Description

Technical Field

[0001] The invention belongs to the field of building construction equipment, and in particular relates to a longitudinal beam self-span-changing bearing machine and a self-span-changing moving method for high-altitude construction on a plurality of adjacent building support pedestals. Background Art

[0002] Nowadays, many construction projects are built in specific geographical environments, such as docks on the side of mountains or islands, platforms of elevated transportation hubs, platforms of high-rise towers, elevated bridges, elevated building platforms in mountainous areas, and many other buildings with special construction needs. In the construction process of this type of building, it is necessary to pre-build many supporting pedestals or piers with a certain height and a certain distance between them, and then carry out the installation and construction of prefabricated parts on these multiple adjacent supporting pedestals or piers. The installation and construction of prefabricated parts on these supporting pedestals, the transfer of materials and equipment between pedestals, the construction of building platforms, etc. are all carried out on supporting pedestals with a certain height and a certain distance between them, and the tools, parts, equipment and building materials used need to be transferred in the air many times.

[0003] At present, the tools, equipment and building materials used in this aerial transportation are mostly constructed by ground cranes in combination with temporary steel structures or scaffolding. This method is limited in construction site conditions under specific geographical environments such as river and sea water, tidal flats, cols, busy urban traffic areas, and connecting adjacent elevated buildings. It is necessary to build temporary construction projects such as auxiliary roads, temporary trestles, auxiliary engineering equipment foundations, large-scale cofferdams, or take measures such as large-scale and long-term traffic interruption, increasing the multiple transfer and use time of large-scale ground engineering equipment, resulting in a large increase in the amount of construction auxiliary engineering and construction costs, slow construction progress, long cycle, low efficiency, many construction personnel, and high construction safety risks. In particular, when there are many changes in the location, height and direction of the construction, frequent round-trip operations from the high-altitude operation site to the ground will greatly delay the construction period, increase safety risks, and increase engineering equipment and construction costs. These are problems that are difficult to solve and must be faced by such construction projects.

[0004] The present invention can provide a kind of equipment which is convenient for high-altitude construction work. The equipment can continuously carry out construction work on multiple adjacent building support pedestals. It is a self-span-changing longitudinal beam carrier and a self-span-changing movement method which can complete the transfer and installation of prefabricated building parts, equipment parts, machinery and materials on adjacent building support pedestals. It can effectively solve the problems caused by the current construction methods such as using a large number of temporary construction facilities and using a large number of ground lifting and transportation equipment for a long time. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an equipment that is convenient for high-altitude construction operations. The equipment can continuously carry out construction operations on multiple adjacent building support pedestals. It is a self-span-changing longitudinal beam carrier and a self-span-changing movement method that can complete the transfer and installation of prefabricated building parts, equipment parts, machinery and materials on adjacent building support pedestals.

[0006] The self-span-changing longitudinal beam carrier and the self-span-changing moving method of the present invention mainly include a main beam, a rear-flip support frame, a self-span-changing lower support frame A, a self-span-changing lower support frame B, a beam top self-span support frame, a beam side support frame stabilizing seat, a rear end channel groove, a front end channel groove, a folding roller frame and rollers, a bearing platform, a bearing power vehicle, a mobile operating platform, a rotating device, a control cabinet, a power group, a driving sprocket and a chain, wherein the rear-flip support frame, the self-span-changing lower support frame A, the self-span-changing lower support frame B, and the beam top self-span support frame connected below the main beam each have a supporting cylinder for changing the length of each support frame itself, and can stand on multiple supporting pedestals.

[0007] The rear flip support frame is located below the tail of the main beam, and is hinged to the tail of the main beam and rotates around the connection point, so that the rear flip support frame can flip backward to be parallel to the main beam;

[0008] The self-supporting frame on the top of the beam is a double-legged semi-circular mechanical structure straddling the top surface of the main beam. The bottom of the upper crossbeam of the self-supporting frame on the top of the beam has a power wheel group running on the top surface of the main beam, so that the self-supporting frame on the top of the beam can move longitudinally along the main beam by itself. The two legs fixedly connected to the upper crossbeam span the two sides of the main beam. Each leg is divided into an upper half of the leg and a lower half of the leg. The upper half of the leg and the lower half of the leg are hinged, and the lower half of the leg can be axially rotated outward at the hinge point until it stops at a position where it forms an acute angle with the two side surfaces of the main beam.

[0009] The two side steel plates of the main beam are fixedly installed with a plurality of beam side support frame stabilizing seats along the longitudinal direction. When the inner sides of the two legs of the beam top self-supporting frame straddling the main beam clamp the beam side support frame stabilizing seats at a certain position on both sides of the main beam, the beam top self-supporting frame supports the main beam or lifts and lowers to adjust the height of the main beam with the help of the beam side support frame stabilizing seats. When the inner sides of the two legs of the beam top self-supporting frame straddling the main beam release the clamped beam side support frame stabilizing seats, the lifting and lowering and forward and backward movement of the main beam are not hindered by the surrounding beam top self-supporting frame.

[0010] A self-propelled lower support frame A and a self-propelled lower support frame B are installed below the main beam. The self-propelled lower support frame A and the self-propelled lower support frame B are hung at the edge of the bottom plate of the main beam through the power roller groups at their upper ends. The power roller groups include support wheels and hanging wheels. The support wheels at the lower part of the power roller groups can support the bottom surface of the main beam to roll and move on the support wheels. When the main beam is fixed, the self-propelled lower support frame A and the self-propelled lower support frame B retract their respective support cylinders to shorten their lengths, and can move longitudinally along the main beam through the hanging wheels of the power roller groups. When the self-propelled lower support frame A and the self-propelled lower support frame B are anchored to the support pedestal, and the load-bearing pedestal is temporarily locked with the self-propelled lower support frame A or the self-propelled lower support frame B together with the load-bearing power vehicle, the main beam can be controlled to move longitudinally on the support wheels of the power roller groups at their upper ends along the self-propelled lower support frame A and the self-propelled lower support frame B with the help of the power group, control cabinet, driving sprocket and chain of the load-bearing power vehicle.

[0011] A load-bearing power vehicle that can move longitudinally is installed above the main beam. An independent power group, a control cabinet, a driving sprocket and a chain are installed on the load-bearing power vehicle. The control cabinet and the power group can control the driving sprocket and the chain so that the load-bearing power vehicle can move accurately on the main beam. Several supporting oil cylinders are installed on the upper part of the load-bearing power vehicle, and the load-bearing power vehicle can be locked with the cross-loaded load-bearing platform.

[0012] When several supporting cylinders on the upper part of the load-bearing power vehicle are raised and lowered at the same time, the load-bearing platform locked with the upper part of the load-bearing power vehicle can be raised and lowered relative to the main beam. The load-bearing platform is in the shape of a "J" along the longitudinal cross section. The load-bearing platform can move along the longitudinal direction of the main beam synchronously with the load-bearing power vehicle. Construction machinery and tools such as folding arm cranes, pile drivers, and concrete pump trucks can be installed on the top surface of the load-bearing platform. The load-bearing platform straddles the symmetrical platform on both sides of the main beam and can carry construction and transportation machinery and tools, building materials, prefabricated workpieces, small equipment, etc.

[0013] The lower part of the middle of the main beam is fixedly connected with a slewing device, and the lower part of the slewing device can be temporarily connected with the middle part of the upper end of the self-propelled lower support frame B. The middle part of the self-propelled lower support frame B is equipped with a telescopic cylinder to adjust the height of the self-propelled lower support frame B to ensure that it can be in contact with or connected to the slewing device. When the slewing device is connected to the self-propelled lower support frame B, the anchoring of the self-propelled lower support frame A is released, and the respective supporting cylinders of the back-flip support frame, the self-propelled lower support frame A, and the self-propelled support frame on the top of the beam are folded, and the main beam can rely on the slewing device to achieve horizontal rotation;

[0014] The power roller group installed on the upper beam of the self-propelled lower support frame B can move horizontally along the upper beam of the self-propelled lower support frame B. The position of the power roller group on the upper beam of the self-propelled lower support frame B can be adjusted by means of the telescopic cylinder installed in the middle of the upper beam, and then the horizontal position of the main beam carried by the power roller group on the self-propelled lower support frame B can be adjusted, thereby changing the longitudinal deflection angle of the main beam;

[0015] The front and rear ends of the main beam are respectively provided with upper and lower through holes, the front through hole of the main beam is a front channel groove, and the rear through hole of the main beam is a rear channel groove, the front channel groove and the rear channel groove are channels that can be used to lift building materials, tools, self-parts and components, self-driving lower support frame A, and self-driving lower support frame B from the bottom of the main beam, and the positions of the through holes are on the longitudinal center line of the main beam;

[0016] The folding roller frame and the roller are located at the front end of the main beam. When the main beam is transported longitudinally at the head and tail ends of the high-altitude building to be built supported by the support pedestal, the folding roller frame and the roller can be placed under the main beam to reduce the sliding between the main beam and the platform or the ground at the head and tail ends of the high-altitude building to be built and maintain the rolling motion state;

[0017] The mobile operating platform is surrounded on the main beam, and workers can be moved up and down on the mobile operating platform, and equipment can be inspected or construction can be carried out.

[0018] The longitudinal beam self-span-changing carrier and the self-span-changing moving method of the present invention can realize longitudinal movement between support pedestals with different longitudinal distances and spans on multiple adjacent building support pedestals. The specific moving steps are as follows:

[0019] a. When the longitudinal position of the self-span-changing longitudinal beam carrier needs to be changed, the lowermost ends of the self-span-changing lower support frame A or the self-span-changing lower support frame B are respectively anchored to the upper surface of the support pedestal. The load-bearing power vehicle on the main beam is moved through the control cabinet and the power group, so that the tail end of the load-bearing platform carried by the load-bearing power vehicle is located above the main beam at the self-span-changing lower support frame A or the self-span-changing lower support frame B, and then the load-bearing platform carried by the load-bearing power vehicle is anchored to the self-span-changing lower support frame A or the self-span-changing lower support frame B;

[0020] After that, the supporting oil cylinder of the rear flip support frame is released and retracted, so that the rear flip support frame leaves the upper surface of the supporting pedestal to facilitate the forward movement of the main beam;

[0021] b. Control the driving sprocket and chain to rotate in the opposite direction through the control cabinet of the load-bearing power vehicle on the main beam and under the load-bearing platform, so that the main beam moves forward longitudinally along the support wheels of the power roller group at the upper end of the self-propelled lower support frame A and the support wheels of the power roller group at the upper end of the self-propelled lower support frame B under the fixed load-bearing platform and the load-bearing power vehicle, until the rear flip support frame on the main beam moves to the construction waiting position above the next support pedestal, and the longitudinal movement of the main beam stops;

[0022] c. The back-flip support frame extends the support cylinder to reach the upper surface of the support seat to be used and supports it firmly. The beam top self-supporting frame moves forward along the main beam until it is above the next support seat to be used. The support cylinder of the beam top self-supporting frame is extended to reach the upper surface of the support seat and supports it firmly;

[0023] d. Release the fixing of the load-bearing frame on the upper end of the self-propelled lower support frame A or the self-propelled lower support frame B, and then release the anchoring of the self-propelled lower support frame A or the self-propelled lower support frame B and the upper surface of the support pedestal;

[0024] Contract the support cylinder of the self-propelled lower support frame B and move the self-propelled lower support frame B longitudinally until it is above the next support pedestal to be used, and extend the support cylinder of the self-propelled lower support frame B to reach the upper surface of the front support pedestal and anchor it;

[0025] Then, the self-supporting frame A is anchored to the upper surface of the supporting pedestal, the supporting cylinder of the self-supporting frame A is retracted and the self-supporting frame A is longitudinally moved to the top of the next supporting pedestal to be used, and the supporting cylinder of the self-supporting frame A is extended to reach the upper surface of the supporting pedestal and anchored;

[0026] e. The load-bearing power vehicle moves the load-bearing platform to the top of the self-propelled lower support frame A, and then fixes the load-bearing platform carried by the load-bearing power vehicle above the self-propelled lower support frame A, so that the load-bearing platform is anchored to the self-propelled lower support frame A;

[0027] f. Repeat the above steps to realize the longitudinal movement of the longitudinal beam self-span variable carrier between support pedestals with different span distances.

[0028] The self-span-changing longitudinal beam carrying machine and the self-span-changing moving method of the present invention can realize the overall height change of the main beam carrying the carrying frame relative to the supporting pedestal on multiple adjacent building supporting pedestals. The specific lifting steps are as follows:

[0029] a. When the height position of the longitudinal beam self-propelled variable span load-bearing machine relative to multiple support pedestals needs to be changed, the rear flip support frame and the self-propelled lower support frame A under the main beam stand on one support pedestal, the self-propelled support frame on the top of the beam and the self-propelled lower support frame B stand on another support pedestal, the self-propelled lower support frame A and the self-propelled lower support frame B are anchored to the upper surface of the support pedestal respectively, and the load-bearing power vehicle carries the load-bearing pedestal to the tail end of the main beam. In order to increase the height of the main beam, the anchoring with the self-propelled lower support frame A and the upper surface of the support pedestal is first released;

[0030] b. When the self-propelled lower support frame B is anchored to the upper surface of the support pedestal, the beam top self-propelled support frame and the beam side support frame stabilizing seat are locked, and the support cylinders of the self-propelled lower support frame B and the rear flip support frame are controlled to extend, so that the height of the main beam is raised. At this time, the self-propelled lower support frame A and the self-propelled upper support frame hanging under the main beam are lifted away from the upper surface of the support pedestal as the main beam is lifted. The support cylinders of the rear flip support frame and the self-propelled lower support frame B are extended until they are higher than the height of the pad support and then stop rising;

[0031] c. Place the padding support under the self-propelled lower support frame A and fix it on the upper surface of the support base, and then anchor the lower end of the self-propelled lower support frame A on the fixed padding support;

[0032] d. Place the padding support under the beam top self-supporting frame and fix it on the upper surface of the support pedestal, and then firmly support the lower end of the beam top self-supporting frame on the padding support;

[0033] e. Release the anchoring of the lower end of the self-propelled lower support frame B and the upper surface of the support pedestal, retract the support cylinders of the back-flip support frame and the self-propelled lower support frame B, so that the lower ends of the back-flip support frame and the self-propelled lower support frame B leave the upper surface of the support pedestal, and stop raising when the height exceeds the height of the pad support;

[0034] f. Place the padding support pieces under the rear flip support frame and the self-propelled lower support frame B respectively and fix them on the upper surface of the support pedestal. Then anchor the lower end of the self-propelled lower support frame B on the fixed padding support pieces. The rear flip support frame is stably supported on the padding support pieces below it.

[0035] g. Repeat the above steps to gradually increase the height of the longitudinal beam self-span variable carrier on the supporting pedestal.

[0036] The longitudinal beam self-span-changing carrier and the self-span-changing moving method of the present invention can be used for high-altitude construction operations on multiple adjacent building support pedestals, and can realize on-site steering and U-turning at the center of the self-driving lower support frame B on multiple support pedestals. The specific on-site steering and U-turning action steps are as follows:

[0037] a. When the longitudinal beam self-span changeable carrier needs to turn and reverse on the spot, the lowermost ends of the self-propelled lower support frame A and the self-propelled lower support frame B under the main beam are anchored to the upper surface of the support pedestal respectively, and the load-bearing power vehicle on the main beam is moved to make the tail end of the load-bearing platform carried by the load-bearing power vehicle move to the top of the self-propelled lower support frame B, and then the load-bearing platform carried by the load-bearing power vehicle is anchored to the self-propelled lower support frame B;

[0038] The control cabinet of the load-bearing power vehicle on the main beam and under the load-bearing platform controls the movement of the driving sprocket and the chain, so that the main beam moves longitudinally along the power roller groups on the upper ends of the self-propelled lower support frame A and the self-propelled lower support frame B, until the slewing device below the middle of the main beam moves to the upper end of the self-propelled lower support frame B, and the slewing device is connected to the middle of the upper end of the self-propelled lower support frame B;

[0039] b. Contract the supporting oil cylinder of the beam top self-supporting frame to make the bottom end of the beam top self-supporting frame leave the upper surface of the supporting pedestal and reach a suspended state;

[0040] c. Move and adjust the position of the self-supporting frame on the top of the beam and the mobile operating platform on the main beam until the main beam meets the required position of symmetrical balance of the loads of the longitudinal components with the slewing device as the center;

[0041] d. Release the anchoring between the lower end of the self-propelled lower support frame A and the upper surface of the support pedestal, retract the support cylinders of the self-propelled lower support frame A and the rear flip support frame, so that the rear half of the main beam is suspended in the air, and adjust the self-propelled lower support frame A along the longitudinal direction of the main beam until it stops moving above the required support pedestal, so as to achieve and maintain the symmetrical balance state of the loads of the longitudinal components of the main beam with the slewing device as the center;

[0042] e. Control the rotation device below the middle of the main beam to rotate until the main beam reaches the required angle, stop turning, extend the support cylinders of the self-propelled lower support frame A and the self-propelled support frame on the top of the beam until they reach the upper surface of the support pedestal, anchor the self-propelled lower support frame A to the upper surface of the support pedestal, and complete the turning of the main beam;

[0043] f. Release the anchoring between the lower end of the self-propelled lower support frame B and the upper surface of the support pedestal, retract the support cylinder of the self-propelled lower support frame B, make the lower end of the self-propelled lower support frame B leave the upper surface of the support pedestal, start the slewing device under the middle of the main beam to rotate the self-propelled lower support frame B, and stop rotating after the self-propelled lower support frame B rotates to the required position, and extend the support cylinder of the self-propelled lower support frame B until it reaches the upper surface of the support pedestal and then anchors;

[0044] g. Release the matching connection between the slewing device at the lower middle part of the main beam and the upper end of the self-propelled lower support frame B, move the load-bearing platform carried by the load-bearing power vehicle to the upper end of the self-propelled lower support frame A, and then fix the load-bearing platform to the upper end of the self-propelled lower support frame A, so that the load-bearing platform is anchored to the self-propelled lower support frame A;

[0045] By controlling the load-bearing power vehicle, the main beam is longitudinally moved and adjusted to a suitable position along the upper ends of the self-propelled lower support frame A and the self-propelled lower support frame B under the fixed load-bearing platform, and the anchoring of the load-bearing platform and the self-propelled lower support frame A is released, completing the steering work of the entire longitudinal beam self-propelled variable span load-bearing machine;

[0046] h. Repeat the above steps to realize the next turning operation of the longitudinal beam self-span-changing carrier on the supporting pedestal.

[0047] The self-span-changing longitudinal beam carrier and the self-span-changing moving method of the present invention can greatly reduce the amount of temporary construction projects. In specific geographical environments such as rivers and seas, tidal flats, cols, busy urban traffic areas, and connecting elevated buildings, when the conditions on the construction site are restricted, the self-span-changing longitudinal beam carrier can be used to place and carry building materials, workpieces, special engineering equipment, machinery and personnel, and can carry out high-altitude transportation, installation and maintenance operations. The carrier equipment itself can arbitrarily move longitudinally, increase height, turn, and other construction problems on the supporting pedestals of adjacent buildings. The self-span-changing longitudinal beam carrier and the self-span-changing moving method of the present invention, wherein the main beam can be placed on the top platform of the high column, because the main beam is fixed with a steering device below it, and after the main beam rotates, the platform has a wide range of movement, which can be involved in the fan-shaped area, and has high flexibility. The front and rear ends of the main beam of the present invention are respectively provided with a front channel groove and a rear channel groove with upper and lower through holes, which are convenient passages for lifting building materials, tools, and small equipment. The position of the through hole is on the longitudinal center line of the main beam, which can ensure that the center of gravity does not shift when transporting various materials, thereby increasing safety and improving the efficiency of transporting materials. A load-bearing power vehicle that can move longitudinally is installed above the main beam. The load-bearing power vehicle carries a load-bearing platform, which can control the drive sprocket and chain through the control cabinet and the power group so that the load-bearing power vehicle can move longitudinally accurately on the main beam. Various tools, building materials, and small equipment can be placed on the load-bearing platform, and it can also serve as a support frame for the longitudinal movement of the main beam, with one design and multiple functions. The mobile operating platform surrounds the main beam, and workers can be moved up and down, as well as equipment inspection or construction can be carried out through the mobile operating platform, which increases personnel safety and facilitates equipment maintenance.

[0082] like Figure 1 As shown, Figure 1The three-dimensional view of the longitudinal beam self-span variable carrier of the present invention. The main structure of the longitudinal beam self-span variable carrier of the present invention includes a main beam 1, a rear flip support frame 2, a self-span lower support frame A3, a self-span lower support frame B4, a beam top self-span support frame 5, a beam side support frame stabilizing seat 6, a rear end channel groove 7, a front end channel groove 8, a folding roller frame and rollers 9, a load-bearing platform 10, a load-bearing power vehicle 11, a mobile operating platform 12, a slewing device 13, a control cabinet 14, a power group 15, a driving sprocket and a chain 17, wherein the rear flip support frame 2, the self-span lower support frame A3, the self-span lower support frame B4, and the beam top self-span variable carrier 5 connected below the main beam 1 each have a supporting cylinder 26 for changing the length of each support frame, and can stand on multiple supporting platforms 16. The rear flip support frame 2 is located below the tail of the main beam 1, and the rear flip support frame 2 is hinged to the tail of the main beam 1 and rotates with the connection as the axis, so that the rear flip support frame 2 can be flipped backward to be parallel to the main beam 1.

[0083] like Figure 2 As shown, Figure 2 This is a front view of the longitudinal beam self-span-changing carrier of the present invention. The folding roller frame and roller 9 are located at the front end of the main beam 1. When the main beam 1 is transported longitudinally, the folding roller frame and roller 9 can be placed under the main beam 1, so that the main beam 1 does not directly contact the ground and maintains a rolling motion state, reducing the resistance of the main beam (1) when moving; on the two side steel plates of the main beam 1, a plurality of beam side support frame stabilizing seats 6 are fixedly installed along the longitudinal direction.

[0084] A self-propelled lower support frame A3 and a self-propelled lower support frame B4 are installed below the main beam 1 . The self-propelled lower support frame A3 and the self-propelled lower support frame B4 are hooked to the bottom of the main beam 1 through the power roller groups 23 at their upper ends.

[0085] The lower middle part of the main beam 1 is fixedly connected to the slewing device 13, and the lower part of the slewing device 13 can be temporarily connected with the middle part of the upper end of the self-propelled lower support frame B4. The middle part of the self-propelled lower support frame B4 is equipped with a telescopic cylinder 27 to adjust the height of the self-propelled lower support frame B4 to ensure that it can be in contact with or connected to the slewing device 13. When the slewing device 13 is connected to the self-propelled lower support frame B4, the main beam 1 can rely on the slewing device 13 to achieve horizontal rotation.

[0086] like Figure 3 As shown, Figure 3 It is a top view of the longitudinal beam self-span variable carrier of the present invention. The front and rear ends of the main beam 1 are respectively provided with upper and lower through holes, the front through hole of the main beam 1 is the front channel groove 8, and the rear through hole of the main beam 1 is the rear channel groove 7. The front channel groove 8 and the rear channel groove 7 are channels that can be used to lift building materials, tools, self-parts and components, self-supporting lower support frame A3, and self-supporting lower support frame B4 from the bottom of the main beam 1, and the position of the through holes is on the longitudinal center line of the main beam 1.

[0087] like Figure 4 As shown, Figure 4 The AA cross-sectional view of the longitudinal beam self-span variable carrier of the present invention. The power roller group 23 includes a support wheel 24 and a hanging wheel 25. The support wheel 24 at the lower part of the power roller group 23 can support the bottom surface of the main beam 1 to roll on the support wheel 24. When the main beam 1 is fixed, the self-supporting lower support frame B4 retracts the support cylinder 26 to shorten the length, and can move longitudinally along the main beam 1 through the hanging wheel 25 of the power roller group 23.

[0088] When the self-propelled lower support frame B4 is anchored on the support pedestal 16, and the load-bearing pedestal 10 and the load-bearing power vehicle 11 are temporarily locked with the self-propelled lower support frame B4, with the help of the power group 15, the control cabinet 14, the driving sprocket and the chain 17 of the load-bearing power vehicle 11, the main beam 1 can be controlled to move longitudinally on the support wheel 24 of the power roller group 23 at the upper end of the self-propelled lower support frame B4.

[0089] The power roller group 23 installed on the upper crossbeam 18 of the self-propelled lower support frame B4 can be moved horizontally along the upper crossbeam 18 of the self-propelled lower support frame B4. The position of the power roller group 23 on the upper crossbeam 18 of the self-propelled lower support frame B4 can be adjusted with the help of the telescopic cylinder 27 installed in the middle of the upper crossbeam 18, and then the horizontal position of the main beam 1 carried by the power roller group 23 on the self-propelled lower support frame B4 can be adjusted, thereby changing the longitudinal deflection angle of the main beam 1.

[0090] like Figure 5 As shown, Figure 5 The movable operating platform 12 surrounds the main beam 1, and workers can go up and down the movable operating platform 12, and equipment can be inspected or constructed.

[0091] like Figure 6 As shown, Figure 6 The CC cross-sectional view of the longitudinal beam self-span variable carrier of the present invention. The power roller group 23 includes a support wheel 24 and a hanging wheel 25. The support wheel 24 at the lower part of the power roller group 23 can support the bottom surface of the main beam 1 to roll on the support wheel 24. When the main beam 1 is fixed, the self-propelled lower support frame A3 retracts the support cylinder 26 to shorten the length, and can move longitudinally along the main beam 1 through the hanging wheel 25 of the power roller group 23. When the self-propelled lower support frame A3 is anchored on the support pedestal 16, the main beam 1 can be controlled to move longitudinally on the support wheel 24 of the power roller group 23 at the upper end of the self-propelled lower support frame A3 with the help of the power group 15, the control cabinet 14, the driving sprocket and the chain 17 of the load-bearing power vehicle 11.

[0092] The load-bearing gantry 10 has a "U" shape in the longitudinal cross-section. The load-bearing gantry 10 can move longitudinally along the main beam 1 synchronously with the locked load-bearing power vehicle 11. Construction tools such as folding boom cranes, pile drivers, and concrete pump trucks can be installed on the top surface of the load-bearing gantry 10. The load-bearing gantry 10 straddles the symmetrical platforms on both sides of the main beam 1 and can carry construction transport tools, building materials, precast workpieces, small equipment, etc.

[0093] As Figure 7 shown, Figure 7 This is the D-D sectional view of the longitudinal beam self-variable span load-bearing machine of the present invention. The rear flip support frame 2 is located below the tail of the main beam 1, and the rear flip support frame 2 is hinged to the tail of the main beam 1 and rotates about the connection point, so that the rear flip support frame 2 can be flipped backward to be perpendicular to the main beam 1. Among them, the rear flip support frame 2 connected below the main beam 1 has a support oil cylinder 26 for changing its own length and can stand on the support pedestal 16.

[0094] The longitudinal beam self-variable span load-bearing machine of the present invention can realize longitudinal movement between the support pedestals 16 with different longitudinal distances and spans on multiple adjacent building support pedestals. As Figures 8 to 12 an example, the specific moving steps are described in detail as follows:

[0095] As Figure 8 shown, Figure 8 This is the schematic diagram of Step 1 when the longitudinal beam self-variable span load-bearing machine of the present invention moves forward. When it is necessary to change the longitudinal position of the longitudinal beam self-variable span load-bearing machine, the lowermost ends of the self-propelled lower support frame A3 and the self-propelled lower support frame B4 are respectively anchored to the upper surface of the support pedestal 16. The load-bearing power vehicle 11 on the main beam 1 is moved through the control cabinet 14 and the power unit 15, so that the tail end of the load-bearing gantry 10 carried by the load-bearing power vehicle 11 is located directly above the self-propelled lower support frame B4, and then the load-bearing gantry 10 carried by the load-bearing power vehicle 11 is anchored to the self-propelled lower support frame B4; thereafter, the support oil cylinder 26 of the rear flip support frame 2 is released and contracted, so that the rear flip support frame 2 leaves the upper surface of the support pedestal 16 to facilitate the forward movement of the main beam 1.

[0096] As Fig. 9 shown, Fig. 9 This is the schematic diagram of Step 2 when the longitudinal beam self-variable span load-bearing machine of the present invention moves forward. The control cabinet 14 of the load-bearing power vehicle 11 on the main beam 1 and under the load-bearing gantry 10 controls the reverse rotation of the drive sprocket and chain 17, so that the main beam 1 moves longitudinally forward along the support wheels 24 of the power roller group 23 at the upper end of the self-propelled lower support frame A3 and the support wheels 24 of the power roller group 23 at the upper end of the self-propelled lower support frame B4 until the beam top self-supporting frame 5 and the rear flip support frame 2 on the main beam 1 move to their respective next support pedestals 16.

[0097] As Fig.10 shown, Fig.10 This is a schematic diagram of step 3 of the longitudinal beam self-span-changing carrier moving forward. The rear tilt support frame 2 extends the support cylinder 26 to reach the upper surface of the support seat 16 to be used and supports it firmly. The beam top self-supporting frame 5 moves forward along the main beam 1 until it is above the next support seat 16 to be used. The support cylinder 26 of the extended beam top self-supporting frame 5 reaches the upper surface of the support seat 16 and supports it firmly.

[0098] like Fig.11 As shown, Fig.11 It is a schematic diagram of step 4 when the longitudinal beam self-span changing carrier of the present invention moves forward. The fixing of the carrier frame 10 on the upper end of the self-span lower support frame A3 is released, and then the anchoring of the self-span lower support frame A3 and the self-span lower support frame B4 with the upper surface of the support base 16 is released respectively;

[0099] Contract the supporting cylinder 26 of the self-propelled lower support frame B4 and move the self-propelled lower support frame B4 longitudinally until it is above the next support pedestal 16 to be used, and extend the supporting cylinder 26 of the self-propelled lower support frame B4 to reach the upper surface of the support pedestal 16 and anchor it;

[0100] Then, the supporting cylinder 26 of the self-supporting frame A3 is retracted and the self-supporting frame A3 is longitudinally moved until it is above the next supporting pedestal 16 to be used, and the supporting cylinder 26 of the self-supporting frame A3 is extended to reach the upper surface of the supporting pedestal 16 and anchored.

[0101] like Fig.12 As shown, Fig.12 This is a schematic diagram of step 5 when the longitudinal beam self-span changing carrier of the present invention moves forward. The main beam 1 moves forward and backward in the longitudinal direction, stops moving after reaching the predetermined position, and the load-bearing power vehicle 11 moves with the load-bearing platform 10 to the top of the self-sustaining lower support frame A3, and then fixes the load-bearing platform 10 carried by the load-bearing power vehicle 11 above the self-sustaining lower support frame A3, so that the load-bearing platform 10 is anchored to the self-sustaining lower support frame A3.

[0102] Repeat the above Figures 8 to 12 The steps shown can realize the gradual longitudinal movement of the longitudinal beam self-span-changing carrier between the support pedestals 16 with different span distances.

[0103] The self-span-changing longitudinal beam load-bearing machine of the present invention can realize the overall height change of the main beam 1 carrying the load-bearing frame 10 relative to the support pedestal 16 on multiple adjacent building support pedestals 16, such as Figures 13 to 18 Taking the figure as an example, the specific steps of lifting the longitudinal beam self-span variable load-bearing machine are as follows:

[0104] like Fig.13 As shown, Fig.13It is a schematic diagram of step 1 of the raising of the longitudinal beam self-span variable carrier of the present invention. When the height position of the longitudinal beam self-span variable carrier as a whole relative to the multiple support pedestals 16 needs to be changed, the rear flip support frame 2 and the self-span lower support frame A3 under the main beam 1 stand on one support pedestal 16, the beam top self-span support frame 5 and the self-span lower support frame B4 stand on another support pedestal 16, the self-span lower support frame A3 and the self-span lower support frame B4 are anchored to the upper surface of the support pedestal 16 respectively, and the load-bearing power vehicle 11 carries the load-bearing pedestal 10 to move to the tail end of the main beam 1. In order to raise the height of the main beam 1, the anchoring of the self-span lower support frame A3 and the self-span lower support frame 5 on the upper surface of the support pedestal 16 is first released.

[0105] like Fig.14 As shown, Fig.14 It is a schematic diagram of step 2 of the longitudinal beam self-span variable carrier when the present invention is raised. When the self-supporting lower support frame B4 is anchored to the upper surface of the support pedestal 16, the self-supporting frame 5 on the top of the beam is locked with the stabilizing seat 6 of the beam side support frame, and the support cylinders 26 of the self-supporting lower support frame B4 and the rear flip support frame 2 are controlled to extend, so that the height of the main beam 1 is raised. At this time, the self-supporting lower support frame A3 hanging below the main beam 1 and the self-supporting frame 5 on the top of the beam are lifted away from the upper surface of the support pedestal 16 with the main beam 1, and the support cylinders 26 of the rear flip support frame 2 and the self-supporting lower support frame B4 are extended until they are higher than the height of the pad support 28 and then stop rising.

[0106] like Fig.15 As shown, Fig.15 The schematic diagram of step 3 of the longitudinal beam self-span variable carrier of the present invention is as follows: the raising support member 28 is placed under the self-span lower support frame A3 and fixed on the upper surface of the support pedestal 16, and then the lower end of the self-span lower support frame A3 is anchored on the fixed raising support member 28.

[0107] like Fig.16 As shown, Fig.16 The schematic diagram of step 4 of the longitudinal beam self-span variable carrier of the present invention is as follows: the raising support member 28 is placed under the beam top self-supporting frame 5 and fixed on the upper surface of the support pedestal 16, and then the lower end of the beam top self-supporting frame 5 is anchored on the fixed raising support member 28.

[0108] like Fig.17 As shown, Fig.17 The schematic diagram of step 5 of the present invention is a schematic diagram of the raising of the longitudinal beam self-span variable carrier. The anchoring of the bottom ends of the rear flip support frame 2 and the self-span lower support frame B4 to the upper surface of the support pedestal 16 is released, and the support cylinders 26 of the rear flip support frame 2 and the self-span lower support frame B4 are retracted to make the bottom ends of the rear flip support frame 2 and the self-span lower support frame B4 leave the upper surface of the support pedestal 16, and the raising is stopped when the height exceeds the height of the pad support 28.

[0109] like Fig.18 As shown, Fig.18 The figure is a schematic diagram of step 6 of the longitudinal beam self-span variable carrier raising of the present invention. The heightening support members 28 are respectively placed under the rear flip support frame 2 and the self-span lower support frame B4 and fixed on the upper surface of the support pedestal 16, and then the lower ends of the rear flip support frame 2 and the self-span lower support frame B4 are anchored on the fixed heightening support members 28.

[0110] Repeat the above Figures 13 to 18 The steps shown can realize the gradual increase of the height of the longitudinal beam self-span variable carrier on the support pedestal 16.

[0111] like Fig.19 As shown, Fig.19 This is a top view schematic diagram of the longitudinal beam self-span-changing carrier of the present invention when rotating, showing the position change during the entire rotation process.

[0112] The longitudinal beam self-span variable load-bearing machine of the present invention can be used for high-altitude construction operations on multiple adjacent building support pedestals 16, and can realize on-site steering and U-turning with the center of the self-sustaining lower support frame B4 on multiple support pedestals 16. Now, the steering of the main beam 1 and the load-bearing pedestal 10 between the support pedestals 16 is used as an example for explanation. Figures 20 to 29 As shown in the figure, the specific steps of the on-site turning and U-turn of the longitudinal beam self-span-changing carrier are as follows:

[0113] like Fig. 20 As shown, Fig. 20 This is a schematic diagram of step 1 of the rotation of the longitudinal beam self-span variable carrier of the present invention. When the longitudinal beam self-span variable carrier needs to turn and reverse on the spot, the lowermost ends of the self-span lower support frame A3 and the self-span lower support frame B4 under the main beam 1 are anchored to the upper surface of the support pedestal 16 respectively, and the load-bearing power vehicle 11 on the main beam 1 is moved so that the tail end of the load-bearing platform 10 carried by the load-bearing power vehicle 11 moves to the top of the self-span lower support frame A3, and then the load-bearing platform 10 carried by the load-bearing power vehicle 11 is anchored to the self-span lower support frame A3;

[0114] The movement of the driving sprocket and the chain 17 is controlled by the control cabinet 14 of the power vehicle 11 on the main beam 1 and under the load-bearing platform 10, so that the main beam 1 moves longitudinally along the power roller groups 23 on the upper ends of the self-propelled lower support frame A3 and the self-propelled lower support frame B4, until the rotating device 13 at the lower middle part of the main beam 1 moves to the upper part of the self-propelled lower support frame B4, and the rotating device 13 is connected to the middle part of the upper end of the self-propelled lower support frame B4.

[0115] like Fig.21 As shown, Fig.21The schematic diagram of step 2 of the rotation of the longitudinal beam self-span-changing carrier of the present invention is as follows. The anchoring of the carrying platform 10 carried by the carrying power vehicle 11 and the self-propelled lower support frame A3 is released, and the carrying power vehicle 11 on the main beam 1 is moved so that the carrying power vehicle 11 and the carrying platform 10 move above the self-propelled lower support frame B4, and the supporting cylinder 26 of the beam top self-propelled support frame 5 itself is retracted so that the bottom end of the beam top self-propelled support frame 5 leaves the upper surface of the support pedestal 16 and reaches a suspended state.

[0116] like Fig. 22 As shown, Fig. 22 The schematic diagram of step 3 of the present invention is that the longitudinal beam self-span-changing carrier rotates. The self-supporting frame 5 and the mobile operating platform 12 on the main beam 1 are moved and adjusted until the loads of the longitudinal components of the main beam 1 reach a symmetrical balance with the slewing device 13 as the center.

[0117] like Fig.23 As shown, Fig.23 The schematic diagram of step 4 of the present invention is that the longitudinal beam self-span-changing carrier rotates. The anchoring between the bottom end of the self-span lower support frame A3 and the upper surface of the support pedestal 16 is released, and the support cylinders 26 of the self-span lower support frame A3 and the rear flip support frame 2 are retracted, so that the rear half of the main beam 1 is suspended in the air, and the loads of the longitudinal components of the main beam 1 are achieved and maintained in a symmetrical balance state with the slewing device 13 as the center.

[0118] like Fig.24 , Fig.25 As shown, Fig.24 This is a schematic diagram of step 5 of the present invention when the longitudinal beam automatically changes the span of the carrier and rotates. Fig.25 The top view of this step is shown in FIG. The slewing device 13 at the lower middle part of the main beam 1 is controlled to rotate until the main beam 1 reaches the required angle and stops turning. Then the self-supporting lower frame A3 and the self-supporting frame 5 on the top of the beam are adjusted longitudinally along the main beam 1 until they are above the required support pedestal 16 and stop moving. The support cylinders 26 of the self-supporting lower frame A3 and the self-supporting frame 5 on the top of the beam are extended until they reach the upper surface of the support pedestal 16. The self-supporting lower frame A3 is anchored to the upper surface of the support pedestal 16 to complete the turning of the main beam 1.

[0119] like Fig.26 , Fig. 27 As shown, Fig.26 This is a schematic diagram of step 6 of the present invention when the longitudinal beam automatically changes the span of the carrier and rotates. Fig. 27The top view of this step is as follows. The anchoring between the bottom end of the self-propelled lower support frame B4 and the upper surface of the support pedestal 16 is released, and the support cylinder 26 of the self-propelled lower support frame B4 is retracted to make the bottom end of the self-propelled lower support frame B4 leave the upper surface of the support pedestal 16. The rotating device 13 below the middle of the main beam 1 is started to rotate the self-propelled lower support frame B4 until the self-propelled lower support frame B4 is rotated to the desired position and then stops rotating. The support cylinder 26 of the self-propelled lower support frame B4 is extended until it reaches the upper surface of the support pedestal 16 and then anchors.

[0120] like Fig.28 , Fig.29 As shown, Fig.28 This is a schematic diagram of step seven of the present invention when the longitudinal beam automatically changes span when the carrier rotates. Fig.29 The top view of this step is to release the matching connection between the slewing device 13 at the lower middle part of the main beam 1 and the upper end of the self-propelled lower support frame B4, move the load-bearing platform 10 carried by the load-bearing power vehicle 11 to the upper end of the self-propelled lower support frame A3, and then fix the load-bearing platform 10 on the upper end of the self-propelled lower support frame A3, so that the load-bearing platform 10 is anchored to the self-propelled lower support frame A3;

[0121] By controlling the load-bearing power vehicle 11, the main beam 1 is longitudinally moved and adjusted to a suitable position along the upper ends of the self-propelled lower support frame A3 and the self-propelled lower support frame B4 under the fixed load-bearing platform 10, and the anchoring of the load-bearing platform 10 and the self-propelled lower support frame A3 is released, completing the steering work of the entire longitudinal beam self-propelled variable span load-bearing machine.

[0122] Repeat the above Figures 20 to 29 The steps shown can realize the next turning operation of the longitudinal beam self-span-changing carrier on the supporting pedestal 16.

[0123] like Fig.30 As shown, Fig.30 It is the EE cross-sectional view of the longitudinal beam self-span-changing load-bearing machine of the present invention. A load-bearing power vehicle 11 that can move longitudinally is installed above the main beam 1. The load-bearing power vehicle 11 is equipped with an independent power group 15, a control cabinet 14, a driving sprocket and a chain 17. The control cabinet 14 and the power group 15 can control the driving sprocket and the chain 17 so that the load-bearing power vehicle 11 can move accurately on the main beam 1. The upper part of the load-bearing power vehicle 11 is equipped with several supporting oil cylinders 26, and the load-bearing power vehicle 11 can be locked with the cross-loaded load-bearing platform 10; when the several supporting oil cylinders 26 on the upper part of the load-bearing power vehicle 11 are raised and lowered at the same time, the load-bearing platform 10 locked with the upper part of the load-bearing power vehicle 11 can be raised and lowered relative to the main beam 1.

[0124] like Fig.31 As shown, Fig.31The schematic diagram of the rotation state of the lower half of the legs of the beam top self-supporting frame of the longitudinal beam self-span variable carrier of the present invention. The beam top self-supporting frame 5 is a double-leg semi-circular mechanical structure straddling the top surface of the main beam 1. The bottom of the upper crossbeam 18 of the beam top self-supporting frame 5 has a power wheel set 19 running on the top surface of the main beam 1, so that the beam top self-supporting frame 5 can move longitudinally along the main beam 1 by itself. The two legs fixedly connected to the upper crossbeam 18 are straddling the two sides of the main beam 1. Each leg is divided into an upper leg part 20 and a lower leg part 21. The upper leg part 20 and the lower leg part 21 are hinged. The lower leg part 21 can rotate axially outward at the hinge point 22 until it stops at a position where it forms an acute angle with the two side surfaces of the main beam 1.

[0125] When the inner sides of the two legs of the beam top self-supporting frame 5 spanning the main beam 1 clamp the beam side support frame stabilizing seat 6 somewhere on both sides of the main beam, the beam top self-supporting frame 5 supports the main beam 1 or raises or lowers the height of the main beam 1 with the help of the beam side support frame stabilizing seat 6; when the inner sides of the two legs of the beam top self-supporting frame 5 spanning the main beam 1 release the clamped beam side support frame stabilizing seat 6, the lifting and lowering and forward and backward movement of the main beam 1 are not hindered by the surrounding beam top self-supporting frame 5.

[0126] The embodiments described above are merely descriptions of preferred implementation modes of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by those skilled in the art should all fall within the protection scope of the claims of the present invention.
