For various types of crossing objects, common crossing methods include bamboo crossing frames, steel pipe crossing frames, gantry frames, crane-lifted beams, wire-turning frames, suspension bridge closures, etc.; currently, bamboo crossing frames are widely used for electrified railways, conventional railway highways, national and provincial roads, urban roads, etc. due to their mature technology, wide application range, and low construction difficulty; however, the existing bamboo usually grows from thick to thin, and it is difficult to ensure that the thickness of the bamboo is consistent. In the process of using bamboo to erect crossing frames, it is difficult to bind and fix the joints, and soft iron wires are usually used to bind the bamboo joints during the erection of existing bamboo crossing frames. However, since the surfaces of the iron wire and the bamboo are relatively smooth, the bamboo is prone to loosening during the iron wire binding process, making it difficult for the bamboo crossing frame to be stably supported, thereby posing certain safety hazards.

[0038] It should be noted that if the support assembly 3 is in a folded state initially and needs to be unfolded, pull out the fixing pin of the second pin hole 10, unfold the horn bracket 14 to the position of the pin hole 1 9, insert the fixing pin, and operate the other end in the same way; pull out the fixing pin of the third pin hole 11, unfold the support rod 4 to the position of the pin hole 4 12, insert the fixing pin, fix the support rod 4, and unfold the crossbeam 6; operate the other end in the same way; the folding of the crossbeam 6 and the horn bracket 14 is reversed according to the above process.

[0039] The outermost sleeve of the boom of the crane 1 is provided with a fixing hole 1, and the remaining internal sleeves are all provided with a fixing hole 2. When the boom is extended, the fixing hole 1 is connected with the fixing hole 2 in sequence. The fixing hole 1 and the fixing hole 2 are penetrated by a pin, so that the sleeves can be fixed and the risk of leakage in the oil cylinder in the boom can be reduced.

[0040] The fixing assembly 2 includes a mounting plate 18, a driving assembly 19 and an adjusting assembly 20. The driving assembly 19 is movably arranged on the upper wall of the mounting plate 18. The adjusting assembly 20 is provided in multiple groups. The multiple groups of adjusting assembly 20 are evenly spaced and movably connected to the side wall of the mounting plate 18 in a ring shape. One end of the adjusting assembly 20 is movably connected to the driving assembly 19, and the other end of the adjusting assembly 20 extends out of the side wall of the mounting plate 18.

[0041] The upper wall of the mounting plate 18 is provided with a plurality of groups of slot holes 21 for limiting, and the plurality of groups of slot holes 21 are evenly arranged on the upper wall of the mounting plate 18 in a circular shape. The side wall of the mounting plate 18 is provided with a plurality of groups of slot holes 22 for limiting, and the plurality of groups of slot holes 22 are evenly arranged on the side wall of the mounting plate 18 in a circular shape. The slot holes 22 penetrate the side wall of the mounting plate 18, and the number of the slot holes 22, the number of the slot holes 1 21 and the number of the regulating components 20 are all the same, and the lower end of the slot hole 1 21 is through-connected with the upper end of the slot hole 22.

[0042] The driving assembly 19 includes a motor plate 23, a gear 1 24, a gear 25 and a winding roller 26, wherein the winding roller 26 is arranged at the center of the mounting plate 18, and the gear 2 25 is movably mounted on the upper wall of the mounting plate 18 with the winding roller 26 as the rotation center. The motor plate 23 is arranged on the upper wall of the mounting plate 18, and a motor 27 is installed on the upper wall of the motor plate 23. The gear 1 24 is arranged at the lower end of the mounting plate 18, and the gear 1 24 is movably mounted on the upper wall of the mounting plate 18, and the gear 1 24 and the gear 2 25 are meshed and connected, and the output shaft end of the motor 27 is connected to the center of the gear 1 24; the motor 27 drives the gear 1 24 to rotate when it works, and the gear 1 24 drives the gear 2 25 to rotate.

[0043] The gear 2 25 is provided with a plurality of groups of limit grooves 28 for limiting, and the plurality of groups of limit grooves 28 are evenly arranged on the gear 2 25 in a ring shape and at equal intervals. The limit grooves 28 are arc-shaped structures, and the number of the limit grooves 28 is the same as the number of the regulating components 20.

[0044] The regulating assembly 20 includes a fixed plate 29, a ring member 30 and a regulating limit member 31. A slot four 32 is provided on the upper wall of the ring member 30. The slot four 32 is arranged through the upper wall and the bottom wall of the ring member 30. The fixed plate 29 is movably placed through the slot four 32, and the upper end of the fixed plate 29 is arranged at the upper end of the ring member 30. One end of the regulating limit member 31 is connected to the side wall of the ring member 30, and the other end of the regulating limit member 31 is movably clamped in the slot two 22. A ball is installed between the regulating limit member 31 and the slot two 22 to reduce the friction of the regulating limit member 31 when it moves in the slot two 22.

[0045] The regulating and limiting member 31 has a slot hole 33 on the upper wall, and two limiting grooves 34 are provided on the opposite side walls of the slot hole 33. The slot hole 33 is movably connected with a regulating plate 35, and the side wall of the regulating plate 35 is movably connected in the limiting groove 34. A spring 36 is installed between the bottom wall of the regulating plate 35 and the inner bottom wall of the slot hole 33. A limiting rod 37 is installed on the upper wall of one end of the regulating plate 35 away from the ring member 30. The regulating plate 35 is close to the ring member 30. A pressure rod 38 is installed on the upper wall of one end of the mounting plate 18, and the pressure rod 38 is arranged outside the mounting plate 18. The upper end of the limiting rod 37 is movably sleeved with a sleeve 39, and the limiting rod 37 is movably clamped in the slot 21, and the upper end of the limiting rod 37 extends out of the upper wall of the mounting plate 18, and the sleeve 39 at the upper end of the limiting rod 37 is movably clamped in the limiting groove 28. The setting of the sleeve 39 can reduce the friction between the limiting rod 37 and the limiting groove 28.

[0046] It should be noted that the rotation of gear 25 drives the limit slot 1 28 to rotate. Since the limit slot 1 28 is an arc-shaped structure, when the limit slot 1 28 rotates, it drives the sleeve 39 and the limit rod 37. The limit rod 37 drives the control plate 35 and the control limit member 31 to reciprocate along the slot hole 1 21 and the slot hole 22. When the limit rod 37 pushes the control limit member 31 to move outward along the slot hole 22, the control component 20 is in an outwardly expanded state. When the limit rod 37 pushes the control limit member 31 to move inward along the slot hole 22, the control component 20 is in an inwardly retracted state.

[0047] The upper wall of the fixing plate 29 is provided with a lower pressing plate 40, the side wall of the fixing plate 29 is provided with a through hole 17 for the wire to pass through and a plurality of fixing holes 41 for fixing, and the bottom wall of the lower pressing plate 40 is movably provided with a push rod 42, and the push rod 42 is arranged just above the pressing rod 38;

[0048] It should be noted that when the fixing plate 29 needs to be inserted into the soil to fix the fixing assembly 2, the push rod 42 is fixed to the bottom wall of the lower pressure plate 40 by bolts. When the fixing plate 29 moves down along the slot hole 432 and is inserted into the soil, the lower pressure plate 40 can be driven to move down, and the lower pressure plate 40 drives the push rod 42 to move down. The push rod 42 moves down to the upper end of the pressure rod 38. As the movement continues, the push rod 42 squeezes the pressure rod 38, and the pressure rod 38 drives the regulating plate 35 and the limit rod 37 to enter the slot hole 33, the spring 36 is compressed, and the sleeve 39 is separated from the limit slot 28 and is set in the slot hole 21.

[0049] When the fixing plate 29 is needed to tighten the pull wire, the fixing plate 29 is fixed on the annular member 30, the push rod 42 is removed from the bottom wall of the lower pressure plate 40, the pull wire passes through the through hole 17 and is tied to the winding roller 26. When the pull wire needs to be tightened, the gear 25 rotates to drive the regulating component 20 to move outward, and the through hole 17 on the regulating component 20 moves outward to squeeze the pull wire.

[0050] The side wall of the annular member 30 is also provided with a third fixing hole 43 matching the fixing hole 41 on the fixing plate 29. After the fixing plate 29 is inserted into the fourth slot 32, the fixing hole 41 on the fixing plate 29 coincides with the fixing hole 43 on the annular member 30, and the fixing plate 29 is fixed after the bolt passes through the fixing hole 41 and the fixing hole 43.

[0051] The specific usage is as follows:

[0052] The boom elevation angle of 90° is only used under the condition of stringing wires. When the boom elevation angle reaches 78° during lifting, the extension of the boom cylinder should be stopped when the alarm sounds; park the two wheeled multifunctional mobile crossing frames on both sides of the area that needs to be crossed, and see the operating instructions of crane 1 for specific operations when getting off the vehicle; the operation of the horizontal and vertical legs shall be carried out in accordance with the requirements of crane 1, and after the legs are fully operated, unfold the support assembly 3 according to the following steps; if the support assembly 3 is in a folded state at the beginning and needs to be unfolded, pull out the fixing pin of pin hole two 10, unfold the horn bracket 14 to the position of pin hole one 9, insert the fixing pin, and operate the other end in the same way; pull out the fixing pin of pin hole three 11, unfold the support rod 4 to the position of pin hole four 12, insert the fixing pin, fix the support rod 4, and unfold the crossbeam 6; operate the other end in the same way; the folding of the crossbeam 6 and the horn bracket 14 is reversed according to the above process.

[0053] After the support assembly 3 is unfolded as required above, the main hook is lowered and fixed on the vehicle frame or the ground anchor to serve as an auxiliary pulling force for the boom to prevent the risk of backward tilting when the boom is at 90° (pay attention to the lowering of the hook winch when the boom is changed). The boom changes the arm length to 90° (vertical limit) according to the operating method of part 1 of the crane, and the boom tension wire is fixed to the tension wire hole 5. After tightening the boom tension wire, it is fixed to the ground with the fixing assembly 2 to ensure that it is firmly fixed. In order to avoid high-altitude operations, the tension wire can be fixed to the tension wire hole 5 first, and then the boom is extended to the required height. When the boom is extended, the fixing hole 1 is connected with the fixing hole 2 in sequence, and the fixing hole 1 and the fixing hole 2 are penetrated by a pin, so as to achieve fixation between the sleeves and reduce the risk of leakage in the oil cylinder in the boom; finally, the load-bearing cable is deployed through the installation hole 15 between the support assemblies 3 on both sides, and the capping net is laid to form a shielding channel.

[0054] For different types of spanning construction and different spans and high-speed spanning objects, the height of the spanning frame needs to be adjusted according to the actual situation. Therefore, the main body of the spanning frame has a multi-level height adjustment function, and the spanning heights are 18, 24 and 30 meters respectively. Pull out the fixing pin fixing device on the boom, insert the fixing pin at the required height position, and after the fixing pin is fixed, tighten the crossbeam 6 wire and fix it to the ground with the fixing component 2 to ensure that it is firmly fixed.

[0055] The motor 27 drives the gear 1 24 to rotate, the gear 1 24 drives the gear 2 25 to rotate, the gear 2 25 rotates and drives the limit slot 1 28 to rotate. Since the limit slot 1 28 is an arc structure, when the limit slot 1 28 rotates, it drives the sleeve 39 and the limit rod 37, and the limit rod 37 drives the control plate 35 and the control limit member 31 to reciprocate along the slot hole 1 21 and the slot hole 22. When the limit rod 37 pushes the control limit member 31 to move outward along the slot hole 22, the control component 20 is in an outwardly expanded state, the contact area between the fixed component 2 and the ground is increased, and the stability of the fixed component 2 is increased. When the limit rod 37 pushes the control limit member 31 to move inward along the slot hole 22, the control component 20 is in an inwardly retracted state.

[0056] Then adjust the position of the regulating component 20 according to actual needs;

[0057] Then, when the fixing component 2 is needed to fix the pull wire, the pushing rod 42 on the group of regulating components 20 closest to the pull wire is removed from the lower pressure plate 40, and then the fixing hole 41 on the fixing plate 29 at this location is overlapped with the fixing hole three 43 on the ring member 30, and the bolts pass through the fixing hole 41 and the fixing hole three 43 to achieve the fixation of the fixing plate 29. The regulating component 20 at this location is set as the first regulating component 20, and then the fixing plates 29 on the remaining regulating components 20 are inserted into the soil to achieve the fixation of the fixing component 2, and the pushing rod 42 is fixed to the bottom wall of the lower pressure plate 40 by bolts. When the fixing plate 29 moves down along the slot four 32 and is inserted into the soil, it can drive the lower pressure plate 40 to move down, and the lower pressure plate 40 drives The push rod 42 moves downward to the upper end of the pressure rod 38. As it continues to move, the push rod 42 squeezes the pressure rod 38, and the pressure rod 38 drives the regulating plate 35 and the limit rod 37 to enter the slot three 33. The spring 36 is compressed, and the sleeve 39 is separated from the limit slot 28 and arranged in the slot 21. The fixing plate 29 is inserted into the soil to fix the fixing component 2, and the fixing hole 41 on the fixing plate 29 is overlapped with the fixing hole three 43 on the annular member 30. The bolt passes through the fixing hole 41 and the fixing hole three 43 to fix the fixing plate 29. Then, the pull wire passes through the through hole 17 on the first regulating component 20 and is wound and fixed on the winding roller 26 to fix the pull wire.

[0058] During use, if the pull wire needs to be tightened, the gear 25 rotates to drive the regulating assembly 20 to move outward, and the through hole 17 on the regulating assembly 20 moves outward to squeeze the pull wire.
