[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] like Figure 1-2 As shown, the present application relates to a formwork lifting sling applied to wet joints, which includes a base bracket, which is arranged across the wet joint; two moving mechanisms, which are arranged at the front end of the bottom side of the base bracket, and two steering mechanisms, which are arranged at the rear end of the bottom side of the base bracket; and a winch, which is arranged at the top of the base bracket.

[0030] Specifically, when making this sling, first weld a steel pipe with a diameter of 42 mm and a wall thickness of 3.5 mm to make a rectangular basic support with a length of 2 meters, a width of 2 meters, and a height of 2.5 meters. Preferably, the basic support is a square support made of welded steel pipes, and its four surrounding columns extend downward by 50 cm. The appropriate size is convenient for the staff to move flexibly in the basic support, which can be more convenient for construction. The basic support is arranged across the wet joint to realize the lifting of the wet joint; four walking wheels are provided on the bottom side of the basic support for the overall travel of the sling, two moving mechanisms are installed at the front end of the bottom side of the basic support for the movement of this sling, and two steering mechanisms are installed at the rear end of the bottom side of the basic support for the lifting of this sling. The steering of the tool is preferably, the two moving mechanisms are directional wheels, and are provided with a locking device, which is welded on the front end of the bottom side of the basic bracket. When the device needs to be moved, the staff releases the locking mechanism and can move the spreader to the position where the operation is required. After moving to the working position, the staff locks the locking mechanism. In this way, the spreader can be stably placed in the working position to prevent the spreader from sliding, thereby improving safety; preferably, the two steering mechanisms are universal wheels, and are welded on the rear end of the bottom side of the basic bracket. Under the action of the universal wheels, the staff can move the spreader as needed, change direction, and move lightly and conveniently. Preferably, it also includes: a Brake pads are arranged on one side of the two steering mechanisms, so that when the staff encounters a downhill section when moving the spreader, they can use the brake pads to increase the friction between the steering mechanism and the brake pads to achieve the effect of deceleration, avoiding the safety hazard caused by the inconvenience in controlling the walking speed when going downhill; a winch is arranged on the top of the base bracket of the spreader, and when the base bracket is arranged across the wet joint, the winch is also arranged across the wet joint. Preferably, two parallel steel pipes are welded at a distance of 30 cm in the middle of the upper part of the base bracket for placing the winch. Due to the large driving force and strong load capacity of the winch, slight vibration is inevitable during operation, and this vibration poses a certain safety hazard to the lifting operation itself, which may It may cause the traction rope of the winch to become tangled and disorderly, which seriously affects the work. In this case, the winch needs to be fixed before the operation is carried out. Preferably, it also includes: a connector for fixing the winch on the top of the base support. If the winch is not fixed, it is easy for the winch to fall due to the shaking of the base support, causing damage to the winch and even injuring the staff. However, the use of the connector can firmly stabilize the winch on the top of the base support, which can effectively prevent the winch from falling; optionally, the connector can be a phosphate-coated steel wire rope, a galvanized steel wire rope or a stainless steel wire rope; after the winch is fixed, the sling can be flexibly moved to the position where the operation is required to carry out the lifting work.

[0031] From the above description, it can be seen that this application achieves the following technical effects:

[0032] In an embodiment of the present application, a moving mechanism, a steering mechanism and a winch are installed on a base bracket, and are arranged across the wet joint through the base bracket; two moving mechanisms are arranged at the front end of the bottom side of the base bracket, and two steering mechanisms are arranged at the rear end of the bottom side of the base bracket; the winch is arranged on the top of the base bracket, so that the hoist can be safely moved as needed when the template of the wet joint is hoisted, thereby achieving the technical effect of being able to conveniently move the hoisting hoist during hoisting, and thus solving the technical problem of being inconvenient to adjust the direction when moving the hoisting hoist.

[0033] Preferably, it further comprises: a rain cover, which is arranged on the top of the base support and covers the upper side of the hoist, and the rain cover is a quadrangular pyramid rain cover made of transparent plastic. The rain cover is arranged on the top of the sling, first of all, it is necessary to completely cover the hoist to prevent the hoist from getting wet in bad weather such as rain, snow or hail, which may cause a short circuit in the hoist. Optionally, the rain cover can be set to a size larger than the size of the top of the base support, so that the sling can be completely covered. In this way, the workers can be shielded from the sun under the scorching sun, which can effectively prevent the workers from being exposed to the sun, and can also extend the working time and improve work efficiency.

[0034] Preferably, the winch further comprises: two hooks arranged at the bottom of the winch. The two hooks are arranged under the winch to hook the left and right sides of the template to be hoisted, thereby preventing the template to be hoisted from falling during the installation process and improving safety.

[0035] Preferably, the rain cover is detachably mounted on the top of the base support. The rain cover is detachably connected so that workers can install the rain cover according to different weather conditions, thereby improving the efficiency and safety of the operation.

[0036] Optionally, four universal wheels can be installed on the bottom side of the base support and welded to the bottom side of the base support. All the running wheels on the bottom side of the base support are replaced with universal wheels and welded to the bottom ends of the columns extending downward around the base support. In this way, the spreader can be moved and turned more conveniently.

[0037] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
