Description

Technical Field

[0001] This invention relates to the field of electric shovel support rollers, and particularly to a mounting device for support rollers. Background Technology

[0002] Heavy-duty electric shovel support rollers are the core load-bearing components of the walking system of large mining electric shovels, primarily used to support the weight of equipment weighing hundreds or even thousands of tons and achieve stable movement. This component is forged from high-strength alloy steel and, through a precision-machined wheel structure combined with the track tracks, evenly distributes the weight of the electric shovel to the ground while simultaneously bearing the enormous dynamic loads during excavation operations. Its core functions are reflected in three aspects: first, acting as a force transmission hub, distributing the equipment's own weight and operational impact forces to the track system; second, achieving low-friction rolling through the bearing system, ensuring the electric shovel's mobility and flexibility in complex mining environments; and third, maintaining a stable connection with the tracks through a wear-resistant wheel flange design, preventing derailment. As a key component of mining equipment, its installation accuracy and reliability directly affect the operational safety and service life of the electric shovel, making it a crucial mechanical component for ensuring continuous mining operations.

[0003] Currently, the installation of support rollers for heavy-duty electric shovels mainly relies on manual operation, in conjunction with lifting equipment, which has significant drawbacks in actual operation. Since a single support roller can weigh over 700 kilograms, and the installation space is limited, workers must perform precise alignment in confined spaces, posing safety hazards such as crushing and easily causing collision damage to components. Traditional installation processes lack specialized positioning fixtures, relying entirely on experience for adjustments, resulting in repeated repositioning and damage to bearing mating surfaces. This inefficient and dangerous installation method severely restricts equipment maintenance efficiency and increases downtime for repairs.

[0004] Therefore, it is necessary to study an installation device for support rollers to solve the above problems or mitigate their effects. Summary of the Invention

[0005] This invention provides an installation device for track rollers. Through the design of the forklift and the mounting rod, and the cooperation between the mounting column and the mounting sleeve, the mechanized and precise installation of heavy track rollers can be achieved, so as to effectively solve the above-mentioned problems or alleviate the impact of the above-mentioned problems.

The lead screw is rotatably connected between the first connecting ring and the second connecting ring. The drive ring is threadedly connected to the lead screw. The two ends of the transmission rod are respectively connected to the drive ring and the top ring. The lead screw is configured to rotate under the action of a driving force, so that it drives the drive ring to move the transmission rod and the top ring along the axial direction of the mounting rod through the threaded engagement.

[0010] In one embodiment, the drive ring has a through connecting groove, and the drive ring is slidably connected to the connecting plate through the connecting groove.

[0015] In one embodiment, the mounting rod has two insertion holes distributed along its axial direction, each insertion hole is fitted with a pin, and the ends of the two pins are provided with limiting plates, which respectively fit against the support roller and the mounting column.

[0016] The mounting device for support rollers provided by this invention has at least the following advantages compared with the prior art: The mounting device for track rollers of the present invention uses a forklift to move and adjust the mounting rod, and a drive mechanism drives the top ring to push the track roller and mounting post to slide along the mounting rod, so that the mounting post can be precisely embedded into the mounting sleeve. This enables mechanized and precise installation of heavy-duty track rollers, replacing hoisting and manual alignment, and improving safety and efficiency. Attached Figure Description

Detailed Implementation

[0021] The invention will now be further described with reference to the accompanying drawings.

[0022] like Figures 1 to 6 As shown, the mounting device for track rollers of the present invention may include a forklift 2, a mounting sleeve 5, a mounting rod 3, a mounting post 7, a top ring 15, and a drive mechanism. The mounting sleeve 5 is fixedly connected to the track chain body 1; one end of the mounting rod 3 is connected to the fork arm of the forklift 2, and the other end is inserted into the mounting sleeve 5 and coaxial with the mounting sleeve 5; the mounting post 7 is located on the side of the track chain body 1 of the track roller 6, and both the mounting post 7 and the track roller 6 are sleeved on the mounting rod 3, with the mounting post 7 matching the mounting sleeve 5; the top ring 15 is sleeved on the mounting rod 3 and located on the side of the track roller 6 away from the mounting post 7; the drive mechanism is located on the mounting rod 3, and the drive mechanism is configured to drive the top ring 15 to move axially along the mounting rod 3 toward the mounting sleeve 5, so that the mounting post 7 can be embedded in the mounting sleeve 5.

[0023] Specifically, the installation device uses the fork arm of the forklift 2 to support and move the installation rod 3, providing stable hydraulic lifting and horizontal movement functions, making the installation process adjustable and controllable. The installation sleeve 5 is fixed to the track rail body 1 and can be a sleeve structure made of high-strength steel. Its interior has an inner cylinder structure that matches the installation post 7, which can fix the installation post 7 and thus the support roller 6. One end of the installation rod 3 is connected to the fork arm of the forklift 2, and the other end can be designed as a cylindrical guide shaft, which can be inserted into the installation sleeve 5 and remain coaxial. The installation rod 3 serves as the core guiding component for the entire installation process, ensuring precise alignment between the installation post 7, the support roller 6, and the installation sleeve 5. The installation post 7 is fixed to the side of the support roller 6 near the track rail body 1. The installation post 7 is integral with the support roller 6 or connected by bolts and is sleeved on the installation rod 3. The outer diameter of the installation post 7 matches the inner diameter of the installation sleeve 5 so that it can be inserted into the installation sleeve 5 for fixation. The top ring 15 is fitted onto the mounting rod 3 and located on the side of the support roller 6 opposite to the mounting column 7, enabling it to evenly push the support roller 6 towards the mounting sleeve 5 during installation. The drive mechanism is mounted on the mounting rod 3 and can be a mechanical transmission structure, capable of driving the top ring 15 to move axially along the mounting rod 3, thereby smoothly pushing the mounting column 7 into the mounting sleeve 5.

[0024] During installation, the forklift 2 is moved and adjusted to insert the mounting rod 3 into the mounting sleeve 5 and maintain coaxiality, achieving initial positioning. The drive mechanism is then activated, driving the top ring 15 to push the support roller 6 and mounting post 7 along the mounting rod 3 towards the mounting sleeve 5, allowing the mounting post 7 to precisely embed into the mounting sleeve 5, thus completing the installation. This enables mechanized and precise installation of the heavy-duty support roller 6, replacing hoisting and manual alignment, improving safety and efficiency.

[0025] Furthermore, the mounting sleeve 5 may be provided with a shaft hole that matches the mounting rod 3, so that the mounting rod 3 and the mounting sleeve 5 can remain coaxial. In one example, the drive mechanism includes a fixed frame and a drive frame. The fixed frame is mounted on the mounting rod 3, and the drive frame is mounted on the fixed frame. The drive end of the drive frame is connected to the top ring 15.

[0026] Specifically, the fixing frame can be a ring or frame structure, and can be fixed to the mounting rod 3 by bolts or snap-fit, providing a stable mounting base for the drive frame. The drive frame is mounted on the fixing frame, and its drive end is connected to the top ring 15, driving the top ring 15 to move axially along the mounting rod 3 via mechanical transmission. In this way, the fixing frame ensures that the drive mechanism is relatively fixed to the mounting rod 3, and the drive frame can push the top ring 15 to achieve linear advancement.

[0027] In one example, such as Figure 5 and Figure 6 As shown, the fixing frame includes a first connecting ring 10 and a second connecting ring 11 sleeved on the mounting rod 3. The first connecting ring 10 and the second connecting ring 11 are fixedly connected by a connecting plate 25, and the first connecting ring 10 is fixedly connected to the assembly ring 8 on the mounting rod 3.

[0028] Specifically, both the first connecting ring 10 and the second connecting ring 11 can be annular components sleeved on the mounting rod 3. The first connecting ring 10 and the second connecting ring 11 can be welded or bolted together by 2 to 6 connecting plates 25 to form a rigid frame. The assembly ring 8 is fixed to the mounting rod 3 to lock with the first connecting ring 10, ensuring that the entire fixing frame does not slide or rotate along the mounting rod 3. In this way, the first connecting ring 10 and the assembly ring 8 are locked together, and the second connecting ring 11 is fixed to the first connecting ring 10 by the connecting plate 25, forming a stable support structure to provide rigid support and prevent the drive mechanism from shifting or vibrating under force.

[0029] In one example, such as Figures 3 to 5As shown, the drive frame includes a lead screw 12, a drive ring 13, and a transmission rod 14. The lead screw 12 is rotatably connected between the first connecting ring 10 and the second connecting ring 11. The drive ring 13 is threadedly connected to the lead screw 12. The two ends of the transmission rod 14 are respectively connected to the drive ring 13 and the top ring 15. The lead screw 12 is configured to rotate under the action of driving force, so that it drives the drive ring 13 to move the transmission rod 14 and the top ring 15 along the axial direction of the mounting rod 3 through the threaded engagement.

[0030] Specifically, the two ends of the lead screw 12 are respectively mounted on the first connecting ring 10 and the second connecting ring 11 via bearings, and the lead screw 12 can be driven to rotate manually or electrically. A mounting protrusion protrudes from the drive ring 13, and the mounting protrusion has an internal thread that mates with the external thread of the lead screw 12. The drive ring 13 converts the rotational motion of the lead screw 12 into the linear motion of the transmission rod 14 through this threaded engagement. One side of the drive ring 13 is connected to one end of the transmission rod 14, and the other end of the transmission rod 14 is connected to the top ring 15. During installation, rotating the lead screw 12 drives the drive ring 13 to move axially along the lead screw 12, which in turn pushes the top ring 15 via the transmission rod 14. The top ring 15 then pushes the support roller 6 and the mounting post 7. This achieves effortless and smooth linear propulsion, avoiding damage to the bearings of the support roller 6 caused by impact loads.

[0031] Furthermore, the transmission rods 14 can be two symmetrically arranged rods to transmit thrust to the top ring 15. A handwheel 27 can be provided at the end of the lead screw 12 away from the second connecting ring 11 for manually driving the lead screw 12 to rotate.

[0032] In one example, the drive ring 13 has a through connecting groove 24, and the drive ring 13 is slidably connected to the connecting plate 25 through the connecting groove 24.

[0033] Specifically, the drive ring 13 has 2 to 6 symmetrically arranged connecting slots 24 through it, and the drive ring 13 is slidably connected to the connecting plate 25 through the connecting slots 24. The connecting slots 24 can be rectangular, and their cross-section matches that of the connecting plate 25. In this way, the drive ring 13 is guided to move linearly along the connecting plate 25 through the connecting slots 24, which can prevent it from rotating with the lead screw 12, ensure that the thrust direction is consistent, improve transmission stability, avoid the top ring 15 from being skewed due to the rotation of the drive ring 13, and avoid transmission jamming.

[0034] In one example, the second connecting ring 11 has a through guide hole 19, and the transmission rod 14 slides through the guide hole 19.

[0035] Specifically, the second connecting ring 11 has two symmetrically arranged guide holes 19. The two transmission rods 14 are slidably connected to the second connecting ring 11 through the two guide holes 19. The design of the guide holes 19 allows the transmission rods 14 to slide smoothly within the second connecting ring 11, ensuring the linear motion trajectory of the top ring 15 and preventing deviation during thrust transmission. The guide holes 19 can be smooth circular holes with a diameter slightly larger than the diameter of the transmission rods 14, allowing the transmission rods 14 to slide freely within the guide holes 19, serving as guides and limits.

[0036] In one example, both the assembly ring 8 and the first connecting ring 10 are provided with threaded holes 17, and the threaded holes 17 corresponding to the assembly ring 8 and the first connecting ring 10 are connected by the first locking bolt 9.

[0037] Specifically, both the assembly ring 8 and the first connecting ring 10 are provided with two symmetrically distributed threaded holes 17. The two sets of threaded holes 17 on the assembly ring 8 and the first connecting ring 10 are connected one-to-one by the first locking bolt 9, that is, the threaded part of the first locking bolt 9 passes through the threaded holes 17 on the assembly ring 8 and the first connecting ring 10 in sequence. In this way, a rigid connection is achieved by bolt tightening, ensuring that there is no relative displacement between the fixing frame and the mounting rod 3, and improving the overall structural rigidity. Furthermore, the symmetrical design of the threaded holes 17 allows the first locking bolt 9 to apply force evenly to fix the first connecting ring 10, avoiding the skew problem caused by unilateral force, and ensuring the coaxial accuracy of the connection structure.

[0038] In one example, two symmetrically arranged clamping plates 18 are fixedly connected to the side of the first connecting ring 10 near the assembly ring 8, and the first connecting ring 10 is engaged with the assembly ring 8 through the two clamping plates 18.

[0039] Specifically, two symmetrically arranged clamping plates 18 are fixedly connected to the side of the first connecting ring 10 near the assembly ring 8. The first connecting ring 10 is engaged with the assembly ring 8 through the two clamping plates 18. The engagement between the clamping plates 18 and the assembly ring 8 provides an initial positioning reference for the first connecting ring 10, which facilitates subsequent bolt locking, simplifies the assembly process, and enhances torsional resistance.

[0040] Furthermore, the card plate 18 can be an L-shaped or T-shaped steel component, connected to the first connecting ring 10, and cooperates with the groove or flange on the assembly ring 8 to achieve rapid positioning and initial fixation.

[0041] In one example, the mounting rod 3 has a radially penetrating insertion groove 4, and the mounting rod 3 is sleeved on the fork arm of the forklift 2 through the insertion groove 4; and a second locking bolt 16 is threadedly connected to one side of the mounting rod 3 corresponding to the insertion groove 4, and the end of the screw of the second locking bolt 16 abuts against the fork arm of the forklift 2.

[0042] Specifically, a radially penetrating insertion groove 4 is provided on one side of the mounting rod 3, through which the mounting rod 3 connects to the fork arm of the forklift 2. A second locking bolt 16 is connected to the side of the mounting rod 3 in the insertion groove 4. The end of the screw of the second locking bolt 16 fits against the fork arm of the forklift 2. The design of the second locking bolt 16 enables a reliable connection between the mounting rod 3 and the fork arm of the forklift 2, ensuring that there is no relative displacement between the two during operation and improving the stability of the entire mounting tool.

[0043] Furthermore, the insertion slot 4 can be a rectangular slot, slightly larger than the fork arm, to facilitate quick installation and disassembly. The second locking bolt 16 can be an internal hex bolt, which, when tightened, presses against the fork arm to prevent the mounting rod 3 from sliding or falling off.

[0044] In one example, the mounting rod 3 has two insertion holes 20 distributed along its axis, and a pin 21 is inserted into each insertion hole 20. The ends of the two pins 21 are provided with limiting plates 22, and the two limiting plates 22 are respectively attached to the support roller 6 and the mounting column 7.

[0045] Specifically, the outer surface of the mounting rod 3 has two linearly arrayed insertion holes 20, and a pin 21 is inserted into each insertion hole 20. The exposed ends of both pins 21 are fixedly connected to limiting plates 22, which respectively abut against the support roller 6 and the mounting column 7. Thus, the mating structure of the insertion holes 20 and pins 21 enables rapid positioning and limiting of the support roller 6 and the mounting column 7; that is, the double-sided fitting design of the limiting plates 22 effectively controls the axial movement of the support roller 6 and the mounting column 7.

[0046] In one example, locking holes 23 are provided on the outer surfaces of both the mounting post 7 and the mounting sleeve 5. The corresponding setting of the locking holes 23 enables the mounting post 7 and the mounting sleeve 5 to be finally fixed by additional locking components, which can improve the structural reliability after installation.

[0047] In one example, two symmetrically arranged reinforcing ribs 26 are fixedly connected to the side of the assembly ring 8 away from the first connecting ring 10. Both reinforcing ribs 26 are fixedly connected to the mounting rod 3. The design of the reinforcing ribs 26 can significantly enhance the rigidity of the connection between the assembly ring 8 and the mounting rod 3, prevent deformation under high load conditions, and extend the service life of the device.

[0048] To better understand the present invention, the working process of the mounting device for the support roller will be further explained below with reference to the accompanying drawings.

[0049] When using it, at least the following steps are required: 1) Slide the fork arm of the forklift 2 into the insertion slot 4 of the mounting rod 3, and tighten the second locking bolt 16 to make the mounting rod 3 and the fork arm securely connected.

[0050] 2) Slide the support roller 6 and the mounting column 7 along the mounting rod 3 to the working position, insert the pin 21 into the insertion hole 20, so that the limiting plate 22 fits the support roller 6 and the mounting column 7, and adjust the mounting column 7 to make it coincide with the axis of the mounting sleeve 5.

[0051] 3) Operate the forklift 2 to fine-tune its position so that the mounting post 7 is aligned with the mounting sleeve 5, and pull out the pin 21 to release the constraint of the limit plate 22.

[0052] 4) The rotating lead screw 12 pushes the top ring 15 through the drive ring 13 and the transmission rod 14, so that the mounting post 7 and the mounting sleeve 5 reach the optimal matching position.

[0053] Compared with the prior art, the mounting device for support rollers of the present invention has at least the following advantages: (1) The installation device of the present invention, through the cooperation of the mounting rod 3 with the fork arm of the forklift 2, can solve the safety hazards and accuracy problems of traditional support roller installation that rely on manual labor. The specific operation steps may include: sliding the mounting rod 3 to the fork arm of the forklift 2 through the insertion slot 4 and fixing it with the second locking bolt 16; sliding the support roller 6 along the mounting rod 3 until it is aligned with the mounting sleeve 5, and inserting the mounting post 7 into the mounting sleeve 5; fixing the first connecting ring 10 with the first locking bolt 9 to ensure that the mounting rod 3 and the mounting sleeve 5 are coaxial. The beneficial effects are: using the forklift 2 to provide stable support and avoiding the risks of manual operation; the coaxial design of the mounting rod 3 and the mounting sleeve 5 ensures installation accuracy and reduces repeated adjustments; the assembly ring 8 and the first locking bolt 9 form a rigid connection to prevent displacement during the installation process, which significantly improves installation efficiency and safety.

[0054] (2) The installation device of the present invention ensures the stability of the installation process through the dual locking mechanism of the second locking bolt 16 and the limiting plate 22. The specific operation steps may include: tightening the second locking bolt 16 so that its screw part is close to the fork arm part of the forklift 2, and firmly fixing the mounting rod 3; inserting the pin 21 so that the limiting plate 22 fits against the support roller 6 and the mounting column 7, limiting their axial displacement. The beneficial effects are: the second locking bolt 16 prevents the mounting rod 3 from accidentally disengaging from the fork arm part, ensuring the stability of the equipment; the limiting plate 22 achieves quick positioning through the pin 21, avoiding the support roller 6 from shaking or tilting during the installation and adjustment process, ensuring that the mounting column 7 and the mounting sleeve 5 are accurately aligned, and reducing the risk of wear on the bearing mating surface.

[0055] (3) The installation device of the present invention uses a drive mechanism with a lead screw 12 to achieve labor-saving installation of the support roller 6. The specific operation steps may include: during installation, pulling out the pin 21 to release the limit, rotating the lead screw 12 to drive the drive ring 13 to move, and pushing the top ring 15 against the support roller 6 and the mounting post 7 through the transmission rod 14, so as to smoothly push it out of the mounting rod 3. The beneficial effects are: the lead screw 12, through the force amplification effect of the drive ring 13 and the transmission rod 14, makes the top ring 15 generate a uniform thrust, avoiding damage to the parts caused by manual knocking; the guide hole 19 ensures the linear movement of the transmission rod 14, and the full contact between the top ring 15 and the support roller 6 prevents local stress concentration, so as to achieve safe and labor-saving installation of the heavy support roller 6 and greatly reduce labor intensity.

[0056] Although the invention has been described with reference to preferred embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention.
