Description

Technical Field

[0001] The present invention relates to the technical field of road viaduct bridge anti-collision guardrail construction, in particular to an anti-collision guardrail construction safety operation vehicle. Background Art

[0002] With the rapid development of the transportation infrastructure industry, bridges, as a vital component of transportation routes, play an irreplaceable role. A viaduct, a type of bridge, generally refers to a bridge that spans a road in an urban area or a highway bridge that spans land in the wild. Viaducts are supported by high-supported towers or pillars. Anti-collision guardrails are a crucial component of viaducts, but traditional guardrail construction trolleys have drawbacks such as bulk, low mobility, limited rotation angles, and non-reusability, making them difficult to meet today's rapidly evolving construction schedules and safety requirements.

[0003] Chinese patent publication number CN111794097A discloses a vehicle for safely constructing elevated bridge anti-collision guardrails. The vehicle comprises a driving platform for traveling on a bridge surface, a base frame hinged to the upper end of the driving platform, a gangway mounted on the base frame, a connecting frame mounted on the gangway, a hanging basket mounted on the connecting frame for people to stand on, and a first hydraulic cylinder mounted on the driving platform. The gangway is detachably connected to the upper end of the base frame; the connecting frame is detachably connected to an end of the aisle away from the base frame; the hanging basket is detachably connected to an end of the connecting frame away from the aisle; the first hydraulic cylinder is hinged at one end to the driving platform and at the other end to the base frame, and is connected to the hydraulic system of the work vehicle, driving the base frame to rotate. The driving platform and the hanging basket can be positioned on opposite sides of the anti-collision guardrail. This application improves the safety of workers during elevated bridge anti-collision guardrail construction.

[0004] However, the above-mentioned patent proposes a construction vehicle for installing an overpass anti-collision guardrail, in which the aisle, the connecting frame and the hanging basket are detachably connected during use, and the chassis is rotated only by the first hydraulic cylinder as the main driving source, thereby lowering the aisle, the connecting frame and the hanging basket, so that the hanging basket is located on the outside of the overpass anti-collision guardrail, and the construction workers enter the hanging basket through the aisle and the connecting frame. This method is not convenient for operation to adjust the direction and height between the hanging basket and the overpass in time according to needs, and it takes too much time to install and disassemble, which easily affects the construction efficiency.

[0050] like Figure 1-Figure 3 as well as Figure 6-Figure 7 As shown, in order to fix the connecting bracket 7 and the walking bracket 5 together, the connecting bracket 7 and the walking bracket 5 are connected together through a first clamping mechanism. The first clamping mechanism includes a support cover 9 fixedly mounted on the upper surface of the upper turntable 8, and an electric telescopic rod 901 is fixedly mounted on the upper surface of the support cover 9. One end of the electric telescopic rod 901 extends into the support cover 9 and is fixedly connected to a support block 902 distributed in a cross shape. The inner wall of the support cover 9 is provided with a slide groove 903 distributed in a circular array. The surface of the support block 902 is slidably engaged with the inner wall of the slide groove 903. The support cover 9 is used to support the electric telescopic rod 901, and the slide groove 903 opened on its inner wall facilitates the limitation of the movement of the support block 902. The extension of one end of the electric telescopic rod 901 drives the support block 902 to move downward along the inner wall of the slide groove 903.

[0051] like Figure 4 as well as Figure 7-Figure 9 As shown, in order to facilitate the connection between the walking bracket 5 and the connecting bracket 7, connecting rods 904 are distributed in a rectangular array on the lower surface of the support block 902, and a through-hole 905 is provided on the surface of the upper turntable 8. The lower end of the connecting rod 904 is slidably connected to the inner wall of the through-hole 905 and is fixedly connected to a positioning shell 906. A slot 907 is provided on the upper surface of the walking bracket 5, and the surface of the positioning shell 906 is slidably engaged with the inner wall of the slot 907. The movement of the support block 902 drives the connecting rod 904 to move, and the downward movement of the connecting rod 904 drives the positioning shell 906 to extend from the through-hole 905 and plug into the slot 907.

[0052] like Figure 9-10As shown, in order to clamp the positioning housing 906 with the card slot 907, a support plate 908 is fixedly installed on the inner wall of the positioning housing 906, a servo motor 909 is fixedly installed on the upper surface of the support plate 908, and a rotating plate 910 is installed on the lower surface of the support plate 908 through a bearing. One end of the output shaft of the servo motor 909 passes through the support plate 908 and is fixedly sleeved with the axis of the rotating plate 910. An arc groove 911 is opened on the surface of the rotating plate 910, and a sliding column 912 is slidably clamped on the inner wall of the arc groove 911. The upper end of the sliding column 912 is fixedly connected to a T-shaped plate 913. The surface of the support plate 908 is annular. The surface of the T-shaped plate 913 is slidably engaged with the inner wall of the positioning groove 914, and the surface of the positioning shell 906 is distributed in a ring array with grooves 915. The T-shaped plate 913 passes through the groove 915 and is engaged with the inner wall of the card slot 907. The rotation of the output shaft of the servo motor 909 drives the rotating plate 910 to rotate. The rotation of the rotating plate 910 drives the sliding column 912 to move along the inner wall of the arc groove 911, and then drives the T-shaped plate 913 to move out of the positioning shell 906 along the inner wall of the positioning groove 914 and the groove 915, so that the T-shaped plate 913 is engaged with the inner wall of the card slot 907.

[0053] By setting up a first clamping mechanism, it is convenient to quickly disassemble and assemble the connecting bracket 7 and the traveling bracket 5 without the aid of tools, thereby improving construction efficiency. The positioning is performed by plugging the positioning shell 906 into the card slot 907, which facilitates driving the T-plate 913 to engage with the inner wall of the card slot 907, thereby further stabilizing the connection between the connecting bracket 7 and the traveling bracket 5. Each time the rotating mechanism drives the connecting bracket 7 to rotate 90 degrees, the connecting bracket 7 is clamped by the guide mechanism so that the positioning shells 906 at different positions on the upper turntable 8 can be aligned with the card slot 907, thereby effectively fixing the connecting bracket 7 and the traveling bracket 5 together.

[0054] like Figure 11 and Figure 15As shown, in order to fix the connecting bracket 7 and the hanging basket 11 together, the second clamping mechanism is used to connect the connecting bracket 7 and the hanging basket 11 together, and the second clamping mechanism includes a connecting disc 10 fixedly installed on the upper surface of the lower turntable 81, and the upper surface of the connecting disc 10 is fixedly connected to the lower end of the connecting bracket 7. The upper limit plate 107 and the lower limit plate 108 are respectively provided on both sides of the outer surface of the connecting disc 10 and the lower turntable 81. The upper limit plate 107 and the lower limit plate 108 are respectively provided with symmetrically distributed threaded rods 109 on the opposite sides through bearings. The inner walls of the upper limit plate 107 and the lower limit plate 108 are fixedly installed with a rotating motor 110, and the output shaft of the rotating motor 110 One end is fixedly connected to one end of the threaded rod 109, and threaded holes 111 are provided on the surfaces of the walking bracket 5 and the hanging basket 11. The surface of the threaded rod 109 is threadedly connected to the inner wall of the threaded hole 111, and a hydraulic clamp 112 is provided at the other end of the threaded rod 109. After the threaded rod 109 on the lower turntable 81 is aligned with the threaded hole 111 on the hanging basket 11, the threaded rod 109 is driven to rotate by rotating the output shaft of the rotating motor 110, and with the cooperation of the self-driving slide rail 6, the threaded rod 109 is inserted into the threaded hole 111, and the hydraulic clamp 112 is driven to pass through the threaded hole 111, and then the hydraulic clamp 112 is opened to facilitate the connection between the connecting bracket 7 and the hanging basket 11.

[0055] like Figure 12-14 As shown, in order to facilitate the alignment of the threaded rod 109 on the connecting disk 10 with the threaded hole 111 on the walking bracket 5, a driving motor 101 is fixedly installed on the inner wall of the connecting disk 10, and a cavity 102 is opened on the inner wall of the connecting disk 10. A bidirectional screw 103 is installed on the inner wall of the cavity 102 through a bearing. One end of the output shaft of the driving motor 101 is fixedly sleeved with one end of the bidirectional screw 103. Two threaded blocks 104 are threadedly sleeved on the surface of the bidirectional screw 103. The surface of the threaded block 104 is slidably engaged with the inner wall of the cavity 102. The outer surface of the threaded block 104 is hinged with hinged rods 105 on both sides. The hinged rod 105 is away from one end of the threaded block 104. The end is hinged with a slide 106, and the surface of the slide 106 is slidably engaged with the inner wall of the cavity 102. The end of the slide 106 extending out of the cavity 102 is fixedly connected to the side of the upper limit plate 107 close to the connecting disk 10, and the rotation of the output shaft of the driving motor 101 drives the bidirectional screw 103 to rotate. The rotation of the bidirectional screw 103 drives the two threaded blocks 104 to move relative to the bidirectional screw 103 along the inner wall of the cavity 102. The movement of the threaded block 104 drives the hinged rod 105 to deflect, thereby driving the slide 106 to move along the inner wall of the cavity 102, and the movement of the slide 106 drives the upper limit plate 107 connected to it to move.

[0056] By setting up a second clamping mechanism, it is convenient to quickly disassemble and assemble the connecting bracket 7 and the hanging basket 11 without the aid of tools, thereby improving construction efficiency. The threaded rod 109 on the lower turntable 81 is connected to the threaded hole 111 on the hanging basket 11 under the cooperation of the guiding mechanism and the threaded connection between the threaded rod 109 and the threaded hole 111, and the hydraulic clamp 112 is opened after passing through the threaded hole 111, thereby further stabilizing the connection between the connecting bracket 7 and the hanging basket 11. At the same time, when the guiding mechanism drives the connecting bracket 7 to move upward, the threaded rod 109 on the connecting plate 10 is aligned with the threaded hole 111 on the walking bracket 5, so as to facilitate the storage of the hanging basket 11 into the walking bracket 5.

[0057] like Figure 6-Figure 8 As shown, in order to facilitate the adjustment of the angle of the hanging basket 11, the rotating mechanism is used to drive the connecting bracket 7 to rotate, thereby driving the hanging basket 11 to achieve angle rotation. The rotating mechanism includes an upper turntable 8 and a lower turntable 81 respectively arranged at both ends of the connecting bracket 7. The lower surface of the upper turntable 8 is fixedly connected to the upper end of the connecting bracket 7, and a rotating motor 82 is installed on the upper surface of the upper turntable 8 through a bearing. One end of the output shaft of the rotating motor 82 is fixedly sleeved with the axis of the upper turntable 8. The rotating motor 82 is located in the support cover 9 and the rotating motor 82 is below the support block 902 to avoid the downward movement of the support block 902 and the movement interference of the rotating motor 82. The rotation of the output shaft of the rotating motor 82 drives the upper turntable 8 connected thereto to rotate, the rotation of the upper turntable 8 drives the connecting bracket 7 to rotate, the rotation of the connecting bracket 7 drives the lower turntable 81 to rotate, and the rotation of the lower turntable 81 drives the hanging basket 11 to rotate through the second clamping mechanism.

[0058] like Figure 1-Figure 5 As shown, in order to facilitate the up and down movement of the connecting bracket 7, the guide mechanism is used to drive the connecting bracket 7 to move up and down, thereby realizing height adjustment of the hanging basket 11, and the guide mechanism includes a self-driving slide rail 6 distributed in a rectangular array on the traveling bracket 5, and the inner side wall of the connecting bracket 7 is connected to the slider on the self-driving slide rail 6 through a hydraulic chuck 61, and a receiving groove 62 is provided on the surface of the traveling bracket 5 close to the self-driving slide rail 6, and a pushing cylinder 63 is fixedly installed on the inner wall of the traveling bracket 5 close to the receiving groove 62, and one end of the piston rod of the pushing cylinder 63 extends into the receiving groove 62 and is fixedly connected to the side of the self-driving slide rail 6 close to the receiving groove 62, and the extension of the piston rod of the pushing cylinder 63 drives the self-driving slide rail 6 to move out of the receiving groove 62 and makes the slider on the self-driving slide rail 6 contact with the hydraulic chuck 61 on the connecting bracket 7, so that the hydraulic chuck 61 clamps it, so that the movement of the slider on the self-driving slide rail 6 drives the connecting bracket 7 to move.

[0059] Working principle: When in use, first insert one end of the connecting bracket 7 with the lower turntable 81 into the walking bracket 5 so that it contacts the hanging basket 11, then push the piston rod of the cylinder 63 to extend and drive the self-driving slide rail 6 to move out of the storage groove 62, so that the slider on the self-driving slide rail 6 is clamped by the hydraulic chuck 61 on the connecting bracket 7, and then fix the connecting bracket 7 and the hanging basket 11 together, so that the threaded rod 109 on the lower turntable 81 is aligned with the threaded hole 111 on the hanging basket 11, and start the rotating motor 110 in the lower turntable 81 and the self-driving slide rail 6, so that the threaded rod 109 drives the hydraulic clamping claw 112 to insert into the threaded hole 111, and when the hydraulic clamping claw 112 passes through the threaded hole 111, the hydraulic clamping claw 112 opens, thereby fixing the connecting bracket 7 and the hanging basket 11 together;

[0060] In order to prevent the hanging basket 11 from colliding with the viaduct during the downward movement, a steel wire rope is used to hang the upper end of the connecting bracket 7, so that the hydraulic clamp 112 releases the slider on the self-driving slide rail 6, and the piston rod of the cylinder 63 is pushed to retract and the self-driving slide rail 6 is retracted into the receiving groove 62. Then the rotating motor 82 is started, and the rotation of the output shaft of the rotating motor 82 drives the upper turntable 8 connected thereto to rotate, and the rotation of the upper turntable 8 drives the connecting bracket 7 to rotate, and the rotation of the connecting bracket 7 drives the lower turntable 81 to rotate, and the rotation of the lower turntable 81 drives the hanging basket 11 to rotate, so that the hanging basket 11 is parallel to the viaduct, and then the piston rod of the cylinder 63 is pushed to extend to drive the slider on the self-driving slide rail 6 to be clamped by the hydraulic clamp 112 on the other inner wall of the connecting bracket 7;

[0061] Then, under the action of the self-driving slide rail 6, the connecting bracket 7 is driven to move downward, and the downward movement of the connecting bracket 7 drives the hanging basket 11 to move downward. When it moves down to a certain position, the self-driving slide rail 6 returns to the storage groove 62 again under the action of the pushing cylinder 63, and the output shaft of the rotating motor 82 rotates in the opposite direction to drive the hanging basket 11 and the viaduct to be in a vertical state. At the same time, the upper turntable 8 contacts the upper surface of the walking bracket 5 and the positioning shell 906 is aligned with the card slot 907. When the end of the electric telescopic rod 901 on the support cover 9 connected to the support block 902 is extended, it drives the support block 902 to move downward along the inner wall of the slide groove 903. As the support block 902 moves downward, the connecting rod 904 moves downward, so that the connecting rod 904 drives the positioning shell 906 to move out of the through hole 905 and insert into the card slot 907, and then the servo motor 909 is started. The rotation of the output shaft of the servo motor 909 drives the rotating plate 910 to rotate. The rotation of the rotating plate 910 drives the sliding column 912 to move along the inner wall of the arc groove 911, and then drives the T-shaped plate 913 to move out of the positioning shell 906 along the inner wall of the positioning groove 914 and the groove 915, so that the T-shaped plate 913 is engaged with the inner wall of the card slot 907, thereby fixing the connecting bracket 7 and the walking bracket 5 together.
