Description

Technical Field

[0001] This invention relates to the field of electrical component installation tooling technology for railway passenger vehicles, and in particular to a device for transmitting and installing components in a confined space. Background Technology

[0002] The reliable operation of the electrical system of rail vehicles is a necessary prerequisite for ensuring the safe and stable operation of rail vehicles. As the core connecting components of the rail vehicle's electrical system equipment, the installation quality of electrical system connectors plays a decisive role in the stability and safety of the electrical system equipment after installation, thus profoundly affecting the reliable operation of the electrical system and the vehicle's driving safety. To effectively ensure the installation quality of electrical system equipment, specialized equipment is required for precise operation during the transmission, positioning, and installation of electrical system connectors. This ensures that the components of the connectors are firmly and securely connected, comprehensively improving the installation quality, stability, and safety performance of the electrical system equipment. The existing operating methods for connectors are as follows:

[0003] First, place the connector to be installed at the entrance of the vehicle's enclosed, confined space. Then, outside the enclosed space, use the magnetic field generated by a strong magnetic material to transport the connector to the target installation position. Next, position the connector with the mounting hole in the enclosed space. Finally, use a wrench to tighten the connector and bolts together.

[0004] However, this operating method has many drawbacks. In a confined space, the transfer plane of the connector may have unevenness due to factors such as weld seams, which greatly hinders the effective transfer of the connector. Furthermore, this transfer method is only applicable to magnetizable connectors, limiting its applicability. Moreover, the poor directionality of the magnetic field forces necessitates repeated adjustments to the connector's installation positioning, resulting in extremely low work efficiency. Simultaneously, it is difficult to ensure the perpendicularity of the connector's threaded holes, which negatively impacts the installation quality of subsequent electrical system components. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects of the existing technology and provide a device for the transmission and installation of components in a closed and confined space that can transport connectors to the target installation position. This effectively solves the problem that the transmission plane of the connectors has a height difference due to factors such as welds, which hinders the effective transmission of the connectors.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This invention discloses a device for transmitting and installing components in a confined space, comprising:

[0008] A clamping mechanism, a limiting mechanism for fixed connection to the entrance of a confined space, the limiting mechanism having a transmission channel, and

[0009] A transmission mechanism capable of extending into confined spaces;

[0010] The clamping mechanism includes a first base with a cavity, one end of which has an opening for inserting the part to be installed. The first base has a rigid contact surface at the bottom of the cavity that is in rigid contact with the part to be installed, and an elastic contact surface at the top of the rigid contact surface that applies an elastic force toward the part to be installed, thereby cooperating with the rigid contact surface to hold the part to be installed.

[0011] The transmission mechanism includes several couplings connected end to end. Two adjacent couplings can be connected at any angle through a connecting structure and then rigidly connected in a straight line through the transmission channel. The first base is connected to the coupling at the first end so that it can be directionally delivered to the installation position through the transmission mechanism.

[0012] Furthermore, the connection structure includes limiting pins formed on both sides of one end of the coupling and limiting guide grooves opened at the other end of the coupling, as well as elastic members that elastically connect two adjacent couplings, wherein the couplings are slidably connected to the limiting guide grooves on the adjacent couplings through the limiting pins.

[0013] Furthermore, the coupling includes a first connecting section and a second connecting section with a width greater than that of the first connecting section. The second connecting section can be sleeved on the outside of the first connecting section. Limiting pins are fixedly connected to both sides of the first connecting section. Limiting guide grooves are formed on the inner walls of both sides of the second connecting section. The second connecting section is also provided with a connecting guide groove. The inner and outer surfaces of the top end of the first connecting section are both fixedly connected with hanging shafts that can hook the elastic element.

[0014] Furthermore, the last coupling of the transmission mechanism is connected to a second handle.

[0015] Furthermore, the first base is fixedly connected to a plurality of spring plates within the containing cavity, and the elastic contact surface is formed by the protruding outer surface of the spring plates.

[0016] Furthermore, a quadrilateral groove for forming the cavity is provided at one end of the first base, and a clearance groove communicating with the cavity is provided at the lower part of the first base. The side wall of the groove located on the clearance groove side is the rigid abutment surface. The side wall of the groove adjacent to the rigid abutment surface and the side wall opposite to the rigid abutment surface are both provided with guide grooves for installing the spring sheet.

[0017] Furthermore, one end of the spring sheet is fixedly connected to the guide groove, and the other end is a free end, which can slide along the guide groove.

[0018] Furthermore, a tailstock is formed on the outer side of the first base away from the containing cavity, which can be fitted onto the outside of the coupling. The sidewalls of the first base located on both sides of the clearance groove are rotatably connected to base wheels via axles.

[0019] Furthermore, the limiting mechanism includes a second base with the transmission channel at the top, the second base being rotatably connected to the bottom wall of the transmission channel and to the side wall with a side wheel;

[0020] The second base has a downwardly extending clamping arm section at its bottom, and a clamping groove with a side opening is formed on the side of the clamping arm section. The end of the clamping arm section is helically connected to a first handle, and the top of the first handle is connected to a top plate.

[0021] Furthermore, the second base is located at the bottom end of the clamping arm section and is fixedly connected to the laser ink line device by a mounting column.

[0022] In the above technical solution, the present invention provides a device for transmitting and installing components in a confined space, which has the following advantages:

[0023] Using this device for effective transmission, positioning, and installation of the parts to be installed, firstly, the clamping mechanism holds the parts to be installed with high stability, eliminating the need for repeated adjustments due to instability of the clamping mechanism during transmission or positioning. It also eliminates the drawback of needing to repeatedly adjust the installation and positioning of the connectors due to poor magnetic field directionality. At the same time, it ensures the perpendicularity of the threaded holes of the connectors, eliminating potential quality problems.

[0024] Secondly, by utilizing the transmission mechanism, the problem of uneven planes in the transmission plane of the connectors due to factors such as welds, which hinders the effective transmission of the connectors, is solved. It also avoids the drawback that the original operation and transmission method is only applicable to magnetizable connectors and has a relatively narrow range of applications.

[0025] In addition, the strong magnetic attraction operation method has been changed to a mechanical clamping and transmission operation method, which eliminates the damage to the components caused by sliding friction during the transmission process of the original installation method and eliminates potential quality problems.

[0026] After using this device, the assembly or disassembly of electrical system connector components is more than 30% more efficient than the original installation and operation methods for completing a single component. This not only improves construction quality and efficiency but also reduces the labor intensity of operators, material waste, and ensures product quality. Attached Figure Description

[0046] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0047] See Figure 1 , 3 As shown in Figure 6;

[0048] An invention relates to a device for transferring and installing components in a confined space, comprising: a clamping mechanism 1, a limiting mechanism 2, and a transmission mechanism 3;

[0049] The clamping mechanism 1 includes a first base 101, which has a cavity for holding a component to be installed. The component to be installed is a connector used in electrical systems in the prior art. One end of the cavity is open for inserting and removing the component to be installed. The first base 101 has a rigid contact surface 4 at the bottom of the cavity that is in rigid contact with the component to be installed. An elastic contact surface 5 is formed on the upper part of the first base 101 above the rigid contact surface 4 to apply an elastic force toward the rigid contact surface 4, so as to cooperate with the rigid contact surface 4 to hold the component to be installed.

[0050] The limiting mechanism 2 can be fixedly connected to the entrance of a closed and narrow space, and the limiting mechanism 2 has a transmission channel 6 that is slidably connected to the transmission mechanism 3 and guides its displacement.

[0051] The transmission mechanism 3 can extend into a narrow space. The transmission mechanism 3 includes several couplings 301 connected end to end. Two adjacent couplings 301 can be connected at any angle through the connection structure and then rigidly connected in a straight line through the transmission channel 6. The coupling 301 at the beginning is connected to the clamping mechanism 1. Preferably, the coupling 301 at the end is connected to a second handle 305 for hand gripping of the transmission mechanism 3.

[0052] During operation, the part to be installed is placed in the holding cavity of the first base 101 and is elastically held. The transmission mechanism 3 passes through the transmission channel 6 and connects to the first base 101. The limiting mechanism 2 is fixed at the entrance of the closed and narrow space. The angle of two adjacent couplings 301 of the transmission mechanism 3 is adjusted sequentially by external force. After the external force disappears, several couplings 301 are in the same straight line state, and the conveying clamping mechanism 1 reaches the installation position.

[0053] Reference Figure 2-5 As shown:

[0054] Preferably, the first base 101 is fixedly connected to a plurality of spring plates 102 within the holding cavity. The outer surface of the spring plate 102 forms an elastic abutment surface 5, which applies a clamping force to the part to be installed while ensuring that the part to be installed is located in the middle position of the holding cavity. In other words, the elastic abutment surface 5 and the rigid abutment surface 4 cooperate to elastically clamp the part to be installed, while ensuring that the part to be installed is centered.

[0055] For details, see Figure 3 As shown, a quadrilateral groove is provided at one end of the first base 101, forming a container cavity with one end open. A relief groove communicating with the container cavity is provided at the lower part of the first base 101. The side wall of the groove on the side of the relief groove is a rigid abutment surface 4. Guide grooves 106 are provided on the side walls of the groove adjacent to the rigid abutment surface 4 and the side walls opposite to the rigid abutment surface 4. The spring sheet 102 has an arc-shaped structure. One end of the spring sheet 102 is fixedly connected to the guide groove 106 by the first screw 103, and the other end is a free end. The free end abuts against the guide groove 106. When the convex arc surface of the spring sheet 102 is pressed, the free end of the spring sheet 102 can slide along the guide groove 106. Spring sheets 102 are installed on the three side walls of the groove of the first base 101. An elastic abutment surface 5 is formed by the convex arc surfaces of the three spring sheets 102. Of course, the elastic abutment surface 5 can also be a surface formed by other structures in the prior art, as long as it can ensure elastic grip on the part to be installed and ensure its centering.

[0056] The outer side of the first base 101 away from the containing cavity has a tailstock that can be fitted onto the outside of the coupling 301. The tailstock is connected to the coupling 301. The side walls on both sides of the clearance groove of the outer side of the first base 101 are fixedly connected to axles. The axles are mounted with base wheels 104 by second screws 105. The first base 101 uses the base wheels 104 to roll in contact with the narrow space to reduce transmission friction.

[0057] See Figure 10 , 11 As shown:

[0058] Preferably, the connection structure includes limiting pins 306 formed on both sides of one end of the coupling 301 and limiting guide grooves 308 opened at the other end of the coupling 301, as well as elastic members that elastically connect two adjacent couplings 301, wherein the coupling 301 is rigidly connected to the limiting guide grooves 308 on the adjacent coupling 301 through the limiting pins 306.

[0059] In this structure, the elastic element is a tension spring 304. The two adjacent couplings 301 of the transmission mechanism 3 are first connected at any angle by the tension spring 304 under the action of external force. Thus, the transmission mechanism 3 can change the angle in a narrow space without disconnecting the connection, so that its length is not limited and the flexibility of use is improved. When the external force is lost, the two adjacent couplings 301 are tightened under the action of the tension spring 304. At the same time, the couplings 301 are slidably connected to the limiting guide grooves 308 on the adjacent couplings 301 through the limiting pin 306, so as to realize the rigid linear directional transmission of the clamping mechanism 1.

[0060] See Figure 11 As shown:

[0061] Preferably, the coupling 301 includes a first connecting section and a second connecting section with a width greater than that of the first connecting section. The second connecting section can be sleeved on the outside of the first connecting section. Limiting pins 306 are fixedly connected to both sides of the first connecting section. Limiting guide grooves 308 are opened on the inner walls of both sides of the second connecting section, and the second connecting section is also provided with a connecting guide groove 309. The coupling 302 is fixedly connected to both sides of the first connecting section by a fourth screw. The connecting shaft 302 is slidably connected to the connecting guide groove 309 of the adjacent second connecting section. The top inner and outer surfaces of the first connecting section are both fixedly connected with hanging shafts 307 that can hook the tension spring 304.

[0062] Among them, the last coupling 301 of the transmission mechanism 3 is connected to the second handle 305. The two sides of the top of the second handle 305 are also fixedly connected to the limit pins 306. The two sides of the top of the second handle 305 are fixedly connected to the connecting shaft 302 by the fourth screw 303, which is used to slide with the connecting guide groove 309 of the second connecting section of the coupling 301. The outer wall of the top of the second handle 305 is fixedly connected to the hanging shaft 307, which is used to hook the elastic element, thereby connecting the adjacent coupling 301.

[0063] See Figure 11-13 As shown:

[0064] Specifically, during the assembly of the transmission mechanism 3, several couplings 301 are connected end to end to form a transmission chain. First, the limiting pin 306 at the front end of the second coupling 301 is inserted into the limiting guide groove 308 at the rear of the first coupling 301. Then, two connecting shafts 302 are respectively embedded into the connecting guide grooves 309 on both sides of the coupling 301, and the two connecting shafts 302 and the mounting holes at the front end of the second coupling 301 are adjusted to be coaxial. Two fourth screws 303 are used to install and fix the connecting shafts 302 to the front end of the adjacent couplings 301 respectively.

[0065] Next, one end of the tension spring 304 is installed on the hanging shaft 307 inside the previous coupling 301, and the other end of the tension spring 304 is installed on the hanging shaft 307 at the front end of the next coupling 301. The function of the tension spring 304 is to ensure that the two adjacent couplings 301 are on the same straight line when no external force is applied; or, when the adjacent couplings 301 are angled under the action of external force, after the external force disappears, due to the elastic force of the tension spring 304, they return to the same straight line state under the combined action of the limiting pin 306 on the outer side of the front end of the next coupling 301 and the limiting guide groove 308 on the inner side of the rear end of the previous coupling 301. This process is repeated to connect multiple couplings 301 to form a transmission chain.

[0066] Finally, insert the limiting pin 306 at the front end of the second handle 305 into the limiting guide groove 308 at the rear of the last coupling 301; then embed the two connecting shafts 302 into the connecting guide grooves 309 on both sides of the last coupling 301, and adjust the two connecting shafts 302 and the mounting holes at the front end of the last coupling 301 to be coaxial. Use two fourth screws 303 to install and fix the connecting shafts 302 to the front end of the second handle 305; install one end of the tension spring 304 onto the hanging shaft 307 inside the last coupling 301, and install the other end of the tension spring 304 onto the hanging shaft 307 at the front end of the second handle 305, completing the assembly of the transmission mechanism 3. The number of couplings can be appropriately increased or decreased according to the transmission distance of the parts to be installed to adapt to the transmission distance requirements.

[0067] To connect the clamping mechanism 1 and the transmission mechanism 3, the limiting pin 306 at the front end of the first coupling 301 of the transmission mechanism 3 is inserted into the limiting guide groove 308 in the tailstock at the rear of the first base 101. Then, the two connecting shafts 302 are respectively embedded into the connecting guide grooves 309 opened in the tailstock of the first base 101. The two connecting shafts 302 and the mounting holes at the front end of the first coupling 301 are adjusted to be coaxial. The connecting shafts 302 are respectively installed and fixed to the front end of the first coupling 301 with two fourth screws 303, thus completing the assembly of the clamping mechanism 1 and the transmission mechanism 3.

[0068] See Figure 6 As shown:

[0069] The limiting mechanism 2 includes a second base 201 with a transmission channel 6 at the top. The second base 201 is rotatably connected to the bottom wall of the transmission channel 6 and to the side wall with a side wheel 203. The bottom wheel 205 and the side wheel 203 make rolling contact with the bottom wall and side wall of the coupling 301.

[0070] The bottom of the second base 201 has a downwardly extending clamping arm section. The side of the clamping arm section forms a clamping groove with a side opening. The end of the clamping arm section is screwed and connected to a first handle 208. The first handle 208 is located at the end of the clamping groove and connected to a top plate 207. The top plate 207 and the side wall of the clamping groove are fixedly connected to the entrance of the closed and narrow space. Preferably, a laser ink line device 209 is fixedly connected to the bottom end of the clamping arm section.

[0071] See Figure 6-9 As shown:

[0072] When assembling the limiting mechanism 2, firstly, the four side wheels 203 are respectively installed on the first mounting shaft 204. Then, the four mounting holes of the first mounting shaft 204 with the side wheels 203 are respectively adjusted to be coaxial. The four first mounting shafts 204 are fastened to the second base 201 with four third screws 202 to limit the lateral displacement of the transmission mechanism 3 during the transmission process.

[0073] Next, the bottom wheel 205 is aligned with the bottom wheel mounting shaft hole on the second base 201. The bottom wheel 205 is then mounted onto the second base 201 using the second mounting shaft 206 through the bottom wheel mounting shaft hole on the second base 201. The bottom wheel 205 installation operation is repeated to install the other three bottom wheels 205 into place.

[0074] The first handle 208 is screwed into the screw hole of the clamping arm section of the second base 201, the top plate 207 is screwed onto the top of the first handle 208, and the laser ink line device 209 is installed onto the mounting post at the bottom of the clamping arm section of the second base 201. When the coupling 301 passes through the transmission channel 6 of the limiting mechanism 2, the side wheel 203 of the limiting mechanism 2 restricts the displacement of the coupling 301 in the left and right directions, and the second base 201 and the bottom wheel 205 restrict the displacement of the coupling 301 in the up and down directions. The structure of the side wheel 203 and the bottom wheel 205 changes the friction of the coupling 301 through the limiting mechanism 2 into rolling friction, reducing the resistance during the movement of the transmission mechanism 3.

[0075] In the above technical solution, the present invention provides a device for transmitting and installing components in a confined space, and the method of use is as follows:

[0076] The part to be installed is placed into the holding cavity of the first base 101 of the clamping mechanism 1. Under the elastic force of the three spring plates 102 on the first base 101, the part to be installed is fixed in the holding cavity of the first base 101 so as to facilitate the subsequent transfer and installation of components.

[0077] Place the clamping mechanism 1 and the limiting mechanism 2, which hold the component to be installed, into the entrance of the confined space in sequence. Turn on the laser ink line device 209 and adjust the position of the second base 201 of the limiting mechanism 2 so that the ink line emitted by the laser ink line device 209 coincides with the center of the mounting hole on the component mounting plane. Twist the first handle 208, and the first handle 208 drives the top plate 207 to fix the limiting mechanism 2 at the entrance of the confined space.

[0078] The angles of two adjacent couplings 301 of the transmission mechanism 3 are adjusted sequentially by external force. After the external force disappears, due to the elastic force of the tension spring 304, the limiting pin 306 on the outer side of the front end of the latter coupling 301 returns to the same straight line along the limiting guide groove 308 on the inner side of the rear end of the former coupling 301. This ensures that the coupling 301 and the clamping mechanism 1 are on the same plane. After the coupling 301 of the transmission mechanism 3 is limited by the limiting mechanism 2, it enters the closed and narrow space. The number of couplings 301 entering the closed and narrow space is determined according to the position and size of the part to be installed in the closed space. This allows the part to be installed to be transmitted to the position to be installed. The part to be installed is then pre-installed with bolts.

[0079] After the pre-installation of the installation components is completed, use external force to adjust the angles of the two adjacent couplings 301 of the transmission mechanism 3 outside the entrance of the confined space in sequence, and pull the transmission mechanism 3 and the clamping mechanism 1 out of the confined space. During the pulling process, the clamping mechanism 1 is separated from the installation components, and the installation components are tightened with tools.

[0080] When the coupling 301 connecting the transmission mechanism 3 and the clamping mechanism 1 comes into contact with the limiting mechanism 2, the laser ink line device 209 is turned off, the first handle 208 is released, and the limiting mechanism 2 and the clamping mechanism 1 are removed from the confined space to complete the installation operation.

[0081] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
