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 flange plates 29 at the upper ends of the steel web plates 2 at two sides (positioning of the two walking frames 1 in the direction perpendicular to the steel web plates 2 is achieved);
when the device works, as shown in figure 1, before hoisting a steel web 2 to be installed, a worker firstly adjusts the adjusting device and the telescopic swing arm 4 and finishes the positioning of two walking frames 1 between two completely installed steel webs 2, then the steel web 2 to be installed is hoisted to a position to be installed by a crane, namely the position of the single steel web 2 in figure 1 (the crane only hoists the steel web 2 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 to the steel web 2 by the adsorption device (the adsorption device arranged on the walking sub-unit adsorbs the walking frame 1 to a flange plate 29 at the upper end of the steel web 2 and realizes the positioning of the walking frame 1), subsequently, the worker controls the driving device arranged on the walking frame 1 to act, so that the telescopic swing arm 4 rotates and makes the telescopic swing arm rotate 90 degrees, and after the telescopic swing arm 4 rotates 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 positioning of the walking frame 1 is realized through the adsorption device arranged on the walking sub-unit), the telescopic swing arm 4 is driven to move towards the direction close to the steel web 2 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 steel web 2 which is installed (at this time, the driving device stops acting), and at this time, the state of the device is as shown in fig. 8;
note: in the process that the driving device drives the telescopic swing arm 4 to move towards the steel web 2, a worker should control the telescopic swing arm 4 to stretch and contract at the same time and enable the walking main units arranged at the two ends of the walking main units to respectively correspond to the steel web 2 which is installed and the convex positions of the steel web 2 to be installed (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 raised part of the steel web 2 to be installed, and makes the walking main unit at the other end correspond to the raised part of the steel web 2 to be installed (the crane hoists the steel web 2 to be installed to the position near the position to be installed in advance), and when the walking main unit moves to the position corresponding to the raised part of the steel web 2 under the action of the driving device, the driving device stops working, and at this time, the walking main unit is installed on the telescopic swing arm 4 and butts against the raised part of the steel web 2 to be installed, and the walking main unit at the other end also moves to the position corresponding to the raised part of the steel web 2 to be installed (the two may not be in contact yet, and when wind exists, the steel web 2 to be installed is in the air under the action of the crane, and is in a swaying state and swings), then, a worker controls the suction devices on the walking main unit corresponding to the finished installation of the steel web 2 to work and enables the walking frame 1 to be more stably sucked on the finished installation of the steel web 2 under the suction effect of the suction devices, then the steel web 2 to be installed moves towards one end of the installed steel web 2 by controlling a crane, as shown in figure 3, one end of the steel web 2 to be installed is slowly close to one side of the installed steel web 2, so that bolt holes on the two steel webs 2 correspond to each other, when the bolt holes on the two steel webs 2 are adjusted to the corresponding positions, the worker controls the suction devices on the walking main unit corresponding to the steel web 2 to be installed to work and suck the steel web 2 to be installed, and the steel web 2 to be installed and the installed steel web 2 are kept coplanar under the effect of the telescopic swing arms 4 and the suction devices at the two ends of the telescopic swing arms, as shown in the attached figure 9 (the length extending direction of the telescopic swing arm 4 is kept parallel to the steel web 2, and the steel web 2 in a hoisting state and the installed steel web 2 are kept coplanar through an adsorption device);
when a worker adjusts the position of the steel web 2 to be installed through a crane (namely, in the process of aligning the bolt holes on the side walls of the two steel webs 2), if strong wind or airflow flows, the worker can control the adsorption device corresponding to the steel web 2 to be installed to work and realize the adsorption of the steel web 2 to be installed so as to avoid the large-amplitude swing (which is not beneficial to the subsequent alignment adjustment) caused by the strong wind, and when the wind speed is reduced or no wind exists, the worker can control the adsorption device corresponding to the steel web 2 to be installed to stop working and continue to start the alignment process of the bolt holes of the steel web 2 (after the adsorption device stops working, the adsorption force is not generated on the steel web 2, the crane can continue to adjust and move the position of the steel web 2 to be installed, so that the position adjustment of the steel web 2 is greatly facilitated), until the alignment and the adjustment of the bolt holes on the side walls of the two steel webs 2 are completed;
then, a worker can insert and fasten the high-strength bolts into the bolt holes in the two steel web plates 2 to realize connection and fixation between the two steel web plates 2 (finally, the permanent fixed connection between the two adjacent steel web plates 2 is realized by welding), so that even if the worker fastens the high-strength bolts, the worker can generate strong wind or airflow to flow in the process of fastening the high-strength bolts, the steel web plates 2 in a hoisting state can not swing, the efficient and stable connection and fixation of the worker to the two steel web plates 2 are facilitated (if the steel web plates 2 to be installed swing and shake greatly in the process of fastening the bolts, the installed bolts are easily broken due to the swing of the steel web plates 2, and the potential safety hazard to the worker is seriously caused);
because the device symmetry sets up, namely, 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 steel web 2 simultaneously and carry out accurate counterpoint to it, treat that the workman passes through the connection that high strength bolt accomplished steel web 2, fixed back, begin to tie up the reinforcing bar afterwards, concrete placement, treat that the concrete setting reaches behind the certain strength, then begin the installation of next group of steel web 2, the workman need reset the device this moment, promptly, by state recovery in figure 9 to state as in figure 1, concrete process is as follows: control the adsorption equipment stop work on two walking main units, drive flexible swing arm 4 through drive arrangement afterwards and remove towards the direction of keeping away from steel web 2 and adjust it to vertical state from being in the horizontality, control flexible swing arm 4's flexible afterwards, make the walking main unit of installing in its both ends contradict again in the bridge roof, on the lower plate (as shown in figure 1, the adsorption equipment stop work on the steerable walking subunit this moment, no longer need it to provide the adsorption affinity), workman control walking main unit work afterwards and then realize the device and remove under the spacing of steel web 2, bridge roof, lower plate (whole process need not too much manual operation of workman and need not carry out any dismantlement to this positioner).
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 wheels, 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 wall of the steel web 2, the power wheel 9 is still spaced from the side wall of the steel web 2 by a certain distance (as shown in fig. 8, the device is adsorbed on the steel web 2 by 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 top plate and the 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 steel web 2 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 steel web 2 (as shown in fig. 8).
as shown in fig. 5, after the worker connects and fixes two adjacent steel webs 2 by high-strength bolts and performs permanent welding by 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 steel webs 2 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 to enable the power wheel 9 and the auxiliary wheel 10 arranged on the mounting rack 8 to be 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 from the position in fig. 1 to the position in fig. 14 (namely, the auxiliary wheel 10 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 screws the screw 12 and extends the sub-frame 11 contracted from the walking frame 1 outward, as shown in fig. 14, so that the sub-wheel 13 mounted on the sub-frame 11 moves forward along the side wall of the flange plate 29 at the upper end of the steel web 2 which has been already fixedly connected (preferably, the sub-wheel 13 can move to the middle position of the steel web 2), at which time the worker controls the suction device provided on the sub-wheel 13 to start working again (at which time the suction device on the movable sub-wheel 13 sucks the steel web 2), at which time the other sub-wheel 13 on the sub-frame 11 fixedly mounted with the walking frame 1 abuts against the side wall of the flange plate 29 at the upper end of the steel web 2 which has been completely mounted, under the cooperation of the two sub-frames 11 and the sub-wheel 13 mounted on the sub-frame 11, further assistance of the steel web 2 which has been bolted and welded can be achieved, the steel web plates 2 are strengthened and positioned, so that the situation that the steel web plates 2 shake due to large windward areas of the steel web plates 2 when strong wind or strong convection weather is met in the subsequent steel bar bundling and concrete pouring processes (because only one side of each steel web plate 2 is connected with the steel web plate 2 which is poured with concrete, the other end of each steel web plate is still in an unfixed state), and the connection and fixed parts between every two adjacent steel web plates 2 are damaged (bolts are distorted and deformed or cracks appear at the welded parts);
at this time, the two traveling frames 1 are equivalent to a cross frame positioned between the upper top plate, the lower bottom plate and the two steel web plates 2 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 upper top plate and the lower bottom plate of the bridge) and the auxiliary frames 11 fixedly arranged with the traveling frames 1 (abut against the side walls of the flange plates 29 of the steel web plates 2 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 contact with the steel web plates 2 to be poured with concrete are taken as bodies of the cross frames (the matched telescopic swing arms 4, the traveling frames 1 and the fixedly arranged auxiliary frames 11), so that reliable positioning in the vertical direction and the direction perpendicular to the side walls of the steel web plates 2 is realized.
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 limiting rods 15 to move, i.e. the two limiting rods 15 will not move in the above process (after the two limiting rods 15 are inserted into the limiting holes 16 under the action of the expansion spring 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 to rotate reversely, the round table 5 in threaded fit with the rotating motor 7 is driven by the lead screw to move towards the direction away from the steel web 2 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 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 21, and the limiting rod 15 is driven synchronously to move towards 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 limiting rod 15 inserted into the limiting hole 16 also moves towards the direction away from the steel web 2 along with the action of the intermediate gear 22 during the movement of the round table 5 towards the direction away from the steel web 2 (as long as the limiting rod 15 does not move away from the reverse rotation of the limiting hole 16, the round table 5 can continue to move towards the direction away from the steel web 2 along with the direction of the driving of the steel web 2);
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 state, 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, excessive 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.
Example 7, on the basis of example 4, as shown in fig. 10, the auxiliary wheel 10 includes a rotating shaft 24 rotatably mounted at both ends of the mounting frame 8, and a plurality of segments 25 are slidably mounted on the rotating shaft 24 along a radial direction thereof, the electromagnet 14 is disposed in the segment 25, when the segments 25 are gathered together, the diameter of the auxiliary wheel 10 is the same as that of the power wheel 9, when a worker controls the telescopic swing arm 4 to move toward the direction close to the steel web 2, before the side wall of the auxiliary wheel 10 does not collide with the side wall of the steel web 2, the worker controls the plurality of segments 25 gathered together to expand outward, that is, the state in fig. 5 is switched to the state in fig. 10, and finally, as shown in fig. 9, the expansion of the segments 25 constituting the auxiliary wheel 10 is performed in order to increase the area of the side wall of the steel web 2 covered when the auxiliary wheel 10 contacts with the side wall of the steel web 2, because the auxiliary wheel 10 is composed of the plurality of electromagnets 25 and the segments 25 are provided with the electromagnet 14, when the area of the side wall of the auxiliary wheel 10 contacting with the steel web 2 is increased, the area of the side wall of the electromagnet is increased, which is helpful for increasing the stability of the attraction of the steel web 2 (when the attraction of the steel web 2);
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, namely, in the process of switching from the state shown in figure 1 to the state shown in figure 9, as shown in fig. 15, the worker may synchronously control the power wheel 9 to reversely rotate by an angle (the angle is satisfied: after the driving plate 27 rotates by the angle, the plurality of segments 25 can be expanded outward to the maximum) and accompanying the reverse rotation of the power wheel 9 (the power wheel 9 shaft rotates in the counterclockwise direction), the one-way shaft 34 is driven to rotate counterclockwise synchronously, 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 set of toothed pulleys 31 in the counterclockwise direction as viewed in figure 15, further, the driving plate 27 is driven to rotate relative to the rotating shaft 24 (preferably, a brake for locking the two rotating shafts 24 is arranged on the mounting bracket 8, that is, the rotating shaft 24 is clasped by the brake, so that when the toothed belt wheel set 31 drives the driving plate 27 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 here, a person skilled in the art can obtain the brake according to the prior art and in combination with the present solution), the rotation of the driving plate 27 is accompanied by a plurality of driving rods 28 to drive a plurality of sector blocks 25 which are installed to slide radially along the rotating shaft 24 to expand outwards and switch from the state shown in fig. 5 to the state shown in fig. 11, and at this time, the torsion spring arranged 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 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, namely, to rotate clockwise as shown in fig. 15 (at this time, the brake should keep the state of braking the rotating shaft 24), and along with the clockwise rotation of the power wheel 9, the drive plate 27 will rotate clockwise as shown in fig. 15 under the action of the torsion spring, so that the sector blocks 25 are gathered together again after the drive plate 27 rotates reversely by a corresponding angle, namely, as shown in fig. 5 (at this time, 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 on the rotating shaft 24, and during the subsequent clockwise rotation process of the power wheel 9 as shown in fig. 15, namely, the process of forward walking of the rotating shaft 24 is carried out.
