Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated cabin hoisting, in particular to a prefabricated cabin integral hoisting device. Background Art

[0002] The prefabricated cabin is an outdoor smart substation launched by the State Grid based on the core concept of "standard delivery". The use of prefabricated cabin structure has become an important measure for the secondary equipment carrier in the construction of smart substations. When the position of the prefabricated cabin needs to be adjusted, most of them are lifted by using a hoist cage in conjunction with a crane.

[0003] However, the bottom of the existing lifting devices is mostly designed with iron plates, which will generate great friction with the bottom when loading the prefabricated cabin. The staff needs to use steel pipes to pad the bottom of the prefabricated cabin for sliding and translation. After the transportation is completed, the steel pipes need to be pulled out, otherwise the bottom will be unstable. The loading process is relatively complicated and inconvenient, resulting in reduced work efficiency. In addition, in order to prevent the prefabricated cabin from falling, the existing lifting devices will be installed with fences. However, when the lifting is shaking, the prefabricated cabin will collide with the surrounding guardrails and damage its surface or interior, causing economic losses. Utility Model Content

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 As shown, a prefabricated cabin integral lifting device includes a base 1, roller groups 2 are bolted on both sides of the base 1, and the roller group 2 is composed of a plurality of rollers. The prefabricated cabin can be slid on the bottom of the prefabricated cabin through the roller group 2 to make it easier to enter the device. An auxiliary movement mechanism 3 is arranged inside the base 1, and the auxiliary movement mechanism 3 includes a bevel gear group 31, which is welded to the roller groups 2 on both sides. The number of the bevel gear groups 31 is several, and they are composed of horizontal bevel teeth meshing with vertical bevel teeth, wherein the vertical bevel teeth are aligned with the center line point of each roller, and a transmission shaft 3 is welded to the center of one side of the bevel gear group 31. 2, the transmission shaft 32 is welded with the transverse bevel gear of the bevel gear set 31, a double-axis motor 34 is arranged inside the base 1, and the double-axis motor 34 is selected to have a self-locking function. Active bevel gear rods 33 are fixed to the output shafts on both sides of the double-axis motor 34, and the active bevel gear rods 33 are meshed with the bevel gear sets 31 on both sides. Under the action of the double-axis motor 34, the active bevel gear rods 33 on both sides can be driven to rotate, and the bevel gear sets 31 on the surface of the transmission shaft 32 can be driven to rotate, so that the roller set 2 can be actively rotated, which can assist the translation of the prefabricated cabin when it is transported. The top of the base 1 is welded with a bottom plate 4, and the bottom Support frames 5 are welded on both sides of the top of the seat 1. There are four support frames 5. The support frames 5 are designed in a V shape to ensure that the device can be carried out stably when hoisted and enhance the safety of the device when in use. A lifting ring 6 is welded on the top of the support frame 5. The lifting ring 6 is made of steel and is circular in design, which makes it more convenient to lift during hoisting. A top plate 7 is welded on the inner side of the support frame 5. A clamping mechanism 8 is provided at the bottom of the top plate 7. Under the action of the clamping mechanism 8, the prefabricated cabin can be grabbed during hoisting to prevent it from escaping from the inside during hoisting and causing economic losses. A protective shell 9 is welded on the top of the top plate 7. The protective shell 9 is The hollow design can effectively protect the internal parts from being damaged by external forces. A transport plate 10 is hinged on one side of the base 1. Rollers are arranged on the surface of the transport plate 10. There are several rollers. A locking rod 11 is rotatably connected to the surface of one side of the support frame 5. The transport plate 10 can be folded inward and parallel to one side of the support frame 5. When the locking rod 11 is bent to 90 degrees, the folded transport plate 10 can be fixed and limited, so as to achieve the storage of the transport plate 10 and further protect the prefabricated cabin, and effectively prevent the transport plate 10 from being folded due to gravity, thereby causing it to fall into the inside of the device during lifting, causing a safety hazard.

[0022] The clamping mechanism 8 includes a linkage handle 81, which runs through the interior of the top plate 7 and is rotatably connected to the penetration point. The two ends of the linkage handle 81 are rotatably connected to a connecting rod 82, and the other end of the connecting rod 82 is rotatably hinged to a clamping plate 83. A sliding bar 84 is welded to the top of the clamping plate 83. A sliding groove 87 is provided on the surface of the top plate 7. The inner wall of the sliding groove 87 is slidably connected to the sliding bar 84, so that the clamping plate 83 can slide according to a fixed position. An electric telescopic rod 85 is provided on the top of the top plate 7. One end of the electric telescopic rod 85 is bolted to a sliding bar 84 on one side. Under the action of 85, the sliding bar 84 on one side can slide on the inner wall of the sliding groove 87. Under this action, it can drive the clamping plate 83 on one side to extend and retract, and drive the linkage handle 81 and the connecting rod 82 to link, so that the sliding bar 84 on the other side can be extended and retracted at the same time, which can clamp the prefabricated cabin to prevent it from escaping from the inside of the device during lifting. The inner surface of the clamping plate 83 is provided with an anti-slip gasket 86. The width of the anti-slip gasket 86 is the same as the width of the clamping plate 83, which can increase the friction between the clamping plate 83 and the iron plates on both sides of the prefabricated cabin, and clamp it more effectively.

[0023] Working principle: First, the dual-axis motor 34 is started to drive the active bevel gear rods 33 on both sides to rotate, and drive the bevel gear sets 31 on the surfaces of the transmission shafts 32 on both sides to rotate, so that the roller sets 2 on both sides rotate at the same time, and then the prefabricated cabin is transported to the surface of the transport plate 10 by a forklift or other transportation equipment, and then pushed to move it into the device. Under the action of the rotation of the roller set 2, the prefabricated cabin can be translated into the interior of the device, eliminating the cumbersome process of using steel pipes for translation, and making it more convenient for the staff to carry the prefabricated cabin. After being translated to a suitable position, the dual-axis motor 34 is turned off to stop the rotation of the roller set 2 to prevent the prefabricated cabin from slipping off, and then the electric telescopic rod 85 is started to drive the sliding bar 84 on one side and the clamping plate 83 to slide and retract on the inner wall of the slide groove 87, and through the linkage of the linkage handle 81 and the connecting rod 82, the sliding bar 84 on the other side is retracted at the same time, so as to achieve the effect of clamping the prefabricated cabin, which can effectively prevent the prefabricated cabin from falling off due to shaking during lifting, causing economic losses.
