Description

Technical Field

[0001] This utility model relates to the field of track chain repair technology for mining bulldozers, and more specifically, to a track chain repair device. Background Technology

[0002] Mining bulldozers play a crucial role in mining operations. Most of these bulldozers use tracked drives for movement. The relatively large contact area between the tracks and the ground significantly increases the friction between the machine and the ground. This friction is one of the power sources for the bulldozer, making its operation more stable and reliable.

[0003] However, track wear varies depending on the operating environment. Generally, the wear cycle of tracks is about 3 to 4 months. For example, a 580-horsepower bulldozer uses 24 tracks per year, and a 320-horsepower bulldozer also uses 24 tracks. Since tracks are consumable parts, traditional maintenance methods mainly include replacing track shoes or stopping the machine to weld and repair wear strips. However, if the track links deteriorate, a new track assembly must be installed. Replacing track shoes undoubtedly increases the workload of maintenance workers. Maintenance workers need to expend a lot of physical strength and time on the replacement operation, which also increases costs. While stopping the machine to weld and repair can extend the track's lifespan to some extent, it reduces the equipment's operating efficiency. There is also a risk of damaging the computer board during the welding process. Furthermore, this method requires the driver to cooperate, constantly moving the track position, which brings many inconveniences to operation. In contrast, directly installing a new track assembly can quickly solve the problem, but it significantly increases operating costs. Each of these maintenance methods has its drawbacks. Finding a more efficient, economical, and reliable track maintenance method has become an urgent problem for mining companies. Summary of the Invention

[0004] To address the high cost, time-consuming, and labor-intensive technical problems associated with traditional bulldozer track repair and replacement, a track chain repair device is provided. This invention solves the problem of downtime welding tracks affecting production, significantly reduces worker workload and welding / repair time, and allows for non-stop welding and repair of various types of iron wheel track devices. This saves manpower, improves labor efficiency, enhances repair quality, and reduces maintenance costs. Furthermore, it is simple to operate and safe and reliable.

[0005] The technical means adopted in this utility model are as follows:

[0006] A track chain repair device includes: a control switch, a first motor, a second motor, a reducer, a support wheel, a drive wheel, a guide wheel, a hydraulic cylinder, and a hydraulic tank;

[0007] There are two control switches, which are connected to the first motor and the second motor respectively;

[0008] The first motor is connected in sequence to the reducer and the drive wheel;

[0009] The second motor is connected to the oil cylinder and the hydraulic tank.

[0010] Furthermore, the power supply, via an AC contactor and the control switch, enables independent power supply control for the two motors.

[0011] Furthermore, the control switches control the power supply to the two motors respectively to realize the operation of the drive mechanism and the tensioning mechanism.

[0012] Furthermore, the gear ratio of the reducer is 15:1.

[0013] Furthermore, the power of the first motor is 22 kilowatts, and the power of the second motor is 10 kilowatts.

[0014] Furthermore, the tracks rotate on the track chain machine via the first and second motors as power sources.

[0015] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0016] 1. The present invention provides a track chain repair device. This device can repair different types of iron wheel track devices without stopping the vehicle, and does not require a large amount of manpower for tedious operations as in the traditional method, thus saving manpower.

[0017] 2. The track chain repair device provided by this utility model can precisely control the welding repair part through the control device, and can realize the repair of various types of track devices without stopping the machine. It can significantly shorten the repair time, improve the efficiency of equipment use, and thus improve labor efficiency.

[0018] 3. The track chain repair device provided by this utility model addresses the issue that traditional welding repair methods, such as those involving stopping the track, pose a risk of damaging the computer board, and the welding effect may be affected by factors such as inconvenient operation. This device, through its control mechanism, precisely controls the welding area, enabling more accurate welding operations on the parts of the track that need repair. This avoids welding quality problems caused by improper operation or environmental factors, thereby improving the quality of repairs.

[0019] 4. The track chain repair device provided by this utility model can perform welding repairs without stopping the machine, reducing losses caused by downtime and some unnecessary high costs, thereby reducing maintenance costs.

[0024] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this utility model or its application or use. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0027] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0028] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0029] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation besides the orientation of the device as described in the figures. For example, if the device in the figures is inverted, a device described as "above" or "above" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0030] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0031] like Figure 1 As shown, this utility model provides a track chain repair device, including: a control switch, a first motor 8, a second motor 5, a reducer 6, a support wheel 2, a drive wheel 1, a guide wheel 4, a hydraulic cylinder 3, and a hydraulic tank 7;

[0032] There are two control switches, which are connected to the first motor 8 and the second motor 5 respectively.

[0033] The first motor 8 is connected in sequence to the reducer 6 and the drive wheel 1;

[0034] The second motor 5 is connected to the oil cylinder 3 and the hydraulic tank 7.

[0035] Furthermore, the track that needs repair is installed on the track chain machine, and the tension of the track is adjusted by the tensioning mechanism driven by the second motor 5 to ensure proper installation.

[0036] Furthermore, the first motor 8 is started, causing the track to rotate at a certain speed. The user can adjust the rotation speed and position of the track in a timely manner according to the needs of the welding part by controlling the switch. At the same time, the track can be repaired with welding tools. Since the track can rotate, the complexity of the welding process and the workload of the welder are reduced. Moreover, the machine is not stopped for track repair welding, which greatly shortens the welding and maintenance time and improves the welding quality.

[0037] Furthermore, the power supply, via an AC contactor and the control switch, enables independent power supply control for the two motors.

[0038] Furthermore, the control switches control the power supply to the two motors respectively to realize the operation of the drive mechanism and the tensioning mechanism.

[0039] Furthermore, when it is necessary to adjust the tension of the track, the second motor 5 is powered by the control switch. After the second motor 5 starts, it drives the hydraulic cylinder 3 and the hydraulic tank 7 to work, so that the track is tensioned on the track chain machine. In this way, different models of track can be installed on the track chain machine, ensuring that the track is in a suitable repair state during the repair process.

[0040] Furthermore, the gear reducer 6 has a transmission ratio of 15:1.

[0041] Furthermore, setting the transmission ratio allows the track to obtain appropriate speed and torque, meeting the requirements for track rotation during the repair process.

[0042] Furthermore, the power of the first motor 8 is 22 kilowatts, and the power of the second motor 5 is 10 kilowatts.

[0043] Furthermore, the track rotates on the track chain machine via the first motor 8 and the second motor 5 as power sources.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
