[0030] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0031] Reference Figure 1 - Figure 3The utility model provides an embodiment of a train head cover mounting bracket, comprising a support plate 1 for supporting the overall device. Before installing the head cover, the overall device needs to be installed in advance at the operating site. During installation, it is necessary to ensure that the top of the support plate 1 is parallel to the working plane. A moving component 2 is provided on the top of the support plate 1 for facilitating personnel to move to the top of the support block 4. A hydraulic push rod 3 is installed at the bottom end of the support plate 1 for driving the support block 4 to move up and down. The top of the hydraulic push rod 3 is fixedly connected to a support block 4 for an operator to stand on. A motor 6 is installed at the rear end of the support block 4 for driving a threaded rod 8 to rotate. The front end of the output shaft of the motor 6 is fixedly connected to a threaded rod 8 for driving the fixed block 5 to move left and right. The inner wall of the support block 4 is slidably connected to a fixed The fixing block 5 of the vehicle hood is set to be L-shaped. When the vehicle hood needs to be installed, the motor 6 needs to be started first to drive the threaded rod 8 to rotate. The threaded rod 8 and the fixing block 5 are threadedly connected. The rotation of the threaded rod 8 can drive the fixing block 5 to move outward until it contacts the outer wall of the vehicle hood. At this time, the horizontal part of the fixing block 5 will be supported at the bottom end of the vehicle hood, and the vertical part of the fixing block 5 will be fixed to the outer wall of the vehicle hood. The right end of the support block 4 is provided with a transport component 7 for facilitating the transport device. The moving component 2 includes a slide groove 21 for movement of a slider 26. The slide groove 21 is provided at the top end of the support plate 1. The top end of the slide groove 21 is slidably connected to a slider 26 for limiting the bottom end of the main connecting rod 24. The top end of the slider 26 is rotatably connected to the main connecting rod 24 for driving the pedal 23 to move.

[0032] Reference Figure 1 , Figure 4 , Figure 5The conveying assembly 7 includes a sleeve 72 for accommodating a slide plate 73. The left end of the sleeve 72 is rotatably connected to the right end of the support block 4. When the support block 4 moves up and down, the sleeve 72 is driven to rotate. The bottom end of the sleeve 72 slides with a slide plate 73 for the device to slide. The top of the slide groove 21 is close to the bottom end of the slide plate 73 and is slidably connected with a moving block 74 for driving the slide plate 73 to move. The bottom end of the slide plate 73 is rotatably connected to the inner wall of the moving block 74. When the moving block 74 moves left and right, it drives the bottom end of the slide plate 73 to move left and right. The top of the support plate 1 is close to the front end of the slide groove 21 and is provided with a limiting groove 71 for the handle 77 to move. The inner wall of the limiting groove 71 is slidably connected to drive the moving block 74 The handle 77 that moves left and right has a rear end fixedly connected to the front end of the moving block 74. The moving block 74 can be driven to move left and right by moving the handle 77. The front end of the handle 77 is slidably connected to a positioning block 78 for fixing the handle 77. The inner wall of the limiting groove 71 is provided with a positioning groove 76 for accommodating the positioning block 78. The positioning groove 76 and the positioning block 78 are adapted to each other. When the positioning block 78 is inserted into the positioning groove 76, the handle 77 will be fixed and cannot move left and right. The rear end of the positioning block 78 is fixedly connected to a fixing spring 75 for pushing the positioning block 78 forward. The rear end of the fixing spring 75 is fixedly connected to the front end of the handle 77, and the fixing spring 75 will always push the positioning block 78 forward.

[0033] Reference Figure 1 - Figure 3 The left end of the support block 4 is rotatably connected to a main shaft 22 for supporting the rotation of the main connecting rod 24. The top end of the main connecting rod 24 is fixedly connected to the outer wall of the main shaft 22. When the support block 4 moves upward, the main connecting rod 24 is driven to rotate upward through the main shaft 22. The rear end of the main connecting rod 24 is rotatably connected to a moving shaft 27 for driving the pedal 23 to move. The outer wall of the moving shaft 27 is fixedly connected to a pedal 23 for the operator to step on. The front end of the pedal 23 is fixedly connected to a rotating shaft 28 for driving the pedal 23 to rotate. The left end of the support block 4 is hinged near the bottom end of the main shaft 22. The secondary connecting rod 25 is used to drive the pedal 23 to rotate, and the front end of the rotating shaft 28 is rotatably connected to the rear end of the secondary connecting rod 25. When the main connecting rod 24 drives the pedal 23 to move upward through the movable shaft 27, the secondary connecting rod 25 will force the pedal 23 to rotate to face the front side upward by squeezing the rotating shaft 28. The left end of the support block 4 is fixedly connected to the top of the main rotating shaft 22 to protect the main rotating shaft 22. There are multiple groups of protective plates 29, and the multiple groups of protective plates 29 are symmetrically arranged with the center line of the support block 4 as the symmetry axis. Another group of protective plates 29 can protect the connection between the sleeve 72 and the fixed block 5.

[0034] Working principle: when the hood needs to be installed, the hood needs to be moved to the front end of the support block 4 first, and then the motor 6 can be started to drive the threaded rod 8 to rotate. The rotation of the threaded rod 8 will drive the fixed block 5 to move outward until the vertical part of the fixed block 5 is close to the outer wall of the hood, and then the hydraulic push rod 3 can be started to drive the support block 4 to move upward. The upward movement of the support block 4 will drive the hood to move upward through the fixed block 5 so that its rear end is aligned with the vehicle body. While the support block 4 moves upward, the support block 4 will drive the main connecting rod 24 to rotate upward, and the main connecting rod 24 will drive the pedal 23 to move upward through the moving shaft 27. At the same time, the rotating shaft 28 will drive the pedal 23 to rotate under the restriction of the secondary connecting rod 25 to keep the front side facing upward. When the support block 4 stops moving, the moving assembly 2 will also stop moving. The operator can install the hood by moving the pedal 23 upward to the top of the support block 4.

[0035] When the device needs to be transported to the top of the support block 4, you can first hold the handle 77 and then press the positioning block 78 to move it backward and out of the positioning groove 76. Then you can move the handle 77 left and right to drive the moving block 74 to move left and right. The left and right movement of the moving block 74 will drive the movement and rotation of the slide plate 73. When the inclination angle of the slide plate 73 and the sleeve 72 is sufficient for the device to move, the positioning block 78 can be released. The positioning block 78 will re-enter the interior of the positioning groove 76 under the push of the fixing spring 75 to re-fix the handle 77. At this time, the slide plate 73, the sleeve 72, and the moving block 74 will also be fixed and unable to move. The device with the moving wheels can be directly pushed to move it to the top of the support block 4 through the slide plate 73 and the sleeve 72.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
