[0002] A railway is a transportation line consisting of a roadbed, ballast, sleepers, and rails, including bridges, tunnels, and various auxiliary facilities. It not only helps trains run but also supports the construction and maintenance of various auxiliary facilities. Railway transportation is a mode of land transportation suitable for both passenger and freight transport, and is characterized by high efficiency, safety, and strong carrying capacity.

However, the above technical solution can only limit a single construction template through the limiting structure, requiring multiple repeated hoisting operations, and cannot hoist and move multiple construction templates in a unified manner, resulting in a reduction in the hoisting efficiency of construction templates.

[0005] Therefore, those skilled in the art have provided a hoisting device for the construction formwork of railway ballastless track base to solve the problems mentioned in the background art. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A hoisting device for construction formwork of railway ballastless track base includes a movable frame, and a hoisting mechanism is provided on the outside of the movable frame;

[0009] The hoisting mechanism includes two placement frames. Two casters are fixedly connected to the bottom surfaces of both placement frames and the bottom surface of the movable frame. Two first hydraulic cylinders are fixedly connected to the inner wall of the movable frame. A movable plate is fixedly connected to the telescopic ends of the two first hydraulic cylinders. Four second hydraulic cylinders are fixedly connected to the inner wall of the movable plate. Several identical first sliding grooves are formed on the inner wall of the movable frame. Three second sliding grooves are formed on the side of each of the two placement frames that are close to each other. Two electric telescopic rods are fixedly connected to the inner wall of each set of second sliding grooves. Two sliding blocks are fixedly connected to the telescopic ends of each set of electric telescopic rods. A movable clamping plate is fixedly connected to the telescopic ends of each set of second hydraulic cylinders. Anti-slip pads are fixedly connected to the side of each of the two movable clamping plates that are close to each other.

[0010] As a further improvement of this utility model: a dustproof shell is fixedly connected to the outer surface of each of the first hydraulic cylinders, and the upper surface of each dustproof shell is fixedly connected to the inner wall of the moving frame.

[0011] As a further improvement of this utility model: a reinforcing ring is fixedly connected to the outer surface of the telescopic end of each of the first hydraulic cylinders, and the bottom end of each reinforcing ring is fixedly connected to the upper surface of the movable plate.

[0012] As a further improvement of this utility model: two protective seats are fixedly connected to the outer surface of each group of second hydraulic cylinders, and the side of each group of protective seats that is far apart from each other is fixedly connected to the inner wall of the movable plate.

[0013] As a further improvement of this utility model: two reinforcing plates are fixedly connected to the outer surface of the telescopic end of each group of electric telescopic rods, and the left side of each group of reinforcing plates is fixedly connected to the right side of the sliding block.

[0014] As a further improvement of this utility model: the inner wall of each set of reinforcing plates is threaded with several identical fixing bolts, and the outer surface of each set of fixing bolts is threaded to the inner wall of the sliding block.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model, through the cooperation of a movable frame, a first hydraulic cylinder, a second hydraulic cylinder, a movable plate, and a movable clamping plate, facilitates the hoisting of construction templates. The casters allow for easy movement of the entire device, enhancing its usability. Furthermore, the cooperation of a placement frame, a first sliding groove, a second sliding groove, an electric telescopic rod, and a sliding block enables the hoisting and transport of multiple construction templates at once, enhancing the device's practicality. This effectively avoids the problem of hoisting equipment being limited to a single template, requiring multiple repeated hoisting operations, and failing to hoist and transport multiple templates simultaneously, thus reducing the efficiency of construction template hoisting.

[0023] Please see Figure 1-5A hoisting device for construction templates of ballastless track bases for railways includes a mobile frame 1. A hoisting mechanism 2 is provided on the outer side of the mobile frame 1. The hoisting mechanism 2 includes two placement frames 201. Two casters 202 are fixedly connected to the bottom surfaces of the two placement frames 201 and the bottom surface of the mobile frame 1. Two first hydraulic cylinders 205 are fixedly connected to the inner wall of the mobile frame 1. A dustproof shell 3 is fixedly connected to the outer surface of each first hydraulic cylinder 205. The upper surface of each dustproof shell 3 is fixedly connected to the inner wall of the mobile frame 1. The dustproof shell 3 can protect the first hydraulic cylinder 205 and prevent it from being disturbed by external factors during use.

[0024] The telescopic ends of the two first hydraulic cylinders 205 are fixedly connected to a movable plate 204. The inner wall of the movable plate 204 is fixedly connected to four second hydraulic cylinders 206. The outer surface of the telescopic end of each first hydraulic cylinder 205 is fixedly connected to a reinforcing ring 4. The bottom end of each reinforcing ring 4 is fixedly connected to the upper surface of the movable plate 204. Through the reinforcing ring 4, the first hydraulic cylinders 205 and the movable plate 204 can be reinforced, thereby enhancing the stability of the device.

[0025] The inner wall of the movable frame 1 is provided with several identical first sliding grooves 203. The two placement frames 201 are provided with three second sliding grooves 209 on the side that is close to each other. The outer surface of each group of second hydraulic cylinders 206 is fixedly connected with two protective seats 5. The side of each group of protective seats 5 that is far from each other is fixedly connected to the inner wall of the movable plate 204. Through the protective seats 5, the second hydraulic cylinders 206 can be protected, which plays a strong protective role and prevents them from being damaged by the outside world during use.

[0026] Two electric telescopic rods 210 are fixedly connected to the inner wall of each group of second slide grooves 209. Two sliding blocks 211 are fixedly connected to the telescopic end of each group of electric telescopic rods 210. Two reinforcing plates 6 are fixedly connected to the outer surface of the telescopic end of each group of electric telescopic rods 210. The left side of each group of reinforcing plates 6 is fixedly connected to the right side of the sliding block 211. Through the reinforcing plates 6, the electric telescopic rods 210 and sliding blocks 211 can be reinforced to prevent their position from shifting and becoming unstable during operation.

[0027] Each set of second hydraulic cylinders 206 has a movable clamping plate 207 fixedly connected to its telescopic end. Anti-slip pads 208 are fixedly connected to the side of the two movable clamping plates 207 that are close to each other. Several identical fixing bolts 7 are threadedly connected to the inner wall of each set of reinforcing plates 6. The outer surface of each set of fixing bolts 7 is threadedly connected to the inner wall of the sliding block 211. The fixing bolts 7 can reinforce the reinforcing plate 6 and the sliding block 211 to prevent them from swaying or shaking during use.

[0028] The working principle of this utility model is as follows: In use, the entire device is first moved to a suitable area by the universal wheels 202. Then, the extension end of the first hydraulic cylinder 205 is extended, driving the movable plate 204 to descend until it is above the construction template. Next, the extension end of the second hydraulic cylinder 206 is extended, driving the movable clamping plate 207 to move, thereby fixing and clamping the construction template. When it is necessary to buffer the construction template, the first hydraulic cylinder 205 is retracted, driving the construction template to rise. Then, the electric extension... The telescopic end of the rod 210 extends, pushing the sliding block 211 to move into the second slide groove 209. Then, the clamped construction template is placed on the two sliding blocks 211. The telescopic end of the electric telescopic rod 210 retracts, which can drive the construction template to move and achieve the purpose of buffering. Thus, when a certain number of construction templates are stored, they can be transferred at one time. This can effectively avoid the problem that the hoisting equipment can only limit the position of a single construction template, requiring multiple repeated hoisting operations, and cannot hoist and transfer multiple construction templates at the same time, resulting in a decrease in the hoisting efficiency of construction templates.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
