Description

Technical Field

[0001] This utility model relates to the field of dynamic support technology, specifically a locomotive wheel-driven dynamic support. Background Technology

[0002] In the maintenance and repair of railway locomotives, the motor units of HXD locomotive wheels are critical components that frequently need to be moved and transported. Traditional methods of transporting motor units have many drawbacks. Using simple lifting equipment such as electric hoists is not only cumbersome to operate, requiring multiple people to work together and consuming a lot of manpower, but also, due to the lack of precise positioning and stable support during lifting and moving, the motor units are easily prone to shaking and collisions, causing damage and affecting their subsequent normal use.

[0003] Some of the temporary support structures are unstable and cannot withstand the heavy weight of the motor units, posing significant safety hazards during transport. Furthermore, these traditional methods make equipment storage difficult after transport and require substantial space. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a locomotive wheel drive movable support frame.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A locomotive wheel drive movable support frame includes a support frame; the support frame is welded together from two parallel steel plates and a horizontal steel plate at the bottom end, and an axle is welded to the bottom end of the support frame, with a pair of load-bearing wheels rotatably connected to both ends of the axle.

[0007] The top of the support frame is welded with a clamping plate perpendicular to it, and a support plate fixed to the support frame is welded below the clamping plate. The clamping plate and the support plate are arranged parallel to each other. A pair of fixing pins are inserted into the clamping plate and the support plate near their respective ends. There is a gap between the clamping plate and the support plate, and the height of the gap between the clamping plate and the support plate is less than the height of the fixing pins.

[0008] Preferably, a ring is welded to the top of the fixing pin, and a through hole is opened at the bottom of the fixing pin below the support plate.

[0009] Preferably, a diagonal bar is welded to the middle of the support frame, and the other end of the diagonal bar is welded to the wheel axle to form a triangular support structure.

[0012] Preferably, the clamping plate and the support plate are provided with pin holes at the corresponding fixing pin positions.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. Insert the motor assembly protrusion into the gap between the clamp plate and the support plate, and complete the installation by passing the fixing pin through the pin hole; the ring at the top of the fixing pin is easy to insert and remove, and the through hole at the bottom can be fixed with the help of auxiliary tools to prevent it from falling off and ensure a stable connection.

[0015] 2. The support frame is welded from two parallel steel plates and a bottom horizontal steel plate. There is a diagonal bar in the middle that is connected to the wheel axle to form a triangular support structure.

[0025] Example

[0026] like Figure 1-3 As shown, a locomotive wheel drive movable support frame includes a support frame 1;

[0027] First, precisely engage the protrusion of the motor unit on the HXD locomotive wheel drive into the gap between the clamping plate 4 and the support plate 5 on the outside of the support frame 1; the clamping plate 4 and the support plate 5 should fit tightly against the motor unit protrusion to ensure a preliminary and stable connection; after engagement, pass the fixing pin 6 through the pin hole 7 opened on the protrusion, clamping plate 4 and support plate 5; the ring 61 welded to the top of the fixing pin 6 provides a convenient point of leverage for the operator, facilitating insertion and removal; and the through hole 62 opened at the bottom of the fixing pin 6 below the support plate 5 can be further fixed with auxiliary tools to prevent the fixing pin 6 from accidentally falling off during operation, thus completing the installation of the movable support frame.

[0028] Principles of Movement and Support

[0029] Support frame 1 is welded from two parallel steel plates and a bottom horizontal steel plate, resulting in a stable shape. A diagonal brace is welded in the middle to connect with the wheel axle 2, forming a triangular support structure. An X-shaped frame is also welded between the parallel steel plates, greatly enhancing the overall stability. This robust structural design effectively distributes the weight of the motor unit, ensuring that the movable support frame will not deform or be damaged during movement.

[0030] The bottom of the support frame 1 is welded with a wheel axle 2, and a pair of load-bearing wheels 3 are rotatably connected to both ends. The load-bearing wheels 3 are 483mm high and 300mm in diameter, and each can bear a weight of up to 3000KG. Its strong load-bearing capacity can easily meet the heavy load requirements of the HXD locomotive wheel motor unit. After installation, the operator only needs to push the movable support frame, and the load-bearing wheels 3 can roll on the ground to move the motor unit.

[0031] Support frame 1: It is welded from two parallel steel plates and a bottom horizontal steel plate, and has a stable shape. The diagonal bar welded in the middle is connected to the wheel axle 2 to form a triangular support structure.

[0032] Wheel axle 2 and load-bearing wheel 3: Wheel axle 2 is welded to the bottom of support frame 1, and a pair of load-bearing wheels 3 are rotatably connected at both ends; the load-bearing wheel 3 is 483mm high and 300mm in diameter, and can bear a weight of up to 3000KG, which can adapt to various heavy load requirements.

[0033] Clamping plate 4 and support plate 5: A vertical clamping plate 4 is welded to the top of the support frame 1, and a support plate 5 fixed to the support frame 1 is welded to the bottom. The two are arranged in parallel. A pair of fixing pins 6 are inserted near the two ends, and there is a gap between the clamping plate 4 and the support plate 5. The height of the gap is less than the height of the fixing pins 6. The motor unit on the wheel drive of the HXD locomotive wheel is welded with a protrusion that is engaged in the gap between the clamping plate 4 and the support plate 5. The protrusion has a pin hole for the fixing pins 6 to pass through.

[0034] Fixing pin 6: The top end is welded with a circular ring 61 for easy operation, and the bottom end is provided with a through hole 62 located below the support plate 5 for easy installation and fixing.
