Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of the body of construction machinery, in particular to a safety glass installation structure for the cab of a forestry machine of construction machinery. Background Technique
[0002] With the acceleration of the modernization process, construction machinery plays an increasingly important role in fields such as construction, mining, and infrastructure construction. These machines often work in complex and harsh environments, such as high temperature, dusty, and high-vibration conditions, which pose higher requirements for the working environment of operators. Among them, the cab, as the working space directly contacted by the operators, its safety and comfort directly affect work efficiency and personnel health.
[0003] Traditionally, the windows of construction machinery cabs mostly use tempered glass and are fixed to the cab frame by an adhesive method. Tempered glass is widely used because of its good impact resistance, but it also has obvious limitations: First, although tempered glass is more resistant to breaking than ordinary glass, it may still break when subjected to a strong impact, and the edges of the fragments are sharp, posing a safety hazard; Second, the installation method of adhesive fixation may become loose or even fall off during long-term use or when encountering strong vibrations, especially under the conditions of frequent operation and harsh environment of construction machinery, this risk is more prominent. Content of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the utility model provides a safety glass installation structure for the cab of a forestry machine of construction machinery to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A safety glass installation structure for the cab of a forestry machine of construction machinery includes a threaded seat fixing plate and a PC glass. A plurality of pressing plate type installation mechanisms are arranged at intervals at the connection between the threaded seat fixing plate and the PC glass. The pressing plate type installation mechanism includes an adhesive panel, glass adhesive, rubber pads, a glass pressing plate, a spherical nut, and an installation bolt. The threaded seat fixing plate is welded to the adhesive panel. The adhesive panel is adhered to the PC glass through the glass adhesive. A rubber pad is arranged between the PC glass and the glass pressing plate. The installation bolt sequentially passes through the threaded seat fixing plate, the adhesive panel, the PC glass, the rubber pad, and the glass pressing plate and is threadedly connected to the spherical nut to realize the fastening installation of the PC glass.
[0007] Preferably, the threaded seat fixing plate and the adhesive panel are welded by a full welding method, which can improve the overall strength and prevent water leakage.
[0008] Preferably, a plurality of through holes I are arranged on the adhesive panel.
[0009] Preferably, a plurality of second perforations are provided on the outermost side of the PC glass.
[0010] Preferably, a plurality of third perforations are provided on the outermost side of the glass pressing plate.
[0011] The utility model has the following beneficial effects compared with the prior art:
[0012] 1. Improve safety and reliability: By adopting the pressing plate type installation mechanism, the fixing method of the cab safety glass has been fundamentally improved; this structure not only enhances the fixing strength of the glass, reduces the risk of glass detachment caused by vibration or impact, but also ensures the stability and reliability of the connection through the combination of bolts, glass pressing plates and spherical nuts; in harsh working environments, such as emergencies like cave-ins or flying drive wheels, this design can more effectively protect the safety of the machine operator and reduce the occurrence of accidental injuries.
[0013] 2. Convenient maintenance and cost saving: The assembly process of the pressing plate type installation mechanism is simple and fast, and it is easy to disassemble and replace, which means that when the glass needs to be repaired or replaced, it can be completed quickly, greatly reducing the difficulty and time cost of after-sales maintenance; in addition, since the pressing plate material is easy to obtain and can even be handmade, the overall cost is relatively low, saving expenses for the enterprise.
[0014] 3. Optimize the working environment: The new installation structure not only improves safety, but also brings performance improvements in many other aspects; its good sound insulation and heat insulation effects help to reduce the noise level and temperature in the cab, providing a more comfortable working environment; at the same time, high light transmittance and flame retardancy ensure clear vision and fire safety, while strong impact resistance further enhances the protection of the machine operator; the improvement of these comprehensive performances not only improves work efficiency, but also ensures the physical and mental health of the operator.
