The first clamping block and the second clamping block are respectively provided with semicircular grooves. When the first clamping block and the second clamping block are butted, the two semicircular grooves form a through hole for the heat collecting pipe to pass through. One end of the first connecting piece is hinged to the hollow shaft, and the other end is fixedly connected to the first clamping block. One end of the second connecting piece is hinged to the hollow shaft, and the other end is fixedly connected to the second clamping block.

[0011] In the above technical solution, the hoisting rope is a steel wire rope, and the lower end of the steel wire rope is connected with the hollow shaft at the top of the chuck.

[0012] In the above technical solution, the upper fastener includes an upper screw and an upper nut; a first upper threaded hole is provided on the upper part of the first clamping block, and a second upper threaded hole is provided on the second clamping block at a position corresponding to the first upper threaded hole. The upper screw is inserted into the first upper threaded hole and the second upper threaded hole, and a nut is installed on the end of the upper screw to clamp and fix the upper parts of the first clamping block and the second clamping block.

[0014] The advantages and beneficial effects of the present invention are:

[0015] (1) The present invention clamps the heat collecting tube by the first clamping block and the second clamping block, which can make the hoisting process safer and prevent the heat collecting tube from being damaged due to the shaking of the hoisting rope when the hoisting rope is directly hoisting the heat collecting tube.

[0016] (2) The hoisting bracket of the present invention is a triangular structure, and a plurality of support rods are arranged inside, so that a plurality of triangular structures are formed inside the hoisting bracket, so that the hoisting bracket is subjected to uniform and stable force during hoisting.

[0030] For ease of explanation, spatial relative terms such as "upper", "lower", "left", and "right" are used in the embodiments to illustrate the relationship between one element or feature shown in the figures and another element or feature. It should be understood that, in addition to the orientation shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0031] Moreover, relational terms such as “first” and “second” are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any actual relationship or order between these components.

[0032] The above is an exemplary description of the present invention. It should be noted that, without departing from the core of the present invention, any simple deformation, modification or other equivalent replacement that can be made by other skilled in the art without expending creative labor falls within the scope of protection of the present invention.
