[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please see Figure 1-4 The present invention provides the following technical solution: a steel formwork trolley for irrigation canal engineering, comprising a vehicle body 1, two slide rails 3 provided below the vehicle body 1, multiple pulleys 2 fixedly installed below the vehicle body 1 and inside the two slide rails 3, a storage battery 5 fixedly installed above the vehicle body 1, a tilting adjustment device 4 installed near the center of the vehicle body 1, and a protective buffer device 6 fixedly installed above the vehicle body 1 and outside the storage battery 5.

[0022] Specifically, the tilt adjustment device 4 includes a connecting plate 41, a U-shaped frame 42, a fixed shaft 43, a steel template 44, abutment block 45, a first electric telescopic rod 46, and an adjustment assembly 47. Connecting plates 41 are provided on both sides of the vehicle body 1. A U-shaped frame 42 is fixedly installed on the side of the connecting plate 41 away from the vehicle body 1. A fixed shaft 43 is fixedly installed on the inner side of the U-shaped frame 42. A steel template 44 is installed on the outer side of the fixed shaft 43 and on the inner side of the U-shaped frame 42 via a bearing. A first electric telescopic rod 46 is fixedly installed on both sides of the connecting plate 41 away from the vehicle body 1 and on the upper and lower sides of the U-shaped frame 42. Abutment block 45 is fixedly connected to the side of the first electric telescopic rod 46 near the steel template 44. The vehicle body 1 is connected to the two connecting plates 41 via two adjustment assemblies 47.

[0023] By adopting the above technical solution, workers can adjust the inclination of the steel formwork 44 on both sides when needed by using the cooperation of structures such as the abutment block 45 and the fixed shaft 43, thereby adapting to the diversion channel project with different inclination surfaces.

[0024] Specifically, the pitch adjustment assembly 47 includes a geared motor 471, a moving rod 472, a moving plate 473, and a double-acting screw 474. The geared motor 471 is fixedly installed on the inner side of the vehicle body 1. The double-acting screw 474 is fixedly connected to one side of the output end of the geared motor 471. Two moving plates 473 are threadedly installed on the outer side of the double-acting screw 474 and on the inner side of the vehicle body 1. The moving plates 473 are connected to the connecting plate 41 through the two moving rods 472.

[0025] By adopting the above technical solution, workers can adjust the distance between the two steel templates 44 on both sides when needed by using the combination of structures such as the bidirectional screw 474 and the movable plate 473, thereby better meeting the work needs in different situations.

[0026] Specifically, the side wall of the vehicle body 1 and the outer side of the moving rod 472 are fitted together.

[0027] By adopting the above technical solution, the trolley can limit and guide the movement of the moving rod 472 through the trolley body 1, thereby preventing the moving rod 472 and its structure from deviating and ensuring the normal operation of the work.

[0028] In this embodiment, when a steel formwork trolley is needed for the irrigation canal project, the two slide rails 3 are fixed in the working position. The workers adjust the position of the trolley body 1 and other structures by cooperating with the slide rails 3 and pulleys 2. If the inclination of a certain steel formwork 44 in the tilt adjustment device 4 needs to be adjusted, the two corresponding first electric telescopic rods 46 are activated, thereby driving the two abutment blocks 45 to move. The two first electric telescopic rods 46 drive the two abutment blocks 45 to move towards the steel formwork 44 and away from the steel formwork 44 respectively, thereby pushing the steel formwork 44 to rotate around the fixed axis 43 in the U-shaped frame 42 until the steel formwork... Plate 44 is rotated to the required tilt angle, and then the operator starts the reduction motor 471 in the adjustment assembly 47, which drives the bidirectional lead screw 474. The bidirectional lead screw 474 is threadedly connected to the two moving plates 473, and the moving rods 472 on the two moving plates 473 are slidably connected to the vehicle body 1. Therefore, the bidirectional lead screw 474 drives the two moving plates 473 and their moving rods 472 and connecting plate 41 to move until the two steel templates 44 are moved to the required position for use. The first electric telescopic rod 46 and the reduction motor 471 are electrically connected to the battery 5.

[0029] Example 2

[0030] The difference between this embodiment and embodiment 1 is that the protective buffer device 6 includes an L-shaped frame 61, a damper 62, an elastic rubber frame 63, and a protective plate 66. The L-shaped frame 61 is fixedly installed on the top of the vehicle body 1 and on both sides of the battery 5. The protective plate 66 is provided on the top of the two L-shaped frames 61. Two elastic rubber frames 63 are fixedly connected between the protective plate 66 and the two L-shaped frames 61. Two dampers 62 are fixedly connected between the protective plate 66 and the two L-shaped frames 61 and on the inner side of the two elastic rubber frames 63.

[0031] By adopting the above technical solution, staff can use the combination of protective plate 66 and elastic rubber frame 63 to block and buffer the impact of external rainstorms and hail when needed, thereby reducing the possibility of the trolley being adversely affected by the outside world.

[0032] Specifically, the protective buffer device 6 also includes an L-shaped plate 64 and a second electric telescopic rod 65. The inner sides of both ends of the protective plate 66 are provided with L-shaped plates 64, and the protective plate 66 and the two L-shaped plates 64 are connected by two second electric telescopic rods 65.

[0033] By adopting the above technical solution, staff can expand the protection range when needed by using the L-shaped plate 64 and the second electric telescopic rod 65, thereby better meeting the work needs in different situations.

[0034] In this embodiment, when the trolley encounters heavy rain, hail, or other weather conditions, the operator can activate the two second electric telescopic rods 65 in the protective buffer device 6, thereby moving the two L-shaped plates 64 and adjusting the overall area of ​​the two L-shaped plates 64 and the protective plate 66. The dampers 62 and elastic rubber frames 63 on the two L-shaped frames 61 can buffer the impact encountered by the two L-shaped plates 64 and the protective plate 66, thereby reducing the possibility of the trolley being adversely affected.

[0035] The structure and principle of the damper 62, which consists of a cylinder, piston rod, piston, first pressure plate, second pressure plate, damping shaft, viscous fluid, first hollow screw, second hollow screw, pressure block, spring, first outer hole, first inner hole, second outer hole, second inner hole, pressure-bearing middle part, first pressure-bearing end, second pressure-bearing end, first guide part, second guide part, shaft body, direct flow channel, first head and second head, have been disclosed in the speed-adjustable damper disclosed in Chinese patent application number 202121081254.2. Its working principle is that a uniform speed shaft is set on the piston to achieve a stable damping effect, and a variable speed shaft is set on the piston, and the cross-sectional area of ​​the variable speed channel is set to be inversely proportional to the pressure value, so that when the pressure increases, the cross-sectional area of ​​the variable speed channel is smaller, the viscous fluid is more difficult to flow, and ultimately the damping effect is better.

[0036] The working principle and usage process of this utility model are as follows: When a steel formwork trolley is required for the irrigation canal project, two slide rails 3 are fixed in the working position. The operator adjusts the position of the trolley body 1 and other structures by cooperating with the slide rails 3 and pulleys 2. If the inclination of a certain steel formwork 44 in the tilt adjustment device 4 needs to be adjusted, the corresponding two first electric telescopic rods 46 are activated, thereby driving the two abutment blocks 45 to move. The two first electric telescopic rods 46 drive the two abutment blocks 45 to move towards the steel formwork 44 and away from the steel formwork 44 respectively, thereby pushing the steel formwork 44 to rotate around the fixed shaft 43 in the U-shaped frame 42 until the steel formwork 44 rotates to the required inclination. Then the operator activates the reduction motor 471 in the adjustment assembly 47, thereby driving the bidirectional lead screw 474. The bidirectional lead screw 474 and the two moving plates 473 are threaded together. The two movable plates 473 are connected, and the movable rods 472 on each of the two movable plates 473 are slidably connected to the vehicle body 1. Therefore, the bidirectional screw 474 drives the two movable plates 473 and their movable rods 472 and connecting plates 41 to move until the two steel templates 44 are moved to the required position for use. The first electric telescopic rod 46 and the reduction motor 471 are electrically connected to the battery 5. When the trolley encounters heavy rain, hail or other weather conditions, the staff can activate the two second electric telescopic rods 65 in the protective buffer device 6, thereby driving the two L-shaped plates 64 to move and adjust the overall area of ​​the two L-shaped plates 64 and the protective plate 66. The dampers 62 and the elastic rubber frame 63 on the two L-shaped frames 61 can buffer the impact encountered by the two L-shaped plates 64 and the protective plate 66, thereby reducing the possibility of the trolley being adversely affected.
