Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cargo transportation, and in particular relates to a wheel set track for cargo transportation on stair ramps. Background Technology
[0002] In the engineering industry, it is common to encounter situations where heavy objects need to be transported through narrow stairwells and ramps. Due to the narrow dimensions of the stairwells, it is impossible to transport heavy objects manually. This is especially true in petrochemical plants with explosion-proof requirements, where windows are not allowed due to building explosion-proof regulations. The only way to transport heavy objects upstairs is through stairwells and ramps.
[0003] In the petrochemical industry, to ensure the safety of operators and DCS / SIS control systems, explosion-proof buildings are used for external control rooms and server rack rooms near production units. Some server rack rooms are located on the second floor, and when new racks need to be installed, the only way to transport them is via staircases and ramps. Since the racks weigh 300-500 kg, are 2 meters high, and 750-800 mm wide, manually moving these heavy racks up narrow staircases can easily cause injury or damage to the racks, and is also time-consuming and labor-intensive. Therefore, a new equipment needs to be designed. Utility Model Content
[0004] The purpose of this invention is to provide a wheel set track for transporting goods on stair ramps, in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A wheel track for transporting goods on a stair ramp includes several crossbeams for connection and fixation, and a support device for rolling and supporting goods upwards. Two support devices are symmetrically arranged, and the crossbeams are evenly installed between the two support devices. Some of the crossbeams are equipped with anti-backflow devices to prevent goods from sliding down. The support device includes a keel support, on which several rollers and support feet are installed. The rollers and support feet are evenly distributed along the length of the keel support, and an anti-slip component is provided at the bottom of the keel support. The anti-backflow device includes a fixed seat, and a stop bar assembly is installed in the middle of the fixed seat.
[0007] Furthermore: the anti-slip component includes anti-slip legs, the bottom surface of which is attached with an anti-slip pad, and the anti-slip legs are rotatably connected to the keel support.
[0008] Furthermore: the keel support is a two-lobed symmetrical structure, using two galvanized angle steels with a diameter of ∠50×50×5, and the rollers and the support feet are installed between the two galvanized angle steels.
[0009] Furthermore, the stop rod assembly includes a backstop rod, the bottom end of which is provided with a counterweight, and the backstop rod and the fixed base are rotatably connected.
[0010] Furthermore: the anti-reverse rod is square-shaped, the counterweight is cylindrical, and the anti-reverse rod and the counterweight are integrally formed.
[0011] Furthermore, the rollers are made of nylon material, have a diameter of 100 mm, and a spacing of 20 cm.
[0012] Furthermore, two anti-reverse devices are symmetrically installed along the length of each of the crossbeams.
[0013] Compared with existing technologies, the beneficial effects are:
[0014] Using mechanical rollers instead of manual handling reduces labor intensity and improves work efficiency. Furthermore, the addition of anti-reverse devices reduces the risk of goods accidentally slipping, enhancing safety. This is particularly advantageous for narrow staircases and for overweight or oversized cargo. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-5 A wheel set track for transporting goods on a stair ramp includes several crossbeams 2 for connection and fixation, and a support device for rolling and supporting the goods upward. Two support devices are symmetrically arranged, and the crossbeams 2 are evenly installed between the two support devices. Some of the crossbeams 2 are equipped with anti-reverse devices to prevent the goods from sliding down. Two anti-reverse devices are symmetrically installed along the length of each crossbeam 2.
[0023] In this embodiment: the supporting device includes a keel bracket 101, on which a plurality of rollers 102 and support feet 103 are mounted. The rollers 102 and support feet 103 are evenly distributed along the length of the keel bracket 101. The rollers 102 are made of nylon material, have a diameter of 100 mm, and are spaced 20 cm apart. An anti-slip component is provided at the bottom of the keel bracket 101. The anti-slip component includes anti-slip legs 104, and an anti-slip pad 105 is attached to the bottom surface of the anti-slip legs 104. The anti-slip legs 104 and the keel bracket 101 are rotatably connected. 101 has a two-part symmetrical structure, using two galvanized angle steels with a diameter of ∠50×50×5. Rollers 102 and support feet 103 are installed between the two galvanized angle steels. The keel support 101 is placed along the stair ramp, and the support feet 103 are placed on the steps to ensure that the keel support 101 is balanced and to avoid damaging the steps. Then, the anti-slip legs 104 are rotated, and the anti-slip pads 105 support the ground to keep the keel support 101 stable. The goods are pushed along the keel support 101 and moved up the stair ramp with the support of the rollers 102.
[0024] In this embodiment: the anti-reverse device includes a fixed base 301, and a stop rod assembly is installed in the middle of the fixed base 301; the stop rod assembly includes an anti-reverse rod 302, and a counterweight 303 is provided at the bottom end of the anti-reverse rod 302. The anti-reverse rod 302 and the fixed base 301 are rotatably connected; the anti-reverse rod 302 is square columnar, and the counterweight 303 is cylindrical. The anti-reverse rod 302 and the counterweight 303 are integrally formed; when passing the crossbeam 2, the goods press down on the anti-reverse rod 302. Under the support of the fixed base 301, the anti-reverse rod 302 lifts the counterweight 303 and rotates it below the support surface of the keel support 101. After the goods pass over the anti-reverse rod 302, the anti-reverse rod 302 flips under the gravity of the counterweight 303 and protrudes above the support surface of the keel support 101. If the goods accidentally slip, they will be blocked by the anti-reverse rod 302 that has just passed, preventing them from continuing to slip.
[0025] Working principle: The keel support 101 is placed along the stair ramp, with the support legs 103 resting on the steps to ensure the keel support 101 is balanced and to avoid damaging the steps. Then, the anti-slip legs 104 are rotated, and the anti-slip pads 105 support the ground to keep the keel support 101 stable. The crossbeam 2 is then installed between the two keel supports 101 with bolts to ensure overall stability. Then, the goods are pushed along the keel support 101 and moved up the stair ramp with the support of the rollers 102. When the goods pass the crossbeam 2, the goods press down on the anti-reverse bar 302. With the support of the fixed seat 301, the anti-reverse bar 302 lifts the counterweight 303 and rotates it below the support surface of the keel support 101. After the goods pass the anti-reverse bar 302, the anti-reverse bar 302 flips under the weight of the counterweight 303 and protrudes above the support surface of the keel support 101. If the goods accidentally slip, they will be blocked by the anti-reverse bar 302 that has just been passed, preventing them from slipping further.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
