced.

[0041] In the above scheme, the telescopic directions of the first telescopic driving member, the second telescopic driving member and the third telescopic driving member are respectively arranged along the first direction, the second direction and the third direction; the first telescopic driving member telescopically drives the rocker to swing, thereby realizing the position swing adjustment of the part to be adjusted in the first direction; the second telescopic driving member telescopes and drives the position adjustment of the part to be adjusted in the second direction; the third telescopic driving member telescopes and drives the position adjustment of the part to be adjusted in the third direction; in summary, the adjustment mechanism of the present application can realize the position adjustment of the part to be adjusted in three directions.

[0042] As a preferred embodiment, the first, second, and third directions are arranged along the X, Y, and Z directions of the three-dimensional coordinate axes, respectively. More preferably, the first telescopic drive member in the adjustment mechanism is arranged to extend and retract along a tangential direction of the circumference, the second telescopic drive member is arranged to extend and retract along a radial direction of the circumference, and the third telescopic drive member is arranged to extend and retract along an axial direction of the circumference.

[0043] In the above scheme, the first telescopic drive member drives the rocker to swing, thereby driving the second telescopic drive member and the third telescopic drive member to swing in the circumferential direction, which is beneficial to adjusting the position of the adjusting mechanism in the circumferential direction, thereby facilitating the connection of the part to be adjusted and realizing the swing adjustment of the part to be adjusted in the circumferential direction; the third telescopic drive member is telescopic, which is beneficial to adjusting the position of the adjusting mechanism in the axial direction, thereby facilitating the connection of the part to be adjusted and realizing the position adjustment of the part to be adjusted in the axial direction; the second telescopic drive member is telescopic, which is beneficial to adjusting the position of the adjusting mechanism in the radial direction, thereby realizing the position adjustment of the part to be adjusted in the radial direction, thereby achieving variable control of the diameter of the part to be adjusted in the circumferential direction.

[0046] See also Figure 1 The rocker 22 is provided with a strip groove 23 extending along the second direction, and the first hinge point or first pin joint of the first support 21 is mounted in the strip groove 23. The strip groove structure facilitates adjustment of the installation position of the first hinge point or first pin joint in the first support.

More preferably, the output end of the third telescopic drive member is provided with a connecting plate 42 for connecting to an external part to be adjusted. A fixing seat is provided on the connecting plate, and a third mounting slot is provided on the fixing seat, and the output end of the third telescopic drive member is installed in the third mounting slot. The connecting plate increases the connection contact surface with the part to be adjusted, and while the connection is stable, it increases the operating space for connection with the part to be adjusted. Specifically, the connecting plate of this embodiment is an ordinary panel structure, and a connecting hole is provided on the panel. The connecting hole is preferably a strip-shaped through hole, which is connected to the part to be adjusted by a bolt passing through the strip-shaped through hole.

[0049] See also Figure 2-Figure 5 As shown, the present application also provides a bridge installation tool, comprising: a mounting plate 200 and multiple adjustment mechanisms 100 described above; the multiple adjustment mechanisms are arranged along the same circumference on the mounting plate. The entire bridge is composed of multiple bridge sections 300; the number of adjustment mechanisms is the same as the number of bridge sections.

[0050] The first support in the adjustment mechanism is fixedly arranged on the mounting plate, and the multiple adjustment mechanisms respectively utilize their own connecting plates to correspondingly connect the multi-section bridge frames that need to be adjusted and installed.

[0051] The first telescopic driving member in the adjusting mechanism is arranged along the tangential direction of the circumference; the second telescopic driving member in the adjusting mechanism is arranged along the radial direction of the circumference; and the third telescopic driving member in the adjusting mechanism is arranged along the axial direction of the circumference.

[0052] In the above scheme, the first telescopic drive member of the adjustment mechanism drives the rocker to swing, thereby driving the second telescopic drive member and the third telescopic drive member to swing in the circumferential direction, which is beneficial to adjusting the position of the adjustment mechanism in the circumferential direction, thereby facilitating the connection of the bridge frame single piece and realizing the swing adjustment of the bridge frame single piece in the circumferential direction; the third telescopic drive member is telescopic, which is beneficial to adjusting the position of the adjustment mechanism in the axial direction, thereby facilitating the connection of the bridge frame single piece and realizing the position adjustment of the bridge frame single piece in the axial direction; the second telescopic drive member is telescopic, which is beneficial to adjusting the position of the adjustment mechanism in the radial direction, thereby realizing the position adjustment of the part to be adjusted in the radial direction, thereby achieving variable control of the diameter of the bridge frame single piece in the circumferential direction.

[0053] During the use of the tooling, each section of the bridge can be fixed on multiple adjustment mechanisms on the tooling, effectively reducing the frequency of use of lifting tools when disassembling and assembling the bridge; at the same time, the slide-type rocker and the first oil cylinder are used in conjunction to realize the circumferential angle change of the adjustment mechanism, so that each adjustment mechanism in the tooling can adapt to different bridge piece connections within a certain circumferential angle range; multiple adjustment mechanisms are correspondingly connected to each section of the variable diameter bridge; each section of the bridge can realize radial jacking and retraction at the same time, greatly improving the work efficiency of disassembling and assembling the bridge piece when it moves from the initial circumference to the variable diameter circumference.

[0054] As a preferred embodiment, the mounting plate is a circular plate with concentric circular holes formed therein, forming a ring-shaped plate structure, thereby saving material costs. Multiple adjustment mechanisms are arranged in the circumferential directions of the concentric circles. The telescopic directions of the first telescopic drive members of the multiple adjustment mechanisms are arranged along the tangential directions of the concentric circles. When the bridge mounting fixture of the present application is used, the mounting plate is mounted on an external support base 400. The external support base is provided with an arcuate mounting groove surface that matches the mounting plate of the disc structure. The mounting plate is mounted on the arcuate mounting groove surface of the support base.

[0055] It should be noted that the bridge installation tooling of the present application also includes an existing controller. The first cylinder, the second cylinder and the third cylinder in the present application are all connected to the controller. The controller has an existing hydraulic and electrical control system built in. The hydraulic and electrical control system contains an existing editable control program and control instructions for controlling the telescopic stroke of the cylinder. The driving telescopic stroke of the first cylinder, the second cylinder and the third cylinder is controlled by the existing control program and control instructions.

[0056] The application implementation plan of the bridge installation tooling of this application:

[0057] The controller controls the first, second, and third cylinders of each adjustment mechanism to move telescopically, respectively, so that the connecting plates of each adjustment mechanism are respectively close to each bridge member of the integral bridge. The controller further controls the first, second, and third cylinders to fine-tune the connecting through-holes of the connecting plates so that the connecting through-holes of the connecting plates are aligned with the fixing plate holes at the bottom of the bridge member. The connecting plates and the fixing plates of the bridge member are fixedly connected by bolts passing through the connecting through-holes and the fixing plate holes. The fixing bolts of the bridge member and the initial diameter main drive structure are then removed.

[0058] By calculating the radius difference before and after the diameter change, the required lifting or retraction distance of the bridge frame unit after the diameter change is obtained; the hydraulic and electrical systems control the second cylinder to extend or retract the corresponding stroke distance, so that each bridge frame unit moves radially as a whole to the terminal state circumference after the diameter change; the controller further controls the first cylinder, the second cylinder and the third cylinder to fine-tune the movement, so that each bridge frame unit and the bottom plate hole on the diameter-changing main drive structure are aligned, and the bridge frame unit and the bottom plate of the diameter-changing main drive structure are fixed with bolts; finally, the fixing bolts between the connecting plate and the bridge frame unit are removed to complete the diameter-changing installation of the entire bridge frame.

[0059] When the bridge installation tool of the present application is not in use, the second cylinder and the third cylinder are controlled to retract, and the first cylinder is controlled to extend, so that the rocker is swung to the maximum angle, which can effectively fold the various adjustment mechanisms on the tool and reduce the occupied space.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
