Description

Technical Field

[0001] This utility model relates to the field of transport trailer technology, specifically an adjustable center-axle vehicle transport trailer support column. Background Technology

[0002] In the automotive logistics and transportation sector, center-axle vehicle transport trailers have become core equipment for long-distance transport of multiple vehicles due to their flexible loading layout and high space utilization. Their core design logic lies in doubling transport capacity through a "double-layer platform" structure. The uprights, as key load-bearing components connecting the trailer frame and the second-layer platform, directly determine the load-bearing safety, height adjustment flexibility, and operating space utilization of the second-layer platform, making them a core component affecting the overall performance of the trailer.

[0003] However, existing adjustable center-axle vehicle transport trailer uprights typically use mechanical pin-type uprights. Since the positioning holes are pre-machined, the spacing between adjacent holes is usually fixed, which means that the upright length adjustment can only switch between fixed gears and cannot achieve continuous stepless adjustment, thus reducing its applicability. Utility Model Content

A number of rollers are rotatably connected inside the concave plate, and the rollers are in contact with the sliding groove.

[0011] Preferably, rotating rods are fixedly installed on both sides of the hinge plate, and the rotating rods are rotatably connected to the hinge seat.

[0021] 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.

[0022] Example 1

[0023] This embodiment aims to address the issue that column length adjustment can only switch between fixed positions and cannot achieve continuous stepless adjustment. Please refer to [link / reference]. Figures 1-4 An adjustable center-axle vehicle transport trailer support column includes a vehicle body 1 and lifting platforms 2 fixed on both sides of the vehicle body 1. A platform 3 is installed on one side of the lifting platform 2, which can also lift the platform 3. The lifting platform 2 is existing technology and will not be described in detail here. Drive seats 4 are fixedly installed on both sides of the vehicle body 1, and a fixed frame 5 is provided on one side of the drive seat 4. A hydraulic cylinder 6 is hinged inside the fixed frame 5. Through the lifting and telescopic design of the hydraulic cylinder 6, the adjustment accuracy, load-bearing capacity, and strength are far superior to traditional columns. At the same time, it does not occupy the space of the second-level platform 3, giving the second-level platform 3 a larger working area. A support frame 7 is slidably connected to one end of the fixed frame 5, and the support frame 7 is slidably connected to the platform 3. When the platform 3 is in the retracted or initial height position, the support frame 7 is retracted inside the fixed frame 5. The overall structure is compact and does not occupy extra space. The output end of the hydraulic cylinder 6 is fixedly connected to the support frame 7.

[0024] When the height of platform 3 needs to be adjusted to adapt to the loading, unloading, or transportation needs of different vehicles, drive seat 4 provides power support, hydraulic cylinder 6 is activated, and the output end of hydraulic cylinder 6 extends, pushing support frame 7 to slide along the inside of fixed frame 5 and extend outward. Since support frame 7 is slidably connected to platform 3, platform 3 is lifted under the pushing action of support frame 7, realizing the height adjustment. When it is necessary to lower the height of platform 3, the output end of hydraulic cylinder 6 retracts, pulling support frame 7 back into fixed frame 5. Platform 3 descends under its own weight and the pulling action of support frame 7, returning to the required height position. During the entire adjustment process, with the sliding connection between support frame 7 and platform 3 and the support and positioning of fixed frame 5, the support points of the column on platform 3 can be flexibly adjusted according to the actual size and position requirements of the vehicle, ensuring that platform 3 stably supports the vehicle. The lifting and telescopic design of hydraulic cylinder 6, compared with the traditional mechanical pin-type adjustment, can achieve stepless adjustment and precisely control the height of platform 3 to meet the precise requirements of different vehicle models for load-bearing height, especially avoiding pressure or damage to sensitive components such as the battery pack of new energy vehicle chassis.

[0025] The hydraulic cylinder 6 drive and the cooperative structure of the fixed frame 5 and support frame 7 make the overall load-bearing capacity and structural strength of the column far superior to traditional columns. It can stably bear the weight of various vehicles and is not prone to deformation or damage during transportation, thus improving transportation safety. The column structure is reasonably designed, with core components such as the hydraulic cylinder 6 integrated inside the fixed frame 5, without occupying the space of the second-level platform 3. This allows the second-level platform 3 to have a larger working area, facilitating vehicle loading and unloading operations and flexible placement of multiple vehicle types. The hydraulic cylinder 6 enables automated lifting and extension adjustment, which is simpler and faster than the traditional manual adjustment method, saving loading and unloading time and improving the efficiency of transportation operations. The fixed frame 5 can be moved and its position adjusted through the drive seat 4, allowing precise alignment of the support point of the platform 3 with the center of gravity of the vehicle. When transporting vehicles with mixed vehicle types or offset centers of gravity, it completely solves the problem of local overload caused by the non-adjustable position of traditional fixed columns, extending the structural life of the vehicle body 1 and platform 3.

[0026] In this embodiment: a strip plate 31 is fixedly installed on both sides of the bottom of the platform 3, a slide plate 32 is fixedly installed on one side of the strip plate 31, and a slide groove 33 is opened on both sides of the slide plate 32. The drive seat 4 includes a base plate 41 and a frame plate 42 fixed on one side of the base plate 41. A screw 43 is rotatably connected inside the frame plate 42. A handwheel 44 is fixedly installed at one end of the screw 43. By rotating the handwheel 44, the screw 43 can be driven to rotate, which can play an adjustment role.

[0027] The fixing frame 5 includes a fixing plate 51 and two first columns 52 fixed to one side of the fixing plate 51. Each of the two first columns 52 has a fixing frame 53 installed on its surface. The first columns 52 can play a limiting role. A screw plate 511 is fixedly installed on one side of the fixing plate 51. The screw plate 511 is threadedly connected to the screw rod 43 and slidably connected to the frame plate 42. By turning the handwheel 44, the screw rod 43 can be driven to rotate. The rotation of the screw rod 43 can drive the screw plate 511 to move, thereby adjusting the position of the fixing plate 51.

[0028] The support frame 7 includes two second columns 71 and a hinge seat 72 fixed to one end of the two second columns 71. Both second columns 71 are slidably connected to the two first columns 52. A hinge plate 73 is rotatably mounted on one side of the hinge seat 72, and a concave plate 74 is fixedly mounted on one side of the hinge plate 73. Several rollers 75 are rotatably connected inside the concave plate 74. The rollers 75 contact the slide groove 33. Through the rolling contact between the rollers 75 and the slide groove 33, the frictional resistance between the support frame 7 and the platform 3 is greatly reduced compared with the traditional sliding contact method. This makes the lifting and adjustment of the platform 3 smoother, reduces the driving load of the hydraulic cylinder 6, reduces energy loss, and also reduces the wear of components and extends service life.

[0029] Rotating rods 731 are fixedly installed on both sides of the hinge plate 73. The rotating rods 731 are rotatably connected to the hinge seat 72, and the rotating rods 731 can play a connecting role.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
