Description

Technical Field

[0001] The invention relates to the technical field of bridge demolition, and in particular to a bridge demolition construction equipment. Background Art

[0002] A steel bridge is a temporary bridge, usually made of steel, used to temporarily build bridges across rivers, roads, etc. Its main function is to temporarily solve traffic or passage problems when the old bridge is demolished and a new bridge is built. It is also suitable for emergency repairs, maintenance, emergency rescue and other scenarios after disasters.

[0003] The service life of a steel temporary bridge is usually short, and it will usually be dismantled after a new bridge is built. When dismantling a steel temporary bridge, the Bailey frames installed parallel to the bottom of the bridge need to be dismantled one by one. As the Bailey frames are continuously dismantled, the supporting force of the bridge deck will change, which may easily cause the bridge deck to tilt to one side as a whole, posing a safety hazard. When the Bailey frames are installed on the bridge deck, a row of I-beams are usually laid and welded on the Bailey frames to ensure the strength of the bridge. Common installation methods are shown in the attached manual. Fig. 9 However, when the last Bailey frame is dismantled, the rows of I-beams are only connected to it at the ends. If the last Bailey frame is directly dismantled, there is a safety problem of the I-beams sliding off. If the rows of I-beams are dismantled one by one first, the entire dismantling progress will be slow. Therefore, a bridge dismantling construction equipment is proposed. Summary of the invention

[0020] Example, see Figures 1 to 9 A bridge demolition construction equipment comprises a demolition fixing seat 1 and a demolition angle grinder 2 for destroying the welding point between the Bailey frame and the I-beam, a receiving groove is provided on the demolition fixing seat 1, an installation groove for installing a control motor 3 is provided on the inner end surface of the storage groove, and an output end of the control motor 3 is connected to an electric control guide rail 5 for adjusting the push-out of the demolition angle grinder 2 through a steering wheel 4; Furthermore, the output end of the control motor 3 is fixedly connected to the top of one end of the electric control rail 5 through the steering wheel 4, and the inner wall of the electric control rail 5 is fixedly connected to the handle of the dismantling angle grinder 2 through the slide seat; It should be noted that after the fixing seat 1 is removed and fixed, the steering wheel 4 is driven to deflect at an angle by the control motor 3, so as to control the deflection position of the electric control guide rail 5, thereby adjusting the cutting angle of the removal angle grinder 2, and at the same time, the removal angle grinder 2 is moved and changed on the electric control guide rail 5 to adjust the cutting distance of the removal angle grinder 2; The above advantages are: in this way, after removing the limit of the fixing seat 1, the welding points between the Bailey frame and the I-beam in different angles can be cut and destroyed, so that the Bailey frames can be removed from the steel temporary bridge one by one; The top of the removal fixing seat 1 is respectively connected to a plurality of inverted suction cups 7 through a plurality of electrically controlled lifting columns 6, and a fixing seat assembly for fixing to the bottom end of the bridge is arranged in the inverted suction cup 7; Further, the number of the plurality of electrically controlled lifting columns 6 is four, and they are respectively located at the four corners of the top of the dismantled fixed seat 1, the top of the electrically controlled lifting column 6 is fixedly connected to the bottom of the inverted suction cup 7, the fixed seat assembly is composed of a plurality of pneumatic push rods 8 and a plurality of limiting arc plates 9, the top of the electrically controlled lifting column 6 is respectively fixedly connected to the outer side walls of the plurality of limiting arc plates 9 through the plurality of pneumatic push rods 8, the plurality of limiting arc plates 9 are arranged in a circular array, the top of the electrically controlled lifting column 6 is provided with an electric connection groove, a fixed metal rod 10 is arranged in the electric connection groove, the outer side wall of the top of the fixed metal rod 10 is fixedly connected with a welding ring 11, and the welding ring 11 is made of welding rod material; It should be noted that: first, the inverted suction cup 7 on the electric-controlled lifting column 6 is pressed against the bottom surface of the bridge, and then a large current is provided to the fixed metal rod 10 through the power connection slot at the top of the electric-controlled lifting column 6, so that the welding ring 11 of the welding rod material at the top thereof melts under the action of the high current, and the fixed metal rod 10 and the steel surface at the bottom end of the bridge are adhered, so that the fixed metal rod 10 is welded to the steel at the bottom end of the bridge. During the welding process, the oxygen in the inverted suction cup 7 is consumed, so that the inverted suction cup 7 can be firmly adsorbed on the bottom surface of the bridge, making the limit between the removal fixing seat 1 and the steel plane more stable, and making the removal of the fixed limit between the fixing seat 1 and the bridge faster. When separation is required, the pneumatic push rod 8 is used to cancel the push on the limit arc plate 9, so that the limit arc plate 9 loses the pressure on the fixed metal rod 10, which facilitates the separation of the fixed metal rod 10 from the electric-controlled lifting column 6; The above advantages are: in this way, the removal fixing seat 1 and the steel plane on the steel temporary bridge can be quickly and stably fixed and limited, which is convenient for flexibly coping with the removal work of different parts of the steel temporary bridge, making the removal of the steel temporary bridge more efficient; The inner end surface of the receiving groove of the dismantling fixing seat 1 is connected to the bottom support plate 13 through the installation bottom plate 12, and a light measuring component is arranged on one side of the bottom support plate 13. The side wall of the bottom support plate 13 is connected to the lower triangular seat 16, and the lower triangular seat 16 is connected to the upper triangular seat 19 through the upper adjustment plate 17 and the lower adjustment plate 18 respectively. A limit position component is arranged in the upper triangular seat 19, and the top of the upper triangular seat 19 is connected to a platform plate 21, and the top of the platform plate 21 is connected to two clamping right-angle plates 26; Furthermore, the optical measurement component is composed of an angle laser lamp 14 and a transverse photosensitive plate 15. The end of the angle laser lamp 14 is fixedly connected to the side wall of the storage groove of the removal fixing seat 1, and the bottom end of the transverse photosensitive plate 15 is fixedly connected to the top of the bottom support plate 13. The bottom support plate 13 is located on one side of the angle laser lamp 14 and is provided with a metal mirror. The light beam projected by the angle laser lamp 14 is reflected by the mirror to the transverse photosensitive plate 15. If the pressure-bearing limit structure between the bottom support plate 13 and the platform plate 21 is gradually damaged (elastic deformation process before the metal breaks), the angle of the transverse photosensitive plate 15 will also change, thereby changing the landing point of the reflective optical fiber, which is convenient for detecting the angle change during the pressure-bearing process. A photoelectric sensor for sensing light is provided in the transverse photosensitive plate 15; The lower triangular seat 16 is rotatably connected to the lower ends of the upper adjustment plate 17 and the lower adjustment plate 18 through two pins, and the upper triangular seat 19 is rotatably connected to the upper ends of the upper adjustment plate 17 and the lower adjustment plate 18 through two pins. The limit assembly is composed of a limit plug rod 24 and a fan-shaped limit plate 23. A plurality of limit holes are arranged in an array on the fan-shaped limit plate 23. The inner side wall of the limit hole is slidably connected to the limit plug rod 24. The pin located at the top of the lower triangular seat 16 is connected to the pin located at the bottom of the upper triangular seat 19 through a strong spring 22. The side wall of the upper triangular seat 19 is fixedly connected to the upper support plate 20. The platform plate 21 is rotatably connected to the side wall of the clamping right-angle plate 26 through a hinge 25. The top of the platform plate 21 is fixedly connected to a pressure plate 28 through a telescopic rod 27. A pressure sensor is arranged in the telescopic rod 27. It should be noted that: when the Bailey frame is dismantled, the limit rod 24 is pulled out, and by rotating the pin shaft at the top, the fan-shaped limit plate 23 rotates, and the upper adjustment plate 17 and the lower adjustment plate 18 and the upper triangular seat 19 and the lower triangular seat 16 will present a quadrilateral structure, so as to adjust the height of the platform plate 21. After the adjustment is completed, the limit rod 24 is pushed into the limit hole on the fan-shaped limit plate 23 for re-limiting. At this time, the pressure plate 28 on the telescopic rod 27 is against the bottom end surface of the steel temporary bridge. If the steel temporary bridge has unstable tilting and vibration during the continuous dismantling of the Bailey frame of the steel temporary bridge, the pressure on the pressure plate 28 will change, which will be sensed by the pressure sensor in the telescopic rod 27, so that the on-site construction personnel can detect and make construction adjustments in time. At the same time, when the last Bailey frame is dismantled, the dismantling fixing seat 1 is fixedly installed on the horizontal plane of the internal frame of the Bailey frame, and then the height of the platform plate 21 is adjusted so that the two clamping right-angle plates 26 can be just clamped on the side wall of the I-beam. Then, the last Bailey frame forms a triangular stable structure between the dismantling device and the I-beam, which is convenient for the stable dismantling of the two. The above advantages are: in this way, the last remaining Bailey frame and I-beam can be removed quickly and synchronously, which improves the overall removal efficiency and makes the final removal safer and more reliable; When the present invention is used, the inverted suction cup 7 on the electric-controlled lifting column 6 is first pressed against the bottom surface of the bridge, and then a large current is provided to the fixed metal rod 10 through the power connection slot at the top of the electric-controlled lifting column 6, so that the welding ring 11 of the welding rod material at the top thereof melts under the action of the high current, and the fixed metal rod 10 and the steel surface at the bottom end of the bridge are adhered, so that the fixed metal rod 10 is welded to the steel at the bottom end of the bridge. During the welding process, the oxygen in the inverted suction cup 7 is consumed, so that the inverted suction cup 7 can be firmly adsorbed on the bottom surface of the bridge. The limit between the dismantling fixing seat 1 and the steel plane is made more stable, and the fixed limit between the dismantling fixing seat 1 and the bridge is made faster. When separation is required, the pneumatic push rod 8 is used to cancel the push on the limit arc plate 9, and the limit arc plate 9 loses the pressure on the fixed metal rod 10 to limit the fixed metal rod 10, which is convenient for the separation of the fixed metal rod 10 and the electric control lifting column 6. In this way, the dismantling fixing seat 1 and the steel plane on the steel temporary bridge can be quickly and stably fixed and limited, which is convenient for flexible response to the dismantling work of different parts of the steel temporary bridge, making the dismantling of the steel temporary bridge more efficient. After the fixed limit of the fixed seat 1 is removed, the angle deflection of the steering wheel 4 is driven by the control motor 3, so as to control the deflection position of the electric control guide rail 5, thereby adjusting the cutting angle of the removed angle grinder 2. At the same time, the removed angle grinder 2 is moved and changed on the electric control guide rail 5 to adjust the cutting distance of the removed angle grinder 2. In this way, after the fixed seat 1 is removed, the welding points between the Bailey frame and the I-beam in different angle directions can be cut and destroyed, so that the Bailey frames can be removed from the steel temporary bridge one by one. When the Bailey frame is dismantled, the limit rod 24 is pulled out, and by rotating the pin shaft at the top, the fan-shaped limit plate 23 rotates, and the upper adjustment plate 17 and the lower adjustment plate 18 and the upper triangular seat 19 and the lower triangular seat 16 will form a quadrilateral structure, so as to adjust the height of the platform plate 21. After the adjustment is completed, the limit rod 24 is pushed into the limit hole on the fan-shaped limit plate 23 for re-limiting. At this time, the pressure plate 28 on the telescopic rod 27 is against the bottom end surface of the steel temporary bridge. If the steel temporary bridge has unstable tilt vibration during the continuous dismantling of the Bailey frame of the steel temporary bridge, the pressure on the pressure plate 28 will change, which will be sensed by the pressure sensor in the telescopic rod 27, so that the on-site construction personnel can detect and make construction adjustments in time; At the same time, when the last Bailey frame is dismantled, the dismantling fixing seat 1 is fixedly installed on the horizontal plane of the internal frame of the Bailey frame, and then the height of the platform plate 21 is adjusted so that the two clamping right-angle plates 26 can be just clamped on the side wall of the I-beam. Then, the last Bailey frame forms a triangular stable structure through the dismantling device and the I-beam, which is convenient for stable dismantling of the two. In this way, the last remaining Bailey frame and the I-beam can be quickly dismantled synchronously, which improves the overall dismantling efficiency and makes the final dismantling safer and more reliable.
