[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-6 The utility model provides an embodiment: a rail transit motor vehicle door carrier, comprising an inverted U-shaped connecting frame 1 and a right-angle door carrier 2 fixed at the top of the inverted U-shaped connecting frame 1, a rectangular lower groove 3 is arranged on one side of the back of the right-angle door carrier 2, and two symmetrical arc-shaped steel plates are arranged on both inner walls of the rectangular lower groove 3;

[0020] An I-shaped support 4 is bolted to both inner walls of the right-angle door frame 2, a C-shaped sheet metal seat 6 is slidably installed inside the I-shaped support 4, a roller 7 is rotatably installed at one end of the C-shaped sheet metal seat 6 away from the I-shaped support 4, and a screw rod distance adjustment structure 8 for driving the C-shaped sheet metal seat 6 to slide is arranged inside the I-shaped support 4;

[0021] When the screw rod pitch adjustment structure 8 drives the C-shaped sheet metal seat 6 and the roller 7 to slide, the C-shaped sheet metal seat 6 will slide relative to the I-shaped support seat 4. The structural design of the I-shaped support seat 4 and the C-shaped sheet metal seat 6 improves the working stability of the roller 7 and maintains a good contact state between the roller 7 and the guide column.

[0022] The roller 7 is made of stainless steel, which has high strength and hardness and can withstand large pressure and load, thus ensuring the stability and reliability of the roller 7 during operation. In particular, when the roller 7 is subjected to the weight of the door and is frequently opened and closed, the stainless steel wheel can maintain a good working condition, thus reducing the possibility of deformation or damage of the roller 7 due to stress.

[0023] A right-angled bent edge 5 is integrally formed on one side of the I-shaped support 4 away from the C-shaped sheet metal seat 6, and foot supports 501 are integrally formed on the outer walls of both sides of the right-angled bent edge 5. The foot supports 501 and the inner walls of the right-angled door frame 2 are bolted to each other. A right-angled bent edge 5 and the foot supports 501 are integrally formed on one side of the I-shaped support 4 away from the roller 7. The foot supports 501 are bolted to the two inner walls of the right-angled door frame 2. The staff can disassemble and assemble the I-shaped support 4 and the right-angled door frame 2 through the foot supports 501 and bolts, so as to achieve the purpose of replacing the roller 7;

[0024] The screw pitch adjustment structure 8 includes a connecting plate 801 fixed on the outer wall of one side of the I-shaped support 4, and a threaded shaft 802 rotatably mounted on the outer wall of one side of the connecting plate 801, the top of the threaded shaft 802 penetrates the outside of the right-angle bent edge 5, a nut sleeve 804 is fixed on the outer wall of one side of the C-shaped sheet metal seat 6, the nut sleeve 804 and the threaded shaft 802 are threadedly assembled, and a T-shaped knob 803 is fixed on the top of the threaded shaft 802, and the T-shaped knob 803 is located between the two foot supports 501;

[0025] The staff turns the T-knob 803, and the T-knob 803 drives the threaded shaft 802 to rotate, and then the threaded shaft 802 drives the nut sleeve 804 and the C-shaped sheet metal seat 6 to slide. Through the screw adjustment structure 8, the roller 7 can be quickly adjusted to a certain extent, reducing maintenance time; and because the roller 7 always maintains a good contact state with the guide column, friction and vibration are reduced, which can effectively reduce the noise and vibration generated during the movement of the door.

[0026] When the embodiment of the present application is in use, the staff first clamps the right-angle door carrying frame 2 on the guide column on the top wall of the car through the rectangular lower groove 3 and the arc-shaped steel plate on the inner wall of the rectangular lower groove 3, and connects the right-angle door carrying frame 2 to the door moving mechanism, and then fixes the door to the bottom end of the inverted U-shaped connecting frame 1. When the door moving mechanism is started, the door carrying frame will transmit power and movement to the door, so that the door can be opened or closed smoothly. In this process, the door carrying frame bears the responsibility of bearing and stabilizing the door, ensuring that the door remains stable during movement and does not deviate or swing. When the carrying frame is initially adjusted After the test, the staff adjusts the distance between the C-shaped sheet metal seat 6, the roller 7 and the guide rail through the screw distance adjustment structure 8 until the roller 7 is tightly against the guide post. At this time, the roller 7 and the guide post always maintain close contact, which can effectively prevent the door from deviating or swinging during movement, thereby improving the operational performance and safety of the door. The carrying frame can ensure that the roller 7 always maintains good contact with the guide post according to the wear between the roller 7 and the guide post through the screw distance adjustment structure 8, thereby extending the service life of the guide device, thereby reducing the number of replacement times of the roller 7, and reducing maintenance costs and workload.
