Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor are within the protection scope of the utility model.

[0030] As Figure 1 And Figure 2As shown, the embodiment one provides a bridge protection wall formwork carrying trolley, which comprises a frame 1, a handrail 2, wheels 3 and bottom forks 4 for forklifting the formwork. The handrail 2 is installed on the frame 1, and the top end of the handrail 2 extends from the top of the frame 1, which is used for personnel to control the trolley to move forward when carrying the formwork. The bottom forks 4 are arranged on both sides of the bottom of one side of the frame 1, which are used for forklifting the formwork to make it lean on the frame 1. The wheels 3 are arranged on both sides of the bottom of the side of the frame 1 away from the bottom forks 4, which are used for moving the trolley.

[0031] Specific operation steps:

[0032] ① Transport the parts of the trolley to the work site;

[0033] ② Deeply insert the bottom forks 4 of the trolley to the bottom of the protection wall formwork, and kick the bottom of the trolley with the foot to make the protection wall formwork separate from the beam surface;

[0034] ③ Manually move the top of the formwork leaning on the protection wall concrete to make the formwork lean on the frame 1 of the trolley. Thus, the protection wall formwork has been placed on the trolley from the beam surface;

[0035] ④ Two people control the balance and drive the trolley to the next hole beam surface through the trolley handrails 2;

[0036] ⑤ Manually move the top of the formwork leaning on the frame 1 of the trolley to make the formwork lean on the protection wall reinforcement;

[0037] ⑥ Move the bottom forks 4 of the trolley to pull out from the bottom of the protection wall formwork, and complete the carrying of the protection wall formwork.

[0038] In a relatively specific embodiment, the bottom forks 4 are arranged in a wedge-shaped structure at the front end. The trolley frame 1, the handrail 2 and the scissors are welded by stainless steel pipes with a diameter of 3.2 cm and a wall thickness of 1.5 mm. The length of the handrail 2 is 20 cm, the length of the frame 1 is 2.5 m, the height of the frame 1 is 1.3 m, the width of the welded steel plate at the bottom of the frame 1 is 10 cm, the thickness of the welded steel plate is 1 cm, the diameter of the wheel 3 is 40 cm, and the bottom fork 4 is 100 100 angle steel, the bottom edge is polished into a triangular shape, and when the frame 1 is vertically placed, the bottom of the frame 1 is 2 cm away from the ground. In order to ensure the overall stability of the trolley, two scissors are welded inside the frame 1. The bottom forks 4 are fixedly connected with the frame 1, and the bottom end of the handrail 2 is connected with one end of the connecting piece.

[0039] As Figures 3 to 10 shown in embodiment two, the bottom forks 4 are rotatably installed at the bottom of the frame 1 through the connecting piece, and the bottom end of the handrail 2 is connected with one end of the connecting piece. The handrail 2 can control the rotation of the bottom forks 4 through the connecting piece to lift the formwork.

[0040] In use, by pulling the top end of the handrail 2 outward, the handrail 2 drives the end of the bottom fork 4 located at the bottom of the formwork to pry up the formwork, so as to lift the formwork off the ground, thereby facilitating the movement of the formwork to the trolley to realize the loading and supporting of the formwork.

[0041] Further, the connecting piece comprises a connecting block 5 and a connecting shaft 6, the bottom of the frame 1 is provided with a notch 7 matched with the connecting block 5, the connecting block 5 is fixedly arranged on the upper surface of the bottom fork 4, the connecting block 5 is sleeved on the outside of the connecting shaft 6, the two ends of the connecting shaft 6 are rotationally connected with the two side walls of the notch 7, and the connecting block 5 is connected with the handrail 2.

[0042] The bottom fork 4 is rotationally installed on the frame 1 through the cooperation of the connecting block 5 and the connecting shaft 6, and the notch 7 is arranged to prevent the installation of the connecting block 5 from protruding outward from the frame 1, thereby facilitating the loading operation of the formwork.

[0043] Further, the outside of the connecting shaft 6 is provided with a flat surface 8 matched with the width of the connecting block 5, the connecting piece further comprises a screw rod 9, a connecting frame 10 and a labor-saving gear set 11, the inside of the connecting block 5 is provided with a "∅" shaped sleeve groove for sleeving the connecting shaft 6, the screw rod 9 is threadedly connected with the connecting block 5 and penetrates through the connecting block 5, the bottom end of the connecting frame 10 is rotationally connected with the frame 1 with the connecting shaft 6 as the axis, the outside end of the screw rod 9 penetrates through the connecting frame 10 and rotationally cooperates with the connecting frame 10, the labor-saving gear set 11 is installed in the connecting frame 10, and the lowest gear in the labor-saving gear set 11 is fixedly sleeved on the outside end of the screw rod 9, and the bottom end of the handrail 2 rotationally cooperates with the connecting frame 10 and is fixedly connected with the highest gear in the labor-saving gear set 11.

[0044] By rotating the handrail 2 to the left and right directions, the handrail 2 drives the labor-saving gear set 11 to rotate, and the labor-saving gear set 11 drives the screw rod 9 to rotate, at this time, the screw rod 9 can control the bottom fork 4 to insert into or withdraw from the bottom of the formwork.

[0045] In the process of loading the formwork, the trolley is moved to be close to the formwork, at this time, the bottom fork 4 is located outside the bottom of the formwork, then the trolley is adjusted so that the inside end of the bottom fork 4 is directed to the bottom of the formwork, and then the handrail 2 is pulled to one side to drive the bottom fork 4 to insert into the bottom of the formwork.

[0046] Specifically, in the operation process, two workers can simultaneously pull two handrails 2 in opposite directions, and in the process of synchronously inserting the two bottom forks 4 into the bottom of the formwork, since the pulling directions of the two workers on the trolley are opposite, the stability of the formwork during loading can be ensured without displacement of the trolley.

[0047] After the bottom fork 4 is inserted into the formwork, the worker pulls the top end of the handrail 2 away from the surface of the formwork, so that the bottom fork 4 rotates at the bottom of the frame 1 to lift the formwork off the ground.

[0048] When the bottom fork 4 rotates to the maximum angle, as the staff continues to pull the top end of the handrail 2 outward, the top end of the trolley will be turned outward, so that the formwork lifted by the bottom fork 4 can be more easily tilted outward and collapsed on the frame 1, realizing the loading of the formwork.

[0049] Then, the handrail 2 is reset in the inward and outward direction, and the bottom fork 4 returns to the initial state, with its upper surface fully supporting the bottom of the loaded formwork, providing effective support for the formwork to facilitate the transfer of the formwork.

[0050] When the formwork is transferred to the appropriate location, the handrail 2 is turned in the opposite direction, so that the bottom fork 4 is directly extracted from the bottom of the formwork, realizing the lowering operation of the formwork.

[0051] In this embodiment, the connecting shaft 6 cooperates with the screw rod 9 to form a "T" shaped structure, and is arranged through the connecting block 5, so that the connecting block 5 can not only slide in the direction of the screw rod 9, but also be driven to rotate by the screw rod 9 to achieve the purpose of lifting the formwork by the bottom fork 4.

[0052] The labor-saving gear set 11 adopts a labor-saving mode of driving a large gear to rotate by a pinion, realizing the labor-saving effect, and further cooperating with the force arm formed by the handrail 2 in the height direction, which is more convenient for the operation of inserting the bottom fork 4 into the formwork machine to lift the formwork.

[0053] The connecting member further comprises a support plate 12 fixedly arranged at the bottom of the two side surfaces of the connecting frame 10, and the inner side end of the support plate 12 is sleeved on the connecting shaft 6. The support plate 12 rotates the connecting frame 10 to be installed on the frame 1, so that the connecting frame 10 as a whole can be synchronously rotated with the bottom fork 4, and can effectively transmit the force of the handrail 2 to the bottom fork 4, realizing the rotating operation of the bottom fork 4.

[0054] The technical scope of the utility model is not limited to the content in the above description, and those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical thought of the utility model, and these deformations and modifications should all belong to the scope of the utility model.
