Description

Technical Field

[0001] The utility model relates to the field of rail flatbed vehicles, in particular to a rail flatbed vehicle device with a lifting function. Background Art

[0002] During the construction of high-speed rail and urban rail transit, sound barriers are often installed on high-speed rail or urban rail near residential areas to reduce noise pollution. The installation of steel columns, steel curved beams and screen bodies involved in the installation of sound barriers are all high-altitude operations, and generally a scaffolding installation platform needs to be built on the section line to install the sound barriers.

[0003] Referring to the comparative document, the publication number is CN218088853U, the utility model relates to a rail flatbed vehicle device with a lifting function, comprising a flatbed vehicle body and at least one lifting platform mechanism installed on the top of the flatbed vehicle body; the bottom of the flatbed vehicle body is equipped with rail wheels compatible with the rail, and each of the lifting platform mechanisms comprises a base, a lifting assembly and a working platform; the base is installed on the top of the flatbed vehicle body; the working platform is arranged above the base; the bottom of the lifting assembly is connected to the base, and the top is connected to the working platform, which is used to drive the working platform to rise or fall; the utility model can adapt to the installation and construction of sound barriers of different heights by arranging several lifting platform mechanisms on the top of the flatbed vehicle body, thereby reducing the platform construction time and greatly improving the construction efficiency. In addition, when encountering obstacles, the working platform can be lowered to reduce the occupied space, thereby effectively avoiding the obstacles.

[0004] Although the comparative document can perform lifting operations through lifting components, the comparative document lacks shock-absorbing devices. During the mobile transportation process of the rail flatbed truck, for example, when turning, if a specially designed turning track is not used or an appropriate turning method is not adopted, the flatbed truck may vibrate due to insufficient stability. If it is not shock-absorbing, the vibration will be transmitted to the lifting platform through the flatbed truck, causing the lifting platform to vibrate, which will affect the structural stability of the platform and may even cause damage to the cargo or safety risks to the operator. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a rail flatbed vehicle device with a lifting function, aiming to improve the problem that the existing rail flatbed vehicles lack a shock absorbing device.

[0006] The utility model is achieved in this way:

[0007] The utility model provides a rail flatbed vehicle device with a lifting function, comprising a flatbed vehicle body, a working platform being arranged at the upper end of the flatbed vehicle body, side panels being fixedly connected to both sides of the flatbed vehicle body, dampers being fixedly connected to both sides of the side panels, the upper ends of the dampers being connected to the working platform, mounting members being fixedly connected to both sides of the side panels, a connecting rod being fixedly connected between the two mounting members, extrusion members being slidably arranged on both sides of the connecting rod, and a shock-absorbing stabilizing mechanism being arranged on the extrusion members.

[0008] Preferably, the shock-absorbing and stabilizing mechanism includes a swing arm rotatably connected to the extrusion piece, a mounting protrusion is fixedly connected to the lower end of the working platform, and one end of the swing arm away from the extrusion piece is rotatably connected to the outer side wall of the mounting protrusion.

[0009] Preferably, shock-absorbing springs are sleeved on both sides of the connecting rod, one end of the shock-absorbing spring is in contact with the extrusion piece, and the other end away from the extrusion piece is in contact with the mounting piece.

[0010] Preferably, a lifter is installed on the upper end of the working platform, and a support platform is installed on the top of the lifter.

[0011] Preferably, a fence is installed on the outer side wall of the support platform, and a flip door is provided on the fence.

[0012] Preferably, both the front and rear sides of the working platform are rotatably connected with track wheels.

[0013] The beneficial effects of the utility model are:

[0014] By setting up mechanisms such as shock-absorbing springs and dampers, it can be achieved that when the entire flatbed truck body is moved, the shock-absorbing springs and dampers can, with the cooperation of their own elastic force, buffer and consume the vibration generated by the flatbed truck body, thereby preventing the vibration from being transmitted to the platform and affecting the stability of the platform. When the flatbed truck body is moved to the designated installation position, the operator can stand on the platform and install sound barriers of different heights by lifting the lifter, making the entire device more efficient and flexible to use.

[0021] Example

[0022] Reference Figure 1-3 A rail flatbed vehicle device with a lifting function comprises a flatbed vehicle body 1, a working platform 102 is arranged on the upper end of the flatbed vehicle body 1, and the front and rear sides of the working platform 102 are rotatably connected with rail wheels 101, a lifter 2 is installed on the upper end of the working platform 102, a support platform 203 is installed on the top of the lifter 2, a fence 201 is installed on the outer side wall of the support platform 203, and a flip door 202 is arranged on the fence 201, and side panels 103 are fixedly connected to both sides of the flatbed vehicle body 1, and dampers 108 are fixedly connected to both sides of the side panels 103;

[0023] Furthermore, the upper end of the damper 108 is connected to the working platform 102, and mounting parts 104 are fixedly connected to both sides of the side plate 103, and a connecting rod 105 is fixedly connected between the two mounting parts 104. Shock-absorbing springs 107 are sleeved on both sides of the connecting rod 105, one end of the shock-absorbing spring 107 is in contact with the extrusion part 106, and the end away from the extrusion part 106 is in contact with the mounting part 104, and extrusion parts 106 are slidably arranged on both sides of the connecting rod 105. A shock-absorbing stabilization mechanism is arranged on the extrusion part 106, and the shock-absorbing stabilization mechanism includes a swing arm 109 rotatably connected to the extrusion part 106. A mounting protrusion 110 is fixedly connected to the lower end of the working platform 102, and the end of the swing arm 109 away from the extrusion part 106 is rotatably connected to the outer wall of the mounting protrusion 110.

[0024] The working principle of this rail flatbed vehicle device with lifting function:

[0025] When in use, the operator can first move and transport the entire flatbed vehicle body 1 through the multiple track wheels 101 at the bottom of the flatbed vehicle body 1. During the movement and transportation of the flatbed vehicle body 1, if the flatbed vehicle body 1 vibrates, the working platform 102 will move up and down on the flatbed vehicle body 1. At this time, the pressure generated by the vibration will be applied to the swing arm 109, so that the two swing arms 109 will flip to the two sides of the connecting rod 105, pushing the extrusion piece 106 to squeeze the shock-absorbing spring 107, so that the shock-absorbing spring 107 will shrink. Since the shock-absorbing spring 107 itself has elastic force, the shock-absorbing spring 107 can rely on its own elastic force to move the working platform 102 up and down. The vibration generated is consumed and buffered to achieve the effect of shock absorption. While the shock-absorbing spring 107 absorbs shock, the dampers 108 located on both sides of the side plate 103 can also rely on their own elastic force to absorb and buffer the bumps generated by the working platform 102, thereby preventing the working platform 102 from transmitting vibration to the lifter 2, causing the platform 203 to vibrate and affecting the installation and use of the platform 203. When the flatbed truck body 1 moves to the designated installation position, the operator can stand on the platform 203 and realize the installation and construction of sound barriers of different heights by lifting the lifter 2, making the entire device more efficient to use (this is the prior art and will not be elaborated on in detail).

[0026] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0027] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
