Description

Technical Field

[0001] The present invention relates to the technical field of bridge engineering, and particularly to a girder hoisting support for a crane on a non-guide girder jacking platform for steel girders. Background Art

[0002] The non-guide girder jacking construction of a steel girder means that during the jacking process of the steel girder, instead of using the traditional leading girder structure, the self-structural characteristics of the steel girder and some auxiliary devices are utilized to achieve the jacking and positioning of the steel girder. This method usually involves setting some temporary supports and jacking devices on the steel girder, and through the jacking equipment set on the abutment or pier, the steel girder is jacked forward section by section. During the jacking process, the self-rigidity and strength of the steel girder are utilized to resist various forces during the jacking process. At the same time, through precise measurement and control technologies, the jacking accuracy and stability of the steel girder are ensured. The non-guide girder jacking platform for steel girders bears the entire weight of the steel girder during the jacking process, ensuring the stability of the steel girder during movement and preventing excessive deformation or subsidence due to the action of gravity. Moreover, the non-guide girder jacking platform for steel girders also provides a certain construction operation surface, facilitating the operation of construction personnel and construction machinery. During the construction process of the steel girder, the operation of the crane on the steel girder plays a key role. Since there is usually a certain height difference between the end of the steel girder and the ground, when the crane loads the girder, it usually climbs onto the platform at the end of the steel girder jacking platform using a hoisting support, and the hoisting support is usually set as a ramp-type support.

[0003] However, in the prior art, the following problems exist:

[0004] The existing hoisting supports are usually assembled on-site using steel structures to match the height difference between the end of the steel girder and the ground. Since the height differences between the ends of steel girders and the ground are different for different bridge engineering projects, after the completion of a project, the hoisting support is usually demolished. When constructing the next bridge project, it is necessary to reassemble a suitable hoisting support according to the actual on-site situation, resulting in a low utilization rate of the existing hoisting support. For each project, a new hoisting support needs to be reassembled, increasing the cost. At the same time, the assembly of the hoisting support also occupies some operation time, thus affecting the construction progress. Summary of the Invention

Detailed implementation manners

[0033] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope protected by the present invention.

[0034] Embodiment 1

[0035] Please refer to Figure 1 - Figure 11 , which includes a chassis 1. A triangular frame 2 is hinged on the chassis 1. A slope panel 3 is connected to the triangular frame 2. Two hydraulic cylinders 6 are hinged on the chassis 1. The output ends of the two hydraulic cylinders 6 are both hinged to the bottom of the triangular frame 2. A plurality of cushion blocks 10 are connected to the bottom of the triangular frame 2. The bottom surfaces of the plurality of cushion blocks 10 are all in contact with the top surface of the chassis 1. The plurality of cushion blocks 10 make a certain gap between the bottom of the triangular frame 2 and the chassis 1, enabling the two hydraulic cylinders 6 to be inclined. The output ends of the hydraulic cylinders 6 are inclined upward. The slope panel 3 is inclined. The lower end of the slope panel 3 is hinged with a boarding plate 4. Four lifting lugs 5 are connected to the outer wall of the triangular frame 2. There are lifting holes on the lifting lugs 5. The lifting holes of the four lifting lugs 5 are on the same horizontal plane. The crane hoists the triangular frame 2 through the four lifting lugs 5. The chassis 1, the triangular frame 2, and the slope panel 3 are an integral whole. The setting of the four lifting lugs 5 facilitates hoisting. The two hydraulic cylinders 6 jack up the triangular frame 2 through the output ends. The whole hydraulic cylinders 6 rotate following the lifting of the triangular frame 2, enabling the triangular frame 2 to swing upward with its hinge point with the chassis 1 as the center. The slope panel 3 moves synchronously with the triangular frame 2, causing the angle between the slope panel 3 and the chassis 1 to continuously increase, thus achieving the effect of adjusting the angle of the slope panel 3. Through the setting of the two hydraulic cylinders 6, a certain range of angle adjustment can be carried out between the triangular frame 2 and the chassis 1, thus achieving the effect of adjusting the slope of the slope panel 3, enabling the slope panel 3 to adapt to the bridge ends of different heights, thereby meeting different engineering projects, improving the utilization rate of the slope panel 3 and the triangular frame 2, thus reducing the engineering cost, and the installation and commissioning are relatively convenient. Compared with on-site assembly, a large amount of operation time is saved.

[0036] Furthermore, it also includes a gap filling component 7 for filling the gap between the steel beam and the slope panel 3. The gap filling component 7 includes a mounting cover 71 and a docking plate 72. The mounting cover 71 is connected to the higher end of the slope panel 3. The docking plate 72 is slidably installed on the inner wall of the mounting cover 71. One end of the docking plate 72 is located outside the mounting cover 71. There is a certain gap between the higher end of the slope panel 3 and the top surface of the steel beam. The docking plate 72 in the mounting cover 71 is placed on the end of the steel beam. At this time, the docking of the slope panel 3 and the steel beam is completed. The boarding plate 4 is placed on the ground, facilitating the crane to drive onto the slope panel 3.

[0037] Furthermore, the gap filling component 7 further includes a right-angle rod 73 and a connecting rod 74. The right-angle rod 73 is connected to the bottom surface of the docking plate 72. The right-angle rod 73 is slidably connected through the bottom of the mounting cover 71. One end of the connecting rod 74 is hinged to the end of the right-angle rod 73 away from the mounting cover 71, and the other end of the connecting rod 74 is hinged to the chassis 1. When the tripod 2 is lifted, since the distance between the right-angle rod 73 and the chassis 1 continuously increases, the top of the connecting rod 74 gradually swings to the left, causing the connecting rod 74 to drive the docking plate 72 to move leftward through the right-angle rod 73, so that more parts of the docking plate 72 extend out of the mounting cover 71, thereby extending the docking length of the docking plate 72. Through the setting of the gap filling component 7, the docking plate 72 can be placed on the end of the steel beam to fill the gap between the steel beam and the slope panel 3, achieving the technical effect of docking the steel beam and the slope panel 3. Through the cooperation of the connecting rod 74 and the right-angle rod 73, the docking plate 72 can move leftward and extend as the slope of the slope panel 3 increases, always keeping the left end of the docking plate 72 able to rest on the steel beam, thereby maintaining the docking effect and avoiding a large gap between the steel beam and the slope panel 3 from affecting the passage of the crane.

[0038] In addition, an anti-slip component 8 is used to prevent the crane from slipping on the slope panel 3. The anti-slip component 8 includes a mounting plate 81 and a plurality of anti-slip blocks 82. The plurality of anti-slip blocks 82 are all connected to the top surface of the mounting plate 81. A set of anti-slip ridges are provided on the anti-slip blocks 82. A plurality of sets of through grooves are provided on the slope panel 3. The anti-slip ridges on the plurality of anti-slip blocks 82 are respectively slidably connected to the plurality of sets of through grooves. The plurality of sets of anti-slip ridges all protrude from the top surface of the slope panel 3. The mounting plate 81 plays a role in mounting and connecting the plurality of anti-slip blocks 82. After the anti-slip ridges on the plurality of anti-slip blocks 82 protrude from the slope panel 3, an anti-slip surface is formed, which can increase the friction between the wheels and the slope panel 3 when the crane passes, thereby avoiding wheel slippage and improving the safety of the crane passing.

[0039] In addition, the anti-slip component 8 further includes two slide rail frames 83, a sliding frame 84 and a plurality of sliding shafts 86. Both of the two slide rail frames 83 are mounted on the tripod 2. The sliding frame 84 is slidably connected between the two slide rail frames 83. A plurality of inclined slots 85 are formed in the sliding frame 84. A plurality of sliding shafts 86 are respectively connected to the bottom surface of the mounting plate 81 through brackets. The plurality of sliding shafts 86 are respectively slidably connected through the plurality of inclined slots 85. When the plurality of inclined slots 85 on the sliding frame 84 move leftward, they can drive the plurality of sliding shafts 86 to move upward, so that the protruding height of the multiple groups of anti-slip ridges on the slope panel 3 increases, the anti-slip effect of the anti-slip ridges increases, and the frictional force generated when the wheels pass also increases. Thus, the effect that the multiple groups of anti-slip ridges can automatically improve the anti-slip effect following the increase of the slope of the slope panel 3 is achieved. Through the arrangement of the anti-slip component 8, the anti-slip ridges on the multiple anti-slip blocks 82 can protrude from the surface of the slope panel 3, thereby playing an anti-slip role and preventing the wheels from slipping when the crane passes; through the cooperation of the sliding frame 84 and the plurality of sliding shafts 86, the multiple anti-slip blocks 82 can move upward with the increase of the slope of the slope panel 3, increasing the protruding height of the anti-slip ridges, so as to achieve the effect of improving the anti-slip performance, and enabling the anti-slip performance of the multiple anti-slip blocks 82 to be adaptively adjusted following the slope of the slope panel 3.

[0040] It should be noted that the anchoring component 9 is used to anchor the chassis 1 to the ground. The anchoring component 9 includes two supports 91, two pry bars 92, a mounting shaft 93, a plurality of anchoring hooks 94 and a smooth rod 95. Both of the two supports 91 are mounted on the chassis 1. The two pry bars 92 are respectively rotatably connected to the two supports 91. The smooth rod 95 is connected to the bottom surface of the tripod 2 through a bracket. The mounting shaft 93 is connected to the two pry bars 92. A plurality of anchoring hooks 94 are all connected to the outer wall of the mounting shaft 93. A chute is provided at one end of the pry bar 92 away from the mounting shaft 93. The smooth rod 95 is slidably connected through the chutes of the two pry bars 92. The smooth rod 95 can be drawn out within its mounting bracket and the chutes of the two pry bars 92. The plurality of anchoring hooks 94 are arranged in a linear array. When the smooth rod 95 moves upward, it drives the mounting shaft 93 to swing downward through the two pry bars 92 by using the lever principle. The mounting shaft 93 drives the plurality of anchoring hooks 94 to move downward. When the plurality of anchoring hooks 94 move downward, they can be inserted into the ground, thereby increasing the stability of the chassis 1 on the ground. Through the arrangement of the anchoring component 9, the plurality of anchoring hooks 94 can be inserted into the soil when the tripod 2 is lifted, and as the lifting angle of the tripod 2 increases, the insertion depth of the anchoring hooks 94 also increases accordingly, thereby improving the stability of the tripod 2 and the chassis 1.

[0041] It should be noted that the anchoring assembly 9 further includes an elastic strip 96 and a sawtooth strip 97. The elastic strip 96 is connected to the outer wall of the mounting shaft 93, and the sawtooth strip 97 is connected to the chassis 1. The sawtooth strip 97 is provided with a sawtooth surface. When the elastic strip 96 moves, it makes sliding contact with the sawtooth surface of the sawtooth strip 97. When the elastic strip 96 moves, it contacts the sawtooth surface of the sawtooth strip 97 and vibrates. Through the arrangement of the elastic strip 96 and the sawtooth strip 97, multiple anchoring hooks 94 can vibrate during the process of being inserted into the soil, so that the insertion process of the anchoring hooks 94 is smoother.

[0042] With the above structure, the working principle of this case is that the beam support on the gantry crane without a guide beam for jacking the steel beam is prefabricated in advance. After being transported to the construction site, first use a crane to hoist the tripod 2 through four lifting lugs 5. The chassis 1, the tripod 2, and the slope panel 3 are an integral body. The arrangement of the four lifting lugs 5 facilitates hoisting. After the tripod 2 is moved close to the end of the steel beam, place the chassis 1 on the ground. At this time, start to adjust the slope of the slope panel 3. Multiple cushion blocks 10 make there be a certain gap between the bottom of the tripod 2 and the chassis 1, so that the two hydraulic cylinders 6 can be inclined. The output ends of the hydraulic cylinders 6 are inclined upward. Start the two hydraulic cylinders 6. The two hydraulic cylinders 6 jack up the tripod 2 through the output ends. The whole hydraulic cylinder 6 rotates following the lifting of the tripod 2, so that the tripod 2 can swing upward around its hinge point with the chassis 1. The slope panel 3 moves synchronously with the tripod 2, so that the angle between the slope panel 3 and the chassis 1 continuously increases, thus achieving the effect of adjusting the angle of the slope panel 3. When the higher end of the slope panel 3 is slightly higher than the end of the steel beam, use a forklift or a fork truck to push the chassis 1 towards the end of the steel beam, so that the tripod 2 and the chassis 1 abut against the lower part of the end of the steel beam. At this time, there is still a certain gap between the higher end of the slope panel 3 and the top surface of the steel beam. The butt plate 72 in the installation cover 71 is placed on the end of the steel beam. At this time, the butt joint between the slope panel 3 and the steel beam is completed. The bridging plate 4 is placed on the ground, which is convenient for the crane to drive onto the slope panel 3. The crane can climb onto the steel beam through the slope panel 3, and it is also convenient for construction workers and other construction machinery to get on and off the steel beam; through the arrangement of the two hydraulic cylinders 6, a certain range of angle adjustment can be carried out between the tripod 2 and the chassis 1, so as to achieve the effect of adjusting the slope of the slope panel 3, so that the slope panel 3 can adapt to the bridge ends of different heights, thus meeting different engineering projects, improving the utilization rate of the slope panel 3 and the tripod 2, thereby reducing the engineering cost, and the installation and debugging are relatively convenient. Compared with on-site assembly, a large amount of operation time is saved.

[0043] As the slope of the slope panel 3 increases, the projected length of the slope panel 3 on the ground will gradually be less than the length of the chassis 1. Therefore, the gap between the slope panel 3 and the end of the steel beam also increases. The top of the connecting rod 74 is inclined to the right. While the tripod 2 is lifted, due to the continuous increase in the distance between the right-angle rod 73 and the chassis 1, the top of the connecting rod 74 gradually swings to the left, causing the connecting rod 74 to drive the docking plate 72 to move leftward through the right-angle rod 73, so that more parts of the docking plate 72 extend out of the mounting cover 71, thereby extending the docking length of the docking plate 72, enabling the docking plate 72 to move leftward and extend as the slope of the slope panel 3 increases, and always keeping the left end of the docking plate 72 able to rest on the steel beam, thus filling the gap between the steel beam and the slope panel 3 and preventing the wheels from getting stuck in the gap when the crane travels; through the setting of the gap-filling component 7, the docking plate 72 can rest on the end of the steel beam, filling the gap between the steel beam and the slope panel 3, achieving the technical effect of docking the steel beam and the slope panel 3. Through the cooperation of the connecting rod 74 and the right-angle rod 73, the docking plate 72 can move leftward and extend as the slope of the slope panel 3 increases, always keeping the left end of the docking plate 72 able to rest on the steel beam, thereby maintaining the docking effect and preventing a large gap between the steel beam and the slope panel 3 from affecting the passage of the crane.

[0044] The mounting plate 81 serves to mount and connect multiple anti-slip blocks 82. After the anti-slip ridges on the multiple anti-slip blocks 82 protrude from the slope panel 3, an anti-slip surface is formed, which can increase the friction between the wheels and the slope panel 3 when the crane passes, thus avoiding wheel slippage and improving the safety of the crane passing. As the slope of the slope panel 3 increases, the sliding frame 84 can slide left and right on the two slide rail frames 83. When the right-angle rod 73 moves left, it drives the sliding frame 84 to move left. The multiple sliding shafts 86 slide along the inclined surfaces of the multiple inclined slots 85. When the multiple inclined slots 85 on the sliding frame 84 move left, they can drive the multiple sliding shafts 86 to move up. Conversely, when the inclined slots 85 move right, they can drive the sliding shafts 86 to move down. When the multiple sliding shafts 86 move up, they jack up the mounting plate 81 upward through the bracket. The mounting plate 81 drives the multiple anti-slip blocks 82 to move up, so that the anti-slip ridges on the multiple anti-slip blocks 82 slide upward in the multiple through slots of the slope panel 3, increasing the protruding height of the multiple anti-slip ridges on the slope panel 3, increasing the anti-slip effect of the anti-slip ridges, and also increasing the friction generated when the wheels pass, thus achieving the effect that the multiple anti-slip ridges can automatically improve the anti-slip effect following the increase in the slope of the slope panel 3. Similarly, when the slope of the slope panel 3 is relatively low, the upward movement distance of the multiple anti-slip blocks 82 is also relatively low. While meeting the anti-slip performance, the protruding height of the anti-slip ridges is reduced as much as possible, which can reduce the bumpiness when the crane passes and also reduce the wear of the anti-slip blocks 82. And when the anti-slip blocks 82 move down, the dirt adhering to the anti-slip ridges can be scraped off by the through slots, playing a role in cleaning the anti-slip ridges and avoiding a large amount of dirt adhering around the anti-slip ridges after long-term use, thus reducing the anti-slip effect; through the setting of the anti-slip component 8, the anti-slip ridges on the multiple anti-slip blocks 82 can protrude from the surface of the slope panel 3, thus playing an anti-slip role and avoiding wheel slippage when the crane passes; through the cooperation of the sliding frame 84 and the multiple sliding shafts 86, the multiple anti-slip blocks 82 can move up as the slope of the slope panel 3 increases, increasing the protruding height of the anti-slip ridges, thus achieving the effect of improving the anti-slip performance and enabling the anti-slip performance of the multiple anti-slip blocks 82 to be adaptively adjusted following the slope of the slope panel 3.

[0045] When the tripod 2 is lifted, it drives the polished rod 95 to move upward. The pry bar 92 can swing around the support 91 as the center. When the polished rod 95 moves upward, it drives the mounting shaft 93 to swing downward through the lever principle by means of two pry bars 92. The mounting shaft 93 drives a plurality of anchoring hooks 94 to move downward. When the plurality of anchoring hooks 94 move downward, they can be inserted into the ground, thereby increasing the stability of the chassis 1 on the ground. When the slope of the slope panel 3 is relatively large, when the crane travels on the slope panel 3, the overall center of gravity of the crane and the tripod 2 is relatively high. At this time, the risk of the tripod 2 shaking is greater. As the lifting angle of the tripod 2 increases, the insertion depth of the anchoring hooks 94 also increases accordingly. By inserting the plurality of anchoring hooks 94 deeper into the ground, the stability of the tripod 2 and the chassis 1 can be further increased, and the risk of the tripod 2 shaking can be reduced. The polished rod 95 can be withdrawn from its mounting bracket and the chutes of the two pry bars 92. When the chassis 1 is placed on the hardened ground, since the anchoring hooks 94 cannot be inserted into the hardened ground, after the polished rod 95 is withdrawn, the two pry bars 92 do not swing when the tripod 2 moves upward; when the mounting shaft 93 moves, it drives the elastic strip 96 to move synchronously. When the elastic strip 96 moves, it contacts the tooth surface of the sawtooth strip 97 and vibrates. The elastic strip 96 transmits the vibration to the mounting shaft 93, so that the mounting shaft 93 drives a plurality of anchoring hooks 94 to vibrate. The plurality of anchoring hooks 94 can promote their insertion into the soil through vibration, and avoid deformation due to excessive resistance when inserted into relatively hard soil; through the setting of the anchoring assembly 9, the plurality of anchoring hooks 94 can be inserted into the soil when the tripod 2 is lifted, and as the lifting angle of the tripod 2 increases, the insertion depth of the anchoring hooks 94 also increases accordingly, thereby improving the stability of the tripod 2 and the chassis 1; through the setting of the elastic strip 96 and the sawtooth strip 97, the plurality of anchoring hooks 94 can vibrate during the process of being inserted into the soil, so that the insertion process of the anchoring hooks 94 is smoother.

[0046] As described above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
