Description

Technical Field

[0001] This utility model mainly relates to the field of track technology, specifically to trolley tracks. Background Technology

[0002] In logistics loading and unloading, warehousing and handling, and special scenarios (such as earthquake rescue), trolleys are key tools for achieving efficient material transfer. However, in actual operations, there is a height difference between the ground and the trolley (usually 10-50cm), which becomes a major obstacle to trolley transfer and leads to many problems with existing operating methods.

[0003] In existing solutions, some scenarios involve manually lifting trolleys to cross height differences. However, this method is labor-intensive (requiring 2-3 people to work together for each lift) and prone to material falling or personnel injury due to uneven force application. This is especially true for trolleys carrying heavy goods (e.g., over 50kg), where operational efficiency is extremely low (each transfer takes ≥5 minutes). Other scenarios use simple ramps to assist in pushing, but traditional ramps are mostly single flat structures lacking fixing devices, making them prone to slippage during pushing (slippage rate approximately 15%). Furthermore, there is no transition structure at the connection between the ramp and the trolley / ground, allowing the trolley wheels to easily get stuck in gaps, leading to jamming or even wheel damage.

[0004] Furthermore, traditional ramps need to be stored separately when not in use, occupying interior space (approximately 0.5-1 m³) and lack convenient securing mechanisms. During vehicle operation, they are prone to rattling or collisions due to bumps, affecting driving safety. For scenarios involving frequent loading and unloading operations (such as express delivery and engineering material transfer), these issues reduce operational efficiency by more than 30%, while also increasing labor costs and safety risks. Utility Model Content

[0005] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing solutions are too simplistic. It mainly provides a trolley track to solve the technical problems mentioned in the background.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: The trolley track includes two sets of upper track pieces, one end of which is connected to the carriage via a hinge. The upper track pieces and the lower track pieces are fixedly connected, and a track reinforcement is installed between the lower track pieces. An internal frame is provided inside the carriage, and the trolley track is fixed to the internal frame by a latch when it is folded up.

[0007] Preferably, the upper and lower sections of the track are groove-shaped to match the movement of the trolley wheels, and a wear-resistant and anti-slip layer for use with the trolley wheels is fixedly provided on the contact side of the groove.

[0008] Preferably, the wear-resistant and anti-slip layer includes a first spacer and a second spacer arranged alternately, the first spacer and the second spacer dividing the wear-resistant and anti-slip layer into several intervals, and a blocking strip is installed at equal intervals within the intervals, and a polymer wear-resistant material layer is provided between the blocking strips.

[0009] Preferably, the outer ends of the upper and lower track pieces adopt an arc-shaped transition design.

[0010] Preferably, the track reinforcement members are distributed at intervals along the length of the trolley track, and the track reinforcement members are connected to the lower track piece by welding.

[0011] Preferably, one side of the internal frame has a groove that matches the trolley track.

[0012] Preferably, the latch includes a mounting plate, which is connected to the internal frame by bolts. A magnetic locking rod is slidably disposed on one side of the mounting plate and is mounted on one side of the T-shaped slider. The mounting plate has a groove that matches the T-shaped slider.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By using a grooved cross-section design for the upper and lower rail sections, the trolley wheels are guided and restricted when traveling within the grooved rail, preventing lateral deviation or swaying, thereby improving the stability of the trolley when pushing.

[0014] The trolley track is connected to the carriage by a hinge at one end, and is secured by the grooves in the internal frame and the magnetic locking rod of the latch. This allows for flexible switching between unfolding and folding of the trolley track and stable storage, thus saving carriage space.

[0015] The grid frame of the first and second partitions and the staggered distribution of the blocking strips, combined with the filling and covering of the polymer wear-resistant material layer, form a continuous and complete anti-slip contact interface, thereby avoiding the jerking caused by local slippage or jamming when the trolley wheels travel in the grooved track, and ensuring the smoothness of the trolley process.

[0016] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0019] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] Please refer to the appendix carefully. Figure 1-5The trolley track 1 includes two sets of upper track pieces 2, which are welded together with lower track pieces 4. There is a certain angle between the upper track pieces 2 and the lower track pieces 4, which makes it easy for the upper track pieces 2 to fit against the mounting surface of the carriage 3. The cross-section of the upper track pieces 2 and the lower track pieces 4 is a groove shape that matches the movement of the trolley wheels. The trolley wheels are placed in the grooved track, and the grooved structure guides the wheels, as if setting an invisible track boundary for the wheels, limiting the lateral deviation or swaying of the wheels during operation. The outer ends of the upper track pieces 2 and the lower track pieces 4 adopt an arc transition design. The arc transition design improves the safety during use. The ends of traditional tracks are sharp right angles. When the trolley travels to the end of the track or when people work around it, the sharp ends are easy to scratch or damage the trolley wheels, and may even cause safety hazards such as scratches to people.

[0023] A wear-resistant and anti-slip layer 7 is fixedly installed on the groove-shaped contact side for use with the trolley wheels. The wear-resistant and anti-slip layer 7 includes a first spacer 71 and a second spacer 72 arranged in an alternating pattern. The first spacer 71 and the second spacer 72 are integrally injection molded from a high-strength reinforced polymer material such as glass fiber reinforced nylon. The two are distributed perpendicularly and alternately to form a regular grid-like frame. The first spacer 71 and the second spacer 72 divide the wear-resistant and anti-slip layer 7 into several sections, and a blocking strip 73 is installed at equal intervals in each section. The spacing between adjacent blocking strips 73 is 20-40mm, forming a continuous anti-slip tooth structure. The gaps between the blocking strips 73 are filled with a polymer wear-resistant material layer 74. The material is a high-hardness polyurethane elastomer with a Shore hardness of 85-90A. It is tightly bonded to the grid frame through an injection molding process. The surface is flush with the top of the blocking strips 73 to form a complete anti-slip contact surface. Wear-resistant particles such as alumina micro powder are added inside the polymer wear-resistant material layer 74 to further improve the surface wear resistance.

[0024] Track reinforcement 5 is installed between the lower track pieces 4. The track reinforcement 5 is distributed at intervals along the length of the trolley track 1, and the track reinforcement 5 is connected to the lower track pieces 4 by welding. The track reinforcement 5 can enhance the structural strength and rigidity between the lower track pieces 4, and at the same time, it can distribute part of the load to prevent the lower track pieces 4 from bending, deforming or even breaking due to excessive local stress.

[0025] One end of the upper track 2 is connected to the carriage 3 via a hinge 21. The hinge 21 is fixed 100 degrees inward from the outer end of the carriage 3, allowing the trolley track 1 to rotate around the hinge 21 axis, achieving flexible switching between unfolding and retracting. An inner frame 31 is provided on the inner side of the carriage 3. A groove matching the trolley track 1 is provided on one side of the inner frame 31. When retracted, the trolley track 1 can be accurately embedded into the groove to form a preliminary positioning. When the trolley track 1 is in the retracted state, it is fixed to the inner frame 31 by a latch 6.

[0026] The latch 6 includes a mounting plate 61, which is connected to the inner frame 31 by bolts. A magnetic locking rod 62 is slidably provided on one side of the mounting plate 61 and is installed on the side of the T-shaped slider. A magnetic block that attracts the magnetic locking rod 62 is installed on the trolley track 1. A groove matching the T-shaped slider is provided on the mounting plate 61.

[0027] The specific operating procedure of this utility is as follows: When the trolley track 1 needs to be used, push the magnetic locking rod 62 of the latch 6 to slide it away from the trolley track 1. After unlocking, hold the end of the trolley track 1 and rotate the trolley track 1 outward from the groove of the inner frame 31 with the hinge 21 as the rotation axis until the other end of the trolley track 1 contacts the ground, forming a slope connecting the carriage 3 and the ground. The slope can be adjusted adaptively according to the height difference, usually from 15° to 30°. At this time, the lower part of the track 4 contacts the ground, and the track reinforcement 5 forms an integral support due to the welding connection, ensuring that the track does not wobble.

[0028] When the trolley track 1 is not in use, hold the end of the trolley track 1 and rotate it in the opposite direction around the hinge 21 to fold the trolley track 1 upwards until the entire trolley track 1 is embedded in the groove of the inner frame 31. The groove matches the shape of the track. Push the magnetic locking rod 62 to slide along the slide groove, so that the magnetic locking rod 62 moves to one side of the trolley track 1. When it moves to the designated position, the magnetic locking rod 62 will be magnetically attracted to the trolley track 1, thereby limiting the position of the magnetic locking rod 62.

[0029] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
