Abstract
Description
Technical Field
[0001] This application belongs to the field of engineering machinery technology, specifically relating to a swing frame and an all-terrain tire crane. Background Art
[0002] The swing frame of an off-road tire crane is a crucial device connecting the chassis and axle. When the axle lacks suspension cylinder supports, the suspension cylinders must also be connected to the swing frame. Furthermore, to meet off-road driving requirements, it's essential to ensure the wheels connected to the axle maintain good contact with the ground throughout the journey. Therefore, the axle must be allowed to swing a certain angle around the chassis's swing center, following the swing frame. Simultaneously, to prevent excessive swing angles exceeding the suspension cylinder's stroke, limit blocks must be installed on both sides of the swing frame. Once the specified angle is reached, the limit blocks abut against the workshop floor cover to achieve the desired stop.
[0003] However, existing common swing frames are integral welded parts. When the axle is different or the swing frame limit angle requirement is different, the swing frame cannot be universal and needs to be redesigned. Summary of the Invention
[0004] The purpose of this application is to provide a swing frame and an all-terrain tire crane to improve the versatility of the swing frame.
[0005] To achieve the above objectives, this application provides a swing frame, which includes:
[0006] The swing frame body is provided with a swing center hole for hinged mounting to the frame;
[0007] The horizontal mounting plate and the vertical mounting plate are set perpendicularly to each other at the ends of the swing frame body and can be used to detachably install the limit seat.
[0008] In some embodiments, the horizontal mounting plate is provided with a plurality of vertical through-connecting holes, and the vertical mounting plate is provided with a plurality of horizontal through-connecting holes.
[0009] In some embodiments, the limiting seat includes:
[0010] The base plate has several vertical mounting holes that are aligned with several vertical through-holes.
[0011] A vertical plate, extending upwards from the base plate, has several horizontal mounting holes aligned with several horizontally penetrating connecting holes; and
[0012] The top plate extends laterally from the top of the vertical plate and is used to abut and limit the movement.
[0013] In some embodiments, the limiting seat includes:
[0014] Several vertical support plates are set between the bottom plate and the top plate to support the top plate.
[0015] In some embodiments, the limiting seat includes:
[0016] Fastening components are used to connect vertical through holes and vertical mounting holes, as well as to connect horizontal through holes and horizontal mounting holes.
[0017] In some embodiments, the swing frame further includes:
[0018] The suspension cylinder lugs extend laterally outward from the vertical plate of the limit seat.
[0019] In some embodiments, the suspension cylinder lug plate and the limiting seat are formed as a welded integral part, or the suspension cylinder lug plate and the limiting seat are detachable and installable.
[0020] In some embodiments, the swing frame includes:
[0021] Support ribs are installed on the horizontal mounting plate and are used to laterally support the vertical mounting plate.
[0022] The second aspect of this application protects an off-road tire crane, including an axle and a frame. The off-road tire crane includes the aforementioned swing frame, the end of which is connected to the frame and hinged to the axle through a swing center hole.
[0023] The third aspect of this application protects an off-road tire crane, including an axle and a frame. The off-road tire crane also includes a limit seat and the aforementioned swing frame. The limit seat is mounted on the frame bottom cover plate of the frame, and the end of the swing frame body is connected to the frame and hinged to the axle through a swing center hole.
[0024] In the technical solution of this application, since the swing frame body is pivotally mounted on the vehicle frame, and the end of the swing frame body is provided with a transverse mounting plate and a vertical mounting plate, each including several vertical through-holes and transverse through-holes, after the swing frame undergoes a pivoting movement, as an example, a limiting seat can be detachably installed above the end of the swing frame body through several vertical or transverse through-holes. After the limiting seat abuts against the vehicle frame, the swing frame is limited, thereby ensuring that the swing frame will not exceed the stroke of the suspension cylinder due to excessive swing angle. When the limiting seat is detachably installed on the swing frame, compared with the swing frame of the prior art that is an integral welded part, the swing frame of this application can easily realize the replacement of limiting seats of different sizes, thereby realizing different swing angle limits, and thus realizing the matching of different specifications of axles connected to the swing frame.
[0025] Other features and advantages of the embodiments of the present application will be described in detail in the subsequent detailed description. Attached Figure Description

[0044] The following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not intended to limit the present application.
[0045] The swing frame and all-terrain tire crane according to this application are described below with reference to the accompanying drawings.
[0046] It should be noted that, in this application, unless otherwise stated, terms such as "upper," "lower," "front," "rear," "inner," and "outer" generally refer to the orientation shown in the accompanying drawings. When no accompanying drawings are provided, "inner" and "outer" refer to the lateral inward or outward relative to the central axis of the swing center hole 301.
[0047] This application discloses a novel swing frame, such as Figure 1 As shown, the swing frame in one specific embodiment includes:
[0048] The swing frame body 300 is provided with a swing center hole 301 for hinged installation to the frame 200;
[0049] The horizontal mounting plate 310 and the vertical mounting plate 320 are perpendicularly arranged at the ends of the swing frame body 300 and can be used to detachably mount the limit seat 100.
[0050] Specifically, see Figure 1 Since the swing frame body 300 can be hinged to the frame 200 through the swing center hole 301, the swing frame can pivot relative to the swing center hole 301. Therefore, as an example, when the transverse mounting plate 310 has several vertical through-connecting holes 311 and the vertical mounting plate 320 has several transverse through-connecting holes 321, the end of the swing frame body 300 can be detachably installed with a limiting abutment (i.e., a limiting seat 100) for abutting against the frame 200. After the swing frame pivots at a certain angle, the limiting abutment can abut against the frame 200 before the swing frame body 300, thereby limiting the swing angle of the swing frame and ensuring that the swing angle of the swing frame is within a certain range. As an example, when a suspension cylinder 400 is provided between the axle 500 connected to the swing frame and the frame 200, the swing range of the swing frame will not exceed the stroke of the suspension cylinder 400. Compared to the existing technology where the limiting abutment and the swing frame body 300 are welded together, the limiting abutment on the swing frame of this application is more convenient to disassemble and assemble, and can meet the different swing angle requirements of different specifications of axles 500. It is not only simple in structure and more economical, but also highly practical.
[0051] In this embodiment, if Figure 2 As shown, the horizontal mounting plate 310 is provided with a number of vertical through-connection holes 311, and the vertical mounting plate 320 is provided with a number of horizontal through-connection holes 321.
[0052] This arrangement facilitates the reinforcement of the stability of the limit seat 100 at the end of the swing frame body 300 by fasteners that pass through the vertical through connection hole 311 and the horizontal through connection hole 321 respectively.
[0053] The aforementioned limiting and abutting member can take many forms. Specifically, in this embodiment, such as... Figures 2 to 4 As shown, the limiting seat 100 includes:
[0054] The base plate 111 is provided with a plurality of vertical mounting holes 111a for aligning one-to-one with a plurality of vertical through-connection holes 311;
[0055] A vertical plate 112 extends upward from a base plate 111 and has a plurality of horizontal mounting holes 112a for alignment with a plurality of horizontally through-holes 321; and
[0056] The top plate 120 extends laterally from the top of the vertical plate 112 and is used to abut against the limit.
[0057] Specifically, the base plate 111 is fastened to the horizontal mounting plate 310 of the swing frame body 300 by fasteners that pass through the vertical through connection hole 311 and the vertical mounting hole 111a, and the vertical plate 112 is fastened to the vertical mounting plate 320 of the swing frame body 300 by fasteners that pass through the horizontal through connection hole 321 and the horizontal mounting hole 112a. With this configuration, the limiting seat 100 can be accurately, securely and detachably positioned at the end of the swing frame body 300, and abutted against the frame 200 by the top plate 120.
[0058] The top plate 120 can be welded to the top of the vertical plate 112, or it can be detachably connected to the top of the vertical plate 112.
[0059] During the vehicle's journey, it may encounter significant bumps, resulting in a substantial impact load on the limiting seat 100. Therefore, while ensuring the limiting seat 100 is detachable and installable, its structural strength must also be guaranteed. In this embodiment, as... Figure 3 As shown, the limiting seat 100 includes:
[0060] Several vertical support plates 113 are arranged between the bottom plate 111 and the top plate 120 to support the top plate 120.
[0061] Specifically, several vertical support plates 113 are connected at one end to the base plate 111, and at the other end extend upward to support the top plate 120. This arrangement greatly enhances the structural strength of the limiting seat 100, thereby ensuring the limiting capability of the swing frame.
[0062] In some embodiments, the limiting seat 100 includes:
[0063] Fastening assembly 130 is used to connect the vertical through connection hole 311 and the vertical mounting hole 111a, and to connect the horizontal through connection hole 321 and the horizontal mounting hole 112a.
[0064] Specifically, see Figure 3 The fasteners include elastic washers, flat washers, nuts, and bolts. The base plate 111 is fastened to the horizontal mounting plate 310 of the swing frame body 300 by bolts passing through the vertical through-hole 311 and the vertical mounting hole 111a. The vertical plate 112 is fastened to the vertical mounting plate 320 of the swing frame body 300 by bolts passing through the horizontal through-hole 321 and the horizontal mounting hole 112a. Flat washers are placed between the nuts and the base plate 111 and the vertical plate 112, and elastic washers are placed between the bolt heads and the base plate 111 and the vertical plate 112. This arrangement improves the stability of the limit seat 100 on the swing frame body 300.
[0065] When the axle 500 does not have a support for the suspension cylinder 400, the suspension cylinder 400 also needs to be connected to the swing frame. In this embodiment, the swing frame further includes:
[0066] The suspension cylinder ear plate 140 extends laterally outward from the vertical plate 112 of the limit seat 100.
[0067] Specifically, see Figure 4 and Figure 5 One end of the suspension cylinder ear plate 140 is connected to the limiting seat 100, and the other end extends laterally outward and is hinged to the suspension cylinder 400. The other end of the suspension cylinder 400 is hinged to the frame 200. With this configuration, the suspension cylinder 400 can be positioned between the swing frame and the frame 200, thereby significantly mitigating the impact of vibration and other factors on the swing frame.
[0068] In this embodiment, the suspension cylinder ear plate 140 and the limiting seat 100 are formed as a welded integral part, or the suspension cylinder ear plate 140 and the limiting seat 100 can be detachably installed.
[0069] Specifically, see Figure 3 and Figure 4The suspension cylinder ear plate 140 can be formed by extending outward from the vertical support plate 113 which is welded to the limit seat 100, or it can be detachably installed as an independent part with the limit seat 100. For example, the suspension cylinder ear plate 140 is fastened to the vertical support plate 113 by ear plate fasteners that pass through the mounting holes of the suspension cylinder ear plate 140 and the mounting holes of the vertical support plate 113.
[0070] In this embodiment, if Figure 2 As shown, the swing frame includes:
[0071] Support rib 330 is disposed on the horizontal mounting plate 310 and is used to laterally support the vertical mounting plate 320.
[0072] Specifically, see Figure 2 This design helps to strengthen the connection between the vertical mounting plate 320 and the horizontal mounting plate 310, and the structure is simple and practical.
[0073] This application also protects an off-road tire crane, including an axle 500 and a frame 200. In one specific embodiment, the off-road tire crane includes the aforementioned swing frame. The end of the swing frame body 300 is connected to the frame 200 and hinged to the axle 500 through a swing center hole 301.
[0074] Specifically, this all-terrain tire crane possesses all the technical effects brought about by the aforementioned swing frame, and therefore will not be elaborated upon here. The tires of the all-terrain tire crane are connected to the axle 500, the axle 500 is fixedly connected to the swing frame, and the swing frame is hinged to the frame 200. See [link / reference] Figure 4 As an example, when an off-road tire crane encounters a bump, the left wheel of the off-road tire crane lifts, that is, the axle 500 swings clockwise. At the same time, the axle 500 will drive the swing frame to pivot clockwise relative to the swing center hole 301. After a certain pivot angle, such as Figure 4 As shown, at this time, the top plate 120 of the limiting seat 100 and the bottom cover plate 210 of the frame 200 abut against each other, thereby realizing the limiting of the swing frame.
[0075] It should be noted that when the limit seat 100 includes the suspension cylinder ear plate 140, the suspension cylinder 400 is not as... Figure 4 It is connected to axle 500 as shown, but as... Figure 5 The suspension cylinder lug 140 is shown as hinged.
[0076] This application also protects an off-road tire crane, including an axle 500 and a frame 200. In one embodiment, the off-road tire crane further includes a limit seat 100 and the aforementioned swing frame. The limit seat 100 is mounted on the frame bottom cover plate 210 of the frame 200, and the end of the swing frame body 300 is connected to the frame 200 and hinged to the axle 500 through the swing center hole 301.
[0077] Specifically, the limiting seat 100 is fastened to the underside of the frame bottom cover plate 210 of the frame 200 by a bottom cover plate fastener that passes through the vertical mounting hole 111a and the mounting hole of the frame bottom cover plate 210, and is limited by abutting against the upper end surface of the swing frame body 300 (such as the transverse mounting plate 310) through the top plate 120. This configuration improves the flexibility, adaptability and practicality of the limiting seat 100 of the all-terrain crane.
[0078] It should be noted that at this time, the suspension cylinder 400 should be configured to be hinged to the axle 500 at one end and hinged to the frame 200 at the other end.
