Description

Technical Field

[0001] This utility model relates to the field of vehicle machinery maintenance technology, specifically to a wheel set replacement device. Background Technology

[0002] In the steelmaking process, liquid trolleys are responsible for the transfer, pouring, and related auxiliary operations of high-temperature liquid metal. Typically, a liquid trolley is equipped with four sets of wheels for running on rails. When replacing or disassembling these wheels, the wheel stops are usually integrated with the end beams of the liquid trolley, making individual disassembly impossible. Therefore, the wheels cannot be removed along the length of the rails; they can only be removed laterally, perpendicular to the rails. Furthermore, the generally low height of traditional wheel sets limits the space available for lifting operations, making conventional replacement equipment difficult to use effectively in this scenario. Utility Model Content

[0003] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by this utility model is to provide a wheel set replacement device that can replace the wheel set of a hydraulic crane from the side, thereby reducing the labor load of operators, reducing personnel input and lowering costs.

[0004] To achieve the above objectives, this utility model provides a wheel set replacement device capable of quickly replacing the wheel sets of a liquid crane trolley. The liquid crane trolley is slidably connected to a track via the wheel sets. The replacement device includes a jack for lifting the liquid crane trolley, a mounting base, a support plate, a ball screw structure, and a power source. A slide rail is provided on the mounting base, with the length extension direction of the slide rail perpendicular to the length extension direction of the track. A pulley is provided at the bottom of the support plate and is slidably connected to the slide rail. The ball screw structure is connected to the support plate and the power source for transmission, and the ball screw structure is used to drive the support plate to move along the slide rail. The power source is located on the mounting base and is used to drive the movement of the ball screw structure.

[0005] Furthermore, it also includes multiple adjustable legs fixedly connected to the bottom of the mounting base. Each adjustable leg includes a connecting sleeve, a connecting rod, and a bolt. The top end of the connecting sleeve is fixedly connected to the bottom of the mounting base. The connecting rod is fixedly connected to the connecting sleeve by bolts. Multiple through holes are respectively opened on the connecting sleeve and the connecting rod along their respective length extension directions. The connecting rod is located in the inner cavity of the connecting sleeve. The bolts are connected in the through holes of the connecting sleeve and the connecting rod.

[0006] Furthermore, it also includes two stop blocks, both of which are fixedly connected to the support plate, and the two stop blocks are respectively located on both sides of the wheel set moving along the track.

[0007] Furthermore, it also includes a wireless remote control mechanism for controlling the power source, the wireless remote control mechanism including a transmitter for transmitting signals and a receiver for receiving signals, the receiver being disposed on the power source and electrically connected to the power source.

[0008] As described above, the wheel assembly replacement device of this utility model has the following beneficial effects:

[0017] See Figure 1 This utility model provides a wheel set replacement device that can quickly replace the wheel set 6 of a liquid crane trolley. The liquid crane trolley is slidably connected to a track via the wheel set 6. The replacement device includes a jack 5 for lifting the liquid crane trolley, a mounting base 1, a support plate 2, a ball screw structure 3, and a power source 4. The mounting base 1 is provided with a slide rail, the length extension direction of which is perpendicular to the length extension direction of the track. A pulley is provided at the bottom of the support plate 2, and the pulley is slidably connected to the slide rail. The ball screw structure 3 is connected to the support plate 2 and the power source 4 respectively for transmission. Structure 3 is used to drive the support plate 2 to move along the slide rail. Power source 4 is set on the mounting base 1 and is used to drive the ball screw structure 3 to move. Specifically, the ball screw structure 3 includes a screw and a nut screwed on the screw. The screw is fixedly connected to the support plate and the nut is transmitted to the power source 4. Preferably, the power source 4 is a hydraulic motor. In other embodiments, the power source 4 can also be a drive motor. Preferably, the support plate 2 is also provided with a chain structure. When the wheel set 6 is placed on the support plate 2, the support plate 2 and the wheel set 6 can be fixedly connected by the chain structure.

[0018] The basic working principle of the wheel set replacement device involved in this utility model is as follows: By setting up a mounting base 1, a support plate 2, a ball screw structure 3, and a power source 4, during disassembly, a jack 5 is placed on the track, and one side of the hydraulic crane is lifted using the jack 5. Simultaneously, the mounting base 1 is placed on the track, positioned below the wheel set 6. The power source 4 is activated, driving the ball screw structure 3 to move, which in turn moves the support plate 2 along the slide rail towards the track until the support plate 2 is positioned below the wheel set 6, thus... After the wheel assembly 6 is disassembled, it can be placed directly on the support plate 2. When the wheel assembly 6 is disassembled, the power source 4 is started to drive the ball screw structure 3 to move, which in turn drives the support plate 2 to move along the slide rail away from the track, thereby directly transporting the wheel assembly 6 out from the side. During installation, the wheel assembly 6 is placed on the support plate 2, the power source 4 is started to drive the ball screw structure 3 to move, which in turn drives the support plate 2 to move along the slide rail towards the track until it is moved under the hydraulic crane, thus facilitating the installation of the wheel assembly 6.

[0019] See Figure 1 The present invention will be further described below with reference to a specific embodiment:

[0020] In this embodiment, see Figure 1 As a preferred design, it also includes multiple adjustable support legs fixedly connected to the bottom of the mounting base 1. Each adjustable support leg includes a connecting sleeve, a connecting rod, and bolts. The top end of the connecting sleeve is fixedly connected to the bottom of the mounting base 1, and the connecting rod is fixedly connected to the connecting sleeve by bolts. Multiple through holes are opened on the connecting sleeve and the connecting rod along their respective length extension directions. The connecting rod is located in the inner cavity of the connecting sleeve, and the bolts are connected in the through holes of the connecting sleeve and the connecting rod. By setting adjustable support legs, on the one hand, the levelness of the mounting base 1 can be adjusted to prevent the mounting base 1 and the support plate 2 on the mounting base 1 from tilting. On the other hand, the height of the adjustable support legs can be adjusted according to the actual situation to meet the replacement of wheel sets 6 in different positions and improve the applicability of the replacement device.

[0021] In this embodiment, see Figure 1 As a preferred design, it also includes two stop blocks, both of which are fixedly connected to the support plate 2. The two stop blocks are located on both sides of the wheel set 6 as it moves along the track. By setting stop blocks on both sides of the support plate 2, the lateral displacement of the wheel set 6 can be restricted. On the one hand, this prevents the wheel set 6 from sliding and falling to the side, avoiding accidents such as the replacement device overturning, and improving the safety of the replacement device operation. On the other hand, during the movement of the support plate 2, its lateral sway can be reduced to a certain extent, making the movement of the support plate 2 more stable.

[0022] In this embodiment, see Figure 1As a preferred design, it also includes a wireless remote control mechanism for controlling the power source 4. The wireless remote control mechanism includes a transmitter for transmitting signals and a receiver for receiving signals. The receiver is installed on the power source 4 and electrically connected to the power source 4. Through the transmitter and receiver, the power source 4 can be controlled remotely, which greatly improves the efficiency and convenience of operation and provides a foundation for intelligence and automation. At the same time, it can achieve rapid shutdown in case of emergencies, such as overload of the power source 4, which is faster than manual shutdown on site and can reduce the possibility of the accident escalating to a certain extent.

[0023] As can be seen from the above, the wheel replacement device of this utility model has the following beneficial effects:

[0024] By setting up mounting base 1, support plate 2, ball screw structure 3, and power source 4, the wheel set 6 can be quickly changed in a limited space. It has low requirements for top space and is suitable for narrow spaces. At the same time, it has low operating cost, simple structure, and convenient operation. It can also reduce the safety risks of operators and reduce the workload of operators.

[0025] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0026] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
