Description

Technical Field

[0001] The utility model is designed in the technical field of hydropower station equipment transportation, and in particular relates to a platform transportation device for load equipment. Background Art

[0002] The routine maintenance and overhaul of hydropower stations involves the transfer of some equipment. In some cases, because there is no lifting equipment between the starting point and the end point of the transfer, we use a platform transfer vehicle for the transfer.

[0003] However, when using a platform transfer vehicle for transfer, there are obstacles on the ground that affect the platform transfer vehicle's passage, such as ground pipelines, speed bumps, etc. In order to solve this problem, we have improved the existing platform transfer vehicle.

[0004] After searching, although the Chinese patent document CN204641430U, published (announcement) date: 2015.09.16, discloses a load-carrying electric flatbed truck with an obstacle detection function, this flatbed truck only has the ability to detect obstacles in front of it and cannot cross obstacles on the ground.

[0005] For another example, Chinese patent document CN221367159U, published (announced) on July 19, 2024, discloses a hand-pushed flatbed truck capable of crossing obstacles, comprising a flatbed frame, the lower surface of which is provided with a retractable wheel mechanism for crossing obstacles, the retractable wheel mechanism comprising an external retractable wheel mechanism, a control mechanism, and an internal retractable wheel mechanism, the external retractable wheel mechanism being provided at the front and rear ends of the lower surface of the flatbed frame, the internal retractable wheel mechanism being provided at the middle portion of the lower surface of the flatbed frame, the control mechanism being provided between the external retractable wheel mechanism and the internal retractable wheel mechanism, and the control mechanism being provided with a drive mechanism for driving the retractable wheels of the external retractable wheel mechanism and the internal retractable wheel mechanism, respectively. Its characteristic is that the external retractable wheel mechanism and the internal retractable wheel mechanism are controlled by the drive mechanism to retract and extend the wheels in sequence, thereby achieving the purpose of enabling the hand-pushed flatbed truck to smoothly cross obstacles; its disadvantage is that the structure is relatively complex, making it inconvenient to modify an existing platform-type transfer vehicle.

[0008] The supporting transverse movement device also includes a transverse fixing sleeve and a telescopic rod. The transverse fixing sleeve is fixedly installed on the platform transfer vehicle, and the telescopic rod is slidably installed in the transverse fixing sleeve.

[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0035] Example 1:

[0036] See Figure 1-4 7. A platform transfer device for load equipment includes a platform transfer vehicle 10. Obstacle-crossing assemblies are installed on the left and right sides of the platform transfer vehicle 10. The obstacle-crossing assembly includes two opposing supporting and transverse movement devices 20. The supporting and transverse movement devices 20 include a first push rod device 23 and a second push rod device 25. The first push rod device 23 is installed and connected to the platform transfer vehicle 10. The second push rod device 25 is installed at the telescopic end of the first push rod device 23, and the telescopic end of the second push rod device 25 extends downward. The two second push rod devices 25 of the obstacle-crossing assembly on each side are respectively located on the front and rear sides of the platform transfer vehicle 10. By installing the obstacle-crossing assemblies on the left and right sides of the platform transfer vehicle, and by controlling the coordinated operation of the first push rod device 23 and the second push rod device 25, the wheels of the platform transfer vehicle 10 can be moved over obstacles, facilitating the passage of the platform transfer vehicle.

[0037] In this embodiment, see Figure 1-4 The first push rod device 23 is fixedly installed horizontally on the left and right sides of the platform transfer vehicle 10, and the second push rod device 25 is fixedly installed at the telescopic end of the first push rod device 23. In this way, the first push rod device 23 drives the second push rod device 25 to telescopically move, and the second push rod device 25 can lift the platform transfer vehicle 10.

[0038] In this embodiment, the first push rod device 23 and the second push rod device 25 are hydraulic cylinders or electric cylinders.

[0039] The platform transfer vehicle 10 is further equipped with a control system 30 , which is used to control the coordinated operation of the first push rod device 23 and the second push rod device 25 .

[0040] When the first push rod device 23 and the second push rod device 25 are hydraulic cylinders, the control system 30 is a hydraulic control system. The hydraulic control system uses the power of the platform transfer vehicle 10. The hydraulic control system includes a hydraulic station and a hydraulic control system. The hydraulic station provides pressure medium to the hydraulic cylinders via a hydraulic oil pump. The hydraulic control system controls the coordinated operation of the hydraulic cylinders via hydraulic control valves. The hydraulic control system is a conventional technical means of hydraulic and control technology and will not be described in detail here.

[0041] When the first push rod device 23 and the second push rod device 25 are electric cylinders, the start and stop of each electric cylinder are controlled by the PLC or buttons of the control system 30, so that the first push rod device 23 and the second push rod device 25 are controlled to operate in a coordinated manner.

[0042] Example 2:

[0043] In this embodiment, see Figure 2 、 4 The supporting transverse movement device 20 also includes a transverse fixing sleeve 21 and a telescopic rod 22. The transverse fixing sleeve 21 is fixedly mounted on the platform transfer vehicle 10, and the telescopic rod 22 is slidably mounted within the transverse fixing sleeve 21. The fixed end of the first push rod device 23 is bolted to the fixed seat 11 on the platform transfer vehicle 10 for support. The earrings at the telescopic end of the first push rod device 23 are connected to the double ear seats at one end of the telescopic rod 22 via a pin. The other end of the telescopic rod 22 is mounted with a second push rod device 25. Through the above structure, when the platform transfer vehicle 10 is jacked up, the load is borne by the transverse fixing sleeve 21 and the telescopic rod 22, thereby improving the stability of the structure.

[0044] Example 3:

[0045] Based on Example 2, see Figure 5 、 6 The telescopic rod 22 is provided with mounting grooves 221 on the upper and lower sides respectively, and rollers 222 are installed in the mounting grooves 221 through pins 223. The rollers 222 are supported by the inner wall of the horizontal fixing sleeve 21 in a rolling manner. Through the above structure, the flexibility of the telescopic rod 22 when loaded is improved.

[0046] exist Figure 6 、 7 In the embodiment, a plurality of mounting slots 221 are respectively provided on the upper and lower sides of the telescopic rod 22 , and a roller 222 is installed in each mounting slot 221 via a pin 223 .

[0047] Certainly, the mounting groove 221 can also be a continuous groove. In the present embodiment, the roller 222 adopts a bearing. The upper and lower sides of the roller 222 are respectively provided with two rows.

[0048] Example 4:

[0049] On the basis of Example 2 or Example 3, see Figure 4 , the supporting transverse movement device 20 also includes a longitudinal fixing seat 24, and the second push rod device 25 is installed and fixed with the longitudinal fixing seat 24. In this scheme, by arranging the longitudinal fixing seat 24, it is convenient to install, connect and fix the second push rod device 25 with the telescopic rod 22.

[0050] Furthermore, the longitudinal fixing seat 24 is a hollow structure with a closed top. The second push rod device 25 is installed in the hollow structure of the longitudinal fixing seat 24, and the fixed end of the second push rod device 25 is fixed to the top of the longitudinal fixing seat 24. The supporting transverse movement device 20 also includes a longitudinal sliding sleeve 27, which is slidably installed in the longitudinal fixing seat 24. The outer wall of the longitudinal sliding sleeve 27 slides with the inner wall of the longitudinal fixing seat 24, and the telescopic end of the second push rod device 25 is connected to the longitudinal sliding sleeve 27. Through the above structure, the longitudinal sliding sleeve 27 is connected to the longitudinal fixing seat 24 in a sliding and guiding manner, thereby improving the structural stability. When the second push rod device 25 extends, it drives the longitudinal sliding sleeve 27 to extend downward, thereby lifting the platform transfer vehicle 10.

[0051] In one embodiment, the bottom of the longitudinal sleeve 27 is sealed to increase the force-bearing area, and the telescopic end of the second push rod device 25 is connected and fixed to the bottom of the longitudinal sleeve 27. In this embodiment, the telescopic end of the second push rod device 25 can be screwed to the threaded sleeve at the bottom inner side of the longitudinal sleeve 27 via an external thread, or the telescopic end of the second push rod device 25 can be provided with a pin hole, and the pin shaft passes through the side wall of the longitudinal sleeve 27 and the pin hole, thereby connecting the telescopic end of the second push rod device 25 to the longitudinal sleeve 27.

[0052] In another embodiment, see Figure 4 The bottom of the longitudinal sleeve 27 is fixedly connected to the support plate 26, which further increases the force-bearing area. The telescopic end of the second push rod device 25 is connected and fixed to the support plate 26. In this solution, the telescopic end of the second push rod device 25 can be screwed to the threaded sleeve on the upper side of the support plate 26 through an external thread, or the telescopic end of the second push rod device 25 is provided with a pin hole, and the pin shaft passes through the side wall and the pin hole of the longitudinal sleeve 27, thereby connecting the telescopic end of the second push rod device 25 to the longitudinal sleeve 27.

[0053] The working principle or action process of the utility model is as follows:

[0054] See also Figure 1 、 4 7. When the platform transfer vehicle 10 encounters an obstacle 40, the front wheels of the platform transfer vehicle 10 are moved close to the obstacle 40. Afterwards, the two first push rod devices 23 of the obstacle crossing assembly located at the front end of the platform transfer vehicle 10 are extended.

[0055] Afterwards, the four second push rod devices 25 of the obstacle crossing components on both sides extend synchronously to lift the platform transfer vehicle 10. Figure 7 .

[0056] Afterwards, the two first push rod devices 23 of the obstacle crossing components on both sides located at the front end of the platform transfer vehicle 10 retract, and the two first push rod devices 23 located at the rear end of the platform transfer vehicle 10 extend, thereby moving the platform transfer vehicle 10 forward. When the front wheels pass the obstacle 40, the four second push rod devices 25 retract synchronously, and then the two first push rod devices 23 at the front end extend, and the two first push rod devices 23 at the rear end retract.

[0057] The platform transfer vehicle 10 moves forward a certain distance so that the rear wheels are close to the obstacle 40. The same method as above is used to make the rear wheels go over the obstacle 40. After the obstacle is overcome, the obstacle-overcoming components are reset and fully retracted.
