Description

Technical Field

[0001] The present invention relates to the technical field of bridge construction protection, and in particular to an intelligent protection device for road and bridge construction. Background Art

[0002] Common road bridges in cities include viaducts. During the installation of drainage pipes and traffic lights on the bottom surface of the viaduct, it is generally necessary to use an external overhead lift to lift the workers. Then the workers drill installation holes or wiring troughs and pipe troughs at the installation locations on the bottom surface of the viaduct. During the drilling process on the bottom surface of the bridge, a large amount of gravel will fall from a high altitude. Gravel falling from a high altitude can easily injure construction workers on the ground. Moreover, gravel falling from a high altitude onto the road surface will spread and break around under the impact of its own gravity, resulting in a large amount of stone remaining on the road surface. These stones also require cleaning personnel to clean the road surface, which makes the construction process of the viaduct unsafe and requires a lot of manpower. In view of this, it is necessary to design a protective device that is convenient for collecting gravel for bridge construction to ensure the safety and efficiency of bridge construction. Summary of the Invention

[0003] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide an intelligent protective device for road and bridge construction, which uses external vacuum equipment to adsorb and fix the suction cup on the bottom surface of the viaduct, so that the support column one and the support column two are fixed on the bottom surface of the viaduct, so that the multiple position adjustment tensioning mechanisms will initially tension and unfold the receiving cloth under the viaduct to be constructed. At this time, the receiving cloth is convenient for receiving gravel falling from a height, preventing the gravel from falling directly from a height to the ground. When a large amount of gravel is collected on the receiving cloth, the motor is turned on to rotate the screw, and the sleeve two on the screw moves along the screw toward the direction of the motor, so that the transmission rod is close to one end of the connecting shaft and rotates in the direction of the screw with the corresponding position connecting seat as the axis, so that one end of the receiving cloth rotates downward and the other end rotates upward, achieving the effect of tilting the receiving cloth (refer to the instruction manual Figure 1 and Figure 3 As shown in the figure), at this time, it is only necessary to manually shake the receiving cloth to facilitate the gravel to fall from the discharge hole on the receiving cloth into the aggregate bag. The aggregate bag will drop the gravel to the predetermined position on the ground to realize the directional transportation of the gravel of the house. By fixing the side baffles on the top edge of the receiving cloth, a traction rope is fixed on the top of the side baffles. In the process of the receiving cloth tilting toward one end of the aggregate bag, the screws at the bottom of the two support columns synchronously drive the winding wheel to rotate, and the winding wheel rotates to reel in the tensioning rope. The tensioning rope is away from the winding wheel. The two corner positions of the traction rope are pulled, so that the side baffles near the inclined end of the receiving cloth are in a straight and tensioned state, preventing the gravel from slipping out of the receiving cloth from the inclined end of the receiving cloth.

When a large amount of gravel and sand accumulates on the collecting cloth, the motor drives the screw to rotate, and the two sleeves engaged with the screw move along the screw, so that the connecting shaft on the transmission rod 2 moves with the collecting cloth, so that one end of the collecting cloth tilts to the lower left, and the other end of the collecting cloth tilts to the lower right, so that the collecting cloth quickly changes to an inclined state, so that the gravel and sand on the collecting cloth flows into the aggregate bag below the discharge hole, which is convenient for collecting gravel and sand during the construction process and ensures the safety of bridge construction.

[0006] Furthermore, connecting seats are fixed at both ends of one side of the connecting plate, and the transmission rod 1 and the transmission rod 2 are respectively rotatably connected to the connecting seats at the corresponding positions, so that the transmission rod 1 and the transmission rod 2 can both rotate on the bottom surface of the connecting plate, meeting the requirement of the connecting shaft to move the cloth.

[0007] Furthermore, the inner side wall of the sleeve 2 is provided with an internal thread which is screwed together with the screw, and the sleeve 1 is rotatably connected to the screw. The screw rotates in different directions to move the sleeve 2 along the screw, so that the transmission rod 3 drives the transmission rod 2 to rotate in different directions, thereby adjusting the cloth receiving position to different positions.

[0008] Furthermore, a motor is fixed inside the chassis, and the output end of the motor is fixedly connected to the screw, so that the motor rotates with the screw to realize the operation of the position adjustment tensioning mechanism, and the motor can rotate with the screw at different positions as the screw moves.

[0010] The further feature is that: a side baffle is fixed to the top edge of the receiving cloth, and a traction rope is inserted into the top surface of the side baffle, wherein one end of the two screws is sleeved and fixed with a winding wheel, and a tensioning rope is wrapped and fixed on the outer wall of the winding wheel, and the end of the tensioning rope facing away from the winding wheel is fixedly connected to the traction rope, and a circular through hole is provided at the bottom of the support column one for convenience of the tensioning rope to pass through, and the height of the end of the side baffle close to the discharge hole is higher, which is convenient for preventing gravel and sand from overflowing from the receiving cloth under the traction of the tensioning rope, and the winding wheel is convenient for winding the tensioning rope as the screw rotates, so that the traction rope can tension the side baffle to block the gravel.

[0011] Furthermore, the height of one end of the side baffle is greater than the height of the other end, and the side baffle and the receiving cloth are both made of elastic fabrics. The side baffle and the receiving cloth are elastic fabrics so that they can adapt to changes during the tensioning and stretching process. The higher height of one end of the side baffle is mainly for the convenience of material blocking.

[0012] Furthermore, the vacuum suction cup is connected and fixed with an external vacuum pumping equipment through a pipeline, the length of the support column one is smaller than that of the support column two, and the external vacuum pumping equipment is convenient for sucking the air inside the vacuum suction cup, so that the vacuum suction cup is adsorbed and fixed to the bottom surface of the viaduct, and the height of the support column one is different from that of the support column two, which is mainly convenient for coordinating the installation of the position adjustment tensioning mechanism at the corresponding position, and the two position adjustment tensioning mechanisms arranged relatively along the length direction of the cloth holding are arranged in a central symmetrical manner, so as to achieve the effect of synchronously adjusting the cloth holding.

[0013] Furthermore, connecting blocks are fixed on the tops of the two connecting shafts, and the connecting blocks are fixedly connected to the corresponding corners of the side baffles, so that the connecting blocks on the connecting shafts support the position of the side baffles away from the blanking hole.

[0014] Beneficial effects of the present invention:

[0015] 1. Use external vacuum equipment to fix the suction cup to the bottom surface of the viaduct, so that the support column 1 and the support column 2 are fixed to the bottom surface of the viaduct, so that the multiple position adjustment tensioning mechanism will initially tension the receiving cloth and unfold it under the viaduct to be constructed. At this time, the receiving cloth is convenient for receiving gravel falling from a height to prevent the gravel from falling directly from a height to the ground. When a large amount of gravel is collected on the receiving cloth, turn on the motor to rotate the screw, and the sleeve 2 on the screw moves along the screw toward the direction of the motor, so that the transmission rod is close to one end of the connecting shaft and rotates in the direction of the screw with the corresponding position connecting seat as the axis, so that one end of the receiving cloth rotates downward and the other end rotates upward, achieving the effect of tilting the receiving cloth (refer to the instruction manual) Figure 1 and Figure 3 As shown in the figure), at this time, you only need to manually shake the receiving cloth to make the gravel fall from the discharge hole on the receiving cloth into the aggregate bag. The aggregate bag will drop the gravel to the predetermined position on the ground to achieve directional conveying of gravel.

[0016] 2. A side baffle is fixed on the edge of the top surface of the receiving cloth, and a traction rope is inserted and fixed on the top of the side baffle. In the process of the receiving cloth tilting toward one end of the aggregate bag, the screw at the bottom of the two support columns synchronously drives the winding wheel to rotate, and the winding wheel rotates to reel in the tensioning rope, and the tensioning rope is pulled away from the winding wheel at one end to pull the two corner positions of the traction rope, so that the side baffle near the inclined end of the receiving cloth is in a straight and tensioned state to prevent the gravel from slipping out of the receiving cloth from the inclined end of the receiving cloth. A camera is installed on one side of one of the support columns one and one of the support columns two near the receiving cloth, so that the camera can monitor the amount of gravel collected on the receiving cloth in real time, and the camera is electrically connected to the external controller. When the camera detects that a large amount of gravel has accumulated on the receiving cloth, the external controller controls the motor drive to operate the position adjustment tensioning mechanism, and then adjusts the position of the receiving cloth to facilitate the transportation of the gravel into the aggregate bag, thereby realizing intelligent cleaning of the gravel on the receiving cloth;

[0017] 3. By rotating multiple screws simultaneously, multiple sleeves 2 can drive the transmission rod 2 at the corresponding position to rotate synchronously, thereby realizing that the two connecting shafts at one end of the receiving cloth drive the receiving cloth to move downward, and the two connecting shafts at the other end of the receiving cloth drive the receiving cloth to move upward synchronously, thereby realizing that the receiving cloth is moved simultaneously from both ends of the receiving cloth, which is convenient for the receiving cloth to be quickly adjusted to an inclined state. When the receiving cloth is in a horizontal state, the position of the two ends of the inclined cloth is adjusted at the same time. The tensioning mechanism is adjusted to make the two ends of the receiving cloth deflect toward the middle position, so that the middle area of the receiving cloth is in a relaxed drooping state, so that the gravel received by the receiving cloth will not fall from the receiving cloth when grooving. In addition, the installation positions of multiple support columns 1 and support columns 2 can be flexibly adjusted as needed, that is, the distance between adjacent support columns 1 and support columns 2 is reduced, so that the middle part of the receiving cloth is bent along its length direction, so as to realize long-distance gravel storage.

The multiple position adjustment tensioning mechanisms 400 are fixed below the construction area through the support column 100 and the support column 2 200 in conjunction with the vacuum suction cup 300. The multiple position adjustment tensioning mechanisms 400 cooperate to open the collecting cloth 600 to facilitate the collection of gravel and sand dropped during construction. When a large amount of gravel and sand accumulates on the collecting cloth 600, the motor drives the screw 450 to rotate, and The screw 450 screws together the two sleeves 441 and moves along the screw 450, so that the connecting shaft 431 on the transmission rod 430 moves with the receiving cloth 600, so that one end of the receiving cloth 600 tilts to the lower left, and the other end of the receiving cloth 600 tilts to the lower right, so that the receiving cloth 600 is quickly transformed into an inclined state, which facilitates the flow of crushed stone and gravel on the receiving cloth 600 into the aggregate bag 700 below the discharge hole 620, so as to facilitate the collection of the accompanying sand and gravel during the construction process, thereby ensuring the safety of bridge construction.

[0029] Both ends of one side of the connecting plate 410 are fixed with connecting seats 411, and the transmission rod 1 420 and the transmission rod 2 430 are respectively rotatably connected to the corresponding connection seats 411, so that the transmission rod 1 420 and the transmission rod 2 430 can both rotate on the bottom surface of the connecting plate 410, meeting the need of the connecting shaft 431 to move the cloth 600; the inner side wall of the sleeve 2 441 is provided with an internal thread that is screwed together with the screw 450, and the sleeve 1 421 is rotatably connected to the screw 450. The screw 450 rotates in different directions to move the sleeve 2 441 along the screw 450, so that the transmission rod 3 440 drives the transmission rod 2 430 to rotate in different directions, so as to adjust the cloth 600 to different positions; a motor is fixed inside the chassis 500, and the output end of the motor is fixedly connected to the screw 450, so that the motor drives the screw 450 to rotate to realize the operation of the position adjustment tensioning mechanism 400, and the motor can rotate with the screw 450 at different positions as the screw 450 moves.

[0030] One end of the receiving cloth 600 is provided with two discharge holes 620, which are connected and fixed to the aggregate bag 700. The top opening diameter of the aggregate bag 700 is larger than the bottom opening diameter thereof. The bottom end of the aggregate bag 700 is detachably tied with a sealing rope. The discharge holes 620 facilitate the transportation of gravel from the receiving cloth 600 to the aggregate bag 700. The upper end of the aggregate bag 700 is large in size for accommodating a large amount of gravel, and the lower end of the aggregate bag 700 is small in size for accommodating the gravel together. A side stopper 610 is fixed to the top edge of the receiving cloth 600, and a traction rope 610 is inserted through the top surface of the side stopper 610. 1, wherein one end of the two screw rods 450 is sleeved and fixed with a winding wheel 451, and the outer wall of the winding wheel 451 is wound and fixed with a tensioning rope 4511, and the end of the tensioning rope 4511 away from the winding wheel 451 is fixedly connected to the traction rope 611, and the bottom of the support column 100 is provided with a circular through hole for the tensioning rope 4511 to pass through. The height of the end of the side guard cloth 610 near the discharge hole 620 is higher, which is convenient for preventing gravel and sand from overflowing from the receiving cloth 600 under the traction of the tensioning rope 4511. The winding wheel 451 is convenient for winding the tensioning rope 4511 as the screw rod 450 rotates, so that the traction rope 611 can tighten the side guard cloth 610 to block the gravel.

[0031] The height of one end of the side baffle 610 is greater than the height of the other end thereof. Both the side baffle 610 and the receiving cloth 600 are made of elastic fabrics. The side baffle 610 and the receiving cloth 600 are made of elastic fabrics so that they can adapt to changes during the tensioning and stretching process. The height of one end of the side baffle 610 is higher mainly for the purpose of blocking the material. The vacuum suction cup 300 is connected and fixed to the external vacuum pumping equipment through a pipeline. The length of the support column 100 is less than the length of the support column 200. The external vacuum pumping equipment is convenient for sucking the air inside the vacuum suction cup 300, so that the vacuum suction cup 300 is adsorbed and fixed to the bottom surface of the viaduct. The heights of support column 1 100 and support column 2 200 are different, mainly to facilitate the installation of the position adjustment tensioning mechanism 400 at the corresponding position, and the two position adjustment tensioning mechanisms 400 arranged relatively along the length direction of the receiving cloth 600 are arranged in a central symmetrical manner to achieve the effect of synchronously adjusting the receiving cloth 600; wherein, the tops of the two connecting shafts 431 are fixed with connecting blocks 4311, and the connecting blocks 4311 are fixedly connected to the corresponding corners of the side cloth 610, so that the connecting blocks 4311 on the connecting shaft 431 support the position of the side cloth 610 away from the blanking hole 620.

[0032] Working principle: When in use, the worker stands on the platform of the lifting vehicle and carries the protective device to the position on the bottom surface of the viaduct where the grooves or holes are to be cut or punched, and then the vacuum suction cups 300 on the top surfaces of the two support columns 100 and the two support columns 200 are pressed against the bottom surface of the viaduct, and at the same time, the external vacuum equipment is operated to suck air into the vacuum suction cups 300, so that the vacuum suction cups 300 adsorb and fix multiple support columns 1 100 and support columns 2 200 on the bottom surface of the viaduct, and the two adjacent support columns 1 100 and the two adjacent support columns 2 200 cooperate to stretch and spread the receiving cloth 600 under the area to be constructed, wherein the receiving cloth 600 can catch the gravel that falls during the construction process. When a large amount of gravel falls on the surface of the receiving cloth 600, the sleeve is opened. The motor in the chassis 500 at one end of the tube 1 421 drives the screw 450 to rotate, causing the sleeve 2 441 screwed together with the screw 450 to move toward the direction of the motor. During the above movement process, the transmission rod 1 420 rotates on the corresponding position connection seat 411 toward the direction of the motor, causing the screw 450 to gradually tilt. The transmission rod 3 440 on the sleeve 2 441 drives the transmission rod 2 430 to rotate in the direction close to the screw 450 with the corresponding position connection seat 411 as the axis. At this time, the connecting shaft 431 at the end of the transmission rod 2 430 synchronously drives the corresponding position corner of the receiving cloth 600 to rotate, thereby realizing the position adjustment of the bottom ends of the two support columns 1 100. The tensioning mechanism 400 moves the receiving cloth 600 to the lower left, and the bottom ends of the two support columns 2 200 The position-adjusting tensioning mechanism 400 drives the receiving cloth 600 to rotate to the upper right, so that the receiving cloth 600 is in an inclined and tensioned state. While the receiving cloth 600 is rotating and tilting, the screw 450 drives the winding wheel 451 to rotate and rewind the tensioning rope 4511. One end of the tensioning rope 4511 away from the winding wheel 451 pulls the two corner positions of the traction rope 611, so that the side baffle 610 near the inclined end of the receiving cloth 600 is in a straight and tensioned state, preventing the gravel from slipping out of the inclined end of the receiving cloth 600. At this time, the operator shakes the receiving cloth 600 to make the gravel and sand fall into the collecting bag 700 from the discharge hole 620 on the receiving cloth 600. The length of the collecting bag 700 can be connected to a suitable length as needed. When the distance between the viaduct and the ground is large, a longer aggregate bag 700 can be used. Finally, the ground personnel open the sealing rope on the aggregate bag 700 to facilitate the discharge of crushed stone and gravel out of the aggregate bag 700. As needed, a camera can be installed on one of the support columns 100 and the support column 2 200 (the two are arranged diagonally to facilitate all-round recording of the upper surface of the receiving cloth 600) near the side of the receiving cloth 600. The camera is arranged toward the receiving cloth 600 and is electrically connected to an external controller. When the camera records that a large amount of crushed stone has accumulated on the surface of the receiving cloth 600, the controller controls the motor to operate the position adjustment tensioning mechanism, thereby adjusting the position of the receiving cloth 600 so that it is tilted toward the direction of the aggregate bag 700.It is convenient to collect the gravel into the aggregate bag 700 for temporary storage.
