Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, and in particular relates to a new type of bridge anti-collision guardrail casting trolley. Background Art

[0002] In recent years, as bridges continue to develop in the direction of large span, light weight, high strength and integrity, various high pier bridges continue to emerge. Safety issues during construction are an important challenge currently facing engineering construction, especially the safety management of high-altitude operations in highway bridge construction. In existing bridge engineering operations, after the bridge beams and slabs are cast, it is necessary to cast and construct anti-collision guardrails on both sides of the top of the bridge beams and slabs. As an auxiliary structure of the bridge, the bridge anti-collision guardrail has been widely used in highways and plays a vital role in the safety protection of various vehicles traveling on the road. At the same time, it is also extremely important to pay attention to safety management during the construction of the anti-collision guardrail. Since the anti-collision guardrail is located on both sides of the top of the bridge and is about 1.3m high, the construction workers cannot operate conveniently when pouring concrete and vibrating concrete. The overall operation process has the problems of high difficulty and high safety risks.

[0003] The utility model patent with publication number CN 213925895 U discloses a new type of bridge anti-collision guardrail casting trolley. This technical solution, through the design of the trolley body, the vibrating work platform, the concrete chute and the guardrail assembly, can facilitate the technicians to stand on the top of the vibrating work platform to cast and vibrate concrete during concrete casting and concrete vibrating, and can also protect the technicians during the operation, thereby effectively reducing the difficulty of concrete casting and concrete vibrating, and reducing the safety risks during the operation. However, the concrete chute in the above technical solution is a fixed design, and its height and length cannot be adjusted, thereby reducing the accuracy and stability of the concrete chute when unloading, and the material is prone to spillage. Therefore, it is necessary to design a new type of bridge anti-collision guardrail casting trolley with adjustable height and length of the concrete chute. Utility Model Content

[0044] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0045] Example 1

[0046] like Figures 1 to 7 As shown, the embodiment of the utility model provides a new bridge anti-collision guardrail casting trolley, comprising:

[0047] Base 1;

[0048] Two support plates 2 are respectively welded vertically and symmetrically on the left and right sides of the top of the base 1;

[0049] The working platform 3 is welded on the top of the two support plates 2; through the design of the working platform 3, it is convenient for construction workers to stand on the top of the working platform 3 to pour and vibrate concrete when pouring and vibrating concrete.

[0050] Two guardrail frames 4 are symmetrically arranged on the left and right sides of the top of the working platform 3 respectively; in the present embodiment, the guardrail frame 4 is preferably a "U"-shaped guardrail frame with openings on the top and front side, and a guardrail door 17 is arranged on the front side of the guardrail frame 4. The guardrail door 17 can be locked with the guardrail frame 4 by an existing latch to avoid the risk of the guardrail door 17 opening automatically during the construction process, which may cause the construction workers to fall. The design of the surrounding guardrail frame 4 can form surrounding protection for the construction workers to avoid the construction workers from falling from the back, left or right side of the working platform 3 during the pouring and vibration process, thereby improving the safety of the construction.

[0051] The height adjustment component is arranged at the middle of the top of the working platform 3; the discharging component is arranged at the top of the height adjustment component.

[0052] The height adjustment kit includes:

[0053] A drive assembly is arranged in the middle of the top of the working platform 3;

[0054] The two adjusting rods 8 are specifically arranged to rotate crosswise through a pin, and the bottoms of the two adjusting rods 8 are hingedly arranged on the top of the driving assembly;

[0055] The sliding assembly is hingedly arranged on the top of the two adjusting rods 8 and connected to the bottom of the discharging assembly.

[0056] The articulation methods mentioned above all adopt existing conventional articulation methods, such as pins or hinges.

[0057] The drive components include:

[0058] Two mounting plates 12 are vertically symmetrically welded and arranged at the middle of the top of the working platform 3;

[0059] The bidirectional screw rod 9 is transversely arranged between the two mounting plates 12, and both ends of the bidirectional screw rod 9 respectively penetrate the adjacent mounting plates 12 and are rotatably connected with the adjacent mounting plates 12. In this embodiment, both ends of the bidirectional screw rod 9 are rotatably connected with the fixing plate 12 through bearings.

[0060] The motor 10 is fixedly installed on the top of the working platform 3 by bolts, and the output shaft of the motor 10 is fixedly connected to one end of the bidirectional screw 9. The motor 10 can be a conventional servo motor. The servo motor drives the bidirectional screw to rotate forward or reversely through forward and reverse rotation, thereby driving the two threaded adjustment blocks 11 to move in opposite directions.

[0061] Two threaded adjustment blocks 11 are movably mounted on the bidirectional screw 9, and the tops of the threaded adjustment blocks 11 are respectively hinged to the bottoms of the corresponding adjustment rods 8. In this embodiment, the two threaded adjustment blocks 11 are respectively mounted on different threaded portions on the bidirectional screw 9, so that when the motor 10 drives the bidirectional screw 9 to rotate forward or reverse, the two threaded adjustment blocks 11 can move closer to or farther from each other along the bidirectional screw 9, thereby driving the discharge hopper 5 to move up or down, and thus adjusting the height of the discharge hopper 5.

[0062] A limit slot 13 is provided in the middle of the top of the working platform 3, and the bottoms of the two threaded adjustment blocks 11 are respectively slidably connected to the limit slots 13. Through the design of the limit slots 13, when the bidirectional screw rod 9 is driven by the motor 10 to rotate, the two threaded adjustment blocks 11 will not rotate with the bidirectional screw rod 9, but will move closer to or away from each other along the bidirectional screw rod 11.

[0063] The sliding component contains:

[0064] Two limit plates 20 are symmetrically welded and arranged at the bottom of the discharge assembly;

[0065] The sliding rod 21 is transversely arranged between the two limiting plates 20, and the two ends are respectively welded to the adjacent limiting plates 20;

[0066] The two sliding blocks 22 are slidably disposed on the sliding rod 21 , and the bottoms of the two sliding blocks 22 are respectively hinged to the tops of the corresponding adjusting rods 8 .

[0067] In this embodiment, the height adjustment method of the discharge hopper 5 is specifically as follows:

[0068] Start the motor 10 to drive the bidirectional screw 9 to rotate, and the two threaded adjustment blocks 11 can move closer to or farther away from each other along the bidirectional screw 9, thereby driving the two adjustment rods 8 to make a steering movement closer to or farther away from each other along the hinge point. At this time, the two sliding blocks 22 move closer to or farther away from each other along the sliding rod 21, thereby driving the discharge hopper 5 to move up or down, so that the height of the discharge hopper 5 can be adjusted.

[0069] The discharge assembly includes:

[0070] The discharge hopper 5 is welded on the top of the two limit plates 20;

[0071] The auxiliary bucket 6 is slidably arranged at the front end of the discharge hopper 5 through a connecting component; in the specific design of this embodiment, the bottom of the auxiliary bucket 6 is in contact with the inner side of the bottom of the discharge hopper 5, and such a design can improve the connection stability between the discharge hopper 5 and the auxiliary bucket 6. The discharge hopper 5 and the auxiliary bucket 6 are both inclined in design, and such a design can facilitate the concrete poured on the discharge hopper 5 to enter the casting mold of the bridge anti-collision guardrail.

[0072] The hydraulic rod 7 is arranged between the bottom of the discharge hopper 5 and the auxiliary bucket 6. The hydraulic rod 7 in this embodiment adopts the existing hydraulic rod, and does not involve the modification of the hydraulic rod. In the specific implementation process, it can also be replaced with other power mechanisms, such as electric push rods, as long as it can push the auxiliary bucket 6 to move forward or backward along the discharge hopper 5. Specifically, the hydraulic cylinder on the hydraulic rod 7 is connected to the bottom of the discharge hopper 5, and the movable end of the piston rod on the hydraulic rod 7 is connected to the bottom of the auxiliary bucket 6 through the connecting block 16.

[0073] The connection components include:

[0074] Two chutes 15 are symmetrically arranged on the inner wall of the left and right sides of the discharge hopper 5;

[0075] Two sliders 14 are fixedly and symmetrically arranged at the rear side of the left side and the right side of the auxiliary bucket 6, and each slider 14 is slidably connected to the adjacent chute. Through the design of the chute 15 and the slider 14, the auxiliary bucket 6 can be easily moved forward or backward along the discharge hopper 5 under the push of the hydraulic rod 7, so as to adjust the length of the discharge hopper 5.

[0076] A plurality of foot pedals 18 for climbing are arranged at intervals between the front sides of the two support plates 2, and the two ends of each foot pedal 18 are respectively welded to the front side of the adjacent support plate 2. The construction personnel can climb to the top of the working platform 3 through the foot pedals 18, and then enter the guardrail frame 4 by opening the guardrail door 17, and then close the guardrail door 17 and stand on the top of the working platform 3 to pour concrete or vibrate.

[0077] A plurality of universal wheels 19 with locking functions are evenly arranged at the bottom of the base 1. Through the design of the universal wheels 19, the trolley provided in the embodiment of the utility model can be easily moved. After the trolley is moved to the work station, the construction personnel can lock the universal wheels 19 so that the universal wheels 19 cannot move, thereby preventing the working platform 3 from shaking during the pouring and vibrating process.

[0078] Example 2

[0079] This embodiment provides a working method of the new bridge anti-collision guardrail casting trolley of embodiment 1, comprising the following steps:

[0080] First, the construction workers push the entire new bridge anti-collision guardrail casting trolley, so that the new bridge anti-collision guardrail casting trolley moves through the universal wheels 19 at the bottom. After moving to the work station, the universal wheels 19 are locked. Then the construction workers climb to the top of the working platform 3 by stepping on the foot pedal 18, and then stand on the top of the working platform 3. According to the required casting height, the motor 10 is started to drive the bidirectional screw rod 9 to rotate, and the two threaded adjustment blocks 11 can move closer or farther along the bidirectional screw rod 9 to drive the discharge hopper 5 to move up or down, and the height of the discharge hopper 5 can be adjusted. Then, according to the lateral distance to be poured, the hydraulic rod 7 is started to drive the piston rod to move forward or backward, and the auxiliary bucket 6 is pushed forward or backward along the discharge hopper 5 to adjust the length of the discharge hopper 5. After the height and length of the discharge hopper 5 are adjusted, the construction personnel can align the concrete output pipe with the discharge hopper 5. After the concrete is output, it falls on the discharge hopper 5 and the auxiliary discharge hopper 6, and then flows into the guardrail mold along the discharge hopper 5 and the auxiliary discharge hopper 6. At this time, the construction personnel can stand on the top of the working platform 3 and be located in the guardrail frame 4, and then use the vibrating equipment to vibrate the guardrail mold.

[0081] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
