It should be noted that, in the absence of conflict, the embodiments in this disclosure and the feature vectors in the embodiments can be arbitrarily combined with each other.

[0034] In the related art, pultruded profiles are usually used to make photovoltaic module frames. When the pultruded profile is just formed, it is a continuous profile and needs to be cut into sections before it can be put into use. The traction device in the related art has insufficient traction force, which leads to uncertainty in the traction distance of the pultruded profile and the inability to guarantee the size of the pultruded profile after cutting, affecting subsequent use. The reason for the related problems is that the contact area of ​​the existing traction device with the pultruded profile is limited, which makes the pultruded profile easy to move when traction is performed, thereby failing to guarantee the size of the pultruded profile after cutting, thereby reducing production efficiency.

[0035] In order to solve the problems existing in the related art, the embodiment of the present disclosure provides a crawler-type traction device for traction of pultruded profiles, the crawler-type traction device includes a first traction part, a second traction part and a lifting assembly, the first traction part includes a first bracket, the second traction part is arranged above the first traction part, the pultruded profile is located between the first traction part and the second traction part, the lifting assembly includes a support column, the support column is connected to the second traction part, wherein the first bracket is provided with a guide through hole, the guide through hole penetrates the first bracket along the thickness direction of the first bracket, and the support column extends along the arrangement direction of the first traction part and the second traction part and passes through the guide through hole. In the present disclosure, the support column of the lifting assembly penetrates the guide through hole in the first traction part and then connects to the second traction part to provide support for the second traction part, so that the second traction part is located above the first traction part, and since the extension direction of the support column is perpendicular to the traction direction of the traction device, the relative displacement of the first traction part and the second traction part in the traction direction can be avoided, so as to ensure that the first traction part and the second traction part have the same traction effect on the bottom and top surfaces of the pultruded profile, and improve the stability when traction of the pultruded profile.

[0036] In order to make the purpose, technical solution and beneficial effects of the embodiment of the present disclosure more clear, a crawler traction device provided by the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

[0038] In the present disclosure, the support column of the lifting assembly passes through the guide through hole in the first traction part and is connected to the second traction part to provide support for the second traction part, so that the second traction part is located above the first traction part. Since the extension direction of the support column is perpendicular to the traction direction of the traction device, the relative displacement of the first traction part and the second traction part in the traction direction can be avoided, thereby ensuring that the first traction part and the second traction part have the same traction effect on the bottom and top surfaces of the pultruded profile, thereby improving the stability when traction of the pultruded profile.

[0039] In some embodiments, Figure 3 and Figure 4 As shown, the lifting assembly 3 also includes a plurality of telescopic drive units 32 and a synchronous base 33.

[0045] In some embodiments, Figures 3 to 5 As shown, a driving motor 14 is disposed on both the first traction part 1 and the second traction part 2. The driving motor 14 is located along one side of the first bracket 11. The driving motor 14 extends along the thickness direction of the first bracket 11 (eg, Figure 3 The drive motor 14 includes a first drive motor 141 and a second drive motor 142.
