Description

Technical Field

[0001] The utility model belongs to the field of mechanical engineering, in particular to a vehicle body air conditioner flat roof installation device. Background Art

[0002] At present, the air conditioning frame is an essential component on rail vehicles. At present, the air conditioning installation of railway vehicles is mainly as follows: the air conditioning flat roof structure is installed in the area on the roof where the air conditioning equipment needs to be installed, and then the air conditioning equipment is fixedly connected to the air conditioning flat roof. Because the air conditioning equipment is located on the air conditioning flat roof, the air conditioning equipment is much higher than the roof. If the air conditioning flat roof is not installed properly on the roof, a bulge is formed in this area, and the air conditioning equipment will be higher than expected, increasing the air resistance of the vehicle when running. The air conditioning flat roof currently used requires not only to match the roof, but also to match the installation surface of the air conditioning frame. The structure is complex and difficult to install. Utility Model Content

[0003] The technical problem to be solved by the utility model is that in the prior art, during the process of car body adjustment, manufacturing and production, the air conditioner flat top may not be properly installed, resulting in the air conditioner flat top not meeting the size requirement for the height from the floor.

[0004] In order to solve the above technical problems, a technical solution provided by the utility model is:

[0005] A vehicle air conditioner flat-top installation device comprises a crossbeam and a guide arm. Two ends of the crossbeam are each provided with a guide arm, and two guide arms are connected to the crossbeam via positioning pins.

[0006] A first through hole is respectively provided at both ends of the crossbeam, a U-shaped groove is provided at one end of the guide arm close to the crossbeam, a second through hole is provided on both side walls of the U-shaped groove, and the two ends of the crossbeam are respectively placed in the corresponding U-shaped grooves on the guide arms, the second through hole and the corresponding first through hole are on the same straight line, and the first through hole and the corresponding second through hole are connected by a positioning pin, thereby connecting the crossbeam to the guide arm.

[0007] A slide groove is arranged on the cross beam between the two guide arms, two pairs of pulleys are arranged in the slide groove, a clamping block is connected under each pair of pulleys, and a hydraulic cylinder is arranged on one end of the two guide arms away from the cross beam.

[0008] Furthermore, the two pairs of pulleys can slide freely in the slide groove, that is, the distance between the two pairs of pulleys can be adjusted as needed.

[0009] Furthermore, the shape of the end of the pressing block away from the pulley fits the end surface of the longitudinal beam on the flat roof of the air conditioner to be installed.

[0010] The two clamping blocks move with the movement of the corresponding pulleys, so that the distance between the two clamping blocks can also be adjusted as needed. Because the clamping blocks correspond to the air-conditioning flat top structure, the device can adapt to the installation of aluminum alloy car body air-conditioning flat tops of different models, different positions, and different air-conditioning flat top structures.

[0011] Furthermore, the telescopic ends of the two hydraulic cylinders are respectively connected to the corresponding guide arms, and the guide arms are driven by the hydraulic cylinders. The guide arms are connected to the cross beams through positioning pins, and the clamping blocks are pressed against the longitudinal beams of the air-conditioning flat top. Driven by the hydraulic cylinders, the two clamping blocks press the longitudinal beams on both sides of the air-conditioning flat top downward at the same time until they are in fit with the arc surface of the roof dome.

[0012] The fixed ends are respectively connected to a fixed base, and the fixed base is used to fix the device when the air conditioner is installed on a flat roof.

[0013] The beneficial effects of the utility model are:

[0014] 1. In this device, driven by the hydraulic cylinder, two pressing blocks simultaneously press down the longitudinal beams on both sides of the air-conditioning flat roof until the air-conditioning flat roof fits with the arc surface of the roof dome, ensuring that the air-conditioning flat roof is installed in place, avoiding the formation of bulges, and reducing the air resistance of the vehicle when running.

[0015] 2. The distance between the two clamping blocks in this device can be adjusted as needed. The clamping blocks correspond to the two longitudinal beams on the air-conditioning flat roof structure. Therefore, this device can adapt to the installation of aluminum alloy body air-conditioning flat roofs of different models, different positions, and different air-conditioning flat roof structures, and has a wide range of adaptability.

[0016] 3. The device has a simple structure, is easy to adjust, and is simple to operate. It can realize the auxiliary installation of the flat roof of the car air conditioner, which can not only reduce the installation cost and labor, but also ensure the process size requirements.
