The upper end of the frame 100 away from the wire-receiving mechanism 300 is provided with a handrail 102, so that the operator can pull and move by the handrail 102. The arrangement of the handles 101 and the handrail 102 provides the operator with more force points for moving the device, thereby improving the moving efficiency. The front wheel 400 and the rear wheel 500 are installed at the bottom of the frame 100, and the front wheel 400 is provided with a In order to control the direction, two rear wheels 500 are symmetrically arranged, which can provide balanced support for the frame 100 on the one hand, and improve the moving speed on the other hand; preferably, the front wheel 400 adopts a universal wheel to flexibly adjust the moving direction so that it can be more accurately positioned at the construction point; the two rear wheels 500 adopt inflatable tires, which not only improves the moving speed of the device, but also the height of the inflatable tires is large, which can leave a height space for hanging the cable at the bottom of the frame 100 for the auxiliary take-up part 103 arranged above the rear wheels 500, thereby improving the take-up efficiency. The front wheel 400 is fixedly connected to the frame 100 through the front wheel support frame 104, and the rear wheel 500 is fixedly connected to the frame 100 through the rear wheel support frame 105. The front wheel support frame 104 and the rear wheel support frame 105 are arranged to ensure the balance and stability of the device, and the front wheel support frame 104 is movably connected with a movable leg 600, so that when the device is used in a construction site with uneven or soft soil and a lot of slag, the movable leg 600 can be taken out from the front wheel support frame 104 and contacted with the ground to adjust the height so that the frame 100 can maintain balance and stability, and the movable leg 600 also has a grounding function to improve electrical safety. Optionally, the outer surface of the frame 100 is painted with a waterproof coating to avoid rusting of the frame 100 in the humid environment of the tunnel and to increase the service life of the device.When in use, distribution boxes of different sizes and levels are installed on the upper part of the frame 100 through the clamping frame 200, the span of the clamping frame 200 is adjusted to adapt to the size of the distribution box so that it can firmly clamp the distribution box, and then the smaller cable of the distribution box is rolled up onto the wire-winding mechanism 300, and the excess part of the larger cable of the distribution box is wound onto the auxiliary wire-winding part 103 to avoid the cable from piling up on the tunnel floor; when construction workers are needed to lay cables inside the tunnel for power supply, they can hold the two handles 101 or the handrails 102 to push or pull the device, and the front wheels 400 and The rear wheel 500 enables the device to be movable in all directions on the tunnel ground.

When in use, stretch the clamping plate 202 so that the plane space left by the clamping plate 202 is adapted to the bottom size of the distribution box, and then place the distribution box in the clamping space formed by the clamping plate 202 on the support plate 201, loosen the clamping plate 202 so that it retracts to fit the side of the distribution box under the elastic force of the compression spring, thereby achieving the purpose of clamping and fixing the distribution box. The setting of the clamping plate 202 can limit and guide the side of the distribution box to prevent the distribution box from tipping over, and this method can quickly install and disassemble the distribution box without causing damage to the distribution box, and it is convenient to replace distribution boxes of different levels. Optionally, the clamping plate 202 can also be set as a vertically retractable structure so that its height can be adjusted according to the height size of the distribution box, thereby enhancing the stability of the clamping and the flexibility of application.

[0028] like Figure 1 and Figure 4 As shown, the wire-receiving mechanism 300 includes a winding drum 301 and two wire-blocking discs 302, and the two wire-blocking discs 302 are respectively fixedly connected to the two ends of the winding drum 301 to prevent the cable wire wound on the winding drum 301 from slipping out from the two ends, so that the cable wire can be smoothly wound on the outer wall of the winding drum 301. Optionally, the winding drum 301 adopts a retractable structure design along the axial direction, and the winding drum 301 can be retracted to use a tunnel in a narrow space, and the winding drum 301 can be extended to increase the length of the winding drum 301 so that it can reel more cable wire. A rotating handle 303 is fixed to one end of the wire-blocking disc 302 away from the winding drum 301, and the rotating handle 303 is arranged in a direction perpendicular to the wire-blocking disc 302. A fixed shaft 304 is fixedly installed between the two handles 101 of the frame 100, and one end of the winding drum 301 away from the rotating handle 303 is slidably connected to the fixed shaft 304 so that the winding drum 301 can rotate relative to the fixed shaft 304. Optionally, the fixed shaft 304 is welded to the frame 100. Optionally, the rotating handle 303 is welded to the wire-blocking drum 302. When in use, the operator holds the rotating handle 303 on the wire-blocking plate to rotate it along the axial direction of the wire-blocking drum 302, and the winding drum 301 can be controlled to rotate synchronously, so that the cable can be smoothly wound on the outer wall of the winding drum 301, so as to collect and organize the cable. Optionally, the rotating handle 303 is fixed to the outer periphery of the wire-blocking drum 302 to increase the rotation speed and improve the efficiency of winding. The cable drum 301 is parallel to the axes of the front wheel 400 and the rear wheel 500, so that the cable-winding mechanism 300 can reel in the cable while the front wheel 400 and the rear wheel 500 are moving; the cable drum 301 is located between the two handles 101, and when the cable needs to be released, the cable lowered by the cable drum 301 can be distributed along the moving track of the device, and the cable drum 301 is arranged at the handle 101, so that the operator can collect and organize the cables while moving the device, which makes the reeling of the cables more timely and convenient, greatly improves the cable organization efficiency, avoids the cables from being damaged by accumulation on the tunnel floor, and effectively improves the safety of the distribution box.

[0029] like Figure 1 and Figure 3As shown, the front wheel support frame 104 includes a horizontal cross bar 1042 arranged along the width direction of the frame 100 and two fixed legs 1041 arranged along the height direction of the frame 100, the horizontal cross bar 1042 is fixedly connected to the bottom of the two fixed legs 1041, and the upper part of the fixed legs 1041 is fixedly connected to the handle 101.

On the other hand, the front wheel 400 is installed at the bottom of the horizontal cross bar 1042. When the device is moved to a construction site with uneven or soft soil or a lot of slag, the front wheel 400 is small in size and easily sinks into the soft soil or slag, causing the frame 100 to lose balance. The horizontal cross bar 1042 is set along the width direction of the frame 100, so that when the front wheel 400 sinks into the soft soil or slag, it can contact the ground for auxiliary support, thereby preventing the front wheel 400 from continuing to sink and causing the frame 100 to lose balance and tip over, thereby effectively improving the stability of the device support.

[0030] like Figure 1 , Figure 2 and Figure 3As shown, the fixed leg 1041 is provided with a plurality of protrusions 10411 along the length direction, a limiting ring 10421 is provided on the horizontal cross bar 1042, one end of the movable leg 600 is sleeved with the protrusion 10411 through a ring to axially limit the movable leg 600 to prevent it from falling from the fixed leg 1041, and the plurality of protrusions 10411 cooperate with the ring to enable the movable leg 600 to flexibly adjust the distance from the ground, and the other end of the movable leg 600 is slidably inserted into the limiting ring 10421. The setting of the limiting ring 10421 can prevent the movable leg 600 from shaking too much and falling off during the movement of the device. Specifically, when the device is moved to a construction site with uneven or soft rock and soil and a lot of slag, and the front wheel 400 sinks into the soft rock and soil or slag, causing the device to lose balance, the operator removes the collars of the two movable legs 600 from the protrusions 10411 of the fixed legs 1041, and then drops the bottom of the movable legs 600 onto the ground at the construction site or inserts it into the slag. When the support height that makes the device in a balanced state is reached, the collar of the movable leg 600 is then buckled on the protrusion 10411 of the fixed leg 1041 for axial limit, so that the device completes the switching between the moving and supporting states, and the device remains balanced and stable after being moved into place, thereby improving the stability of the distribution box when in use.

The setting of the front wheel support plate 401 can increase the connection area between the front wheel 400 and the frame 100, making the connection between the front wheel 400 and the horizontal crossbar 1042 more stable. On the other hand, when the device moves to a construction site with more soft rock or slag, the front wheel 400 is small in size and easily sinks into the soft rock or slag, causing the frame 100 to lose balance. The setting of the front wheel support plate 401 can contact the ground for auxiliary support when the front wheel 400 sinks into the soft rock or slag, preventing the front wheel 400 from continuing to sink and causing the frame 100 to lose balance and tip over.
