Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. The components of the embodiments of the utility model described and shown in the drawings can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the application provided in the drawings is not intended to limit the scope of the claimed application, but only represents selected embodiments of the application. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative labor belong to the scope of protection of the utility model.

[0023] EMBODIMENT

[0024] The utility model provides a kind of protective fence for automatic escalator maintenance, such as Figures 1-4As shown in the figure, it includes a first fence structure, and the first fence structure includes two first mounting posts 1 arranged in pairs and a telescopic first protection structure 2. The first mounting post 1 is a hollow tubular structure with a rectangular cross-section. The first protection structure 2 is installed between the two first mounting posts 1, and second fence structures are rotatably provided on the first mounting posts 1. In this way, the two second fence structures are located on both sides of the first fence structure to form a "匚"-shaped structure, which can enclose a maintenance area at the place to be maintained. The first fence structure and the second fence structure are both compressible, and do not occupy much space during later handling and storage, which is convenient for the user to carry independently. Clamping structures are installed on the telescopic ends of the second fence structures. The clamping structures provided can detachably connect the second fence structures to the crossbars or side walls in the maintenance area, preventing the enclosure area formed by the above structures from being damaged due to being moved artificially, so that the above structures cannot play their due warning role. An adjusting structure for adjusting the deflection angle of the second fence structure is provided on the first mounting post 1. By adjusting the angle between the first mounting post 1 and the second fence structure through the adjusting structure, the operation area of the enclosure area formed by the above structures can be increased. The adjusting structure provided also plays a role in connecting the first fence structure and the second fence structure, preventing the above structures from being separated during use.

[0025] In some technical solutions of the present invention, the first protection structure 2 is in a scissor shape, and both sides of the first protection structure 2 are slidably connected to the two first mounting posts 1 respectively. After the scissor-shaped first protection structure 2 is connected to the two first mounting posts 1, the structural strength of the first guardrail structure can be increased, preventing the first guardrail structure from being skewed or toppled when acting alone.

[0026] In some technical solutions of the present invention, the first protection structure 2 includes a first protection rod and a first swing rod 10. The two ends of the first protection rod are respectively hinged to the side walls of the two first mounting posts 1, and the two ends of the first swing rod 10 are respectively slidably arranged on the side walls of the two first mounting posts 1, and the first protection rod and the first swing rod 10 are cross-connected and then hinged to each other. After the first protection rod and the first swing rod 10 are hinged to each other and then connected to the two first mounting posts 1, a relatively rigid connection relationship can be formed, improving the structural strength of the first guardrail structure, preventing the first guardrail structure from being skewed or toppled when acting alone.

[0027] The scissor-shaped structures formed by the first protection rod and the second swing rod can be multiple groups, and the multiple groups of scissor-shaped structures are sequentially connected to each other. In this way, the length of the first fence structure can be increased, and the use range of this structure can be improved.

[0028] In some technical schemes of the utility model, two second installation columns 4 and telescopic second protection structure 3 of the second fence structure are arranged in pairs, and the second protection structure 3 is installed between the two second installation columns 4. The second installation column 4 is a hollow tubular structure, and the cross section is rectangular.

[0029] In some technical schemes of the utility model, the second protection structure 3 is the same as the first protection structure 2 in structure. The above structure can be ensured to be low in difficulty in later production, the first protection structure 2 and the second protection structure 3 can be replaced with each other, and later assembly is facilitated.

[0030] In some technical schemes of the utility model, the clamping structure comprises a mounting seat 6 and a tension spring 11, the mounting seat 6 is fixed on the side wall of the second installation column 4 through bolts. Two clamping arms 5 are hingedly connected to the mounting seat 6 through a pin shaft, and the clamping arms 5 are arc-shaped or straight plate-shaped. The tension spring 11 is installed between the two clamping arms 5. In the initial state, the tension spring 11 is placed between the two clamping arms 5 in a natural compression state. When the two clamping arms 5 are pulled away from each other by the operator, the clamping arms 5 are placed on both sides of the horizontal rod or the side wall in the area to be overhauled, so that the second protection structure 3 is temporarily fixed, and the problem that the enclosed area formed by the first guardrail structure and the second guardrail structure is damaged is prevented. The problem that the second guardrail structure is inclined or tilted during use is also prevented.

[0031] In some technical schemes of the utility model, the adjusting structure comprises an adjusting sleeve, a plurality of rotating rings 12 connected with the first installation column 1 and the second installation column 4 are rotationally arranged on the side wall of the adjusting sleeve, the number of the rotating rings 12 is at least four, two of the rotating rings 12 are fixedly connected with the first installation column 1 through welding, and the other two rotating rings 12 are fixedly connected with the second installation column 4 through welding. A support structure is installed on the adjusting sleeve.

[0032] Preferably, the rotating ring 12 is provided with a notch, so that the rotating ring 12 can be clamped on the outer side wall of the adjusting sleeve through the notch, and the above structure can be easily disassembled for maintenance later.

[0033] In some technical solutions of this utility model, the support structure includes a stable seat 8 installed at the bottom of the adjusting sleeve, and an installation groove is provided on the side wall of the stable seat 8. A support seat 7 is rotatably mounted in the installation groove via a pin. The support seat 7 is flush with the bottom surface of the stable seat 8. After the support seat 7 is mounted in the installation groove, the stable seat 8 and the support seat 7 are perpendicular to each other, which can increase the contact area between the above structure and the ground, improve the stability of the first fence structure and the second fence structure, and facilitate later storage. An adjusting rod 13 connected to the support seat 7 is rotatably mounted in the adjusting sleeve, and a threaded sleeve 14 threadedly connected to the adjusting rod 13 is installed in the adjusting sleeve. The adjusting rod 13 can prevent the support seat 7 from deflecting arbitrarily in the installation groove, and its direct purpose is to improve the stability of the above structure.

[0034] Preferably, a wear-resistant layer is installed at the bottom of the support base 7. The wear-resistant layer is a rubber sheet, which can increase the friction when the above structure contacts the ground and improve the stability of the above structure when it is deployed.

[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
