Description

Technical Field

[0001] The utility model relates to the technical field of assembly process equipment for solar photovoltaic rollers, in particular to a hot assembly detection tool for an assembled solar photovoltaic roller. Background Art

[0002] like Figure 1 The solar photovoltaic roller 1 shown in is an assembled solar photovoltaic roller, which is composed of a hollow roller in the middle and hollow shaft heads assembled on the inner holes at both ends of the hollow roller. In order to improve the assembly accuracy and meet the sealing requirements after assembly, the hollow shaft head and the hollow roller are connected by interference fit, so they need to be assembled by heat-fitting. The specific heat-fitting method is: first, the outer circle of the end of the hollow roller is heated by a high-frequency heating ring, and when the heat-fitting inner hole of the hollow roller for assembling the hollow shaft head expands to a certain size, the hollow shaft head is installed and positioned on the heat-fitting inner hole of the hollow roller by hoisting.

[0003] However, the above-mentioned heat-fitting assembly method of the solar photovoltaic roller also has the following shortcomings: the heating control of the outer circle of the hollow roller end is carried out according to the inspection of the operator, and the operator judges the expansion of the inner hole of the heat-fitting according to the color of the outer circle of the heated hollow roller end, which often leads to excessive heating. On the one hand, it consumes unnecessary heating energy, and on the other hand, excessive heating will also reduce or even destroy the material properties of the solar photovoltaic roller.

[0004] In view of the above problems, the existing technology also uses an internal diameter micrometer to measure the inner hole of the heat sleeve in real time, and accurately controls the expansion of the heat sleeve inner hole by detecting the inner hole of the heat sleeve while heating. However, due to the high temperature and strong radiation heat of the heating part of the hollow roller, there are certain safety hazards when the operator is close to the high-temperature radiation source for measurement; in addition, the efficiency of measuring with an internal diameter micrometer is also low.

[0005] Therefore, it is necessary to improve the existing hot-installation method of solar photovoltaic rollers in view of the above problems. Utility Model Content

[0006] In order to solve the above problems, the utility model proposes a hot-loading detection tool for assembled solar photovoltaic rollers, aiming to improve the hot-loading efficiency and safety of solar photovoltaic rollers. The specific technical solution is as follows:

[0007] A heat-installation detection tool for an assembled solar photovoltaic roller comprises a laser distance measuring component for detecting the inner hole size of a heat-installation sleeve of an assembled solar photovoltaic roller, the laser distance measuring component comprises a heat-proof radiation shielding sleeve, a portable bidirectional laser distance measuring instrument installed in the heat-proof radiation shielding sleeve, and a handle connected to the heat-proof radiation shielding sleeve, a pair of through holes located in a straight line are radially arranged on the heat-proof radiation shielding sleeve, and laser detection rays at both ends of the portable bidirectional laser distance measuring instrument respectively pass through the pair of through holes on the heat-proof radiation shielding sleeve.

[0008] To facilitate observation during measurement, the digital display window on the portable bidirectional laser rangefinder faces the cantilever end of the handle.

[0009] In the utility model, a seat block is arranged inside the heat radiation protection sleeve, a slot body is arranged on the seat block, and the portable bidirectional laser rangefinder is mounted and fixed on the slot body of the seat block.

[0010] As one of the preferred solutions for fixing the portable bidirectional laser rangefinder, the portable bidirectional laser rangefinder is fixed to the groove body of the seat block by gluing.

[0011] As the second preferred solution for fixing the portable bidirectional laser rangefinder, the portable bidirectional laser rangefinder is fixed to the groove body of the seat block by a tightening screw arranged on the seat block; and a rubber pad is arranged between the tightening screw and the side of the portable bidirectional laser rangefinder.

[0012] Preferably, a boss is provided on the seat block, the groove body is opened on the boss of the seat block, and the tightening screw is provided on one side of the boss.

[0013] Preferably, the handle is fixed to the seat block by a threaded connection.

[0014] Preferably, the handle is fixed to the boss of the seat block by a threaded connection.

[0015] In order to achieve automatic centering during measurement (ie, to locate the laser detection ray on the radial line of the inner hole of the thermal sleeve), a pair of diagonal support positioning columns are provided on the outer circle of the thermal radiation protection sleeve, and an angle is formed between the pair of diagonal support positioning columns.

[0016] Preferably, the pair of diagonal support positioning columns are symmetrically arranged relative to the groove body of the seat block.

[0017] More preferably, the pair of diagonal support positioning columns are symmetrically arranged relative to the laser detection ray of the portable bidirectional laser rangefinder.

[0018] In the utility model, the assembled solar photovoltaic roller comprises a hollow roller and a hollow shaft head assembled and connected with the inner holes at both ends of the hollow roller; the end of the hollow roller is provided with the heat-shrink sleeve inner hole.

[0019] In the utility model, the thermal installation detection tool also includes a support positioning frame for positioning the outer circle of the hollow roller during thermal installation, and the number of the support positioning frame is a pair.

[0020] In the utility model, the hot-loading detection tooling also includes a high-frequency heating ring for heating the outer circle of the end of the hollow roller. The high-frequency heating ring is sleeved around the outer circle of the end of the hollow roller, and the lower end of the high-frequency heating ring is fixed on a support.

[0021] The beneficial effects of the utility model are:

[0022] First, the utility model is a heat-mounting detection tool for assembled solar photovoltaic rollers, which is provided with a laser distance measuring component. By using the bidirectional measurement function of a portable bidirectional laser distance measuring instrument, the inner hole of the heat-mounting sleeve on the hollow roller can be detected in real time more conveniently, and the measurement is convenient and the measurement accuracy is high. In addition, a long handle is provided on the laser distance measuring component, and the operator does not need to be close to the radiation heat source when measuring, thereby enhancing the safety of the measurement.

[0023] Second, the utility model provides an assembled solar photovoltaic roller heat installation inspection tooling, and the provision of a heat radiation protection sleeve on the laser ranging component can protect the portable two-way laser rangefinder from damage caused by heat radiation, while reducing the influence of the heat radiation environment on the measurement accuracy of the portable two-way laser rangefinder, thereby further ensuring the measurement accuracy of the inner hole of the heat sleeve.

[0024] Third, the utility model provides an assembled solar photovoltaic roller heat installation detection tooling, and a pair of symmetrically arranged diagonal support positioning columns are arranged on the laser ranging component. The pair of diagonal support positioning columns can realize the precise centering of the laser detection ray during measurement, and is helpful to reduce the load of the operator holding the laser ranging component. The operation is convenient and the measurement is rapid. The operator only needs to support the pair of diagonal support positioning columns on the inner hole of the heat sleeve, and can quickly find the minimum value of the inner hole size reading by slightly lifting or lowering the cantilever end of the handle. The minimum value of the inner hole size reading is the actual inner hole size of the heat sleeve. BRIEF DESCRIPTION OF THE DRAWINGS
