[0037] The embodiments of the utility model will be described below. Figs. 1 to 3 The embodiments of the utility model will be described below.

[0038] The protective wall outer electric box lifting structure in the embodiment comprises a rack 1, and further comprises:

[0039] Lifting mechanism, the lifting mechanism is arranged on the rack 1;

[0040] Box 2, the box 2 is arranged on the lifting mechanism, and the lifting mechanism drives the box 2 to lift;

[0041] Drive device, the drive device is arranged on the rack 1, and the drive device is in transmission connection with the lifting mechanism;The drive device is used for providing power for the lifting mechanism;

[0042] Guiding mechanism, the guiding mechanism is arranged on the rack 1, and the guiding mechanism is used to guide the lifting process of the box 2.

[0043] In the whole protective wall outer electric box lifting structure, the rack 1 is used as a basic support component, is installed behind the protective wall body A, the rack 1 bottom is connected with the bridge protective wall body A foundation by pre-buried or expansion bolt, guarantees that the whole lifting structure is stable, does not displace, shakes, provides installation environment for other components;

[0044] The lifting mechanism is installed on the rack 1 and is a core component for lifting the box 2. The lifting mechanism includes a reduction box 3, a winding drum 31, and a steel wire rope 32. The reduction box 3 can be a worm gear reduction box 3 with self-locking function; the reduction box 3 and the winding drum 31 are fixed stably at one end of the top of the rack 1, the output shaft of the driving device is connected with the input shaft of the reduction box 3 through a shaft coupling, and the output shaft of the reduction box 3 is connected with the winding drum 31 by a key. The winding drum 31 is a cylindrical structure, and the surface can wind the steel wire rope 32. When the driving device operates, whether it is power driven by the motor 4 or manually driven by the hand crank 41, the power is first transmitted to the reduction box 3, and the reduction box 3 drives the winding drum 31 to rotate after speed change. One end of the steel wire rope 32 is fixed on the winding drum 31, and the other end is connected to the other end of the top of the rack 1 after passing through the fixed pulley 21 at the bottom of the box 2, and the steel wire rope 32 is retracted and released by the forward and reverse rotation of the winding drum 31, so as to realize the stable lifting of the box 2. This design enables the box 2 to accurately adjust the height according to actual needs, meeting the requirements of the position of the box 2 in different scenes. When the box 2 behind the protective wall A needs to be maintained, the box 2 can be lifted and lowered by the cooperation of the lifting mechanism and the driving device, and the lifting process of the box 2 can be smoothly guided by the guide mechanism, so as to lift the box 2 to a suitable maintenance height, so that the maintenance personnel can carry out the maintenance work of the box 2 without the help of additional large equipment, improving the maintenance efficiency.

[0045] The box 2 is placed on the lifting mechanism and vertically displaced under the driving of the lifting mechanism. In this process, the guide mechanism can guide the lifting process of the box 2. The guide mechanism is arranged between the box 2 and the rack 1 and includes a sliding rail 6, a sliding block 61, a limiting block 62, and a buffer spring 63. The sliding rail 6 is fixed vertically on the rack 1, and the sliding block 61 is installed on the box 2, which tightly cooperate to ensure that the box 2 can only move in the vertical direction during the lifting process, avoiding horizontal displacement or tilting. When the box 2 rises, the sliding block 61 moves upward along the sliding rail 6, and once it touches the limiting block 62 at the top end, the box 2 stops rising to prevent safety accidents caused by excessive rising. When the box 2 descends to the lowest position, the sliding block 61 presses the buffer spring 63 at the bottom of the sliding rail 6, which absorbs and disperses the impact force generated by the descent of the box 2, protecting the box 2 and the rack 1 from impact.

[0046] The driving device is arranged on the frame 1 and is in transmission connection with the lifting mechanism to provide power source for the whole lifting action. The driving device includes two driving modes of the motor 4 and the hand crank 41. The motor 4 serves as the main driving source, the output shaft of which is directly connected with the input shaft of the speed reducer 3. After being started by power supply, the motor 4 generates rotary power which is transmitted to the speed reducer 3 to drive the winding drum 31 to rotate, thereby realizing the rapid lifting of the box body 2 and being easy to operate and quick in response. The hand crank 41 serves as the standby driving mode and is connected with the input shaft of the speed reducer 3. When the motor 4 fails or there is no power supply, the staff manually rotates the hand crank 41, the power is transmitted to the speed reducer 3 to drive the winding drum 31 to wind or unwind the steel wire rope 32, thereby completing the lifting action of the box body 2 and ensuring that the box body 2 can normally lift under various complex conditions.

[0047] The wire harness protection tank chain 5 is connected to the bottom of the box body 2 at one end and to the bottom of the frame 1 at the other end. The wire harness protection tank chain 5 includes a plurality of chain links which are connected through pin shafts to form a structure which can be flexibly bent and has a certain rigidity. When the electric box is lifted, one end of the wire harness protection tank chain 5 is fixed to the bottom of the frame 1 and the other end is correspondingly stretched or contracted with the lifting of the electric box. Due to the structural characteristics of the tank chain, it generates a constraint force on the electric box during the stretching and contracting process to guide the electric box to lift along the set track. The wire harness protection tank chain 5 can simultaneously protect the wire harness connected between the box body 2 and the frame 1 from being pulled, squeezed or worn to prolong the service life of the wire harness and improve the stability of the box body 2 system. The wire slot 11 is arranged at the bottom of the frame 1 to accommodate and arrange the electric wires and cables connected between the box body 2 and external equipment, so that the layout of the wires is neat and orderly, which is convenient for daily maintenance and fault troubleshooting and provides physical protection for the wire harness to avoid damage caused by external force.
