Abstract
Description
Technical Field
[0001] This utility model relates to the field of mine transportation safety technology, and in particular to an anti-slip device for ore trucks. Background Technology
[0002] The underground ore transport vehicle is a specialized transport device meticulously designed to adapt to the complex and unique operating environment of underground mines. These mines typically use horizontal tunnels as the main extraction and transport channels, with narrow spaces and limited height, placing extremely high demands on the size, maneuverability, and accessibility of the transport equipment. This specialized transport vehicle integrates a compact design, powerful motor, advanced operation, and comfortable and safe operation, providing strong support for underground mining and transportation.
[0003] In the existing use of ore transport vehicles, when parking on an incline, the weight of the vehicle and the ore inside the car can cause the vehicle to roll away. A rolling ore transport vehicle could directly collide with nearby workers, causing serious bodily injury. Furthermore, during the rollaway, the ore transport vehicle may collide with other vehicles, equipment, or tunnel walls, resulting in structural damage to the vehicle itself. After a rollaway incident, operations must be immediately stopped for accident handling and equipment repair, leading to production interruption and impacting the overall production efficiency of the mine.
[0004] To address the issue of ore trucks slipping down slopes, a contact structure is placed at the wheels to prevent this. This contact structure, by directly contacting the wheels, provides reliable friction or mechanical resistance, effectively preventing displacement caused by gravity or inertia. The contact structure also prevents the truck from colliding with the roadway walls or other equipment due to slippage, avoiding vehicle deformation, tire wear, or suspension system damage, thus extending the equipment's service life.
[0005] However, in the current use of contact blocks, the separate placement of the contact blocks from the vehicle body makes them prone to loss. Loss of contact blocks necessitates finding temporary alternatives or halting production, impacting transportation efficiency. In the event of an accident, production interruptions are even longer, leading to decreased output. Furthermore, the dispersed placement of contact blocks makes them easy to lose, requiring strengthened management and increasing management costs. Poor management could trigger a chain reaction of problems due to missing contact blocks. Utility Model Content
[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an anti-slip device for ore transport vehicles, which solves the problems of ore transport vehicles easily slipping and the collision block easily being lost.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] An anti-slippage device for a ore transport vehicle includes a shovel loader body structure, a locking structure, and an anti-slippage structure. The locking structure is located at the bottom of the shovel loader body structure, and the anti-slippage structure is located above the locking structure. The locking structure secures the anti-slippage structure, and the anti-slippage structure prevents the shovel loader body structure from slipping. The locking structure and the anti-slippage structure together prevent the shovel loader body structure from slipping and prevent the contact strip from shifting.
[0009] As a further improvement of this utility model, the loader body structure includes a cargo box body, four wheel bodies are symmetrically arranged at the bottom end of the cargo box body, and four hanging slots are symmetrically fixedly connected to the sides of the cargo box body. The hanging slots allow hooks to be attached to them, preventing the contact strip from obstructing the wheel bodies and thus reducing its blocking effect.
[0010] As a further improvement of this utility model, the locking structure includes eight fixing blocks. These eight fixing blocks are symmetrically fixed to the bottom of the truck body in pairs. Each pair of symmetrical fixing blocks has a sliding groove symmetrically fixed to its bottom end. A triangular block is slidably connected to the inner side of each pair of symmetrical sliding grooves that are close to each other. A connecting rod is fixedly connected to the inner side of each triangular block that is close to each other in the same direction. The triangular blocks allow the abutment strip to be placed at its top, thus achieving the effect of integrating the abutment strip with the main structure of the forklift truck.
[0011] As a further improvement of this utility model, each of the triangular blocks has a handle fixedly connected to the side away from the connecting rod. Each of the sliding grooves has a through groove on the side of the triangular blocks that are close to each other. Each of the triangular blocks has a telescopic rod fixedly connected to the side of the sliding groove closest to the inside. The end of the telescopic rod away from the triangular block is fixedly connected to the inner wall of the sliding groove. A spring is provided on the outside of each telescopic rod, and the two ends of the spring are respectively fixedly connected to the triangular block and the side of the sliding groove that are close to each other. The telescopic rod and springs allow the triangular blocks to rebound when the anti-slip structure moves upward.
[0012] As a further improvement of this utility model, the anti-slip structure includes two abutment strips, each positioned at the top of a triangular block. Each abutment strip has two symmetrically symmetrically formed pull-out grooves, and each pull-out groove has a slidingly connected abutment plate. A knob block is fixedly connected to the side of each abutment plate away from the interior of the abutment strip. The abutment strips effectively abut and secure the wheel body.
[0013] As a further improvement of this utility model, each of the knob blocks is rotatably connected to a rotating rod on the side away from the contact plate, and each of the rotating rods is fixedly connected to a hook on the side away from the knob block. Two connecting chains are fixedly connected to the top of each contact bar, and the ends of the connecting chains away from the contact bar are fixedly connected to the bottom of the carriage body. Rotation of the knob block and rotating rods allows the contact bar to be pulled out from the knob block, enabling the hooks to be hung in the hanging slots.
[0014] Compared with the prior art, the advantages of this utility model are as follows:
[0015] 1. The contact strip prevents the forklift's main structure from slipping, effectively avoiding collisions with nearby workers and ensuring their safety. Preventing slippage also avoids unnecessary property damage caused by collisions with auxiliary equipment. Furthermore, preventing slippage reduces the load on components, extends the equipment's lifespan, and thus lowers maintenance costs.
[0016] 2. Through the mounting groove, contact strip, and hook, the hook is attached to the mounting groove, and the contact strip precisely contacts the wheel body, ensuring even distribution of braking force. This prevents uneven force distribution due to misalignment, thereby improving braking efficiency and preventing the vehicle from rolling away. Furthermore, precise contact reduces vehicle tilt by evenly distributing braking force, improving parking stability. Attached Figure Description

Detailed Implementation
[0024] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0025] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to 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 herein are for illustrative purposes only and do not represent the only possible implementation.
[0026] See attached document Figure 1 -Appendix Figure 3 A ore truck anti-slip device includes a shovel truck body structure 100, a locking structure 200, an anti-slip structure 300, a hanging groove 103, a triangular block 203, a telescopic rod 207, a spring 208, an abutment strip 301, a rotating rod 305, a hook 306, and a connecting chain 307.
[0027] When this utility model is in use, if the loader body structure 100 is parked on an incline, to prevent it from rolling away, the two handles 205 are pulled apart. Driven by the handles 205, the triangular blocks 203 move into the sliding groove 202. Since the triangular blocks 203 are connected by a connecting rod 204, the movement of the handles 205 will cause all the triangular blocks 203 located on the same wheel body 102 to move into the sliding groove 202. Once all the triangular blocks 203 are inside the sliding groove 202, the abutment strip 301 at the top of the triangular blocks 203 will fall to the ground and then abut against the wheel body 102, thus preventing the loader body structure 100 from rolling away. A loader body structure 100 rolling away on an incline has strong kinetic energy, and if out of control, it is very likely to collide with nearby workers. Preventing it from rolling away effectively avoids such tragedies and ensures the safety of personnel. Furthermore, a runaway loader body structure 100 may collide with surrounding equipment, buildings, or vehicles; preventing runaway can avoid these unnecessary property losses. In the event of runaway, critical components of the loader body structure 100, such as the braking system and transmission system, will also bear enormous impact forces. Preventing runaway can reduce the burden on these components, extend the service life of the equipment, and lower maintenance costs.
[0028] When the contact strip 301 contacts the wheel body 102, the rotating rod 305, the knob block 304, and the contact plate 303 located inside the contact strip 301 are pulled out via the hook 306. When the contact plate 303 contacts the opening of the contact strip 301, the knob block 304 will protrude from the contact strip 301, thereby rotating the rotating rod 305 and the knob block 304, and hooking the hook 306 into the hanging groove 103. This prevents the contact strip 301 from shifting position relative to the wheel body 102, thus achieving precise contact with the wheel body 102. Precise contact ensures that the contact strip 301 is completely in contact with the wheel body 102, so that the braking force is evenly distributed, avoiding uneven force distribution due to offset, thereby improving braking efficiency and preventing the vehicle from rolling away. Moreover, positional offset may cause uneven force distribution during braking, increasing the possibility of rollover. Precise contact reduces vehicle tilt and improves parking stability by evenly distributing braking force. Precise contact can also prevent abnormal friction between the contact strip 301 and the wheel body 102 due to misalignment, reduce wear on braking components, and extend the service life of the contact strip 301, the wheel body 102, and the braking system.
[0029] When the contact is complete and the forklift body structure 100 needs to be activated, the hook 306 is removed from the mounting slot 103, and the rotating rod 305 is rotated to retract into the extraction slot 302. Then, the contact bar 301 is moved upward. When the contact bar 301 contacts the triangular block 203, continuing to move upward will cause the telescopic rod 207 and spring 208 to be squeezed by the triangular block 203. When the contact bar 301 is completely at the top of the triangular block 203, the triangular block 203 will support the contact bar 301 under the rebound of the telescopic rod 207 and spring 208, thus achieving the placement of the contact bar 301. Since the contact bar 301 and the bottom of the truck body 101 are fixed by the connecting chain 307, the contact bar 301 is stored, thus preventing the contact bar 301 from being lost. If the contact bar 301 is lost, time is required to find, replace, or repair it, which will interrupt the normal operation process and reduce operation efficiency. Preventing the loss of the contact strip 301 can avoid such time waste and improve work efficiency.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
