Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, are not to be construed as limiting the present invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The first embodiment is as follows:

referring to fig. 1 and 2, the weight pallet of the present embodiment includes a small pallet 2 and a transition plate 1. The transition plate 1 is fixed above the small tray 2. First limiting blocks 21 are symmetrically arranged at one end of the small tray 2 and far away from the central point, and second limiting blocks 22 are arranged at the other end of the small tray 2 and near to the central point. Two sides of one end of the transition plate 1 are respectively provided with an open type limiting groove 11 for limiting the position through a first limiting block 21; the other end of the transition plate 1 is provided with a closed limiting groove 12 for embedding a second limiting block 22 therein to ensure that the transition plate 1 is fixed on the small tray 2. The first limiting block 21 and the second limiting block 22 can be fixedly connected to the small tray 2 by welding. The upper surface of crossing cab apron 1 is provided with a plurality of fixed blocks 13 for the fixed balancing weight of placing on little tray 2 avoids when the later stage operation, and the balancing weight breaks away from little tray 2, protection operation personnel's health safety. The transition plate 1 arranged in this way can be placed in a row of configuration blocks, and compared with the small tray 2 in the prior art, the space occupation can be saved.

Preferably, the first limiting block 21 is a semicircular block, and the open limiting groove 11 is also designed to be semicircular correspondingly to limit the position.

Preferably, the second limiting block 22 can be designed as two symmetrically arranged semicircular blocks, and the closed limiting groove 12 can be correspondingly designed as an arc shape to fix and limit the positions of the two semicircular blocks.

Preferably, as shown in fig. 4 and 5, an external base 23 may be further connected to both sides of the small tray 2, and the external base 23 and the small tray 2 are connected by a pin. The small tray 2 after the connection increases the area for placing the balancing weights, and two rows of balancing weights can be placed under the action of the external base 23 according to actual working conditions or the requirement of the balancing weights. The external base 23 includes an upper seat 231 and a lower seat 232. The upper holder 231 and the lower holder 232 are fixed by two connecting plates 233. The connecting plate 233 is fixedly connected with the small pallet 2 through a pin. Stoppers 234 are provided at both ends of the working surface of the upper holder 231 to fix the two-column arrangement and prevent the occurrence of displacement.

Example two:

referring to fig. 3, the utility model provides a crawler crane, including promoting support 3, arm-tie 5, big tray 4 and embodiment one in the counter weight tray, little tray 2 in this counter weight tray is through the round pin hub connection between two promotion supports 3. The bottom ends of the two lifting brackets 3 are respectively connected with the tray through a pulling plate 5. The crawler crane of the embodiment can install or remove the large tray 4 according to the actual working condition or the counterweight requirement; or the number of rows of weights of the small pallet 2. Since the present embodiment includes the counterweight tray described in the first embodiment, at least the technical effects described in the first embodiment can be produced, and details are not repeated herein.
