Description

Technical Field

[0001] The utility model relates to the technical field of enclosures, in particular to a warning fence used for elevator maintenance. Background Art

[0002] Fence devices, namely guardrail devices, play the role of protection and warning, and prevent potential safety hazards. Ladders have become a common device for climbing high-rise buildings. Elevators generally need to be regularly inspected and maintained. In order to avoid injuries caused by non-staff during maintenance, protective fences need to be set up during maintenance, and guardrails are used to enclose a certain space to form an isolation area;

[0003] However, during the elevator maintenance process, since the width of each elevator entrance is different and the conventional enclosure device is assembled from multiple sets of baffles, its installation is cumbersome and its stability is poor. It is very easy to move and tip over, which can easily affect the enclosure effect of the elevator under maintenance and increase the probability of safety hazards.

[0004] In view of the technical defects in this aspect, a solution is now proposed. Utility Model Content

[0005] The purpose of the utility model is to adjust the opening and closing angles of the main baffles and the side baffles according to the specific width of the elevator entrance by setting two groups of main baffles, side baffles, cross plates and pressure pieces, thereby ensuring the stability of the enclosure structure and avoiding complicated installation procedures, thereby improving the maintenance efficiency of the elevator and the use effect of the enclosure.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a warning fence for elevator maintenance, comprising two groups of main baffles, one end of the opposite surfaces of the two groups of main baffles are hingedly installed by hinges, and the two are symmetrically arranged, the top surface of the main baffle is provided with a long groove, and the ends of the two groups of long grooves close to the hinges are slidably connected with round shafts, the top surfaces of the two groups of round shafts are jointly provided with a horizontal plate, and the two ends of the horizontal plate are curved structures, and the two groups of round shafts are fixedly installed at the two ends of the bottom surface of the horizontal plate.

[0007] Furthermore, a vertical groove is provided at the center of the front end surface of the two groups of main baffles near the lower end, and the bottom of the vertical groove is an open structure. The inner walls on both sides of the vertical groove are hinged with a bottom plate at the bottom end, and a clamping groove is provided at the center of the top surface of the bottom plate and the center of the inner wall of the vertical groove. An inclined support rod is clamped between the two groups of the clamping grooves.

[0008] Furthermore, grooves are formed at the ends of the two sets of main baffles away from each other, and side baffles are hinged inside the grooves. Pullies are provided at the ends of the side baffles extending to the bottom surface away from the grooves, and the pulleys are in contact with the ground.

[0009] Furthermore, the centers of the top surfaces of the two groups of side baffles are provided with limiting grooves, a vertical pole is hinged inside one group of the limiting grooves, and a sliding frame is sleeved on the top of the vertical pole, and a pressure block is fixedly installed on one side of the sliding frame.

[0010] Furthermore, pressure pieces are evenly spaced from the front ends of the two groups of side baffles on opposite sides, and the left and right pressure pieces are mirror-symmetrical with respect to the central axes of the two groups of main baffles.

[0011] Furthermore, the pressing member includes a convex insert, which is arranged through the front end frame of the side baffle, and a suction cup is fixedly installed at one end of the convex insert, and the outer wall of the convex insert is located between the suction cup and the side baffle and is jointly wound with a spring coil.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model sets two sets of main baffles, side baffles and cross plates, pushes the cross plate forward, and the circular shaft slides inside the long groove. The farther the cross plate is pushed, the smaller the angle formed by the folding of the two sets of main baffles becomes, until the opening size of the angle of the two sets of main baffles matches the width of the elevator entrance. The two sets of side baffles change according to the change of the positions of the two sets of main baffles. The two sets of side baffles are close to the two side walls of the elevator entrance respectively, so as to adjust the opening and closing angle of the main baffle according to the width of the elevator entrance, thereby ensuring the stability of the enclosure structure, reducing the complex installation structure, and improving the maintenance effect of the elevator.

[0014] 2. The utility model sets uprights, sliding frames and pressure pieces, etc. After the position of the side baffles is determined, the uprights are flipped to force the sliding frames and the pressure blocks to press against the sides of the other set of side baffles, forcing the two sets of side baffles to be stably reinforced, and the pressure pieces are used to elastically press against the walls. This structure can further reinforce the enclosure structure while reducing the damage to the elevator entrance wall caused by hard pressure, thereby further improving the use efficiency of the enclosure.

DETAILED DESCRIPTION

[0021] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1: Please refer to Figure 1 - Figure 4 As shown, a warning fence for elevator maintenance includes two sets of main baffles 1, one end of the opposite surface of the two sets of main baffles 1 is hingedly installed by hinges, and the two sets of main baffles 1 are symmetrically arranged, the top surface of the main baffle 1 is provided with a long groove 2, and the ends of the two sets of long grooves 2 near the hinge are slidably connected with round shafts 3, the top surfaces of the two sets of round shafts 3 are jointly provided with a horizontal plate 4, and the two ends of the horizontal plate 4 are curved surface structures, and the two sets of round shafts 3 are fixedly installed at the two ends of the bottom surface of the horizontal plate 4; the front end centers of the two sets of main baffles 1 are close to each other. A vertical groove 5 is provided near the lower end, and the bottom of the vertical groove 5 is an open structure. The inner walls on both sides of the vertical groove 5 are hinged with a bottom plate 6 at the bottom end, and a clamping groove 7 is provided at the center of the top surface of the bottom plate 6 and the center of the inner wall of the vertical groove 5. An inclined stopper 8 is clamped between the two groups of clamping grooves 7. A groove 9 is provided at the end of the two groups of main baffles 1 away from each other, and a side baffle 10 is hinged inside the groove 9. A pulley 11 is provided at the end of the side baffle 10 extending to the bottom surface away from the groove 9, and the pulley 11 is in contact with the ground;

[0023] The two sets of main baffles 1 are placed at the elevator entrance and adjusted according to the width of the elevator entrance. When adjusting, it is only necessary to push the cross plate 4 forward, and the two sets of circular shafts 3 slide inside the long groove 2. The farther the cross plate 4 is pushed, the smaller the angle formed by the folding of the two sets of main baffles 1 is, until the opening size of the angle of the two sets of main baffles 1 is adapted to the width of the elevator entrance. The two sets of side baffles 10 are changed according to the change of the positions of the two sets of main baffles 1, until the two sets of side baffles 10 are respectively close to the two side walls of the elevator entrance. After the positions of the main baffles 1 and the side baffles 10 are determined, the bottom plate 6 can be flipped out from the inside of the vertical groove 5 and made perpendicular to the main baffle 1 at ninety degrees, and then the push rod 8 is obliquely inserted between the two sets of card slots 7 for limitation, and a stable support is formed for the two sets of main baffles 1. The structure utilizes the adjustment of the triangular structure to adapt to the width change of the elevator entrance, ensures the stability of the enclosure structure, reduces complex installation steps, and improves the elevator maintenance effect.

[0024] Example 2: Please refer to Figure 1 , Figure 2 and Figure 4 As shown, the center of the top surface of the two groups of side baffles 10 is provided with a limiting groove 12, one of the limiting grooves 12 is hinged with a vertical rod 13, and the top of the vertical rod 13 is sleeved with a sliding frame 14, and a pressure block 15 is fixedly installed on one side of the sliding frame 14. The two groups of side baffles 10 are located at the front end of the opposite surfaces and are evenly spaced. The left and right pressure pieces 16 are mirror-symmetrical with respect to the central axis of the two groups of main baffles 1. The pressure piece 16 includes a convex insert 161, which is arranged through the front end frame of the side baffle 10, and a suction cup 162 is fixedly installed on one end of the convex insert 161. The outer wall of the convex insert 161 is located between the suction cup 162 and the side baffle 10 and is jointly wound with a spring group coil 163;

[0025] After the positions of the two groups of side baffles 10 are determined, the vertical rod 13 is flipped to force one end of the vertical rod 13 to be clamped in the corresponding limit groove 12. According to the spacing between the two groups of side baffles 10, the position of the sliding frame 14 is slid to force the pressing block 15 to press against the side of one group of side baffles 10, thereby realizing the limitation between the two groups of side baffles 10, and the two groups of side baffles 10 are respectively close to the walls on both sides of the elevator entrance, the suction cups 162 are against the corresponding walls, and move to the convex plug-in cylinder 161, and the spring coil 163 is compressed. This structure can not only reduce the damage to the wall at the elevator entrance caused by hard pressure, but also tighten the connection between the side baffle 10 and the wall at the elevator entrance, thereby further improving the use efficiency of the enclosure.

[0026] Working principle: When the utility model is used, firstly, two sets of main baffles 1 are placed at the elevator entrance, and then adjusted according to the width of the elevator entrance, and the horizontal plate 4 is pushed forward, and the two sets of round shafts 3 slide inside the long groove 2, and the farther the horizontal plate 4 is pushed, the smaller the angle formed by the folding of the two sets of main baffles 1 is, until the opening size of the angle of the two sets of main baffles 1 is adapted to the width of the elevator entrance, and the two sets of side baffles 10 are changed according to the change of the positions of the two sets of main baffles 1, until the two sets of side baffles 10 are close to the two side walls of the elevator entrance respectively;

[0027] After the positions of the main baffle 1 and the side baffle 10 are determined, the vertical rod 13 is first flipped to force one end of the vertical rod 13 to be clamped in the corresponding limit groove 12. According to the spacing between the two groups of side baffles 10, the position of the slide frame 14 is slid to force the pressure block 15 to press against the side of one group of side baffles 10, thereby realizing the limitation between the two groups of side baffles 10. The two groups of side baffles 10 are respectively close to the walls on both sides of the elevator entrance, and the suction cups 162 elastically press against the corresponding walls; then the bottom plate 6 is flipped out from the vertical groove 5 and is perpendicular to the main baffle 1 at 90 degrees, and then the push rod 8 is obliquely inserted between the two groups of card grooves 7 for limitation, and forms a stable support for the two groups of main baffles 1 to form a stable enclosure structure.
