[0032] Example 1:

[0033] Figure 1 This is a schematic diagram of the structure of the first embodiment of the guide rail frame, refer to Figure 1The guide rail frame of this embodiment includes a fixing platform 10 for fixing and installing the guide rail. The two sides of the fixing platform 10 are respectively connected to support assemblies, which include a support member 20 and a first pressing module 30, wherein:

[0034] One end of the support member 20 is connected to the fixing platform 10, and the other end is connected to the first pressing module 30. The connection method can be fixed or detachable. Specifically, in this embodiment, threaded holes are provided on one side of the fixing platform 10 and the first pressing module 30, and screws with external threads that can be screwed into the threaded holes are provided at both ends of the support member 20. The screws and the threaded holes are screwed together to achieve the connection between the support member 20, the fixing platform 10, and the first pressing module 30. The support member 20 can be configured as a rod-shaped structure to facilitate processing and connection and installation.

[0035] A first inclined surface 31 is provided on the first clamping module 30, and the lower side of the first inclined surface 31 is closer to the fixed platform 10 than the upper side of the first inclined surface 31, so that the guide rail frame can be installed on the mounting structure with the mounting inclined surface through the first inclined surfaces 31 on both sides of the fixed platform 10, and the mounting inclined surface can fit with the first inclined surface 31. Therefore, according to the force principle of the inclined surface, under the action of the gravity of the guide rail frame, the guide rail installed on the guide rail frame, and the material transported by the guide rail, the external mounting structure can have a reaction force on the first clamping module 30 upward and toward the fixed platform 10, so the guide rail frame is installed more stably.

[0036] Therefore, it is only necessary to place the guide rail frame on the mounting structure with the above-mentioned mounting slope, and then the guide rail can be installed on the guide rail frame, so that materials can be transported through the guide rail, which improves work efficiency. Transporting materials through the guide rail can achieve higher transportation accuracy compared with manual operation or machine lifting methods.

[0037] In order to adapt to different installation widths, the distance between the first pressing module 30 and the fixing platform 10 can be set to be adjustable. The adjustment method can be various, and the specific method can be:

[0038] The support member 20 may be configured to be length-adjustable, such as a telescopic rod, and the distance between the first pressing module 30 connected to both ends of the support member 20 and the fixing platform 10 may be adjusted by the length of the support member 20 ;

[0039] Alternatively, the position where the first pressing module 30 is connected to the support member 20 can be adjusted along the length direction of the support member 20. For example, a screw having a certain length is provided at one end of the support member 20 connected to the first pressing module 30, and a threaded hole is provided in the first pressing module 30. The screw is screwed to the threaded hole of the first pressing module 30, and the position where the first pressing module 30 is connected to the screw can be adjusted by rotating the screw, thereby adjusting the distance between the first pressing module 30 and the fixing platform 10.

[0040] Alternatively, the position where the support member 20 is connected to the fixing platform 10 can be adjusted along the length direction of the support member 20. For example, a screw with a certain length is set at one end of the support member 20 connected to the fixing platform 10, and a threaded hole is set on the fixing platform 10. The screw is screwed to the threaded hole of the fixing platform 10. By rotating the screw, the position of the fixing platform 10 and the screw can be adjusted, thereby adjusting the distance between the first clamping module 30 and the fixing platform 10.

[0041] Example 2:

[0042] Figure 2 This is a schematic diagram of the structure of the second embodiment of the guide rail frame, refer to Figure 2 This embodiment differs from the first embodiment described above in that a limiter is provided on the first inclined surface 31 of the first clamping module 30. This limiter limits the horizontal displacement of the first inclined surface 31 relative to the mounting inclined surface, further ensuring stable installation of the guide rail frame. Accordingly, a corresponding limiter structure is required on the external mounting structure to cooperate with the limiter. For example, the limiter may be a boss 32 protruding outward from the first inclined surface 31, or a groove recessed inward from the first inclined surface 31.

[0043] Example 3:

[0044] Figure 3 is a structural diagram of an embodiment of the fixing platform 10, refer to Figure 2 、 3 This embodiment is an improvement on the above embodiment, differing in that: the outer surface of the fixing platform 10 is provided with a plurality of mounting holes 11, and the inner surface is provided with positioning portions 12. Positioning portions 12 are arranged along the upper and lower edges of the fixing platform 10 and are used to abut against the mounting surface of the external mounting structure located inside the fixing platform 10, thereby preventing the fixing platform 10 from flipping or tipping over. Positioning portions 12 can be configured as a triangular structure, connected to the inner surface of the fixing platform 10 via an edge corresponding to one side of the triangular structure. After installation, the triangular structure can abut against the mounting surface through one corner, thereby adapting to irregular mounting surfaces and providing an anti-tilt function.

[0045] Connecting holes 15 are provided on both sides of the fixing platform 10 for connecting the support member 20. The connecting holes 15 can be set as threaded holes. Accordingly, one end of the support member 20 for connecting to the fixing platform 10 is provided with a screw with an external thread. The connection between the fixing platform 10 and the support member 20 is achieved by screwing the screw and the threaded hole.

[0046] Example 4:

[0047] Figure 4 This is a structural diagram of an embodiment of a guide rail fixing device. Figure 5 is a structural diagram of an embodiment of the first pressing module 30 and the second pressing module 40, and Figure 4 、 5 The guide rail fixing device of this embodiment includes a second clamping module 40 and a guide rail frame of any of the above embodiments. A second inclined surface 41 is provided on the second clamping module 40. The upper side of the second inclined surface 41 is farther away from the fixing platform 10 than the lower side of the second inclined surface 41; the first inclined surface 31 and the second inclined surface 41 can fit each other, and the second clamping module 40 can be supported on the first inclined surface 31 of the first clamping module 30 through the second inclined surface 41. Therefore, the guide rail frame can be erected on the second inclined surface 41 of the second clamping module 40. At this time, the second inclined surface 41 can be used as an installation inclined surface of the guide rail frame.

[0048] In an optimized embodiment, a limiting structure is provided between the first inclined surface 31 and the second inclined surface 41, thereby limiting the first and second pressing modules 30 and 40 to prevent them from shifting horizontally, and providing positioning and guidance for the installation of the first and second pressing modules 30 and 40, making installation convenient and accurate. The specific implementation of the limiting structure is as follows:

[0049] The second inclined surface 41 is provided with an inwardly concave groove 42, which extends in the up-down direction; the first inclined surface 31 is provided with an outwardly convex boss 32, which extends in the up-down direction, and the boss 32 can be wedged into the groove 42, and the boss 32 and the groove 42 are combined into a limiting structure between the first inclined surface 31 and the second inclined surface 41. When the first clamping module 30 is installed on the second clamping module 40, the boss 32 and the groove 42 extending in the up-down direction also play a positioning and guiding role in the installation of the first clamping module 30, which helps to install it quickly and accurately; or conversely, the second inclined surface 41 is provided with an outwardly convex boss, which extends in the up-down direction; the first inclined surface 31 is provided with an inwardly concave groove, which extends in the up-down direction, and the boss can be wedged into the groove, and the boss and the groove are combined into a limiting structure between the first inclined surface 31 and the second inclined surface 41, and its function is the same as the former.

[0050] The guide rail fixing device of this embodiment is suitable for external mounting structures having two parallel, opposing mounting surfaces. The two second clamping modules 40 can be first positioned on the two opposing mounting surfaces, maintaining them in a straight line with the second inclined surface 41 facing diagonally upward. The guide rail frame is then mounted on the second clamping modules 40, such that the first inclined surface 31 and the second inclined surface 41 are aligned. Based on the force-bearing principle of inclined surfaces, due to gravity, the first clamping modules 30 at both ends of the guide rail frame will tend to slide downward, exerting an outward force on the second clamping modules 40 to support the mounting surfaces, thereby ensuring a more secure fixation. The alignment of the first inclined surface 31 and the second inclined surface 41 allows the second clamping modules 40 to limit the first clamping modules 30, preventing the first clamping modules 30 from sliding further downward, placing them in a self-locking state and maintaining a stable installation.

[0051] In other optimized embodiments, a rubber pad 43 may be provided on the second clamping module 40 on the other side away from the second inclined surface 41, a threaded hole 33 may be provided on the first clamping module 30, screws may be provided at both ends of the support member 20, and the support member 20 may be screwed to the threaded hole 33 via the screw to achieve a fixed connection between the support member 20 and the first clamping module 30. An annular boss 34 may also be provided around the outer side of the threaded hole 33 to strengthen the connection between the support member 20 and the first clamping module 30. Similarly, a threaded hole may also be provided on the fixing platform 10, and the support member 20 and the fixing platform 10 may be screwed together. After the guide rail fixing device is installed on an external mounting structure having two parallel opposing mounting surfaces in the above manner, the support member 20 may be rotated to make the rubber pads 43 of the second clamping modules 40 on both sides and the two parallel opposing mounting surfaces change from a non-contact state to a contact state, and then to a clamped state, so that the guide rail fixing device remains stable in the set position, thereby fixing the guide rail on the fixing platform 10 to achieve the fixation of the guide rail.

[0052] The guide rail fixing device of the present embodiment is suitable for fixing guide rails on irregular surfaces. It is very difficult to set up guide rails on irregular surfaces. The fixing of the guide rails is difficult and will affect the positioning accuracy. In severe cases, it may even cause engineering accidents. With the guide rail fixing device of the present embodiment, it is only necessary to set up a fixing plate with two parallel and opposite mounting surfaces on the irregular surface, so that the second clamping modules 40 at both ends of the guide rail fixing device can be supported on the fixing plate. The first inclined surface 31 and the second inclined surface 41 provided with the first clamping module 30 and the second clamping module 40 enable the fixing frame to be stably overlapped on the second clamping module 40, and have a component force perpendicular to the surface of the fixing plate on the second clamping module 40, so that the fixation is more secure, so that the guide rail can be fixedly installed on the fixing platform 10 of the guide rail fixing device, and the fixed installation of the guide rail on the irregular surface is realized without being restricted or affected by the irregular surface structure, thereby ensuring the stability of the installation and the accuracy of the guide rail positioning, thereby improving the running accuracy and transportation efficiency of the guide rail.

[0053] Embodiment 5:

[0054] Figure 6 This is a schematic diagram of an embodiment of a guide rail system arranged on a vertical surface. Figure 6 A guide rail system of this embodiment includes a guide rail 50 and a guide rail fixing device of any of the above embodiments. The guide rail 50 is fixedly installed on the fixed platform 10. The guide rail 50 can be directly fixed on the fixed platform 10 or indirectly fixed on the fixed platform 10 through a connecting piece.

[0055] In this embodiment, a connector 13 is provided on the outer surface of the fixing platform 10, and the guide rail 50 is connected to the connector 13. The outer surface of the fixing platform 10 is provided with a plurality of mounting holes 11 for mounting the connector, which is secured in place using fasteners. The mounting holes 11 on the fixing platform 10 are distributed throughout the outer surface of the fixing platform 10. The selection of different mounting holes 11 can determine the installation position of the connector 13 according to different installation requirements. The connector 13 is generally approximately U-shaped and includes a connecting surface 131 to which the guide rail 50 is removably fixed.

[0056] Figure 6 This is an example of the installation state of a guide rail system installed on a steel surface with studs. In actual implementation, investigations and research at large-scale engineering equipment construction sites have found that connecting plates are welded to the steel sections before welding for pre-positioning. However, a large number of studs B are distributed on the steel surface A, forming an irregular installation surface, which causes problems in the fixation of the guide rail 50 and affects the positioning accuracy. In serious cases, it can even cause engineering accidents and bring huge economic losses to the enterprise. Using the guide rail system of this embodiment, it is only necessary to set a fixing plate 60 with two parallel and opposing mounting surfaces on the steel surface A. The second clamping modules 40 at both ends of the guide rail fixing device can be abutted against the fixing plate 60. The fixing plate 60 can be connected to the steel surface A by welding. The first inclined surface 31 and the second inclined surface 41 provided on the first clamping module 30 and the second clamping module 40 enable the fixing frame to be stably overlapped on the second clamping module 40, and have a component force on the second clamping module 40 that is perpendicular to the surface of the fixing plate 60, so that the fixation is more secure, so that the guide rail can be fixedly installed on the fixing platform 10 of the guide rail fixing device, and the fixed installation of the guide rail 50 is realized without being restricted and affected by irregular surface structures such as the bolts B, thereby ensuring the stability of the installation and the accuracy of the guide rail positioning. The material transfer is achieved by the transportation of the guide rail 50. Compared with the manual operation or machine lifting scheme, it has the advantages of high transportation efficiency, high precision and high safety. The guide rails of this guide rail system can be conventional conveying guide rails. The guide rails 50 of this embodiment include slide rails 51, sliders 52, drive devices 53 and transmission devices. The slide rails 51 are fixedly connected to the fixed platform 10. Pulleys 54 are provided on the sliders 52. The pulleys 54 are located on the upper and lower sides of the slide rails 51 respectively. The sliders 52 can slide along the slide rails 51 by rolling the pulleys 54. The drive device 53 is fixedly installed on the sliders 52. The transmission device includes a transmission gear. A rack structure 55 is provided on the slider 52. The transmission gear and the rack structure are engaged. The drive device 53 is used to drive the transmission gear to rotate. The drive device 53 can be a conventional motor, so that the rotation of the transmission gear can enable the slider 52 to move relative to the slider 52 along the extension direction of the rack structure 55, so that the object to be conveyed is connected through the slider 52, and the slider 52 slides along the slide rails 51, thereby realizing the conveying or reciprocating movement of the object.

[0057] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the embodiments described above. Various modifications may be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features within the embodiments may be combined with one another unless there is a conflict.
