Description

Technical Field

[0001] The invention relates to the technical field of electric cabinets for urban rail transit vehicles, and in particular to a chassis auxiliary installation structure in an electric cabinet structure for urban rail transit vehicles. Background Art

[0002] There are many electrical cabinets in the entire operation system of urban rail transit. The common structure of electrical cabinets is as follows: Figure 4-Figure 6 As shown: it includes four vertical mounting columns (a), the top of the mounting column (a) is provided with a top plate (b) for covering, the bottom of the mounting column (a) is provided with a bottom plate (c), and multiple chassis (d) are installed between the four mounting columns (a) from top to bottom. The structure of the chassis (d) is a cubic rectangular structure, and a mounting plate (e) is provided on both sides of one side of the chassis (d), and a first connecting hole (f) is opened on the mounting plate (e). At the same time, first threaded holes (g) are also opened on two adjacent mounting columns (a). The operation of installing the chassis (d) on the electrical cabinet is to respectively correspond the first connecting holes (f) on both sides of the chassis (d) to the first threaded holes (g) on ​​the two mounting columns (a), and then use bolts to penetrate the first connecting holes (f) and threadedly connect them in the first threaded holes (g). At this time, the chassis (d) can be installed between the four mounting columns (a).

[0003] The above-mentioned electrical cabinet can only install a chassis (d) of a given specification. When the model of the chassis (d) changes, the size of the mounting plate (e) on the chassis (d) will also change accordingly, so that the mounting plate (e) cannot be installed on the mounting column (a) by bolts. Therefore, it cannot be adapted to the installation of chassis (d) within a certain size range. Therefore, people will use some auxiliary connection structures to install chassis (d) within a certain size range. This auxiliary connection structure acts as an intermediate bridge, one side of which is connected to the mounting column (a) and the other side is fixedly connected to the mounting plate (e). People often use a threaded connection method to fix the auxiliary connection structure to the mounting plate (e). The specific method is to open a threaded hole on the auxiliary connection structure and connect the threaded hole to the mounting column (a). The first connecting hole (f) on the plate (e) corresponds to the first connecting hole (f), and then a bolt is first passed through the first connecting hole (f), and then the bolt is rotated to allow the bolt to pass through the threaded hole. In order to ensure the firmness of the bolt connection and prevent the bolt from falling off, the installer will also use a nut and then rotate it on the bolt, so that the mounting plate (e) and the auxiliary connecting structure are clamped and fixed in the middle by the bolt cap and nut of the bolt, thereby completely achieving a firm connection. The installer frequently turns the bolt and frequently rotates the nut on the bolt, because multiple chassis (d) are often installed on an electrical cabinet, so the installer will frequently tighten the bolts and nuts, which will cause sore fingers to the installer, and this connection method consumes a long time, which is not conducive to the installation of the electrical cabinet structure. Summary of the invention

[0004] The purpose of the present invention is to address the deficiencies in the prior art and to introduce an auxiliary installation structure for an electrical cabinet chassis of an urban rail transit vehicle, which is used to solve the technical problem mentioned in the background technology that when an auxiliary connecting structure is used to install the chassis, the auxiliary connecting structure and the mounting plate are mostly installed with bolts and nuts, which causes the installers to frequently tighten the bolts and nuts, thereby causing soreness and discomfort in the installers' fingers.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] The auxiliary mounting structure of an electrical cabinet chassis of an urban rail transit vehicle includes a connecting plate for mounting a mounting plate on a mounting column, a penetration rod, a first clamping plate, a second clamping plate and a clamping drive mechanism, wherein the connecting plate is respectively provided with a second connecting hole corresponding to the first connecting hole and a second threaded hole corresponding to the first threaded hole, the first threaded hole and the second threaded hole are connected by a screw to fix the connecting plate and the mounting column, the penetration rod penetrates through the corresponding first connecting hole and the second connecting hole and can slide back and forth along the penetration direction, the first clamping plate is detachably clamped and fixed to one end of the penetration rod, the second clamping plate is penetrated on the penetration rod from the other end of the penetration rod, and the second clamping plate can slide back and forth along the axis of the penetration rod, the clamping drive mechanism is arranged on the penetration rod and the clamping drive mechanism is connected to a side of the second clamping plate close to the first clamping plate, so as to drive the second clamping plate to move in the direction of the first clamping plate and clamp the connecting plate and the mounting plate between the first clamping plate and the second clamping plate.

[0007] Working principle: According to the size of the chassis to be installed, two connecting plates are selected, and the two connecting plates are symmetrically arranged on both sides of the chassis, and the two connecting plates form a one-to-one correspondence with the two mounting plates on the chassis. The connecting plates here belong to the auxiliary connecting structure mentioned in the background technology. The second connecting hole is adaptively opened on each connecting plate, and a second threaded hole is opened on the connecting plate, so that during the installation of the chassis, the two connecting plates respectively correspond to the two mounting plates, and ensure that the second connecting hole on each side can correspond to the first connecting hole on that side, and ensure that the second threaded hole on each side can correspond to the first threaded hole on that side, and then the bolts are threadedly connected in the corresponding first threaded hole and the second threaded hole, and then the penetration rod is penetrated through the corresponding first connection hole and the second connection hole, and then the first clamping plate is clamped and installed on one end of the penetration rod, and finally the clamping drive mechanism is used to drive the second clamping plate to move in the direction of the first clamping plate until the mounting plate and the connecting plate are clamped and fixed between the first clamping plate and the second clamping plate.

[0008] The beneficial effects of the present invention are:

[0009] The present invention uses the auxiliary installation structure of the connecting plate, and when installing chassis of different specifications, it only needs to open a second connecting hole corresponding to the first connecting hole on the mounting plate on the connecting plate, and open a second threaded hole corresponding to the first threaded hole on the connecting plate. This method can realize the installation of chassis within a certain size range, which greatly improves the applicability of the present invention. In addition, the setting of the through rod and the clamping drive mechanism changes the traditional way of thinking of using bolts to fix the mounting plate and the connecting plate together. This method can effectively replace the bolt connection method, thereby effectively alleviating the phenomenon of finger pain of the installer. Compared with the bolt connection method, this method can connect the connecting plate and the mounting plate together more quickly, effectively improving the installation efficiency.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1-Figure 3As shown, the auxiliary installation structure of the electrical cabinet of the urban rail transit vehicle includes a connecting plate 1 for installing the mounting plate e on the mounting column a, a penetration rod 2, a first clamping plate 3, a second clamping plate 4 and a clamping drive mechanism, the connecting plate 1 is respectively provided with a second connecting hole 5 corresponding to the first connecting hole f and a second threaded hole 6 corresponding to the first threaded hole g, the first threaded hole g and the second threaded hole 6 are connected by a screw to fix the connecting plate 1 and the mounting column e, the connecting plate 1 is a bent plate-like structure, the penetration rod 2 is penetrated through the corresponding first connecting hole f The first clamping plate 3 is detachably fixed to one end of the penetration rod 2 by snapping and clamping, the second clamping plate 4 is penetrated on the penetration rod 2 from the other end of the penetration rod 2, and the second clamping plate 4 can slide back and forth along the axis of the penetration rod 2, the clamping drive mechanism is arranged on the penetration rod 2 and the clamping drive mechanism is connected to the side of the second clamping plate 4 close to the first clamping plate 3, so as to drive the second clamping plate 4 to move in the direction of the first clamping plate 3 and clamp the connecting plate 1 and the mounting plate e between the first clamping plate 3 and the second clamping plate 4. With the help of the connecting plate 1, the second connecting hole 5 and the second threaded hole 6, when the size of the chassis d changes within a certain range, the installer can open the second connecting hole 5 corresponding to the first connecting hole f on the mounting plate e on the connecting plate 1 as needed, so that the chassis d within a certain size range can be installed, which greatly improves the scope of application of the present invention.

[0020] The clamping drive mechanism includes a pulling rod 7 coaxially inserted into the penetration rod 2 from one end of the penetration rod 2 away from the first clamping plate 3, a connecting component and a locking component. The pulling rod 7 can slide back and forth along the penetration direction and the end of the pulling rod 7 away from the first clamping plate 3 extends out of the penetration rod 2. The connecting component is arranged on the penetration rod 2 and is located between the first clamping plate 3 and the second clamping plate 4. The connecting component is connected to the side of the second clamping plate 4 close to the first clamping plate 3, so as to drive the second clamping plate 4 to move in the direction of the first clamping plate 3 as the pulling rod 7 is pulled. The locking component is arranged at the end of the penetration rod 2 away from the first clamping plate 3, so as to be used for relative locking between the pulling rod 7 and the penetration rod 2.

[0021] The connecting component includes at least one channel 8 and at least one pulling rope 9, the channel 8 is opened on the penetration rod 2 and is located between the first clamping plate 3 and the second clamping plate 4, the two ends of the pulling rope 9 are respectively connected to the side of the second clamping plate 4 close to the first clamping plate 3 and the end of the pulling rod 7 close to the first clamping plate 3, and the pulling rope 9 passes through the channel 8 along the channel 8 to drive the second clamping plate 4 to move in the direction of the first clamping plate 3 as the pulling rod 7 moves, and then drives the pulling rope 9 to move through the pulling rod 7, and then drives the second clamping plate 4 to move toward the first clamping plate 3. At the same time, due to the overall trend of moving in the pulling direction of the pulling rod 7, the penetration rod 2 is driven to move along the pulling direction, and then the penetration rod 2 drives the first clamping plate 3 to move toward the second clamping plate 4. This process realizes the relative movement between the first clamping plate 3 and the second clamping plate 4, so that the connecting plate 1 and the mounting plate e can be fixedly connected together more quickly, which can improve the installation efficiency. There are two channels 8 and the two channels 8 are symmetrically formed with the axis of the penetration rod 2 as the center, and there are two pulling ropes 9 and the two pulling ropes 9 are respectively penetrated in the two channels 8 and are symmetrically formed with the axis of the penetration rod 2 as the center. In this way, when the pulling rod 7 moves, the pulling rod 7 can pull the second clamping plate 4 more evenly through the two pulling ropes 9, thereby better ensuring that the second clamping plate 4 slides along the penetration rod 2, thereby further improving the installation efficiency.

[0022] The locking assembly includes a mounting block 10 and a plug-in rod 11. The mounting block 10 is fixed to the end of the penetration rod 2 away from the first clamping plate 3. The plug-in rod 11 radially penetrates the mounting block 10 along the penetration rod 2, and the plug-in rod 11 can slide along the penetration direction and be locked by the static friction between the mounting block 10 and the plug-in rod 11. A row of evenly distributed plug-in grooves 12 are opened along the axis of the pull-out rod 7, and the plug-in rod 11 can be plugged into the plug-in groove 12. This method has a simple structure and can save production costs to a great extent.

[0023] The first clamping plate 3 is provided with a cavity 13, and the first clamping plate 3 is provided with a card interface 16 for connecting the cavity 13 with the outside. A cylindrical block 17 is fixed to the end of the penetration rod 2 connected to the first clamping plate 3, and a card block 14 whose shape is adapted to the card interface 16 is fixedly connected to the end of the cylindrical block 17. During installation, the card block 14 is aligned with the card interface 16 and the card block 14 is sent into the cavity 13. At this time, the cylindrical block 17 is located in the card interface 16. Then, the first clamping plate 3 is rotated, so that the card block 14 is offset from the position of the card interface 16. At this time, the card block 14 can be limited in the cavity 13. This method has a fast speed for detachable installation of the first clamping plate 3, which is conducive to improving the installation efficiency of fixing the connecting plate 1 and the mounting plate e together.

[0024] The connecting plate 1 is fixedly connected with a support plate 15 for supporting the chassis d, and the support plate 15 can further support the chassis d, thereby ensuring the firmness of the installation of the chassis d. The connecting plate 1 and the support plate 15 fixed on the connecting plate 1 are integrally formed, and this method ensures the structural strength of the connecting plate 1 and the support plate 15 as a whole, and further ensures the installation quality of the chassis d.

[0025] Working principle: Figure 1 , Figure 2 and Figure 7 As shown, according to the size of the chassis d to be installed, two connecting plates 1 are selected, and the second connecting hole 5 is adaptively opened on each connecting plate 1, and a second threaded hole 6 is opened on the connecting plate 1, so that during the installation of the chassis d, the two connecting plates 1 respectively correspond to the two mounting plates e, and ensure that the second connecting hole 5 on each side can correspond to the first connecting hole f on that side, and ensure that the second threaded hole 6 on each side can correspond to the first threaded hole g on that side, and then bolts are threadedly connected in the corresponding first threaded hole g and second threaded hole 6, and then the penetration rod 2 is penetrated through the corresponding first connection hole f and second connection hole 5, and then the first clamping plate 3 is clamped It is installed at one end of the penetration rod 2. The specific method is to send the clamping block 14 into the cavity 13 through the clamping interface 16, then rotate the first clamping plate 3, and then pull the pulling rod 7. The pulling rod 7 will drive the pulling rope 9 to move during the movement, so that the pulling rope 9 drives the second clamping plate 4 to approach the first clamping plate 3, and the first clamping plate 3 also approaches the second clamping plate 4. With the continuous pulling of the pulling rod 7, the first clamping plate 3 and the second clamping plate 4 will eventually clamp the connecting plate 1 and the mounting plate e firmly in the middle, and then push the plug-in rod 11, so that the plug-in rod 11 is plugged into the corresponding plug-in groove 12 at this time, that is, the relative locking between the penetration rod 2 and the pulling rod 7 is completed, and the entire installation process is completed.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
