Description

Technical Field

[0001] The utility model relates to the technical field of rail vehicle platform safety protection, in particular to a multi-section equidistant fixing device for a rope-shaped fence of a platform safety protection door. Background Art

[0002] At present, most of the platforms of various railway bureaus are open-style designs without protective measures. When passengers are waiting for the train, there are only passenger attendants patrolling and supervising on the platform. According to the "Railway Passenger Transport Management Rules", there are an average of 1.5 passenger attendants on each platform, and the train has at least 8 carriages and at most 16 carriages. If there is a train coming from only one side, 3 people can supervise a train at the same time; if there are trains coming from both sides at the same time, there are 1.5 people on one side, 8 or 16 carriages, and there are hundreds or thousands of people waiting for the train, distributed in multiple carriages. It is impossible for three people to supervise them all, and passengers may fall off the platform, which is an unsafe factor. This not only brings inconvenience to other passengers, but also has a great impact on the station.

[0003] At present, some railway stations have begun to try to use platform rope fence protection gates to provide passengers with platform safety protection. The general structure of such platform rope fence protection gates is that multiple sliding parts drag multiple ropes to form a fence. Driven by the motor, the ropes rise to the top, and passengers can board the train smoothly. The rope fence is in a lowered state as a whole, and passengers are blocked on the inside of the platform. The rope fence is at the top, and the ropes are close to each other. The rope fence is lowered, and the ropes are arranged at equal intervals.

[0004] See also Figure 1 As shown, the current platform safety protection door ropes are arranged at equal intervals in a manner that each slider 20 slides down the slide rail 10 by its own weight and stops when it encounters a limit block 40. This method has a huge drawback, that is, passengers can individually lift up other sliders 20 except the bottom one as a whole, increasing the spacing of the rope-shaped fence ropes 30, so that people can pass through, which brings unsafe factors. Utility Model Content

[0005] In view of the problems and shortcomings existing in the prior art, the utility model provides a multi-section equidistant fixing device for the rope fence of the platform safety protection gate. The purpose is to achieve rigid connection and fixation between each group of sliding parts after the descending ropes of the rope fence are arranged at equal intervals, so as to prevent people from intentionally pulling the ropes and crossing the rope fence to cause injuries and accidents.

[0006] The technical solution of this utility model is as follows:

[0007] A multi-section equidistant fixing device for a platform safety protection door rope fence comprises a vertically arranged guide rail, a plurality of sliding assemblies are arranged vertically at intervals on the guide rail, the sliding assemblies are connected to the rope guardrail assemblies, and the rope guardrail assemblies are driven up and down by a driving mechanism, and are positioned by a positioning piece on the guide rail;

[0008] The sliding assembly includes a sliding member and a connecting member, the sliding member is slidably matched with the guide rail, the inner side of the connecting member is connected to the sliding member, and the outer side of the connecting member is connected to the rope guardrail assembly;

[0009] A limiting mechanism is provided between adjacent sliding components, which is used to drive the adjacent sliding component below to move upward; the limiting mechanism includes a limiting hook lock arranged on the lower connecting member and a limiting member arranged on the upper connecting member, and the limiting hook lock can be locked with the limiting member when moving upward and unlocked with the limiting member when moving downward.

[0010] In a specific embodiment, the rope guardrail assembly includes two symmetrically arranged guardrail panels and a rope in the middle, the guardrail panels are fixedly connected to the connecting piece by bolts, and a plurality of ropes are arranged in parallel and spaced along the height direction of the guardrail panels. In the specific embodiment, there are four ropes, which are connected in parallel and spaced up and down between the guardrail panels on both sides.

[0011] The upper end of the limit hook lock is connected to the connecting piece of the upper sliding assembly in the adjacent sliding assembly, and the lower end is provided with a lock hook. The limit piece is fixed on the connecting piece of the lower sliding assembly, and a blocking hook is provided on the limit piece to cooperate with the lock hook. Specifically, the lock hook is a right-angle hook with one side vertical and the other side horizontal and extending in the direction of the guardrail board, and the blocking hook is a right-angle hook staggered and perpendicular to it, and its bottom surface overlaps with the top surface of the lock hook.

[0012] When the upper sliding assembly in the sliding assembly is lifted, the limit hook lock on the connecting piece connected to the upper sliding assembly moves upward accordingly. When it moves to the limit piece position on the connecting piece of the lower sliding assembly, the top surface of the lock hook of the limit hook lock overlaps with the bottom surface of the limit piece, and drives the limit piece to move upward, while driving the connecting piece on the lower sliding assembly connected to the limit piece to move upward. At this time, the sliding assembly located below moves upward at the same time as the adjacent sliding assembly above it, thereby driving the guardrail assembly to move upward together, thereby preventing passengers from pulling the rope guardrail assembly upward through a group of sliding assemblies and passing through the platform safety protection door, thereby avoiding accidents such as casualties.

[0013] In a specific embodiment, the driving mechanism includes a motor and a synchronous belt transmission mechanism, the synchronous belt transmission mechanism includes a synchronous belt and a transmission assembly, the synchronous belt is connected to the connecting member of the lowest sliding assembly and drives it to move up and down, thereby driving the rope guardrail assembly to move up and down. A limit sensor is provided on the guide rail, and a sensing member is provided on the synchronous belt to limit the upper and lower limit positions of the rope guardrail assembly.

[0014] In a specific embodiment, a plurality of positioning members are arranged at intervals along the height direction of the guide rail, and the number of positioning members is equal to the number of sliding assemblies, which are used to limit the lower limit position of the sliding assembly moving downward. When the safety protection door is closed, the sliding assembly drives the rope guardrail assembly to fall freely under the action of gravity, and the position of the sliding assembly is limited by the limiting members respectively, so that the sliding assembly stops on the guide rail at even intervals up and down, so that the rope guardrail assembly is evenly arranged up and down, which plays a protective role and prevents passengers from crossing.

[0015] In a specific embodiment, the sliding assembly includes two sliding members spaced apart from each other, and the two sliding members are fixedly connected together by a connecting member. The two sliding members spaced apart from each other increase the stability of the sliding assembly, so that the length of the link plate can be extended as required.

[0016] In this embodiment, the number of sliding components is three groups. Three groups of rope guardrail components are connected, and each group of rope guardrail components is provided with four ropes evenly spaced up and down, so that the platform safety guardrail can play an anti-slip role, and has a simple structure and low cost.

[0017] The beneficial effects of the utility model are:

[0018] 1) The utility model sets a limit mechanism between the sliding components so that the adjacent sliding components can be linked into a rigid whole when moving upward, and cannot move upward individually, so that the multiple rope guardrail components connected thereto are also mutually connected into a whole when moving upward, and cannot move upward individually, thereby preventing two adjacent rope guardrail components from being separated by a distance too large so that passengers can pass through. Therefore, the application of the utility model can prevent passengers from passing through the platform safety protection door, avoiding the occurrence of personal injury accidents caused by it.

[0019] 2) The limiting mechanism includes a limiting hook lock and a limiting member. The limiting hook lock and the limiting member have a simple structure, are easy to maintain, and have a low manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS
