Detailed ways

An electric equipment lifting and transporting vehicle, including a vehicle body pulled by a traction unit, the key point is that the vehicle body includes a bracket 1, a telescopic mechanism 2, a climbing ladder 3 arranged on both sides of the bracket 1, and a lower end of the climbing ladder 3. The walking wheel 4, the bracket 1 is connected with the ladder 3 by means of the telescopic mechanism 2 and has the freedom of lifting and lowering. The accommodating cabinet 7 is connected with the rotating ring 6 and the rotating shaft 5 by means of a support rod 8 .

In a specific embodiment, as shown in FIGS. 1-3 , two ladders 3 are arranged on both sides of the bracket 1 , and the ladders 3 are connected by connecting rods to enhance the overall stability. The bracket 1 is a support frame with through holes vertically arranged. Both sides of the through holes can be used as walking and workbenches for the staff. The swivel ring 6 is arranged in the through hole on the bracket 1, and the rotating shaft 5 and the swivel ring 6 are arranged coaxially. Both ends of the rotating shaft 5 are hinged with both sides of the bracket 1 respectively. The accommodating cabinet 7 is located on the vertical centerline of the swivel 6 at the highest position, and the accommodating cabinet 7 is located on the extension line of the vertical centerline of the swivel 6 when the accommodating cabinet 7 is at the lowest position, and the accommodating cabinet 7 is hinged to the swivel 6 , and is always in a vertical state with the rotation of the swivel 6 .

When working, use the traction unit to pull the transport vehicle to the working position. The traveling wheel 4 is a universal wheel with a brake pad on it, which can be changed in time according to the change of the traction direction, and the movement is more convenient. The universal wheel is locked and fixed to prevent it from twisting or rolling, ensuring construction safety.

In the initial state of the telescopic mechanism 2 , the accommodating cabinet 7 on the swivel 6 is close to the ground level when the swivel 6 is located at the lowest position, which is convenient for the staff to install new electrical equipment into the accommodating cabinet 7 in advance. Then the staff climbs the ladder 3 to the bracket 1 to dismantle the old electrical equipment. If the height of the electrical equipment is high and the height of the bracket 1 cannot meet the work needs, the staff controls the telescopic end of the telescopic mechanism 2 to extend the bracket 1. and the height of the accommodating cabinet 7 to meet the work requirements. The telescopic mechanism 2 includes a sleeve 9 fixedly connected with the ladder 3 , a screw rod 10 arranged in the sleeve 9 , and a nut matched with the screw rod 10 . The power input shaft 11 of the nut is connected to the drive unit, and the bracket 1 and the screw rod 10 end connections. The drive unit can be a motor, and the staff has a motor controller. The controller controls the motor to drive the power input shaft 11 to drive the nut to rotate. The rotation of the nut makes the screw 10 matched with it rise, so that the bracket 1 rises, and the work is stable and reliable. Sex is high.

After the bracket 1 is raised to an appropriate height, the staff removes the old electrical equipment. The swivel 6 is hinged with two accommodating cabinets 7 arranged symmetrically along the axis of the swivel 6. When a accommodating cabinet 7 is located at the lowest position, Then another accommodating cabinet 7 is located at the highest position. Since the new electrical equipment has been put into an accommodating cabinet 7, the swivel 6 is rotated under the action of gravity of the electrical equipment, and the accommodating cabinet 7 in which the new electrical equipment is placed is turned to a lower position, so that the empty container 7 rotates. The storage cabinet 8 is rotated to a high position, which is convenient for the staff to put the dismantled old electrical equipment into the empty storage cabinet 8 .

A pick-and-place port 13 with a cabinet door 12 is provided on the side walls of the accommodating cabinet 7 at the installation position facing the electrical equipment and the installation position facing away from the electrical equipment. The top of the bracket 1, the pick-and-place port 13 of the accommodating cabinet 7 at the lowest position is lower than the bottom end of the bracket 1, preventing the bracket 1 from interfering with the opening and closing of the cabinet door 12, facilitating the opening of the cabinet door 12, and enabling the power equipment to be picked and placed. The port 13 is placed in the accommodating cabinet 7 . Open the cabinet door 12 facing away from the installation position of the electrical equipment, so that it is convenient to put in new electrical equipment and take out the old electrical equipment, close the cabinet door 12 after putting in or take out, and lock the cabinet door 12 and the body of the accommodating cabinet 7; Opening the cabinet door 12 facing the installation position of the electrical equipment is convenient for putting in the old electrical equipment and taking out the new electrical equipment. It is easy to take and place, and it is not blocked or affected by other components.

The bottom plate of the accommodating cabinet 7 is provided with a guide chute 14 parallel to the axis of the swivel 6 , and the accommodating cabinet 7 is provided with a guide plate 15 that forms a sliding fit with the guide chute 14 . Open the cabinet door 12 facing the installation position, and the guide plate 15 can be pulled out along the axial direction of the swivel 6, so that the staff can put the old electrical equipment on the guide plate 15, and push the guide plate 15 to complete the old electrical equipment. The cooperation of the guide chute 14 and the guide plate 15 makes the guide plate 15 walk accurately without deflection, and it is easier to move the guide plate 15 back and forth, which is convenient for putting in the old electrical equipment, reducing labor intensity, and The operation is safer; then the staff controls the rotation of the swivel 6, which can be artificially rotated, or the rotation of the rotating shaft 5 can be driven by a driving motor. When the accommodating cabinet 7 containing the new electrical equipment is turned to the highest position, the accommodating cabinet 7 containing the old electrical equipment is rotated to the bottom, thereby realizing the lifting and lowering of the new and old electrical equipment. Open the high accommodating cabinet 7 containing the new electrical equipment to face the cabinet door 12 of the installation position, and pull out the guide plate 15 to expose the new electrical equipment, which is convenient for the staff to move the new electrical equipment to the installation position. Install. After the installation is completed, the staff descends to the ground along the ladder 3, and controls the retraction of the telescopic mechanism 2, so that the bracket 1 and the swivel 6 are lowered, the accommodating cabinet 7 where the old electrical equipment is placed is close to the ground, and the upper back facing the installation position is opened. The cabinet door 12 pulls out the guide plate 15, and the old electrical equipment 1 can be taken out.

Similarly, the cabinet door 12 facing the installation position can be opened to pull out the guide plate 15 to take out new electrical equipment, or the cabinet door 12 facing away from the installation position can be opened to pull out the guide plate 15 to place new electrical equipment.

The electric equipment lifting and transporting vehicle involved in the present invention has a simple structure, is convenient to use, reduces labor intensity during the working process, and avoids the occurrence of a fall accident during the lifting and lowering process of the electric equipment by using a pulling rope. The new and old power equipment can be lifted and lowered at the same time, the safety factor is significantly improved, the working time is saved, the work efficiency is improved, and at least two workers can complete the disassembly and assembly work.
