Description

Technical Field

[0001] The utility model relates to the technical field of rail vehicle assembly, in particular to a rail vehicle longitudinal beam installation and positioning auxiliary device. Background Art

[0002] The upper longitudinal beam of the subway vehicle is an important part of the vehicle interior frame, which plays a role in supporting and fixing the roof interior. First, the longitudinal beam is fixed on the C-shaped groove located above the roof and below the hanging wall. The roof interior components such as the side roof panels, lamps and diffusers are fastened to the roof frame through the longitudinal beam. In order to ensure the accuracy of the subsequent roof component equipment, the size of the longitudinal beam installation needs to be strictly controlled. According to the technical requirements for the installation of rail vehicle longitudinal beams, on the one hand, it is necessary to ensure that the longitudinal beam opening is 1409mm, and on the other hand, it is also necessary to ensure that the longitudinal beams on both sides are centered relative to the side walls of the vehicle body. This requires that the installation accuracy of the longitudinal beams be fully guaranteed during the installation process.

[0003] The existing installation and positioning method of the longitudinal beam is to use a tape measure to measure the gap between the longitudinal beams on both sides and the side wall of the vehicle body after the longitudinal beams are pre-installed on the hanging arm, and then calculate the distance that needs to be adjusted left and right. However, due to the high position of the longitudinal beam, it is inconvenient to use a tape measure to measure, and it is not easy to measure the gap between the longitudinal beam and the side wall; the tape measure has low measurement accuracy and the measurement results are not easy to read. In addition, since the longitudinal beam edge and the C-shaped groove of the side wall are not in the same plane, the tape measure reading is not accurate enough, and manual reading will also bring more errors. This makes the installation process of the longitudinal beam not only inefficient, but also difficult to ensure a high level of installation accuracy. Utility Model Content

[0031] The upper longitudinal beam of a subway vehicle is an important part of the interior installation skeleton of the vehicle, playing a role in supporting and fixing the interior installation of the roof. First, the longitudinal beam is fixed on the C-shaped groove located above the roof and below the hanging wall. Components such as side roof panels, lamps, and diffusers in the roof interior are fastened to the roof skeleton through the longitudinal beam. To ensure the accuracy of subsequent roof component installation, the installation dimensions of the longitudinal beam need to be strictly controlled. According to the technical requirements for the installation of the longitudinal beam of a rail vehicle, on the one hand, the opening between the longitudinal beams should be 1409 mm, and on the other hand, the two longitudinal beams should be centered relative to the side wall of the vehicle body. This requires fully ensuring the installation accuracy of the longitudinal beam during the installation process.

[0032] When installing the longitudinal beam, it is necessary to control the gap from both sides and also ensure the opening dimension between the two longitudinal beams. The existing installation and positioning method of the longitudinal beam is after the longitudinal beam is pre-installed on the hanging arm (such as Figure 1), first adjust the longitudinal beam opening, then adjust the gap on both sides. The process of adjusting the gap on both sides is to use a tape measure to measure the gap between the longitudinal beams on both sides and the side wall of the vehicle body, and then calculate the distance that needs to be adjusted left and right. However, due to the high position of the longitudinal beam, it is inconvenient to use a tape measure to measure, and it is not easy to measure the gap between the longitudinal beam and the side wall; at the same time, the measurement accuracy of the tape measure is low and the measurement result is not easy to read. In addition, since the longitudinal beam edge and the C-shaped groove of the side wall are not in the same plane, the tape measure reading is not accurate enough, and manual reading will also bring more errors. This makes the installation process of the longitudinal beam not only inefficient, but also difficult to ensure the installation accuracy at a high level.

[0033] See also Figures 2 - 4 The utility model is a rail vehicle longitudinal beam installation positioning auxiliary device, comprising a connecting rod 1, a clamp 2 and a measuring rod 4; the connecting rod 1 is used as a connecting structure between two clamps 2, and it can be a hollow square tube structure or a hollow tube structure of other shapes. Further, the connecting rod 1 can be set as a telescopic rod. So that the distance between the two clamps 2 can be adjusted.

[0034] See also Figures 2 - 4 In one embodiment of the utility model, the clamping head 2 is arranged at both ends of the connecting rod 1 and is fixedly connected to the connecting rod 1, and a clamping slot 3 is arranged on the clamping head 2, and the size of the clamping slot 3 is consistent with the size of the longitudinal beam; so that the clamping head 2 can be set on the longitudinal beam structure through the clamping slot 3 when in use. The clamping head 2 may include a main body, and a clamping block 1 and a clamping block 2 are fixedly arranged on the main body, and the clamping block 1 and the clamping block 2 are arranged opposite to each other and cooperate with the main body to enclose the clamping slot 3. Specifically, the clamping block 1 and the clamping block 2 can be respectively and integrally arranged at the two ends of the main body. Furthermore, the height dimension of the clamping block 1 is greater than the height dimension of the clamping block 2, and the clamping block 1 is on the outside. In this way, it is more convenient to clamp upward on the longitudinal beam.

[0035] See also Figures 2 - 4, in one embodiment of the present utility model, the measuring rod 4 is respectively slidably disposed at both ends of the connecting rod 1 and can linearly move along the length direction of the connecting rod 1. When the connecting rod 1 is of a hollow structure, the measuring rod 4 can be slidably disposed inside the measuring rod 4. Or other sliding connection methods can be adopted, such as a slide rail and slider structure. An indicating scale is provided on the measuring rod 4. Thus, when the measuring rod 4 extends out of the connecting rod 1, the position data or displacement data of the measuring rod 4 can be obtained through the scale. Further, a digital display dial 6 for displaying the moving distance of the measuring rod 4 can be provided on the connecting rod 1, and the display dial cooperates with the measuring rod 4 to form a structure similar to an existing digital display vernier caliper. The displacement amount of the measuring rod 4 is directly displayed through the digital display dial 6, avoiding errors caused by manual reading. A positioning head 5 can be fixedly provided at one end of the measuring rod 4 away from the connecting rod 1. The positioning head 5 can be integrally provided on the side surface of the measuring rod 4. By providing the positioning head 5, the measuring rod 4 can better contact the corresponding position of the vehicle body side wall when it extends out.

[0036] Please refer to Figures 2 - 4 , in one embodiment of the present utility model, a clamping plate 8 can be provided in the clamping groove 3. One clamping plate 8 can be provided, which is disposed close to one of the clamping blocks, or two clamping plates 8 can be provided, corresponding to the two clamping blocks respectively. A locking structure is connected to the clamping plate 8, and the locking structure is used to drive the clamping plate 8 to abut against the longitudinal beam during use. Thus, it is more convenient to clamp the chuck 2 on the longitudinal beam during use. The locking structure can be a bolt structure, a screw structure or a spring structure, etc. As an example, the locking structure includes a connecting rod 7, and the connecting rod 7 slidably penetrates through the first clamping block and / or the second clamping block. When one clamping plate 8 is provided, the connecting rod 7 is disposed at the first clamping block or the second clamping block. When two clamping plates 8 are provided, one connecting rod 7 corresponds to each of the two clamping plates 8 and respectively slidably penetrates through the first clamping block and the second clamping block. An elastic member is provided on the connecting rod 1. The elastic member is used to provide an elastic force so that the clamping plate 8 abuts against the longitudinal beam during use. The elastic member can be a tension spring sleeved on the connecting rod 7. Further, two connecting rods 7 are provided and arranged in parallel, and one end of the two connecting rods 7 away from the clamping plate 8 is fixedly connected to a pull rod. Providing two parallel connecting rods 7 can ensure the stability of the clamping plate 8 during use. The position of the clamping plate 8 can be adjusted during use by pulling the two connecting rods 7 through the pull rod.

[0037] Working principle of the present utility model: To solve the problem that it is difficult to ensure the installation accuracy of longitudinal beams during the installation and positioning of existing longitudinal beams, the present application provides an auxiliary device for installing and positioning longitudinal beams of rail vehicles, including a connecting rod 1, a measuring rod 4, and a chuck 2. A clamping groove 3 for cooperating with the longitudinal beam is provided on the chuck 2. During use, the clamping grooves 3 of the two chucks 2 are clamped on the claws under the two longitudinal beams, so that the opening dimension between the two longitudinal beams can be directly determined, eliminating the measurement and positioning process, and ensuring that the two longitudinal beams always move synchronously during subsequent adjustment, ultimately ensuring that the opening dimension meets the requirements. After adjusting the opening dimension of the longitudinal beams, extend the measuring rod 4 to both sides until the outer ends of the measuring rod 4 abut against the C-shaped grooves of the two side car bodies. At this time, the readings on the measuring rod 4 can be read to obtain the travel data of the measuring rods 4 on both sides respectively. By calculating the average travel, the distance that the two longitudinal beams need to be adjusted left and right can be determined, or the positions of the two longitudinal beams can be directly moved. During this process, the outer ends of the measuring rod 4 are always kept in contact with the C-shaped grooves of the two side car bodies until the readings of the measuring rods 4 on both sides are the same, thus directly completing the centering positioning of the longitudinal beams. The outer ends of the measuring rod 4 abutting against the C-shaped grooves of the two side car bodies can be realized through elastic members or telescopic structures. For example, a compression spring with a spring force directed towards the outer end is provided at the inner end of the measuring rod 4 so that the outer ends of the measuring rod 4 abut against the C-shaped grooves of the two side car bodies. By adopting the auxiliary device for installing and positioning longitudinal beams of rail vehicles of the present application, the measurement and positioning process in the determination of the opening dimension can be omitted, the centering positioning process of the two longitudinal beams can be simplified, thereby greatly improving the installation efficiency of the longitudinal beams. At the same time, reading errors can be reduced, and the positioning accuracy can be fully guaranteed.
