Description

Technical Field

[0001] The present invention relates to a transformer substation installation technology, and more particularly to a steel structure assembled transformer substation auxiliary installation trolley. Background Art

[0002] In recent years, with the rapid development of the regional economy, the requirements for power grid construction have been continuously improved, and the number of steel structure assembled substation construction projects has increased sharply. The contradictions such as short construction period, heavy tasks, and insufficient staffing have become increasingly prominent. The problems existing in the construction process of steel structure assembled substations have become more and more serious. The fasteners used for fixing during the assembly of the substation are all metal parts, and these metal parts have no protection measures. If they are not careful, they will fall from above, which may cause harm to the construction workers below. In serious cases, casualties will occur, greatly delaying the progress of the project. Summary of the Invention

[0003] In order to overcome the above-mentioned shortcomings, the present invention provides a steel structure assembled substation auxiliary installation trolley, which facilitates the placement of fasteners during the substation assembly process and prevents fasteners from falling and causing safety hazards.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a steel structure assembled substation auxiliary installation trolley, comprising a vehicle body movably mounted on the substation assembly beam, wheels mounted on the bottom of the vehicle body, the wheels supported on the assembly beam, a storage cavity provided on the vehicle body, rotatable positioning arms mounted on both sides of the lower left and right sides of the vehicle body, positioning guide wheels mounted on the ends of the positioning arms, the two positioning arms rotate toward the installation beam so that the two positioning guide wheels lean against the left and right sides of the installation beam.

[0005] During the assembly operation of the steel structure prefabricated substation, the fasteners are loaded into the storage cavity on the vehicle body, and the vehicle body is installed on the assembly beam. During the connection and tightening process of the assembly beam, the fasteners in the storage cavity are taken out for connection, and the retrieval operation is convenient. The wheel support on the assembly beam realizes the stable support of the vehicle body, and the positioning guide wheels on the two positioning arms are respectively against the left and right sides of the assembly beam to prevent the vehicle body from swaying and tipping over, thereby ensuring the stability of the vehicle body. The use of wheels for support facilitates the movement of the vehicle body and the access to the fasteners in the vehicle body. After the installation of the steel structure prefabricated substation is completed, the two positioning arms are rotated away from the assembly beam, and then the entire vehicle body is hoisted to the ground. The auxiliary installation trolley for the steel structure prefabricated substation of this patent application facilitates the placement of fasteners during the assembly process of the substation and prevents fasteners from falling and causing safety hazards.

[0006] Preferably, the assembly beam is an I-beam, which includes an upper beam plate, a lower beam plate, and an intermediate beam plate. The intermediate beam plate is vertically connected between the upper beam plate and the lower beam plate. The wheels are supported on the upper beam plate, and the positioning guide wheels rest on the intermediate beam plate.

[0007] The wheels are supported on the upper beam plate, and the positioning guide wheels are supported on the middle beam plate, ensuring the stability of the entire vehicle body.

[0008] Preferably, the lower end of the vehicle body is fastened to a magnetic block for attracting the assembly beam.

[0009] The magnetic blocks are installed on the vehicle body, thereby increasing the friction between the wheels and the assembly beam. The vehicle body installed on the assembly beam is not easy to move independently, ensuring the stability of the vehicle body.

[0010] Preferably, the vehicle body includes a frame and a cargo basket mounted on the frame, the internal cavity of the cargo basket forms a storage cavity, and downwardly extending connectors are provided on the left and right sides of the frame, and the positioning arms are connected to the connectors.

[0011] The downward-extending connector facilitates the connection of the positioning arm. The cargo basket is mounted on the frame for stability and reliability.

[0012] Preferably, a storage rack is installed in the storage cavity. The arrangement of the storage rack facilitates the placement of the fasteners.

[0013] Preferably, a connecting ring is provided on the positioning arm, and connecting pins are provided on the vehicle body and corresponding to the connecting ring. The connecting ring and the connecting pin are movably connected to realize the rotation of the positioning arm. A positioning screw is connected to the connecting ring, and a positioning hole is provided on the vehicle body. After the positioning arm is rotated into place, the positioning screw is connected to the corresponding positioning hole.

[0014] The positioning arm rotates upward or downward to make the positioning guide wheel lean against the assembly beam, and the connection rotates around the connecting pin. After rotating into place, the positioning screw is connected with the positioning hole on the vehicle body to lock the positioning arm.

[0015] Preferably, the positioning guide wheel is a universal ball wheel.

[0016] The universal ball wheel can rotate in all directions and is flexible in guidance without getting stuck.

[0017] Another solution is that a lower connecting plate is provided on the positioning arm, and an upper connecting plate is provided on the vehicle body. The upper connecting plate and the lower connecting plate are arranged correspondingly. A connecting column is provided on the lower connecting plate, and a connecting hole is provided on the upper connecting plate. The connecting column is plug-connected with the connecting hole, and a positioning nut is threadedly connected to the connecting column, and the positioning nut is supported on the upper connecting plate.

[0018] This connection method enables the lateral rotation of the positioning arm, which moves toward the assembly beam so that the positioning guide wheel rests on the assembly beam. During the rotation of the positioning arm, the connecting column rotates in the connecting hole, and the rotation of the positioning nut can adjust the vertical position of the positioning arm.

[0019] Preferably, the connecting column is arranged vertically, an L-shaped clamp is provided on the positioning arm, a clamping groove is formed between the clamp and the positioning arm, the edge of the assembly beam is placed in the clamping groove, a locking screw is connected to the positioning arm, and the end of the locking screw abuts against the assembly beam to achieve clamping positioning, and a gap is provided between the upper connecting plate and the lower connecting plate.

[0020] After the positioning arm is rotated into position, the clamping groove is clamped together with the edge of the assembly beam, and then the locking screw is rotated, and the end of the locking screw abuts against the assembly beam to achieve clamping and positioning, so that the clamping plate and the assembly beam are tightly connected together. Before the assembly beam is hoisted, the car body is installed on the assembly beam, and the car body and the assembly beam are hoisted together to reduce the hoisting cost. Since the clamping plate and the assembly beam are tightly connected together, the car body will not move automatically during the hoisting process, ensuring the stability of the hoisting. There is a gap between the upper connecting plate and the lower connecting plate. In the process of rotating the locking screw to clamp the clamping plate and the assembly beam, there is a certain amount of movement space between the positioning arm and the car body, avoiding interference and jamming. After the car body and the assembly beam are hoisted into place, the locking screw is loosened so that the car body can be pushed, making it more flexible to use.

[0021] Preferably, the upper connecting plate is threaded with an anti-rotation screw, and the lower connecting plate is provided with an anti-rotation hole. After the positioning arm is rotated toward the assembly beam, the lower end of the anti-rotation screw is inserted into the anti-rotation hole.

[0022] After the positioning arm is rotated into place, the lower end of the anti-rotation screw is inserted into the anti-rotation hole to achieve reliable positioning of the positioning arm and prevent the positioning arm from rotating any further.

[0023] Compared with the prior art, the beneficial effects of the present invention are: (1) the auxiliary installation trolley for steel structure assembled substations of the present patent application facilitates the placement of fasteners during the assembly process of the substation, and prevents fasteners from falling and causing safety hazards; (2) the trolley body can be hoisted together with the assembly beam, which is conducive to reducing the hoisting cost; the trolley body and the assembly beam will not slide during the hoisting process, and the hoisting is stable and reliable; (3) the trolley body has a certain resistance when installed on the assembly beam, which plays a positioning role and prevents the free movement of the trolley body from affecting normal assembly.

DETAILED DESCRIPTION

[0027] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0028] Example 1: A steel structure assembled substation auxiliary installation trolley (see attached Figure 1 ), comprising a vehicle body 2 movably mounted on a substation assembly beam 1, with wheels 3 mounted on the bottom of the vehicle body, supported by the assembly beam. Two wheels are provided at the front and rear of the vehicle body, and these four wheels provide stable and reliable support for the vehicle body. The vehicle body is provided with a storage cavity, within which a storage rack 4 is mounted, for storing fasteners. Rotatable positioning arms 5 are mounted on the left and right sides of the lower portion of the vehicle body, with positioning guide wheels 6 mounted on their ends. The two positioning arms rotate toward the mounting beam, causing the two positioning guide wheels to rest against the left and right sides of the mounting beam.

[0029] The assembly beam is an I-beam and includes an upper beam plate 7, a lower beam plate 8, and an intermediate beam plate 9. The intermediate beam plate is vertically connected between the upper and lower beam plates. The wheels are supported on the upper beam plate, and the positioning guide wheels rest on the intermediate beam plate. The vehicle body includes a frame 10 and a cargo basket 11 mounted on the frame. The internal cavity of the cargo basket forms a storage cavity. The left and right sides of the frame are provided with downwardly extending connectors 12, and positioning arms are connected to the connectors. The upper beam plate is placed between the frame and the positioning arms. The positioning arms and the connectors are connected to form a U-shaped structure. The lower end of the vehicle body is fastened to a magnetic block 13 for mutual attraction with the assembly beam, and a gap is provided between the magnetic block and the upper beam plate.

[0030] The positioning arm is equipped with a connecting ring 14, and a connecting pin 15 is provided on the vehicle body corresponding to the connecting ring. The connecting ring and the connecting pin are movably connected to achieve the rotation of the positioning arm. The axes of the connecting ring and the connecting pin are arranged horizontally. The connecting ring is connected to a positioning screw 16, and a positioning hole is provided on the vehicle body. After the positioning arm is rotated into place, the positioning screw is connected to the corresponding positioning hole. The positioning guide wheel is a universal ball wheel, and a gap is provided between the positioning arm and the lower surface of the upper beam plate.

[0031] During the assembly operation of the steel structure prefabricated substation, the fasteners are loaded into the storage cavity on the vehicle body, and the vehicle body is installed on the assembly beam. During the connection and tightening process of the assembly beam, the fasteners in the storage cavity are taken out for connection, and the retrieval operation is convenient. The wheel support on the assembly beam realizes the stable support of the vehicle body, and the positioning guide wheels on the two positioning arms are respectively against the left and right sides of the assembly beam to prevent the vehicle body from swaying and tipping over, thereby ensuring the stability of the vehicle body. The use of wheels for support facilitates the movement of the vehicle body and the access to the fasteners in the vehicle body. After the installation of the steel structure prefabricated substation is completed, the two positioning arms are rotated away from the assembly beam, and then the entire vehicle body is hoisted to the ground. The auxiliary installation trolley for the steel structure prefabricated substation of this patent application facilitates the placement of fasteners during the assembly process of the substation and prevents fasteners from falling and causing safety hazards.

[0032] Example 2: A steel structure assembled substation auxiliary installation trolley (see attached Figure 2 ), its structure is similar to that of Example 1, the main difference being that in this embodiment, a lower connecting plate 17 is provided on the positioning arm, an upper connecting plate 18 is provided on the vehicle body, the upper connecting plate and the lower connecting plate are arranged correspondingly, a connecting column 19 is provided on the lower connecting plate, a connecting hole 20 is provided on the upper connecting plate, the connecting column is plug-connected to the connecting hole, a positioning nut 21 is threadedly connected to the connecting column, and the positioning nut is supported on the upper connecting plate. The connecting column is arranged vertically, an L-shaped clamping plate 22 is provided on the positioning arm, a clamping groove 23 is formed between the clamping plate and the positioning arm, an inclined guide surface 24 is provided on the upper edge of the clamping groove, the edge of the upper beam plate of the assembly beam is placed in the clamping groove, a locking screw 25 is connected to the positioning arm, the end of the locking screw abuts against the assembly beam to achieve clamping and positioning, and a gap is provided between the upper connecting plate and the lower connecting plate. An anti-rotation screw 26 is threadedly connected to the upper connecting plate, an anti-rotation hole 27 is provided on the lower connecting plate, the positioning arm rotates horizontally, and after the positioning arm rotates into position in the direction of the assembly beam, the lower end of the anti-rotation screw is plugged into the anti-rotation hole. The axis of the positioning guide wheel is arranged vertically. The other structures are the same as those in Example 1.

[0033] After the positioning arm is rotated into position, the clamping groove engages the edge of the assembly beam. The locking screw is then turned, causing the end of the locking screw to abut against the assembly beam, securing the clamp and securing the assembly beam. Before the assembly beam is hoisted, the vehicle body is mounted on the assembly beam and hoisted together, reducing lifting costs. Because the clamp and assembly beam are securely connected, the vehicle body does not move during the hoisting process, ensuring a smooth and stable hoisting. A gap is provided between the upper and lower connecting plates, allowing for sufficient movement between the positioning arm and the vehicle body during the process of tightening the clamp and assembly beam by turning the locking screw, preventing interference and jamming. After the vehicle body and assembly beam are hoisted into position, the locking screw is loosened, allowing the vehicle body to be pushed, providing greater flexibility. The positioning arm is subjected to gravity, and the clamp supports the upper beam plate, providing a certain degree of damping, preventing the vehicle body from moving easily. The gap between the upper and lower connecting plates can also be adjusted by turning the positioning screw, separating the clamp and the upper beam plate to reduce damping.

[0034] The above-described embodiments are only preferred solutions of the present invention and are not intended to limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solutions described in the claims.
