Description

Technical Field

[0001] The utility model relates to the technical field of highway bridge safety equipment, in particular to an improved escalator. Background Art

[0002] As the mileage of my country's roads continues to increase, extra-large bridges and elevated roads continue to appear. The longer the bridge, the higher the probability of a traffic accident on the bridge. Since there is no off-road safe haven on the bridge, passengers lack space to escape after an accident, which can easily lead to secondary accidents and cause greater harm to the passengers.

[0003] For example, the authorization announcement number CN219032910U is a kind of escape platform for bridges. The above document designs an escape platform. When a traffic accident occurs on the bridge, the driver and passengers can enter the escape platform for temporary escape, even if they evacuate the accident scene, thereby effectively preventing secondary accidents. People can enter the escape platform as long as they cross the bridge. However, during the use of the escape platform for bridges in the above document, due to the high height of the general road guardrail or bridge, especially the guardrail of the high-speed elevated road section, the personnel tell the elevated guardrail section to increase the guardrail when entering the escape platform, and the driver and the accompanying personnel of the vehicle in the accident are prone to injury after the accident, making it difficult for the personnel to enter the escape platform, so it is not convenient to use the escape platform. There are also some escalators set on the guardrails of the bridge, but because the escalator is heavy, it is also inconvenient to retract the ladder, especially after the personnel enter the platform, it is more difficult to retract the ladder. Therefore, it is very necessary to design an escalator that is suitable for guardrails and can be retracted with less effort. Utility Model Content

[0004] The utility model aims to solve the problem that it is difficult for injured people to climb up the platform and the problem that people are easily affected by the weather environment and slip when using the escalator, so that people suffer secondary injuries.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An improved escalator comprises a mounting base installed on the top of a bridge guardrail, the top of the bridge guardrail is fixedly connected to the mounting base by bolts, the top two sides of the mounting base are rotatably connected to a plurality of connecting rods by pins, the right side of the connecting rod is rotatably connected to a first connecting frame by a pin, the bottom of the first connecting frame is rotatably connected to a second connecting frame by a pin, the side end of the first connecting frame is fixedly connected to a support base, and the inner ends of the first connecting frame on both sides and the second connecting frames on both sides are respectively fixedly connected to a plurality of ladder steps.

[0007] Preferably, a limiting structure is provided inside the support seat, and the limiting structure includes a round block, the middle part of the round block is rotatably connected to the support seat, the front end of the round block is fixedly connected to the protrusion, the outer wall of the protrusion is slidably connected to the L-shaped block, the interior of the L-shaped block is fixedly connected to one end of the second spring, the other end of the second spring is fixedly connected to the sliding rod, the outer wall of the sliding rod is slidably connected to the L-shaped block, the left end of the sliding rod is fixedly connected to the support seat, the right side of the L-shaped block is fixedly connected to the sliding block, and the outer wall of the sliding block is slidably connected to the limiting block.

[0008] Preferably, the middle portion of the outer wall of the limiting block is slidably connected to the support seat, and the top portion of the outer wall of the limiting block is snap-connected to the connecting block.

[0009] Preferably, an arc-shaped introduction section is provided at the top of the limit block on the side facing away from the support seat, and when the first connecting frame is flipped out toward the inner side of the guardrail of the bridge, the arc-shaped introduction section gradually bends downward from the center of the limit block toward the direction away from the support seat.

[0010] The arrangement of the arc-shaped introduction section makes it easier to snap-fit ​​the limit block and the connecting block when the second connecting frame is folded, without the need to rotate the round block to press the limit block down and then snap it into the connecting block. This makes operation convenient, and the second connecting frame can be snap-fitted and fixed relative to the first connecting frame after being folded back and folded against one side of the first connecting frame.

[0011] Preferably, a slide rail is provided on the mounting seat corresponding to the connecting rod, a sliding member which can slide along the slide rail is provided in the slide rail, and the connecting rod is hinged to the sliding member.

[0012] Preferably, after the second connecting frame is folded and overlapped with the first connecting frame, the second connecting frame is arranged on the inner side or the top of the slide rail.

[0013] Preferably, an opening is provided on the inner side of the slide rail for the connecting rod to cooperate with and slide on the sliding member.

[0014] Through the cooperation of the slide rail, the sliding member and the connecting rod, the folded escalator is closer to the outside of the bridge guardrail as a whole, and can be pushed a little distance to the inside of the guardrail to ensure the lowering of the entire escalator when it is needed. In order to ensure the stability of the escalator when in use, the escalator has a certain weight, and the entire escalator is not too light. When the personnel in the shelter platform need to retract the escalator, after pulling the first connecting frame a little distance to the outside of the guardrail, the first connecting frame can be close to the inner edge of the top of the guardrail to form a front fulcrum, and due to the limitation of the slide rail, the sliding member and the connecting rod, a movable rear fulcrum is formed, so that when the uppermost ladder step of the first connecting frame is continued to be pulled, it will be relatively labor-saving. Only one direction is needed to pull the first connecting frame to make the first connecting frame relatively easy to lift up and move outside the guardrail. When the first connecting frame is lifted and recovered in place, it will be relatively stably set on the top of the guardrail, and then the second connecting frame and the first connecting frame can be folded back and overlapped in sequence.

[0015] Preferably, the top right side of the second connecting frame is fixedly connected to the vertical block, and the bottom right side of the second connecting frame is fixedly connected to the second supporting block.

[0016] Preferably, the left side of the top of the first connecting frame is fixedly connected to the first supporting block, and the side end of the second connecting frame is fixedly connected to the connecting block.

[0017] The improved escalator proposed by the utility model has the following beneficial effects:

[0018] 1. By pulling the first connecting frame, the first supporting block is pressed against the right end of the guardrail of the bridge, and the user turns the round block to rotate clockwise, and the round block drives the protrusion to move in a circle, and the round block drives the L-shaped block to slide along the outer wall of the slide rod, and at the same time drives the second spring to compress, so that the L-shaped block drives the slider to move to the left, and the slider drives the limit block to move downward, and then the second connecting frame is pulled to make the second connecting frame rotate along the first connecting frame to support the second connecting frame. The personnel climb to the inside of the refuge platform through the handrails on both sides of the mounting seat, and then reset the first connecting frame and the second connecting frame to wait for rescue, thereby avoiding the situation where it is difficult for personnel to climb the platform due to injuries.

[0019] 2. Through the cooperation of the slide rail, the sliding part and the connecting rod, the escalator after folding is closer to the outside of the bridge guardrail as a whole, and the escalator is relatively labor-saving and convenient to retract, and is easy to operate.

[0020] 3. This application is simple and convenient to operate, and is safer and more stable to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The utility model is further described below in conjunction with the accompanying drawings:

[0030] Embodiment 1:

[0031] See attached Figure 1-6 In the present embodiment, an improved escalator includes a mounting base 2 installed on the top of a guardrail 1 of a bridge, the top of the guardrail 1 is fixedly connected to the mounting base 2 by bolts, the top sides of the mounting base 2 are rotatably connected to a plurality of connecting rods 5 by pins, the right side of the connecting rod 5 is rotatably connected to a first connecting frame 6 by a pin, the bottom of the first connecting frame 6 is rotatably connected to a second connecting frame 7 by a pin, the side end of the first connecting frame 6 is fixedly connected to a support base 11, and the inner ends of the first connecting frames 6 on both sides and the second connecting frames 7 on both sides are fixedly connected to a plurality of ladder steps 13 respectively.

[0032] Embodiment 2:

[0033] The difference from the above embodiment is that a limiting structure 4 is arranged inside the support seat 11, and the limiting structure 4 includes a round block 4a1, the middle part of the round block 4a1 is rotatably connected to the support seat 11, the front end of the round block 4a1 is fixedly connected to the protrusion 4a2, the outer wall of the protrusion 4a2 is slidably connected to the L-shaped block 4a3, and the outer wall of the round block 4a1 is processed with friction lines, which increases the friction between the round block 4a1 and the user's hand, making it convenient for the user to turn the round block 4a1 clockwise, the round block 4a1 drives the protrusion 4a2 to move in a circle, the round block 4a2 drives the L-shaped block 4a3 to slide along the outer wall of the slide rod 4a5, and at the same time drives the second spring 4a4 to compress, so that the L-shaped block 4a3 drives the slider 4a6 to move left, and the slider 4a6 drives the limiting block 4a 7 moves downward, and then pulls the second connecting frame 7 to make the second connecting frame 7 rotate along the first connecting frame 6, so as to press the second supporting block 10 against the right end of the guardrail of the bridge, and support the second connecting frame 7; the interior of the L-shaped block 4a3 is fixedly connected to one end of the second spring 4a4, the other end of the second spring 4a4 is fixedly connected to the sliding rod 4a5, the outer wall of the sliding rod 4a5 is slidably connected to the L-shaped block 4a3, the left end of the sliding rod 4a5 is fixedly connected to the supporting seat 11, the right side of the L-shaped block 4a3 is fixedly connected to the sliding block 4a6, the outer wall of the sliding block 4a6 is slidably connected to the limit block 4a7, the middle part of the outer wall of the limit block 4a7 is slidably connected to the supporting seat 11, and the top of the outer wall of the limit block 4a7 is clamped with the connecting block 12.

[0034] In this embodiment, the limiting structure 4 may also include a clamping block 4b1, the outer ends of the clamping blocks 4b1 on both sides are fixedly connected to the support seat 11, and the outer wall of the clamping block 4b1 is slidably connected to the limiting block 4a7. The limitation between the clamping block 4b1 and the sliding groove of the limiting block 4a7 makes the sliding of the limiting block 4a7 smoother.

[0035] Embodiment 3:

[0036] The difference from the above embodiment is that an arc-shaped introduction section 4a71 is provided on the top of the limit block 4a7 facing away from the support seat 11. When the first connecting frame 6 is flipped out to the inner side of the guardrail of the bridge, the arc-shaped introduction section gradually bends downward from the center of the limit block toward the direction away from the support seat 11.

[0037] By setting the arc-shaped introduction section, the limit block 4a7 can be more conveniently connected with the connecting block 12 when the second connecting frame 7 is folded, without the need to rotate the round block 4a1 to press the limit block down and then insert it into the connecting block. This makes the operation convenient. After the second connecting frame is folded back and folded against one side of the first connecting frame 6, it is fixed relative to the first connecting frame 6.

[0038] Embodiment 4:

[0039] The difference from the above embodiment is that a slide rail 21 is provided on the mounting seat corresponding to the connecting rod, a sliding member 22 is provided inside the slide rail and can slide along the slide rail, and the connecting rod 5 is hinged to the sliding member 22. Through the cooperation of the slide rail, the sliding member and the connecting rod, the escalator after folding is closer to the outside of the guardrail of the bridge, and can be pushed a little distance inside the guardrail to ensure the lowering of the entire escalator when it is needed. After the second connecting frame 7 is folded and overlapped with the first connecting frame 6, the second connecting frame 7 is arranged on the inside or top of the slide rail 21.

[0040] In order to ensure the stability of the escalator when in use, the escalator has a certain dead weight and the entire escalator is not too light. When the personnel in the escape platform need to retract the escalator, they pull the first connecting frame 6 a little distance to the outside of the guardrail and then the first connecting frame can be close to the inner edge of the top of the guardrail to form a front fulcrum, and due to the limitation of the slide rail, the sliding member and the connecting rod, a movable rear fulcrum is formed, so that when the uppermost step of the first connecting frame is continued to be pulled, it will be relatively labor-saving. Only the first connecting frame needs to be pulled in one direction to make the first connecting frame relatively easily lifted upward and moved outside the guardrail. When the first connecting frame is lifted and recovered into place, it will be more stably arranged on the top of the guardrail, and then the second connecting frame 7 and the first connecting frame can be folded back and overlapped in sequence.

[0041] Embodiment 5:

[0042] The difference from the above embodiment is that the inner side of the slide rail 21 is provided with an opening for the cooperation and sliding of the connecting rod 5 and the sliding member 22. A slide rail is provided on each side of the escalator, and the inner sides of the two slide rails facing each other are open, so that most of the components of the escalator are gathered between the two slide rails after the escalator is folded, and the integrity is stronger. The second connecting frame can also block the inner side opening of the slide rail, so that the slide rail has a longer service life.

[0043] Embodiment 6:

[0044] The difference from the above embodiment is that the top right side of the second connecting frame 7 is fixedly connected to the vertical block 9, and the bottom right side of the second connecting frame 7 is fixedly connected to the second supporting block 10. The first connecting frame 6 is pulled, so that the first connecting frame 6 drives the connecting rod 5 to rotate and the first connecting frame 6 rotates along the connecting rod 5, so that the first supporting block 8 is tightly pressed against the right end of the guardrail of the bridge, thereby supporting the first connecting frame 6. The top left side of the first connecting frame 6 is fixedly connected to the first supporting block 8, and the side end of the second connecting frame 7 is fixedly connected to the connecting block 12.

[0045] When a person uses the escalator to enter the escape platform, he pulls the first connecting frame 6, so that the first connecting frame 6 drives the connecting rod 5 to rotate. At the same time, the first connecting frame 6 rotates along the connecting rod 5, so that the first supporting block 8 is tightly pressed against the right end of the guardrail of the bridge, thereby supporting the first connecting frame 6. The user turns the round block 4a1 clockwise, and the round block 4a1 drives the protruding block 4a2 to move in a circle. The round block 4a2 drives the L-shaped block 4a3 to slide along the outer wall of the sliding rod 4a5, and at the same time drives the second spring 4a4 to compress, so that the L-shaped block 4a3 drives the slider 4a6 to move to the left, and the slider 4a6 drives the limit block 4a7 to move downward, and then pulls the second connecting frame 7, so that the second connecting frame 7 rotates along the first connecting frame 6, thereby pressing the second supporting block 10 against the right end of the guardrail of the bridge to support the second connecting frame 7. People climb to the inside of the refuge platform through the handrails on both sides of the mounting seat 2, and then reset the first connecting frame 6 and the second connecting frame 7 to wait for rescue, avoiding the situation where it is difficult for people to climb the platform due to injuries.
