Description

Technical Field

[0001] This utility model relates to the field of sheet metal technology, specifically to a railway pedestrian walkway. Background Technology

[0002] Currently, pedestrian walkways and maintenance access routes in railways and light rail systems commonly use concrete slabs or steel gratings. Concrete slabs are mounted on supports by their own weight, while steel gratings are mounted on supports by their own weight or by binding. Neither concrete slabs nor steel gratings have locking devices to secure them to the supports, making them prone to being lifted or shaken off during windy weather or when trains pass, potentially causing safety accidents.

[0003] The difficulty in installing cement boards or iron gratings on new lines and maintaining them on old lines lies in the long railway lines, the heavy weight and large volume of cement or iron products, the troublesome transportation and hoisting, and the long time, manpower, and mechanical equipment required for installation.

[0004] Cement products are not resistant to acids and alkalis and are prone to water absorption. Their performance is greatly affected by weather changes, and they have a large thermal expansion rate. Due to their internal moisture content, their freeze-thaw resistance is poor.

[0005] Iron gratings require different coatings for corrosion protection, which places high demands on the coatings and necessitates continuous maintenance, resulting in significant maintenance costs.

[0006] Currently, cement or iron products are heavy, which poses high structural requirements for bridges and roadbeds. They cannot achieve lightweighting, which increases the overall investment cost. Utility Model Content

[0030] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0031] Example 1

[0032] like Figures 1-6 As shown, this embodiment provides a railway walking board, including a walking board body 1. The walking board body 1 is made of molding compound. The left and right sides of the walking board body 1 are provided with mounting holes 2. A locking device is installed in the mounting holes 2. The locking device can lock the walking board body 1 onto the bracket.

[0033] In this embodiment, the walkway body 1 is made of molded sheet SMC composite material or molded block BMC composite material. The walkway body 1 is made of molding compound, and its weight is significantly lower than that of cement board and iron grating, approximately 1 / 3 the weight of cement board and 1 / 5 the weight of iron grating. It has high strength, corrosion resistance, and strong UV resistance. Due to its light weight, it is easy to transport, install, and carry, greatly saving installation time. Simultaneously, a locking device is provided on the walkway body 1 to lock it onto the support, ensuring that the lightweight, high-strength walkway is installed on the support and preventing it from being overturned under extreme weather conditions such as high-frequency vibration and strong winds, thus ensuring train traffic safety.

[0034] In this embodiment, the mounting hole 2 includes an upper section, a middle section, and a lower section. The diameter of the upper section is larger than the diameter of the middle section, and the diameter of the middle section is larger than the diameter of the lower section.

[0035] The locking device includes a screw 3, a locking nut 5, a locking tongue 6, a spring 7, and an anti-loosening cap 8. The screw 3 has a screw head 4 at its top end. The spring 7 is sleeved on the screw 3. The screw 3 movably passes through the middle section and the lower section. The screw head 4 is placed on the bottom wall of the upper section. The bottom end of the spring 7 contacts the bottom wall of the middle section, and the top end of the spring 7 contacts the screw head 4. The locking tongue 6 is sleeved on the screw 3.

[0036] The walking board body 1 is placed on the top wall of the support, the locking tongue 6 contacts the bottom wall of the support, and the locking nut 5 is threaded to the bottom of the screw 3. The locking nut 5 contacts the locking tongue 6, pressing the locking tongue 6 against the bottom wall of the support.

[0037] The anti-loosening cap 8 is fixed inside the upper section, and the anti-loosening cap 8 presses down on the screw head 4.

[0038] The specific locking principle is as follows: the walking plate body 1 is placed on the top wall of the bracket, the screw 3 passes through the middle and lower sections of the mounting hole 2, the screw head 4 is located on the bottom wall of the upper section, the locking tongue 6 is sleeved on the screw 3, and the locking nut 5 is threadedly connected to the screw 3. The locking nut 5 abuts against the locking tongue 6, causing the locking tongue 6 to contact the bottom wall of the bracket. Thus, the walking plate body 1 and the locking tongue 6 contact the top and bottom walls of the bracket respectively, clamping the bracket. Furthermore, this application includes a spring 7, which is sleeved on the screw 3. The two ends of the spring 7 contact the bottom wall of the middle section and the screw head 4 respectively. The spring 7 is in a compressed state and has elastic restoring force. The spring 7 applies an upward elastic restoring force to the screw head 4, thereby causing the screw 3 and the locking tongue 6 to be subjected to an upward force, making the locking tongue 6 press more tightly against the bottom wall of the bracket 4, resulting in a higher locking strength for the bracket.

[0039] In this embodiment, an anti-loosening cap 8 is provided, which has ventilation holes. The anti-loosening cap 8 is installed inside the upper section, pressing down the screw head 4 to prevent the screw 3 from rotating, thus preventing loosening, waterproofing, and preventing the locking device from being pulled by strong winds. The anti-loosening cap 8 is fixed to the upper section side wall by adhesive or interference fit.

[0040] In this embodiment, the bottom wall of the walking board body 1 is provided with a side baffle, which can contact the front or rear side wall of the locking tongue 6. In this embodiment, the side baffle is provided to limit the front or rear position of the locking tongue 6.

[0041] In this embodiment, the walking board body 1 has a left extension 9 on the left side, and a left groove 10 is formed on the bottom wall of the left extension 9. The walking board body 1 has a right extension 11 on the right side, and a right groove 12 is formed on the top wall of the right extension 11.

[0042] The portion of the right extension 11 of the left walking board body 1 located to the right of the right groove 12 can enter the left groove 10 of the left extension 9 of the right walking board body 1, and the portion of the left extension 9 of the right walking board body 1 located to the left of the left groove 10 can enter the right groove 12 of the right extension 11 of the left walking board body 1.

During installation, two adjacent walking board bodies 1 can be interlocked with each other, so that several walking board bodies 1 can be interlocked with each other, improving the overall strength and eliminating the screaming sound generated by strong winds passing through the joint.

[0044] In this embodiment, the bottom of the front and rear walls of the walking board body 1 are both provided with grooves, and shock-absorbing rubber pads can be placed in the grooves. The two shock-absorbing rubber pads can be pressed against the front and rear walls of the support respectively.

[0045] In this embodiment, grooves are opened at the bottom of the front and rear walls of the walking board body 1 to place shock-absorbing rubber pads. When in use, the shock-absorbing rubber pads are embedded in the grooves and protrude 1-2mm to press against the support, which plays a role in vibration reduction when the train passes by.

[0046] In this embodiment, the bottom wall of the pedestrian slab body 1 is provided with a plurality of main support ribs 13 and secondary support ribs 14. The main support ribs 13 and secondary support ribs 14 are provided in this embodiment to enhance the structural strength of the pedestrian slab body 1.

[0047] In this embodiment, the height of the main support rib 13 is 60-70mm, and the height of the secondary support rib 14 is 30-40mm.

[0048] In this embodiment, the top wall of the walking board body 1 is provided with an anti-slip pattern. The anti-slip pattern on the top wall of the walking board body 1 in this embodiment is 1.5mm thick, designed to increase friction and reduce the risk of falls when people walk on it.
