Description

Technical Field

[0001] The utility model belongs to the field of devices for assisting manual movement of heavy loads, and particularly relates to a cabinet relocation tool. Background Art

[0002] With the continuous development of automation technology, a large number of automated instrument systems are involved in industries such as electric power, petroleum, and chemical industry, and it is necessary to establish electrical, instrument, and communication machine rooms for automated control. In order to save installation space and facilitate maintenance and management, the cabinets in the machine room are arranged in rows. With the construction of new, renovated (expanded) projects in the later stage, the reserved spare channels and maintenance spaces in the early stage are very likely to be occupied. During the subsequent equipment update and expansion construction process, it is difficult to relocate the cabinets of precision electronic components such as electrical, instrument, and communication that have been integrated in the factory to the designated position. The main reasons are not only that the cabinets are relatively heavy and shock absorption and anti-falling measures need to be taken, but also that: if the cabinets are accessed through the original spare channel or maintenance space, the services in the in-use cabinets need to be interrupted, and the power or signal cables need to be temporarily removed. After the cabinets planned to be updated are in place, the wiring needs to be restored. Such relocation will generate a great deal of workload and ineffective labor, occupying resources and consuming time.

[0003] Taking the upgrade and transformation construction of a certain system in Zhongyuan Oilfield as an example, more than 60 new and old cabinets need to be relocated and replaced. If the method of accessing the cabinets through the original spare channel or maintenance space is adopted, the efficiency of cabinet relocation will be low, and the labor cost and production losses will be serious.

[0021] Furthermore, through the scheme setting of the extension bracket, the stable transportation and unloading of the cabinet on the other side of the window (relative to one side of the base frame) can be realized, so as to realize the efficient progress of the cabinet relocation without changing the installation position of other base frames.

[0022] In addition, through the design of the rolling mechanism on the base frame, the transportation resistance of the cabinet on the base frame and the extension bracket can be reduced, and further manpower input can be saved.

[0023] The technical solution of the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Embodiment 1

[0025] The cabinet relocation tool in this embodiment, as Figure 1 and Figure 2 shown, includes a base frame 1 and an extension bracket 2.

[0026] The base frame 1 mainly serves as a loading tool for the cabinet, which should be able to bear the weight of the cabinet and can be made of common steel materials such as round steel on the construction site. The base frame 1 has a lapping end 3 for lapping with the window wall and a first supporting end 4 for supporting on the ground outside or inside the window; after the computer room window is opened, one end of the base frame 1 lapped on the window wall forms the lapping end 3, and the other end supports on the ground outside the computer room (when the new cabinet is moved in) or inside the computer room (when the old cabinet is moved out) to form the first supporting end 4.

[0027] The first support end 4 of the base frame 1 is connected with a first foot 5 with adjustable height. The first foot 5 is set to have adjustable height mainly to meet the two attitude requirements for the relocation of the cabinet. Taking the relocation of a new cabinet as an example, after the mobile trolley moves the cabinet to the relocation position, first the first support end 4 of the base frame 1 is placed on the ground, and the base frame 1 presents an inclined position to slowly place the cabinet on the base frame 1 in an inclined manner. Then the base frame 1 is lifted to be flush with the window sill, and the base frame 1 presents a horizontal position to facilitate pushing the cabinet through the window sill and into the indoor side.

[0028] The first foot 5 has a height adjustable mechanism, and the height adjustable mechanism can adjust the height of the first foot 5 to achieve the above two attitudes of the inclined position and the horizontal position of the base frame 1. As Figure 2 shown, the first foot 5 includes a first short tube 50 connected to the bottom of the first support end 4, a first support rod 51 movably inserted into the first short tube 50, and a first base 52 connected to the bottom of the first support rod 51. In this way, when the first support rod 51 is inserted into the first short tube 50, the base frame 1 is adjusted to the horizontal position; when the first support rod 51 is pulled out of the first short tube 50, the base frame 1 is adjusted to the inclined position. In other implementation cases, a steel frame with a height equivalent to that of the window sill can also be directly used as the first foot 5, and the steel frame is welded by several round steel bars into a firm rectangular parallelepiped frame.

[0029] A stop member 6 for restricting the relative movement of the base frame relative to the window wall during the transportation of the cabinet is provided at the overlapping end 3 of the base frame 1. The stop member 6 is mainly used to form a stop fit with the wall, so as to prevent the base frame 1 from moving relatively during the transportation of the cabinet, and improve the efficiency and stability of the transportation of the cabinet. Any stop member 6 that can effectively achieve the above stop function can be adopted, such as a protrusion, a block, etc. provided at the lower part of the overlapping end 3 of the base frame.

[0030] A rolling mechanism for facilitating the transportation of the cabinet is provided on the base frame 1. In this way, when transporting the cabinet on the base frame, the rolling cooperation between the cabinet and the rolling mechanism can be utilized to push the cabinet to move with less force. As Figure 1 shown, the base frame 1 includes a pair of cross beams arranged at intervals relatively, and roller bars rotatably connected between the cross beams. There are multiple roller bars and they are arranged at intervals along the length direction of the cross beams. For the convenience of manufacturing the base frame, on-site materials can be directly used. For example, two main rib round steel bars 7 are arranged parallel to each other as the cross beams, and secondary rib round steel bars 8 are welded between the two main rib round steel bars 7. The secondary rib round steel bars 8 are perpendicular to the main rib round steel bars 7 and are evenly spaced between the two main rib round steel bars 7. A hollow steel pipe 9 is inserted outside the secondary rib round steel bars 8, and a firm and reliable rolling mechanism can be formed. Generally speaking, the width of the hollow steel pipe 9 is greater than the width of the cabinet to place the cabinet completely on the hollow steel pipe.

[0031] The extension bracket 2 is provided to facilitate the operation on the other side of the window wall. Taking the relocation of a new cabinet as an example, after the cabinet has been transported from one side of the base frame 1 to the interior of the room, the extension bracket 2 completes the transportation and stable unloading inside the room. As Figure 2 shown, the extension bracket 2 is hinged at the overlapping end 3 of the base frame. The extension bracket 2 has a second support end 10 away from the overlapping end 3 of the base frame, and a height-adjustable second support leg 11 is connected to the second support end 10.

[0032] The structural design of the second support leg 11 is the same as that of the first support leg 5. Considering that the height of the indoor ground may be higher than that of the outdoor ground, the height of the second support leg 11 can be different from that of the first support leg 5. The purpose of adjusting the height of the second support leg 11 is also to enable the extension bracket 2 to assume two postures, namely the horizontal position and the inclined position, so as to realize the indoor-side transportation and unloading of the cabinet respectively.

[0033] Specifically, the second support leg 11 includes a second short pipe 110 at the bottom of the second support end 10, and also includes a second support rod 111 and a second base 112 connected to the bottom of the second support rod 111; inserting the second support rod 111 into the second short pipe 110 can adjust the extension bracket 2 to the horizontal position, and pulling the second support rod 111 out of the second short pipe 110 can adjust the extension bracket 2 to the inclined position.

[0034] The design of the rolling mechanism on the extension bracket 2 is the same as that of the base frame. The extension bracket 2 also includes two main square steel bars 7 arranged in parallel left and right, and the main square steel bars 7 of the extension bracket 2 are hinged to the outside of the corresponding main square steel bars 7 of the base frame 1 through double-headed bolts 12. Due to the difference in indoor and outdoor spaces, the number of secondary square steel bars 8 on the base frame 1 is 7 (the number of corresponding hollow steel pipes 9 is also 7), and the number of secondary square steel bars 8 on the extension bracket 2 is 5 (the number of corresponding hollow steel pipes 9 is also 5).

[0035] The working process of the present utility model is as follows: After the machine room window is opened, the overlapping end 3 of the base frame 1 overlaps on the window sill. Lower the height of the first support leg 5 of the base frame 1, and the base frame 1 is in the inclined position. Slowly place the cabinet obliquely on the hollow steel pipe row of the base frame 1. After lifting the cabinet and the base frame 1 off the ground to the horizontal, raise the height of the first support leg 5 of the base frame 1 to keep the base frame 1 in the horizontal position, and push the cabinet to slide on the hollow steel pipe row through the window sill into the indoor side; at this time, adjust the extension bracket 2 to the horizontal position, continue to push the cabinet until the cabinet basically enters the room, lower the height of the second support leg 11 of the extension bracket 2, and the extension bracket 2 is in the inclined position to make the cabinet stand upright slowly. To transfer the cabinet out of the room, just operate in reverse according to the above steps. After use, the cabinet relocation tool can be folded left and right through the double-headed bolts 12, which is convenient for tool carrying.

[0036] At present, the cabinet relocation tool of this embodiment has been applied to the shutdown maintenance and technical transformation construction of Puguang Gas Field, successfully realizing the safe and non-destructive relocation and transfer of all SIS cabinets in valve chambers and gas gathering stations. The damage rate of equipment and instruments is 0. At the same time, the relocation and transfer were completed 5 days ahead of the original plan, reducing the man-hours by more than 125 person-days and saving the labor cost by more than 40,000 yuan, laying a solid foundation for the early completion of the technical transformation of the gathering and transportation SIS system and reducing the production time loss of the daily natural gas production of 24.5 million cubic meters in the gas field.

[0037] Embodiment 2

[0038] The cabinet relocation tool of this embodiment, as Figure 3 shown, includes a base frame 1. The base frame 1 has a lapping end 3 for lapping with the window wall and a first supporting end 4 for supporting on the ground outside or inside the window. A first support leg 5 with adjustable height is connected to the first supporting end 4. The structures of the first support leg 5 and the rolling mechanism on the base frame 1 are the same as those in Embodiment 1 and will not be described in detail here.

[0039] A stop member 6 for restricting the relative movement of the base frame 1 with respect to the window wall during the movement of the cabinet is provided at the lapping end 3 of the base frame 1. The stop member 6 can be provided on one or both sides of the window sill. For example, when relocating the cabinet from the outside to the inside, the stop member can be provided corresponding to the outer side of the window sill wall. During the process of pushing the cabinet from the outside to the inside, the outer stop member can play a stopping role. When relocating the cabinet from the inside to the outside, the setting of the single-sided stop member is similar.

[0040] In order to achieve a more firm fixation of the base frame to the wall, an outer stop member and an inner stop member corresponding to the outer side and the inner side of the window sill wall can be provided on the base frame 1 respectively. At the same time, there can be more than one outer stop member and inner stop member. For example, there are two outer stop members and two inner stop members, and they are symmetrically arranged on both sides in the width direction of the base frame. There are no special requirements for the forms of the outer stop member and the inner stop member. For example, they can be hemispherical protrusions, blocks, etc.

[0041] In order to adapt to the stop requirements of different walls and increase the adaptability of the cabinet relocation tool to different relocation environments, Figure 3 the stop member 6 adopts the form of a limit rod. Two front limit rods and two rear limit rods are symmetrically arranged on both sides in the width direction of the base frame. Four bolts are welded to the lapping end 3 of the base frame 1, and the four limit rods are fixedly connected to the main rib round steel 7 through nuts. The advantage of this design is that the connection method between the nut and the limit rod is flexible. The nut can be tightened after the base frame is adjusted to the horizontal position to achieve a firm fixation of the base frame to the wall; when the attitude of the base frame needs to be adjusted, the nut is loosened to avoid interference between the limit rod and the window sill wall.

[0042] When the utility model is in operation, first place the lapping end 3 of the base frame 1 on the window sill wall. The front limit rod and the rear limit rod are respectively located on both sides of the wall. After the cabinet is placed, lift the cabinet together with the base frame 1 off the ground to the horizontal. The first support foot 5 of the base frame 1 supports the first support end 4 of the base frame 1 to keep the base frame 1 horizontal. Tighten the nuts at the limit rods to firmly fix the base frame 1 on the window sill wall. Push the cabinet to slide on the hollow steel pipe row through the window sill and into the indoor side. At this time, on the indoor side, the cabinet can be caught by manual or other loading tools and the cabinet can be slowly erected.
