The present invention relates to a handling device and a carrying device. [Prior Art] U.S. Patent No. 4,432,426 discloses a crawler type handling device, which is mainly used for carrying a wheelchair user up and down stairs. The crawler type carrying device is provided with a set of two crawler belts for facilitating pushing, pulling or changing directions to the left and right sides. The rear transport wheel (transp (10) whell), when the user pushes the transport wheel to project the material, it can read, pull or change the traveling direction of the crawler transport device to the left and right sides in a labor-saving manner. Disadvantages: 1. The transport wheels only provide the rear structural support of the crawler handling device, so that in use, the user must apply and maintain a downward pressure on the operating lever to front of the crawler handling device. The structure is lifted off the ground so that it can be moved by the transport wheels. However, the force to apply and maintain the press is quite laborious, especially when a wheelchair patient is mounted, the load will be increased more and the use is less difficult. 2. The 5 荨 transport wheel does not use a free wheel that can rotate 360 degrees horizontally 'can only rotate parallel to the track'. Therefore, when the track type handling device is changed to the left and right sides, the user still needs to The front structure of the crawler type conveying device is lifted off the ground, and then the user uses the transport wheels as a fulcrum to apply force to the left and right sides to achieve the purpose of changing direction, and the use is still laborious and inconvenient. The transport wheels are manually pulled. When the load of the crawler handling device increases, the pulling process is more difficult and laborious, thereby affecting the ease of use of the crawler handling device. [New content] Therefore, an object of the present invention is to provide a crawler type conveying device that greatly enhances the use of convenience. Thus, the novel crawler handling device comprises a carrying platform, a driving unit, and a steering unit. The driving unit is coupled to the carrying platform, and comprises two horses (4) running along a front-rear direction and running along the left-right direction, and the track-steering unit is coupled to the roller of the carrying platform a driving element that moves along the front and rear direction of the front and rear direction, and the moving rod moves along the front and rear directions, and is dispersed in the carrying platform, the connecting rod has - one end portion thereof and - opposite to the first end portion The remaining two nets are synchronized by the link of the link in the 1: position, the lower use position, and the position of the fitter's receiving position. A warfare ten-inch device: the new ^ beneficial effect is: when the user wants to carry the track-type transport or change the direction to the left and right sides, as long as the design through, use the current brewing _ turn white single 7 ζ material rod and (4) The roller can make the roller/moving roller disperse below the bottom of the carrying platform. At this time, due to the support, the front and rear structures of the crawler M404810 are automatically pulled away from the ground, so that the material can be easily Push or pull the crawler handling device or change direction to the left and right sides. [Embodiment] The foregoing and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. As shown in Figure 1, 2 '3, the new crawler type handling device

The ears 24 are adjacent the front ends of the tracks 31 which are adjacent the rear ends of the tracks 31. The steering unit 40 is coupled to the carrying platform 2〇, and includes three rollers 41 pivotally connected to the carrying platform 2〇 in the left and right direction, a connecting rod 42 extending along the front and rear directions, and a linkage of the connecting rod a driving member 43 that moves again in the front-rear direction, a front boring shaft 44 passing through the front pivoting lug 24, a circumscribing yaw axis 44, and a pair 46, and two are respectively connected thereto. The rear pivot is placed on the roller seat 45 of the front towing shaft 44, and the crank 47 at both ends of the front link shaft 27 of the rear link base 29. The rollers 41 are dispersed in the rollers 41. The ones are arranged in the ϋ/千口2〇' in the present embodiment, and the two sides are disposed at opposite positions of the rear side, and the rear two rollers 41 The 3° slanted rollers 41 respectively located on the carrying platform (7) are respectively coupled to the roller brackets 45 盥 the crank shanks 47. In actual manufacture, the roller cymbals can also be arranged in three or more quantities, for example, two Scroll wheel 4].^ Configure the position. The two side rollers 41 have a first end portion 421 of the / agricultural wheel 41 and a second portion 421 opposite to the end portion 421 and interlocking the remaining two rollers 第. In the present embodiment, the portion 421 is inserted into the front link base 46, and the second end portion 422 is coupled to the rear link base 29. The drive member 43 is pivotally connected to the middle ear portion and Between the rear lugs, the driving element 43 employs an electric cylinder in the present embodiment, and the actual manufacturing % may also employ a motor 'the operation of the motor 32 and the operation of the driving element' is controlled by the operation interface 22 . As shown in FIGS. 1, 4, 5, and 6, the rollers 41 are synchronously subjected to the linkage of the links 42 to the position of use below the crawler belts 31 (as shown in FIGS. 5 and 6). Switching between the storage positions (shown in FIGS. 1 and 4) incorporated in the carrying platform 2〇, the steering unit 4〇 receives the roller 41 that is linked to the first end, and is capable of The horizontal wheel rotates 360 degrees freely, and the rest is rolled by the second end 422. M404810 Second:: Use these fixed wheels to visit the same track as the track 31. If there are two The roller 41 is located at the front, and the second fading portion: the second portion 41 is connected to the two rollers 41 at the same time, and the two "-1"s at the front are all freewheels that can rotate horizontally by 36 degrees. The type moves ^j, 4, 5, 7 In the following, the following description will be given for the use of the crawler belt. When the user wants to push, pull or change the direction to the left and right sides, the control of the operation interface 22 and the steering unit are as follows. 4〇 design, using the drive component "connected to the 42 and the synchronous linkage of the rollers 41, In order to allow the roller W to be selected below the crawler belt 31, at this time, since the roller is dispersed, the branch is formed under the load-bearing platform 2G, and the square and rear structures of the crawler belt 31 are automatically separated from the ground. The crawler type handling device 200 can easily push, pull or change the direction to the left and right sides, and does not require laborious manual operation, thereby achieving the purpose of greatly improving the convenience of use. However, the above-mentioned one is the preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent change and modification according to the novel application and the scope of the specification. , are still within the scope of this new patent.
