Description

Technical Field

[0001] The utility model relates to the technical field of transport equipment, in particular to a fixed comb tooth transporter. Background Art

[0002] In the prior art, the overall length of the fixed comb teeth is relatively large. When carrying the fixed comb teeth, it is generally necessary to use a longer bracket for lifting. When the bracket is lifted, the head and tail ends are generally connected together through two long shafts and a coupling to connect the power of the head and tail ends together. During the process, the power needs to be output over a long distance. The middle long shaft and coupling are easily damaged due to long-term stress, and they need to be replaced frequently, with high maintenance costs. At the same time, due to the large length of the bracket, it is difficult to ensure the consistency of the lifting height at both ends. When the workpiece is placed on one side of the bracket, the center of gravity of the bracket is unstable, which can easily cause the bracket to tilt and the workpiece to slide sideways, resulting in safety hazards. Therefore, it is necessary to improve and upgrade the prior art. Utility Model Content
