Detailed Description

In order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the present utility model easy to understand, the following further describes how the present utility model is implemented with reference to the accompanying drawings and the detailed description.

Referring to fig. 2 and 3, the novel T-type lifting mechanism for a dump truck provided by the utility model comprises two mounting arms 1, two triangular arms 6, two pulling plates 3, a lifting cylinder 4, two cylinder pins 2 and a triangular arm pin 5, wherein one end of each triangular arm 6 is hinged together through one mounting arm 1, the other end of each triangular arm 6 is hinged with one end of each pulling plate 3 through one triangular arm pin 5, the other end of each pulling plate 3 is hinged together through the other mounting arm 1, the lifting cylinder 4 is arranged between the two pulling plates 3, one end of each lifting cylinder is hinged with the two pulling plates 3 through one cylinder pin 2, and the other end of each lifting cylinder is hinged with the two triangular arms 6 through the other cylinder pin 2. When in use, the upper parts of the two triangular arms 6 are hinged with a carriage 8 of the dump truck through the mounting arm 1; the lower parts of the two pulling plates 3 are hinged with a subframe 9 of the dump truck through the mounting arms 1.

Specifically, as a specific embodiment of the present utility model: referring to fig. 3, the T-type lifting mechanism further includes a connecting plate 7, and the connecting plate 7 is fixedly disposed at a corner of the two triangular arms 6 near one ends of the two pull plates 3.

Specifically, as a specific embodiment of the present utility model: referring to fig. 4, each mounting arm 1 includes a fixing block 101 and two rotating shafts 102, and the two rotating shafts 102 are fixedly disposed at two ends of the fixing block 101, and are used for hinging with two triangle arms 6 or two pulling plates 3. More specifically, as shown in fig. 2 and 3, the mounting arm 1 hinged corresponding to the two triangular arms 6, and the two rotating shafts 102 provided on the mounting arm are respectively and correspondingly rotatably inserted into the two triangular arms 6; the two rotating shafts 102 arranged on the mounting arms 1 correspondingly hinged with the two pulling plates 3 are respectively correspondingly and rotatably penetrated in the two pulling plates 3.

Specifically, as a specific embodiment of the present utility model: referring to fig. 4, a circular hole 103 is further formed in the middle of the fixing block 101, and the circular hole 103 is used for penetrating the pin shaft 10 connected with the carriage 8 or the subframe 9. More specifically, as shown in fig. 6, 8 and 9, the mounting arm 1 hinged in correspondence with the two triangular arms 6 is provided with a circular hole 103 for passing through the pin 10 connecting the carriage 8; the mounting arms 1 are correspondingly hinged with the two pull plates 3, and round holes 103 are arranged on the mounting arms and are used for penetrating pin shafts 10 connected with the auxiliary frame 9.
