[0031] Example: See Figure 1 , Figure 2 and Figure 3 As shown, an integrated mobile cart for a bridge culvert distribution box of an embodiment is shown, wherein the cart includes a frame body 1; a winding bracket 2 fixed on the frame body 1; a limit assembly 4 movably connected to the frame body 1, for locking the distribution box 3 loaded on the frame body 1; the limit assembly 4 includes: a horizontal portion 41 and a vertical portion 42 connected to each other in a nearly vertical state; a counterweight portion 43 connected at the intersection of the horizontal portion 41 and the vertical portion 42; and a limit block 44 connected to one end of the vertical portion 42 and a friction block 411 installed on the surface of the horizontal portion 41.

[0032] In this embodiment, Figure 4 As shown, a through hole 45 is provided at the intersection of the horizontal portion 41 , the vertical portion 42 and the counterweight portion 43 , a C-shaped spring leaf 6 is installed in the through hole 45 , and an arc segment notch 61 is formed between the C-shaped spring leaf 6 and the through hole 45 .

[0033] In this embodiment, Figure 5 As shown, a rotating shaft 5 is fixedly arranged in the frame body 1, the rotating shaft 5 passes through the C-shaped spring 6, and the rotating shaft 5 is provided with an arc segment protrusion 51, and the arc length of the arc segment protrusion 51 is smaller than the arc length of the arc segment notch 61. The limiting assembly 4 can rotate around the rotating shaft 5, and the rotation stroke is limited by the rotation angle cooperation between the arc segment protrusion 51 and the arc segment notch 61.

[0034] In this embodiment, continue to refer to Figure 4 , Figure 5and Figure 6 As shown, the vertical portion 42, the horizontal portion 41 and the counterweight 43 are distributed in a triangle around the rotation direction of the rotating shaft 5, and the weight of the counterweight 43 is greater than the sum of the weights of the vertical portion 42 and the horizontal portion 41. When the limit assembly 4 is in the initial state, one end of the horizontal portion 41 is tilted upward, and when the limit assembly 4 is in the working state, the horizontal portion 41 is pressed downward by the distribution box 3 and is in a horizontal state.

[0035] In this embodiment, Figure 2 As shown, there are two limit assemblies 4, which are symmetrically arranged on the frame body 1, and the distribution box 3 is located between the two limit assemblies 4. There are three limit assemblies 4, which are arranged on the frame body 1 in a shape of a triangle, and the distribution box 3 is located between the three limit assemblies 4.

[0036] In this embodiment, Figure 1 As shown, the cart further includes a handle portion 13 for pushing, and rollers 14 are installed at the bottom of the cart.

[0037] The characteristics and functions of the present invention can be further understood through the following description.

[0038] This embodiment is mainly to solve the problem in the prior art that the distribution boxes are temporarily built when in use, resulting in cables being piled up everywhere, causing construction safety and inconvenience in moving the distribution boxes.

[0039] Therefore, the integrated mobile trolley of the bridge culvert distribution box of this embodiment is integrated with a limit assembly 4 for installing, positioning and locking the distribution box 3. The trolley includes a frame body 1. The frame body 1 can preferably be a double-layer frame including a first frame layer 11 and a second frame layer 12. When the cable is too long, part of the cable can be wound on the winding bracket 2, and part of the cable can be placed on the second frame layer 12. In other embodiments, the length, width, height and number of layers of the frame can be customized according to specific construction conditions, which will not be repeated here. The frame body 1 also has a handle portion 13 for pushing and moving and a roller 14 for rolling arranged at the bottom of the frame body 1. The limit assembly 4 is installed on the first frame layer 11 of the frame body 1. The limit assembly 4 can be two, symmetrically arranged, and the distribution box 3 is arranged between the two limit assemblies 4; or three, arranged in a herringbone shape in the first frame layer 11 of the frame body 1, and the distribution box 3 is arranged between the three limit assemblies 4 (such as Figure 2 As shown). The initial position of the limiter assembly 4 is as follows Figure 5 As shown, the horizontal portion 41 tilts upwards. This is because the weight of the counterweight 43 is greater than the weight of the horizontal portion 41 and the vertical portion 42. In addition, the arc segment notch 61 of the C-shaped spring 6 cooperates with the arc segment protrusion 51 of the shaft 5. Therefore, the counterweight 43 on the right half of the shaft 5 will drop and tilt the horizontal portion 41 upwards (as shown in FIG. Figure 5As shown, when the distribution box 3 presses on the horizontal part 41, the horizontal part 41 gradually tends to be horizontal, and due to the cooperation between the arc notch 61 of the C-shaped spring piece 6 and the arc convex block 51 of the rotating shaft 5, the horizontal part 41 will remain in a horizontal state unchanged.

[0040] Combined with Figure 1 , Figure 3 , Figure 5 and Figure 6 as shown, the working principle of the integrated mobile cart of the bridge and culvert distribution box in this embodiment is as follows:

[0041] First, when the distribution box 3 is not loaded on the frame body 1, the state of the limit component 4 is as shown in Figure 3 a, which is the state where the horizontal part 41 tilts upward.

[0042] Then, gradually load the distribution box 3 into two or three limit components 4 of the frame body 1. The distribution box 3 gradually presses down the horizontal part 41 to make it tend to be horizontal, and finally contacts the friction block 411 of the horizontal part 41. The friction block 411 can increase the friction between the distribution box 3 and the horizontal part 41, so that the distribution box 3 will not shake during the movement, as shown in Figure 3 b.

[0043] Next, when the horizontal part 41 gradually tends to be horizontal, the limit block 44 on the vertical part 42 gradually approaches and finally contacts the distribution box 3 to firmly lock the distribution box 3 (as shown in Figure 1 and Figure 2 shown). Theoretically, the weight of the distribution box 3 is proportional to the clamping force of the limit block 44. The limit block 44 and the friction block 411 jointly increase the friction force on the distribution box 3 and lock the distribution box 3.

[0044] When removing the distribution box 3, just pick up the distribution box 3 upward, and the weight of the counterweight block 43 will tilt the horizontal part 41 up and return to its original position again.

[0045] Preferably, the limit block 44 is a three-layer structure, including a base layer 441, a buffer layer 442 and a locking layer 443 respectively. The hardness of the material gradually decreases, or the softness gradually increases. The locking layer 443 that finally contacts the distribution box 3 can be made of a material such as soft rubber, which is both soft and has friction.

[0046] The cable (not shown) of the distribution box 3 can be wound around the winding bracket 2, which solves the problem of the traditional temporary power cable being stacked randomly on the ground.

[0047] In this embodiment, a double-layer trolley is made, and a brake device is installed on the wheel. A secondary distribution box and multiple tertiary distribution boxes are fixed on the upper layer of the trolley frame to ensure the effective implementation of "one machine, one switch, one box, and one leak" and meet the safety distance between the secondary distribution box and the tertiary distribution box; the cable and the grounding wire are placed on the lower layer of the frame to ensure that the cable is not crushed. The frame of corresponding length can be made according to the actual number of electrical appliances. A more suitable trolley is improved according to the usage. The previous temporary power use is changed from chaotic to the current temporary power use is standardized, which improves the standardization level. The three-level power distribution system and "one machine, one switch, one box, and one leak" can be implemented more effectively. The structure is simple, easy to use, convenient to transfer, and has a long service life. The improved trolley has increased width, shortened length, and effectively reduced the occupied space; the four small wheels are improved into two large wheels, which is more convenient to walk and also reduces the cost. In other embodiments, the frame body 1 can be made of galvanized square tubes, which are suitable in price, light in weight, convenient and durable. Other accessories can be vacuum rubber wheels, which are reasonably priced, wear-resistant, non-slip and easy to replace.

[0048] In summary, the integrated mobile cart of the bridge culvert distribution box of the utility model is provided with a winding bracket on the main body of the frame, and the cables of the distribution box can be wound on the winding bracket, so that they will not be scattered and piled on the ground and crushed, thereby ensuring the integrity of the cables, preventing cable damage, and preventing workers from tripping over the cables, thereby improving the safety of electricity use. In addition, a limit assembly is provided on the main body of the frame, which can limit and fix the distribution box, so that the cart will not overturn during movement, further improving the safety of electricity use.
