Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically to an outdoor installation and hoisting mechanism for a transformer box. Background Technology

[0002] Transformer boxes are crucial devices in power systems used for distributing electrical energy and are widely used in outdoor settings. When installed outdoors, they must withstand complex environments such as wind, rain, and temperature variations. Installation must adhere to regulations to ensure safety and reliability, guarantee a stable and convenient power supply, and provide strong support for outdoor electrical equipment.

[0003] Utility model patent CN222181563U discloses a transformer box lifting device. This device includes a gantry frame, a lifting component, a tilting component, a tilting shell, and a clamping component. The tilting shell has a cavity for accommodating the transformer box. The clamping component is located outside the cavity and includes several movable clamping members that confine the transformer box within the cavity. The lifting component is mounted on the gantry frame, and the tilting component is mounted on the lifting component. The tilting component is used to tilt the tilting shell, and the lifting component is used to lift both the tilting component and the tilting shell. By placing the transformer box into the cavity and using the clamping members to hold or hold the box to fix its position within the cavity, the lifting component lifts the tilting shell. Once the tilting shell is raised to a preset position, the tilting component tilts the shell, ensuring the transformer box remains stable and safe throughout the lifting and tilting process.

[0004] The transformer box lifting device adopts a gantry structure, which is large in size and lacks moving parts. It needs to rely on external lifting equipment for transfer, making it difficult to move flexibly to different outdoor installation sites. It is not suitable for outdoor installation scenarios with complex terrain and scattered sites. Furthermore, the gantry structure limits its use in narrow or space-constrained outdoor environments. In view of this, we propose an outdoor installation and lifting mechanism for transformer boxes. Utility Model Content

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0041] Please see Figures 1-8An outdoor installation hoisting mechanism for a transformer box includes two hoisting mechanisms 100 respectively disposed at both ends of the transformer box 200. Each hoisting mechanism 100 includes a central base assembly 110, two first support legs 120 rotatably connected to the left and right ends of the central base assembly 110, two second support legs 130 rotatably connected to the left and right ends of the central base assembly 110, and a lifting assembly 140 disposed on the central base assembly 110. The first support legs 120 and second support legs 130 support the central base assembly 110, and the lifting assembly 140 is capable of vertical movement within the central base assembly 110. By providing two hoisting mechanisms 100 to support both ends of the transformer box 200 respectively, and cooperating with the rotatably connected first support legs 120 and second support legs 130, the support angle can be flexibly adjusted to adapt to different terrains, while simultaneously providing a stable support foundation for the lifting assembly 140.

[0042] like Figure 3 , Figure 6 and Figure 7 As shown, in this utility model, the center seat assembly 110 includes a sleeve post 111. A pair of protrusions 112 are fixed at both ends of the sleeve post 111. A fixing post 113 is fixed between the ends of each pair of protrusions 112. A pair of rotating grooves 1131 are provided on the fixing post 113. The first supporting leg 120 is provided with a first sleeve post 121 at its head end, and the second supporting leg 130 is provided with a second sleeve post 131 at its head end. The first sleeve post 121 is fitted in one of the rotating grooves 1131, and the second sleeve post 131 is fitted in the other rotating groove 1131. Under the action of the first sleeve post 121 and the second sleeve post 131, the first supporting leg 120 and the second supporting leg 130 are rotatably connected to the fixing post 113. The protrusion 112 and the fixed column 113 form a support shaft structure. The first set of columns 121 and the second set of columns 131 are sleeved on the fixed column 113 through the rotating groove 1131, so as to realize the rotation adjustment of the first support leg 120 and the second support leg 130, which is convenient to adjust the support span or fold and store according to the terrain.

[0043] like Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, specifically, the bottom of the rotating groove 1131 is provided with several pin holes 1132, and each rotating groove 1131 is equipped with a pin 114. The outer surface of the first sleeve post 121 is provided with a first insertion hole 1211, and the outer surface of the second sleeve post 131 is provided with a second insertion hole 1311. The pin 114 is inserted into the corresponding pin hole 1132 through the first insertion hole 1211 and the second insertion hole 1311 respectively. The outer surface of the end of the pin 114 is threaded, and the wall of the pin hole 1132 is threaded. After the pin 114 is inserted into the pin hole 1132, it can be screwed into the pin hole 1132 by rotating the pin 114. By using the pin 114 to pass through the first insertion hole 1211 and the second insertion hole 1311 and screw it into the pin hole 1132 respectively, the first support leg 120 and the second support leg 130 can be fixed at the preset angle positions of the two rotating grooves 1131 respectively. The pin 114 has a handle 1141 at its head end, which facilitates the insertion, removal and tightening of the pin 114 to ensure that the support angle is fixed and reliable.

[0044] like Figure 2 , Figure 6 and Figure 7 As shown, the first support leg 120 is further equipped with a first caster wheel 122 at its end, and the second support leg 130 is equipped with a second caster wheel 132 at its end. The first caster wheel 122 and the second caster wheel 132 enable the device to move flexibly before and after lifting, adapt to the horizontal movement requirements of the outdoor ground, improve transportation convenience, and move the transformer box 200 to the required installation position.

[0045] like Figure 3 and Figure 5 As shown, a threaded screw 115 is fitted inside the sleeve 111. The bottom end of the sleeve 111 is closed and a rotary motor 1151 is installed thereon. The output shaft of the rotary motor 1151 is coaxially connected to the threaded screw 115. By starting the rotary motor 1151, the rotary motor 1151 can drive the threaded screw 115 to rotate. Through the threaded engagement, the fixed block 1411 moves vertically along the sleeve 111, realizing the lifting function of the lifting assembly 140. The top end of the threaded screw 115 passes through the fixed block 1411 and is provided with a stop post 1152. The stop post 1152 is used to prevent the fixed block 1411 from detaching from the threaded screw 115. The stop post 1152 limits the upward limit position of the fixed block 1411, preventing it from detaching from the threaded screw 115 and ensuring structural safety.

[0046] like Figure 1 , Figure 2 and Figure 8As shown, it is worth noting that the lifting assembly 140 includes a movable rod 141 sleeved in the sleeve column 111 and movable along the sleeve column 111, a cross arm 142 fixed to the top of the movable rod 141, and two booms 1421 respectively fixed to the beginning and end of the cross arm 142. A fixing block 1411 is fixed inside the bottom of the movable rod 141. A threaded screw 115 passes through the fixing block 1411 and is threadedly connected to the fixing block 1411. A lifting ring 1422 is fixed at the bottom of the boom 1421. Lifting rings 210 are installed at the four corners of the top of the transformer box 200. A lifting rope 300 is hooked between the lifting ring 210 and the corresponding lifting ring 1422, so that the end of the boom 1421 lifts the transformer box 200 through the lifting rope 300. The movable rod 141 is linked with the threaded screw 115 through the fixed block 1411, which drives the horizontal arm 142 and the boom 1421 to rise and fall. The lifting ring 1422 and the lifting ring 210 are connected by the lifting rope 300 to achieve stable lifting of the transformer box 200.

[0047] It is worth noting that the rotary motor 1151 involved in this utility model is existing conventional technology, and will not be described in detail here.

[0048] When using the outdoor installation hoisting mechanism for the transformer box in this embodiment, firstly, according to the terrain of the outdoor installation site, the rotation angle of the first support leg 120 and the second support leg 130 relative to the fixed column 113 is adjusted, and the two pins 114 are passed through the first insertion hole 1211 and the second insertion hole 1311 respectively and screwed into the corresponding pin hole 1132, so that the support leg can be fixed at a suitable support span position to ensure stable support of the center seat assembly 110;

[0049] Then, the pushing device moves to both sides of the transformer box 200 via the first universal wheel 122 and the second universal wheel 132, and hangs the lifting rope 300 on the lifting ring 210 of the transformer box 200 and the lifting ring 1422 of the boom 1421 respectively to complete the lifting connection.

[0050] Next, start the rotary motor 1151, which drives the threaded screw 115 to rotate. Through the fixed block 1411, the movable rod 141, the cross arm 142 and the boom 1421 are driven to rise vertically, raising the transformer box 200 to the preset height.

[0051] Finally, the transformer box 200 is transported to the installation position again using the caster wheels. After being slowly lowered to the designated height, the hoisting rope 300 is disconnected, and the installation is completed.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
