Description

Technical Field

[0001] This utility model relates to the field of horse transport technology, and in particular to a movable fence-protected ramp device that facilitates the loading and unloading of horses. Background Technology

[0002] Horse transportation and transhumance are core links in the regional livestock economy. The efficiency and safety of loading and unloading horses have become key bottlenecks restricting the large-scale and industrialized development of livestock farming in pastoral areas. Currently, loading and unloading operations for horses on transport vehicles in pastoral areas mostly still rely on temporary wooden planks laid out and joined together. These planks are typically simple, spliced ​​together to form an inclined channel, with one end directly against the ground and the other end resting on the edge of the truck bed or cargo compartment. Temporary stability is maintained by the weight of the planks themselves and contact friction. However, this method has gradually revealed the following drawbacks:

[0003] (1) Poor stability of the overlap; the two ends of the wooden board are directly overlapped with the ground and vehicles without any fixed or connecting structure. During use, it is easy to slip, tilt, or shift to the side, resulting in poor support stability. When horses go up or down, they are prone to instability and fall due to the displacement of the ramp.

[0004] (2) Poor safety protection effect; the wooden ramp is an open structure without side barriers, guardrails and anti-collision buffer structures. When horses are going up or down the ramp, they are very likely to deviate from the passage to the sides due to tension, fright, turning or shifting of center of gravity, which directly causes side fall, trampling and collision and other safety accidents, which can easily cause limb injury to horses and safety risks to personnel.

[0005] (3) Poor anti-slip performance; the surface of ordinary wooden boards is easily damp and worn. In complex environments such as rain, snow, mud, and sand in pastoral areas, the coefficient of friction drops sharply. When horses go up or down slopes, their hooves are prone to slipping and becoming unstable, which not only aggravates the horses' stress response, but also easily leads to serious safety problems such as falling, twisting, splitting, and dragging.

[0006] (4) The service life is short and it is inconvenient to move and transport. Temporary wooden planks have low load-bearing capacity. They are prone to bending, cracking, and loosening due to long-term impact from the weight of horses and repeated trampling. After high-frequency use, the breakage rate is high and frequent replacement is required. The reuse rate is low, the long-term use cost is high, and the continuity of operation is poor. In addition, the wooden plank ramps have no walking mechanism. In the scenario of scattered operations and multiple transfer operations in pastoral areas, manual handling and movement are extremely inconvenient, time-consuming and labor-intensive. Utility Model Content

[0007] In order to overcome the shortcomings of the prior art as mentioned above, in-depth research was conducted, and after a great deal of creative work, this utility model was completed.

[0008] Specifically, the technical problem to be solved by this utility model is to provide a movable fence-type protective ramp device that is easy for horses to load and unload, so as to solve the technical problems of the current wooden ramp structure, which has poor joint stability, safety protection effect and anti-slip performance, short service life and inconvenience in handling and moving.

[0009] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0010] A movable fence-protected ramp device for easy loading and unloading of horses includes a load-bearing frame, the bottom of which is provided with locking casters, and a ramp plate is fixedly installed on the top of which is the load-bearing frame. The ramp plate includes an integrally formed inclined section and a horizontal section. A ground overlap plate is hinged to the bottom end of the inclined section, and a truck bed overlap plate is hinged to the end of the horizontal section away from the inclined section.

[0011] The top two sides of the load-bearing frame are also equipped with protective fences. The ramp is located between the two protective fences, and the width of the ramp is adapted to the distance between the two protective fences. Each protective fence is hinged with an intercepting door at the end near the truck bed connecting plate. The intercepting door is located above the truck bed connecting plate, and there is a bolt between the two intercepting doors to connect them. When the intercepting door is in the open state, the intercepting door is located outside the protective fence and perpendicular to the protective fence.

[0012] As an improved technical solution, the load-bearing frame, the protective fence, and the intercepting gate are all frame structures made by welding several hollow rods together in sequence. There are four locking casters, which are located at the four corners of the bottom of the load-bearing frame, and the wheel surfaces of the locking casters are all provided with deep anti-slip textures.

[0013] As an improved technical solution, hand-cranked support legs are detachably installed on both sides of the bottom of the load-bearing frame. The hand-cranked support legs are located directly below the connection between the inclined section and the horizontal section, and the two hand-cranked support legs are arranged correspondingly.

[0014] As an improved technical solution, both sides of the bottom of the load-bearing frame are provided with support leg mounting seats. The support leg mounting seats are provided with first positioning holes. The hand-cranked support leg has a plug seat. The plug seat is provided with a second positioning hole along its circumference. The hand-cranked support leg is installed on the support leg mounting seats by positioning pins passing through the first positioning hole and the second positioning hole.

[0015] As an improved technical solution, one end of the ground overlap plate is hinged to the bottom end of the inclined section, and a lifting handle is provided on the back of the ground overlap plate. One end of the truck bed overlap plate is hinged to the end of the horizontal section away from the inclined section.

[0016] As an improved technical solution, the upper surface of the ramp slab and the front surface of the ground overlap slab are provided with a plurality of anti-slip rubber strips. The anti-slip rubber strips include a first anti-slip strip and a second anti-slip strip. The first anti-slip strips are arranged in two rows, and both rows of the first anti-slip strips are inclined. The two rows of the first anti-slip strips are evenly arranged along the length direction of the ramp slab and the ground overlap slab, respectively. The second anti-slip strips are arranged laterally, and the second anti-slip strips are located at the ends of the inclined section, the horizontal section and the ground overlap slab, respectively.

[0017] As an improved technical solution, the protective fence is an integrally formed structure of the load-bearing frame;

[0018] Alternatively, the protective fence is fixedly installed on the load-bearing frame using mounting bolts, and the protective fence is a foldable segmented structure, with adjacent segments of the protective fence connected by hinges.

[0019] As an improved technical solution, one end of the load-bearing frame is provided with a traction ring, which is detachably installed on the load-bearing frame through a threaded connection.

[0020] After adopting the above technical solution, the beneficial effects of this utility model are:

[0021] This movable fence-type ramp device, which facilitates the loading and unloading of horses, features a lightweight frame structure with high structural strength and a long service life. Equipped with locking casters, it allows for free movement, rapid relocation, and secure locking upon arrival. This design is well-suited for the dispersed operations and frequent relocations required in pastoral areas, improving the mobility of horse loading and unloading. In use, the device is moved to the horse exit point, and the horse transport vehicle is moved close to the device. The ground-mounted ramp is then lowered until it touches the ground. The barrier gates are then opened, with the ends furthest from the protective fence positioned close to the side railings of the transport vehicle. Finally, the truck bed ramp is unfolded, allowing the horses inside the fence to be driven onto the transport vehicle.

[0022] This movable fence-style ramp device facilitates the loading and unloading of horses on transport vehicles. The ramp slabs, through ground and truck bed overlap plates, can tightly connect with the ground and transport vehicle respectively, ensuring a smooth transition and preventing issues such as head tilting, side shifting, or slippage. This provides overall stability for horses going up and down the ramp, effectively preventing them from being startled or losing their balance due to ramp swaying. Simultaneously, the ramp slabs and the protective fences on both sides form a safe passage for horses, effectively preventing them from colliding, tipping over, or falling during the process. This makes horses more compliant when loading and unloading, significantly improving loading and unloading efficiency. Furthermore, the barrier gate, when opened, can connect with the fences on both sides of the transport vehicle to prevent horses from accidentally jumping out of the truck bed, thus effectively ensuring safety during the loading and unloading process.

[0036] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown in the figure, this embodiment provides a movable fence-type protective ramp device that facilitates loading and unloading of horses. It includes a load-bearing frame 1, with locking casters 2 at the bottom. These locking casters 2 are swivel casters with integrated braking / steering locking mechanisms, allowing for switching between free movement, directional straight movement, and stationary locking states. They are the core components enabling flexible movement and positioning of the device. In this embodiment, four locking casters 2 are located at the four corners of the bottom of the load-bearing frame 1, ensuring even force distribution and smooth movement of the device. Each locking caster 2 is equipped with a self-locking brake mechanism; stepping on it locks the device in place, preventing slippage. The wheel surfaces of the locking casters 2 are all textured with deep anti-slip grooves, with a friction coefficient ≥0.7. This deep-grooved anti-slip design provides strong grip and is suitable for grass, gravel roads, muddy surfaces, and other road conditions.

[0037] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a ramp 3 is fixedly installed on the top of the load-bearing frame 1. The ramp 3 is for horses to step on and pass through. The load-bearing frame 1 supports the ramp 3, ensuring that the ramp 3 can withstand repeated trampling and heavy impacts from the horses without bending or deforming. The ramp 3 includes an integrally formed inclined section 301 and a horizontal section 302. The inclined section 301 allows horses to smoothly go up and down, while the horizontal section 302 serves as a buffer platform, enabling better docking with the truck bed of the transport vehicle 15. It allows horses to pause briefly before entering the truck bed, adapting to the height and reducing the stress response caused by sudden ascent. To minimize the risk of startling and collisions, a ground overlap plate 4 is hinged at the bottom of the inclined section 301 for a smooth transition with the ground. A truck bed overlap plate 5 is hinged at the end of the horizontal section 302 away from the inclined section 301 for connecting with the truck bed of the transport vehicle 15. The ground overlap plate 4 and the truck bed overlap plate 5 are respectively connected to both ends of the ramp slab 3 by hinges, which can adaptively adjust the overlap angle according to the ground height and truck bed height. Within a certain range, it can meet the needs of overlapping between different ground heights and truck beds, ensuring a smooth transition and good horse passage.

[0038] Specifically, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in order to achieve the hinged installation of the ground overlap plate 4 and the truck bed overlap plate 5 at both ends of the ramp slab 3, one end of the ground overlap plate 4 is hinged to the bottom end of the inclined section 301, and the back of the ground overlap plate 4 is provided with a lifting handle 6, which makes it easy for people to manually flip the ground overlap plate 4 by lifting the handle 6, so as to realize the rapid unfolding of the ground overlap plate 4. One end of the truck bed overlap plate 5 is hinged to the end of the horizontal section 302 away from the inclined section 301, and can be freely flipped to adapt to transport vehicles 15 of different heights.

[0039] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, protective railings 7 are also provided on both sides of the top of the load-bearing frame 1. The ramp 3 is located between the two protective railings 7, and the width of the ramp 3 is adapted to the distance between the two protective railings 7. The ramp 3 and the protective railings 7 on both sides form a safe passage for horses to pass through, which can effectively prevent horses from rushing to the sides, overturning or falling during the process of going up and down the ramp.

[0040] In one embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the protective fence 7 is an integrally formed structure of the load-bearing frame 1, with high overall rigidity and good stability and anti-collision effect.

[0041] In another embodiment, such as Figure 5 and Figure 6 As shown, the protective fence 7 is a detachable and foldable structure. Specifically, the protective fence 7 is fixedly installed on the load-bearing frame 1 using mounting bolts. The installation and disassembly time is ≤5 minutes. The protective fence 7 is a foldable segmented structure, and adjacent segments of the protective fence 7 are connected by hinges. After the device is used, the protective fence 7 can be removed from the load-bearing frame 1 and then folded up, which can significantly reduce the storage and transportation space of the device and improve its portability.

[0042] To enhance the anti-collision effect of the protective fence 7, a buffer anti-collision strip can be installed on the inner side of the protective fence 7. The buffer anti-collision strip is made of elastic rubber or soft material, which can effectively buffer the impact force of the horse, reduce the horse's stress response, prevent the horse from scratching or bumping in the passage, and further improve the safety of loading and unloading.

[0043] like Figure 1 , Figure 2 , Figures 4 to 7As shown, each end of the protective fence 7 near the truck bed connecting plate 5 is hinged with an intercepting gate 8. The intercepting gate 8 is located above the truck bed connecting plate 5 and can be flipped outward around the hinge point. A latch 9 is provided between the two intercepting gates 8 to connect them. When the intercepting gate 8 is closed, the two intercepting gates 8 can be connected through the latch 9 to form an end barrier, preventing horses from jumping off the end of the device before the transport vehicle 15 arrives. Since the width of the device is much smaller than the width of the truck bed of the transport vehicle 15, there will be a large gap between the protective fence 7 and the side fences of the transport vehicle 15. In order to prevent horses in the truck bed from jumping off the gap, when the intercepting gate 8 is in the open state, the intercepting gate 8 is located outside the protective fence 7 and perpendicular to the protective fence 7. It can be connected with the side fences of the transport vehicle 15 to block the horses in the truck bed of the transport vehicle 15, preventing the horses from accidentally jumping off the truck bed, thereby effectively ensuring the safety of the horses during loading and unloading.

[0044] like Figure 1 , Figure 2 , Figures 4 to 6 As shown, the load-bearing frame 1, protective fence 7, and interception gate 8 are all frame structures made by welding several hollow poles together. The hollow poles are divided into main poles and auxiliary poles, with the main poles being 3mm thick and the auxiliary poles 2mm thick. They are rust-proofed and have a service life of ≥8 years in pastoral outdoor areas. Their weight is controlled within 80kg, facilitating single-person movement. This results in a lightweight, high-strength, impact-resistant, and durable device suitable for long-term, high-frequency use in pastoral areas. Combined with locking casters 2, the device can be freely pushed, quickly moved between areas, and locked securely in place. This adapts to the needs of dispersed operations and frequent relocations in pastoral areas, improving the mobility of horse loading and unloading operations. It is suitable for loading and unloading scenarios such as horse breeding, relocation, quarantine, trading, and race transport, and is particularly well-suited to complex operating environments such as pastures, gravel roads, and muddy surfaces in pastoral areas. In actual use, the single-person pushing speed is ≥1.5km / h, the turning radius is ≤2m, and there is no jamming or wheel slumping in complex terrain.

[0045] like Figures 1 to 5 As shown, both sides of the load-bearing frame 1 are detachably equipped with hand-cranked support legs 10. The hand-cranked support legs 10 are located directly below the connection between the inclined section 301 and the horizontal section 302, and the two hand-cranked support legs 10 are set accordingly. After the device is moved into place, the height of the hand-cranked support legs 10 is adjusted to make them stably supported on the ground. This is used to provide strong support for the position of the ramp with the greatest force, enhance the load-bearing capacity of the middle part of the ramp, effectively prevent the middle part of the ramp from sinking or deforming under pressure, and further improve the stability and safety of the horses' passage.

[0046] like Figures 1 to 5As shown, in order to install the hand-cranked support leg 10 on the load-bearing frame 1, both sides of the bottom of the load-bearing frame 1 are provided with support leg mounting seats 11. The support leg mounting seats 11 are provided with first positioning holes 1101. The upper part of the hand-cranked support leg 10 has an insert seat 12. The insert seat 12 is provided with second positioning holes 1201 along its circumference. The hand-cranked support leg 10 is installed on the support leg mounting seat 11 by positioning pins passing through the first positioning hole 1101 and the second positioning hole 1201. When loading and unloading horses, the hand-cranked support leg 10 is installed vertically on the load-bearing frame 1. The height of the hand-cranked support leg 10 can be adjusted by manually turning the crank handle to ensure it is stably supported on the ground. After loading and unloading the horses, the hand-cranked support leg 10 is adjusted so that its legs are lifted off the ground. Then, the positioning pin is pulled out, and the hand-cranked support leg 10 is rotated 90 degrees to keep it horizontal. Finally, the positioning pin is inserted. In this way, the hand-cranked support leg 10 can be stored on one side of the load-bearing frame 1 for easy movement of the device. When the device reaches a new working position, the hand-cranked support leg 10 is adjusted back to a vertical support state.

[0047] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, to improve the anti-slip performance of the ramp, several anti-slip rubber strips 13 are provided on the upper surface of the ramp slab 3 and the front of the ground overlap plate 4. The anti-slip rubber strips 13 are fixedly installed using anti-slip nails. The anti-slip rubber strips 13 include a first anti-slip strip 1301 and a second anti-slip strip 1302. The first anti-slip strip 1301 is provided in two rows, and both rows of the first anti-slip strip 1301 are inclined. The two rows of the first anti-slip strip 1301 are evenly arranged along the length direction of the ramp slab 3 and the ground overlap plate 4, respectively. The inclined first anti-slip strip 1301 can significantly increase the grip friction of the horse's hooves, and play an effective anti-slip and anti-fall effect. The second anti-slip strip 1302 is arranged laterally, and the second anti-slip strip 1302 is located at the ends of the inclined section 301, the horizontal section 302 and the ground overlap plate 4, respectively, and is laid in the areas not covered by the first anti-slip strip 1301. The anti-slip rubber strips 13 ensure that the anti-slip structure maintains excellent anti-slip performance even in harsh environments such as rain, snow, dampness, mud, and sandstorms, effectively preventing horses from slipping, splitting, becoming unstable, or falling.

[0048] like Figure 2 and Figure 4 As shown, a traction ring 14 is also provided at one end of the load-bearing frame 1. The traction ring 14 is located at the end of the load-bearing frame 1 near the truck bed connecting plate 5. The traction ring 14 is detachably installed on the load-bearing frame 1 by means of threaded connection. The device can be connected to the motor vehicle by a traction rope to realize long-distance transfer traction movement.

[0049] In this embodiment, the device is 3 meters long and 1.8 meters wide, suitable for Mongolian horses with a body width of 0.6-0.8 meters, with space reserved for two horses to walk side by side, a rated load capacity of 1000 kg, and can accommodate two adult Mongolian horses passing through at the same time. Of course, when the device is used for loading and unloading other livestock such as cattle, sheep, and pigs, the specifications and dimensions of the device can be adjusted accordingly.

[0050] In use, move the device to the horse exit position, depress the self-locking brake mechanism of the swivel wheel 2 to fix the device in place, then pull out the positioning pin, flip the hand-cranked support leg 10 to a vertical position, reinsert the positioning pin, and adjust the hand-cranked support leg 10 to ensure it is firmly supported on the ground. Next, reverse the horse transport vehicle 15 to a position close to the device and adjust its position so that the truck bed is aligned with the ramp. Finally, lower the ground overlap plate 4 so that it rests against the ground, open the intercepting gates 8 so that the ends of the two intercepting gates 8 furthest from the protective fence 7 are close to the side railings of the transport vehicle 15, and then unfold the truck bed overlap plate 5 so that it rests on the truck bed of the horse transport vehicle 15. Figure 7 As shown. In this way, the operator can smoothly drive the horses along the safe passage formed by the protective fence 7 into the transport vehicle 15 to complete the loading operation; the unloading operation is carried out in the reverse direction.

[0051] After loading and unloading, the truck bed overlap plate 5 and the ground overlap plate 4 are retracted in sequence, the interception door 8 is closed and locked with the bolt 9; the positioning bolt is pulled out, the hand-cranked support leg 10 is flipped over and stored and then the positioning bolt is reinserted; the locking state of the universal wheel 2 is released, and the device can be pushed to the next work point or storage area.

[0052] This movable fence-type ramp device, which facilitates loading and unloading of horses, provides convenience for loading and unloading horses onto the transport vehicle 15. The ramp slab 3 can be tightly connected to the ground and the transport vehicle 15 through the ground overlap plate 4 and the truck bed overlap plate 5, respectively. The overlap transition is smooth and there will be no problems such as head tilting, side shifting, or slippage. The horses are stable when going up and down the ramp, effectively preventing the horses from being startled or losing their balance due to ramp shaking. At the same time, the ramp slab 3 and the protective fences 7 on both sides form a safe passage for horses to pass through, which can effectively prevent horses from rushing to the sides, tipping over, or falling off during the process of going up and down the ramp, making the horses more obedient when getting on and off the transport vehicle 15, and greatly improving the loading and unloading efficiency of horses. In addition, after the intercepting gate 8 is opened, it can be connected to the fences on both sides of the transport vehicle 15 to block the horses in the truck bed of the transport vehicle 15, preventing the horses from accidentally jumping out of the truck bed, thereby effectively ensuring the safety of horses during the loading and unloading process.

[0053] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
