Detailed Description
The foregoing and other technical matters, features and effects of the present invention will be described in detail with reference to the accompanying drawings 1 to 15.
as shown in fig. 4, there is provided a structure of an adjusting device: the two-way screw rod 32 is installed in threaded fit with the two walking frames 1 respectively, a handle 33 is arranged in the middle of the two-way screw rod 32, a worker can adjust the distance between the two walking frames 1 by holding the handle 33 and screwing the two-way screw rod 32, and then the walking auxiliary units respectively abut against the flange plates 29 at the upper ends of the rigid web plates at two sides (the two walking frames 1 are positioned along the direction perpendicular to the rigid web plates);
when the device works, as shown in figure 1, before a rigid web plate to be installed is hoisted, a worker firstly adjusts the adjusting device and the telescopic swing arm 4 and completes the positioning of the two walking frames 1 between two rigid web plates which are installed, then the rigid web plate to be installed is hoisted to a position to be installed through the crane, namely the position of the single rigid web plate in figure 1 (the crane only hoists the rigid web plate to be installed to the position near the position to be installed), then the worker controls the adsorption device arranged on the walking sub-unit to work and adsorbs the walking frame 1 on the rigid web plate through the adsorption device (the adsorption device arranged on the walking sub-unit adsorbs the walking frame 1 on the flange plate 29 at the upper end of the rigid web plate and realizes the positioning of the walking frame 1), then the worker controls the driving device arranged on the walking frame 1 to act, so that the telescopic swing arm 4 rotates and rotates by 90 degrees, after the telescopic swing arm 4 rotates by 90 degrees (at this time, the walking frame 1 is not in contact with the upper top plate and the lower bottom plate of the bridge any more and is in a suspended state, and the walking frame 1 is positioned by the adsorption device arranged on the walking sub-unit), the telescopic swing arm 4 is driven to move towards the direction close to the rigid web plate under the action of the driving device, so that the walking main unit arranged on the telescopic swing arm 4 moves to the position in contact with the rigid web plate which is installed (at this time, the driving device stops acting), and the state of the device is as shown in fig. 8 at this time;
note: in the process that the driving device drives the telescopic swing arm 4 to move towards the position close to the rigid web, a worker should simultaneously control the telescopic swing arm 4 to stretch and contract and enable the walking main units arranged at the two ends of the walking main units to respectively correspond to the mounted rigid web and the protruding positions of the rigid web to be mounted (as shown in figure 9),
as shown in fig. 9, the worker then controls the telescopic swing arm 4 to extend and retract, and makes the walking main unit at one end correspond to the convex part of the rigid web to be installed, and makes the walking main unit at the other end correspond to the convex part of the rigid web to be installed (the crane hoists the rigid web to be installed to the position near the position to be installed in advance), and under the action of the driving device, the driving device stops working until the walking main unit moves to be in contact with the convex part of the rigid web, and at this time, the walking main unit installed on the telescopic swing arm 4 and in contact with the convex part of the rigid web to be installed, and the walking main unit at the other end also moves to be in corresponding to the convex part of the rigid web to be installed (the two may not be in contact, and when wind exists, the rigid web to be installed is in the air under the action of the crane, and may be in a swaying state and may swing), and then the worker controls the adsorption device on the walking main unit corresponding to the rigid web to be installed to work and makes the adsorption device to be installed to correspond to the rigid web to the convex part The walking frame 1 is more firmly adsorbed on the rigid web plate after the installation under the action of the suction force of the adsorption device, then the rigid web plate to be installed moves towards one end of the installed rigid web plate by controlling the crane, as shown in fig. 3, one end of the rigid web to be installed is slowly close to one side of the installed rigid web, so that the bolt holes on the two steel web plates are corresponding to each other, when the bolt holes on the two steel web plates are adjusted to the corresponding positions, the worker controls the adsorption device on the walking main unit corresponding to the rigid web plate to be installed to work and adsorb the rigid web plate to be installed, under the action of the telescopic swing arm 4 and the adsorption devices at the two ends of the telescopic swing arm, the rigid web to be installed and the installed rigid web are kept coplanar as shown in fig. 9 (the length extension direction of the telescopic swing arm 4 is kept parallel to the rigid web, and the rigid web in a hoisting state and the installed rigid web are kept coplanar through the adsorption devices);
when a worker adjusts the position of the rigid web plate to be installed through the crane (namely, in the process of aligning the bolt holes on the side walls of the two rigid web plates), if the worker encounters strong wind or airflow flow, the adsorption device corresponding to the rigid web plate to be installed can be controlled to work, the rigid web plate to be installed can be adsorbed to avoid large amplitude swing (which is not beneficial to subsequent alignment adjustment) caused by the strong wind, when the wind speed is reduced or no wind exists, the adsorption device corresponding to the rigid web plate to be installed is controlled to stop working, and the alignment process of the bolt holes of the rigid web plate is continuously started (after the adsorption device stops working, the adsorption force is not generated on the rigid web plate any more, the position of the rigid web plate to be installed can be continuously adjusted and moved through the crane, so that the position adjustment of the bolt holes on the side walls of the two rigid web plates is greatly facilitated) until the alignment of the bolt holes on the side walls of the two rigid web plates is completed, Adjusting;
then, workers can insert high-strength bolts into bolt holes in the two rigid webs and fasten the bolts to realize connection and fixation between the two rigid webs (finally, permanent fixed connection between two adjacent rigid webs is realized by welding), so that even if strong wind or airflow flows are generated in the fastening process of the workers through the high-strength bolts, the rigid webs in a hoisting state cannot swing, the efficient and stable connection and fixation of the workers to the two rigid webs are facilitated (if the rigid webs to be installed swing and swing to a large extent in the fastening process of the bolts, the installed bolts are easily broken due to the swing of the rigid webs, and serious hidden danger is caused to the life safety of the workers);
because the device symmetry sets up, promptly, control flexible swing arm 4 on two walking frame 1 and locate the walking main unit, adsorption equipment simultaneous working on the walking subelement, the workman can realize hoisting two rigid webs simultaneously and carry out accurate counterpoint to it, treat that the workman accomplishes the connection of rigid web through high strength bolt, fixed back, begin to tie up the reinforcing bar afterwards, concrete placement, treat that the concrete sets up after reaching certain intensity, then begin the installation of next group rigid web, the workman need reset the device this moment, promptly, by state recovery to as in the attached figure 1 in the figure 9, concrete process is as follows: the suction devices on the two walking main units are controlled to stop working, then the driving device drives the telescopic swing arms 4 to move towards the direction far away from the rigid web plate and adjust the telescopic swing arms to be in a vertical state from the horizontal state, then the telescopic swing arms 4 are controlled to stretch out and draw back, so that the walking main units installed at the two ends of the walking main units are abutted to the upper top plate and the lower bottom plate of the bridge again (as shown in the attached drawing 1, the suction devices on the walking auxiliary units can be controlled to stop working at the moment, the suction force is not required to be provided by the walking auxiliary units), and then workers control the walking main units to work to move under the limiting of the rigid web plate, the upper top plate and the lower bottom plate of the bridge (the whole process does not need to be operated by too much manual workers and does not need to disassemble any positioning device).
as shown in fig. 3, the mounting frames 8 at both sides of the power wheel 9 are provided with auxiliary wheels 10 (driven wheels), the auxiliary wheels 10 are used for increasing the contact area between the device and the upper top plate and the lower bottom plate of the bridge, so that the stress is more uniform and the device is more stable in the walking process, the adsorption device is arranged on the auxiliary wheels 10, as shown in fig. 8, the width of the auxiliary wheels 10 is larger than that of the driving wheel, the contact area between the auxiliary wheels 10 and the upper top plate and the lower bottom plate of the bridge is further increased, and when the auxiliary wheels 10 are abutted against the convex parts on the side walls of the rigid web plate, the power wheel 9 is still spaced from the side walls of the rigid web plate by a certain distance (as shown in fig. 8, the device is used for adsorbing the walking frame 1 on the rigid web plate by virtue of the adsorption device arranged on the auxiliary wheels 10);
when the device moves, the telescopic swing arm 4 is in a vertical state, as shown in fig. 2, at the moment, the power wheel 9 and the auxiliary wheel 10 are abutted to the upper top plate and the lower bottom plate of the bridge, when the device performs auxiliary positioning, the telescopic swing arm 4 is in a horizontal state, as shown in fig. 8, the telescopic swing arm 4 is switched from the vertical state to the horizontal state, only the rotary motor 7 is controlled to start and drive the screw rod 3 to rotate, when the rotary motor 7 drives the circular table 5 to rotate for 90 degrees through the screw rod 3 (from the initial vertical state to the horizontal state), then the circular table 5 is driven to move towards the direction close to the rigid web plate along with the continuous rotation of the rotary motor 7, so that the side walls of the auxiliary wheels 10 installed at the two ends of the installation frame 8 are abutted to the protruding parts of the rigid web plate (as shown in fig. 8).
as shown in fig. 5, after the worker connects and fixes two adjacent rigid webs through a high-strength bolt and performs permanent welding through welding, the worker controls the suction device arranged on the auxiliary wheel 10 to stop working, controls the rotating motor 7 to drive the circular truncated cone 5 to move towards the direction away from the rigid webs and adjust the telescopic swing arm 4 in the horizontal state to be in the vertical state, then controls the telescopic swing arm 4 to stretch and contract so that the power wheel 9 and the auxiliary wheel 10 arranged on the mounting frame 8 are abutted against the upper top plate and the lower bottom plate of the bridge, controls the suction device arranged on the auxiliary wheel 13 to stop working and controls the power wheel 9 to start to drive the device to move forward for a certain distance, namely, the device moves to the position shown in fig. 14 from the position shown in fig. 1 (namely, the auxiliary wheel 10 positioned below is moved to the edge position of the lower bottom plate of the bridge, and at this time the device cannot move forward continuously), then the worker can screw the screw 12 and make the sub-frame 11 contracted on the walking frame 1 extend outward, as shown in fig. 14, make the sub-wheel 13 installed on the sub-frame 11 move forward a certain distance along the side wall of the flange plate 29 at the upper end of the rigid web plate which has been connected and fixed (preferably make the sub-wheel 13 move to the middle position of the rigid web plate), at this time, the worker controls the suction device on the sub-wheel 13 to start the work again (at this time, the suction device on the movable sub-wheel 13 sucks the rigid web plate), at this time, another sub-wheel 13 on the sub-frame 11 fixedly installed on the walking frame 1 is abutted against the side wall of the flange plate 29 at the upper end of the rigid web plate which has been installed, under the cooperation of the two sub-frames 11 and the sub-wheel 13 installed on the sub-frame 11, further assistance and strengthening positioning of the rigid web plate after completing the bolt connection and welding can be realized, so as to avoid the following steel bar bundling, In the concrete pouring process, when strong wind or strong convection weather occurs, the rigid web plates shake due to the fact that the windward area of the rigid web plates is large (because only one side of each rigid web plate is connected with the rigid web plate which finishes concrete pouring, the other end of each rigid web plate is still in an unfixed state), and connecting and fixing parts between every two adjacent rigid web plates are damaged (bolts are distorted and deformed or cracks appear at welding parts);
at this time, the two traveling frames 1 are positioned between the top plate, the bottom plate and the two rigid webs of the bridge through the corresponding telescopic swing arms 4 (the power wheels 9 and the auxiliary wheels 10 arranged at the two ends of the telescopic swing arms 4 respectively abut against the top plate and the bottom plate of the bridge) and the auxiliary frames 11 fixedly arranged with the traveling frames 1 (abut against the side walls of the rigid web flange plates 29 for completing concrete pouring), and the auxiliary frames 11 (which are auxiliary supports and reinforcing points) which extend out of the traveling frames 1 and are in contact with the rigid webs to be poured with concrete are positioned between the top plate, the bottom plate and the two rigid webs of the bridge, and the cross frames (the matched telescopic swing arms 4, the traveling frames 1 and the fixedly arranged auxiliary frames 11) are used as bodies to realize reliable positioning in the vertical direction and in the direction perpendicular to the side walls of the rigid webs.
In the above process, the one-way worm 17 and the lead screw satisfy: the rotation of the lead screw will not drive the one-way worm 17 to rotate (i.e. the one-way worm 17 is in a static state in the above process), so the worm wheel 18 engaged therewith will not rotate, and the worm wheel 18 will not drive the transmission device connected therewith to drive the two position-limiting rods 15 to move, i.e. the two position-limiting rods 15 will not move in the above process (after the two position-limiting rods 15 are inserted into the position-limiting holes 16 under the action of the expansion springs 20).
Embodiment 6, on the basis of embodiment 5, as shown in fig. 6, the transmission device includes a sector gear 21 rotatably mounted on the walking frame 1, the sector gear 21 is matched with an intermediate gear 22 rotatably mounted on the cylinder 19, a gear system 23 meshed with the intermediate gear 22 is arranged on the outer wall of the limiting rod 15 (as shown in fig. 7, the gear system 23 is arranged inside the circumferential surface of the limiting rod 15 and does not interfere with the sliding of the limiting rod 15 in the limiting hole 16), and when the setting is started, the sector gear 21 and the intermediate gear 22 rotatably mounted on the cylinder 19 are not meshed together, as shown in fig. 6;
the worm wheel 18 drives the corresponding sector gear 21 through belt transmission, when the telescopic swing arm 4 rotates from an initial vertical state to a horizontal state, the lead screw cannot drive the one-way worm 17 to rotate and the sector gear 21 cannot rotate, so that when the telescopic swing arm 4 rotates to the horizontal state, the positions of the two limiting holes 16 just correspond to the positions of the two limiting rods 15, and the limiting rods 15 are inserted into the limiting holes 16 under the action of the telescopic spring 20 (in the process, the movement of the limiting rods 15 drives the intermediate gear 22 to idle through the matching of the gear system 23 and the intermediate gear 22);
when the telescopic swing arm 4 needs to be restored to the state shown in fig. 1 from the state shown in fig. 9, the rotating motor 7 is started and controlled to start reverse rotation, the round platform 5 in threaded fit with the rotating motor 7 is driven by the lead screw to move in the direction away from the rigid web plate along with the reverse rotation of the rotating motor 7, meanwhile, the one-way worm 17 rotating coaxially with the lead screw starts to be driven synchronously along with the reverse rotation of the lead screw, the one-way worm 17 rotates to drive the sector gear 21 to rotate synchronously through the worm gear 18 and the belt transmission, the sector gear 21 starts to be meshed with the intermediate gear 22 after rotating for a certain angle along with the rotation of the sector gear, and the limiting rod 15 is driven synchronously to move in the direction compressing the telescopic spring 20 through the meshing of the intermediate gear 22 and the tooth system 23 arranged on the limiting rod 15, namely, the round platform 5 moves in the direction away from the rigid web plate, the limiting rod 15 inserted into the limiting hole 16 synchronously moves towards the direction away from the rigid web plate under the action of the intermediate gear 22 (as long as the limiting rod 15 is not withdrawn from the limiting hole 16, the circular truncated cone 5 can be driven to continuously move towards the direction away from the rigid web plate along with the reverse rotation of the screw rod);
when the circular truncated cone 5 moves to the initial position, the sector gear 21 is just disengaged from the intermediate gear 22, and the intermediate gear 22 is just matched with the gear system 23 arranged on the limiting rod 15 to completely pull out the limiting rod 15 from the limiting hole 16, and at the moment, along with the continuous rotation of the rotating motor 7, the circular truncated cone 5 is driven by the lead screw to synchronously rotate (the circular truncated cone 5 loses circumferential positioning), so that after the circular truncated cone 5 is driven to rotate for 90 degrees, the rotating motor 7 stops working, and the telescopic swing arm 4 is restored to the vertical state (namely, the initial position state) from the horizontal state;
note: when the sector gear 21 is separated from the intermediate gear 22 and the rotating motor 7 continues to rotate to the stop process, the rotating motor 7 can drive the sector gear 21 to continue to rotate, and when the rotating motor 7 stops working again, the sector gear 21 is just driven to rotate for a whole circle (namely, the sector gear 21 is driven to rotate to the initial position), a worker can realize the switching of the device between the walking state (shown in the attached drawing 1) and the working state (shown in the attached drawing 9) only by controlling the work of the rotating motor 7 and the work of the adsorption device and enabling the two to work in cooperation, the operation process is simple and convenient, too much manual operation of the worker is not needed, the work load of the worker is greatly reduced, and meanwhile, the construction efficiency is also improved.
as shown in fig. 10, the sector 25, the outer arc surface of the power wheel 9 and the outer arc surface of the secondary wheel 13 are covered with a layer of rubber pad 26, so that the device has a certain degree of elasticity in the walking process (in the walking process of the upper top plate and the lower bottom plate of the bridge, the passing can be completed by extruding the rubber pad 26 when encountering uneven pouring surfaces, thereby avoiding damaging the telescopic rod 6), and the covered rubber pad 26 also plays a certain role in protecting the electromagnet 14 arranged in the sector 25.
In embodiment 8 and embodiment 7, as shown in fig. 11, a driving plate 27 (the driving plate 27 and the rotating shaft 24 are coaxially and alternately arranged) which is coaxially arranged with the rotating shaft 24 is rotatably mounted on the mounting frame 8, as shown in fig. 13, a driving rod 28 which is rotatably mounted with the driving plate 27 is arranged on the driving plate 27 in an alternate surrounding manner, and the other end of the driving rod 28 is rotatably mounted with the sector 25, so that when a worker drives the driving plate 27 to rotate through a transmission device, the driving rod 28 can drive the plurality of sectors 25 to synchronously expand towards a direction away from the center of the driving plate 27 or gather towards a direction close to the center of the driving plate 27.
before the telescopic swing arm 4 is switched from the vertical state to the horizontal state, that is, during the switching from the state shown in fig. 1 to the state shown in fig. 9, as shown in fig. 15, a worker can synchronously control the power wheel 9 to rotate reversely by a certain angle (the angle is satisfied: after the driving plate 27 rotates by the angle, the fan-shaped blocks 25 can be expanded outwards to the maximum extent) and along with the reverse rotation of the power wheel 9 (the power wheel 9 rotates along the counterclockwise direction), the one-way shaft 34 is synchronously driven to rotate along the counterclockwise direction, the toothed belt wheel in the toothed belt wheel set 31 is sleeved on the one-way shaft 34, the one-way shaft 34 drives the toothed belt wheel set 31 to rotate along the counterclockwise direction shown in fig. 15, and further drives the driving plate 27 to rotate relative to the rotating shaft 24 (preferably, a brake for locking the two rotating shafts 24 can be arranged on the mounting bracket 8, that is, the rotating shaft 24 is held tightly by the brake, so that when the driving plate 27 is driven by the cog belt wheel set 31 to rotate, the rotating shaft 24 is in a braked state, that is, the rotating shaft 24 cannot rotate, the brake is the prior art, such as a disc brake, a drum brake, etc., and is mostly applied to the field of automobile wheel braking, since the structure of the prior art is not described in detail herein, those skilled in the art can obtain the invention based on the prior art and in combination with the present solution), the rotation of the driving plate 27 is accompanied by the rotation of the driving rods 28 to drive the plurality of segments 25, which are slidably mounted along the radial direction of the rotating shaft 24, to expand outward and switch from the state shown in fig. 5 to the state shown in fig. 11, at which time the torsion spring disposed between the rotating shaft 24 and the driving plate 27 is in a compressed energy storage state (the motor for driving the power wheel 9 to operate is a motor with a band-type brake self-locking function);
when the sector blocks 25 need to be reset (the process should be carried out and completed before the telescopic swing arm 4 is not restored to the vertical state), the worker only needs to control the power wheel 9 to rotate reversely, i.e. in a clockwise direction as shown in fig. 15, in which the brake should maintain the braking condition of the shaft 24, with a clockwise rotation of the power wheel 9, the drive plate 27 will rotate in a clockwise direction as viewed in figure 15 under the influence of the torsion spring, so that the driver plate 27 is reversed by a corresponding angle to bring the segments 25 together again, i.e., as in the state of fig. 5 (in which the diameter of the auxiliary wheel 10 is kept the same as that of the power wheel 9), and then the worker controls the brake to release the brake of the rotating shaft 24, during the subsequent clockwise rotation of the power wheel 9 as shown in fig. 15, the rotation shaft 24 is moving forward.
The above description is only for the purpose of illustrating the present invention, and it should be understood that the present invention is not limited to the above embodiments, and various modifications conforming to the spirit of the present invention are within the scope of the present invention.
