At present, in the process of construction transformation such as new construction, expansion and reconstruction, technical transformation and overhaul of substation, the transfer, butt joint and installation process of switch cabinet are affected by the internal space of high-voltage switch room, indoor cable trench and other factors, and large machinery such as crane and portal crane cannot be used for indoor operation, so the general transfer, installation and positioning mode is to use crane to lift and place the switch cabinet on the hydraulic forklift outside the room, the hydraulic forklift drags the switch cabinet from the outside of the switch room to the indoor area as close to the installation position as possible, and then relies on manpower to unload the switch cabinet from the forklift and move the switch cabinet to the designated installation position.

[0003] The switch cabinet is generally a cuboid-shaped metal armored switch cabinet, which is large in size and weight. In order to ensure the stability during transfer, when the switch cabinet is placed on the two fork arms of the forklift, the length direction of the switch cabinet is consistent with the extension direction of the fork arms, and the width direction of the switch cabinet is consistent with the spacing direction of the two fork arms, so as to fully utilize the size of the fork arms to support the switch cabinet. After the switch cabinet is transferred into the switch room, the posture of the switch cabinet needs to be adjusted according to the arrangement form of the switch cabinet, so that the panel of the switch cabinet faces the designated direction. However, due to the narrow space in the switch room and the cable trench on the ground, the hydraulic forklift needs to move across the two banks of the cable trench, and it is difficult to turn.

DETAILED DESCRIPTION

[0024] ​​​The basic concept of the equipment transfer forklift of the utility model is that the rotating table in the longitudinal state supports the equipment in the transfer process without occupying the space on both sides of the width direction of the frame, and the rotating table in the transverse state changes the equipment orientation and is unloaded, which is suitable for the equipment such as switch cabinets with large differences in length and width dimensions, and facilitates the equipment transfer operation in a narrow space.

[0025] The following will be specifically described in combination with embodiments.

[0026] The embodiment of the equipment transfer forklift of the utility model is as follows:

[0027] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , the equipment transfer forklift comprises a frame, the frame comprises a main mounting frame 1 and a fork arm 2, the fork arm 2 is fixedly provided with a fixed table 4, the fixed table 4 is rotatably provided with a rotating table 3, the rotating table 3 is used for supporting the equipment, the rotating table 3 has a length direction and a width direction, the length of the rotating table 3 is greater than the width of the frame, the width of the rotating table 3 is not greater than the width of the frame, and the rotating table 3 has a longitudinal state in which the width direction of the rotating table 3 is the same as the width direction of the frame and a transverse state in which the length direction of the rotating table 3 is the same as the width direction of the frame in the rotating stroke of the rotating table 3. When the rotating table 3 is in the longitudinal state, the rotating table 3 with a large length dimension can be arranged in the large space in the length direction of the frame, the rotating table 3 is ensured to have sufficient support area for supporting the equipment, the space on both sides of the width direction of the frame is not occupied in the equipment transfer process, and the width of the forklift is prevented from being too large. When the equipment is transferred to the corresponding position, the rotating table 3 is rotated to the transverse state, the length direction of the rotating table 3 is the same as the width direction of the frame, the equipment can be oriented by the rotation of the rotating table 3, the rotating table 3 in the transverse state changes the equipment orientation and then unloads the equipment from the forklift, and the equipment transfer operation in a narrow space is adapted to the equipment such as switch cabinets with large differences in length and width dimensions. While ensuring reliable support of the equipment, the equipment can be rotated on the forklift to adjust the direction before being unloaded, and meanwhile, the width of the forklift is prevented from being too large to affect the passing capacity of the forklift in the transfer process.

[0028] One end of the fork arm 2 in the length direction is fixed to the main mounting frame 1, and the other end is the end of the fork arm 2. The interval direction of the two fork arms 2 is consistent with the width direction of the frame, and the extension direction of the fork arm 2 is consistent with the length direction of the frame. When the transfer equipment is needed, the equipment can be lifted by a crane and placed on the rotating table 3 of the forklift, so as to realize the transfer of the equipment by walking of the forklift. The walking direction of the forklift is consistent with the length direction of the frame. When the rotating table 3 is in a vertical state, the length direction of the rotating table 3 is consistent with the length direction of the fork arm 2, and the rotating table 3 can extend out of the space on the side of the fork arm 2 away from the main mounting frame 1. When the rotating table 3 is in a horizontal state, the length direction of the rotating table 3 is perpendicular to the length direction of the fork arm 2, and the rotating table 3 can extend out of the space on the opposite sides of the two fork arms 2. The installation position of the rotating table 3 on the frame meets the needs of its rotation stroke.

[0029] The rotating table 3 is a frame structure, and a rotating mounting portion for rotating mounting on the fixed table 4 is arranged at the center of the frame structure. The rotating table 3 includes a rectangular frame and a rotating disc 32 arranged in the central region of the rectangular frame, and the rotating mounting portion is arranged at the center of the rotating disc 32. The center of the rotating disc 32 is the center of the rotating table 3. The rectangular frame is a main frame 31, and the main frame 31 has four side frame edges, that is, two short side frame edges arranged in the length direction of the rotating table 3 and two long side frame edges arranged in the width direction of the rotating table 3. The diameter of the rotating disc 32 is smaller than the width of the rotating table 3, and the rotating disc 32 is fixed on the two main frame edges of the main frame 31, which can be fixed by welding. The frame edges of the rotating table 3 of the frame structure are made of profile steel, which ensures the structural strength and is convenient for manufacturing. Using the rotating disc 32 as the rotating mounting portion is beneficial to ensure reliable installation and improve the support area of the equipment. In other embodiments, the rotating table can also be formed by a rectangular plate with sufficient thickness. In other embodiments, a reinforcing beam can be arranged in the middle of the main frame, and the rotating mounting portion is arranged on the reinforcing beam to be rotatably mounted on the fixed table.

[0030] The rotating table 3 is provided with rollers 33 for supporting the equipment, the rotating axis direction of the rollers 33 is consistent with the width direction of the rotating table 3, and the rotating table 3 is provided with limiting structures for limiting the equipment along the length direction of the rotating table 3 when the equipment is transferred. The length and width of the rotating table 3 are slightly larger than the length and width of the bottom of the equipment, the two side frame edges of the main frame 31 of the rotating table 3 are provided with rollers 33, and a plurality of rollers 33 are provided on the same side frame edge along the length direction of the rotating table 3, the rollers 33 slightly protrude from the upper surface of the corresponding frame edge, and the upper surface of the rotating disc 32 is flush with or slightly lower than the top edge of the roller 33, so that the roller 33 can support the bottom surface of the equipment, and at the same time, the rotating disc 32 can also support the equipment. The corresponding frame edge of the main frame 31 can be provided with a groove to avoid the part of the rotating disc 32 fixed on the frame edge, so as to reduce the height of the rotating disc 32. When the equipment is manually pushed off from the forklift, the rolling contact between the rollers 33 and the equipment can reduce the resistance, thereby facilitating the operation. In other embodiments, when the operation resistance is not very large, the rollers can also not be provided.

[0031] The short side frame edge of the main frame 31 of the rotating table 3 is provided with a limiting pin 34, and the same side limiting pin 34 has two limiting pins 34, which are arranged in the width direction of the rotating table 3, the limiting pin 34 constitutes a limiting structure, the corresponding frame edge of the main frame 31 is provided with a insertion hole for the limiting pin 34 to be movably inserted, and the limiting pin 34 protrudes upward to stop the side wall of the equipment, so as to prevent the equipment from sliding along the length direction of the rotating table 3 during the transfer of the equipment. Among them, the limiting pin 34 is arranged at one end of the length direction of the rotating table 3, and the other end is not provided with a limiting structure, and the end provided with the limiting pin 34 is close to the end of the fork arm 2 when the rotating table 3 is in the vertical state, so as to limit the side of the equipment away from the main mounting frame 1 by using the limiting pin 34, thereby avoiding sliding. On the side of the equipment close to the main mounting frame 1, even if the equipment slides greatly, the main mounting frame 1 will also block it, so that dangerous situation will not occur. When the equipment needs to be removed, the limiting pin 34 can be pulled out. In other embodiments, the limiting structures can also be provided at both ends of the length direction of the rotating table. In other embodiments, the limiting structure can also be a swing rod hinged on the main frame, and the swing rod can limit the equipment when it swings to the vertical state, and the main frame is provided with a groove for the swing rod to sink into when it swings to the horizontal state, so as to avoid the swing rod blocking the movement of the equipment.

[0032] The insertion hole for the same limiting pin 34 on the main frame 31 is arranged in plurality along the length direction of the rotating table 3, the limiting pin 34 can be inserted into any insertion hole, the position of the limiting pin 34 can be changed, and it is suitable for equipment of different sizes. Moreover, after the equipment is lifted to the rotating table 3 by the crane, the limiting pin 34 can be selectively inserted into the corresponding insertion hole according to the position of the equipment, without the need to move the equipment, thereby facilitating the operation. In other embodiments, one limiting pin can correspond to only one insertion hole as needed.

[0033] One end of the rotating table 3 in the length direction of the rotating table 3 is a support end, which is close to the end of the fork arm 2 when the rotating table 3 is in the longitudinal state, and the limiting pin 34 is arranged at the support end. The support end is provided with a support structure for supporting on the ground when the device is unloaded, which is a support 35. When the device needs to be unloaded, the fork arm 2 can be supported on the ground as the frame is lowered, and the support 35 can also be supported on the ground. When the rotating table 3 is in the transverse state, the support 35 is supported on one side in the width direction of the frame, and the device slides to the ground from the side where the support 35 is located, which is conducive to the stable support of the forklift on the ground. In other embodiments, the support structure can also not be provided when the weight of the device is not very large.

[0034] The support end of the rotating table 3 protrudes from the end of the fork arm 2 in the length direction of the frame when the rotating table 3 is in the longitudinal state, and the support 35 is integrally arranged on the corresponding short frame side of the main surrounding frame 31. The support 35 protrudes towards the protrusion, and the thickness of the support 35 is greater than the thickness of the long frame side in the up-down direction. The support can be supported on the ground when the rotating table 3 is unloaded in the transverse state, and the support structure is formed by the support 35, which is simple in structure and reliable in support. In other embodiments, bolts can be threadedly connected to the main surrounding frame, and the bolts can be screwed relative to the main surrounding frame to adjust the up-down position as needed.

[0035] The fixed table 4 is a disc structure matched with the rotating disc 32, and the fork arm 2 is provided with a position-avoiding groove for the fixed table 4 to extend into. The fixed table 4 is fixed and supported on the groove bottom of the position-avoiding groove, and the fixed table 4 is fixed on the groove bottoms of the position-avoiding grooves on the opposite sides of the two fork arms 2 through bolts. The bolt hole of the fixed table 4 is a countersunk hole to avoid the bolt head protruding from the upper side of the fixed table 4. The upper side of the fixed table 4 is not higher than the upper side of the fork arm 2, so that after the rotating table 3 is rotated and installed on the fixed table 4, it will not be too far from the fork arm 2. There is a small gap between the lower side of the rotating table 3 and the upper side of the fork arm 2, and the rotating table 3 can be supported on the fork arm 2 when it is slightly inclined, which is conducive to stable support of the device. In other embodiments, the fixed table can be directly fixed on the upper side of the fork arm without setting the position-avoiding groove. In other embodiments, the fixed table can also be formed by two cross beams arranged in cross, and the rotating table is rotated and installed at the intersection of the two cross beams.

[0036] The center of the fixed platform 4 is provided with a mounting structure for the rotating platform 3, and the rotating platform 3 is rotatably mounted on the mounting structure. The rotating platform 3 can be provided with a rotating sleeve fixed on the lower side of the rotating platform 3, and the rotating sleeve is mounted on a rotating shaft so that the rotating platform 3 can rotate relative to the fixed platform 4. The fixed platform 4 is provided with a limiting structure for limiting the rotating stroke of the rotating platform 3. The lower side of the rotating disc 32 is adapted to the upper side of the fixed platform 4, and the upper side of the fixed platform 4 is provided with a limiting protrusion. The limiting protrusion is a sector structure, and the central angle thereof is less than 180°. The opposite side walls of the limiting protrusion along the circumferential direction of the fixed platform 4 form a first horizontal limiting wall 41 and a second horizontal limiting wall 42, respectively. The two side limiting walls form the limiting structure. The lower side of the rotating disc 32 is provided with a limiting matching protrusion, which is a sector structure. The limiting matching protrusion on the lower side of the rotating disc 32 is located on one side of the limiting protrusion on the upper side of the fixed platform 4. The rotating platform 3 has two horizontal states in its rotating stroke, which are a first horizontal state and a second horizontal state, respectively. The rotating platform 3 rotates clockwise from the vertical state to the first horizontal state, and rotates counterclockwise from the vertical state to the second horizontal state. When the rotating platform 3 rotates to the first horizontal state, the limiting matching protrusion is in abutting cooperation with the first horizontal limiting wall 41. When the rotating platform 3 rotates to the second horizontal state, the limiting matching protrusion is in abutting cooperation with the second horizontal limiting wall 42, so as to limit the rotating position of the rotating platform 3 and facilitate the rotation to the position. In other embodiments, the limiting protrusion and the limiting matching protrusion can not be provided, and the relative positions of the fixed platform and the rotating disc can be maintained by positioning pins.

[0037] The main mounting frame 1 is provided with a direct drive motor 9, a battery 8, a hydraulic pump 10, a hydraulic oil cylinder, a steering wheel 6 at the bottom of the frame, a driving walking wheel 5, and a supporting walking wheel at the end of the fork arm 2. The hydraulic pump 10 is connected with a control pull rod 11, and the hydraulic pump 10 can be operated through the control pull rod 11 to realize the lifting of the frame. The battery 8 can supply power to the direct drive motor 9, and the direct drive motor 9 is drivingly connected with the driving walking wheel 5 through a transmission rod 7, so as to drive the driving walking wheel 5 to rotate and realize the walking of the forklift.

[0038] The hydraulic oil cylinder can be controlled by manual pressing to lift the frame and adjust the height of the forklift, so as to avoid the frame being too low to pass through the uneven ground. The wheels of the forklift are all made of relatively soft and wear-resistant aluminum alloy and polyurethane, and are provided with brakes and self-locking functions to prevent the forklift from deviating when the equipment is in place. The direct drive motor is suitable for application on the forklift due to its low speed, large torque, high precision positioning, high response speed, simple structure, small mechanical loss, low noise, less maintenance, etc. It is directly connected with the load without connecting a speed reducer, which saves the mechanical structure such as the speed reducer and improves the precision of the system. At the same time, the efficiency loss caused by the use of the speed reducer is eliminated, and the energy is fully utilized. The battery is used to supply power to the motor, and when the battery output is not good in extremely cold weather, the forklift can also be driven by using a pull disc.

[0039] The main mounting frame 1 is made of heavy column steel and is cold-bent to make the frame stronger and safer, and can bear a weight of 3 t or less. The main mounting frame 1 and the fork arms 2 are connected by flanges, which are convenient for disassembly. The fork arms 2 are designed in a trapezoidal shape, which is wide at the bottom and narrow at the top, so as to increase the contact area of the fork arms 2 with the ground when unloading, and increase the stability when unloading. The fixed table 4 and the fork arms 2 are connected by bolts, which are convenient for disassembly. The connection between the fixed table 4 and the rotating table 3 is in the middle of the two fork arms 2, so that the problem of center of gravity deviation and tilting of the equipment during transportation and rotation does not occur. The rollers 33 on the rotating table 3 are basically level with the upper surface of the rotating disc 32, which utilizes the principle of rolling friction to save labor, assists workers in unloading, and assists the equipment in positioning. The support 35 at one end of the rotating table 3 supports the ground when the equipment is unloading, preventing the forklift from tilting and causing safety accidents, and at the same time, the length of the rotating table 3 is lengthened to adapt to the transportation of larger size equipment. The limit pin 34 can prevent the equipment from shifting or tilting during transportation due to uneven road surface.

[0040] The use process is illustrated by taking the transportation of switch cabinet equipment as an example: operate the hydraulic pump 10 to lower the frame to the lowest position, so that the fork arms 2 are in contact with the ground, and the steering wheels 6 and the traveling wheels are locked, so that the forklift is stable and secure. With the assistance of a crane, the outdoor switch cabinet is pushed onto the forklift by the rollers 33, the limit pin 34 is inserted, and the traveling route is adjusted by controlling the pull rod 11 to control the steering wheels 6. If uneven road surfaces are encountered, the height of the frame is adjusted by the hydraulic mechanism to cross over. The switch cabinet is transferred to the indoor installation position, the rotating table 3 is rotated clockwise or counterclockwise according to the site conditions, the limit pin 34 is pulled out, and the switch cabinet is manually pushed into position.

[0041] The forklift can be used in various complex construction environments. According to the design specification of the cable trench of the 35 kV switch room, it can meet the requirements of transporting the switch cabinet across the cable trench, and solve the problem of space limitation on the construction site. It can reduce the damage to the switch cabinet caused by manual prying, improve work efficiency, and effectively protect product quality. It is suitable for 35 kV indoor power distribution device construction in multiple scenarios. The forklift is widely applicable, can be disassembled and reassembled. It overcomes the difficulty of using hoisting equipment such as cranes under the condition of indoor height restriction, reduces the operation risk, and improves the work efficiency. It can be directly applied to the transportation of high-voltage switch cabinets in substations, and can also be applied to other equipment such as protection screen cabinets, cable reels, capacitor assemblies, grounding transformers, and arc suppression coils.

[0042] Finally, it needs to be explained that the above is only the preferred embodiment of the present application, and is not used to limit the present application, although the present application is described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can modify the technical solutions recorded in the foregoing embodiments without paying creative labor, or make equivalent replacement for part of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
