Description

Technical Field

[0001] This utility model belongs to the field of transfer cart technology, specifically an extendable and connectable in-field transfer device. Background Technology

[0002] On-site transfer devices, also known as transfer trolleys, are specialized equipment used for the horizontal transport of materials, equipment, or components within a construction site. The trolley body is generally made of sturdy metal materials and is moved by swivel wheels, making it a short-distance transport tool.

[0003] Utility model patent application publication number 201620630763.9 discloses an assembled handcart, including a loading plate, a bracket, and rollers. The rollers are installed around the bottom surface of the loading plate. The front wall of the loading plate has a mounting groove, and the bottom of the bracket is fitted into the mounting groove. A connecting plate is installed at the rear end of the loading plate. Rollers are installed around the bottom surface of the connecting plate. Both the rear wall of the loading plate and the rear wall of the connecting plate have connecting grooves. The front wall of the connecting plate has a connecting block that matches the connecting groove. The connecting groove has a first screw hole that penetrates the top surface of the loading plate. The connecting block has a second screw hole on the same vertical line as the first screw hole. Bolts are screwed into the first and second screw holes. Multiple connecting plates can be installed as needed to increase the length of the loading plate, which can better transport objects, improve work efficiency, and facilitate easy replacement of damaged connecting plates.

[0004] As can be seen from the above patent, there is an extendable and splicable in-field transfer device. However, it still has shortcomings in actual use. The most obvious one is that the current transfer device is mainly fixed by bolts during the splicing process. Operators need to use screwdrivers and other disassembly tools to disassemble and install it, which is not conducive to the rapid splicing of the transfer device. It is very inconvenient in actual use and reduces the efficiency of the transfer device. Therefore, we propose an extendable and splicable in-field transfer device. Utility Model Content

[0005] The purpose of this invention is to provide an extendable and connectable in-field transfer device to solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] Specifically, this application describes an extendable and connectable in-field transfer device, comprising: a movable platform and a movable plate slidably disposed at the bottom of the movable platform; trapezoidal blocks and mounting plates are fixedly connected to both sides of the movable platform; the side wall of the mounting plate is provided with trapezoidal grooves that match the trapezoidal blocks; a first sliding rod and a second sliding rod are fixedly connected to the bottom of the movable platform; the second sliding rod is located at one end of the first sliding rod; the movable plate is slidably connected to the outer side wall of the first sliding rod; and an elastic element that applies an upward pushing force to the movable plate is provided on the first sliding rod.

[0008] A limiting plate is fixedly connected to one side wall of the movable plate. The bottom of the trapezoidal block and the bottom of the mounting plate are both provided with limiting grooves that match the limiting plate. An adjusting component is provided on the movable plate to facilitate driving the movable plate to move downward.

[0009] As a preferred technical solution of this application, the elastic element includes a spring, and a first positioning plate is fixedly connected to the bottom of the first slide rod, and the spring is fixedly connected between the top of the first positioning plate and the bottom of the movable plate.

[0010] As a preferred technical solution of this application, the adjusting member includes a movable plate, which is fixedly connected to one side of the movable plate and slidably connected to the outer wall of the second slide rod.

[0011] As a preferred technical solution of this application, a second positioning plate is fixedly connected to the bottom of the second slide rod.

[0012] As a preferred technical solution of this application, the top of the movable plate is fixedly connected to a mounting base, the inner cavity of the mounting base is rotatably connected to a rotating rod, the bottom of the rotating rod penetrates the top of the movable plate and is fixedly connected to a pressure plate, the pressure plate is used in conjunction with a second positioning plate, and the top of the rotating rod is fixedly connected to a rotating plate.

[0013] As a preferred technical solution of this application, a protective cylinder is fixedly connected to the bottom of the movable plate, and the first positioning plate is slidably disposed on the inner side wall of the protective cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the scheme of this application:

[0016] 1. By setting trapezoidal blocks and mounting plates on both sides of the mobile platform, and opening trapezoidal grooves on the mounting plates, the two sets of mobile platforms can be spliced ​​by moving the trapezoidal blocks into the trapezoidal grooves. An elastic element applies an upward force to the movable plate, which drives the limiting plate to move into the limiting grooves on the trapezoidal blocks and the mounting plate, thus limiting the trapezoidal blocks and the mounting plate. During assembly, simply press the adjusting element, which drives the movable plate to move downward. The movable plate then drives the limiting plate out of the limiting groove, thus separating the trapezoidal blocks and the mounting plate. This facilitates the rapid splicing of the transfer device and improves the efficiency of the transfer device.

[0017] 2. By setting a movable plate, which supports a rotating rod via a mounting base, and a pressure plate is installed via the rotating rod, during assembly, the rotating rod is first rotated, causing the pressure plate to rotate. Then, the rotating rod is pressed down, causing the pressure plate to move below the second positioning plate. Next, the rotating rod is rotated again, and at this time, the pressure plate is moved upward by the elastic element. At this point, the pressure plate contacts the second positioning plate, preventing it from moving upward further. This achieves positioning after the limit plate moves downward, facilitating the assembly of the transfer device and making it convenient to use. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-3 An extendable, modular in-field transfer device includes: a movable platform 100 and a movable plate 200 slidably disposed at the bottom of the movable platform 100. The movable plate 200 supports a limiting plate 210. Trapezoidal blocks 110 and mounting plates 150 are fixedly connected to both sides of the movable platform 100, respectively. The side wall of the mounting plate 150 has a trapezoidal groove 151 that matches the trapezoidal block 110. The trapezoidal block 110 slides within the trapezoidal groove 151 to connect with the mounting plate 150. A first sliding rod 120 and a second sliding rod 140 are fixedly connected to the bottom of the movable platform 100. The second sliding rod 140 is located at the bottom of the first sliding rod 120. At one end of the slide rod 120, the first slide rod 120 is used to support the movable plate 200. The movable plate 200 is slidably connected to the outer side wall of the first slide rod 120. An elastic element is provided on the first slide rod 120 to apply an upward pushing force to the movable plate 200. A limiting plate 210 is fixedly connected to one side wall of the movable plate 200. The limiting plate 210 enters the limiting groove to limit the trapezoidal block 110 and the mounting plate 150. The bottom of the trapezoidal block 110 and the bottom of the mounting plate 150 are both provided with limiting grooves that match the limiting plate 210. An adjusting element is provided on the movable plate 200 to facilitate driving the movable plate 200 to move downward.

[0027] Please see Figure 3 The elastic element includes a spring 131. The bottom of the first slide rod 120 is fixedly connected to a first positioning plate 130. The spring 131 is fixedly connected between the top of the first positioning plate 130 and the bottom of the movable plate 200. The spring 131, in conjunction with the first positioning plate 130, applies an upward elastic force to the movable plate 200.

[0028] Please see Figure 2 and Figure 3The adjusting component includes a movable plate 220, which is fixedly connected to one side of the movable plate 200. The movable plate 220 is slidably connected to the outer wall of the second slide rod 140, and the movable plate 200 is moved downward by the movable plate 220.

[0029] Please see Figure 2 and Figure 3 The bottom of the second slide bar 140 is fixedly connected to the second positioning plate 141, which limits the pressure plate 241.

[0030] Please see Figure 2 and Figure 3 A mounting base 230 is fixedly connected to the top of the movable plate 220. A rotating rod 240 is rotatably connected to the inner cavity of the mounting base 230. The bottom of the rotating rod 240 passes through the top of the movable plate 220 and is fixedly connected to a pressure plate 241. The pressure plate 241 works in conjunction with the second positioning plate 141. A rotating plate 242 is fixedly connected to the top of the rotating rod 240. The rotating rod 240 drives the movable plate 220 to move downward and drives the pressure plate 241 to rotate. When the pressure plate 241 rotates to a position close to the second positioning plate 141, the upward movement of the pressure plate 241 will be blocked by the second positioning plate 141, and the movable plate 200 and the limiting plate 210 will be positioned. At this time, the trapezoidal block 110 and the mounting plate 150 can be connected by pushing the movable plate 100.

[0031] Please see Figure 2 and Figure 3 The bottom of the movable plate 200 is fixedly connected to a protective cylinder 250. The first positioning plate 130 is slidably disposed on the inner side wall of the protective cylinder 250, and the spring 131 is isolated and protected by the protective cylinder 250.

[0032] Specifically, in use, the device first rotates the rotating rod 240 and the pressure plate 241 via the rotating plate 242, causing the pressure plate 241 to rotate to the side away from the second positioning plate 141. Then, the rotating rod 240 is pressed down, causing the rotating rod 240 to move the moving plate 220 and the pressure plate 241 downwards. At this time, the movable plate 200 moves the limiting plate 210 out of the limiting groove on the mounting plate 150. Then, the rotating rod 240 is rotated again, causing the rotating rod 240 to rotate the pressure plate 241 to the side closer to the second positioning plate 141. Then, the rotating rod 240 is released, and the movable plate 220 is pushed by the spring 131. 00 moves upward, and the movable plate 200 drives the movable plate 220 and the pressure plate 241 to move upward. At this time, the pressure plate 241 contacts the second positioning plate 141, preventing the movable plate 220 from moving upward. Then, the trapezoidal block 110 on another set of movable plates 100 is moved into the trapezoidal groove 151. The rotating rod 240 is rotated again. At this time, the spring 131 can drive the movable plate 200 and the limiting plate 210 to move, and the limiting plate 210 is moved into the limiting groove on the trapezoidal block 110 and the mounting plate 150, so that the mounting plate 150 is connected to the trapezoidal block 110, thus completing the splicing of the transfer device.
