Background

The concrete pump truck is an engineering machine which utilizes pressure to convey pre-stirred concrete to a certain height and distance along a distribution pipeline, and is widely applied to modern building engineering. The auxiliary frame is connected with the pump truck for loading and the lower chassis for bearing and connecting. The transfer case is one of core parts of a concrete pump truck taking power by breaking a shaft as a power conversion device. The pump truck can regularly generate transient and strong impact when working, and the transfer case is used as a power conversion device between the chassis and the upper loader, so that the stable work of the transfer case is particularly important. With the increasing number of chassis manufacturers entering the concrete industry, the types of chassis and the types of pump trucks in the industry are gradually diversified. More customers are willing to buy pump trucks with chassis with high acceptance, and the same top-loading equipment is required to be dropped on different chassis. While the traditional transfer case fixing mode needs to use a traveling crane (a bridge crane) to carry out four-step operation when the chassis is replaced: 1. the upper loader is hung down from the original chassis; 2. hanging the transfer case from the original chassis; 3. hoisting the transfer case to a new chassis; 4. and hoisting the upper assembly to the new chassis. The steps are relatively complicated, and the efficiency is low. How to improve the working efficiency when the chassis is frequently replaced while satisfying the stable work of the transfer case becomes a practical problem mainly overcome by the patent.

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", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not 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.

As shown in fig. 1-2, a transfer case mounting and fixing structure is disclosed, which comprises: the top parts of the two sides of the transfer case component 2 are provided with auxiliary connecting bent plates 1, and the bottom parts of the two sides are provided with transfer case brackets 3; the four-connection pump 9 is connected with the transfer case component 2, and the bottom of the four-connection pump 9 is provided with a pump bracket 4; the auxiliary frame 11 is arranged on the chassis, and the transfer case bracket 3 and the pump bracket 4 are connected with the auxiliary frame 11; it should be noted here that the transfer case carrier 3 is connected to the transfer case assembly 2 by a mount 7 and a shock pad 7; the front and the back are connected with the transmission shaft, and the transmission shaft and the chassis can be regarded as a whole, so that the vibration of the transfer case component 2 caused by the pump truck during working can be effectively reduced, and the work of the transfer case component is more stable.

The specific installation mode is as follows: the transfer case bracket 3 and the pump bracket 4 are installed at the appointed position of the chassis girder, the integrated transfer case component 2 and the four-link pump 9 are integrally fallen on the transfer case bracket 3 and the pump bracket 4, and the upper part of the transfer case component 2 is connected with the auxiliary frame 11 through the auxiliary connecting bent plate 1 and the bolts after the auxiliary frame 11 falls on the chassis.

In the embodiment, a rubber pad 5 is arranged at the joint of the pump bracket 4 and the four-link pump 9; the vibration between the pump bracket 4 and the four-connected pump 9 is reduced and kept stable;

as shown in fig. 2, a transfer case mounting plate 10 for fixing an auxiliary connecting bent plate 1 is arranged on the side part of the transfer case component 2, the upper part of the auxiliary connecting bent plate 1 is in a bent plate shape and is connected with an auxiliary frame 11 through a bolt, and the lower part of the auxiliary connecting bent plate is connected with the upper part of the transfer case mounting plate 10 through a bolt; the fixing plate 8 is connected with the transfer case bracket 3 through a fixing piece 7 and a shock pad 7.

Aiming at the current situation that the chassis is frequently replaced (namely different chassis are assembled on the same transfer case), as the auxiliary connecting bent plate 1 (shown in figure 2) is additionally arranged between the upper part of the transfer case component 2 and the auxiliary frame 11, the chassis can be replaced by only hoisting once; when the performance test is carried out on the upper assembly, the upper assembly is fixed by a tool and the power of the transfer case is directly input; when the outlet is installed, the transfer case and the upper installation room are integrated as an auxiliary connecting bent plate 1. Therefore, the upper assembly debugged in the factory does not need to be disassembled and transported, secondary assembly and debugging after the target is reached are avoided, and unnecessary fault points are reduced.
