Description

Technical Field

[0001] This utility model relates to the field of manufacturing and assembly technology, and in particular to a portable installation tool. Background Technology

[0002] In the production and assembly process of rail transit equipment, the assembly quality of bogie wheels directly affects the safety and stability of train operation. As a key load-bearing component of the bogie, the installation process of the split-type swing arm axle box involves the precise matching and connection of two core components: the swing arm and the swing arm hoist. The traditional assembly process employs a two-person collaborative operation mode: first, the swing arm is hoisted to the wheel axle end for positioning and adjustment using a single-beam bridge hoisting device; then, another operator must manually support the swing arm hoist assembly throughout the process, maintaining three-dimensional spatial stability while aligning and pre-tightening the bolt holes with the swing arm.

[0003] The above-mentioned process has significant technical bottlenecks: manual lifting operations are not only labor-intensive and pose safety hazards, but also prone to fluctuations in assembly accuracy due to prolonged heavy-duty operation; differences in the rhythm of two people working together can easily lead to waiting in the process, low installation efficiency, and affect the production line cycle time. Furthermore, people will experience fatigue under long-term working conditions, which poses safety hazards. Utility Model Content

[0008] In some embodiments, the support frame is a cubic frame composed of multiple metal rods.

[0009] In some embodiments, the four vertically arranged edges of the cube frame are made of angle steel.

[0010] In some embodiments, the angle steel opening side is oriented toward the central axis of the cube frame, and the movable seat has four vertically arranged sliding rods that slide in cooperation with the angle steel opening side, so that the movable seat can be slidably mounted on the support frame along the vertical direction.

[0011] In some embodiments, a reinforcing member is horizontally arranged at the top of the cube frame, the reinforcing member having an opening, and a vertically extending support rod is fixedly connected inside the movable seat. One end of the support rod can pass through the opening from above the reinforcing member to below the reinforcing member. The locking assembly can lock the support rod to the reinforcing member so that the locking assembly locks the movable seat after it has been moved to a usable position.

[0012] In some embodiments, at least a portion of the support rod is provided with threads, and the locking assembly includes a locking nut and a positioning nut. The locking nut is located above the reinforcing member, and the threads are located below the reinforcing member. Both the locking nut and the positioning nut are connected to the threads on the support rod. When the movable seat moves to the use position, the locking nut moves downward to abut against the upper surface of the reinforcing member, and the positioning nut moves upward to abut against the lower surface of the reinforcing member to lock the use position of the movable seat.

[0013] In some embodiments, the support rod is a screw.

[0014] In some implementations, the movable component is a caster wheel with a locking function.

[0015] In some embodiments, the casters are attached to the bottom of the support frame via a detachable bolt assembly.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The purpose of this utility model is to provide a portable installation tool to solve the problems existing in the prior art, reduce the difficulty of installation operations, improve installation efficiency, reduce safety hazards and enhance portability.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Combination Figures 1 to 3This utility model provides a portable installation fixture, including a support frame 2, a movable seat 1, a locking component 3, and a moving component; the movable seat 1 is slidably mounted on the support frame 2 along the vertical direction, and the movable seat 1 is provided with a support part 12 for supporting the workpiece and a limiting part 11 for restricting the rotational freedom of the workpiece on the support part 12; the locking component 3 is used to lock the movable seat 1 after it has been moved to a usable position; the moving component is installed at the bottom of the support frame 2 for moving the support frame 2.

[0027] The "usable position" refers to the position that supports the workpiece to the height required for the assembly step. It is understood that the height of the usable position may be different for different workpieces or different installation steps. When the portable installation fixture is used to assemble the swing arm axle box, the usable position specifically refers to the horizontal height of the movable seat 1 from the ground being 1.2 meters. In addition, the horizontal height of the movable seat 1 from the ground can be adjusted according to the actual use.

[0028] The portable installation fixture provided in this embodiment uses the swing arm axle box as the specific assembly workpiece, abandoning the traditional manual lifting installation method. The swing arm axle box is placed on the movable seat 1 for installation. In actual operation, the installation fixture needs to be placed directly below the swing arm axle box. After the movable seat 1 is moved to the usable position, the position of the movable seat 1 is fixed by the locking component 3. At the same time, the movable seat 1 also includes a support part 12 that can support the swing arm axle box and a limiting part 11 that can limit the rotational freedom of the swing arm axle box on the support part 12, effectively ensuring its absolute stability during subsequent assembly operations. After completing the above fixture positioning and fixing process, the swing arm axle box to be assembled is placed stably on the support part 12 of the installation fixture using professional lifting tools. The support part 12 can support the swing arm axle box and limit the rotational freedom of the swing arm axle box on the support part 12. Then, the precision assembly operation of the swing arm axle box can be carried out according to the predetermined assembly process.

[0029] Therefore, this embodiment reduces the difficulty of installing the split-type swing arm axle box, improves the installation efficiency of the split-type swing arm axle box, and reduces the safety hazards that exist during the installation process.

[0030] Furthermore, the lifting method of the movable seat 1 provided in this embodiment is manual lifting, which aims to simplify the tooling structure, facilitate carrying, and reduce production and manufacturing costs. In some examples, the movable seat 1 can also be moved by electric drive.

[0031] In some embodiments, the support part 12 is a support surface disposed on the top of the movable seat 1, and the limiting part 11 is a limiting surface disposed on the side of the support surface. In use, the limiting surface extends vertically upward and the support surface extends horizontally.

[0032] This embodiment provides a specific structure for the support portion 12, such as... Figure 3 As shown, it is understandable that the support surface and the limiting surface are set perpendicular to each other.

[0033] In some embodiments, the support frame 2 is a cubic frame composed of multiple metal rods.

[0034] In some embodiments, the four vertically arranged edges of the cube frame are angle steel 22.

[0035] In this embodiment, angle steel 22 is used as the main structure of the cube frame. Angle steel 22 has good compressive and bending strength and can withstand large loads, so that it can effectively support heavy objects in the supporting structure and ensure the stability and safety of the structure.

[0036] In some embodiments, the opening side of the angle steel 22 is oriented toward the central axis of the cube frame, and the movable seat 1 has four vertically arranged slide rods 13. The slide rods 13 slide in cooperation with the opening side of the angle steel 22 so that the movable seat 1 can be slidably mounted on the support frame 2 along the vertical direction.

[0037] In this embodiment, the angle steel 22 is positioned with its open side facing the central axis of the cube frame. Combined with the cooperation of the movable seat 1 and the slide rod 13, the weight of the device can be reduced, achieving a lightweight design and facilitating the movement of the device. In some examples, an airbag-type slide can also be used.

[0038] In some embodiments, a reinforcing member 21 is horizontally arranged on the top of the cube frame. The reinforcing member 21 has an opening. A vertically extending support rod 4 is fixedly connected inside the movable seat 1. One end of the support rod 4 can pass through the opening from above the reinforcing member 21 to below the reinforcing member 21. The locking component 3 can lock the support rod 4 onto the reinforcing member 21 so that the movable seat 1 can be moved to a usable position and then locked by the locking component 3.

[0039] In this embodiment, a reinforcing member 21 is horizontally provided at the top of the cubic frame. On the one hand, it can strengthen the stability of the entire frame structure. On the other hand, it can work with the locking component 3 to lock the support rod 4 onto the reinforcing member 21 so that the locking component 3 can lock the movable seat 1 after it is moved to a usable position.

[0040] In some embodiments, at least a portion of the support rod 4 is provided with threads, and the locking assembly 3 includes a locking nut 31 and a positioning nut 32. The locking nut 31 is located above the reinforcing member 21, and the threads are located below the reinforcing member 21. Both the locking nut 31 and the positioning nut 32 are connected to the threads on the support rod 4. When the movable seat 1 moves to the use position, the locking nut 31 moves downward to abut against the upper surface of the reinforcing member 21, and the positioning nut 32 moves upward to abut against the lower surface of the reinforcing member 21 to lock the use position of the movable seat 1.

[0041] This embodiment provides a locking method in which the moving seat 1 is locked by rotating the locking nut 31 and the positioning nut 32 on the support rod 4 and tightening the reinforcing member 21. This locking method is simple, feasible and stable. Understandably, in some examples, the moving seat 1 is also locked by setting several transverse through holes on the support rod 4 and using a pin to abut against the reinforcing member 21.

[0042] In some embodiments, the support rod 4 is a screw.

[0043] This embodiment uses a screw as the support rod 4, which has a simple structure and can be applied directly without secondary processing. Alternatively, the screw can be omitted, and only a section of thread can be provided on the support rod 4, while the rest is not threaded. This also allows the locking nut 31 and the positioning nut 32 to move on the support rod 4 and lock the position of the moving seat 1.

[0044] In some embodiments, the moving component is a swivel wheel 5 with a locking function.

[0045] This embodiment uses a swivel wheel 5 with a locking function as a moving component. This swivel wheel 5 combines the flexibility of movement with the stability of fixation. When the mobile device needs to be moved, the swivel wheel 5 can roll and turn freely, making it easy to adjust its position. When it reaches its destination, it can be quickly fixed in place by locking, meeting the usage needs of different scenarios.

[0046] In some embodiments, the caster wheel 5 is attached to the bottom of the support frame 2 by a detachable bolt assembly.

[0047] This embodiment provides an installation structure for a caster wheel 5, which is assembled using a detachable bolt assembly. This facilitates the replacement of wheel bodies made of different materials to adapt to installation processes in different environments. In some examples, installation methods other than detachable bolt assemblies can also be used, such as welding and riveting, all of which are within the scope of protection of this application. Specific examples have been used in this utility model to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core ideas of this utility model; at the same time, for those skilled in the art, there will be changes in specific implementation methods and application scope based on the ideas of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
